Skip Montanaro b4a0417e91 new CSV file processing module - see PEP 305 2003-03-20 23:29:12 +00:00
Tim Peters 9905b943f7 New private API functions _PyFloat_{Pack,Unpack}(4,8}. This is a
refactoring to get all the duplicates of this delicate code out of the
cPickle and struct modules.
2003-03-20 20:53:32 +00:00
Tim Peters d50ade68ec SF bug 705836: struct.pack of floats in non-native endian order
pack_float, pack_double, save_float:  All the routines for creating
IEEE-format packed representations of floats and doubles simply ignored
that rounding can (in rare cases) propagate out of a long string of
1 bits.  At worst, the end-off carry can (by mistake) interfere with
the exponent value, and then unpacking yields a result wrong by a factor
of 2.  In less severe cases, it can end up losing more low-order bits
than intended, or fail to catch overflow *caused* by rounding.

Bugfix candidate, but I already backported this to 2.2.

In 2.3, this code remains in severe need of refactoring.

Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter
to more accurately describe what the function does.

Suggested by Thomas Wouters.
2003-03-17 19:46:11 +00:00
Jack Jansen 7b59b42a38 Added a define EXTRAMACHDEPPATH which can be used to add sys.path items
for specific platforms. Use this to add plat-mac and
plat-mac/lib-scriptpackages on MacOSX. Also tested for not having adverse
effects on Linux, and I think this code isn't used on Windows anyway.

Fixes #661521.

Thomas Wouters 9e1c192525 binascii_a2b_base64: Properly return an empty string if the input was all
invalid, rather than returning a string of random garbage of the
    estimated result length. Closes SF patch #703471 by Hye-Shik Chang.

Will backport to 2.2-maint (consider it done.)

Greg Ward 5c49ef2116 Open with O_NONBLOCK to avoid hanging on open(). 2003-03-11 16:53:13 +00:00
Greg Ward 0b6dfb808c <sys/soundcard.h> seems to exist on both Linux and FreeBSD, so include
it instead of the OS-specific <linux/soundcard.h> or <machine/soundcard.h>.

Mixers devices have an ioctl-only interface, no read/write -- so the
flags passed to open() don't really matter.  Thus, drop the 'mode'
parameter to openmixer() (ie. second arg to newossmixerobject()) and
always open mixers with O_RDWR.

Just van Rossum 2ac79ef9e3 removing one Mac hack and add another:
- The applet logic has been replaced to bundlebuilder's bootstrap script
- Due to Apple being extremely string about argv[0], we need a way to
  specify the actual executable name for use with sys.executable. See
  the comment embedded in the code.

Just van Rossum 2fe07fda2d plugged leak noted by nnorwitz: the 'et' format returns allocated memory 2003-03-03 19:07:13 +00:00
Just van Rossum 96b1c903f5 Patch #683592 revisited, after discussions with MvL:
- 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.

Py_FileSystemDefaultEncoding.

Walter Dörwald dd8766a65b Change the test encoding from "ISO8859-1" to "ISO-8859-1"
(see SF bug #690309) and raise ImportErrors instead of
RuntimeErrors, so building Python continues even
if importing iconv_codecs fails.

This is a temporary fix until we get proper configure
support for "broken" iconv implementations.

Raymond Hettinger 61fe64d5de User requested changes to the itertools module.
Subsumed times() into repeat().
Added cycle() and chain().
2003-02-23 04:40:07 +00:00
Walter Dörwald e9b851a5e9 Use 'ISO8859-1' instead of 'ASCII' when testing whether byteswapping
is required for the chosen internal encoding in the init function,
as this seems to have a better chance of working under Irix and
Solaris.

Also change the test character from '\x01' to '0'.

This might fix SF bug #690309.

Guido van Rossum b76bdf8ef7 The connect timeout code wasn't working on Windows.
Rather than trying to second-guess the various error returns
of a second connect(), use select() to determine whether the
socket becomes writable (which means connected).

