The following previously happened between PreConfigSetup and Setup
and must now happen either before it, after it, or moved inside it.
* WebStart: Detect missing composer.
This must be after Autoloader/Vendor but before the first call to
wfDebugLog (or other loggers) so that we can output a more descriptive
error instead of a generic "Unknown class" fatal error.
Moving it to before Setup is too early, and after is too late.
Move it to within Setup.php and make it work in CLI mode.
* WebStart: Install header callback
Moving it to before Setup is too early, and after is too late.
Move it to within Setup.php (no-op in CLI mode).
* WebStart/Maintenance: Load LocalSetings.
Must be between PreConfigSetup and Setup.
Move to Setup.php to maintain execution order.
Utilise MW_CONFIG_File for custom handling in Maintenance.php.
* WebStart: Initialise output buffering
Utilise (new) MW_SETUP_CALLBACK hook.
* WebStart: Display NoLocalSettings.php
Utilise MW_CONFIG_CALLBACK hook.
* Maintenance: Setting $wgLocalisationCacheConf, calling Maintenance::finalSetup.
Utilise (new) MW_SETUP_CALLBACK hook.

Introduce PreConfigSetup.php, which is common file-scope code run before
LocalSettings.php.
I'm not maintaining autoload.ide.php since it supports closed source
software which I don't have, and it apparently needs significant work to
make it not be weird and hacky.

* Make isTransactableQuery() exclude CREATE/ALTER.
Starting transactions for schema changes like this can cause
errors as it is not supported for MySQL and some Postgres
operations. Note that temporary tables are session-level,
so they are not effected by this change.
* Clean up the transaction logic in determineCoreSchema()
so a transaction is not left dangling.
* Fix broken getSchemaPath() call in PostgresInstaller.
* Avoid warnings in DatabasePostgres::closeConnection() if
mConn is already unset.
* Commit master changes in doMaintenance.php before running
deferred updates, just as MediaWiki.php does.
* Change E_WARNING to E_USER_WARNING to avoid notices in the
default /rdbms error handlers.
* Also avoid trying to rollback in MWExceptionHandler if the
LBFactory service is disabled, which just results in an error.

* Use OutputPage::output() as the method to mask latency, since it
takes a good while to run. By the time it runs, cache replication
should have caught up, so the reap call will likely not block.
* For redirects emitted after changes in POST, instead of masking
with OutputPage, add a parameter to the redirect and block on
the positions appearing. This uses the redirection RTT to mask
the replication latency.

This sets triggers on master position waits typically called
after commitMasterChanges() or in commitAndWaitForReplication().

Maintenance scripts can be invoked regardless of whether an extension is
enabled on a wiki or not. On wiki farms where some wikis may have an
extension or not, this can potentially be rather confusing. Especially
when the script bails out with a fatal class missing error or a database
table missing.
This allows maintenance scripts to specify that they require an
extension by calling:
$this->requireExtension( 'ExtensionName' );
in the script's constructor.

* All callers are either using commit already or would be fine
using it (e.g. Maintenance scripts and JobRunner that have
no real transaction open).

It looks like a recent change converted this try/catch
statement from MWException to Exception, unfortunatly it
is still calling a method that only exists on MWException.
We arn't doing anything with the exception but exiting. Lets
just allow the exception to be uncaught and fail naturally. The
uncaught exception will still output an error and return
a non-0 exit code.

Introduces wfLoadExtension()/wfLoadSkin() which should be used in
LocalSettings.php rather than require-ing a PHP entry point.
Extensions and skins would add "extension.json" or "skin.json" files
in their root, which contains all the information typically
present in PHP entry point files (classes to autoload, special pages,
API modules, etc.) A full schema can be found at
docs/extension.schema.json, and a script to validate these to the
schema is provided. An additional script is provided to convert
typical PHP entry point files into their JSON equivalents.
The basic flow of loading an extension goes like:
* Get the ExtensionRegistry singleton instance
* ExtensionRegistry takes a filename, reads the file or tries
to get the parsed JSON from APC if possible.
* The JSON is run through a Processor instance,
which registers things with the appropriate
global settings.
* The output of the processor is cached in APC if possible.
* The extension/skin is marked as loaded in the
ExtensionRegistry and a callback function is executed
if one was specified.
For ideal performance, a batch loading method is also provided:
* The absolute path name to the JSON file is queued
in the ExtensionRegistry instance.
* When loadFromQueue() is called, it constructs a hash
unique to the members of the current queue, and sees
if the queue has been cached in APC. If not, it processes
each file individually, and combines the result of each
Processor into one giant array, which is cached in APC.
* The giant array then sets various global settings,
defines constants, and calls callbacks.
To invalidate the cached processed info, by default the mtime
of each JSON file is checked. However that can be slow if you
have a large number of extensions, so you can set $wgExtensionInfoMTime
to the mtime of one file, and `touch` it whenever you update
your extensions.

