New changeset 92f90242994652d6b7afe0a2c8a61cf2bccc8c32 by Ned Deily (Miss 
Islington (bot)) in branch '3.7':
bpo-35257: fix broken BLDSHARED - needs LDFLAGS too (GH-11297)
https://github.com/python/cpython/commit/92f90242994652d6b7afe0a2c8a61cf2bccc8c32

Since Ned pushed a new fix, I ran again my tests on the 3.7 branch with 
./configure CC=clang --with-lto --prefix /opt/py37 --enable-shared:

(1) 4 => ok
(2) 0, False => ok
(3) 0 => ok

Good! It works (in my tests).

--

"make sharedmods" runs "LDSHARED=$BLDSHARED (...) ./python setup.py build"

"make libpython(...)" uses $(BLDSHARED) to link libpython.

Modules/makesetup uses BLDSHARED to build C extensions of the stdlib. Example 
from generated Makefile:

"Modules/posix$(EXT_SUFFIX): Modules/posixmodule.o; $(BLDSHARED) 
Modules/posixmodule.o -o Modules/posix$(EXT_SUFFIX) (...)"

distutils has a customize_compiler() function which uses LDSHARED from Makefile 
(can be overriden by environment variables): it doesn't use BLDSHARED.

It seems like BLDSHARED is only used to build Python itself and stdlib modules. 
So I agree that it's ok to add PY_LDFLAGS_NODIST flags to BLDSHARED.

[issue32592] Drop support of Windows Vista in Python 3.7



STINNER Victor  added the comment:

> I failed to fix failures on my PR. It's now too late for Python 3.7.

I will try to redo PR 5231 in small chunks to better control the risk. I 
extracted os.cpu_count() changed as a new PR: PR 11457.

I already updated time.monotonic() documentation in a previous change:

commit 3ab064e80a9be1e6e9c62437fffb92bde9c5e1fb
Author: Victor Stinner 
Date:   Mon Dec 17 12:12:34 2018 +0100

bpo-23451: Update time.monotonic() documentation (GH-11190)

bpo-23451, bpo-22117: Python 3.5 requires Windows Vista or newer,
time.monotonic() is now always system-wide.

[issue35676] unittest assert helper methods have incorrect signature in docs

2019-01-07 Thread Karthikeyan Singaravelan



Karthikeyan Singaravelan  added the comment:

Thanks for the report. Looking at git history it seems there were some changes 
done in issue10573 to use (actual, expected) for consistency and later changed 
to use (first, second) in the same issue at msg126911. Discussion for the issue 
: https://mail.python.org/pipermail/python-dev/2010-December/106875.html

I think this is a bug as seen from typeshed 
https://github.com/python/typeshed/pull/2724/. But I will defer it to the 
maintainer to take a call on the same given there was a discussion in the past.

Removing versions that are on security fix only mode. I am changing the 
subject. Feel free to reword/revert.

You are right that the code doesn't crash. Just I cannot continue with the

[issue35678] subprocess.check_output(): OSError: [WinError 87]



STINNER Victor  added the comment:

"Issue with execute_child in startupinfo"

I don't think that the issue is related to startupinfo at all, since you don't 
specify this parameter in your check_output() call. Python shows you 
"startupinfo)" in the traceback because the function call takes multiple lines 
in the source code.

This issue is not a crash: it's possible to catch the exception and continue 
the execution.

[issue35671] reserved identifier violation

2019-01-07 Thread Ronald Oussoren



Ronald Oussoren  added the comment:

See: 


Basically all names starting with double underscores are reserved for the 
implementation in C++. Likewise for all names starting with an underscore when 
defining globals (such as function names).

IIRC C has similar rules for double underscores and for underscore followed by 
an uppercase letter, but I don't have a handy reference for those.

In general Python's use of these symbols should be safe enough, it is highly 
unlikely that a C/C++ implementation uses names starting with "_Py" even if 
those are reserved for the implementation.

@elfring: Do you run into actual problems due to Python's use of these 
identifiers?

[issue35678] Issue with execute_child in startupinfo



STINNER Victor  added the comment:

The screenshot says "OSError: [WinError 87] Falscher Parameter" at 
Lib/subprocess.py:1178 which is this call:

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
 # no special security
 None, None,
 int(not close_fds),
 creationflags,
 env,
 os.fspath(cwd) if cwd is not None else 
None,
 startupinfo)

According to the traceback, the call is:

subprocess.check_output([execStr,"-3",self.geofile,"-o",self.vtkFile])

Can you please dump these parameters? Are they all strings?

