MergeRequests::PushOptionsHandlerService has been updated to allow
creating and updating merge requests with the
`merge_when_pipeline_succeeds` set using git push options.
To create a new merge request and set it to merge when the pipeline
succeeds:
git push -u origin -o merge_request.create \
-o merge_request.merge_when_pipeline_succeeds
To update an existing merge request and set it to merge when the
pipeline succeeds:
git push -u origin -o merge_request.merge_when_pipeline_succeeds
Issue https://gitlab.com/gitlab-org/gitlab-ce/issues/53198
Previously the raw push option Array was sent to Pipeline::Chain::Skip.
This commit updates this class (and the chain of classes that pass the
push option parameters from the API internal `post_receive` endpoint to
that class) to treat push options as a Hash of options parsed by
GitLab::PushOptions.
The GitLab::PushOptions class takes options like this:
-o ci.skip -o merge_request.create -o merge_request.target=branch
and turns them into a Hash like this:
{
ci: {
skip: true
},
merge_request: {
create: true,
target: 'branch'
}
}
This now how Pipeline::Chain::Skip is determining if the `ci.skip` push
option was used.
To create a new merge request:
git push -u origin -o merge_request.create
To create a new merge request setting target branch:
git push -u origin -o merge_request.create \
-o merge_request.target=123
To update an existing merge request with a new target branch:
git push -u origin -o merge_request.target=123
A new Gitlab::PushOptions class handles parsing and validating the push
options array. This can be the start of the standard of GitLab accepting
push options that follow namespacing rules. Rules are discussed in issue
https://gitlab.com/gitlab-org/gitlab-ce/issues/43263.
E.g. these push options:
-o merge_request.create -o merge_request.target=123
Become parsed as:
{
merge_request: {
create: true,
target: '123',
}
}
And are fetched with the class via:
push_options.get(:merge_request)
push_options.get(:merge_request, :create)
push_options.get(:merge_request, :target)
A new MergeRequests::PushOptionsHandlerService takes the `merge_request`
namespaced push options and handles creating and updating
merge requests.
Any errors encountered are passed to the existing `output` Hash in
Api::Internal's `post_receive` endpoint, and passed to gitlab-shell
where they're output to the user.
