[issue10542] Py_UNICODE_NEXT and other macros for surrogates
Martin v. Löwis mar...@v.loewis.de added the comment: Actually, it looks like PEP 3131 and the Language Reference [1] still disagree. The latter says: identifier ::= id_start id_continue* which should probably be identifier ::= xid_start xid_continue* instead. Interesting. XID_* is being used in the PEP since r57023, whereas the documentation was added in r57824.

[issue10542] Py_UNICODE_NEXT and other macros for surrogates
Georg Brandl ge...@python.org added the comment: I think the proposal is that fixing this minefield can wait until Python 3.3 (or even 3.4, or later). That is what I was thinking. (Alex: You might not know that Martin was the main proponent of non-ASCII identifiers, so this assessment should have some weight.) I'm thinking about an approach of a variable representation: one, two, or four bytes, depending on the widest character that appears in the string. I think it can be arranged to make this mostly backwards-compatible with existing APIs, so it doesn't need to wait for py4k, IMO. OTOH, I'm not sure I'll make it for 3.3. That is an interesting idea. I would be interested in helping out when you'll implement it. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10542 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10796] readline completion flaw
New submission from rheise ralfhe...@freenet.de:
Python's readline library generates out of the choices provided by a custom
completion function the wrong terminal input. Say, the completion function
suggests 'foobar' and 'foobaz' as matching completion strings, readline should
produce the characters 'fooba' to prompt and await further interaction by the
user.
This is the intended behaviour of readline and this works in Python as well.
However this does nod work anymore as soon, as the suggestion
list contains dashes `-' as input argument.
A working as supposed example:
import readline
def complete(text, state):
... if (state == 0):
... return abc
... if (state == 1):
... return ade
... else:
... return None
...
readline.parse_and_bind(Tab: complete)
readline.set_completer(complete)
raw_input()
a
abc ade
a
'a'
remark: I entered a and hit tab. readline produces abc/ade as valid choices,
stopping at the first ambiguous character. Now consider the following example:
import readline
def complete(text, state):
... if (state == 0):
... return a-bc
... if (state == 1):
... return a-de
... else:
... return None
...
readline.parse_and_bind(Tab: complete)
readline.set_completer(complete)
raw_input()
a-a-a-
'a-a-a-'
The intended behaviour is the very same as for the first example. Readline
should produce 'a-' and offer a-bc and a-de as valid choices. Instead it
produces an additional a- for every time I hit tab.
Same for Python3.1:
$ python3.1
Python 3.1.2 (release31-maint, Sep 26 2010, 13:51:01)
[GCC 4.4.5] on linux2
Type help, copyright, credits or license for more information.
import readline
def complete(text, state):
... if (state == 0):
... return a-bc
... if (state == 1):
... return a-de
... else:
... return None
...
readline.parse_and_bind(Tab: complete)
readline.set_completer(complete)
input()
a-a-a-a-a-
'a-a-a-a-a-'
Other programming languages falling back to the GNU C-readline library don't
have this problem. Consider the roughly equivalent example in Perl which works
as expected:
use Term::ReadLine;
sub complete
{
my ($text, $state) = @_;
if ($state == 0)
{
return a-bc;
}
elsif ($state == 1)
{
return a-cd;
}
else
{
return undef;
}
}
my $term = new Term::ReadLine 'sample';
my $attribs = $term-Attribs;
$term-parse_and_bind(Tab: complete);
$attribs-{completion_entry_function} = \complete;
$term-readline();
Running it:
$ perl rl
a-
a-bc a-cd
a-

