From 38ecf75244c4cab93ecb201afff8980c29f56ce8 Mon Sep 17 00:00:00 2001 From: Ben Keene Date: Fri, 14 Feb 2020 14:44:45 +0000 Subject: [PATCH] git-p4: add p4 submit hooks The git command "commit" supports a number of hooks that support changing the behavior of the commit command. The git-p4.py program only has one existing hook, "p4-pre-submit". This command occurs early in the process. There are no hooks in the process flow for modifying the P4 changelist text programmatically. Adds 3 new hooks to git-p4.py to the submit option. The new hooks are: * p4-prepare-changelist - Execute this hook after the changelist file has been created. The hook will be executed even if the --prepare-p4-only option is set. This hook ignores the --no-verify option in keeping with the existing behavior of git commit. * p4-changelist - Execute this hook after the user has edited the changelist. Do not execute this hook if the user has selected the --prepare-p4-only option. This hook will honor the --no-verify, following the conventions of git commit. * p4-post-changelist - Execute this hook after the P4 submission process has completed successfully. This hook takes no parameters and is executed regardless of the --no-verify option. It's return value will not be checked. The calls to the new hooks: p4-prepare-changelist, p4-changelist, and p4-post-changelist should all be called inside the try-finally block.
