2023-12-13Use SPDX-License-Identifier consistentlyDylan Baker
This replaces all of the Apache blurbs at the start of each file with an `# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing uses to be consistent in capitalization, and to be placed above any copyright notices. This removes nearly 3000 lines of boilerplate from the project (only python files), which no developer cares to look at. SPDX is in common use, particularly in the Linux kernel, and is the recommended format for Meson's own `project(license: )` field
2023-05-16meson_exe: print suitable debug information for DLL not found errorsEli Schwartz
It's particularly inscrutable if you do not know where DLLs weren't found because you don't know what the PATH was in the child process.
2023-02-01treewide: add future annotations importEli Schwartz
2022-09-28Move classes used by scripts to their own moduleXavier Claessens
Those classes are used by wrapper scripts and we should not have to import the rest of mesonlib, build.py, and all their dependencies for that. This renames mesonlib/ directory to utils/ and add a mesonlib.py module that imports everything from utils/ to not have to change `import mesonlib` everywhere. It allows to import utils.core without importing the rest of mesonlib.
2022-09-22pylint: enable global-statementDylan Baker
This does force a number of uses of `# pylint: disable` comments, but it also finds a couple of useless global uses and one place (in the previous commit) that an easy refactor removes the use of global. Global is a code smell, so forcing adding a comment to disable helps force developers to really consider if what they're doing is a good idea.
2022-06-17Improve WINEPATH reductionXavier Claessens
- Remove duplicated code in mdevenv.py - Change the limit to 1024 instead of 2048 which is what has been tested. - Skip shortening if it is already short enough. - Skip shortening with wine >= 6.4 which does not seems to have that limitation any more. - Downgrade exception to warning in the case WINEPATH cannot be shortened under 1024 chars, it is possible that it will still work.
2021-12-05rename exe_runner to exe_wrapper everywhereEli Schwartz
I don't understand the purpose of this confusing API naming split.

2021-03-30scripts/meson_exe: fix stdout and stderr decodingAleksandr Mezin
1. use `locale.getpreferredencoding()` to get encoding name. `bytes.decode()` assumes `encoding='utf-8'` by default. It is incorrect on my Windows setup, and causes `UnicodeDecodeError`. 2. use `errors='replace'`. `bytes.decode()` assumes `errors='strict'` by default. Meson shouldn't crash if subprocess outputs some garbage that can't be decoded. `surrogateescape` doesn't work as expected on Windows. On Linux, default `errors` for `sys.stdout` is `strict`, so `surrogateescape` can't be used there too (at least until `sys.stdout` is reconfigured). Fixes https://github.com/mesonbuild/meson/issues/8480
2021-03-04mass rewrite of string formatting to use f-strings everywhereEli Schwartz
performed by running "pyupgrade --py36-plus" and committing the results
2021-03-04various python neatness cleanupsEli Schwartz
All changes were created by running "pyupgrade --py3-only --keep-percent-format" and committing the results. I have not touched string formatting for now. - use set literals - simplify .format() parameter naming - remove __future__ - remove default "r" mode for open() - use OSError rather than compatibility aliases - remove stray parentheses in function(generator) scopes
2021-02-05run_target: Add env kwargXavier Claessens
Re-implement it in backend using the same code path as for custom_target(). This for example handle setting PATH on Windows when command is an executable.
2021-01-30Fix executable as script on WindowsXavier Claessens
On Windows this would fail because of missing DLL: ``` mylib = library(...) exe = executable(..., link_with: mylib) meson.add_install_script(exe) ``` The reason is on Windows we cannot rely on rpath to find libraries from build directory, they are searched in $PATH. We already have all that mechanism in place for custom_target() using ExecutableSerialisation class, so reuse it for install/dist/postconf scripts too. This has bonus side effect to also use exe_wrapper for those scripts. Fixes: #8187

