on win32 clean install:
Traceback (most recent call last): File "E:\Xpra\trunk\src\dist/lib/xpra/net/compression.py", line 24, in <module> import lz4 File "C:/msys64/mingw64/lib/python2.7/site-packages/lz4-2.1.0-py2.7-mingw.egg/lz4/__init__.py", line 8, in <module> VERSION = __version__ NameError: name '__version__' is not defined
So, it turns out (unsurprisingly) that python-lz4 has changed how it gets its version information yet again - I can't remember if it's 3rd or 4th time now. And when it doesn't get its version number, the whole library fails to load!
For such a small and simple wrapper library, the number of releases and constant needless breakage is shocking.
Here's what it does now:
from pkg_resources import get_distribution, DistributionNotFound try: __version__ = get_distribution(__name__).version except DistributionNotFound: # package is not installed pass
And here's what I replaced it with to get on with more productive things:
# package is not installed __version__ = "2.1.0"
Let's try to deal with this in #1883 so this won't break again next time there is an update.
r20171 fixes the packaging for macos by adding the patch to jhbuild.
The import problem has been resolved, there were other reasons for avoiding pkg_resources: Importing lz4 is very slow
We now use version 2.1.2: r20928.
