svn_client_diff_peg4() returns inverse diff
Hi,
Calling svn_client_diff_peg4() returns the same diff even with reversed
revisions:
svn_client_diff_peg4(.... r7(peg),
r7(start),
WC(end),....)
and
svn_client_diff_peg4(.... r7(peg),
WC(start),
r7(end),....)
return the exact same diff (always r7:WC, never WC:r7).
Unfortunately, I can't provide a script to reproduce this, because the
CL client doesn't know WC or WORKING as a valid revision argument.
This happens with the Subversion trunk r25805.
I noticed this when testing the "compare with working copy" feature in
the TSVN log dialog, where a patchfile is created from the selected
revision to the working copy, and that patchfile is then 'applied' to
the working copy to get the files in the selected revision (that's
faster than to fetch all the files individually in full).

As I already mentioned, it's not possible to give an example with the
command line: it doesn't understand WC or WORKING as revision arguments.
The problem only occurs if one of the revisions to diff is 'working
copy', not a revision number.

Stefan, can you provide an example with the command-line using
specific WORKING revisions? I tried the following (which exercises
svn_client_diff_peg4), but was unable to reproduce -- switching the
START and END revisions did reverse the diff output.
svn di -r25820:25862 subversion/libsvn_client@25862