Tim Peters b9ce7cd8b8 save_global(): Trying to resolve module.name can fail for two
reasons:  importing module can fail, or the attribute lookup
module.name can fail.  We were giving the same error msg for
both cases, making it needlessly hard to guess what went wrong.
These cases give different error msgs now.
2003-02-18 20:50:45 +00:00

Neal Norwitz 0c0aad948a Fix 64-bit problem, ParseTuple("i") needs C ints; ("l") needs C longs.
Use "l" as that *probably* makes more sense (at least to me it does :-)
And the test passes on the alpha.
2003-02-18 03:37:49 +00:00
Neal Norwitz e241ce830a Added test_posix (hopefully it works on Windows).
Remove PyArg_ParseTuple() for methods which take no args,
use METH_NOARGS instead
2003-02-17 18:17:05 +00:00
Neal Norwitz 5c1ba53f8c Use correct function name to PyArg_ParseTuple("is_package").
Fix off-by-1 error in normalize_line_endings():
  when *p == '\0' the NUL was copied into q and q was auto-incremented,
  the loop was broken out of,
  then a newline was appended followed by a NUL.
  So the function, in effect, was strcpy() but added two extra chars
  which was caught by obmalloc in debug mode, since there was only
  room for 1 additional newline.

Get test working under regrtest (added test_main).

Tim Peters 080c88b912 cPickle.c, load_build(): Taught cPickle how to pick apart
the optional proto 2 slot state.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

pickletester.py, test_pickle.py:  Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

dictobject.c, PyDict_Next():  documented intended use.
2003-02-15 03:01:11 +00:00
Tim Peters 71fcda5ba7 cPickle produces NEWOBJ appropriately now. It still doesn't know

Tim Peters aae53d47d6 The version of PyImport_Import() in cPickle is no longer needed (an edited

Guido van Rossum 729765079e Another dummy type.
Curious: Str didn't need me to put something in tp_new, but Null did.
Why the difference?
2003-02-13 18:44:57 +00:00
Tim Peters eab7db3cee Taught cPickle how to read pickles containing NEWOBJ. This won't get
exercised by the test suite before cPickle knows how to create NEWOBJ
too.  For now, it was just tried once by hand (via loading a NEWOBJ
pickle created by pickle.py).
2003-02-13 18:24:14 +00:00

Neal Norwitz 10b214c2fd Use configure to check for inet_aton. 2003-02-13 02:11:10 +00:00
Guido van Rossum ad05cdfa1f Addressing SF bug #643005, implement socket.inet_aton() using
inet_aton() rather than inet_addr() -- the latter is obsolete because
it has a problem: "255.255.255.255" is a valid address but
indistinguishable from an error.

(I'm not sure if inet_aton() exists everywhere -- in case it doesn't,
I've left the old code in with an #ifdef.)
2003-02-12 23:08:22 +00:00

Tim Peters 42f08ac1e3 Implemented batching for dicts in cPickle. This is after two failed

it was a godawful mess to read.

Gustavo Niemeyer a33d0aa693 Unparenting BZ2File, as discussed in SF patch #661796.
* 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.

Tim Peters aa7d849c7a timedelta comparison and datetime addition: as the Python implementation
of datetime does, accept instances of subclasses too.
2003-02-08 03:28:59 +00:00
Tim Peters 07534a607b Comparison for timedelta, time, date and datetime objects: __eq__ and
__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().

Tim Peters 3e667d5452 cPickle: exempt two_tuple from GC -- it's a speed hack, and doesn't
guarantee to keep valid pointers in its slots.

tests:  Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places.  Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.

Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.

Guido van Rossum d4b920c8bd Rename the extension registry variables to have leading underscores --

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.

Tim Peters 5b7da39f23 Brought some module variables into synch with pickle.py's current values.
Imported the extension-registry dicts from copy_reg.py, in preparation for
tackling EXT[124].
2003-02-04 00:21:07 +00:00
Tim Peters 0c7c48e02c load_counted_long(): Changed a ValueError to an UnpicklingError, just
because it seems more consistent with the rest of the code.

cPickle_PyMapping_HasKey():  This extern function isn't used anywhere in
Python or Zope, so got rid of it.
2003-02-03 22:07:24 +00:00
Guido van Rossum 7d9ea5013f - Thanks to Scott David Daniels, a subtle bug in how the zlib
extension implemented flush() was fixed.  Scott also rewrite the
  zlib test suite using the unittest module.  (SF bug #640230 and
  patch #678531.)

