[issue20981] ssl doesn't build anymore with OpenSSL 0.9.7 or older: X509_check_ca

[Mișu Moldovan]

Mișu Moldovan added the comment:

Starting with 2.7.9, this affects the 2.7 branch as well.

Please note that it's not only out-of-maintenance FreeBSD versions that are 
affected, but also a current version of Solaris, namely Solaris 10. The end of 
"Premier" support for Solaris 10 is January 2018 and the end of "Extended" 
support for Solaris 10 is January 2021, according to 
http://www.oracle.com/us/support/library/lifetime-support-hardware-301321.pdf

Solaris 10 has OpenSSL 0.9.7 and all security fixes are back-ported to it, more 
at https://blogs.oracle.com/darren/entry/openssl_versions_in_solaris

0.9.7 is truly ancient. I'd rather not add more conditional code and let people

[issue23143] Remove some conditional code in _ssl.c

[Antoine Pitrou]

New submission from Antoine Pitrou:

There's a lot of conditional code in _ssl.c, meant to address the 
unavailability of some features in old OpenSSL versions. I think for 3.5 we 
should require at least 0.9.8 (which is already old), and consequently remove 
some of those conditionals.

[issue23140] InvalidStateError on asyncio subprocess task cancelled

[Xavier de Gaye]

Xavier de Gaye added the comment:

The exception is not raised when loop.set_debug(False) on my linux box.
So I guess this may be not reproductible on all platforms.
The new attached test_cancel_2.py raises an exception while asyncio debug is 
false, by forcing one more iteration of the loop after the pending tasks list 
is empty.

Also with asyncio debug false and with test_cancel_2.py and after removing the 
last task from the initial tasks list (i.e. asyncio.Task(asyncio.sleep(10))):
  * with more_iterations = 2:  the exception is raised, not often
  * with more_iterations = 3:  the exception is raised, seemingly always
  * with more_iterations = 0:  another exception, often;
  Exception ignored when trying to write to the signal wakeup fd:
  OSError: [Errno 9] Bad file descriptor

[R. David Murray]

R. David Murray added the comment:

According to the docs, there's no reason to use FunctionTestCase unless you are 
dealing with legacy test code (eg: importing it from some existing module), so 
yes your "this seems easier" is certainly easier :)

(I wasn't even aware FunctionTestCase existed.)

I'm not sure what the issues would be with making them discoverable.  We'll wee

[issue23076] list(pathlib.Path().glob("")) fails with IndexError

[liu chang]

liu chang added the comment:

hi pitrou, should we fix it in _make_selector(pattern_parts) function? 
origin code as:

def _make_selector(pattern_parts):
pat = pattern_parts[0]
child_parts = pattern_parts[1:]
if pat == '**':
cls = _RecursiveWildcardSelector
elif '**' in pat:
raise ValueError("Invalid pattern: '**' can only be an entire path 
component")
elif _is_wildcard_pattern(pat):
cls = _WildcardSelector
else:
cls = _PreciseSelector
return cls(pat, child_parts)

Is it a good fix that: check the length of pattern_parts, if its length < 2, we 
set pat to empty str, set child_parts to a empty list。

A simple code like:

def _make_selector(pattern_parts):
try:
pat = pattern_parts[0]
child_parts = pattern_parts[1:]
except IndexError:
pat = ""
child_parts = []
if pat == '**':
cls = _RecursiveWildcardSelector
elif '**' in pat:
raise ValueError("Invalid pattern: '**' can only be an entire path 
component")
elif _is_wildcard_pattern(pat):
cls = _WildcardSelector
else:
cls = _PreciseSelector
return cls(pat, child_parts)

[issue23145] regrtest: log test loader errors

[STINNER Victor]

New submission from STINNER Victor:

Currently, when regrtest fails to load a test submodule, no exception is 
raised, no error is logged.

I propose to at least log all loader errors: see attached regrtest.patch.

For an example, try to apply the attached test_asyncio_bug.patch and run:
./python -m test -m test_not_implemented test_asyncio

The current output is:
---
[1/1] test_asyncio
1 test OK.
---

The output with regrtest.patch:
---
haypo@selma$ ./python -m test -m test_not_implemented test_asyncio
[1/1] test_asyncio
Failed to import test module: test.test_asyncio.test_base_events

[issue22560] Add loop-agnostic SSL implementation to asyncio

[STINNER Victor]

STINNER Victor added the comment:

Sorry for the delay. I understood that the change targets the proactor event 
loop, and I was busy to fix annoying random bugs in this code (it's not done 
yet, see for example the issue #23095 for the most recent bug). Windows is not 
my favorite OS, I am less intersted to fix Windows specific bugs, but sometimes 
I try to fix them.

I still don't understand if the change is (or should be) specific to the 
proactor event loop or not. Antoine, can you please elaborate the rationale of 
your patch?

Is the "legacy" code only used on Python 3.4 and older? Is ssl.MemoryBIO always 
present in Python 3.5 and newer?

I would like to see benchmarks of memory BIO vs current code on Linux and 
Windows. Even if it would make the code simpler to always use memory BIO, I 
care of network performances. Maybe we may only use memory BIO for the proactor 
event loop?

Do you know if other applications use memory BIO for networking with SSL?

Did you try your patch on Python 3.3? On Linux and Windows?

Anyway, great job!

FYI Twisted supports SSL with IOCP using pyOpenSSL 0.10 (released in 2009) or 
newer. The support is based on twisted.protocols.tls.TLSMemoryBIOFactory.

It looks like the memory BIO implementation is now preferred on all platforms. 
See the twisted.internet._newtls module:
"""
This module implements memory BIO based TLS support.  It is the preferred
implementation and will be used whenever pyOpenSSL 0.10 or newer is installed
(whenever L{twisted.protocols.tls} is importable).

[issue22560] Add loop-agnostic SSL implementation to asyncio

[Guido van Rossum]

Guido van Rossum added the comment:

Oh, I think I understand how this could help STARTTLS. Glyph once explained it 
to me. STARTTLS takes an existing non-TLS Transport and layers a TLS Transport 
on top of it. This requires the TLS layer to read/write from the underlying 
Transport using the standard Transport/Protocol interface (i.e. call 
transport.write() to write bytes, expect protocol.data_received() to be called 
when bytes are read). The existing (3.4) ssl module cannot do this because the 
TLS implementation needs to wrap the socket directly; but (presumably) the 
BIO-based TLS implementation can do this.
