[issue24896] It is undocumented that re.UNICODE affects re.IGNORECASE
New submission from Leif Arne Storset: A non-ASCII string does not match a regular expression case-insensitively unless the UNICODE flag is set. This seems reasonable, but the documentation seems to imply that this is not the case. The example: import re # Does not match re.compile(uнеоднозначность, re.IGNORECASE) \ .findall(uНеоднозначность) # Matches re.compile(uнеоднозначность, re.IGNORECASE | re.UNICODE) \ .findall(uНеоднозначность) (In Python 3, it does not match if re.ASCII is given.) The documentation (2.7) says: re.UNICODE Make \w, \W, \b, \B, \d, \D, \s and \S dependent on the Unicode character properties database. (https://docs.python.org/2/library/re.html#re.UNICODE) My regex does not use any of those escapes, yet the regex changes behavior with the UNICODE flag. This leads to confusion when the regex doesn't match. The documentation is very specific about the behavior that changes with the flag, implying that behavior not mentioned is unaffected. Of course, it's easy to guess the correct (hopefully) solution. Still, I suggest changing the documentation to mention that re.IGNORECASE is affected. Looking at the source code, there seems to be further consequences (it mentions Unicode locale) which may also warrant a mention. If you do want to avoid specifics, however, even a hand-wavy reference to something like match according to Unicode would help, because it implies that not only the escapes change behavior. In Python 3, there is a counterpart to the 2.7 problem: re.ASCII makes our Cyrillic string not match. Again, this behavior makes intuitive sense, but the documentation seems to indicate something different: re.ASCII Make \w, \W, \b, \B, \d, \D, \s and \S perform ASCII-only matching instead of full Unicode matching. This is only meaningful for Unicode patterns, and is ignored for byte patterns. … re.IGNORECASE Perform case-insensitive matching; expressions like [A-Z] will match lowercase letters, too. This is not affected by the current locale and works for Unicode characters as expected. re.ASCII does appear to affect re.IGNORECASE. Since this is the non-default case, however, I'm not sure it's worth calling it out. I'd be happy even if only the 2.7 docs change. -- assignee: docs@python components: Documentation messages: 248829 nosy: Leif Arne Storset, docs@python priority: normal severity: normal status: open title: It is undocumented that re.UNICODE affects re.IGNORECASE versions: Python 2.7, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24896 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

If we make it load ucrtbase.dll directly (which does still have named exports, and also uses the API schema on Windows 10): * some code that uses it will need updating (due to API changes since VC9/VC10) * code may need to change depending on OS updated (which could change the ucrtbase exports) * much existing code using this will probably work If we leave it as is: * all existing uses will obviously fail, nothing subtle * users will either substitute the name themselves, find an equivalent stdlib function, or use a supported Windows API Having just written that out, I still think not supporting it is best, but I do need to write it up in the porting info still.

[issue24892] bytes.join() won't take it's own type as the argument
R. David Murray added the comment: I said *enough* motivation. doing b'x'.join(b'anything') is a very uncommon operation (as is the equivalent string case). There is no parallel to the bytearray constructor, since that constructor does not take an iterable of byte-like objects as its input, it takes an iterable of ints, as you point out. There is no parallel to slice assignment, since a slice is by definition a bytes like object (that's why using the slice notation in the comprehension to the argument of join works). The inconsistency is entirely a consequence of the fact that if you iterate a bytes-like object you get integers. So, join's behavior is consistent with that, and as I said, *I* don't see enough motivation to make a special case exception here. Others may disagree. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24892 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Terry J. Reedy added the comment: NEWS patches should be omitted from submitted .diff or .patch files because a) NEWS is so volatile that merge conflicts applying the .diff are likely; b) NEWS is different between versions, so that forward merge conflicts are possible (usual for Idle items, so I apply them separately) and b) committers tend to rewrite then anyway. I will later prepare and separately commit one entry for this issue. ACKS is more stable within and between versions, so including a acks patch is ok. But then the patch must be prepared for 3.4 and 2.7 specifically, and I want to know ahead of time if there will be a 3.4 to 3.5 or 3.5 to 3.6 merge conflict. You can include it or leave it out (easier). I tested both the .patch and diff in msg248849. When putting code or diffs in messages, please include function/class/method names or lineno. With this patch, SubList always return a list of one item. Note that we can always use frame.f_locals, whether it is or is not f_globals. I am not exactly sure what you meant by your your last question, but it lead me to the answer. When a tree item with + is clicked, the corresponding GetSubList method is called. What we want FrameTreeItem.GetSubList to do, instead of returning a list of (now 1) VariablesTreeItem, is to return what VariablesTreeItem.GetSubList would (when clicked subequently). Replace most of the body of the former (FrameTI.GSL) with the body of the latter (VarTI.GSL), with 'self.object' replaced by 'frame.f_locals'. Class VariablesTreeItem will then be obsolete. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24790 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8987] Distutils doesn't quote Windows command lines properly
Steve Dower added the comment: Switching distutils.spawn to simply use subprocess.Popen (probably keeping the explicit path search) looks good to me. Quoting rules are different when you call with shell=True (aka cmd.exe /c), since then you also need to escape ^, | and (with a ^), but if it's being passed directly to the process (via CreateProcess) you don't need to do this. Popen doesn't appear to handle this correctly either. Because of the backwards compatibility concerns, realistically I think we can only fix this in 3.6 at this stage. The issue has existed for too long to convince Larry to take it for 3.5.0, and changing the behaviour of either distutils or subprocess between .0 and .1 feels risky to me. (Adding Brett in case he's motivated to take the opportunity to definitively learn and implement Windows's quoting rules and becoming the first person in the world to achieve it.

