[issue25211] Error message formatting errors in int object unit-test script

[s-wakaba]

New submission from s-wakaba:

I've found some parts there are illegal message formatting in int object unit 
test script "Lib/test/test_long.py" when hacking the interpreter.

because they were an easy problem, I already fixed them to promote my work.
Therefore, the patch has been attacked.

thanks

Seems like the right fix would be to change site.py to read it using UTF-8.

[issue25194] Register of Financial Interests for core contributors

[Nick Coghlan]

Nick Coghlan added the comment:

Ezio's right I ended up mixing together a few different objectives here, which 
is an artifact of how the idea came about:

* my starting point was wanting a list of folks that already have commit access 
(and hence are demonstrably familiar to the core development community) that 
the PSF can either contract with directly for work on the toolchain (and 
perhaps for devoting time to the tracker patch backlog), or else refer 
companies to. At the moment we do this based on personal knowledge, which means 
there are going to be missed opportunities to make connections with folks the 
current Board of Directors don't know personally.

* in the ensuing discussion, I realised the "we're all volunteers here" 
disclaimer isn't true at the moment, and is unlikely to ever be true again, and 
that's something that would be good to disclose to help folks understand the 
sustaining engineering model that has emerged around CPython

The draft patch ended up being framed as the latter, while still covering the 
former, which I agree is confusing.

As a result, I like the idea of making the page title "Motivations and 
Affiliations" to focus on the "Why are we here?" aspect.

At the end, we can then have a section "Availability for PSF Referrals" and ask 
core developers that are potentially able to take on contract and freelance 
work to let the PSF Board know. We can then maintain that list in confidence, 
rather than requiring people to broadcast their availability for contract work 
to the entire internet.

[issue24870] Optimize coding with surrogateescape and surrogatepass error handlers

[STINNER Victor]

STINNER Victor added the comment:

I pushed utf8.patch by mistake :-/ The advantage is that buildbots found bugs. 
Attached utf8-2.patch fixed bugs.

The bug was how the "s" variable was set in the error handler. It's now set 
with:

   s = starts + endinpos;

Bugs found by the buildbots:

[issue25211] Error message formatting errors in int object unit-test script

[Martin Panter]

Martin Panter added the comment:

Thanks for the patch, it looks correct. The Frm class takes a variable number 
of *args, and then returns “format % args”. It should at least be applied to 
the 2.7 branch.

For 3.4+, perhaps we can eliminate the need for the Frm class altogether, by 
using TestCase.subTest():

def check_bitop_identities_1(self, x):
eq = self.assertEqual
with self.subTest(x=x):
eq(x & 0, 0)
...
for n in range(2*SHIFT):
p2 = 2 ** n
with self.subTest(n=n, p2=p2):
eq(x << n >> n, x)
...
eq(x & -p2, x & ~(p2 - 1))

[issue25210] Special-case NoneType() in do_richcompare()

[STINNER Victor]

STINNER Victor added the comment:

> TypeError: unorderable types: int() < NoneType()

The error message looks good to me: NoneType is the type of the None singleton:

>>> type(None)

>>> x=type(None)()
>>> x is None
True

Do you propose to use the message "TypeError: unorderable types: int() < None"? 
This message looks wrong to me, None is not a type.

The strange thing is the trailing parenthesis!? Why not "int < NoneType"?

[issue25159] Regression in time to import a module

[STINNER Victor]

STINNER Victor added the comment:

I tested on Linux.

(1) for i in `seq 5`; do ./python -I -m timeit -n1 -r1 -s "import sys; 
sys.modules.clear()" -- "import enum"; done

(shortest timing)

Python 3.4: 6.93 msec
Python 3.6: 7.05 msec (+2%)


(2) for i in `seq 5`; do ./python -I -m timeit "import enum"; done

Python 3.4: 0.331 usec
Python 3.6: 0.341 usec (+%3)

These numbers are nanoseconds, it's too short to run a real benchmark.


(3) for i in `seq 5`; do ./python -I -m timeit -n1 -r1 "import enum"; done

Python 3.4: 801 usec
Python 3.6: 774 usec (-3%)


Sorry, I don't see major differences like you showed. Can you explain exactly 
how to reproduce them? Exact Python version? OS?

