Hi,
If nobody is working on it this task, I may take it. (I will keep on
working on my project as long as possible, but I have too much on my
head right now to do 'creative' stuff - need something with clearly
defined goals).
If Sebastian or Travis (they mentored this project, didn't they?)

Hello,
I was again in bed for few days:/// Hope this time I have fully
recovered:/
Anyways the patch for today is for auxiliary php_charmask function
used by trim, str_word_count and addcslashes. It is basically just
bunch of if-statements. But it can sped up by reordering them.
Original n
e no room for ambiguity. For example,
if you don't plan to do any benchmarks, say so.
Keep up the good work,

Hello,
Here goes first diff - to keep it simple and avoid confusion I will
post them one-by-one after the previous is accepted/rejected.
Optimization of STRRPOS/STRRIPOS for PHP_5_3.
2 things are changed:
* implementation of search loop from theta(NM) to o(N), omega(NM) -
it is now the same
Hi,
I am also sorry for delay - got ill recently and spend a day in bed
after night at emergency. I am working on other things now, and hope
to post some patches soon. I will create patch for zend_memnstr as
you suggest and post it here probably tomorrow. I have some ideas/
implementations/
Hello again
I have setup small page where I am publishing all the profiling and
evaluation results. It is here: http://83.168.205.202/~michal/
standard15/
So far I have put there function usage profile, zend_memnstr
analysis, stripos and strrpos analysis including some charts etc. CVS
diffs
I;ve just noticed that the diff I posted is form my test-bed, not the actual
final version. the code should be:
if (needle_len == 1){
return (char *)memchr(p, *needle, (end-p));
}
instead of
+ if (needle_len == 1){
+ return (char *)memchr(p, *needle, (end-p+1))
Hello again

Hello everybody,
I have done small comparison of the 3 algorithms: the original zend_memnstr
implementation, KMP, and Boyer-Moore (inefficient, "book" implementation).
The first part - real life data. I have collected the data about the
parameters passed to ZEND_MEMNSTR (not only while it is calle

Hello,
I am Michal, and I will work on algorithm optimizations. Thanks for

this project. I am looking forward to start:)