[issue6210] Exception Chaining missing method for suppressing context
Patrick W. p...@borntolaugh.de added the comment: Nick Coghlan (ncoghlan) at 2010-12-29 08:46 (UTC): No, the context must always be included unless explicitly suppressed. Then there should be some actually working way to suppress it, right? I think the standard behaviour that automatically sets the `__context__` of an exception is fine, especially when thinking about exceptions that get raised inside `except` blocks and are not custom made. However there should be some way to suppress the context in some way. Personally, I would prefer if `raise .. from ..` would set the exception's cause, but would *not* automatically print that cause. But then again, it would be a problem to get the cause afterwards when the program terminated because of that exception. So obviously, in such situations, both the cause and the context of a raised exception cannot be used (because both prints out the full trackback). So we obviously need some new mechanism or syntax to ignore the previous exception. As it seems that the cause has a higher precedence than the context (which is fine as the cause is changeable), using `None` as the cause of an exception would be the best solution in my opinion: try: x / y except ZeroDivisionError as e: raise Exception( 'Invalid value for y' ) from None While it might be difficult as the cause is `None` before and gets set to `None` afterwards, Python is totally able to detect that the value was explicitely set to `None`. Either the raise statement should set some internal flag, or the setter for `__cause__` should just check when it is first written to. If that would be too complicated (although it would be possible and very logically to do it like that), maybe a different syntax would work: try: x / y except ZeroDivisionError as e: raise Exception( 'Invalid value for y' ) instead Something like that. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6210 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

So unless someone claims that this is a security issue (and Barry agrees) or reports that this particular issue appears in a current version (2.7.1, 3.1.3, 3.2) separate from other open Apple/Tk/IDLE issues, this should be closed. -- nosy: +terry.reedy ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6864 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10799] Improve webbrowser.open doc (and, someday, behavior?)
New submission from Terry J. Reedy tjre...@udel.edu:
webbrowser.open (and two aliases):
1. document return value, which seems to be: True if a browser tab or window is
opened, regardless of whether or not the url is found; False otherwise.
2. document that (on Windows, at least) the default browser only gets used if a
non .htm(l) url starts with 'www' or 'http:'.
This is true because os.startfile(url) apparently only works if above is true,
as required for the Start/Run box to recognize an entry as a url.
In particular, I have Firefox as default and 'www.google.com' and
'http://bugs.python.org' get opened in Firefox (new tab as requested). However,
'google.com' and 'bugs.python.org' open with IE after some delay. [Start/run
either opens with Firefox or reports 'cannot find'.]
-
In the longer run, what I would really like is for webbrowser to be better at
using the default or finding executables.
I thought of adding 'http://' if not present but that would disable opening
files in a file browser.
I suspect there is a registry entry but do not know what it is. That would also
pick up new browswers like Chrome.
It seems to me that the current behavior is a 'limitation' in this code:
# Detect some common Windows browsers, fallback to IE
iexplore = os.path.join(os.environ.get(PROGRAMFILES, C:\\Program Files),
Internet Explorer\\IEXPLORE.EXE)
for browser in (firefox, firebird, seamonkey, mozilla,
netscape, opera, iexplore):
if _iscommand(browser):
register(browser, None, BackgroundBrowser(browser))
Firefox is not being recognized as a command because _iscommand('firefox') does
not not see firefox.exe as an executable because it only checks _isexecutable()
in the hodgepodge list of paths in PATH. At one time (but no longer),
executables were ofter put in c:/windows, which by default is in PATH.
Since you hardcoded the default real path for iexplore (C:\\Program
Files\\Internet Explorer\\IEXPLORE.EXE), you could do the same for other
programs:
firefox = os.path.join(os.environ.get(PROGRAMFILES, C:\\Program Files),
Mozilla Firefox\\firefox.exe)

[issue6285] Silent abort on XP help document display
Terry J. Reedy tjre...@udel.edu added the comment: webbrowser appears to be designed to return True/False if it does/or not open a browser window (regardless of site response). (I opened #10799 for a doc addition.) I believe an exception would likely indicate a bug therein. So I only wrapped the Windows startfile call (and only catch WindowsError), which could fail with any bad entry, and not just one left over from a previous install. This patch should make the behavior on Windows much like on other systems: display message and move on. I have (yet) not tested this (but may try to), but take Scott's and Amaury's claims that the message call is correct. I will commit in a week if there are no objections. -- assignee: - terry.reedy keywords: +patch stage: - commit review type: - behavior versions: +Python 2.7, Python 3.2 Added file: http://bugs.python.org/file20199/z6285.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6285 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