IMHO execStr, self.geofile or self.vtkFile is not a valid string and it's a bug 
in your code.

We frequently update OpenSSL in Python. You can get OpenSSL version using:

[issue35680] [2.7] Coverity scan: Passing freed pointer "name" as an argument to "Py_BuildValue" in _bsddb module.

2019-01-07 Thread Serhiy Storchaka



Serhiy Storchaka  added the comment:

There is no bug here. "name" is freed only when err == EINVAL. And the 
RETURN_IF_ERR() macro will return from the function if err != 0. So that a 
freed pointer will never passed to Py_BuildValue().

[issue33084] Computing median, median_high an median_low in statistics library

2019-01-07 Thread Jonathan Fine



Jonathan Fine  added the comment:

Based on a quick review of the python docs, the bug report, PEP 450
and this thread, I suggest

1. More carefully draw attention to the NaN feature, in the
documentation for existing Python versions.
2. Consider revising statistics.py so that it raises an exception,
when passed NaN data.

This implies dividing this issue into two parts: legacy and future.

For more information, see:

As for leaks in posix_putenv_garbage on Windows, it is better to open a new

[issue35679] pdb restart hooks

2019-01-07 Thread Hernot



New submission from Hernot :

I like the PDB debugger it is a quite powerfull tool, despite a few donws. One 
is that cleanup code eg registered by debugged script, module is not executed 
on restart. a crude hack is to check whether pdb is invoked via python -mpdb 
using inspect and decorate pdb._runscript and psb._runmodule methods with own 
versions calling registered cleanup methods before returning to main.

A cleaner approach would be if either pdb intercepts atexit calls recording any 
method which is registered by a call to atexit.register or provide it's own 
atexit method to register methods which pdb should call to revert to a clean 
enviroment expected by the script or module at startup.

open to any discussion, examples will follow as necessary.

This graceful reminder is most welcome. At present, it's not help I'm short of, 
but time. I've given myself a reminder, to spend time on this before the end of

Once again, thank you for this reminder. This is something I want to do. It

Your Windows cert store contains multiple invalid certificates. The first

I was clearly a bit blind.. Now with:

  +492  self.addCleanup(support.unlink, support.TESTFN)

  +497  "   time.sleep(%s)" % self.sleep_time))
  +498  start_time = time.monotonic()
  +499  proc = self.subprocess(code)
  +500  with kill_on_error(proc):
  +501  with open(support.TESTFN, 'w+b') as f:
  +502  while True:  # synchronize the subprocess
  +503  dt = time.monotonic() - start_time
  +504  if dt > 60.0:
  +505  raise Exception("failed to sync child in
%.1f sec" % dt)
  +506  try:
  +507  lock_func(f, fcntl.LOCK_EX | fcntl.LOCK_NB)
  +508  lock_func(f, fcntl.LOCK_UN)
  +509  time.sleep(0.01)
  +510  except BlockingIOError:
  +511  break

I get - PermissionError - as before.

[issue35665] Function ssl.create_default_context raises exception on Windows 10 when called with ssl.Purpose.SERVER_AUTH) attribute

2019-01-07 Thread Christian Heimes



Christian Heimes  added the comment:

OpenSSL 1.1.0 is more strict than OpenSSL 1.0.2. That's why you don't see the 
issue with Python 3.6 but with 3.7. The problem is explained in 
https://mta.openssl.org/pipermail/openssl-dev/2016-February/005100.html

The CA has encoded the integer 102 (0x66) as "02 04 00
00 00 66", which violates the DER standard. The correct encoding is "02 01  66".

>>> from asn1crypto.core import Integer
>>> import binascii
>>> binascii.hexlify(Integer(102).dump())
b'020166'

[issue35635] asyncio.create_subprocess_exec() only works in main thread

2019-01-07 Thread Stefan Seefeld



Stefan Seefeld  added the comment:

OK, so while I have been able to work around the issues (by using `quamash` to 
bridge between `asyncio` and `Qt`), I'd still like to understand the rationale 
behind the limitation that any subprocess-managing event-loop has to run in the 
main thread. Is this really an architectural limitation or a limit of the 
current implementation ?

And to your question: As I wasn't really expecting such a limitation, I would 
have expected 
"To handle signals and to execute subprocesses, the event loop must be run 
in the main thread."

to be written much more prominently (as a warning admonition even, perhaps).

Interesting commit. No idea if it's related.

commit 79790bc35fe722a49977b52647f9b5fe1deda2b7
Author: Victor Stinner 
Date:   Fri Jun 8 00:25:52 2018 +0200

bpo-33694: Fix race condition in asyncio proactor (GH-7498)

The cancellation of an overlapped WSARecv() has a race condition
which causes data loss because of the current implementation of
proactor in asyncio.