[issue24889] Idle: always start with focus
Mark Roseman added the comment: I reproduced your problem on Windows, and verified that it wasn't an issue on either Mac or Linux. Your fix however, didn't change anything for me (on a Windows 7 VM). I tried a few other things (raising the window, playing with various wm attributes, etc.) with no luck. The fact that it works ok when run directly from the command prompt got me thinking, and I eventually tracked down what is preventing IDLE from becoming the front application. It's actually an internal Windows feature, that's designed to prevent background applications from all of a sudden putting up windows that interfere with what you're doing in the foreground, instead putting a notification in the task bar and making you click that or the window itself. The mechanism used is to prevent applications from coming to the front on their own if they don't do so very shortly after they're first launched. So when you launch a Python shell (e.g. from a command prompt), the delay it takes you to type import idlelib.idle plus the launch time exceeds this timeout, and Windows decides it won't allow it to put the window in the foreground. You can change the timeout (or set it to 0 to disable the feature) via the registry key HKEY_CURRENT_USER\Control Panel\Desktop\ForegroundLockTimeout (you need to restart after). With that change, your fix worked for me. You can Google around for ForegroundLockTimeout for additional info. There's not realistically an easy way to get around it in IDLE itself (for obvious reasons, given the purpose of the feature). I'm guessing this will affect few people as much as it does you, constantly starting and stopping IDLE from within Python. If the fix works on your system, especially without mucking with that registry key, that should cover it. The fix doesn't cause any harm on Mac or Linux. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24889 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8987] Distutils doesn't quote Windows command lines properly
R. David Murray added the comment: There are two features of this I have questions about. If I'm understanding correctly, if passed a quoted string you are not re-quoting it, but you are always stripping a trailing slash even if it is inside quotes. For the first, that seems wrong. Either we should be quoting the quotes, or we should assume that if passed a string that starts and ends with quotes, that it is already fully quoted, and not change it. For the second, doesn't that potentially change the semantics of the string passed in? You can't actually know that the backslash is part of a path, nor can you be sure that a trailing backslash is not significant even if it is a path. And in fact if there is a backslash before a double quote, arguably that is supposed to be a double quote that doesn't end the string (see point one above). I tried list2cmdline, and what it does is to backslash escape appropriately, including preserving blackslashes that are in front of double quotes, and does not add surrounding quotes if there are no internal blanks. I think list2cmdline is correct here (and it has certainly seen a lot of use), and I think we should either replicate its logic or just use it. Now, subprocess calls CreateProcess, while distutils calls os.spawnv, but my understanding is that the quoting rules are the same (that is, that the CRT's _spawnv ultimately calls CreateProcess with the arguments joined by blanks). Since issue 8972 has been resolved by fixing the broken behavior, I think we should just use list2cmdline. We could leave _nt_quote_args alone and replace the call to it in _spawn_nt with: cmd = [list2cmdline([arg]) for arg in cmd] or we could put the fix in _nt_quote_args. The backward compatibility calculus is...not obvious :( -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8987 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8987] Distutils doesn't quote Windows command lines properly
Mark Lawrence added the comment: As far as I'm concerned distutils on Windows is a farce so do what you like with it. It usually can't pick up the version of VS that you know is correct and is installed, the error messages are less than useless, so the only damage that I see is something that is even more broken than it all ready is. Alternatively it gets slightly further before bombing with yet another useless message. -- nosy: +BreamoreBoy ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8987 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24897] Add new attribute decorator (akin to property)?
New submission from Emanuel Barry: This is an issue that came up quite often when creating code where you want the class' namespace to hold the instance attributes. I've often seen (and written) code like this: class Foo: def __init__(self): self._x = 42 @property def x(self): return self._x As an attempt to populate the class namespace with what should normally be available on the instance. In all my projects now I use my own custom decorator to get around that. class attribute: def __init__(self, func): self.func = func def __get__(self, instance, owner): if instance is None: return self return self.func.__get__(instance, owner) This permits instances to override attributes set as such, like this: class Bar: def __init__(self): self.x = 42 @attribute def x(self): pass # placeholder I figured I might as well suggest the idea. I'm not attached to the name, and it's more for completion's sake rather than hard necessity. -- messages: 248869 nosy: ebarry priority: normal severity: normal status: open title: Add new attribute decorator (akin to property)? versions: Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24897 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24897] Add new attribute decorator (akin to property)?
