[issue25352] Add 'make this my default python' to windows installs for Python3.5 and later

[Laura Creighton]

New submission from Laura Creighton:

webmaster is hearing from children who have downloaded 3.5 but who
are still getting 2.7 when they click on desktop Python icons, and
type python at a console prompt.

a checkbox on the installer saying 'make this my default python' that
would then go off any do all that is necessary in this regard would
make their lives easier.

[issue25349] Use _PyBytesWriter for bytes%args

[STINNER Victor]

STINNER Victor added the comment:

bench_bytes_format.py: micro-benchmark testing a few formats. Some tests are 
focused on the implementation of _PyBytesWriter to ensure that the optimization 
is efficient.

Except of a single test (which is not really revelant, it takes less than 500 
nanoseconds), all tests are faster.

The b"xx %s" % b"y" test confirms that the optimization disabling 
overallocation for the last write is effective.

[issue25356] Idle (Python 3.4 on Ubuntu) does not allow typing accents

[Gian Carlo Martinelli]

Gian Carlo Martinelli added the comment:

Terry, first of all thanks for trying to solve this.

I usually start IDLE using Ubuntu's dash.

The problem is with more than just the three characters. Others that I have 
tested and that don't work include "ç", "`", umlauts... There work in others 
places in my system such as the console for example.

When I try ALT+M or CTRL+O, inside IDLE, these characters work.

This is a copy of my output. Seems OK
!  "  #  $  %  &  '  (  )  *  +  ,  -  .  /  
0  1  2  3  4  5  6  7  8  9  :  ;  <  =  >  ?  
@  A  B  C  D  E  F  G  H  I  J  K  L  M  N  O  
P  Q  R  S  T  U  V  W  X  Y  Z  [  \  ]  ^  _

[issue24402] input() uses sys.__stdout__ instead of sys.stdout for prompt

[Martin Panter]

Martin Panter added the comment:

Okay I plan to commit a modified version where I moved the input() test methods 
that use pseudo terminals to a new PtyTests class. The test_input() method 
stays in the original class, because it shares a helper method with other tests.

I am resisting dropping that decode() step, because it makes any error message 
from the forked child hard to read:

AssertionError: 256 != 0 : b'quux\r\nTraceback (most recent call last):\r\n  
File "/media/disk/home/proj/python/cpython/Lib/test/test_builtin.py", line

[issue25356] Idle (Python 3.4 on Ubuntu) does not allow typing accents

[Terry J. Reedy]

Terry J. Reedy added the comment:

I am not surprised that non-ascii chars fail also. But, all? or just a few (all 
symbol? or only diacriticals)?

My first thought was that you have a european keyboard that is does not match 
your Ubuntu configuration.  Or that you had an older tcl/tk that did not work 
with such.

^O opens a dialog that IDLE is not involved with.  Alt-M open a different tk 
widget that IDLE in not involved with.

Do shell and editor have exactly the same problems?

Let's try two other things.  Alt-F3 opens Find in Files (grep).  Can you enter 
any of `'^~ on the first line?

Put anything on the first line and add a *fake* directory on the second (so you 
have something like zyx/*.py).  Search.  Try typing in the Output Window.  It 
is slightly different from shell and editor (no colors, for instance).

Ankit: I am trying to narrow possibilities using my knowledge of IDLE 
internals.  I wish I knew what *I* need to learn for this.

[issue25351] pyvenv activate script failure with specific bash option

[s-wakaba]

New submission from s-wakaba:

When writing bash shellscripts, I always set options "set -ueC" for strict 
error checking. However, loading pyvenv's activate and deactivate scripts from 
bash with "-u" option, they are failure because they may refer undefined shell 
variables.

I hope activate script and deactivate function are enclosed like following block

_OLD_BASH_OPTIONS="$-"
set +u

### script body ##

set -$_OLD_BASH_OPTIONS
unset _OLD_BASH_OPTIONS


Another option, all shell-variables in the script change like

$SPAM -> ${SPAM:-}

[issue25350] Stronger type enforcement (feature request)

[John Michael Lafayette]

New submission from John Michael Lafayette:

With a lot of languages, I can tell
that the type I am getting is an instance of the declared type I'm assigning it 
to.

Example:
Cat c = Factory.make("cat"
Animal d = Factory.make("dog")

Python:
val c = Factory.make("cat")

Problem with this is that it is not necessarily obvious to the reader what the 
type of c is. I suggest that you provide an option to strengthen python's type 
checking by allowing users to replace val with the expected type of the object 
and then allow the interpreter to check that the real type being assigned is an 
instance of the expected type. An option like -strong for strong typing.

