[issue39498] Signpost security considerations in library

[Christian Heimes]

Christian Heimes  added the comment:

There are more features that should have security considerations, e.g. builtin 
functions like eval and exec.

[issue36098] asyncio: ssl client-server with "slow" read

[Christian Heimes]

Christian Heimes  added the comment:

The additional read may read the TLS shutdown alert from the wire. The TLS 
record layer can send additional messages besides application layer data, e.g. 
for post handshake authentication, sessions, rekeying, and to indicate that one 
side is shutting down the current TLS connection.

To investigate you can either use the undocumented SSLContext._msg_callback 
debug hook or Wireshark with SSLKEYLOGFILE env var (available since 3.8).

[issue41110] 2to3 reports some files as both not changing and having been modified

[Ashley Whetter]

New submission from Ashley Whetter :

Many of the fixers cause the tool to report a file as both unchanged and 
modified.

For example when checking a file with the following contents:

```
s = "str"
```

using the following command: `python -m lib2to3 -f unicode unicode_test.py`
The following is output:

```
RefactoringTool: No changes to unicode_test.py
RefactoringTool: Files that need to be modified:
RefactoringTool: unicode_test.py
```

When a fixer returns a node, even if it is the original node without changes, 
it is considered as a change to the code 
(https://github.com/python/cpython/blob/cf18c9e9d4d44f6671a3fe6011bb53d8ee9bd92b/Lib/lib2to3/refactor.py#L446-L447)
 and the file is later added to the list of modified files. I have not yet 
identified which fixers have this issue.

The fix appears to be that fixers need to be aware of when they have not made a 
change and should `None` when that is the case.

[issue41109] subclasses of pathlib.PurePosixPath never call __init__ or __new__

[Étienne Pot]

New submission from Étienne Pot :

I have a subclass GithubPath of PurePosixPath.

```
class GithubPath(pathlib.PurePosixPath):

  def __new__(cls, *args, **kwargs):
print('New')
return super().__new__(cls, *args, **kwargs)

  def __init__(self, *args, **kwargs):
print('Init')
super().__init__()
```

Calling `child.parent` create a new GithubPath but without ever calling __new__ 
nor __init__. So my subclass is never notified it is created.

```
p = GithubPath()  # Print "New", "Init"

p.parent  # Create a new GithubPath but bypass the constructors
```

The reason seems to be that parent calls _from_parts which create a new object 
through `object.__new__(cls)`: 
https://github.com/python/cpython/blob/cf18c9e9d4d44f6671a3fe6011bb53d8ee9bd92b/Lib/pathlib.py#L689


A hack is to subclass `_init` but it seems hacky as it relies on internal 
implementation detail.

[issue40204] Docs build error with Sphinx 3.0 due to invalid C declaration

[Stefan Krah]

Stefan Krah  added the comment:

"""
* Doc/c-api/buffer.rst: the table with ".. c:macro:: PyBUF_INDIRECT" is wrong. 
Sphinx fails because PyBUF_SIMPLE is declared twice.
  => use ":c:macro:`PyBUF_INDIRECT`" instead
"""

Hmm, grep shows:

c-api/buffer.rst:123:  most cases such a request will be 
:c:macro:`PyBUF_SIMPLE` or :c:macro:`PyBUF_WRITABLE`.
c-api/buffer.rst:144:  If :c:member:`~Py_buffer.shape` is ``NULL`` as a 
result of a :c:macro:`PyBUF_SIMPLE`
c-api/buffer.rst:255:Since :c:macro:`PyBUF_SIMPLE` is defined as 0, 
:c:macro:`PyBUF_WRITABLE`
c-api/buffer.rst:258::c:macro:`PyBUF_FORMAT` can be \|'d to any of the flags 
except :c:macro:`PyBUF_SIMPLE`.
c-api/buffer.rst:280:| .. c:macro:: PyBUF_SIMPLE   |  NULL |   NULL  |NULL  
  |



So I see a single definition ans several references. Whether the definition may 
occur in a table is more a question for Georg. :)

It worked up to now and is quite useful, because you can jump directly into the 
correct row.


Escaping the "\*" was necessary at the time for vim syntax highlighting. I 
think it is no longer needed.  So everything has a reason :)

as an FYI I've reproduced this with the httpx library as well: 
https://repl.it/repls/PristineBonyBugs#main.py.  It reproduces on this site but 
I've been unable to reproduce it locally.  It does always reproduce on our 
production systems.

what's interesting is that it I can't seem to be able to reproduce it with 
aiohttp either on that site or locally:
https://repl.it/@thehesiod/PristineBonyBugs-1#main.py

does aiohttp do something to avoid this scenario?

[issue41108] IN module removed in python 3.x; socket doesn't fill in the gap with IP_PORTRANGE*

[Enji Cooper]

New submission from Enji Cooper :

The group that I work with uses the IN.py module to access constants available 
in netinet/in.h on BSD when adjusting socket port ranges.