Backport candidate I think.
2003-02-03 20:45:52 +00:00
Tim Peters e0a3907904 PDATA_PUSH and PDATA_APPEND. documented, and reformatted for better

load_bool():  Now that I know the intended difference between _PUSH and
_APPEND, used the right one.

Pdata_grow():  Squashed out a redundant overflow test.

Tim Peters 1d63c9f151 cPickle support for TUPLE[123]. Incidentally plugged several undetected
overflow holes in Pdata_grow().
2003-02-02 20:29:39 +00:00
Tim Peters 0bc93f5c8b Massive edits. If p is a pointer to a struct, and p->f is a pointer to
a function, then

    p->f(arg1, arg2, ...)

is semantically the same as

    (*p->f)(arg1, arg2, ...)

Changed all instances of the latter into the former.  Given how often
the code embeds this kind of expression in an if test, the unnecessary
parens and dereferening operator were a real drag on readability.
2003-02-02 18:29:33 +00:00
Tim Peters ac5687a515 Minor cleanup, mostly adding horizontal whitespace, and breaking apart
embedded assignments, for readability.

Tim Peters 70b02d79f9 Beefed up the tests by putting in more "for proto in protocols:" outer
loops.  Renamed DATA and BINDATA to DATA0 and DATA1.  Included
disassemblies, but noted why we can't test them.  Added XXX comment to
cPickle about a mysterious comment, where pickle and cPickle diverge
in how they number PUT indices.

2003-02-02 16:14:23 +00:00
Tim Peters 4190fb8429 Add cPickle support for PROTO. Duplicated PROTO/LONG1/LONG4 code in
the hitherto unknown (to me) noload() cPickle function, which is (a)
something we don't test at all, and (b) pickle.py doesn't have.

Fred Drake 06dd8cf5e4 Fix memory leak: free memory storing the content model passed to the
ElementDeclHandler by Expat.

2003-02-02 03:54:17 +00:00
Tim Peters ee1a53cbb1 cPickle.c: Full support for the new LONG1 and LONG4. Added comments.
Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's
no need to do things like multiply by sizeof(char) in hairy malloc
arguments.  Fixed an undetected-overflow bug in readline_file().

longobject.c:  Fixed a really stupid bug in the new _PyLong_NumBits.

pickle.py:  Fixed stupid bug in save_long():  When proto is 2, it
wrote LONG1 or LONG4, but forgot to return then -- it went on to
append the proto 1 LONG opcode too.
Fixed equally stupid cancelling bugs in load_long1() and
load_long4():  they *returned* the unpickled long instead of pushing
it on the stack.  The return values were ignored.  Tests passed
before only because save_long() pickled the long twice.

Fixed bugs in encode_long().

Noted that decode_long() is quadratic-time despite our hopes,
because long(string, 16) is still quadratic-time in len(string).
It's hex() that's linear-time.  I don't know a way to make decode_long()
linear-time in Python, short of maybe transforming the 256's-complement
bytes into marshal's funky internal format, and letting marshal decode
that.  It would be more valuable to make long(string, 16) linear time.

pickletester.py:  Added a global "protocols" vector so tests can try
all the protocols in a sane way.  Changed test_ints() and test_unicode()
to do so.  Added a new test_long(), but the tail end of it is disabled
because it "takes forever" under pickle.py (but runs very quickly under
cPickle:  cPickle proto 2 for longs is linear-time).
2003-02-02 02:57:53 +00:00
Tim Peters 5bd2a79b22 The C pickle now knows how to deal with a proto= argument. Assorted
code cleanups, and purged more references to text-vs-binary modes.

