Python Git Bash CMD Script

Question

The code is pretty straightforward, it just opens windows command prompt and executes the calling() function. It has basic git commands which help me push to a git repo. I have configured ssh and remote repo.

Link:https://github.com/vivekpatani/git-script-gitter

I can change the date, but when I push it to git, it displays the current date on which I pushed rather than the one I committed.

The Commit List where it shows committed 9 days ago and 11 days ago, I want it to actually show the same date as committed.

def calling():

    #Simply opening command prompt in Windows
    subprocess.call("git --version")
    subprocess.call("git status")
    subprocess.call("git add .")
    subprocess.call("git commit -am \"Changing Things\" --date=\"Sat, 26 Mar 2016 18:46:44 -0800\"")
    subprocess.call("git push origin master")

    #To stop from cmd closing automatically
    temp = input("Enter to close:")

def main():
     calling()

if __name__ == "__main__":
    main()

After looking around I read that I need to change the AUTHOR DATE and COMMIT DATE together? Can somebody please help me out.

EDIT 1: I'm working on Windows OS.

It works when I run it through Git Bash, somehow just need to convert that to Python.

git --version
git status
git add .
GIT_AUTHOR_DATE='Fri Mar 25 19:32:10 2016 -0800' GIT_COMMITTER_DATE='Fri Mar 25 19:32:10 2016 -0800' git commit -am "Hello Laney"
git push origin master

EDIT 2: Solution

def calling(git_date):
    subprocess.call("git --version")
    subprocess.call("git status")
    subprocess.call("git add .")

    #The next statement is important as updates/adds new GitCommiterDate in environment making it the current commit date.
    os.environ["GIT_COMMITTER_DATE"] = 'Fri Mar 25 19:32:10 2016 -0800'

    #The date in commit command only changes author date.
    subprocess.call("git commit -am \"Changing Things\" --date=\"Fri Mar 25 19:32:10 2016 -0800\"")
    subprocess.call("git push origin master")

--date only modifies the author date.

You need to set GIT_COMMITTER_DATE environment variable in order to have the same date as author date (using the env option of Popen(), and merging it with the current environment).

subprocess.call("git commit -am \"Changing Things\" --date=\"Sat, 26 Mar 2016 18:46:44 -0800\"", env=dict(os.environ, "GIT_COMMITTER_DATE":"Sat, 26 Mar 2016 18:46:44 -0800"))

Thanks, but when I print os.environ, I cannot find the GIT_COMMITTER_DATE. Also the line contains a syntax issue. Please could you guide me? – Viv Mar 28 '16 at 16:12

@VivekPatani the goal is to *add* that variable to the environment variables, not to find it. – VonC Mar 28 '16 at 16:13
@VivekPatani Also, a double-quote was missing. – VonC Mar 28 '16 at 16:13
I just made a few changes to what you said. The answer you mentioned is correct, but since it was still giving issues, I just split the commands into two parts. os.environ["GIT_COMMITTER_DATE"] = "Fri, 25 Mar 2016 18:46:44 -0800" and then subprocess.call("git commit -am \"Changing Things\" --date=\"Fri, 25 Mar 2016 18:46:44 -0800\"") – Viv Mar 28 '16 at 16:32

@VivekPatani Great! Don't hesitate to edit this answer. – VonC Mar 28 '16 at 16:33
