[issue43654] IDLE: Applying settings disables tab completion

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Investigation of this issue is complicated by the fact that the editor test 
widgets are wrapped by multicall.MulticallCreator.  It intercepts bind and 
event method calls (other than event_generate) for user pseudoevents.  It keeps 
its own map of pseudoevent names to handler and key sequences instead of 
passing the information on to tk.

The custom entry for "<>" is the same,
 [>, [(0, 0, 
'Tab')]]
both before deactivate_... and after activate_... .

I determined this by adding calls like the following
  print('ei5 ', instance.text.event_info('<>'))
and adding the following to the event_info(virtual) override.
  print('mei', virtual, self.__eventinfo.get(virtual))

I will next look at the custom binding data that should map keys to event 
handlers.

[issue37945] [Windows] test_locale.TestMiscellaneous.test_getsetlocale_issue1813() fails

[David Bolen]

David Bolen  added the comment:

I don't have much of a horse in the race, but since the test has historically 
been skipped on Windows, and the test hasn't and doesn't work on Windows, 
modifications to restore the skip behavior seem reasonable to me.  The trigger 
for this issue was Windows adding support for underscore in locale names (like 
tr_TR) so the test began executing.  But it's not a regression or new issue, 
it's just existing reality becoming exposed.

The user machine and buildbot discrepancy can be attributed to version 
differences, as the buildbot hadn't yet received the same underscore locale 
name support.

I'd be fine with removing the test entirely - always skipping on a failure just 
seems pointless.  Then again, issue1813 created the test for a purpose on other 
systems, though even back then it appears it was complicated.  Leaving the test 
but skipping known failing systems (I guess at least Windows and OpenBSD) might 
be slightly less intrusive of a change, assuming the test is still serving a 
purpose elsewhere.

Separately, there's a lot of useful/interesting detail here which could inform 
any eventual normalization changes on Windows, should the underlying issue be 
deemed worthy of addressing.  But that seems like something that could be a 
distinct operation from clearing up the test issue.

[issue43593] pymalloc is not aware of Memory Tagging Extension (MTE) and crashes

[Neil Schemenauer]

Neil Schemenauer  added the comment:

I've merged PR 14474 so you can just test with an up-to-date "main" branch and 
see if that fixes the problem.  I would expect it should fix the problem since 
with the radix tree arena tracking, no memory unsanitary behaviour remains.

[issue43567] regen.vcxproj cannot regenerate some necessary files

[Jiaxin Peng]

Jiaxin Peng  added the comment:

I did:
- modified Grammar/python.gram
- added new operator to compare_op_bitwise_or_pair
- added corresponding token to Grammer/Tokens
- build.bar --regen
- not having Include/Python-ast.h and Python/Python-ast.c

I agree that a regen.bat that using a system python is better solution. 
regen.vcxproj is confusing.

[issue43567] regen.vcxproj cannot regenerate some necessary files

[Guido van Rossum]

Guido van Rossum  added the comment:

Workaround:

For opcode.py changes, I can probably use the following strategy:

- build.bat
- Add new opcode to opcode.py
- build.bat --regen
- build.bat
- Make changes to compile.c and ceval.c to implement new opcode
- build.bat

For the parser perhaps you can adopt a similar strategy, where you first
add new tokens and get the code generation working?

[issue43567] regen.vcxproj cannot regenerate some necessary files

[Guido van Rossum]

Guido van Rossum  added the comment:

I've found build.bat --regen unreliable myself. I went over it with Steve and 
one issue that came up is that it uses the python.exe that is built to run the 
code generation scripts; OTOH on Linux/Mac these scripts are run using a 
suitable pre-existing Python binary, e.g. a recent enough system Python. 
(However, the frozen files require a binary (_freeze_importlib).

It will take some time to refactor things so that this is more usable.

Perhaps instead of (or in addition to) doing everything via .vcxproj files, we 
could have a simple(r) regen.bat script that runs all the regen scripts (or at 
least the non-freeze ones) using the system Python?

FWIW my own issues weren't with the parser, they were with regenerating 
opcode.h and opcode_targets.h.

