[issue38181] some trable with max when np.nan is in the first of a list

[Mark Dickinson]

Mark Dickinson  added the comment:

Right, `max` can only give meaningful results when presented with elements that 
belong to a totally-ordered collection. Unfortunately, floats-including-nan is 
not such a collection (though floats-excluding-nan *is*, provided we ignore 
wrinkles with positive and negative zero).

Here's the source of the issue:

Python 3.7.4 (default, Sep  7 2019, 19:52:29) 
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> 5.0 < np.nan
False
>>> np.nan < 5.0
False

[issue38178] Remove explicit "loop" argument from EchoClientProtocol example

[STINNER Victor]

STINNER Victor  added the comment:

> In modern asyncio code the explicit loop arguments are no longer used since 
> the loop can always be obtained with get_running_loop().

Yeah, the trend changed. Around Python 3.4, passing explicitly loop was 
preferred for best performances.

Since that time, the code to get the current loop has been optimized, and the 
new trend is to make the loop implicit to make the code more readable.

--

When I wrote the doc, self.loop.stop() was called explicitly:

https://docs.python.org/3.5/library/asyncio-protocol.html#tcp-echo-client-protocol

It seems like the example has been modified to add a new "on_con_lost" Future.

--

Anyway, thanks Hrvoje Nikšić for your contribution ;-)

It would be too confusing to have two different approaches to join strings in 
Python. Besides ECMAScript 1 came out in 1997, 5 years after Python was first 
released. By that argument JavaScript that should.

[issue33214] join method for list and tuple

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

How common is the case of variable number of things to concatenate/union/merge?

>From my experience, in most ceases this looks like:

result = []
for ...:
# many complex statements
# may include continue and break
result.extend(items) # may be intermixed with result.append(item)

So concatenating purely lists from some sequence is very special case. And 
there are several ways to perform it.

result = []
for items in seq:
result.extend(items)
# nothing wrong with this simple code, really

result = [x for items in seq for x in items]
# may be less effective for really long sublists,
# but looks simple

result = list(itertools.chain.from_iterable(items))
# if you are itertools addictive ;-)

[issue38185] Weird way of case-insensitive indexing of sqlite3.Row

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

sqlite3.Row can be indexed by integers and by strings. In the latter case 
string matching is case insensitive. But the code that implements this is too 
simple-minded. It compares UTF-8 representation of two strings ignoring some 
bit. It works for ASCII letters, but has weird behavior for digits, '_' and 
non-ASCII characters.

For example:

>>> import sqlite3
>>> con = sqlite3.connect(":memory:")
>>> con.row_factory = sqlite3.Row
>>> row = con.execute("select 1 as a_1").fetchone()
>>> row['a_1']
1
>>> row['A_1']
1
>>> row['A_\x11']
1
>>> row['A\x7f1']
1
>>> row = con.execute("select 1 as ÿ").fetchone()
>>> row["ÿ"]
1
>>> row["Ÿ"]
Traceback (most recent call last):
  File "", line 1, in 
IndexError: No item with that key
>>> row["ß"]
1

[issue33214] join method for list and tuple

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

It is history, but in 1997 Python had the same order of arguments as 
ECMAScript: string.join(words [, sep]). str.join() was added only in 1999 
(226ae6ca122f814dabdc40178c7b9656caf729c2).

[issue38183] test_idle fails on AMD64 FreeBSD CURRENT Shared 3.x: GetUserCfgDir() fails with PermissionError

[Kubilay Kocak]

Kubilay Kocak  added the comment:

This is related to issue 37400 and issue 27838 in that specific invocations of 
the buildbot service (like via sudo) cause the environment to be setup 
differently.

In this case, I had just started the buildbot worker via sudo prior to the 
build starting and failing.

In the #37400 and #27838 cases (see msg295486), sudo was also used, where HOME 
ends up being /root, which is not writeable by the user the worker is run under 
(buildbot).

