[issue37391] MacOS Touchpad scrolling crashes IDLE

[Terry J. Reedy]

Terry J. Reedy  added the comment:

For future reference: an exception is not a crash.  A crash is a core dump or 
the Mac equivalent.

Anyway, I also cannot reproduce with Python.org python on my Macbook.
  python 3.7.3(v3.7.3:ef4e...) Mar 25, 2019 16:52:21
  Clang 6.0 (...) on Darwin
Where did you get your Python installer?  Did it include tck/tk?  If not, 
perhaps python3.exe and the tcl/tk being used do not match.

Does IDLE work at all?  Can you click Help and About IDLE?  If so, what is the 
tk version? 

I used the pad to move the cursor over the scrollbar slider, held my left 
finger down on the left side of the pad, and moved the slider and file display 
with my right finger.  Is this what you did?

>From the traceback it appears that the exception occurred in the C code of  
>_tkinter or more likely, the C code of tcl/tk, before any of IDLE's 
>python-coded event handlers are called.  Hence, Ned's comment.

[issue37397] Trap in Python 3.5 under Apache 2.2 when Django database returns 'None'.

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

This tracker deals with CPython development and this doesn't seem like am issue 
in CPython but rather an error in your program. I assume you might be passing 
None somewhere in the django ORM query that is expecting a number. Also please 
don't post open web server endpoints with debug mode on. The debug server is 
not meant to be exposed to the internet. This question could find better answer 
from stackoverflow.

[issue37396] [2.7] PCbuild/pythoncore.vcxproj kills the wrong program

[Zachary Ware]

Zachary Ware  added the comment:

How can you tell that $(PyDebugExt) is not set?  Note that the "Killing any 
running python.exe instances..." line is hard-coded, it does not currently 
include $(PyDebugExt) (though it probably should).  Adding that to the message 
would be a good first step; backporting GH-9901 to 2.7 would probably also be 
good even though it was solving a different issue.

[issue37397] Trap in Python 3.5 under Apache 2.2 when Django database returns 'None'.

[JOMO WILLACY]

New submission from JOMO WILLACY :

I am using Python 3.5 with Django and the Python web server and Apache 2.2 web 
server.
I am querying the database for a "drug_name" and an "insurer" - # and minimum 
"price".

Here is what works and what does not work

Valid Drug Name   Valid Insurer WorksPython web Server  Apache

Epipen   2   YesYes   Yes

Lisenopril   2   YesYes   Yes

Naftin   7   YesYes   Yes



Invalid Drug NameInsurer  Works Python Server   Apache

LicenoprilYesYes  Yes

Licenopril 2 Yes  No


In the last case up above it traps and the server logs at 
/var/www/logs/error.log say "Unhandled Exception".

This is where it traps ans what it says :

 Cannot convert str to float  :  'None'

File 
"/usr/local/lib64/python3.5/site-packages/django/db/models/fields/__init__.py"  
line 1747, in get_prep_value

   return float( output_value )


I then went into the file where the trap occurred and I added a try catch like 
the function after line 1747 and the problem went away.

The trap only happens under Apache.

If you wish to reproduce this problem then go to these links and try the input 
listed above :

Python Web Server :

   http://34.200.216.166:8000/health_insurer2/minimum_price_for_drug/


Apache Web Server :

   http://34.200.216.166/health_insurer2/minimum_price_for_drug/


As an aid I have left debug=on in django so you will be able to trace the trap 
in the browser

The file that I am running is views.py
I am running Amazon AMI Linux in the cloud.


Sincerely Yours,


Jomo Willacy

[issue37396] [2.7] PCbuild/pythoncore.vcxproj kills the wrong program

[STINNER Victor]

New submission from STINNER Victor :

x86 Windows XP 2.7:
https://buildbot.python.org/all/#/builders/45/builds/429

Killing any running python.exe instances...
...
C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppClean.targets(74,5): 
warning : Access to the path 
'd:\cygwin\home\db3l\buildarea\2.7.bolen-windows\build\PCBuild\python_d.exe' is 
denied. 
[d:\cygwin\home\db3l\buildarea\2.7.bolen-windows\build\PCbuild\python.vcxproj]

It's a debug build: it should kill python_d.exe, not python.exe.

