Neal Norwitz e5e5aa4ea6 Do a better job of not inlining Py_ADDRESS_IN_RANGE() for newer gcc's.
Perhaps Py_NO_INLINE should be moved to pyport.h or some other header?

Neal Norwitz 6576bd844f Prevent name pollution by making lots of internal functions static. 2005-11-13 18:41:28 +00:00
Armin Rigo c6686b7c7e Added proper reflection on instances of <type 'method-wrapper'>, e.g.
'[].__add__', to match what the other internal descriptor types provide:
'__objclass__' attribute, '__self__' member, and reasonable repr and
comparison.

Added a test.

Michael W. Hudson b2308bb9be Fix bug:
[ 1327110 ] wrong TypeError traceback in generator expressions

by removing the code that can stomp on the users' TypeError raised by the
iterable argument to ''.join() -- PySequence_Fast (now?) gives a perfectly
reasonable message itself.  Also, a couple of tests.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Marc-André Lemburg 2cb94aba12 Enhance the performance of two important Unicode character
type lookups: whitespace and linebreak.

These lookup tables are from the Python 1.6 version with the addition
of the 205F code point which was added as whitespace code point to Unicode
since then.

Walter Dörwald d1c1e10f70 Part of SF patch #1313939: Speedup charmap decoding by extending
PyUnicode_DecodeCharmap() the accept a unicode string as the mapping
argument which is used as a mapping table.

This code isn't used by any of the codecs yet.

Guido van Rossum 630db60a55 - On 64-bit platforms, when __len__() returns a value that cannot be
represented as a C int, raise OverflowError.

(Forward port from 2.4.2; the patch to classobject.c was already in
but needed a correction in the error message text.)
2005-09-20 18:49:54 +00:00
Guido van Rossum ba3e6ec0c9 A minor fix for 64-bit platforms: when __len__() returns Python int
containing a value that doesn't fit in a C int, raise OverflowError
rather than truncating silently (and having 50% chance of hitting the
"it should be >= 0" error).
2005-09-19 22:42:41 +00:00
Raymond Hettinger 9bda1d6f64 No longer ignore exceptions raised by comparisons during key lookup.
Inspired by Armin Rigo's suggestion to do the same with dictionaries.

Neil Schemenauer ab61923637 Fix bug in last checkin (2.231). To match previous behavior, unicode
subclasses should be substituted as-is and not have tp_str called on
them.

Walter Dörwald a47d1c08d0 SF bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
about illegal code points. The codec now supports PEP 293 style error handlers.
(This is a variant of the Nik Haldimann's patch that detects truncated data)

Raymond Hettinger 9c1491f37c * Add a fast equality check path for frozensets where the hash value has
already been computed.
* Apply a GET_SIZE macro().

Raymond Hettinger a710b331da SF bug #1242657: list(obj) can swallow KeyboardInterrupt
Fix over-aggressive PyErr_Clear().  The same code fragment appears in
various guises in list.extend(), map(), filter(), zip(), and internally
in PySequence_Tuple().

Raymond Hettinger f81e45023e Fix nits. 2005-08-17 02:19:36 +00:00
Raymond Hettinger f408ddf4a0 Results of a line-by-line comparison back to dictobject.c.
* set_merge() cannot assume that the table doesn't resize during iteration.

* convert some unnecessary tests to asserts -- they were necessary in
  dictobject.c because PyDict_Next() is a public function.  The same is
  not true for set_next().

* re-arrange the order of functions to more closely match the order
  in dictobject.c.  This makes it must easier to compare the two
  and ought to simplify any issues of maintaining both.

Raymond Hettinger ce8185e642 More function re-ordering (placing like functions together). 2005-08-13 09:28:48 +00:00
Raymond Hettinger ed6c1ef8c3 * Bring lookkey() and lookkey_string() closer to dict version.
* Use set_next() for looping in issubset() and frozenset_hash().
* Re-order the presentation of cmp and hash functions.
2005-08-13 08:28:03 +00:00
Phillip J. Eby 00148226df Fix a too-aggressive assert (see SF#1257960). Previously, gen_iternext
was never called during interpreter shutdown GC, so the f_back!=NULL
assertion was correct.  Now that generators get close()d during GC,
the assertion was being triggered because the generator close() was being
called as the top-level frame.  However, nothing actually is broken by
this; it's just that the condition was unexpected in previous Python
versions.
2005-08-13 03:29:00 +00:00
Raymond Hettinger b02c35e208 * Fix SF #1257731. Make __contains__(), remove(), and discard() only do
a frozenset conversion when the initial search attempt fails with a
  TypeError and the key is some type of set.  Add a testcase.

