Allow macro_name to be speficied as a parameter to configure_file().
This allows C macro-style include guards to be added to
configure_file()'s output when a template file is not given. This change
simplifies the creation of configure files that define macros with
dynamic names and want the C-style include guards.
- On Windows, it was not detected if include directory was an absolute
path to source directory, because of the mis of path separators.
- In the edgecase the include directory begins with the exact same
string as the source directory, but is a different directory, it was
falsely reported as an error.
Fixes#12217.
Adds a new method to the compiler object, has_define.
This makes it possible to check if a preprocessor macro/define
is set or not.
This is especially helpful if the define in question is empty,
for example:
#define MESON_EMPTY_DEFINE
This would yield the same results as a missing define with
the existing get_define method, as it would return an empty
string for both cases. Therefore this additional method is
needed.
This reverts commit f52bcaa27f.
It did not pass CI, and was merged anyway because there were two CI
errors in the same cygwin job. The other error was not the fault of this
commit, and since cygwin errors were glossed over because they were
"expected", the presence of a new error *added* by this commit was
overlooked.
Per the meson development policy, PRs which result in CI errors
can/should be reverted at will, no questions asked.

We support this in a machine file:
```
[binaries]
pkgconfig = 'pkg-config'
pkg-config = 'pkg-config'
```
and you can use either one, because internally we look up both. If you
only set *one* of them, this plays awkwardly with setting $PKG_CONFIG,
since we don't know which one you set in the machine file and the
*other* one will be initialized from the environment instead.
In commit 22df45a319 we changed program
lookup of config-tool style dependencies to use the regular tool names
and only fall back on the strange internal names. This affected the
pkg-config class too.
The result is that instead of preferring `pkgconfig =` followed by
$PKG_CONFIG followed by `pkg-config =`, we inverted the lookup order.
This is a good idea anyway, because now it behaves consistently with
`find_program('pkg-config')`.
Unfortunately, we documented the wrong name in a bunch of places, and
also used the wrong name in various testsuite bits, which meant that if
you set $PKG_CONFIG and then ran the testsuite, it would fail.
Correct these references, because they are buggy.
One test case expected to find_program() a native copy for convenience
of testing against natively installed glib. Force it to resolve a native
copy.
This fixes two issues in constructing the default installation path
when install_dir is not specified:
- inside a subproject, install_data() would construct the destination
path using the parent project name instead than the current project
name,
- when specifying preserve_path, install_data() would construct the
destination path omitting the project name.
Fixes#11910.
In order to pass a File object down into the compiler impl and compile
it, we cannot pass a string with the filename, and we cannot either pass
the File object as-is, since it relies on being given Environment
attributes to calculate the relative location. So we build a fresh File
object as an absolute path.
But the code to do this was totally broken. Instead of using the File
method to get an absolute path, we used one that expected to create
builddir-relative paths... and then gave it the absolute source dir as
the "relative path portion" prefix. This worked by accident as long as
it wasn't a built File, but if it was a built file then we intentionally
didn't include that prefix -- which was wrong anyway, since we need the
build directory!
Use the correct method to get an absolute path in all cases, and emit a
warning if it was a built file. This never worked. Sometimes it crashed,
sometimes it silently returned false.
Fixes#11983
By specifiying explicit encodings, we can silence warnings like:
/__w/meson/meson/test cases/common/100 postconf with args/postconf.py:15: EncodingWarning: 'encoding' argument not specified
with open(input_file) as f:
in CI.
The new splitlines method on str is intended to replace usage of
fs.read('whatever').strip().split('\n').
The problem with the .strip().split() approach is that it doesn't have a
way to represent empty lists (an empty string becomes a list with one
empty string, not an empty list), and it doesn't handle Windows-style
line endings.
For all source `*.py` files installed via either py.install_sources() or
an `install_dir: py.get_install_dir()`, produce `*.pyc` files at install
time. Controllable via a module option.
If the optional first "mainlib" argument is there, then we infer several
values. Otherwise, some of those values fall back to a generic default,
and two of them -- name and description -- fall back to being mandatory.
In commit e84f293f67, we removed
validation for description as part of refactoring that never actually
validated anything.
The paths in meson.build use / as path separator, however, the paths
constructed during the directory structure walk use native path
separators, thus the path never compare equal to the excluded ones.
Normalize the exclusion paths before the comparison.
During evaluation of codeblocks, we start off with an iteration of
nodes, and then while evaluating them we may update the global
self.current_node context. When catching and formatting errors, we
didn't take into account that the node might be updated from the
original top-level iteration.
Switch to formatting errors using self.current_node instead, to ensure
we can point at the likely most-accurate actual cause of an error.
Also update the current node in a few more places, so that function
calls always see the function call as the current node, even if the most
recently parsed node was an argument to the function call.
Fixes#11643
Extend the "common/include order" test to ensure that the build
directory is preferred over the source directory. For example,
when using `configure_file()`, the resulting file should be
preferred over a file with the same name in the source directory.
Allows getting closer to `./run_project_tests.py -- -Dwerror=true`.
- when argc and argv are not *both* used, there's a standard, compliant
mechanism to mark the variable as unused
- generated code should not build as -Werror
- more thoroughly comment out some commented code
Because we base the pickled data name on the name property of the
command being run... and for built targets, `exe.name` is always just
the name. However, for an ExternalProgram this is just whatever string
we searched for, so, NOT just the basename.
This became a bigger issue once we started using generator() with the
actual program in commit 6aeec80836,
rather than first casting it to a string, because the VS backend
*always* uses the meson_exe approach for various reasons related to VS
being VS.
Outside of that, it's difficult to actually get an ExternalProgram
object passed to meson_exe -- CustomTarget lowers it to a string,
capture is handled via argparse instead of pickling, etc.
Fixes#11593
This test is intended to test really long output, so it prints 100k
lines of stdout/stderr. It completes in two seconds on my machine, but
the default 30-second timeout is apparently too much for CI, because on
Windows we often get flaky tests due to this. e.g. we'll get within 200
lines of the end.
Bump the CI time by x2. We know this isn't particularly surprising
behavior, and allowing it to request another 30 seconds won't hang the
CI. But it will save us from some spurious failures and restarted jobs.
In commit eaf365cb3e we explicitly sorted
them for neatness, with the rationale that we were restoring intentional
behavior and we only need a set for stylistic purposes.
This actually wasn't true, because we never sorted them to begin with
(we did sort the version numbers), but sorting them is fine. The bigger
issue is that we actually used a set to avoid printing the same feature
type multiple times. Now we do print them multiple times -- because each
registered feature includes the unique node.
Fix this by using both sorted and a set.
Fix tests that should in retrospect have flagged this as an issue, but
were added later on in the same series to check something else entirely,
happen to cover this too, and were presumably copied directly from
stdout as-is...
We need to know the project minimum version before evaluating the rest
of the function. There's three basic approaches:
- try to set it inside KwargInfo
- just run a minimal version of func_project for this, then load
everything after
- drop down to the AST and set it before anything else
In order to handle FeatureNew emitted by a FunctionNode evaluated
before project() due to being inlined, such as `version: run_command()`,
only option 3 suffices, the rest all happen way too late. Since we have
just added AST handling support for erroring out, we can do that to set
the version as well.