I used the development branches (branch 3.4 and branch default).

> Hum, does it make sense to enable LTO without PGO?

Probably not.

By the way, I now have a small ARM system to play with, and there the gain of 
LTO+PGO over PGO alone is around 10%.

Also note LTO can make compilation times much longer (it's the linking step 
actually, which can take minutes).

[Ezio Melotti]

Ezio Melotti added the comment:

Thanks for your contribution, however double spaces after a full stop should be 
kept, since they are intentional (they make the .rst source more readable).  
Your patch also seems to include other instances that are not after a full 
stop.  In theory those could be kept, but I'm not sure if it's worth spending 
time preparing and applying a new patch.

In the following example, the double space between "is" and "an" could be fixed

"This" is OK and should be kept:

This is  an example.  This too.

[issue25212] Remove the double spaces in the C-API Intro

[STINNER Victor]

STINNER Victor added the comment:

The vim editor *adds* two spaces between a full stop and the beginning of a new 
sentence. As a french, I was always distributed by this, but it's correct in 
english :-) As Ezio wrote, it may even be better to have two spaces than one, 
for readability.

Well well well, this issue is really border line because users don't read the 
.rst files but the HTML output which uses a single space.

Seriously, why really cares? Just close the issue as WONTFIX and try to enhance 
the doc differently ;-)

[issue25213] Regression: Python 3.5.0 shutil.copy2 doesn't raise PermissionError on Windows 7

[Nick Evans]

New submission from Nick Evans:

Python 3.5.0 shutil.copy2 doesn't raise PermissionError when it does not have 
permission to copy a file (tested on Windows 7):

C:\Users\X\Desktop>C:\Users\X\AppData\Local\Programs\Python\Python35-32\python.exe
Python 3.5.0 (v3.5.0:374f501f4567, Sep 13 2015, 02:16:59) [MSC v.1900 32 bit

Type "help", "copyright", "credits" or "license" for more information.
>>> import shutil
>>> shutil.copy2("test.txt", "/")
'/test.txt'
>>> shutil.copy2("test.txt", "C:\\")
'C:\\test.txt'

NB: The file is not copied.

Python 3.4.3 does raise PermissionError:

[issue25214] asyncio ssl transport regression

[Andrew Svetlov]

New submission from Andrew Svetlov:

Before using SSL BIO (which is great itself BTW) I has a way to access peers 
certificate by `ssl_transp.get_extra_info('socket').getpeercert()` call.

Now socket is a regular socket without `.getpeercert()` method.
I use hack like `ssl_transp._ssl_protocol._sslpipe.ssl_object.getpeercert()` as 
workaround but really interesting in the proper way to do this using public API 
only.

I suggest adding 'ssl_object' key to `ssl_proto` for BIO-based SSL.

Thoughts?

P.S.
See aiohttp commit for workaround bugfix: 
https://github.com/KeepSafe/aiohttp/commit/e286d4f9fb1993de2438bdca40712cf1660faf9e

[issue25215] Simple extension to iter(): iter() returns empty generator

[Jurjen N.E. Bos]

New submission from Jurjen N.E. Bos:

When looking for a "neat" way to create an empty generator, I saw on 
stackOverflow that the crowd wasn't sure what was the "least ugly" way to do it.
Proposals where:
def emptyIter(): return; yield
or
def emptyIter(): return iter([])

Then it struck me that a trivial extension to the iter() built-in would be to 
allow to call it without arguments, thus giving a simple to understand empty 
iterator, and allowing:
def emptyIter(): return iter()
(And, of course, this function would not need to exist in any reasonable 
program in that case.)

The implementation would be trivial, I assume.

[issue25206] PEP 498: Minor mistakes/outdateness

[Eric V. Smith]

Eric V. Smith added the comment:

Thanks for the feedback.

On the 
f"{expr3!s}" → format(str(expr3))
issue, I'm trying to show the 1 argument version of format (which is what the 
code generator actually calls). Although I realize that's not a great example, 
since the string conversion is implicit in format(). Maybe I'll have the !r 
example be the 1 argument format() call.

I'll fix the exceptions, eventually. But I don't want the PEP to become a exact 
specification of what the exception text will actually be.

On this one:
f'x={!x}'
I'll probably change it to be an error with the empty expression, not with the 
invalid conversion character.

