Summary: rsync fails with --inplace, --link-dest and --no-whole-
file
Product: rsync
Version: 2.6.8
Platform: x86
OS/Version: Linux
Status: NEW
Severity: major
Priority: P3
Component: core
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
System: Debian sarge (x86) with a locally compiled 2.6.8 version of rsync with
the ACL patches applied. Kernel updated to 2.6.16.20.
The command below fails if there is a reference file in "/tmp/test/b" that is
slightly different to the file in "/tmp/test/a" and the destination file does
not exist in "/tmp/test/c".
rsync -a --no-whole-file --inplace --link-dest=/tmp/test/b tmp/test/a/
tmp/test/c/
If rsync is run with -vvvv, the RSYNC algorithm appears to run correctly and
determine the blocks in the file that are missing. Unfortunately, only the
changed data is written to the file in "/tmp/test/c/" and the rest of the file
is zeros.
I suspect this is because an empty destination file is created when the file
doesn't exist rather than hard-linking the destination file to the link-dest
file before performing the in-place copy.
