test_asyncio

git bisect blames ba7e1f9a4e06c0b4ad594fd64edcaf7292515820. Looking at the 
patch it looks to me the problem is in test_get_event_loop_new_process(), the 
pool is not shutdown.

[issue30030] Simplify _RandomNameSequence

2017-04-19 Thread Serhiy Storchaka


Serhiy Storchaka added the comment:

On Linux creating a temporary file or directory usually consumes only one 
random name. But due to a bug on Windows (issue22107) it can consume up to 
TMP_MAX (2147483647 on Windows) names when called with read-only directory. 
Generating every name consumes about 16 random bytes. This can exhaust the 
system entropy and slowdown other applications.

Serhiy Storchaka added the comment:

I don't know whether the fix for 2.7 is needed. The interface of tokenize is 
different in 2.7. Just run the new test and see if it fails.

[issue24739] allow argparse.FileType to accept newline argument

2017-04-19 Thread Berker Peksag


Berker Peksag added the comment:

I agree with paul j3. It would be nice to keep the current FileType API as is. 
The argparse documentation already encourages people to write their own custom 
types and I think this is a good use case for following the advice.

Thanks for the report!

[issue30102] improve performance of libSSL usage on hashing

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

> This small change also changes behavior of OpenSSL dramatically.

What do you mean by "dramatically"? What does a openssl.cnf configuration 
contain?

Do other applications using OpenSSL call OPENSSL_config(NULL)?

Since OPENSSL_config() accepts a filename, maybe a first step would be to 
expose the function as ssl.OPENSSL_config(filename) to allow user to load 
*explicitly* a configuration file? ssl.OPENSSL_config() would call 
OPENSSL_config(NULL). Would it work for you, Gustavo?

[issue30024] Treat `import a.b.c as m` as `m = sys.modules['a.b.c']`

2017-04-19 Thread Pavol Lisy


Pavol Lisy added the comment:

Maybe I am wrong but don't we get another weird behavior? 

   import sys.path  # this is error now
   ModuleNotFoundError: No module named 'sys.path'; 'sys' is not a package

So we probably expect same behavior here:

   import sys.path as foo

But if we just replace LOAD_ATTR with IMPORT_FROM in the compiler then wouldn't 
it works like:

   from sys import path as foo

?

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

> The test should try to write the file in a temporary file, or simply skip the

I proposed https://github.com/python/cpython/pull/1196 to skip the test in that 
case.

Creating a temporary file is more complex since the API doesn't work as a 
context manager, and it's unclear who would be responsible to remove the 
temporary file.

[issue30106] test_asyncore: test_handle_write() fails in tearDown()

2017-04-19 Thread STINNER Victor


New submission from STINNER Victor:

On the AMD64 FreeBSD CURRENT Non-Debug 3.x buildbot, test_handle_write() of 
test_asyncore now fails on calling asyncore.close_all() in tearDown().

Moreover, since my commit 7b9619ae249ed637924d1c76687b411061753e5a, the 
following test_quick_connect() now fails on self.fail("join() timed out"). I 
guess that asyncore.socket_map still contains unwanted sockets from 
test_handle_write() which failed.

Attached PR should fix the test_handle_write() failure by calling 
asyncore.close_all() with ignore_all=True.

[issue30105] Duplicated connection_made() call for some SSL connections

2017-04-19 Thread kyuupichan


New submission from kyuupichan:

An asyncio SSL server frequently sees duplicated connection_made() calls for an 
incoming SSL connection.  It does not happen to all SSL connections; perhaps 
10-25% of them.  It never happens to TCP connections. 

Here are some examples of logs from one I run.  I see this on MacOSX and 
DragonflyBSD, others have reported the same on Linux, so I believe it's a quirk 
in asyncio and not O/S specific.  I assume it is a bug in the wrapping of the 
raw TCP transport with an SSL one.

2017-04-20 07:22:44.676180500 INFO:ElectrumX:[14755] SSL 218.185.137.81:52844,

256 total

The log is output on a connection_made() callback to a protocol, and not from 
the protocol's constructor.  They are very close together, from the same IP 
address and ports that are close together.  The first connection was closed 
with connection_lost() before the 2nd connection_made() because the total 
session count (here 256) did not increase.