This compile-time module was never ported forward to 3.x and equivalent 
functionality doesn't exist in the `socket` module. This bug will address that 
issue.

[issue41106] os.scandir() Windows bug dir_entry.stat() not works on file during writing.

[Eryk Sun]

Eryk Sun  added the comment:

In FSBO [1] section 6 "Time Stamps", note that the LastWriteTime value gets 
updated when an IRP_MJ_FLUSH_BUFFERS is processed. In the Windows API, this is 
a FlushFileBuffers [2] call. In the C runtime, it's a _commit [3] call, which 
is an os.fsync [4] call in Python. Calling the latter will update the directory 
entry for the file. 

For an example implementation in the FAT32 filesystem, see 
FatCommonFlushBuffers [5]. Note in the UserFileOpen case that it flushes any 
cached data via FatFlushFile and then updates the directory entry from the file 
control block (FCB) via FatUpdateDirentFromFcb, and finally it  flushes the 
parent directory control blocks (DCBs) -- and possibly also the volume.

Example with os.fsync:

import os
import time
import datetime

UPDATE_DIR = True

FILEPATH = 'C:/Temp/test/spam.txt'

def scan(filepath):
dir_path, filename = os.path.split(filepath)
with os.scandir(dir_path) as iter_dir:
for entry in iter_dir:
if entry.name == filename:
return entry

with open(FILEPATH, 'w') as f:
while True:
print('spam', file=f, flush=True)
if UPDATE_DIR:
os.fsync(f.fileno())
entry = scan(FILEPATH)
stat_result = entry.stat()
now = datetime.datetime.now()
print(f'st_mtime: {stat_result.st_mtime:0.3f}, '
  f'delta_t: {now.timestamp() - stat_result.st_mtime:0.3f}')
time.sleep(1.0)

[issue40986] Async generators are not garbage collected

[Vytautas Liuolia]

Vytautas Liuolia  added the comment:

I've now skimmed through the relevant Trio issue 
https://github.com/python-trio/trio/issues/265 and the currently deferred 
https://www.python.org/dev/peps/pep-0533/ and, as I understand, the issue is 
not trivial and subject to subtle edge cases.

Getting back to the issue, it looks like a misunderstanding on my side, sorry!

As per PEP-525:

The asyncio event loop will use sys.set_asyncgen_hooks() API to maintain a 
weak set of all scheduled asynchronous generators, and to schedule their 
aclose() coroutine methods when it is time for generators to be GCed.

It seems that my original test case just doesn't give these aclose() coroutines 
a chance to run. Awaiting an asyncio.sleep() "fixes" that.

[issue41107] Running a generator in a map-like manner

[Natsumi H.]

New submission from Natsumi H. :

I suggest adding a function which behaves like map but without returning 
anything to iterate over a generator.

This is useful in cases where you need to run a function on every element in a 
list without unnecessarily creating a generator object like map would. 

I think given the existence of the map function that this should be added to 
Python.

[issue41106] os.scandir() Windows bug dir_entry.stat() not works on file during writing.

[Steve Dower]

Steve Dower  added the comment:

I'm going to have to spend more time to analyse this (later), but it seems like 
Windows deciding not to update the directory's data structures (containing the 
st_mtime retrieved by scandir) as long as the file is still open.

I suspect the answer for your scenario is that you'll just have to use 
os.stat() to get the information from the file's entry, rather than the 
directory's entry. It's unlikely there's anything we can do at Python's level 
without sacrificing all the performance gains of scandir() for all other 
scenarios.

Georg Brandl  added the comment:

Don't hesitate to send requests back to the Sphinx tracker if any changes 
appear to be too restrictive to you. It is a documentation tool, not a compiler.

[issue41096] Need command to exit PDB interactive shell

[Kerrick Staley]

Kerrick Staley  added the comment:

Serhiy: I'm referring to the interactive mode that can be entered by typing 
"interact" in PDB.

Here are reproduction instructions:
1. Run "python3" command.
2. In Python shell, type "import pdb; pdb.set_trace()".
3. In PDB shell, type "interact".

Now, in this "PDB InteractiveConsole" shell (I'm not sure what it's called), 
the only way to go back to PDB is to press Ctrl+D. If you type "quit()" or 
"exit()" it exits the entire Python process. If you type "q" it says 
"NameError: name 'q' is not defined".

In Jupyter, I get different (but still undesirable) behavior: "quit()" raises 
"NameError: name 'quit' is not defined" (and similar for "exit()").

I think "quit()"/"exit()" in these contexts should return you back to the PDB 
shell.

[issue41106] os.scandir() Windows bug dir_entry.stat() not works on file during writing.

[Cezary Wagner]

Cezary Wagner  added the comment:

One hint more.

