Git-hooks pre-push script does not receive input on stdin

Git-hooks pre-push script does not receive input on stdin

Is this a bug in git?  Or am I just a shell noob?

Thanks in advance,

David

I assume that you have the right version of Git ?
You can look into the source of Git, to be more exact the test suite:
t/t5571-pre-push-hook.sh

When I play a little but with the script,
(Replace the diff with test_cmp, add a line:
diff --git a/t/t5571-pre-push-hook.sh b/t/t5571-pre-push-hook.sh
index 6f9916a..01db2fb 100755
--- a/t/t5571-pre-push-hook.sh
+++ b/t/t5571-pre-push-hook.sh
@@ -42,6 +42,7 @@ export COMMIT2
 write_script "$HOOK" <<'EOF'
 echo "$1" >actual
 echo "$2" >>actual
+echo hello >>actual
 cat >>actual
 EOF
-------------
and finally run it like this:

debug=t verbose=t ./t5571-pre-push-hook.sh  2>&1 | less
I get something like this:

--- expected    2014-03-23 07:15:58.000000000 +0000
+++ actual      2014-03-23 07:15:58.000000000 +0000

So the question is, if your push simply doesn't have anything to push,
because everything is up to date?
And in this case there is nothing on STDIN?

If the problem still exists, feel free to post a script how to reproduce it
here to the list, t5571 may be a source of inspiration.

You are correct, it was a misunderstanding on my part.  I have
suggested a patch to clarify the pre-push documentation in a separate
thread.

Thanks for pointing that out!
