[issue41695] http.cookies.SimpleCookie.parse could not parse cookies when one cookie value is json

Perhaps this is a duplicate of Issue 27674, where I think parsing is aborted 
when a double-quote is seen?

[issue41697] Heap buffer overflow in the parser

[Guido van Rossum]

Guido van Rossum  added the comment:

Smaller repro:

./python.exe -m configparser

Bisection shows that this is the call that causes the crash (line 1301):

return _impl(self._name, option, raw=raw, vars=vars,
 fallback=fallback, **kwargs)

But just that line doesn't trigger this -- apparently *everything* that came 
before it in that file is implicated. Or at least *something* that I haven't 
found yet.

Sorry for the play-by-play...

[issue41699] Potential memory leak with asyncio and run_in_executor

[Sophia Wisdom]

New submission from Sophia Wisdom :

The below example leaks ~20 megabytes of memory. The amount leaked is related 
to both the number of items in the list and the number of times 
`run_in_executor` is called.

```
import asyncio

def leaker():
x = list(range(int(1000)))
1/0

async def function():
loop = asyncio.get_running_loop()
for i in range(1):
loop.run_in_executor(None, leaker)
```
at this point, `ps -o rss -p {pid}` outputs about 10MB

after invoking this:
```
asyncio.run(function())
```
Memory jumps to about 94MB, and doesn't return.

The lists don't show up in `gc.get_objects()`, but the amount of memory leaked 
does increase (though not proportionately) when the lists increase in size.

Note - this doesn't happen if `run_in_executor` is `await`ed immediately, but 
it does still occur if we e.g. put the future in a dictionary and then `await` 
the results later.
The leak still occurs on my machine if the `1/0` is omitted, but not on a 
colleague's.

We're pretty confused as to why this happens, and would appreciate any help.

[issue41698] io.[Text]IOBase.seek doesn't take keyword parameter - revisited

[Andy Maier]

New submission from Andy Maier :

I stumbled across the problem reported in https://bugs.python.org/issue25030 on 
Python 3.8:

>>> with open('x.txt', 'a') as fp:
...   fp.seek(0, whence=os.SEEK_END)
... 
Traceback (most recent call last):
  File "", line 2, in 
TypeError: seek() takes no keyword arguments

Which I coded with a keyword argument because the documentation says so:

   seek(offset, whence=SEEK_SET)

See https://docs.python.org/3.8/library/io.html#io.IOBase.seek

The fix for issue issue25030 changed the documentation to:

   seek(offset[, whence])

and supposedly was integrated into 2.7, 3.4, and the default branch back then.

It seems the fix got lost?

[issue41697] Heap buffer overflow in the parser

[Brad Larsen]

New submission from Brad Larsen :

It looks like commit 4a97b1517a6b5ff22e2984b677a680b07ff0ce11 introduced a heap 
buffer overflow:

commit 4a97b1517a6b5ff22e2984b677a680b07ff0ce11 (HEAD -> master, 
origin/master, origin/HEAD)
Author: Pablo Galindo 
Date:   Wed Sep 2 17:44:19 2020 +0100

bpo-41690: Use a loop to collect args in the parser instead of 
recursion (GH-22053)

This program can segfault the parser by stack overflow:

```
import ast

code = "f(" + ",".join(['a' for _ in range(10)]) + ")"
print("Ready!")
ast.parse(code)
```

the reason is that the rule for arguments has a simple recursion when 
collecting args:

args[expr_ty]:
[...]
| a=named_expression b=[',' c=args { c }] {
[...] }


If you try building with clang-10 with `--with-pydebug 
--with-address-sanitizer`, you should see a crash like the following during the 
`generate-posix-vars` step:

[issue41696] asyncio.run interacts surprisingly with debug mode

[Yury Selivanov]

Yury Selivanov  added the comment:

Yes, this is a bug. The default for the `debug` parameter should be `None` and 
it should only call `loop.set_debug` if a non-None bool value was explicitly 
passed. Care to submit a PR?

