Featured CentOS 7.x How to help test .08 CentOS 7 Betas with Github code ?

i suspect it's to with 32bit os.. i'll add a check for it and enable clang only for 64bit

other work came up heh

 

yeah i implemented clang method for 64bit only for now make clang alternative to gcc compiler 64bit only · centminmod/centminmod@750214f · GitHub

also number of minor fixes and checks here and there Commits · centminmod/centminmod · GitHub

what's install time like ? /root/centminlogs last line of install log and other logs have the times

 

thanks @Steve Tozer for all your testing and contribution

Nice.. need to see how i can improve the PHP side times too

 

Testing out .08 beta03's new clang support for PHP compilations via centmin.sh variable CLANG_PHP='y'. It currently defaults to disabled CLANG_PHP='n' in centmin.sh so need to set to 'y' to enable it. Looks like Clang worked fine with CLANG_PHP='y' when i recompiled PHP 5.4.41 via centmin.sh menu option 5.

ccache 3.2.2 version also working nicely with caching for recompiles, speed up is ~49% faster !

Menu Logs /root/centminlogs/

All centmin.sh menu options have a saved log of what happened at /root/centminlogs/

PHP Install/Reinstall Times

Initial first time PHP 5.4.41 install time during initial Centmin Mod .08 beta03 install took 142.842 seconds (without Clang enabled CLANG_PHP='n')

Code:

tail -1 /root/centminlogs/centminmod_phpinstalltime_100615-131800.log
Total PHP First Time Install Time: 142.842168192 seconds

First recompile of PHP 5.4.41 via centmin.sh menu option 5 done in 182.046 seconds as ccache's cache has yet to be populated and bit slower as ccache has initial overhead which the first time PHP install above didn't. (with Clang enabled CLANG_PHP='y')

Code:

tail -1 /root/centminlogs/centminmod_1.2.3-eva2000.08_100615-180344_php_upgrade.log
Total PHP Upgrade Time: 182.046121141 seconds

On recompile of PHP 5.4.41 with populated ccache cache, much faster at 92.203 seconds. (with Clang enabled CLANG_PHP='y')

Code:

tail -1 /root/centminlogs/centminmod_1.2.3-eva2000.08_100615-180749_php_upgrade.log
Total PHP Upgrade Time: 92.202542684 seconds

PHP 5.4 to 5.6 Clang Compile Tests

Next is to test PHP 5.4.41 to 5.6.9 upgrade via centmin.sh menu option 5 with Zend Opcache enabled and with Clang enabled CLANG_PHP='y'.

Upgrading major PHP versions i.e. 5.4 to 5.5 or 5.6 or 7.0 will usually take longer as all custom additional PHP extensions added by Centmin Mod like igbinary, imagick, apc cache/xcache or zend opcache or memcache/memcached and geoip/mongodb are recompiled ONLY if major PHP version updates are detected. If recompiling within same PHP branch i.e. 5.4.x or 5.5.x or 5.6.x, then those PHP extensions do not get recompiled.

Code:

This will increase your upgrade duration time wise.
Check the change log centminmod.com/changelog.html
to see if any Nginx or PHP related new additions
which require checking YUM prequisites are met.
If no new additions made, you can skip the
YUM install check to speed up upgrade time.

Detected PHP 5.6 branch.
You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if you web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

PHP 5.6.9 Recompile Without Clang Compiler

Now to test recompiling existing PHP 5.6.9 via centmin.sh menu option 5 but without Clang enabled CLANG_PHP='n' in centmin.sh to see how long it takes to recompile PHP. Seems for PHP at least, it could be that Clang disabled is better approach with CLANG_PHP='n' as it's a bit faster for ccache backed recompiles

Initial recompile without Clang enabled CLANG_PHP='n' and switching back from Clang to GCC took 254.05 seconds

Code:

tail -1 /root/centminlogs/centminmod_1.2.3-eva2000.08_100615-184714_php_upgrade.log
Total PHP Upgrade Time: 254.047374844 seconds

2nd recompile without Clang enabled CLANG_PHP='n' but with benefits of ccache took 98.623 seconds

Code:

tail -1 /root/centminlogs/centminmod_1.2.3-eva2000.08_100615-185207_php_upgrade.log
Total PHP Upgrade Time: 98.623154021 seconds

 

Yup seems that way biggest gain in speed for Nginx ~120s saved. LibreSSL with Clang saves ~20s so not much. Have yet to test a fresh install with CLANG_PHP='y' yet though maybe faster for initial install ?

 

Just a reminder for @RoldanLT and folks wanting to customise their centmin.sh options, you can override and keep persistent config changes in at ${CONFIGSCANBASE}/custom_config.inc which defaults to /etc/centminmod/custom_config.inc as outlined at CentOS 7.x - How to help test .08 CentOS 7 Betas with Github code ? | Page 22

 

Another reminder as there's alot of updates to .08 beta03 lately, make sure you have latest code on your server before testing. First post in this thread has outline for updating the code or use git method here Upgrade - Working with git command line for updating Centmin Mod local copies | Centmin Mod Community

Also subscribe and watch for Centmin Mod code updates outlined at Watch / subscribe to Centmin Mod Github Updates | Centmin Mod Community

 

Another bug fix for @RoldanLT issue outlined at Beta Branch - Centmin Mod .08 beta3 + clang compiler ngx_pagespeed psol | Centmin Mod Community

Found the root cause of the problems a bug when centmin.sh has ORESTY_LUANGINX='n' set causes a bug on nginx recompiles. Fixed it with commit to .08 beta03 fix ORESTY_LUANGINX='n' bug on nginx recompiles · centminmod/centminmod@d1eb46a · GitHub

 

doh forgot about that hehe

yeah it's much quicker with clang vs gcc compiler
