Re: Done before?

Same here.
I like XHTML.
It's only slightly less horrible than HTML but yeah... shame that XHTML 1.1
has to be served as application/xml, which no version of IE supports :-(
The only XHTML compliant templating/content management system I have
seen is in Java, it's called Java/XMLC, by enhydra.

Hey, Java is cool. It's just that Perl is Way Better :-)
Before I proceed, are there ANY content management/templating systems that
RELY EXCLUSIVELY on TAG ATTRIBUTE (name=value) nomenclature
to allow interaction between template and perl code?
I wrote a module inspired by the Zope Page Template TAL specification [1]
which uses only tag attributes. It can process XML (using XML::Parser) or
HTML (using HTML::TreeBuilder), and outputs either XML or more
specifically XHTML (for tags like input or br which __HAVE__ to be self
closing)...
The module is called Petal (for Perl TAL). It's on CPAN. [2]. It's still
under
development but it's getting very workable now. There is also a Petal
mailing
list [3].
Are there any that don't follow that model, but are 100% XHTML compliant?
Petal uses extra attributes which you can declare a namespace for. For
example,
let's say that you have the following object.
package Node;
sub parent();
sub children();
sub id();
sub title();
Here is a fragment of Petal code that could operate on the following
structure:
h1 petal:content=here/titleCurrent node title/h1
div petal:condition=true:here/children
pList of child nodes:/p
ul
li id=someDummyID
petal:repeat=child here/children
petal:content=encode:here/title
petal:attributes=id string:${here/id}-nodeDummy node Title for
WYSIWYG editors/li
/li
/ul
/div
You can send this to HTML tidy, or use frontpage and dreamweaver, and
attributes will be
preserved. There are many more features to Petal, but it's all documented as
POD and there
are many use cases on the mailing list archives.

[Q] Exception Handling
Hi all,
I usually receive just the digest mails and don't take part in the
discussions, so I'm maybe new to the list. I studied mod_perl guide,
grepped through my archives, visited search.cpan and even asked some
perlmonks, but couldn't find an answer to my problem. Here it is:
I have a content handler, which calls another module for translating
perl sources into valid html code. As this results in various nested
eval blocks, and each of these blocks will possibly die or warn for some
reason, I like to have a stacktrace through the eval{}s being reported
to the client in error cases, something like:
A mystic Perl error in some context
at /var/www/html/test/t3.html line 8
at /var/www/html/test/t2.html line 2
at /var/www/html/test/t1.html line 889
(Please believe me: Carp is for special reasons *not* the answer)
If I understand the mod_perl guide (pp. 70-73) right, the solution will
be in an Exception class, overriding the CORE::die function. Well, but
if my translation module implemented that class, and Exception.pm
finally CORE::die()s, what about the content handler? Let's say the
translator dies with a well formed stacktrace, how can I get this to
the browser? Is it possible to override CORE::die twice? In the inner
loop, the translating module, and again by the content handler? Would
Exporter-export_to_level be a way out? Or the Exception class being
used by the translator, while the content handler simply uses CGI::Carp
qw(fatals_to_browser) ? (If the content handler used the Exception
class, this one would have to interfere with values it cannot know.) Or
is there actually no problem at all, and I've just lost my way?
I hope I could make clear what I mean, my English must read awful for
native readers. Anyway, if you got a clue, or just an address where I
could dig a little deeper...
Thanx a lot in advance
regards
Martin

$r-print() with slow clients and stop button
Hi, I've created a meta-search that prints out status messages to the browser as it receives responses from the servers it is searching by setting $|=1 and using $r-print. It runs as a mod_perl handler. I'm running apache 1.3.24 and mod_perl 1.26 on Linux. I'm finding that my web app has slowed down radically since I started doing this. I've tracked it down to the $r-print statements. I suspect that each statement is waiting for acknowledgement from the client before it will continue execution. Sometimes children are tied up for 2 minutes! I suspect these may be where the client has dropped its dialup connection and $r-print is waiting for acknowledgement of a packet. Has anyone else had this problem? I've set httpd.conf's Timeout setting to 5 seconds as a temporary fix. As I understand it, this will affect the amount of time perl waits before triggering soft_timeout or hard_timeout when doing $r-print operations? I'd like to somehow send data to the client and have execution continue until the end of a time critical section, after which it will wait for acknowledgement of all data that was sent and if that is not received within X seconds, kill the connection and return OK. The only way I can think of doing this is to get the client socket connection, temporarily change it to non blocking, do a send on it, finish the piece of code, and then change it back to non-blocking once I've confirmed the data was sent correctly. I'm afraid (very afraid) that this will break apache or mod_perl somehow. Does this sound like a workable solution? My C isn't too hot, so I'll be coding the entire thing in Perl and running it as part of the handler. Is there a better or easier way to do this? thanks, ~mark http://www.workzoo.com/ [EMAIL PROTECTED]

RE: Done before?
Thanks Perrin.
I probably skipped your Templating guide because I'd already used more than
half of them myself :)
I'm probably going to skip HTML_Tree because it's tree-ish and not
events-ish. I'm currently an events-ish type person. Probably because I
imagine it's faster.
I'm also going to skip HTML::Seamstress since it has perl inside attrib
values, which is not compliant
From the Seamstress man page
td class=worker id=$s-_text($s-{iterator}-{name})
That's no good.
I'll look closer into Petal...

