[issue34245] Python library should be installed writable

[Jeroen Demeyer]

New submission from Jeroen Demeyer :

In Makefile.pre.in, there is this:

# Shared libraries must be installed with executable mode on some systems;
# rather than figuring out exactly which, we always give them executable mode.
# Also, making them read-only seems to be a good idea...
INSTALL_SHARED= ${INSTALL} -m 555

Installing libraries read-only is very non-standard (I'm not aware of any other 
build system which does that). Python should just use the more standard 755 
install mode.

[issue27717] sqlite documentation bug

[Berker Peksag]

Berker Peksag  added the comment:

Looking at this again, I think the current version of the documentation should 
stay as-is. Perhaps my patch can make the insecure example separated from the 
secure one, but I don't think it's worth to apply it.

[issue34240] Convert test_mmap to use tempfile

[Tim Golden]

Tim Golden  added the comment:

Thanks for the information, eryksun.

For the moment, I can only say with a fair degree of certainty that using the 
tempfile functions as I have in test_bz2 & test_mmap appears to solve the issue 
which is repeatably if intermittently present without that change.

I'll be trying to narrow the issue down before making any further changes

[issue34221] Any plans to combine collections.OrderedDict with dict

[Philip Lee]

Philip Lee  added the comment:

What about my last suggestion :
it would be better to move "Dictionaries preserve insertion order" part at the 
end of the doc of https://docs.python.org/3/library/stdtypes.html#dict up below 
the doc for 
class dict(**kwarg)
class dict(mapping, **kwarg)
class dict(iterable, **kwarg)
so that people won't miss the feature when consulting the doc.

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

[INADA Naoki]

INADA Naoki  added the comment:

I don't think it's worth enough to break backward compatibility.

Additionally, "section.get(key) returns None if key is not exist" is consistent 
with dict's behavior.

On the other hand, "parser.get(section, key)" has different signature from 
dict's get method.  So inconsistency is not a big problem.

[Jeroen Demeyer]

Why would that argument apply to a binary file (and only to binary files)?

> Is there any real world problem about read-only library?

It makes it slightly harder to remove a Python installation. Depending on the 
OS, you'll get a failure or require some additional confirmation.

Furthermore, it's very non-standard. Even if that's not a problem by itself, 
Python should just install things in the standard way.

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

[Stig Johan Berggren]

Stig Johan Berggren  added the comment:

That's fair, I didn't consider consistency with dicts' `get`. Maybe a 
ConfigParser object could have an option to raise errors, because they are 
useful for discovering errors in config files.

I still find the remark about the parser-level `get` being maintained for 
backwards compatibility strange (and it is eight years old), could this be 
improved?

[issue34237] faq/design: PEP 572 adds assignment expressions

[Jonathan Fine]

Jonathan Fine  added the comment:

My mistake. But not mine only.

According to https://www.python.org/dev/peps/pep-0572/ the PEP is 
Python-Version: 3.8

I took this to mean that it had been implemented in Python 3.8. Reading the PEP 
more closely, it also says Status: Accepted.

According to https://www.python.org/dev/peps/pep-0001/#pep-header-preamble each 
PEP can have an optional Python-Version, which is "described below". I thus find
===
Standards Track PEPs will typically have a Python-Version header which 
indicates the version of Python that the feature will be released with.
===

I seems to me that there is a bug in the PEP, perhaps caused either by a 
failure to increment its Python-Version as part of the release of Python 3.8, 
or the PEP itself providing too early the optional Python-Version.

I'll email Chris Angelico about this. I'm very happy for the issue to remain 
closed.

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Ronald Oussoren]

New submission from Ronald Oussoren :

Attached is a very basic launcher for python scripts. This script works as 
expected in Python 3.6, but not in 3.7.0.

In particular, the launcher sets the environment variable PYTHONOPTIMIZE before 
calling Py_Initialize and that setting is ignored.

I haven't tried testing with the tip of the tree yet.

[issue34248] dbm errors should contain file names

[sds]

New submission from sds :

`dbm` errors should contain file names when appropriate, just like `OSError`.
E.g.:
```
>>> open("fo")
Traceback (most recent call last):
  File "", line 1, in 
FileNotFoundError: [Errno 2] No such file or directory: 'fo'
>>> import dbm.gnu
>>> dbm.gnu.open("fo")
Traceback (most recent call last):
  File "", line 1, in 
_gdbm.error: [Errno 2] No such file or directory
```
the `_gdbm.error` should report the file name `'fo'` just like 
`FileNotFoundError` does (and `exn.args` should contain the file name too!)

