Build:TryServer

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

To submit a change to the try server:

• For changes to mozilla-central or close enough (e.g. tracemonkey branch), you can hg push -f ssh://hg.mozilla.org/try/
  or
  hg push -f ssh://<username@host@>@hg.mozilla.org/try/

To see the results:

• You'll get an email from each builder with results.
• Look for your changeset on the Try Tinderbox or Try TBPL.
• Compare Talos perf numbers using Pike's talos-node.
• 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

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/tryserver (linux example)

Disabling specific platforms for try push

You can put exit 1 in any mozconfig-extra-$platform in order to cause it to not compile. This is a temporary workaround while we get the web interface back up and with more granularity for selecting the build/test/perf runs desired for a particular try push.

Pending builds

You can find information about pending builds and server load at http://build.mozilla.org/builds/pending/try.html .

Other Notes

• Finished builds will be deleted after 14 days.
• 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.
