This returns a Server-Timing header on all HTTP responses, which
includes details on how long it took the server to render the response.
Browsers can show this timing information in the devtools. In Chrome, go
to the Network panel, then click a HTTP request, then click the Timing tab.
* Update framework files with `bin/rails app:update`.
* Update to use new Rails 7.0 default settings, except for a couple
things regarding new cookie and cache formats that would prevent us
from rolling back to Rails 6.1 if necessary.
Fix the paginator not detecting the first or last page correctly during
sequential pagination.
Caused by the fact that we fetch one more record than needed to detect
whether we're on the last page, then throw that record away by
overriding Rails' internal `records` method. An upstream refactoring
meant that the `size` method now counts the number of records *after*
the extra record is thrown away, where before it counted *before* the
extra record was thrown away.
Previously we overrode `ActiveRecord::Base#columns` to make it ignore
tsvector columns so they wouldn't show up in API responses. These
columns have been removed, so this is no longer necessary.
is_note_locked, is_rating_locked, and is_status_locked have been unused
since 126046cb6.
tag_index has been unused since 37a8dc5db.
fav_string has been unused since 165339236.
pool_string has been unused since 7d503f088.
Fix a bug where /jobs?search[name]=Prune+Posts didn't find jobs named PrunePostsJob.
`"Prune Posts".tr(" ", "_").classify` was wrong because it returned `"PrunePost"`.
Fix an `ActionView::Template::Error: undefined method 'verification_key'
for nil` error in the welcome_user mailer when a user signs up without
an email address.
Caused by the fact that we now render mail templates regardless of
whether the user has an email address, and then skip sending the email
only after the mail template is rendered.
Fix the /jobs listing to show retried jobs. GoodJob::ActiveJobJob has a
default scope that filters out retried jobs; remove it in the index
controller so we can see retried jobs.
Also fix mail delivery jobs not showing up in the dropdown in the /jobs
search form.
Add ability to search jobs on the /jobs page by job type or by status.
Fixes#2577 (Search filters for delayed jobs). This wasn't possible
before with DelayedJobs because it stored the job data in a YAML string,
which made it difficult to search jobs by type. GoodJobs stores job data
in a JSON object, which is easier to search in Postgres.
Remove the DelayedJobs gem and database table. Completes the transition
to GoodJob started in c06bfa64f and f4953549a.
Downstream users can upgrade as follows:
* Stop the Rails server.
* Stop the DelayedJobs worker (normally running as `bin/delayed_job` or `bin/rails jobs:work`).
* Run `bin/rails jobs:work` to finish any pending delayed jobs.
* Run `bin/rails db:migrate` to create the good_jobs table and drop the delayed_jobs table.
* Start the Rails server again.
* Start the GoodJobs worker with `bin/good_job start`.
Switch the ActiveJob backend from DelayedJob to GoodJob. Differences:
* The job worker is run with `bin/good_job start` instead of `bin/delayed_job`.
* Jobs have an 8 hour timeout instead of a 4 hour timeout.
* Jobs don't automatically retry on failure.
* Finishing jobs are preserved and pruned after 7 days.
This is the first step towards replacing DelayedJob with GoodJob. Compared to
DelayedJob:
* GoodJob supports Rails 7 (DelayedJob is currently a blocker for Rails 7
because it has a version bound on ActiveRecord <6.2).
* GoodJob has a builtin admin dashboard.
* GoodJob supports threaded job workers.
* GoodJob supports scheduled cronjobs.
* GoodJob supports healthchecks for workers.
* GoodJob uses Postgres notifications instead of polling to pick up new
jobs. This allows jobs to be picked up faster and scales better with
large numbers of workers.

Fix an `undefined method 'find' for Maintenance::User:Module` exception
when disabling email notifications using the "Disable notifications"
link in dmails.
Add a fix script to fix email addresses that are invalid or that contain
common typos. If the email can't be fixed, usually because the fixed
address is already in use by another account, then the email address is
marked undeliverable.
Fix mailers to not attempt deliveries to invalid or nonexistent email
addresses. This usually happened when someone changed their email, and
we tried to send a confirmation email to a nonexistent address.
Fix an exception when checking out on Stripe caused by using the
`allow_promotion_codes` and `discounts` parameters at the same time.
Stripe::InvalidRequestError - You may only specify one of these parameters: allow_promotion_codes, discounts
Switch the Ruby memory allocator from Glibc malloc to Jemalloc. Jemalloc
supposedly uses less memory than Glibc malloc because it's better at
handling memory fragmentation. It also has detailed internal statistics
to help monitor allocator behavior.
We use the LD_PRELOAD method of loading Jemalloc instead of building it
into Ruby so that we can switch allocators at runtime.
Further micro-optimize thumbnails to reduce string allocations.
`Post#levelblocked?` gets called once per thumbnail. Before it split the
tag string, which meant one string allocation for each tag on each post.
This added up to thousands of string allocations per pageload.
