There’s a big change coming on May 16th, 2018:

We’ve replaced the encryption code for secure bugmail.
All OpenPGP-formatted bugmail will be encrypted using the openpgp.js library.
There are no changes to the S/MIME encryption, and if you’re already using S/MIME my recommendation is to continue using it.

There are upsides (such as a new feature and several bugfixes) and only a single downside to…

video of this meeting

1. Updates from Dylan
   1. CyberShadow is a big help getting Harmony in shape to be run by itself
   2. If you’re making a large change, make lots of small pull requests if possible (they can be on the same bug) as it makes it easier to review. That’s been working very well with CyberShadow’s changes.
   3. Bugzilla (Harmony) now working with Mojolicious which is a big deal (mostly for OAuth2 compatibility)
   4. “Rake me over the coals if there’s no 5.0.{next} release by the next meeting”
2. Updates from Dave
   1. Still waiting on hosting info for our bots and email from Mozilla, hopefully soon
   2. History section on the website has been moved to the About page. It’s been updated with the help of Asa Dotzler correcting some inaccuracies and expanding it based on old Mozilla press releases and commit records. https://www.bugzilla.org/about/
3. Next meeting is on Wednesday, May 2, at 9pm BST (UTC+1), 4pm EDT (UTC-4), 1pm PDT (UTC-7)

Thanks to the near-heroic efforts of CyberShadow the unstable harmony branch is getting quite close to being able to run as an independent Bugzilla install. For a number of reasons, bmo has a separate repo for managing its dependencies. Mostly this is about efficiency — dependencies change less often then the code, and we can have much faster builds and CI. In a step towards independence I have…

captainsafia:

In my last blog post, I dove into some of the code behind the sudo command. I thought this was pretty fun. sudo is one of those commands that I use quite often but haven’t had the chance to look into truly. I started thinking about other commands that I use on a daily basis but had little understanding of the internals of. The first command that came to mind is cd. cd stands for change directory. Simply put, it allows you to set your current working directory to a different directory.

$ pwd
~
$ cd dev
$ pwd
~/dev

So, the first thing I did was figure out what exactly was invoked when I ran cd on the command line. I used the which command which displays the path of the binary associated with a particular command.

$ which cd
/usr/bin/cd
$ cat /usr/bin/cd
#!/bin/sh
# $FreeBSD: src/usr.bin/alias/generic.sh,v 1.2 2005/10/24 22:32:19 cperciva Exp $
# This file is in the public domain.
builtin `echo ${0##*/} | tr \[:upper:] \[:lower:]` ${1+"$@"}

Oh, bother! Reading shell scripts can be such a hassle sometimes. I know the tr command is used to translate characters. In this particular case, the second half of the command, the part after the pipe symbol, basically converts the command cd dev to CD dev. I have no idea why this is. In any case, this modified command is passed to the builtin command which is handled by the shell (Bourne shell) that we are using.

I decided to dive into the code for the Bourne shell to see what I might be able to figure out about these builtins. I came across the definition of the cd builtin here. I’ll admit that it was a hassle to read this file. For one, the source for Bash does not have a mirror on GitHub, so I had to browse through a hosted version with a somewhat cumbersome file browser.

Nonetheless, I read through some of the code that was defined in this file. Some of it was in functions, and other bits were in templates, but after a while, I figured that most of the code was a wrapper around a function called chdir. A lot of the functions defined in the cd.def file linked above actually just invoke chdir and handle errors and parameter cleaning.

I did some Googling on what the chdir function is. It’s a function that is a standard part of Unix. So to figure out more about how chdir worked, I had to dive into the code for the Linux kernel which can be found here.

I started, as I usually do, by searching for the term “chdir” using the GitHub search bar. I find that it is accessible and useful. After scrolling through some of the results, I realized that OMG something I learned at university was going to come handy to me.

The chdir function implements a system call. What’s a system call? A system call is a process by which a user program (like Bash) requests access from the kernel to execute a command. Usually, this is done for commands that require a certain amount of privilege. Changing into a directory is a privileged command from the operating system perspective. You’re essentially giving the user access to a new portion of the file system on the machine so it makes sense that programs would have to pass that request to the kernel for security reasons.

So all in all, here is what happens when you run cd on the command line.

1. The cd builtin is invoked as part of the Bash shell.
2. The Bash shell invokes the chdir function.
3. The chdir function is part of Unix and invokes the chdir system call.
4. The Unix kernel executes the chdir call and does its own low-level thing.

I could dive in a little bit more into how #4 works, but let’s be honest, I’ve already read too much code at this point, and my eyes are starting to hurt.

I hope reading this was illuminating for you!

UPDATE: After reading this blog post, Julia Evans (@bork), provided the following insights on why cd is implemented the way it is through an email.

So!! Why is cd a builtin function in bash and not a program? Some builtins (like time) are bash builtins but they would also work as standalone programs. Is cd one of those?

It turns out that cd HAS to be a shell builtin otherwise it wouldn’t work! Here’s why:

Every process has a set of attributes that the Linux kernel stores. These attributes are things like environment variables, signal handlers, and – the process’s current working directory!!!

Processes aren’t allowed to change each other’s attributes (if I’m a program, I can’t change the working directory or environment variables of another process).

SO!! If you had a /usr/bin/cd program that ran chdir, that would be fine, but when you started it it would change its own working directory and exit which is not very helpful. It wouldn’t change the working directory of you (the parent process)

So bash has to call the chdir syscall itself which is why it’s a builtin.

Thanks, Julia!

An experiment for making big changes with smaller commits on GitHub.

It is safe to say that smaller commits is a perennial topic at Mozilla. On the reviewer side, I definitely prefer smaller commits. I find it’s easier — and faster — to review them. Often not in the neighborhood of microcommits, but at least 300-400 line patches. For the thing I work on we use GitHub, and PRs seem to work best on small things.

I’m still hammering out what features I want to see land in BMO this year but one thing I’ve come to realize is that often the way forward on an old code base is through careful deprecation.

