Guido van Rossum 037b2205e8 Moved PyObject_{Get,Set}Attr to object.c. 
Fixed two 'return NULL' that should be 'return -1'.
 1997-05-20 18:35:19 +00:00
Guido van Rossum 98ff96adba Moved PyObject_{Get,Set}Attr here (from dictobject) and add PyObject_HasAttr. 1997-05-20 18:34:44 +00:00
Guido van Rossum 967839473a Got rid of c_error in favor of errno (and EDOM/ERANGE). 
Assume that errno usage is thread-safe -- most vendors do this by
making in a macro that refers to a per-thread storage area.
 1997-05-20 18:21:34 +00:00
Guido van Rossum 3cca24570e Got rid of all the last_name_* bogosities. I don't think the 
complexity saved much any more.  A simple benchmark (grail) showed
that there were 3 times as many misses as hits, and the same number of
times again the code was bypassed altogether due to the existence of
setattro/getattro.

Guido van Rossum d0c87ee6c4 Oops, another forgotten renaming: varobject -> PyVarObject. 1997-05-15 21:31:03 +00:00
Guido van Rossum e61093c218 Fix reversed test for failure in PySequence_List() and PySequence_Tuple(). 
This broke cPickle.
 1997-05-14 18:43:29 +00:00
Guido van Rossum 9637432265 Renamed mappingobject.c to dictobject.c. 1997-05-13 21:05:38 +00:00
Guido van Rossum a9e7a81137 Renamed from mappingobject.c to dictobject.c. 
(Sorry Jack, all your projects will have to be changed again. :-( )

Guido van Rossum 93ad0df06c Faster floating point allocator, same idea as the int allocator. 
By Aaron Watters.
 1997-05-13 21:00:42 +00:00
Guido van Rossum 789a1613a0 Add optional 'sizehint' argument to readlines(). After approximately 
this many bytes have been read, readlines stops.  Because of
buffering, the amount of bytes read is usually at least 8K more than
the hint.

Also changed read() and readline() to use PyArg_ParseTuple().

(Note that the *previous* checkin also fixed error handling and
narrowed the range of thread unblocking for all methods using
fread().)
 1997-05-10 22:33:55 +00:00
Guido van Rossum 6263d5451c Rewrite readlines() to speed it up -- about a factor of 2 on my 
Indigo2, reading a 9Meg file from the local disk.
 1997-05-10 22:07:25 +00:00
Guido van Rossum 5449b6e123 Speed up read() (i.e. read till EOF) considerably by doing a stat() to 
see if we can guess the #bytes until the end of the file.  If we
can't, increment the buffer size increments up to 0.5Meg to avoid
realloc'ing too much.
 1997-05-09 22:27:31 +00:00
Guido van Rossum 0add15f6a5 removed last #ifdef SUPPORT_OBSOLETE_ACCESS bits. 1997-05-09 01:07:15 +00:00
Guido van Rossum b819914263 Fix by Mark Hammond to enable truncate() on Windows. 1997-05-06 15:23:24 +00:00
Guido van Rossum fdf95dd525 Checkin of Jack's buffer mods. 
Not really checked, but didn't fail any tests either...
 1997-05-05 22:15:02 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management. 
All per-thread globals are moved into a struct which is manipulated
separately.
 1997-05-05 20:56:21 +00:00
Guido van Rossum c0b618a2cc Quickly renamed the last directory. 1997-05-02 03:12:38 +00:00
Guido van Rossum 1875247549 Quickly renamed. 1997-04-29 14:49:28 +00:00
Guido van Rossum 3648884490 (Jack:) Align mapping entries to 4-words if USE_CACHE_ALIGNED is defined. 1997-04-11 19:14:07 +00:00
Guido van Rossum 2095d24842 Tweaks to keep the Microsoft compiler quiet. 1997-04-09 19:41:24 +00:00
Guido van Rossum 8017767420 Remove unused variable. 1997-04-09 18:22:28 +00:00
Guido van Rossum 6191551ad6 Remove a redundant XINCREF(value). This caused the reference count of 
all locals to be upped by one when `from <module> import <whatever>'
was executed.
 1997-04-03 18:31:43 +00:00
Guido van Rossum 4669fb474b Several fixes reported by jim F. 1997-04-02 05:31:09 +00:00
Guido van Rossum c054d70aee Get rid of .conj pseudo data attribute for complex numbers. 
Add __members__ attribute.
 1997-04-01 03:12:33 +00:00
Guido van Rossum fb8f1cadb2 Add clear() method to dictionary objects. 1997-03-21 21:55:12 +00:00
Guido van Rossum f2e499b1d7 New long_lshift, without restriction on size of shift count, by Tim Peters. 
This makes it possible to write 1L<<1000000, memory permitting.
 1997-03-16 00:37:59 +00:00
Guido van Rossum 45b83915f8 New form of PyFPE_END_PROTECT macro. 1997-03-14 04:32:50 +00:00

