clear from recent discussions on c.l.py that people are a bit confused about
the differences between the old bsddb, the new bssdb, the bsddb3/PyBSDDB
package and changes to file formats. Tried to clarify the issues.
out a month's worth of checkins to libstdtypes.tex (including my
extended slice docs).
I think this checkin merges them all back in, but if you make one of
these checkins:
revision 1.97
date: 2002/06/14 00:27:13; author: nnorwitz
Use \code{True} (or False) instead of true/false.
Not sure if code is correct, but that is what's in this file.
I've seen \constant{True} in other places.
----------------------------
revision 1.95
date: 2002/05/22 20:39:43; author: bwarsaw
Jack's documentation for the U mode character on the file()
constructor, vetted by Barry.
----------------------------
revision 1.94
date: 2002/05/21 18:19:15; author: rhettinger
Patch 543387. Document deprecation of complex %, //,and divmod().
----------------------------
revision 1.93
date: 2002/05/15 15:45:25; author: rhettinger
Added missing index entries for mapping methods. Closes patch
#548693.
some checking may be in order.
checking them in? Oh well, this fixes various obvious mistakes and
changes a subsubsubsection (which doesn't exist) into a subsubsection
(which does). I'm not sure this matches the intent, but it seems to
read OK on a quick skim.
- Implement the behavior as specified in PEP 277, meaning os.listdir()
will only return unicode strings if it is _called_ with a unicode
argument.
- And then return only unicode, don't attempt to convert to ASCII.
- Don't switch on Py_FileSystemDefaultEncoding, but simply use the
default encoding if Py_FileSystemDefaultEncoding is NULL. This means
os.listdir() can now raise UnicodeDecodeError if the default encoding
can't represent the directory entry. (This seems better than silcencing
the error and fall back to a byte string.)
- Attempted to decribe the above in Doc/lib/libos.tex.
- Reworded the Misc/NEWS items to reflect the current situation.
This checkin also fixes bug #696261, which was due to os.listdir() not
using Py_FileSystemDefaultEncoding, like all file system calls are
supposed to.
[ 555817 ] Flawed fcntl.ioctl implementation.
with my patch that allows for an array to be mutated when passed
as the buffer argument to ioctl() (details complicated by
backwards compatibility considerations -- read the docs!).
rarely needed, but can sometimes be useful to release objects
referenced by the traceback held in sys.exc_info()[2]. (SF patch
#693195.) Thanks to Kevin Jacobs!
* Modules/bz2module.c
(BZ2FileObject): Now the structure includes a pointer to a file object,
instead of "inheriting" one. Also, some members were copied from the
PyFileObject structure to avoid dealing with the internals of that
structure from outside fileobject.c.
(Util_GetLine,Util_DropReadAhead,Util_ReadAhead,Util_ReadAheadGetLineSkip,
BZ2File_write,BZ2File_writelines,BZ2File_init,BZ2File_dealloc,
BZ2Comp_dealloc,BZ2Decomp_dealloc):
These functions were adapted to the change above.
(BZ2File_seek,BZ2File_close): Use PyObject_CallMethod instead of
getting the function attribute locally.
(BZ2File_notsup): Removed, since it's not necessary anymore to overload
truncate(), and readinto() with dummy functions.
(BZ2File_methods): Added xreadlines() as an alias to BZ2File_getiter,
and removed truncate() and readinto().
(BZ2File_get_newlines,BZ2File_get_closed,BZ2File_get_mode,BZ2File_get_name,
BZ2File_getset):
Implemented getters for "newlines", "mode", and "name".
(BZ2File_members): Implemented "softspace" member.
(BZ2File_init): Reworked to create a file instance instead of initializing
itself as a file subclass. Also, pass "name" object untouched to the
file constructor, and use PyObject_CallFunction instead of building the
argument tuple locally.
(BZ2File_Type): Set tp_new to PyType_GenericNew, tp_members to
BZ2File_members, and tp_getset to BZ2File_getset.
(initbz2): Do not set BZ2File_Type.tp_base nor BZ2File_Type.tp_new.
* Doc/lib/libbz2.tex
Do not mention that BZ2File inherits from the file type.
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.
Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().
Sets.py:
* Replace old ifilter() usage with new.
__ne__ no longer complain if they don't know how to compare to the other
thing. If no meaningful way to compare is known, saying "not equal" is
sensible. This allows things like
if adatetime in some_sequence:
and
somedict[adatetime] = whatever
to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.
It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().
* Fixed typo in exception message for times()
* Filled in missing times_traverse()
* Document reasons that imap() did not adopt a None fill-in feature
* Document that count(sys.maxint) will wrap-around on overflow
* Add overflow test to islice()
* Check that starmap()'s argument returns a tuple
* Verify that imap()'s tuple re-use is safe
* Make a similar tuple re-use (with safety check) for izip()
This patch adds stdin, stdout as optional arguments to the cmd.Cmd
constructor (defaulting to sys.stdin, sys.stdout), and changes the Cmd
methods throughout to use self.stdout.write() and self.stdin.foo for
output and input. This allows much greater flexibility for using cmd -
for instance, hooking it into a telnet server.
Patch for library module and for documentation.
