svn commit: r1677739 - in /subversion/branches/1.9.x: ./ STATUS
subversion/libsvn_fs_fs/cached_data.c
subversion/tests/libsvn_fs_fs/fs-fs-pack-test.c
Author: svn-role
Date: Tue May 5 04:00:15 2015
New Revision: 1677739
URL: http://svn.apache.org/r1677739
Log:
Merge the r1676667 group from trunk:
* r1676667, r1677267
'EOF found' error when reading FSFS data (issue #4577).
Justification:
Without this change, users may not be able to read or modify the
affected node(s), usually a directory. While the data is not lost,
it becomes inaccessible.
Notes:
The rather trivial fix is in r1676667, r1677267 adds a test case.
