This default behavior can have surprising and time-consuming outcomes.
I was wondering why certain tests using several external, fixed libraries
would fail only with Meson and not with CMake or manual runs.
It turned out mtest.py enables MALLOC_PERTURB_ by default, which is
surprising--a topic for another Issue/PR.
At least, this surprising default is documented with workarounds.
In qemu, minikconf generates a depfile that meson could use to
automatically reconfigure on dependency change.
Note: someone clever can perhaps find a way to express this with a
ninja rule & depfile=. I didn't manage, so I wrote a simple depfile
parser.
As a newcomer to the Meson build system, I found the documentation of the `library()` function to be a bit misleading. Eventually I found what 'user option' referred to after digging through the docs.
This just adds a link back to the page that describes the options that are referred to in this paragraph.
Currently InternalDependency.get_partial_dependency shadows the the
input variables names, and then passes those new copies to the final
object returned. It also passes them to the arguments of of
get_partial_dependency for each subdependency, which is wrong. The
code is supposed to proxy the original argumetn values to that instead
of the shadowing values.
To avoid that this patch renames the new values.
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.
