[issue25198] Idle: improve idle.html help viewer.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The files uploaded 2015-09-24 and 27 were merged later the same day.  The merge 
in between on 2015-09-25 was shorter and not uploaded separately.  I opened 
#33396 as an index issue for the other items and any new ones.  I open #33397 
for font sizing and changed the title of PR6665.

[issue33397] IDLE help viewer: let users control font size

[Terry J. Reedy]

New submission from Terry J. Reedy :

Dependency of #33396. 

1. Base the initial font sizes on the on the configured editor font size.  Note 
that editor font size defaults to 10 while the current base size is 12.  I did 
not find any explicit discussion of this in the original issue, #16893, or the 
first followup, #25198.  Perhaps Mark Roseman just liked the result, or perhaps 
it made the relative sizing easier.

2. Change font size with Control-Mousewheel.  Manually tested code for doing 
this on Windows, Linux, and MacOS is in turtledemo.__main__.  The three systems 
are wildly different.  What we do here should allow easily doing same for other 
text windows.

Matthias Bussonnier  added the comment:

In the docs it is marked as "going to be removed in 3.7", and emitting 
PendingDeprecationWarning. I supposed it should either be updated to change to 
3.8 and switch PendingDeprecationWarning to DeprecationWarning, or be actually 
removed.

[issue33396] IDLE: Improve and document help doc viewer

[Terry J. Reedy]

New submission from Terry J. Reedy :

The IDLE help doc viewer displays help.html in a tk Text subclass. This index 
issue follows #25198, which fixed three immediate issues, and left the 
following for later.  When tackled, the items below should be separate issues 
and PRs listed as dependencies.  

1. msg251181 Base font size on user config and control-mousewheel.
2. "   " Make within-document html links in work in the viewer.
3. "   " Make Find (^F) work within the viewer.
4. msg251571 Navigate with keys as in editor.
5. msg251556 Open TOC with Key (Esc?, F1?); enhance navigation.

New items:

6. Add Help Doc Viewer doc to Help section.
   I prefer not adding a menu and see an entry as an alternative.

7. 1, 3, and 4 should try to avoid duplicating editor code.  Perhaps we should 
enhance the plain text viewer and use it as a superclass for both base editor 
and html viewer.

[issue33395] TypeError: unhashable type: 'instancemethod'

[Siming Yuan]

Siming Yuan  added the comment:

having a tough time trying to reproduce this issue in pure python.

any clue as to how to create a __repr__ that's unhashable?

class UnhashableRepr(dict):
__repr__ = _testcapi.instancemethod(dict.__repr__)

doesn't work because that turns into a  which becomes hashable.

i'd love to provide a patch, seems trivial to fix, but wouldn't want to do so 
without some tests.

[issue33380] Update module attribute on namedtuple methods for introspection.

[Raymond Hettinger]

Raymond Hettinger  added the comment:

ISTM collections is the correct module reference because that is where the code 
is actually defined.  A debugging tool should look there instead of in the 
calling code.  This is the way other tools work in Python as well:

>>> from collections.abc import Set
>>> class S(Set):
def __init__(self): pass
def __iter__(self): yield 0
def __len__(self): return 0
def __contains__(self, key): return False

>>> S.__or__.__module__
'collections.abc'

>>> from dataclasses import make_dataclass
>>> P = make_dataclass('P', ['x', 'y'])
>>> P.__repr__.__module__
'dataclasses'

Likewise, the various tools that use closures used to report the module where 
the closure was defined rather than the module of the caller's code (see 
functools.cmp_to_key or functools.lru_cache).  I say "used to" because the pure 
Python code is now supplanted by C equivalents where the __module__ attribute__ 
is appropriately set to None:

# Running from PyPy
 from functools import cmp_to_key
 c = cmp_to_key(lambda x, y: 0)
 c.__init__.__module__
'_functools'

The Data Model section of the Language Reference defines __module__ as follows, 
"__module__: The name of the module the function was defined in, or None if 
unavailable."  In the prior version of namedtuple(), the function was defined 
in a virtual module (an execed string).  Now, that the methods are defined in a 
real module, the __module__ attribute should name that real module.

[issue33234] Improve list() pre-sizing for inputs with known lengths

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

@serhiy.storchaka @rhettinger @vstinner Should we better make the 
pre-allocation if the length of the iterable is known (so we call 
PyObject_Length and not PyObject_LengthHint)? This will keep the logic simpler 
(so not shrinking if PyObject_LengthHint gives more than the real length) and 
it will not be as expensive as calling PyObject_LengthHint.

