hooks
I've just been playing with the all the different hooks, just to see how
it all hangs together.
eg
sub hook_connect {
my $self = shift;
$self-log( LOGDEBUG, '*CONNECT' );
return DECLINED;
}
I am unable to get the connect, pre_request or body_data hooks to
fire. They are similar to the above, (perhaps with OK instead of
declined) or just a straight forward die.
I also notice that response sent goes via my code, but when I use
the browser back button, Response sent is on the console, but
nothing from my hook.
Anyone any ideas?
John

Re: AxKit2 Wiki
Jorg, I have added frist pages to the AxKit2 wiki located at: http://trac.axkit.org/axkit2/wiki Well done! Feel free to add to my effort, explaining your own experiences or trying to understand my explanations. I have a few questions/points... I think it's been mentioned before either on list or in the docs about where stuff should be installed. I don't think (as apposed to the wiki) that the modules etc should be under a per site directory structure. That makes upgrading more tedious and time consuming. The modules should be installed in the usual perl module area, eg under site_perl. The plugins should be under the AxKit2 directory in a directory called plugins. That makes installing with a make install possible. I like the ideas about SSL using stunnel or squid. Do they work under windows though? I was under the impression that SSL could be handled via apache and requests passed on the Ax2. Is this possible? John - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
SSL
Lo all, I was wondering how easy it would be to add SSL to Ax2. The reason being I need an SSL webserver for another project and I'm unsure as to how difficult it would be to take the code and add in SSL myself. It wouldn't be serving web pages, just messages.

Static files and hook_xml_response
Lo, I'm still having static files, .js, .jpg etc go through hook_xml_response. I have a test in there that returns DECLINED for such files, but it's a bit of a kludge. Perhaps it should be possible to do it via the config file? I was told it did this some time back but the latest svn (back then) didn't seem to do it.

My personal favourite has been what you describe (and what I present as third scheme), plus a way to have two (or more) plugin directories: global (core) plugins, private plugins and maybe custom system-wide plugins. Well that's two of us, is that nearly a consensus! But I don't have any experience with that kind of setup. Instead, I now know how nicely multiple private copies of AxKit2 work. I like them, as I tend to suffer from update-breakage rather often. heh I like the ideas about SSL using stunnel or squid. Do they work under windows though? I think so, yes.

I just have to content myself with not writing crappy sql :) A page typically takes 100th of a second to generate on our production server, which isn't too shabby. Given the above (I presume it's correct) the ways around it are 1) Have a separate DBI daemon that processes requests and uses Danga. ie A db request is palmed off to the DBI server and the DBI server gives Ax2 a kick when the data has been retrieved. I believe Danga sockets have this capability. 2) Have Ax2 forkable. qpsmtpd which seems very similar to this has a qpsmtpd-forkserver option.

I've just installed IO::AIO and Danga::Socket on the slack 2.6.14 kernel and both installed ok but I still get with poll() using the code above. More importantly, does it mean that ax2 will run like a pig on the RH with poll() only? To check if AIO works I've just tried to install IO::AIO - if it fails then it's not available. Doh!

I've had a look at the namespace options and there doesn't seem to
be a way to set the default NS for nodes I create, which could make
the code very ugly to look at, it being littered with an NS text.
Having said that, I could make it a constant.
The reason for the does it matter was that in my case, I find all the
elements for a NS do a get first child and then a get next sibling
and then add a node. I have no idea if the get child and sibling are
NS aware, but as all the nodes are from the xslt they have the same
NS anyway. The node I add didn't have a NS but still worked in the
browser. I've now changed the add node to use the NS.

Spot on!
If that's the case you should create elements with createElementNS
('http://www.w3.org/1999/xhtml', 'div').
Does it matter if I don't?
which'll get body elements in the right namespace. Or if you're
confident enough, match in any namespace with either
$doc-getElementsByTagNameNS('http://www.w3.org/1999/xhtml', 'body');
Fixed it! Thanks!

hook_xmlresponse question
I thought I'd modify the xml, just before it gets sent to the browser.
$out-input seems to contain the xml that's sent to the browser.
(It has all the correct fields in there when I run $out-input-toFile())
Now to mess about with the xml I have put a dummy div as the last
child of the body
So, in theory, I can get the body tag and run lastChild on it. ie
my $root = $out-input-getElementsByTagName('body')-
get_node(1);
But it doesn't return anything. his makes the server fall over with a
plugin error, $root being undefined.
If I change 'body' with 'div' (there are plenty of divs) it returns a value.
I am using getElementsByTagName elsewhere in my code and it
works perfectly; but this is against a $dom that I build, not one that
has been through xslt.
Any ideas?

POST params problem
A new one this time. If I have a form that doesn't send any parameters, the server hangs. I found this out through having a form that only had checkboxes on it, none of which were checked. There is a workaround, hide a text field on the form. Of course, that won't be used by people wanting to mount a DOS attack.

