Subject: svn generates long lists of empty diffs with --diff-cmd
Hi,
I noticed that SVN generates a lot of spurious diffs when using a
--diff-cmd option that look like this:
Index: arch/alpha/boot/tools/objstrip.c
==========================================================
=========
Index: arch/alpha/boot/Makefile
==========================================================
=========
Is it possible to suppress such empty diffs? This makes the tools like
ReviewBoard (www.reviewboard.org) examine a lot of unchanged files and
slows them down considerably and unnecessary.
What argument do you pass to --diff-cmd ?
svn diff --diff-cmd=diff
Is it possible that the files are actually different, but your diff
command reports that they are not different (e.g. after normalizing
whitespace). I think this header is printed on changed files, right
before invoking the diff command.
No, plain 'svn diff' does not show any differences, not even
properties. For example:
[aneyman@rhel-build2 src]$ svn diff $URL/SETUP.bash SETUP.bash
[aneyman@rhel-build2 src]$ svn diff --diff-cmd=diff $URL/SETUP.bash
SETUP.bash
Index: SETUP.bash
===================================================================
Some more information:
- While the properties on the file itself are the same, the inherited
properties differ (at least, svn:mergeinfo on the parent directory).
- This behavior is observed on 1.10.0-dev, 1.9.x and 1.8.x. Subversion
1.7.x does not display these spurious "Index:" lines.
Regards,
Alexey.
