I used the stash git with this PR and some monkey patches.

Neither 'pass' nor 'try/except:pass' can truly exit the executing script.

print('This should be shown.')
try:
    sys.exit()
except:
    pass
print('This should NOT be shown')

@DavinE
I found a way to make the sys.exit work like old version.

In pythonista 3.4, there is a new script named pykit_startup.py that override the sys.exit method to avoid app really exit, and backup it to sys._exit .
So, you can just restore sys.exit to make it work as before.
Add these codes before your main entry:

import sys
sys.exit = sys._exit

@BSoD
Finally, I made it work correctly.

When I used STASH's GIT, after a bunch of code adjustments, it finally raised this error.

Although I am not sure, under Pythonista 3.3, it is possible to run STASH with Python 3 and use a modified version of GIT. Therefore, there should have been no unsupported issue in the past.

Actually, I don't really care about this issue.
I am just looking for a GIT that supports SSH and can be used in Pythonista 3.4 .

@DavinE
No.
But this error only occurs at the end of the program and has no actual impact.
So, until the official fixes this issue, you can temporarily ignore this error.

@DavinE
Me too.
sys.exit() always raise the key interrupt error.
