automatically delete the bindings for that item. Since there's

The application where Signum Support uses smtplib needs to be able to
report good error messages to the user when sending email fails. To
help in diagnosing problems it is useful to be able to report the
entire message sent by the server, not only the SMTP error code of the
offending command.
A lot of the functions in sendmail.py unfortunately discards the
message, leaving only the code. The enclosed patch fixes that
problem.
The enclosed patch also introduces a base class for exceptions that
include an SMTP error code and error message, and make the code and
message available on separate attributes, so that surrounding code can
deal with them in whatever way it sees fit. I've also added some
documentation to the exception classes.
The constructor will now raise an exception if it cannot connect to
the SMTP server.
The data() method will raise an SMTPDataError if it doesn't receive
the expected 354 code in the middle of the exchange.
According to section 5.2.10 of RFC 1123 a smtp client must accept "any
text, including no text at all" after the error code. If the response
of a HELO command contains no text self.helo_resp will be set to the
empty string (""). The patch fixes the test in the sendmail() method
so that helo_resp is tested against None; if it has the empty string
as value the sendmail() method would invoke the helo() method again.
The code no longer accepts a -1 reply from the ehlo() method in
sendmail().

Mostly I just re-added the SMTPRecipientsRefused exception

I pondered the change of the return values to tuples all around,
and after some thinking I decided that regularizing the return values was
too much of the Right Thing (tm) to not do.
My one concern is that code expecting an integer & getting a tuple
may fail silently.
(i.e. if it's doing :
x.somemethod() >= 400:
expecting an integer, the expression will always be true if it gets a
tuple instead. )
However, most smtplib code I've seen only really uses the
sendmail() method, so this wouldn't bother it. Usually code I've seen
that calls the other methods usually only calls helo() and ehlo() for
doing ESMTP, a feature which was not in the smtplib included with 1.5.1,
and thus I would think not much code uses it yet.

philosophical problem -- to me, the split*() functions are purely
syntactical, and the fact that \\foo is not a valid path doesn't mean
that it shouldn't be considered an absolute path.)

the effect is to concatenate the two chunks of data.

If a filename on Windows starts with \\, it is converted to a URL
which starts with ////. If this URL is passed to urlparse.urlparse
you get a path that starts with // (and an empty netloc). If you pass
the result back to urlparse.urlunparse, you get a URL that starts with
//, which is parsed differently by urlparse.urlparse. The fix is to
add the (empty) netloc with accompanying slashes if the path in
urlunparse starts with //. Do this for all schemes that use a netloc.
Pathnames of files on other hosts in the same domain

The URL should be something like file:////host/path/to/file.

netloc from the base url as the default netloc for the resulting url
even if the schemes differ.
Once upon a time, when the web was wild, this was a valuable hack
because some people had a URL referencing an ftp server colocated with
an http server without having the host in the ftp URL (so they could
replicate it or change the hostname easily).
More recently, after the file: scheme got added back to the list of
schemes that accept a netloc, it turns out that this caused weirdness
when joining an http: URL with a file: URL -- the resulting file: URL
would always inherit the host from the http: URL because the file:
scheme supports a netloc but in practice never has one.
There are two reasons to get rid of the old, once-valuable hack,
instead of removing the file: scheme from the uses_netloc list. One,
the RFC says that file: uses the netloc syntax, and does not endorse
the old hack. Two, neither netscape 4.5 nor IE 4.0 support the old
hack.
An attempt to execute grid_slaves with arguments (0,0) results in
*all* of the slaves being returned, not just the slave associated with