Bugzilla comments are, by default, plain text – so typing <U> will produce less-than, U, greater-than rather than underlined text. However, Bugzilla will automatically make hyperlinks out of certain sorts of text in comments. For example, the text http://www.bugzilla.org will be turned into a link: http://www.bugzilla.org. Other strings which get linkified in the obvious manner are:

• bug 12345
• comment 7
• bug 23456, comment 53
• attachment 4321
• mailto:george@example.com
• george@example.com
• ftp://ftp.mozilla.org

A corollary here is that if you type one or more bug numbers in a comment, you should put the word “bug” before each of them, so they gets autolinkified for the convenience of others.

But also, if you have some text you want linkified in this way, perhaps for use in a blog post, status report, wiki page or other place, you can use the handy linkifier, which will do exactly that for you.

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.

HTML email

There was actually no real work involved here, as HTML email was added to BMO years ago. At that time, since it was a new feature, we didn’t enable it by default… and then 4 years went by. Just a couple weeks ago a new BMO user suggested that we implement HTML emails, having no idea that the option was already there (buried in many other preferences). That was the prompting we needed to finally enable it by default.

Readable bug statuses

Emma Humphries added readable statuses prominently displayed at the top of the status panel (in the modal UI only). They quickly summarize the status of a bug in a visible place, mainly for triaging and tracking purposes.

A couple examples:

This is part of Emma’s on-going efforts to improve contributors' experiences.

Time zones

One big change we made this year was hopefully completely invisible to everyone: BMO’s database moved to UTC. When BMO was originally deployed in 1998, the database, being based in California, was set to Pacific Time. 6 years later someone suggested that UTC would be a better choice. When I took over management of the BMO team about 4.5 years ago, I was pretty horrified that a major application would be running in any time zone other than UTC, not in the least because of the confusion caused by an hour being repeated every year when PDT switched back to PST, since the presence or absence of DST is not noted in the database. However, we were never able to justify the required effort to move over to UTC, that is, until last year, as we were setting up a failover system in AWS. RDS, the natural choice for a MySQL-based application, supported only UTC, thus giving us a hard requirement to migrate. A heroic effort by dkl got us smoothly switched over in May 2016.

Memory-usage & perf improvements

We’ve known for some time that Bugzilla has a persistent memory leak. It was never a huge issue because the webheads would automatically restart Apache processes when their memory usage got too high, but it is understandably something that lurks in the back of the minds of the developers working on Bugzilla. Dylan finally got frustrated enough to fix a big leak, which resulted in the webheads restarting much less frequently, which in turn led to a performance increase. He’s been investigating and fixing other such leaks when he finds the time.

Stuff we’re wrapping up in 2017

Some of the bigger projects bled over into 2017.

Content Security Policy

We’ve been working on implementing CSP in BMO, starting with the new modal bug view. It was pretty hairy due to generated HTML, inline JavaScript, and other old web-dev techniques that make security harder. After some back and forth, we’re just about there; see bug 1286290 for progress.

Note that CSP can break browser extensions. Since the modal UI is relatively new, there are probably not too many extensions designed for it; however, we’ll be spreading CSP over time. And of course, we’ll be removing the old bug view at some point, which will definitely break some things.

Elastic Quicksearch

In the spring, Dylan hacked up a prototype of a quicksearch alternative powered by an Elasticsearch index. It’s lightning fast, so we explored setting it up in production. Of course a prototype is always easier than the real thing, and we had to do some structural work to BMO to make it possible, although that in turn has had side benefits. The indexing code is just about ready to roll out, and while we’re verifying that it works correctly, we’ll be finishing up the search code. You can also follow the main tracker bug for the whole deployment.

New stuff in 2017

We’re expecting to wrap up the above features in Q1, and we’ve already developed a road map for the first half of 2017 with some fun and long-awaited features. Emma will be going over this in another post, wearing her hat as BMO product manager, a job she has recently, and graciously, taken on herself!

January 05, 2017 04:54 PM

One recurring subject on the bugzilla support mailing list is the installation of the Perl modules that Bugzilla requires to function. When you are installing on a Linux distribution, the recommended course of action is to use the packages supplied by the distribution. But, on some distributions, these can be of a version lower than what is required by Bugzilla.

One such distribution is RHEL. Version 7 came out in 2014 and its long support life cycle make it popular for people to use it as a base for their bugzilla instance. Using Bugzilla 4.4 is easy because all Bugzilla's mandatory Perl packages are available by default but Bugzilla 5.0 came out after RHEL7 was released and a number of Perl modules aren't available or are outdated. Users then try to install the missing modules themselves, which is something easy to get wrong. I decided to see if this could be made simpler.

My first step was to see if the modules could be supplied in EPEL, a third-party software repository for RHEL and CentOS but some of the modules concerned are in RHEL which makes them impossible to update via EPEL. Another solution is the use of Fedora's COPR, an easy way for Fedora developers to maintain third party repositories for Fedora and/or RHEL.

It took some amount of tweaking to find the package versions that allow you to run Bugzilla 5.0.x without replacing RHEL7's entire Perl stack but the end result is here. Activating a COPR repo is pretty straightforward:

• dnf install dnf-plugins-core
• dnf copr enable eseyman/bugzilla-5.0

At which point, you can install bugzilla just like any other application:

• dnf install bugzilla

The bugzilla package will be updated everytime a new version of Bugzilla is released and its support will end when the Bugzilla developers end support for the 5.0 branch.

May 19, 2016 07:04 PM

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).

However, we’re planning to move BMO to AWS at some point, and their standard db solution (RDS) only supports UTC. Thus we finally had the excuse to do the work, and, after a bunch of planning, developing, and reviewing, the migration happened yesterday without issues. I am unreasonably excited by this and proud to have witnessed the correction of this egregious violation of standard db principles 18 years after BMO was originally deployed.

Thanks to the BMO team and the DBAs!

May 16, 2016 12:52 AM

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.

