[issue34257] SSL should accept cert content, instead of just cert file path

[Jared]

Jared  added the comment:

Also [PEP 543](https://www.python.org/dev/peps/pep-0543/) is related to this. 
In addition, I think [PyOpenSSL](https://pyopenssl.org/en/stable/index.html) 
provides support for what you want.

First off, no judgment! :)

I just want to get some more details from you. 
1) How are you running your program?
2) How far into your program do you get?
3) What are you passing in as values for your Input() calls?

[issue34268] run pool.submit in callback when future.set_result

[gaoxinge]

New submission from gaoxinge :

## abstract

When using concurrent.futures.ThreadPoolExecutor module, if we code pool.submit 
in callback, the callback may be not run. This is because main thread will 
terminate, and call _python_exit to add none to _work_queue before subthread 
run callback.

## code

```
# -*- coding: utf-8 -*-
from concurrent.futures import ThreadPoolExecutor


def func(x, y):
import time
time.sleep(1)
return x + y


def do_many(n):

def callback(fut):
nonlocal n
result = fut.result()
print('Got: ', result)
n -= 1
if n > 0:
future = pool.submit(func, n, n)
future.add_done_callback(callback)

if n > 0:
future = pool.submit(func, n, n)
future.add_done_callback(callback)
 # _python_exit will be called here, and then 
 # add none to _work_queue

pool = ThreadPoolExecutor(max_workers=8)
do_many(10)
```

## result and expectation

The code's result may be 

```
Got:  20
Got:  18
Got:  16
Got:  14
Got:  12
Got:  10
Got:  8
Got:  6
```

But my expectation is

```
Got:  20
Got:  18
Got:  16
Got:  14
Got:  12
Got:  10
Got:  8
Got:  6
Got:  4
Got:  2
```

## question

Is my expectation reasonable?

### if not reasonable

If not, my solution is 

```
from concurrent.futures import ThreadPoolExecutor


def func(x, y):
import time
time.sleep(1)
return x + y


def do_many():

def callback(fut):
global n
result = fut.result()
print('Got: ', result)
n -= 1
if n > 0:
future = pool.submit(func, n, n)
future.add_done_callback(callback)

if n > 0:
future = pool.submit(func, n, n)
future.add_done_callback(callback)

n = 10
pool = ThreadPoolExecutor(max_workers=8)
do_many()
while n > 0:  # use while to block main thread
pass
```

and is there any elegant solution?

### if reasonable

[issue34267] find_python.bat doesn't find installed Python 3.7

[Segev Finer]

New submission from Segev Finer :

The PCbuild/find_python.bat script doesn't find an installed Python 3.7 and 
will proceed to download Python using nuget.

This is caused by it invoking py with "-3.6" which will only find Python 3.6 
(py doesn't seem to support a 3.6 or above flag), despite the fact that the 
build can use 3.7 and the nuget fallback will install 3.7.

[issue33113] Query performance is very low and can even lead to denial of service

[Tim Peters]

Tim Peters  added the comment:

Note:  if you found a regexp like this _in_ the Python distribution, then a bug 
report would be appropriate.  It's certainly possible to write regexps that can 
suffer catastrophic backtracking, and we've repaired a few of those, over the 
years, that shipped with Python.

But we can't stop you from writing such things yourself.  If you post your 
regexp to, e.g., comp.lang.python or StackOverflow, I'm sure someone will show 
you how to rewrite it in a safe way.  But be prepared to explain in English 
what you're trying to accomplish with it.

For example, while it appears you're trying to ensure there are at least 3 
characters (of the right kind) between "|" separators, for some reason you made 
matching "|" optional.  That leaves open an exponential number of ways to try 
to match long strings of non-"|" characters between "|" separators.

I unassigned myself from this a few months ago. If someone wants to fix it, I'm 
not opposed. But the issue is 12 years old and doesn't cause any real problems 
as far as I can see, so it's hard to get excited about it. And as we've seen 
there are a lot of corner cases. I'd hate to make things worse.

