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:
hg push -f ssh://hg.mozilla.org/try/
, orhg push -f ssh://<username@host>@hg.mozilla.org/try/
?, orhg push -f ssh://hg.mozilla.org/try/ -e 'ssh -l <username@host>
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.

Server Status
- Try server load can be seen at http://build.mozilla.org/builds/pending/try.html
- Pending builds by revision are at http://build.mozilla.org/builds/pending.html
- In-progress builds by revision are are http://build.mozilla.org/builds/running.html
Other Notes
- Finished builds will live on http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/{your_email_changeset} for 4 days
- They are moved to http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/old/{your_email_changeset} for an additional 14 days before removal
- Try repo is reset occasionally, and you may not be able to use TBPL to see your test results after it has been reset.
- If you have any problems please file a bug
- Windows builds have symbols uploaded to http://build.mozilla.org/tryserver-symbols. Windbg and the Visual Studio debugger may use them to help debug crashing try server builds. Instructions for setting this up can be found here: http://developer.mozilla.org/en/docs/Using_the_Mozilla_symbol_server. Make sure you use the aforementioned URL instead of http://symbols.mozilla.org/firefox.
- Suggestions for the future can be made here or file a blocking bug against bug try_enhancements
Other Mozilla Try Servers
- Thunderbird Try Server for the comm-central repository
