[issue24790] Idle: improve stack viewer

2015-08-18 Thread Can İbanoğlu


Can İbanoğlu added the comment:

Hello again,

I have spent some time going over the code and how the PyShell brings all of 
this together and have formed some loose opinions on how to solve these issues 
but I wanted to get a much more informed opinion.

I will provide a patch for the first one first, so right now, all my questions 
are related to that one.

Basically, I have come up with three different places I could patch in 
StackViewer.py to remove idlelib.run.runcode from the stack viewer. 

First option is to patch the constructor of StackTreeItem so that if 
idlelib.run.runcode is in the traceback, it never gets pushed to the stack 
list. I don't like this approach very much because I would essentially be 
removing data from the stack. 

Second option is to patch the GetSubList method so that the iterated variable 
info is checked before constructing a new FrameTreeItem. If 
idlelib.run.runcode is matched, we would just continue to the next value in 
the list. I think this would lead to repetitive code though. We would rewrite 
some of the GetText method of FrameTreeItem and then make a string 
comparison to identify the entry to be removed.

Third option is to call the GetText method after each created FrameTreeItem 
and make the string comparison then. This would add a lot of method calls if 
the stack is long. On the other hand, this approach doesn't repeat any code. 

It is highly possible that I have missed something very simple and elegant :) I 
would very much appreciate your input. I can make upload a patch once I get 
your approval. Which approach would be better here?

Something else that I would like to ask is the preparation of the patch file. 
Should switch to the 3.4 branch and then create the patch or can I do it at the 
dev branch? How would I check if the patch applies to 3.4/3.5/3.6 (apart from 
applying them manually and testing if it has the desired outcome)?

I'm sorry for the wall of text, I'm nervous and I don't want to mess something 
up. :)

Thanks a lot for your assistance.

[issue24887] Sqlite3 has no option to provide open flags

2015-08-18 Thread Cal Leeming


New submission from Cal Leeming:

There are several flags which can be provided to Sqlite3 during connection [1]. 
Alternative libraries such as apsw provide the ability to use these flags [2], 
however it would be nice if `sqlite3` supported this out of the box.

Is there any reason why the wrapper for `sqlite3` does not allow flags to be 
passed in? If not, can we add it?

[issue24886] open fails randomly on AIX

2015-08-18 Thread Arnon Yaari

New submission from Arnon Yaari:

We are using Python 2.7.8 on AIX 7.1 TL 3.
On rare occasions, calls to open files with mode w fail with: IOError: File
exists.

File
/root/jenkins/workspace/powertools/eggs/infi.credentials_store-0.1-py2.7.egg/infi/credentials_store/base.py,
line 175, in set_credentials
with open(self.get_file_path(), 'w') as f:
IOError: [Errno 17] File exists: '/root/.infinidat/infinihost'

This happens randomly on multiple systems and different files (including e.g.
/dev/null).
This is very strange because File exists should only be raised if we open the
file with the 'x' flag (os.O_EXCL) and we don't.
After debugging, we discovered that this happens due to a bug in AIX. On AIX,
fopen checks for mode[2] (where 'mode' is the second argument passed to it - in
our case, w) regardless of its length. fopen checks this byte against 'x' to
decide if O_EXCL should be used. In the case of passing w as 'mode', mode[2]
will contain undefined data -- and in rare cases it will contain the byte 'x'.
This was reported to IBM and APARs exist for this issue:
http://www.ibm.com/support/docview.wss?uid=isg1IV64453 (see related APARs for
various AIX versions in this page)

Python can and should work around this because the code in fileobject.c is also
partly to blame:
Python 2.7.x contains the following lines:

/* probably need to replace 'U' by 'rb' */
newmode = PyMem_MALLOC(strlen(mode) + 3);

For the 'mode' parameter, Python allocates 3 additional bytes that are not
always used, and these bytes contain uninitialized data. The byte 'x' that
causes the problem comes from this allocation. Python should set the bytes to
zero to avoid this issue.
I'm attaching a patch. Note that this applies only to the 2.x branch.