rather just whether is evaluates to non-false. A value of 0 fails

File names with "funny" characters get translated wrong by
pathname2url (any variety). E.g. the (Unix) file "/ufs/sjoerd/#tmp"
gets translated into "/ufs/sjoerd/#tmp" which, when interpreted as a
URL is file "/ufs/sjoerd/" with fragment ID "tmp".
Here's an easy fix. (An alternative fix would be to change the
various implementations of pathname2url and url2pathname to include
calls to quote and unquote.
[The main problem is with the normal use of URLs:
url = url2pathname(file)
transmit url
url, tag = splittag(url)
urlopen(url)
]
In addition, this patch fixes some uses of unquote:
- the host part of URLs should be unquoted
- the file path in the FTP URL should be unquoted before it is split
into components.
- because of the latter, I removed all unquoting from ftpwrapper,
and moved it to the caller, but that is not essential
when we create a recursive instance, by setting the class variable
'FieldStorageClass' to the desired class. By default, this is set to
None, in which case we use self.__class__ (as before).
When literal mode is entered it should exit automatically when the
matching close tag of the last unclosed open tag is encountered. This
patch fixes this.
In SimpleHTTPServer.py, the server specified in test() should
be BaseHTTPServer.HTTPServer, in case the request handler should
want to reference the two attributes added by
BaseHTTPServer.server_bind:
self.server_name = hostname
self.server_port = port
There was some Bobo CGI code that wanted access to those attributes.
In CGIHTTPServer.py, the list of acceptable formats is -split-
on spaces but -joined- on commas, resulting in double commas
in the joined text. It appears harmless to my browser but
ought to be fixed anyway.

Since we were making a copy of the longopts list anyway, we now use
the list() function -- this made it necessary to change all uses of
the local variable (and argument) 'list' to something more meaningful,

Also added docstrings (copied from the library manual) and removed the
(now redundant) module comments.
filenames generated are easily predictable, it is possible to trick an
unsuspecting program into overwriting another file by creating a
symbolic link with the predicted name. Fix this by using the
low-level os.open() function with the O_EXCL flag and mode 0700. On
non-Unix platforms, presumably there are no symbolic links so the
problem doesn't exist. The explicit test for Unix (posix, actually)
makes it possible to change the non-Unix logic to work without a
try-except clause.

pdb.py Uses the Breakpoint class so one can enable/disable breakpoints,
set temporary ones, set ignore counts, and conditions. The last
can be set using the 'b' command
b 243 , i>4 ( b 243,i>4 if you are space adverse)
or with the condition command so conditions can be changed
for a particular breakpoint.
Breakpoints are numbered from 1 on, and if a breakpoint is deleted,
the number is not reused. All the breakpoint handling commands
refer to breakpoints by number. To be consistent, the clear command
does so as well, which is the one change from the original pdb that
is not transparent. Thus only the breakpoint command 'b' uses a
line number or file:line or method. You can also give
b whrandom.random and the method will be searched for along
sys.path. This is implemented with an 'egrep' command and so
is not as portable as it might be. [ see lineinfo() and
lineinfoCmd ]
Breakpoints cannot be set at a line that is blank or a '#' comment
or starts a triply quoted comment. This is because I would like
this behavior in my DDD interface and think it reasonable for
pdb as well. It can be removed readily, however as it is all
incorporated in the routine checkline(). If one attempts to
set a breakpoint at a 'def' line, the breakpoint is automatically
moved to the first executable line after the 'def'. This too is
in checkline().
do_EOF() returns zero so typing an end-of-file character as a command
does nothing. 'quit' does the quitting.
The routine defaultFile() is present so as to preserve the current
pdb behavior and yet allow me to override it in pydb.
There's some code in lineinfo() that is probably mainly useful only
for pydb and if you prefer, much up to the comment "Best first guess"
could be removed.
Keith Davidson provided the code for handling $HOME/.pdbrc and
./.pdbrc, and it has been incorporated. He also provided the
alias handling routine. I modified it a bit so it could live
nicely in precmd(). He and I have been in contact; he has the
new pdb (and pydb) with his code incorporated. He also asked
about the possibility of allowing multiple commands on one
line, such as step;step or s;s or with an alias such as
alias ct tbreak %1 ; continue
and since it was so easy, that's in place as well. It's a simple
'split the line at the first ";"' operation and puts the second
half in the command queue (self.cmdqueue). This has the unfortunate
effect of destroying a line like print "i: "+i+"; j: "+j
but either there's a simple way to deal with this, or my attitude
will remain that pdb is a debugger, not a compiler/parser/etc.
An alias like alias 4s s;;s;
will work because the adjacent and trailing ";" act like a <cr> which
repeats the last command. Of course, either s;s;s;s or s;;; would be
a bit more sensible.
The help commands have been updated.
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.

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.

problem that randint() was accidentally defined as taking an inclusive

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

- 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

Also:

- 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'))

arbitrary scripts in restricted mode, and it will do the right thing.

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.