Emanuel Barry added the comment: The only significant difference is that it lets the instance overwrite the attribute (it doesn't have __set__ or __delete__). For example (using fractions.Fraction to demonstrate), the following: def __new__(cls, numerator=0, denominator=None, _normalize=True): # ... self._numerator = numerator self._denominator = denominator @property def numerator(a): return a._numerator @property def denominator(a): return a._denominator would become: def __new__(cls, numerator=0, denominator=None, _normalize=True): # ... self.numerator = numerator self.denominator = denominator @attribute def numerator(a): pass @attribute def denominator(a): pass This is more of an aesthetic enhancement rather than a functional one. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24897 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24898] Documentation for str.find() is confusing
New submission from Ted Lemon: The documentation for str.find() on python.org, for all current versions, says: Return the lowest index in the string where substring sub is found, such that sub is contained in the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found. I think that what is meant here is this: Return the lowest index in a string s where substring sub is found, such that if a is the returned index, and b == a + len(sub), sub is contained in the slice s[a:b]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found. -- assignee: docs@python components: Documentation messages: 248872 nosy: Ted Lemon, docs@python priority: normal severity: normal status: open title: Documentation for str.find() is confusing versions: Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24898 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24893] Idle occasionally gets mouse position wrong for selections
Mark Roseman added the comment: Watched that video clip - yikes, that is bad. I tried playing around to reproduce it, but haven't had any success yet, though did find another weird thing. If you have a bunch of short lines without any blanks, sometimes when you click well to the right of all of them, the cursor will end up at the beginning of one of the lines, rather than at the end of them. This wasn't consistent but did happen maybe 1/10th of the time. Guido was running on a Mac. Were the other examples where you saw this missing by several lines also all on Mac?

[issue24893] Idle occasionally gets mouse position wrong for selections
Ned Deily added the comment: A wild guess: could it be dependent on the screen resolution, in particular if a Mac Retina display is in use? It also could depend on the version of Tk; from the screenshot it is clear that Guido was not using a python.org version of 3.4 so the out-of-date Apple-supplied Tk *might* be in use. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24893 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24893] Tk occasionally mispositions Text() insert cursor on mouse click.
Terry J. Reedy added the comment: Guido, we are looking at the PyCon 2014 keynote video where the text cursor was misplaced relative to the mouseclick, trying to guess the reason. Do you still have the Mac laptop you used? If so, have you upgraded its python? The hideous moment is at 7:10. Guido clicked after '.split' to position the blinking insert cursor there, to add 'lines' to the method name. There was no reason to select anything. The cursor appeared instead on the blank line 4 lines above. Guido was able to move the text cursor with arrow keys, as normal, to the desired position. Serhiy or Kevin, have either of you seen or heard of this problem? Earlier in the video, there are Display boxes offering resolution choices of 800x600, 1024x768, and 1280x1024. I presume that this indicates 'not Retina'. I suspect the OS or tk they jointly control the text cursor. Minimal code for experiments is: import tkinter as tk root = tk.Tk() text = tk.Text() text.pack() root.mainloop() Running the above on Win7, I tried Mark's experiment. Clicking near the end of a line consistently put the cursor at the end of the line. Clicking near the right edge of the box, at least 50 columns away, consistently put the cursor at the beginning of *some* line, but not necessarily the one 'clicked' on. I looked at idlelib.EditorWindow for anything that might possibly affect tk processing of left button clicks. I only found 2 items. if macosxSupport.isAquaTk(): text.bind(Control-Button-1,self.right_menu_event) If the problem were Mac-specific, this might warrant a look. self.text.event_add(set-line-and-column, KeyRelease, ButtonRelease) The cursor is positioned on buttom press, before release. -- assignee: terry.reedy - components: +Tkinter nosy: +gvanrossum, serhiy.storchaka, wordtech stage: - test needed title: Idle occasionally gets mouse position wrong for selections - Tk occasionally mispositions Text() insert cursor on mouse click. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24893 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24870] Optimize coding with surrogateescape and surrogatepass error handlers
INADA Naoki added the comment:
Why are bytes being escaped in a binary blob? The reason to use
surrogateescape is when you have data that is mostly text, should be
processed as text, but can have occasional binary data. That wouldn't seem
to apply to a database binary blob.
Since SQL may contain binary data.
data = bytes(range(256))
cursor.execute(uINSERT INTO t (blob_col) values (%(data)s), {data: data})
DB driver should escape properly for SQL syntax, then decode with
surrogateescape for % operator.
bytes in Python 3.5 supports % operator so I can use it instead of unicode %.
But I'll continue to support Python 3.4 for some years.
