[issue1767933] Badly formed XML using etree and utf-16
Serhiy Storchaka storch...@gmail.com added the comment:
Thank you, Eli.
However changes to tostring() and tostringlist() break the invariant
b.join(tostringlist(element, 'utf-16')) == tostring(element, 'utf-16'). You
should add followed methods to DataStream:
def seekable(self):
return True
def tell(self):
return len(data)
Note, that monkey-patched version is faster.
stream = io.BufferedIOBase()
stream.writable = lambda: True
stream.write = data.append
stream.seekable = lambda: True
stream.tell = data.__len__
Benchmark results:
tostring() with BytesIO:
$ ./python -m timeit -s import xml.etree.ElementTree as ET;
e=ET.XML('root/') ET.tostring(e, 'utf-16')
1000 loops, best of 3: 268 usec per loop

I plan to tackle this in two parts: - move get_source() and get_code() in importlib towards consistently raising ImportError, regardless of the reason the result couldn't be provided (chaining the exceptions to ensure details aren't lost) - update pydoc to tolerate ImportError from get_source. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15343 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

_OLD_VIRTUAL_PROMPT
}
However this prompt function does not work properly, and running
Write-Host -NoNewline -ForegroundColor Green [(py3) ]
on its own produces an error because of the lack of quotes around (py3).
Adding quotes as shown in the patch seems to fix the problem.

[issue15320] thread-safety issue in regrtest.main()
Chris Jerdonek chris.jerdo...@gmail.com added the comment: Thanks a lot for the feedback. The thinking was to use a stand-alone (even testable) construct with dependencies made explicit. For example, it wasn't obvious that the current iterator depended on forever, or whether the args_tuple parameter was a necessary part of it. But I agree it should be simplified. Here is a simpler patch, keeping iterator semantics. My preference is to avoid adding lock semantics and additional complexity directly to main(), even though doing so would permit a smaller patch. -- Added file: http://bugs.python.org/file26389/issue-15320-4.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15320 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15363] Idle/tkinter ~x.py 'save as' fails. closes idle
New submission from Terry J. Reedy tjre...@udel.edu:
I have (had ;-) a project file ~template.py with common boilerplate.
To start a new project file, I want to open the above and save as xyz.py. I can
edit and 'save' the template to update it just fine. But trying to do a 'save
as' to a new name, in Idle editor, on all three current versions, I get (when
starting Idle from command window)
Exception in Tkinter callback
Traceback (most recent call last):
File C:\Programs\Python33\lib\tkinter\__init__.py, line 1442, in __call__
return self.func(*args)
File C:\Programs\Python33\lib\idlelib\IOBinding.py, line 347, in save_as
filename = self.asksavefile()
File C:\Programs\Python33\lib\idlelib\IOBinding.py, line 514, in asksavefile
filename = self.savedialog.show(initialdir=dir, initialfile=base)
File C:\Programs\Python33\lib\tkinter\commondialog.py, line 48, in show
s = w.tk.call(self.command, *w._options(self.options))
_tkinter.TclError: user template.py doesn't exist
When starting Idle normally, this causes it to silently close. When run from
the cp interpreter, the edit window blinks but continues while the trackback is
printed in the cp window.
Just saving does not bring up a dialog; hence no problem. And I understand that
'~' has special meaning on *nix, but I am running on Windows.
I changed '~' to '@' and the file still sorts at the top (though above
__init__.py rather than below) and save as now works as it should. I know that
save as worked for this file last October, but while I think it had the same
~name then, I cannot be sure. Maybe I added '~' after the last time I
successfully used the file.
As near as I can tell, asksavefile() passes initialfile = base = '~template.py'
to savedialog.show which passes it unchanged and unexamined to tk.call. So the
special casing of ~ seems to happen in tcl/tk out of our control. I am not sure
if doing this on Windows is a tcl/tk bug or not.
For Windows, just removing '~' or even blanking the name before the .show()
might be sensible, but maybe not for *nix.
Instead, we could catch the error instead of letting it crash Idle and put up a
message box to the effect that one cannot 'save as' when editing a file named
'~'. More specifically, in IOBinding.py, line 514 or so, replace
filename = self.savedialog.show(initialdir=dir, initialfile=base)
with
try:
filename = self.savedialog.show(initialdir=dir, initialfile=base)
except TclError as e:
if e.args[0].startswith('user'):
xxx display message, click ok
filename = None
I am assuming the None is the return from canceled dialogs. Certainly, None
caused the file save code back up in saveas() (346) to skip the save.
The message could be something like tcl/tk gives special treatment to file
names starting with '~' and returned this error message {}.format(e.args[0])
We could also add else: message('unanticipated tclerror prevented save as
dialog message)