Here is another section of my log with 2 more examples.  Totals are not 
monotonic because of course disconnections (not logged) happen all the time.

Another reason I believe this is an asyncio issue on the server side is that 
someone else's server software that doesn't use asyncio logs in a similar way 
and does not see duplicated incoming "connections".

[issue30100] WeakSet should all discard and remove on items that can have weak references

2017-04-19 Thread donkopotamus


donkopotamus added the comment:

Just to add, I framed this slightly wrongly by using a list [] as an example, 
whereas my original motivating case was objects that are hashable but not 
weakly referenceable.   (eg () ).

So there are two cases to consider ... what to do in discard/remove etc when 
the value is (i) not weakly referenceable, and (ii) when the value is not 
hashable.

Serhiy Storchaka added the comment:

test_threadedtempfile passed on Linux, but randomly failed on Windows. :( And 
_RandomNameSequence is used not only in tempfile.

I suggest to wait until add a wrapper that makes generators thread-safe. Since 
it added we could restore the generator implementation of _RandomNameSequence.

[issue30030] Simplify _RandomNameSequence

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

> Remoe _get_candidate_names() and the global _name_sequence

I understood the rationale behind _get_candidate_names() is to prevent 
generating the same name when _RandomNameSequence() uses random.Random. Since 
my change uses random.SystemRandom, I consider that it's now ok to create 
multiple generators in paralle. Is that rationale correct?

[issue30030] Simplify _RandomNameSequence

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

I reopen the issue to propose a different approach: 
https://github.com/python/cpython/pull/1191 replaces Random with SystemRandom 
and drops get_candidate_names().

@Serhiy: I hesitated to add you as a co-author, but I'm not sure that you like 
my approach :-) Tell me what do you think. At least, I reused your docstring 
and your updated unit test!

[issue28533] Replace asyncore

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

asyncore was modified to emit a DeprecationWarning:
http://bugs.python.org/issue25002#msg279417

But then a lot of code starts with to fail -Werror.

Copy of Martin Panter's msg279469:

I normally run the tests with -Werror, and the failures I get are:

* test_ssl, test_smtplib, test_poplib, test_logging, test_ftplib, test_support: 
tests use asyncore
* test_os: test uses asynchat (When you import asynchat, the first error 
complains about importing asyncore, there are actually two warnings)
* test_all: This seems to ignore DeprecationWarning; perhaps an exception for 
PendingDeprecationWarning should also be added?
* test_asyncore and test_asynchat: Obviously these have to still test the 
modules, so they should anticipate the warnings, perhaps using Serhiy’s code
* test_smtpd: smtpd module itself uses asyncore; see Issue 25008

[issue28533] Replace asyncore

2017-04-19 Thread STINNER Victor


STINNER Victor added the comment:

> asyncore is still used in several tests and should be replaced.

Here is the list of Python files using asyncore:

haypo@selma$ grep -l asyncore $(find -name "*.py")
./Lib/asyncore.py
./Lib/asynchat.py
./Lib/test/test_smtpd.py
./Lib/test/test_asyncore.py
./Lib/test/test_smtplib.py
./Lib/test/test_os.py
./Lib/test/test_ssl.py
./Lib/test/test_logging.py
./Lib/test/libregrtest/save_env.py
./Lib/test/test_asynchat.py
./Lib/test/test_pyclbr.py
./Lib/test/test_support.py
./Lib/test/test_poplib.py
./Lib/test/test_ftplib.py
./Lib/smtpd.py

smtpd has been rewritten with asyncio:
http://aiosmtpd.readthedocs.io/

The documentation of the smtpd module already points to aiosmtpd.

libregrtest/save_env.py only checks that asyncore.socket_map is not modified, 
we can keep it until asyncore is really removed.

test_support.py only tests that it's possible to have a "clean" import of 
asyncore, it can be easily be replaced later.

