eA "vs" ZendFramework: hangs when php.ini(session.save_hanlder = eaccelerator)

hi bart,

fyi, there's a first bit of feedback @ Zend Framework list:

http://www.zend.com/lists/fw-general/200606/msg00326.html

suspecting something "odd" happening with eA.

any news/progress on this?

any interest in addressing it?

at this stage, any sites that use zend's framework simply have to have eA removed ...

But it's only when using the eaccelerator session handler? It's broken, you need to serialize object your self before putting them in eA.

I installed ZF and tried running some demos and unittests and I didn't run in any problem. I also enabled the eA session handler and that didn't change the results either. Could you provide me with a script using the ZF that reproduces these errors?

per request, here's a simple (relatively, in zend-framework-land ...) scenario that reproduces the error as reported.

then, nav to:

displays in browser:

and the rest of the non-eA'd site works perfectly.


if, however, i ENABLE eA:

php.ini:

...
---	eaccelerator.enable="0"
+++	eaccelerator.enable="1"
...
======================================================================

then, nav to:

fails, resulting in a ~30-sec time lag, then display of a BLANK browser page, and, in logs ...

this is 100% reproducible on several boxes, admittedly similarly configured.

a similarly-architected site in CakePHP framework w/ eA enabled is without problem.

a similarly-architected site in Symfony framework w/ eA enabled shows different, problematic behavior, but with:
  eaccelerator.filter="!*/symfony_sites/*/config/*  !*/symfony_sites/*/lib/symfony/*"
seems to 'cure' ...

with latest branch (r259), this is still an issue for both zend & symfony sites.

note, per latest fixes of 5.2-compatibility, for symfony:

--- eaccelerator.filter="!*/symfony_sites/*/config/* !*/symfony_sites/*/lib/symfony/*" +++ eaccelerator.filter=""

This tests are done with the current trunk and php 5.2!
