[issue41723] doc: issue in a sentence in py_compile

[Sean Chao]

New submission from Sean Chao :

I think in 
https://docs.python.org/3.10/library/py_compile.html#py_compile.compile
the sentence:
> If dfile is specified, it is used as the name of the source file in error 
> messages when instead of file.
should not have the 'when'.

[issue41719] Why does not range() support decimals?

[Raymond Hettinger]

Raymond Hettinger  added the comment:

FWIW, the usual approach to the OP's problem is:

>>> [x*0.5 for x in range(10)]
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5]

This technique generalizes to other sequences as well:

>>> [x**2 for x in range(10)]
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

As Steven points out, numeric work typically requires something different and a 
bit more sophisticated.  The numpy package may be your best bet for this kind 
of work.

[issue41719] Why does not range() support decimals?

[Steven D'Aprano]

Steven D'Aprano  added the comment:

Generating a range of equally-spaced floats is tricky and the range builtin is 
not the right solution for this.

For numerical work, we often need to specify the number of steps, not the step 
size. For instance, in numeric integration, we often like to double the number 
of steps and avoid re-calculation.

We often need to skip either the start or end point, or both, or neither.

If you specify the step size, as range does, you can have off-by-one errors due 
to float rounding.

See here for a discussion and possible solution:

[issue41718] test.regrtest has way too many imports

[Terry J. Reedy]

Terry J. Reedy  added the comment:

On Windows with current master, the baseline for running anything with 1 import 
(">>>  import sys; len(sys.modules)") is 35 imported modules.  Adding "import 
unittest" increases this to 80.  What slightly puzzles me is that running 
---
import unittest
import sys

class Tests(unittest.TestCase):
def test_bug(self):
print("len(sys.modules):", len(sys.modules))

if __name__ == "__main__":
unittest.main()
---
increases the number to 90.  Perhaps unittest has delayed imports.

The current startup number for IDLE is 162, which can result in a cold startup 
of several seconds.  I am thinking of trying to reduce this by delaying imports 
of modules that are not immediately used and might never be used.

For tests, I gather that side-effect issues are more important than startup 
time.

[issue41627] Relocate user site packages on Windows 32-bit

[Steve Dower]

Steve Dower  added the comment:

> With the change in PR 22098, the 32-bit interpreter will install to a

To clarify this, I meant the 32-bit interpreter will install *packages* to a 
different location (when using the user scheme).

[issue41719] Why does not range() support decimals?

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The original title was "Why does not range() support decimals?".  In general, 
such questions should be directed to question forums, such as 
https://mail.python.org/mailman/listinfo/python-list or stackoverflow.com.

This question has been answered on both, with alternatives, in particular on
https://stackoverflow.com/questions/477486/how-to-use-a-decimal-range-step-value
https://stackoverflow.com/questions/12403411/range-with-float-step-argument
and other duplicates.

I am leaving this open to add this frequent question to our FAQ, in particular 
at
https://docs.python.org/3/faq/programming.html#sequences-tuples-lists
with 'range' added.

This answer should include how to use range to get what people generally want.

[issue41722] multiprocess error on large dataset

[issue41659] PEG discrepancy on 'if {x} {a}: pass'

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Minimal example
>>> a{ # or
>>> a {
In 3.8, this is immediately flagged as a SyntaxError.  In 3.9 and master, a 
continuation prompt is issued.  This strikes me as a parsing buglet that should 
preferably be fixed, as it implies that something valid *could* follow '{', 
thus misleading beginners.  On the other hand, after scanning my keyboard, '{' 
seems unique in being a legal symbol, unlike `, $, and ?, or combinations like 
+*, that can AFAIK never follow a name.  So it would need special handling.


Side note: for the same reason I dislike the { change, I like the generic 3.9 
change for legal operators without a second operand. 
>>> a *
Both flag as SyntaxError, but in 3.8, the caret is under '*', falsely implying 
that '*' cannot follow a name, while in 3.9, it is under the whitespace 
following, correct implying that the * is legal and that the problem is lack of 
a second expression (on the same line without continuation).

[issue35228] Index search in CHM help crashes viewer

[Steve Dower]

Steve Dower  added the comment:

So I found the "owner" of the HTML Help component in Windows (I put owner in 
quotes because this tool is _very_ maintenance mode, so nothing short of a 
critical vulnerability is going to be touched) and he helped me do some 
debugging.

In short, the index file is either corrupt, or it is not parsed correctly. I 
can reliably reproduce the crash with the following steps:

1. Open the Python docs
2. Switch to the Index tab
3. Double-click on any second-level (indented) entry
4. Modify the text in the Index search box

We haven't yet gone deep enough to be able to tell whether the help compiler is 
at fault, or the loader.

If anyone has the time and inclination, testing with older versions (if you can 
find them) of the HTML Help compiler may find a version that works. 
Unfortunately, the older copies we used to use were on the Subversion server, 
which is long gone now.

