custom_hook.rb:72:in `popen': Permission denied - hooks/post-receive.d/__pycache__ (Errno::EACCES)

I'm not sure if I setup something wrong, or there is something weird.

remote: /var/lib/gitolite/local/hooks/common/lib/git_hosting/custom_hook.rb:72:in `popen': Permission denied - hooks/post-receive.d/__pycache__ (Errno::EACCES)
remote:         from /var/lib/gitolite/local/hooks/common/lib/git_hosting/custom_hook.rb:72:in `block in call_extra_hooks'
remote:         from /var/lib/gitolite/local/hooks/common/lib/git_hosting/custom_hook.rb:69:in `each'
remote:         from /var/lib/gitolite/local/hooks/common/lib/git_hosting/custom_hook.rb:69:in `call_extra_hooks'
remote:         from /var/lib/gitolite/local/hooks/common/lib/git_hosting/custom_hook.rb:17:in `exec'
remote:         from hooks/post-receive:15:in `<main>'

In addition, I had to install python onto server so I don't get unexpected error:
Calling additional post-receive hooks...

• Executing extra hook 'hooks/post-receive.d/mail_notifications'
  remote: /usr/bin/env: 'python': No such file or directory

removed all hooks, reinstalled them (with current redmine_git_hosting), issue seems disappeared.

[tomhub]

Unfortunatelly, it's back.

So I tested this a bit more. If I delete local/hooks/common/post-receive.d/__pycache__ directory, then first git push proceeds without an error. However, further pushed produces warnings as above.

My guess is that hooks/common/post-receive.d/__pycache__ gets in the list of hooks by mistake.
In file hooks/common/lib/git_hosting/custom_hook.rb I can see call to get_executables('hooks/post-receive.d') which yields all the files in hooks/common/post-receive.d/ directory including the __pycache__ directory (I have tested this with piece of ruby code).
I have extended the skip loop test in get_executables function to leave out __pycache__ like this:
next if item == '.' || item == '..' || item == '__pycache__'
This patch worked for me.

Thank you @fairf4x for your solution. I have modified line 55 to:

next if ['.', '..', '__pycache__'].include? item

And it seems this fixed the problem for me as well. I assume the code will be updated in repository as well.