- Put Profiler, ProfileSection and TransactionProfiler in their own
files and rely on Autoloader to use them (maintenance has been
using the autoloader here for some time--we don't profile the
autoloader manually)
- This reduces overhead in WebStart/doMaintenance by only loading
three functions at profiler initialization and defers until the
first profiling call happens
- Inline callback functions in ProfilerSimpleText rather than having
public static functions.
- Small comment and code formatting changes in various touched files.

Shouldn't be needed and aren't for any core operations. If any
extension relies on these $wgTitles being set in maintenance
environments those extensions are broken and should be fixed.

The Line continuation Coding conventions prefers the closing parenthesis
on the same line than the beginning curly braces. This is done for ifs
and functions.
Also move some boolean operator from the end of a line to the beginning
and changed some indentation to make the condition hopefully better
readable.

... as well as the require_once statements in includes/WebStart.php
and maintenance/doMaintenance.php, now that the autoloader lists
MWInit (since r85807 / c68957c5e3).
Also removed code paths in maintenance/userDupes.inc that seem to be
dead (class_exists( 'Revision' ) should always be true) and useless
global/require_once statements in languages/Language.php.

These functions existed to work around a bug (fixed in PHP 5.3) and
a missing feature (added in PHP 5.2) in older versions of PHP;
therefore, they are no longer necessary.

"phpunit/phpunit" already exists inside our composer.json's "require-dev" however this has been
entirely useless as we don't include the autoloader which would load composer's PHPUnit.
This change begins including composer's autoloader when present and also tweaks phpunit.php
to ensure PHPUnit isn't double loaded. As a result besides supporting PHPUnit via composer this
also means that we're ready to make use of any library we add to our composer.json in the future.

Follows-up I1343872de7, Ia533aedf63 and I2df2f80b81.
Also updated usage in text in documentation and the
installer LocalSettingsGenerator.
Most of them were handled by this regex:
- find: (require|include|require_once|include_once)\s*\(\s*(.+?)\s*\)\s*;$
- replace: $1 $2;

hphpc has been superseded by hhvm, so support for hphpc is no longer
needed.
* Continue to use Preprocessor_Hash under HipHop since it is still
faster under hhvm
* Keep $wgCompiledFiles for now, so that wikihiero doesn't give an error
before Ic9d1e795 is merged
* Migrate the run-server script and associated configuration file to
hhvm. Enable EnableStaticContentFromDisk since it doesn't seem
ridiculously inefficient at first glance. Run from $IP rather than
$IP/.. since hhvm is apparently not picky about sourcing files from
outside of the current directory.

Fixed the post-execution calls in doMaintenance.php
to perform proper cleanup after the maintenance
script runs (modeled after MediaWiki::restInPeace).
Added a global call to wfWaitForSlaves() and then
wfDoUpdates() in doMaintenance.php to ensure that
deferred updates are always performed at the end
of maintenance scripts (and that they're performed
after the slaves catch up to avoid lag).
Also added calls to shutdown the DB factory so
that implicit transactions are committed and the
connections are closed.

This move back the maintenance finalSetup code above core Setup.
If we really need to do any setup after core Setup has run, we should use
a new method in the Maintenance class. For example afterCoreSetup()
* Rename Site to WMFSite, less likely to conflict
* Create generic inclusion point for these scripts, so they don't have to duplicate the $IP detection
* Make them all subclass WikimediaMaintenance and move some of the wmf-specific hacks out of core -- almost resolved this crap :D
* Fix rebuildInterwiki to be protocol-relative (like r96139)
* By the way: rebuildInterwiki and dumpInterwiki seem awfully alike...maybe we can merge the two :)
* Added the ability to compile extensions. The build process is bootstrapped by running MediaWiki in interpreted mode. Extension setup file inclusions are slightly modified in a way that makes them register themselves for compilation. Then the same LocalSettings.php uses the compiled extension setup file when the compiled binary runs.
* Tested with Cite and ParserFunctions. The code which lets you have an extensions directory in a place other than $IP/../extensions is untested.
* Simplified WebStart.php slightly by using a custom $_SERVER variable to mark compiled mode. It will break if you don't use the supplied server.conf, but that will break a lot of things so don't do that.
* Fixed the core web entry points to include WebStart.php in compiled mode instead of interpreted.
* Made the build directory configurable. This is mostly so that I can grep the source tree without seeing loads of generated C++.
* In server.conf, added a rewrite rule allowing a /wiki/$1 article path.
* Removed server.conf log file location "/dev/stdout", breaks when you switch user
* Disable static content cache, breaks horribly when you set SourceRoot to a directory containing 7GB of files.
* Rewrote the run-server script in PHP, mostly to support the configurable build directory feature.
* Added an option to the run-server script to allow running in interpreted (hphpi) mode.