Start of new process os.scandir() give invalid modification date for file open 
for writing until external tool is not called (like explorer, touch, etc.).

So (log open for writing and write is done between 1, 2):
1. Run program with os.scandir() -> dir_entry.stat().st_mtime() = t1.
2. Run program with os.scandir() -> dir_entry.stat().st_mtime() = t1.
Modification is stalled.

Another scenario (log open for writing and write is done between 1, 3):
1. Run program with os.scandir() -> dir_entry.stat().st_mtime() = t1.
2. touch -> dir_entry.path
3. Run program with os.scandir() -> dir_entry.stat().st_mtime() = t2.
Modification works.

Extra file for for tests with:

[issue41106] os.scandir() Windows bug dir_entry.stat() not works on file during writing.

[Cezary Wagner]

New submission from Cezary Wagner :

I have problem with change detection of log during writing under Windows 
(normal fs and windows share). Probably bad order of Windows API calls - no 
idea.

Test program is attached. You can reproduce it. Try with os.scandir() without 
os.stats() and os.stat().

Source code responsible for it is probably this -> I do not understand CPython 
code -> https://github.com/python/cpython/blob/master/Modules/posixmodule.c.

Here is full description - many test was done.

# os.scandir() Windows bug dir_entry.stat() not works on file during writing.
# Such files is for example application log.
# No problem with os.stat()

# Call of os.stat() before os.scandir() -> dir_entry.stat() is workaround.
# Open file during writing other program "fixes" dir_entry.stat().
# Get properties on open file during writing "fixes" dir_entry.stat().

# Notice that I run os.scandir() separately so dir_entry.stat() is not cached.

# Steps to reproduce lack of modification update:
# 1. Close all explorers or other application using PATH (it has impact).
# 2. Set PATH to test folder can be directory or windows share.
# 3. Run program without DO_STAT (False).
#
# Alternative steps (external app force valid modification date):
# 4. run 'touch' or 'echo' on file should "fix" problem. 'echo' will throw 
error not matter.
#
# Alternative scenario (os.stat() force valid modification date - very slow):
# 3. Run program without DO_STAT (True). No problems.
#
# Error result:
# Modification date from dir_entry.stat() is stalled (not changing after 
modification)
# if os.stat() or other Windows application not read file.
#
# Excepted result:
# Modification date from dir_entry.stat() is update from separate calls 
os.scandir()
# or cached if it is same os.scandir() call.
#
# Notice that os.scandir() must be call before dir_entry.stat() to avoid 
caching as described in documentation.
# And this is done but not work on files during writing..
#
# Ask question if you have since is very hard to find bug.

[issue40204] Docs build error with Sphinx 3.0 due to invalid C declaration

[STINNER Victor]

STINNER Victor  added the comment:

I look into this issue. It's quite complicated :-(

The Sphinx 3.0.0b1 changelog says:

* The C domain has been rewritten, with additional directives and roles. The 
existing ones are now more strict, resulting in new warnings.
* The C domain has been rewritten adding for example:

  * Cross-referencing respecting the current scope.
  * Possible to document anonymous entities.
  * More specific directives and roles for each type of entitiy, e.g., handling 
scoping of enumerators.
  * New role c:expr for rendering expressions and types in text.

The Python documentation has many issues:

* Doc/howto/instrumentation.rst: ".. c:function:: function__entry(str filename, 
str funcname, int lineno)" is not valid
  => replace "str" with "char*" and explain that "char*" must be read as 
"str"... The documentation is about DTrace functions, it's not C code.

* Doc/library/configparser.rst: "unique" is declared twice
  => the second declaration must have :noindex: marker

* ".. c:function:: PyObject* PyObject_CallMethodObjArgs(PyObject *obj, PyObject 
*name, ..., NULL)": the "..., NULL" part is invalid in C => remove ", NULL"

* .. c:var:: PY_VECTORCALL_ARGUMENTS_OFFSET: a variable must be declared with 
its type, but PY_VECTORCALL_ARGUMENTS_OFFSET is macro
  => use ".. c:macro::" instead

* ".. c:var:: Py_BytesWarningFlag": the type is missing
  => ".. c:var:: int Py_BytesWarningFlag"

* Doc/c-api/call.rst: vectorcallfunc documentation is not properly indented.
  => fix indentation

* Doc/c-api/buffer.rst: the table with ".. c:macro:: PyBUF_INDIRECT" is wrong. 
Sphinx fails because PyBUF_SIMPLE is declared twice.
  => use ":c:macro:`PyBUF_INDIRECT`" instead

* :c:type:`PyObject\*` is invalid
  => use  :c:type:`PyObject*`

* ... there are many other errors :-(

PR 19397 fix some errors, but not all of them.