[issue25344] Enhancement to Logging - Logging Stack

[Vinay Sajip]

Vinay Sajip added the comment:

This is already supported. There is a logging.handlers.MemoryHandler which 
allows you to buffer logging events and then pass the buffered events to 
another handler when some condition is met, such as e.g. buffer full or some 
severity threshold is exceeded. Flushing the buffer to the other handler can be 
customised by subclassing and overriding shouldFlush() and perhaps flush() 
methods.

https://docs.python.org/2/library/logging.handlers.html#memoryhandler

I can perhaps add a cookbook recipe to illustrate, so I'll leave this issue 
open for now, as a reminder.

[issue24870] Optimize ascii and latin1 decoder with surrogateescape and surrogatepass error handlers

[STINNER Victor]

STINNER Victor added the comment:

INADA Naoki: "I want to Python 3.4 and Python 3.5 solve this issue since it's 
critical problem for some people."

On microbenchmarks, the optimization that I just implemented in Python 3.6 are 
impressive. The problem is that the implementation is quite complex. If I 
understood correctly, you are asking to optimize decoders and encoders for 
ASCII and UTF-8 (modify 4 functions) for the surrogateescape error handler. Is 
that right? Would UTF-8 be enough or not?

I don't like backporting optimizations which are not well tested right now. To 
optimize encoders, I wrote a full new _PyBytesWriter API. We cannot backport 
this new API, even if it's private. So the backport may be more complex than 
the code in the default branch.

[issue25343] Document atomic operations on builtin types

[Terry J. Reedy]

Terry J. Reedy added the comment:

Yes, I was asking where to put the disclaimer.  The thread docs would be 
approriate if there is nothing already.

Guido has been very reluctant to put any performance guarantees in the language 
reference.  I believe he said that O(f(n)) info even for CPython should be in 
the wiki -- and taken as a guideline, not a iron guarantee.

Further discussion might be better directed to python-ideas, after a search of 
the pydev and python-ideas archives (most easily done with the gmane mirrors, I 
believe).

[issue25352] Add 'make this my default python' to windows installs for Python3.5 and later

[Terry J. Reedy]

Terry J. Reedy added the comment:

There used to be such a checkbox, but apparently it had problems.  But there is 
still something with that effect, at least in part.  When I installed 3.5.0, 
'python' was switched from 3.4 to 3.5.  That did not happen with the 
preliminary releases, because I did somethng different.  Sorry, I don't 
remember what.

I don't like using the start menu over and over either.  So I pin frequently 
used programs to the taskbar -- always visible.  The 2.7 IDLE icon just says 
Python GUI.  In 3.4, it is Python 3.4 GUI.  Ditto for 3.5 and the future.

Steve: when Firefox and some other programs upgrade, the pinned icon remains.  
When Python upgrades, the pinned IDLE icon disappears.  When, as is normal, the 
upgrade is in the same directory, is there any way to leave the icon, since it 
still points to the right directory and filename?  Or is this icon binary 
specific?

[issue25303] Add option to py_compile to compile for syntax checking without writing bytecode

[Pavel Roskin]

Pavel Roskin added the comment:

That's what I have now:

check:
$(PYTHON) -m py_compile $(SOURCES)
rm -f $(addsuffix c, $(SOURCES))

make check
python -m py_compile redacted-build redacted-git-diff redacted-git-gc 
redacted-git-status redacted-init redacted-server
redactedbuilder.py
rm -f redacted-buildc redacted-git-diffc redacted-git-gcc redacted-git-statusc 
redacted-initc redacted-serverc redactedb
uilder.pyc

That's what David is suggesting:

check:
for file in $(SOURCES); do \
python -c "compile(open('$$file').read(), '', 'exec')" || exit 1; \
done

make check
for file in redacted-build redacted-git-diff redacted-git-gc 
redacted-git-status redacted-init redacted-server redactedb
uilder.py; do \
python -c "compile(open('$file').read(), '', 'exec')" || exit 1; \
done

That's what I could have if I live long enough to see Python 3.6 on my 
development machine.

check:
$(PYTHON) -m py_compile --no-output $(SOURCES)

make check
python -m py_compile --no-output redacted-build redacted-git-diff 
redacted-git-gc redacted-git-status redacted-init redacted-server
redactedbuilder.py

If that does not seem like an important improvement, then I can live with what 
I have.

