This backports all EE schema changes to CE, including EE migrations,
ensuring both use the same schema.
== Updated tests
A spec related to ghost and support bot users had to be modified to make
it pass. The spec in question assumes that the "support_bot" column
exists when defining the spec. In the single codebase setup this is not
the case, as the column is backported in a later migration. Any attempt
to use a different schema version or use of "around" blocks to
conditionally disable specs won't help, as reverting the backport
migration would also drop the "support_bot" column. Removing the
"support_bot" tests entirely appears to be the only solution.
We also need to update some foreign key tests now that we have
backported the EE columns. Fortunately, these changes are very minor.
== Backporting migrations
This commit moves EE specific migrations (except those for the Geo
tracking database) and related files to CE, and also removes any traces
of the ee/db directory.
Some migrations had to be modified or removed, as they no longer work
with the schema being backported. These migrations were all quite old,
so we opted for removing them where modifying them would take too much
time and effort.
Some old migrations were modified in EE, while also existing in CE. In
these cases we took the EE code, and in one case removed them entirely.
It's not worth spending time trying to merge these changes somehow as we
plan to remove old migrations around the release of 12.0, see
https://gitlab.com/gitlab-org/gitlab-ce/issues/59177 for more details.
Correct the ordering of metrics on performance dashboard. Before common
metrics were moved into the DB, metric groups were ordered by the
priority defined in the common_metrics.yml file.
This commit adds a priority to each metric group in the PrometheusMetric
model.
It also combines title, priority and required_metrics into one frozen
GROUP_DETAILS hash so that the code is clearer.
This can be done since there is a fixed set of groups which are not
configurable.
This is useful for when runner is bundled with gitlab, like in a kubernetes stack, and we want the runner to be able to
register with gitlab as soon as they both come up.
