Larry Hastings added the comment:

You wait until the day of release for 3.5.0 final, then create a "release 
blocker" because some items in the What's New documentation aren't 
lexographically sorted?

We tagged the release yesterday.  The installers are already built.  I am not 
holding up the release for this.

Serhiy Storchaka added the comment:

Sorry, but I thought that such issue already exist.

Yury and Elvis made a lot of changes in What's New in few last days and 
continue to edit it. Are these changes included in 3.5.0 final? Without their 
What's New just isn't ready.

[issue25087] Type variable substitution in type instances

[Stefan Krah]

New submission from Stefan Krah:

If a type scheme is instantiated, should the type variables in the
class body be substituted?  This is an example (typed by hand on
a locked down Windows machine, may contain errors):


alpha = TypeVar('alpha')
beta = TypeVar('beta')

class ABTuple(Generic[alpha, beta]):
def __init__(self, a : alpha, b : beta):
self.value = (a, b)

get_type_hints(ABTuple.__init__)
 ==> {'b': ~beta, 'a': ~alpha}


IntIntTuple = ABTuple[int, int]

IntIntTuple
 ==> __main__.ABTuple[int, int]

get_type_hints(IntIntTuple.__init__)
{'b': ~beta, 'a': ~alpha}
  ^^  ^^


Since the type has been specialized, these should ideally be 'int'.

Larry, it looks like the "Detailed Release Information" link on the release 
page still points to rc3, which is a 404 now.

Also, there doesn't seem to be a link to the "What's new" document, only a

Larry,

Please rebuild the documentation, we've pushed the last round of edits in 
746add37495c.

Also, could you please merge 3.5 into default -- I don't know how to resolve 
some conflicts after your 3.5.0 -> 3.5 merge.

> I could add a "What's New" link somewhere.

Thanks for adding it! Can we make it a bit more prominent by moving it to the 
top of the page?  PEP links are important, but what's new is more digestible.

Stefan, I've added a link to your package.

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

[Wolfgang Langner]

New submission from Wolfgang Langner:

The Windows x86-64 embeddable zip file (and possible the one for 32bit)
includes some unnecessary test folders in python35.zip with test scripts.

python35.zip\distutils\tests\
python35.zip\unittest\test\
python35.zip\lib2to3\tests\
python35.zip\ctypes\test\
python35.zip\sqlite3\test\

Python Version 3.5 rc4

This is only a minor issue, because it affects only size not functionality.

[issue25086] Windows x86-64 embeddable zip file, lot of big EXE files in distuils

[Wolfgang Langner]

New submission from Wolfgang Langner:

In the Windows x86-64 embeddable zip file in
python35.zip\distutils\command\
are a lot of big EXE files. Possible during build for different
VC compilers.

I don't know the exact structure but thing there should only be EXE's
for the actual used compiler to build Python.

But there are:

wininst-10.0-amd64.exe
wininst-10.0.exe
wininst-14.0-amd64.exe
wininst-14.0.exe
wininst-6.0.exe
wininst-7.1.exe
wininst-8.0.exe
wininst-9.0-amd64.exe
wininst-9.0.exe

These files are really big, and some or all? possible not needed for
and embeddable zip distributed Python.

[issue25084] remove semi-busy loop in py2.7 threading.Condition.wait(timeout=x)

[Flavio Grossi]

New submission from Flavio Grossi:

threading.Condition.wait(timeout=x) is implemented in python 2  as a semi-busy 
loop which causes cpu wakeups and unexpected cpu use.

I think this is somewhat problematic since it causes problems in all modules 
which use that method, such as Queue.get() when used with a timeout.

This issue has been reported and "fixed" in red hat based distributions in a 
way which i find problematic, as detailed here:
https://bugzilla.redhat.com/show_bug.cgi?id=1230802

The attached patch backports the following change from py3 to fix the problem:

Larry Hastings added the comment:

The "Detailed Release Information" link is correct.  You probably just have an 
old cached copy of something.

I could add a "What's New" link somewhere.

Though both of these things are interesting, neither of them is relevant to 
this issue.  Maybe you could jump on IRC and report them in real time?

Good catch.  Both Elvis and I are going to do a final thorough pass over the 
whatsnew to fix hiccups like this one.  In no way this should be a release 
blocker.

