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

In commit 8da060706c2c34fbea91898509123cb190894f3e we fixed an issue
where stashing would ignore untracked files, potentially conflicting
with what we reset to.
Unfortunately in the process it broke the functionality entirely, by
producing an invalid git command... according to some versions of git.
This is actually a git bug, fixed upstream in git 2.37.0 via commit
b02fdbc80a41f73ceb6c99e8e27b22285243a335. It causes git itself to
re-synthesize the command line for a negation pathspec with a "."
rather than "", as that's what is needed to make it match all files
other than the negation.
For backwards compatibility to older versions of git, we manually pass
the dot pathspec ourselves.

Previously, the VS backend would add the the include directories
in the reverse order that the Ninja backend does it, which
means that the source directories would be preferred over
the build directories. For example, this would cause the
compiler to choose the file from the source directory
if a file with the same name is found in both.
Fixes 57ec097b5 ("vs: Use CompilerArgs() for compile and link args")
Fixes #11630

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.

Also prevent from using a parent directory as builddir by mistake.

- MesonException for errors is clearer than SystemExit('error message')
and provides meson-formatted "ERROR: ..."
- `raise SystemExit` with no parameter isn't obvious that it intends to
exit successfully
While clarifying the latter, it was observed to cause
test_preprocessor_checks_CPPFLAGS() failure to be ignored. That test
checks get_define() on both c and cpp compilers, which means we need to
define either CPPFLAGS or both CFLAGS+CXXFLAGS.

This is a regression from #11537.

We need to remember its value when reconfiguring, but the Build object
is not reused, only coredata is.
This also makes CLI more consistent by allowing `-Dvsenv=true` syntax.
Fixes: #11309

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

pyconfig.h defines it in limited cases, but as empty, rather than as "1"
which is what command-line defines generally do. Explicitly define it as
a compatible definition so the compiler does not log a warning that the
value has changed.

Because we poke around with the dependency, so we might introduce some,
and have at least once.

The title is used only in the sidebar. There is no need to have
"extends" information there. For returned objects the actual name is not
meaningful so it's better to use the long name. For builtin objects the
name is important because that's the global variable name.

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 6aeec808367f05463394e30a8d40834e97c7afc0,
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

We embed the route to executing meson in various cases, most especially
regen rules in build.ninja. And we take care to ensure that it's a
canonicalized path. Although the code has moved around over time, and
adapted in ways both bad and good, the root of the matter really comes
down to commit 69ca8f5b544f700210d9f18613311bcce3c2e37a which notes the
importance of being able to run meson from any location, potentially
not on PATH or anything else.
For this reason, we switched from embedding sys.argv[0] to
os.path.realpath, a very heavy stick indeed. It turns out that that's
not actually a good thing though... simply resolving the absolute path
is enough to ensure we can accurately call meson the same way we
originally did, and it avoids cases where the original way to call meson
is via a stable symlink, and we resolved a hidden location.
Homebrew does this, because the version of a package is embedded into
the install directory. Even the bugfix release. e.g.
```
/opt/homebrew/bin/meson
```
is symlinked to
```
/opt/homebrew/Cellar/meson/1.0.0/bin/meson
```
Since we went beyond absolutizing the path and onwards to canonicalizing
symlinks, we ended up writing the latter to build.ninja, and got a
"command not found" when meson was upgraded to 1.0.1. This was supposed
to work flawlessly, because build directories are compatible across
bugfix releases.
We also get a "command not found" when upgrading to new feature
releases, e.g. 0.64.x to 1.0.0, which is a terrible error message. Meson
explicitly "doesn't support" doing this, we throw a MesonVersionMismatchException
or in some cases warn you and then effectively act like --wipe was given.
But the user is supposed to be informed exactly what the problem is, rather
than getting "command not found".
Since there was never a rationale to get the realpath anyways, downgrade
this to abspath.
Fixes #11520

I've left the old release notes in place, but updated everything else to
use `meson.options`
|
|
We will still try to load `meson_options.txt` if `meson.options` doesn't
exist. Because there are some advantages to using `meson.options` even
with older versions of meson (such as better text editor handling)
we will not warn about the existence of a `meson.options` file if a
`meson_options.txt` file or symlink also exists.
The name `meson.options` was picked instead of alternative proposals,
such as `meson_options.build` for a couple of reasons:
1. meson.options is shorter
2. While the syntax is the same, only the `option()` function may be
called in meson.options, while, it may not be called in meson.build
3. While the two files share a syntax and elementary types (strings,
arrays, etc), they have different purposes: `meson.build` declares
build targets, `meson.options` declares options. This is similar to
the difference between C's `.c` and `.h` extensions.
As an implementation detail `Interpreter.option_file` has been removed,
as it is used exactly once, in the `project()` call to read the options,
and we can just calculate it there and not store it.

This allows to run setup command regardless whether the builddir has
been configured or not previously. This is useful for example with
scripts that always repeat all options.
meson setup builddir --reconfigure -Dfoo=bar

CI runs with vs2019 and we were passing --backend=vs. This fix
reconfigure tests because we can't reconfigure with --backend=vs when
initial configuration determined the backend is actually vs2019.

When running tests on Windows (or for devenv), paths of shared
libraries need to be added to the PATH envvar for Windows to
be able to find them. Meson is currently using the path of the
import lib, which is wrong in many cases.
This fix does two things: if there is a variable bindir
in the pkg-config file, those variable
values are added to the list of path. This is for conan
dependencies, if conan decides to export those paths.
See https://github.com/conan-io/conan/issues/13532 .
The fallback is to replace `lib` by `bin` in the import
library path. This heuristic will work most of the time
(but the bin directory could have a different name,
or the dll itself could have a different name). In all cases,
it cannot be worse than current implementation, and it
solves many cases.

It was totally subproject-unsafe, and setting a super bad example. This
is bad, because doxygen is annoying to get right and we occasionally
tell people to go use our example test case.
There is a fun nuance here, that makes doxygen unpredictably work on
some versions, and fail on others. Specifically, values must be quoted
in doxygen 1.8, but not in doxygen 1.9, or they break -- but only if the
output directory contains spaces. This was "fixed" in commit
https://github.com/doxygen/doxygen/commit/ef91bacb7a69bbf7bccb4a864698cc003aabac66
which actually caused it to act like an unquoted OUTPUT_DIRECTORY is not
provided at all, and then fixed for real in commit
https://github.com/doxygen/doxygen/commit/eb3d1eb5ad85c94d6f2c32934fce2b8630331d6c
For portability, it is necessary to quote this just to be on the safe
side.

It can only be used for projects that don't have any rules at all, i.e.
they are purely using Meson to:
- configure files
- run (script?) tests
- install files that exist by the end of the setup stage
This can be useful e.g. for Meson itself, a pure python project.

In commit faf79f4539841cbf89fe8d53cf35aa91fd8273c9 we broke this utility
function by referencing a non-existent variable. Fortunately, the only
time we ever used said function was once, and that in a test case where
we tested that it raised a MesonException before the undefined variable
error could occur.
|
|
What we are mainly doing here is checking that the options make sense,
or fixing that up if they don't. And in the next commit we will want to
do that by also checking the build object.
