Raymond Hettinger ed741d4ff0 A hybrid of and-masking and a conditional-set-to-zero produce even faster search loop. 2015-01-18 21:25:15 -08:00
Raymond Hettinger bd9b200b87 Update copyright for 2015 updates. 2015-01-18 16:10:30 -08:00
Raymond Hettinger 9cd6a789c6 Clean-up, simplify, and slightly speed-up bounds logic in set_pop(). 
Elsewhere in the setobject.c code we do a bitwise-and with the mask
instead of using a conditional to reset to zero on wrap-around.
Using that same technique here use gives cleaner, faster, and more
consistent code.

Antoine Pitrou 9086f9260f Issue #22604: Fix assertion error in debug mode when dividing a complex number by (nan+0j). 2014-10-10 23:49:32 +02:00
R David Murray 861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

Serhiy Storchaka 94ee389308 Issue #19619: Blacklist non-text codecs in method API 
str.encode, bytes.decode and bytearray.decode now use an

rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.

The latter mechanism remains in place for third party non-text
encodings.

Nick Coghlan c72e4e6dcc Issue #19619: Blacklist non-text codecs in method API 
str.encode, bytes.decode and bytearray.decode now use an

rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.

The latter mechanism remains in place for third party non-text
encodings.

PyByteArray_Resize() failure: leave the bytearray object in an consistent state.

If growth < 0, handling the memory allocation failure is tricky here because
the bytearray object has already been modified.  If lo != 0, the operation is
completed, but a MemoryError is still raised and the memory block is not
shrinked. If lo == 0, the bytearray is restored in its previous state and a
MemoryError is raised.

The setobject freelist was consuming memory but not providing much value.

a memset().  This meant that the custom freelisting scheme for sets was
providing almost no incremental benefit over the default Python freelist
scheme used by _PyObject_Malloc() in Objects/obmalloc.c.

Raymond Hettinger a35adf5b09 Instead of XORed indicies, switch to a hybrid of linear probing and open addressing. 
Modern processors tend to make consecutive memory accesses cheaper than
random probes into memory.

Small sets can fit into L1 cache, so they get less benefit.  But they do
come out ahead because the consecutive probes don't probe the same key
more than once and because the randomization step occurs less frequently
(or not at all).

For the open addressing step, putting the perturb shift before the index
calculation gets the upper bits into play sooner.
