RE: SVN question

svn does not always return success. For instance:

> svn ls
svn: '.' is not a working copy
> echo $?
1

I think this is the more normal mode that I script against. I'm not sure why the update sub-command is so forgiving.

Steve,

Thank you for taking the time.

I also saw this....I was wondering what users do to get something similar working.

The same thing happens under Perforce. The command "p4" always returns a
successful exit code. The way around that is the odd "-s" switch which causes the
tool to emit a string like "exit: #" where the underlying commands success or failure
was specified. Is there perhaps some similar technique for SVN?

I checked the svn Global Options and did not see anything similar.

I suppose that I can just use a pipe and watch for strings that I expect.....

Take care,

Christopher

Christopher,

The problem is not with your perl code. Apparently, update returns success if you give it a path that does not exist in the current working directory.

Ø svn update foobar

At revision 3158.

Ø echo $?

0

For Svn 1.6.15, anyway. Seems to hold for linux & windows.

Hello,

I have been wondering how best to capture errors from
the SVN command line.

I wanted to show you how a basic test is failing.

Consider the simple code snippet:
==========================================
use strict;
my $options=" --username builduser --password XXXX";

chdir("C:\\source");
my $output = `svn update --depth=infinity mang $options`;

die "svn failed with errorcode $?" if $?;
print "We survived!\n";
==========================================

This command works if the "mang" above is changed to "main"
(which does exist at c:\source).

However, both code have this result:
==========================================
C:\source\cm\script>perl svntest.pl
We survived!

C:\source\cm\script>perl svntest.pl
We survived!
==========================================

What am I doing wrong?

Chris