I'd say it's in a ready shape.  We've spent tons of time refining it, syncing 
NEWS items first, looking for undocumented changes in commits without NEWS 
updates, syncing docs by versionadded/changed (both ways), etc.  I'm fairly 
confident that 99% of changes are now documented.  We'll fix the remaining 
typos/formatting issues in a few hours.

Thanks for doing that, Larry!

[issue25061] Add native enum support for argparse

[paul j3]

paul j3 added the comment:

I'm not quite sure what you mean by 'the enum type to be stored directly'.

With my type function, the string input is converted to an enum object and that 
is stored in the Namespace.  You can't be any more direct than that.

Or are you thinking that `argparse` has some catalog of 'types' that it uses to 
check for value validity and conversion?  There isn't such a collection.  The 
value of the 'type' parameter has to be a callable.  (There is a registry 
mechanism, but that just maps strings on to callables.)

My suggestion does not provide help, but that isn't hard to write that for 
yourself.  A help parameter like:

help='Enum: {%s}'%','.join([t.name for t in CustomEnumType])

would display:

usage: ipython3 [-h] [-p P]

optional arguments:
  -h, --help  show this help message and exit
  -p PEnum: {VAL1,VAL2,VAL3}

For really long lists you could write a multiline help and display it with a 
RAW formatter.

I wouldn't use 'choices' with a type function like this.  The type function 
takes care of all the necessary testing and error messaging.  As you write, 
displaying the enum values would just be confusing.


If we define a dictionary wrapper for the enum class, the use of 'choices' 
might not seem so hacky:

 enumDict = {t.name.lower():t for t in CustomEnumType}
 parser.add_argument("-q", default="val1", choices=enumDict)

 parser.print_help()

producing:

usage: ipython3 [-h] [-p P] [-q {val1,val3,val2}]

optional arguments:
  -h, --help   show this help message and exit
  -p P Enum: {VAL1,VAL2,VAL3}
  -q {val1,val3,val2}

The keys of a 'choices' dictionary are used automatically in the usage and 
help.  That's nice when there are a few choices, but not so good when there are 
many.  Those problems have been discussed in other bug issues.

This dictionary can be used just like your code to convert the Namespace string 
to an enum object:

In [57]: parser.parse_args([])
Out[57]: Namespace(p=, q='val1')
In [58]: enumDict[_.q]
Out[58]: 

And of course 'choices' handles the error listing as well - a plus or minus:

In [59]: parser.parse_args(['-q','test'])
usage: ipython3 [-h] [-p P] [-q {val1,val3,val2}]
ipython3: error: argument -q: invalid choice: 'test' (choose from 'val1', 
'val3', 'val2')
...

If we are going add anything to streamline the handling of 'enums', it should 
also streamline the handling of any mapping.  The main thing that 'enums' adds 
to Python is a uniqueness constraint - which is an insignificant issue in the 
argparse context.  My custom type function would work just as well with a 
dictionary.  And a dictionary would allow the use of aliases, as well as the 
upper/lower tweaking.

[issue25088] scipy (0.16.0) install fails on 3.5

[Carol Willing]

Carol Willing added the comment:

I am unable to pip install scipy, numpy, or pandas using 3.5.0 on OS X 10.10.4.

After installing Python 3.5 using the installer downloaded from Python.org 
page, I created a virtualenv using `pyvenv myscipy` and activated with `source 
myscipy\bin\activate`. `python -V` returns 3.5.0.

`pip install scipy` succeeds in `Collecting scipy` and downloading 100% of 
file. It hangs after that indication for 1m 21s with no warnings or errors. 
Cancelled the operation. I tried with scipy, numpy, pandas with no success. I 
also tried `python -m pip install scipy==0.16` and it also stalled with no 
warning or errors.

`pip search` and `pip install flask` worked fine in the 3.5 virtualenv.

[issue25063] shutil.copyfileobj should internally use os.sendfile when possible

[desbma]

desbma added the comment:

If I understand you correctly, a naive implementation like this:

use_chunk_copy = False
try:
  fdsrc = fsrc.fileno()
  fddst = fdst.fileno()
except OSError:
  # fallback on current chunk based Python copy
  use_chunk_copy = True
else:
  # we have 2 fd, try sendfile
  try:
os.sendfile(fdsrc, fddst)
  except AttributeError:
# sendfile not available
use_chunk_copy = True
if use_chunk_copy:
  # use current Python based chunk copy

...would not work because some file like objects expose fileno(), even though 
it does not accurately represent the file because they wrap it to add special 
behavior (like GzipFile).

