[issue27173] Modern Unix key bindings for IDLE

[Terry J. Reedy]

Terry J. Reedy added the comment:

I don't understand 
>  idle_modern_unix_key_set3.patch effectively fixes [the bug].
That is the patch that generated the exception I posted.

I look forward to contributions to improving the dialog.  Redoing the font tab 
is #24776.  The highlight tab is #24781.  The latest mockups look like 
improvements to me, but we can discuss further.  (#24781 also has Mark's 
proposed refactoring of the dialog code, but I have not reviewed in detail.)  
There are numerous issues connected with key definitions.

Jelle, I think it would be safer to use "except Exception" here. "except

[issue27242] Make the docs for NotImplemented & NotImplementedError unambigous

[Emanuel Barry]

Emanuel Barry added the comment:

Added further notes to `NotImplemented` and `NotImplementedError` to clearly 
state the differences between the two. I also added some more details to 
`TypeError` - I'm amazed at how little was described for such a common 
exception!

Maybe I explained a bit too thoroughly in some parts, but I like to have 
everything unambigous and well explained.

I haven't yet spent the time to learn how to build documentation (Soon™), so 
I'm going off the existing docs, and I try to follow the style as closely as 
possible.

[issue5124] IDLE - pasting text doesn't delete selection

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I think it is better to fix this in all versions unconditionally.

This simple workaround is good enough for IDLE, but if add it as a part of 
Tkinter, it should be much more complex. I prefer to provide this as a recipe 
at http://code.activestate.com/recipes/langs/python/ .

[issue27127] Never have GET_ITER not followed by FOR_ITER

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

What if generate following code?

GET_ITER
JUMP_FORWARD L2
L1:
# ...
L2:
FOR_ITER L1

This saves one jump instruction per iteration.

Next, we can merge GET_ITER+JUMP_FORWARD in one FOR_BEGIN instruction for 
regular loops. Generators will start with JUMP_FORWARD.

[issue27127] Never have GET_ITER not followed by FOR_ITER

[Demur Rumed]

Demur Rumed added the comment:

Attached is a patch which fixes test_sys_settrace & test_pdb & test_trace. 
Still failing is test_genexps. I'm unsure the best way to fix this one:

1. Allow generator expressions to defer type errors about non iterables until 
the initial call to next

2. Create a TEST_ITER opcode entirely for generator expressions to eagerly throw

3. Generate instructions like
FOR_BEGIN, if empty, jump over generator & put an empty generator on the stack
-> CALL_FUNCTION 2, have generator produce code as LOAD_FAST 0, LOAD_FAST 1, 
, FOR_ITER repeat  (ie translate stack of FOR_BEGIN from before 
call as header of generator)

Empty generator can be created with 'LOAD_CONST (None,), FOR_BEGIN, POP' but it 
seems rather bad to have generators require 3 more opcodes around their 
creation than currently

[issue27173] Modern Unix key bindings for IDLE

[Terry J. Reedy]

Terry J. Reedy added the comment:

I looked at _set3 and it looks plausible and possibly complete other than 
testing.  I added something about testing customizations to #27099.  This 
applied cleanly to 3.6.  3.6 started, dialog opened, new key set selected, 
dialog closed, config-main.cfg looks good.  Open dialog, same as custom, close 
dialog, config-keys and config main changed as expected.  Open 3.5, open 
dialog, everything looks fine.

Now the problems.

1. To delete, one must select as current.  After deletion, config tries to 
reread the keyset just deleted.  This prints a warning to console for each item 
in the set, with message as to default used instead.   The same happens with 
deleting custom themes.  I may have noted this somewhere, but cannot find.

In any case, the solution for both problems is to either allow deletion of 
non-selected sets, and only such, or to switch to *something* before 
re-reading.  I open a new issue, #27245, for this.

2. More serious, the warnigs are followed by
Exception in Tkinter callback
Traceback (most recent call last):
  File "F:\Python\dev\35\lib\tkinter\__init__.py", line 1550, in __call__
return self.func(*args)

doit = lambda: self.bindedfuncs[triplet[2]][triplet[0]].remove(func)
ValueError: list.remove(x): x not in list

Hitting OK repeats warnings and traceback (the last line might have been a bit 
different the first time).  Only Cancel would close.

