.. which sets the --interrupt-budget-for-maglev to a very low value s.t. that tiering to Maglev happens very early. Note this affects both normal tierup and OSR. Also add flag handling to fuzzer.py, both as added globally with probability 0.1, and added to InterruptBudgetFuzzer (which I also updated with other tiering-related flags).

Src-side test specifications
Src-side test specifications enable developers to quickly add tests running on specific bots on V8's continuous infrastructure (CI) or tryserver. Features to be tested must live behind runtime flags, which are mapped to named testing variants specified here. Changes to src-side test specifications go through CQ like any other CL and require tests added for specific trybots to pass.
The test specifications are defined in a V8-side python-literal file
infra/testing/builders.pyl
.
The structure of the file is:
{
<buildername>: {
'tests': [
{
'name': <test-spec name>,
'suffix': <step suffix>,
'variant': <variant name>,
'shards': <number of shards>,
'test_args': <list of flags>,
'swarming_task_attrs': {...},
'swarming_dimensions': {...},
},
...
],
'swarming_task_attrs': {...},
'swarming_dimensions': {...},
},
...
}
The <buildername>
is a string name of the builder to execute the tests.
<test-spec name>
is a label defining a test specification matching the
infra-side.
The optional suffix
will be appended to test-step names for disambiguation.
The optional variant
is a testing variant specified
here.
The optional shards
(default 1) can be provided to increase the swarming
shards for long-running tests.
The optional test_args
is a list of string flags that will be passed to the
V8 test driver.
The optional swarming_task_attrs
is a dict allowing to override the defaults
for priority
, expiration
and hard_timeout
.
The optional swarming_dimensions
is a dict allowing to override the defaults
for cpu
, cores
and os
.
Both swarming_task_attrs
and swarming_dimensions
can be defined per builder
and per test, whereas the latter takes precedence.
Example:
{
'v8_linux64_rel_ng_triggered': {
'tests': [
{
'name': 'v8testing',
'suffix': 'stress',
'variant': 'nooptimization',
'shards': 2,
'test_args': ['--gc-stress'],
'swarming_dimensions': {'os': 'Ubuntu-14.4'},
},
],
'swarming_properties': {'priority': 35},
'swarming_dimensions': {'os': 'Ubuntu'},
},
}
Guidelines
Please keep trybots and continuous bots in sync. E.g. add the same configuration for the release and debug CI bots and the corresponding trybot (where applicable). E.g.
tryserver.v8:
v8_linux64_rel_ng_triggered
client.v8:
V8 Linux64
V8 Linux64 - debug
Please only add tests that are expected to pass, or skip failing tests via status file for the selected testing variants only. If you want to add FYI tests (i.e. not closing the tree and not blocking CQ) you can do so for the following set of bots:
tryserver.v8:
v8_linux64_fyi_rel_ng_triggered
client.v8:
V8 Linux64 - fyi
V8 Linux64 - debug - fyi
