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

[Terry J. Reedy]

Terry J. Reedy added the comment:

Patch amounts to putting 3 lines of apply inline and moving the first up to 
where is it needed.  Serhiy, thanks for discovering the simple fix.  It worked 
for me so I pushed it.  I backported because the cascade of error messages is 
nasty when visible and because the forward merge was easy enough now that I 
know about the case clash problem.

[issue27099] IDLE: turn builting extensions into regular modules

[Ned Deily]

Ned Deily added the comment:

Terry, I don't know that much about the history of the config files.  I do know 
that during framework installs of Python on OS X, the "install_IDLE" recipe in 
Mac/Makefile.in (which ./configure uses to produce a configured Mac/Makefile) 
has some editing steps, using sed, to alter the IDLE .def files as they are 
being installed.  I'm attaching the two edited .def files as installed by the 
OS X installer.  And then there's the runtime munging of "Alt-" to "Option-" in 
GetCurrentKeySet() of idlelib/config.py.

[issue27305] Crash with "pip list --outdated" on Windows 10 with Python 2.7.12rc1

[Eryk Sun]

Eryk Sun added the comment:

I get an access violation due to calling the ASN1_ITEM pointer as a function:

>  810:  ASN1_ITEM_ptr(method->it)));
_ssl!_get_peer_alt_names+0x12a:
7ffe`17b1225a ffd0callrax

   +0x018 funcs: (null)
   +0x020 size : 0n0
   +0x028 sname: 0x7ffe`17cb5bf8  "GENERAL_NAMES"

I know very little about OpenSSL or the _ssl module, but I think the default on 
Windows is to define OPENSSL_EXPORT_VAR_AS_FUNCTION, in which case:

/*
 * Platforms that can't easily handle shared global variables
 * are declared as functions returning ASN1_ITEM pointers.
 */

/* Macro to obtain ASN1_ITEM pointer from exported type */
#  define ASN1_ITEM_ptr(iptr) (iptr())


The 2.7.10 build uses a function pointer:

>  810:  ASN1_ITEM_ptr(method->it)));
_ssl!_get_peer_alt_names+0xe8:
`02681c78 ffd0callrax
  {_ssl!GENERAL_NAMES_it

   +0x020 size : 0n0
   +0x028 sname: 0x`0284aa30  "GENERAL_NAMES"

Except _ssl links to OpenSSL statically, so strictly speaking this shouldn't be 
necessary. The 3.5 build uses a global variable here instead of a function 
pointer:

>  847: if(!(method = X509V3_EXT_get(ext))) {
_ssl_d!_get_peer_alt_names+0xe9:

Terry J. Reedy added the comment:

Ned, from your response on 20580, there appears to be no conversion rule.  
Perhap you could go throuch config-main.def and make a list of what you want 
for Mac and Unix respectively, if different from the current binding.  Serhiy, 
should anything be different for Linux?, or for your Modern Linux?

[issue25782] CPython hangs on error __context__ set to the error itself

Yury Selivanov added the comment:

> issue27122_broken_cm.py also shows why I think "make it work" is the right 
> answer here [..]

But fixing this issue by reordering the exception chain will only mask bugs 
that just better to be fixed.  And sometimes, this will cause weird exceptions 
chains, that will make *some* people spend a lot of time debugging/googling to 
understand what's going on.

It seems to work fine on my build machine (Win Server 2012) but not my laptop

causing the crash, but until I get a chance to debug properly I can't be sure. 
Hopefully I'll get a chance to look tomorrow.

[issue27312] test_setupapp (idlelib.idle_test.test_macosx.SetupTest) fails on OS X

[Terry J. Reedy]

Terry J. Reedy added the comment:

test_setupapp calls setupApp with body 
if isAquaTk():
hideTkConsole(root)
overrideRootMenu(root, flist)
addOpenEventSupport(root, flist)
fixb2context(root)
isAquaTk should be True exactly twice, and it failed both times.  The overall 
code is definitely not re-entrant  On Carbon, 'application' in inserted before 
'file' and becomes menudef[0].  The puzzle to me is the failure on what should 
be the first call.

Until that is figured out, you could try decorating test_setupapp with
@mock.patch(idlelib.macosx.setupApp)
to see what, if anything, fails next.