Alternative Bug Views

Have you tried out the new modal UI? Although not completely finished (it lacks a few features that the standard UI has), it’s very usable. I don’t remember the last time I had to switch back, and I’ve been using it for at least 6 months. Bonus: gone is the intermediate page when you change a bug’s product, a gripe from time immemorial!

Even though there are still a large number of controls, the new UI is a lot more streamlined. glob gave a brief presentation at a Mozilla Project Meeting in November if you’d like to learn more.

The part we haven’t yet undertaken is building on this new framework to provide alternate views of bug data depending on what the user is trying to accomplish. We want to experiment with stripping down the presented data to only what is needed for a particular task, e.g. developing, triaging, approving, etc. The new UI is a lot more flexible than the old, so in 2016 we’ll build out at least one new task-centric view.

GitHub Authentication

If you haven’t noticed, you can log into BMO via GitHub. If you’ve never used BMO before, you’ll be prompted to set up an account after authenticating. As with Persona, only users with no special privileges (i.e. not admins nor people in security groups) can log in via GitHub.

Auth Delegation

Originally designed to smooth the process of logging into Review Board, auth delegation for API keys is actually a general-use feature that greatly improves the user experience, not to mention security, of third-party apps by allowing them to delegate authentication to BMO. There’s now no reason for apps to directly ask for your BMO credentials!

MozReview Details

There’s now a panel just above the attachments table that shows all the MozReview commits associated with the displayed bug along with a bit of other info:

We’re currently sorting out a single method to display other relevant information, notably, status of reviews, and then we’ll add that to this table.

Improved Searchability

This is the big item we haven’t made much progress on. We’ve got a plan to mirror some data to an Elasticsearch cluster and wire it into Quick Search. We’ve even started on the implementation, but it’s not going to be ready until mid-2016. It will increase search speeds, understandably one of the more common complaints about BMO.

Curve balls

We had two sets of surprises in 2015. One was work that ended up consuming more time than we had expected, and the other was important work that suddenly got a big priority boost.

BMO Backup in AWS

The first is that we moved the BMO failover out of a data center in Phoenix and into the cloud. IT did most of the work, but we had to make a series of changes to BMO to facilitate the move. We also had a lot of testing to do to. The upside is that our new failover system has had more testing than our old one had for quite some time!

Hardened Security

In August we found out that an attacker had compromised a privileged BMO account, using a combination of a weak, reused password and an exploit in another web site. In addition to a huge forensics effort from the great security folks at Mozilla, the BMO team implemented a number of security enhancements to BMO, most notably two-factor authentication. This work naturally took high priority and is the main reason for the slippage of our big 2015 goals. Here’s to a more secure 2016!

Other Stuff

As usual, the BMO team rolled out a pile of smaller fixes, enhancements, improvements, and new features. A few notable examples include

• The guided bug-entry form got a nice refresh. This is the form that users without the editbugs permission, i.e. new users, see when entering bugs. You can always get to it via the “Switch to the Bugzilla helper” link at the buttom of the advanced bug-entry form. Note that if you’re an employee, you’ve been given editbugs by default, so you’ve likely never seen the guided form. Check it out—Bugzilla might be friendlier to new contributors than you expect.

• The platform settings for new bugs now default to all hardware and OSes, with a “Use my platform” button to easily set this to the reporter’s system parameters. This should help clear up some confusion between the reporter’s platform versus the platform the bug applies to.

• The ability to block requests for review, feedback, and needinfo.

• The preferences page is now better organized.

• HTML bugmail has microdata to make GMail display a “View bug” button. Thanks to Ed Morley for the patch!

You can always find the exhaustive list of recent changes to BMO on the wiki or on the mozilla.tools.bmo group/mailing list.

The recent release of Bugzilla 5.0 was the first release sporting the new, improved Bugzilla documentation, which has been moved from DocBook XML to reStructuredText to make it easier to edit and so more likely to be up-to-date :-).

Readers of this blog may be particularly interested in the User Guide. Feedback on the new docs is welcome, particularly suggestions for where it is lacking – please use the bug filing link at the bottom of each docs page.

For the past few months, a new experimental modal bug view has been available on bugzilla.mozilla.org. This hides a lot of complexity both through being read-only initially, and also through having expandable and collapsible sections. It is also quicker and less resource-intensive to load. It requires you to click an “Edit” button, which reveals much more UI, when you want to do more than the common operations – add a comment, CC/NI people, or change the Status or Resolution. It is also more dynamic – for example, there are no more interstital pages when moving bugs between Products, because when you change the Product, the new lists of Components, Milestones etc. load into the widgets automatically.

A picture is worth a thousand words. Here’s the initial view:

And here’s the Edit view:

You can enable it in the Preferences – change “Use experimental user interface” to “On”.

Thanks to glob for doing the hard work on making this happen. This view has not yet made it upstream to Bugzilla itself.

As discussed on the Bugzilla developers mailing list/newsgroup and confirmed by project leads, Bugzilla’s new release policy is to end-of-life the oldest supported major version four months after a new major release. Since this is the first time we’re enacting this policy, we’ve extended the date to be 4 months from today rather than from Bugzilla 5.0’s exact release date (July 7th).

Thus Bugzilla 4.2 will be end-of-lifed on 30 November 2015. This means no fixes of any kind will be issued for Bugzilla 4.2 from that date onwards. As usual, all Bugzilla admins are encouraged to upgrade to the latest version of Bugzilla as soon as possible, especially those running 4.2 or earlier.

To expand a bit further on our new EOL process, after a new major release, we will support three major releases (including the new one) for four months.  After four months, we will drop support for the oldest one.  We will continue to support the remaining two until four months after the next release.

For example, currently we support 4.2, 4.4, and 5.0.  In four months’ time we will drop support for 4.2 and support only 4.4 and 5.0.  When the next major version comes out, perhaps 5.2*, we will support 4.4, 5.0, and 5.2.  Four months later, we will drop support for 4.4 and support only 5.0 and 5.2.

* It may be 6.0 if there are major and/or breaking changes.

