This sets up all the basics for importing Phabricator tasks into
GitLab issues.
To import all tasks from a Phabricator instance into GitLab, we'll
import all of them into a new project that will have its repository
disabled.
The import is hooked into a regular ProjectImport setup, but similar
to the GitHub parallel importer takes care of all the imports itself.
In this iteration, we're importing each page of tasks in a separate
sidekiq job.
The first thing we do when requesting a new page of tasks is schedule
the next page to be imported. But to avoid deadlocks, we only allow a
single job per worker type to run at the same time.
For now we're only importing basic Issue information, this should be
extended to richer information.
Issues and merge requests imported from GitHub are having state_id
set to null. This fixes the GitHub project importer and schedule
migrations to fix state_id.
After an initial fetch, the repository will have many loose objects
and refs. Running a `git gc` will compact refs into `packed-refs` and
objects into `.pack` files, which should make importing pull
requests faster.
Part of https://gitlab.com/gitlab-org/gitlab-ce/issues/59477
When the GitHub importer creates a merge request, it retrieves the SHA
but does not actually create the source branch. This makes it impossible
to merge an open merge request, particularly if the source branch were
from a forked project. In that case, the branch will never exist because
the original `project-name:source-branch` name is never created, nor
is it a valid branch name.
To prevent possible branch name conflicts, forked source branches
are now renamed `github/fork/project-name/source-branch` and created
when necessary.
Note that we only create the source branch if the merge request
is open. For projects that have many merge requests, the project
would end up with a lot of possibly dead branches.
