Do not traceback when trying to update a wrap that isn't a [wrap-file],
just report the problem.
Do not traceback on perfectly valid WrapDB wraps that don't have a
patch_url because they have upstream meson.build, instead try to parse
the version from the source tarball filename.
There's no reason it needs a concrete list, any iterable is fine. This
does mean that we need to explicitly check for `str | bytes` in the
listify pass, as `str` and `bytes` are both iterable.
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.
For a test to be displayed to stdout without buffering, it has to be
1) in verbose mode 2) not executed in parallel with others
3) not parsed, i.e. not TAP or Rust. Include these three
conditions in a new property of stdout and use it in the
three places where it matters: when printing the initial
and final delimiters of the output, and when deciding the
console mode to use.

Currently it tries to run "cmd" by default in a MSYS2 bash.
Passing "bash" doesn't work since that defaults to WSL and
one has to pass an absolute path to bash instead, and even then
one misses out on the PS1 override.
In case $SHELL is set and the contained path exists prefer it even if
we are on Windows.
To make the PS1 override work we can't use Unix paths in Python since
we might be on Windows, so move the .bashrc check into the temporary
bash script itself.
This makes "meson devenv" work the same under MSYS2 as on Linux.
If --no-rebuild is used, the test program might not exist, spawning a
FileNotFoundError inside a long traceback rooted in subprocess.Popen
trying to run that test program. Current versions of Meson even say it's
an "unhandled python exception".
But we can do one better and actually tell the user what is wrong, why,
and what to do to fix it. And we can do so before getting waist deep in
partially running tests.
Fixes#10006
Verbose, non-parallel tests generally print their output as they run, rather than
after they finish. This however is not the case if stdout of the test is parsed
as is the case for TAP and Rust tests. In this case, the output during the run
is the list of the subtests, but stderr still has to be printed after the test
finishes.
This header is required anyway. And the compile test for linking to libc
with the gettext symbol, can succeed when we try to use the literal
symbol name without includes, but fail later during project build,
because actually including libintl.h might redefine the function to match
a forked symbol. This happens when GNU libintl is installed as a
standalone library on systems that have a less fully-featured gettext
implementation.
So, by including the header in has_function, we can ensure that we test
against the default resolved header. In the event that the symbol which
is #define'd by the header is 'libintl_gettext', linking will fail against
libc even when a builtin gettext does exist, and we will fall back to the
intl dependency that provides -lintl (and which is needed to properly
use the default header).
Of course, even that probably won't work.
has_function(prefix: '...') is useless to check the difference between
builtins and external library functions. It has code to detect
"builtins" that misfires in some cases (previously seen with iconv_open).
Instead compile an open-coded test file that this intl dependency
implementation fully controls, that doesn't get up to imaginative edge
cases like trying to find `__builtin_gettext`.
It's the only way to be sure.
Fixes compiling against the intl dependency on e.g. Alpine Linux when the
libintl package is installed.
Given a meson.build with the contents:
```
t = '
'
```
We want to warn that this is bad. So we emitted this warning:
```
WARNING: Newline character in a string detected, use ''' (three single quotes) for multiline strings instead.
This will become a hard error in a future Meson release. t = ' 4 4
```
The line contents and the offset are printed as gibberish after a big
whitespace run. These are elsewhere often passed to ParseException,
which pretty-prints this, but newlines aren't an exception, merely a
warning, and mlog.warning doesn't accept numeric strings as anything
more meaningful than something to print as text.
Fix this (by wrapping it in a ParseException) to properly print:
```
meson.build:4: WARNING: Newline character in a string detected, use ''' (three single quotes) for multiline strings instead.
This will become a hard error in a future Meson release.
t = '
^
```
A backslash-escape of the last newline before a run of whitespace
leading to the indented string ending and function termination `)` does
not actually escape the entire line and make it do nothing. In fact what
it does is cause all that whitespace to be part of the preceding line,
and get printed.
Meanwhile the textwrap.dedent documentation states that lines with only
whitespace get normalized. When you *don't* mess with that final line,
dedent actually does the right thing and makes the output message end
with a single newline after the important text.
Do not report a MesonBugException if the command is `runpython`, because
that is 100% other people's code, not ours. It's only used as an
alternative to sys.executable for reporting a path to python, in the
event of a Windows MSI install.
While we are at it, refactor the logic for PermissionError to be a bit
more unified (and sadly use isinstance instead of except, but it is what
it is).
Automatically generate additional variables and write them into the
generated pkg-config file.
This means projects no longer need to manually define the ones they
use, which is annoying for dataonly usages (it used to forbid setting
the base library-relevant "reserved" ones, and now allows it only for
dataonly. But it's bloat to manualy list them anyway).
It also fixes a regression in commit
248e6cf473 which caused libdir to not be
set, and to be unsettable, if the pkg-config file has no libraries but
uses the ${libdir} expansion in a custom variable. This could be
considered likely a case for dataonly, but it's not guaranteed.
Android requires shared modules that use symbols from other shared
modules to be linked before they can be dlopen()ed in the correct
order. Not doing so leads to a missing symbol error:

We need to always allow linking for this. Also add a soname, although
it's not confirmed that it's needed, and it doesn't really hurt if it
isn't needed.
We currently cannot make this work because inside dependency() we don't
know the current subproject. We would also like the optional but
extremely useful location node, but we don't have that either...
Convert the broken code to a FIXME for visibility.
Use a derived type when passing `subproject` around, so that mypy knows
it's actually a SubProject, not a str. This means that passing anything
other than a handle to the interpreter state's subproject attribute
becomes a type violation, specifically when the order of the *four*
different str arguments is typoed.
On Windows using MSYS2 MinGW installing the package `mingw-w64-x86_64-wxmsw3.1` provides `wx-config-3.1`. I have tried building my software by making this exact change and it build correctly.
We do not want anyone touching this entire directory tree, but due to
the way it was implemented, we only checked if its direct parent was a
subproject violation. This generally worked, unless people tried to add
`subprojects/` as an include directory.
Patch this hole. It now provides the same warning any sandbox violation
does (but is not currently an error, just a "will become an error in the
future").
In commit b30dddd4e5, various refactorings
were done, during which a kwarg got accidentally dropped from the
function that determined part of the log message. As a result, a ':'
suddenly appeared in the log message where none should be.
Example expected output:
Checking if "-Werror=shadow with local shadowing" compiles: YES
What actually happened:
Checking if "-Werror=shadow with local shadowing" : compiles: YES
Fixes#9974
RuntimeError is way too generic when we have an explicit class for
"Meson reports to the user, something went wrong".
Moreover we now tell people that generic exceptions are "Meson bugs and
should be reported", so our failure to do the technically correct thing
and report the right kind of exception means we get haunted by demons of
confusion. Specifically, people complain to us that Meson told them
"there is a bug in Meson" when their install fails due to meson.build or
build environment issues.
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>.

This has never worked for built/found programs, only for script files.
In commit 2fabd4c7dc scripts learned an
attribute stating which subproject they came from. In commit
3990754bf5 dist scripts learned to run
even from a subproject, and relied on that attribute to know when, in
fact, they came from a subproject.
Unfortunately the original attribute was only set in one half of an
if/else, and the other half returned early with only part of the work
done.
