This adds a method to track errors that can be recovered from in
sentry.

It is useful when debugging performance issues, or exceptions that are
hard to reproduce.

Closes #45412

This is useful for a transition period to migrate away from
`NoninternalAtomicId`. In a situation where both the old and new code to
generate a iid value is run at the same time (for example, during a
deploy different nodes may serve both versions), this will lead to
problems regarding the correct `last_value`. That is, what we track in
`InternalId` may get out of sync with the maximum iid present for
issues.

With this change, we double-check that and correct the `last_value` with
the maximum iid found in issues if necessary.

This is subject to be removed with the 10.8 release and tracked over
here: https://gitlab.com/gitlab-org/gitlab-ce/issues/45389

Closes #45269.

This is called repeatedly when viewing a merge request, and this should
improve performance significantly by avoiding shelling out to git every time.

This should help https://gitlab.com/gitlab-com/infrastructure/issues/4027.

There are 2 problems with this spec:

1. It checks for default visiblity level however there is not code in
controller to handle such default. Same check can be performed on model
directly.
2. It passes empty application_setting hash while controller requires
application_setting not to be empty by using `require` with `permit`

Closes #45247.

If form does not have import sources checkboxes we should not reset
import sources to empty. This fixes issue when import sources got reset
after user modifies unrelated settings section like GitLab pages

Closes #45326

Since !18150 abstract reference filter supports also `group`
as a resource parent (not only `project`). Some reference filters,
which inherit from abstract filter, depend on parent being `project`
when checking a reference.

This patch adds explicit check of parent class to the given filters.

Fixes gitaly#1126
