guess the mime type of a local file.
Change suggested by Sjoerd (with different implementation):
when retrieve() creates a temporary file, preserve the suffix.
Corrollary of the first change:
also return the mime type of a local file in retrieve().
"self.dict.close()" and ignore the exception. The "if self.dict:"
part would be calculated through len(self.dict.keys()), which is very
expensive for a large dictionary...
disturbing the current exception, and returning tb.tb_lineno, which is
the line number of thr traceback, rather than the current line number.

Miller, who complained that its kurtosis was bad, and then fixed by
Lambert Meertens (author of the original algorithm) who discovered
that the mathematical analysis leading to his solution was wrong, and
provided a corrected version. Mike then tested the fix and reported
that the kurtosis was now good.
(2) Fix normcase() to use string.lower() and string.replace() -- it
turns out that the table constructed for translate() didn't work in
locales that have a different number of lowercase and uppercase
letters.
First, the RNG in whrandom.py sucks if you let it seed itself from the time.
The problem is the line:
t = int((t&0xffffff) | (t>>24))
Since it ORs the two parts together, the resulting value has mostly
ON bits. Change | to ^, and you don't lose any randomness.
most recently opened URL in self.openedurl of the URLopener instance.
This doesn't really work if multiple threads share the same opener
instance!
Fix: openedurl was actually simply the type prefix (e.g. "http:")
followed by the rest of the URL; since the rest of the URL is
available and the type is effectively determined by where you are in
the code, I can reconstruct the full URL easily, e.g. "http:" + url.
The main incompatibility is that the error reporting method is now
called as
parser.syntax_error(msg)
instead of
parser.syntax_error(lineno, msg)
This new version also has some code to deal with the <?xml?> and
<!DOCTYPE> tags at the start of an XML document.
The documentation has been updated, and a small test module has been
created.
Here's my suggested replacement for gzip.py for 1.5.1. I've
re-implemeted methods readline and readlines, added an _unread, and
tweaked read and _read.
I tried a more complicated buffer scheme for unread (using a list of
strings and string.join), but it was more complicated and slower.
This version is a lot faster than the current version and is still
pretty simple.
Fixed problems when unpickling in restricted execution environments.
These methods try to assign to an instance's __class__ attribute, or
access the instances __dict__, which are prohibited in REE. For the
first two methods, I re-implemented the old behavior when assignment
to value.__class__ fails.
For the load_build() I also re-implemented the old behavior when
inst.__dict__.update() fails but this means that unpickling in REE is
semantically different than unpickling in unrestricted mode.
input. When an EOF is read, break out of the loop instead of (by
default) writing an empty line (which doesn't do much good). Don't
close self when falling through the loop.
* The invoke methods of the three Tkinter widgets Button,
Checkbutton and Radiobutton should return the value returned by
the callback, (like the Menu widget does):
def invoke(self):
return self.tk.call(self._w, 'invoke')
* The select_from method of the Canvas widget should use 'from', not
'set':
def select_from(self, tagOrId, index):
self.tk.call(self._w, 'select', 'from', tagOrId, index)
Currently, if you use select_from, you get the error message:
'TclError: bad select option "set": must be adjust, clear, from, item, or to'
* The 'entrycget' and 'type' methods of the Tk menu widget are
missing from Tkinter.
* There is a bug in grid_columnconfigure and grid_rowconfigure. For
example, this should return the current value of the 'minsize'
option for column 0:
f.grid_columnconfigure(0, 'minsize')
Instead it returns the same as:
f.grid_columnconfigure(0)
I suggest that the hint given in the comment in the
Tkinter.Misc.configure method should be followed - "ought to
generalize this so tag_config etc. can use it". Repeating the
same configure code several times in Tkinter is inviting errors.
[I did not follow this advice --G]
* The grid_slaves method should handle options. Currently, to pass
options to the grid_slaves method, you have to do something like:
grid_slaves('-row', 1)
retrieving files from the same host and directory, you had to close
the previous instance before opening a new one; and retrieving a
non-existent file would return an empty file. (The latter fix relies
on maybe an undocumented property of NLST -- NLST of a file returns
just that file, while NLST of a non-existent file returns nothing. A
side effect, unfortunately, seems to be that now ftp-retrieving an
*empty* directory may fail. Ah well.)
