This timestamp is to track the last refreshlinks run and is always now
or in the past, there is no need to hold the infinite value.

Migrate from ipblocks to block/block_target and drop the ipblocks
table. Update tests.
In PostgresUpdater, change some schema update functions to skip field
updates if the table doesn't exist, by analogy with
DatabaseUpdater::modifyField.

Wikidata is at 51.3% of its maximum value (see [1]), so we still have
comfortable time to make this change, but it will inevitably be
necessary and there is no point in postponing this change into the
future. The autoincrement value will not get smaller. ¯\_(ツ)_/¯
Also since rc only stores stuff for 30 days, the table is not that
big.

After exhuastive research, we concluded that iwl_prefix_from_title is
not used and in case it's actually used, other indexes provide enough
cardinality.
This table is about to grow quite large in Commons, let's avoid making
it bigger than it needs to be.

This table has eight indexes plus PK. It has around 1000 rows only. Even
if it needs these indexes (which it doesn't), they are still useless.
Looking at the code, the only potential useful index is the one on
site_global_key, they are showing up in the report of unused indexes in
the db and I checked with Fandom (which might benefit from an index on
this table) and they said they don't use sites table.

Why:
* Part of a temporary user name is generated from an index that
increments, which is stored in the database.
* As specified in T345855, the index will be restarted each year.
* Also specified in T345855, the year will be included in
generated temporary user names.
What:
* Since the year must be included in the name in order to avoid
naming conflicts if the index is restarted each year, both are
implemented together and controlled by a single config.
* Add a new config option that, when true, restarts the name
generation index at the start of each year and add the year into
the user name: $wgAutoCreateTempUser['serialProvider']['useYear']
* Add a uas_year column to the user_autocreate_serial table, which
is unique in combination with uas_shard, so the index can be
stored for each shard/year combination.
* The year is added into the username just after the prefix, as
specified in T345855. This is based on research that having the
year near the start of the name aids understanding that the
names are not IP addresses. The position of the year within the
name is therefore not configurable (though whether to include
it is). See T345855 for the research.

We need to drop these columns and we need to make them take default
values so we can issue write queries without these columns.
Also noting that MySQL prior to 8.0 can't set default values to blob
columns making this way more complicated than it should be but MariaDB
can set them (https://mariadb.com/kb/en/blob/). We also made these
columns nullable to make this work in MySQL.

- schema change to allow tl_namespace and tl_title being empty
This is done by removing them from primary key. They don't need to be
nullable as they have default value.
- Make sure with WRITE_NEW, updater avoids writing to the old columns

Add services and utilities for automatic creation of temporary user
accounts on page save, in order to avoid exposing the user's IP
address.
* Add $wgAutoCreateTempUser, for configuring the system
* Add TempUserConfig service, which interprets the config.
* Add TempUserCreator service, which creates users during page save as
requested by EditPage. With proxy methods to TempUserConfig for
convenience.
* Add table user_autocreate_serial. Table creation is necessary before
the feature is enabled but is not necessary before deployment of this
commit.

be used as a tie-breaker for modtime and also for faster
cas() operations. The flags field makes serialization and

On very heavily edited wikis, it is possible for the value of signed
int to be too small. This increases the max value of rc_id from
2,147,483,647 to 4,294,967,295. It also makes it more consistent with
AUTO_INCREMENT PRIMARY KEY columns on other tables.

This table is massive but thankfully we fixed most of its complexities
in previous patches.
For MySQL/Sqlite:
- Change type of rc_title and rc_source from "varchar binary" to
"varbinary"
- Drop default of rc_timestamp
- Change rc_timestamp from varbinary(14) to binary(14) to standardize
timestamp datatypes
One index doesn't follow the uniform prefix rule but since it's in a
maintenance script, will fix that in a follow up.
