8d6bcddf60 Add S3 volume encryption support with -s3.encryptVolumeData flag (#7890)
* Add S3 volume encryption support with -s3.encryptVolumeData flag

This change adds volume-level encryption support for S3 uploads, similar
to the existing -filer.encryptVolumeData option. Each chunk is encrypted
with its own auto-generated CipherKey when the flag is enabled.

Changes:
- Add -s3.encryptVolumeData flag to weed s3, weed server, and weed mini
- Wire Cipher option through S3ApiServer and ChunkedUploadOption
- Add integration tests for multi-chunk range reads with encryption
- Tests verify encryption works across chunk boundaries

Usage:
  weed s3 -encryptVolumeData
  weed server -s3 -s3.encryptVolumeData
  weed mini -s3.encryptVolumeData

Integration tests:
  go test -v -tags=integration -timeout 5m ./test/s3/sse/...

* Add GitHub Actions CI for S3 volume encryption tests

- Add test-volume-encryption target to Makefile that starts server with -s3.encryptVolumeData
- Add s3-volume-encryption job to GitHub Actions workflow
- Tests run with integration build tag and 10m timeout
- Server logs uploaded on failure for debugging

* Fix S3 client credentials to use environment variables

The test was using hardcoded credentials "any"/"any" but the Makefile
sets AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY to "some_access_key1"/
"some_secret_key1". Updated getS3Client() to read from environment
variables with fallback to "any"/"any" for manual testing.

* Change bucket creation errors from skip to fatal

Tests should fail, not skip, when bucket creation fails. This ensures
that credential mismatches and other configuration issues are caught
rather than silently skipped.

* Make copy and multipart test jobs fail instead of succeed

Changed exit 0 to exit 1 for s3-sse-copy-operations and s3-sse-multipart
jobs. These jobs document known limitations but should fail to ensure
the issues are tracked and addressed, not silently ignored.

* Hardcode S3 credentials to match Makefile

Changed from environment variables to hardcoded credentials
"some_access_key1"/"some_secret_key1" to match the Makefile
configuration. This ensures tests work reliably.

* fix Double Encryption

* fix Chunk Size Mismatch

* Added IsCompressed

* is gzipped

* fix copying

c260e6a22e Fix issue #7880: Tasks use Volume IDs instead of ip:port (#7881)
* Fix issue #7880: Tasks use Volume IDs instead of ip:port

When volume servers are registered with custom IDs, tasks were attempting
to connect using the ID instead of the actual ip:port address, causing
connection failures.

Modified task detection logic in balance, erasure coding, and vacuum tasks
to resolve volume server IDs to their actual ip:port addresses using
ActiveTopology information.

* Use server addresses directly instead of translating from IDs

Modified VolumeHealthMetrics to include ServerAddress field populated
directly from topology DataNodeInfo.Address. Updated task detection
logic to use addresses directly without runtime lookups.

Changes:
- Added ServerAddress field to VolumeHealthMetrics
- Updated maintenance scanner to populate ServerAddress
- Modified task detection to use ServerAddress for Node fields
- Updated DestinationPlan to include TargetAddress
- Removed runtime address lookups in favor of direct address usage

* Address PR comments: add ServerAddress field, improve error handling

- Add missing ServerAddress field to VolumeHealthMetrics struct
- Add warning in vacuum detection when server not found in topology
- Improve error handling in erasure coding to abort task if sources missing
- Make vacuum task stricter by skipping if server not found in topology

* Refactor: Extract common address resolution logic into shared utility

- Created weed/worker/tasks/util/address.go with ResolveServerAddress function
- Updated balance, erasure_coding, and vacuum detection to use the shared utility
- Removed code duplication and improved maintainability
- Consistent error handling across all task types

* Fix critical issues in task address resolution

- Vacuum: Require topology availability and fail if server not found (no fallback to ID)
- Ensure all task types consistently fail early when topology is incomplete
- Prevent creation of tasks that would fail due to missing server addresses

* Address additional PR feedback

- Add validation for empty addresses in ResolveServerAddress
- Remove redundant serverAddress variable in vacuum detection
- Improve robustness of address resolution

* Improve error logging in vacuum detection

- Include actual error details in log message for better diagnostics
- Make error messages consistent with other task types

e8a41ec053 Fix the issue where fuse command on a node cannot specify multiple configuration directory paths (#7874)
Changes:
    Modified weed/command/fuse.go to add a function GetFuseCommandName to return the name of the fuse command.
    Modified weed/weed.go to conditionally initialize the global HTTP client only if the command is not "fuse".
    Modified weed/command/fuse_std.go to parse parameters and ensure the global HTTP client is initialized for the fuse command.

Tests:
  Use /etc/fstab like:
  fuse /repos fuse.weed filer=192.168.1.101:7202,filer.path=/hpc/repos,config_dir=/etc/seaweedfs/seaweedfs_01 0 0

2f6aa98221 Refactor: Replace removeDuplicateSlashes with NormalizeObjectKey (#7873)
* Replace removeDuplicateSlashes with NormalizeObjectKey

Use s3_constants.NormalizeObjectKey instead of removeDuplicateSlashes in most places
for consistency. NormalizeObjectKey handles both duplicate slash removal and ensures
the path starts with '/', providing more complete normalization.

* Fix double slash issues after NormalizeObjectKey

After using NormalizeObjectKey, object keys have a leading '/'. This commit ensures:
- getVersionedObjectDir strips leading slash before concatenation
- getEntry calls receive names without leading slash
- String concatenation with '/' doesn't create '//' paths

This prevents path construction errors like:
  /buckets/bucket//object  (wrong)
  /buckets/bucket/object   (correct)

* ensure object key leading "/"

* fix compilation

* fix: Strip leading slash from object keys in S3 API responses

After introducing NormalizeObjectKey, all internal object keys have a
leading slash. However, S3 API responses must return keys without
leading slashes to match AWS S3 behavior.

Fixed in three functions:
- addVersion: Strip slash for version list entries
- processRegularFile: Strip slash for regular file entries
- processExplicitDirectory: Strip slash for directory entries

This ensures ListObjectVersions and similar APIs return keys like
'bar' instead of '/bar', matching S3 API specifications.

* fix: Normalize keyMarker for consistent pagination comparison

The S3 API provides keyMarker without a leading slash (e.g., 'object-001'),
but after introducing NormalizeObjectKey, all internal object keys have
leading slashes (e.g., '/object-001').

When comparing keyMarker < normalizedObjectKey in shouldSkipObjectForMarker,
the ASCII value of '/' (47) is less than 'o' (111), causing all objects
to be incorrectly skipped during pagination. This resulted in page 2 and
beyond returning 0 results.

Fix: Normalize the keyMarker when creating versionCollector so comparisons
work correctly with normalized object keys.

Fixes pagination tests:
- TestVersioningPaginationOver1000Versions
- TestVersioningPaginationMultipleObjectsManyVersions

* refactor: Change NormalizeObjectKey to return keys without leading slash

BREAKING STRATEGY CHANGE:
Previously, NormalizeObjectKey added a leading slash to all object keys,
which required stripping it when returning keys to S3 API clients and
caused complexity in marker normalization for pagination.

NEW STRATEGY:
- NormalizeObjectKey now returns keys WITHOUT leading slash (e.g., 'foo/bar' not '/foo/bar')
- This matches the S3 API format directly
- All path concatenations now explicitly add '/' between bucket and object
- No need to strip slashes in responses or normalize markers

Changes:
1. Modified NormalizeObjectKey to strip leading slash instead of adding it
2. Fixed all path concatenations to use:
   - BucketsPath + '/' + bucket + '/' + object
   instead of:
   - BucketsPath + '/' + bucket + object
3. Reverted response key stripping in:
   - addVersion()
   - processRegularFile()
   - processExplicitDirectory()
4. Reverted keyMarker normalization in findVersionsRecursively()
5. Updated matchesPrefixFilter() to work with keys without leading slash
6. Fixed paths in handlers:
   - s3api_object_handlers.go (GetObject, HeadObject, cacheRemoteObjectForStreaming)
   - s3api_object_handlers_postpolicy.go
   - s3api_object_handlers_tagging.go
   - s3api_object_handlers_acl.go
   - s3api_version_id.go (getVersionedObjectDir, getVersionIdFormat)
   - s3api_object_versioning.go (getObjectVersionList, updateLatestVersionAfterDeletion)

All versioning tests pass including pagination stress tests.

* adjust format

* Update post policy tests to match new NormalizeObjectKey behavior

- Update TestPostPolicyKeyNormalization to expect keys without leading slashes
- Update TestNormalizeObjectKey to expect keys without leading slashes
- Update TestPostPolicyFilenameSubstitution to expect keys without leading slashes
- Update path construction in tests to use new pattern: BucketsPath + '/' + bucket + '/' + object

* Fix ListObjectVersions prefix filtering

Remove leading slash addition to prefix parameter to allow correct filtering
of .versions directories when listing object versions with a specific prefix.

The prefix parameter should match entry paths relative to bucket root.
Adding a leading slash was breaking the prefix filter for paginated requests.

Fixes pagination issue where second page returned 0 versions instead of
continuing with remaining versions.

* no leading slash

* Fix urlEscapeObject to add leading slash for filer paths

NormalizeObjectKey now returns keys without leading slashes to match S3 API format.
However, urlEscapeObject is used for filer paths which require leading slashes.
Add leading slash back after normalization to ensure filer paths are correct.

Fixes TestS3ApiServer_toFilerPath test failures.

* adjust tests

* normalize

* Fix: Normalize prefixes and markers in LIST operations using NormalizeObjectKey

Ensure consistent key normalization across all S3 operations (GET, PUT, LIST).
Previously, LIST operations were not applying the same normalization rules
(handling backslashes, duplicate slashes, leading slashes) as GET/PUT operations.

Changes:
- Updated normalizePrefixMarker() to call NormalizeObjectKey for both prefix and marker
- This ensures prefixes with leading slashes, backslashes, or duplicate slashes are
  handled consistently with how object keys are normalized
- Fixes Parquet test failures where pads.write_dataset creates implicit directory
  structures that couldn't be discovered by subsequent LIST operations
- Added TestPrefixNormalizationInList and TestListPrefixConsistency tests

All existing LIST tests continue to pass with the normalization improvements.

* Add debugging logging to LIST operations to track prefix normalization

* Fix: Remove leading slash addition from GetPrefix to work with NormalizeObjectKey

The NormalizeObjectKey function removes leading slashes to match S3 API format
(e.g., 'foo/bar' not '/foo/bar'). However, GetPrefix was adding a leading slash
back, which caused LIST operations to fail with incorrect path handling.

Now GetPrefix only normalizes duplicate slashes without adding a leading slash,
which allows NormalizeObjectKey changes to work correctly for S3 LIST operations.

All Parquet integration tests now pass (20/20).

* Fix: Handle object paths without leading slash in checkDirectoryObject

NormalizeObjectKey() removes the leading slash to match S3 API format.
However, checkDirectoryObject() was assuming the object path has a leading
slash when processing directory markers (paths ending with '/').

Now we ensure the object has a leading slash before processing it for
filer operations.

Fixes implicit directory marker test (explicit_dir/) while keeping
Parquet integration tests passing (20/20).

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* Fix: Handle explicit directory markers with trailing slashes

Explicit directory markers created with put_object(Key='dir/', ...) are stored
in the filer with the trailing slash as part of the name. The checkDirectoryObject()
function now checks for both:
1. Explicit directories: lookup with trailing slash preserved (e.g., 'explicit_dir/')
2. Implicit directories: lookup without trailing slash (e.g., 'implicit_dir')

This ensures both types of directory markers are properly recognized.

All tests pass:
- Implicit directory tests: 6/6 (including explicit directory marker test)
- Parquet integration tests: 20/20

* Fix: Preserve trailing slash in NormalizeObjectKey

NormalizeObjectKey now preserves trailing slashes when normalizing object keys.
This is important for explicit directory markers like 'explicit_dir/' which rely
on the trailing slash to be recognized as directory objects.

The normalization process:
1. Notes if trailing slash was present
2. Removes duplicate slashes and converts backslashes
3. Removes leading slash for S3 API format
4. Restores trailing slash if it was in the original

This ensures explicit directory markers created with put_object(Key='dir/', ...)
are properly normalized and can be looked up by their exact name.

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* clean object

* Fix: Don't restore trailing slash if result is empty

When normalizing paths that are only slashes (e.g., '///', '/'), the function
should return an empty string, not a single slash. The fix ensures we only
restore the trailing slash if the result is non-empty.

This fixes the 'just_slashes' test case:
- Input: '///'
- Expected: ''
- Previous: '/'
- Fixed: ''

All tests now pass:
- Unit tests: TestNormalizeObjectKey (13/13)
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* prefixEndsOnDelimiter

* Update s3api_object_handlers_list.go

* Update s3api_object_handlers_list.go

014027f75a Fix: Support object tagging in versioned buckets (Issue #7868) (#7871)
* Fix: Support object tagging in versioned buckets (Issue #7868)

This fix addresses the issue where setting tags on files in versioned buckets would fail with 'filer: no entry is found in filer store' error.

Changes:
- Updated GetObjectTaggingHandler to check versioning status and retrieve correct object versions
- Updated PutObjectTaggingHandler to properly locate and update tags on versioned objects
- Updated DeleteObjectTaggingHandler to delete tags from versioned objects
- Added proper handling for both specific versions and latest versions
- Added distinction between null versions (pre-versioning objects) and versioned objects

The fix follows the same versioning-aware pattern already implemented in ACL handlers.

Tests:
- Added comprehensive test suite for tagging operations on versioned buckets
- Tests cover PUT, GET, and DELETE tagging operations on specific versions and latest versions
- Tests verify tag isolation between different versions of the same object

* Fix: Ensure consistent directory path construction in tagging handlers

Changed directory path construction to match the pattern used in ACL handlers:
- Added missing '/' before object path when constructing .versions directory path
- This ensures compatibility with the filer's expected path structure
- Applied to both PutObjectTaggingHandler and DeleteObjectTaggingHandler

* Revert: Remove redundant slash in path construction - object already has leading slash from NormalizeObjectKey

* Fix: Remove redundant slashes in versioning path construction across handlers

- getVersionedObjectDir: object already starts with '/', no need for extra '/'
- ACL handlers: same pattern, fix both PutObjectAcl locations
- Ensures consistent path construction with object parameter normalization

* fix test compilation

* Add: Comprehensive ACL tests for versioned and non-versioned buckets

- Added s3_acl_versioning_test.go with 5 test cases covering:
  * GetObjectAcl on versioned buckets
  * GetObjectAcl on specific versions
  * PutObjectAcl on versioned buckets
  * PutObjectAcl on specific versions
  * Independent ACL management across versions

These tests were missing and would have caught the path construction
issues we just fixed in the ACL handler. Tests validate that ACL
operations work correctly on both versioned and non-versioned objects.

