Similar to https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/31834,
we see that in https://gitlab.com/gitlab-org/gitlab-ce/issues/65957
there can be hundreds, even thousands, of Gitaly requests in the
`/api/:version/projects/:id/merge_requests/:noteable_id/notes` endpoint.
Previously, the API to retrieve notes generated hundreds of Gitaly calls
to determine whether a system note should be shown to the user. It did
this by:
1. Rendering the Markdown
2. Extracting cross-references from the Markdown
3. Issuing a Gitaly `FindCommit` RPC for every reference to validate
that the commit exists.
The last step is unnecessary because we don't need to display a commit
if the user doesn't have access to the project in the first place.
`RendersNotes#prepare_notes_for_rendering` is already used in
`MergeRequestsController`, which is why we don't see N+1 Gitaly calls
there. We use it here to optimize the note redaction process.
Remove project from NotesFinder constructor
Add project parameter to specs
Also look for methods in private scope
Fix specs to match new NotesFinder constructor
Fix missing iid query on NotesFinder
Changed parameters of find_noteable,
so changes across a few files were needed.
MergeRequest also requires iid instead of id query
Make NotesFinder fail with RecordNotFound again
Add specs for target_iid
Using RSpec tablesyntax for target_iid specs
Revert "Using RSpec tablesyntax for target_iid specs"
This reverts commit ba45c7f569a.
Allow find_by! here
Fix variable name
Add readable check
Revert "Add readable check"
This reverts commit 9e3a1a7aa39.
Remove unnecessary assignment
Add required changes for EE
Fix parameter count
Reduce code duplication by extracting a noteable module method
The call to find_noteable was redundant so
multiple files and lines have changed in that
commit to use the newly introduced module
method `noteable`.
Replace casecmp with include check
Add parent_type parameter
Revert "Reduce code duplication by extracting
a noteable module method"
This reverts commit 8c0923babff16.
Method is no longer needed
Check whether noteable can be read by user
This replaces API::Notes::NOTEABLE_TYPES and
API::Discussions::NOTEABLE_TYPES with class methods defined in a
separate helper modules. This allows EE to extend the list of noteable
types, without having to modify the constant in-place. We can't define
these methods directly in the API classes, as they would be used before
we're able to extend them in EE.
* adds basic discussions API for issues and snippets
* reorganizes notes specs (so same tests can be used for all noteable types - issues, MRs, snippets)
