bdb.py now has a class definition called Breakpoint along with
associated methods. There's no reason why this class has to
be there; if you prefer it elsewhere, 'tis easily done.
(Minor reformatting by GvR; e.g. moved Breakpoint's doc string to
proper point.)
cmd.py has incorporated the changes we discussed a couple of weeks ago
(a command queue, returning line from precmd, and stop from postcmd)
and some changes to help that were occasioned because I wanted to
inherit from pdb which inherits from cmd.py and the help routine
didn't look for commands or the associated help deeply enough.
1. use dict.get instead of try/except KeyError
2. if the url scheme is 'http' then avoid the series of
'if var in [someseq]:'. instead, inline all of the code.
3. find = string.find
1) I added a command queue which is helpful to me (at least so far) and
would also allow syntax like 's;s' (step; step) in conjunction with precmd
2) doc_leader allows the derived class to print a message before the help
output. Defaults to current practise of a blank line
3) nohelp allows one to override the 'No help on' message. I need
'Undefined command: "%s". Try "help".'
4) Pass line to self.precmd to allow one to do some parsing: change first
word to lower case, strip out a leading number, whatever.
5) Pass the result of onecmd and the input line to postcmd. This allows
one to ponder the stop result before it is effective.
6) emptyline() requires a if self.lastcmd: conditional because if the
first command is null (<cr>), you get an infinite recursion with the
code as it stands.
by the new '-x' arguments, losing the previous items. Thus,
test_support, test_b1 & test_b2 are executed (and warnings issued).
(Discovered by Vladimir Marangozov.)
instead of a list, turn it into a list containing that string. This
avoids an apparently common newbie mistake -- passing in a single
string for the destination and have it treated as a sequence of
characters.
displays funny characters, like spaces or control characters, more
clearly (one of my pet peeves in error messages). Also only suppress
the filename if it is None; display it if it is '', since that would
be a genuine (illegal) filename passed in!
how to exit (in a platform dependent way!). We use os.sep to
determine which platform we're on, since I expect that this will work
better for minority platforms.

the "initialcolor" code is broken in several places in the
current version of tkColorChooser. I've attached an up-
dated version for 1.5.2.
DOS (as well as OS/2). I presume that making a call to putenv() with
a lowercase key will actually do the right thing. I know this is so
on Windows/DOS, and I expect it is so OS/2 -- but the old OS/2 code
didn't assume this. (I don't know if the person who provided the OS/2
patch was clueless or just didn't care about DOS and Windows.)
Also ripped out the support for pickling -- as of 1.5, this is no
longer needed to make pickling work.
I did some bugfixes, and fixed a major problem with the esmtp suport (I
think the person who did that part misunderstood RFC1869) Some of the
interface fer esmtp-related things has changed as a result.
I also added some documentation to the SMTP class' docstring.
choice(range(start, stop, step)) but faster. This addresses the
problem that randint() was accidentally defined as taking an inclusive
range (how unpythonic).
The code is longish because Tim Peters insisted that it reject
non-integral arguments while I insisted that it be not much slower
than randint(); the compromise satisfies both but is somewhat
convoluted.
Also changed randint() to be implemented through randrange(). This is
a semantic change because old randint() didn't test its arguments for
validity. (It also makes randrange() win any contest with randint()
:-)
involve a filesystem path. To that end:
- Changed IOError to EnvironmentError and added a hack which checks
for arg of len 3. When constructed with a 3-tuple, the third item
is the filename and this is squirreled away in the `filename'
attribute. However, for in-place unpacking backwards
compatibility, self.args still only gets the first two items. Added
a __str__() which prints the filename if it is given.
- IOError now inherits from EnvironmentError
- New class OSError which also inherits from EnvironmentError and is
used by the posix module.
Fix the implementation of quote_plus(). (It wouldn't treat '+' in the
original data right.)
Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions. Also added a helper method lookupmodule().
Also:
- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.
not calling self.search(); instead, call self.code.match() directly
and interpret the list of registers it returns directly. This saves
the overhead of instantiating a MatchObject for each hit, basically
inlining search() as well as group(). When a MatchObject is still
needed, one is allocated and reused for the duration of the scan.
In the bbox method of Group (Canvas.py file), you should read
return self.canvas._getints(self._do('bbox'))
instead of
return self._getints(self._do('bbox'))
(2) Made the test script a bit fancier -- you can now use it to run
arbitrary scripts in restricted mode, and it will do the right thing.
(The interactive mode is still pretty lame; should integrate this with
code.interact().)
1. Convert to using re module
2. Added two new exception classes
a. MissingSectionHeaderError which signals an early parsing
exception when options appear in the file before any section
header. Previously a bogus TypeError was thrown deeper down.
b. ParsingError which collates any non-fatal parsing errors.
ConfigParser.read() will raise this after the entire file was
parsed if any errors occurred during parsing (client could just
catch the exception and continue, because the ConfigParser
instance would still be initialized with the valid data).
(small note: Error.__msg => Error._msg)
3. ConfigParser.__read() now uses re which has the following minor
semantic change: underscore is now allowed in section header and
option name. Also, because of the old regexps, theoretically.
Fixed continuation line bug reported by F. Lundh.
4. It seemed that the old ConfigParser automatically added the option
`name' to every section, which contained the name of the section.
This seemed bogus to me so I took it out.
string. Added groupdict() to MatchObject -- return the named groups
as a dict. Added default argument to groups() to specify what to
return for unmatching groups; groupdict() also has this.
the tty and the caller can deal with the interrupt.
In the windows version, recognize ^C and raise KeyboardInterrupt (not
sure if this is needed, but can't hurt).
should only be set to application/x-www-form-urlencoded when the
method is POST. E.g. for PUT, an empty default (defaulting to
text/plain later) makes more sense.
- explain seekable
- when seekable==1, test fp.tell() and set it to 0 if that fails
- support overridable method iscomment(line) to weed out comments
- check for unread() method on file object before trying to seek
And one of my own:
- Add a get() method which behaves like a dictionary's get(); this is
actually implemented by giving getheader() an optional second argument
to specify the default, and aliasing get to getheader.
The 1.5.1 tabnanny.py suffers an assert error if fed a script whose last
line is both indented and lacks a newline:
if 1:
print 'oh fudge' # no newline here:
The attached version repairs that.
- Handle <? processing instructions >.
- Allow . and - in entity names.
Also fixed an oversight in the previous fix (in one place, [ \t\r\n]
was used instead of string.whitespace).