Tim Peters cba30e2c96 Trimmed trailing whitespace. 2003-02-01 06:24:36 +00:00
Tim Peters 797ec24e87 Added #defines for proto 2 opcodes; gave the Pickler a proto member;
removed woefully inadequate opcode docs and pointed to pickletools.py
instead.
2003-02-01 06:22:36 +00:00
Tim Peters 70533e28ad New functions alloc_{time,datetime}. Got rid of all setstate-like
functions.  Reworked {time,datetime}_new() to do what their corresponding
setstates used to do in their state-tuple-input paths, but directly,
without constructing an object with throwaway state first.  Tightened
the "is this a state tuple input?" paths to check the presumed state
string-length too, and to raise an exception if the optional second state
element isn't a tzinfo instance (IOW, check these paths for type errors
as carefully as the normal paths).
2003-02-01 04:40:04 +00:00
Tim Peters b57f8f02ba There's no good reason for datetime objects to expose __getstate__()
anymore either, so don't.  This also allows to get rid of obscure code
making __getnewargs__ identical to __getstate__ (hmm ... hope there
wasn't more to this than I realize!).
2003-02-01 02:54:15 +00:00
Tim Peters 1f1b2d2e68 Removed all uses of the out-of-favor __safe_for_unpickling__ magic
attr, and copy_reg.safe_constructors.

Raymond Hettinger 96ef8115dd Move itertools module from the sandbox and into production. 2003-02-01 00:10:11 +00:00
Tim Peters 506be287aa The various datetime object __setstate__() methods are no longer public
(pickling no longer needs them, and immutable objects shouldn't have
visible __setstate__() methods regardless).  Rearranged the code to
put the internal setstate functions in the constructor sections.
Repaired the timedelta reduce() method, which was still producing
stuff that required a public timedelta.__setstate__() when unpickling.
2003-01-31 22:27:17 +00:00
Guido van Rossum 8e0ad0cb0b Ignore the state returned by __reduce__ if it is Py_None. 2003-01-31 21:10:31 +00:00

Guido van Rossum 4f707ac8b1 SF patch 676472 by Geoff Talvola, reviewed by Ben Laurie.
Geoff writes:
  This is yet another patch to _ssl.c that sets the
  underlying BIO to non-blocking if the socket being

  This seems to fix bug #673797 which was not fixed by my
  previous patch.
2003-01-31 18:13:18 +00:00
Walter Dörwald 2e0b18af30 Change the treatment of positions returned by PEP293
error handers in the Unicode codecs: Negative
positions are treated as being relative to the end of
the input and out of bounds positions result in an
IndexError.

Also update the PEP and include an explanation of
this in the documentation for codecs.register_error.

Fixes a small bug in iconv_codecs: if the position
from the callback is negative *add* it to the size
instead of substracting it.

From SF patch #677429.

2003-01-31 16:26:50 +00:00
Tim Peters 5b8132ffa3 _PyLong_NumBits(): The definition of this was too specific to the quirky
needs of pickling longs.  Backed off to a definition that's much easier
to understand.  The pickler will have to work a little harder, but other
uses are more likely to be correct <0.5 wink>.

_PyLong_Sign():  New teensy function to characterize a long, as to <0, ==0,
or >0.

2003-01-31 01:37:35 +00:00
Guido van Rossum 177e41a117 Change the approach to pickling to use __reduce__ everywhere. Most
classes have a __reduce__ that returns (self.__class__,
self.__getstate__()).  tzinfo.__reduce__() is a bit smarter, calling
__getinitargs__ and __getstate__ if they exist, and falling back to
__dict__ if it exists and isn't empty.
2003-01-30 22:06:23 +00:00
Walter Dörwald b4ff1113ca Check whether the choosen encoding requires byte swapping
for this iconv() implementation in the init function.

For encoding: use a byteswapped version of the input if
neccessary.

For decoding: byteswap every piece returned by iconv()
if neccessary (but not those pieces returned from the
callback)

Comment out test_sane() in the test script, because
whether this works depends on whether byte swapping
is neccessary or not (an on Py_UNICODE_SIZE)

Tim Peters baefd9e552 Added new private API function _PyLong_NumBits. This will be used at the
start for the C implemention of new pickle LONG1 and LONG4 opcodes (the

the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).

