[issue34229] Possible access to unintended variable in "cpython/Objects/sliceobject.c" line 116

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Is there a way to test this or trigger this code using Python syntax? 

`slice(start, stop, step).indices()` uses slice_indices in 
Objects/sliceobject.c . I checked the function docs 
https://docs.python.org/2.7/c-api/slice.html#c.PySlice_GetIndices and it states 
below

> You probably do not want to use this function. If you want to use slice 
> objects in versions of Python prior to 2.3, you would probably do well to

> source of your extension.

I couldn't see it's usage too anywhere and with Python 3 we have all integers 
are implemented as “long” integer objects of arbitrary size and can see only 
PyLong_Check at 
https://github.com/python/cpython/blob/master/Objects/sliceobject.c#L178

Thanks

You need to expose it in the _testcapi module as Python function.

I don't think that it's worth it to backport this change. It's really a corner

[issue34232] Python3.7.0 exe installers (32 and 64 bit) failing on Windows7

[Wolfgang Maier]

New submission from Wolfgang Maier :

System: Windows7 Enterprise SP1 64-bit
Downloaded the executable installer from python.org (tried both 32- and 64-bit 
-> same error)

Selected the default user-install and got an almost immediate Error message: 
The TARGETDIR variable must be provided when invoking this installer.

Clicking OK reveals 0x80070643 - Fatal error during installation and the 
attached log file.

Rebooting didn't help and I also tried playing with custom installation 
settings, too, but no success so far.

#define _PyAnyInt_CheckExact(op) (PyInt_CheckExact(op) || PyLong_CheckExact(op))

[issue34233] subprocess.check_output goes to infinte loop

[Eryk Sun]

Eryk Sun  added the comment:

`cmd.exe dir` ignores the unrecognized `dir` argument and runs the interactive 
shell. The shell is waiting for input on stdin. You can type "exit" and press 
enter to return to Python.  

When you run this from IDLE (i.e. via pythonw.exe), there's no StandardInput 
handle to inherit, so subprocess executes cmd.exe with its stdin set to a 
closed pipe. (I don't know why a closed pipe is used. I think "NUL" would be 
better.) The shell exits immediately because ReadFile fails with 
ERROR_BROKEN_PIPE.

[issue34235] PyArg_ParseTupleAndKeywords: support required keyword arguments

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

In Python the function can have 4 kinds of parameters:

def f(a, b=1, *, c, d=2):

1. a is a required positional-or-keyword parameter.
2. b is an optional positional-or-keyword parameter.
3. c is a required keyword-only parameter.
4. d is an optional keyword-only parameter.

But PyArg_ParseTupleAndKeywords() supports only 3 of them. Keyword-only 
parameters can only be optional.

PyArg_ParseTupleAndKeywords(args, kwds, "O|O$O", kwlist, &a, &b, &d)

This makes impossible using PyArg_ParseTupleAndKeywords() for haslib.scrypt(). 
Currently it parses all keyword-only arguments as optional, and checks that 
they are specified specially, but this does not allow to use the full power of 
the PyArg_Parse* API.

New submission from Anton Patrushev :

The issue is invalid. I just added the following lines to the end of your main:
```
line = await asyncio.wait_for(process.stderr.readline(), 10)
print(line)
```

and got additional info:
```
b'/bin/bash: echo local: command not found\n'
```

So the problem is not in asyncio.

[issue34236] Test6012 in test_capi is not run as part of make test

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan :

Test6012 is not run as part of make test since it's not added to 
support.run_unittest at the end of the file. Hence running the test as a single 
file causes error. It seems argparsing related test which is a part of 
_testcapi.module.c in Python 3 branch was not cleanly backported and I tried 
backporting it but it requires PyUnicode_FSConverter which I think is Python 3 
only. Since the test was not running during make test there was no error about 
this during backporting during merge.

Relevant backport commit : ef19fd200d0768919f1658466f8b6080b191fba0

[issue33089] Add multi-dimensional Euclidean distance function to the math module

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I don't want to make any guarantees beyond what the doc patch says.

