After adding an "External Async Post Receive Hook", any push LOOPS ENDLESSLY

[chrishahn1138]

Added:  Atlassian Bitbucket v4.14.4

From my own repos setting page:

<SERVER>/users/christopher.hahn/repos/hooktest/settings/hooks

this is the text from the hook config web-dialog:
===============================

External Async Post Receive Hook

Executable: basictest.sh
Path to executable to run.

Safe mode [X] Look for hooks only in safe dir

Hooks will be searched only in <stash-home-dir>/external-hooks/
===============================

The script:
/var/atlassian/bitbucket-home/external-hooks/basictest.sh
is a classic, off the net:
===============================

#!/bin/bash

(
echo "Script name: $0"
echo "Positional arguments: ${@}"
echo "STASH_USER_NAME: $STASH_USER_NAME"
echo "STASH_USER_EMAIL: $STASH_USER_EMAIL"
echo "STASH_REPO_NAME: $STASH_REPO_NAME"
echo "STASH_IS_ADMIN: $STASH_IS_ADMIN"
while read from_ref to_ref ref_name; do
echo "Ref update:"
echo " Old value: $from_ref"
echo " New value: $to_ref"
echo " Ref name: $ref_name"
echo " Diff:"
git show $from_ref..$to_ref | sed 's/^/ /'
done
) | tee -a /tmp/external-hooks-test.log

===============================

The script is 755 and runs fine from the command line.

BUT, when I push any change, the console loops over the same output:
===============================
$ git push newbranch

Has anyone else seen this?

I got my own answer: I had first tried to get this working using a script in the traditional location...the repos hook directory.

Well, I had left a copy of some version of my script down on the post-receive.d sub-directory.

What I was seeing that that "second script" being run, over and over and over.

The idea here is that one should just stay away from using hooks with Bamboo *unless* you are using a plugin to drive them.

I need to add that I reduced the script down to just:

#!/bin/sh
echo "IN SCRIPT"
exit 0

and reran my test. 

The result did not loop, but it just hung without returning:

$ gush master
Counting objects: 3, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 342 bytes | 0 bytes/s, done.
Total 3 (delta 1), reused 0 (delta 0)
Killed by signal 2.
fatal: The remote end hung up unexpectedly
error: error in sideband demultiplexer

...check out that message when I killed the process...interesting!

More Data...just added as a comment on the related card:

I have queries on two different boards, the Atlassian Community and the Github site of the plugins creators.  No responses yet.

I am now testing using the "safe dir" and the simplest of scripts:

[stash@XXXXX 765]$ /var/atlassian/bitbucket-home/external-hooks/test.sh
IN SCRIPT: Test

[stash@XXXXX 765]$ cat !$
cat /var/atlassian/bitbucket-home/external-hooks/test.sh
#!/bin/sh

echo "IN SCRIPT: Test"
exit 0

Note the simplicity of the script.

The error seen in the log when one of these pushes hangs:
