git: empty arguments in post-receive hook

I'm writing post-receive hook basing on the post-receive-email script from the contrib dir, but it seems that the oldrev and newrev arguments are empty.

The script looks like this:

#!/bin/bash

oldrev=$(git rev-parse $1)
newrev=$(git rev-parse $2)

The script runs on push, but all $1, $2, $oldrev and $newrev are empty. Should I configure something to get it running?

(The repository was created by gitolite if it does matter)

I stumbled into this problem while setting up a continuous integration server. Since the arguments are not passed to post-receive via the command line, but are passed over STDIN, you have to use the read command to fetch them. Here is how I did it:

#!/bin/sh
read oldrev newrev refname
BRANCH=${refname#refs/heads/} 
curl --request POST "http://my.ci.server/hooks/build/myproject_$BRANCH"

Actually, I don't accept the "it takes no arguments", because the sample script post-receive.sample is having the following comment:

# The "post-receive" script is run after receive-pack has accepted a pack
# and the repository has been updated.  It is passed arguments in through
# stdin in the form
#  <oldrev> <newrev> <refname>
# For example:
#  aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master
