Build:TryServer

Try Server As Branch

The try server is an easy way to test a patch on all mozilla-central platforms without actually checking the patch into the core repository. You need a Mozilla hg account (level 1) to use push to try.

This new version of Try Server is called try-as-branch because it now works as a branch in the release automation configs in order to match the mozilla-central configs. With this setup we get many benefits in the try server namely debug builds, packaged unittests, and a way to keep tryserver in sync with mozilla-central as enhancements are made to it.

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.
• 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 (linux example). Then you need to push an extra file to the $topsrcdir either:

• .mozconfig-extra with settings to be applied to all mozconfigs
• .mozconfig-extra-$platform to apply changes only to that platform's mozconfig

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

What Gets Tried

The current Try Server is based on the mozilla-central branch. 1.9.2 based try is coming soon, and is being tracked in bug 563822

A push to try kicks off these builders by default:

Builder	If successful triggers
$platform tryserver build	$platform tryserver opt test everythingelse, $platform tryserver opt test mochitests-{1-5}
$platform tryserver leak test build	$platform tryserver debug test everythingelse, $platform tryserver debug test mochitests-{1-5}
Maemo try hg build
Talos runs for each successful build for a platform

Other Notes

• Finished builds will be deleted after 14 days.
• If you have any problems please send mail to release@mozilla.org
• The default mozconfigs used for tryserver builds are available in Hg: http://hg.mozilla.org/build/buildbot-configs/file/default/mozilla2/$platform/tryserver
• Uploading an alternate mozconfig appends to the default mozconfigs.
• 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.