The test should either mock, or should write to a known temp directory 
(possibly one it creates), either in the build dir, or /tmp or similar, though 
I'd lean towards keeping all test writes within the scope of the temporary 
build location

I can either

1) if the issue cannot be resolved in short order, restart the worker now to 
clear the problem, until this issue has a changeset against it to resolve it

2) if it can be resolved in short order, leave the worker in this state until 
fixed

[Steve Dower]

Steve Dower  added the comment:

I've published the sources and binaries for Windows - will get to updating the 
3.9/3.8/3.7 branches later today unless someone else does first (should just 
require version number changes).

[issue38186] Use FindFirstFile in ntpath.realpath() when access is denied

[Steve Dower]

New submission from Steve Dower :

There remains a case in ntpath.realpath() where a (handled) ERROR_ACCESS_DENIED 
or ERROR_SHARING_VIOLATION will break out of traversing a series of paths.

However, in this case (in os.stat(), for example), we could request the real 
name of the file from the directory using FindFirstFileW. This would correct 
the case and remove any path shortening (e.g. LONGFI~1 to LongFilename) without 
needing to directly access the file.

[issue38188] Incorrect Argument Order for Calls to _winapi.DuplicateHandle() in multiprocessing.reduction.DupHandle

[Cameron Kennedy]

New submission from Cameron Kennedy :

The DuplicateHandle function is utilized by the DupHandle object to duplicate 
handles for the purpose of sending and receiving between processes on Windows 
systems. At least on Python 3.7.3, this function is invoked with an incorrect 
argument order. In multiprocessing.reduction, send_handle passes 
_winapi.DUPLICATE_SAME_ACCESS as the access argument to the DupHandle 
constructor, which in-turn passes it to the access argument for 
_winapi.DuplicateHandle(). Instead, per 
https://docs.microsoft.com/en-us/windows/win32/api/handleapi/nf-handleapi-duplicatehandle
 this constant should be passed into the options argument. This bug results in 
any handles communicated via this method to have meaningless permissions set, 
which makes them unusable. 

I've monkeypatched the issue with the following code:

send_handle=_patched_send_handle

The above seems to fix the problem on my machine by adding an additional 
options property to the DupHandle object and an options argument to send_handle 
function.

[issue38189] pip does not run in virtual environment in 3.8

[Jonathan Gossage]

New submission from Jonathan Gossage :

Python 3.8 was installed from source on Ubuntu 19.04 desktop and a virtual 
environment was created with python3.8 -m venv venvrh. When attempting to use 
pip to install a package, the following error was encountered:

[Ammar Askar]

Ammar Askar  added the comment:

As the error says:

> Can't connect to HTTPS URL because the SSL module is not available.

Since you built it from source, you should check your build logs, the _ssl 
module likely failed to build. You're most probably missing the openssl 
dependency.

[issue38189] pip does not run in virtual environment in 3.8

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I guess it's due to the binary not being built with ssl module. During build 
did you get a message like below ? 


Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with 
X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, 
https://github.com/libressl-portable/portable/issues/381

In the REPL you can verify it by trying to import ssl module that would fail if 
python was not built with ssl

[Stéphane Wirtel]

Stéphane Wirtel  added the comment:

I close this issue, it's not related to the packaging of Python, but just to 
your compilation.

As explained by Ammar Askar, when you compile Python, you have to be sure that 
you have the openssl-dev package installed on your system

[issue38183] test_idle fails on AMD64 FreeBSD CURRENT Shared 3.x: GetUserCfgDir() fails with PermissionError

[Terry J. Reedy]

Terry J. Reedy  added the comment:

>From IDLE's viewpoint, the 2.7 failures are the same.  In current 3.x, 
>GetUserCfgDir has

warn = ('\n Warning: unable to create user config directory\n' +
userDir + '\n Check path and permissions.\n Exiting!\n')
if not idlelib.testing:
print(warn, file=sys.stderr)
raise SystemExit

In 2.7. the conditional clause is not there because idlelib.testing does not 
exist.  It was added to avoid 3.x regrtest resource-changed checks that either 
were not backported to 2.7 or are not triggered by the smaller 2.7 set of IDLE 
tests.

The irony of the failures is that the tests are carefully written to pass 
regardless of user config values, if any, and never alter them.  Only 
test_config and test_configdialog actually *need* to access the config 
machinery.  Other tests could mock idleConf.