Alternatively, if anyone knows of a similar tool that we can redistribute 
easily with CPython (i.e. it's not as big as Zeal) and is significantly better 
than just using the user's default browser, I'd be interested to hear about it 
(as would the rest of the developer world, I'm sure - this is a fairly popular 
format!).

[issue41721] xlc: add -qalias=noansi -qmaxmem=-1

[Stefan Krah]

Stefan Krah  added the comment:

The code example is for 64-bit Linux with sizeof(long) == sizeof(long long).

It also works on 32-bit xlc with int/long.

[issue41627] Relocate user site packages on Windows 32-bit

[Steve Dower]

Steve Dower  added the comment:

> If it is otherwise possible to user-only install both 32 and 64 bit versions, 
> then using the same site-packages strikes me a bug

It's very easy to install both 32 and 64-bit runtimes (and it doesn't matter if 
they're user or system installs).

But when you're installing packages in the nt_user scheme (--user with pip), 
you can only use one or the other. If you install with 32-bit runtime first, 
then you'll get 32-bit binaries installed and the 64-bit runtime won't try and 
install the package again (or it'll delete it and replace it with one that only 
works with the 64-bit runtime).

With the change in PR 22098, the 32-bit interpreter will install to a different 
location.

[issue41704] logging module needs some form of introspection or debugging support

[Jack Jansen]

Jack Jansen  added the comment:

@vinay, absolutely right on this being an anti-pattern:-)

And also right on the statement that I can set a breakpoint on all three of 
logging.basicConfig, logging.config.fileConfig and logging.config.dictConfig, I 
had overlooked that (was looking for a single place to put the breakpoint).

I'll close this.

static int
f(long *a, long long *b)
{
 int t = *a;
 *b = 0;  // cannot change *a
 return *a - t;   // can be folded to zero
}

int
main(void)

long a = 10;

printf("%d\n", f(, (long long *)));

return 0;

[issue26214] textwrap should minimize number of breaks in extra long words

[Irit Katriel]

Irit Katriel  added the comment:

To clarify, this solution is a linear-time greedy one, with three passes:
- the first pass puts each long word on its own line. 
- the second pass chops them up into words of at most width characters.
- the third pass wraps them, when there are no more long words.

This minimizes the number of breaks within words. It doesn't minimize the 
number of output lines (you'd need a dynamic programming programming algo for 
that - O(n^2)). So for this input:

wr("123 12 123456 1234", 5)

you will get 
['123', '12', '12345', '6', '1234']

where you may (or may not) have preferred:

['123', '12 1', '23456', '1234']

[issue41710] Timeout is affected by jumps in system time

[Jonas Norling]

Jonas Norling  added the comment:

sys.thread_info = sys.thread_info(name='pthread', lock='semaphore', 
version='NPTL 2.31') on my system. Looking at the source I think the semaphore 
implementation will be used on all modern Linux systems.

In my tests it works as expected on a Macintosh (3.8.5 with lock='mutex+cond') 
and also if I force a Linux build to use the mutex+cond implementation by 
defining HAVE_BROKEN_POSIX_SEMAPHORES.

Doesn't look like those glibc and Linux bug reports will get any attention 
anytime soon. I will find a workaround instead :-/

I've considered DoSing myself a few times, but then change my mind and just 
publish the release :)

A PR to change it to "(\d+\.\d+\.\d+)([a-zA-Z]+\d+)?$" would be fine, but is 
not urgent. It certainly doesn't need to be backported, as this is only ever 
used from master these days.

Personally I'd be just as happy closing the issue. I know that the current 
script works, and there's nothing worse than breaking a release because someone 
has changed the release scripts without testing them properly.

[issue41718] test.regrtest has way too many imports

[STINNER Victor]

STINNER Victor  added the comment:

In general, it's nice to have the following 4 checks:

* multiprocessing.process._dangling
* asyncio.events._event_loop_policy
* urllib.requests._url_tempfiles
* urllib.requests._opener

The problem is that because of these checks, **any** unit test file of the 424 
Python test files import asyncio, multiprocessing and urllib. As a result, 
**any** unit test starts with around 233 imported modules. We are far from an 
"unit" test, since many modules have side effects.

I wrote PR 22089 to remove these checks. "import test.libregrtest" is reduces 
from 233 to only 149 imports (on Linux), which is way better.

I would prefer to better isolate tests: test_threading should only test the 
threading module, not the logging module.