I have access to a small Macbook Air with 11" diag. screen -- probably too 
small for my eyes for routine use but I should be able to run test_idle 
(especially post push) and do occasional exploratory editing, as needed here.  
I will try to learn enough about how to use it to follow the devguide 
instructions on setting up a repository.

[issue27314] Cannot install 3.5.2 with 3.6.0a1 installed

[Steve Dower]

Steve Dower added the comment:

Okay, it's not an issue with the newer versions, and I don't see any reason to 
worry about 3.6.0a1.

One issue that remains is that installing the launcher with 3.6.0 creates a 
separate add-remove programs entry and doesn't remove the 3.5.2rc1 entry, but 
the reference counting on files seems to be fine, so it's not a big deal and 
something I'll fix before 3.6 releases.

[issue27314] Cannot install 3.5.2 with 3.6.0a1 installed

[Steve Dower]

New submission from Steve Dower:

(Originally posted as a comment to issue26631 but confirmed separately.)

For 3.5.2 and 3.6.0a2, I updated the installer for the launcher so that it is 
always shared between Python versions (i.e. if you install 3.6 followed by 3.5, 
it won't touch the launcher because there's a "newer" one there).

However, because this didn't make it into 3.6.0a1, there is actually a version 
conflict that breaks installation.

I've marked this a deferred blocker for now and brought in the two RMs. I 
believe (and will test with the RCs) that this won't recur with the latest 
versions. It can also be easily worked around by choosing not to install the 
launcher.

We haven't seen this before because there have been no supported "downgrade" 
scenarios (i.e. installing 3.5.0 over 3.5.1 aborts at the start, well before 
this error would be seen).

[issue27263] Tkinter sets the HOME environment variable, breaking scripts

[Terry J. Reedy]

Terry J. Reedy added the comment:

How about wrapping the appropriate tkinter code with (untested yet)

import os
HOME = os.environ['HOME']
try:

finally"
os.environ['HOME'] = HOME  # will this unset?

or use a restore_env('HOME', ...) context manager?

Revising os.expanduser or apps to ignore HOME while tk is running is a related 
but different issue.

[issue27312] test_setupapp (idlelib.idle_test.test_macosx.SetupTest) fails on OS X

[Ned Deily]

Ned Deily added the comment:

Without looking closely at it, I would speculate that the failures are due to 
trying to test code in overrideRootMenu() that was previously only called once 
during execution and may not be re-enterant:

# Remove the last 3 items of the file menu: a separator, close window and
# quit. Close window will be reinserted just above the save item, where
# it should be according to the HIG. Quit is in the application menu.
del mainmenu.menudefs[0][1][-3:]
mainmenu.menudefs[0][1].insert(6, closeItem)

[issue27311] Incorrect documentation for zipfile.writestr()

[John Hagen]

New submission from John Hagen:

The function signature and description for zipfile.writestr is incorrect:

https://docs.python.org/3.5/library/zipfile.html#zipfile.ZipFile.writestr

See:
https://github.com/python/cpython/blob/master/Lib/zipfile.py#L1610

The documentation calls the parameter 'bytes', but the real parameter name is 
'data'.

Looks like this was not fixed when the source changed to Python 3:

[issue27310] 3.6.0a2 IDLE.app on OS X fails to launch, use command line idle3.6 instead

[Ned Deily]

New submission from Ned Deily:

For 3.6.0a2, when attempting to launch IDLE.app on OS X (for example, by 
double-clicking the IDLE icon in the "/Applications/Python 3.6" folder), IDLE 
does not launch.  In the system.log there will be a log message similar to:

(org.python.IDLE.917792[45897]): Service exited with abnormal code: 1

The problem is that the glue code (idlemain.py) used to launch IDLE from within 
the IDLE app bundle is trying to import macosxSupport which has been renamed as 
of 3.6.0a2.  However, there is no longer any reason for the app bundle to 
import this module: this is vestigial code that I should have removed some 
releases ago when I refactored macosxSupport.  It hasn't hurt up until now.

As a workaround for 3.6.0a2, you can launch IDLE from a terminal command line:

/usr/local/bin/idle3.6

or you *could* carefully msnuslly edit the file /Applications/Python 
3.6/IDLE.app/Contents/Resources/idlemain.py to remove the two lines near the 
end:

from idlelib import macosxSupport
macosxSupport._appbundle = True

Fix for 3.6.0a3 to follow.

