* Make IdsToBigints (mostly!) non-blocking
This pulls in GitLab's MigrationHelpers, which include code to make
column changes in ways that Postgres can do without locking. In general,
this involves creating a new column, adding an index and any foreign
keys as appropriate, adding a trigger to keep it populated alongside
the old column, and then progressively copying data over to the new
column, before removing the old column and replacing it with the new
one.
A few changes to GitLab's MigrationHelpers were necessary:
* Some changes were made to remove dependencies on other GitLab code.
* We explicitly wait for index creation before forging ahead on column
replacements.
* We use different temporary column names, to avoid running into index
name length limits.
* We rename the generated indices back to what they "should" be after
replacing columns.
* We rename the generated foreign keys to use the new column names when
we had to create them. (This allows the migration to be rolled back
without incident.)
# Big Scary Warning
There are two things here that may trip up large instances:
1. The change for tables' "id" columns is not concurrent. In
particular, the stream_entries table may be big, and does not
concurrently migrate its id column. (On the other hand, x_id type
columns are all concurrent.)
2. This migration will take a long time to run, *but it should not
lock tables during that time* (with the exception of the "id"
columns as described above). That means this should probably be run
in `screen` or some other session that can be run for a long time.
Notably, the migration will take *longer* than it would without
these changes, but the website will still be responsive during that
time.
These changes were tested on a relatively large statuses table (256k
entries), and the service remained responsive during the migration.
Migrations both forward and backward were tested.
* Rubocop fixes
* MigrationHelpers: Support ID columns in some cases
This doesn't work in cases where the ID column is referred to as a
foreign key by another table.
* MigrationHelpers: support foreign keys for ID cols
Note that this does not yet support foreign keys on non-primary-key
columns, but Mastodon also doesn't yet have any that we've needed to
migrate.
This means we can perform fully "concurrent" migrations to change ID
column types, and the IdsToBigints migration can happen with effectively
no downtime. (A few operations require a transaction, such as renaming
columns or deleting them, but these transactions should not block for
noticeable amounts of time.)
The algorithm for generating foreign key names has changed with this,
and therefore all of those changed in schema.rb.
* Provide status, allow for interruptions
The MigrationHelpers now allow restarting the rename of a column if it
was interrupted, by removing the old "new column" and re-starting the
process.
Along with this, they now provide status updates on the changes which
are happening, as well as indications about when the changes can be
safely interrupted (when there are at least 10 seconds estimated to be
left before copying data is complete).
The IdsToBigints migration now also sorts the columns it migrates by
size, starting with the largest tables. This should provide
administrators a worst-case scenario estimate for the length of
migrations: each successive change will get faster, giving admins a
chance to abort early on if they need to run the migration later. The
idea is that this does not force them to try to time interruptions
between smaller migrations.
* Fix column sorting in IdsToBigints
Not a significant change, but it impacts the order of columns in the
database and db/schema.rb.
* Actually pause before IdsToBigints

- 500.html generated with admin-set default locale if set
- Error page `<title>` includes Mastodon site title
- 500 title changed to "This page is not
correct" (ref: <https://www.youtube.com/watch?v=2VCAP_seh1A>)
- 500 content appended with "on our end" to make clear it's
not user's fault

A new rake task emojis:generate downloads a full list of valid
unicode sequences from unicode.org and checks it against existing
Twemoji files, finally generating a map from each sequence to the
existing file (e.g. when there's multiple ways an emoji can be
expressed). The map is dumped into app/javascript/mastodon/emoji_map.json
That file is loaded by emojione_light.js (now a misnomer) which
decorates it further with shortcodes taken from emoji-mart's index.

They are marked as read-only by Rails, but we know what we are doing,
so we are un-marking them as such.
The mastodon:maintenance:update_counter_caches task is not really
supposed to be run anymore (it was a one-time thing during an upgrade)
however, just in case, I have modified it to not touch ActivityPub
accounts.
Also, no point writing to logger from these rake tasks, since they
are not to be run from cron. Better to give stdout feedback.

* Use casecmp() instead of casecmp?() for now
casecmp?() is only available in ruby 2.4.0. Users running earlier ruby versions
would see errors, e.g., running
RAILS_ENV=production rails mastodon:maintenance:remove_deprecated_preview_cards.
* Correctly check whether casecmp() returns 0

The path template of the attached files must explicitly be defined because
it is contradicting to the name of the class.

Because Nanobox doesn't run data components in the same container as the code, there are a few tweaks that need to be made in the configuration to get WebPack to work properly in development mode.
The same differences lead to needing to use `DATABASE_URL` by default in the `.env` file for Rails to work correctly.
Limitations of our `.env` loader for Node.js mean the `.env` file needs to be compiled everywhere in order to work, so we compile it in development, now, too. Also, all the `.env.production` tweaks have been consolidated into a single command.
Finally, since Nanobox actually creates the database when it sets up the database server, using the existence of the database alone to determine whether to migrate or setup is insufficient. So we add a condition to `rake db:migrate:setup` to check whether any migrations have run - if the database doesn't exist yet, `db:setup` will be called; if it does, but no migrations have been run, `db:migrate` and `db:seed` are called instead (the same basic idea as what `db:setup` does, but it skips `db:create`, which will only cause problems with an existing DB); otherwise, only `db:migrate` is called.
None of these changes should affect development, and all are designed not to interfere with existing behaviors in other environments.
