Added the Social Groups plugin. This is still under construction. Made a few improvements to the ForumStore, including bringing it's API closer in line with the other datastores, adding stubs for future subforum functionality, and improving efficiency in a few places. The auth interface now handles all the authentication stuff. Renamed the debug config variable to debug_mode. Added the PluginPerms API. Internal Errors will now dump the stack trace in the console. Added support for installable plugins. Refactored the routing logic so that the router now handles the common PreRoute logic(exc. /static/) Added the CreateTable method to the query generator. It might need some tweaking to better support other database systems. Added the same CreateTable method to the query builder. Began work on PostgreSQL support. Added the string-string hook type Added the pre_render hook type. Added the ParentID and ParentType fields to forums. Added the get_forum_url_prefix function. Added a more generic build_slug function. Added the get_topic_url_prefix function. Added the override_perms and override_forum_perms functions for bulk setting and unsetting permissions. Added more ExtData fields in a few structs and removed them on the Perms struct as the PluginPerms API supersedes them there. Plugins can now see the router instance. The plugin initialisation handlers can now throw errors. Plugins are now initialised after all the forum's subsystems are. Refactored the unit test logic. For instance, we now use the proper .Log method rather than fmt.Println in many cases. Sorry, we'll have to break Github's generated file detection, as the build instructions aren't working, unless I put them at the top, and they're far, far more important than getting Github to recognise the generated code as generated code. Fixed an issue with mysql.go's _init_database() overwriting the dbpassword variable. Not a huge issue, but it is a "gotcha" for those not expecting a ':' at the start. Fixed an issue with forum creation where the forum permissions didn't get cached. Fixed a bug in plugin_bbcode where negative numbers in rand would crash Gosora. Made the outputs of plugin_markdown and plugin_bbcode more compliant with the tests. Revamped the phrase system to make it easier for us to add language pack related features in the future. Added the WidgetMenu widget type. Revamped the theme again. I'm experimenting to see which approach I like most. - Excuse the little W3C rage. Some things about CSS drive me crazy :p Tests: Added 22 bbcode_full_parse tests. Added 19 bbcode_regex_parse tests. Added 27 markdown_parse tests. Added four UserStore tests. More to come when the test database functionality is added. Added 18 name_to_slug tests. Hooks: Added the pre_render hook. Added the pre_render_forum_list hook. Added the pre_render_view_forum hook.

Fixed a bug where it would use the wrong templates for Tempra Simple, Tempra Cursive, and Shadow Likes are now done over AJAX. Posts you have liked are now visually differentiated from those which you have not. Added support for OR to the where parser. || and && now get translated to OR and AND in the where parser. Added support for ( and ) in the where parser. Added an adapter and builder method for getting the database version. Multiple wheres can now be chained with the micro and accumulator builders. Added the In method to the accumulator select builder. Added the GetConn method to the builder. /uploads/ files should now get cached properly. Added more tooltips for topic titles and usernames. Fixed a bug in the runners where old stale templates would be served. Fixed a bug where liking topics didn't work. Began moving the database initialisation logic out of {adapter}.go and into querygen. Tweaked the alert direction to show the newest alerts rather than the oldest. Tweaked the WS JS to have it handle messages more efficiently. Partially fixed an issue where inline edited posts would lack newlines until the page is refreshed. Used arrow functions in a few places in global.js to save a few characters. Schema: Added the liked, oldestItemLikedCreatedAt and lastLiked columns to the users table. Added the createdAt column to the likes table. MySQL Update Queries: ALTER TABLE `users` ADD COLUMN `liked` INT NOT NULL DEFAULT '0' AFTER `topics`; ALTER TABLE `users` ADD COLUMN `oldestItemLikedCreatedAt` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP AFTER `liked`; ALTER TABLE `users` ADD COLUMN `lastLiked` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP AFTER `oldestItemLikedCreatedAt`; ALTER TABLE `likes` ADD COLUMN `createdAt` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP AFTER `sentBy`; delete from `likes`; delete from `activity_stream` where `event` = 'like'; delete from `activity_stream_matches` where `asid` not in(select `asid` from `activity_stream`); update `topics` set `likeCount` = 0; update `replies` set `likeCount` = 0;

UNSTABLE: Began work on the Nox Theme. Removed the Tempra Cursive Theme. You can now do bulk moderation actions with Shadow. Added: Argon2 as a dependency. The EmailStore. The ReportStore. The Copy method to *Setting. The AddColumn method to the query builder and adapters. The textarea setting type. More logging to better debug issues. The GetOffset method to the UserStore. Removed: Sortable from Code Climate's Analysis. MemberCheck and memberCheck as they're obsolete now. The obsolete url_tags setting. The BcryptGeneratePasswordNoSalt function. Some redundant fields from some of the page structs. Revamped: The Control Panel Setting List and Editor. Refactored: The password hashing logic to make it more amenable to multiple hashing algorithms. The email portion of the Account Manager. The Control Panel User List. The report system. simplePanelUserCheck and simpleUserCheck to remove the duplicated logic as the two do the exact same thing. Fixed: Missing slugs in the profile links in the User Manager. A few template initialisers potentially reducing the number of odd template edge cases. Some problems with the footer. Custom selection colour not applying to images on Shadow. The avatars of the bottom row of the topic list on Conflux leaking out. Other: Moved the startTime variable into package common and exported it. Moved the password hashing logic from user.go to auth.go Split common/themes.go into common/theme.go and common/theme_list.go Replaced the SettingLabels phrase category with the more generic SettingPhrases category. Moved a load of routes, including panel ones into the routes and panel packages. Hid the notifications link from the Account Menu. Moved more inline CSS into the CSS files and made things a little more flexible here and there. Continued work on PgSQL, still a ways away. Guests now have a default avatar like everyone else. Tweaked some of the font sizes on Cosora to make the text look a little nicer. Partially implemented the theme dock override logic. Partially implemented a "symlink" like feature for theme directories. ... And a bunch of other things I might have missed. You will need to run this update script / patcher for this commit. Warning: This is an "unstable commit", therefore some things may be a little less stable than I'd like. For instance, the Shadow Theme is a little broken in this commit.

SimpleInsert(name string, table string, columns string, fields string) (string, error)
You can now manage the attachments for an opening post by hitting edit. The update system now uses the database as the source of truth for the last version rather than lastSchema.json Refactored several structs and bits of code, so we can avoid allocations for contexts where we never use a relative time. Clicking on the relative times on the topic list and the forum page should now take you to the post on the last page rather than just the last page. Added the reltime template function. Fixed some obsolete bits of code. Fixed some spelling mistakes. Fixed a bug where MaxBytesReader was capped at the maxFileSize rather than r.ContentLength. All of the client side templates should work again now. Shortened some statement names to save some horizontal space. accUpdateBuilder and SimpleUpdate now use updatePrebuilder behind the scenes to simplify things. Renamed selectItem to builder in AccSelectBuilder. Added a Total() method to accCountBuilder to reduce the amount of boilerplate used for row count queries. The "_builder" strings have been replaced with empty strings to help save memory, to make things slightly faster and to open the door to removing the query name in many contexts down the line. Added the open_edit and close_edit client hooks. Removed many query name checks. Split the attachment logic into separate functions and de-duplicated it between replies and topics. Improved the UI for editing topics in Nox. Used type aliases to reduce the amount of boilerplate in tables.go and patches.go Reduced the amount of boilerplate in the action post logic. Eliminated a map and a slice in the topic page for users who haven't given any likes. E.g. Guests. Fixed some long out-dated parts of the update instructions. Updated the update instructions to remove mention of the obsolete lastSchema.json Fixed a bug in init.js where /api/me was being loaded for guests. Added the MiniTopicGet, GlobalCount and CountInTopic methods to AttachmentStore. Added the MiniAttachment struct. Split the mod floaters out into their own template to reduce duplication. Removed a couple of redundant ParseForms. Added the common.skipUntilIfExistsOrLine function. Added the NotFoundJS and NotFoundJSQ functions. Added the lastReplyID and attachCount columns to the topics table.

Added support for HTTP/2 Push. The themes are still going to be a little broken for a while, but here's the progress I've made. Renamed the topics_trow_assign hook to topics_topic_row_assign. Added more debug code to the generated router. Added a robots.txt file. Gosora now responds to favicon.ico requests with a 404 rather than the topic list. Fixed the tests and some of the benchmarks. Changed the default UserCacheCapacity from 100 to 120. Changed the default TopicCacheCapacity from 100 to 200. Added the last replyer to the topics list and the forum pages. Added the BulkCascadeGetMap method to the UserStore. Refactored the topics list and forum page to load the users with a call to the UserStore rather than via a join. WebSockets now work on SSL. Fixed a race condition when the user permissions are initialised at the start of a request. Fixed a race condition when the user permissions for the OP of a topic are initialised. The rows.Close() calls are deferred once more, so that we can catch problems with recover() Improved support for struct pointers in the template compiler. Added a pin emoji to pinned topics to make them stand-out on the Shadow theme, we have some other ideas in mind for this, but I'd like to get Shadow fully functional for this commit. Fixed a bug an issue with Chrome not detecting XHTML style closes on <form>s. Fixed a visual issue with `color` not being set for textarea elements for the Shadow theme. Fixed a function which wasn't getting renamed for PGSQL. Added seven new UserStore tests.
