Non-breaking change. Remaining uses are public interfaces (a constant, two
globals, a config sub-parameter, SQL queries, storage function names), one i18n
message key, and a whole lot of maintenance scripts with calls to the deprecated
function wfWaitForSlaves().

This can be used to discard all values before a certain point in
time, such as periods of severe network problems or misconfiguration
that resulted in missed purges.

Interpret "1 attempt" as non-blocking and use 3 seconds otherwise
(instead of 6 seconds). This means that the WAN cache merge call
does not block.

The get() $cas_token parameter was changed into $flags, which can act
as a switch to make the return value an associative array of details.
pecl and PHP-based memcached BagOStuff class both pass all tests now.

* Provide a default lock-based BagOStuff::cas implementation
* Make RedisBagOStuff::merge() use mergeViaCas()
* Use the raw unserialized string as the redis CAS token to
avoid any bad interaction with __wakeup() methods changing
field values every time
* Make RedisBagOStuff::incr() return false when there is no
such key, not null
* Rewrite merge() test to make the order of write/cas phase
of the parent and child merge() calls well defined instead
of arbitrary usleep() calls
* Avoid cache key reuse in test runs

This warning is new in PHP 7.1, however the behaviour is not new.
This code was already not behaving as it should have. Concatenation
preceeds addition/multiplication. As such, this was producing
(int)-10 each time instead of (str)"key0" through (str)"key10".

Also removed useless line from testLockTSE(). That would have needed
to be using $this->internalCache and those locks are freed immediately.

Callback code that happens to make use of $oldValue might not be able
to handle missing, new, or changed fields due to key version changes.
Overhaul testGetWithSetCallback_versions() to be cleaner and cover the
case of unversioned => versioned keys.

Use of microtime() is now just for baselines, and it is no longer
assumed to be increasing with each call. Such an assumption is
particuliarly bad on Windows.
I've done 100X run rounds with now failures on Windows.

This simply involves passing it through to the set() call
Also added some related commons to adaptiveTTL() involving
usage of this option.

This stores values for very short times while the main
value is a tombstone in case of particularly high traffic.
Also make mutex keys expire immediately on unlock.

If someone writes an object into a BagOStuff, they typically expect that
later changes to the object will not affect the value stored.
MultiWriteBagOStuff's async write handling was violating this
expectation, which is potentially causing T168040.

The used phpcs has a bug, so the version 0.9.0 could not be enforced at the moment.
Will be fixed in next version, see T167168
Changed:
- Remove duplicate newline at end of file
- Add space between function and ( for closures
- and -> &&, or -> ||

Similar to what WANObjectCache and CachedBagOStuff are already doing.

Backend cache queries are now avoided if they are fresh in memory.
Also factor out some code into private methods for clarity.

The warmup cache was not properly prefixed and was also using the entity
IDs instead of the cache keys. Thus, it effectively just wasted a
getMulti() query and resulted in the usual separate GETs anyway.
Added some unit tests for this.

Replaces \TestingAccessWrapper (defined in core) with
\Wikimedia\TestingAccessWrapper (defined in the composer package
wikimedia/testing-access-wrapper).
See https://gerrit.wikimedia.org/r/#/q/topic:librarize-testing-access-wrapper
for downstream patches.
The core version of the class is kept around for a while to avoid
circular dependency problems.

The default will remain PHPUnit 4.x due to PHP 5.5 support.
But, we should allow developers to run tests with newer PHPUnit
versions which are noticably faster (especially for code coverage
reports).
* <https://github.com/sebastianbergmann/phpunit/wiki/Release-Announcement-for-PHPUnit-5.4.0>
PHPUnit 5 deprecates the getMock() shortcut for getMockBuilder()->getMock().
It instead introduces the shortcut createMock() which has better defaults
than getMockBuilder(). For example, it sets 'disableArgumentCloning' and
other things by default.
Going forward, code should either use getMockBuilder directly and configure
it using the setter methods (instead of the confusing variadic arguments
of getMock) or simply use the new minimalistic createMock method. This patch
backports the createMock method to MediaWikiTestCase so that we can start
using it.

* This fixes keys based on some sort of change log.
Updates are wrapped in a mutex and keep track of the
last known good position.
* Make WANObjectReapUpdate class that cleans up title
related keys using the recentchanges table. This triggers
as a deferred updates on RC view.

This works by setting a callback to return the cache set
options. The callback will watch DB reads and create a
merged result from said usage.
This handles callers that are missing getCacheSetOptions().
Change-Id: Ia264f011e45e8cf105480955dad7e2c4c2357b73
Because the process cache can be lagged by virtue of blind TTL,
the HOLDOFF_TTL might not be enough to account for it, so avoid
using it when already inside a callback.
Also split of the tests from the MediaWiki test class, so this
does not require DB access anymore.
