Raymond Hettinger 8421d714d0 Removed unused initialization and the uninteresting comment. 2016-04-29 01:37:05 -07:00
Serhiy Storchaka fa070298e9 Issue #26880: Removed redundant checks in set.__init__. 2016-04-29 11:31:52 +03:00
Serhiy Storchaka ab479c49d3 Issue #26494: Fixed crash on iterating exhausting iterators. 
Affected classes are generic sequence iterators, iterators of str, bytes,
bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
views and os.scandir() iterator.

Raymond Hettinger 3625af5f21 Moved misplaced functions to the section for C API functions. 2016-03-27 01:15:07 -07:00
Raymond Hettinger 2c257ab0f8 Responsibility for argument checking belongs in set.__init__() rather than set.__new__(). 
See dict.__new__() and list.__new__() for comparison.  Neither of those examine or touch
args or kwds.  That work is done in the __init__() methods.

Raymond Hettinger 73799b181e Change add/contains/discard calls to pass the key and hash instead of an entry struct. 2015-07-05 16:06:10 -07:00
Raymond Hettinger dc28d5a198 Clean-up call patterns for add/contains/discard to better match the caller's needs. 2015-07-05 10:03:20 -07:00
Raymond Hettinger ac2ef65c32 Make the unicode equality test an external function rather than in-lining it. 
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.

Raymond Hettinger e186c7674c Make sure the dummy percentage calculation won't overflow. 2015-07-04 11:28:35 -07:00

Raymond Hettinger b322326f48 Minor nit: Make the style of checking error return values more consistent. 2015-07-03 23:37:16 -07:00
Raymond Hettinger 4897300276 Minor factoring: move redundant resize scaling logic into the resize function. 2015-07-03 20:00:03 -07:00
Raymond Hettinger 3c1f52e829 Call set_lookkey() directly to avoid unnecessary memory spills and reloads. 2015-07-03 18:31:09 -07:00
Raymond Hettinger 15f0869609 Move insertion resize logic into set_insert_key(). 
Simplifies the code a little bit and does the resize check
only when a new key is added (giving a small speed up in
the case where the key already exists).

Fixes possible bug in set_merge() where the set_insert_key()
call relies on a big resize at the start to make enough room
for the keys but is vulnerable to a comparision callback that
could cause the table to shrink in the middle of the merge.

Also, changed the resize threshold from two-thirds of the
mask+1 to just two-thirds.  The plus one offset gave no
real benefit (afterall, the two-thirds mark is just a
heuristic and isn't a precise cut-off).

Raymond Hettinger 7e3592dca6 Harmonize the bottom of the outer loop with its entry point 
giving a small simplification.  Timings show that hash
pre-check seems only benefit the inner-loop (the linear probes).

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.

Raymond Hettinger 4ea9080da9 Improve code clarity by removing two unattractive macros. 2013-09-07 21:01:29 -07:00
Raymond Hettinger 8f8839e10a Remove the freelist scheme for setobjects. 
The setobject freelist was consuming memory but not providing much value.
Even when a freelisted setobject was available, most of the setobject
fields still needed to be initialized and the small table still required
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 69492dab07 Factor-out the common code for setting a KeyError. 2013-09-02 15:59:26 -07:00
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.

Raymond Hettinger afe890923f Tighten-up the lookkey() logic and beautify the code a bit. 
Use less code by moving many of the steps from the initial

Beautify the code but keep the overall logic unchanged.

Raymond Hettinger ae9e616a00 Issue 18772: Restore set dummy object back to unicode and restore the identity checks in lookkey(). 
The Gdb prettyprint plugin depended on the dummy object being displayable.
Other solutions besides a unicode object are possible.  For now, get it
back up and running.

The identity checks in lookkey() need to be there to prevent the dummy
object from leaking through Py_RichCompareBool() into user code in the
rare circumstance where the dummy's hash value exactly matches the hash
value of the actual key being looked up.

Raymond Hettinger c629d4c9a2 Replace outdated optimization with clearer code that compiles better. 
Letting the compiler decide how to optimize the multiply by five
gives it the freedom to make better choices for the best technique
for a given target machine.

For example, GCC on x86_64 produces a little bit better code:

Old-way (3 steps with a data dependency between each step):

    shrq    $5, %r13
    leaq    1(%rbx,%r13), %rax
    leaq    (%rax,%rbx,4), %rbx

New-way (3 steps with no dependency between the first two steps
         which can be run in parallel):

    leaq    (%rbx,%rbx,4), %rax     # i*5
    shrq    $5, %r13                # perturb >>= PERTURB_SHIFT
    leaq    1(%r13,%rax), %rbx      # 1 + perturb + i*5

Gregory P. Smith c2176e46d7 Fix the internals of our hash functions to used unsigned values during hash 
computation as the overflow behavior of signed integers is undefined.

NOTE: This change is smaller compared to 3.2 as much of this cleanup had
already been done.  I added the comment that my change in 3.2 added so that the
code would match up.  Otherwise this just adds or synchronizes appropriate UL
designations on some constants to be pedantic.

In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent.

Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).

Cleanup only - no functionality or hash values change.
