We shouldn't try to set the attribute of a variable which isn't
actually an object as this will lead to the "Creating default
object from empty value" PHP error and it will trigger a further
fatal down the road. This gets triggered in Wikibase and probably
other extension unit tests.

Use the UploadVerifyFile hook instead of the UploadVerification
one as it provides more data about the upload.
This is the first step towards better upload filtering.

lot of code was using ::merge() to create a new AbuseFilterVariableHolder
this is now simplified using a single addHolders method.
merge() still exists as its usful as a static function.
addHolder() is deprecated.

(bug 28633) With $wgUseAutomaticEditSummaries=true, the edit summary is
different between EditFilterMerged and ArticleSaveComplete. AbuseFilter
was using edit summary changes to attempt to detect whether the two
hooks refer to the same edit. If it really is possible for multiple
edits to be performed in the same request, with arbitrary patterns of
EditFilterMerged and ArticleSaveComplete calls, then some more robust
method would be needed to match the hook calls. But I don't think that
is necessary at present.

AF is setting several lazy load variables for the currently editing user.
To do this it's passing along the user name extracted from a user object
and generating a new user object later from that name which is of course
pointless. With this patch I'll pass user objects directly to prevent that.
On top of that I've deprecated a method in AFComputedVariable::compute which
was redundant as there is a more generic one which can solve that task
just fine.
Furthermore I've changed the logging behaviour from serializing the whole
AbuseFilterVariableHolder object to only store the variables. That has two
major advantages:
* The amount of data that needs to be saved on a filter hit is reduced
to about 1/10 of what the old version needed.
* This is much more forward compatible as the old way of saving this
relied on the class structure to stay the same while this is a simple
array containing the vars.
On top of that we now only log variables already set by the time
a filter is hit. On top of the obvious performance increasement
that makes it easier for the user to spot the relevant data.
Another thing this change alters is the way the AbuseFilter internally
works with AbuseFilterVariableHolder objects. Right now we use one for
testing the filter(s) and later we use another one to compute the same
data again in case a filter was hit (for logging)!
This is not thoroughly tested yet, but way more sane than what we're
currently doing!

During testing the context does not always contain a valid
Title object. In those cases AbuseFilter will fail hard.
This changeset makes the filter survive some of those
failures.

This changes the AbuseFilter to use Status objects for internal
error handling. This allows for more flexibility in passing error
messages back from hooks and avoids double escaping.

This makes AbuseFilter use EditFilterMergedContent if support for
the ContentHandler infrastructure is present. This means living
without some nice bits of context, because EditFilterMergedContent
doesn't provide an EditPage object.
This requires core change I99a19c93 to work correctly.

The hook 'AbuseFilter-interceptVariable' can be used
for intercepting any request to recalculate a variable,
and if a handler is returning false the later code
will be skipped. That makes it possible to avoid using
content if the content model is wrong, as it could be
for a Wikibase entity.
The hook uses the same arguments as the hook
'AbuseFilter-computeVariable', thereby making it simple
to move handlers around.
The arguments to the hook are
@param string $method
@param AbuseFilterVariableHolder $vars
@param array $parameters
@param AFPData|array|int|mixed|null|string &$result
Patchset 2: Fix for arg 1 to the hook, it got $this

This change depends on I92f57fc2c3189c42157478de14a8d48045a253b5.
This change provides a handler for AbortAutoAccount hook and adds new
action to the filter: autocreateaccount. Every time the AbortAutoAccount
is invoked the filter is executed. This may create some issues with
users which are affected by a filter, because it may be triggered on
every page view. The AbuseFilter relies on CentralAuth session
blacklisting - for each session the filter will be triggered only
once and then the autocreationg of account will not be attempted.
I don't know why AbortNewAccount hook takes as $message argument
a text of message, however AbortAutoAccount takes a name of the
message. This makes impossible to produce a user friendly message
why account creation is not allowed.

PHP Fatal error: Call to a member function getRawText() on a non-object in /usr/local/apache/common-local/php-1.20wmf1/extensions/AbuseFilter/AbuseFilter.hooks.php on line 29

This change makes EditFilterMerged handler replace all \r\n with \n.
Parser::preSaveTransform replaces \r\n with \n for all texts, so
there are no \r in the database. The hook EditFilterMerged is run
before the text is processed by Parser::preSaveTransform, so the
diff will be useless if the client sends content with \r\n as line
endings.

Instead pass the Article object from the EditFilterMerged hook to the AFComputedVariable object and see whether the object is present to do a parse operation since other code paths won't pass an Article object
Also simplified the fallback code in AFComputedVariable::compute() to simply continue instead of calling the function again.
with MaxSem about the desired course of action. Perhaps later these
can be merged back, but this seemed to be the quickest way to get
AbuseFilter working with SQLite working for now.
That bug is triggering when a user submit an old revision unchanged.
The previous Article->getContent() would fetch the old revision which is
then compared to the user submitted text. Since they are identical, filtering
is skipped entirely.
Any editor can then reinstate an old "bad" revision.
Fix:
* Get latest stored revision to compare user submitted text against. This is
done by using: Article->getRevision()->getRawText().
* Move caching related calls after that.
Follow up r52740.
Redo r100687 I had reverted.
This bug is triggering when a user submit an old revision again. AbuseFilter
considered it to be a null edit although the old revision is certainly
a different text than the current one in the database.
This patch make sure we skip filtering only if we will be comparing with the
lastest content.
Follow up r52740
* Introduce := operator for setting variables
* Throw an exception when user tries to override built-in variable
* Fix UTF-8 handling in fnmatch() fallback
* Copy three main abuse filters from enwiki to test suite
* Fix update.php integration
This has been done by replacing simple associative arrays with an AbuseFilterVariableHolder, which recognises helper classes called AFComputedVariables.
Computation may occur during the abuse filter analysis, or later when testing and reviewing filters.
* Write array literals with one item per line. This makes diffs which add or remove items far easier to interpret, and makes merging such changes feasible. And it looks nicer too.
* Use line breaks to show the logical structure of your code. This enhances readability. Bring similar elements in a list into alignment, in order to reveal the differences between those elements at a glance.
* Removed a fun game of spot-the-difference in AbuseFilterHistoryPager::getQueryInfo(). If I want fun games I'll play UFO:AI.
* Moved some oddly placed assignments (in expressions) to their own statements: such assignments reduce readbility.
-- Introduce tagging of individual changes (revisions, logs, and on recentchanges). The tags are customisable, and currently settable by the Abuse Filter and by the TorBlock extension. The tags can be styled on the various pages on which they appear.
-- Introduces a schema change, three new tables (valid_tag, change_tag, and tag_summary).
* Allow matching on the changes made in an edit (added/removed lines, etc)
* Improve display of variables in details view - standardise the table size, add white-space: pre, font-family: monospace.
* Improve modifiers: add htmlencode/htmldecode/urlencode/urldecode.
* Add 'abuse filter tools', currently consisting of a testing ground for the modifiers. In future, may include facilities for testing filters against user contributions, recent changes, or other sources.
