Hello, anyone? :)


Kia ora,

I'm requesting access to wiki to be able to write the RFC on
implementing missing pdo_sqlite features, following pull request

If this is not displayed properly please visit our results page here: 
http://languagesperformance.intel.com/bad-benchmark-results-for-php-master-2017-08-30/

Note: Benchmark results for Wordpress, Drupal, MediaWiki are measured in
fetches/second while all others are measured in seconds.
More details on measurements methodology at: 
https://01.org/lp/documentation/php-environment-setup.

Subject Label Legend:
Attributes are determined based on the performance evolution of the workloads
compared to the previous measurement iteration.
NEUTRAL: performance did not change by more than 1% for any workload
GOOD: performance improved by more than 1% for at least one workload and there
is no regression greater than 1%
BAD: performance dropped by more than 1% for at least one workload and there is
no improvement greater than 1%
UGLY: performance improved by more than 1% for at least one workload and also
dropped by more than 1% for at least one workload


Our lab does a nightly source pull and build of the PHP project and measures
performance changes against the previous stable version and the previous nightly
measurement. This is provided as a service to the community so that quality
issues with current hardware can be identified quickly.

Intel technologies' features and benefits depend on system configuration and may
require enabled hardware, software or service activation. Performance varies
depending on system configuration.

[PHP-DEV] add Fiber (sackful coroutine) support

[Haitao Lv]

Hi, All,

The generator has been introduced in PHP 5.5. And we can it pause a function 
execution.
With these feature, we can schedule multi io task in userland without blocking.

More details can be found at [Nikic].

And there is also some asynchronous frameworks like [AMP], which allow 
programer to 
code like blocking, but run asynchronously.

However, like python's generator, lua's coroutine, javascript's async/await, 
php's
generator also is a stackless coroutine implementation. We cannot pause a 
function call
in it's sub function call. This is the reason that frameworks like [AMP] has 
many wrapper,
is hard to understand, and almost impossible to be used to implement real but 
complex system.

So I propose to introduce the sackful coroutine, aka Fiber, support for PHP. 
And the possible
API like this,

>  function foo($a)
> {
>   $b = await $a + 1;
>   echo $b;
> }
> 
> function bar()
> {
>   foo();
> }
> 
> $f = new Fiber(function($a) {
>   bar($a);
>   return 3;
> });
> 
> $c = $f->resume(1);
> // 1 will be passed to lambda, then bar
> // bar call foo, and the **await** in foo paused this execution
> // and make the return value of resume as $a + 1
> // so $c is 2
> 
> $c = $f->resume(3);
> // resume the execution by previous await, and the $b in foo
> // will be assigned a value of 3
> // so foo echo 3 and return and then the lambda return
> // and the resume got a return value of 3. so $c is 3.

So the Fiber API is a little like the Generator API, but is more simple yet 
powerful. So there
is no need to distinct $generator->current(), $generator->send(), and 
$generator->getReturn().

I made a more complex example at [FIREPHP].And I also make a [PR] for comment.

All comment are welcome. Thanks.