[issue15342] os.path.join behavior
Yongzhi Pan fossi...@users.sourceforge.net added the comment:
I suggest append An empty last part will result in a path that ends with a
separator or something similar to the docstring, though it is already in the
HTML documentation.
Suppose someone does this like me:
In [10]: join('a', sep)
Out[10]: '/'
He must be surprised. He has to guess how to append a separator if he does not
look at the code, or fiddle around until he finds the soultion.
Given it explained in the docstring, after he sees:
In [10]: join('a', sep)
Out[10]: '/'
He will probably look at the docstring:
In [16]: join?
Type: function
Base Class: type 'function'
String Form:function join at 0x7f053fc93ed8
Namespace: Interactive
File: /usr/lib/python2.7/posixpath.py
Definition: join(a, *p)
Docstring:
Join two or more pathname components, inserting '/' as needed.
If any component is an absolute path, all previous path components
will be discarded. An empty last part will result in a path that
ends with a separator.
Ok, he immediately knows he has to supply an empty string instead of a
separator.

[issue15233] atexit: guarantee order of execution of registered functions?
Larry Hastings la...@hastings.org added the comment: I have been meditating on this, and I'm not sure we should change 2.7. 3.2 might be okay. The thing is, I fear we're not just talking about CPython implementation details, we're talking about the Python Standard Library. The existing documentation clearly gives alternative implementations free license to call atexit registered functions in any order they like. So it's conceivable that other implementations don't guarantee reverse order. I don't know what the right thing is to do here. It seems like we could define atexit's behavior for 2.7 *if* all the major alternative implementations happily also implicitly guarantee reverse order. Failing that we probably shouldn't touch it. Or we could just document that reverse order is guaranteed in CPython only. Of course, there are no alternative implementations that support 3.2. That's why I think 3.2 might be okay. It does seem strange to redefine part of the implicit language spec more than a year after the release shipped though. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15233 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15352] importlib.h should be regenerated when the marshaling code changes
Meador Inge mead...@gmail.com added the comment: Hmmm, I guess the idempotency issue is no worse than it already is -- the same thing can still happen with trivial changes to the other prerequisites for importlib.h. Consider this small example (you might have to run sample program multiple times to see a difference): $ cat dis-closure.py import dis def adder(a, b): def add(): return a + b return add print(dis.dis(adder(1, 2).__code__)) $ ./python.exe dis-closure.py 5 0 LOAD_DEREF 0 (a) 3 LOAD_DEREF 1 (b) 6 BINARY_ADD 7 RETURN_VALUE None $ ./python.exe dis-closure.py 5 0 LOAD_DEREF 1 (a) 3 LOAD_DEREF 0 (b) 6 BINARY_ADD 7 RETURN_VALUE None The order of 'co_cellvars', 'co_varnames', and 'co_freevars' can be different from compile to compile, thus the bytecode can be different from compile to compile (I am not sure if this is worth fixing). Thus there may be times where importlib.h is regenerated, but the changes in the bytecode aren't significant. I will just commit this patch as is. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15352 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