* Fix: Correct tagging versioning test file formatting

* fix: Update AWS SDK endpoint config and improve cleanup to handle delete markers

- Replace deprecated EndpointResolverWithOptions with BaseEndpoint in AWS SDK v2 client configuration
- Update cleanupTestBucket to properly delete both object versions and delete markers
- Apply changes to both ACL and tagging test files for consistency

* Fix S3 multi-delete for versioned objects

The bug was in getVersionedObjectDir() which was constructing paths without
a slash between the bucket and object key:

BEFORE (WRONG): /buckets/mybucket{key}.versions
AFTER (FIXED):  /buckets/mybucket/{key}/.versions

This caused version deletions to claim success but not actually delete files,
breaking S3 compatibility tests:
- test_versioning_multi_object_delete
- test_versioning_multi_object_delete_with_marker
- test_versioning_concurrent_multi_object_delete
- test_object_lock_multi_delete_object_with_retention

Added comprehensive test that reproduces the issue and verifies the fix.

* Remove emojis from test output

7f611f5d3a fix: Correct admin server port in Helm worker deployment (#7872)
The worker deployment was incorrectly passing the admin gRPC port (33646)
to the -admin flag. However, the SeaweedFS worker command automatically
calculates the gRPC port by adding 10000 to the HTTP port provided.

This caused workers to attempt connection to port 43646 (33646 + 10000)
instead of the correct gRPC port 33646 (23646 + 10000).

Changes:
- Update worker-deployment.yaml to use admin.port instead of admin.grpcPort
- Workers now correctly connect to admin HTTP port, allowing the binary
  to calculate the gRPC port automatically

Fixes workers failing with:
"dial tcp <admin-ip>:43646: connect: no route to host"

Related:
- Worker code: weed/pb/grpc_client_server.go:272 (grpcPort = port + 10000)
- Worker docs: weed/command/worker.go:36 (admin HTTP port + 10000)

26acebdef1 fix: restore TimeToFirstByte metric for S3 GetObject operations (issue #7869) (#7870)
* fix(iam): add support for fine-grained S3 actions in IAM policies

Add support for fine-grained S3 actions like s3:DeleteObject, s3:PutObject,
and other specific S3 actions in IAM policy mapping. Previously, only
coarse-grained action patterns (Put*, Get*, etc.) were supported, causing
IAM policies with specific actions to be rejected with 'not a valid action'
error.

Fixes issue #7864 part 2: s3:DeleteObject IAM action is now supported.

Changes:
- Extended MapToStatementAction() to handle fine-grained S3 actions
- Maps S3-specific actions to appropriate internal action constants
- Supports 30+ S3 actions including DeleteObject, PutObject, GetObject, etc.

* fix(s3api): correct resource ARN generation for subpath permissions

Fix convertSingleAction() to properly handle subpath patterns in legacy
actions. Previously, when a user was granted Write permission to a subpath
(e.g., Write:bucket/sub_path/*), the resource ARN was incorrectly generated,
causing DELETE operations to be denied even though s3:DeleteObject was
included in the Write action.

The fix:
- Extract bucket name and prefix path separately from patterns like
  'bucket/prefix/*'
- Generate correct S3 ARN format: arn:aws:s3:::bucket/prefix/*
- Ensure all permission checks (Read, Write, List, Tagging, etc.) work
  correctly with subpaths
- Support nested paths (e.g., bucket/a/b/c/*)

Fixes issue #7864 part 1: Write permission on subpath now allows DELETE.

Example:
- Permission: Write:mybucket/documents/*
- Objects can now be: PUT, DELETE, or ACL operations on mybucket/documents/*
- Objects outside this path are still denied

* test(s3api): add comprehensive tests for subpath permission handling

Add new test file with comprehensive tests for convertSingleAction():

1. TestConvertSingleActionDeleteObject: Verifies s3:DeleteObject is
   included in Write actions (fixes issue #7864 part 2)

2. TestConvertSingleActionSubpath: Tests proper resource ARN generation
   for different permission patterns:
   - Bucket-level: Write:mybucket -> arn:aws:s3:::mybucket
   - Wildcard: Write:mybucket/* -> arn:aws:s3:::mybucket/*
   - Subpath: Write:mybucket/sub_path/* -> arn:aws:s3:::mybucket/sub_path/*
   - Nested: Read:mybucket/documents/* -> arn:aws:s3:::mybucket/documents/*

3. TestConvertSingleActionSubpathDeleteAllowed: Specifically validates
   that subpath Write permissions allow DELETE operations

4. TestConvertSingleActionNestedPaths: Tests deeply nested path handling
   (e.g., bucket/a/b/c/*)

All tests pass and validate the fixes for issue #7864.

* fix: address review comments from PR #7865

- Fix critical bug: use parsed 'bucket' instead of 'resourcePattern' for GetObjectRetention, GetObjectLegalHold, and PutObjectLegalHold actions to avoid malformed ARNs like arn:aws:s3:::bucket/*/*
- Refactor large switch statement in MapToStatementAction() into a map-based lookup for better performance and maintainability

* fmt

* refactor: extract extractBucketAndPrefix helper and simplify convertSingleAction

- Extract extractBucketAndPrefix as a package-level function for better testability and reusability
- Remove unused bucketName parameter from convertSingleAction signature
- Update GetResourcesFromLegacyAction to use the extracted helper for consistent ARN generation
- Update all call sites in tests to match new function signature
- All tests pass and module compiles without errors

* fix: use extracted bucket variable consistently in all ARN generation branches

Replace resourcePattern with extracted bucket variable in else branches and bucket-level cases to avoid malformed ARNs like 'arn:aws:s3:::mybucket/*/*':

- Read case: bucket-level else branch
- Write case: bucket-level else branch
- Admin case: both bucket and object ARNs
- List case: bucket-level else branch
- GetBucketObjectLockConfiguration: bucket extraction
- PutBucketObjectLockConfiguration: bucket extraction

This ensures consistent ARN format: arn:aws:s3:::bucket or arn:aws:s3:::bucket/*

* fix: address remaining review comments from PR #7865

High priority fixes:
- Write action on bucket-level now generates arn:aws:s3:::mybucket/* instead of
  arn:aws:s3:::mybucket to enable object-level S3 actions (s3:PutObject, s3:DeleteObject)
- GetResourcesFromLegacyAction now generates both bucket and object ARNs for /*
  patterns to maintain backward compatibility with mixed action groups

Medium priority improvements:
- Remove unused 'bucket' field from TestConvertSingleActionSubpath test struct
- Update test to use assert.ElementsMatch instead of assert.Contains for more
  comprehensive resource ARN validation
- Clarify test expectations with expectedResources slice instead of single expectedResource

All tests pass, compilation verified

* test: improve TestConvertSingleActionNestedPaths with comprehensive assertions

Update test to use assert.ElementsMatch for more robust resource ARN verification:
- Change struct from single expectedResource to expectedResources slice
- Update Read nested path test to expect both bucket and prefix ARNs
- Use assert.ElementsMatch to verify all generated resources match exactly
- Provides complete coverage for nested path handling

This matches the improvement pattern used in TestConvertSingleActionSubpath

* refactor: simplify S3 action map and improve resource ARN detection

- Refactor fineGrainedActionMap to use init() function for programmatic population of both prefixed (s3:Action) and unprefixed (Action) variants, eliminating 70+ duplicate entries
- Add buildObjectResourceArn() helper to eliminate duplicated resource ARN generation logic across switch cases
- Fix bucket vs object-level access detection: only use HasSuffix(/*) check instead of Contains('/') which incorrectly matched patterns like 'bucket/prefix' without wildcard
- Apply buildObjectResourceArn() consistently to Tagging, BypassGovernanceRetention, GetObjectRetention, PutObjectRetention, GetObjectLegalHold, and PutObjectLegalHold cases

* fmt

* fix: generate object-level ARNs for bucket-level read access

When bucket-level read access is granted (e.g., 'Read:mybucket'),
generate both bucket and object ARNs so that object-level actions
like s3:GetObject can properly authorize.

Similarly, in GetResourcesFromLegacyAction, bucket-level patterns
should generate both ARN levels for consistency with patterns that
include wildcards. This ensures that users with bucket-level
permissions can read objects, not just the bucket itself.

* fix: address Copilot code review comments

- Remove unused bucketName parameter from ConvertIdentityToPolicy signature
  - Update all callers in examples.go and engine_test.go
  - Bucket is now extracted from action string itself

- Update extractBucketAndPrefix documentation
  - Add nested path example (bucket/a/b/c/*)
  - Clarify that prefix can contain multiple path segments

- Make GetResourcesFromLegacyAction action-aware
  - Different action types have different resource requirements
  - List actions only need bucket ARN (bucket-only operations)
  - Read/Write/Tagging actions need both bucket and object ARNs
  - Aligns with convertSingleAction logic for consistency

All tests pass successfully

* test: add comprehensive tests for GetResourcesFromLegacyAction consistency

- Add TestGetResourcesFromLegacyAction to verify action-aware resource generation
- Validate consistency with convertSingleAction for all action types:
  * List actions: bucket-only ARNs (s3:ListBucket is bucket-level operation)
  * Read actions: both bucket and object ARNs
  * Write actions: object-only ARNs (subpaths) or object ARNs (bucket-level)
  * Admin actions: both bucket and object ARNs
- Update GetResourcesFromLegacyAction to generate Admin ARNs consistent with convertSingleAction
- All tests pass (35+ test cases across integration_test.go)

* refactor: eliminate code duplication in GetResourcesFromLegacyAction

- Simplify GetResourcesFromLegacyAction to delegate to convertSingleAction
- Eliminates ~50 lines of duplicated action-type-specific logic
- Ensures single source of truth for resource ARN generation
- Improves maintainability: changes to ARN logic only need to be made in one place
- All tests pass: any inconsistencies would be caught immediately
- Addresses Gemini Code Assist review comment about code duplication

* fix: remove fragile 'dummy' action type in CreatePolicyFromLegacyIdentity

- Replace hardcoded 'dummy:' prefix with proper representative action type
- Use first valid action type from the action list to determine resource requirements
- Ensures GetResourcesFromLegacyAction receives a valid action type
- Prevents silent failures when convertSingleAction encounters unknown action
- Improves code clarity: explains why representative action type is needed
- All tests pass: policy engine tests verify correct behavior

* security: prevent privilege escalation in Admin action subpath handling

- Admin action with subpath (e.g., Admin:bucket/admin/*) now correctly restricts
  to the specified subpath instead of granting full bucket access
- If prefix exists: resources restricted to bucket + bucket/prefix/*
- If no prefix: full bucket access (unchanged behavior for root Admin)
- Added test case Admin_on_subpath to validate the security fix
- All 40+ policy engine tests pass

* refactor: address Copilot code review comments on S3 authorization

- Fix GetObjectTagging mapping: change from ACTION_READ to ACTION_TAGGING
  (tagging operations should not be classified as general read operations)

- Enhance extractBucketAndPrefix edge case handling:
  - Add input validation (reject empty strings, whitespace, slash-only)
  - Normalize double slashes and trailing slashes
  - Return empty bucket/prefix for invalid patterns
  - Prevent generation of malformed ARNs

- Separate Read action from ListBucket (AWS S3 IAM semantics):
  - ListBucket is a bucket-level operation, not object-level
  - Read action now only includes s3:GetObject, s3:GetObjectVersion
  - This aligns with AWS S3 IAM policy best practices

- Update buildObjectResourceArn to handle invalid bucket names gracefully:
  - Return empty slice if bucket is empty after validation
  - Prevents malformed ARN generation

- Add comprehensive TestExtractBucketAndPrefixEdgeCases with 8 test cases:
  - Validates empty strings, whitespace, special characters
  - Confirms proper normalization of double/trailing slashes
  - Ensures robust parsing of nested paths

- Update existing tests to reflect removed ListBucket from Read action

All 40+ policy engine tests pass

* fix: aggregate resource ARNs from all action types in CreatePolicyFromLegacyIdentity

CRITICAL FIX: The previous implementation incorrectly used a single representative
action type to determine resource ARNs when multiple legacy actions targeted the
same resource pattern. This caused incorrect policy generation when action types
with different resource requirements (e.g., List vs Write) were grouped together.

Example of the bug:
- Input: List:mybucket/path/*, Write:mybucket/path/*
- Old behavior: Used only List's resources (bucket-level ARN)
- Result: Policy had Write actions (s3:PutObject) but only bucket ARN
- Consequence: s3:PutObject would be denied due to missing object-level ARN

Solution:
- Iterate through all action types for a given resource pattern
- For each action type, call GetResourcesFromLegacyAction to get required ARNs
- Aggregate all ARNs into a set to eliminate duplicates
- Use the merged set for the final policy statement
- Admin action short-circuits (always includes full permissions)

Example of correct behavior:
- Input: List:mybucket/path/*, Write:mybucket/path/*
- New behavior: Aggregates both List and Write resource requirements
- Result: Policy has Write actions with BOTH bucket and object-level ARNs
- Outcome: s3:PutObject works correctly on mybucket/path/*

Added TestCreatePolicyFromLegacyIdentityMultipleActions with 3 test cases:
1. List + Write on subpath: verifies bucket + object ARN aggregation
2. Read + Tagging on bucket: verifies action-specific ARN combinations
3. Admin with other actions: verifies Admin dominates resource ARNs

All 45+ policy engine tests pass

* fix: remove bucket-level ARN from Read action for consistency

ISSUE: The Read action was including bucket-level ARNs (arn:aws:s3:::bucket)
even though the only S3 actions in Read are s3:GetObject and s3:GetObjectVersion,
which are object-level operations. This created a mismatch between the actions
and resources in the policy statement.

ROOT CAUSE: s3:ListBucket was previously removed from the Read action, but the
bucket-level ARN was not removed, creating an inconsistency.

SOLUTION: Update Read action to only generate object-level ARNs using
buildObjectResourceArn, consistent with how Write and Tagging actions work.