[issue21822] KeyboardInterrupt during Thread.join hangs that Thread

[Antoine Pitrou]

Antoine Pitrou  added the comment:

> I'm guessing this is because of the perceived performance impact?

The problem is polling is pretty detrimental to power saving on modern CPUs.  
There might also be a performance impact that makes things worse :-)

More generally, we really would like locks to be interruptible under Windows, 
as it would be useful in many more situations than joining threads. 
Unfortunately, as you have discovered we have several lock implementations for 
Windows right now.  The SRWLock one is probably difficult to make 
interruptible, but it's never enabled by default.  The Semaphore one looks 
legacy, so could perhaps be removed.  Remains the condition variable-based 
implementation.

I'm guessing this is because of the perceived performance impact?  (That's the 
main thought I have against polling in this case.)  Or is it something else?

I can certainly look at tweaking the 3 mutex implementations I mentioned 
previously, but I do expect that will be a bit more code; I at least wanted to 
put the "simpler" idea out there.  Fully knowing that "simpler" isn't 
necessarily better.

[issue21822] KeyboardInterrupt during Thread.join hangs that Thread

[Paul Goins]

Paul Goins  added the comment:

Focusing on the Windows case specifically...  One way to possibly make this 
work (although perhaps not as clean as may be desired) would be to add polling 
logic into the thread_nt.h version of PyThread_acquire_lock_timed.

That would have the benefit of avoiding the complexity of the various "non 
recursive mutex" implementations (i.e. semaphores vs "emulated" condition 
variables vs native condition variables) and may be less code than setting up 
"alertable" WaitForObjectSignleObjectEx calls (plus whatever else needs to be 
done for the SRW-lock-based code path).

Thoughts or feedback?  (I've not done any mainline Python commits yet so I'm 
totally ready to be completely wrong or misguided here.)

[issue32797] Tracebacks from Cython modules no longer work

Paul Moore  added the comment:

It's silly to think that the loader can *ever* say that there's "certainly" no
source, so debating whether None means that is silly. The only thing None could
*possibly* mean is that the loader can't give you the source. No more, no less.

The key difference is that Python source only needs Python to compile it. We
have Python source on sys.path and Python automatically compiles it to bytecode
as needed. You can't put Cython source on sys.path and have the Python
interpreter compile it for you. Basically, sys.path is for code that the Python
interpreter can (compile and) run, and it's at least arguable that non-Python
source doesn't belong on there.

I'm not trying to *make* that argument, though. All *I* am trying to say is
that it's not exactly surprising if stdlib code doesn't expect to find
non-Python source on sys.path.

... that hasn't worked since Python 3.3, but no-one has noticed or complained
until now.

But the standard library has no need to ever find source for extension modules
(unless I'm unaware of some detail of the Cython/IPython specific situation).
So there's no need for the stdlib to be involved - Cython could define a
protocol for finding source code independently, and IPython (and anything else
that wants to display the source of a Cython extension) could use it.

Point taken.

Note that I haven't said it shouldn't be fixed, merely that I'm not as
convinced, having read this discussion, that having linecache do a path search
if the loader returns None is *necessarily* the best solution here. I do still
feel that if we don't make that change, then the linecache docs should be
clarified, but I wouldn't say the linecache docs on the whole module_globals
argument are very clear in the first place - I certainly wouldn't know how to
use that argument based on the current docs.

I'm going to leave the call on whether your proposed change to linecache is OK
to someone who understands (or has the time to review and confirm) the impact
on the 4 places in the stdlib where it's called with a module_global parameter
- asyncio.base_tasks, bdb (twice) and pdb. What I will say is that the code in
the PR looks fine to me as an implementation of the proposed change.

I'm strongly against introducing any extra complexity into the loader
get_source function signature. I think it's fine as it is, and trying to add
nuances to the meaning behind None will only make life harder for people
implementing loaders.

Ideally, of course, there would be a CythonExtensionLoader that handled this in
get_source. But it's hard to see how such a thing would work as "Cython
extensions" don't look any different from extensions built with C, or Rust, or
anything else.

By "older Pythons" I meant 3.3+. ExtensionFileLoader was introduced in 3.3, so
presumably this issue exists in all versions of Python from 3.3 onwards. I
don't consider 2.7 relevant here, as the import machinery was completely
different then.