--

PCbuild/pythoncore.vcxproj uses:

  
ClCompile
true
  

which comes from PCbuild/pyproject.vcxproj:

  


  

Problem: it seems like $(PyDebugExt) is not set to "_d" in 
PCbuild/pyproject.vcxproj.

Should PCbuild/pyproject.vcxproj explicitly import python.props which defines 
it?

[issue37395] Core interpreter should be linked with libgcc_s.so on Linux

[Zack Weinberg]

New submission from Zack Weinberg :

There are several existing issues (e.g. #18748 and #35866) where at least part 
of the problem is that GNU libc tried to dlopen() `libgcc_s.so` at a moment 
when that's not safe, e.g. during thread or process shutdown.  This converts a 
recoverable error into a deadlock or crash.

This is arguably a bug in glibc, but Python can easily work around it by 
linking the core interpreter (the `python` executable and/or `libpython.so`) 
with libgcc_s at build time (`-lgcc_s`) on Linux.  It will then be loaded 
already if and when it's needed, and glibc won't try to load it on demand.

In order for this to be 100% reliable, it needs to be at least theoretically 
possible for code within the interpreter to call a function defined in 
libgcc_s.so. `_Unwind_Backtrace` is probably the most practical option.  (See 
https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/baselib--unwind-backtrace.html
 .)

[issue37386] [EASY] test_io: test_large_file_ops() failed on AMD64 Windows7 SP1 3.x with: [Errno 28] No space left on device

[STINNER Victor]

STINNER Victor  added the comment:

> To check - do we definitely want to just skip the test if the below OSError 
> is thrown?

Note: I don't propose to ignore any OSError, only if exc.errno == errno.ENOSPC.

> Could we attempt to clean wherever the test is writing to before the test is 
> run/figure out what is using all the space?

Maybe some tests can be enhanced, but that's not directly related to this issue.

In general, Python tests don't leak any resource: memory, files, etc. If there 
is a leak, it must be fixed.

The test creates a file which can take up to 2 GiB on the disk. It's a big 
file. I don't think that other tests leak such huge file.

[issue37394] Fix pure Python implementation of queue

[Pablo Galindo Salgado]

New submission from Pablo Galindo Salgado :

The test for the queue module are not testing correctly both the C and the 
Python implementation of the queue. A consequence is that some errors are being 
overseed (like the fact that an AttributeError is used instead of an 
ImportError to catch when importing _queue fails).

[issue37335] Add 646 ASCII alias to locale coercion tests.

[STINNER Victor]

STINNER Victor  added the comment:

test_c_locale_coerce should use "codecs.lookup(encoding).name" to get the 
normalized name of an encoding, rather than fragile:

data = data.replace(b"ANSI_X3.4-1968", b"ascii")
data = data.replace(b"US-ASCII", b"ascii")

the proposed pattern is even more dangerous:

 data = data.replace(b"646", b"ascii")

I'm not sure where encodings should be normalized. Maybe around 
_check_child_encoding_details().

For the PR, please write it for the master branch.

[issue37391] MacOS Touchpad scrolling crashes IDLE

[Ned Deily]

Ned Deily  added the comment:

FWIW, I can't reproduce the failure using either Python 3.7.3 from either the 
python.org binary installer or a current MacPorts 3.7.3.  But that's not 
surprising as the issue is most likely in Tk rather than IDLE or Python itself. 
 Can you supply the output from the following commands in a terminal session, 
assuming python3 is the same interpreter used to run IDLE?

python3 -m test.pythoninfo
otool -L $(python3 -c 'import _tkinter;print(_tkinter.__file__)')

[issue37380] subprocess.Popen._cleanup() "The handle is invalid" error when some old process is gone

[STINNER Victor]

STINNER Victor  added the comment:

> 2) ignore EBADF(OSError: [WinError 6] The handle is invalid) in terminate() 
> and probably some other methods

That sounds like a bad idea. We should avoid using a handle if it can become 
invalid out of our control. A handle might be recycled, no?