integer overflow in << operator.
 1997-03-05 00:45:43 +00:00
Guido van Rossum 09e6ad0c1e Changes for Lee Busby's SIGFPE patch set. 
Surround various f.p. operations with  PyFPE_{START,END}_PROTECT macros.
 1997-02-14 22:54:21 +00:00
Guido van Rossum 0f4bbd2f34 Keep gcc -Wall happy. 1997-02-14 21:12:56 +00:00
Guido van Rossum 36b9f7908a Slight tweak: in string_hash(), if the hash hasn't been computed yet, 
and if there's a pointer to an interned version of the string, use its
hash and store its hash in this object, rather than recomputing it.
 1997-02-14 16:29:22 +00:00
Guido van Rossum 7582bfb60a Kill all local variables when the frame is deallocated (moved here 
from ceval.c).

Wrapped a long line.
 1997-02-14 16:27:29 +00:00
Guido van Rossum efb4609c4a Small lookmapping nits: 
- remove bogus initialization using uninitialized i
- derive initial incr from hash
- copy mp->ma_table into a local variable
 1997-01-29 15:53:56 +00:00
Guido van Rossum 4acdc2327f Fix bug reported by Per Lindqvist: "%#06x" % 1 stuck the 0 padding 
in front of the 0x, like such: "0000x1".
 1997-01-29 06:00:24 +00:00
Guido van Rossum 9e5656ca3f Final three poly table entries corrected by Tim Peters. 
Reindented the whole table.
 1997-01-29 04:45:16 +00:00
Guido van Rossum 16e93a8d59 Changed the lookup algorithm again, based on Reimer Behrends's post. 
The table size is now constrained to be a power of two, and we use a
variable increment based on GF(2^n)-{0} (not that I have the faintest
idea what that is :-) which helps avoid the expensive '%' operation.

Some of the entries in the table of polynomials have been modified
according to a post by Tim Peters.
 1997-01-28 00:00:11 +00:00
Guido van Rossum 747596a491 When a recycled frame has more local+stack slots than needed, 
give the extra slots to the stack rather than than forgetting about
them (this reduces the number of reallocs done).
 1997-01-24 04:00:21 +00:00
Guido van Rossum ca756f2a1d Forget keeping track of whether a dictionary contains all interned 
string keys.  Just doing a pointer compare before the string compare
(in fact before the hash compare!) is just as fast.
 1997-01-23 19:39:29 +00:00
Guido van Rossum e0e696282f Added PyCObject_Import. 1997-01-22 20:48:48 +00:00
Guido van Rossum a04d47b319 Don't use static buffers internally for formatstring(). 1997-01-21 16:12:09 +00:00
Guido van Rossum 3bb63a8dbe Bugfix: remove ref to fast before it's defined. 1997-01-20 04:29:16 +00:00
Guido van Rossum f3e85a0356 Changes that appear to give another 12% speedup. 
Rather than allocating a list object for the fast locals and another
(extensible one) for the value stack and allocating the block stack
dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS
from compile.h), and stick the locals and value stack at the end of
the object (this is now possible since the stack size is known
beforehand).  Get rid of the owner field and the nvalues argument --
it is available in the code object, like nlocals.