PR 16198 has a minimal fix that works on my Windows machine.  A 2.7 backport, 
which must be manual, will require the addition of idlelib.testing and its 
setting it test_idle.  I will wait for passes from buildbots, not just the CI.

Followup issues:

0. For 'other tests', mock idleConf and run a bit faster.

1. If ignoring .idlerc this way works, simplify some of the tests by setting 
idlelib.testing to True instead of duplicating what IdleConf will now  do.

2. Minimally implement "# TODO continue without userDIr instead of exit".  
Replace "raise SystemExit" with "return ''" and add warnings that configuration 
changes will disappear when exiting IDLE.

[issue38191] typing.NamedTuple() should prefix parameters with '_'

[Glenn Gribble]

New submission from Glenn Gribble :

At present, it is not possible to use the shorthand notation to define a 
NamedTuple with typename or fields.  I.e., NamedTuple('MyTuple', typename=str, 
fields=int) does not work.  Changing the parameter names to _typename and 
_fields would allow any non-private, legal identifier to be used in the 
shorthand notation.
  
>>> import typing
>>> typing.NamedTuple('Example', fieldz=int)

>>> typing.NamedTuple('Example2', fields=int)
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Program Files\Python37\lib\typing.py", line 1411, in __new__
return _make_nmtuple(typename, fields)
  File "C:\Program Files\Python37\lib\typing.py", line 1326, in _make_nmtuple
types = [(n, _type_check(t, msg)) for n, t in types]
TypeError: 'type' object is not iterable


Of course, it is fairly easy to work around the issue by using fields parameter:

>>> typing.NamedTuple('Example3', [('fields', int)])



There would be backwards compatibility issues with any code using named 
arguments for fields or typename.

[issue38162] Import Long Load

[STINNER Victor]

STINNER Victor  added the comment:

tempfile uses a low number of random bits per filename, so collision is 
"likely". Two Python processes might attempt to create the same temporary file 
"at the same time". Maybe not two processes, but two Python threads.

Rather than writing complex locking mechanism, "for seq in range(TMP_MAX):" 
retries. While one collision is "likely", TMP_MAX is less likely, especially if 
TMP_MAX is big.

On my Linux, I get:

pvstinner@apu$ python3
Python 3.7.4 (default, Jul  9 2019, 16:32:37) 
>>> import posix
>>> posix.TMP_MAX
238328

Removing the loop introduces a race condition. You tagged this issue as 
"performance": well, in Python we don't accept optimizations which make Python 
"not correct". Correctness matters more than performance.

If tempfile is critical for your application performance, you can easily copy 
tempfile.py and adapt it for your needs ;-)

Well, as Stéphane wrote: you need to eloborate the rationale for your change.

[issue38190] regrtest: test suite completes but Tests Result is not displayed and the process hangs

[STINNER Victor]

STINNER Victor  added the comment:

> command timed out: 1200 seconds without output running ['make', 
> 'buildbottest', 'TESTOPTS=-j2 -j4 ${BUILDBOT_TESTOPTS}', 'TESTPYTHONOPTS=', 
> 'TESTTIMEOUT=900'], attempting to kill

faulthandler is supposed to display the traceback where the test hangs, but for 
the main process, libregrtest uses a delay of timeout x 2 seconds:

self.worker_timeout = self.ns.timeout * 1.5
self.main_timeout = self.ns.timeout * 2.0

Here timeout=900 ("TESTTIMEOUT=900"), so main_timeout = 1800 seconds (30 
minutes), whereas buildbot timeout is 1200 seconds (20 minutes) :-(

In fact, main_timeout can be *way* shorter: the main process calls 
faulthandler.dump_traceback_later(self.main_timeout, exit=True) every 
max(PROGRESS_UPDATE, PROGRESS_MIN_TIME) seconds (or more often): every 30 
seconds (of more often).

So main_process could be max(PROGRESS_UPDATE, PROGRESS_MIN_TIME) x 2 = 1 
minute, instead of 30 minutes.
