I would need to see more output ("sudo port -d install php5") to be sure, but I believe php5 is not compatible with apache2's +workermpm variant. I think this is the same problem as #16596 and  this mailing list post. Please confirm whether using apache2's default +preforkmpm variant instead fixes the problem.

[ryandesign@…]

I can now confirm the problem, which only exists when apache2 is compiled with the preforkmpm variant and php5 is compiled with both the apache2 and fastcgi variants. Using either the apache2 or the fastcgi variants by themselves compiles fine, but together:

To build the php fastcgi binary when the php apache2 module has already been built, I just issue "make" again, which I assume fails in this case because the apache2 module was built with Zend Thread Safety ("zts") while the fastcgi binary is wanting to be built without it ("non-zts"). I could fix that by using "make clean" before building fastcgi, but it still leaves the problem that you would be installing different php parts which are not compatible with one another. In particular, all the php modules you'd want to install separately would only work for one or the other (either the apache2 module or the fastcgi binary) but not both because they would have different extensions directories. And I'm not sure how the php cli would react either.

My current thought is that I should prevent the installation of the php apache module if apache has not been compiled with its default preforkmpm variant.

I did not test what happens when using apache2's third mpm variant, eventmpm.

I'm marking #16596 as a duplicate of this one because although it came first, this one is clearer and gets right to the point.

[ryandesign@…]

I also edited my prior comment to fix my mixup between preforkmpm and workermpm, sorry.

[ryandesign@…]

See also #20527.

[ryandesign@…]

Has duplicates #21573, #21574, #21575. These are a little different: php5 modules compile but don't work if apache2 was installed with +workermpm. So the problem is not just limited to combining the +apache2 and +fastcgi variants of php5; even just using +apache2 you will have problems with modules. So we really should prevent installation of php5 +apache2 unless apache2 was installed with +preforkmpm.

[james.applemac@…]

So, at this time, apache2 with workermpm cannot work with all php5-* packages in Macport 1.8 ? Am I right?

[ryandesign@…]

That seems to be correct. At least, the ones you tested don't seem to work.

The  #1 FAQ on the PHP installation page is "Why shouldn't I use Apache2 with a threaded MPM in a production environment?" so I don't feel too badly about my plan to prevent this from being possible at all. Granted most MacPorts users are probably running a development server, not a production server, but still, why do you need a threaded web server on your development machine?

• r58589: php5 +apache2 now prevents installation if apache2 is not installed with +preforkmpm. Still need to update php5-devel, php52, and php4 with this change.

[ryandesign@…]

• r58830: updated php5-devel with this change

[ryandesign@…]

• r58833: updated php52 with this change

[ryandesign@…]

• r58844: updated php4 with this change.