I don't understand, if they alter the file behavior, why do they expose 
fileno()?

[issue25088] scipy (0.16.0) install fails on 3.5

[Ned Deily]

Ned Deily added the comment:

For 3.4 and 2.7, the SciPy and matplotlib projects supply pre-compiled wheels 
for their distributions.  As of this moment, they haven't yet updated their 
PyPI entries with 3.5 wheels (.whl files).  Until they do, pip would fall back 
to trying to build them from source, which as Carol points out, will likely 
require installing additional non-Apple build tools, like gfortran.  Suggest 
you check on the mailing lists or other support forums for the SciPy and 
matplotlib projects to see when each expects to have OS X wheels available for 
3.5. I'd guess it won't be long since both are popular downloads.

[issue25061] Add native enum support for argparse

[desbma]

desbma added the comment:

I would like the enum type to be stored directly.

With your approach, the user does not know what are the possible choices, until 
he/she tries a invalid value and get the exception. If I pass the enum type to 
the choice parameter, the help message is not very user friendly 
(""...) and does not accurately represent possible 
input strings.

Anyway, my first example snippet works and does what I need, but it feels a bit 
like a hack.
In my opinion this is a classic use case for enums, that should be handled more 
naturally by the argparse module.

[issue25088] scipy (0.16.0) install fails on 3.5

[Carol Willing]

Carol Willing added the comment:

Naveen, I was able to resolve this problem for installation by installing 
gfortran using the instructions here: http://hpc.sourceforge.net/


After gfortran is successfully installed, I was able to ``pip install scipy 
-v`` the libraries that depend on gfortran. It did take 8m 39s to execute the 
install of scipy which is why I used the -v (verbose) option so that I could 
see that it was still working.

It would be good for numpy and scipy to indicate more clearly the absence or 
inability to find gfortran with a more obvious error message.

My recommendation is to close this issue if you are able to successfully 
install.

[Martin Panter]

Martin Panter added the comment:

I don’t know the exact reasoning, but fileno() could be useful for other 
purposes, e.g. passing to stat() to find the last modification time, passing to 
select() to see if data is available.

[issue25089] Can't run Python Launcher on Windows

[Mark Lawrence]

New submission from Mark Lawrence:

I first asked a few days ago, see this thread 
http://www.gossamer-threads.com/lists/python/python/1216917.  You can work 
around it by running "repair" but it takes an age to run for what, to me 
anyway, is a minor irritant.

[issue25089] Can't run Python Launcher on Windows

[Steve Dower]

Steve Dower added the comment:

Yeah, it's basically impossible to manage PATH automatically. You've probably 
installed 3.5 just for yourself while 3.4 is installed for all users. In this 
case, 3.5 will always lose because Windows puts user paths after system paths.

You could modify 3.4 to remove it from PATH or use py.exe, which resolves 
versions correctly. Or you can modify your PATH manually.

[issue24965] Implement PEP 498: Literal String Formatting

[Martin Panter]

Martin Panter added the comment:

Regarding the null terminator, I was mainly smoke testing your code. :) Maybe 
it would be too hard to support properly. Although I could imagine someone 
doing things like this:

>>> d = {b"key\x00": "value"}
>>> f"key={d[b'key\x00']}"  # Oops, escape code at wrong level
  File "", line 1
(d[b'key
   ^
SyntaxError: EOL while scanning string literal
>>> rf"key={d[b'key\x00']}"  # Corrected
'key=value'

I also finished quickly reading over the C code, with a couple more review 
comments. But I am not familiar with the files involved to thoroughly review.

[issue25090] IDLE: remove noisy icons from class (module) browser

[Terry J. Reedy]

Terry J. Reedy added the comment:

Adding function arguments to the module browser, misnamed Class Browser, is 
#20827.  That leaves removing the noisy icons from class and def entries (where 
they do not fit anyway), as the concrete appearance change proposal here.  
Better to use the space for arguments.

Adding nested classes is #1612262 (9 years ago).  I just noticed that there is 
a 6 year old patch that needs to be reviewed.

The TextMate box has a checkmark at the current location. Having an editor know 
about an attached module browser and inform it of the cursor's location would 
be a separate issue. It would be relatively easy when code context is active.  
But nested classes and functions cannot be marked until they are displayed.

A module browser, even enhanced to display nested classes and functions, could 
not replace code context since the latter includes nested compound statements 
within functions.  I think code context would be even more useful if it were to 
display the complete context, using as many lines as needed, instead of some 
fixed number.  But I have not written a patch yet or opened an issue.

