Google Summer of Code Student who went on to become a Mentor/Org Admin

Since 2006, I've probably tried every possible role as a Google Summer of Code participant: accepted student, rejected student, submitter of a rejected organization application, mentor of successful students, mentor of a failing student, co-administrator, and now administrator. Here's my story:

  • In 2006, I had the pleasure of being selected to participate as a student for the Mozilla organization. The work I did on the Page Info dialog eventually shipped as part of Firefox 3.0.
  • In 2007 I applied as a student again, to a different organization, but unfortunately wasn't selected. However, I received an email from someone from the organization who told me the application was good and they would have liked to take me as a student if they had received more slots. He offered to mentor me if I decided to move forward with the project anyway, which I did! I completed the project and in October 2007, Instantbird 0.1 was released. Instantbird is a cross platform, easy to use, instant messaging client based on Mozilla technologies.
  • In 2007, I was selected by Mozilla for an internship in the Firefox team, and spent the end of the year in their headquarters in Mountain View, California. I think this was in large part because people were happy about the work I did in 2006 as a Summer of Code student.
  • In 2008, 2009 and 2010, I focused on Instantbird, which had a growing community of volunteers improving it every day. I sent Summer of Code organization applications on behalf of the Instantbird community, but they weren't accepted. When I asked for feedback, I was told that we should try to work with Mozilla.
  • And this is what we did in 2011! Gerv agreed to let us add Instantbird project ideas to the Mozilla idea list. In 2011 I mentored a student, who completed successfully his work on implementing XMPP in JavaScript for Instantbird. In October I attended the mentor summit in Mountain View.
  • In 2012, I mentored another student, who did some excellent work on improving the user experience for new users during the first run of Instantbird.
  • In 2013, Gerv, who had been handling Summer of Code for Mozilla since the beginning in 2005, asked me if I would be interested in eventually replacing him as an Administrator. After some discussion, I accepted the offer, and we agreed to have a transition period. In 2013, I was backup administrator. I also mentored for the third year in a row. Unfortunately I had to fail my student. This was frustrating, but also a learning experience.
  • In 2014, I submitted the Summer of Code organization application on behalf of Mozilla, it was accepted and we are looking forward to another great summer of code!
  • On a more personal note, after being a Mozilla volunteer for years (since 2004), working on the Thunderbird team (from 2011 to 2012), and then on WebRTC apps (since October 2012), I'm starting in March 2014 as a full time engineer in the Firefox team. Which is the team for which I was a Summer of Code student, 8 years ago.

Mozilla and Google Summer of Code, FOSDEM talk

Last Saturday at FOSDEM, I had the pleasure of giving a talk with Gerv about Mozilla's participation in Google Summer of Code. If you missed us, you can see the slides.

This post is also a good opportunity to remind you to add your ideas to our brainstorm wiki page now if you are interested in mentoring a student this summer.

Project ideas for Summer of Code 2014

Google will be running this year the 10th edition of Summer of Code. Mozilla has had the pleasure of participating every year so far, and we are hoping to participate again this year. In the next 3 weeks, we need to prepare a list of suitable projects to support our application.

Can you think of a 3-month coding project you would love to guide a student through? This is your chance to get a student focusing on it for 3 months! Summer of Code is a great opportunity to introduce new people to your team and have them work on projects you care about but that aren't on the critical path to shipping your next release.

Here are the conditions for the projects:

  • completing the project should take roughly 3 months of effort;
  • any part of the Mozilla project (Firefox, Firefox OS, Thunderbird, Instantbird, SeaMonkey, Bugzilla, L10n, NSS, IT, and many more) can submit ideas, as long as they require coding work;
  • there is a clearly identified mentor who can guide the student through the project.


If you have an idea, please put it on the Brainstorming page, which is our idea development scratchpad. Please read the instructions at the top – following them vastly increases your chances of your idea getting added to the formal Ideas page.

The deadline to submit project ideas and help us be selected by Google is February 14th.

Please feel free to discuss with me any Summer of Code question you may have.

Instantbird bugs should now go to bugzilla.mozilla.org

From 2007 to late 2013, Instantbird bugs were tracked on bugzilla.instantbird.org. This was fine as long as Instantbird was completely separate from all other Mozilla products, but when Instantbird's chat backend was re-used to add instant messaging to Thunderbird, we started having bugs that were relevant for both Instantbird and Thunderbird. Having them in two separate bug trackers was messy and caused lots of duplicates.

