[issue33000] IDLE Doc: Text consumes unlimited RAM, consoles likely not

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Roger, John may have run IDLE rather than IDLEX.  This issue is about 
documenting the fact that tk Texts do not throw away lines, and will accept 
text until there are memory problems.  (Command Prompt, for instance, only 
keeps the last N lines, where N defaults to 300 (not enough to see a test suite 
run) and is max .)

[issue35142] html.entities.html5 should require a trailing semicolon

[Daniel Lovell]

Daniel Lovell  added the comment:

Ah, I stupidly overlooked that as I'm only familiar with this HTML5 
specification: 
https://html.spec.whatwg.org/multipage/syntax.html#character-references

Where it states that characters MUST be terminated with a semicolon. Honestly 
never seen it done otherwise.

[issue35140] encoding problem: gbk

[Windson Yang]

Windson Yang  added the comment:

If I understand your question correctly, you should save the file(the one 
contain Chinese chars) with GBK encoding using your editor. Otherwise, your 
editor would save it using the default encoding which led to python can't 
decode it correctly.

[issue35142] html.entities.html5 should require a trailing semicolon

[Daniel Lovell]

New submission from Daniel Lovell :

html.entities.html5 keys should either require a trailing semicolon. The Python 
docs say:

html.entities.html5
"A dictionary that maps HTML5 named character references [1] to the equivalent 
Unicode character(s), e.g. html5['gt;'] == '>'. Note that the trailing 
semicolon is included in the name (e.g. 'gt;'), however some of the names are 
accepted by the standard even without the semicolon: in this case the name is 
present with and without the ';'. See also html.unescape()."

https://docs.python.org/3/library/html.entities.html?highlight=html

However, it is not clear without looking at the source which keys require the 
semicolon and which do not. Taking a look at the source, the number which 
require a trailing semicolon vastly outnumber the others.

For simplicity and continuity with the w3.org standard HTML5 Character Entity 
Reference Chart - I recommend that the trailing semicolon be required. As they 
are in HTML5: https://dev.w3.org/html5/html-author/charref

My recommendation could then be extrapolated to say we should require the 
ampersand as HTML5 does, but I don't think this revision should be taken this 
far unless others agree.

[issue35136] test_ssl fails in AMD64 FreeBSD CURRENT Shared 3.6 buildbot

[Kubilay Kocak]

Kubilay Kocak  added the comment:

The version in base is:

/usr/bin/openssl version
OpenSSL 1.1.1-freebsd  11 Sep 2018

There is a version from ports also installed at a different prefix, which I 
don't believe Python picks up by default unless Modules/Setup or --with-openssl 
(is this in 3.6?) is used.

I don't believe either, or anything else non-default is used for this buildbot 
environment, either in the worker configuration, or the builder configs 
themselves.

If test_ssl isnt failing on 3.x on this same worker, then presumably there's a 
commit or fix that hasn't been backported.

[issue25416] Add encoding aliases from the (HTML5) Encoding Standard

[Felipe Rodrigues]

Felipe Rodrigues  added the comment:

Ezio, I have issued a simple PR that adds just the two aliases cited in the 
issue's initial message. I would like to implement tests but as I wrote in the 
PR's message, I'm not really sure how to proceed with that. bpo-18624 is really 
related to this issue and in there is a reference to a test_codecs.py file that 
I did not find.

If you could give me a few pointer on how to proceed, I'll be glad to improve 
my PR, add tests and even add all the other aliases that are missing.

[issue35139] Statically linking pyexpat in Modules/Setup fails to compile on macOS

[Maxime Belanger]

New submission from Maxime Belanger :

Uncommenting the following line in `Modules/Setup` leads to a compiler error on 
macOS (tested w/ Xcode 10):

```
./Modules/expat/xmlparse.c:92:3: error: You do not have support for any sources 
of high quality entropy enabled. For end user security, that is probably not 
what you want.
  Your options include: * Linux + glibc >=2.25 (getrandom): HAVE_GETRANDOM, 
* Linux + glibc <2.25 (syscall SYS_getrandom): HAVE_SYSCALL_GETRANDOM, * BSD / 
macOS >=10.7
  (arc4random_buf): HAVE_ARC4RANDOM_BUF, * BSD / macOS <10.7 (arc4random): 
HAVE_ARC4RANDOM, * libbsd (arc4random_buf): HAVE_ARC4RANDOM_BUF + HAVE_LIBBSD, 
* libbsd
  (arc4random): HAVE_ARC4RANDOM + HAVE_LIBBSD, * Linux / BSD / macOS 
(/dev/urandom): XML_DEV_URANDOM * Windows (RtlGenRandom): _WIN32. If insist on 
not using any of
  these, bypass this error by defining XML_POOR_ENTROPY; you have been 
warned. If you have reasons to patch this detection code away or need changes 
to the build system,
  please open a bug. Thank you!
```

I believe this is due to `setup.py` being out of sync with `Modules/Setup`, 
which defines `XML_POOR_ENTROPY`. I'll attach a patch that resolves the issue 
for me.

