According to #33449 and #33468, cpu_time and allocations are 0 when
JRuby is used.

Only use CLOCK_PROCESS_CPUTIME_ID if it's defined

It's not defined on JRuby and unlike monotonic time, concurrent-ruby doesn't have an cross-platform abstraction for this.

The purpose of the module seems to quack like a string.

To make it easier to construct boundable predicate.

PDFPreviewer became MuPDFPreviewer in 0b717c2. Previewers are simple enough that we can just provide a single example.

The target object for counter cache is not always determined by the
primary key value on the model. I'd like to extract `update_couters`
onto the `Relation` for the internal use.

Ruby 2.4 has native `Regexp#match?`.

Enable regex cops

`5 =~ /\d/` returns nil, but Integer doesn't have a `match?` method.

Rubocop warns about "Use String#end_with? instead of a regex match anchored to the end of the string",
it doesn't seem aware of the $` special variable like Performance/RegexpMatch
|
|/
|
|
|
| |
In cases where the MatchData object is not used, this provides a speed-up:

* Select 'p' for "BASE TABLE" and add a test case
to support PostgreSQL 10 partition tables
* Address RuboCop offense
* Addressed incorrect `postgresql_version`
Fixes #33008.

PR#32381 added Rubocop's comments to some tests files in order to
exclude `Performance/RedundantMerge`.
Turn off `Performance` cops for tests files via `Exclude`

Add event object subscriptions to AS::Notifications
|
| | | |
|
| | | |
|
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
We don't need to have a special subscribe method for objects. The
regular `subscribe` method is more expensive than a specialized method,
but `subscribe` should not be called frequently. If that turns out to
be a hotspot, we can introduce a specialized method. :)

Fanout notifier can send event objects to subscribers now. Also moved
`end` lower in the `finish!` method to guarantee that CPU time is
shorter than real time.

* Use process clock instead of Time.now
This fixes any issues with the system clock changing and also eliminates
2 object allocations per event.
* Add start! and finish! methods to the event object so we can record
more information
* Adds cpu time, idle time, and allocation count for a particular event.

## Summary
RuboCop 0.58.2 was released.
https://github.com/rubocop-hq/rubocop/releases/tag/v0.58.2
And rubocop-0-58 channel is available in Code Climate.
https://github.com/codeclimate/codeclimate/releases/tag/v0.76.0
https://github.com/codeclimate/codeclimate/commit/38f21f0
In addition, the following changes are made in this PR.
- Replace Custom cops with Rails cops
- Add jaro_winkler gem to Gemfile.lock
### Replace Custom cops with Rails cops
These are compatible replacements.
- Replace `CustomCops/AssertNot` cop with `Rails/AssertNot` cop.
- Replace `CustomCops/RefuteNot` cop with `Rails/RefuteMethods` cop.
With this replacement, it was decided to use cop of RuboCop itself.
It removes the code related to CustomCops accordingly.
### Add jaro_winkler gem to Gemfile.lock
Since RuboCop 0.57.0 depends on jaro_winkler gem,
it has been added to Gemfile.lock.

Reference Active Storage instead of third-party libraries in guide

Paperclip has officially been deprecated, so we shouldn't mention it
anymore.
CarrierWave could still be referenced, as there are use cases where it
currently makes more sense, but for simplicity, I thought removing the
mention of third party libraries made sense. If we want to talk about
them, listing "alternatives" within the Active Storage guide could make
more sense.

method is 12% slower
Use flat_map over map.flatten(1)
flatten is 66% slower
Use hash[]= instead of hash.merge! with single arguments
merge! is 166% slower
