creating an instance of Apache2::RequestRec
hello folks, has anyone tried to create an instance of Apache2::RequestRec outside apache ? I'm not an xs expert, but if i understand correctly Apache2::RequestRec basically wraps the request_rec from apache2, therefore creating one should be initializing a struct with some params calling sv_setref_pv to get a blessed reference ? cheers, bharanee
Re: creating an instance of Apache2::RequestRec
It would work for the purpose of testing, mainly simulating a request without running apache like Apache::Test does currently. But as you say, it would mean replicating the C functions. Just wondering if someone has attempted this ?

Re: creating an instance of Apache2::RequestRec
Just following up, this is already mentioned in perldoc Apache2::RequestUtil "It's possible to reuse the HTTP framework features outside the familiar HTTP request cycle. It's possible to write your own full or partial HTTP implementation without needing a running Apache server. You will need the "Apache2::RequestRec" object in order to be able to reuse the rich functionality supplied via this object." I'm not sure if the CommandServer example is relevant since it only works from inside apache2 On 8/31/07, Perrin Harkins <[EMAIL PROTECTED]> wrote: > > On 8/30/07, bharanee rathna <[EMAIL PROTECTED]> wrote: > > has anyone tried to create an instance of Apache2::RequestRec outside > > apache ? > > How could that work?

Re: creating an instance of Apache2::RequestRec
Yep, something like FakeRequest is the easy solution, I guess one could write something similar for apache2. Still, it's intriguing that a standalone HTTP implementation is mentioned in RequestUtil's pod but I cannot find a real implementation example anywhere. -bharanee On 8/31/07, Perrin Harkins <[EMAIL PROTECTED]> wrote: > > On 8/30/07, bharanee rathna <[EMAIL PROTECTED]> wrote: > > It would work for the purpose of testing, mainly simulating a request > > without running apache like Apache::Test does currently. > > Apache::Test does it this way because it's a better way to test.

Hi guys, this is a known issue reported at
http://issues.apache.org/bugzilla/show_bug.cgi?id=38848
and not modperl related.

Re: -X and trapping kill?
yes, but AFAIK -X is a shortcut for -DONE_PROCESS. But then I may be wrong but a quick check now shows me that using -DONE_PROCESS, apache2 ignores SIGINT On 9/18/07, Philippe M.

Re: Problem with RequestRec and Headers
AFAIK Apache::Singleton works for MP2, also it does both per request and per
process singletons.

Re: Problem with RequestRec and Headers
Yep, that's a bug
perldoc Apache2::RequestUtil
# get the global request object (requires PerlOptions +GlobalRequest)
$r = Apache2::RequestUtil->request;
which means u need GlobalRequest in apache config, which I'm not a big fan
of. Better raise a bug in cpan rt for this module and get Tatsuhiko to fix
it. By the looks of it, this hasn't been updated in a while.
personally I don't really see a need for Apache::Singleton::Process unless
there needs to be a module for consistency in Apache:: namespace,
class::singleton does pretty much the same job. If you need a per-request
singleton meanwhile, cookup something quickly of your own that uses apache
pnotes to store the instance

Re: Mod_Perl and MaxRequestsPerChild
Although mod_proxy is a nice module with many features, I would recommend something like pound doing the proxying & load balancing. It's more light and faster, plus you have the added advantage of keeping your webservers in a local network. If you want something with more features lookup squid, but I've had best results with pound using apache2 worker for static content and apache2 prefork for modperl2 apps on different servers.

Maybe someone should write to the author/maintainer and take ownership ? http://rt.cpan.org/Public/Bug/Display.html?id=19775 Easy fix though as noted in the RT ticket. Also I think you should turn on global request, PerlOptions +GlobalRequest otherwise you would not be able to get the request object via Apache2::RequestUtil->request,. Alternatively you can set the request object in your handler initially as Apache2->request($r); - b