This ensures:
- Read:mybucket generates arn:aws:s3:::mybucket/* (not bucket ARN)
- Read:bucket/prefix/* generates arn:aws:s3:::bucket/prefix/* (object-level only)
- Consistency: same actions, same resources, same logic across all object operations

Updated test expectations:
- TestConvertSingleActionSubpath: Read_on_subpath now expects only object ARN
- TestConvertSingleActionNestedPaths: Read nested path now expects only object ARN
- TestConvertIdentityToPolicy: Read resources now 1 instead of 2
- TestCreatePolicyFromLegacyIdentityMultipleActions: Read+Tagging aggregates to 1 ARN

All 45+ policy engine tests pass

* doc

* fmt

* fix: address Copilot code review on Read action consistency and missing S3 action mappings

- Clarify MapToStatementAction comment to reflect exact lookup (not pattern matching)
- Add missing S3 actions to baseS3ActionMap:
  - ListBucketVersions, ListAllMyBuckets for bucket operations
  - GetBucketCors, PutBucketCors, DeleteBucketCors for CORS
  - GetBucketNotification, PutBucketNotification for notifications
  - GetBucketObjectLockConfiguration, PutBucketObjectLockConfiguration for object lock
  - GetObjectVersionTagging for version tagging
  - GetObjectVersionAcl, PutBucketAcl for ACL operations
  - PutBucketTagging, DeleteBucketTagging for bucket tagging

- Fix Read action scope inconsistency with GetActionMappings():
  - Previously: only included GetObject, GetObjectVersion
  - Now: includes full Read set (14 actions) from GetActionMappings
  - Includes both bucket-level (ListBucket*, GetBucket*) and object-level (GetObject*) ARNs
  - Bucket ARN enables ListBucket operations, object ARN enables GetObject operations

- Update all test expectations:
  - TestConvertSingleActionSubpath: Read now returns 2 ARNs (bucket + objects)
  - TestConvertSingleActionNestedPaths: Read nested path now includes bucket ARN
  - TestGetResourcesFromLegacyAction: Read test cases updated for consistency
  - TestCreatePolicyFromLegacyIdentityMultipleActions: Read_and_Tagging now returns 2 ARNs

  - Previously: only object-level (GetObjectTagging, PutObjectTagging, DeleteObjectTagging)
  - Now: includes bucket-level (GetBucketTagging, PutBucketTagging, DeleteBucketTagging)
  - Generates both bucket and object ARNs to support bucket-level operations

- Add bucket validation to prevent malformed ARNs:
  - Admin: return error if bucket is empty
  - List: generate empty resources if bucket is empty
  - Tagging: check bucket before generating ARNs
  - GetBucketObjectLockConfiguration, PutBucketObjectLockConfiguration: validate bucket

- Fix TrimRight issue in extractBucketAndPrefix:
  - Change from strings.TrimRight(pattern, "/") to remove only one trailing slash
  - Prevents loss of prefix when pattern has multiple trailing slashes

- Update all test cases:
  - TestConvertSingleActionSubpath: Write now returns 16 actions and bucket+object ARNs
  - TestConvertSingleActionNestedPaths: Write includes bucket ARN
  - TestGetResourcesFromLegacyAction: Updated Write and Tagging expectations
  - TestCreatePolicyFromLegacyIdentityMultipleActions: Updated action/resource counts

Fixes: Inconsistencies between convertSingleAction and GetActionMappings for Write/List/Tagging actions

* fmt

* fix: resolve ListMultipartUploads/ListParts mapping inconsistency and add action validation

- Fix ListMultipartUploads and ListParts mapping in helpers.go:
  - Changed from ACTION_LIST to ACTION_WRITE for consistency with GetActionMappings
  - These operations are part of the multipart write workflow and should map to Write action
  - Prevents inconsistent behavior when same actions processed through different code paths

- Add documentation to clarify multipart operations in Write action:
  - Explain why ListMultipartUploads and ListParts are part of Write permissions
  - These are required for meaningful multipart upload workflow management

- Add action validation to CreatePolicyFromLegacyIdentity:
  - Validates action format before processing using ValidateActionMapping
  - Logs warnings for invalid actions instead of silently skipping them
  - Provides clearer error messages when invalid action types are used
  - Ensures users know when their intended permissions weren't applied
  - Consistent with ConvertLegacyActions validation approach

5469b7c58f fix: resolve inconsistent S3 API authorization for DELETE operations (issue #7864) (#7865)
* fix(iam): add support for fine-grained S3 actions in IAM policies

Add support for fine-grained S3 actions like s3:DeleteObject, s3:PutObject,
and other specific S3 actions in IAM policy mapping. Previously, only
coarse-grained action patterns (Put*, Get*, etc.) were supported, causing
IAM policies with specific actions to be rejected with 'not a valid action'
error.

Fixes issue #7864 part 2: s3:DeleteObject IAM action is now supported.

Changes:
- Extended MapToStatementAction() to handle fine-grained S3 actions
- Maps S3-specific actions to appropriate internal action constants
- Supports 30+ S3 actions including DeleteObject, PutObject, GetObject, etc.

* fix(s3api): correct resource ARN generation for subpath permissions

Fix convertSingleAction() to properly handle subpath patterns in legacy
actions. Previously, when a user was granted Write permission to a subpath
(e.g., Write:bucket/sub_path/*), the resource ARN was incorrectly generated,
causing DELETE operations to be denied even though s3:DeleteObject was
included in the Write action.

The fix:
- Extract bucket name and prefix path separately from patterns like
  'bucket/prefix/*'
- Generate correct S3 ARN format: arn:aws:s3:::bucket/prefix/*
- Ensure all permission checks (Read, Write, List, Tagging, etc.) work
  correctly with subpaths
- Support nested paths (e.g., bucket/a/b/c/*)

Fixes issue #7864 part 1: Write permission on subpath now allows DELETE.

Example:
- Permission: Write:mybucket/documents/*
- Objects can now be: PUT, DELETE, or ACL operations on mybucket/documents/*
- Objects outside this path are still denied

* test(iam): add tests for fine-grained S3 action mappings

Extend TestMapToStatementAction with test cases for fine-grained S3 actions:
- s3:DeleteObject
- s3:PutObject
- s3:GetObject
- s3:ListBucket
- s3:PutObjectAcl
- s3:GetObjectAcl

Ensures the new action mapping support is working correctly.

* test(s3api): add comprehensive tests for subpath permission handling

Add new test file with comprehensive tests for convertSingleAction():

1. TestConvertSingleActionDeleteObject: Verifies s3:DeleteObject is
   included in Write actions (fixes issue #7864 part 2)

2. TestConvertSingleActionSubpath: Tests proper resource ARN generation
   for different permission patterns:
   - Bucket-level: Write:mybucket -> arn:aws:s3:::mybucket
   - Wildcard: Write:mybucket/* -> arn:aws:s3:::mybucket/*
   - Subpath: Write:mybucket/sub_path/* -> arn:aws:s3:::mybucket/sub_path/*
   - Nested: Read:mybucket/documents/* -> arn:aws:s3:::mybucket/documents/*

3. TestConvertSingleActionSubpathDeleteAllowed: Specifically validates
   that subpath Write permissions allow DELETE operations

4. TestConvertSingleActionNestedPaths: Tests deeply nested path handling
   (e.g., bucket/a/b/c/*)

All tests pass and validate the fixes for issue #7864.

* fix: address review comments from PR #7865

- Fix critical bug: use parsed 'bucket' instead of 'resourcePattern' for GetObjectRetention, GetObjectLegalHold, and PutObjectLegalHold actions to avoid malformed ARNs like arn:aws:s3:::bucket/*/*
- Refactor large switch statement in MapToStatementAction() into a map-based lookup for better performance and maintainability

* fmt

* refactor: extract extractBucketAndPrefix helper and simplify convertSingleAction

- Extract extractBucketAndPrefix as a package-level function for better testability and reusability
- Remove unused bucketName parameter from convertSingleAction signature
- Update GetResourcesFromLegacyAction to use the extracted helper for consistent ARN generation
- Update all call sites in tests to match new function signature
- All tests pass and module compiles without errors

* fix: use extracted bucket variable consistently in all ARN generation branches

Replace resourcePattern with extracted bucket variable in else branches and bucket-level cases to avoid malformed ARNs like 'arn:aws:s3:::mybucket/*/*':

- Read case: bucket-level else branch
- Write case: bucket-level else branch
- Admin case: both bucket and object ARNs
- List case: bucket-level else branch
- GetBucketObjectLockConfiguration: bucket extraction
- PutBucketObjectLockConfiguration: bucket extraction

This ensures consistent ARN format: arn:aws:s3:::bucket or arn:aws:s3:::bucket/*

* fix: address remaining review comments from PR #7865

High priority fixes:
- Write action on bucket-level now generates arn:aws:s3:::mybucket/* instead of
  arn:aws:s3:::mybucket to enable object-level S3 actions (s3:PutObject, s3:DeleteObject)
- GetResourcesFromLegacyAction now generates both bucket and object ARNs for /*
  patterns to maintain backward compatibility with mixed action groups

Medium priority improvements:
- Remove unused 'bucket' field from TestConvertSingleActionSubpath test struct
- Update test to use assert.ElementsMatch instead of assert.Contains for more
  comprehensive resource ARN validation
- Clarify test expectations with expectedResources slice instead of single expectedResource

All tests pass, compilation verified

* test: improve TestConvertSingleActionNestedPaths with comprehensive assertions

Update test to use assert.ElementsMatch for more robust resource ARN verification:
- Change struct from single expectedResource to expectedResources slice
- Update Read nested path test to expect both bucket and prefix ARNs
- Use assert.ElementsMatch to verify all generated resources match exactly
- Provides complete coverage for nested path handling

This matches the improvement pattern used in TestConvertSingleActionSubpath

* refactor: simplify S3 action map and improve resource ARN detection

- Refactor fineGrainedActionMap to use init() function for programmatic population of both prefixed (s3:Action) and unprefixed (Action) variants, eliminating 70+ duplicate entries
- Add buildObjectResourceArn() helper to eliminate duplicated resource ARN generation logic across switch cases
- Fix bucket vs object-level access detection: only use HasSuffix(/*) check instead of Contains('/') which incorrectly matched patterns like 'bucket/prefix' without wildcard
- Apply buildObjectResourceArn() consistently to Tagging, BypassGovernanceRetention, GetObjectRetention, PutObjectRetention, GetObjectLegalHold, and PutObjectLegalHold cases

* fmt

* fix: generate object-level ARNs for bucket-level read access

When bucket-level read access is granted (e.g., 'Read:mybucket'),
generate both bucket and object ARNs so that object-level actions
like s3:GetObject can properly authorize.

Similarly, in GetResourcesFromLegacyAction, bucket-level patterns
should generate both ARN levels for consistency with patterns that
include wildcards. This ensures that users with bucket-level

1261e93ef2 fix: comprehensive go vet error fixes and add CI enforcement (#7861)
* fix: use keyed fields in struct literals

- Replace unsafe reflect.StringHeader/SliceHeader with safe unsafe.String/Slice (weed/query/sqltypes/unsafe.go)
- Add field names to Type_ScalarType struct literals (weed/mq/schema/schema_builder.go)
- Add Duration field name to FlexibleDuration struct literals across test files
- Add field names to bson.D struct literals (weed/filer/mongodb/mongodb_store_kv.go)

Fixes go vet warnings about unkeyed struct literals.

* fix: remove unreachable code

- Remove unreachable return statements after infinite for loops
- Remove unreachable code after if/else blocks where all paths return
- Simplify recursive logic by removing unnecessary for loop (inode_to_path.go)
- Fix Type_ScalarType literal to use enum value directly (schema_builder.go)
- Call onCompletionFn on stream error (subscribe_session.go)

Files fixed:
- weed/query/sqltypes/unsafe.go
- weed/mq/schema/schema_builder.go
- weed/mq/client/sub_client/connect_to_sub_coordinator.go
- weed/filer/redis3/ItemList.go
- weed/mq/client/agent_client/subscribe_session.go
- weed/mq/broker/broker_grpc_pub_balancer.go
- weed/mount/inode_to_path.go
- weed/util/skiplist/name_list.go

* fix: avoid copying lock values in protobuf messages

- Use proto.Merge() instead of direct assignment to avoid copying sync.Mutex in S3ApiConfiguration (iamapi_server.go)
- Add explicit comments noting that channel-received values are already copies before taking addresses (volume_grpc_client_to_master.go)

The protobuf messages contain sync.Mutex fields from the message state, which should not be copied.
Using proto.Merge() properly merges messages without copying the embedded mutex.

* fix: correct byte array size for uint32 bit shift operations

The generateAccountId() function only needs 4 bytes to create a uint32 value.
Changed from allocating 8 bytes to 4 bytes to match the actual usage.

This fixes go vet warning about shifting 8-bit values (bytes) by more than 8 bits.

* fix: ensure context cancellation on all error paths

In broker_client_subscribe.go, ensure subscriberCancel() is called on all error return paths:
- When stream creation fails
- When partition assignment fails
- When sending initialization message fails

This prevents context leaks when an error occurs during subscriber creation.

* fix: ensure subscriberCancel called for CreateFreshSubscriber stream.Send error

Ensure subscriberCancel() is called when stream.Send fails in CreateFreshSubscriber.

* ci: add go vet step to prevent future lint regressions

- Add go vet step to GitHub Actions workflow
- Filter known protobuf lock warnings (MessageState sync.Mutex)
  These are expected in generated protobuf code and are safe
- Prevents accumulation of go vet errors in future PRs
- Step runs before build to catch issues early

* fix: resolve remaining syntax and logic errors in vet fixes

- Fixed syntax errors in filer_sync.go caused by missing closing braces

- All services now share the single metrics port (9327) and single debug port (6060)
- Consistent pattern with master, filer, volume, webdav services

* fix(worker): fix variable shadowing in health check handler

- Rename http.ResponseWriter parameter from 'w' to 'rw' to avoid shadowing
  the outer 'w *worker.Worker' parameter
- Prevents potential bugs if future code tries to use worker state in handler
- Improves code clarity and follows Go best practices

* fix(worker): remove unused worker parameter in metrics server

- Change 'w *worker.Worker' parameter to '_' as it's not used
- Clarifies intent that parameter is intentionally unused

621ff124f0 fix: ensure Helm chart is published only after container images are available (#7859)
fix: consolidate Helm chart release with container image build

Resolve issue #7855 by consolidating the Helm chart release workflow
with the container image build workflow. This ensures perfect alignment:

1. Container images are built and pushed to GHCR
2. Images are copied from GHCR to Docker Hub
3. Helm chart is published only after step 2 completes

Previously, the Helm chart was published immediately on tag push before
images were available in Docker Hub, causing deployment failures.

Changes:
- Added helm-release job to container_release_unified.yml that depends
  on copy-to-dockerhub job
- Removed helm_chart_release.yml workflow (consolidated into unified release)

Benefits:
- No race conditions between image push and chart publication
- Users can deploy immediately after release
- Single source of truth for release process
- Clearer job dependencies and execution flow

9c784cf9e2 fix: use path to handle urls in weed admin file browser (#7858)
* fix: use path instead of filepath to handle urls in weed admin file browser

* test: add comprehensive tests for file browser path handling

- Test breadcrumb generation for various path scenarios
- Test path handling with forward slashes (URL compatibility)
- Test parent path calculation for Windows compatibility
- Test file extension handling using path.Ext
- Test bucket path detection logic

These tests verify that the switch from filepath to path package works
correctly and handles URLs properly across all platforms.

