* mesonlib: handle meson exe wrappersMartin Kelly2018-05-301-0/+8
| | | | | | | | | | | | | | | | | | | | There are cases when it is useful to wrap the main meson executable with a script that sets up environment variables, passes --cross-file, etc. For example, in a Yocto SDK, we need to point to the right meson.cross so that everything "just works", and we need to alter CC, CXX, etc. In such cases, it can happen that the "meson" found in the path is actually a wrapper script that invokes the real meson, which may be in another location (e.g. "meson.real" or similar). Currently, in such a situation, meson gets confused because it tries to invoke itself using the "meson" executable (which points to the wrapper script) instead of the actual meson (which may be called "meson.real" or similar). In fact, the wrapper script is not necessarily even Python, so the whole thing fails. Fix this by using Python imports to directly find mesonmain.py instead of trying to detect it heuristically. In addition to fixing the wrapper issue, this should make the detection logic much more robust.

* Move builtin_argument_registration to coredataDylan Baker2018-04-171-21/+1
| | | | | | We're going to want to use these functions in meson configure as well to make the command line options the same between `meson` and `meson configure`.
* Accept builtin options with -D when making initial meson callDylan Baker2018-04-171-0/+20
| | | | | | | | | | | | | | | | | | | | Currently meson only accepts `-Dopt=value` for builtin options when calling `meson configure` and `--opt=value` for builtin options when calling `meson` initially. This is a confusing behavior, and users only get a small warning at the top of a potentially long configuration summary to catch this. This has confused end users and developers alike, there are at least 5 duplicates of the bug this fixes, and I have personally been asked about this more times than I can count. The help documentation doesn't make it clear that -D cannot be used to set options like prefix and bindir. This adds support for -D options to the initial meson call, but not -- options to the meson configure call. I think it's better to have one way to do things, and -- options are kinda one off while -D is used everywhere else, so lets stick with that. Related #969
* mesonmain: be DRYDylan Baker2018-04-171-24/+4
| | | | | | We have all the information needed to calculate the builtin arguments in the coredata module already, don't duplicate that in the mesonmain module as well.
* coredata: encapsulate destination nameDylan Baker2018-04-171-2/+2
| | | | | This means that there are no special args passed ot builtin args anymore.
* coredata: Add helper for setting actionDylan Baker2018-04-171-5/+7
| | | | | | | Currently we manually pass the argparse action, this isn't very DRY, since the builtin_types already has all the data necessary to find that. This adds a new function to determine the action based on the default type.

* Verify that failing tests are failing with an error, not a python exceptionJon Turney2018-02-151-1/+2
| | | | | | | | | | | | | | | PR #2527 suggests "making failing tests more strict about failing gracefully". To achive this, make meson exit with distinct exit statuses for meson errors and python exceptions, and check the exit status is as expected for failing tests. I can't see how to write a test for this, within the current framework. You can test this change by reverting the fix (but not the test) from commit 1a159db8 and verifying that 'test cases/failing/66 string as link target' fails.
* Ensure any generation error appears in the logfile and thus in CI outputJon Turney2018-02-141-4/+5
| | | | | | | | | | | | | | | Since c2a5ac39, MesonApp.generate() closes the logfile before returning, which means that when invoked by mesonmain.run(), any MesonException is not logged there. MesonApp.generate() does not appear to have any other users I can find. This somewhat reduces the diagnostic value of the logfile. This also interacts badly with running project tests in CI, as _run_tests chooses to report the logfile contents, rather than stdout, for the configure step, and it thus doesn't report any configure error which caused a test failure.

These are already matched by the default compilation-error-regexp-alist in emacs. Also: Don't start 'red' markup until after the \n before an error Unabsorb full-stop at end of warning with location from mlog.warning() Update warning_location test

| * Make sysconfdir, localstatedir and sharedstatedir defaults depend on prefixJon Turney2017-10-281-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | Rather than requiring a bit of boilerplate in every meson.build, which is only documented in a comment in mesoncore.py, use sensible defaults for sysconfdir, localstatedir and sharedstatedir depending on the prefix. Fixes #1637 v2: For clarity, give get_builtin_option_default() a noneIfSuppress argument, rather than overloading prefix '' and None with special meanings.

|/ | | | | | | | | Unfortunately, `time.time` and file timestamps are not guaranteed to be in sync and due to various kernel caches may be different enough to cause rebuilds to fail [1].