[issue37140] ctypes change made clang fail to build

We probably need a second parg->obj to keep self alive for as long as 
copied_self. Or pack it into a tuple.

Having a repro test for this would be ideal, especially if we can make it 
happen (even crash) on all platforms. The double-free issue would seem to be 
real, and I don't want it to crash on Windows either.

[issue37390] Generate table of audit events for docs

[Steve Dower]

Steve Dower  added the comment:

I took your code and made some improvements:

https://github.com/python/cpython/compare/master...zooba:bpo37390

In particular, I added the backlinks from the table (but unfortunately they all 
go to the line of text we generate for the ..audit-event directive, and not the 
top of the section :( ) and debugged some of the weirdness of generating tables 
in docutils.

Feel free to pull my changes and take back over if there's more you want to do!

> The issue strikes back:

Not good. This build was run after I deployed the new buildbot configuraiton, 
with the new "cleantest" step, but it has no "cleantest" step. Maybe this job 
was scheduled before the new configuration was deployed?

I rebuilt this build to see if it gets "cleantest" step:
https://buildbot.python.org/all/#/builders/103/builds/2701

Note: I'm not surprised that the issue strikes back. It happens all the time 
with buildbots...

[issue37390] Generate table of audit events for docs

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I think my approach suffers from the drawback where duplicate items cannot be 
separated correctly as you have mentioned. Example as below where 
socket.connect and socket.connect_ex emit same event and I am not able to 
retrieve the function at which the audit event block is present thus generating 
the same entry twice in the table. Maybe I need to store some more metadata.

1153:.. method:: socket.connect(address)
1165:   .. audit-event:: socket.connect "self address"
1174:.. method:: socket.connect_ex(address)
1183:   .. audit-event:: socket.connect "self address"

> * include links back to the section where they came from

Sphinx doesn't seem to support hyperlinking to line numbers. One approach would 
be to just link to the functions that emit the events that could solve the 
above problem too.

I did this as a PoC and kind of stuck with moving the file to a separate to a 
different table of content. I also seemed to have hit a sphinx bug that I 
couldn't get out of and my skills are limited too in Sphinx. I will give it 
another try over this week to see if I can come up with something mergeable :)

[issue37390] Generate table of audit events for docs

[Steve Dower]

Steve Dower  added the comment:

Awesome! I was just making a start on this too, and it looks like we were doing 
nearly identical work. Happy to let you keep going on it!

Some things that I thought would be worth doing:
* combine equivalent events (warn if names match but arguments are different)
* include links back to the section where they came from
* include a "CPython implementation detail" message, and maybe mention that the 
table is generated from the docs

I think for the formatting, we'll have to rearrange how the *args* variable is 
created initially (so that we store the original names, not the `` marked ones) 
and then use nodes.literal() when adding them later. But this is pushing the 
boundaries of my Sphinx/docutils skills as well :)

StreamReader and StreamWriter and to have appropriate signatures for the 
methods. I will try to raise a PR this week. I also realize there are no 
docstrings for the new functions like connect, connect_read_pipe, 
connect_write_pipe etc. Is it worthy enough of adding them too in the PR?

[issue37384] Compiling Python 3.7.3 from source and getting all sorts of errors on Debian?

[Eryk]

Eryk  added the comment:

yeah i managed to fix the uuid already and used:
./configure --enable-optimizations
followed by
make -j 4
and then using
sudo make altinstall

but the issue comes up during the make -j 4 process, strange thing is before 
using thee 'uuid' fix i mentioned and found on here I didn't have the curses 
issue and now I do, how could I fix this so it compiles without errors? Thanks 
a lot for replying guys :)

[issue37347] Reference-counting problem in sqlite

[Benjamin Peterson]

Benjamin Peterson  added the comment:

The _sqlite3 module clearly is not free of bugs in this area. Binding the 
Python function to the exact lifetime of the sqlite function seems less likely 
to be buggy than replicating sqlite's function reference management 
independently. sqlite3_create_function_v2 was added in 2010; I think we can 
depend on it. Also, won't the callback pretty much be Py_DECREF(something)?