Commutativity guarantees are difficult to deliver without exact summation. A 
switchover to C's hypot() creates an external dependency such that we can't 
make any more guarantees than were given to us (which is nothing).  Also, 
algorithmic switchovers risk impairing monotonicity.  The Inf/NaN rules already 
existed before this patch and I believe that Mark elected to not document them 
on a function by function basis.  Another reason not to make guarantees is that 
this is a "mostly good-enough patch" and I expect that either Mark or Tim will 
someday improve it with a "single-rounding dot product".  My aim is to make it 
good before any effort is given to making it perfect.  In the meantime, it 
makes little sense to guarantee implementation details.

[issue33089] Add multi-dimensional Euclidean distance function to the math module

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Commutativity guarantees can be delivered by sorting arguments before 
summation. In any case the sorting is needed for more accurate summation (from 
smaller to larger).

[issue19891] Exiting Python REPL prompt with user without home directory throws error in atexit._run_exitfuncs

[Anthony Sottile]

Anthony Sottile  added the comment:

I was able to reproduce both the `PermissionError` and the `FileNotFoundError` 
under these circumstances:

$ docker run --user 123:123 -ti python python
Python 3.7.0 (default, Jul 17 2018, 11:04:33) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
Error in atexit._run_exitfuncs:
PermissionError: [Errno 13] Permission denied


$ docker run --user nobody -ti python python
Python 3.7.0 (default, Jul 17 2018, 11:04:33) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
Error in atexit._run_exitfuncs:
FileNotFoundError: [Errno 2] No such file or directory


In the former, the home directory is `/` (not writable).  In the latter, the 
homedir is `/nonexistent`, which, well, doesn't exist.

My patch addresses both of these errors.

[issue34238] When BROWSER is set on Mac webbrowser.register_standard_browsers doesn't work

[Jason]

New submission from Jason :

Description: When BROWSER is set, webbrowser.get fails because 
register_standard_browsers throws an error.

Work around: You can still use `webbroswer._browsers[key][1].open(url)` to open 
a browser. 


Operating system: macOS High Sierra v10.13.6


Reproduction 1:

```

[issue34239] Convert test_bz2 to use tempfile

[Tim Golden]

New submission from Tim Golden :

test_bz2 currently uses the test.support.TESTFN functionality which creates a 
temporary file local to the test directory named around the pid. 

This can give rise to race conditions where tests are competing with each other

[issue34238] When BROWSER is set on Mac webbrowser.register_standard_browsers doesn't work

[Jason]

Jason  added the comment:

Serhiy, I believe you are correct. I updated my local python and it passed.

However, I think there might be a bug with the implementation that doesn't
correctly respect the BROWSER preference. If I do:

```
➜  BROWSER=lynx python3

Python 3.7.0 (default, Jul 23 2018, 20:22:55)
[Clang 9.1.0 (clang-902.0.39.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import webbrowser
>>> webbrowser.register_standard_browsers()
>>> webbrowser._tryorder
['MacOSX', 'chrome', 'firefox', 'safari', 'lynx', 'lynx']
>>> webbrowser._browsers
{'macosx': [None, ],
'chrome': [None, ],
'firefox': [None, ],
'safari': [None, ],
'lynx': [None, ]}
```
Notice how the webbrowser._tryorder has two 'lynx' items and both of them
are last. If you look at the comment in the code, it says that it should be
prepended to _tryorder because it's the preferred browser. See
https://github.com/python/cpython/blob/56b29b6d6fa3eb32bb1533ee3f21b1e7135648a0/Lib/webbrowser.py#L563

If I change `cmd = _synthesize(cmdline, preferred=False)`, line 566, to
preferred=True then the output is like this:

