New submission from Maxime Belanger <[email protected]>:
Uncommenting the following line in `Modules/Setup` leads to a compiler error on
macOS (tested w/ Xcode 10):
```
./Modules/expat/xmlparse.c:92:3: error: You do not have support for any sources
of high quality entropy enabled. For end user security, that is probably not
what you want.
Your options include: * Linux + glibc >=2.25 (getrandom): HAVE_GETRANDOM,
* Linux + glibc <2.25 (syscall SYS_getrandom): HAVE_SYSCALL_GETRANDOM, * BSD /
macOS >=10.7
(arc4random_buf): HAVE_ARC4RANDOM_BUF, * BSD / macOS <10.7 (arc4random):
HAVE_ARC4RANDOM, * libbsd (arc4random_buf): HAVE_ARC4RANDOM_BUF + HAVE_LIBBSD,
* libbsd
(arc4random): HAVE_ARC4RANDOM + HAVE_LIBBSD, * Linux / BSD / macOS
(/dev/urandom): XML_DEV_URANDOM * Windows (RtlGenRandom): _WIN32. If insist on
not using any of
these, bypass this error by defining XML_POOR_ENTROPY; you have been
warned. If you have reasons to patch this detection code away or need changes
to the build system,
please open a bug. Thank you!
```
I believe this is due to `setup.py` being out of sync with `Modules/Setup`,
which defines `XML_POOR_ENTROPY`. I'll attach a patch that resolves the issue
for me.