7. Sorts global and local names (as with dir()).

8. Don't expand values with their class attributes, at least not for builtins.  
Example

+ dir icon __doc__  = None

Clicking + gives all the attributes of type(None), each with its own +.  It 
does not do this for ints and strings.

[issue8987] Distutils doesn't quote Windows command lines properly

2015-08-18 Thread Chris Hogan


Chris Hogan added the comment:

At Intel, we've run into problems with external modules giving paths to 
_nt_quote_args that contain trailing backslashes, which escapes the final quote 
and breaks the command.  This fix takes care of special characters, trailing 
backslashes, and embedded quotes as in Matt's example.  I've also added unit 
tests for these cases, as well as a high level test that builds an extension 
and defines some macros that contain quotes and special characters. 

setup.py - Includes a library directory with a trailing backslash. I compiled a 
simple library, test_module.lib, and put it in that directory to test the 
linking.  This fails without my fix.  The macro definitions also fail without 
this fix.

testmodule.c - A simple C extension.  It just makes sure everything worked and 
returns the string Success!

As for current workarounds in setup scripts, I know numpy uses their own 
distutils.  They wrote a quote_args() function that they use instead of 
_nt_quote_args(). It checks for spaces, but only if the argument isn't already 
quoted.  It doesn't account for other special characters or trailing 
backslashes.

Your research is very helpful.  The purpose of 1. *is* to remove data ;-) -- 
data that is only present because of Idle.  The purpose of  
StackTreeItem.get_stack is to removed unneeded data while converting a linked 
list to a regular list.  Note that the loop drops 2 of 4 fields. I do not know 
if
if tb and tb.tb_frame is None:
tb = tb.tb_next
actually removes anything, but after this, I believe that the 
idlelib.run.runcode node (or idlelib.PyShell.runcode node, when Idle is started 
with -n) is at the top of the linked list.  So I believe adding
tb = tb.tb_next
after the above will do what we want.  Try it, and if it works, move on.

6 (modeled after 3). Modules only have +Globals.  Remove +Globals under each 
module and instead display globals when expanding. (There will only be a module 
other than __main__ when there is an error in another module being imported.  
We should then improve the lines to read
  + Globals for module __main__ ...
  + Locals for function xyz...

Yury Selivanov added the comment:

LGTM.

FWIW, using 'self.from_exception(..)' is better because this way it's easier to 
override the method.  Another way would be to write 
'type(self).from_exception(..)', but I think using 'self' is good enough.

[issue24294] DeprecationWarnings should be visible by default in the interactive REPL

2015-08-18 Thread Jim Jewett


Jim Jewett added the comment:

I've changed the stage to test needed. 

At a minimum, an interactive test should be written and added to the 
documentation.  Better would be an automated test (perhaps via subprocess).

The documentation should also be updated; at a minimum, there should be a 
versionchanged to say when the default changed. Ideally, also some 
clarification on the intended differences between DeprecationWarning and 
PendingDeprecationWarning, and whether there are any behavioral differences.

[issue24890] Windows launcher docs don't fully explain shebang semantics

2015-08-18 Thread Brendan Barnwell


New submission from Brendan Barnwell:

With the fix of issue #17903 in place, the behavior of the Windows launcher for 
a shebang of #!/usr/bin/env python is now different from the behavior for the 
other virtual commands in that the PATH is searched for this particular 
virtual command but not the others.  But this difference is not explained in 
the docs (see https://docs.python.org/3/using/windows.html#shebang-lines).  The 
docs should be updated to make the difference clear.

In addition, as noted in bug #24625, the launcher parses and executes shebang 
lines normally if the shebang is not one of the virtual commands.  However, 
this is not actually stated on the documentation page; the only examples on the 
page either use the virtual commands or use a bare command like python.  
Given that shebang lines don't normally work at all on Windows, and given that 
the shebang handling is already different on Windows because of the virtual 
commands, the docs shouldn't assume that it's clear what works like a normal 
shebang means.  A note should be added to the docs to make this explicit.  
Something like If the shebang line is not one of these virtual commands, it is 
executed as a normal program and the script filename is passed to it as a 
command-line argument.

