Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure
@Richard I think, briefly, something like that was implemented. However, it was reverted soon after because it changed the default behavior of configure. This was discovered to be a problem after people realized that, if -a is not specified, APXS will not only skip writing the LoadModule line, but for some inexplicable reason it will also strip the existing LoadModule line if it's already there. I'm guessing that's probably what you're remembering. This RFC differs in that the default behavior of configure will remain unchanged. @Lester Generally, this is a problem that surfaces in manual PHP builds. You're correct in that the packaged repos tend to handle all that stuff for you anyway. However, these repos are rarely updated (I think CentOS and Ubuntu are both still stuck on 5.1), so it's often necessary to build PHP manually if you want to take advantage of the latest features. In these cases, being able to isolate the PHP configuration tends to make the most sense, hence why this new option switch is necessary IMHO. --Kris On Mon, Feb 27, 2012 at 8:59 AM, Richard Lynch c...@l-i-e.com wrote: On Fri, February 24, 2012 6:14 pm, Kris Craig wrote: No, it happens and it's even clearly documented in APXS.

To me this means that the feature adds complexity without current value. The open questions about Apache 1.3 don't belong in the RFC. Document your decisions about what is and isn't going to be supported by the enhancement so that voters know exactly what they are voting on. If you proceed with the RFC, consider overloading the current syntax with the standard optional comma separator: –with-apxs2=enabled,/path/to/apxs # or disabled,/path/to/apxs Also, choose a good time to begin voting, e.g. after 5.4 is released.

Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure
Yeah since we pretty much rely on APXS to do the httpd.conf stuff, we're really limited in terms of what we can do. That is, unless we want to start manually doing this in the configure script in lieu of APXS, though I'm not sure that would be worth the trouble and the overhead. LoadModule clashes still happen in the current releases. I haven't tested it on 5.5-dev but it definitely exists on 5.3.x. I have yet to test it on 5.4 but I'm not aware of any changes there that would've affected this. So this is an existing problem, though admittedly it's really just more of an unnecessary annoyance. If you're doing QA work or something else that involves frequent PHP rebuilds and you have your PHP configuration in a separate .conf file (as is good practice anyway), this tends to become quite irritating. And since APXS already has the solution built-in, it seems kinda silly not to make use of it. The open question of course won't be in the RFC when voting begins. However, I have yet to hear from one single person on that question. I'll make an arbitrary decision on that if nobody cares, but I want to give everyone an opportunity to weigh-in on that question. At very least, could somebody tell me if we're still supporting Apache 1.3.x or not? If we are, any idea if/when we're planning on phasing that out? I'd feel a lot better if I at least knew where we stood on that. I'll look into the comma separation suggestion and see if that'll work. Mainly I just want to make sure we're not breaking any existing functionality; i.e. I want people to be able to not specify this at all and still get the same behavior they did before this change. --Kris On Fri, Feb 24, 2012 at 3:34 PM, Christopher Jones christopher.jo...@oracle.com wrote: On 02/24/2012 02:38 PM, Kris Craig wrote: Thanks for the input!

Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure
No, it happens and it's even clearly documented in APXS. Basically, if you specify the -a option in APXS, it overwrites your httpd.conf (or apache.conf or whatever it is on your system) and adds the LoadModule line to it. In PHP's configure script, you'll notice that -a is always specified; there's no option to use APXS without it. As a result, make install will always overwrite your LoadModule entry in httpd.conf if APXS is enabled. The problem occurs when you have LoadModule in an included .conf file already; APXS does not have the ability to detect that. Therefore, a duplicate LoadModule entry is added to httpd.conf by APXS, and thus the clash occurs. This behavior has been reproduced numerous times. I think the RFC is pretty clear on how this works. Nobody else has expressed confusion thus far. I could clarify further but I'm not sure how; it's pretty straight-forward, really. I'm not sure what may have been happening in your case or if perhaps you misunderstood what this RFC is about. Either way, I would recommend you create a fresh Linux-based build environment, build Apache 2.2 and PHP 5.3.10 yourself (i.e. stay away from yum/apt-get), then attempt to generate an APXS-enabled Makefile using PHP's configure script that does not activate APXS with the -a option. It might also be a good idea for you to check-out the APXS documentation (I included a link to it on the RFC). Those steps should enable you to reproduce this. =) --Kris On Fri, Feb 24, 2012 at 4:02 PM, Christopher Jones christopher.jo...@oracle.com wrote: On 02/24/2012 03:54 PM, Kris Craig wrote: LoadModule clashes still happen in the current releases.

Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure
Oh ok, I think I see where you're getting confused. This problem occurs when your LoadModule statement is in a *separate* .conf file; i.e. using the Include statement. APXS cannot detect this and just sticks a LoadModule into the main .conf file. This is what causes the duplication. It's a very common issue as many people (myself included) prefer to keep their PHP configurations separate. --Kris On Fri, Feb 24, 2012 at 4:42 PM, Christopher Jones christopher.jo...@oracle.com wrote: On 02/24/2012 04:14 PM, Kris Craig wrote: No, it happens and it's even clearly documented in APXS.

Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure
@Johannes Agreed. That was one of the reasons I decided to make the existing behavior (i.e. -a) the default. I haven't independently confirmed that issue in APXS but I have heard it mentioned before; I'll test it myself when I get home just to make sure, since the APXS docs are a bit vague on this. Either way, I think so long as our documentation is clear and the existing behavior is default then it shouldn't pose a problem. --Kris 2012/2/20 Johannes Schlüter johan...@schlueters.de Hi, On Mon, 2012-02-20 at 17:02 -0800, Kris Craig wrote: Opening discussion on RFC pertaining to adding a new option to the configure script with regard to how/whether APXS touches the httpd.conf file.