[issue34237] faq/design: PEP 572 adds assignment expressions

[Jonathan Fine]

Jonathan Fine  added the comment:

First, I'm delighted that the current docs are in fact correct regarding 
assignment expressions. (I should have said this earlier.)

I'm happy to wait for the implementation to land. (And if you like, I'm willing 
to help with the documentation. I seem to have an eye for detail.)

Whether or not mine was the only my mistake, I was misled by the PEP 572 
header. (And perhaps Vadim was also - msg322479.)

This issue is, rightly, closed. Perhaps the discussion should continue in a new 
issue? And without Chris, if he doesn't want to be involved. Perhaps it's a 
matter for the release manager?

Or perhaps having Python-Version:3.8 in the PEP remain until the change lands 
(and then both Status and Python-Version will be changed). 

I'm new here. I'm happy for someone else to decide. No action is one option.

[issue34237] faq/design: PEP 572 adds assignment expressions

[Jonathan Fine]

Jonathan Fine  added the comment:

I'm sorry. I apologise. I'm being a bit stupid. Everything is fine. Nothing to 
do.

In case you care, here's the situation. Python 3.8 is in development, and not 
yet released. Somehow, I'd got it into my mind that it had already been 
released.

So the PEP 572 header is correct. The PEP status is accepted, the feature is in 
development (including documentation), and all being well the feature and the 
documentation will appear in Python3.8.

By the way, according to https://www.python.org/dev/peps/pep-0569/#id5, the 
first alpha is due 2019-01-27.

So please, all of you, accept my apologies.

[issue34249] Full set of format codes applies to strftime only

[v kats]

New submission from v kats :

Section "strftime() and strptime() Behavior" says:

"The full set of format codes supported varies across platforms, because Python 
calls the platform C library’s strftime() function, and platform variations are 
common. To see the full set of format codes supported on your platform, consult 
the strftime(3) documentation."

It implies that this applies for strftime only, and indeed it refers to C 
library’s strftime().

However, it's easy to miss (at least I got confused and lost some time), so I 
propose to clarify the paragraph.

strptime and %s

[issue34250] import xmlrpclib not works in file named "xml.py"

[Fekete György]

New submission from Fekete György :

Big magic in python 2.7.15 win version:

Create file: "xml.py" containing 2 code lines:

import xmlrpclib

proxy = xmlrpclib.ServerProxy("http://localhost:8000/";)

run it, and it gives u a nice error:
C:\work\mitre>\Python27\python.exe xml.py
Traceback (most recent call last):
  File "xml.py", line 1, in 
import xmlrpclib
  File "C:\Python27\lib\xmlrpclib.py", line 538, in 
from xml.parsers import expat
  File "C:\work\mitre\xml.py", line 3, in 
proxy = xmlrpclib.ServerProxy("http://localhost:8000/";)
AttributeError: 'module' object has no attribute 'ServerProxy'


U also get this error, when this file present in the directory where u want to 
import xmlrpclib in another py. ANd if only the compiled xml.pyc exist, the bug 
comes.  But if you rename it to xm.py, it works!

Maybe a bad import from wrong directory in xmlrpclib. Not tested on another 
version or platform.

[issue34251] MSI build fails

[Kay Hayen]

New submission from Kay Hayen :

Hello there,

building an MSI for my project fails. I am calling it like this:

assert subprocess.call(
(
sys.executable,
"setup.py",
"bdist_msi",
"--target-version=" + sys.version[:3]
)
) == 0

Giving the target version is probably non-sense and from a time, where one 
script was building multiple MSIs, I no longer do that.

and it gives:

 File "C:\Python37_64\lib\site-packages\setuptools\__init__.py", line 129, in 
setup
return distutils.core.setup(**attrs)
  File "C:\Python37_64\lib\distutils\core.py", line 148, in setup
dist.run_commands()
  File "C:\Python37_64\lib\distutils\dist.py", line 966, in run_commands
self.run_command(cmd)
  File "C:\Python37_64\lib\distutils\dist.py", line 985, in run_command
cmd_obj.run()
  File "C:\Python37_64\lib\distutils\command\bdist_msi.py", line 256, in run
self.add_find_python()
  File "C:\Python37_64\lib\distutils\command\bdist_msi.py", line 346, in 
add_find_python
if msilib.Win64:
AttributeError: module 'msilib' has no attribute 'Win64'


This happens for 32 and 64 bit CPython 3.7.0 installations. The same code works 
for all of 2.7, 3.3 through to 3.6, so this is a regression.
 
Any idea?

Thanks,
Kay

[issue34252] Bunch of path leaks on Python 3.7 on Release

New submission from Alberto :

I've downloaded and compiled from sources Python 3.7 in windows.
The compilation process goes great but there are a lot of paths (using __FILE__

This is because __FILE__ is used outside of assert or DEBUG ifdefs which should 
be avoided.

