Bug ID: 11545
Summary: -A (preserve ACLs) with --link-dest=DIR fails when DIR
has a directory with the same file's name
Product: rsync
Version: 3.1.0
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5
Component: core
Assignee: wayned at samba.org
Reporter: famzah at famzah.net
QA Contact: rsync-qa at samba.org
A few lines of code speak for dozens of words:
[code]
TESTDIR=~/rsync-link-bug
mkdir "$TESTDIR"
cd "$TESTDIR"
# populate source data
mkdir data
touch data/file.txt
getfacl data/file.txt # make sure you support ACL
# populate backup data
for i in 0 1 ; do mkdir backup.$i backup.$i/data ; done
touch backup.0/data/file.txt # create file
mkdir backup.1/data/file.txt # create directory with the same name
# reproduce the bug
rsync -a -A --link-dest "$TESTDIR/backup.1" "$TESTDIR/data" "$TESTDIR/backup.0"
[/code]
This bug affects rsync 3.1.0+ including the "dev" version:
[code]
famzah at vbox:~/rsync-link-bug$ ~/a/rsync/rsync-3.0.9/rsync -a -A --link-dest
"$TESTDIR/backup.1" "$TESTDIR/data" "$TESTDIR/backup.0"
# 3.0.9: OK, no error; works as expected
famzah at vbox:~/rsync-link-bug$ ~/a/rsync/rsync-3.1.1/rsync -a --link-dest
"$TESTDIR/backup.1" "$TESTDIR/data" "$TESTDIR/backup.0"
# 3.1.1: without "-A" works OK too
[/code]
Versions 3.1.0, 3.1.1 and 3.1.2pre1 are affected:
