Bmo

Stuff that landed in 2016 Here’s a sampling of improvements to BMO that were launched in 2016. Improvements to bug-modal We’ve continued to refine the modal bug view, aka the “experimental UI”. The BMO team fixed 39 bugs relating to the new interface in 2016. We’ve got a couple more blockers before we make the modal view the default, which should happen in the middle of January. We know there are a still a few outstanding bugs and some missing functionality, so we will leave the standard view available for a little while, at least until all the blockers of bug 1273046 are resolved. All future improvements to the bug view will happen only on the modal UI, which is not just more usable but also more hackable. ...

For historical reasons (or “hysterical raisins” as gps says) that elude me, the BMO database has been in (ughhh) Pacific Time since it was first created. This caused some weirdness on every daylight savings time switch (particularly in the fall when 2:00-3:00 am technically occurs twice), but not enough to justify the work in fixing it (it’s been this way for close to two decades, so that means lots of implicit assumptions in the code). ...

It’s been a whole year since my last BMO update, partly because I’ve been busy with MozReview (and blogging a lot about it), and partly because the BMO team got distracted from our goals by a few sudden priority changes, which I’ll get to later in this post. Plans from 2014 Even with some large interruptions, we fully achieved three of our five goals for the year and made good progress on a fourth. ...

Everyone loves statistics! Right? Right? Hello? tap tap feedback screech Well anyway, here are some numbers from BMO in 2014: BMO Usage: 33 243 new users registered 45 628 users logged in 23 063 users performed an action 160 586 new bugs filed 138 127 bugs resolved 100 194 patches attached ...

The second half of 2014 was spent finishing up some performance work and shifting into usability improvements, which will continue into 2015. More performance! By the end of 2014, we’d managed to pick most of the low-to-medium-hanging fruit in the world of Bugzilla server-side performance. The result is approximately doubling the performance of authenticated bug views. Here are graphs from January 2014 and October 2014: ...

BMO currently supports five—count ’em, five—ways to search for bugs. Whenever you have five different ways to perform a similar function, you can be pretty sure the core problem is not well understood. Search has been rated, for good reason, one of the least compelling features of Bugzilla, so the BMO team want to dig in there and make some serious improvements. At our Portland get-together a couple weeks ago, we talked about putting together a vision for BMO. It’s a tough problem, since BMO is used for so many different things. We did, however, manage to get some clarity around search. Gerv, who has been involved in the Bugzilla project for quite some time, neatly summarized the use cases. People search Bugzilla for only two reasons: ...

Here’s your mid-year report from the offices, basements, and caverns of BMO! Performance This year we’re spending a lot of time on performance. As nearly everyone knows, Bugzilla’s an old Perl app from the early days of the Web, written way before all the technologies, processes, and standards of today were even dreamt of. Furthermore, Bugzilla (including BMO) has a very flexible extension framework, which makes broad optimizations difficult, since extensions can modify data at many points during the loading and transforming of data. Finally, Bugzilla has evolved a very fine-grained security system, crucial to an open organization like Mozilla that still has to have a few secrets, at least temporarily (for security and legal reasons, largely). This means lots of security checks when loading or modifying a bug—and, tangentially, it makes the business logic behind the UI pretty complex under the hood. ...

A large number of external applications have grown up around Bugzilla serving a variety of purposes. One thing many of these apps have in common is a need to get updates from Bugzilla. Unfortunately, the only way to get notifications of changes was, until recently, to poll Bugzilla. Everyone knows that polling is bad, particularly because it doesn’t scale well, but until recently there was no alternative. Thus I would like to introduce to the world Bugzfeed, a WebSocket app that allows you to subscribe to one or more bugs and get pushed notifications when they change. It’s rather a small app, based on Tornado, and has a very simple interface, so it should scale quite nicely. It relies on a few moving parts to work, but I’ll start with the basics and explain the whole system later. ...

Or, how to migrate to git using only three programming languages Another aspect of Bugzilla has been dragged, kicking & screaming, into the future! On March 11, 2014, the Bugzilla source moved to git.mozilla.org. We’re still mirroring to bzr.mozilla.org (more on that later), but the repository of record is now git, meaning it is the only place we accept new code. Getting over there was no small feat, so I want to record the adventure in the hopes that it can benefit someone else, and so I can look back some day and wonder why I put myself through these things. ...

2013 was a pretty big year for BMO! I covered a bit in my last post on BMO, but I want to sum up just some of the things that the team accomplished in 2013 as well as to give you a preview of a few things to come. We push updates to BMO generally on a weekly basis. The changelog for each push is posted to glob’s blog and linked to from Twitter (@globau) and from BMO’s discussion forum, mozilla.tools.bmo (available via mailing list, Google Group, and USENET). ...
