The Thunderbird try server works in exactly the same way to the Firefox try server with a few minor differences. The automation is based on the same hardware and tools, so there should be few differences.
To use the try server, you'll need Level 1 Commit Access. You can learn more about Mozilla's commit access policies and start the process of signing up for an account here: Becoming a Mozilla Contributor
Try server has a separate repository based upon comm-central. You'll need to add the address to your Mercurial configuration file at
[paths]default = https://hg.mozilla.org/comm-centraltry = ssh://hg.mozilla.org/try-comm-central
You can of course access the repository via HTTP, but not push to it, hence the ssh:// address.
Having gained level 1 access and configured Mercurial, you can push to Try. In general, it's just a matter of applying your patch(es) and running
hg push try.
You can (and should) control what testing jobs you want to run on your push. This is usually done by using special code (Try syntax) in the commit message of the tip-most revision being pushed, for example
try: -b o -p linux64 -u all creates only an "opt" build on 64-bit Linux, and runs all of the tests on that build.
This is the Try syntax try-comm-central understands:
-b Build type. Use
o for an opt build (most common),
d for a debug build, or
do for both.
-p Platform. There are five platforms. Each also has a
-shippable variant, which is a complication you probably don't need to think about.
linux 32-bit Linux
linux64 64-bit Linux
macosx64 Mac OS (if you don't need a debug build, specify
win32 32-bit Windows
win64 64-bit Windows
all for all platforms
-u Unit test suites.
--artifact Artifact builds. See the Artifact Builds page for more information.
If you have changes that affect mozilla-central, you may wish to do a Try run to check Thunderbird isn't broken. Here's how:
In your mozilla-central directory, apply your patch. Then run
./mach try empty to push to the mozilla-central Try repository. You'll need to know the revision number of your push, which will be in the message printed to the console.
Move to your comm-central directory.
Modify the file
.gecko_rev.yml – change
GECKO_HEAD_REF to point to the revision you previously pushed to M-C's try with
mach try empty.
Now push to try-comm-central as per usual.
You can change
.gecko_rev.yml to point to any revision on the mozilla-* trees to test your comm-central patch against them.