Today the Bugzilla Project is extremely proud to announce the release of Bugzilla 5.0!

It has been slightly over two years since we released Bugzilla 4.4 on May 2013. This new major release comes with many new features and improvements to WebServices and performance.

We hope that you enjoy and appreciate the results of the past two years of hard work by our entirely-volunteer community.

• Download 5.0
• Release Notes for 5.0

EOL for 4.0.x

Please note that the release of Bugzilla 5.0 also marks End Of Life for the Bugzilla 4.0 series, meaning that there will be no further updates for the 4.0.x series, even if there are serious security
issues found in that series. We recommend that all installations running the 4.0 series upgrade as soon as possible to 5.0.

Complaining about bugzilla.mozilla.org (BMO) is a Mozilla project activity as old as the hills. Back in 2009, it was realised by the Foundation that to make everyone happy was (and still is) an impossible task, and I was given a mandate to “help people solve their own problems”. So around September 2009, I released the first version of my Bugzilla API proxy software, BzAPI. This software presented a clean, well-documented RESTful interface on the front end, and did all sorts of things on the back end (XML, CSV, RPC, HTML scraping) that developers no longer had to worry about. We made a dev server VM for it so people could try it out – api-dev.bugzilla.mozilla.org.

It was popular. Extremely popular. People started building things, and then more things, all of which depended on this server for Bugzilla data. For various reasons, IT never got around to building a production instance, and so over the last five years, I’ve been maintaining this core piece of Mozilla project infrastructure, which was depended on by TBPL and many, many other tools which interfaced with Bugzilla. At its peak, it serviced 400,000 requests per day.

Over the intervening years, BMO itself acquired a REST API which slowly became more capable, and then a BzAPI-compatible API shim was implemented on top of it by the excellent dkl, so people could change their code to access BMO directly just by updating the endpoint URL. After a few false starts, requests to api-dev.bugzilla.mozilla.org are now served directly by BMO, via that shim code. Earlier today, the api-dev VM was finally powered down.

Here’s to you, api-dev. Good job.

The Bugzilla team recently finished a big project to update, rewrite, improve and centralize Bugzilla’s documentation. You can find it at http://bugzilla.readthedocs.org/. In particular, there’s a User Guide which will be useful to, er, Bugzilla users.

If you have suggestions for further improvements to the documentation, please let the team know.

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:

The server now also minifies and concatenates JavaScript and CSS files. This affects cold loads mostly, since these files are cached, but even on reload it saves a few round trips.

As mentioned above, we’re shifting focus away from performance work and towards usability/work-flow improvements, but there will still be perf benefits, both by reducing and delaying loading of content and by making it easier for users to accomplish common tasks.

New, better documentation

We’ve converted the upstream Bugzilla documentation to reStructuredText, massively updated and reorganized it, and, perhaps of most interest to anyone reading this, completely rewrote the API docs, which were very hard to grok.

For BMO specifically, we’ve fixed up the wiki page. We’ve also started a user guide, but it’s just a skeleton at the moment. There are lots of users out there who know the ins and outs of BMO, so feel free to contribute a section!

GMail support

To support Mozilla’s transition to GMail, we added two features. First, we now limit the number of emails sent to a user per minute and per hour, since GMail will temporarily disable accounts that receive too much mail, and some BMO users receive a lot of bugmail. Second, since GMail’s ability to filter mail by headers is limited compared to other email servers, users can now include the X-Bugzilla-* headers in the body via General Preferences.

Other things

• When entering a new bug, after selecting the product, any relevant custom bug-entry forms are now displayed at the top of the form. We also added a full list of all the custom forms in BMO (linked at the bottom of the bug-entry landing page).

• There’s now a UI for your Review History (as reviewer).

• BMO now uses the Fira Sans typeface to improve consistency with other Mozilla web properties, although we reverted to the old monospace style after a lot of negative feedback about Fira’s monospace. If you don’t like Fira, you can always switch to OpenSans by changing your skin in the General Preferences.

• My Dashboard now has an “Interesting Bugs” query. You can see a full description of the bug criteria in the bug’s user story, but in effect it should be close to what you would receive in bugmail. This is useful on its own if you don’t want to rely on bugmail, but we have plans to make it even more useful by adding weighted scoring to order bugs according to how relevant the changes are to you in particular.

• There’s now an easy way to generate a shortened link for search URLs, which tend to be long.

• And just landed yesterday, which is technically 2015 but the result of work done in 2014, is a new look for the guided bug-entry form, aka the Bugzilla Helper, which new BMO users get by default when filing new bugs. It’s the first step of a series of improvements intended to make it easier for new users to file good bugs.

2015!

As I’ve said a few times now, in 2015 we’re going to do a lot of work on improving general BMO-user productivity: usability, UX, work flows, whatever you want to call it. I’ll write more about this later, but here are a few things we’re looking into:

• Experimenting with alternative bug views. There’s a lot of stuff on the standard bug view. Can we give different windows into the data depending on what the user is trying to accomplish? Can we load this data more intelligently, and organize it more intuitively?

• A proper field for MozReview links that dynamically loads and displays state information on the review request.

• Authentication via GitHub. A lot of Mozilla projects are on GitHub, but many use Bugzilla for issue tracking. To make it easier for contributors coming to us via GitHub, we’ll let them log into Bugzilla using their GitHub account.

• As I wrote about in an earlier post, improved searchability.

As usual, if you have questions or comments, you can leave them here, but an even better place is the mozilla.tools.bmo mailing list, also available as a Google Group and via NNTP.

People often wonder how to make searches in Bugzilla faster on large installations. Two things will give you the most bang for the buck:

• Specify you only want open bugs (if that’s true)
• Specify a product (and, if you know it, a component) to search

Do those two things, and your searches will be much faster.

Coincidentally enough, Bugzilla’s “Simple Search” (BMO version) allows you to specify precisely those two things.

