* docs: document unrecognized escape sequence behaviour [skip ci]
Document that unrecognized escape sequence behaviour is like python, not
C.
* Don't try to decode invalid hex escape sequences
Don't try to decode escape sequences which should contain a sequence of
hex digits, but don't, throwing a python exception. These will treated
literally instead.
* Extend test case to cover invalid escape sequences

Ninja backend refactoring
|
|
Previously, this called out to the %ninja_test macro to run the
tests, but that limits us to only the arguments that ninja can
understand. In particular, it is not possible to add a test
timeout multiplier (such as is sometimes needed when building for
slow architectures such as armv7hl). With this patch, it will be
possible to specify `%meson_test -t 5` in the RPM spec file
without needing to patch the sources to extend the timeouts,
making life easier for packagers.

Don't bother outputting any rules which aren't referenced by any build
statement.
|

|
|
Pass the command line to NinjaRule() as a list of strings, not already
concatenated as a string.

After the previous commit, outfile is now passed down to lots of things
which don't use it, as they only create built statements, rather than
writing them out. Remove these unnecessary args.
|
|
Store the build statements and then write them all out, rather than
writing them out as we go.
Construct a NinjaBuildElement for the 'PHONY' target, rather than
writing it literally to the build.ninja file.

Store the rule broken down into parts which do and don't go into
rspfile, so we can construct either a rsp or non-rsp version of the
rule.

due to refactoring this is now useless.
|
|
Instead of using the ___cmp__ method just straight up compare the two
values, since we've already converted numbers to ints and split
non-numeric seperators this is sufficient, and 4x faster
|
|
makes version comparisons even faster
|
|
Instead of range. This makes version comparison 25-50% faster depending
on the operator and how different the values are.
|
|
Before this we only covered >, <, and ==, but we an apply some basic
logic to know that a > b == !(a <= b), or that if a > b then a != b.
This uncovered some bugs I wrote while working on this code.
|
|
We really should be testing using the operators themselves, not the
internal implementations, ie we should use a > b not a.__cmp__(b) == 1
in our tests, because __cmp__ is just an implementation detail.
|
|
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.
|
|
This uses an iterator instead of walking a list, which is roughly twice
as fast. This also does away with the pre-check on whether the list is
valid for converting to a dict, and instead handles the case of an
uneven number by catching another exception. This is preferable since
it's a fatal error anyway, so avoiding it in the non-fatal case is
preferable.
|
|
The ternary returns True or False from an expression that returns True
or False: i.e. True if bool(value) else False.
|
|
The cl.exe from Visual Studio 2010 and earlier report '80x86', not
'x86', for the architecture that the compiler supports. So, we ought
to check for that as well to see whether we are building for 32-bit x86.

Gcovr 4.2
|
|
ast: Add basic string operation support for AstInterpreter (fixes #5286)
|
|
|
|
|
|
|
|
The out-of-source build syntax for gcovr 4.2 is different compared to
previous versions and therefore an update was needed. In researching the
most appropriate solution it was found that any gcovr version older than
3.3 always resulted in 0% coverage. Because of this, rather than adding
an additional layer of logic, some already existing logic was modified
to ensure correct syntax for the new version, while versions older than
3.3 are flagged as not supported.
Closes mesonbuild#5089.

Setting this variable to contain additional commands to symlink shlib
aliases was removed in commit c0bf3e8d, so it's always unset now, and
thus does nothing.

This isn't safe given the way python implements default arguments.
Basically python store a reference to the instance it was passed, and
then if that argument is not provided it uses the default. That means
that two calls to the same function get the same instance, if one of
them mutates that instance every subsequent call that gets the default
will receive the mutated instance. The idiom to this in python is to use
None and replace the None,
def in(value: str, container: Optional[List[str]]) -> boolean:
return src in (container or [])
if there is no chance of mutation it's less code to use or and take
advantage of None being falsy. If you may want to mutate the value
passed in you need a ternary (this example is stupid):
def add(value: str, container: Optional[List[str]]) -> None:
container = container if container is not None else []
container.append(value)
I've used or everywhere I'm sure that the value will not be mutated by
the function and erred toward caution by using ternaries for the rest.

With dependencies specifed, mode='compile' causes it to ignore the link
arguments and thereby always fails.