* Eliminate a duplicate if-stmt.
2005-08-12 20:48:39 +00:00
Neil Schemenauer cf52c07843 Change the %s format specifier for str objects so that it returns a
unicode instance if the argument is not an instance of basestring and
calling __str__ on the argument returns a unicode instance.
2005-08-12 17:34:58 +00:00
Raymond Hettinger c991db240c * Add short-circuit code for in-place operations with self (such as
s|=s, s&=s, s-=s, or s^=s).  Add related tests.

* Improve names for several variables and functions.

* Provide alternate table access functions (next, contains, add, and discard)
  that work with an entry argument instead of just a key.  This improves
  set-vs-set operations because we already have a hash value for each key
  and can avoid unnecessary calls to PyObject_Hash().  Provides a 5% to 20%
  speed-up for quick hashing elements like strings and integers.  Provides
  much more substantial improvements for slow hashing elements like tuples
  or objects defining a custom __hash__() function.

* Have difference operations resize() when 1/5 of the elements are dummies.
  Formerly, it was 1/6.  The new ratio triggers less frequently and only
  in cases that it can resize quicker and with greater benefit.  The right
  answer is probably either 1/4, 1/5, or 1/6.  Picked the middle value for
  an even trade-off between resize time and the space/time costs of dummy
  entries.
2005-08-11 07:58:45 +00:00
Raymond Hettinger bc841a1464 * Bring in INIT_NONZERO_SET_SLOTS macro from dictionary code.
* Bring in free list from dictionary code.
* Improve several comments.
* Differencing can leave many dummy entries.  If more than
  1/6 are dummies, then resize them away.
* Factor-out common code with new macro, PyAnySet_CheckExact.
2005-08-07 13:02:53 +00:00
Raymond Hettinger 99220fabb1 * Removed checked_error flag which no longer provides any benefit.
* Have issubset() control its own loop instead of using set_next_internal().
2005-08-06 18:57:13 +00:00
Raymond Hettinger 5ba0cbe392 * set_new() doesn't need to zero the structure a second time after tp_alloc
has already done the job.
* Use a macro form of PyErr_Occurred() inside the set_lookkey() function.
2005-08-06 18:31:24 +00:00
Raymond Hettinger fe889f3c62 Factor away a redundant clear() function. 2005-08-06 05:43:39 +00:00
Raymond Hettinger a580c47c6d * Improve a variable name: entry0 --> table.
* Give set_lookkey_string() a fast alternate path when no dummy entries
  are present.
* Have set_swap_bodies() reset the hash field to -1 whenever either of
  bodies is not a frozenset.  Maintains the invariant of regular sets
  always having -1 in the hash field; otherwise, any mutation would make
  the hash value invalid.
* Use an entry pointer to simplify the code in frozenset_hash().
2005-08-05 17:19:54 +00:00
Raymond Hettinger a9d9936d10 * Move copyright notice to top and indicate derivation from sets.py and
dictobject.c.
* Have frozenset_hash() use entry->hash instead of re-computing each
  individual hash with PyObject_Hash(o);
* Finalize the dummy entry before a system exit.

Raymond Hettinger 67962ab1bb Model set.pop() after dict.popitem(). 2005-08-02 03:45:16 +00:00
Phillip J. Eby 0d6615fd29 PEP 342 implementation. Per Guido's comments, the generator throw()
method still needs to support string exceptions, and allow None for the
third argument.  Documentation updates are needed, too.
2005-08-02 00:46:46 +00:00
Raymond Hettinger d794666048 * Improve code for the empty frozenset singleton:
- Handle both frozenset() and frozenset([]).
  - Do not use singleton for frozenset subclasses.
  - Finalize the singleton.
  - Add test cases.
* Factor-out set_update_internal() from set_update().  Simplifies the
  code for several internal callers.
* Factor constant expressions out of loop in set_merge_internal().
* Minor comment touch-ups.