* refactor: simplify fullPath construction using path.Join

Replace verbose manual path construction with path.Join which:
- Handles trailing slashes automatically
- Is more concise and readable
- Is more robust for edge cases

* fix: normalize path in ShowFileBrowser and rename generateBreadcrumbs parameter

Critical fix:
- Add util.CleanWindowsPath() normalization to path parameter in ShowFileBrowser
  handler, matching the pattern used in other file operation handlers
  (lines 273, 464)
- This ensures Windows-style backslashes are converted to forward slashes
  before processing, fixing path handling issues on Windows

Consistency improvement:
- Rename path parameter to dir in generateBreadcrumbs function
- Aligns with parameter rename in GetFileBrowser for consistent naming
  throughout the file

* test: improve coverage for Windows path handling and production code behavior

Address reviewer feedback by enhancing test quality:

1. Improved test documentation:
   - Added clear comments explaining what each test validates
   - Clarified that some tests validate expected behavior vs production code
   - Documented the Windows path normalization flow

2. Enhanced actual production code testing:
   - TestGenerateBreadcrumbs: Calls actual production function
   - TestBreadcrumbPathFormatting: Validates production output format
   - TestDirectoryNavigation: Integration-style test for complete flow

3. Added new test functions for better coverage:
   - TestPathJoinHandlesEdgeCases: Verifies path.Join behavior
   - TestWindowsPathNormalizationBehavior: Documents expected normalization
   - TestDirectoryNavigation: Complete navigation flow test

4. Improved test organization:
   - Fixed duplicate field naming issues
   - Better test names for clarity
   - More comprehensive edge case coverage

These improvements ensure the fix for issue #7628 (Windows path handling)
is properly validated across the complete flow from handler to path logic.

* test: use actual util.CleanWindowsPath function in Windows path normalization test

Address reviewer feedback by testing the actual production function:
- Import util package for CleanWindowsPath
- Call the real util.CleanWindowsPath() instead of reimplementing logic
- Ensures test validates actual implementation, not just expected behavior
- Added more test cases for edge cases (simple path, deep nesting)

This change validates that the Windows path normalization in the
ShowFileBrowser handler (handlers/file_browser_handlers.go:64)
works correctly with the actual util.CleanWindowsPath function.

* style: fix indentation in TestPathJoinHandlesEdgeCases

Align t.Errorf statement inside the if block with proper indentation.
The error message now correctly aligns with the if block body,
maintaining consistent indentation throughout the function.

* test: restore backslash validation check in TestPathJoinHandlesEdgeCases

2567be8040 refactor: remove unused gRPC connection age parameters (#7852)
The GrpcMaxConnectionAge and GrpcMaxConnectionAgeGrace constants have a troubled
history - they were removed in 2022 due to gRPC issues, reverted later, and
recently re-added. However, they are not essential to the core worker reconnection
fix which was solved through proper goroutine ordering.

The Docker Swarm DNS handling mentioned in the comments is not critical, and
these parameters have caused problems in the past. Removing them simplifies
the configuration without losing functionality.

14df5d1bb5 fix: improve worker reconnection robustness and prevent handleOutgoing hang (#7838)
* feat: add automatic port detection and fallback for mini command

- Added port availability detection using TCP binding tests
- Implemented port fallback mechanism searching for available ports
- Support for both HTTP and gRPC port handling
- IP-aware port checking using actual service bind address
- Dual-interface verification (specific IP and wildcard 0.0.0.0)
- All services (Master, Volume, Filer, S3, WebDAV, Admin) auto-reallocate to available ports
- Enables multiple mini instances to run simultaneously without conflicts

* fix: use actual bind IP for service health checks

- Previously health checks were hardcoded to localhost (127.0.0.1)
- This caused failures when services bind to actual IP (e.g., 10.21.153.8)
- Now health checks use the same IP that services are binding to
- Fixes Volume and other service health check failures on non-localhost IPs

* refactor: improve port detection logic and remove gRPC handling duplication

- findAvailablePortOnIP now returns 0 on failure instead of unavailable port
  Allows callers to detect when port finding fails and handle appropriately

- Remove duplicate gRPC port handling from ensureAllPortsAvailableOnIP
  All gRPC port logic is now centralized in initializeGrpcPortsOnIP

- Log final port configuration only after all ports are finalized
  Both HTTP and gRPC ports are now correctly initialized before logging

- Add error logging when port allocation fails
  Makes debugging easier when ports can't be found

* refactor: fix race condition and clean up port detection code

- Convert parallel HTTP port checks to sequential to prevent race conditions
  where multiple goroutines could allocate the same available port
- Remove unused 'sync' import since WaitGroup is no longer used
- Add documentation to localhost wrapper functions explaining they are
  kept for backwards compatibility and future use
- All gRPC port logic is now exclusively handled in initializeGrpcPortsOnIP
  eliminating any duplication in ensureAllPortsAvailableOnIP

* refactor: address code review comments - constants, helper function, and cleanup

- Define GrpcPortOffset constant (10000) to replace magic numbers throughout
  the code for better maintainability and consistency
- Extract bindIp determination logic into getBindIp() helper function
  to eliminate code duplication between runMini and startMiniServices
- Remove redundant 'calculatedPort = calculatedPort' assignment that had no effect
- Update all gRPC port calculations to use GrpcPortOffset constant
  (lines 489, 886 and the error logging at line 501)

* refactor: remove unused wrapper functions and update documentation

- Remove unused localhost wrapper functions that were never called:
  - isPortOpen() - wrapper around isPortOpenOnIP with hardcoded 127.0.0.1
  - findAvailablePort() - wrapper around findAvailablePortOnIP with hardcoded 127.0.0.1
  - ensurePortAvailable() - wrapper around ensurePortAvailableOnIP with hardcoded 127.0.0.1
  - ensureAllPortsAvailable() - wrapper around ensureAllPortsAvailableOnIP with hardcoded 127.0.0.1

  Since this is new functionality with no backwards compatibility concerns,
  these wrapper functions were not needed. The comments claiming they were
  'kept for future use or backwards compatibility' are no longer valid.

- Update documentation to reference GrpcPortOffset constant instead of hardcoded 10000:
  - Update comment in ensureAllPortsAvailableOnIP to use GrpcPortOffset
  - Update admin.port.grpc flag help text to reference GrpcPortOffset

Note: getBindIp() is actually being used and should be retained (contrary to
the review comment suggesting it was unused - it's called in both runMini
and startMiniServices functions)

* refactor: prevent HTTP/gRPC port collisions and improve error handling

- Add upfront reservation of all calculated gRPC ports before allocating HTTP ports
  to prevent collisions where an HTTP port allocation could use a port that will
  later be needed for a gRPC port calculation.

  Example scenario that is now prevented:
  - Master HTTP reallocated from 9333 to 9334 (original in use)
  - Filer HTTP search finds 19334 available and assigns it
  - Master gRPC calculated as 9334 + GrpcPortOffset = 19334 → collision!

  Now: reserved gRPC ports are tracked upfront and HTTP port search skips them.

- Improve admin server gRPC port fallback error handling:
  - Change from silent V(1) verbose log to Warningf to make the error visible
  - Update comment to clarify this indicates a problem in the port initialization sequence
  - Add explanation that the fallback calculation may cause bind failure

- Update ensureAllPortsAvailableOnIP comment to clarify it avoids reserved ports

* fix: enforce reserved ports in HTTP allocation and improve admin gRPC fallback

Critical fixes for port allocation safety:

1. Make findAvailablePortOnIP and ensurePortAvailableOnIP aware of reservedPorts:
   - Add reservedPorts map parameter to both functions
   - findAvailablePortOnIP now skips reserved ports when searching for alternatives
   - ensurePortAvailableOnIP passes reservedPorts through to findAvailablePortOnIP
   - This prevents HTTP ports from being allocated to ports reserved for gRPC

2. Update ensureAllPortsAvailableOnIP to pass reservedPorts:
   - Pass the reservedPorts map to ensurePortAvailableOnIP calls
   - Maintains the map updates (delete/add) for accuracy as ports change

3. Replace blind admin gRPC port fallback with proper availability checks:
   - Previous code just calculated *miniAdminOptions.port + GrpcPortOffset
   - New code checks both the calculated port and finds alternatives if needed
   - Uses the same availability checking logic as initializeGrpcPortsOnIP
   - Properly logs the fallback process and any port changes
   - Will fail gracefully if no available ports found (consistent with other services)

These changes eliminate two critical vulnerabilities:
- HTTP port allocation can no longer accidentally claim gRPC ports
- Admin gRPC port fallback no longer blindly uses an unchecked port

* fix: prevent gRPC port collisions during multi-service fallback allocation

Critical fix for gRPC port allocation safety across multiple services:

Problem: When multiple services need gRPC port fallback allocation in sequence
(e.g., Master gRPC unavailable → finds alternative, then Filer gRPC unavailable
→ searches from calculated port), there was no tracking of previously allocated
gRPC ports. This could allow two services to claim the same port.

Scenario that is now prevented:
- Master gRPC: calculated 19333 unavailable → finds 19334 → assigns 19334
- Filer gRPC: calculated 18888 unavailable → searches from 18889, might land on
  19334 if consecutive ports in range are unavailable (especially with custom
  port configurations or in high-port-contention environments)

Solution:
- Add allocatedGrpcPorts map to track gRPC ports allocated within the function
- Check allocatedGrpcPorts before using calculated port for each service
- Pass allocatedGrpcPorts to findAvailablePortOnIP when finding fallback ports
- Add allocatedGrpcPorts[port] = true after each successful allocation
- This ensures no two services can allocate the same gRPC port

The fix handles both:
1. Calculated gRPC ports (when grpcPort == 0)
2. Explicitly set gRPC ports (when user provides -service.port.grpc value)

While default port spacing makes collision unlikely, this fix is essential for:
- Custom port configurations
- High-contention environments
- Edge cases with many unavailable consecutive ports
- Correctness and safety guarantees

* feat: enforce hard-fail behavior for explicitly specified ports

When users explicitly specify a port via command-line flags (e.g., -s3.port=8333),
the server should fail immediately if the port is unavailable, rather than silently
falling back to an alternative port. This prevents user confusion and makes misconfiguration
failures obvious.

Changes:
- Modified ensurePortAvailableOnIP() to check if a port was explicitly passed via isFlagPassed()
- If an explicit port is unavailable, return error instead of silently allocating alternative
- Updated ensureAllPortsAvailableOnIP() to handle the returned error and fail startup
- Modified runMini() to check error from ensureAllPortsAvailableOnIP() and return false on failure
- Default ports (not explicitly specified) continue to fallback to available alternatives

This ensures:
- Explicit ports: fail if unavailable (e.g., -s3.port=8333 fails if 8333 is taken)
- Default ports: fallback to alternatives (e.g., s3.port without flag falls back to 8334 if 8333 taken)

* fix: accurate error messages for explicitly specified unavailable ports

When a port is explicitly specified via CLI flags but is unavailable, the error message
now correctly reports the originally requested port instead of reporting a fallback port
that was calculated internally.

The issue was that the config file applied after CLI flag parsing caused isFlagPassed()
to return true for ports loaded from the config file (since flag.Visit() was called during
config file application), incorrectly marking them as explicitly specified.

Solution: Capture which port flags were explicitly passed on the CLI BEFORE the config file
is applied, storing them in the explicitPortFlags map. This preserves the accurate
distinction between user-specified ports and defaults/config-file ports.

Example:
- User runs: weed mini -dir=. -s3.port=22
- Now correctly shows: 'port 22 for S3 (specified by flag s3.port) is not available'
- Previously incorrectly showed: 'port 8334 for S3...' (some calculated fallback)

* fix: respect explicitly specified ports and prevent config file override

When a port is explicitly specified via CLI flags (e.g., -s3.port=8333),
the config file options should NOT override it. Previously, config file
options would be applied if the flag value differed from default, but
this check wasn't sufficient to prevent override in all cases.

Solution: Check the explicitPortFlags map before applying any config file
port options. If a port was explicitly passed on the CLI, skip applying
the config file option for that port.

This ensures:
- Explicit ports take absolute precedence over config file ports
- Config file ports are only used if port wasn't specified on CLI
- Example: 'weed mini -s3.port=8333' will use 8333, never the config file value

* fix: don't print usage on port allocation error

When a port allocation fails (e.g., explicit port is unavailable), exit
immediately without showing the usage example. This provides cleaner
error output when the error is expected (port conflict).

* refactor: clean up code quality issues

Remove no-op assignment (calculatedPort = calculatedPort) that had no effect.
The variable already holds the correct value when no alternative port is
found.

Improve documentation for the defensive gRPC port initialization fallback
in startAdminServer. While this code shouldn't execute in normal flow
because ensureAllPortsAvailableOnIP is called earlier in runMini, the
fallback handles edge cases where port initialization may have been skipped
or failed silently due to configuration changes or error handling paths.

* fix: improve worker reconnection robustness and prevent handleOutgoing hang

- Add dedicated streamFailed signaling channel to abort registration waits early when stream dies
- Add per-connection regWait channel to route RegistrationResponse separately from shared incoming channel, avoiding race where other consumers steal the response
- Refactor handleOutgoing() loop to use select on streamExit/errCh, ensuring old handlers exit cleanly on reconnect (prevents stale senders competing with new stream)
- Buffer msgCh to reduce shutdown edge cases
- Add cleanup of streamFailed and regWait channels on reconnect/disconnect
- Fixes registration timeout and potential stream lifecycle hangs on aggressive server max_age recycling

* fix: prevent deadlock when stream error occurs - make cmds send non-blocking

If managerLoop is blocked (e.g., waiting on regWait), a blocking send to cmds
will deadlock handleIncoming. Make the send non-blocking to prevent this.

* fix: address code review comments on mini.go port allocation

- Remove flawed fallback gRPC port initialization and convert to fatal error
  (ensures port initialization issues are caught immediately instead of silently
  failing with an empty reserved ports map)
- Extract common port validation logic to eliminate duplication between
  calculated and explicitly set gRPC port handling

* Fix critical race condition and improve error handling in worker client

- Capture channel pointers before checking for nil (prevents TOCTOU race with reconnect)
- Use async fallback goroutine for cmds send to prevent error loss when manager is busy
- Consistently close regWait channel on disconnect (matches streamFailed behavior)
- Complete cleanup of channels on failed registration
- Improve error messages for clarity (replace 'timeout' with 'failed' where appropriate)

* Add debug logging for registration response routing

Add glog.V(3) and glog.V(2) logs to track successful and dropped registration
responses in handleIncoming, helping diagnose registration issues in production.

