Subject: [RFC PATCH] branch: add "inherit" option for branch.autoSetupMerge
Date: Wed, 8 Sep 2021 13:15:45 -0700 [thread overview]
Message-ID: <9628d145881cb875f8e284967e10f587b9f686f9.1631126999.git.steadmon@google.com> (raw)
It can be helpful when creating a new branch to use the existing
tracking configuration from the branch point. However, there is
currently not a method to automatically do so.
Teach branch.autoSetupMerge a new "inherit" option. When this is set,
creating a new branch will cause the tracking configuration to default
to the configuration of the branch point, if set.
NEEDS WORK:
* this breaks `git checkout -b new-branch --recurse-submodules`
* add documentation
* add tests
* check corner cases, including whether this plays well with related
cmd-line options (switch, checkout, branch)

I'll be looking into the --recurse-submodules breakage today, and then
I'll work on polishing the patch after that's fixed. But I thought it's
worth getting an idea of how the list feels about the feature in general
while I sort through the issues.
