When reverting from 0.57 to 0.56, one can see an error like this:
File /Users/pm215/src/qemu-for-merges/meson/mesonbuild/coredata.py,
line 1016, in load
obj = pickle.load(f)
ModuleNotFoundError: No module named 'mesonbuild.mesonlib.universal';
'mesonbuild.mesonlib' is not a package
FAILED: build.ninja
The reason is that the old version fails to resolve mesonbuild.mesonlib,
which is a similar situation to the existing AttributeError check. Raise
a MesonException for ModuleNotFoundError as well, so that reconfiguration
proceeds using cmd_line.txt.
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 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 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).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
This is useful for figuring out what kind of option this is. My hope is
that in the longterm this is less useful, but we'll still want it for
the configuration summary printing.
This is a complex key that can store multiple bits of data in a single
place. It can be generated from a command line formatted string, and
it's str method returns it to that form.
It's intentionally immutable, use the evolve() method to create
variations of an existing key.
This is consistent with c_args in machine file overriding CFLAGS from
env. This also spotted an issue where in a native build this resulted
in pkg_config_path being /bar instead of /foo:
`-Dpkg_config_path=/foo -Dbuild.pkg_config_path=/bar`
Fixes: #7573
It is much easier to not try to parse options into complicated
structures until we actually collected all options: machine files,
command line, project()'s default_options, environment.
Currently if you change the `choices` field in the meson_options.txt
file, no update will be done until `meson setup --wipe` is called. Now
if the choices change then the options will be properly merged.
If the currently select value is still valid it is guaranteed to be
kept, if it is now invalid the new default value will be used and a
warning will be printed.
Fixes#7386
This is required to make the various keys in the [user options] section
work the same as they do in the meson_options.txt file, where we don't
have any rules about case sensitivity.
There is some risk here. Someone may be relying on this lower by default
behavior, and this could break their machine files.
Fixes#7731
So that we can actually use it anyplace that an OptionDictType could be
used. I've also done a bit optimizing/simplifying of the implementation.
This is needed for cuda, as it returns an OptionOverrideProxy where we
ask for an OptionDicType
Instead of the default ones, this is especially important when cross
compiling or when using compilers that aren't compatible with the
default ones.
squash! dependencies/hdf5: Use the actual system compilers
Currently we do some crazy hackery where we add extra properties to a
Popen object and return that. That's crazy. Especially since some of our
hackery is to delete attributes off of the Popen we don't want. Instead,
let's just have a discrete type that has exactly the properties we want.
There is nothing to "warn" about, this is a completely routine
occurence. OTOH, when something is corrupted, we should warn. Keep
the red color and "WARNING:" prefix in that case.
Example output:
$ ninja -C build
Regenerating configuration from scratch: Build directory has been generated with Meson version 0.55.999, which is incompatible with current version 0.56.0.
The Meson build system
Version: 0.56.0

This creates a full set of option in environment that mirror those in
coredata, this mirroring of the coredata structure is convenient because
lookups int env (such as when initializing compilers) becomes a straight
dict lookup, with no list iteration. It also means that all of the
command line and machine files are read and stored in the correct order
before they're ever accessed, simplifying the logic of using them.
This puts all of them together, in the next patch they'll be pulled back
out, but it's convenient to start that refactor by moving them all
there, then moving them into env as a whole.
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