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Steve Dower]

Steve Dower  added the comment:

> "__pypackages__" doesn't seem like a drop-in replacement for virtual 
> environments.
Right, it's not. But if enough people adapt their workflows to use 
[something like] it rather than relying on having a local copy of 
python.exe in order to launch, apps that currently assume that their 
subprocesses don't have their own children would be correct again.

If it was a drop-in replacement, we'd have dropped it in already. All 
the drop in replacements come with similar issues, which is why we need 
to change things more broadly in order to handle all the use cases that 
exist.

[Steve Dower]

Steve Dower  added the comment:

I published the Windows OpenSSL builds and retriggered your PR builds, 
Christian.

It looks like we should probably bring up the next release for this, if only 
because that will cause server users to do rebuilds/updates that they may 
otherwise not. I doubt there are many public-facing servers running on Windows 
or macOS (most Windows ones let IIS handle TLS anyway, rather than doing it in 
Python), though Brad may be an exception here ;)

It's a buffer overflow, or at least a crash related to uninitialized bytes. See:

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Eryk Sun]

Eryk Sun  added the comment:

> "C:\Program Files\WindowsApps\venvlauncher.exe"

The above was supposed to be "C:\Program 
Files\WindowsApps\Python...\venvlauncher.exe", where "Python..." is the elided 
name of the package directory.

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Eryk Sun]

Eryk Sun  added the comment:

> the Store package, which can only be *executed* from outside its 
> container (we can't load the DLL directly).

The idea I was pondering was to create "python.exe" in the virtual environment 
as an appexec link to "C:\Program Files\WindowsApps\venvlauncher.exe" and 
reverse engineer whatever is needed to make CreateProcessW() build the required 
access token. For example, if it simply checks for the existence of 
"venvlauncher.exe" in the user's "WindowsApps" directory, then set that as an 
appexec alias as well.

However, it can't work for a simple reason. For an appexec link, 
CreateProcessW() reads and executes the target of the link. The original 
appexec link path is not retained, so there's no way for the "venvlauncher.exe" 
process to know about the virtual environment.

> PEP 582

"__pypackages__" doesn't seem like a drop-in replacement for virtual 
environments. The current directory (in the REPL) and script directory have 
always had precedence over the standard library, except in isolated mode, so 
"__pypackages__" seems more about providing a directory for Python packages 
that's neatly separated from the script directory. I presume also that 
"__pypackages__" would be added to sys.path even in isolated mode, though the 
PEP makes no mention of it.

[issue43662] test_tools: test_reindent_file_with_bad_encoding() fails on s390x RHEL7 LTO + PGO 3.x

[STINNER Victor]

STINNER Victor  added the comment:

Oh. The failure is random:

* 934 green
* 933 red: test_reindent_file_with_bad_encoding failed
* 932 green
* 931 red: test_reindent_file_with_bad_encoding failed

* (... older builds are all green ...)
* 775 orange

* (... more green builds ...)

This buildbot uses PGO+LTO optimization on RHEL7 with "gcc (GCC) 4.8.5 20150623 
(Red Hat 4.8.5-44)". Can it be a compiler issue? Are other buildbots affected?

[issue43662] test_tools: test_reindent_file_with_bad_encoding() fails on s390x RHEL7 LTO + PGO 3.x

[STINNER Victor]

STINNER Victor  added the comment:

test_tools.test_reindent_file_with_bad_encoding() runs 
Tools/scripts/reindent.py.

The check() function of this script calls:

with open(file, 'rb') as f:
try:
encoding, _ = tokenize.detect_encoding(f.readline)
except SyntaxError as se:
errprint("%s: SyntaxError: %s" % (file, str(se)))

But I don't think that the buildbot reached this line since the stderr message 
doesn't start with the input filename. For example, locally, I get the expected 
error:

$ ./python Tools/scripts/reindent.py -r Lib/test/bad_coding.py; echo $?
Lib/test/bad_coding.py: SyntaxError: unknown encoding for 
'Lib/test/bad_coding.py': uft-8

[STINNER Victor]

STINNER Victor  added the comment:

> SyntaxError: encoding problem: encoding

This "encoding problem: %s" error message comes from check_coding_spec() of 
Parser/tokenizer.c. The "%s" argument is the cs variable which is initialized 
by get_coding_spec().

test_tools.test_reindent_file_with_bad_encoding() uses Lib/test/bad_coding.py 
which contains a single line:

# -*- coding: uft-8 -*-

The expected encoding name is "uft-8", not "encoding".

