I wanted to test the new stable pthreads extension for PHP on my Arch Linux 64-bit.
to install the pthreads extension using pecl you are required to use a compiled version
of PHP with the the thread safety support flag --enable-maintainer-zts.
the most clean way on Arch would be then rebuild the original package with the flag.
this was very important to me to keep my PHP as stable as possible.
so here's what you should do ...
First checked what packages dependent on the 'php' package:
pacman -Qii php
Got the following outout:
:: php-apache: requires php
:: php-apcu: requires php
:: php-mcrypt: requires php
:: php-pear: requires php
:: php-pgsql: requires php
:: xdebug: requires php
Remove all of them including 'php', so:
pacman -R php php-apache php-apcu php-mcrypt php-pear php-pgsql xdebug
Clone Archlinux's official package repository
cd /opt/
git clone git://projects.archlinux.org/svntogit/packages.git
cd packages/php/trunk
Make changes to add threads support
vim PKGBUILD
should look something like
...
--with-xsl=shared \
--with-zlib \
--enable-maintainer-zts
...
Make the new packages
makepkg -s
Install the packages you removed
pacman -U \
php-5.5.6-1-x86_64.pkg.tar.xz \
php-apache-5.5.6-1-x86_64.pkg.tar.xz \
php-mcrypt-5.5.6-1-x86_64.pkg.tar.xz \
php-pear-5.5.6-1-x86_64.pkg.tar.xz \
php-pgsql-5.5.6-1-x86_64.pkg.tar.xz \
php-tidy-5.5.6-1-x86_64.pkg.tar.xz
Install pthreads
pecl install pthreads
Install the 'apcu' package for APC support
cd ../../php-apcu/trunk
makepkg -si
Test pthreads using this code, should get you started:
<?php
class Data extends Stackable
{
//private $name;
public function __construct($_name) {
// if you set any variable, workers will get the variable, so do not set any variable
// $this->name = $_name;
echo __FILE__.'-'.__LINE__.'<br/>'.chr(10);
}
public function run(){
echo __FILE__.'-'.__LINE__.'<br/>'.chr(10);
}
}
class ReadWorker extends Worker
{
public function __construct(&$_data) {
$this->data = $_data;
}
public function run() {
while(TRUE)
{
if ($arr = $this->data->shift()) // receiving datas
{
echo 'Received data:'.print_r($arr,1).chr(10);
} else {
usleep(50000);
}
}
}
}
class WriteWorker extends Worker
{
public function __construct(&$_data) {
$this->data = $_data;
}
public function run() {
while(1)
{
$this->data[] = array(time(),rand()); // write data
usleep(rand(50000, 1000000));
}
}
}
$data = new Data('');
$reader = new ReadWorker($data);
$writer = new WriteWorker($data);
$reader->start();
$writer->start();THE END!
