post-commit question

[Jeroen Coumans <je...@jeroencoumans.nl>]

Hi,

Our company sells customized Mambo code. We import data from the latest 
stable release to /trunk/ and use /branches/client/ for our own 
customizions. I'd like to use a post-commit hook which checks which 
branch the commit is made (eg. /branches/client1/) and checks out that 
branch to a specific directory.
Eg. if some commits to /branches/client1/, the post-commit script would 
export /branches/client1/ to /www/client1/

Is this possible? Thanks for any answers.

I also found this quite frustrating at times.
For one, unless the user that the script executes under (in my case , Fedora 
Core uses apache) has a login shell (which sets path,etc.) then you will have 
to use absolute paths, like /bin/echo or come up with a scheme for getting 
paths (like sourcing a common file)

I do stuff like this:
<command> >> /tmp/hook_log 2 >&1

This will append output from your command to the /tmp/hook_log file 
redirecting both stdout and stderr.

Note that if you want output to make it to subversion, i.e. Cannot commit 
because you didn't do something/don't have permissions, it must be on stderr.

Here is a pre-commit check for committing to tags:

/usr/bin/svnlook changed -t $2 $1 | grep "^U\W*tags" && /bin/echo "CANNOT 
COMMIT TO TAGS!!!" 1>&2  && exit 1

The 
/bin/echo <message> 1>&2
does a redirect to stderr.

Hope this helps,
Ian

Aha, ok, thanks! My scripting is not very good, but I hope I can manage 
this by myself. What would be the best way to test and debug the 
post-commit hook? I have setup a test repository to test it out, but it 
doesn't show me the output of the script. I have the following:

#!/bin/sh
set -x

REPOS="$1"
REV="$2"
branch='svnlook changed /subversion/mambo/ | cut -d / -f 3'

echo "REPOS = $REPOS"
echo "REV = $REV"
echo "branch = $branch"

How do I view the output?

Of course it's possible.  Have your post-commit script use 'svnlook' to
examine the commit that just happened, and act accordingly.