December 06, 2014 10:14 PM

The Bugzilla team is aware that there are currently 5 different methods of searching Bugzilla (as explained in yesterday’s presentation) – Instant Search, Simple Search, Advanced Search, Google Search and QuickSearch. It has been argued that this is too many, and that we should simplify the options available – perhaps building a search which is all three of Instant, Simple and Quick, instead of just one of them. Some Bugzilla developers have sympathy with that view.

I, however, having caught the mood of the times, feel that Mozilla is all about choice, and there is still not enough choice in Bugzilla search. Therefore, I have decided to add a sixth option for those who want it. As of today, December 1st, by installing this GreaseMonkey script, you can now search Bugzilla with Yahoo! Search. (To do this, obviously, you will need a copy of GreaseMonkey.) It looks like this:

In the future, I may create a Bugzilla extension which allows users to fill the fourth tab on the search page with the search engine of their choice, perhaps leveraging the OpenSearch standard. Then, you will be able to search Bugzilla using the search engine which provides the best experience in your locale.

Viva choice!

In 2010, johnath did a very popular video introducing people to Bugzilla, called “Bugzilla for Humans“. While age has been kind to johnath, it has been less kind to his video, which now contains several screenshots and bits of dialogue which are out of date. And, being a video featuring a single presenter, it is somewhat difficult to “patch” it.

Enter Popcorn Maker, the Mozilla Foundation’s multimedia presentation creation tool. I have written a script for a replacement presentation, voiced it up, and used Popcorn Maker to put it together. It’s branded as being in the “Understanding Mozilla” series, as a sequel to “Understanding Mozilla: Communications” which I made last year.

So, I present “Understanding Mozilla: Bugzilla“, an 8.5 minute introduction to Bugzilla as we use it here in the Mozilla project:

Because it’s a Popcorn presentation, it can be remixed. So if the instructions ever change, or Bugzilla looks different, new screenshots can be patched in or erroneous sections removed. It’s not trivial to seamlessly patch my voiceover unless you get me to do it, but it’s still much more possible than patching a video. (In fact, the current version contains a voice patch.) It can also be localized – the script is available, and someone could translate it into another language, voice it up, and then remix the presentation and adjust the transitions accordingly.

Props go to the Popcorn team for making such a great tool, and the Developer Tools team for Responsive Design View and the Screenshot button, which makes it trivial to reel off a series of screenshots of a website in a particular custom size/shape format without any need for editing.

Vanilla Bugzilla lets you decide which bugmail you receive based on what changed about a bug. But there are a couple of extensions which give you even more control, and both are installed on bugzilla.mozilla.org. So the new email filtering pipeline is as follows:

Firstly, ComponentWatching, as the name implies, lets you “watch” particular products or components, so you get put on the list to receive bugmail for all changes to any bugs in those products or components. This is very useful if you have an interest in a particular area of the project. You can also watch particular users – that function is built-in.

Secondly, the normal email filters run, which exclude or include you from emails based on the particular fields which have been changed in the bug update.

Lastly, the BugmailFilter extension allows you to define “include” or “exclude” rules based on any one of:

• the field changed
• the current product
• the current component
• your relationship to the bug
• who made the change (useful to exclude changes made by bots).

Using these three capabilities in tandem, it should be possible to carefully control how much bugmail you receive, even if you are using a system like Gmail which does not have good client-side filtering.

November 25, 2014 05:40 PM

The load time for viewing bugs on bugzilla.mozilla.org has got 2x faster since January. See this tweet for graphical evidence.

October 06, 2014 07:33 PM

We did a Bugzilla security release today, to fix some holes responsibly disclosed to us by Check Point Vulnerability Research, to whom we are very grateful. The most serious of them would allow someone to create and control an account for an arbitrary email address they don’t own. If your Bugzilla gives group permissions based on someone’s email domain, as some do, this could be a privilege escalation.

(Update 2014-10-07 05:42 BST: to be clear, this pattern is most commonly used to add “all people in a particular company” to a group, using an email address regexp like .*@mozilla.com$. It is used this way on bugzilla.mozilla.org to allow Mozilla Corporation employees access to e.g. Human Resources bugs. Membership of the Mozilla security group, which has access to unfixed vulnerabilities, is done on an individual basis and could not be obtained using this bug. The same is true of BMO admin privileges.)

These bugs are actually quite interesting, because they seem to represent a new Perl-specific security problem. (At least, as far as I’m aware it’s new, but perhaps we are about to find that everyone knows about it but us. Update 2014-10-08 09:20 BST: everything old is new again; but the level of response, including changes to CGI.pm, suggest that this had mostly faded from collective memory.) This is how it works. I’m using the most serious bug as my example. The somewhat less serious bugs caused by this pattern were XSS holes. (Check Point are going to be presenting on this vulnerability at the 31st Chaos Communications Congress in December in Hamburg, so check their analysis out too.)

Here’s the vulnerable code:

my $otheruser = Bugzilla::User->create({
    login_name => $login_name, 
    realname   => $cgi->param('realname'), 
    cryptpassword => $password});

This code creates a new Bugzilla user in the database when someone signs up. $cgi is an object representing the HTTP request made to the page.

The issue is a combination of two things. Firstly, the $cgi->param() call is context-sensitive – it can return a scalar or an array, depending on the context in which you call it – i.e. the type of the variable you assign the return value to. The ability for functions to do this is a Perl “do what I mean” feature.

Let’s say you called a page as follows, with 3 instances of the same parameter:

index.cgi?foo=bar&foo=baz&foo=quux

If you call param() in an array context (the @ sigil represents a variable which is an array), you get an array of values:

@values = $cgi->param('foo');
-->
['bar', 'baz', 'quux']

If you call it in a scalar context (the $ sigil represents a variable which is a scalar), you get a single value, probably the first one:

$value = $cgi->param('foo'); 
-->
'bar'

So what context is it being called in, in the code under suspicion? Well, that’s exactly the problem. It turns out that functions called during hash value assignment are evaluated in a list context. However, when the result comes back, that value or those values are assigned to be part of uthe hash as if they were a set of individual, comma-separated scalars. I suspect this behaviour exists because of the close relationship of lists and hashes; it allows you to do stuff like:

my @array = ("foo", 3, "bar", 6);
my %hash = @array;
-->
{ "foo" => 3, "bar" => 6 }

Therefore, when assigning the result of a function call as a hash value, if the return value is a single scalar, all goes as you would expect, but if it’s an array, the second and subsequent values end up being added as key/value pairs in the hash as well. This allows an attacker to override values already in the hash (specified earlier), which may have already been validated, with values controlled by them. In our case, real_name can be any string, so doesn’t need validation, but login_name most definitely does, and it already has been by the time this code is called.

