This removes most of the pre-CommentStore text columns, and the
$wgCommentTableSchemaMigrationStage setting that used to determine
whether the columns were used.
rev_comment remains in the code, as on Wikimedia wikis the revision
table is too large to alter at this time. A future change will combine
that with the removal of rev_user_text, rev_content_model, and
rev_content_format (and the addition of rev_comment_id and rev_actor).
CommentStore's constructor continues to take a $stage parameter, and
continues to have the logic for handling it, for the benefit of
extensions that might need their own migration process.

MySQL, SQLite, PostgreSQL and MSSQL done with transitional patches.
One additional duplicate index removed from PostgreSQL schema.
Having a PK is essential to do maintenance, specially on large tasks.
By not having a PK it is impossible to add it in a safe way if not done
directly on the master.
Having a PK means that we can easily change the PK into another one if
needed in the future. The ones we chose might not be the best ones, but
will allow us to get them changed.

PostgreSQL allows setting an "owner" column for a sequence, so if that
column is dropped then the sequence will be dropped too. We should
certainly take advantage of that when creating duplicate tables for unit
testing (particularly when $temporary is false), and we may as well do
it for our permanent tables too.

MediaWiki doesn't support PostgreSQL < 9.2, so drop the support for
older versions.
At the same time, since we're messing with the DatabasePostgres::insert()
code anyway, let's start using ON CONFLICT DO NOTHING for PG >= 9.5.
And since we're doing that, let's do the same for
DatabasePostgres::nativeInsertSelect().

Revisions deleted before MediaWiki 1.5 do not have a value in this

provide a maintenance script to clean this up.
Then, for good measure, change the schema to make the field
non-nullable.

The site stats table holds a bunch of metric fields, two of which are of
data type "bigint unsigned", 3 are "bigint" (signed) and one is int
(signed). Also the default values differ widely: It is 0 on the
"unsigned" fields and the "int" field, but -1 on the three others. This
patch makes all of this more consistent:
Set all fields (except the ss_row_id, which isn't changed) data type to
"bigint unsigned". Also set NULL as the default value for all those
fields. Obviously -1 isn't a possible default value any more. Also, 0
can easily be mistaken for a real value (e.g. ss_active_users=0 -->
"there is nobody active on this wiki"). NULL, by it's definition, is the
value of choice for a value to insert into fields of which we don't know
a correct value.
The respective patch files were tested locally against MySql, Sqlite,
Postgres and SQL Server 2016. Neither oracle nor the upgrade with
update.php was tested.

This begins the process of merging image_comment_temp into the image
table by adding the needed column. Iab5f5215 will adjust the code
to use it and to add the necessary migration script.
Note this patch puts the new schema change in the 1.30 section rather
than the 1.31 section. This allows Iab5f5215 to have migrateComments.php
migrate the comments directly to the new field instead of having to
populate and then depopulate the temporary table.

Storing the user name or IP in every row in large tables like revision
and logging takes up space and makes operations on these tables slower.
This patch begins the process of moving those into one "actor" table
which other tables can reference with a single integer field.
A subsequent patch will remove the old columns.

* Fix schema for image_comment_temp.
* Provide values in CommentStoreTest::provideInsertRoundTrip() for
columns where the PG schema doesn't have a default value but the MySQL
schema does.
* Call nextSequenceValue() from CommentStoreTest::testInsertRoundTrip().
* Correctly handle $options being the string 'FOR UPDATE' in
DatabasePostgres::selectSQLText()
* Correctly handle the initial table in DatabasePostgres::selectSQLText() FOR
UPDATE mangling.
* Correctly handle aliases in DatabasePostgres::selectSQLText() FOR
UPDATE mangling.
Tests in PG are still going to be broken thanks to the fact that
nextSequenceValue() and insertId() can't be separated by another
nextSequenceValue()/insertId() pair. That should be taken care of by
T164898/T164900.

This reverts commit b67f40e5b0.
There was an issue that the web installer, when inserting initial
values into the db table site_stats, would not insert any value for
ss_active_users. That lead to some places, most notably
Special:CreateAccount, to show off -1 recent contributors.
The commit to revert solved this by setting a default value of 1 for
the ss_active_users field in the database schema. However, while the
default schema has been changed, there hasn't been any schema update
procedure implemented. Also, the default of 1 is inconsistent with
other defaults in that table.
Revert that schema change completely. Instead, make the web installer
insert 0 to the field ss_active_users (just like it does with all other
fields in that table).

This patch adds an ug_expiry column to the user_groups table, a timestamp
giving a date when the user group expires. A new UserGroupMembership class,
based on the Block class, manages entries in this table.
When the expiry date passes, the row in user_groups is ignored, and will
eventually be purged from the DB when UserGroupMembership::insert is next
called. Old, expired user group memberships are not kept; instead, the log
entries are available to find the history of these memberships, similar
to the way it has always worked for blocks and protections.
Anyone getting user group info through the User object will get correct
information. However, code that reads the user_groups table directly will
now need to skip over rows with ug_expiry < wfTimestampNow(). See
UsersPager for an example of how to do this.
NULL is used to represent infinite (no) expiry, rather than a string
'infinity' or similar (except in the API). This allows existing user group
assignments and log entries, which are all infinite in duration, to be
treated the same as new, infinite-length memberships, without special
casing everything.
The whole thing is behind the temporary feature flag
$wgDisableUserGroupExpiry, in accordance with the WMF schema change policy.
The opportunity has been taken to refactor some static user-group-related
functions out of User into UserGroupMembership, and also to add a primary
key (ug_user, ug_group) to the user_groups table.
There are a few breaking changes:
- UserRightsProxy-like objects are now required to have a
getGroupMemberships() function.
- $user->mGroups (on a User object) is no longer present.
- Some protected functions in UsersPager are altered or removed.
- The UsersPagerDoBatchLookups hook (unused in any Wikimedia Git-hosted
extension) has a change of parameter.

Bot passwords are something like OAuth-lite, or Google's application
passwords: the bot can use API action=login to log in with the special
username and password, and will then be allowed to use the API with a
restricted set of rights.
This is intended to provide an easy migration path for legacy bots and
for bots on wikis without OAuth, since AuthManager is going to greatly
complicate non-interactive authentication. If OAuth is available, an
owner-only consumer would be a better choice.

Change I1c7f3a84f10df05d6b37dccbad4c8232edf51580 causes
an existing foreign key assumption (under PostgreSQL) to be
violated upon deleting a page. This foreign key assumption does not
explicitly exist in MySQL, and is not implied via documentation. So
it was probably never needed in the first place.
Don't create the foreign key constraint in PostgreSQL, and drop it
if it already exists when running update.php.
The constraint was previously created with an implicit name, so
drop the constraint involving the specified column name (rc_cur_id),
rather than hard-coding the name of the constraint itself.
This bug probably exists under Oracle and MSSQL as well, but no attempt
was made to address it there.