[issue25089] Can't run Python Launcher on Windows

[Steve Dower]

Steve Dower added the comment:

I don't understand what you did and what the result was from that thread.

* What options did you select when installing 3.5?
* What other Python versions did you have? What options were used to install 
them?
* Where was py.exe before installing 3.5?
* Can you attach all of the logs from your 3.5 install (from your %TEMP%)?

[issue25089] Can't run Python Launcher on Windows

[Terry J. Reedy]

Terry J. Reedy added the comment:

For anyone else reading this, Mark says he already re-tried with 3.5.0.

The only problem I had with the install on my Win7, with 2.7.10, 3.4.3, and 
3.5.0rc3 already present, is that 3.4.3 is still the default python (started by 
'python') in spite of checking everything relevant when installing 3.5.0.

[issue25090] IDLE: alternative to class browser / code context

[Mark Roseman]

New submission from Mark Roseman:

Proposal for an alternative or perhaps replacement of both the code context 
extension, as well as the class browser (rooted at a particular file, not the 
path browser).

I'll direct your attention to the attached browser.png. On the right is IDLE's 
class browser window of ClassBrowser.py. On the left, I've got the same file 
loaded into TextMate. 

In the TextMate status bar, it shows you where you're currently located (here, 
in the __init__ function). When you click on that part of the status bar, it 
brings up a scrollable menu showing the structure of the file. I think it's 
easier to read than IDLE's, despite having more information (description of the 
parameters), thanks to reduction in 'chart junk'.

Downside of this approach is that you can't have a window along the side so you 
can navigate the code while seeing the class display. Though that might best be 
achieved if IDLE added a sidebar, rather than a true separate window.

[issue25090] IDLE: alternative to class browser / code context

[Raymond Hettinger]

Raymond Hettinger added the comment:

I don't see anything that replaces Code Context.   That extension is priceless 
for people editing classes and methods that extend more than one screen.

ISTM, there are too many sweeping change proposals that seem to base on general 
look and feel but disregard how people actually use these tools.

[issue1612262] Class Browser doesn't show internal classes

Class Browser is now a module browser as it includes functions not in classes.

[issue25091] Please revert the Windows Installer to micro type.

[Terry J. Reedy]

New submission from Terry J. Reedy:

The 3.4.3 installer used normal size type (10 point, I believe) in the dialog 
boxes.  I can more or less read this with by non 20/20 eyes.  The new 3.5.0 
installer uses a smaller type (8? 7? point), which for even more people will 
mean using a magnifier. Please revert this anti-accessibility change.  Instead, 
increase to 12 point if possible.

I noticed that the Python logo picture is also shrunken by about 20%.  I 
checked side-by-side with the 3.4.3 box, so all system settings were the same 
for both.

[issue25093] New 3.5.0 failure in test_tcl on win7

[Terry J. Reedy]

New submission from Terry J. Reedy:

command,
operable program or batch file.

I am pretty sure test ran fine in .0rc about a month ago, as it does in 3.4.3.

[issue25089] Can't run Python Launcher on Windows

[Mark Lawrence]

Mark Lawrence added the comment:

I install for all users, don't put Python on the PATH, other than that I think 
everything is selected.

I've 2.6, 2.7. 3.3 and 3.4.  I had 3.5.0rc4 and upgraded the existing 
installation to 3.5.0 full release.

I've no idea where py.exe was, but it is now in C:\Windows.  This is what I 
expect having just read PEP397.

Do you really want all logs from the 3.5.0 install and the repair, that's 21 
files?  It's an odd number as there is no log file for the launcher in the 
install but there is in the repair.  The same is true for the rc4 logs.

[issue12420] distutils tests fail if PATH is not defined

[Zachary Ware]

Zachary Ware added the comment:

Agreed with Mark; I don't see anywhere that lack of PATH would affect the 
failures you're seeing, Terry.  Do you have VS2015 installed?  If not, the 
failure of distutils to skip the tests that need it should be raised as a 
separate issue.

[issue25093] New 3.5.0 failure in test_tcl on win7

[Zachary Ware]

Zachary Ware added the comment:

Yes, installation in 'Program Files' produces the failure.  Looks like it's 
probably just bad quoting in the test, but I haven't looked at the code yet.  
This probably affects 2.7 and up, I don't think there have been any changes to 
that test in recent branches.
