Subject: package/python-engineio: drop asyncio files for python 2.x to fix pycompile issue
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b8ae383dd3a94f79530e98c1b658eaf214db9d07;p=buildroot.git

package/python-engineio: drop asyncio files for python 2.x to fix pycompile issue

engineio has conditional logic to load asyncio files when running under
Python 3.x:

if sys.version_info >= (3, 5):  # pragma: no cover
    from .asyncio_server import AsyncServer
    from .asyncio_client import AsyncClient
    from .async_drivers.asgi import ASGIApp
    try:
        from .async_drivers.tornado import get_tornado_handler
    except ImportError:
        get_tornado_handler = None
else:  # pragma: no cover
    AsyncServer = None
    AsyncClient = None
    get_tornado_handler = None
    ASGIApp = None

pycompile unfortunately errors out on these files when running under Python
2.x:

../scripts/pycompile.py ..
error:   File "/usr/lib/python2.7/site-packages/engineio/asyncio_socket.py", line 13
    async def poll(self):
            ^
SyntaxError: invalid syntax

As a workaround, simply drop the unusable file from TARGET_DIR if building
for python 2.x.