[issue25215] Simple extension to iter(): iter() returns empty generator

[Raymond Hettinger]

Raymond Hettinger added the comment:

I'm not sure that python needs a neater way to make an empty generator.  It 
isn't a common use case and there isn't anything wrong with iter([]).

There are downsides to expanding an API.  It creates yet another thing to learn 
and remember.  Even now, few developers know about the two-argument form of 
iter().

[issue25216] Warnings stacklevel frames to skip

[Jim Jewett]

New submission from Jim Jewett:

warnings.warn(stacklevel=2) is a longstanding idiom.

It broke in 3.3 because python itself added some additional infrastructure 
frames in between; now stacklevel should be 8 or 10 in some releases.

issue24305 adds a workaround for 3.5, to ignore internal frames -- defined as 
those which contain both 'importlib' and '_bootstrap' in filename.

I would prefer to see a supported hook, so that either the caller or the 
program setup could list other modules or packages to ignore when counting 
frames.  That way, I could write

mycall(otherlib(foo))

and otherlib could ensure that the warning pointed to mycall, rather than to 
something internal to otherlib, even if otherlib were refactored to a different 
stack depth.

Ignoring just the import machinery would of course be a good default.

[issue25215] Simple extension to iter(): iter() returns empty generator

[Brett Cannon]

Brett Cannon added the comment:

I agree with Raymond. Allowing a non-argument iter() runs the risk of someone 
messing up and forgetting the arguments and yet having no error that they did 
so. And considering how easy it is to get an iterator of an empty list or tuple 
I don't see a benefit.

Thanks for the suggestion, Jurjen, but I'm closing this as rejected.

[issue25177] OverflowError in statistics.mean when summing large floats

[Steven D'Aprano]

Steven D'Aprano added the comment:

Bar, thanks for the time you put into diagnosing this error, it is 
definitely a bug. The intention is for mean([huge, huge]) to return 
huge, not raise OverflowError.

I'm reluctant to say that mean() will *never* raise OverflowError, but 
it certainly shouldn't do so for this case if it can be avoided. I think 
Mark's diagnosis is probably correct that refactoring the code will fix 
this.

[issue25209] Append space after completed keywords

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Good catch Martin. Indeed, "pass", "break" and "continue" don't need a space, 
and "True", "False" and "None" need a space only in rare cases like "None in 
collection". Some keywords ("else", "finally", "try") need a colon. But while 
"return" and "lambda" not always need a space, I think that needing a space is 
more common case, and in any case the redundant space doesn't make a harm.

Here is revised patch that doesn't add a space in some cases and instead adds a 
colon in some cases.

[issue25205] setattr accepts invalid identifiers

[W deW]

W deW added the comment:

Thanks for the ref to issue14029. I think I see how it works. As long as the 
object's __dict__ accepts the attributeName as a key, it needs not be a valid 
string nor a string at all. Though the latter *is* checked for, and that in 
turn can be circumvented by adding the attribute to the __dict__ directly. An 
object can be made attribute to itself.

However, the documentation falls short here. So far, I haven't found where it 
defines "attribute". Is there any point in defining an attribute that cannot be 
addressed as an attribute if the parser doesn't allow it?

It seems to me that in order to catch programing errors early, the default 
behaviour should include checking the valid syntax of the attribute's name.

[issue25213] Regression: Python 3.5.0 shutil.copy2 doesn't raise PermissionError on Windows 7

In the 32-bit version, creating a file in the system root directory gets

shutil.copy2.

You can verify in the task manager's details tab that UAC Virtualization is 
enabled for 32-bit python.exe and disabled for 64-bit python.exe. The problem 
is that the manifest is missing the requestedExecutionLevel, which should be 
present and set to "asInvoker". This is discussed in the MSDN article [New UAC 
Technologies for Windows Vista][1].

[issue25217] Method cache can crash at shutdown in _PyType_Lookup

[Antoine Pitrou]

New submission from Antoine Pitrou:

In the following gdb backtrace you'll see that if Python code is executed from 
the PyInterpreterState_Clear() step in Py_Finalize() (apparently when clearing 
the builtins), _PyType_Lookup() can be executed and crash on a NULL entry in 
the method cache.