[issue24889] Idle: always start with focus


New submission from Terry J. Reedy:

On Windows, starting Idle with an icon or at console brings up shell or editor 
window with focus, ready to receive input. Starting Idle from a built python_d 
in interactive console mode with ' import idlelib.idle' brings up an Idle 
shell with a cursor blinking at the ' ' prompt, but leaves the input focus 
with the console until one clicks on the Shell window.  This is quite annoying 
and I want to fix it.

I have the impression that this may be a Windows-only problem.  True?

PyShell.main calls PyShellFileList.open_shell, which calls PyShell.begin. I 
believe this is the only place .begin is called, and it is only called when 
there is no existing Shell.

Calling text.focus_force() works for me.  .focus_set does not as the issue is 
application focus rather than widget focus within Idle.  Does this or might 
this cause any problems with Linux or Mac?

[issue24750] IDLE: Cosmetic improvements for main window


Mark Roseman added the comment:

Sounds like this one should be ready to review and incorporate.  

As a reminder, mainwin3.patch, which should work on Tk 8.4+, gets rid of the 
highlightthickness around the text widget in the editor, the sunken line/column 
effect in the status bar, and adds a thin separator below the text widget in 
the editor.

[issue24760] IDLE settings dialog shouldn't be modal


Mark Roseman added the comment:

Terry, when you get a chance, it would be great if you could have a look at 
demodalize.patch (or if you can suggest someone else who would be good to take 
a peek at it).

This is sort of the baseline for the uifactory, and touches a lot of things in 
small ways to decouple some of the inter-module dependencies. 

Other things (the new query dialogs, ttk versions of configuration and search 
dialogs, etc.) depend on this patch to wire the uifactory into the 
infrastructure.

Thanks!

New submission from Yi Ding:

Looks like this bug https://bugs.python.org/issue7111 has resurfaced in python3 
(python 2.6 works as far as I can tell) at least on Macs.

I've attached a simple test script.

Steps:
1. SSH to remote server.
2. Run nohup ./test.sh 
3. exit SSH.
4. SSH back in and see that there are a bunch of errors in your nohup.out file.

[issue24884] Add method reopenFile() in WatchedFileHandler class

2015-08-18 Thread Marian Horban


New submission from Marian Horban:

Method WatchedFileHandler::emit() makes 2 things:
1. reopens log file,
2. emits record.
Sometimes user wants to reopen file immediately after some action without 
emitting.
Code that reopens file must be moved to separate method to avoid copy-pasting 
code in programs that use this functionality.
Patch is provided.

[issue24885] StreamReaderProtocol docs recommend using private API

2015-08-18 Thread Aymeric Augustin


New submission from Aymeric Augustin:

https://docs.python.org/3/library/asyncio-stream.html?highlight=streamreaderprotocol#stream-functions
 says:

 (If you want to customize the StreamReader and/or StreamReaderProtocol 
 classes, just copy the code – there’s really nothing special here except some 
 convenience.)

StreamReaderProtocol inherits from streams.FlowControlMixin which isn't 
documented. Applying this advice means, instead of inheriting from 
StreamReaderProtocol, inheriting from streams.FlowControlMixin -- in order to 
obtain the _drain_helper method, which StreamWriter.drain must wait for.

At this point inheriting StreamReaderProtocol appears to be the lesser evil.

I suggest to remove this paragraph from the documentation.

[issue24890] Windows launcher docs don't fully explain shebang semantics

2015-08-18 Thread eryksun


eryksun added the comment:

The patch for issue 23465 (PEP 486) updated the docs to explain the behavior of 
#!/usr/bin/env as follows:

The /usr/bin/env form of shebang line has one further special
property. Before looking for installed Python interpreters, 
this form will search the executable PATH for a Python 
executable. This corresponds to the behaviour of the Unix 
env program, which performs a PATH search. 

This paragraph needs to be added to the 3.4 docs.

Another undocumented feature is adding custom commands in the [commands] 
section of py.ini. The read_commands function handles this. 