Assume it'll be the next scheduled release (though I haven't looked at the

I'm starting the Windows build process now, but that only gets us far enough to

[issue37745] 3.8b3 - windows install gui/ inconsistent options

[Steve Dower]

Steve Dower  added the comment:

The main problem with adding Python to PATH is interfering with other 
application's DLL and executable resolution order, as well as the inevitable 
confusion when multiple PATH updates do not play well together (which they 
don't).

The best thing you can do with your students (those on Windows 10, at least) is 
get Python from the Microsoft Store, which is able to do the PATH updates 
property (and you can modify them through the built-in "Manage App Execution 
Aliases" control panel if you have multiple).

Any other solution that is reliable, maintainable (for users) and usable is 
going to require significantly more development (and will break many existing 
users' workflows, but hopefully not too badly) than just flipping the checkbox. 
But some of us are thinking about it (me in particular, since I'm sick to death 
of being abused over this issue but would rather find a good way to fix it than 
just quit).

[issue43312] Interface to select preferred "user" or "home" sysconfig scheme for an environment

[Tzu-ping Chung]

Tzu-ping Chung  added the comment:

Gentle ping again :) I’ve also created a PR for this.

> The Debian/Ubuntu packages have a local patch for distutils/setuptools 
> introducing an --install-layout option.  Maybe have the same for pip?

Pip already has a similar mechanism. The default layout is `prefix` and you can 
change the installation prefix with `--prefix`; `home` and `user` layouts can 
be specified with `--home={base}` and `--user`.

> So the problem to solve is
>
>  - let a "sudo pip install" fail by default on the real system
>  - let the same install succeed in a docker environment, or any other "image".

These need to be done in pip, so we’ll have a separate discussion on them 
elsewhere.

>  - behave transparently on venv and virtualenv installations.

This is what this issue tries to address. A distribution can overwrite 
`sysconfig.get_default_scheme()` and `sysconfig.get_preferred_scheme(variant)` 
to return the correct scheme based on whether the current Python is in a 
virtual environment (by detecting `sys.prefix` and `sys.base_prefix`, I think).

When in a virtual environment, it can return the same scheme as the upstream. 
Outside of a virtual environment, it can do whatever the platform sees fit, and 
pip (or whatever calls sysconfig) will install things into wherever it’s told 
to by the two functions.

[issue43624] Add underscore as a decimal separator for string formatting

[Terry Davis]

Terry Davis  added the comment:

Victor,
> '_.f' would be the same as '_f'?
No, the example in my original post is wrong, '_.f' isn't allowed now.
The proposal should use '_f' to describe the current behavior.

> Should "._f" be allowed to only add underscores in the fractional part? (for 
> consistency?)

Yes, but not for consistency with the above usage, instead it's so both 
fractional and integral underscores can be specified on their own.

Here is my attempt at updating the format spec. The only problem I have with it 
is that it allows a naked '.'; I don't know how to specify "dot must be 
followed by one or both of 'float_grouping' and 'precision'".

Current:
format_spec ::=  
[[fill]align][sign][#][0][width][grouping_option][.precision][type]

Proposed:
format_spec ::=  
[[fill]align][sign][#][0][width][grouping_option][.[float_grouping][precision]][type]
fill::=  
align   ::=  "<" | ">" | "=" | "^"
sign::=  "+" | "-" | " "
width   ::=  digit+
grouping_option ::=  "_" | ","
float_grouping  ::=  "_"
precision   ::=  digit+
type::=  "b" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" | "n" 
| "o" | "s" | "x" | "X" | "%"

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Steve Dower]

Steve Dower  added the comment:

The main motivator for the redirector was to support the Store package, which 
can only be *executed* from outside its container (we can't load the DLL 
directly). Given we want the two distributions to be interchangeable from a 
code POV, it made the most sense to switch both over. That said, there were 
other issues with the previous system that were worth fixing, it just happens 
that a new one was introduced (though it definitely already existed for some 
users - IPC is a complex pattern to get right even when you fully control the 
processes).