* Update weed/worker/client.go

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Ensure stream errors are never lost by using async fallback

When handleIncoming detects a stream error, queue ActionStreamError to managerLoop
with non-blocking send. If managerLoop is busy and cmds channel is full, spawn an
async goroutine to queue the error asynchronously. This ensures the manager is
always notified of stream failures, preventing the connection from remaining in an
inconsistent state (connected=true while stream is dead).

* Refactor handleOutgoing to eliminate duplicate error handling code

Extract error handling and cleanup logic into helper functions to avoid duplication
in nested select statements. This improves maintainability and reduces the risk of
inconsistencies when updating error handling logic.

* Prevent goroutine leaks by adding timeouts to blocking cmds sends

Add 2-second timeouts to both handleStreamError and the async fallback goroutine
when sending ActionStreamError to cmds channel. This prevents the handleOutgoing
and handleIncoming goroutines from blocking indefinitely if the managerLoop is
no longer receiving (e.g., during shutdown), preventing resource leaks.

* Properly close regWait channel in reconnect to prevent resource leaks

Close the regWait channel before setting it to nil in reconnect(), matching the
pattern used in handleDisconnect(). This ensures any goroutines waiting on this
channel during reconnection are properly signaled, preventing them from hanging.

* Use non-blocking async pattern in handleOutgoing error reporting

Refactor handleStreamError to use non-blocking send with async fallback goroutine,
matching the pattern used in handleIncoming. This allows handleOutgoing to exit
immediately when errors occur rather than blocking for up to 2 seconds, improving
responsiveness and consistency across handlers.

* fix: drain regWait channel before closing to prevent message loss

- Add drain loop before closing regWait in reconnect() cleanup
- Add drain loop before closing regWait in handleDisconnect() cleanup
- Ensures no pending RegistrationResponse messages are lost during channel closure

* docs: add comments explaining regWait buffered channel design

- Document that regWait buffer size 1 prevents race conditions
- Explain non-blocking send pattern between sendRegistration and handleIncoming
- Clarify timing of registration response handling in handleIncoming

* fix: improve error messages and channel handling in sendRegistration

- Clarify error message when stream fails before registration sent
- Use two-value receive form to properly detect closed channels
- Better distinguish between closed channel and nil value scenarios

* refactor: extract drain and close channel logic into helper function

- Create drainAndCloseRegWaitChannel() helper to eliminate code duplication
- Replace 3 copies of drain-and-close logic with single function call
- Improves maintainability and consistency across cleanup paths

1d0361d936 Fix: Eliminate duplicate versioned objects in S3 list operations (#7850)
* Fix: Eliminate duplicate versioned objects in S3 list operations

- Move versioned directory processing outside of pagination loop to process only once
- Add deduplication during .versions directory collection phase
- Fix directory handling to not add directories to results in recursive mode
- Directly add versioned entries to contents array instead of using callback

Fixes issue where AWS S3 list operations returned duplicated versioned objects
(e.g., 1000 duplicate entries from 4 unique objects). Now correctly returns only
the unique logical entries without duplication.

Verified with:
  aws s3api list-objects --endpoint-url http://localhost:8333 --bucket pm-itatiaiucu-01
Returns exactly 4 entries (ClientInfo.xml and Repository from 2 Veeam backup folders)

* Refactor: Process .versions directories immediately when encountered

Instead of collecting .versions directories and processing them after the
pagination loop, process them immediately when encountered during traversal.

Benefits:
- Simpler code: removed versionedDirEntry struct and collection array
- More efficient: no need to store and iterate through collected entries
- Same O(V) complexity but with less memory overhead
- Clearer logic: processing happens in one pass during traversal

Since each .versions directory is only visited once during recursive
traversal (we never traverse into them), there's no need for deferred
processing or deduplication.

* Add comprehensive tests for versioned objects list

- TestListObjectsWithVersionedObjects: Tests listing with various delimiters
- TestVersionedObjectsNoDuplication: Core test validating no 250x duplication
- TestVersionedObjectsWithDeleteMarker: Tests delete marker filtering
- TestVersionedObjectsMaxKeys: Tests pagination with versioned objects
- TestVersionsDirectoryNotTraversed: Ensures .versions never traversed
- Fix existing test signature to match updated doListFilerEntries

* style: Fix formatting alignment in versioned objects tests

* perf: Optimize path extraction using string indexing

Replace multiple strings.Split/Join calls with efficient strings.Index
slicing to extract bucket-relative path from directory string.

Reduces unnecessary allocations and improves performance in versioned
objects listing path construction.

* refactor: Address code review feedback from Gemini Code Assist

1. Fix misleading comment about versioned directory processing location.
   Versioned directories are processed immediately in doListFilerEntries,
   not deferred to ListObjectsV1Handler.

2. Simplify path extraction logic using explicit bucket path construction
   instead of index-based string slicing for better readability and
   maintainability.

3. Add clarifying comment to test callback explaining why production logic
   is duplicated - necessary because listFilerEntries is not easily testable
   with filer client injection.

* fmt

* refactor: Address code review feedback from Copilot

- Fix misleading comment about versioned directory processing location
  (note that processing happens within doListFilerEntries, not at top level)
- Add maxKeys validation checks in all test callbacks for consistency
- Add maxKeys check before calling eachEntryFn for versioned objects
- Improve test documentation to clarify testing approach and avoid apologetic tone

* refactor: Address code review feedback from Gemini Code Assist

- Remove redundant maxKeys check before eachEntryFn call on line 541
  (the loop already checks maxKeys <= 0 at line 502, ensuring quota exists)
- Fix pagination pattern consistency in all test callbacks
  - TestVersionedObjectsNoDuplication: Use cursor.maxKeys <= 0 check and decrement
  - TestVersionedObjectsWithDeleteMarker: Use cursor.maxKeys <= 0 check and decrement
  - TestVersionsDirectoryNotTraversed: Use cursor.maxKeys <= 0 check and decrement
- Ensures consistent pagination logic across all callbacks matching production behavior

* refactor: Address code review suggestions for code quality

- Adjust log verbosity from V(5) to V(4) for file additions to reduce noise
  while maintaining useful debug output during troubleshooting
- Remove unused isRecursive parameter from doListFilerEntries function
  signature and all call sites (not used for any logic decisions)
- Consolidate redundant comments about versioned directory handling
  to reduce documentation duplication

These changes improve code maintainability and clarity.

* fmt

* refactor: Add pagination test and optimize stream processing

- Add comprehensive test validation to TestVersionedObjectsMaxKeys
  that verifies truncation is correctly set when maxKeys is exhausted
  with more entries available, ensuring proper pagination state

- Optimize stream processing in doListFilerEntries by using 'break'
  instead of 'continue' when quota is exhausted (cursor.maxKeys <= 0)
  This avoids receiving and discarding entries from the stream when
  we've already reached the requested limit, improving efficiency

cc2edfaf68 fix: enable RetryForever for active-active cluster sync to prevent out-of-sync (#7840)
Fixes #7230

When a cluster goes down during file replication, the chunk upload process
would fail after a limited number of retries. Once the remote cluster came
back online, those failed uploads were never retried, leaving the clusters
out-of-sync.

This change enables the RetryForever flag in the UploadOption when
replicating chunks between filers. This ensures that upload operations
will keep retrying indefinitely, and once the remote cluster comes back
online, the pending uploads will automatically succeed.

Users no longer need to manually run fs.meta.save and fs.meta.load as
a workaround for out-of-sync clusters.

9a4f32fc49 feat: add automatic port detection and fallback for mini command (#7836)
* feat: add automatic port detection and fallback for mini command

- Added port availability detection using TCP binding tests
- Implemented port fallback mechanism searching for available ports
- Support for both HTTP and gRPC port handling
- IP-aware port checking using actual service bind address
- Dual-interface verification (specific IP and wildcard 0.0.0.0)
- All services (Master, Volume, Filer, S3, WebDAV, Admin) auto-reallocate to available ports
- Enables multiple mini instances to run simultaneously without conflicts

* fix: use actual bind IP for service health checks

- Previously health checks were hardcoded to localhost (127.0.0.1)
- This caused failures when services bind to actual IP (e.g., 10.21.153.8)
- Now health checks use the same IP that services are binding to
- Fixes Volume and other service health check failures on non-localhost IPs

* refactor: improve port detection logic and remove gRPC handling duplication

- findAvailablePortOnIP now returns 0 on failure instead of unavailable port
  Allows callers to detect when port finding fails and handle appropriately

- Remove duplicate gRPC port handling from ensureAllPortsAvailableOnIP
  All gRPC port logic is now centralized in initializeGrpcPortsOnIP

- Log final port configuration only after all ports are finalized
  Both HTTP and gRPC ports are now correctly initialized before logging

- Add error logging when port allocation fails
  Makes debugging easier when ports can't be found

* refactor: fix race condition and clean up port detection code

- Convert parallel HTTP port checks to sequential to prevent race conditions
  where multiple goroutines could allocate the same available port
- Remove unused 'sync' import since WaitGroup is no longer used
- Add documentation to localhost wrapper functions explaining they are
  kept for backwards compatibility and future use
- All gRPC port logic is now exclusively handled in initializeGrpcPortsOnIP
  eliminating any duplication in ensureAllPortsAvailableOnIP

* refactor: address code review comments - constants, helper function, and cleanup

- Define GrpcPortOffset constant (10000) to replace magic numbers throughout
  the code for better maintainability and consistency
- Extract bindIp determination logic into getBindIp() helper function
  to eliminate code duplication between runMini and startMiniServices
- Remove redundant 'calculatedPort = calculatedPort' assignment that had no effect
- Update all gRPC port calculations to use GrpcPortOffset constant
  (lines 489, 886 and the error logging at line 501)

* refactor: remove unused wrapper functions and update documentation

- Remove unused localhost wrapper functions that were never called:
  - isPortOpen() - wrapper around isPortOpenOnIP with hardcoded 127.0.0.1
  - findAvailablePort() - wrapper around findAvailablePortOnIP with hardcoded 127.0.0.1
  - ensurePortAvailable() - wrapper around ensurePortAvailableOnIP with hardcoded 127.0.0.1
  - ensureAllPortsAvailable() - wrapper around ensureAllPortsAvailableOnIP with hardcoded 127.0.0.1

  Since this is new functionality with no backwards compatibility concerns,
  these wrapper functions were not needed. The comments claiming they were
  'kept for future use or backwards compatibility' are no longer valid.

- Update documentation to reference GrpcPortOffset constant instead of hardcoded 10000:
  - Update comment in ensureAllPortsAvailableOnIP to use GrpcPortOffset
  - Update admin.port.grpc flag help text to reference GrpcPortOffset

Note: getBindIp() is actually being used and should be retained (contrary to
the review comment suggesting it was unused - it's called in both runMini
and startMiniServices functions)

* refactor: prevent HTTP/gRPC port collisions and improve error handling

- Add upfront reservation of all calculated gRPC ports before allocating HTTP ports
  to prevent collisions where an HTTP port allocation could use a port that will
  later be needed for a gRPC port calculation.

  Example scenario that is now prevented:
  - Master HTTP reallocated from 9333 to 9334 (original in use)
  - Filer HTTP search finds 19334 available and assigns it
  - Master gRPC calculated as 9334 + GrpcPortOffset = 19334 → collision!

  Now: reserved gRPC ports are tracked upfront and HTTP port search skips them.

- Improve admin server gRPC port fallback error handling:
  - Change from silent V(1) verbose log to Warningf to make the error visible
  - Update comment to clarify this indicates a problem in the port initialization sequence
  - Add explanation that the fallback calculation may cause bind failure

- Update ensureAllPortsAvailableOnIP comment to clarify it avoids reserved ports

* fix: enforce reserved ports in HTTP allocation and improve admin gRPC fallback

Critical fixes for port allocation safety:

1. Make findAvailablePortOnIP and ensurePortAvailableOnIP aware of reservedPorts:
   - Add reservedPorts map parameter to both functions
   - findAvailablePortOnIP now skips reserved ports when searching for alternatives
   - ensurePortAvailableOnIP passes reservedPorts through to findAvailablePortOnIP
   - This prevents HTTP ports from being allocated to ports reserved for gRPC

2. Update ensureAllPortsAvailableOnIP to pass reservedPorts:
   - Pass the reservedPorts map to ensurePortAvailableOnIP calls
   - Maintains the map updates (delete/add) for accuracy as ports change

3. Replace blind admin gRPC port fallback with proper availability checks:
   - Previous code just calculated *miniAdminOptions.port + GrpcPortOffset
   - New code checks both the calculated port and finds alternatives if needed
   - Uses the same availability checking logic as initializeGrpcPortsOnIP
   - Properly logs the fallback process and any port changes
   - Will fail gracefully if no available ports found (consistent with other services)

These changes eliminate two critical vulnerabilities:
- HTTP port allocation can no longer accidentally claim gRPC ports
- Admin gRPC port fallback no longer blindly uses an unchecked port

* fix: prevent gRPC port collisions during multi-service fallback allocation

Critical fix for gRPC port allocation safety across multiple services:

Problem: When multiple services need gRPC port fallback allocation in sequence
(e.g., Master gRPC unavailable → finds alternative, then Filer gRPC unavailable
→ searches from calculated port), there was no tracking of previously allocated
gRPC ports. This could allow two services to claim the same port.

Scenario that is now prevented:
- Master gRPC: calculated 19333 unavailable → finds 19334 → assigns 19334
- Filer gRPC: calculated 18888 unavailable → searches from 18889, might land on
  19334 if consecutive ports in range are unavailable (especially with custom
  port configurations or in high-port-contention environments)

Solution:
- Add allocatedGrpcPorts map to track gRPC ports allocated within the function
- Check allocatedGrpcPorts before using calculated port for each service
- Pass allocatedGrpcPorts to findAvailablePortOnIP when finding fallback ports
- Add allocatedGrpcPorts[port] = true after each successful allocation
- This ensures no two services can allocate the same gRPC port

The fix handles both:
1. Calculated gRPC ports (when grpcPort == 0)
2. Explicitly set gRPC ports (when user provides -service.port.grpc value)

While default port spacing makes collision unlikely, this fix is essential for:
- Custom port configurations
- High-contention environments
- Edge cases with many unavailable consecutive ports
- Correctness and safety guarantees

* feat: enforce hard-fail behavior for explicitly specified ports

When users explicitly specify a port via command-line flags (e.g., -s3.port=8333),
the server should fail immediately if the port is unavailable, rather than silently
falling back to an alternative port. This prevents user confusion and makes misconfiguration
failures obvious.