[issue27245] IDLE: Fix deletion of custom themes and key bindings

[Terry J. Reedy]

New submission from Terry J. Reedy:

Open IDLE by running from console or importing idlelib.idle in interactive 
Python window.  In the IDLE Preferences dialog, create a new custom theme or 
key set.  [Apply] or close with [OK].  Reopen, if necessary, select the new 
custom set as current, select Delete, and Apply or close.  IDLE will delete the 
set and then try to read it.  A warning message will appear in the 
console/interpreter for each item in the set that is had to replace with the 
default value.

IDLE should replace the deleted set with one of the builtins before reading, or 
even better, allow and require deletion of something that is not current.

Yury's proposal sounds good to me - I'll have time to do a proper review 
tomorrow (at a quick glance, my one suggestion is to move the if statement 
outside the example decorator, so the decorator is defined differently based on 
the Python version, rather than checking the version when called)

[issue5124] IDLE - pasting text doesn't delete selection

[Terry J. Reedy]

Terry J. Reedy added the comment:

I can't test but I looked at the patch.  It uses the new-to-me fact that bound 
'functions' can be tcl code in a string.  For me, root.bind_class('Text', 
'<>') returns the code string '\ntk_textPaste %W\n'.  Options for 
the patch:

0. Do nothing.
1. 3.6 as option (default TBD).
2. 3.6 as fixed change.
3. All versions as option (default TBD).
4. All versions as fixed change.

I have determined that adding new sections to config-main does not affect 
previous releases, so 1 and 3 are possible.  See the post I just made to #27099 
as to what is needed for new options.

For 1 and 3, there is the question of default - 'insert' versus 'replace', and 
for 3, whether it should be the same in all versions.  I don't think 'insert' 
and the option should stay around forever.

The question we need to think about is what would be best for beginners. The 
young but experienced Widows user, new to Linux, reported this to me as a bug 
that tripped her up a lot.

Serhiy, I think that this change, at least as an option, should be in tkinter, 
so as to make it more 'cross-platform'.  In the meantime, I will look at 
including this with the changes in #20799.

I am thinking about posting to python-ideas for other opinions on what to do in 
which package.

[issue27099] IDLE: turn builting extensions into regular modules

[Terry J. Reedy]

Terry J. Reedy added the comment:

The final paragraph of my initial post should have talked about config-main and 
features, rather than keys.

The following experiment indicates that adding new sections to config-main.def 
and customizations thereof to config-main.cfg should not be a problem. 

Add the following to config-main.cfg
[NewSection]
new = True

Open IDLE 2.7 from console (python, with import).
Open config dialog.
Change item.
Close with [OK]
confirm that change is written and new section is left alone.
Close IDLE.
Repeat with 3.5.

Old versions will not see new config-main.def, so that is not an issue.

Conclusion: adding a new section that old versions ignore is much safer then 
adding a new value for a current section that old versions do read and act 
on, and which may refer to something that does not exist.  (This was the 
problem with IDLE Dark theme and would be with Unix New keyset).

The remaining issues:

4. Finding a place on the dialog itself for new customization widgets. On Font, 
Theme, and General tabs, there is space available either now or with some 
changes.  The dialog can be enlarged if needed.

5. Adding the behind-the-scenes plumbing.  This is mostly straightforward.

6. Doing minimal refactoring to make better testing easier.
That would include being able to patch in a .idlerc directory or individual 
user files.  The files are small and could easily fit in memory as StringIOs.

I would like to be able to set user files, open config and idleConf, open 
config dialog, simulate user actions on the dialog, close, and check the effect 
on the files.

[issue27188] sqlite3 execute* methods return value not documented

[Dave Sawyer]

Dave Sawyer added the comment:

Updated optional parameters. Fixed executescript which takes a single 
parameter. The English is correct - one needs to looks at the verbs to be sure 
they match in tense and number. Like "He OPENS the fridge, GRABS the milk, and 
DRINKS it." This method CREATES a cursor, CALLS the method, and RETURNS the 
cursor.

