Currently, if we run "meson configure -Doption=value", meson will
do a reconfigure when running "ninja build" afterwards, even if
the new value is the same one that was already configured previously.
To avoid this unnecessary reconfigure, let's use replace_if_different()
instead of unconditionally replacing the conf file in coredata's save()
function.
When need to catch exceptions just like we do in coredata.load() to
print proper error message instead of backtrace when user mix meson
versions.
This happens frequently when user has a newer version of meson installed
in their HOME and then "sudo meson install" uses the system version of
meson.
By default, meson will try to look for shared libraries first before
static ones. In the meson.build itself, one can use the static keyword
to control if a static library will be tried first but there's no simple
way for an end user performing a build to switch back and forth at will.
Let's cover this usecase by adding an option that allows a user to
specify if they want dependency lookups to try static or shared
libraries first. The writer of the meson.build can manually specify the
static keyword where appropriate which will override the value of this
option.
If set to true it will generate the pkgconfig files as relocatable i.e
the prefix variable will be relative to the install_dir. By default
this is false.
Will generate a MesonException if the pkgconfig file is installed
outside of the package and pkgconfig.relocatable=true.
It is always used as an immutable view so there is no point in doing
copies. However, mypy insist it must implement the same APIs as
Dict[OptionKey, UserOption[Any]] so keep faking it.
When reverting from 0.62 to 0.59, one can see an error like this:
line 1003, in load
obj = pickle.load(f)
File "/Users/pm215/src/qemu-for-merges/meson/mesonbuild/mesonlib/universal.py",
line 2076, in __setstate__
self.__init__(**state) # type: ignore
TypeError: __init__() got an unexpected keyword argument 'module'
FAILED: build.ninja
Raise a MesonException for TypeError as well, so that reconfiguration
proceeds using cmd_line.txt.
A bunch of files have several T.TYPE_CHECKING blocks that each do some
things which could just as well be done once, with a single `if`
statement. Make them do so.
The default behavior of installing relative to prefix may be unexpected,
and is definitely wrong in many cases.
Give users control in order to specify that yes, they actually want to
install to a venv.
This is particularly useful for projects that use meson as a build
system for a python module, where *all* files shall be installed into
the python site-packages.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

In commit e5a6283c4c, this function was
reorganized to assign value -> newvalue instead of overwriting newvalue,
but the error message case wasn't updated to match. As a result,
actually hitting the error would report an even more errory error, i.e.
a traceback.
(Actually hitting the error requires passing an array option as a python
object that isn't a list or a string. This is impossible to do from the
command line or meson_options.txt, but can be done with builtin options.)
It can be either:
- boolean: the option is completely deprecated.
- list: some choices are deprecated.
- dict: some choices are deprecated and replaced by another.
Fixes: #7444
Remove test_minor_version_does_not_reconfigure_wipe() because when run
during dev cycle that test reconfigure with .99 -> .100 which is
considered a major version change now. It is covered by a more efficient
internal test now anyway.
While at it, remove no-op `with Path(self.builddir):` statement, the
intention was clearly to set workdir.
Fixes: #9260
It is a commonly needed information to help debugging build issues. We
already were printing options with non-default value at the end of the
configure but outside of the summary.
Keeping the list of user defined options in the interpreter will also in
the future be useful to use new default value on reconfigure.
We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