Changes:
- Modified ensurePortAvailableOnIP() to check if a port was explicitly passed via isFlagPassed()
- If an explicit port is unavailable, return error instead of silently allocating alternative
- Updated ensureAllPortsAvailableOnIP() to handle the returned error and fail startup
- Modified runMini() to check error from ensureAllPortsAvailableOnIP() and return false on failure
- Default ports (not explicitly specified) continue to fallback to available alternatives

This ensures:
- Explicit ports: fail if unavailable (e.g., -s3.port=8333 fails if 8333 is taken)
- Default ports: fallback to alternatives (e.g., s3.port without flag falls back to 8334 if 8333 taken)

* fix: accurate error messages for explicitly specified unavailable ports

When a port is explicitly specified via CLI flags but is unavailable, the error message
now correctly reports the originally requested port instead of reporting a fallback port
that was calculated internally.

The issue was that the config file applied after CLI flag parsing caused isFlagPassed()
to return true for ports loaded from the config file (since flag.Visit() was called during
config file application), incorrectly marking them as explicitly specified.

Solution: Capture which port flags were explicitly passed on the CLI BEFORE the config file
is applied, storing them in the explicitPortFlags map. This preserves the accurate
distinction between user-specified ports and defaults/config-file ports.

Example:
- User runs: weed mini -dir=. -s3.port=22
- Now correctly shows: 'port 22 for S3 (specified by flag s3.port) is not available'
- Previously incorrectly showed: 'port 8334 for S3...' (some calculated fallback)

* fix: respect explicitly specified ports and prevent config file override

When a port is explicitly specified via CLI flags (e.g., -s3.port=8333),
the config file options should NOT override it. Previously, config file
options would be applied if the flag value differed from default, but
this check wasn't sufficient to prevent override in all cases.

Solution: Check the explicitPortFlags map before applying any config file
port options. If a port was explicitly passed on the CLI, skip applying
the config file option for that port.

This ensures:
- Explicit ports take absolute precedence over config file ports
- Config file ports are only used if port wasn't specified on CLI
- Example: 'weed mini -s3.port=8333' will use 8333, never the config file value

* fix: don't print usage on port allocation error

When a port allocation fails (e.g., explicit port is unavailable), exit
immediately without showing the usage example. This provides cleaner
error output when the error is expected (port conflict).

* fix: increase worker registration timeout for reconnections

Increase the worker registration timeout from 10 seconds to 30 seconds.
The 10-second timeout was too aggressive for reconnections when the admin
server might be busy processing other operations. Reconnecting workers need
more time to:
1. Re-establish the gRPC connection
2. Send the registration message
3. Wait for the admin server to process and respond

This prevents spurious "registration timeout" errors during long-running
mini instances when brief network hiccups or admin server load cause delays.

* refactor: clean up code quality issues

Remove no-op assignment (calculatedPort = calculatedPort) that had no effect.
The variable already holds the correct value when no alternative port is
found.

Improve documentation for the defensive gRPC port initialization fallback
in startAdminServer. While this code shouldn't execute in normal flow
because ensureAllPortsAvailableOnIP is called earlier in runMini, the
fallback handles edge cases where port initialization may have been skipped
or failed silently due to configuration changes or error handling paths.

* fix: prevent panic on close of closed channel in worker client reconnection

- Use idiomatic Go pattern of setting channels to nil after closing instead of flags
- Extract repeated safe-close logic into safeCloseChannel() helper method
- Call safeCloseChannel() in attemptConnection(), reconnect(), and handleDisconnect()
- In safeCloseChannel(), check if channel is not nil, close it, and set to nil
- Also set streamExit to nil in attemptConnection() when registration fails
- This follows Go best practices for channel management and prevents double-close panics
- Improved code maintainability by eliminating duplication

31cb28d9d3 feat: auto-configure optimal volume size limit based on available disk space (#7833)
* feat: auto-configure optimal volume size limit based on available disk space

- Add calculateOptimalVolumeSizeMB() function with OS-independent disk detection
- Reuses existing stats.NewDiskStatus() which works across Linux, macOS, Windows, BSD, Solaris
- Algorithm: available disk / 100, rounded up to nearest power of 2 (64MB, 128MB, 256MB, 512MB, 1024MB)
- Volume size capped to maximum of 1GB (1024MB) for better stability
- Minimum volume size is 64MB
- Uses efficient bits.Len() for power-of-2 rounding instead of floating-point operations
- Only auto-calculates volume size if user didn't specify a custom value via -master.volumeSizeLimitMB
- Respects user-specified values without override
- Master logs whether value was auto-calculated or user-specified
- Welcome message displays the configured volume size with correct format string ordering
- Removed unused autoVolumeSizeMB variable (logging handles source tracking)

Fixes: #0

* Refactor: Consolidate volume size constants and use robust flag detection for mini mode

This commit addresses all code review feedback on the auto-optimal volume size feature:

1. **Consolidate hardcoded defaults into package-level constants**
   - Moved minVolumeSizeMB=64 and maxVolumeSizeMB=1024 from local function-scope
     constants to package-level constants for consistency and maintainability
   - All three volume size constants (min, default, max) now defined in one place

2. **Implement robust flag detection using flag.Visit()**
   - Added isFlagPassed() helper function using flag.Visit() to check if a CLI
     flag was explicitly passed on the command line
   - Replaces the previous implementation that checked if current value equals
     default (which could incorrectly assume user intent if default was specified)
   - Now correctly detects user override regardless of the actual value

3. **Restructure power-of-2 rounding logic for clarity**
   - Changed from 'only round if above min threshold' to 'always round to power-of-2
     first, then apply min/max constraints'
   - More robust: works correctly even if min/max constants are adjusted in future
   - Clearer intent: all non-zero values go through consistent rounding logic

4. **Fix import ordering**
   - Added 'flag' import (aliased to fla9 package) to support isFlagPassed()
   - Added 'math/bits' import to support power-of-2 rounding

Benefits:
- Better code organization with all volume size limits in package constants
- Correct user override detection that doesn't rely on value equality checks
- More maintainable rounding logic that's easier to understand and modify
- Consistent with SeaweedFS conventions (uses fla9 package like other commands)

* fix: Address code review feedback for volume size calculation

This commit resolves three code review comments for better code quality and robustness:

1. **Handle comma-separated directories in -dir flag**
   - The -dir flag accepts comma-separated list of directories, but the volume size
     calculation was passing the entire string to util.ResolvePath()
   - Now splits on comma and uses the first directory for disk space calculation
   - Added explanatory comment about the multi-directory support
   - Ensures the optimal size calculation works correctly in all scenarios

2. **Change disk detection failure from verbose log to warning**
   - When disk status cannot be determined, the warning is now logged via
     glog.Warningf() instead of glog.V(1).Infof()
   - Makes the event visible in default logs without requiring verbose mode
   - Better alerting for operators about fallback to default values

3. **Avoid recalculating availableMB/100 and define bytesPerMB constant**
   - Added bytesPerMB = 1024*1024 constant for clarity and reusability
   - Replaced hardcoded (1024 * 1024) with bytesPerMB constant
   - Store availableMB/100 in initialOptimalMB variable to avoid recalculation
   - Log message now references initialOptimalMB instead of recalculating
   - Improves maintainability and reduces redundant computation

All three changes maintain the same logic while improving code quality and
robustness as requested by the reviewer.

* fix: Address rounding logic, logging clarity, and disk capacity measurement issues

This commit resolves three additional code review comments to improve robustness
and clarity of the volume size calculation:

1. **Fix power-of-2 rounding logic for edge cases**
   - The previous condition 'if optimalMB > 0' created a bug: when optimalMB=1,
     bits.Len(0)=0, resulting in 1<<0=1, which is below minimum (64MB)
   - Changed to explicitly handle zero case first: 'if optimalMB == 0'
   - Separate zero-handling from power-of-2 rounding ensures correct behavior:
     * optimalMB=0 → set to minVolumeSizeMB (64)
     * optimalMB>=1 → apply power-of-2 rounding
   - Then apply min/max constraints unconditionally
   - More explicit and easier to reason about correctness

2. **Use total disk capacity instead of free space for stable configuration**
   - Changed from diskStatus.Free (available space) to diskStatus.All (total capacity)
   - Free space varies based on current disk usage at startup time
   - This caused inconsistent volume sizes: same disk could get different sizes
     depending on how full it is when the service starts
   - Using total capacity ensures predictable, stable configuration across restarts
   - Better aligns with the intended behavior of sizing based on disk capacity
   - Added explanatory comments about why total capacity is more appropriate

3. **Improve log message clarity and accuracy**
   - Updated message to clearly show:
     * 'total disk capacity' instead of vague 'available disk'
     * 'capacity/100 before rounding' to match actual calculation
     * 'clamped to [min,max]' instead of 'capped to max' to show both bounds
     * Includes min and max values in log for context
   - More accurate and helpful for operators troubleshooting volume sizing

These changes ensure the volume size calculation is both correct and predictable.

* feat: Save mini configuration to file for persistence and documentation

This commit adds persistent configuration storage for the 'weed mini' command,
saving all non-default parameters to a JSON configuration file for:

1. **Configuration Documentation**
   - All parameters actually passed on the command line are saved
   - Provides a clear record of the running configuration
   - Useful for auditing and understanding how the system is configured

2. **Persistence of Auto-Calculated Values**
   - The auto-calculated optimal volume size (master.volumeSizeLimitMB) is saved
     with a note indicating it was auto-calculated
   - On restart, if the auto-calculated value exists, it won't be recalculated
   - Users can delete the auto-calculated entry to force recalculation on next startup
   - Provides stable, predictable configuration across restarts

3. **Configuration File Location**
   - Saved to: <data-folder>/.seaweedfs/mini.config.json
   - Uses the first directory from comma-separated -dir list
   - Directory is created automatically if it doesn't exist
   - JSON format for easy parsing and manual editing

4. **Implementation Details**
   - Uses flag.Visit() to collect only explicitly passed flags
   - Distinguishes between user-specified and auto-calculated values
   - Includes helpful notes in the JSON file
   - Graceful handling of save errors (logs warnings, doesn't fail startup)

The configuration file includes all parameters such as:
- IP and port settings (master, filer, volume, admin)
- Data directories and metadata folders
- Replication and collection settings
- S3 and IAM configurations
- Performance tuning parameters (concurrency limits, timeouts, etc.)
- Auto-calculated volume size (if applicable)

Example mini.config.json output:
{
  "debug": "true",
  "dir": "/data/seaweedfs",
  "master.port": "9333",
  "filer.port": "8888",
  "volume.port": "9340",
  "master.volumeSizeLimitMB.auto": "256",
  "_note_auto_calculated": "This value was auto-calculated. Remove it to recalculate on next startup."
}

This allows operators to:
- Review what configuration was active
- Replicate the configuration on other systems
- Understand the startup behavior
- Control when auto-calculation occurs

* refactor: Change configuration file format to match command-line options format

Update the saved configuration format from JSON to shell-compatible options format
that matches how options are expected to be passed on the command line.

Configuration file: .seaweedfs/mini.options

Format: Each line contains a command-line option in the format -name=value

Benefits:
- Format is compatible with shell scripts and can be sourced
- Can be easily converted to command-line options
- Human-readable and editable
- Values with spaces are properly quoted
- Includes helpful comments explaining auto-calculated values
- Directly usable with weed mini command

The file can be used in multiple ways:
1. Extract options: cat .seaweedfs/mini.options | grep -v '^#' | tr '\n' ' '
2. Inline in command: weed mini \$(cat .seaweedfs/mini.options | grep -v '^#')
3. Manual review: cat .seaweedfs/mini.options

* refactor: Save mini.options directly to -dir folder

* docs: Update PR description with accurate algorithm and examples

Update the function documentation comments to accurately reflect the implemented
algorithm and provide real-world examples with actual calculated outputs.

Changes:
- Clarify that algorithm uses total disk capacity (not free space)
- Document exact calculation: capacity/100, round to power of 2, clamp to [64,1024]
- Add realistic examples showing input disk sizes and resulting volume sizes:
  * 10GB disk → 64MB (minimum)
  * 100GB disk → 64MB (minimum)
  * 1TB disk → 64MB (minimum)
  * 6.4TB disk → 64MB
  * 12.8TB disk → 128MB
  * 100TB disk → 1024MB (maximum)
  * 1PB disk → 1024MB (maximum)
- Include note that values are rounded to next power of 2 and capped at 1GB

This helps users understand the volume size calculation and predict what size
will be set for their specific disk configurations.

* feat: integrate configuration file loading into mini startup

- Load mini.options file at startup if it exists
- Apply loaded configuration options before normal initialization
- CLI flags override file-based configuration
- Exclude 'dir' option from being saved (environment-specific)
- Configuration file format: option=value without leading dashes
- Auto-calculated volume size persists with recalculation marker

3613279f25 Add 'weed mini' command for S3 beginners and small/dev use cases (#7831)
* Add 'weed mini' command for S3 beginners and small/dev use cases

This new command simplifies starting SeaweedFS by combining all components
in one process with optimized settings for development and small deployments.

Features:
- Starts master, volume, filer, S3, WebDAV, and admin in one command
- Volume size limit: 64MB (optimized for small files)
- Volume max: 0 (auto-configured based on free disk space)
- Pre-stop seconds: 1 (faster shutdown for development)
- Master peers: none (single master mode by default)
- Includes admin UI with one worker for maintenance tasks
- Clean, user-friendly startup message with all endpoint URLs

Usage:
  weed mini                    # Use default temp directory
  weed mini -dir=/data        # Custom data directory

This makes it much easier for:
- Developers getting started with SeaweedFS
- Testing and development workflows
- Learning S3 API with SeaweedFS
- Small deployments that don't need complex clustering

* Change default volume server port to 9340 to avoid popular port 8080

* Fix nil pointer dereference by initializing all required volume server fields

Added missing VolumeServerOptions field initializations:
- id, publicUrl, diskType
- maintenanceMBPerSecond, ldbTimeout
- concurrentUploadLimitMB, concurrentDownloadLimitMB
- pprof, idxFolder
- inflightUploadDataTimeout, inflightDownloadDataTimeout
- hasSlowRead, readBufferSizeMB

This resolves the panic that occurred when starting the volume server.

