If a repository has
git config --add push.pushOption submit=".sourcehut/*.yml"
it failed when pushed because of the unknown submit push
option. It will be ignored instead.
Filtering out the push options is done in an earlier stage, when the
hook command runs, before it submits the options map to the private
endpoint.
* move all the push options logic to modules/git/pushoptions
* add 100% test coverage for modules/git/pushoptions
Test coverage for the code paths from which code was moved to the
modules/git/pushoptions package:
* cmd/hook.go:runHookPreReceive
* routers/private/hook_pre_receive.go:validatePushOptions
tests/integration/git_push_test.go:TestOptionsGitPush runs through
both. The test verifying the option is rejected was removed and, if
added again, will fail because the option is now ignored instead of
being rejected.
* cmd/hook.go:runHookProcReceive
* services/agit/agit.go:ProcReceive
tests/integration/git_test.go: doCreateAgitFlowPull runs through
both. It uses variations of AGit related push options.
* cmd/hook.go:runHookPostReceive
* routers/private/hook_post_receive.go:HookPostReceive
tests/integration/git_test.go:doPushCreate called by TestGit/HTTP/sha1/PushCreate
runs through both.
Note that although it provides coverage for this code path it does not use push options.
