How to get SHA of commit for Xcode Bot "Run Script" Trigger? Updating status of tests on Github

I am using this code in my Xcode Bot triggers to get the SHA of the commit:

git -C ${XCS_SOURCE_DIR}/name_of_your_git_repo rev-parse HEAD

And this to get the branch name:

git -C ${XCS_SOURCE_DIR}/name_of_your_git_repo rev-parse --abbrev-ref HEAD

This executes a git command in the source directory, replace "name_of_your_git_repo" by the name of your repository on git

XCS_OUTPUT_DIR has a file called sourceControl.log. This file has logs like the following:

"DVTSourceControlLocationRevisionKey" : "3787c0d9e5107861a8b8d4c7300b2d414ad41dbb",

You can parse that log to find the SHA.

Perhaps more practically, CaveJohnson can pull the SHA:

PATH=/Library/Frameworks/Python.framework/Versions/3.4/bin:$PATHSHA=`cavejohnson getSha`

Or it can just go ahead and set the GitHub status as a one-liner:

#!/bin/bashPATH=/Library/Frameworks/Python.framework/Versions/3.4/bin:$PATHcavejohnson setGithubStatus

Notably, there are more statuses than just success and failure, there are at least 6 that I'm aware of. You can read more about them in my Xcode 6 CI Missing Manual.

Using the cavejohnson code in the other answer, which gets the hash from certain keys an Xcode log, I ran into an issue where the returned hash was an outdated one from the last build.

I'm now instead using git rev-parse HEAD to get the hash of the commit that was actually used in the CI build. I've submitted this as a revision to cavejohnson.

Use get_sha() to retrieve the SHA-1 hash:

def get_sha():    return get_repo_sha(get_git_directory())def get_git_directory():    for subdir in os.listdir('.'):        if is_git_directory(subdir):            return subdir    assert Falsedef is_git_directory(path = '.'):    return subprocess.call(['git', '-C', path, 'status'], stderr=subprocess.STDOUT, stdout = open(os.devnull, 'w')) == 0    def get_repo_sha(repo):    sha = subprocess.check_output(['git', 'rev-parse', 'HEAD'], cwd=repo).decode('ascii').strip()    return sha