No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport
to work around the race condition.

Remove the optimized recv_into() implementation to get simple
implementation of pause_reading() using the single _pending_data
attribute.

Move _feed_data_to_bufferred_proto() to protocols.py.

Remove set_protocol() method which became useless.

[issue35635] asyncio.create_subprocess_exec() only works in main thread

2019-01-07 Thread Stefan Seefeld



Stefan Seefeld  added the comment:

> The limitation is a consequence of how Linux works.
> Unix has no cross-platform API for non-blocking waiting for child process 
> finish except handling SIGCHILD signal.

Why does the `wait()` have to be non-blocking ? We can call it once in 
response to the reception of a `SIGCHILD`, where we know the call 
wouldn't block. Then we can pass the `pid` to whatever event loop 
created the subprocess to do the cleanup there...

> On the other hand signal handlers in Python should work in the main thread.

That's fine.

> Your trick with a loop creation in the main thread and actual running in

> The behavior can be broken in next releases, sorry.

Yeah, I observed some strange issues that looked like they could be 
fixed by someone intimately familiar with `asyncio`. But given the 
documented limitation, it seemed wise not to descend into that rabbit 
hole, and so I (at least temporarily) abandoned the entire approach.

[issue35682] asyncio: bug in _ProactorBasePipeTransport._force_close()



New submission from STINNER Victor :

Running 
ProactorEventLoopTests.test_sendfile_close_peer_in_the_middle_of_receiving() 
logs a bug in _force_close(): see logs below. Extract of _force_close():

def _force_close(self, exc):
if self._empty_waiter is not None:
if exc is None:
self._empty_waiter.set_result(None)
else:
self._empty_waiter.set_exception(exc)
...

Problem: _empty_waiter can be already done. For example, it can be created 
directly as done:

def _make_empty_waiter(self):
...
self._empty_waiter = self._loop.create_future()
if self._write_fut is None:
self._empty_waiter.set_result(None)
return self._empty_waiter

Attached PR fixes _force_close(): do nothing if _empty_waiter is already done.

The regression comes from the following change:

commit a19fb3c6aaa7632410d1d9dcb395d7101d124da4

[issue35596] Fatal Python error: initfsencoding: unable to load the file system codec zipimport.ZipImportError: can't find module 'encodings'



Steve Dower  added the comment:

Looks like zipimport in 3.7 always rejected CHECKED_HASH pycs, while in 3.8 it 
always accepts them (or runs it through a validation process that passes them 
when the source file doesn't exist - I only confirmed by testing a build, not 
by walking through the new sources).

Rather than changing the old zipimport now, it's more correct to fix the 
embeddable ZIP build to specify UNCHECKED_HASH.

[issue26467] Add async magic method support to unittest.mock.Mock

2019-01-07 Thread Dima Tisnek



Dima Tisnek  added the comment:

Perhaps it's possible to vendor asynctest mock in the same vein as `mock` found 
it's way into unittest?

The real power of `asynctest` is in constructs like:

with asynctest.mock.patch("module.Class", autospec=True):
...

Where mock instances know what methods are async.

[issue35635] asyncio.create_subprocess_exec() only works in main thread

2019-01-07 Thread Andrew Svetlov



Andrew Svetlov  added the comment:

The limitation is a consequence of how Linux works.
Unix has no cross-platform API for non-blocking waiting for child process 
finish except handling SIGCHILD signal.

On the other hand signal handlers in Python should work in the main thread.

Your trick with a loop creation in the main thread and actual running in 
another thread can work, but asyncio doesn't guarantee it.
The behavior can be broken in next releases, sorry.

IIRC we discussed this scenario recently, official support for transferring a 
loop between threads is a too strict limitation, not all third-party 
implementations are ready for that.

I don’t remember the history of this.  I wonder if Brett or Eric have any 
additional insights.

[issue35596] Fatal Python error: initfsencoding: unable to load the file system codec zipimport.ZipImportError: can't find module 'encodings'



Steve Dower  added the comment:

And I assume now that the reason it broke in 3.7.2 is because the pyc mode for 
the embeddable distro changed. Which means the right place for tests is in a 
separate build that uses properly laid out Python rather than testing in the 
source tree (like what I have in the windows-appx-tests.yml file and 
Tools/msi/testrelease.bat script, but apparently also for the embeddable 
distro).

