If the source import directory were different from the destination directory,
GitLab would first create a blank repository and then erroneously move the
original one into a subdirectory. Adding an import type prevents this the project
from being initialized in the first place. It was accidentally removed in
1f917cbd49.

Fix invalid pipeline build chain tag evaluation

Closes #40944

See merge request gitlab-org/gitlab-ce!15805

TableOfContents filter generates hrefs for each header in markdown,
if the header text consists from digits and redacted symbols only,
e.g. "123" or "1.0 then the auto-generated href has the same format
as issue references.

If the generated id contains only digits, then 'anchor-' prefix is
prepended to the id.

Closes #38473

Merge branch '29483-no-feedback-when-checking-on-checklist-if-potential-spam-was-detected' into 'master'

Resolve "No feedback when checking on checklist if potential spam was detected"

Closes #29483

See merge request gitlab-org/gitlab-ce!15408

When displaying events we would load the target of those events, then
render the entire data using our Markdown pipeline. This pipeline would
eventually request the author of every target, leading to an additional
query being executed for every target to get the author.

To fix this we now eager load the author of the event's target. In my
local environment this reduces the number of queries to display a
project's Atom feed from 40 to 24 queries.

Check NFS mounts in a separate process

Closes #39847

See merge request gitlab-org/gitlab-ce!15426

Moving the check out of the general requests, makes sure we don't have
any slowdown in the regular requests.

To keep the process performing this checks small, the check is still
performed inside a unicorn. But that is called from a process running
on the same server.

Because the checks are now done outside normal request, we can have a
simpler failure strategy:

The check is now performed in the background every
`circuitbreaker_check_interval`. Failures are logged in redis. The
failures are reset when the check succeeds. Per check we will try
`circuitbreaker_access_retries` times within
`circuitbreaker_storage_timeout` seconds.

When the number of failures exceeds
`circuitbreaker_failure_count_threshold`, we will block access to the
storage.

After `failure_reset_time` of no checks, we will clear the stored
failures. This could happen when the process that performs the checks
is not running.

create_merge_request_handler_spec needs a repository for some tests but
this repository lasts on disk by default which causes failures of other
tests. TestEnv.clean_test_path is used to get rid of the repository
after each test.