[issue25782] CPython hangs on error __context__ set to the error itself

[Nick Coghlan]

Nick Coghlan added the comment:

Thanks Serhiy. I've attached a new file (issue27122_broken_cm.py) with a 
context manager that is deliberately buggy in the same way as 
contextlib._GeneratorContextManager is currently, so the new test can be made 
independent of #27122 being fixed (Greg Smith has a pending patch to make that 
CM well behaved again, which would currently lead to your new test passing for 
the wrong reasons)

issue27122_broken_cm.py also shows why I think "make it work" is the right 
answer here - the odd context chaining is tolerated in the case where the 
interpreter is implicitly setting the exception context, so I believe it should 
also be tolerated when ExitStack sets the context explicitly. If we "do the 
right thing" (where "right" = "the same as what the interpreter does") in the 
setter, then not only ExitStack, but anyone else setting __context__ should 
automatically benefit from the adjustment.

[issue20580] IDLE should support platform-specific default config defaults

[Ned Deily]

Ned Deily added the comment:

"I have the impression from what you wrote above that every 'Control' should be 
'Command'."

I'm not sure where I gave that impression but, no, the default IDLE keyset on 
OS X has command accelerators with Command- modifiers and some with Control- 
modifiers, as is typical of OS X applications.

[issue27173] Modern Unix key bindings for IDLE

[Ned Deily]

Ned Deily added the comment:

"Please confirm that Classic OSX is the right choice over Classic Mac"

It is.  At least, when we install IDLE on OS X, Clsssic OS X is the default 
set.  I don't know why Classic Mac exists; I'm guessing it is left over from 
Mac OS 9 days (pre OS X).

[issue27099] IDLE: turn builting extensions into regular modules

[Terry J. Reedy]

Terry J. Reedy added the comment:

Ned, I reread #20580.  It reminds me that both Control and Alt are problems.  
In built-in config-extensions.def, the builtin fixed bindings and one of the 
configurable bindings are:

autocomplete:

calltips:   
parenmatch:   

runscript:  (configurable)

I presume that these all work fine on Macs.  Every other configurable binding 
uses 'Control' or 'Alt'.  When I copy configurable bindings into the file, I 
have to put them in each section.  Should I change each to 'Command' or 
'Option' for the 'Mac' and 'Osx' sections?  Also see comment on #20580.

I am adding #27173 as a dependency, for now, because it might be easier to 
include the new key set before starting to add new bindings.

Ned, looking at config-keys.def, the Mac and Osx sections have a mixture of

every 'Control' should be 'Command'.  Why are the sections as they are?

The first line of the last message should have said 'in addition to' instead of 
'rather than', In the following expanded table, Key is the number of 
pseudoevents with configurable and fixed key bindings.  Gen is the number of 
General pseudoevents. (Current, from config-main.def.)

File  MenuKey  Gen

autoexpandEdit - Expand Word  1,-   -

My initial experiment with adding a fake event and binding in the user 
config-keys.cfg does not affect existing versions.  It appears to be completely 
ignored and does not appear on the list of configurable keys in the dialog.

This answer 
(http://stackoverflow.com/questions/33792008/python-tkinter-ttk-themed-message-box/33801260#33801260)
 to the Stack Overflow question states that Tkinter's messageboxes use 
non-themed controls due to the fact that python.exe and pythonw.exe lack 
manifest which notifies Windows that application supports Visual Styles.
Is there any specific reason it's not used?

[issue27263] Tkinter sets the HOME environment variable, breaking scripts

[Jarrod Petz]

Jarrod Petz added the comment:

eryksun, now I understand this is a bit more challenging because tkinter is the 
underlying library doing this and it is shared by other apps.

Though I still don't feel that just because its been like this since 1995 means 
it should stay this way. This is something which breaks other code following 
the python os.path.expanduser way(and probably other thing looking at the 
evitonmeny HOME). Not all people will try getting to the bottom of why, 
esspecially if they are a new user. It should just work.

Would iy be possible for tkinter to allow the user/app to decide the behavior?

Ie. Have a setting(s)/switch which allows the default behavior of setting and 
using HOME to be overiden.

By doing that existing apps remain unchanged and apps like IDLE could change 
this behavior to whatever they want when they are ready.

I think os.path.expanduser() behavior is by far more logical. Preference 
USERPROFILE if HOME is missing. USERPROFILE on windows is needed to even login. 
HOMEDRIVE/HOMEPATH is not.

