[issue18906] Create a way to always run tests in subprocesses within regrtest

[STINNER Victor]

STINNER Victor  added the comment:

Since 2013, the Python test suite evolved a lot. First, we fixed hundreds of 
bugs where tests leaked various kinds of resources: processes, threads, file 
descriptors, memory, etc. Second, python3 -m test -j0 now runs each test file 
in a subprocess. Maybe we should emit a warning when tests are run 
sequentially, without -j0. Maybe it should be an opt-in option, rather than the 
default. But I prefer to close this old issue. Please open a new issue if you 
want to make further changes in regrtest.

I'm not brave enough yet to make such large changes into Python 2.7 build

[issue37400] test_os: test_chown() started to fail on AMD64 FreeBSD 10-STABLE Non-Debug 3.* buildbots

[STINNER Victor]

New submission from STINNER Victor :

https://buildbot.python.org/all/#/builders/167/builds/1265

test_chown (test.test_os.ChownFileTests) ... ERROR

==
ERROR: test_chown (test.test_os.ChownFileTests)
--
Traceback (most recent call last):
  File 
"/usr/home/buildbot/python/3.x.koobs-freebsd10.nondebug/build/Lib/test/test_os.py",
 line 1327, in test_chown
os.chown(support.TESTFN, uid, gid_1)
PermissionError: [Errno 1] Operation not permitted: '@test_95158_tmp'

Extract of the test:

import grp
groups = [g.gr_gid for g in grp.getgrall() if getpass.getuser() in g.gr_mem]
if hasattr(os, 'getgid'):
process_gid = os.getgid()
if process_gid not in groups:
groups.append(process_gid)

@unittest.skipUnless(len(groups) > 1, "test needs more than one group")
def test_chown(self):
gid_1, gid_2 = groups[:2]
uid = os.stat(support.TESTFN).st_uid
os.chown(support.TESTFN, uid, gid_1)  # < FAIL HERE
gid = os.stat(support.TESTFN).st_gid
self.assertEqual(gid, gid_1)
os.chown(support.TESTFN, uid, gid_2)
gid = os.stat(support.TESTFN).st_gid
self.assertEqual(gid, gid_2)

Extract of test.pythoninfo:

os.uid: 1002
os.umask: 077
os.gid: 1002
os.groups: 1002


I'm not sure that the code to manually get groups from grp.getgrall() is 
correct. Why not relying on the *current* groups, os.getgroups()?

Note: there is also os.getgrouplist(), I'm not sure of the difference between 
os.getgroups() and os.getgrouplist(). I know that os.getgrouplist() was 
modified recently to use:

/*
 * NGROUPS_MAX is defined by POSIX.1 as the maximum
 * number of supplimental groups a users can belong to.
 * We have to increment it by one because
 * getgrouplist() returns both the supplemental groups
 * and the primary group, i.e. all of the groups the
 * user belongs to.
 */
ngroups = 1 + MAX_GROUPS;

[issue37398] contextlib.ContextDecorator decorating async functions

[John Belmonte]

John Belmonte  added the comment:

I have a context manager used for timing sections of code or whole functions 
(when used as a decorator).  It's aware of the Trio async/await scheduler and 
is able to exclude periods of time where the task is not executing.  The 
context manager itself is not async.

Synopsis of decorator case:

  @PerfTimer('query')
  async def query_or_throw(self, q):
  return _parse_result(await self._send_query(q))

I'd like to just use the existing ContextDecorator to define the PerfTimer 
context manager, and have it wrap coroutine functions properly.  New API is not 
required.

[issue37400] test_os: test_chown() started to fail on AMD64 FreeBSD 10-STABLE Non-Debug 3.* buildbots

[Kubilay Kocak]

Kubilay Kocak  added the comment:

And I just remembered that I had to restart the build worker service on that 
host (koobs-freebsd10) this morning as I was receiving messaging that the 
worker had gone missing.

I ran `[koobs@10-STABLE-amd64:~] sudo /usr/local/etc/rc.d/buildslave restart`

which is the same as the prevailing reproduction case in #27838

I could restart the worker to make the issue go away, but I think the 
underlying issue should be fixed instead.

Should we close this as a dupe and reopen the original?

[issue37398] contextlib.ContextDecorator decorating async functions

[John Belmonte]

John Belmonte  added the comment:

PerfTimer is a reusable, non-reentrant context manager implemented as a class.

There are already use cases of ContextDecorator described in the contextlib 
documentation, such as the track_entry_and_exit logger.  What reason would you 
have for such context managers to *not* wrap async functions properly?

[issue37398] contextlib.ContextDecorator decorating async functions

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Got you.

iscoroutinefunction() is not reliable: it detects async functions only but 
fails if we have a regular function that returns awaitable object.

