This isn't safe given the way python implements default arguments.
Basically python store a reference to the instance it was passed, and
then if that argument is not provided it uses the default. That means
that two calls to the same function get the same instance, if one of
them mutates that instance every subsequent call that gets the default
will receive the mutated instance. The idiom to this in python is to use
None and replace the None,
def in(value: str, container: Optional[List[str]]) -> boolean:
return src in (container or [])
if there is no chance of mutation it's less code to use or and take
advantage of None being falsy. If you may want to mutate the value
passed in you need a ternary (this example is stupid):
def add(value: str, container: Optional[List[str]]) -> None:
container = container if container is not None else []
container.append(value)
I've used or everywhere I'm sure that the value will not be mutated by
the function and erred toward caution by using ternaries for the rest.
* coredata: store cross/native files in the same form they will be used
Currently they're forced to absolute paths when they're stored in the
coredata datastructure, then when they're loaded we de-absolute path
them to check if they're in the system wide directories. This doesn't
work at all, since the ninja backend will generat a dependency on a
file that is in the source directory unless the path was already given
as absolute. This results in builds being retriggereed forever due to
a non-existant file.
The right way to do this is to figure out whether the file is in the
build directory, is absolute, or is in one of the system paths at
creation time, and store that path as absolute. Then the code that
reads the file and the code that generates the dependencies in the
ninja backend just takes the computed list and there is no mismatch
between them.
Fixes#5257
* run_unittests: Add a test for correct native file storage
This tests the bug in #5257
Warn when someone tries to use append() or prepend() on an env var
which already has an operation set on it. People seem to think that
multiple append/prepend operations stack, but they don't.
Closes https://github.com/mesonbuild/meson/issues/5087
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
Since sanity check now includes CFLAGS, the test fails earlier.
But if the compiler is ICC, it will only fail during the build proper as
before, since that's where where the flag making `-std=unknown` an error
not warning is used.
This patch creates an enum for selecting libtype as static, shared,
prefer-static, or prefer-shared. This also renames 'static-shared'
with 'prefer_static' and 'shared-static' with 'prefer_shared'. This is
just a refactor with no behavioral changes or user facing changes.
OpenBSD doesn't have any support for the compiler sanitizers yet.
While this may change in the future, better fix test suite run in "failfast"
mode for now. This can be revisited once (if) we get support in the future.

This provides an initial support for parsing TAP output. It detects failures
and skipped tests without relying on exit code, as well as early termination
of the test due to an error or a crash.
For now, subtests are not recorded in the TestRun object. However, because the
TAP output goes on stdout, it is printed by --print-errorlogs when a test does
not behave as expected. Handling subtests as TestRuns, and serializing them
to JSON, can be added later.
The parser was written specifically for Meson, and comes with its own
test suite.
Fixes#2923.
This makes the testsuite work better with other test runners, like
pytest. This is important because better test runners are very useful to
development (e.g. avoiding running succeeding tests again and again),
even if we want to still support 0 dependency testing of Meson though
keeping the default test runnner working.