[issue34235] PyArg_ParseTupleAndKeywords: support required keyword arguments

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The problem is that PyArg_ParseTupleAndKeywords() supports required 
keyword-only parameters, but only if all parameters are required.

"O|O$O" -- last two are optional.
"OO$O" -- all are required.

This makes designing a consistent syntax more difficult. '|' currently is not 
allowed after '$'. If allow it with the meaning that all arguments before it 
are required, and after it -- optional, this will allow to declare required and 
optional keyword-only parameters, but optional positional-or-keyword parameters 
could not be used in the same function.

[Stefan Behnel]

Stefan Behnel  added the comment:

>> Commutativity guarantees can be delivered by sorting arguments before 
>> summation.

> No thanks -- that's too expensive for such a small payoff.

Since I don't really see people use this on vectors with hundreds of 
dimensions, let me still suggest using insertion sort. It's simple and short to 
implement into the current code (right in the first loop) and should be plenty 
fast for any reasonable usage of this function.

[issue33113] Query performance is very low and can even lead to denial of service

[Tal Einat]

Tal Einat  added the comment:

I suggest closing this as "wontfix".

This is a just an non-optimized regexp pattern leading to long run times.  That 
these are possible is a well-known trait of backtracking regular expression 
engines in general, and ours in particular.

IMO this isn't a security issue since the root of the issue is the pattern.  I 
don't see this as a bug or a significant performance issue either, and there is 
no concrete enhancement suggestion here.

For clarification, the given pattern is equivalent to:
pat = r'''^
(
\(?
[\w\d\-\.\\]{3,}
\|?
)+
[\w\d\-\.\\]{3,}
\)?

[issue33223] test_posix fails ERRNO 0

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I'm slightly closer to understanding the problem. The value of errno is that of 
the last error *before* getgrouplist(3) was called, that is, getgrouplist 
return -1 but does not update errno.

And looking at Apple source code this is a bug in CPython after all: 
getgrouplist(3) return -1 when the buffer is too small, but does not set errno 
(see 
).
 The manpage also doesn't mention setting errno.

I'm pretty sure that the use of posix_error() is wrong here. 

We're running into a similar issue as with getgroups: on macOS a user can be a 
member of more than NGROUPS_MAX groups.  Because of this I'm not yet sure of 
the correct fix for this issue.

The easy part is that the call to posix_error in the implementation of 
getgrouplist should be replaced by raising some other error (or possibly just 
setting errno to EOVERFLOW before calling posix_error()).

The harder part is what to do about the definition of MAX_GROUPS for this 
function. Either force it to a larger default on macOS, or add some code to 
increase the buffer size (because the user cannot select the size of buffer to 
use). The latter is annoyingly hard because the system gives no indication on 
what the correct buffer size should be.

BTW. The same is also true on other platforms with getgrouplist(), this is not 
a macOS specific issue other than that NGROUPS_MAX is bogus there.

[issue33223] test_posix fails ERRNO 0

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I get the same error on High Sierra, but not on the Mojave beta.  I also 
regularly get a FileNotFound error instead (which is why I ended up at this 
issue in the first place).

I'm not sure yet what causes this, a small reproducer in C works correctly and 
the code in posixmodule.c looks correct. This might be a platform bug (hence my 
attempt at writing a reproducer in C).

BTW. There is no attached file

[issue34264] Inconsistency between stack size in main thread and secondary threads on macOS

[Ronald Oussoren]

New submission from Ronald Oussoren :

configure.ac sets the stack size for the main thread on macOS to 100 (hex), 
while Python/threading_pthread.h sets the default stack size for other threads 
to 0x50. The latter is half of the former.

IMHO both should be the same, as both claim to have been chosen to be just 
large enough to accommodate the default recursion limit. 

I'd prefer to increase the default stack size of secondary threads to match the 
main thread. I tagged this as a 3.8 thread because there is a (very) small 
chance that changing the stack size breaks existing programs (although you'd 
have to create a lot of threads to use a significant amount of memory). 