I think AsyncContextDecorator is needed here to explicitly point that you want 
to wrap async function.

Another question is: sync or async context manager should be applied? I see use 
cases for both variants

[issue34606] Unable to read zip file with extra

[Andreas Gäer]

Andreas Gäer  added the comment:

I'm a little bit puzzled that this bug is closed as "not a bug" despite the 
fact that all versions of python allow the user to create "invalid" ZIP files 
and all version up to 3.7 are able to read those "invalid" files.

Currently we're stuck with a lot of already created ZIP files that cannot be 
read or fixed after an update to 3.7.

Would it be an option to make decoding of extra data optional eg. with an extra 
keyword arg to __init__?

[issue37398] contextlib.ContextDecorator decorating async functions

[John Belmonte]

John Belmonte  added the comment:

My use case is for a non-async context manager, and if we take 
track_entry_and_exit as an example that's non-async as well.

The explicit approach (e.g. separate base class for decorators applied to sync 
vs. async functions) doesn't seem ideal, because it precludes having a single 
context manager for both cases.  track_entry_and_exit is an example where a 
context manager would want to decorate both types of functions.

I'm not sure how big of a problem the iscoroutinefunction() limitation is-- in 
Trio style we don't pass around coroutines by normal functions.  The `async` 
qualifier exists to make it clear when a function returns a coroutine, and 
ContextDecorator already doesn't work for the case of a regular function 
returning a coroutine.  I think the scope here is to enhance ContextDecorator 
to work with async functions which are properly qualified with `async`.

[issue37402] Fatal Python error: Cannot recover from stack overflow issues on Python 3.6 and 3.7

[Andreas Jung]

New submission from Andreas Jung :

I am using Python 3.6 and 3.7 (always latest minor releases) with Plone 5.2 and 
I various issues with 

Fatal Python error: Cannot recover from stack overflow.

and do not make much sense to me.

Some related tracebacks are documented here

https://github.com/plone/Products.CMFPlone/issues/2874

https://community.plone.org/t/fatal-python-error-cannot-recover-from-stack-overflow/8589

There are no patterns directly visible what may typically cause the error. 

The errors occur at least with Python 3.6 system Python on Fedora 26 and a 
self-compiled Python 3.7.3 on a fresh Debian 9 system.

[issue31711] ssl.SSLSocket.send(b"") fails

[Shivaram Lingamneni]

Shivaram Lingamneni  added the comment:

Are there any possible next steps on this?

This issue is very counterintuitive and challenging to debug --- it commonly 
presents as a nondeterministic edge case, and it appears to be a failed system 
call but doesn't show up in strace.

Thanks for your time.

[issue37400] test_os: test_chown() started to fail on AMD64 FreeBSD 10-STABLE Non-Debug 3.* buildbots

[STINNER Victor]

STINNER Victor  added the comment:

I merged my pythoninfo change, more complete pythoninfo from the buildbot:

os.getgid: 1002
os.getgrouplist: 1002
os.getgroups: 1002
os.getuid: 1002

pwd.getpwuid(1002): pwd.struct_passwd(pw_name='buildbot', pw_passwd='*', 
pw_uid=1002, pw_gid=1002, pw_gecos='FreeBSD BuildBot', pw_dir='/home/buildbot', 
pw_shell='/bin/sh')

IMHO the test is wrong: it should rely on os.getgroups() rather tan "discover" 
groups from pw.getpwall().

[issue37400] test_os: test_chown() started to fail on AMD64 FreeBSD 10-STABLE Non-Debug 3.* buildbots

[STINNER Victor]

STINNER Victor  added the comment:

I'm connected to the FreeBSD CURRENT buildbot as the user "haypo". I'm unable 
to reproduce the bug:

CURRENT-amd64% id
uid=1003(haypo) gid=1003(haypo) groups=1003(haypo)

CURRENT-amd64% ./python -m test test_os -m test_chown
(...)
Tests result: SUCCESS

Moreover, it seems like something changes on the buildbot, since the user 
"buildbot" now has 0 group!?

$ ./python
>>> [g.gr_gid for g in grp.getgrall() if 'buildbot' in g.gr_mem]
[]

Or maybe as the user "haypo", I cannot see *all* groups.

In case of doubt, I will blindly apply my fix PR 14374.

It already does :)

This is more likely because the previous build on that buildbot crashed(?) or 
because it was aborted during test_multiprocessing:

[issue37391] MacOS Touchpad scrolling crashes IDLE

[Ned Deily]

Ned Deily  added the comment:

> It seems to be compiled using Tcl 8.5 that is installed with the system.