Tim Peters 8d81a012ef date and datetime comparison: when we don't know how to
compare against "the other" argument, we raise TypeError,
in order to prevent comparison from falling back to the
default (and worse than useless, in this case) comparison
by object address.

That's fine so far as it goes, but leaves no way for
another date/datetime object to make itself comparable
to our objects.  For example, it leaves Marc-Andre no way
to teach mxDateTime dates how to compare against Python
dates.

Discussion on Python-Dev raised a number of impractical
ideas, and the simple one implemented here:  when we don't
know how to compare against "the other" argument, we raise
TypeError *unless* the other object has a timetuple attr.
In that case, we return NotImplemented instead, and Python
will give the other object a shot at handling the
comparison then.

Note that comparisons of time and timedelta objects still
suffer the original problem, though.

Tim Peters 2a44a8d332 SF bug 660872: datetimetz constructors behave counterintuitively (2.3a1).
This gives much the same treatment to datetime.fromtimestamp(stamp, tz) as

thing with the tz argument instead of a senseless thing.

Tim Peters b1049e8eca fromutc(): Repair incorrect failure return, as noted by NealN. Thanks! 2003-01-23 17:20:36 +00:00
Tim Peters 52dcce24e2 Bringing the code and test suite into line with doc and NEWS changes
checked in two days agao:

Refactoring of, and new rules for, dt.astimezone(tz).

dt must be aware now, and tz.utcoffset() and tz.dst() must not return None.
The old dt.astimezone(None) no longer works to change an aware datetime
into a naive datetime; use dt.replace(tzinfo=None) instead.

The tzinfo base class now supplies a new fromutc(self, dt) method, and
datetime.astimezone(tz) invokes tz.fromutc().  The default implementation
of fromutc() reproduces the same results as the old astimezone()
implementation, but tzinfo subclasses can override fromutc() if the
default implementation isn't strong enough to get the correct results
in all cases (for example, this may be necessary if a tzinfo subclass
models a time zone whose "standard offset" (wrt UTC) changed in some
year(s), or in some variations of double-daylight time -- the creativity
of time zone politics can't be captured in a single default implementation).

61: Added support for namespace prefixes, which can be enabled by setting the
    "namespace_prefixes" attribute on the parser object.
65: Disable profiling changes for Python 2.0 and 2.1.
66: Update pyexpat to export the Expat 1.95.5 XML_GetFeatureList()
    information, and tighten up a type declaration now that Expat is using
    an incomplete type rather than a void * for the XML_Parser type.
67: Clarified a comment.
    Added support for XML_UseForeignDTD(), new in Expat 1.95.5.
68: Refactor to avoid partial duplication of the code to construct an
    ExpatError instance, and actually conform to the API for the exception
    instance as well.
69: Remove some spurious trailing whitespace.
    Add a special external-entity-ref handler that gets installed once a
    handler has raised a Python exception; this can cancel actual parsing
    earlier if there's an external entity reference in the input data
    after the the Python excpetion has been raised.
70: Untabify APPEND.
71: Backport PyMODINIT_FUNC for 2.2 and earlier.
2003-01-21 10:58:18 +00:00
Tim Peters 327098a613 New rule for tzinfo subclasses handling both standard and daylight time:
When daylight time ends, an hour repeats on the local clock (for example,
in US Eastern, the clock jumps from 1:59 back to 1:00 again).  Times in
the repeated hour are ambiguous.  A tzinfo subclass that wants to play
with astimezone() needs to treat times in the repeated hour as being
standard time.  astimezone() previously required that such times be
treated as daylight time.  There seems no killer argument either way,
but Guido wants the standard-time version, and it does seem easier the
new way to code both American (local-time based) and European (UTC-based)
switch rules, and the astimezone() implementation is simpler.

hoped it would be, but not too bad.  A test had to change:

doesn't exist in that case.