[issue24870] Optimize ascii and latin1 decoder with surrogateescape and surrogatepass error handlers

[STINNER Victor]

STINNER Victor added the comment:

Short summary.

Ok, I optimized ASCII, Latin1 and UTF-8 codecs (encoders and decoders) for the 
most common error handlers.

* ASCII and Latin1 encoders: surrogateescape, replace, ignore, 
backslashreplace, xmlcharrefreplace
* ASCII decoder: surrogateescape, replace, ignore
* (Latin1 decoder cannot fail)
* UTF-8 encoder: surrogateescape, surrogatepass, replace, ignore, 
backslashreplace, xmlcharrefreplace
* UTF-8 decoder: surrogateescape, replace, ignore

The code to handle other error handlers in encoders has also be optimized.

Surrogateescape has now an efficent implementation for ASCII, Latin1 and UTF-8 
encoders and decoders.

1) Do the keys work in the Ubuntu console?
Yes.

2) Do the keys work in interactive python (not IDLE), started with 'python' at 
the console prompt.
Yes.

3) In IDLE, go to Help->About IDLE.  What is the Tk version.
  Best if 8.6.x, if before 8.5.18, upgrade.
8.6.1

4) Try typing in the text box, including the problem chars.  What happens?
Ran the program, all characters work perfectly.

[issue25303] Add option to py_compile to compile for syntax checking without writing bytecode

[Terry J. Reedy]

Terry J. Reedy added the comment:

On the side issue: While the example given, which uses the py_compile.compile 
defaults via the command line interface, is useless, I disagree that writing a 
.pyc file for a file without .py is a bug.

Python will run python code with any filename as main module (and not write 
.pyc).  It will only import the *same code* (and normally write .pyc) if the 
filename ends with .py (or .pyw on windows).  However, 'import script' will 
import script.pyc (on the search path) without a script.py file existing.  
Using py_compile.compile('script', 'script.pyc') makes that possible.  (I just 
tried it.)

Ankit: the issue is where do they fail, why, and how to fix.  Are you running

G.C. How do you start IDLE? Is the problem with exactly those three chars? Do 
they fail in the Shell? an editor? search box? other entry box such as you get 
with Alt-M? Open file dialog (control-O)?

Does this have expected output?

print(chr(m + n), ' ', end='')

[issue24402] input() uses sys.__stdout__ instead of sys.stdout for prompt

[Martin Panter]

Martin Panter added the comment:

I wrote this on Arch Linux, so I doubt your Ubuntu failure is valid. The error 
you see is what I would expect if the bug were not actually fixed. I suspect 
you need to recompile /Python/bltinmodule.c, which contains the bug fix.

However, the test also hangs OS X buildbots. I can only guess at why it is 
hanging, either at the waitpid() line or the os.read() line. I am looking at 
refactoring my test to use the existing check_input_tty() infrastructure. It 
seems over the top by adding a separate pipe back to the parent process, but 
presumably will workaround whatever is causing the hang.

[issue25360] pyw should search for pythonw to implement #!/usr/bin/env python

[eryksun]

New submission from eryksun:

The Windows launcher searches PATH to implement the shebang "#!/usr/bin/env". 
Given "#!/usr/bin/env python", it always searches for L"python" (see issue 
17903), even in pyw.exe. maybe_handle_shebang in PC/launcher.c should instead 
use a macro that's conditionally defined as L"pythonw" when building pyw.exe 
and L"python" when building py.exe. This parallels the existing 
PYTHON_EXECUTABLE macro.

[issue25357] Add an optional newline parameter to binascii.b2a_base64() to not add a newline

[Martin Panter]

Martin Panter added the comment:

The “newline” name seems as good as any. The patch looks good in general. I 
left a few comments.

I agree with not bothering for the UU encoder. That encoding has an embedded 
line length byte at the start of each line, so it makes less sense to omit 
newlines. Base-64 is used in places such as URLs where multiline output is not 
relevant, but I don’t know of a similar case for the UU encoding.

If I was doing it, I wouldn’t bother with a test case for keyword-only-ness, 
but suit yourself.