[issue41696] asyncio.run interacts surprisingly with debug mode

[Shantanu]

New submission from Shantanu :

To quote the docs (https://docs.python.org/3/library/asyncio-dev.html):

```
By default asyncio runs in production mode. In order to ease the development 
asyncio has a debug mode.

There are several ways to enable asyncio debug mode:

Setting the PYTHONASYNCIODEBUG environment variable to 1.

Using the -X dev Python command line option.

Passing debug=True to asyncio.run().

Calling loop.set_debug().
```

Unfortunately, this documentation is misleading (or wrong) when using 
asyncio.run. For instance, from a naive read of the above, I'd expect debug 
mode to be True for many of the following:

```
~/tmp λ cat test57.py
import asyncio
import time

async def foo():
loop = asyncio.get_event_loop()
time.sleep(2)
print(loop.get_debug())

print(asyncio.coroutines._DEBUG)
asyncio.run(foo())
~/tmp λ python3 --version   
Python 3.7.3

# expected
~/tmp λ python3 test57.py
False
False

# surprising, would expect this to work
~/tmp λ python3 -X dev test57.py
True
False

# surprising, would expect this to work
~/tmp λ PYTHONASYNCIODEBUG=1 python3 test57.py
True
False

# expected
~/tmp λ vim test57.py
~/tmp λ cat test57.py
import asyncio
import time

async def foo():
loop = asyncio.get_event_loop()
time.sleep(2)
print(loop.get_debug())

print(asyncio.coroutines._DEBUG)
asyncio.run(foo(), debug=True)
~/tmp λ python3 test57.py   
False
True
Executing  result=None 
created at 
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/asyncio/base_events.py:563>
 took 2.003 seconds
~/tmp λ 
```

This appears to be because asyncio.run sets debug mode here: 
https://github.com/python/cpython/blob/4a97b1517a6b5ff22e2984b677a680b07ff0ce11/Lib/asyncio/runners.py#L42

We should either change asyncio.run to use the existing value of debug mode if 
left unspecified, or we should update the documentation to explicitly call out 
that the environment variable and command line flag will not work when using 
asyncio.run

[issue41694] python3 futures.as_completed timeout broken if future contains undefined reference

[Josh Rosenberg]

Josh Rosenberg  added the comment:

The problem is a lot simpler than you're making it:

1. You submit a time.sleep(30) task. This begins running immediately
2. You try to submit another task, but a NameError is raised, bypassing the 
rest of the code (you never call as_completed, with or without a timeout)
3. The ThreadPoolExecutor's __exit__ is invoked, which implicitly invokes 
shutdown(wait=True). This does not return until the successfully submitted task 
(time.sleep(30)) finished.
4. At that point, the exception that was interrupted by with statement cleanup 
resumes bubbling

All of this is behaving exactly as documented, no bug is occurring.

I was able to reproduce the crash in python 2.7, but in Python 3.10 (after I 
changed to import PipeConnection from multiprocessing.connection instead of 
_multiprocessing), it doesn't crash but raises an exception that makes sense 
when the handle is 0:

[issue41686] C++ Embedded 'time.sleep()' is not working on Windows host due to 'Py_InitializeEx(0)'

[Steve Dower]

Steve Dower  added the comment:

> Could sigint_event be relocated to a platform-dependent extension of

This, or leaving it where it is and making sure it gets initialised (it really 
is about emulating certain signals). Either sounds fine to me.

[issue41694] python3 futures.as_completed timeout broken if future contains undefined reference

[Dallas Marlow]

Dallas Marlow  added the comment:

I apologize for all the messages, but the more I look into this issue the 
stranger it seems. The following code does the following:

- print the time
- execute 3 futures (2 w/ 30s sleeps)
- call as_completed
- catch the timeout exception
- print the time again
- then raise the timeout exception, but only after all futures complete.

the second time print executes after the as_completed timeout duration, but the 
exception was only raised after all futures completed. the exception message 
incorrectly states that it left 2/3 futures unfinished.