[issue20210] Provide configure options to enable/disable Python modules and extensions

[Marc-Andre Lemburg]

Marc-Andre Lemburg added the comment:

Just found this ticket and apparently late to the game...

Some comments:

It is already possible to selectively build Python C extension modules in the 
stdlib via editing the Modules/Setup file and this is a lot better to maintain 
than a long list of configure options.

Martin's suggestion to add support for a *disabled* option would make this even 
easier. This would also complement the *static* and *shared* option we have for 
Modules/Setup to define modules to compile into the main executable rather than 
as shared module.

The only bit that's missing (if really needed), is to prevent setup.py from 
building modules not listed in Modules/Setup as shared libs. This could be had 
with a single configure option, e.g. --disable-setuppy-builds.

But all that said, I don't think, it's really necessary to cripple Python just 
to save some image space. As you can see with our eGenix PyRun runtime, it is 
possible to compress Python down to just a few MBs:

http://www.egenix.com/products/python/PyRun/

while still having most of the stdlib readily available.

__file__ could be None if __spec__.origin is None. The import machinery doesn't 
introspect on __file__ for anything, so it won't break import if __file__ has 
alternative values. In general, though, normal imports will set __file__ to a 
string.

Oh, this is tough.

How about we do this:

1. In 3.5.2 we start to support new behaviour. We raise 
PendingDeprecationWarning.  We update documentation and PEP 492.  The 
recommended way to write 3.5 code is to keep returning awaitables from 
__aiter__.  We can add a snippet of code for a compatibility decorator to the 
docs.

2. In 3.6 we start to raise DeprecationWarning.  The recommended way to write 
code for 3.6 & 3.7 is to return async iterators from __aiter__.

3. In 3.7 we remove support of the old behaviour.

It's a rather long & conservative process, but it will be

[issue27243] __aiter__ should return async iterator instead of awaitable

[Nick Coghlan]

Nick Coghlan added the comment:

Since the old behaviour is only deprecated with Yury's changes, rather than 
disallowed entirely, I think it makes sense to provide a 3.5.x version that 
also supports the new behaviour.

In addition to my docs comment above, the other thing I noticed in reviewing 
the patch is that the proposed tests don't currently check that we *don't* emit 
a deprecation warning for the newly permitted forward compatible cases that 
return an asynchronous iterator (rather than an awaitable) directly from 
__aiter__.

There are definitely some tests that exercise that path, so we could rely on 
the general principle of "the test suite shouldn't emit deprecation warnings", 
but we could also add some tests that specifically check that no warning is 
emitted in that case.

[issue26839] Python 3.5 running on Linux kernel 3.17+ can block at startup or on importing the random module on getrandom()

[Colm Buckley]

Colm Buckley added the comment:

@larry -

Thank you for joining in. I'm uploading a third version of the patch (against 
clean 3.5.1 source, with correct whitespace and a less confusing comment) which 
implements the following:

* configure.ac / pyconfig.h.in : looks for linux/random.h and sets 
HAVE_LINUX_RANDOM_H if present.

* random.c : calls getrandom() with the GRND_NONBLOCK flag; if that fails, fall 
back to reading /dev/urandom which will have insufficient entropy but will at 
least return some data.

I feel that there is no consistent way to signal to higher-level applications 
that the random data has sub-standard entropy; but that this at least preserves 
the expected semantics, and doesn't block on startup in the event of an 
uninitialized entropy pool.

[issue26839] Python 3.5 running on Linux kernel 3.17+ can block at startup or on importing the random module on getrandom()

[Larry Hastings]

Larry Hastings added the comment:

Speaking as the 3.5 RM, I suppose I have to have an opinion.  I don't think 
"Python now uses a better source of randomness to seed the random module at 
startup" is a major feature.  It's a nice-to-have, not a must-have.  And people 
who care about good randomness (e.g. people doing crypto with the random 
module) shouldn't be relying on the freebie initialization they get just by 
importing.

So I think changing the default is fine, especially if the new default is "seed 
from the entropy pool, but if it's empty failover to the not-as-good source of 
random bits".  If you think that's a bad move, please add your comments 
here--I'm willing to have my mind changed about this.

