* moved getInfoBox into Xml.php as infoBox static method
* moved config-infobox* css classes from config to mw-infobox* in shared
* left getInfoBox as a wrapper in the installer
* Work around HipHop issue 314 (volatile broken) and issue 308 (no compilation detection) by adding some large and ugly compilation detection code to WebStart.php and doMaintenance.php.
* Provide an MW_COMPILED constant which can be used to detect compiled mode throughout the codebase.
* Introduced wfIsHipHop(), which detects either compiled or interpreted mode. Used this to work around unusual eval() return value in eval.php.
* Work around lack of ini_get() in Maintenance.php, by duplicating wfIsHipHop().
* In Maintenance::shouldExecute(), accept "include" as an inclusion function name, since all kinds of inclusion give this string in HipHop.
* Introduced new class MWInit, which provides some static functions in the pre-autoloader environment.
* Introduced MWInit::compiledPath(), which provides a relative path for invoking a compiled file, and MWInit::interpretedPath(), which provides an absolute path for interpreting a PHP file. Used these new functions in the appropriate places.
* When we are running compiled code, don't include files which would generate duplicate class, function or constant definitions. Documented the new requirements on the contents of Defines.php and UtfNormalDefines.php.
* In HipHop compiled mode, it's not possible to have executable code in the same file as a class definition.
** Moved MimeMagic initialisation to the constructor.
** Moved Namespace.php global variable initialisation to Setup.php.
** Moved MemcachedSessions.php initialisation to the caller in GlobalFunctions.php.
** Moved Sanitizer.php constants and global variables to static class members. Introduced an accessor function for the attribs regex, as a new place to put code formerly at file level.
** Moved Language.php initialisation of $wgLanguageNames to Language::getLanguageNames(). Removed the global variable, marked "private" since forever.
* In two places: don't use error_log() with type=3 to append to a file, HipHop doesn't support it. Use file_put_contents() with FILE_APPEND instead.
* Work around the terrible breakage of class_exists() by using MWInit::classExists() instead in various places. In WebInstaller::getPageByName(), the class_exists() was marked with a fixme comment already, so I replaced it with an autoloader solution.
There were two things breaking this:
* X-Frame-Options forbade our final step of the license selector, or the license selection shower, from being loaded properly. This lead to it looking wrong.
* The installation URL fingerprinting broke on the long query string that's on the final step. As a result, the user's selection got saved into a different session subkey, thinking it belonged to a different installation. It would then not get seen by the surrounding page's installer instance, causing the confusion.
Fix removes the X-Frame-Options for the CC bit, and drops query strings before the rest of URL normalization in the fingerprint check so the CC bits now see the same session key as the rest.
* When an upgrade key is entered, or a supplied upgrade key is edited into LocalSettings.php by the upgrader, fetch database settings from LocalSettings.php and AdminSettings.php for use during the upgrade. This allows the DBConnect page to be skipped, making web upgrade almost as easy to use as CLI upgrade.
* Made LocalSettingsGenerator add $wgUpgradeKey in non-commented form, for easier subsequent upgrades.
* Converted the $wgUpgradeKey check to a normal in-sequence page, called ExistingWiki. This allows the removal of related special cases from WebInstaller. The code for WebInstaller_ExistingWiki is loosely based on WebInstaller_Locked.
* Added Status::replaceMessage(), to support informative DB connection error messages from the ExistingWiki page.
* In WebInstaller::getInfoBox(), call parse() with $lineStart=true, so that line-start syntax like bullet points can work.
* Reduced the length of the generated $wgUpgradeKey from 64 to 16. This is ample for what it does, and makes it fit on the screen and not overlap with the right sidebar when when displayed by WebInstaller_ExistingWiki.
* Added $wgUpgradeKey to DefaultSettings.php.
* Fix MIME type on LocalSettings.php download to not be something that IE considers ambiguous. In Firefox, this makes it say "which is a: PHP file" instead of "plain text document" in the download dialog box.
* Really and truly add in a couple files that were supposed to go in with r77898, and fully revert r77860 (which was a reversion of r75832). (Ran previous commit for r77898 from wrong directory. Oops.)
* Fixed issue with help box text not being parsed.
* Modified help system to remove tooltips and instead open/show hidden boxes.
- I am not happy with this design and future revisions will iterate upon it.
- The biggest problem is everything sitting "on top" of itself. I dislike this a great deal and plan on changing it to be more aesthetic and natural; however, I wanted to get a version of this in that allowed for cut-and-pasting and solved the text parsing issue.
- With javascript disabled, help text is visible by default.
* Remove redundancy in checkboxes
* Added i18n entry for "help", which wasn't there for some reason.
* Removed references to tipsy library in installer html
- Kept tipsy library in core; this is being used elsewhere.
* On top of that, also using javascript to hide the input-field if/when not needed, untill needed (PHP has a backup check to only use this value if the radio-button was on 'other')
* Escaping special html characters in the attributes. The message for .mw-help-field-hint contained the phrase " content pages, in a "'''project namespace'''". " which (raw, unescaped) ends the attribute right after the "a". Fixed now.
* Added associated files for tooltip display
* Added associated css rules for tooltip display
* Updated installer's help system in (most?) places to display help as tooltips instead of show/hide system
* Beginnings of visual changes (e.g., less boxes, more color)
* Modified several of the installer's widget display methods
* Added a couple new i18n values
* Fixed small bug in installer logic:
- Password validation on new users was being executed even if there wasn't a $user object