#

import concurrent.futures
import time

with concurrent.futures.ThreadPoolExecutor() as ex:
print(time.time())
futures = [
ex.submit(time.sleep, 30),
ex.submit(time.sleep, 30),
ex.submit(print, 'test'),
]
try:
for future in concurrent.futures.as_completed(
futures, timeout=1):
_ = future.result()
except Exception as e:
print(time.time())
raise e

[issue41631] _ast module: get_global_ast_state() doesn't work with Mercurial lazy import

[STINNER Victor]

STINNER Victor  added the comment:

At commit ac46eb4ad6662cf6d771b20d8963658b2186c48c ("bpo-38113: Update the 
Python-ast.c generator to PEP384 (gh-15957)"):

=> I investigated bpo-41194 crash again. It seems like the root issue is more 
than PyInit__ast() returns a *borrowed* reference, rather than a strong 
reference.

=> The _ast module can only be loaded once, astmodule_free() and 
astmodule_clear() are not called at Python exit.

* bpo-41631 => ok: PyAST_Check() doesn't import the module, it uses a global 
state.
* bpo-41261 => ERROR: This implementation allows to create two instances of the 
_ast module, but also to unload one instance (call astmodule_free), because

[issue41695] http.cookies.SimpleCookie.parse could not parse cookies when one cookie value is json

[Benoît Brayer]

New submission from Benoît Brayer :

Using python3.8.5, SimpleCookie parser seems to be unable to load the cookie 
string when a json string is used inside one of the cookie values.

I did not try to replay using other python3 versions yet.

Please use the following code to replay the bug:

>>> from http import cookies
>>> cookie_parser = cookies.SimpleCookie()
>>> cookie_parser.load('CookieScriptConsent={"action":"accept"}; 
>>> __stripe_mid=plip; __stripe_sid=plop; _ga=tada; _gcl_au=pouet; _hjid=hello; 
>>> authn_token=mylogin; rememberMe=true')
>>> cookie_parser.keys()
dict_keys([])
>>> cookie_parser = cookies.SimpleCookie()
>>> cookie_parser.load('__stripe_mid=plip; __stripe_sid=plop; _ga=tada; 
>>> _gcl_au=pouet; _hjid=hello; authn_token=mylogin; rememberMe=true')
>>> cookie_parser.keys()
dict_keys(['__stripe_mid', '__stripe_sid', '_ga', '_gcl_au', '_hjid', 
'authn_token', 'rememberMe'])

[issue41694] python3 futures.as_completed timeout broken if future contains undefined reference

[Dallas Marlow]

Dallas Marlow  added the comment:

After closer inspection it seems as though timeouts are not working as I would 
expect even when there are no undefined references. The following code runs for 
30s when I would expect a timeout exception thrown after 1 second. as_completed 
eventually does throw a timeout exception, but only after the sleep future 
completes.

###

import concurrent.futures
import time

with concurrent.futures.ThreadPoolExecutor() as ex:
futures = [
ex.submit(time.sleep, 30),
ex.submit(print, 'test'),
]
for future in concurrent.futures.as_completed(futures, timeout=1):
_ = future.result()

[issue41694] python3 futures.as_completed timeout broken if future contains undefined reference

[Dallas Marlow]

New submission from Dallas Marlow :

I recently noticed that timeouts do not work with futures.as_completed if a 
future contains an undefined variable or method. The following code runs for 30 
seconds which I believe is a bug as I would expect the invalid print future to 
throw an exception immediately or the as_completed method throw an exception 
instead.

#

import concurrent.futures

with concurrent.futures.ThreadPoolExecutor() as ex:
futures = [
ex.submit(time.sleep, 30),
ex.submit(print, a),
]
for future in concurrent.futures.as_completed(futures, timeout=1):
_ = future.result()

[issue41692] Deprecate immortal interned strings: PyUnicode_InternImmortal()

[STINNER Victor]

New submission from STINNER Victor :

Python has the concept of "immortal" interned strings: 
PyUnicode_InternImmortal().