Of course, it's up to Cython 

[issue33395] TypeError: unhashable type: 'instancemethod'

[Siming Yuan]

New submission from Siming Yuan :

in Python 3.5 it the pprint.PrettyPrinter mechanism got an overhaul, relying on 
PrettyPrinter._dispatch dict-lookup based on obj.__repr__ type.

This breaks any Cythonized 3rd party libraries that used to be pretty-printable 
in Python3.4.

type(object).__repr__


since instancemethod_hash function has been commented out:
https://github.com/python/cpython/blob/c30098c8c6014f3340a369a31df9c74bdbacc269/Objects/classobject.c#L569


oddly the behavior is different between Linux and Mac.

The same object in Linux returns cyfunction, and is hashable,
where as under the same CPython version in Mac, it returns instancemethod, 
rendering it unhashable.
(based on Cython 0.27.3)

note that this isn't exactly something related directly to the implementation 
of Cython.

the old logic in Python <3.4 pprint was not pretty (pun not intended), but 
relied solely on type checking,
where as the new implementation depends on hashing, which introduces this bug.

I'm not sure that Python 3.6. In case of doubt, I prefer to skip it.

The bug has been fixed in Python 3.7 and master. Thanks Andrés Delfino for your

[issue32797] Tracebacks from Cython modules no longer work

[Jeroen Demeyer]

Jeroen Demeyer  added the comment:

> provide source.

I don't think it is silly: if "None" means that the loader cannot provide the 
source, then it makes sense to continue looking for the source. If "None" means 
that there is certainly no source, then it does not make sense to continue 
looking.

> On the other hand, what is Cython source code even doing on sys.path?

It's specifically installed for tracebacks (and other debugging). In a way, 
it's no different from installing both .py and .pyc files. Nobody questions 
that, even though the .pyc files are sufficient.

> I sort of understand the benefit, but it does seem to be a practice peculiar

Sure, it's particular but it's a real existing scenario.

> and I'm not sure the standard library should deal with it.

Depends what you mean with "deal with it". Basically, all that I'm asking for 
is at least one officially supported way to enable finding sources for 
extension modules. There are many possible ways to fix this, that's why I made 
this post to python-ideas.

> I'm struggling to see how a Python programmer would benefit from access to 
> the source code of a compiled extension anyway.

Cython code looks very much like Python. Very likely, a Python programmer would 
understand the Cython code. Anyway, this is besides the point: even if it just 
benefits the author of the Cython code, it's already useful.

> it's not exactly an urgent issue.

I never proposed to make it a release blocker :-)
It's not urgent but it should still be fixed.

> Cython still needs to work around the issue for users of older Pythons.

No. Older versions already work because there is no ExtensionFileLoader. The 
changes in Python 3.x(?) actually broke this. Certainly in Python 2.7, those 
tracebacks work fine.

[issue32797] Tracebacks from Cython modules no longer work

[Paul Moore]

Paul Moore  added the comment:

As I noted on python-ideas, continuing to search along sys.path if the loader 
returns None seems to match what the linecache docs say. If the issue had been 
phrased as "the implementation of linecache doesn't follow the docs" then I'd 
say fine, that's a reasonable report of something that we should fix.

But Erik's points are valid - the fact that the documentation describes a 
certain behaviour doesn't mean that it can't be wrong - and the fact that 
no-one else has flagged up the discrepancy before now implies that it's a 
relatively rare case.

IMO, debating whether a None return means there's absolutely no chance of there 
being source is silly - the best the loader can say is that it can't provide 
source. But that doesn't prove anything.

On the other hand, what is Cython source code even doing on sys.path? The whole 
discussion here seems to be based on the premise that extension modules 
(machine code) will be shipped with source code that will get installed 
alongside the binary. That's not the case for C extensions, but appears to be 
for Cython. I sort of understand the benefit, but it does seem to be a practice 
peculiar to one scenario, and I'm not sure the standard library should deal 
with it. (There's a performance cost to that path search, and I'm struggling to 
see how a Python programmer would benefit from access to the source code of a 
compiled extension anyway).

So I think that *either* we should fix the docs to be clearer that the path 
search is only done if the loader is not present or returns None, *or* we 
should implement the path search when the loader returns None. But I don't see 
that there's a strong argument here yet for changing the code - after all, it 
appears that the current behaviour has been round since Python 3.3, so it's not 
exactly an urgent issue. And unless someone is arguing that the change get 
backported, Cython still needs to work around the issue for users of older 
Pythons.

[issue33394] the build of the shared modules is quiet/non-visible when GNU make gets passed macros

[Matthias Klose]

New submission from Matthias Klose :

the build of the shared modules is quiet/non-visible when GNU make gets passed 
macros. This is was introduced by the change to support BSD make.

