This makes it possible to avoid N+1 queries when loading pipelines
table.
|
|
|
|
When displaying a project's pipelines
(Projects::PipelinesController#index) we now exclude the coverage data.
This data was not used by the frontend, yet getting it would require one
SQL query per pipeline. These queries in turn could be quite expensive
on GitLab.com.
|
|
When displaying the pipelines of a project we now preload the following
data:
1. Authors of the commits that belong to these pipelines
2. The number of warnings per pipeline, which is used by
Ci::Pipeline#has_warnings?
== Commit Authors
Previously this data was queried for every Commit separately, leading to
20 SQL queries being executed in the worst case. With an average of 3 to
5 milliseconds per SQL query this could result in 100 milliseconds being
spent in _just_ getting Commit authors.
To preload this data Commit#author now uses BatchLoader (through
Commit#lazy_author), and a separate module
Gitlab::Ci::Pipeline::Preloader is used to ensure all authors are loaded
before they are used.
== Number of warnings
This changes Ci::Pipeline#has_warnings? so it supports preloading of the
number of warnings per pipeline. This removes the need for executing a
COUNT(*) query for every pipeline just to see if it has any warnings or
not.

When displaying the project pipelines dashboard we display a few tabs
for different pipeline states. For every such tab we count the number of
pipelines that belong to it. For large projects such as GitLab CE this
means having to count over 80 000 rows, which can easily take between 70
and 100 milliseconds per query.
To improve this we apply a technique we already use for search results:
we limit the number of rows to count. The current limit is 1000, which
means that if more than 1000 rows are present for a state we will show
"1000+" instead of the exact number. The SQL queries used for this
perform much better than a regular COUNT, even when a project has a lot
of pipelines.
Prior to these changes we would end up running a query like this:
SELECT COUNT(*)
FROM ci_pipelines
WHERE project_id = 13083
AND status IN ('success', 'failed', 'canceled')
This would produce a plan along the lines of the following:
Aggregate (cost=3147.55..3147.56 rows=1 width=8) (actual time=501.413..501.413 rows=1 loops=1)
Buffers: shared hit=17116 read=861 dirtied=2
-> Index Only Scan using index_ci_pipelines_on_project_id_and_ref_and_status_and_id on ci_pipelines (cost=0.56..2984.14 rows=65364 width=0) (actual time=0.095..490.263 rows=80388 loops=1)
Index Cond: (project_id = 13083)
Filter: ((status)::text = ANY ('{success,failed,canceled}'::text[]))
Rows Removed by Filter: 2894
Heap Fetches: 353
Buffers: shared hit=17116 read=861 dirtied=2
Planning time: 1.409 ms
Execution time: 501.519 ms
Using the LIMIT count technique we instead run the following query:
SELECT COUNT(*)
FROM (
SELECT 1
FROM ci_pipelines
WHERE project_id = 13083
AND status IN ('success', 'failed', 'canceled')
LIMIT 1001
) for_count
This query produces the following plan:
Aggregate (cost=58.77..58.78 rows=1 width=8) (actual time=1.726..1.727 rows=1 loops=1)
Buffers: shared hit=169 read=15
-> Limit (cost=0.56..46.25 rows=1001 width=4) (actual time=0.164..1.570 rows=1001 loops=1)
Buffers: shared hit=169 read=15
-> Index Only Scan using index_ci_pipelines_on_project_id_and_ref_and_status_and_id on ci_pipelines (cost=0.56..2984.14 rows=65364 width=4) (actual time=0.162..1.426 rows=1001 loops=1)
Index Cond: (project_id = 13083)
Filter: ((status)::text = ANY ('{success,failed,canceled}'::text[]))
Rows Removed by Filter: 9
Heap Fetches: 10
Buffers: shared hit=169 read=15
Planning time: 1.832 ms
Execution time: 1.821 ms
While this query still uses a Filter for the "status" field the number
of rows that it may end up filtering (at most 1001) is small enough that
an additional index does not appear to be necessary at this time.

This ensures that we have more visibility in the number of SQL queries
that are executed in web requests. The current threshold is hardcoded to
100 as we will rarely (maybe once or twice) change it.
In production and development we use Sentry if enabled, in the test
environment we raise an error. This feature is also only enabled in
production/staging when running on GitLab.com as it's not very useful to
other users.

Uses `list_commits_by_oid` on the CommitService, to request the needed
commits for pipelines. These commits are needed to display the user that
created the commit and the commit title.
This includes fixes for tests failing that depended on the commit
being `nil`. However, now these are batch loaded, this doesn't happen
anymore and the commits are an instance of BatchLoader.

Being the good boyscouts, but mainly because of [the comment in the
review](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/12378#note_33302115)
the words used for classes and variables are changed to not use builds
anymore.

Achieved by using another table, which both has better indexes and
is smaller. Now the data provided for the user is more valueable too.
