work has started in Centmin Mod 123.09beta01 though not there yet for PHP 7.3.0 alpha 1 Beta Branch - update PHP 7.2+ argon/libsodium routine & prep PHP 7.3 alpha support

seems Zend Opcache error might be related to specific Intel Xeon Gold Skylake cpu's AVX instructions for PHP 7.3.0alpha1

Code (Text):

tried on my Intel Xeon E3-1270v1 Sandy Bridge cpu and seems fine to compile with Zend Opcache but still results in segfault

Segmentation fault

lets see if it's php extension related starting with centmin mod added ones

Code (Text):

php --ini

Segmentation fault

doing to edit and comment out extension load lines for igbinary.ini, mailparse.ini, imagick.ini and redis.ini with semi-colon in front of the line and restart php-fpm

Code (Text):

grep -rn ';extension' /etc/centminmod/php.d
/etc/centminmod/php.d/redis.ini:1:;extension=redis.so
/etc/centminmod/php.d/mailparse.ini:1:;extension=mailparse.so
/etc/centminmod/php.d/igbinary.ini:3:;extension=igbinary.so
/etc/centminmod/php.d/imagick.ini:1:;extension=imagick.so

restart php-fpm

Code (Text):

fpmrestart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

no segfault, so related to one of those commented out extensions not being PHP 7.3.0alpha1 compatible yet

Code (Text):

lets start re-enabling commented out extensions to see which is one that causes segfaults

re-enabled mailparse extension and yup segfault

Code (Text):

cat /etc/centminmod/php.d/mailparse.ini
extension=mailparse.so

Code (Text):

fpmrestart
Gracefully shutting down php-fpm  done
Starting php-fpm /etc/init.d/php-fpm: line 65: 16729 Segmentation fault      $php_fpm_BIN --daemonize $php_opts
 failed

re-enabled redis, igbinary and imagick and no segfaults so problem related to mailparse php extension compatibility with PHP 7.3.0alpha1

 

seems php memcached and memcache extensions showing issues too now on E3-1270v1 server

PHP 7.3 bug list here

 

Updated 123.09beta01 with more updated memcached php extension code for PHP 7.3.0 alpha1 - seems I was using an older memcached php extension branch code !

Updated 123.09beta01 with workaround for PHP 7.3 alpha compilation failures due to CentOS 7 GCC 4.8.5 and CentOS 6 GCC 4.4.7 compilers being too old or a bug in detecting newer cpus support for AVX instructions in newer cpus like Skylake or Broadwell. So workaround is if PHP 7.3 is detected, switch to newer GCC 7.3.1 which is already used for Nginx compiles