[issue25194] Opt-in motivations & affiliations page for core contributors

[Nick Coghlan]

Nick Coghlan added the comment:

The attached "Final draft" patch is the version I plan to commit tomorrow. 
Major differences from the previous draft:

* accepted MAL's suggestion of using alphabetical order
* as RDM suggested, explained the rationale for the cases where we encourage 
people to participate
* after fighting with ReST trying to get it to let me have an indented 
paragraph following a bulleted list, I eventually hit on the idea of using the 
"topic" directive to separate entries from each other without introducing an 
ever expanding list of TOC entries on the main page
* there are now more extensive guidelines inline in the doc as a ReST comment
* three cases of "acceptable links to include" are covered: personal sites, 
commercial contact details, and crowdfunding
* questions and suggestions (including for new categories of acceptable links) 
are explicitly directed to the python-committers list

Given the useful feedback from MAL & RDM, I'll hold off on pinging 
python-committers again until this initial version of the page is live.

Does anyone else want to provide an entry for me to include in the initial 
commit? It would be good to have a couple more initial entries to help folks 
generalise from the available examples.

[issue25356] Idle (Python 3.4 on Ubuntu) does not allow typing accents

[Terry J. Reedy]

Terry J. Reedy added the comment:

IDLE uses tkinter which wraps the tcl/tk GUI framework.  Tk handles key 
presses.  So this is almost certainly not an IDLE bug, or even a tkinter bug. 
Unless you can demonstrate otherwise, I will closing this as a CPython issue.

Since this is the first report I know of reporting a problem with ascii chars, 
there is almost certainly something peculiar about your system.  You should 
probably ask for help on python-list (or use the gmane.comp.python.general 
mirror as news.gmane.org).  Here are some preliminary questions.

Do the keys work in the Ubuntu console?
Do the keys work in interactive python (not IDLE), started with 'python' at the 
console prompt.
In IDLE, go to Help->About IDLE.  What is the Tk version.
  Best if 8.6.x, if before 8.5.18, upgrade.

Run the following program (IDLE editor is fine).

from tkinter import *
root = Tk()
text = Text(root)
text.pack()
text.focus_set()  # required to work
root.mainloop()

Try typing in the text box, including the problem chars.  What happens?

[issue25357] Add an optional newline parameter to binascii.b2a_base64() to not add a newline

[STINNER Victor]

New submission from STINNER Victor:

The base64.b64encode() function calls binascii.b2a_base64() and then strips the 
newline. It would be more efficient to directly not add a newline.

Attached patch adds an optional newline parameter to binascii.b2a_base64(). It 
also modifies base64.b64encode() to call binascii.b2a_base64() with 
newline=False.

I think Ned meant "it is *not* likely to be in the python interpreter or 
standard library", and that you should seek help from the third party people 
trying to track down the problem.  *If* it turns out to be python or the 
stdlib, which means you've managed to find a reproducer that does *not* involve 
the third party packages, *then* come back and reopen the issue.

Like Ned said, good luck, but we really can't provide you any more help here 
until the third party packages are eliminated from the equation.

[issue25303] py_compile disregards PYTHONDONTWRITEBYTECODE and -B

[Éric Araujo]

Éric Araujo added the comment:

I had the same reasoning as RDM when I worked on byte-compilation in 
distutils2: https://hg.python.org/distutils2/rev/7c0a88497b5c

Using py_compile or compileall means that you want to create pyc or pyo files.
Defining PYTHONDONTWRITEBYTECODE or -B means that you don’t want the Python 
interpreter to byte-compile module as a side-effect of importing them.
These two things seem orthogonal to me.

[issue25357] Add an optional newline parameter to binascii.b2a_base64() to not add a newline

[Serhiy Storchaka]

+1. Not sure about the parameter name, but if no one suggests better, it LGTM. 
Added comments on Rietveld.

What about adding the same parameter to binascii.b2a_uu()?

[issue25318] Add _PyBytesWriter API to optimize Unicode encoders

[STINNER Victor]

STINNER Victor added the comment:

Buildbots still like this new API :-) (no test failure recently)

I reworked the API a little bit to make its usage simpler in Unicode encoders. 
I started to open new issues to using this new API in more functions producing 
byte strings.

I consider that this issue can now be closed. I'm happy, the API looks good to 
me and the modified code is faster.

[issue25353] Use _PyBytesWriter for unicode escape and raw unicode escape encoders

[STINNER Victor]

New submission from STINNER Victor:

Attached patch modifies unicode escape and raw unicode escape encoders to use 
the new _PyBytesWriter API.

The patch is optimized to encode Latin1 characters: encoding Latin1 characters 
when no character is escaped should not have to call _PyByte_Resize() at all.

When characters are escaped or a BMP or non-BMP string is encoded, 
overallocation is used to reduce the number of _PyByte_Resize(). It uses 
_PyBytesWriter overallocation strategy instead of always overallocate for the 
worst case.