[issue26386] tkinter - Treeview - .selection_add and selection_toggle

[Terry J. Reedy]

Terry J. Reedy added the comment:

LGTM, but after applying to all 3, leave open (or open new issue) to replace 
patch in 3.6  (before beta 1).

Change signature to *items.  That will automatically make a single string 
become a len 1 tuple.  For selection (list the 4 selops and) add a note.  "For 
back compatibility, one may also pass a single tuple (or list?) of items." and 
Version Changed.  For 4 derivatives, 'See selection.' In the code, instead add 
(untested):

if len(items) == 1:  # Remove after deprecation.
item0 = items[0]
if not isinstance(items[0], isinstance(str)):
raise DeprecationWarning(
 
 "The option of passing multiple items as a tuple "
 "rather than as multiple items is deprecated and "
 "will be removed in 2020 or later.")
items = items0  # or more processing if lists were allowed

Revise test accordingly.

As it stands, I can't build 64-bit with my setup and the 32-bit build 
seems fine so it's hard to bisect. I'll try to get a 64-bit build 
working to give better information. (The trace above is from an attached 
debugger).

[issue25782] CPython hangs on error __context__ set to the error itself

[Nick Coghlan]

Nick Coghlan added the comment:

For both of the proposed patches, could we add a test case based on 
contextlib.ExitStack and a variant of Victor's #27122 reproducer script at 
http://bugs.python.org/file42999/hang_bug2.py that uses a deliberately broken 
__exit__ implementation that always re-raises the exception thrown into the 
underlying generator?

As discussed on that issue, I'm wondering if we need some additional defensive 
coding in ExitStack itself, or if resolving this underlying problem will be 
enough to also categorically prevent the hang in ExitStack.

As far as possible resolutions go, I tend to prefer lying about the shape of 
the exception state over changing the type of the raised exception - we already 
know the true exception state is a tree rather than a chain (see #18861 for 
some related discussions), and we should be able to ensure that all active 
exceptions remain somewhere in the chain, even if their order is a bit 
surprising.

Yury Selivanov added the comment:

> Yury's raises a RuntimeError in the loop situation.

Right, and I believe that my solution is more Pythonic.  Reordering feels 
highly unintuitive to me.

[issue27122] Hang with contextlib.ExitStack and subprocess.Popen (regression)

[Nick Coghlan]

Nick Coghlan added the comment:

Greg, I think you should apply your change to eliminate the regression and get 
us back to the state of all stdlib context managers being well-behaved in this 
regard (we unfortunately missed the 3.5.2 release, but that will ensure it's 
fixed for 3.5.3).

Given the challenges I had trying to reproduce the hang with a plain context 
manager rather than a generator, I now the problem is specifically just #25782 
- in the absence of that, ExitStack() should misbehave in the same way actual 
nested with statements would, rather than trying to implicitly "fix" the 
misbehaving context managers.

[issue19570] distutils' Command.ensure_dirname fails on Unicode

[Adam Bartoš]

Adam Bartoš added the comment:

Recently, I was also hit by this when trying to autoset `sys.argv` to a list of 
Unicode string (see 
https://github.com/Drekin/win-unicode-console/issues/20#issuecomment-225638271 
).

It would be nice to have this fixed. It seems to me (I may be wrong) that every 
occurence of `isinstance(…, str)` is a potential bug in Python 2.7. Either it 
should be spelled out as `isinstance(…, bytes)` or there should be 
`isinstance(…, types.StringTypes)` or even `isinstance(…, unicode)`.

[issue27308] Inconsistency in cgi.FieldStorage() causes unicode/byte issue.

[Marcel Hellkamp]

New submission from Marcel Hellkamp:

Discovered here: https://github.com/bottlepy/bottle/issues/856

If a multipart section has a "Content-Length" header, but no "filename" 
attribute in the "Content-Disposition" header, cgi.FieldStorage tries to write 
binary data to a temporary file opened in text-mode.

The problem here is that cgi.FieldStorage tries to decide if something is a 
binary file-upload or a unicode form-field, but it does so based on two 
different headers in two different places. If the headers contradict each other 
(form-fields usually don't have a Content-Length, file-uploads usually have a 
filename), parsing breaks with a TypeError.

Unfortunately, there are some HTTP client libraries out there that trigger this 
bug.