2019-08-24wine: Try to get the short paths when generating WINEPATHThibault Saunier
The size of WINEPATH is limited (1024 [until recently]), we can very easily reach that limit, and even the new one (2048) so try to keep path as small as possible by using the shortPath version of paths. Also assert that we do not reach the new hard limit. And avoid having duplicates in the list of path. [until recently]: https://bugs.winehq.org/show_bug.cgi?id=45810
2019-07-19backends: do not split command and arguments in ExecutableSerialisationPaolo Bonzini
This is not needed anymore, just make a single field with the whole command line.
2019-07-19backends: remove unnecessary fields from ExecutableSerialisationPaolo Bonzini
"exe.is_cross and exe.needs_exe_wrapper" is the same condition under which meson chooses whether to include the exe_wrapper. meson_exe has an assertion for that, but now that meson_exe does not need anymore exe.is_cross, we can simplify the code if we just "trust" meson to do the right thing. Remove both fields from ExecutableSerialisation and just test the presence of the wrapper, and also remove the executable basename which is only used to "beautify" an assertion failure.
2019-07-19backends: discover java/mono wrapper at generation timePaolo Bonzini
Move the magic to execute jar and .exe files from "meson --internal exe" to the backend, so that "ninja -v" shows more clearly what is happening. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-07-19backends: create ExecutableSerialisation in meson_exe if possiblePaolo Bonzini
If meson_exe is only being used to capture the output of the command, we can skip going through a pickled ExecutableSerialization object. This makes "ninja -v" output more useful.

2019-04-25Don't use len() to test for container emptinessDylan Baker
I ran the numbers once before (it's in the meson history) but it's *much* faster to *not* use len for testing if a container is empty or not.

2018-07-09cross: Be more permissive about not-found exe_wrapperNirbheek Chauhan
We used to immediately try to use whatever exe_wrapper was defined in the cross file, but some people generate the cross file once and use it for several projects, most of which do not even need an exe wrapper to build. Now we're a bit more resilient. We quietly fall back to using non-exe-wrapper paths for compiler checks and skip the sanity check. However, if some code needs the exe wrapper, f.ex., if you run a built executable using custom_target() or run_target(), we will error out during setup. Tests will, of course, continue to error out when you run them if the exe wrapper was not found. We don't want people's tests to silently "pass" (aka skip) because of a bad CI setup. Closes https://github.com/mesonbuild/meson/issues/3562 This commit also adds a test for the behaviour of exe_wrapper in these cases, and refactors the unit tests a bit for it.
2018-07-09cross: Use ExternalProgram for cross-file exe_wrapperNirbheek Chauhan
We already have code to fetch and find binaries specified in a cross file, so use the same code for exe_wrapper. This allows us to handle the same corner-cases that were fixed for other cross binaries.
2018-06-05Set WINEPATH when running serialized executablesNirbheek Chauhan
When the exe runner is `wine` or `wine32` or `wine64`, etc. This allows people to run tests with wine. Note that you also have to set WINEPATH to point to your custom prefix(es) if your tests use external dependencies. Closes https://github.com/mesonbuild/meson/issues/3620

2016-12-11Use universal_newlines=True for all Popen callsNirbheek Chauhan
Instead of adding it everywhere manually, create a wrapper called mesonlib.Popen_safe and use that everywhere that we call an executable and extract its output. This will also allow us to tweak it to do more/different things if needed for some locales and/or systems. Closes #1079

2016-04-18scripts/meson_exe: prepend extra_paths to PATH instead of appendingNirbheek Chauhan
This way locally-built DLLs and EXEs are preferred over system-wide ones
2016-04-15ninja: Set PATH for CustomTargets with built EXEs on WindowsNirbheek Chauhan
When a CustomTarget is run with a command that is an executable built by the project which also has a DLL built in the same project as a dependency, the EXE can't run on Windows because the DLL can't be found. On UNIX-like systems, we set the RPATH using the linker so these dependencies can be found, but on Windows the only way is to set the PATH environment variable. The same problem exists for tests, so we reuse that infrastructure by creating a new meson_exe.py script that can be used as a wrapper to run CustomTarget commands on Windows. This can later also be extended to add support for setting an environment while calling the command needed to generate a CustomTarget: https://github.com/mesonbuild/meson/issues/266