The feature was first introduced in the Python 2 "str" (bytes) type, bpo-576101 
(commit 45ec02aed14685c353e55841b5acbc0dadee76f8). New 
PyString_InternImmortal() function.

commit 45ec02aed14685c353e55841b5acbc0dadee76f8
Author: Guido van Rossum 
Date:   Mon Aug 19 21:43:18 2002 +

SF patch 576101, by Oren Tirosh: alternative implementation of
interning.  I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged.  Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.

Later, the feature was added to the PyUnicodeObject type, new 
PyUnicode_InternImmortal() function:

commit 1680713e524016d93a94114c4a874ad71a090b95
Author: Walter Dörwald 
Date:   Fri May 25 13:52:07 2007 +

Add interning of unicode strings by copying the functionality from
stringobject.c.

Intern "True" and "False" in bool_repr() again as it was in the
8bit string era.

Since Python 3.10, (mortal) interned strings are cleared at Python exit in 
Py_Finalize(). It avoids leaking memory when Python is embedded in an 
application: bpo-1635741.

commit 666ecfb0957a2fa0df5e2bd03804195de74bdfbf
Author: Victor Stinner 
Date:   Thu Jul 2 01:19:57 2020 +0200

bpo-1635741: Release Unicode interned strings at exit (GH-21269)

* PyUnicode_InternInPlace() now ensures that interned strings are
  ready.
* Add _PyUnicode_ClearInterned().
* Py_Finalize() now releases Unicode interned strings:
  call _PyUnicode_ClearInterned().

--

PyUnicode_InternImmortal() is not used in the Python standard library. I 
propose to start deprecating the function and remove it in Python 3.12 (PEP 387 
requires a deprecation for 2 releases). In Python 3.10, calling the function 
will emit a DeprecationWarning at runtime.

Note: PyString_InternImmortal() (for bytes strings) has been removed from 
Python 3.0.

[issue41642] Buildbot: workers detached every minute and "no space left on device" issue

[STINNER Victor]

STINNER Victor  added the comment:

Charris, Pablo and me identified that TCP connections are closed by the load 
balancer on some buildbot workers.

When the "buildbot.python.org" host name is used, TCP connections (tcp port 
9020) go through a load balancer.

Ernest exposed the TCP port 9020 directly to the Internet (without the load 
balancer) using a new host name: "buildbot-api.python.org".

Buildbot workers should be updated to use "buildbot-api.python.org". I also 
suggest to use a keepalive of 60 seconds, rather than 600 seconds.

If your worker got impacted the this issue, I strongly advice you to clean up 
manually the temporary directory (/tmp). When a worker was disconnected, the 
build was interrupted without removing temporary files. On some workers, we got 
around 20 GB of temporary files in /tmp: "cc" files and "tmp" files. I 
guess that some files are coming from the compiler, some other from the Python 
test suite.

I updated the buildbot client configuration of the 9 workers operated by Red 
Hat:

Fedora Rawhide x64-86
Fedora Stable x64-86
RHEL8 x64-86
RHEL7 x64-86
RHEL8 FIPS x86-64
Fedora Rawhide AArch64
Fedora Stable AArch64
RHEL 8 ppc64le
RHEL 7 ppc64le

On our owners, I used the following commands:

systemctl stop buildbot-worker.service
du -sh /tmp; rm -f /tmp/{cc,tmp}*; du -sh /tmp
sed -i -e "s/buildmaster_host = 'buildbot.python.org'/buildmaster_host = 
'buildbot-api.python.org'/;s/keepalive = .*/keepalive = 60/" 
/home/buildbot/buildarea/buildbot.tac; grep -E '(host|keepalive) =' 
/home/buildbot/buildarea/buildbot.tac
systemctl start buildbot-worker.service
systemctl status buildbot-worker.service

[issue41691] Idle 3.8.5 on Win64 won't save a file if it didn't include a newline when it was opened (ex: opening empty file)

[E. Paine]

E. Paine  added the comment:

Thank you for reporting this bug (particularly for the detailed instructions 
for reproduction). This has already been fixed in #41373 just over a month ago, 
and is already available in the 3.9 release candidate (though the fix will not 
be released for 3.8 until 3.8.6).

