Partial page output when using zend optimizer+

[bitinn]

This is my config:

zend_optimizerplus.enable=1 zend_optimizerplus.memory_consumption=128 zend_optimizerplus.interned_strings_buffer=8 zend_optimizerplus.max_accelerated_files=4000 zend_optimizerplus.revalidate_freq=10 zend_optimizerplus.fast_shutdown=1 zend_optimizerplus.enable_cli=1 zend_optimizerplus.optimization_level=0 zend_optimizerplus.error_log=/var/log/zendop.log

I am using codeigniter as my php framework, once I switch zo+ on, all page output appear to be "cut off" at a certain point (randomly), never finish to the end </html> tag.

the strange thing is that I saw no error in php or zo+ log, and the cut off point isn't linked to a specific variable.

outputing phpinfo() works without problem, I am wondering how should I even start to debug this problem?

[bitinn]

Previously php-fpm logging was not on, with it enabled, I am see this kind of logs every time I visit an affected page:

[13-Mar-2013 00:58:45] WARNING: [pool www] child 6734 exited with code 1 after 176.326628 seconds from start [13-Mar-2013 00:58:45] NOTICE: [pool www] child 6761 started

Without ZO+ it does not produce any of above logs.

Any tip to continue debugging it?

PS: unlike others, I do NOT see segfault error in log, just the child exit/restart

BTW: I am using the latest master, should I be using v7.0.0?

[dstogov]

You should use the latest master v7.0.1-dev. Also be sure that you completely recompile PHP and O+ for for th same PHP build. Which PHP version do you use? Linux? 32 or 64-bit PHP build?

I would say it might be a bug in code optimizaer, but you already switched it off using zend_optimizerplus.optimization_level=0.

You may try to check for possible memory corruptions running single FastCGI sapi instead of FPM.

USE_ZEND_ALLOC=0 valgrind sapi/cgi/php-cgi -b

[bitinn]

Yes I am using the latest source, though I am not sure what you mean by "completely recompile PHP"

My PHP version info:

I posted a bit more info on: http://serverfault.com/questions/487310/using-zend-optimizer-with-php-fpm-nginx

(strange to see no one talking about ZO+ on serverfault/stackoverflow, at least none recently)

[rlerdorf]

Well, only a few people have any experience with this, and you will find those people here, not on serverfault/stackoverflow. But yes, the first suggestion there to try it without Suhosin is a good one. There are no guarantees this will work with Suhosin.

[bitinn]

@rlerdorf you are right, I just thought if PHP 5.5 were to bundle ZO+, they might as well advocate the community to test it first? :)

When I tried to google ZO+, I really don't see many Zend Server admin or PHP developer trying it out, maybe because it's new.

Anyway, will test default PHP later and report back.

[bitinn]

Tried same config with suhosin.simulation = On, still the same issue and logs

PS: Given that quite a few linux distribution does apply suhosin to their default package (in my case Ubuntu), I am not sure how they will go forward with PHP 5.5...

[bitinn]

switch to https://launchpad.net/~ondrej/+archive/php5 for php 5.4 without suhosin, upgraded and re-compile ZO+ using new build and following config:

[zend]
zend_extension=/usr/lib/php5/20100525/ZendOptimizerPlus.so
zend_optimizerplus.enable=1
zend_optimizerplus.optimization_level=0
zend_optimizerplus.error_log=/var/log/zendop.log

Now the site works, BUT, neither phpinfo() nor php -v show ZO+, so I am guessing the module is not loaded for some reason. no error/warning/notice log from php-fpm or ZO+

I run into issue where make test output following:

Build complete.
Don't forget to run 'make test'.

ERROR: Cannot run tests without CLI sapi.

and my php-config --php-sapi return empty, is this the default result for php 5.4? or am I missing something.

ok so I am missing the config for php-cli, added and it output:

$ php -v
Zend Optimizer+ requires Zend Engine API version 220090626.

wait, doesn't ZO+ support 5.4.* already?

[rlerdorf]

Of course it does, but the one you built is for PHP 5.3. 220090626 is the API version for PHP 5.3.

[bitinn]

@rlerdorf thx, after downloading the source and running phpize again, now it appear to load correct. still can't seem to run make test like I did when in PHP 5.3.x though, Any idea what could have caused the ERROR: Cannot run tests without CLI sapi. error after upgrade?

[rlerdorf]

Which configure flags are you using? The CLI sapi is built by default unless you explicitly disable it using --disable-cli or --disable-all

[bitinn]

phpize
./configure
make

I tried it with explicit --with-php-config=/usr/bin/php-config previously, but got same error.

_php-sapis_ were empty in php-config output, is it what might have caused it? I can't seem to find a config value for it

[rlerdorf]

This looks like more of an Ubuntu packaging issue than a PHP/ZO one. The php executable to be used for tests is gotten by calling: php-config --php-binary If that doesn't return a working php, then you can't run the tests. You can fix this manually by editing the Makefile in the ZO directory and near the top you will find a line like:

PHP_EXECUTABLE = /usr/bin/php

Set that to a working php binary and you should be able to run the tests.

[bitinn]

done that and it passes all 3 tests like in 5.3.x. that's some warm feeling :)

thx to @rlerdorf and @dstogov , and I should close this as a confirm on suhosin messing thing up.