This is vaguely related to issue33955.

The relative imports cannot work, as the main program is not in the test

As Guido said in another bug report, tests are expected to pass. Can you please 
adapt them?

I hope "Library" is proper component, as tests are below it.

[issue34254] Include type annotations in error messages for better errors

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I have added support for functions defined inside a function and methods of a 
class along with some basic tests. Since directly taking co_name from code 
object returns only the name without any context like Foo.square inside square 
when I try to access co_name. So I have passed the function object available at 
the calls as an additional parameter. Since the API is not public or documented 
I think it's okay to add an argument in those places. Thus by directly having 
the function object I am able to get the annotations directly instead of making 
a lookup in the globals.

This approach makes places where TypeError is raised to pass function object 
like too much of positional arguments and keyword arguments type of errors etc. 
The code to form the error string can be refactored out as a helper function 
thus the logic takes a function object and returns the error message. I think 
this would require more changes in places to pass function object than my 
original approach to cover more areas thus adding some complexity.

Thanks

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

I believe Victor is at the EuroPython sprints as well, so if I'm right about 
that, I think the best option would be for the two of you to work out a 
resolution for 3.7.1 in person that at least keeps the test suites reasonably 
consistent, even if the implementations have diverged (the new tests already 
added for bpo-34170 were the main reason I stopped working on my initial patch 
for this).

And agreed on fixing the current dependency inversion between pylifecycle and 
the py_main code - the functions needed by both Py_Main and Py_Initialize 
should be migrated down the stack into pylifecycle as part of the bpo-34170 
work.

[issue34263] asyncio: "relative *delay* or absolute *when* should not exceed one day"

[Yury Selivanov]

New submission from Yury Selivanov :

asyncio documentation has this bit on timeouts:

Timeouts (relative *delay* or absolute *when*) should not exceed one day.

Victor told me that the actual reason for this recommendation is a limitation 
in epoll (or other OS/selector) that prevents us from waiting for events longer 
than a day or so.

The solution to this problem is simple: we need to cap the maximum time we pass 
to the "selector.select()" function (in base_events.py/_run_once) to one day.

[issue34113] LLTRACE segv

[Petr Viktorin]

Petr Viktorin  added the comment:

The problem here is that tracing for STACKADJ prints out the top of the stack 
*after* adjustment. This is OK for growing the stack, but not for shrinking it 
(e.g. calling STACKADJ(-3) pops off three things at once, which can leave TOP 
undefined when it's printed out).

On the EuroPython sprints, I recommended splitting STACKADJ into STACKADJ_GROW 
and STACKADJ_SHRINK, since the printing behavior should be different.
This is performance-critical code; it needs to be reviewed carefully.

[issue34261] Add description to clinic.py

[Tim Hoffmann]

New submission from Tim Hoffmann :

When trying to update a docstring of a CPython builtin, I had problems finding 
out what Argument Clinic actually does.

First, I looked at the devguide, which does only mention that the clinic 
exists, but not what it does or how it's used.

Next, I tried "clinic.py --help". This unfortunately doesn't tell anything 
about itself.

The actual clinic doc is at https://docs.python.org/3/howto/clinic.html

To make the clinic a bit more discoverable, I propose a description including 
the link to clinic.py (see github #8518).

[issue34260] shutil.copy2 is not the same as cp -p

[Zsolt Cserna]

New submission from Zsolt Cserna :

The docstring of shutil.copy2 says the following:

Copy data and all stat info ("cp -p src dst").

This can be misleading as it is not the same as 'cp -p', as it does not copy 
the file owner (uid and gid). That would need to have a chown() call to be 
made, which is currently not called unavailable.

I would like to have the documentation fixed by adding that it does not copies 
file owner and group.

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I've created a pull request that seems to work properly, although I am not 
entirely sure that this is the right way to fix this.

As I mentioned in the pull request I created it against the 3.7 branch because 
of bpo-34170, but would happily rebase it for master.
