post-commit hook completely fails
I've done all I can to diagnose this, and I can't figure it out. I've
set up hooks just fine on at least two other different systems, but here
nothing works.
So I create a test repository:
$ uname -a
Linux maniac 2.6.18-hardened #3 SMP Thu Mar 15 23:20:05 EDT 2007 x86_64
AMD Sempron(tm) Processor 2800+ AuthenticAMD GNU/Linux
$ grep User /etc/apache2/httpd.conf
User apache
$ cd /tmp
$ svnadmin create svn
$ sudo chown -R apache:apache svn
$ sudo chmod -R og+w svn
$ cd svn/hooks/
$ cat > post-commit
#!/bin/bash
/bin/true
$ chmod 777 post-commit
And I set it up via apache:
<VirtualHost 65.111.171.224:80>
ServerName svn2
DocumentRoot /tmp
ErrorLog /tmp/error_log
CustomLog /tmp/access combined
<Directory /tmp>
Order allow,deny
Allow from all
</Directory>
<Location />
DAV svn
SVNPath /tmp/svn
</Location>
</VirtualHost>
And then:
$ svn co http://svn2/ test
Checked out revision 0.
$ cd test/
$ touch x
$ svn add x
A x
$ svn ci -m -
Adding x
Transmitting file data .
Committed revision 1.
Warning: 'post-commit' hook failed with error output:
What else can I do? It's completely failing. If I completely remove
the post-commit file, it runs cleanly, but if *anything* is there, it
fails with no message.

Hooks have no environment. The system does not know where to find 'cat'
(or 'echo' for that matter). Use '/bin/cat' or '/bin/echo' instead.

Please make that "echo" instead of "cat" :-) I doubt there's a file called
"I
am running" around ;-)
BTW, for such debugging I do things like this:
$ date >>/tmp/debug.log
That way I not only know it happened but also when.

You could do a simple
$ cat "I am running" >> /somewriteableDirectory/postcommitop.txt
in your hook file and see if the file gets this line. This will atleast
assure that your hook file is running.

For me, most of the time debugging hooks starts with a look int e
Apache logs, in particular the errors log. That will often point me
to the issue without adding any debug output to the hook.
Does that say anything in this case?

Have you tried to output a message to stderr and then exit the script
with a non-zero exit code?
for example:
# echo "I'm doing it wrong" >&2
# exit 1
What happens if you do that?
(I haven't read all your previous posts so I apologize if you've
covered that already.)

Just to rule out the obvious: Are you sure the post-commit hook
you are looking at is the post-commit hook that's being run? In other words,
are you looking in the right repository?

Good point. I've tried sending text to logs in the past is how I know,
to be honest. So to repeat and be clear:
$ cat > post-commit
#!/bin/bash
/bin/date >> /tmp/pc.txt
/bin/true
$ chmod 777 post-commit
Still:
Transmitting file data .
Committed revision 5.
Warning: 'post-commit' hook failed with error output:
And on the host:
$ ls -l /tmp/pc.txt
ls: cannot access /tmp/pc.txt: No such file or directory
The file doesn't exist. If I run that script manually, it works. Even
if I run it as the apache user, and with "env -".
Like I said much earlier, if there is no "post-commit" file, I get no
error. But if there is anything there, an empty shell script, a symlink
to /bin/true, anything .. I get the "failed with error output" with no
error output message. Something is failing, but I don't know what, and
I don't know how to diagnose what.
P.S. To others in this thread: echo is a builtin of bash, so since this
is a bash script, the path to echo wouldn't really need to be supplied.

How can you tell it is not running if all it does is invoke /bin/true?
(IOW, show us a transcript of the symptoms.)

I can't make this script any simpler, but it still does not run. How do
I get debugging information to figure this out? Nothing shows in any
output or log I can find.

Yep, read my prior posts. Creating the file named "post commmit" is
followed immediately by "chmod 777 post-commit" in this test case.

Nope.

Are you running SELinux and if so have you used chcon to set the
security context so that the svnserve or apache process can execute
the hook script? This may be relevant:

Not completely. Post-anything exit codes only generate warning. The commit
goes through fine. From what Anthony has shown, the warning is expected when
the hook exited with exit 1 or if it could not execute post-commit.
But since his post-commit is supposed to have only /bin/true in it, I have
absolutely no idea what is going on.

The exit code of a post-anything hook is ignored (as far as I know -
and I've just put an "exit 1" at the end of the post-commit hook of my
test repository)
You are sure that execution right are set properly? Because can't
imagine anything besides the hook not being executable at all that
could cause such effect (but that may originate in lack of imagination
8-).

When you execute the post-commit from command line, does it throw a non-zero
exit status? [In reality, the post-commit is run without an env, which is
different from running on the command line, but it would be nice to know if
it runs from the command line]

You did see where, in my original mail, I set the entire content of the
script to:
#!/bin/bash
/bin/true
? I can't make it any simpler than that. I even did "ln -s /bin/true
post-commit" and I get exactly the same result.

Hi Anthony,
Couple of tests you can perform to narrow the problem.
1) place a "exit 0" at the top of your hook file.
2) keep moving the "exit 0" down the file till you can reproduce the
error.
I suspect your script is failing with a syntax error, which returns a
non-zero to subversion server.
Thanks
Lakshman