FYI I tried to be very careful on each change to never modify the *public* C 
API.

But I modified the Py_BUILD_CORE API. This is fine since this API can change 
anytime, and it must not be used outside Python.

[issue35138] timeit documentation should have example with function arguments

[davidak]

New submission from davidak :

It is described here: https://www.pythoncentral.io/time-a-python-function/

I have just tested it. Works as expected.

Best would be if timeit supports this natively.

[issue35137] Exception in isinstance when __class__ property raises

[Anthony Sottile]

New submission from Anthony Sottile :

This may be intentional, but the behaviour changed between python2 and python3. 
 Want to make sure it's intentional as we're working (hacking) around this in 
pytest: https://github.com/pytest-dev/pytest/pull/4284

The actual impact on pytest is the use of `inspect.isclass`

Simplest reproduction:

class C(object):
@property
def __class__(self):
raise AssertionError('fail')

isinstance(C(), type)


In python2.x:

$ python2 t.py
$

In python 3.x:

$ python3.7 t.py
Traceback (most recent call last):
  File "t.py", line 6, in 
isinstance(C(), type)
  File "t.py", line 4, in __class__
raise AssertionError('fail')
AssertionError: fail


In python2.x it appears there's code which intentionally avoids this case:

https://github.com/python/cpython/blob/ca079a3ea30098aff3197c559a0e32d42dda6d84/Objects/abstract.c#L2906-L2909

Mostly want to see if this is intentional or not, it does feel odd that 
`inspect.isclass` raises instead of returning `False` in this case, but it's 
unclear if it's a problem with `isclass` or `isinstance`

[issue20596] Support for alternate wcstok syntax for Windows compilers

[Erik Janssens]

Erik Janssens  added the comment:

I created a github pull request based on the last patch of Jeffrey Armstrong.

Since mingw now also has a wcstok_s function, the discrimination between 
wcstok/wcstok_s is now based on MS_WINDOWS being defined, as was the case in 
Modules/main.c.

Is this correct, or should it be based on the detected compiler ?

Karthikeyan Singaravelan  added the comment:

Thanks for the report. The issue tracker deals with reports for CPython and 
issues related to pip are not maintained here. Please file a doc issue at 
https://github.com/pypa/pip/ . `--download` was deprecated with 
https://github.com/pypa/pip/pull/3085 and PR reports it's for removal with pip 
10. Usage of `pip download` as a toplevel command is encouraged and can be used.

Relevant doc needs to be updated at 
https://github.com/pypa/pip/blob/master/docs/html/user_guide.rst.


Thanks

[issue35135] pip install --download option does not exist

[Pedro]

New submission from Pedro :

https://pip.pypa.io/en/stable/user_guide/#installing-from-local-packages states 
that you can use a --directory option with the install subcommand. This fails 
with pip 18.1 on both Python 2.7 on SLES12 and Python 3.6 on Windows 10:

==

pip install --download my_dir -r reqs.txt

Usage:
  pip install [options]  [package-index-options] ...
  pip install [options] -r  [package-index-options] ...
  pip install [options] [-e]  ...
  pip install [options] [-e]  ...
  pip install [options]  ...

no such option: --download

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

@Tester Thanks for the report. I looked at the crash report and I couldn't see 
CPython crashing with a segfault. I think it's a crash from another application 
which might be running the interpreter and can't handle the error raised by 
CPython for invalid data being decoded. This is something the application which 
crashes has to handle when CPython returns the expected trace back and I don't 
see any fix from CPython's end. Correct me if I am wrong here.

Relevant CPython trace back :

[issue35134] Move Py_LIMITED_API to Include/pycapi/

[STINNER Victor]

New submission from STINNER Victor :

The PEP 384 "Defining a Stable ABI" introduced Py_LIMITED_API define to exclude 
functions from the Python C API. The problem is when a new API is introduced, 
it has to explicitly be excluded using "#ifndef Py_LIMITED_API". If the author 
forgets it, the function is added to be stable API by mistake.

I propose to move the API which should be excluded from the stable ABI to a new 
subdirectory: Include/pycapi/.

To not break the backward compatibility, I propose to automatically include new 
header files from existing header files. For example, 
Include/pycapi/pyapi_objimpl.h would be automatically included by 
Include/pycapi/pycapi_objimpl.h.

New header files would have a "pycapi_" prefix to avoid conflict Include/ 
header files, if Include/pycapi/ directory is in the header search paths.

This change is a follow-up of bpo-35081 which moved Py_BUILD_CORE code to 
Include/internal/.

It is also part of a larger project to cleanup the C API, see:

[issue35133] Bugs in concatenating string literals on different lines

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

The following PR fixes many bugs related to concatenating string literals on 
different lines. There are two kinds of errors:

1. Missed space. The first line is ended with a word, and the second line is 
started with a word. When they are concatenated, there is no space between 
words. This is the same issue as issue35128, but not only in warning messages, 
and not only in Python.