So, in the case of the problematic code above, something like:

index.cgi?realname=JRandomUser&realname=login_name&realname=admin@mozilla.com

would end up overriding the already-validated login_name variable, giving the attacker control of the value used in the call to Bugzilla::User->create(). Oops.

We found 15 instances of this pattern in our code, four of which were exploitable to some degree. If you maintain a Perl web application, you may want to audit it for this pattern. Clearly, CGI.pm param() calls are the first thing to look for, but it’s possible that this pattern could occur with other modules which use the same context-sensitive return feature. The generic fix is to require the function call to be evaluated in scalar context:

my $otheruser = Bugzilla::User->create({
    login_name => $login_name, 
    realname   => scalar $cgi->param('realname'), 
    cryptpassword => $password});

I’d say it might be wise to not ever allow hash values to be assigned directly from functions without a call to scalar.

October 06, 2014 07:13 PM

UPDATE: We have reset all passwords on all Landfill test Bugzilla systems. All users will be required to set a new password the next time they access the test Bugzilla systems.

One of our developers discovered that, starting on about May 4th, 2014, for a period of around 3 months, during the migration of our testing server for test builds of the Bugzilla software, database dump files containing email addresses and encrypted passwords of roughly 97,000 users of the test build were posted on a publicly accessible server.  As soon as we became aware, the database dump files were removed from the server immediately, and we’ve modified the testing process to not require database dumps.

Generally, developers who use our test builds have told us they understand that these builds are insecure and may break, so they do not use passwords they would reuse elsewhere.  However, because it is possible that some users could have reused their passwords on other websites or authentication systems, we’ve sent notices to the users who were affected by this disclosure and recommended that they change any similar passwords they may be using. It’s important to note that, unless users reused the password they used on landfill.bugzilla.org, this does not affect bugzilla.mozilla.org email addresses or passwords.

We are deeply sorry for any inconvenience or concern this incident may cause you.

Thanks,

Mark Côté

Milestone bugzilla.mozilla.org bug 1,000,000 was filed on 2014-04-23 at 01:10 ZST by Archaeopteryx (although rumour has it he used a script, as he also filed the 12 previous bugs in quick succession). The title of the bug was initially “Long word suggestions can move/shift keyboard partially off screen so it overflows” (a Firefox OS Gaia::Keyboard bug, now bug 1000025), but has since been changed to “Celebrate 1000000 bugs, bring your own drinks.”

The winner of the sweepstake to guess the date and time is Gijs Kruitbosch, who guessed 2014-04-25 05:43:21 – which is 2 days, 4 hours, 33 minutes and 5 seconds out. This is a rather wider error, measured in seconds, than the previous sweepstake, but this one had a much longer time horizon – it was instituted 9 months ago. So that’s an error of about 0.95%. The 800,000 bug winner had an error of about 1.55% using the same calculation, so in those terms Gijs’ effort is actually better.

Gijs writes:

I’m Dutch, recently moved to Britain, and I’ll be celebrating my 10th “mozversary” sometime later this year (for those who are counting, bugs had 6 digits and started with “2” when I got going). Back in 2004, I got started by working on ChatZilla, later the Venkman JS debugger and a bit of Firefox, and last year I started working on Firefox as my day job. Outside of Mozilla, I play the piano every now and then, and try to adjust to living in a nation that puts phone booths in its cycle paths.

The two runners-up are Håvard Mork (2d 14h 50m 52s out) and Mark Banner (8d 8h 24m 36s out). Håvard writes:

My name is Håvard Mork. I’m a Java software developer, working with Firefox and web localization to Norwegian. I’ve been involved with localization since 2003. I think localization is rewarding, because it is a process of understanding the mindset of the users, and their perception of IT.

I’m surprised that my estimate came that close. I spent almost an hour trying to figure out how much bug numbers grow, and estimate the exponential components. Unfortunately I lost the equation, so need to start over for the 2,000,000 sweepstakes…

Mark writes:

I’m Mark Banner, also known as Standard8 on irc, I work from home in the UK. I came to Mozilla through volunteering on Thunderbird, and then working at Mozilla Messaging. I still manage Thunderbird releases. Alongside those, I am working on the Loop project (formally Talkilla), which is aiming to provide a real time communications service for Mozilla products, built on top of WebRTC.

Gijs will get a Most Splendid Package, and also a knitted thing from Sheeri as a special bonus prize! The other winners will receive something a little less splendid, but I’m sure it’ll be worth having nevertheless.

A migration of Bugzilla and related code from bzr.mozilla.org to git.mozilla.org will be perfomed on Tuesday, 11 March 2014, starting at 17:00 UTC.  At this time, all Bazaar branches on bzr.mozilla.org will be made read-only (aside from a few admin accounts), and the migration to git repos on git.mozilla.org will commence.  It should take around 1.5 hours to migrate everything, after which point write access will be enabled on the git repos for all users previously authorized on bzr.mozilla.org.  A script will periodically mirror changes from git to bzr for all currently supported Bugzilla branches (4.0, 4.2, and 4.4).  Changes will not be mirrored for any other branches of Bugzilla nor any other related branches (extensions, misc, etc.).

We will start mirroring changes to read-only repos on GitHub at some point (to be determined) after the migration to git.mozilla.org. git.mozilla.org will remain the repository of record, meaning the only place to which changes should be committed by developers.  All mirroring, e.g. to GitHub and bzr.mozilla.org, will be unidirectional.

