I ran into one of these from LGTM, and it would be nice if pylint could
warn me as part of my local development process instead of waiting for
the CI to tell me.
Instead of treating native files as always being for the build machine,
and then copying them to the host machine, treat them as for the build
machine only when a cross file is also present
They are supposed to have different behavior. The environment variables
apply to both the compiler and linker when the compiler acts as a
linker, but the command line ones do not.
Fixes#8345
Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
The script dir is never really used since meson --internal handles this.
The last remaining use of the raw script dir got removed in commit
522392e755.
All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
This did work previously, so we need to let it continue working. I'm
proposing removing it in 0.60 because the correct solution has always
worked.
I've also been a bit more defensive here, and made setting
`subproject:opt = foo` in the machine files an error, as we have
`[subproject:built-in options]` or `[subproject:project options]` for
that.
Or other language flags that use CPPFLAGS (like CXXFLAGS). The problem
here is actually rather simple, `dict.setdefault()` doesn't work like I
thought it did, I thought it created a weak entry, but it actually is
equivalent to:
```python
if k not in dict:
dict[k] = v
```
Instead we'll use an intermediate dictionary (a default dictionary
actually, since that makes things a little cleaner) and then add the
keys from that dict to self.options as applicable.

Currently mesonlib does some import tricks to figure out whether it
needs to use windows or posix specific functions. This is a little
hacky, but works fine. However, the way the typing stubs are implemented
for the msvcrt and fnctl modules will cause mypy to fail on the other
platform, since the functions are not implemented.
To aleviate this (and for slightly cleaner design), I've split mesonlib
into a pacakge with three modules. A universal module contains all of
the platform agnositc code, a win32 module contains window specific
code, a posix module contains the posix specific code, and a platform
module contains no-op implementations. Then the package's __init__ file
imports all of the universal functions and all of the functions from the
approriate platform module, or the no-op versions as fallbacks. This
makes mypy happy, and avoids `if`ing all over the code to switch between
the platform specific code.
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 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.
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
* environment.py: Detect all mips* architectures
We have more than those values, like:
mipsel
mipsel-nf
mips32el
mips33el-nf
mipsisa32r6
mipsisa32r6el
So lets just detect them all.
Sorry I forgot about 64bit and closed https://github.com/mesonbuild/meson/pull/8106
But now it even detects:
mipsisa64r6
mipsisa64r6el
* Make dcbaker happy
rustc is very different than other compilers, in that it doesn't
generate object files, it just creates a final target out of the
intermediate sources. As such, it needs to know about the linker args in
the compiler invocation.
