From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx>
Append more testcases in t1416 for various git commands that may trigger
the "reference-transaction" hook.
In order to create a common "reference-transaction" hook, we define the
common hook path using config variable "core.hooksPath", and create the
"reference-transaction" hook in the path.
Some commands trigger the "reference-transaction" hook properly and get
the expected output. E.g.:
* git branch <new-branch> <oid> # create new branch
* git clone
* git commit [--amend]
* git fetch
* git merge
* git push [--atomic]
* git reset --hard
* git tag [-f] <tag> <oid> # update tag
* git tag <new-tag> <oid> # create new tag
* git update-ref --stdin # create new refs
* git update-ref <ref> <oid> # create new ref
* git update-ref <ref> <new-oid> <old-oid> # update ref
But 17 testcases failed.
Some commands failed because the expected "<old-oid>" became
"<zero-oid>". E.g.:
* git branch [-f] <ref> <new-oid> # update branch
* git cherry-pick <oid>
* git rebase
* git tag -d <tag>
* git update-ref --stdin # update/delete refs
* git update-ref -d <ref>
* git update-ref <ref> <new-oid> # update ref
Some commands failed because the "reference-transaction committed"
command was repeated multiple times for the same changes. E.g.:
* git cherry-pick
* git rebase
* git revert
* git tag -d <tag>
* git update-ref -d <ref>
* git update-ref --stdin # delete refs
Some commands should not trigger the "reference-transaction" hook
because no real changes have occurred to the repository. E.g.:
* git gc
* git pack-refs --all
Some commands did not execute the "reference-transaction" hook at all.
E.g.:
* git branch -c <src> <dest> # copy branch
* git branch -m <old> <new> # rename branch
Some commands ran unexpected command "reference-transaction aborted".
E.g.:
* git branch -d <branch> # delete branch
* git branch -m <old> <new> # rename branch
* git cherr-pick <oid>
* git rebase
* git revert
* git tag -d <tag> # delete tag
* git update-ref -d <ref> # delete ref
We will fix the failed testcases in later commits.
