Try Server

The try server is an easy way to test a patch without actually checking the patch into the core repository. Your code will go through the same tests as a mozilla-central push, and you'll be able to download builds if you wish.

To use try server, you need a Mozilla hg account (level 1 is sufficient).

How to push to try

Running a subset of builds/test/talos available to Try

You must use Build:TryChooser to choose which builds, tests, and talos you would like run on your push to try. Make sure you place the try chooser text in your topmost commit. The TryChooser web page can help you build a commit message for custom requests, so can the mercurial extension

% hg qref --message "try: -b o -e -p all -u all -t none"
% hg push -f try

Pushing to try

To submit your changes to the try server (assuming they're modifications to mozilla-central or a similar branch, e.g. tracemonkey), you have a few options:

Creating an alias

To save yourself some typing, you can add an alias to your hgrc:

[paths]
try = ssh://hg.mozilla.org/try

and then push with

hg push -f try

~/.ssh/config

ssh host settings to make life easier

Host hg.mozilla.org
  User <commit_user_email_address>
  # IdentityFile ~/.ssh/alternate_public_identity_key_file

Viewing the results

You can see the results of your tryserver build in a number of ways:

  • You'll get an email on a successful push with a link to tbpl for your revision as well as emails on any non-successful build/test/talos results (this setting can be adjusted using Build:TryChooser args for email notification)
  • You can have the results of your try run posted to bug(s) automatically at the completion of the run using the --post-to-bugzilla flag in your try syntax (see: Build:TryChooser for examples)
  • Look for your changeset on the Try Tinderbox or Try TBPL (alternate TBPL alternate TBPL). You can add &pusher=YOUR.EMAIL to only see your pushes.
  • Compare Talos perf numbers using Pike's talos-node or mconnor's compare-talos.
  • Download your completed builds from firefox/tryserver-builds on ftp.m.o.

If you're using Mercurial queues, the push -f command pushes any patches that are currently applied, and the Try server will build the result. (This is an awesome feature, not a bug!)

You don’t need to clone or pull from the try repo, and you probably don’t want to. You’d get every half-baked changeset anybody ever tested.

See Jorendorff's blog for more details.

Using a custom mozconfig

If you want to use setting other than those in the default mozconfigs, you can push an extra file to the $topsrcdir:

  • mozconfig-extra with settings to be applied to all mozconfigs
  • mozconfig-extra-$platform to apply changes only to that platform's mozconfig, where $platform is one of linux, linux64, win32, macosx, macosx64, linux-android, maemo5-gtk, maemo5-qt

The options you enable/disable in your custom mozconfig are appended to the existing config.

The default mozconfigs used for tryserver builds are available in Hg: http://hg.mozilla.org/build/buildbot-configs/file/default/mozilla2/$platform/try (linux example)

Using older GCC

Linux and Linux64 build bots are using GCC 4.5 for Try builds. But some branches will fail to build or run tests with this version of GCC because of the libstdc++ dependency it adds. Such branches are those where bug 643690 hasn't landed. If you want to push such a branch to Try, you need to add the following to mozconfig-extra-linux and/or mozconfig-extra-linux64 in the top directory:

CC=/tools/gcc-4.3.3/installed/bin/gcc
CXX=/tools/gcc-4.3.3/installed/bin/g++

How to get non-PGO coverage

On branches where bug 643704 has landed, adding the following in a mozconfig-extra or mozconfig-extra-$platform file will suffice:

mk_add_options MOZ_PGO=

On other branches, fool the system!

Include this in your patch.