Tim Peters 0bf60bd67f Utterly minimal changes to collapse datetimetz into datetime, and timetz
into time.  This is little more than *exporting* the datetimetz object
under the name "datetime", and similarly for timetz.  A good implementation
of this change requires more work, but this is fully functional if you
don't stare too hard at the internals (e.g., right now a type named
"datetime" shows up as a base class of the type named "datetime").  The
docs also need extensive revision, not part of this checkin.

The attached patch enables shared extension
modules to build cleanly under Cygwin without

DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Tim Peters adf642038e A new implementation of astimezone() that does what we agreed on in all

Just van Rossum 9a3129c148 Fix for bug #661136
Lesson learned: kids should not be allowed to use API's starting
with an underscore :-/
zipimport in 2.3a1 is even more broken than I thought: I attemped
to _PyString_Resize a string created by PyString_FromStringAndSize,
which fails for strings with length 0 or 1 since the latter returns
an interned string in those cases. This would cause a SystemError
with empty source files (and no matching pyc) in the zip archive.
I rewrote the offending code to simply allocate a new buffer and
avoid _PyString_Resize altogether.
Added a test that would've caught the problem.

Tim Peters 397301eccb The tzinfo methods utcoffset() and dst() must return a timedelta object
(or None) now.  In 2.3a1 they could also return an int or long, but that
was an unhelpfully redundant leftover from an earlier version wherein
they couldn't return a timedelta.  TOOWTDI.

Tim Peters 710fb1548a astimezone() internals: if utcoffset() returns a duration, complain if

Tim Peters c5dc4da125 The astimezone() correctness proof endured much pain to prove what
turned out to be 3 special cases of a single more-general result.
Proving the latter instead is a real simplification.
2003-01-02 17:55:03 +00:00
Tim Peters 5d644dd25a SF bug 661086: datetime.today() truncates microseconds.
On Windows, it was very common to get microsecond values (out of
.today() and .now()) of the form 480999, i.e. with three trailing
nines.  The platform precision is .001 seconds, and fp rounding
errors account for the rest.  Under the covers, that 480999 started
life as the fractional part of a timestamp, like .4809999978.
Rounding that times 1e6 cures the irritation.

Confession:  the platform precision isn't really .001 seconds.  It's
usually worse.  What actually happens is that MS rounds a cruder value
to a multiple of .001, and that suffers its own rounding errors.

A tiny bit of refactoring added a new internal utility to round
doubles.
2003-01-02 16:32:54 +00:00
Just van Rossum d35c6db526 Ugh, zipimport is virtually broken in 2.3a1 :-( It worked by accident in
the test set as it only tested with a zip archive in the current directory,
but it doesn't work at all for packages when the zip archive was specified
as an absolute path. It's a real embarrassing bug: a strchr call should
have been strrchr; fever apparently implies dyslexia.

Second stupid bug: the zipimport test failed with a name error
__importer__ (which I had renamed to __loader__ everywhere but here).
I would've sworn I ran the test after that change but that can't be true.
What I don't understand that noone reported a failing test_zipimport.py
before the release of 2.3a1.

2003-01-02 03:14:59 +00:00
Tim Peters f36151556f A quicker astimezone() implementation, rehabilitating an earlier
suggestion from Guido, along with a formal correctness proof of the
trickiest bit.  The intricacy of the proof reveals how delicate this
is, but also how robust the conclusion:  correctness doesn't rely on
dst() returning +- one hour (not all real time zones do!), it only
relies on:

1. That dst() returns a (any) non-zero value if and only if daylight
   time is in effect.

and

2. That the tzinfo subclass implements a consistent notion of time zone.

The meaning of "consistent" was a hidden assumption, which is now an
explicit requirement in the docs.  Alas, it's an unverifiable (by the
datetime implementation) requirement, but so it goes.

Tim Peters b5a16f3375 datetimetz_astimezone(): Speed optimizations -- although I'd rather
find a more elegant algorithm (OTOH, the hairy new implementation allows
user-written tzinfo classes to be elegant, so it's a big win even if
astimezone() remains hairy).