Note the reason this happens is that we set a weakref callback on the global 
print() function, and for some reason the weakref is able to survive longer 
than the global print() function. We don't have the crash on previous versions 
of Python (< 3.5).

Here is the backtrace:

[issue9051] Improve pickle format for timezone aware datetime instances

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

For stability it is better to use public name 'timezone.utc' instead of '_utc'. 
Dotted names now are supported with all protocols.

> but there is still room for improvement:

Don't worry about this. When you pickle a number of datetime objects with the 
same timezone, the timezone is pickled only once and for all other datetime 
objects only a reference is used.

[issue24295] Backport of #17086 causes regression in setup.py

[Moritz Sichert]

No this isn't an issue in Python 3.5. It was caused by the backport that was 
diffed against an older version that didn't include 7955d769fdf5 and thus

[issue25205] setattr accepts invalid identifiers

[Martin Panter]

Martin Panter added the comment:

Eryksun: If you mean tagging the bug report, I think we usually tag all the 
applicable open branches that are due for another release.

I’m not sure anything needs to be documented regarding setattr(). At best it is 
an implementation detail that should not be relied on, although making the 
implementation stricter could be a compatibility problem.

There are other places where troublesome names are allowed. One that caught my 
eye recently is os.sendfile(in=..., ...) is a syntax error, but you can still 
pass the “in” keyword via os.sendfile(**{"in": ...}, ...).

“Else” doesn’t always use a colon. Consider “1 if x else 2”. Again, if Python

[issue25124] No single .msi available for 3.5 release

[Steve Dower]

Steve Dower added the comment:

The decision cannot reasonably be reversed now - this sort of passionate 
feedback was really needed during the alphas to have any impact. I'm sorry you 
didn't feel the need to participate in Python's development, as this extra 
feedback would have been useful.

For most users who are installing Python for themselves, the bundle launcher 
provides a much better experience. As well as CRT detection, it also allows 
true per-user installation as well as decoupling tasks such as precompiling 
.pyc files from installing components and enabling the web installers. There is 
also a more reliable upgrade mechanism that retains previous settings and the 
launcher is now correctly reference counted (though there will be conflicts 
with the 2.7 and 3.4 installer...).

After discussions at PyCon US in April, I chose to make the per-user 
installation the default as it best fits the user segment we (as a development 
team) are most concerned about. Administrators who are deploying across a 
network do now need to work harder than before, which we considered a fair 
tradeoff for non-admin users to be able to install and use Python.

If you much prefer MSIs, you can pass the /layout option to the wrapper and 
obtain the raw MSIs and install them individually (passing 
"TARGETPATH=location" as a property). However, I think the documentation for 
the launcher options (https://docs.python.org/3.5/using/windows.html) is much 
better than anything we had in the past (I had nothing to do with the old 
installer, but had to regularly decompile it to diagnose installation issues).

So thankyou for the feedback, but on balance between administrators and 
individual users we've decided to help save individual users from having to 
read documentation, at the expense of needing administrators to refer to the 
instructions to do automated installation.

Arguably it's because of the platforms that don't reliably set errno. (I don't

now. If someone else wants to do it and deal with the fallout they're welcome.)

[issue25085] Windows x86-64 embeddable zip file contains test directorys

[Steve Dower]

Steve Dower added the comment:

True, those files aren't needed in the embeddable distro.

Terry - you're right, if someone chooses to install Tcl/Tk/idle then they'll 
get the tests for them as well, regardless of their test suite selection. Since 
we're not really talking about a lot of files, I'd rather leave them this way 
(which I think is what you're also suggesting?) than deal with the 
cross-installer dependencies that would exist otherwise.

[issue25112] Windows installer assigns non-existent icons to Python file types

[Steve Dower]

Steve Dower added the comment:

The file associations are actually part of the launcher, which *technically* is 
independent of the Python install it is bundled with. So it doesn't have any 
references to the Python install directory, and double-clicking Python files 
with shebang lines will work properly.

For 3.5.1 I'm considering making the launcher an independent uninstall item (in 
response to another issue), so if you install 3.5.1 and then remove it, you can 
keep the launcher. For this to work, it has to be independent of the main 
install, so it can't refer to the DLLs directory.