I'll remind you: the schedule says I tag 3.5.2 RC 1 this coming Saturday 
(almost exactly six days from now).  Naturally I'd prefer to make the release 
on time.

[issue27243] __aiter__ should return async iterator instead of awaitable

[Yury Selivanov]

New submission from Yury Selivanov:

There is a small flaw in PEP 492 design -- __aiter__ should not return an 
awaitable object that resolves to an asynchronous iterator. It should return an 
asynchronous iterator directly.

Let me explain this by showing some examples.

I've discovered this while working on a new asynchronous generators PEP.  Let's 
pretend that we have them already: if we have a 'yield' expression in an 'async 
def' function, the function becomes an "asynchronous generator function":

   async def foo():
  await bar()
  yield 1
  await baz()
  yield 2

   # foo -- is an `asynchronous generator function`
   # foo() -- is an `asynchronous generator`

If we iterate through "foo()", it will await on "bar()", yield "1", await on 
"baz()", and yield "2":

   >>> async for el in foo():
   ... print(el)
   1
   2

If we decide to have a class with an __aiter__ that is an async generator, we'd 
write something like this:

   class Foo:
  async def __aiter__(self):
  await bar()
  yield 1
  await baz()
  yield 2

However, with the current PEP 492 design, the above code would be invalid!  The 
interpreter expects __aiter__ to return a coroutine, not an async generator.

I'm still working on the PEP for async generators, targeting CPython 3.6.  And 
once it is ready, it might still be rejected or deferred.  But in any case, 
this PEP 492 flaw has to be fixed now, in 3.5.2 (since PEP 492 is provisional).

The attached patch fixes the __aiter__ in a backwards compatible way:

1. ceval/GET_AITER opcode calls the __aiter__ method.

2. If the returned object has an '__anext__' method, GET_AITER silently wraps 
it in an awaitable, which is equivalent to the following coroutine:

async def wrapper(aiter_result):
return aiter_result

3. If the returned object does not have an '__anext__' method, a 
DeprecationWarning is raised.

[issue27236] Add CHAINED_COMPARE_OP opcode

[Josh Rosenberg]

Josh Rosenberg added the comment:

It is a little funny though. I expect a more common test like:

if a < b < c: pass

to be unconditionally faster than the logically equivalent:

if a < b and b < c: pass

The only difference between the two should be that b is loaded only once, which 
should make the chained comparison either equivalent or faster. But thanks to 
the additional stack manipulations needed, in microbenchmarks, this isn't the 
case. I was just testing a couple simple cases in ipython (3.5, Linux, x64), 
and the chained comparison is actually slower when short-circuiting is involved:

%%timeit -r5 a, b, c = range(3, 0, -1)
if a < b < c: pass
1000 loops, best of 5: 33.7 ns per loop

%%timeit -r5 a, b, c = range(3, 0, -1)
if a < b and b < c: pass
1000 loops, best of 5: 25 ns per loop

or even without short-circuiting, but with the final test failing, chained 
loses (by a smaller margin):

%%timeit -r5 a, b, c = 0, 1, 0
if a < b < c: pass
1000 loops, best of 5: 42.5 ns per loop

%%timeit -r5 a, b, c = 0, 1, 0
if a < b and b < c: pass
1000 loops, best of 5: 39.3 ns per loop

The same pattern holds if a and c are replaced with constants, e.g. if 0 < b < 
2: (so only b is loaded by name). Yes, it's a small difference; when a, b, c 
are initialized from range(3), so all tests succeed, chained comparisons win, 
44.9 ns to 54.5 ns. But it seems kind of odd that the simplest case of a 
chained comparison is actually a pessimization in two of the three cases.

Not saying it's worth changing (I doubt chained comparisons occur in code 
enough to justify the tiny savings a dedicated op code could provide), but it's 
not something I'd reject out of hand.

[issue22558] Missing doc links to source code for Python-coded modules.

[Nathan Harold]

Nathan Harold added the comment:

I went over the sections I above called "Other/Smaller details" as addressed in 
mywork3.patch.  I think they look fine.  The patch applies seamlessly to both 
3.5 and 3.6.

