Subject: [PATCH 0/5] Maintenance: adapt custom refspecs
Date: Mon, 05 Apr 2021 13:04:10 +0000 [thread overview]
Message-ID: <pull.924.git.1617627856.gitgitgadget@gmail.com> (raw)
Tom Saeger rightly pointed out [1] that the prefetch task ignores custom
refspecs. This can lead to downloading more data than requested, and it
doesn't even help the future foreground fetches that use that custom
refspec.

This series fixes this problem by carefully replacing the start of each
refspec's destination with "refs/prefetch/". If the destination already
starts with "refs/", then that is replaced. Otherwise "refs/prefetch/" is
just prepended.
In order to accomplish this safely, a new refspec_item_format() method is
created and tested.
Patch 1 is just a preparation patch that makes the code simpler (and in
hindsight it should have been written this way from the start).
Patch 2 is a simplification of test_subcommand that removes the need for
escaping glob characters. Thanks, Eric Sunshine, for the tip of why my tests
were failing on FreeBSD.
Patches 3-4 add refspec_item_format().
Patch 5 finally modifies the logic in the prefetch task to translate these
refspecs.
Thanks, -Stolee

maintenance: simplify prefetch logic
test-lib: use exact match for test_subcommand
refspec: output a refspec item
test-tool: test refspec input/output
maintenance: allow custom refspecs during prefetch
