This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
Fixes#1470
We were adding built files to the list of source files to check for
regen. We were also not adding sources files to regen when `command:`
was used.
Fixes#1865
Using wrap mechanism in enterprise environment,
Some package is very large, example, sdk package from
BSP vendor.
so:
- open file in the output directory with a temporary name
- download a chunk, update hash calculation, write chunk to file
- when finished close file and check the hash
- if hash is incorrect, delete temp file and raise error
- if hash is correct, atomically rename temp file to final file
fix issue: #2358
fix shutil.unpack_archive() failure when the
destination files already exists and is read-only.
Example: all files in opensource package live555
is `-r--r--r--`, if some file in patch archive try to
patch original files of live555, shutil.unpack_archive
will raise `[Errno 13] Permission denied`
'mesontest' is deprecated and is now 'meson test'
Replaced all references to 'mesontest' with 'meson test' and added a note of the change in the bottom of the page
It has too many false positives. It was complaining about things like
if this:
fn = some_func
else:
fn = lambda x: ...
Where obviously, "fn" can't be a def, and it would be silly to introduce
some other name to use as the def, just to assign it to fn.
This also adds a "# noqa: F401" comment on an unused "import lzma",
which we are using it in a try/except block that is being used to
check if the lzma module is importable; of course it is unused.
v2: This turned out to be a little tricky.
mesonbuild/modules/__init__.py had the "unused" import:
from ..interpreterbase import permittedKwargs, noKwargs
However, that meant that the various modules could do things like:
from . import noKwargs # "." is "mesonbuild.modules"
Which breaks when you remove __init__.py's "unused" import. I
could have tagged that import with "# noqa: F401", but instead I
chose to have each of the module import directly from
"..interpreterbase" instead of ".".
Currently meson only considers what compiler/linker were used by a
Target's immediate sources or objects, not the sources of libraries it's
linked with by the link_with and link_while keywords. This means that if
given 3 libraries: libA which is C++, libB which is C, and libC which is
also C, and libC links with libB which links with libA then linking libC
will be attempted with the C linker, and will fail.
This patch corrects that by adding the compilers used by sub libraries
to the collection of compilers considered by meson when picking a
linker.
This adds a new process_compilers_late method to the BuildTarget class,
which is evaluated after process_kwargs is called. This is needed
because some D options need to be evaluated after compilers are
selected, while for C-like languages we need to check the link* targets
for language requirements, and link* targets are passed by kwargs.
This implementation is recursive, since each Target adds it's parent's
dependencies.
This method accepts a single function that takes no arguments and
returns a single value which can be a value that can be cast to
a 64-bit signed integer, or a string, and returns that value.
Mostly useful for running foolib_version() functions that return the
currently-available version of libraries.