[issue37390] Generate table of audit events for docs

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I just tried an initial attempt at this and a screenshot as attached. I 
followed the approach similar to the one at 
https://www.sphinx-doc.org/en/master/development/tutorials/todo.html to gather 
all todos. The approach was to append all the audit event directives to a list 
as they are collected. I then created an AuditEventListDirective for post 
processing once rst files were read and created an empty page with only the 
audit-event-list-table directive. I rendered the audit items in the list into a 
table and then replaced the audit-event-list-table directive in the page with 
the table content. Unfortunately, I couldn't proceed further due to some odd 
sphinx error during builds on moving this to a new index and limited sphinx 
skills. 

+1 to the idea. It would be helpful to have all the audit events under one page 
for reference.

[issue37250] C files generated by Cython set tp_print to 0: PyTypeObject.tp_print removed

[Stefan Behnel]

Stefan Behnel  added the comment:

Thank you, Petr, for bringing this discussion back on a solid basis, actually 
twice already.

And sorry for causing this problem in the first place. The "tp_print = 0" was 
necessary to fix misbehaviour in Py2, and we should have restricted it to Py2 
back then (that line has been there since late 2013).

I think keeping some kind of a "tp_print" named field in PyTypeObject for now 
is the best we can do. I like Jeroen's PR (thanks for taking care of so many 
things at a time, Jeroen!), and I think we should just go with it.

I'm happy to release a new point release for Cython, as soon as it's clear what 
CPython will do, and how Cython can detect the change to adapt to it.

[issue37384] Compiling Python 3.7.3 from source and getting all sorts of errors on Debian?

[Ned Deily]

Ned Deily  added the comment:

The uuid issue is described in Issue32627 and there is a PR fix for it awaiting 
review (PR 11751).  As Christian notes, the curses issues seems to be related 
to some configure option.  If you haven't already, suggest you start with the 
simplest configure options, so something like:

./configure && make -j2

or 

./configure --prefix=/path/to/installed/location && make -j2 && make install

and, once that is working, then try adding other options.  Please feel free to 
reopen this issue if you find a failing issue and please include all relevant 
details, in particular the exact configure command used and platform details.

[issue37363] Additional PEP578 hooks

[Steve Dower]

Steve Dower  added the comment:

FWIW, I tried looking into how we can prevent or detect monkeypatching of 
"sys.audit", and the answer seems to be that we need to define a custom type 
for the sys module and for sys.__dict__.

I'm not prepared to do that yet, and IMHO there are enough way to detect 
someone patching it to nothing (all your logs disappear) or patching it more 
cleverly (someone ran some pretty complex code to redefine it) and events from 
native code can't be suppressed either, so I think it's fine. 

But I won't refuse a contribution if someone thinks this is a critical scenario 
(though I will push hard to make sure the implementation is solid, as I think 
this is pretty hard to get right).

[issue37378] FatalError: initfsencoding python couldn't find codec Module not found: Encodings

[Steve Dower]

Steve Dower  added the comment:

> Also, just one question: how could python -m pip work but not pip? What are 
> the differences in them?

To answer this, "pip" on its own is essentially like writing the full path to a 
specific python.exe and passing "-m pip". If that Python install has been 
removed or (more likely in this case) is broken, then you'll get the error 
you're seeing.

Fixing your PATH as suggested should do it.

"""
msg346410 - (view)  Author: Daniel W Forsyth (d...@dataforge.on.ca) 
Date: 2019-06-24 14:53

After putting a basic ThreadingUDPServer under load (500 messages per/second)  
I noticed that after a night it was consuming a lot of RAM given it does 
nothing with the data.

On inception, I noticed the _thread count inside the server was growing forever
