wfSuppressWarnings() and wfRestoreWarnings() were split out into a
separate library. All usages in core were replaced with the new
functions, and the wf* global functions are marked as deprecated.
Additionally, some uses of @ were replaced due to composer's autoloader
being loaded even earlier.
Ie1234f8c12693408de9b94bf6f84480a90bd4f8e adds the library to
mediawiki/vendor.
Bug: T100923
Change-Id: I5c35079a0a656180852be0ae6b1262d40f6534c4
ObjectCache::newFromParams() will handle a 'loggroup' parameter
specially, getting an instance of \Psr\Log\LoggerInterface to
pass to the BagsOStuff.
BagOStuff implementations can use $this->logger which will be
an implementation of \Psr\Log\LoggerInterface. As this is set in
BagOStuff::__construct(), all subclasses must now call the
parent constructor.
The goal of this is to make the logging in BagOStuff non-MediaWiki
specific, in the hopes of separating it out into a separate library
in the future.

Xhprof generates this data now. Custom profiling of various
sub-function units are kept.
Calls to profiler represented about 3% of page execution
time on Special:BlankPage (1.5% in/out); after this change
it's down to about 0.98% of page execution time.

Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.
Also added some missing @param.

* This works with local memcached (e.g. unix:///var/run/memcached/memcached.sock:0 )
and noticeably increases memcached mediawiki performance

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.

* Removed spaces around array index
* Removed double spaces or added spaces to begin or end of function
calls, method signature, conditions or foreachs
* Added braces to one-line ifs
* Changed multi line conditions to one line conditions
* Realigned some arrays

Doxygen expects parameter types to come before the
parameter name in @param tags. Used a quick regex
to switch everything around where possible. This
only fixes cases where a primitve variable (or a
primitive followed by other types) is the variable
type. Other cases will need to be fixed manually.

Added/removed spaces around logical/arithmetic operator
Reduced multiple empty lines to one empty line
Removed wrong tabs before comments at end of line

Memcached response when fetching data typically looks like this:
VALUE <the stored value for whatever key you requested>
END
What the code used to do is read the first line (the VALUE) and re-
assemble the data being fetched there (like unserializing serialized
data). After that, it will read the next line (END).
The value could be a serialized object, which could have a __wakeup.
This __wakeup could have code which in turn executes Memcached-
related stuff. The problem is that, while that object is being
unserialized already, it's wakeup code is attempting to read new
stuff from Memcached, but we have yet to read the END of the data
we're attempting to unserialize (when we'll read a new value from
Memcached, the first thing we'd get is the END we have not yet read..)
The correct way to go about this would be to first read the full
Memcached response, and only unserialize the read data after that.
This is exactly what this patchset does.

Since that revision, messages sent through wfDebugLog() and without
a corresponding entry in $wgDebugLogGroups will be prefixed there
before being sent to wfDebug(), so it's no longer needed to have the
exact same checks for the debug messages in memcached clients.

* merge() will use CAS if supported or use locking otherwise
* The lock()/unlock() methods now have a default implementation
* added unit tests for merge

* When there is a read error, close the socket and mark the server dead,
instead of continuing to send requests through it, causing a protocol
violation.
* Also check for write errors.
* Increase the default stream and connect timeouts from 100ms to 500ms.
* Remove the commented-out _safe_fwrite() code that I wrote in 2005,
that PHP bug is fixed now, so writes can be handled the same way as
reads.
* Fix E_STRICT errors in get_multi() due to a resource being used as an
array index.
* For performance, flush the read buffer less often (only on persistent
connect).
* Move the fread() loop from _load_items() into its own new function.
* Be stricter about stripping expected newlines, don't just run trim() on
everything.
* Make MemCachedClientforWiki into a simple alias since the distinction
with MWMemcached was lost many years ago. We even renamed the class
"MWMemcached".
* Remove vim modeline made incorrect by 19d6293 (Nov 2009).

MemcachedClient output a generic error message: "Error parsing memcached
response\n" whenever it is not able to read from the socket. It is also
lacking the remote peer it is reading from.
This patch add a new message when fgets( <socket> ) return false, which
means we could not read from the file pointer. It also get the stream
remote name for debugging purposes.

MemcachedClient output a generic error message: "Error parsing memcached
response\n" whenever it is not able to read from the socket. It is also
lacking the remote peer it is reading form.
This patch add a new message when fgets( <socket> ) return false and
attempt to get the remote peer address / port to append to the error
message. Might help us find out which memcached server is wild.

When inserting XML elements inline <such as this one>, doxygen chokes
about it not being known. Simply enclosing the tag in double quotes
prevents doxygen from emitting a warning.
Also enclosed a few invalid functions calls such as \. and double quoted
the HTML entities such as &foobar;

* Introduced a common base class for the two memcached clients, called
MemcachedBagOStuff.
* Moved the expiry time normalisation from MemcachedClient.php to
MemcachedBagOStuff since libmemcached needs the same workaround.

When enabling memcached debug logs ($wgMemCachedDebug), they are
unconditionally sent to the main $wgDebugLogFile. This patch make it
possible to sent thoses specific log to an alternate file by setting
$wgDebugLogGroups['memcached']

This reverts the SpecialCachedPage and formatDuration sagas, with some collateral damage here and there. All of these revisions are tagged with 'gerritmigration' and will be resubmitted into Gerrit after the Gerrit switchover.

PHP fatal error in /usr/local/apache/common-local/php-1.18/includes/objectcache/MemcachedPhpBagOStuff.php line 91:
Call to undefined method MemCachedClientforWiki::lock()
* Moved the global functions to GlobalFunctions.php, where they are now just convenience wrappers. Made them return non-references. Updated callers (none found in extensions).
* Added an advanced configuration method, $wgObjectCaches, which allows a lot more detail in the object cache configuration than $wgMainCacheType.
* Made all object cache classes derive from BagOStuff.
* Split the MWMemcached class into a generic client class and a MediaWiki-specific wrapper class. The wrapper class presents a simple BagOStuff interface to calling code, hiding memcached client internals, and will simplify the task of supporting the PECL extension.
* Added some extra constructor parameters to MWMemcached, configurable via $wgObjectCaches.
* Removed the *_multi() methods from BagOStuff, my grepping indicates that they are not used.
* Rewrote FakeMemCachedClient as a BagOStuff subclass, called EmptyBagOStuff.
* Added an optional "server" parameter to SQLBagOStuff. This allows the server holding the objectcache table to be different from the server holding the core DB.
* Added MultiWriteBagOStuff: a cache class which writes to multiple locations, and reads from them in a defined fallback sequence. This can be used to extend the cache space by adding disk-backed storage to existing in-memory caches.
* Made MWMemcached::get() return false on failure instead of null, to match the BagOStuff documentation and the other BagOStuff subclasses. Anything that was relying on it returning null would have already been broken with SqlBagOStuff.
* Fixed a bug in the memcached client causing keys with spaces or line breaks in them to break the memcached protocol, injecting arbitrary commands or parameters. Since the PECL client apparently also has this flaw, I implemented the fix in the wrapper class.
* Renamed BagOStuff::set_debug() to setDebug(), since we aren't emulating the memcached client anymore
* Fixed spelling error in MWMemcached: persistant -> persistent
