As you may know i was participating in this year Gerrit User Summit, 21-26 March, followed by Developer Hackathon in Mountain View, CA.
I had three presentations: Gerrit@LibreOffice with detailed explanation of Gerrit Buildbot plugin and two feature requests:
Among other presentations Edwin summarized new features in upcoming Gerrit 2.9 release, that was later converted to regular documentation page in Gerrit. Shawn presented plans for future Gerrit/Git development:
- Moving from database to Git to store meta data
- Provide alternative Git storage backend(s) to file system backend.
- Improving Git submodule feature set
During the Hackathon i continued the work on inline edit feature: to allow to change code during review directly in browser. It should also have support to create a new empty isolated change and a follow-up change from a given change directly in browser and allow to populate it with code changes.
On Sunday we had mountain bike tour in Santa Cruz national park. Thanks Edwin for these great pictures:
Big thank to The Document Foundation for funding my participation.
Some history first
First time i compiled LibreOffice (LO) in march 2012, it failed to compile in the seamonkey (moz) module (i didn’t enable it explicitly). I had many questions about moz integration in LO:
- what has an office suite to do with a browser?
- why it is enabled per default, if it’s something optional?
- why it was failing to compile on my recent Ubuntu box?
Six months later i knew the answers to all these questions 😉
- it is needed for Thunderbird address book integration and some other extensions.
- it is (well was) not really optional: mail merge is an important feature, because sooner or later you want to send mails from your office suite to the recipients from your address book. To import the Mozilla Address Book (MAB) data, which is stored in mork file format, LO need some means to read and interpret that format. Because of lack of alternative implementations Mozilla itself was used for that purpose.
- well here things started to become complicated. It was subtle linking issue: compiler tool chain configuration was changed on Debian/Ubuntu: “as-needed” became the default, breaking many tools and libraries, among other the moz module in LO. But why two distros had a compilation problem in the moz module and nobody noticed? Debian/Ubuntu maintainers disabled this “a strangely hacked up Mozilla binary” inside of LO.

As you may know, LibreOffice undergoes currently migration to code review system gerrit. In his post to dev ML Why Gerrit and other consideration Norbert Thiebaud explained the objectives which the initiators of that move are trying to achieve. As though by chance, the first reason behind that move was cit.
a/ Allow dev to pre-build commit on a variety of platform _before_
pushing them to master. iow check and push rather than the current
push and fix. [...]
To see how gerrit fits in current LibreOffice CI picture or what should be done for it let us first take a look at the situation prior to gerrit migration. At the moment there are 23 Tinderboxes (TB), that independently running on donated machines and asynchronously verify different git branches. They upload the build results to the master TB per mail. Master TB extracts the log from the mail and puts it to the web site for that specific branch, i.e. for master you can find it here. Continue reading How Gerrit fits in LibreOffice CI Infrastructure