Yes, and that is almost certainly the original poster's problem, as well.  In 
fact, this same issue was reported in Issue10731 in 2010. The Tcl/Tk 8.5 
supplied by Apple in macOS is terribly out-of-date and dangerously buggy; it 
should never be used.  You should even be seeing a warning message from IDLE 
when using that system Tcl/Tk. I'm not familiar with how Homebrew manages the 
Tcl/Tk that their Pythons link with but, if necessary, you should follow up 
with them to ensure that none of their recipes use the system Tcl/Tk.

More details here:

[issue37391] MacOS Touchpad scrolling crashes IDLE

[George Pantazes]

George Pantazes  added the comment:

Checked against the python.org installation. In that installation's IDLE, About 
IDLE > Tk version 8.6.8.

So my question is: 
- Is it on me to fix this for my own machine because I should have gotten my 
own more-up-to-date TK before installing Python via Homebrew?
- Or is this a Homebrew installation bug? And should they include a more 
up-to-dat TK with their installation?

George,

This is a Homebrew build issue (see additional notes on the Brew forum 
https://discourse.brew.sh/t/cannot-get-python-to-use-tcl-tk-version-8-6/3563.

You may wish to try the suggestions found there. My recommendation would be to 
use the official Python from python.org or the Anaconda distribution for Mac.

[issue37276] Incorrect number of running calls in ProcessPoolExecutor

[Géry]

Géry  added the comment:

@Ned Deily

Okay, I did not know if I had to list the potentially interested people 
(according to their Github contribution on the module for instance) or let them 
do it themselves. Thank you for clarifying.

@Carol Willing

The number of RUNNING futures is always `max_workers + 1` for 
`ProcessPoolExecutor` but only on Windows (CPython 3.7, Windows 10). On MacOS, 
this number varies, depending on the time you wait before calling 
`print(future.running())`.
So to reproduce you could add the expression `time.sleep(n)` right after  the 
statement `futures = [executor.submit(call) for _ in range(8)]` and see if the 
number of RUNNING futures varies with n.

I've been asked enough times about what directory name to use for virtual 
environments I'm going to update 
https://docs.python.org/3/library/venv.html#module-venv to suggest `.venv` if 
you don't have a specific name (`.env` clashes with environment variable

As @willingc notes, it is a Homebrew build issue that should be addressed by

that shortly to see if we can make building with a third-party Tk easier on 
macOS.

[issue37404] asyncio sock_recv blocks on ssl sockets.

[Christian Heimes]

Christian Heimes  added the comment:

You can't use sock_recv() with a wrapped SSL socket. A SSLSocket behaves 
differently because there is user-level buffering. The connection operates on 
TLS frames and only hands off data after it has been decrypted and verified. 
asyncio uses wrap_bio().

[issue37405] socket.getsockname() returns string instead of tuple

[Brent Gardner]

New submission from Brent Gardner :

In Python 3.5.3, a socket with type AF_CAN returns a tuple in the form 
`(interface, )` from getsockname().  In Python 3.7.3, getsockname() returns a 
string (the name of the interface).  The documentation states "a tuple is used 
for the AF_CAN address family".  The string will break code that worked in 
3.5.3 by raising errors such as "Value Error: too many values to unpack 
(expected 2)".

Example:

#3.5.3
import socket
s = socket.socket(socket.AF_CAN, socket.SOCK_RAW, socket.CAN_RAW)
s.bind(('vcan0',)) # requires tuple
s.getsockname() # returns tuple: ('vcan0', 29)

#3.7.3
import socket
s = socket.socket(socket.AF_CAN, socket.SOCK_RAW, socket.CAN_RAW)
s.bind(('vcan0',)) # requires tuple
s.getsockname() # returns string: 'vcan0'

[issue36917] ast.NodeVisitor no longer calls visit_Str

[Tyler Wince]

Tyler Wince  added the comment:

Another example of the breaking change here is in the security linter 
`PyCQA/bandit`. It may be a simple addition of a check in the meta parser for 
the ast but I would tend to agree with Anthony around whether or not it is 
worth it. 

Anyone else have any thoughts on this since the conversation ended last month?

Thanks Pierre Glaser. Let's see if it's enough to make the test more reliable

[issue37276] Incorrect number of running calls in ProcessPoolExecutor

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

All the pending work items are added to a call queue that the processes consume 
(_add_call_item_to_queue) and the status is set before adding it to said queue 
(by calling set_running_or_notify_cancel()). Notice that the fact that 
future.running() == True does not mean that a worker has picked up the work 
item. The worker function (_process_worker for the ProcessPoolExecutor) gets 
items for this queue and then sends back results in another queue (result 
queue). If you add extra debugging you will see that only two items are 
dequeued from the call_queue:


--- a/Lib/concurrent/futures/process.py
+++ b/Lib/concurrent/futures/process.py

Executing your script:

futures = [executor.submit(call) for _ in range(8)]
