outer level, the iterator protocol is used for memory-efficiency (the
outer sequence may be very large if fully materialized); at the inner
level, PySequence_Fast() is used for time-efficiency (these should
always be sequences of length 2).
dictobject.c, new functions PyDict_{Merge,Update}FromSeq2. These are
wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2-
sequences argument instead of a mapping object. For now, I left these
functions file static, so no corresponding doc changes. It's tempting
to change dict.update() to allow a sequence-of-2-seqs argument too.
Also changed the name of dictionary's keyword argument from "mapping"
to "x". Got a better name? "mapping_or_sequence_of_pairs" isn't
attractive, although more so than "mosop" <wink>.
abstract.h, abstract.tex: Added new PySequence_Fast_GET_SIZE function,
much faster than going thru the all-purpose PySequence_Size.
libfuncs.tex:
- Document dictionary().
- Fiddle tuple() and list() to admit that their argument is optional.
- The long-winded repetitions of "a sequence, a container that supports
iteration, or an iterator object" is getting to be a PITA. Many
months ago I suggested factoring this out into "iterable object",
where the definition of that could include being explicit about
generators too (as is, I'm not sure a reader outside of PythonLabs
could guess that "an iterator object" includes a generator call).
- Please check my curly braces -- I'm going blind <0.9 wink>.
abstract.c, PySequence_Tuple(): When PyObject_GetIter() fails, leave
its error msg alone now (the msg it produces has improved since
PySequence_Tuple was generalized to accept iterable objects, and
PySequence_Tuple was also stomping on the msg in cases it shouldn't
have even before PyObject_GetIter grew a better msg).
When describing a Boolean return value, use "true" and "false" instead of
"1" and "0".
Style-guide conformance: no "iff" -- to obscure for many readers. ;-(
non-standard but common types. Including Martin's suggestion to add
rejected non-standard types from patch #438790. Specifically,
guess_type(), guess_extension(): Both the functions and the methods
grow an optional "strict" flag, defaulting to true, which determines
whether to recognize non-standard, but commonly found types or not.
Also, I sorted, reformatted, and culled duplicates from the big
types_map dictionary. Note that there are a few non-equivalent
duplicates (e.g. .cdf and .xls) for which the first will just get
thrown away. I didn't remove those though.
Finally, use of the module as a script as grown the -l and -e options
to toggle strictness and to do guess_extension(), respectively.
Doc and unittest updates too.
parameters, given a hyperlink to the right part of the documentation to
make it easier to look those up. Also, refer to the file() function/
constructor instead of open() now that that is where the actual docs for
those parameters live.
This closes SF bug #472004.
This was submitted by Moshe, but apparently he's too busy to check it
in himself. He wrote:
Here is a function in GNU readline called add_history,
which is used to manage the history list. Though Python
uses this function internally, it does not expose it to
the Python programmer. This patch adds direct interface
to this function with documentation.
This could be used by friendly modules to "seed" the
history with commands.
This changes Pythread_start_thread() to return the thread ID, or -1
for an error. (It's technically an incompatible API change, but I
doubt anyone calls it.)
Mostly by Toby Dickenson and Titus Brown.
Add an optional argument to a decompression object's decompress()
method. The argument specifies the maximum length of the return
value. If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute. (Not to be confused with
unused_data, which is a separate issue.)
Difference from SF patch: Default value for unconsumed_tail is ""
rather than None. It's simpler if the attribute is always a string.

Rewrote the calibration docs.
Modern boxes are so friggin' fast, and a profiler event does so much work
anyway, that the cost of looking up an instance vrbl (the bias constant)
per profile event just isn't a big deal.
functions to include information about how they affect the operation of
those functions when used as the "mode" parameter.

Added warnings to the os.tempnam() and os.tmpnam() functions regarding their
security problem. These warning mirror the warnings added to the runtime
by Skip Montanaro.

Fred, is this a right way to fix it? If not, the earlier place in the
same paragraph that does render as
foo$
is also wrong.

the warning text and the HTML version does not create images of the warning
text.
the object has been pickled; don't mutate the instance dict in the
__getstate__() method. Other minor changes for style. Broke up the
displayed interactive session to get better page-breaking behavior for
typeset versions, and to point out an important aspect of the example.
This closes SF bug #453914.
easy for 2.2 new-style classes, but trickier for classic classes, and
different approaches are needed "depending". The function will allow
later code to treat all flavors of classes uniformly.
Once upon a time, I put together a little function
that tries to find the canonical filename for a given
pathname on POSIX. I've finally gotten around to
turning it into a proper patch with documentation.
On non-POSIX, I made it an alias for 'abspath', as
that's the behavior on POSIX when no symlinks are
encountered in the path.
Example:
>>> os.path.realpath('/usr/bin/X11/X')
'/usr/X11R6/bin/X'
This patch adds the features from RFC 2487 (Secure SMTP
over TLS) to the smtplib module:
- A starttls() function
- Wrapper classes that simulate enough of sockets and
files for smtplib, but really wrap a SSLObject
- reset the list of known SMTP extensions at each call
of ehlo(). This should have been the case anyway.
added all the telnet options known to arpa/telnet.h
added all the options registered with IANA as of today
added the possibility for the user to have it's own option negotiation callback
right thing with page breaks in long examples, while the verbatim
environment does not. This causes the example to wrap to the next page
instead of overwriting the page footer and bottom margin.
__dict__ attribute. Deleting it, or setting it to a non-dictionary
result in a TypeError. Note that getting it the first time magically
initializes it to an empty dict so that func.__dict__ will always
appear to be a dictionary (never None).

Fixed description of RE modifiers so that RE{#} and RE{#,} are more

Minor local consistency adjustments.
A couple of small tweaks to the setdlopenflags() description.
For setprofile() and settrace(), convert some references to become
hyperlinks in the HTML version.
- This module, despite its name, now should conform to RFC 2822, the
update to RFC 822.
- This module doesn't just represent "email headers", but entire email
messages.
- Added documentation for other useful public functions such as
quote(), unquote(), praseaddr(), and dump_address_pair().

VPython folks were particularly problematic for their students. (The
other one was integer division...) This implements (my) SF patch

externally visible things.
Fred and Fredrik, do your stuff! You both need to proof this.

Add an index entry for the Telnet protocol.
Always refer to the protocol as Telnet instead of telnet.
committed.
tokenize.py: I like these changes, and have tested them extensively
without even realizing it, so I just updated the docstring and the docs.
tabnanny.py: Also liked this, but did a little code fiddling. I should
really rewrite this to *exploit* generators, but that's near the bottom
of my effort/benefit scale so doubt I'll get to it anytime soon (it
would be most useful as a non-trivial example of ideal use of generators;
but test_generators.py has already grown plenty of food-for-thought
examples).
inspect.py: I'm sure Ping intended for this to continue running even
under 1.5.2, so I reverted this to the last pre-gen-branch version. The
"bugfix" I checked in in-between was actually repairing a bug *introduced*
by the conversion to generators, so it's OK that the reverted version
doesn't reflect that checkin.