Thanks to the hard work of Hai Shi, "import test.support" now imports only 37 
modules instead of 171! He split the 3200 lines of Lib/test/support/__init__.py 
into new helper submodules: bytecode, import, threading, socket, etc. For 
example, TESTFN now comes from test.support.os_helper.
Sadly, test.regrtest.save_env still imports asyncio and multiprocessing, and so 
in practice, running any test using "python -m test (...)" still imports around 
233 modules :-(

I measured the number of imports done in practice using the following file, 
Lib/test/test_sys_modules.py:

import unittest
from test import support
import sys

class Tests(unittest.TestCase):
def test_bug(self):
modules = sorted(sys.modules)
print("sys.modules:")
print("")
import pprint
pprint.pprint(modules)
print("")
print("len(sys.modules):", len(modules))

def test_main():
support.run_unittest(Tests)

if __name__ == "__main__":
test_main()


master:

* ./python -m test test_sys_modules: 233 modules (multiprocessing, asyncio, 
etc.)
* ./python Lib/test/test_sys_modules.py: 95 modules

3.9:

* ./python -m test test_sys_modules: 232
* ./python Lib/test/test_sys_modules.py: 117

3.5:

* ./python -m test test_sys_modules: 167
* ./python Lib/test/test_sys_modules.py: 151

2.7:

* ./python -m test test_sys_modules: 170
* ./python Lib/test/test_sys_modules.py: 122

[issue21987] TarFile.getmember on directory requires trailing slash iff over 100 chars

[STINNER Victor]

STINNER Victor  added the comment:

> Any updates on this?

So far, nobody proposed a pull request. So no, there is no update.

Someone has to step in, dig into the issue, propose a fix, then someone else 
has to review the PR, and finally the PR should be merged.

[issue41717] [AIX] test_io: files was modified by test_io: (@test_6488748_tmpæ) on POWER6 AIX 3.9

[STINNER Victor]

New submission from STINNER Victor :

'@test_6488748_tmpæ' is likely TESTFN_NONASCII which is exposed as 
test.support.os_helper.TESTFN, but test_io has many many tests using TESTFN.

https://buildbot.python.org/all/#/builders/330/builds/20

0:06:47 [130/425/1] test_io failed (env changed) (1 min 8 sec) -- running: 
test_concurrent_futures (31.1 sec)
(...)
Warning -- files was modified by test_io
  Before: []
  After:  ['@test_6488748_tmpæ']

Since build 1, 19 days ago:
https://buildbot.python.org/all/#/builders/330/builds/1


If someone is able to reproduce the issue, please attempt to identify which 
test method leaks the temporary file using the command:

./python -m test.bisect_cmd test_io --fail-env-changed -v

After 10-20 minutes, the command should give the name of a single method which 
creates the temporary file.

[issue26214] textwrap should minimize number of breaks in extra long words

[Irit Katriel]

Irit Katriel  added the comment:

You can do this already with the break_long_words arg of testwrap:

>>> import itertools, textwrap
>>> wr = textwrap.wrap
>>> list(itertools.chain(*(wr(x, 5) for x in wr("123 123 1234567", width=5, 
>>> break_long_words=False
['123', '123', '12345', '67']

Serhiy Storchaka  added the comment:

I would use

   NAME_RE = re.compile(r'(?![_\d]+\Z)(?!\d)\w+', re.ASCII)

or

   NAME_RE = re.compile(r'(?=.*[A-Za-z])(?!\d)\w+', re.ASCII)

and NAME_RE.fullmatch() instead of NAME_RE.match().

But why identifiers not containing letters are disabled at first place? Is _123 
an invalid identifier in C?

[issue41714] multiprocessing.Queue deadlock

[Richard Purdie]

Richard Purdie  added the comment:

Even my hack to call _writer.close() doesn't seem to be enough, it makes the 
problem rarer but there is still an issue. 
Basically, if you call cancel_join_thread() in one process, the queue is 
potentially totally broken in all other processes that may be using it. If for 
example another has called join_thread() as it was exiting and has queued data 
at the same time as another process exits using cancel_join_thread() and exits 
holding the write lock, you'll deadlock on the processes now stuck in 
join_thread() waiting for a lock they'll never get.
I suspect the answer is "don't use cancel_join_thread()" but perhaps the docs 
need a note to point out that if anything is already potentially exiting, it 
can deadlock? I'm not sure you can actually use the API safely unless you stop 
all users from exiting and synchronise that by other means?

[issue41715] REDoS inc_analyzer

[yeting li]

New submission from yeting li :

Hi,

I find this regex "^([a-zA-Z]|_\w*[a-zA-Z]\w*|[a-zA-Z]\w*)$" may be stucked by 
input.
The vulnerable regex is located in
https://github.com/python/cpython/blob/54a66ade2067c373d31003ad260e1b7d14c81564/Tools/c-analyzer/c_analyzer/common/info.py#L12

The ReDOS vulnerability of the regex is mainly due to the sub-pattern 
\w*[a-zA-Z]\w*
and can be exploited with the following string
"_" + "a" * 5000 + "!"


I think you can limit the input length or fix this regex.


Looking forward for your response​!

Best,
Yeting Li