[issue25148] Windows registry PythonCore key changed inconsistent with other releases

[Steve Dower]

Steve Dower added the comment:

It was changed to be consistent with the PEP 397 launcher (and the launcher was 
actually updated to match the registry key directly, rather than special-casing 
the "-32" suffix).

The original naming ("3.5") can't be used because you can't simultaneously 
install 32-bit and 64-bit per-user Pythons with the same key name. (Previously 
it would "work", but you couldn't find both of them through the registry. Now, 
because of other changes, it will have more serious issues.)

Changing to "3.5-64" and "3.5-32" and not use "3.5" anymore was inconsistent 
with the launcher, but that's a fairly weak reason. There just didn't seem to 
be a stronger reason to change.

(I don't consider this a bug, so I'm closing, but if Barry or someone else 
wants to argue that it should be changed then I'm willing to consider it for 
3.6. I don't think changing it for 3.5.1 is a good move at this point.)

[issue15347] IDLE - does not close if the debugger was active

[Mark Roseman]

Mark Roseman added the comment:

Figured out the cause of this hang, it was to do with the nested event loops.

It turns out that mainloop() really should just be for the mainloop. Or at 
least quit() should only be used to quit the outer loop, as it relies on 
setting a static variable, so is not reentrant, i.e. does not handle nested 
event loops.

I changed the nested loop to use a different mechanism to start the nested 
event loop (vwait, which waits for a tcl variable to be set) and terminate the 
nested loop (setting that variable). Have attached fix-nested-mainloop.patch.

Fixes the problem here, and in #15348, and another case I was using (start, 
enable debugger, open module, run module, quit).

The one in #24455 is something different, I'll look into it.

[issue17942] IDLE Debugger: Improve GUI

[Mark Roseman]

Mark Roseman added the comment:

Have attached debugger-ui.patch, which greatly updates the user interface for 
the existing debugger.  

This also relies on some images that should be downloaded and unpacked into the 
'Icons' directory: http://www.tkdocs.com/images/debugicons.zip

Summary of changes:
 * works with both Tk 8.4 and 8.5+
 * paned window separates left and right, allowing adjusting relative sizes
 * on left, toolbar with graphical/text buttons, plus message, and stack
 * on right, local and global variables of selected stack frame
 * running program can be interrupted via 'stop' button
 * stack and variables use listbox (8.4) or tree (with resizable columns)
 * removed locals, globals, and stack 'view' options
 * source option changed to auto-open windows to see source
 * can always view source by double-clicking or context menu in stack
 * full value of variable can be seen via tooltip in variable list
 
In future, this will also replace the 'stack viewer' feature for displaying
exceptions, but this has not yet been integrated.

[issue25125] "Edit with IDLE" does not work for shortcuts

[Steve Dower]

Steve Dower added the comment:

Can you try executing the following command (fix the paths as necessary, but 
leave all the quotes where they are):

"C:\Program Files (x86)\Python 3.5\python.exe" -m idlelib "C:\test.py"

That's what should be launched by the menu, with a minor change to use 
python.exe instead of pythonw.exe to show up any errors you are hitting.

I couldn't reproduce the issue on Windows 10, but when I'm back at work I'll 
try with some other OS versions.

Done. As this is (meant to be) a purely informational/diagnostic module, seems 
like a good idea to fix every version we're supporting in any way.

[issue25117] Windows installer: precompiling stdlib fails with missing DLL errors

[Steve Dower]

Steve Dower added the comment:

The problem here is probably that installing the CRT update required a restart 
(see the line below from the log), but we didn't interrupt installation to make 
you restart before continuing.

>From the first log file:

[0A68:0EC8][2015-09-14T05:54:24]i319: Applied execute package: 
crt_14.0_v6.2_x64, result: 0x0, restart: Required


Handling this nicely could be some work. We would want to force the restart 
immediately if the user is installing pip or precompiling the stdlib, but 
otherwise they can finish installation and then restart. I'll try and look into 
this soon, but I don't think it needs to hold up a 3.5.1.

[issue25144] 3.5 Win install fails with "TARGETDIR"

[Steve Dower]

Steve Dower added the comment:

Well, I made this happen once, but not a second time. That's better than most 
setup issues I get to deal with :)

Still working on it - will post when I figure it out.