Of course. HTML_Tree
(http://homepage.mac.com/pauljlucas/software/html_tree/) works this way
and is mentioned in my templating guide
(http://perl.apache.org/docs/tutorials/tmpl/comparison/comparison.html).

RE: large projects in mod_perl
The resources that were pointed out were great! For large web apps MVC is great, especially when combined with XML and XSLT. It is certainly not a panacea as someone stated in an earlier post. Mod_perl can function as an application server. I don't know a whole lot about this, but I know it can be done. I am currently looking into playing around with mod_perl in an application server setting. Cache::Cache seems promising for keeping objects around. MVC type code offers a good separation of work flow from business logic and view logic. Not sure what transaction management packages are out there now. I am not sure of what app server products/projects are out there now for Perl (maybe some were mentioned earlier). The building blocks are definitely there. I am sure someone has assembled, or is assembling, them to serve as a turn key app server.

What about using sax filtering and custom tag libs to accomplish your transformations? If you don't like XSLT (I can see how that is possible :) ) and you are comfortable with events, you can put together a really good transformation layer.

First of all: $r-user doesn't work because you haven't gotten the Apache

my $r = Apache-request;
before your call to $r-user.
Why you aren't getting anything in $ENV{REMOTE_USER} I do not know. It

odd authetication situation
I have a modperl handler that sets a cookie and does a redirect if the
cookie was not present. The redirected page eventually loads the same page
again. In addition, this page is called from a protected portion of the
site that requires Basic Auth.
When the redirect calls the mod_perl routine the second or some
subsequent times, $r-connection-user and $ENV{REMOTE_USER} are both
empty or non-existent yet the page does not appear to fail the
authentication request and executes and returns html.
The failure is repeatable though not consistently so, maybe 70% or more.
I'm scratching my head on this one. Any ideas??

Re: odd authetication situation
Maybe you can try to add specifically:
$r-connection-user('who_the_user_is') before the cookie access control
returns OK in the module. Note that some of the cookie authentication
modules are based on access-only control so $r-connection-user() can
return a value in late phases only if one assigns it at the first place.

hmm... let me see if I understand what you are saying
It is necessary to specify $r-connection-user('current-known-user');
before I send OK so that on the next contact by the browser to the web
server $r-connection-user will have the correct value???
Is this because of keep-alives and using the same child process??
I would think that the client would send the token for each connection.
then what about the Cookie?? It appears that gets lost sometimes,
but not as often as the authentication token. This fuzzy behavior makes
redirects where cookies and tokens are expected very dicey...

Point of clarification...
The authentication I'm writing about is BASIC AUTHENTICATION. apache takes
care of all of that. It appears as though the client is not sending it,
but I don't know why ... and if not, how it manages to pass the
authentication portion of the apache request loop.
the example I'm using does the following:
.htaccess
AuthType Basic
AuthName MagicName
AuthUserFile
/home/web/public_html/cgi/private/user.access
require valid-user
scriptA.plx -redirect to scriptB.plx
scriptB.plx -redirect to scriptA.plx CONDITIONALLY
if the CONDITION is met, the redirect is not done
i.e. cookie present + user present
what happens.. scriptA always has ENV{REMOTE_USER} and
$r-connection-user valid
scriptB rarely has them both valid
either script can set the same cookie if it is not present.
The cookie is always present for scriptA and usually but not always
present for scriptB
WHY???

please finish reading the section explaining how to get the backtrace.
You've got only the first frame. You need to execute 'bt' or 'where' to get
it all.
Are you going to say this is a PHP bug? :-)
But how come if I only activate PHP module, it works fine.
Something affects a datastructure which PHP uses and segfaults in it. But
get first the whole backtrace.

Re: odd authetication situation
The client only sends basic auth credentials when requested. So if you have an authorization handler that might validate a cookie and return OK before basic auth credentials are requested of the client, then you will need to set $r-user from that handler for it to be accessible later on down the chain.

Re: [mp-1.99_05] HPUX 11 w/gcc 3.2(b) -Ae missing ... predicateerror

Hi,
I noticed in 'lib/Apache/Build.pm' that the -Ae option was being added
even if the compiler was gcc. This options causes an error something
like the following:
... missing '(' after predicate ... error
In the code below (lib/Apache/Build.pm) I removed the '#' comment from
in front of:
return if $Config{cc} eq 'gcc'; #XXX?
to work around this problem and things compiled just fine.
thanks. i've made the change in cvs.

If the following is inserted in httpd.conf: Perl /Perl I get, reasonbly enough: Syntax error on line 961 of D:/Apache2/conf/httpd.conf: Perl sections not yet implemented in modperl-2.0 Tough, but fair. But why should the following: IfDefine fubar Perl /Perl /IfDefine give me the totally unreasonable: Syntax error on line 960 of D:/think4/Apache2/conf/httpd.conf: Expected /Perl but saw /Perl not sure, but likely an apache issue. anyhow, in the cvs version of modperl-2.0, pluggable Perl sections have been implemented (see posting to the dev list). somebody just needs to implement a default handler to actually convert the Perl code to apache config.

99.99% sure this is largefiles related, as somebody else mentioned.
you need to make sure php was compiled with the same flags as httpd.
that is, if you built php before mod_perl, you need to recompile php so it
uses the largefile flags. or.. rebuilt modperl/httpd with Makefile.PL
