* Refactored to remove massive duplication
* Removed page parameter and associated contextPage member variable, doesn't seem to do anything.
* Put ID lists into a single ids parameter and member variable instead of having one for each type.
* Fixed inappropriate call of Title::newFromUrl(), always wrong
* Don't pretend to use the return value from functions that don't return anything, this reduces readability.
* Use the table names for deleteKey/typeName values, they look more like English
* Use protected not private
* Remove requirement for log type to be specified in the target
* Use POST for RevisionDelete entry forms, to avoid URL size limits and issues with non-PATH_INFO URLs
* Don't purge all pages that use the given file
* LocalFile::purgeCache() already calls purgeHistory,() no need to do it again. But do call purgeDescription().
* Removed token from unhide=1 links, unnecessary
* Tokens are necessary on file streaming links, added them
* Fixed private data leakage due to incorrect use of LocalRepo::newFromArchiveName(). Non-existent placeholder file was returned which meant that $oimage->userCan(File::DELETED_FILE) was always true. Pass the archive name to tryShowFile() instead of the storage key.
* Using ls_field='oi_timestamp' is not correct, oi_timestamp refers to the timestamp of the revision in question, whereas the key that is stored is the timestamp of the previous revision (i.e. the timestamp in oi_archive_name). oi_archive_name would be more correct, although only half the field is used.
Elsewhere:
* Added missing message filehist-missing
* Fixed double asterisk in Status::getWikiText()
* Fixed escaping of the target parameter to Special:RevisionDelete from ImagePage
* Deleted FileStore.php. Deprecated in filerepo refactor except for get()/export() but somehow resurrected by RevisionDelete. Hopefully this will be the end of it. New interfaces will be added for wfStreamFile() in a later commit.
* Added convenience function File::getStorageKey(), factored out of Special:Undelete
* Added convenience function Revision::newFromArchiveRow(), factored out of Special:Undelete and Special:RevisionDelete
* Fixed notice in Special:Upload, uninitialised $pageText
FIXME: current revision can be suppressed on undeletion causing an unauthenticated unsuppress. Comments indicate this is a known issue. I fixed the parser cache pollution in this case but not the rest.
* Do image moving before page moving. That will allow to avoid situations when image page is moved, while image itself isn't.
* Add safeguard code that checks all files before moving them
* More debug logging