Darn!  I've only got 10 minutes left to get falling-down drunk!  I suppose
I'll have to smoke crack instead now.

Jeremy Hylton accb62b28e SF patch [ 597919 ] compiler package and SET_LINENO
A variety of changes from Michael Hudson to get the compiler working
with 2.3.  The primary change is the handling of SET_LINENO:

# The set_lineno() function and the explicit emit() calls for
# SET_LINENO below are only used to generate the line number table.
# As of Python 2.3, the interpreter does not have a SET_LINENO
# instruction.  pyassem treats SET_LINENO opcodes as a special case.

A few other small changes:
 - Remove unused code from pycodegen and pyassem.
 - Fix error handling in parsermodule.  When PyParser_SimplerParseString()
   fails, it sets an exception with detailed info.  The parsermodule
   was clobbering that exception and replacing it was a generic
   "could not parse string" exception.  Keep the original exception.
2002-12-31 18:17:44 +00:00
Tim Peters 521fc15e62 A new, and much hairier, implementation of astimezone(), building on
an idea from Guido.  This restores that the datetime implementation
never passes a datetime d to a tzinfo method unless d.tzinfo is the
tzinfo instance whose method is being called.  That in turn allows
enormous simplifications in user-written tzinfo classes (see the Python
sandbox US.py and EU.py for fully fleshed-out examples).

d.astimezone(tz) also raises ValueError now if d lands in the one hour
of the year that can't be expressed in tz (this can happen iff tz models
both standard and daylight time).  That it used to return a nonsense
result always ate at me, and it turned out that it seemed impossible to
force a consistent nonsense result under the new implementation (which
doesn't know anything about how tzinfo classes implement their methods --
it can only infer properties indirectly).  Guido doesn't like this --
expect it to change.

New tests of conversion between adjacent DST-aware timezones don't pass
yet, and are commented out.

Running the datetime tests in a loop under a debug build leaks 9
references per test run, but I don't believe the datetime code is the
cause (it didn't leak the last time I changed the C code, and the leak
is the same if I disable all the tests that invoke the only function
that changed here).  I'll pursue that next.

Greg Ward 2d6f9a9a86 Yet another renaming of some mixer methods:
devices(), stereodevices(), recdevices() ->
  controls(), stereocontrols(), reccontrols()

Based on recommendation of Hannu Savolainen <hannu@opensound.com>:

  The right term to use for things like bass/treble/mic/vol/etc is
  "control".

  "Device" refers to different mixer devices (/dev/mixer0 to /dev/mixerN).

  "Channel" cannot be used because it refers to mono/stereo/multich
  channels. In fact most mixer controls have left/right channels so ...
2002-12-31 02:54:43 +00:00

Tim Peters bad8ff089a A step on the way to making tzinfo classes writable by mortals: get rid
of the timetz case.  A tzinfo method will always see a datetimetz arg,

a datetimetz argument belonging to a different timezone.  That will get
fixed next.

Guido van Rossum faf5e4d48f Patch 659834 by Magnus Lie Hetland:
Check for readline 2.2 features.  This should make it possible to

different (a space is always added).

Tim Peters d684415572 I give up: unless I write my own strftime by hand, datetime just can't

1900.
2002-12-22 20:58:42 +00:00
Tim Peters 83b85f1d6c Python's strftime implementation does strange things with the year,
such that the datetime tests failed if the envar PYTHON2K was set.
This is an utter mess, and the datetime module's strftime functions
inherit it.  I suspect that, regardless of the PYTHON2K setting, and
regardless of platform limitations, the datetime strftime wrappers
will end up delivering nonsense results (or bogus exceptions) for
any year before 1900.  I should probably just refuse to accept years
earlier than that -- else we'll have to implement strftime() by hand.

tzinfo.{utcoffset,dst)() can now return a timedelta (or an int, or None).

Curiously, this was much easier to do in the C implementation than in the
Python implementation (which lives in the Zope3 code tree) -- the C code
already had lots of hair to extract C ints from offset objects, and used
C ints internally.
