There are still caveats here. Rust/cargo handles generated sources by
writing out all targets of a single repo into a single output directory,
setting a path to that via a build-time environment variable, and then
include those files via a set of functions and macros. Meson's build
layout is naturally different, and ninja makes working with environment
variables at compile time difficult.
Fixes#8157
we have two functions to do the exact same thing, and they're basically
implemented the same way. Instead, let's just use the BuildTarget one,
as it's more generally available.
The /ZI flag adds in "Edit and Continue" debug information, which will
cause massive slowdown. It is not a flag that we should be adding by
default to debug builds.
/Zi will still be added.
Move the logic to start the read/decode
tasks to TestSubprocess and keep SingleTestRunner simple.
The lines() inner function is tweaked to produce stdout as a future.
This removes the nonlocal access (which is not possible anymore
when the code is moved out of _run_cmd), and also lets _run_cmd
use "await stdo_task" for both parsed and unparsed output.
After the next patch, we will need to complete parse_task before
stdo_task (because parse_task will not set the "stdo" variable
anymore but it will still collect stdout just like now). Do
the change now to isolate the more complicated changes.
The new behavior of interrupting the longest running test with Ctrl-C is useful
when tests hang, but not when the run is completely broken for some reason.
Psychology tells us that the user will compulsively spam Ctrl-C in this case,
so exit if three Ctrl-C's are detected within a second.
Add a new attribute to an object outside of the initializer of
construtor is considered an antipattern for good reason, it's gross,
it's confusing, and it often leads to AttributeErrors down some paths.
Let's not do that.
This adds annotations and fixes a couple of issues (passing Set[bytes]
where List[byte] is expected), however, there's some very gross addition
of attributes to types going on that I haven't fixed yet, and mypy is
very grump about.
This adds enough type annotations for InstallData and friends to make
minstall happy. There is also a small change in that I've replaced the
List[List] with List[Tuple], as tuples are more appropraite data types
for the information (fixed length, position matters, different types at
different indexes)
Currently InstallDir is part of the interpreter, and is an Interpreter
object, which is then put in the Build object. This is a layering
violation, the interperter should have a Holder for build data. This
patch fixes that.
It's only used for doing an `if x in container` check, which will be
faster with a set, and the only caller already has a set, so avoid
we can avoid a type conversion as well.
glob.glob() is not sorted, despite using shell-style wildcards, and the
documentation does not mention this: https://bugs.python.org/issue21748
Recently, it does start mentioning "Whether or not the results are
sorted depends on the file system." which does not really get to the
heart of the matter...
This is causing fuzz too.
aligning along the left is, I think, what most projects want to do.
Aligning along the middle looks subjectively ugly, and objectively
prevents me from further indenting an element, e.g.
Build information:
prefix : /usr
sysconfdir : /etc
conf file : /etc/myprogram.conf
The current way this works is chaos since the tool might return files in
any order and thus shuffle around the order of embedded files. This
results in big diffs that cannot be easily reviewed.
Also regenerate the data according to the, going forward, canonical
ordering algorithm.
Currently we use the mesonlib ones, but these are always the build
machine definitions, rather than being available for either the build or
host machine. We already have an `Environment` instance, and the correct
`MachineChoice`, so lets use that.
Fixes#8165
A sub-subproject can be configured directly from
`subprojects/foo/subprojects/bar/` in the case `bar` is in the same git
repository as `foo` and not downloaded separately into the main
project's `subprojects/`. In that case the nested subproject violation
code was wrong because it is allowed to have more than one "subprojects"
in path (was not possible before Meson 0.56.0).
Example:
- self.environment.source_dir = '/home/user/myproject'
- self.root_subdir = 'subprojects/foo/subprojects/bar'
- project_root = '/home/user/myproject/subprojects/foo/subprojects/bar'
- norm = '/home/user/myproject/subprojects/foo/subprojects/bar/file.c'
We want `norm` path to have `project_root` in its parents and not have
`project_root / 'subprojects'` in its parents. In that case we are sure
`file.c` is within `bar` subproject.
This function returns both the name and the value, but we never actually
use the name, just the value. Also make this module private. We really
want to keep all environment variable reading in the Environment class
so it's done once up front. This should help with that goal.
This both moves the env reading to configuration time, which is useful,
and also simplifies the implementation of the boost dependency. The
simplification comes from being able to delete basically duplicated code
since the values will be in the Properties if they exist at all.
This has a bunch of nice features. It obviously centralizes everything,
which is nice. It also means that env is only re-read at `meson --wipe`,
not `meson --reconfigure`. And it's going to allow more cleanups.
This is PEP8 convention for a const variable. Also, make the type
Mapping, which doesn't have mutation methods. This means mypy will warn
us if someone tries to change this.
This causes the variable to be read up front and stored, rather than be
re-read on each invocation of meson.
This does have two slight behavioral changes. First is the obvious one
that changing the variable between `meson --reconfigure` invocations has
no effect. This is the way PKG_CONFIG_PATH already works. The second
change is that CMAKE_PREFIX_PATH the env var is no longer appended to
the values set in the machine file or on the command line, and is
instead replaced by them. CMAKE_PREFIX_PATH is the only env var in meson
that works this way, every other one is replaced not appended, so while
this is a behavioral change, I also think its a bug fix.
