mutable! We do not want to shock anyone.
This closes SF bug #483805.
Re-factor so that the description of the "access" keyword parameter is not
repeated in both the descriptions of mmap(). Also, only make sure the first
description of mmap() appears in the index. The the index link is followed,
the first is now used to locate the page on the screen; chances are really good
both will be visible. This avoids the problem that the index entry for the
second is selected and the first version is not visible, making the reader
consider that mmap() is not available on Windows.
parameters (like \UNIX) are commonly entered using an empty group to
separate the markup from a following inter-word space; this is not
needed when the next character is punctuation, or the markup is the
last thing in the enclosing group. These cases were marked
inconsistently; the empty group is now *only* used when needed.
- the attrs value may be re-used by the parser, so the implementation
cannot rely on owning the object.
- an element with no namespace encountered in namespace mode will have a URI
of None, not "" (startElementNS() only).
Fixed a couple of minor markup issues as well.
documentation. This addresses previously undocumented parts of the
public interfaces, the differences between pickle and cPickle,
security concerns, and on and on.
Fred please proofread!
This gives mmap() on Windows the ability to create read-only, write-
through and copy-on-write mmaps. A new keyword argument is introduced
because the mmap() signatures diverged between Windows and Unix, so
while they (now) both support this functionality, there wasn't a way to
spell it in a common way without introducing a new spelling gimmick.
The old spellings are still accepted, so there isn't a backward-
compatibility issue here.
and NEWS. Bugfix candidate? That's a dilemma for Anthony <wink>: /F
did fix a longstanding bug here, but the fix can cause code to raise an
exception that previously worked by accident.
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.