Speaking of which, a side effect of defining SEARCH_PATH in PC/launcher.c is 
that PATH is searched in find_command if the command isn't found in the global 
commands array. This can lead to unexpected behavior when combined with 
SKIP_PREFIX (i.e. the skip_prefix function skips past any of the 
builtin_prefixes in the shebang). For example, #!/usr/bin/perl will search the 
current directory and PATH for perl.COM perl.EXE, perl.BAT, etc (i.e. 
trying each extension listed in PATHEXT). This behavior should be documented. 
Preferably I think it should also be constrained to only search when the prefix 
is /usr/bin/env, such as by adding a search boolean parameter to the 
find_command function.

[issue24891] python aborts running under nohup


STINNER Victor added the comment:

I can reproduce the bug with gdb if the file descriptor 0 is closed before 
calling:
std = create_stdio(iomod, fd, 0, stdin, encoding, errors);
and after the following lines were called:
fd = fileno(stdin);
if (!is_valid_fd(fd)) {

In initstdio () at Python/pylifecycle.c:1156.

create_stdio() fails in FileIO constructor, on the line:
   if (_Py_fstat(self-fd, fdfstat)  0)
of _io_FileIO___init___impl() at Modules/_io/fileio.c:480

It's a corner case of the issue #7111, I would call it a race condition.

[issue24892] bytes.join() won't take it's own type as the argument

2015-08-18 Thread Timothy Geiser


Timothy Geiser added the comment:

I believe the special case has already been made: iterating over bytes-like 
objects returns ints. Natually, join() should take the same thing. Also, 
constructor bytearray(iterable_of_ints), the mutable-sequence expression 
ba[i:j:k] = t, and the function ba.extend(t) with t as an iterable of ints. 
It's the s.join(t) that's different than all these others.

Again:

 ba = bytearray(b'barbaz')
 ba[0:4:2] = b'ft'
 ba
bytearray(b'fatbaz')
 ba.extend(b'foo')
 ba
bytearray(b'fatbazfoo')
 ba.join(b'not_this_though')
Traceback (most recent call last):
  File pyshell#32, line 1, in module
ba.join(b'not_this_though')
TypeError: sequence item 0: expected a bytes-like object, int found


I'll go ahead argue that it's exactly backwards as is.

A fair question. The API is a private implementation for Idle (see PEP 434), 
though I am generally avoiding breaking any public uses thereof.  I actually 
checked that the method is not defined on the base class.  But on the 
microchance that someone uses it, I will restore the methods.

[issue24892] bytes.join() won't take it's own type as the argument

2015-08-18 Thread Timothy Geiser


New submission from Timothy Geiser:

You can't join bytes on another bytes object. (Everything below applies to 
bytearray, as well)


 x = b'foo'
 y = b'barbaz'
 x.join(y)
Traceback (most recent call last):
  File pyshell#2, line 1, in module
x.join(y)
TypeError: sequence item 0: expected a bytes-like object, int found


But this is fine for strings, and gives you exactly what you'd expect


 x = 'foo'
 y = 'barbaz'
 x.join(y)
'bfooafoorfoobfooafooz'
 y.join(x)
'fbarbazobarbazo'


The best work-around I could think of was


 x = b'foo'
 y = b'barbaz'
 x.join(y[i:i+1] for i in range(len(y)))
b'bfooafoorfoobfooafooz'
 y.join(x[i:i+1] for i in range(len(x)))
b'fbarbazobarbazo'


That just doesn't feel nearly pythonic enough, considering that the string 
version works as expected. I'm not even sure what the right solution here is, 
since the problem is that the iterator for a bytes object returns ints, not 
length-one bytes objects. Do we need another signature for the bytes.join 
method that takes byte-like objects and does what I'm describing here?

[issue24893] Idle occasionally gets mouse position wrong for selections

2015-08-18 Thread Raymond Hettinger


New submission from Raymond Hettinger:

Something has been wrong with the underlying Tkinter for several years. A mouse 
click to select text will mistarget by several lines.

I've held-off reporting this because I couldn't narrow it down to a 
reproduceable case.  That said, I've seen it on fresh installs of Python on 
multiple machines with different users.

But now, we have it on video.  It happened to Guido during a keynote.  See 
https://www.youtube.com/watch?v=0Ef9GudbxXY at about 7:00 to 7:30.
