--diff-cmd question
Hi all out there!
Trying to use ExamDiff with the --diff-cmd I get the following error:
D:\>svn diff -r BASE --diff-cmd d:\tmp\examdiff\examdiff.exe
d:\tmp\testworkcopy
\ridinger\niemeyer\prints\index.htm
Index: D:/Tmp/TestWorkCopy/Ridinger/niemeyer/prints/index.htm
=================================================
==================
svn: Error calling external program
svn: svn_io_run_cmd: error exitwhy 2 for process
'd:\tmp\examdiff\examdiff.exe'
Same error if I ommit -r BASE or define Examdiff in subversion/conf.
In a Windows message I am told that Examdiff has caused an error
and a log were created, but I cannot find this log.
TIA for any help - Jan Hendrik

I wondered why it said exitwhy, so I looked it up. Exitwhy is not
exitcode, and 2 means that the process exited because of a signal
(APR_PROC_SIGNAL).

It is a Windows program, if well-known I do not know, but it was
mentioned for TSVN.
It takes the command line [Filename1] [Filename2] [Options].
Options are concerned with considering white spaces etc.
I tried Winmerge (of Sourceforge) now, too, and it works - sort of: it
ignores the filename and shows a directory listing. Not what I want.
If invoked with filenames it shows the file, not the folder. In TSVN it
has worked just as ExamDiff.
Testing further by giving svn diff the filename in two different working
copies Winmerge comes up with *two* windows and I now see it
compares each folder (not the file) against itself.
Next I took WinDiff. It just gives me a list of unrelated command
line options. It should be invoked with either one or two files. In the
first case it should compare the file with, say, -r BASE. There is no
difference if both filenames are handed over.
GNU Diff works. So it seems none of the Windows tools takes the
parameters in the GNU/DOS style and TSVN makes wrappers for
them.

The external diff program exited with a return value of 2. Subversion
expects the program to return 0 or 1. You may have to use the wrapper
program or script to convert the ExamDiff return value.
I don't know what an ExamDiff return value of 2 means but I'd guess it
indicates that the program failed, possibly because it doesn't
understand GNU diff style command line arguments.