* Fix multiple nil pointer dereferences in mini command

Added missing field initializations for:
- Master options: raftHashicorp, raftBootstrap, telemetryUrl, telemetryEnabled
- Filer options: filerGroup, saveToFilerLimit, concurrentUploadLimitMB,
  concurrentFileUploadLimit, localSocket, showUIDirectoryDelete,
  downloadMaxMBps, diskType, allowedOrigins, exposeDirectoryData, tusBasePath
- Volume options: id, publicUrl, diskType, maintenanceMBPerSecond, ldbTimeout,
  concurrentUploadLimitMB, concurrentDownloadLimitMB, pprof, idxFolder,
  inflightUploadDataTimeout, inflightDownloadDataTimeout, hasSlowRead, readBufferSizeMB
- WebDAV options: tlsPrivateKey, tlsCertificate, filerRootPath
- Admin options: master

These initializations are required to avoid runtime panics when starting components.

* Fix remaining S3 option nil pointers in mini command

* Update mini command: 256MB volume size and add S3 access instructions for beginners

* mini: set default master.volumeSizeLimitMB to 128MB and update help/banner text

* mini: shorten S3 help text to a concise pointer to docs/Admin UI

* mini: remove duplicated component bullet list, use concise sentence

* mini: tidy help alignment and update example usage

* mini: default -dir to current directory

* mini: load initial S3 credentials from env and write IAM config

* mini: use AWS env vars for initial S3 creds; instruct to create via Admin UI if absent

* Improve startup synchronization with channel-based coordination

- Replace fragile time.Sleep delays with robust channel-based synchronization
- Implement proper service dependency ordering (Master → Volume → Filer → S3/WebDAV/Admin)
- Add sync.WaitGroup for goroutine coordination
- Add startup readiness logging for better visibility
- Implement 10-second timeout for admin server startup
- Remove arbitrary sleep delays for faster, more reliable startup
- Services now start deterministically based on dependencies, not timing

This makes the startup process more reliable and eliminates race conditions on slow systems or under load.

* Refactor service startup logic for better maintainability

Extract service startup into dedicated helper functions:
- startMiniServices(): Orchestrates all service startup with dependency coordination
- startServiceWithCoordination(): Starts services with readiness signaling
- startServiceWithoutReady(): Starts services without readiness signaling
- startS3Service(): Encapsulates S3 initialization logic

Benefits:
- Reduced code duplication in runMini()
- Clearer separation of concerns
- Easier to add new services or modify startup sequence
- More testable code structure
- Improved readability with explicit service names and logging

* Remove unused serviceStartupInfo struct type

- Delete the serviceStartupInfo struct that was defined but never used
- Improves code clarity by removing dead code
- All service startup is now handled directly by helper functions

* Preserve existing IAM config file instead of truncating

- Use os.Stat to check if IAM config file already exists
- Only create and write configuration if file doesn't exist
- Log appropriate messages for each case:
  * File exists: skip writing, preserve existing config
  * File absent: create with os.OpenFile and write new config
  * Stat error: log error without overwriting
- Set *miniIamConfig only when new file is successfully created
- Use os.O_CREATE|os.O_WRONLY flags for safe file creation
- Handles file operations with proper error checking and cleanup

* Fix CodeQL security issue: prevent logging of sensitive S3 credentials

- Add createdInitialIAM flag to track when initial IAM config is created from env vars
- Set flag in startS3Service() when new IAM config is successfully written
- Update welcome message to inform user of credential creation without exposing secrets
- Print only the username (mini) and config file location to user
- Never print access keys or secret keys in clear text
- Maintain security while keeping user informed of what was created
- Addresses CodeQL finding: Clear-text logging of sensitive information

* Fix three code review issues in weed mini command

1. Fix deadlock in service startup coordination:
   - Run blocking service functions (startMaster, startFiler, etc.) in separate goroutines
   - This allows readyChan to be closed and prevents indefinite blocking
   - Services now start concurrently instead of sequentially blocking the coordinator

2. Use shared grace.StartDebugServer for consistency:
   - Replace inline debug server startup with grace.StartDebugServer
   - Improves code consistency with other commands (master, filer, etc.)
   - Removes net/http import which is no longer needed

3. Simplify IAM config file cleanup with defer:
   - Use 'defer f.Close()' instead of multiple f.Close() calls
   - Ensures file is closed regardless of which code path is taken
   - Improves robustness and code clarity

* fmt

* Fix: Remove misleading 'service is ready' logs

The previous fix removed 'go' from service function calls but left misleading
'service is ready' log messages. The service helpers now correctly:
- Call fn() directly (blocking) instead of 'go fn()' (non-blocking)
- Remove the 'service is ready' message that was printed before the service
  actually started running
- Services run as blocking goroutines within the coordinator goroutine,
  which keeps them alive while the program runs
- The readiness channels still work correctly because they're closed when
  the coordinator finishes waiting for dependencies

* Update mini.go

* Fix four code review issues in weed mini command

1. Use restrictive file permissions (0600) for IAM config:
   - Changed from 0644 to 0600 when creating iam_config.json
   - Prevents world-readable access to sensitive AWS credentials
   - Protects AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY

2. Remove unused sync.WaitGroup:
   - Removed WaitGroup that was never waited on
   - All services run as blocking goroutines in the coordinator
   - Main goroutine blocks indefinitely with select{}
   - Removes unnecessary complexity without changing behavior

3. Merge service startup helper functions:
   - Combined startServiceWithCoordination and startServiceWithoutReady
   - Made readyChan optional (nil for services without readiness signaling)
   - Reduces code duplication and improves maintainability
   - Both services now use single startServiceWithCoordination function

4. Fix admin server readiness check:
   - Removed misleading timeout channel that never closed at startup
   - Replaced with simple 2-second sleep before worker startup
   - startAdminServer() blocks indefinitely, so channel would only close on shutdown
   - Explicit sleep is clearer about the startup coordination intent

* Fix three code quality issues in weed mini command

1. Define volume configuration as named constants:
   - Added miniVolumeMaxDataVolumeCounts = "0"
   - Added miniVolumeMinFreeSpace = "1"
   - Added miniVolumeMinFreeSpacePercent = "1"
   - Removed local variable assignments in Volume startup
   - Improves maintainability and documents configuration intent

2. Fix deadlock in startServiceWithCoordination:
   - Changed from 'defer close(readyChan)' with blocking fn() to running fn() in goroutine
   - Close readyChan immediately after launching service goroutine
   - Prevents deadlock where fn() never returns, blocking defer execution
   - Allows dependent services to start without waiting for blocking call

3. Improve admin server readiness check:
   - Replaced fixed 2-second sleep with polling the gRPC port
   - Polls up to 20 times (10 seconds total) with 500ms intervals
   - Uses net.DialTimeout to check if port is available
   - Properly handles IPv6 addresses using net.JoinHostPort
   - Logs progress and warnings about connection status
   - More robust than sleep against server startup timing variations

4. Add net import for network operations (IPv6 support)

Also fixed IAM config file close error handling to properly check error
from f.Close() and log any failures, preventing silent data loss on NFS.

* Document environment variable setup for S3 credentials

Updated welcome message to explain two ways to create S3 credentials:

1. Environment variables (recommended for quick setup):
   - Set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
   - Run 'weed mini -dir=/data'
   - Creates initial 'mini' user credentials automatically

2. Admin UI (for managing multiple users and policies):
   - Open http://localhost:23646 (Admin UI)
   - Add identities to create new S3 credentials

This gives users clear guidance on the easiest way to get started with S3
credentials while also explaining the more advanced option for multiple users.

* Print welcome message after all services are running

Moved the welcome message printing from immediately after startMiniServices()
to after all services have been started and are ready. This ensures users see
the welcome message only after startup is complete, not mixed with startup logs.

Changes:
- Extract welcome message logic into printWelcomeMessage() function
- Call printWelcomeMessage() after startMiniServices() completes
- Change message from 'are starting' to 'are running and ready to use'
- This provides cleaner startup output without interleaved logs

* Wait for all services to complete before printing welcome message

The welcome message should only appear after all services are fully running and
the worker is connected. This prevents the message from appearing too early before
startup logs complete.

Changes:
- Pass allServicesReady channel through startMiniServices()
- Add adminReadyChan to track when admin/worker startup completes
- Signal allServicesReady when admin service is fully ready
- Wait for allServicesReady in runMini() before printing welcome message
- This ensures clean output: startup logs first, then welcome message once ready

Now the user sees all startup activity, then a clear welcome message when
everything is truly ready to use.

* Fix welcome message timing: print after worker is fully started

The welcome message was printing too early because allServicesReady was being
closed when the Admin service goroutine started, not when it actually completed.
The Admin service launches startMiniAdminWithWorker() which is a blocking call
that doesn't return until the worker is fully connected.

Now allServicesReady is passed through to startMiniWorker() which closes it
after the worker successfully starts and connects to the admin server.

This ensures the welcome message only appears after:
- Master is ready
- Volume server is ready
- Filer is ready
- S3 service is ready
- WebDAV service is ready
- Admin server is ready
- Worker is connected and running

All startup logs appear first, then the clean welcome message at the end.

* Wait for S3 and WebDAV services to be ready before showing welcome message

The welcome message was printing before S3 and WebDAV servers had fully
initialized. Now the readiness flow is:

1. Master → ready
2. Volume → ready
3. Filer → ready
4. S3 → ready (signals s3ReadyChan)
5. WebDAV → ready (signals webdavReadyChan)
6. Admin/Worker → starts, then waits for both S3 and WebDAV
7. Welcome message prints (all services truly ready)

Changes:
- Add s3ReadyChan and webdavReadyChan to service startup
- Pass S3 and WebDAV ready channels through to Admin service
- Admin/Worker waits for both S3 and WebDAV before closing allServicesReady
- This ensures welcome message appears only when all services are operational

* Admin service should wait for Filer, S3, and WebDAV to be ready

Admin service depends on Filer being operational since it uses the filer
for credential storage. It also makes sense to wait for S3 and WebDAV
since they are user-facing services that should be ready before Admin.

Updated dependencies:
- Admin now waits for: Master, Filer, S3, WebDAV
- This ensures all critical services are operational before Admin starts
- Welcome message will print only after all services including Admin are ready

* Add initialization delay for S3 and WebDAV services

S3 and WebDAV servers need extra time to fully initialize and start listening
after their service functions are launched. Added a 1-second delay after
launching S3 and WebDAV goroutines before signaling readiness.

This ensures the welcome message doesn't print until both services have
emitted their startup logs and are actually serving requests.

* Increase service initialization wait times for more reliable startup

- Increase S3 and WebDAV initialization delay from 1s to 2s to ensure they emit startup logs before welcome message
- Add 1s initialization delay for Filer to ensure it's listening
- Increase admin gRPC polling timeout from 10s to 20s to ensure admin server is fully ready
- This ensures welcome message prints only after all services are fully initialized and ready to accept requests

* Increase service wait time to 10 seconds for reliable startup

All services now wait 10 seconds after launching to ensure they are fully initialized and ready before signaling readiness to dependent services. This ensures the welcome message prints only after all services have fully started.

* Replace fixed 10s delay with intelligent port polling for service readiness

Instead of waiting a fixed 10 seconds for each service, now polls the service
port to check if it's actually accepting connections. This eliminates unnecessary
waiting and allows services to signal readiness as soon as they're ready.

- Polls each service port with up to 30 attempts (6 seconds total)
- Each attempt waits 200ms before retrying
- Stops polling immediately once service is ready
- Falls back gracefully if service is unknown
- Significantly faster startup sequence while maintaining reliability

* Replace channel-based coordination with HTTP pinging for service readiness

Instead of using channels to coordinate service startup, now uses HTTP GET requests
to ping each service endpoint to check if it's ready to accept connections.

Key changes:
- Removed all readiness channels (masterReadyChan, volumeReadyChan, etc.)
- Simplified startMiniServices to use sequential HTTP polling for each service
- startMiniService now just starts the service with logging
- waitForServiceReady uses HTTP client to ping service endpoints (max 6 seconds)
- waitForAdminServerReady uses HTTP GET to check admin server availability
- startMiniAdminWithWorker and startMiniWorker simplified without channel parameters

Benefits:
- Cleaner, more straightforward code
- HTTP pinging is more reliable than TCP port probing
- Services signal readiness through their HTTP endpoints
- Eliminates channel synchronization complexity

* log level

* Remove overly specific comment from volume size limit in welcome message

The '(good for small files)' comment is too limiting. The 128MB volume size
limit works well for general use cases, not just small files. Simplified the
message to just show the value.

* Ensure allServicesReady channel is always closed via defer

Add 'defer close(allServicesReady)' at the start of startMiniAdminWithWorker
to guarantee the channel is closed on ALL exit paths (normal and error).
This prevents the caller waiting on <-allServicesReady from ever hanging,
while removing the explicit close() at the successful end prevents panic
from double-close.

This makes the code more robust by:
- Guaranteeing channel closure even if worker setup fails
- Eliminating the possibility of caller hanging on errors
- Following Go defer patterns for resource cleanup

* Enhance health check polling for more robust service coordination

The service startup already uses HTTP health checks via waitForServiceReady()
to verify services are actually accepting connections. This commit improves
the health check implementation:

Changes:
- Elevated success logging to Info level so users see when services become ready
- Improved error messages to clarify that health check timeouts are not fatal
- Services continue startup even if health checks timeout (they may still work)
- Consistent handling of health check results across all services

This provides better visibility into service startup while maintaining the
existing robust coordination via HTTP pinging rather than just TCP port checks.

* Implement stricter error handling for robust mini server startup

Apply all PR review feedback to ensure the mini server fails fast and clearly
when critical components cannot start:

Changes:
1. Remove redundant miniVolumeMinFreeSpacePercent constant
   - Simplified util.MustParseMinFreeSpace() call to use single parameter

2. Make service readiness checks fatal errors:
   - Master, Volume, Filer, S3, WebDAV health check failures now return errors
   - Prevents partially-functional servers from running
   - Caller can handle errors gracefully instead of continuing with broken state

3. Make admin server readiness fatal:
   - Admin gRPC availability is critical for worker startup
   - Use glog.Fatalf to terminate with clear error message

4. Improve IAM config error handling:
   - Treat all file operation failures (stat, open, write, close) as fatal
   - Prevents silent failures in S3 credential setup
   - User gets immediate feedback instead of authentication issues later

5. Use glog.Fatalf for critical worker setup errors:
   - Failed to create worker directory, task directories, or worker instance
   - Failed to create admin client or start worker
   - Ensures mini server doesn't run in broken state

This ensures deterministic startup: services succeed completely or fail with
clear, actionable error messages for the user.

* Make health checks non-fatal for graceful degradation and improve IAM file handling

Address PR feedback to make the mini command more resilient for development:

1. Make health check failures non-fatal
   - Master, Volume, Filer, S3, WebDAV health checks now log warnings but allow startup
   - Services may still work even if health check endpoints aren't immediately available
   - Aligns with intent of a dev-focused tool that should be forgiving of timing issues
   - Only prevents startup if startup coordination or critical errors occur

2. Improve IAM config file handling
   - Refactored to guarantee file is always closed using separate error variables
   - Opens file once and handles write/close errors independently
   - Maintains strict error handling while improving code clarity
   - All file operation failures still cause fatal errors (as intended)

This makes startup more graceful while maintaining critical error handling for
fundamental failures like missing directories or configuration errors.