```
>>> webbrowser._tryorder
['lynx', 'MacOSX', 'chrome', 'firefox', 'safari', 'lynx']
```

Which I believe is closer to being correct based upon the comments in the
code.

Am I wrong about this, and should I open up a new bug report for it?

Thanks.

[issue34242] configparser: SectionProxy.get is silent on missing options

[Stig Johan Berggren]

New submission from Stig Johan Berggren :

`get()` on a ConfigParser object behaves differently from `get()` on a section. 
The former raises an exception when the key does not exist and no fallback has 
been explicitly set. The latter returns None, with no option to raise an error 
for missing keys. I think this is confusing, and that both classes should have 
the same behaviour. I prefer raising an error, as it makes it easier to find 
errors such as typos in config files.

In addition, the docs state that the "parser-level `get` method
provides a custom, more complex interface, maintained for backwards
compatibility". The SectionProxy `get` method internally uses the parser-level 
`get`, so it seems unlikely that it is only maintained for backwards 
compatibility.

My proposed change is not backwards compatible, as any code that relies on a 
None being returned when a key does not exist would have to make this explicit 
through the fallback argument in `get`.

Here is the current behaviour in the latest build (3.8.0a0):

>>> import configparser
>>> c = configparser.ConfigParser()
>>> c.add_section('spam')
>>> c['spam'].get('eggs') # Returns None
>>> c['spam']['eggs']
Traceback (most recent call last):
  ...
KeyError: 'eggs'
>>> c.get('spam', 'eggs')
Traceback (most recent call last):
  ...
configparser.NoOptionError: No option 'eggs' in section: 'spam'
>>>

[issue34243] pty.spawn: inconsistent interface

[zerx]

New submission from zerx :

# spawn(argv, master_read=_read, stdin_read=_read)

With stdin_read function it's possible to customize how one can read from 
stdin, but it makes little sense without stdout counterpart. For example, you 
cannot use a wrapped ssl socket to forward a terminal over secure connection, 
because os.write(STDOUT_FILENO, data) is not suitable for ssl sockets.

The proposal is to add stdout_write argument.

[issue33129] Add kwarg-only option to dataclass

[Jimbo Jim]

Jimbo Jim  added the comment:

first post in bugs.python.org... are people normally scary around here?

Another usecase of keyword-only arguments is that I can mix default and 
non-default fields in any order. This could be achieved by either marking all 
fields as read-only, or by implicitly adding an asterisk before the first 
"conflicting" non-default argument (or by translating .../etc into an asterisk).

(Is it a bad idea to create a private fork of `pip install dataclasses` with 
implicit asterisk, purely for my own project?)

[issue34240] Convert test_mmap to use tempfile

[Eryk Sun]

Eryk Sun  added the comment:

To clarify, TEMPDIR in this case is from the following code in 
Lib/test/libregrtest/main.py:

# When tests are run from the Python build directory, it is best practice
# to keep the test files in a subfolder.  This eases the cleanup of leftover
# files using the "make distclean" command.
if sysconfig.is_python_build():
TEMPDIR = sysconfig.get_config_var('abs_builddir')
if TEMPDIR is None:
# bpo-30284: On Windows, only srcdir is available. Using 
abs_builddir
# mostly matters on UNIX when building Python out of the source 
tree,
# especially when the source tree is read only.
TEMPDIR = sysconfig.get_config_var('srcdir')
TEMPDIR = os.path.join(TEMPDIR, 'build')
else:
TEMPDIR = tempfile.gettempdir()
TEMPDIR = os.path.abspath(TEMPDIR)

Then in class Regrtest we have:

def main(self, tests=None, **kwargs):
global TEMPDIR

if sysconfig.is_python_build():
try:
os.mkdir(TEMPDIR)
except FileExistsError:
pass

# Define a writable temp dir that will be used as cwd while running
# the tests. The name of the dir includes the pid to allow parallel
# testing (see the -j option).
test_cwd = 'test_python_{}'.format(os.getpid())
test_cwd = os.path.join(TEMPDIR, test_cwd)

# Run the tests in a context manager that temporarily changes the CWD 
to a
# temporary and writable directory.  If it's not possible to create or
# change the CWD, the original CWD will be used.  The original CWD is
# available from support.SAVEDCWD.
with support.temp_cwd(test_cwd, quiet=True):

[issue28909] Adding LTTng-UST tracing support

[Peter McCormick]

Peter McCormick  added the comment:

I would like to propose the following patch[0] which generalizes the 
`PyDTrace_*` definitions to a more generic `PyProbe` structure, in anticipation 
of including LTTng support side-by-side with the existing DTrace support.

A couple of argument types in `Include/pydtrace.h` were also changed to match 
those in `Include/pydtrace.d`. I can split that out to a separate, pre-PyProbe 
patch if that would be preferred.

Some of the `*_ENABLED()` calls were reorganized such that they will actually 
be invoked twice (specifically in `Python/ceval.c` were the enabled check was 
used prior to calling helper functions, which then eventually invoked the 
DTrace macros.) If this won't work, we could add a sequence of 
guarded-by-ifdef-instead-of-enabled calls to ensure that there will only ever 
be one instance of any given `PyDTrace_*_ENABLED()` call.

I've tested compilation on macOS with and without DTrace configured.

Feedback and comments would be most welcome!

Thanks,
Peter