Following is a context diff for imaplib.py in the Python1.5.1 distribution.
It fixes 2 bugs. One to do with argument quoting, and the other to do with
caching of un-tagged responses. Apologies for its size.
problem was a couple of bugs in the readline implementation.
1. Include the '\n' in the string returned by readline
2. Bug calculating new buffer size in _unread
Also remove unncessary import of StringIO

I think I found a bug in CGIHTTPServer.py. (Does anyone care? :-)
I was trying to use it as the web server for uploading files.
Python CGI scripts (using the CGI module) that worked for other
servers (e.g., Netscape Enterprise server) hang when run from
CGIHTTPServer. The problem is that the content type parameters,
in particular the boundary parameter, were not passed through to
the CGI scripts, thus making the MIME parsing code choke.
My simple-minded fix is:
% diff CGIHTTPServer.py /usr/local/lib/python1.5/CGIHTTPServer.py
137,140c136
< if self.headers.typeheader is None:
< env['CONTENT_TYPE'] = self.headers.type
< else:
< env['CONTENT_TYPE'] = self.headers.typeheader
---
> env['CONTENT_TYPE'] = self.headers.type

and the "key" keyword parameter was used to invoke .go(), use the directory
of the selected file as the stored directory to return to when the same key
is used again. This is useful since the user may well entry at least part
of the path in the filename box instead of doing a lot of clicking around in
the listboxes.
as soon as I change things even just a little bit? :-) Even works

by complaints from, and correct operation verified by, Nigel O'Brian.
wm_title(), etc. The old names (title() etc.) are still defined as
aliases.
This brings all methods up to use the same naming convention: whether
the Tcl syntax is
.window.path.name command subcommand [options]
or
command subcommand .window.path.name [optins]
the Python equivalent is always
windowobject.command_subcommand(options)
calling self.tk.getint() and self.tk.getdouble(), call the globals
getint() and getdouble(), which in turn are just names for the Python
builtins int() and double(). (Making them globals actually save a
dict lookup compared to using the built-in.) The corresponding
methods of class Misc have been changed similarly. (Note that
getboolean() hasn't been changed because there's no Python
equivalent.)
The use of int() and float() has another advantage: if/when Tcl calls
can actually return Tcl objects with other types than string, use of
int() and float() is essential.
not needed to say apply(self.tk.call, t); self.tk.call(t) has the same
effect. This cuts down tremendously on the number of apply() calls
made. No measurable effect, but at the very least it saves the lookup
of apply() in the globals!
be more intelligent when the database already exists (use the module
for the existing file, according to whichdb). Noted in the doc
strings that there doesn't seem to be a different between 'c' and 'n'.
