Inconsistent behavior in cat command
When I was trying to come up with a patch for issue 3713, I observed the
following.
For example I have two files 1.txt and 2.txt in a repository located at
file:///tmp/testrepo
svn cat behaves differently for local paths and URLs. See the
illustration below.
noorul@noorul:/tmp/wc/testrepo$ svn cat 1.txt 2.txt
1
2
A) Local non-existent target followed by existing target
noorul@noorul:/tmp/wc/testrepo$ svn cat 3.txt 1.txt
svn: warning: '/tmp/wc/testrepo/3.txt' is not under version control
1
B) Non-existent URL followed by existing URL
noorul@noorul:/tmp/wc/testrepo$ svn cat ^/3.txt ^/1.txt
svn: File not found: revision 1, path '/3.txt'
In case A, even though the first target was non-existent it performs cat
operation on the second target but in the case of B, svn errors out at
the first failure itself.
I am not sure about behavior of other svn commands which accepts
multiple targets. When I discussed this Julian in IRC, he said a
discussion is needed to come up with standardized behavior across svn
commands. Any thoughts?
Thanks and Regards

I will be re-submitting this patch once the discussion going on in the
following thread concludes.
http://svn.haxx.se/dev/archive-2011-01/0210.shtml
I think you can remove this patch from your watch list because this will
be combined with some more changes to cat command.
Thanks and Regards

Initially this thread was monitored by Julian and now I found out that
he is busy. It will be great if someone else can take a look at this
one.

I checked 'svn info' and it behaves the same way for both wc and URL.

I figured out that for non-existent URL path, svn_client_cat2 returns
SVN_ERR_FS_NOT_FOUND which needs to be caught by svn_cl__try. Therefore
I passed this code as one the arguments.
Attached is the patch. All tests pass with this patch.
Log
[[[
Make 'svn cat' not to error out when one of the URL targets do not
exist.
* subversion/svn/cat-cmd.c
(svn_cl__cat): Pass SVN_ERR_FS_NOT_FOUND to svn_cl__try in order to
catch the error, print warning and proceed with other targets.

Hi Noorul.
A good way to start a discussion of this sort is to:
list the possible solutions;
find out and describe how the other subcommands behave;
say what you think is good and bad about each possible solution;
say which solution you think we should choose.
That will make it much easier for readers to respond.