We’ve already done one test migration; see http://git.mozilla.org.  It was successful aside from some missed file deletions, resulting in extra files on a handful of git repos after the migration.  I manually deleted the superfluous files after migration, and I also fixed the migration script to account for this oddity in Bazaar’s fast-export output, so it won’t happen during the real migration.

I would like to open up testing to all developers, starting with another complete, fresh migration, on Tuesday, 18 February 2014, around 17:00 UTC.  To test the git-to-bzr mirroring script, we’ll create a new branch, “migration-test”, off of Bugzilla trunk and run the mirroring script on it after the migration.  We’ll leave it running until the real migration, and I invite anyone with commit access to bzr.mozilla.org to commit changes to the test-migration branch on git and ensure that they are mirrored properly to bzr.

The full migration and testing plan, along with other details, is at https://wiki.mozilla.org/Bugzilla:Migrating_to_git.

Have you written an app or system of some sort which uses the Bugzilla REST API (BzAPI)? If so, please do as the docs have long recommended and make sure you are a member of the mozilla.tools discussion forum. There are several upcoming announcements in the next few weeks and months which you will need to be aware of, and that is where they are going to be posted.

January 22, 2014 02:24 PM

[Note: The closing date for entries was midday ZST on Thursday 5th September 2013, i.e. a long time ago :-).]

Some of you may have noticed that, after a long history of contests, there was no competition to predict the time of arrival of the 900,000th bug on bugzilla.mozilla.org. This was because we were preparing for the big 1M.

Now we are over 9000,00 (can that really be right?), I can reveal that the prize for the Millionth Bug Sweepstake will be the top-of-the-range Most Splendid Package from the Mozilla Gear Store, which includes a black hoodie, a drawstring tote bag, a Moleskine notebook, and a Rickshaw laptop bag, all Firefox or Mozilla-branded.

The aim of the contest is simple – you need your guess to be the closest to the actual filing date of the one millionth bug in our Bugzilla installation.

To enter, email me a plain text email at gerv@mozilla.org, ideally using this link, filling in the date and time you think the one millionth bug will be filed, along with your Bugzilla ID or email address. As the link suggests, your entry should be on the first line of your email, and formatted as follows:

2010-09-08 06:54:32 bugzilla-id@example.com

All times are in ZST (‘Zilla Standard Time, a.k.a. Pacific Time, as displayed in Bugzilla timestamps unless you’ve changed a pref). If you prefer to be contacted on a different address, add that as well, in brackets on the end of the same line. We have ample graphs and charts (requires editbugs) to help you with your assessment. But if you can’t be bothered to do any research and analysis, just guess optimistically and hope!

This is a Mozilla community event. To keep it that way, entrants must have either a Bugzilla account on bugzilla.mozilla.org created before the end of July 2013, and which has done something useful in the past six months, or a Mozillians account vouched for before the same date. Anyone who meets those criteria can (and is encouraged to) enter, including Mozilla employees. Once the bug is filed, I’ll check those entries who are closest, and keep discarding them until I find one which meets these criteria. Therefore, there’s no point posting this to Slashdot or any other non-Mozilla-focussed news source. But please do post it in Mozilla news sources!

Badly-formatted entries may be discarded. The judge’s decision is final, and any funny business regarding the filing of bugs on or around the one million mark will be frowned upon. The closing date for entries is midday ZST on Thursday 5th September 2013.

I am proud to announce the release of version 1.3 of the Bugzilla REST API. This maintenance release has a bug fix or two, and fully supports the version of Bugzilla 4.2 which has just been deployed on bugzilla.mozilla.org. For smooth interaction with BMO, you should be using this version.

The installation of BzAPI 1.1 on api-dev.bugzilla.mozilla.org will go away in 4 weeks, on 4th April. There is a limit to the number of old versions we can support on the server, particularly as the older ones can put a larger load on Bugzilla and may not work correctly. Please use either the /1.3 or the /latest endpoints. Now that BzAPI has been stable for some time, tools which earlier rejected using the /latest endpoint may want to reconsider.

[Update 2013-01-23 18:35 GMT – turns out there are a couple of Persona features we still need to be absolutely certain that this is a good thing. The change has been reverted until we’ve got those. Sorry for any confusion.]

In April last year, we enabled Persona logins on bugzilla.mozilla.org using a Bugzilla extension I wrote. However, we restricted this login method to low-privilege accounts only while Persona and the extension both matured.

I’m pleased to say that, as of now, unless you are a member of the administrative Bugzilla groups “admin”, “editusers” or “editgroups”, or the “legal” group, then you can now use Persona to log in to bugzilla.mozilla.org :-) In particular, this means all Mozilla employees and security group members can now log in this way.

Make sure you use the correct email address; if you pick a different one to your usual one, Bugzilla will auto-create a Bugzilla account for it.

If for some reason you want b.m.o. not to accept Persona logins for your account, you can do so; file a bug to have your account manually added back to the “no-browser-id” group.

BMO is a core tool in the Mozilla project. There is now a shared, curated space for people’s tips, ideas, best practices, FAQs and so on relating specifically to BMO: https://wiki.mozilla.org/BMO/Support.

This includes Things Every BMO User Really Should Do, and a BMO FAQ (currently in its infancy).

Suggestions for additional content would be very welcome.

“Quicksearch” is a way of searching Bugzilla using simple yet powerful syntax. The search box at the top of every page supports it.

Jesse Ruderman has written a wonderful Quicksearch Reference – a must-read if you search Bugzilla a lot.

December 21, 2012 11:25 AM

To speed up quicksearches, limit the search by product or component. Add “comp: <string>” to your query to limit it to components whose names contain that string. As an abbreviation, you can simply use “:” instead of “comp:”, although that also searches in products whose names which contain the string.

By analogy with the use of “:”, there are abbreviations for some other common fields as well.