This requires small changes in ceval.c only.
 1997-01-20 04:20:52 +00:00
Guido van Rossum a412d24be0 Intern the various string objects created to speed up lookups. 1997-01-18 07:59:12 +00:00
Guido van Rossum b56933ed2e Intern the strings "__builtins__". 1997-01-18 07:58:41 +00:00
Guido van Rossum c6d0670f1b Intern the strings created in getattr() and setattr(). 1997-01-18 07:57:16 +00:00
Guido van Rossum 2a61e7428d String interning. 1997-01-18 07:55:05 +00:00

Guido van Rossum 7d18159614 Rewrote lookmapping() according to suggestions by Jyrki Alakuijala. 1997-01-16 21:06:45 +00:00
Guido van Rossum 6f72f97c03 Increased buffer sizes used by hex() and oct() -- on 64-bit or 128-bit 
machines, the string may get longer than 20 characters!
 1997-01-14 15:43:41 +00:00
Guido van Rossum ebee0256f3 Changed hex() and oct() again, to never emit a '-' sign. 1997-01-12 19:48:03 +00:00
Guido van Rossum 919cf1aff1 New, better hash for floating point and complex 1997-01-11 19:26:21 +00:00
Guido van Rossum 80dd9b6672 Subtle change to hex/oct formatting so the largest negative number 
does not receive a minus sign.
 1997-01-10 17:39:30 +00:00
Guido van Rossum 541cdd84ac Fix overflow test for multiply to catch some cases it missed. 
Added warning about dependency of float/complex hash on int hash.
 1997-01-06 22:53:20 +00:00
Guido van Rossum 53756b1097 Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong(). 1997-01-03 17:14:46 +00:00
Guido van Rossum babab6869f Removed all traces of accessobject.c. 1996-12-25 19:22:49 +00:00
Barry Warsaw f90eddef5d PySequence_Index(): set exception when object is not found in 
sequence, otherwise

operator.indexOf([4, 3, 2, 1], 9) would raise a SystemError!

Note: it might be wise to double check all these functions.  I haven't
done that yet.
 1996-12-18 19:32:18 +00:00
Guido van Rossum 0969ad213d Better tuple hash function. 1996-12-16 17:55:46 +00:00
Guido van Rossum cc15b42e59 Change comment about MINSIZE -- 10 is optimal for Python. 1996-12-16 03:32:39 +00:00
Guido van Rossum 3176bb1df2 Some more tuning of quicksort: use pointers instead of indexing. 1996-12-11 23:57:39 +00:00
Guido van Rossum 3f236dee3a Added new quicksort implementation, tailored to sorting arrays of 
object pointers.  Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.

Thanks to discussions with Tim Peters.
 1996-12-10 23:55:39 +00:00
Guido van Rossum 067998f35e Add const to error and newstring functions 1996-12-10 15:33:34 +00:00

Guido van Rossum da9c2710c7 Make gcc -Wall happy 1996-12-05 21:58:58 +00:00
Guido van Rossum 472c04f18f Fix newlongobject so it will work for 64-bit as well as 32-bit hardware 
(although for 32-bit hardware it's a bit slower than it was).

Make gcc -Wall happy.
 1996-12-05 21:57:21 +00:00
Guido van Rossum a0a69b8b42 Experimental new implementation of dictionary comparison. This 
defines that a shorter dictionary is always smaller than a longer one.
For dictionaries of the same size, the smallest differing element
determines the outcome (which yields the same results as before,
without explicit sorting).
 1996-12-05 21:55:55 +00:00
Guido van Rossum 685a38ea94 Make gcc -Wall happy. 1996-12-05 21:54:17 +00:00

Make gcc -Wall happy.
 1996-12-05 21:52:32 +00:00
Guido van Rossum 3c5936afc5 Added missing PySequence_List. 
Correct typo in error msg (expec[t]ed).
Make gcc -Wall happy.
 1996-12-05 21:51:24 +00:00

Guido van Rossum fde7a75b78 Fixed compare function to do first char comparison in unsigned mode, 
for consistency with the way other characters are compared.
 1996-10-23 14:19:40 +00:00
Guido van Rossum 8bcf369cf9 Support passing in an empty dictionary of keywords to newinstanceobject. 1996-10-21 15:12:32 +00:00
Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should 
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
 1996-10-11 16:25:41 +00:00
Guido van Rossum 336c699236 Fix subtle bug detected by Jim F. 1996-09-30 22:00:50 +00:00

Guido van Rossum 3be12e97cd Properly(?) implemented remainder and divmod (Tim Hochberg) 1996-09-12 20:56:18 +00:00
Guido van Rossum d4ab3cde8e Raise exception instead of dropping imag part for conversion to int, 
long, float.

Raise exception instead of dumping core for remainder and divmod.
 1996-09-11 22:54:37 +00:00