_PyBytesWriter also embeds a small buffer allocated on the stack which also 
avoids calls to _PyBytes_Resize() when the output fits into 512 bytes.

They can find the 3.5 shortcut in their Start Menu (either by browsing or

Depending on operating system version, moving it could be:

* drag from the Start Menu to the desktop and drop it
* right-click and choose "Send To -> Desktop (create shortcut)", OR
* right-click, choose "Open File Location" and then right-click again in the 
new window and choose "Send To -> Desktop (create shortcut)"

This function is used in Lib/encodings/uu_codec.py and Lib/uu.py, but the 
newline is not stripped. So I don't think that it's worth to add an optional 
parameter.

The py launcher will prefer 2.7 because that's what was decided when it was 
added. We're probably getting to a stage where we can revert that.

Unfortunately, there's no way we can reliably fix system configuration without 
corrupting the users machine. Using the py launcher with -3 is currently the 
best way to do it.

I don't know where the desktop shortcuts are coming from - they're not ours, so 
we can't fix them.

[issue25311] Add f-string support to tokenize.py

[Eric V. Smith]

Eric V. Smith added the comment:

I think the best way to approach this is to generate (in code) all of the 
places where string prefixes appear. There's StringPrefix, endpats, 
triple_quotes, and single_quoted.

With the currently valid combinations of f, b, r, and u, I count 24 
combinations:
['B', 'BR', 'Br', 'F', 'FR', 'Fr', 'R', 'RB', 'RF', 'Rb', 'Rf', 'U', 'b', 'bR', 
'br', 'f', 'fR', 'fr', 'r', 'rB', 'rF', 'rb', 'rf', 'u']

If I add "fb" strings (plus raw), I count 72 combinations:
['B', 'BFR', 'BFr', 'BR', 'BRF', 'BRf', 'BfR', 'Bfr', 'Br', 'BrF', 'Brf', 'F', 
'FBR', 'FBr', 'FR', 'FRB', 'FRb', 'FbR', 'Fbr', 'Fr', 'FrB', 'Frb', 'R', 'RB', 
'RBF', 'RBf', 'RF', 'RFB', 'RFb', 'Rb', 'RbF', 'Rbf', 'Rf', 'RfB', 'Rfb', 'U', 
'b', 'bFR', 'bFr', 'bR', 'bRF', 'bRf', 'bfR', 'bfr', 'br', 'brF', 'brf', 'f', 
'fBR', 'fBr', 'fR', 'fRB', 'fRb', 'fbR', 'fbr', 'fr', 'frB', 'frb', 'r', 'rB', 
'rBF', 'rBf', 'rF', 'rFB', 'rFb', 'rb', 'rbF', 'rbf', 'rf', 'rfB', 'rfb', 'u']

Coding these combinations by hand seems insane.

The test for datetime module keeps failing.

In datetimetester.py , in function test_issue23600 , line 196:
the variable DSTDIFF has been assigned timedelta of 1 hour, I guess it should 
be , 

DSTDIFF = timedelta(hours=0)

It passes the test then. 

The comment in the function code says -  
"""Simple time zone which pretends to always be in summer time, since that's 
what shows the failure.""" Was the test written to fail on purpose ?

[issue25303] py_compile disregards PYTHONDONTWRITEBYTECODE and -B

[Terry J. Reedy]

Terry J. Reedy added the comment:

I agree that the proposal as written should be rejected.  I am inclined to 
think this issue should be closed.

I do not understand the claim about 'python -m py_compile'.  For me, this does 
nothing, as I would expect from reading the code.  If args = sys.arg[1:] is 
empty, the else clause for loop immediately quits.

Syntax checking is easily done with compile; that is how IDLE does it.  
  python -c "compile(open().read(), '', 'exec').
should do what Pavel tried to do, except for getting a SyntaxError instead of 
py_compile.PyCompileError.

[issue19500] Error when connecting to FTPS servers not supporting SSL session resuming

[Alex Warhawk]

Alex Warhawk added the comment:

Even after enabling client cache one still has to call SSL_set_session. See 
documentation of SSL_CTX_set_session_cache_mode point SSL_SESS_CACHE_CLIENT.

I started thinking about not exposing a SSL_SESSION object to the user but 
rather extending wrap_socket to take an already established socket as argument 
and use that socket's session object. This way I can ensure that both sockets 
share the same SSL context

I am not really convinced by this idea myself, what do you think about this? 
Any better ideas?