(Thanks to Ben Hearsum and Ed Morley)

December 07, 2012 06:20 PM

Another guest post from Stefan Arentz:

“If you do a lot of quick searches to find bugs by summary and you don’t care about also looking into the comments of those bugs, flip the “Include comments when performing quick searches (slower)” to NO in your preferences.

A search for ‘radio antenna’ just went down from 30+ seconds to just a few seconds.”

December 01, 2012 02:12 PM

Guest tip from Stefan Arentz:

“Bugzilla actually does have HTML emails! [As of version 4.2, but it’s been backported to bugzilla.mozilla.org’s 4.0 installation – Ed.] I always though that it did not because I did not look further than the “Email Preferences” tab. But there actually is a “Preferred email format” under the “General Preferences” tab.

This makes Bugzilla emails 100x easier to read on a phone.”

I am proud to announce the release of version 1.2 of the Bugzilla REST API. This maintenance release has a bug fix or two, and some features useful to the admins of Bugzillas which BzAPI is pointed at.

The installation of BzAPI 1.0 on api-dev.bugzilla.mozilla.org will go away in 4 weeks, on 19th December. There is a limit to the number of old versions we can support on the server, particularly as the older ones can put a larger load on Bugzilla. Please use either the /1.2 or the /latest endpoints. Now that BzAPI has been stable for some time, tools which earlier rejected using the /latest endpoint may want to reconsider.

You can now log in to bugzilla.mozilla.org using BrowserID, courtesy of a Bugzilla extension I wrote. Log out and then click the “Login” link in the header and then the orange “Sign in” button to try it.

You can do this – unless, that is, you are a member of certain particularly sensitive groups. While Mozilla has great confidence in the BrowserID technology, it does not have perfect confidence in my coding ;-) Therefore, we are restricting who can log in until we get a little more experience with my extension. Eventually, it’s possible that we might go the other way and require BrowserID for certain sensitive groups, once BrowserID primaries appear with 2-factor authentication. But that’s a little way off yet.

If you visit your permissions page, you can see if you should be able to log in using BrowserID. If you are listed as a member of the “no-browser-id” group, you shouldn’t. Otherwise, you should. The no-browser-id group is currently made up of members of the following groups: admin, bz_sudoers, autoland, generic-assignees, hr, infrasec, legal, and anything with “security” in its name.

Dear Lazyweb,

I know of some software, and it has documentation. I want to be able to maintain this documentation, for the general good of its userbase. At the moment, its documentation is XML files in a VCS, with their own special build procedure with prerequisites. That makes them hard to modify, and as a consequence they are often out of date and certainly not as good as they could be.

Requirement A): I’d like the documentation to be web-editable, because that makes it really easy for anyone to edit quickly, which makes it much more likely the documentation will actually be up-to-date. I want the URL for the “latest version” to always be the same URL.

Requirement B): My software has multiple versions. Once I release a version, I’d like to keep a copy of the documentation in the state that it applies to that version. It may not change much again, but needs to be able to accept bug fixes. However, trunk documentation development must continue. In other words, I need to be able to branch the documentation, check in independently to each branch, and give people URLs to either a branch or the trunk. Each version should have a URL containing the software version number.

Is there any software out there, ideally already in use by the Mozilla project, which can meet both A) and B)? A) is met by all wiki software. B) is met by all version control software. But I haven’t found wiki software with the concept of branches, and I haven’t found a VCS which can display documents prettily and has a web-based interface for editing.

These requirements don’t seem uncommon. Proprietary software solves them. Is there anything open source?

RPMFusion's Bugzilla has gathered a number of bugs over the years and, for lack of maintainance, bugs filed against EOL-ed versions of Fedora have never been closed. The result is a number of open bugs:

I've added a new resolution, EXPIRED, in bugzilla.rpmfusion.org and I'll be using it over the next few weeks to close bugs filed against Fedora 8 through 14. Once a week, I'll be taking one version's bugs and closing them with the EXPIRED resolution and adding a comment on the next version's bugs warning that they will be closed a week later. Once we're done with those, it will probably be time to do the same thing to the Fedora 15 bugs. At that point, we'll probably join the Fedora bug triage cycle, doing this every 6 months.

I recently did up a diagram of how our Bugzilla site was set up, mostly for the benefit of other sysadmins trying to find the various pieces of it.  Several folks expressed interest in sharing it with the community just to show an example of how we were set up.  So I cleaned it up a little, and here it is:

<figcaption class="wp-caption-text">Click the image for a full-size (readable) version</figcaption>

At first glance it looks somewhat excessive just for a Bugzilla, but since the Mozilla Project lives and dies by the content of this site, all work pretty much stops if it doesn’t work, so it’s one of our highest-priority sites to keep operating at all times for developer support.  The actual hardware required to run the site at full capacity for the amount of users we get hitting it is a little less than half of what’s shown in the diagram.

We have the entire site set up in two different datacenters (SJC1 is our San Jose datacenter, PHX1 is our Phoenix datacenter).  Thanks to the load balancers taking care of the cross-datacenter connections for the master databases, it’s actually possible to run it from both sites concurrently to split the load.  But because of the amount of traffic Bugzilla does to the master databases, and the latency in connection setup over that distance, it’s a little bit slow from whichever datacenter isn’t currently hosting the master, so we’ve been trying to keep DNS pointed at just one of them to keep it speedy.

This still works great as a hot failover, though, which got tested in action this last Sunday when we had a system board failure on the master database server in Phoenix.  Failing the entire site over to San Jose took only minutes, and the tech from HP showed up to swap the system board 4 hours later.  The fun part was that I had only finished setting up this hot failover setup about a week prior, so the timing couldn’t have been any better for that system board failure.  If it had happened any sooner we might have been down for a long time waiting for the server to get fixed.

When everything is operational, we’re trying to keep it primarily hosted in Phoenix.  As you can see in the diagram, the database servers in Phoenix are using solid-state disks for the database storage. The speed improvement when running large queries that is gained by using these instead of traditional spinning disks is just amazing.  I haven’t done any actual timing to get hard facts on that, but the difference is large enough that you can easily notice it just from using the site.
