Warn when someone tries to use append() or prepend() on an env var
which already has an operation set on it. People seem to think that
multiple append/prepend operations stack, but they don't.
Closes https://github.com/mesonbuild/meson/issues/5087
we can avoid writing code like:
a = c[0]
b = c[1]
by using:
a, b = c
or
a = c[0]
b = c[1:]
by using:
a, *b = c
This saves just a bit of code and is a teeny bit faster. But mostly
for less code
Currently this is implemented as range(min(len(a), len(b)), an then
indexing into a and b to get what we actually want. Fortunately python
provides a function called zip that just does this.
* mtest: fix TAP with --verbose
TAP needs to process the test stdout even if --verbose is passed.
Capture it to a separate temporary file, and print it at the end
of the test if --verbose was passed.
In the future, we could parse it on the fly and print the result of
each TAP test point in verbose mode.
* Prefer "stderr is stdout" to "=="
The previous commit used "==" in accordance with the preexisting code,
but reviewers preferred using "is" instead. Fix both occurrences.
Instad of having special casing of threads in the backends and
everywehre else, do what we did for openmp, create a real
dependency. Then make use of the fact that dependencies can now have
sub dependencies to add threads.
I'll be using this later, but it seems useful to allow dependencies to
that have special handlers to declare that they depend on other
dependencies. This should allow us to stop treating threads special
internally and just make it a normal dependency.
Currently this only marks the pkg_config_path flag, but it could be
used to mark any of these values as having separate values for cross
and native builds, assuming that the necessary plumbing is done.
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
Since we're adding arguments that use the cross_ prefix but are valid
we don't want to print "warning invalid argument name!", as that will
confuse people by virtue of being wrong.
This returns a list out of th keys of a dict. In both cases of use
remaining though it's used for checking membership, checking for list
membership, lists are O(n) lookup, while dicts are O(1), so removing
the abstraction reduces typing and improves performance.
Currently the builtins are stored as lists, then there are a mess of
functions which take said lists, check what the type of the first
thing is, and then extract data from various points in the list based
on that.
This is stupid. This is what structs/classes are for.
If we change a symbol size (e.g. array) in a .c file that is a part of
.so, executables that use it are not re-linked resulting in a runtime
error:
"Symbol xyz has different size in shared object, consider re-linking"
Adding symbol sizes to .symbol files fixes this issue.
