"Exception Cmd('git') failed due to:" - not trigegring try:except

[rusnackor]

Hello guys.

I am preparing scrip that is meant to pull/checkout more repositories in different directories.
However, soemtimes can happen this:

Exception Cmd('git') failed due to: exit code(1)
  cmdline: git pull -v origin
  stderr: 'error: Your local changes to the following files would be overwritten by merge:
        common_logic.py
        git_jobs.py
        svn_jobs.py
        test_updating.py
        updater.py
        updater_core.py
        updating_conf.py
        updating_consts.py
Please commit your changes or stash them before you merge.
Aborting'

But when I try to put my code into try:except block, like this:

import git

try:
    repo = git.Repo("/path/to/my/repo")
    o = repo.remotes.origin
    result = o.pull()
    for item in result:
        print("Item : {}".format(item))
except Exception as e:
    print("Exception {}".format(e))

Nothing changes, the script still throws exception and fails. Is it possible to cover this case, and make it not to crash?

PS: Is it possible to make it, that it does not ask me for credentials every time? (like put them inside of my code)

This would prevent the exception from stopping the program there, maybe there are other exceptions happening later due to the pull not being successful after all? Manually checking for this case would certainly be required to avoid exceptions.

There is some information about this in the Handling Remotes section of the docs.

No, there are no other exceptions, or at least, those are not visible:

my_user@my_pc: ~/my_dir/my_subdir $ python3 test_pull.py

my_user@my_pc: ~/my_dir/my_subdir $

I added debug prints after each line. The exception is exactly on pull.

    print(2)
    o = repo.remotes.origin
    print(3)
    #print(repo.untracked_files)
    print(4)
    result = o.pull()
    print(5)
    for item in result:

Interesting, I have no clue how a caught exception can still halt a python program.