- Remove unused adminServerDone channel that was created but never read

* Address code review feedback for robustness and resource management

- Use defer f.Close() for IAM file handling to ensure file is closed in all code paths, preventing potential file descriptor leaks
- Use 127.0.0.1 instead of *miniIp for service readiness checks to ensure checks always target localhost, improving reliability in environments with firewalls or complex network configurations
- Simplify error handling in waitForAdminServerReady by using single error return instead of separate write/close error variables

* Fix function declaration formatting

- Separate closing brace of startS3Service from startMiniAdminWithWorker declaration with blank line
- Move comment to proper position above function declaration
- Run gofmt for consistent formatting

* Fix IAM config pointer assignment when file already exists

- Add missing *miniIamConfig = iamPath assignment when IAM config file already exists
- Ensures S3 service is properly pointed to the existing IAM configuration
- Retains logging to inform user that existing configuration is being preserved

* Improve pointer assignments and worker synchronization

- Simplify grpcPort and dataDir pointer assignments by directly dereferencing and assigning values instead of taking address of local variables
- Replace time.Sleep(500ms) with proper TCP-based polling to wait for worker gRPC port readiness
- Add waitForWorkerReady function that polls worker's gRPC port with max 6-second timeout
- Add net package import for TCP connection checks
- Improves code idiomaticity and synchronization robustness

* Refactor and simplify error handling for maintainability

- Remove unused error return from startMiniServices (always returned nil)
- Update runMini caller to not expect error from startMiniServices
- Refactor init() into component-specific helper functions:
  * initMiniCommonFlags() for common options
  * initMiniMasterFlags() for master server options
  * initMiniFilerFlags() for filer server options
  * initMiniVolumeFlags() for volume server options
  * initMiniS3Flags() for S3 server options
  * initMiniWebDAVFlags() for WebDAV server options
  * initMiniAdminFlags() for admin server options
- Significantly improves code readability and maintainability
- Each component's flags are now in dedicated, focused functions

f67ba35f4a Make lock_manager.RenewInterval configurable in LiveLock (#7830)
* Make lock_manager.RenewInterval configurable in LiveLock

- Add renewInterval field to LiveLock struct
- Modify StartLongLivedLock to accept renewInterval parameter
- Update all call sites to pass lock_manager.RenewInterval
- Default to lock_manager.RenewInterval if zero is passed

* S3 metrics: reduce collection interval to half of bucketSizeMetricsInterval

Since S3 metrics collection is not critical, check more frequently but
only collect when holding the distributed lock. This allows faster
detection of any issues while avoiding overhead on non-leader instances.

* Remove unused lock_manager import from bucket_size_metrics.go

* Refactor: Make lockTTL the primary parameter, derive renewInterval from it

Instead of configurable renew interval, lockTTL is now the input parameter.
The renewal interval is automatically derived as lockTTL / 2, ensuring that
locks are renewed well before expiration.

Changes:
- Replace renewInterval parameter with lockTTL
- Rename LiveLock.renewInterval field to lockTTL
- Calculate renewInterval as lockTTL / 2 inside the goroutine
- Update all call sites to pass lockTTL values
- Simplify sleep logic to use consistent renewInterval for both states

This approach is more intuitive and guarantees safe renewal windows.

* When locked, renew more aggressively to actively keep the lock

When holding the lock, sleep for renewInterval/2 to renew more frequently.
When seeking the lock, sleep for renewInterval to retry with normal frequency.

This ensures we actively maintain lock ownership while being less aggressive
when competing for the lock.

* Simplify: use consistent renewInterval for all lock states

Since renewInterval is already lockTTL / 2, there's no need to differentiate
between locked and unlocked states. Both use the same interval for consistency.

* Adjust sleep intervals for different lock states

- Locked instances sleep for renewInterval (lockTTL/2) to renew the lock
- Unlocked instances sleep for 5*renewInterval (2.5*lockTTL) to retry acquisition less frequently

5b86d33c3c Fix worker reconnection race condition causing context canceled errors (#7825)
* Fix worker reconnection race condition causing context canceled errors

Fixes #7824

This commit fixes critical connection stability issues between admin server
and workers that manifested as rapid reconnection cycles with 'context canceled'
errors, particularly after 24+ hours of operation in containerized environments.

Root Cause:
-----------
Race condition where TWO goroutines were calling stream.Recv() on the same
gRPC bidirectional stream concurrently:

1. sendRegistrationSync() started a goroutine that calls stream.Recv()
2. handleIncoming() also calls stream.Recv() in a loop

Per gRPC specification, only ONE goroutine can call Recv() on a stream at a
time. Concurrent Recv() calls cause undefined behavior, manifesting as
'context canceled' errors and stream corruption.

The race occurred during worker reconnection:
- Sometimes sendRegistrationSync goroutine read the registration response first (success)
- Sometimes handleIncoming read it first, causing sendRegistrationSync to timeout
- This left the stream in an inconsistent state, triggering 'context canceled' error
- The error triggered rapid reconnection attempts, creating a reconnection storm

Why it happened after 24 hours:
Container orchestration systems (Docker Swarm/Kubernetes) periodically restart
pods. Over time, workers reconnect multiple times. Each reconnection had a chance
of hitting the race condition. Eventually the race manifested and caused the
connection storm.

Changes:
--------

weed/worker/client.go:
- Start handleIncoming and handleOutgoing goroutines BEFORE sending registration
- Use sendRegistration() instead of sendRegistrationSync()
- Ensures only ONE goroutine (handleIncoming) calls stream.Recv()
- Eliminates race condition entirely

weed/admin/dash/worker_grpc_server.go:
- Clean up old connection when worker reconnects with same ID
- Cancel old connection context to stop its goroutines
- Prevents resource leaks and stale connection accumulation

Impact:
-------
Before: Random 'context canceled' errors during reconnection, rapid reconnection
        cycles, resource leaks, requires manual restart to recover
After:  Reliable reconnection, single Recv() goroutine, proper cleanup,
        stable operation over 24+ hours

Testing:
--------
Build verified successful with no compilation errors.

How to reproduce the bug:
1. Start admin server and worker
2. Restart admin server (simulates container recreation)
3. Worker reconnects
4. Race condition may manifest, causing 'context canceled' error
5. Observe rapid reconnection cycles in logs

The fix is backward compatible and requires no configuration changes.

4aa50bfa6a fix: EC rebalance fails with replica placement 000 (#7812)
* fix: EC rebalance fails with replica placement 000

This PR fixes several issues with EC shard distribution:

1. Pre-flight check before EC encoding
   - Verify target disk type has capacity before encoding starts
   - Prevents encoding shards only to fail during rebalance
   - Shows helpful error when wrong diskType is specified (e.g., ssd when volumes are on hdd)

2. Fix EC rebalance with replica placement 000
   - When DiffRackCount=0, shards should be distributed freely across racks
   - The '000' placement means 'no volume replication needed' because EC provides redundancy
   - Previously all racks were skipped with error 'shards X > replica placement limit (0)'

3. Add unit tests for EC rebalance slot calculation
   - TestECRebalanceWithLimitedSlots: documents the limited slots scenario
   - TestECRebalanceZeroFreeSlots: reproduces the 0 free slots error

4. Add Makefile for manual EC testing
   - make setup: start cluster and populate data
   - make shell: open weed shell for EC commands
   - make clean: stop cluster and cleanup

* fix: default -rebalance to true for ec.encode

The -rebalance flag was defaulting to false, which meant ec.encode would
only print shard moves but not actually execute them. This is a poor
default since the whole point of EC encoding is to distribute shards
across servers for fault tolerance.

Now -rebalance defaults to true, so shards are actually distributed
after encoding. Users can use -rebalance=false if they only want to
see what would happen without making changes.

* test/erasure_coding: improve Makefile safety and docs

- Narrow pkill pattern for volume servers to use TEST_DIR instead of
  port pattern, avoiding accidental kills of unrelated SeaweedFS processes
- Document external dependencies (curl, jq) in header comments

* shell: refactor buildRackWithEcShards to reuse buildEcShards

Extract common shard bit construction logic to avoid duplication
between buildEcShards and buildRackWithEcShards helper functions.

* shell: update test for EC replication 000 behavior

When DiffRackCount=0 (replication "000"), EC shards should be
distributed freely across racks since erasure coding provides its
own redundancy. Update test expectation to reflect this behavior.

* erasure_coding: add distribution package for proportional EC shard placement

Add a new reusable package for EC shard distribution that:
- Supports configurable EC ratios (not hard-coded 10+4)
- Distributes shards proportionally based on replication policy
- Provides fault tolerance analysis
- Prefers moving parity shards to keep data shards spread out

Key components:
- ECConfig: Configurable data/parity shard counts
- ReplicationConfig: Parsed XYZ replication policy
- ECDistribution: Target shard counts per DC/rack/node
- Rebalancer: Plans shard moves with parity-first strategy

This enables seaweed-enterprise custom EC ratios and weed worker
integration while maintaining a clean, testable architecture.

* shell: integrate distribution package for EC rebalancing

Add shell wrappers around the distribution package:
- ProportionalECRebalancer: Plans moves using distribution.Rebalancer
- NewProportionalECRebalancerWithConfig: Supports custom EC configs
- GetDistributionSummary/GetFaultToleranceAnalysis: Helper functions

The shell layer converts between EcNode types and the generic
TopologyNode types used by the distribution package.

* ec: improve data and parity shard distribution across racks

- Add shardsByTypePerRack helper to track data vs parity shards
- Rewrite doBalanceEcShardsAcrossRacks for two-pass balancing:
  1. Balance data shards (0-9) evenly, max ceil(10/6)=2 per rack
  2. Balance parity shards (10-13) evenly, max ceil(4/6)=1 per rack
- Add balanceShardTypeAcrossRacks for generic shard type balancing
- Add pickRackForShardType to select destination with room for type
- Add unit tests for even data/parity distribution verification

This ensures even read load during normal operation by spreading
both data and parity shards across all available racks.

* ec: make data/parity shard counts configurable in ecBalancer

- Add dataShardCount and parityShardCount fields to ecBalancer struct
- Add getDataShardCount() and getParityShardCount() methods with defaults
- Replace direct constant usage with configurable methods
- Fix unused variable warning for parityPerRack

This allows seaweed-enterprise to use custom EC ratios while
defaulting to standard 10+4 scheme.

Makefile improvements:
- Save PIDs for each volume server for precise termination
- Use PID-based killing in stop target with pkill fallback
- Use more specific pkill patterns with TEST_DIR paths

Documentation:
- Document jq dependency in README.md

Rebalancer fix:
- Fix duplicate shard count updates in applyMovesToAnalysis
- All planners (DC/rack/node) update counts inline during planning
- Remove duplicate updates from applyMovesToAnalysis to avoid double-counting

* test/erasure_coding: use mktemp for test file template

Use mktemp instead of hardcoded /tmp/testfile_template.bin path
to provide better isolation for concurrent test runs.

f4cdfcc5fd Add cluster.raft.leader.transfer command for graceful leader change (#7819)
* proto: add RaftLeadershipTransfer RPC for forced leader change

Add new gRPC RPC and messages for leadership transfer:
- RaftLeadershipTransferRequest: optional target_id and target_address
- RaftLeadershipTransferResponse: previous_leader and new_leader

This enables graceful leadership transfer before master maintenance,
reducing errors in filers during planned maintenance windows.

Ref: https://github.com/seaweedfs/seaweedfs/issues/7527

* proto: regenerate Go files for RaftLeadershipTransfer

Generated from master.proto changes.

* master: implement RaftLeadershipTransfer gRPC handler

Add gRPC handler for leadership transfer with support for:
- Transfer to any eligible follower (when target_id is empty)
- Transfer to a specific server (when target_id and target_address are provided)

Uses hashicorp/raft LeadershipTransfer() and LeadershipTransferToServer() APIs.

Returns the previous and new leader in the response.

* shell: add cluster.raft.leader.transfer command

Add weed shell command for graceful leadership transfer:
- Displays current cluster status before transfer
- Supports auto-selection of target (any eligible follower)
- Supports targeted transfer with -id and -address flags
- Provides clear feedback on success/failure with troubleshooting tips

Usage:
  cluster.raft.leader.transfer
  cluster.raft.leader.transfer -id <server_id> -address <grpc_address>

* master: add unit tests for raft gRPC handlers

Add tests covering:
- RaftLeadershipTransfer with no raft initialized
- RaftLeadershipTransfer with target_id but no address
- RaftListClusterServers with no raft initialized
- RaftAddServer with no raft initialized
- RaftRemoveServer with no raft initialized

These tests verify error handling when raft is not configured.

* shell: add tests for cluster.raft.leader.transfer command

Add tests covering:
- Command name and help text validation
- HasTag returns false for ResourceHeavy
- Validation of -id without -address
- Argument parsing with unknown flags

* master: clarify that leadership transfer requires -raftHashicorp

The default raft implementation (seaweedfs/raft, a goraft fork) does not
support graceful leadership transfer. This feature is only available when
using hashicorp raft (-raftHashicorp=true).

Update error messages and help text to make this requirement clear:
- gRPC handler returns specific error for goraft users
- Shell command help text notes the requirement
- Added test for goraft case

* test: use strings.Contains instead of custom helper

Replace custom contains/containsHelper functions with the standard
library strings.Contains for better maintainability.

* shell: return flag parsing errors instead of swallowing them

- Return the error from flag.Parse() instead of returning nil
- Update test to explicitly assert error for unknown flags

* test: document integration test scenarios for Raft leadership transfer

Add comments explaining:
- Why these unit tests only cover 'Raft not initialized' scenarios
- What integration tests should cover (with multi-master cluster)
- hashicorp/raft uses concrete types that cannot be easily mocked

* fix: address reviewer feedback on tests and leader routing

- Remove misleading tests that couldn't properly validate their
  documented behavior without a real Raft cluster:
  - TestRaftLeadershipTransfer_GoraftNotSupported
  - TestRaftLeadershipTransfer_ValidationTargetIdWithoutAddress

- Change WithClient(false) to WithClient(true) for RaftLeadershipTransfer
  RPC to ensure the request is routed to the current leader

* Improve cluster.raft.transferLeader command

- Rename command from cluster.raft.leader.transfer to cluster.raft.transferLeader
- Add symmetric validation: -id and -address must be specified together
- Handle case where same leader is re-elected after transfer
- Add test for -address without -id validation
- Add docker compose file for 5-master raft cluster testing
