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.

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

Changed hex() and oct() again, to never emit a '-' sign.

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.

Some more tuning of quicksort: use pointers instead of indexing.
1996-12-11 23:57:39 +00:00
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.

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).

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.

Added __name__ attribute to class instance method objects.

6ec3c653da
Implemented two new functions in sys:
...
getcounts() returns a list of counts of allocations and
deallocations for all different object types.
getobjects(n [, type ]) returns a list of recently allocated
and not-yet-freed objects of the given type (all
objects if no type given). Only the n most recent
(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS. Note that
everything must be compiled with these options!
