如何在ruby钩子中加载python文件? [英] How to load the python file in ruby hook?

问题描述

我试图添加钩子以忽略gitlab中提交的二进制文件，所以我在/opt/gitlab/embedded/service/gitlab-shell/lib中添加了新的python(.py)钩子，并将该文件加载到/opt/gitlab/embedded/service/gitlab-shell/hooks/pre-receive.rb

I trying to add the hook to ignore the binary file committing in gitlab, SO I added the new python(.py) hook in /opt/gitlab/embedded/service/gitlab-shell/lib and i loaded that file in /opt/gitlab/embedded/service/gitlab-shell/hooks/pre-receive.rb

但是当我尝试提交文件时，在提交屏幕中出现了以下异常

But When I tried to commit the file i got the below exception in commit screen

远程:钩子/预接收:17:在require_relative': cannot load such file -- /opt/gitlab/embedded/service/gitlab-shell/lib/gitlab_ignore_binary.py (LoadError) remote: from hooks/pre-receive:17:in'

remote: hooks/pre-receive:17:in require_relative': cannot load such file -- /opt/gitlab/embedded/service/gitlab-shell/lib/gitlab_ignore_binary.py (LoadError) remote: from hooks/pre-receive:17:in'

我的接收前挂钩文件是

#!/opt/gitlab/embedded/bin/ruby
# Fix the PATH so that gitlab-shell can find git-upload-pack and friends.
ENV['PATH'] = '/opt/gitlab/bin:/opt/gitlab/embedded/bin:' + ENV['PATH']

#!/usr/bin/env ruby
#!/usr/bin/env python

# This file was placed here by GitLab. It makes sure that your pushed commits
# will be processed properly.

refs = $stdin.read
key_id = ENV.delete('GL_ID')
protocol = ENV.delete('GL_PROTOCOL')
repo_path = Dir.pwd
gl_repository = ENV['GL_REPOSITORY']

require_relative '../lib/gitlab_ignore_binary.py'
require_relative '../lib/gitlab_custom_hook'
require_relative '../lib/gitlab_reference_counter'
require_relative '../lib/gitlab_access'


# It's important that on pre-receive `increase_reference_counter` gets executed
# last so that it only runs if everything else succeeded. On post-receive on the
# other hand, we run GitlabPostReceive first because the push is already done
# and we don't want to skip it if the custom hook fails.
if GitlabAccess.new(gl_repository, repo_path, key_id, refs, protocol).exec &&
    GitlabCustomHook.new(repo_path, key_id).pre_receive(refs) &&
    GitlabReferenceCounter.new(repo_path).increase

  exit 0
else
  exit 1
end

为什么我无法加载.py文件?

Why I can`t able to load the .py file?

This basic snippet from Kernel#require should probably sum it up for you:

如果文件名具有扩展名".rb"，则将其作为源文件加载；如果扩展名是".so"，.o"或".dll"或当前平台上的默认共享库扩展名，则Ruby将共享库作为Ruby扩展名加载.否则，Ruby会尝试在名称中添加".rb"，.so"等，直到找到为止.如果找不到名为的文件，则会引发LoadError.

If the filename has the extension ".rb", it is loaded as a source file; if the extension is ".so", ".o", or ".dll", or the default shared library extension on the current platform, Ruby loads the shared library as a Ruby extension. Otherwise, Ruby tries adding ".rb", ".so", and so on to the name until found. If the file named cannot be found, a LoadError will be raised.