[issue41686] C++ Embedded 'time.sleep()' is not working on Windows host due to 'Py_InitializeEx(0)'

[Eryk Sun]

Eryk Sun  added the comment:

> Maybe in the time module?

The SIGINT event is also needed by PyOS_Readline, _io (builtin), _winapi 
(builtin), and _multiprocessing (pyd). Is the time module guaranteed to be 
imported in 3.x? It appears to get imported incidentally via _PyImportZip_Init 
(zipimport). 

Could sigint_event be relocated to a platform-dependent extension of 
_PyRuntimeState that gets initialized and finalized independent of any module?

[STINNER Victor]

STINNER Victor  added the comment:

> I can provide some information from the logs of one of the buildbots, or 
> change a parameter. Let me know.

David: can you please change the buildbot client configuration to use 
"buildbot-api.python.org" host name? This host name doesn't go through the PSF 
load balancer. It seems like TCP connection issues are coming from the load 
balancer. Also, please reduce the keepalive to 60 seconds (keepalive_interval).

[issue40352] SocketHandler silently drops log messages on re-connect

[Vinay Sajip]

Vinay Sajip  added the comment:

> It is enough to reopen the socket and send the current message again.

A common reason for connection failure in SocketHandler is the other end going 
offline for some reason. The offline period can often be measured in seconds to 
hours, or even longer. The current strategy is to retry connection, but on the 
next logging call, and with an exponential backoff.

Otherwise, if the remote end goes down and you keep retrying to connect on the 
same call, the handler would keep trying to connect and failing, and this could 
slow things down.

[issue41691] Idle 3.8.5 on Win64 won't save a file if it didn't include a newline when it was opened (ex: opening empty file)

[David Crespo]

New submission from David Crespo :

Idle won't save a file if it didn't include a newline when it was opened (ex: 
opening empty file)

Steps for reproducing the error:
1) get into some folder in Windows File Explorer
2) right-click on empty space for context menu
3) click new -> create text file
4) rename to test.py
5) right click on test.py for context menu
6) click Edit with Idle -> Edit with Idle 3.8 64-bit
7) write some code, ex: print('hello, world!)
8) try to save the file with CTRL+S, or menu file->save, file->save as or 
file->save a copy

IDLE will silently refuse to save the file, the 'not saved' asterisk will 
remain next to the file name and no file is written.

I am using a workaround for this since creating empty files and editing them is 
part of my usual workflow.

If I edit the file with another text editor, save it, and then open it from the 
context menu, it can be saved after editing, but ONLY if i put a newline in the 
file from the alternate text editor. If my the file does NOT contain any 
newline at opening time, IDLE refuses to save it.

This error (refusing to save) seems to happen also when opening from menu 
file->open any file which does NOT contain any newline.

Regards.

[issue41690] Use a loop to collect args in the parser instead of recursion

[Pablo Galindo Salgado]

New submission from Pablo Galindo Salgado :

This program can segfault the parser by stackoverflow:

import ast

code = "f(" + ",".join(['a' for _ in range(10)]) + ")"
print("Ready!")
ast.parse(code)

the reason is that the rule for arguments has a simple recursion when 
collecting args:

args[expr_ty]:
[...]
| a=named_expression b=[',' c=args { c }] {
[...] }

Check https://github.com/we-like-parsers/pegen/issues/245 for more context and

[issue41686] C++ Embedded 'time.sleep()' is not working on Windows host due to 'Py_InitializeEx(0)'

[STINNER Victor]

STINNER Victor  added the comment:

Py_InitializeEx() should be modified to always initialize sigint_event, even if 
install_sigs is equal to zero.

Maybe the variable should be moved somewhere else. Maybe in the time module?

[issue40352] SocketHandler silently drops log messages on re-connect

Serhiy Storchaka  added the comment:

In this particular case we do not need a buffer. It is enough to reopen the 
socket and send the current message again.