[issue34252] Bunch of path leaks on Python 3.7 on Release

[Alberto]

Alberto  added the comment:

In Visual Studio /FP should be removed:
In C/C++ → Advanced → Use Full Paths: No

But still for some weird reason there is one path that gets leaked:
c:\users\mysupersecretuser\downloads\python-3.7.0_\modules\_decimal\libmpdec\typearith.h

In the project from where I'm using python I already removed /FP so even if it 
is a header it should not be showing the full path AFAIK.

Any idea?

[issue34253] Tkinter- On windows, calling filedialog or messagebox before the window is drawn causes focus issues

[Novel]

New submission from Novel :

Code to reproduce the problem: 

```
import tkinter as tk
from tkinter.messagebox import showinfo

root = tk.Tk()
entry = tk.Entry(root)
entry.pack()
# root.update() # remove comment to fix the problem
showinfo('alert', 'this parrot is dead!')
root.mainloop()
```

Running this code will show the alert, and when the user clicks "ok" the entry 
widget acts as if it's disabled and won't focus. Minimizing and restoring the 
tkinter window brings the entry widget back to normal operation. 

Workaround: Calling `update()` before the messagebox or filedialog call gives 
normal behaviour. 

This issue only affects Windows as far as I can tell.

[issue34239] Convert test_bz2 to use tempfile

[Brett Cannon]

Brett Cannon  added the comment:

Should this issue be closed, Tim, after you update for Serhiy's suggestion? 
(Basically I'm just making sure you know issues are not automatically closed 
after merge :) .

[issue2651] Strings passed to KeyError do not round trip

[INADA Naoki]

INADA Naoki  added the comment:

Even if we fixed stdlib, there are many KeyError(missing) idiom used in 3rd 
party code.

KeyError: '42'
KeyError: '42\n'
KeyError: 42

All of the above are looks different.  I think it's good.
Is it really worth enough to break it?

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

This feels like a duplicate of https://bugs.python.org/issue31845 (see 
https://github.com/python/cpython/commit/d7ac06126db86f76ba92cbca4cb702852a321f78
 )

Is this definitely with the 3.7.0 release, or is it potentially with one of the 
earlier alphas before that fix was applied?

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

Ah, wait - I see a relevant difference: the test case for issue31845 uses 
Py_Main, *not* Py_Initialize (since it's a command line test, not an embedding 
test).

That means it's currently possible for the sequence of operations in 
https://github.com/python/cpython/blob/7cbde0e09daba4259565738e48f141851287fe29/Python/pylifecycle.c#L913
 to be wrong (or missing steps) without causing the test suite to fail.

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

Comparing to Python 3.6, we can see that the code to update the C global flags 
from the environment variables used to live directly in 
_PyInitializeEx_Private: 
https://github.com/python/cpython/blob/9d85856044a2c7d681ea38b5ff99af375b228a0f/Python/pylifecycle.c#L305

In Python 3.7 that section 
(https://github.com/python/cpython/blob/3.7/Python/pylifecycle.c#L913 ) 
currently calls _PyCoreConfig_Read instead, which *only* updates the config 
struct - it doesn't update the C level global variables.

By contrast, Py_Main eventually calls 
https://github.com/python/cpython/blob/7cbde0e09daba4259565738e48f141851287fe29/Modules/main.c#L1394
 which handles writing the state from the config struct back to the global 
variables.

Ned, I think we should consider this a release blocker for 3.7.1

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

Next steps:

- add a test case that runs the same sys.flags checks as in 
https://github.com/python/cpython/commit/d7ac06126db86f76ba92cbca4cb702852a321f78,
 but as a test_embed embedding test using Py_Initialize rather than Py_Main
- create a shared internal API that both Py_Main and Py_Initialize can use to 
write the environment variable settings back to the global variables

[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

[Nick Coghlan]

Nick Coghlan  added the comment:

This seems closely related to the work Victor is already pursuing to resolve 
bpo-34170 for Python 3.8 (e.g. 
https://github.com/python/cpython/commit/56b29b6d6fa3eb32bb1533ee3f21b1e7135648a0
 ).

The bpo-34170 changes are more invasive than we'd like for a maintenance 
release, but it would be preferable to keep at least any new Python 3.7 test 
cases somewhat aligned with their Python 3.8 counterparts.

Nick Coghlan  added the comment:

Mark & Tim: thanks for the discussion and clarifications above, I learned some 
new things myself!

Sanyam: thanks for the patch, and for your patience while we figured out what 
we wanted the new wording to actually say :)

(Technically the backport PRs are still in progress, but I'll track that 
through the GitHub notifications)