Is there any chance that get_node(0) returns something? Have you
tried to dump the NodeList you get to see if it contains anything?
Well, the docs say that the node list starts from 1 not 0. But I have
tried it :) The above code is used elsewhere, even the get_node(1)
for a single unique node in my DOM. This works.
It's the getelementsbytagname that's failing.
When I try to get the body tag the node list is empty.
Bizarrely enough, when I try with the div tag, of which there are
several, the nodelist contains only the one Element object.

A number of implementations are a bit fuzzy on what they match on for non- namespaced methods. The NS variant may work better, and failing that you can match on //*:body. It is a long shot in so far as I have no idea how to do that! The getelementsbytagname does work on the dom I create, it doesn't seem to work on the dom that is returned after it has gone through the stylesheet transforms (3 of them).

it will break my Axkit 1 set up. (If it makes a difference.)

Re: parse_post_param problem
Jörg, http://domain.dom:8000/foo/?fire=hot Is the above a valid url? the / before the ? looks wrong. It's a perfectly valid URL. If you don't want to upgrade, that's the easiest way to go. Oh I don't mind upgrading. The problem I have with the dodgy looking url is that it would break my app if the user edited it. Which I don't want. What I've done to get round my problem is to have a fixup hook. If the request is a POST, I save the params to cache. If it's a get and we aren't about to redirect, i save the params to the client param api. Is this a valid way to do it? (the best way?) I strongly suggest to upgrade, or if you don't want to, to use URLs ending with / where needed. Both variants are much better than a caching solution. Ok, I'll dig out the svn stuff and d/l it now.

I would imagine it gets processed straight away,but I have no idea how, what's the mechanism? threads? Or are multiple server daemons set up and the request passed to them, like apache does? btw, how does one download axkit2? I have a new app to write using ajax etc in about 3 weeks and would like to use it if poss. Assuming the current paradigm for axkit2 is whats going to be decided upon of course.

It's blocked until you re-enter the event loop. Obviously that's bad,
so I'll be investigating ways you can do long running stuff. It'll be
some API along the lines of:
$self-do_slow(sub { ... });
return CONTINUATION;
And when that's done (bearing in mind it'll be in a separate process
so you'll need to arrange for a way for data to be returned) the
continuation will pick up again at the next plugin in the chain.
Leaving plugins to one side for the moment...
In my particular scenario:
The server sits there listening for a request. This request
has to go to a db, retrieve lots of data, generate the xml etc
and eventually pass back html. Let's say that the retrieval of data
takes about 5 mins.
If 100 users put in a request at the same time, the server blocks to
service to first user, how does it service the other users without
forking or passing them on to other daemons ot threads?
(I have never used threads and have little idea about them)
Would I be correct in thinking that the mod_perlish speed you
can achieve is due to the one instance of perl that is running the
httpd and app?
So rather than the perl httpd running my perl app, in effect my perl
app has an httpd embedded in it?
(don't worry about the gritty details - I've done this sort of thing
for qpsmtpd already so it's just a SMOP and documenting it)
SMOP?
btw, how does one download axkit2?
At the moment it's SVN only. I can put a snapshot up somewhere if you
like.
Thank you, but I've sussed it out. Well the d/l at least. The up and
running may take some time, I'm a perl Makefile.PL wallah :)

(I have never used threads and have little idea about them) So rather than answer this, I'll throw the question back to you - how do you currently cope with a system that expects 100 concurrent users requesting pages that take 5 minutes to generate? The only similar thing I have is a daemon that sits and blocks on a pipe waiting for requests from a process that monitors directories. So I don't lose requests (assuming I could, not sure if it's possible) as soon as I get a request I fork and let the child handle the request without waiting for it and the parent goes back to listening on the pipe. When there are a lot of requests it slows the system down somewhat :) I wrote it about 3 years ago when learnin perl so I am more than happy to explore better methods than perlIO teaches. I presume the way to go would be to have the Danga stuff handle the request in a listener and have it pass on the request to 1 of N other daemons, like apache does now. Probably.

Slow response time
Lo all, I have a page that is generated from data in a db. The users are complaining that it takes from 30s to 60s to load the page. Now I have put logging into apache and from the start of the request to the end (of my code) takes about 14s. Which means the bottleneck is either in AxKit or a net one. How can I log the start and finish time of the AxKit pipeline? I have come up with turning the trace on and looking at the timestamps on the intermediate files, but that isn't ideal. I'd rather it went to the apache log. There is only the one transform the xml goes through. Any ideas?

redirecting
AxKit + SAWA. Lo all, Apologies for the vague subject but I'm not sure how to phrase it. Here's what I want to happen, hopefully someone can give me a clue... I have a page with a url of http://some_document. On this page is a link http://processed_document. When the user selects the link I go to a db and do some processing and return the same page, at most one field may have changed. This is all well and good. However, if the user selects an other link and then presses the browsers back button they get http://process_document which does the db processing again, which is not what I want. In short I want a user on http://some_document to select a link somewhere else and for that link to come up in the browser as http://some_document. Is this doable via Axkit, SAWA or should I be looking at Apache? I have access to the Apache::Request object if that helps...
