The parsing of the timecorrection useroption was split over multiple
classes. Combine into a single class and add some testcases.

Remove WRITE_SYNC flag from ChronologyProtector since the current
plan is to simply use a datacenter-local storage cluster.
Move the touched timestamps into the same stash key that holds the
replication positions. Update the ChronologyProtector::getTouched()
comments.
Also:
* Use $wgMainCacheType as a $wgChronologyProtectorStash fallback
since the main stash will be 'db-replicated' for most sites.
* Remove HashBagOStuff default for position store since that can
result in timeouts waiting on a write position index to appear
since the data does not actually persist accress requests.
* Rename ChronologyProtector::saveSessionReplicationPosition()
since it does not actually save replication positions to storage.
* Make ChronologyProtector::getTouched() check the "enabled" field.
* Allow mocking the current time in ChronologyProtector.
* Mark some internal methods with @internal.
* Migrate various comments from $wgMainStash to BagOStuff.
* Update some other ObjectCache related comments.

The name change happened some time ago, and I think its
about time to start using the name name!
(Done with a find and replace)
My personal motivation for doing this is that I have started
trying out vscode as an IDE for mediawiki development, and
right now it doesn't appear to handle php aliases very well
or at all.

To disable mail in tests, use setTemporaryHook after the
service container setup, instead of the soon-to-be deprecated
Hooks::register().

== Motivation
Mute a log channel, for which the Logger object is injected by
service wiring, for a service that is overridden by default,
such as 'DBLoadBalancerFactory'. For that, calling setLogger()
mid-test would be too late.
== Changes
* Add a test-only method to LegacyLogger that makes it possible
to change its `minimumLevel` attribute, thus making it turn
itself into a NullLogger if raised to infinity. This is the
same principle we use already for disabled log channels when
using MediaWiki normally (see LegacyLogger::__construct).
* Previously, the developer's LocalSettings.php was loaded
which includes the Spi configuration. This meant other Spi's
could be configured which means we might not be dealing with
a LegacyLogger object.
Similar to what we do with ObjectCache and JobQueue already,
make the default Spi in tests the same as the normal MW default.
* Add setNullLogger() which makes use of these two.

This removes Language::$dataCache without deprecation, because 1) I
don't know of a way to properly simulate it in the new paradigm, and 2)
I found no direct access to the member outside of the Language and
LanguageTest classes.
An earlier version of this patch (e4468a1d6b) had to be reverted
because of a massive slowdown on test runs. Based on some local testing,
this should fix the problem. Running all tests in languages is slowed
down by only around 20% instead of a factor of five, and memory usage is
actually reduced greatly (~350 MB -> ~200 MB). The slowdown is still not
great, but I assume it's par for the course for converting things to
services and is acceptable. If not, I can try to optimize further.

This code didn't work because the $GLOBALS array is exposed by reference.
Once this reference was broken by unset(), the rest just manipulated a
local array that happens to be called "GLOBALS". It must not be unset or
re-assigned. It can only be changed in-place.
Before this, the execution of a MediaWikiUnitTestCase test stored a
copy of GLOBALS in unitGlobals, then lost the GLOBALS pointer and
created a new variable called "GLOBALS". As such, the tearDown() function
didn't do what it meant to do, either – which then results in odd
failures like T230023
Rewrite it as follows:
* In setup, store the current GLOBALS keys and values, then reduce
GLOBALS to only the whitelisted keys and values.
* In teardown, restore the original state.
* As optimisation, do this from setUpBeforeClass as well, so that
there are relatively few globals to reset between tests.
(Thanks @Simetrical!)
The following tests were previously passing by accident under
MediaWikiUnitTestCase but actually did depend on global config.
* MainSlotRoleHandlerTest (…, ContentHandler, $wgContentHandlers)

This changeset resumes work on T89432 and related tickets
by porting an initial set of tests to the new unit test suite
separated out in I69b92db3e70093570e05cc0a64c7780a278b321a.
The tests were only ported if they worked immediately without
requiring any changes other than changing the test case class
to MediaWikiUnitTestCase and moving the test to the new suite.
If a test failed for any reason (even trivial misconfiguration),
it was NOT ported.
With this change, the unit tests suite now consits of a total
of 455 tests. As before, you can run these tests via the following
command:
$ composer phpunit:unit

This changeset implements T89432 and related tickets and is based on exploration
done at the Prague Hackathon. The goal is to identify tests in MediaWiki core
that can be run without having to install & configure MediaWiki and its dependencies,
and provide a way to execute these tests via the standard phpunit entry point,
allowing for faster development and integration with existing tooling like IDEs.
The initial set of tests that met these criteria were identified using the work Amir did in
I88822667693d9e00ac3d4639c87bc24e5083e5e8. These tests were then moved into a new subdirectory
under phpunit/ and organized into a separate test suite. The environment for this suite
is set up via a PHPUnit bootstrap file without a custom entry point.
You can execute these tests by running:
$ vendor/bin/phpunit -d memory_limit=512M -c tests/phpunit/unit-tests.xml

Trying to avoid resetting services introduces a lot of complexity and
several bugs. We were doing a reset for 70% of @group Database tests
anyway.
Instead:
* Reset services at the start of MediaWikiTestCase::run().
* Capture the actual original service container instead of making a
special shared service container.
* The test-isolated local service container can now only be initialised
non-statically. Revert the recent conversion of overrideMwServices()
to static.
* Store a reference to the local service container in the test case
object. In MediaWikiTestCase, always use the original or local service
container directly, to avoid confusion about which one is active at
the time.
* Remove a lot of unnecessary teardown
* Always call ServiceContainer::destroy() before forceGlobalInstance()
since the memory is not otherwise freed.

this change should be fine. :-)

While running includes/api tests, profiling reports tests are doing
hundred of inserts followed by hundred of matching deletes. That is due
to the search engine updates.
For almost all tests, there is no need to update the search engine, that
is a waste of I/O and CPU cycles.
Speed up the run by using 'SearchEngineDummy'.
Our search tests still pass since they take care of setting up a search
engine.

