* fix(s3): return ETag header for directory marker PutObject requests
The PutObject handler has a special path for keys ending with "/" (directory
markers) that creates the entry via mkdir. This path never computed or set
the ETag response header, unlike the regular PutObject path. AWS S3 always
returns an ETag header, even for empty-body puts.
Compute the MD5 of the content (empty or otherwise), store it in the entry
attributes and extended attributes, and set the ETag response header.
Fixes#8682
* fix: handle io.ReadAll error and chunked encoding for directory markers
Address review feedback:
- Handle error from io.ReadAll instead of silently discarding it
- Change condition from ContentLength > 0 to ContentLength != 0 to
correctly handle chunked transfer encoding (ContentLength == -1)
* fix hanging tests
* glog: add --log_rotate_hours flag for time-based log rotation
SeaweedFS previously only rotated log files when they reached MaxSize
(1.8 GB). Long-running deployments with low log volume could accumulate
log files indefinitely with no way to force rotation on a schedule.
This change adds the --log_rotate_hours flag. When set to a non-zero
value, the current log file is rotated once it has been open for the
specified number of hours, regardless of its size.
Implementation details:
- New flag --log_rotate_hours (int, default 0 = disabled) in glog_file.go
- Added createdAt time.Time field to syncBuffer to track file open time
- rotateFile() sets createdAt to the time the new file is opened
- Write() checks elapsed time and triggers rotation when the threshold
is exceeded, consistent with the existing size-based check
This resolves the long-standing request for time-based rotation and
helps prevent unbounded log accumulation in /tmp on production systems.

* glog: default log_rotate_hours to 168 (7 days)
Enable time-based rotation by default so log files don't accumulate
indefinitely in long-running deployments. Set to 0 to disable.
* glog: simplify rotation logic by combining size and time conditions
Merge the two separate rotation checks into a single block to
eliminate duplicated rotateFile error handling.
* glog: use timeNow() in syncBuffer.Write and add time-based rotation test
Use the existing testable timeNow variable instead of time.Now() in
syncBuffer.Write so that time-based rotation can be tested with a
mocked clock.
Add TestTimeBasedRollover that verifies:
- no rotation occurs before the interval elapses
- rotation triggers after the configured hours
