Jules - support pyodide builds with cibuildwheel, support for graal.#4643
Merged
Conversation
We can't run child processes on Pyodide, so for testing we import pytest and call pytest.main().
We need to specify pytest in requires_dist if on pyodide, because we cannot `pip install` it ourselves because child processes are not supported. Set extra compile/link flags for pyodide, including in XCFLAGS and XCXXFLAGS, for building MuPDF.
Graal builds work by deferring to a non-graal build with graal-python's include
and library paths.
Other:
run():
Added <prefix> arg, output with prefix for each line.
Added <env> arg so caller can use a subset of os.environ.
Removed <shell> arg - we always use text command, not list of args.
Use run()'s <prefix> when running some commands.
build_extension(): allow swig=None to default to 'swig'.
git_get(): allow 'git:' string to override/specify remote/branch/tag.
PythonFlags:
Added experimental code using sysconfig.*() instead of python-config
command.
swig_get(): new, useful when wanting to use latest/specific swig.
See new arg `--graal`. Also: * support venv=3 - delete any existing venv. * support clean mupdf builds. * support custom swig command.
Also use pipcl.py's logging and run() directly.
tests/test_pixmap.py:
test_2093: exclude on graal because slow.
tests/conftest.py:
don't show or check fds on graal because lots of failures.
tests/test_tables.py:
test_2979() is slow on graal.
test_add_lines() seems to break tests/conftest.py's resetting and checking
of global state for each test. For example after test_add_lines(),
pymupdf.TOOLS.set_small_glyph_heights() always seeme to return true, so all
later tests are marked as ERROR.