2. Missed comma in a list of string literals. This leads to concatenating the 
last string in the first line and the first list in the second line.

[issue35122] Process not exiting on unhandled exception when using multiprocessing module

[akhi singhania]

akhi singhania  added the comment:

Thank you very much for the reply and the link.  It seems like I escaped that 
bit in the documentation, my apologises.  I can confirm that using 
cancel_join_thread() removes the need for explicitly calling queue.close().

May I please ask for some more clarification if you do not mind.  My 
understanding now is that, there are two scenarios to consider when a process 
using queues tries to exit:

- The default behaviour seems to be that the process must flush the queue 
before it exits.  This is useful as it will ensure that none of the queued data 
is lost which can be very useful in some circumstances.

- The alternate behaviour (which can be enabled by setting 
cancel_join_thread()) is that you don't care about losing the data in the queue 
and just want to exit.  Again this can be useful in some circumstances if you 
don't care if the data is lost and emptying out the queue might potentially 
take a long time.


Does the above sound about right?  Thank you very much for your explanation and 
sorry again for the noise.

[issue35132] python-gdb error: Python Exception Type does not have a target

[Dylan Cali]

New submission from Dylan Cali :

Python version: 3.6.6-debug
System: Kernel: 4.15.0-38-generic x86_64
Distro: Linux Mint 18.2 Sonya
CPU:Quad core Intel Xeon E3-1505M
Memory: 32018.6MB


Expected:

py-list and py-bt to print the current python frame and traceback when 
attaching to a hung python process with gdb, a debug build of python, and 
cpython/Tools/gdb/libpython.py loaded.


Actual:

py-list and py-bt fail with:

Python Exception  Type does not have a target.:
Error occurred in Python command: Type does not have a target.

Invoking 'set python print-stack full' in gdb produces the more useful:

Traceback (most recent call last):
  File "", line 1, in 
  File "~/git/cpython/Tools/gdb/libpython.py", line 916, in filename
  File "~/git/cpython/Tools/gdb/libpython.py", line 1158, in proxyval
RuntimeError: Type does not have a target.

so it is failing at:

fields = gdb.lookup_type('PyUnicodeObject').target().fields()

in libpython.py [1].


Reproduce:

I haven't been able to create a simple standalone program that triggers the 
failure.  I am working on a PR for Keras to try and fix the multiprocessing 
support in some of their utility classes.  Currently the tests are sporadically 
hanging and my intention was to use python's gdb integration to identify 
exactly where and why the hangs are occuring... but I can't get that 
information at the moment because of the error above when invoking py-list and 
py-bt.

So, unfortunately, the shortest path to reproduce is to checkout the PR branch, 
run the offending tests, connect with gdb, and invoke py-list/py-bt:

* install a debug version of 3.6.6 if one isn't already available
* git clone https://github.com/calid/keras.git -b fix-multiprocessing-hang
* cd keras
* pip install -e .[tests]
* pip install tensorflow
* py.test tests/keras/utils/data_utils_test.py
* wait for hang
* gdb -p 
* invoke py-list or py-bt


I am happy to poke around in libpython.py and try to fix/submit a PR myself, 
but I'm not at all familiar with the python internals so I would need some 
guidance.  And obviously let me know if this isn't actually a bug but rather 
environment related/user error.

Thank you!

[issue35131] Cannot access to customized paths within .pth file

[Valentin Zhao]

New submission from Valentin Zhao :

I want to manage all the packages that I installed so every time adding package 
I set "--target" so the package will be downloaded there. Then I wrote the 
directory in a .pth file which is located in "/Python36/Lib/site-packages" so I 
could still get accessed to all the packages even though they are not located 
within "Python36" folder.

However, my current user name of Windows is a Chinese name, which means the 
customized path I mentioned before has Chinese characters within it, thus the 
.pth file will be also encoded with 'gbk'. Every time I would like to import 
these packages will get "UnicodeDecodeError: 'gbk' can't decode byte xxx...".

Fortunately I have found the reason and cracked the problem: python read .pth 
files without setting any encoding. The code is located in 
"Python36/Lib/site.py"

def addpackage(sitedir, name, known_paths):
if known_paths is None:
known_paths = _init_pathinfo()
reset = True
else:
reset = False
fullname = os.path.join(sitedir, name)
try:
# here should set the second param as encoding='utf-8'
f = open(fullname, "r")
except OSError:
return
# other codes

And after I doing this, everything goes well.

[issue35117] set.discard should return True or False based on if element existed.

[tzickel]

tzickel  added the comment:

I would think that the .discard is the equivalent of .pop in dict. (instead of 
wasting time once checking and once removing, also the data in a set is the 
data, there is no value to check). 

Even the standard lib has lots of usage of dict.pop(key, None) to not throw an 
exception. (instead of not using None, and catching exception).

What sets this apart from other mutating APIs is that it does not throw an 
exception.
