Syntax for Custom Try Requests

The goal of this syntax is to allow user to select particular build/unittest/talos combinations in their hg commit message or in pushed config.info file.

Syntax

try:[dbo] p:[desktop_platforms] m:[mobile_platforms] u:[unittests] t:[talos_suites]
# unittests/talos are OPTIONAL - if not present default is None

This covers:

Build Types both(b) || opt(o) || debug(d)
Platforms none || p:{linux,linux64,osx,osx64,win32,win64}
Mobile none || m:{mobile-maemo5-qt, android, etc}
Unittest Suites all || u:{crashtest,reftest,mochitest{1,2,3,4,5},xpcshell,etc}
Talos Suites all || t:{tp4,tscroll,tspider,etc}

Order

Specify build types (opt/debug/both) first then either all platforms or specify what you want then all unittest suites, no unittest suites, or specify a suite (then run for each platform built) then all talos suites, no talos suites, or specify suite (then run for each platform built)

This allows us to cut off at any point and just to a default 'None' for any info not submitted. If the user submits just a build type, they get a "Does is compile?" try run.

Problem with this syntax

Only does test/talos for each platform build, not per opt/debug builder combination (eg. doing crashtest for opt and not debug) this could potentially be addressed in a future iteration if that level of granularity is needed to help with wait times.

Usage Examples

In an hg commit message

 # both opt/debug builds, all platforms, no unittests/talos
 hg commit -m "bug 432432 testing something try:b" 

 # linux debug build, with all unittests, no talos
 hg commit -m "bug 432432 testing something try:d p:linux u:all"

 # mobile-only builds
 hg commit -m "bug 432432 testing something try:o p:none"

 # all builds, desktop platforms, no mobile, unittests & talos (both options work):
 hg commit -m "bug 432432 testing something try:b m:none ut:all"
 hg commit -m "bug 432432 testing something try:b m:none u:all t:all"

 # opt builds on all platforms with talos tp4 & tscroll (no unittests) 
 hg commit -m "bug 432432 testing something try:o t:tp4,tscroll"

In a try.info file

try.info file pushed to $topsrc_dir would look like:

try:b p:all

Scheduler/Builder Parsing

split on 'try:'
then split on ' ' to grab args

Required arguments

first split: type of build

Now we know opt || debug || both

Optional arguments

If the following exist they will be handled as follows:

second split: platforms (if not present default is all)

Now we can create builders and sendchanges for each combo of opt/debug platform builders

third split: unittests || (unittest && talos) (if not present default is none)

if third split exists and is only u: grab array after for test names to build schedulers
if third split exists and is ut: then they want all of both

fourth split: talos (if not present default is none, without overriding -ut from third split)

if fourth split exists and is t: grab array after for test names to build schedulers