We started discussing this at MozCampEU2012 in Warsaw. It quickly became apparent that getting a product created for Instantbird and another one for the chat core wasn't a problem, but that importing our existing bugs would require more work. The plan at this time was to import the existing BIO (bugzilla.instantbird.org) database into BMO (bugzilla.mozilla.org). Unfortunately, while it seems bugzilla already supports importing bugs from plenty of other bug trackers, it doesn't support importing bugs from itself. Some people from the BMO team thought writing such an importer would be a nice and not-very-difficult project, so they agreed to work on it. We filed a bug to figure out the details. And nothing happened for months, because there were (understandably) higher priorities for the BMO team. Ten months later, the BMO team concluded that they were unlikely to ever get time for this project, and suggested we work on another solution instead: using BzAPI to do the import ourselves. This was more work than we could get done immediately, so we kept that in mind for later. Patrick Cloke started experimenting with BzAPI but couldn't get enough of my and others' attention to complete the project.

In December 2013, we decided to move forward with the import, and requested the creation of the products just before the holidays. We drafted a plan in which we broke down the work that needed to happen in several steps that could each be performed by a (relatively) simple and independent script:

  1. first, download all the data from bugzilla.mozilla.org in JSON, create a file for the data of each bug
  2. slice the content of each file from 1. into a stream of events (each event is an action performed by the bugzilla users).
  3. transform the sliced events into events that would apply on BMO (eg. change product names when they don't match exactly on BIO and BMO)
  4. merge the events of all bugs into a single file; without duplicates (eg. when marking a bug as a duplicate of another bug, this creates events on both bugs, but we only need to import one, the other happens automatically).
  5. replay events on BMO: this needs to create a map of new bug and attachment numbers, and replace them automatically in comments.

The plan looked simple on paper (well, on an etherpad). Reality got in the way, with plenty of not-really-expected complications:

  • BzAPI has lots of documented (eg. can't create an attachment at the same time as filing a bug; can't set the component without also setting the product, ...) and undocumented (eg. UTF8 is supported when filing a bug or adding comments, but not when commenting on an attachment) limitations.
  • The format of data downloaded from BzAPI is significantly different from the format of data we need to send it to do changes. This is especially true for attachment flags.
  • Sometimes the values in bug fields don't match what's in the history of events that happened to the bug. This problem occurs when users changed their bugzilla email address, when products got renamed. The worst case we had to deal with was a target milestone that was renamed, then a new target milestone was created with the original name, and some bug's milestone was changed from the renamed milestone to the new milestone with the original name. This caused an interesting complication because we ended up with changes where the mapped value was the same before and after the change.
  • We initially started using the js shell for our scripts, but to do HTTP requests, we needed XPCOM, so we switched to xpcshell instead. Unfortunately, xpcshell's readline() function truncates input data after 255 characters. Later I discovered that xpcshell doesn't handle UTF8 input/output by default, and had to use nsIScriptableUnicodeConverter for that.

Our scripts are all in the bio-merge hg repository. The result of step 4. is a 120MB text file with each line being the JSON representation of an event that needs to be replayed. We tested replaying events on bugzilla-dev.allizom.org first for a single bug, then for a few set of bugs that had dependencies. Finally we replayed our whole set of bugs (2294 bugs, 20984 events), and after fixing the issues that surfaced during that test run, we were ready to do the final import.

The final import took 848 minutes to complete (14 hours). 240 events failed to replay because some components didn't have on BMO the exact names the script expected. I fixed the script and replayed these again.

We finished by adding comments in all existing BIO bugs giving the new URL, and closed BIO (it's now read-only).  As of 2013-12-30, new Instantbird bugs should be filed on bugzilla.mozilla.org, in the Instantbird product for UI bugs, in the Chat Core product for backend issue (this part of the code is shared with Thunderbird), and in the Instantbird Servers product of issues with our servers.

Mozilla Add-Ons Workshop

Samedi, j'ai eu le plaisir de participer au Mozilla Add-Ons Workshop à Paris et de donner une conférence sur la création de composants XPCOM en C++.

Les slides de ma présentation ainsi qu'un fichier zip contenant l'exemple présenté dans les slides sont disponibles.

Les slides sont conçues pour être vues avec l'extension FullerScreen.

Cette journée a été très réussie et, au passage, a permis aux différents membres français de l'équipe Instantbird de se rencontrer.