Here is what happens:

A "Content-Length" header causes `cgi.FieldStorage.length` to be is set (which 
is fine).
https://hg.python.org/cpython/file/3.4/Lib/cgi.py#l550

If `length` has a value, `read_binary()` is used instead of `read_lines()` 
(which is questionable).
https://hg.python.org/cpython/file/3.4/Lib/cgi.py#l733

`read_binary()` calls `make_file()` which creates the buffer file in text mode 
if it does not find a `filename` attribute in the "Content-Disposition" Header 
(which is somewhat okay).
https://hg.python.org/cpython/file/3.4/Lib/cgi.py#l515
https://hg.python.org/cpython/file/3.4/Lib/cgi.py#l893

The bug is triggered if the last two steps disagree on the bytes vs. text 
question.

Provisional addition a bit revised from above.  I did not markup idlelib as a

how IDLE can be linked to the IDLE doc.  I linked to the name change issue that 
started the change process. I will add a link to the interface issue if and

[issue24869] shlex lineno inaccurate with certain inputs

[Gareth Rees]

Gareth Rees added the comment:

A third alternative:

3. Add a method whose effect is to consume comments and whitespace, but which 
does not yield a token. You could then call this method, and then look at 
shlex.lineno, which will be the line number of the first character of the next 
token (if there is a next token).

[issue24869] shlex lineno inaccurate with certain inputs

[Gareth Rees]

Gareth Rees added the comment:

Just to restate the problem:

The use case is that when emitting an error message for a token, we want to 
include the number of the line containing the token (or the number of the line 
where the token started, if the token spans multiple lines, as it might if it's 
a string containing newlines).

But there is no way to satisfy this use case given the features of the shlex 
module. In particular, shlex.lineno (which looks as if it ought to help) is 
actually the line number of the first character that has not yet been consumed 
by the lexer, and in general this is not the same as the line number of the 
previous (or the next) token.

I can think of two alternatives that would satisfy the use case:

1. Instead of returning tokens as str objects, return them as instances of a 
subclass of str that has a property that gives the line number of the first 
character of the token. (Maybe it should also have properties for the column 
number of the first character, and the line and column number of the last 
character too? These properties would support better error messages.)

2. Add new methods that return tuples giving the token and its line number (and 
possibly column number etc. as in alternative 1).

My preference would be for alternative (1), but I suppose there is a very tiny 
risk of breaking some code that relied upon get_token returning an instance of 
str exactly rather than an instance of a subclass of str.

[issue27305] Crash with "pip list --outdated" on Windows 10 with Python 2.7.12rc1

[Paul Moore]

Paul Moore added the comment:

Thanks Tim.

To clarify, the only 2 places that pip calls ctypes is to get the user 
application directory (and we've confirmed that doesn't error when called 
direct from Python), and in the vendored colorama package (which we removed and 
still got the crash, so it's not that).

So as far as we can tell, the crash is occurring from pure Python code, which 
as the OP pointed out, should not occur. The issue has also been confirmed as 
not happening with 2.7.11.

If anyone can suggest a way for the OP to get better information out of Python 
as to where the problem is occurring, I'm happy to debug further with him in 
the pip code in order to reproduce the issue.

Python Packaging Authority member pfmoore from pypa/pip says "there's no 
ctypes-based code that could be causing the error" and "Python appears to be 
crashing as a result of pure Python code" and "there's no way that I can see 
how pip could be triggering a crash here. As this doesn't happen with 2.7.11, 
I'm inclined to consider it as a 2.7.12rc1 bug, I'm afraid."

feel that Python.exe should not crash even if there is a problem with a 
third-party package.

[issue26686] email.parser stops parsing headers too soon.

[Martin Panter]

Martin Panter added the comment:

FWIW in the HTTP bug , David said 
“when seeing a line that doesn't look like a header the error recovery is to 
treat that line as the beginning of the body (ie: assume the blank line is 
missing).” I have no experience with email and RFC 5322 header handling, but it 
does make more sense to me to handle this as a defect in the header section, 
_not_ a genuine transition to the body (same as desired for the HTTP case).

Here is a patch that revives MalformedHeaderDefect (see Issue 14925), and 
continues parsing the rest of the header section instead of starting the body. 
But I am not sure how safe this change is. I did have to fix one unrelated set 
of tests (see headertest_msg in the Test8BitBytesHandling class) that did not 
include a blank line and was relying on the old behaviour.
