has_function() tries to link an example program using the function
to see if it is available, but with clang on 64bit Windows this
example always already failed at the compile step:
error: cast from pointer to smaller type 'long' loses information
long b = (long) a;
This is due to long!=pointer with LLP64
Change from "long" to "long long" which is min 64bit and should always
fit a pointer. While "long long" is strictly a C99 feature every
non super ancient compiler should still support it.

Currently deprecation features use the same logic as new features, but
that doesn't work correctly. FeatureNew wants to warn about cases where
you claim to support >= 0.40, but use a feature from 0.42; deprecation
wants to warn when you claim to support >= 0.50, but use a feature that
was replaced in 0.45.
To make this work we need to invert the version check in the deprecation
function, so that if the deprecation is 0.45, and the supported version
is >= 0.50, we get a true not a false.

Currently The Deprecated and New features checkers share an attribute
through a base class that should be per class. We need to duplicate this
and move it into each of the sublcasses

The system tool is always the wrong thing to use and cause hard to debug
issues when trying to link system libraries with cross built binaries.
The ExternalDependency base class already had a method to deal with
this, used by PkgConfigDependency and QtBaseDependency, so it should
make things more consistent.

The builtin check had a special case that if a header was provided and
the function wasn't defined, it would ignore the builtin to avoid
non-functional builtins (for example __builtin_posix_memalign in MSYS2).
GCC 10 gained support for __has_builtin() which now skipps this check
and because __has_builtin(__builtin_posix_memalign) returns true the
non functional builtin is now reported as available.
To get the old behaviour back move the special case in front of the actual
availability check.
Fixes #7113

As stated by the doc, default to install python sources to purelib
location, as they should not depend on platform.
This also fixes discrepancy between get_install_dir() and
install_sources() locations.

Discussions in #6524 have shown that there are various possible uses of the
kconfig module and even disagreements in the exact file format between
Python-based kconfiglib and the tools in Linux. Instead of trying to
reconcile them, just rename the module to something less suggestive and
leave any policy to meson.build files.
In the future it may be possible to add some kind of parsing through
keyword arguments such as bool_true, quoted_strings, etc. and possibly
creation of key-value lists too. For now, configuration_data objects
provide an easy way to access quoted strings. Note that Kconfig stores
false as "absent" so it was already necessary to write "x.has_key('abc')"
rather than the more compact "x['abc']". Therefore, having to use
configuration_data does not make things much more verbose.

This is useful when one needs to force meson to use wrappers for cross
compilation.

The comment for this code is correct, but the code itself isn't. The way
it's implemented in a cross compile we don't look at PKG_CONFIG_PATH at
all.

Add support for Gtest as a test protocol
|
|
Revert cross fixup
|
|
|
|
|
|
Gtest can output junit results with a command line switch. We can parse
this to get more detailed results than the returncode, and put those in
our own Junit output. We basically just throw away the top level
'testsuites' object, then fixup the names of the tests, and shove that
into our junit.

It's not a boolean, so let's avoid initializing it to invalid choices
followed by assigning it valid ones.

* WIP: Document formal Meson grammar
* Various little fixes [skip ci]
1) Add missing logical_not_expr
2) 'in' and 'not in' are valid relational operators at least for dicts
3) dictionary keys can be expressions, but kwarg names cannot
4) typo logical_end_expression -> logical_and_expression
5) Make jump statements only allowed inside an iteration statement
* Rework EBNF style [skip ci]
As there is no good order for the productions, just go alphabetically.
The EBNF style was changed to match the one the Python lark project
uses, that is colons for productions and terminals enclosed in double
quotes.
* Add missing production for unary operators [skip ci]
* Add production for multiline strings [skip ci]
* Properly define terminal symbols [skip ci]
Depending on the EBNF flavor, regex can be used to describe the terminal
symbols. Lark allows this, and as it was mentioned as a possible user of
this grammar, let's follow its flavor here. Most regexes used are easily
human-readable, and we can always add comments to more complicated ones.
* Small changes to which expressions can be used where [skip ci]
Let the grammar be very general. The type system then has to check, that
the used expression really evaluates to the correct type. Even if we
know today that assignment expressions always evaluate to None (and can
therefore only be used as a toplevel expression in an expression
statement), this needn't be the case forever. So this way, the grammar
stays stable even if such changes were made.
* Rework function argument list production [skip ci]
* Be more verbose for production names [skip ci]
Rename expr -> expression, stmt -> statement, op -> operator, program ->
build_definition. Also adjust some list productions.
* Add paragraph about syntax stability promises [skip ci]

This gives us better type safety, and will be important as we add more
test methods

Update the test.json schema, adding the 'stdout' property.
Also amend the test.json schema so the presence of an unexpected
property on the root object causes a validation error.
v2:
Also add 'tools' property to json schema.
Amend the documentation not to use the word 'list' to describe a dict.
|
|
Update dircondenser.py tool to update paths appearing in the expected
stdout in test.json when the containing directory is renamed.
|
|
Initially produced using:
for d in "test cases/failing/"* ; do rm -r _build ; ./meson.py setup "$d" _build | grep ERROR >"$d"/expected_stdout.txt; done
then converted to json with jq using:
jq --raw-input --slurp 'split("\n") | {stdout: map({line: select(. != "")})}' expected_stdout.txt >test.json
or merged with existing json using:
jq --slurp '.[0] + .[1]' test.json expected.json >test.json.new
v2:
Add some comments to explain the match when it isn't totally obvious
v3:
Add or adjust existing re: in expected output to handle '/' or '\' path
separators appearing in message, not location.
v4:
Put expected stdout in test.json, rather than a separate expected_stdout.txt file
Park comments in an unused 'comments' key, as JSON doesn't have a syntax for comments
|
|
Expected stdout lines must match lines from the actual stdout, in the
same order. Lines with match type 're' are regex matched.
v2:
Ignore comment lines in expected_stdout
v3:
Automatically adjust path separators for location in expected output
v4:
Put expected stdout in test.json, rather than a separate file
|
|
Cosmetic tweak to the error message for incdir() with an absolute path.
Don't split the message in the middle of a sentence at a point which may
or may not correspond to the terminal width.
|
|
For the sake of a consistent error message (irrespective of if 'valac' is
present or not), check if the 'c' language is present if we are adding
'vala' before (rather than after) we do compiler detection.
|
|
Generally, we'd want to use str() rather than repr() in error messages
anyhow, as that explicitly gives something designed to be read by
humans.
Sometimes {!r} is being used as a shortcut to avoid writing the quotes
in '{!s}'.
Unfortunately, these things aren't quite the same, as the repr of a
string containing '\' (the path separator on Windows) will have those
escaped.
We don't have a good string representation to use for the arbitrary
internal object used as an argument for install_data() when it's neither
a string nor file (which doesn't lead to a good error message), so drop
that for the moment.

Currently, colourize_console is a constant, set at process
initialization.
To allow the actual stdout to be easily compared with the expected when
running tests, we want to allow colourization to be on for the test
driver, but not for the in-process configure done by run_configure,
which has stdout redirected from a tty to a pipe.
v2:
Cache _colorize_console per file object
v3:
Reset cache on setup_console()