GNU make adds all make macros passed on the command line to MAKEFLAGS. If one 
of these macros contains -s, the build of the extensions get quiet.

Also print out how setup.py is called.

[issue33392] pathlib .glob('*/') returns files as well as directories

[robbuckley]

New submission from robbuckley :

Path.cwd().glob('/*') seems to yield all files and folders in cwd, the same as 
.glob('*').

I believe that glob('*/') should yield only directories, and glob('*') all 
files and directories. this behaviour isnt documented one way or the other. But 
it would be consistent with glob.glob()

>>> x=list(range(1000))
>>> import sys
>>> sys.getsizeof(x)
9112
>>> del x[1:]
>>> sys.getsizeof(x)
96

[issue33012] Invalid function cast warnings with gcc 8 for METH_NOARGS

[Siddhesh Poyarekar]

Siddhesh Poyarekar  added the comment:

Yeah, there are multiple such uses that need wrappers to actually fix for gcc8, 
which will be released this week.  I think I'll have more time for some more 
patches in this vein this weekend.

[issue33012] Invalid function cast warnings with gcc 8 for METH_NOARGS

[STINNER Victor]

STINNER Victor  added the comment:

The commit 55edd0c185ad2d895b5d73e47d67049bc156b654 introduced a new warning:

It seems like a conversion to (unaryfunc) is needed when passing long_long as 
nb_int in long_as_number.

Thank you for the help.  My immediate goal for IDLE is to fix unicode problems, 
to the extent allowed by tk, before 3.7.0.

[issue33390] matmul @ operator precedence

Mark Dickinson  added the comment:

Gah! Forgot that my post would reset this issue to open. I'm going to close 
here, since this would be a sufficiently big and unlikely change that it's not 
going to happen without a python-ideas/python-dev discussion.

[issue33385] setdefault() with a single argument doesn't work for dbm.gdbm and dmb.ndbm objects

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Thank you Raymond. I hesitated to make a choose.

Ned, is it good to add a deprecation warning in setdefault() methods of the dbm 
classes when they called with a single argument in 3.7? Their current behavior 
(no-op or error) is not useful in any case.

[issue21474] Idle: updata fixwordbreaks() for unicode identifiers

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

> Do we still need this line in fixwordbreaks?

Yes. Loading word.tcl sets tcl_wordchars and tcl_nonwordchars. We should ensure 
that word.tcl is loaded and these variables are set before we change them.

[issue21474] Idle: updata fixwordbreaks() for unicode identifiers

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Now-closed duplicate #33386 reported that μ, 0x3bc, is not selected as part of 
identifiers when double clicking.  This prompted some research.

The 'Windows' style imitates the behavior of Command Prompt, which I presume is 
a carryover from DOS days.  PowerShell stuck with it, but Notepad, Notepad++, 
Microsoft Word, Firefox, Thunderbird, and ??? have not. I think Tcl should have 
switched long ago.  In any case, I will go with whatever the tcl re engine 
defines as word chars, the 'Motif' style', rather than attempt to write a giant 
re, which would have to change as characters are added.

Do we still need this line in fixwordbreaks?
tk.call('tcl_wordBreakAfter', 'a b', 0) # make sure word.tcl is loaded
I will leave it until you say we don't.

After patching, 'abcμμμdef' ('0x3bc'*3) is selected as one word instead of 
word, nonword, word.  'abc+efg' is still selected in 3 pieces, instead of the 1 
word seen by Command Prompt.

[issue33380] Update module attribute on namedtuple methods for introspection.

[pmpp]

pmpp  added the comment:

I see that as a good fix, obviously Point definition belongs to __main__ in the 
sample, like would any other subclass defined there eg if "some" class is 
defined in awe.py module :

>>> import awe
>>> class my(awe.some):pass
... 
>>> my.__module__
'__main__'

[issue33380] Update module attribute on namedtuple methods for introspection.

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Am not sure I can see any value in pushing the __module__ attribute down into 
the methods and think it is reasonable for them to report their origin as being 
in the collections module.

[issue33385] setdefault() with a single argument doesn't work for dbm.gdbm and dmb.ndbm objects

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Option 2 seems perfectly reasonable here as a way of preventing bugs (working, 
correct code wouldn't be using the existing default of None).

Option 1 is problematic because of the variance from Mutable Mapping, because 
breaking symmetry with get(), and because the change in behavior is implicit.