For reference, since I noted them when I reviewed mywork2.patch last week, here 
are the packages at issue in the question about links to packages:

Package docs in which the patch in this issue adds a link to __init__.py: 
dbm.rst, email.rst, importlib.rst, json.rst, msilib.rst, tkinter.rst, 
unittest.rst, xml.dom.rst, xml.sax.rst

Package docs in which the patch in this issue adds a link to a directory: 
2to3.rst, email.mime.rst, idle.rst, multiprocessing.rst, sqlite3.rst, 
urllib.rst, venv.rst, xml.rst

Also, I noticed that asyncio.rst provides a precedent for linking to a source 
directory.  So both ways have been done before.

I think such warnings should be emitted at application level, similar to the

[issue26415] Fragmentation of the heap memory in the Python parser

[A. Skrobov]

A. Skrobov added the comment:

Now that #26526 landed (thanks to everybody involved!), I'm requesting a review 
on an updated version of my patch, which addresses the excessive memory 
consumption by the parser.

The description of my original patch still applies:

> The attached patch for the parser reduces "Maximum resident set size 
> (kbytes)" threefold, for the degenerate example of 'import ast; 
> ast.parse("0,"*100, mode="eval")', by eliminating many CST nodes that 
> have a single child.
>
> According to the comment in Parser/node.c -- "89% of PyObject_REALLOC calls 
> in PyNode_AddChild passed 1 for the size" -- the memory saving should be 
> generally applicable, and not limited just to this degenerate case.

> I've now tried it with "perf.py -r -m", and the memory savings are as follows:
> ...
> on these benchmarks, the saving is not threefold, of course; but still quite 
> substantial (up to 30%).

My new patch updates Modules/parsermodule.c to accept such "compressed" nodes, 
so that everything still builds cleanly and passes the tests.

[issue27231] Support the fspath protocol in the posixpath module

[Jelle Zijlstra]

Jelle Zijlstra added the comment:

I wrote the patch assuming that the error messages would be changed in 
accordance with issue27232. Let's put this on hold until that is resolved.

[issue27232] os.fspath() should not use repr() on error

[Jelle Zijlstra]

Jelle Zijlstra added the comment:

No, that issue just adds the address to the repr() of types. It is not normal 
to use repr for type objects in error messages:

>>> int(None)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: int() argument must be a string, a bytes-like object or a number, 
not 'NoneType'

[issue27240] 'UnstructuredTokenList' object has no attribute '_fold_as_ew'

[Leblond Emmanuel]

New submission from Leblond Emmanuel:

The folding code for email headers crashes whenever it hits line 
_header_value_parser.py:432 given it try to call method `_fold_as_ew`.

```

AttributeError: 'UnstructuredTokenList' object has no attribute '_fold_as_ew'
> /usr/lib/python3.5/email/_header_value_parser.py(432)_fold()
-> part._fold_as_ew(folded)
```

Given folding depends a lot on the processed value, this bug only trigger in 
very specific encoded headers (I've try to reproduce this bug with various 
values but only the one which originally made me find the bug worked so far).

I've isolated the bug into a simple test case (see enclosed file).

It seems this part of the code has been rewritten between Python2 and 3 (the 
file _header_value_parser.py doesn't exists in Python2). So unsurprisingly the 
bug doesn't trigger in Python2.

Replacing `part._fold_as_ew(folded)` by `part._fold(folded)` seems to fix the 
bug, but given my poor knowledge of this code, this fix probably produce 
unwanted behaviors.

[issue27235] Heap overflow occurred due to the int overflow (Python-2.7.11/Modules/posixmodule.c)

[Xiang Zhang]

Xiang Zhang added the comment:

I am confused why this could happen. On x86 platform, you can not even create a 
string of size 0x. On x64 platform, I don't think strlen(s) + 3 can 
lead to overflow where s is of size Py_ssize_t.

[issue27232] os.fspath() should not use repr() on error

[SilentGhost]

SilentGhost added the comment:

This is behaviour introduced by issue 25548, it would make sense to me to 
discuss this problem there if you think it's necessary. repr in error messages 
has been a standard approach in Python for a very long time, however.
