[issue31122] SSLContext.wrap_socket() throws OSError with errno == 0

[Nikolaus Rath]

Nikolaus Rath added the comment:

Regarding "atrocious connection": I wish I knew, but I have no control of the 
connection. All I can tell is that there are frequent disconnects, occasional 
latency spikes, my remote ip address seems to change frequently (while the 
apparent local one stays as-is, so presumably some NAT in between), temporary 
bandwidth drops, etc.

[issue31061] asyncio segfault when using threadpool and "_asyncio" native module

[Alexander Mohr]

Alexander Mohr added the comment:

bad news, I just got a crash in the same place (updating defaultdict) after 
running for a week with the fixes from this and inada naoki's patches.  I think 
the threadpool may be leaking threads too as I had > 40 threads after running 
for a week when I use no more than ~10.  I'm going to switch to debug build and 
will update when I get more details.

[issue31125] shelve.open of temporary file fails with error "anydbm.error: db type could not be determined"

[Stephen Larroque]

New submission from Stephen Larroque:

This is a followup of issue 23174.

When using `shelve.open(tempfile.mkstemp()[1])`, the shelve (or anydbm or 
dumbdbm) fail with "anydbm.error: db type could not be determined".

Instead, the module could detect the file is empty and use it as if it were not 
existing before ('c' or 'n' flag). For the moment, there is no way around 
except creating the temporary file and then delete it.

[issue31100] unable to open python on Windows

[Steve Dower]

Steve Dower added the comment:

This probably means that your system failed to install the C Runtime, but not 
badly enough that it actually reported an error.

First try rebooting, and if that doesn't work then search for the VisualC++ 
2015 Redistributable installer and run that.

[issue31124] ImportError: cannot import name HAS_ALPN

[Christian Heimes]

Christian Heimes added the comment:

There is no _ssl.py. The internal _ssl module is a C extension module. Under 
Windows it is called _ssl.pyd. Do you have a _ssl.py  or _ssl package in your 
project that may confict with _ssl.pyd?

[issue31124] ImportError: cannot import name HAS_ALPN

New submission from José Leite:

When Running Web2py with Python 2.7.11 or 2.7.13 in windows 10 I get the 
following error:

Traceback (most recent call last):
File "C:\web2py\web2py.py", line 21, in

File "C:\Python27\lib\ssl.py", line 126, in 
from _ssl import HAS_SNI, HAS_ECDH, HAS_NPN, HAS_ALPN
ImportError: cannot import name HAS_ALPN


It seem like a windows Python bug in _ssl.py

[issue31114] 'make install' fails when exec_prefix is '/' and DESTDIR not empty

[Xavier de Gaye]

Xavier de Gaye added the comment:

In the subprocess test named test_executable_without_cwd and when the test is 
run on the installed Python, argv[0] is not the python executable and 
calculate_path() in Modules/getpath.c, as a last resort, searches the 
directories pointed to by the preprocessor variables PREFIX and EXEC_PREFIX 
defined in the Makefile. So this test indeed would have failed with the 
(rejected) proposition made in issue 1676135 to substitute the prefix '/' for 
'' in the configure script.  But the test would succeed when the substitution 
replaces '/' with '/./' as proposed here (after Python has effectively been 
manually installed on '/' of course).

Actually using '/.' instead of '/./' is better since the configure script will 
remove the trailing slash anyway. In both cases the value of prefix in the 
sysconfig module is '/.'.

[issue31115] Py3.6 threading/reference counting issues with `numexpr`

[Antoine Pitrou]

Antoine Pitrou added the comment:

If, judging by 
https://github.com/pydata/numexpr/commit/07d9245d88759f0c3dcabd88e6edefadc3061ee3,
 you are really calling a bunch of C API functions without holding the GIL, 
then it's not surprising you may get crashes all over the place.

[issue31113] Stack overflow with large program

Antoine Pitrou added the comment:

By the way, since you're using Python 3, you can probably workaround this issue 
by delegating some of the work to helper functions using `yield from`.