The list can reduced to:

./Lib/test/test_smtplib.py
./Lib/test/test_os.py
./Lib/test/test_ssl.py
./Lib/test/test_logging.py
./Lib/test/test_pyclbr.py
./Lib/test/test_poplib.py
./Lib/test/test_ftplib.py

[issue30104] Float rounding errors on AMD64 FreeBSD CURRENT Debug 3.x buildbot

2017-04-19 Thread STINNER Victor


New submission from STINNER Victor:

Since the build 154, many tests fail on the AMD64 FreeBSD CURRENT Debug 3.x 
buildbot slave because of float rounding errors. Failing tests:

* test_cmath
* test_float
* test_json
* test_marshal
* test_math
* test_statistics
* test_strtod

http://buildbot.python.org/all/builders/AMD64%20FreeBSD%20CURRENT%20Non-Debug%203.x/builds/154/steps/test/logs/stdio

Problem: none of build 154 changes are related to floats

* commit f9f87f0934ca570293ba7194bed3448a7f9bf39c
* commit 947629916a5ecb1f6f6792e9b9234e084c5bf274

It looks more like a libc change of the FreeBSD CURRENT slave.

Example of errors:

In case you didn't get notified by Rietveld, I made a couple suggestions on 
your latest patch. Also, if you wouldn't mind, please update the patch to apply 
cleanly to 3.7 -- especially since STARTUPINFO now has an __init__ method.

[issue30102] improve performance of libSSL usage on hashing

2017-04-19 Thread Gustavo Serra Scalet


Gustavo Serra Scalet added the comment:

> Christian Heimes added the comment:
> 
> This small change also changes behavior of OpenSSL dramatically. What
> are your Python and OpenSSL versions? 

I tested by compiling my own python3 (8aaf499) against its parent (d6d344d) For 
python2, I made the same by compiling the 2.7.13 as a baseline and results were 
consistent with the python I have on Ubuntu 17.10 (3.5.3 and 2.7.13).

> How did you profile the
> performance of the hashing functions?

I compared the timings between my patched vs patchless python versions by using 
a 630MB file to calculate sha256 as:

perf stat -r 10 Python-2.7.13/python -c "import hashlib; 
print(hashlib.sha256(open('ubuntu-16.10-server-ppc64el.iso','rb').read()).hexdigest())"

The speedup of ~50% is given due to patchless taking 3.082156387s and patched 
taking 2.027484800s (errors are less than 1%)

I also noticed what changed on a code level by checking with gdb what is being 
executed on the sha loop. After my patch I see altivec (SIMD) functions being 
used on SHA main loop.

> If OpenSSL_config() really improves performance on relevant platforms,
> then we should be consistent and call it in _ssl.c, too.

I'll check that then. Thanks for the hint.

Ps: please note this behavior is noticed on a POWER8 machine. I'm not an 
OpenSSL expert so I don't know if there are now more optimizations enabled on 
other architectures as well.

This small change also changes behavior of OpenSSL dramatically. What are your 
Python and OpenSSL versions? How did you profile the performance of the hashing 
functions?

If OpenSSL_config() really improves performance on relevant platforms, then we 
should be consistent and call it in _ssl.c, too.

[issue30103] uu package uses old encoding

2017-04-19 Thread Kyle Glowacki


New submission from Kyle Glowacki:

Looking in the man pages for the uuencode and uudecode 
(http://www.manpagez.com/man/5/uuencode/), I see that the encoding used to go 
from ascii 32 to 95 but that 32 is deprecated and generally newer releases go 
from 33-96 (with 96 being used in place of 32).   This replaces the " " in the 
encoding with "`".  

For example, the newest version of busybox only accepts the new encoding.

The uu package has no way to specify to use this new encoding making it a pain 
to integrate.   Oddly, the uu.decode function does properly decode files 
encoded using "`", but encode is unable to create them.

[issue30102] improve performance of libSSL usage on hashing

2017-04-19 Thread Gustavo Serra Scalet


New submission from Gustavo Serra Scalet:

To correctly pick the best algorithm for the current architecture,
libssl needs to have OPENSSL_config(NULL) called as described on:
https://wiki.openssl.org/index.php/Libcrypto_API

This short change lead to a speedup of 50% on POWER8 when using
hashlib.sha256 digest functionality as it now uses a SIMD approach that was 
already existing but not used by cpython.