[issue32710] test_asyncio: ProactorEventLoopTests sendfile tests leak references on Windows



STINNER Victor  added the comment:

Update:

* 
test.test_asyncio.test_sendfile.ProactorEventLoopTests.test_sendfile_close_peer_in_the_middle_of_receiving
 leaks 1 reference per run: this bug is caused by bpo-35682 and fixed by PR 
11462
* 
test.test_asyncio.test_sendfile.ProactorEventLoopTests.test_sendfile_fallback_close_peer_in_the_middle_of_receiving
 leaks 1 reference per run: I don't understand why.

I spent a lot of time to investigate 
test_sendfile_fallback_close_peer_in_the_middle_of_receiving() leak and I don't 
understand the issue. The main loop is BaseEventLoop._sendfile_fallback(). For 
the specific case of this test, the loop can be simplified to:

proto = _SendfileFallbackProtocol(transp)
try:
while True:
data = b'x' * (1024 * 64)
await proto.drain()
transp.write(data)
finally:
await proto.restore()

The server closes the connection after it gets 1024 bytes. The client socket 
gets a ConnectionAbortedError exception in 
_ProactorBaseWritePipeTransport._loop_writing() which calls _fatal_error():

except OSError as exc:
self._fatal_error(exc, 'Fatal write error on pipe transport')

_fatal_error() calls _force_close() which sets _closing to True and calls 
protocol.connection_lost(). In the meanwhile, drain() raises ConnectionError 
because is_closing() is true:

async def drain(self):
if self._transport.is_closing():
raise ConnectionError("Connection closed by peer")
...

[issue35683] Enable manylinux1 builds on Pipelines



New submission from Steve Dower :

Azure Pipelines can now support container jobs: 
https://docs.microsoft.com/en-us/azure/devops/pipelines/process/container-phases?view=vsts=yaml

I experimented with enabling a manylinux1 build a while back, which should now 
be able to use identical steps to the POSIX build. With the new syntax, we can 
enable CI (and perhaps PR?) builds using the snippet below:

- job: ManyLinux1_CI_Tests
  displayName: ManyLinux1 CI Tests
  dependsOn: Prebuild
  condition: |
and(
and(
succeeded(),
eq(variables['manylinux'], 'true')
),
eq(dependencies.Prebuild.outputs['tests.run'], 'true')
)

  resources:
containers:
- container: manylinux1
  image: dockcross:manylinux-x64

  pool:
vmImage: ubuntu-16.04

  container: manylinux1

  variables:
testRunTitle: '$(build.sourceBranchName)-manylinux1'
testRunPlatform: manylinux1

  steps:

I don't have time right now to test this change, but someone else might. It's 
certainly going to be easier for someone to test it by adding this to the PR 
build first (or set up a build on your own Pipelines instance).

Maybe there are other more relevant containers we should be testing in?

[issue35681] urllib.request.HTTPPasswordMgr.add_password requires more information for HTTPPasswordMgrWithDefaultRealm

2019-01-07 Thread Tatz Sekine

New submission from Tatz Sekine :

TL;DR
HTTPPasswordMgrWithDefaultRealm.add_password() doesn't have proper
documentation.

All known version of urllib.request (or urllib2 in Python 2.x) documentaion
have the same issue.

Details:

HTTPPasswordMgrWithDefaultRealm object doesn't have its own documentation.
Instead of that, HTTPPasswordMgr's doc have information for those 2 objects:
https://docs.python.org/3.8/library/urllib.request.html?highlight=httppasswordmgr#http-password-mgr

Both objects have just 2 functions: add_password() and find_user_password().
The doc for find_user_password() has explanation how different between those 2
objects, while the one for add_password() doesn't.

One of the missing explanation for
HTTPPasswordMgrWithDefaultRealm.add_passowrd() is the value of realm. The
document has now "realm, user and passwd must be strings.", but realm could be
None for HTTPPasswordMgrWithDefaultRealm, to set default realm-less password.

That's typical use case of HTTPPasswordMgrWithDefaultRealm.add_password(), or,
that's exactly urllib howto doc mentions in

https://docs.python.org/3.8/howto/urllib2.html?highlight=httppasswordmgrwithdefaultrealm

Conclusion:

So, documentation of HTTPPasswordMgr.add_passoword() should have additional
explanation for realm which could be None for HTTPPasswordMgrWithDefaultRealm.
Or, HTTPPasswordMgrWithDefaultRealm objects could have independent section from
HTTPPasswordMgr, to clarify its usage.

Why is this matter?
Typeshed (https://github.com/python/typeshed) depends on the doc. I (or
somebody else in the company) will report it separately.