Merge the PHPUnit parser test runner with the old parserTests.inc,
taking the good bits of both. Reviewed, pared down and documented the
setup code. parserTests.php is now a frontend to a fully featured
parser test system, with lots of developer options, whereas PHPUnit
provides a simpler interface with increased isolation between test
cases.
Performance of both frontends is much improved, perhaps 2x faster for
parserTests.php and 10x faster for PHPUnit.
General:
* Split out the pre-Setup.php global variable configuration from
phpunit.php into a new class called TestSetup, also called it from
parserTests.php.
* Factored out the setup of TestsAutoLoader into a static method in
Maintenance.
* In Setup.php improved "caches" debug output.
PHPUnit frontend:
* Delete the entire contents of NewParserTest and replace it with a
small wrapper around ParserTestRunner. It doesn't inherit from
MediaWikiTestCase anymore since integrating the setup code was an
unnecessary complication.
* Rename MediaWikiParserTest to ParserTestTopLevelSuite and made it an
instantiable TestSuite class instead of just a static method. Got rid
of the eval(), just construct TestCase objects directly with a
specified name, it works just as well.
* Introduce ParserTestFileSuite for per-file setup.
* Remove parser-related options from phpunit.php, since we don't
support them anymore. Note that --filter now works just as well as
--regex used to.
* Add CoreParserTestSuite, equivalent to ExtensionsParserTestSuite,
for clarity.
* Make it possible to call MediaWikiTestCase::setupTestDB() more than
once, as is implied by the documentation.
parserTests.php frontend:
* Made parserTests.php into a Maintenance subclass, moved CLI-specific
code to it.
* Renamed ParserTest to ParserTestRunner, this is now the generic
backend.
* Add --upload-dir option which sets up an FSFileBackend, similar
to the old default behaviour
Test file reading and interpretation:
* Rename TestFileIterator to TestFileReader, and make it read and buffer
an entire file, instead of iterating.
* The previous code had an associative array representation of test
specifications. Used this form more widely to pass around test data.
* Remove the idea of !!hooks copying hooks from $wgParser, this is
unnecessary now that all extensions use ParserFirstCallInit. Resurrect
an old interpretation of the feature which was accidentally broken: if
a named hook does not exist, skip all tests in the file.
* Got rid of the "subtest" idea for tidy variants, instead use a
human-readable description that appears in the output.
* When all tests in a file are filtered or skipped, don't create the
articles in them. This greatly speeds up execution time when --regex
matches a small number of tests. It may possibly break extensions, but
they would have been randomly broken anyway since there is no
guarantee of test file execution order.
* Remove integrated testing of OutputPage::addCategoryLinks() category
link formatting, life is complicated enough already. It can go in
OutputPageTest if that's a thing we really need.
Result recording and display:
* Make TestRecorder into a generic plugin interface for progress output
etc., which needs to be abstracted for PHPUnit integration.
* Introduce MultiTestRecorder for recorder chaining, instead of using
a long inheritance chain. All test recorders now directly inherit from
TestRecorder.
* Move all console-related code to the new ParserTestPrinter.
* Introduce PhpunitTestRecorder, which is the recorder for the PHPUnit
frontend. Most events are ignored since they are never emitted in the
PHPUnit frontend, which does not call runTests().
* Put more information into ParserTestResult and use it more often.
Setup and teardown:
* Introduce a new API for setup/teardown where setup functions return a
ScopedCallback object which automatically performs the corresponding
teardown when it goes out of scope.
* Rename setUp() to staticSetup(), rewrite. There was a lot of cruft in
here which was simply copied from Setup.php without review, and had
nothing to do with parser tests.
* Rename setupGlobals() to perTestSetup(), mostly rewrite. For
performance, give staticSetup() precedence in cases where they were
both setting up the same thing.
* In support of merged setup code, allow Hooks::clear() to be called
from parserTests.php.
* Remove wgFileExtensions -- it is only used by UploadBase which we
don't call.
* Remove wgUseImageResize -- superseded by MockMediaHandlerFactory which
I imported from NewParserTest.
* Import MockFileBackend from NewParserTest. But instead of
customising the configuration globals, I injected services.
* Remove thumbnail deletion from upload teardown. This makes glob
handling as in the old parserTests.php unnecessary.
* Remove math file from upload teardown, math is actually an extension
now! Also, the relevant parser tests were removed from the Math
extension two years ago in favour of unit tests.
* Make addArticle() private, and introduce addArticles() instead, which
allows setup/teardown to be done once for each batch of articles
instead of every time.
* Remove $wgNamespaceAliases and $wgNamespaceProtection setup. These were
copied in from Setup.php in 2010, and are redundant since we do
actually run Setup.php.
* Use NullLockManager, don't set up a temporary directory just for
this alone.
Fuzz tests:
* Use the new TestSetup class.
* Updated for ParserTestRunner interface change.
* Remove some obsolete references to fuzz tests from the two frontends
where they used to reside.