I still haven't been able to come up with a viable workaround that doesn't 
break more cases than it helps. Passing the internal environment variable 
around might help, but I don't want to fully support it because then that would 
prevent us fixing this properly!

PEP 582 (or otherwise getting away from virtual environments in favour of some 
other way of having project-specific package installation) may be our best hope.

I like the idea, but we shouldn't invert the dependencies like that. nt/os is a 
lower-level library, and should provide its own implementation (that perhaps 
subprocess could then use).

Minor correction. update_lines_cols() is not provided by the underlying curses 
library, it is a helper defined in Python wrapper. But it is optional, snd 
skipping test is the correct solution. Thank you.

As for the core dump, could you please run the test in verbose mode with 
redirected stdout and stderr and show the result?

./python -m test -vuall test_curses 2>test.err >test.out

What is the default value of TERM? Does the result differ if set TERM=xterm?

[issue43661] api-ms-win-core-path-l1-1.0.dll, redux of 40740 (which has since been closed)

[Tom Kacvinsky]

New submission from Tom Kacvinsky :

Even though bpo#40740 has been closed, I wanted to re-raise the issue as this 
affects me.  There are only two functions that come from this missing DLL:

PathCchCombineEx
PathCchCanonicalizeEx

Would there be a way of rewriting join/canonicalize in getpathp.c (each of 
which uses one of the above functions) to _not_ rely on functions from a 
missing DLL on Windows 7 SP1?  Or has the ship truly sailed on this matter?

@vstinner - The fix doesn't change the behavior of _PyType_Lookup and instead 
just fixes a previous unrelated bug.  The condition will typically ever be hit 
once (at startup) as it's very unlikely that versions will wrap, so there 
should be no performance difference after the fix.

[issue43657] shutil.rmtree fails on readonly files in Windows, onerror not called

[Eryk Sun]

Eryk Sun  added the comment:

> The doc on rmtree states 
> Exceptions raised by onerror will not be caught.
> Does this mean I can't use try/exept inside of onerro

rmtree() does not call onerror() in a try/except statement. An exception raised 
in onerror() will propagate to the scope that called rmtree().

The documentation has an example onerror() handler for Windows readonly files:

import os, stat
import shutil

def remove_readonly(func, path, _):
"Clear the readonly bit and reattempt the removal"
os.chmod(path, stat.S_IWRITE)
func(path)

shutil.rmtree(directory, onerror=remove_readonly)

I'd check whether the exception and function are expected values. For example:

import os, stat
import shutil

def remove_readonly(func, path, exc_info):
"Clear the readonly bit and reattempt the removal"
# ERROR_ACCESS_DENIED = 5
if func not in (os.unlink, os.rmdir) or exc_info[1].winerror != 5:
raise exc_info[1]
os.chmod(path, stat.S_IWRITE)
func(path)

shutil.rmtree(directory, onerror=remove_readonly)

The problem is that

[issue38794] Setup: support linking openssl statically

[Christian Heimes]

Christian Heimes  added the comment:

I introduced several build improvements for better support of custom OpenSSL 
builds in bpo-43466. The issue mentions a new, undocumented, and unsupported 
hack to create a shared extension modules with statically linked OpenSSL. The 
Modules/Setup.local trick works with current Python versions, too. Both the 
hack and the trick hide symbols, too.

I vetoed against official support for static linking because I simply don't 
have capacity to test and support another build flavor.

William, I recommend that you do NOT read commit 
bacefbf41461ab703b8d561f0e3d766427eab367 and do NOT use the undocumented hack. 
Have fun! :)

[issue43659] AIX: test_curses crashes buildbot

[Michael Felt]

New submission from Michael Felt :

Since issue42789 the AIX bot's have crashed - to the extent that the bot's did 
not even return results.

Part of this has been resolved, for now, by using:

$ export TERM=unknown
$ buildbot start buildarea

However, the test still crash because AIX default libcurses.a does not include 
support for update_lines_cols().

This patch should allow test_curses.py to pass in the buildbot.

When run from command-line as:

$ TERM=unknown ./python Lib/test/test_curses.py
.ss..ss
--
Ran 71 tests in 0.121s

OK (skipped=64)
aixtools@cpython2:[/home/aixtools/py3a-10.0]

(When TERM is defined - a core dump still occurs - that will be a new issue and 
a new PR).