[issue41105] Add some extra content check for some who has been deprecated by glibc

[Manjusaka]

New submission from Manjusaka :

Hello everyone

When I try to compile the code from the master branch on my Manjaro, one of the 
Linux system based on the Arch and based on the glibc-2.31 && gcc-10.1.0 . the 
compiler show me that the fcntl module has been failed to be compiled

Here's the message 

/home/manjusaka/Documents/project/cpython/Modules/fcntlmodule.c:618:33: error: 
‘I_PUSH’ undeclared (first use in this function)

I have figured out the reason because the stropts.h has been deprecated since 
the glic-2.30, but some of the distribution of Linux keep an empty file on the 
/usr/include, so the configure process will recognize stropts.h is existed and 
open HAVE_STROPTS_H flag.

So should we add an extra content check in the configure process to avoid the 
empty file problem?

[issue40512] [subinterpreters] Meta issue: per-interpreter GIL

[STINNER Victor]

STINNER Victor  added the comment:

Update of the EXPERIMENTAL_ISOLATED_SUBINTERPRETERS status.

I made many free lists and singletons per interpreter in bpo-40521.

TODO:

* _PyUnicode_FromId() and interned strings are still shared: typeobject.c 
requires a workaround for that.
* GC is disabled in subinterpreters since some objects are still shared
* Type method cache is shared.
* pymalloc is shared.
* The GIL is shared.

I'm investigating performance of my _PyUnicode_FromId() PR: 
https://github.com/python/cpython/pull/20058

This PR now uses "atomic functions" proposed in a second PR: 
https://github.com/python/cpython/pull/20766

The "atomic functions" avoids the need to have to declare a variable or a 
structure member as atomic, which would cause different issues if they are 
declared in Python public headers (which is the case for _Py_Identifier used by 
_PyUnicode_FromId()).

[issue41104] IMAPlib debug errors

This line in imaplib.py inside _dump_ur function:
l = map(lambda x:'%s: "%s"' % (x[0], x[1][0] and '" "'.join(x[1]) or ''), l)

fails because the untagged responses are bytestrings and it expects regular 
strings.

[issue41102] ZipFile.namelist() does not match the actual files in .zip file

[Xiaolong Liu]

New submission from Xiaolong Liu :

I used zipfile module to archive thousands of .geojson file to zip files and 
access those .geojson file by ZipFile.open() method. In my hundreds of 
runnings, one of them was abnormal.
As the title says, the ZipFile.namelist() did not match all the files in .zip 
file. And I extracted it by extractall() method and it only got those files 
included in the namelist. On the other hand, I extracted it by my compress 
software (360zip). I got the other files unincluded in the namelist(). Only one 
file (2564.geojson) appeared with these two extract methods.
ZipFile.extractall() method got 674 files from '2654.geojson' to '3989.geojson'.
360zip got 1399 files from '.geojson' to '2654.geojson'.
The abnormal file is too big to upload this page and I uploaded to google drive:

[issue41101] Support "arm64" in Mac/Tools/pythonw

[Ronald Oussoren]

New submission from Ronald Oussoren :

Apple introduced a new CPU architecture for macOS at WWDC, which is arm64.

Mac/Tools/pythonw.c launches the real python interpreter in a framework build 
is and is careful to launch that using the same architecture as it is running 
(to make it possible to use "arch -x86_64 pythonw" to launch the x86_64 variant 
when available.

The current code does not support ARM64.

[issue41099] Deprecating PyUnicodeTranslateError_Create

[Inada Naoki]

New submission from Inada Naoki :

PyUnicodeTranslateError_Create marked as Py_DEPRECATED since it receives  
Py_UNICODE* as an argument.
But it is not deprecated in the document.

On the other hand, we have alternative private API which accepts Unicode 
object: _PyUnicodeTranslateError_Create.  Should we make it public?

Otherwise, we can recommend `PyObject_CallFunction(PyExc_UnicodeTranslateError, 
...)` as an alternative.

[Inada Naoki]

New submission from Inada Naoki :

PyUnicodeEncodeError_Create is using Py_UNICODE and is marked 
Py_DEPRECATED(3.3).
But it is not deprecated in doc yet.

There are no alternative API.  In CPython code base, UnicodeEncodeError is 
created by `PyObject_CallFunction(PyExc_UnicodeEncodeError, ...)`.

Can we just document it as deprecated since Python 3.3?
Or should we add alternative API?

[Ned Deily]

Ned Deily  added the comment:

@Serhiy, you have opened PRs for this for 3.7 and 3.6, both of which are now in 
the security-fix phase of their release cycles. It looks like this behavior has 
been around for a long time and does not appear to be a security issue. Unless 
there is some important reason why this behavior should be changed in a 
security fix release (for 3.6) or as a release critical fix for 3.7.8 final and 
unless another core developer reviews the changes, I do not think the PRs 
should be merged to 3.7 or 3.6.
