Python 3.7 is due to be released soon: Python 3.7.0rc1, there are a number of things we can take advantage of, some may allow us to drop existing workarounds.
The most interesting features:
time.monotonic_ns- but again, the damage has been done and this will be difficult to merge with the cython code which uses cimport
Eventually, it would be nice to be able to compile with the new buffer interface and avoid deprecation warnings like #1884.
In the meantime:
OpenGL_accelerate doesn't build - see #1883.
There's a major blocker with cx_freeze, once again falling flat on its face. Looks like it does not support python 3.7 yet, and this also affects pyinstaller: zipimport.ZipImportError: can't find module 'encodings'.
$ ./Xpra_cmd.exe attach tcp:192.168.1.5:10000 Fatal Python error: init_sys_streams: can't initialize sys standard streams zipimport.ZipImportError: can't find module 'io'
Moving the missing modules by hand into the "library.zip" doesn't really help and the resulting executable still fails with:
$ ./Xpra_cmd.exe attach tcp:192.168.1.5:10000 zipimport.ZipImportError: can't find module '__startup__'
BTW, those modules were already hard-coded in setup.py to workaround existing cx_freeze breakage:
#hopefully, cx_Freeze will fix this horror: #(we shouldn't have to deal with DLL dependencies) import site lib_python = os.path.dirname(site.getsitepackages()) lib_dynload_dir = os.path.join(lib_python, "lib-dynload") add_data_files('', glob.glob("%s/zlib*dll" % lib_dynload_dir)) for x in ("io", "codecs", "abc", "_weakrefset", "encodings"): add_data_files("lib/", glob.glob("%s/%s*" % (lib_python, x)))
That's amongst a few other workarounds (base_prefix, numpy, etc)
cx_freeze can be fixed with this patch: Compilation correct .pyc files for Python 3.7.0
Created a mingw ticket for this: cx_Freeze for python3.7 needs a patch - bytecode is unusable
The MSYS2 package has been updated with the patch and we have workarounds for the rest.
One of the few noisy deprecation warnings left is from Fix collections ABCs deprecation warning).
