[Apache::ASP] .htaccess permission denied in examples

Re: logging out
I used Net::LDAP, a pure Perl implementation, against a Novell eDirectory LDAP server.

The authen_ses_key method then recovers the username from the session hash. I created a custom require method to check group membership so I can include something like this in httpd.conf : require LDAPGroup cn=administrators,ou=groups,o=wl I want to extend it to check for container membership too but I don't need that just now.

Re: [Apache::ASP] .htaccess permission denied in examples
Make sure that your asp/eg directory is under your htdocs and that you have "AllowOverride All" configured for that directory in your *.conf files, probably a Directory setting.

Re: [Apache::asp] Secure execution of scripts by users
Andrew Tucker wrote: A simple (well, maybe not exactly) question: is there a way to allow normal users to run their custom ASP scripts without endangering too much system's security (such as apache suexec or php's safe mode, or even cgiwrap..)? Thanks in advance, If the CGI method of running ASP ever finally worked completely, you could try that. The cgi/asp script is the place to start with that in mind. It doesn't process POST input last I left off with it. The other way you can more safely have separate users run Apache::ASP, as with mod_perl in general, is to have per user web servers running on high ports, and have a mod_proxy front end forwarding requests back to each. This will require more RAM admin headaches to host each user, but will give them the benefits of mod_perl ASP! -- Joshua
Re: XForms ASP
Dmitry Beransky wrote:
...
recognizable tokens (as in ''.'form'). Unfortunately, I cannot use XML or
XSLT processing, as you recommend, because the content of the tags often is
HTML. This brings me to another question. Is (would) it possible to do
recursive recursive XML processing (similar to XSLT) with ASP? Here's an
example:
html
head
xform id="formID"
...
/xform
/head
body
...
asp:form id="formID"
First name: asp:input id="firstName"/
Last name: asp:input id="lastName"/
/asp:form
/body
/html
What I need to do is to process the asp:form element, transform the tag
itself into appropriate html and then recursively process its content, so
that I could get to the asp:input tags.
If its HTML you need, you could substitute a call to
HTML::Parser instead with a XMLSub asp:form to
look for the input tags. You could also do this
all at once at the Script_OnFlush event to parse
both the xform and form at runtime.
If you wanted just a XMLSubsMatch approach, you will have
to work backwards, because inner tags are evaluated
first as sub routines. If you need the input data when you
evaluate the asp:form, then you could try using script
globals to capture data for you, like in each input tag
you could set something in $Inputs{$id} = $data and
then reference %Inputs in your asp:form ... that's
pretty backwards, and is a limitation with a pure
XMLSubs approach to a problem like this.
Best of luck, and I am very interested in what you
end up with.

Re: how to check for ssl.
I've got a section of our site where I want to force the user to connect via ssl. Inside of mod_perl, is there a parameter I can grab to see whether the connection is ssl or not? Or a way to get the port number? If there isnt a special reason otherwise, why not just put a redirect in http.conf, eg VirtualHost _default_:80 . Redirect /secure https://www.mysite.com/secure /VirtualHost Then any attempts to access something under http://www.mysite.com/secure will get a redirect to same page but using https.

Re: Feature sets [was Re: Templating System]
I hope that you write the doc is POD :) I suppose I could... I was planning on having a nice checklist of features/systems that would be a pain to do in a fixed width font. An HTML table would make my life MUCH easier there. Is there something in POD that makes tables easier? Write the text in POD, and put the checklist data in with some neutral format. Then we can use a customized pod2html converter on it to generate a pretty table. XML would be a nice way to store the raw data. This might end up being kind of big for an in-line, so we could do something like "=table data_file.xml" and keep it in a separate file. (Or is it better to use "=for html" and put the rest inside that, so that it still passes syntax checks for standard POD?) I believe XML is a way too heavy for docs writing. Why one will want to get a messy source code, when you can get away with a minimalistic POD. Just look at the Guide's source code and look at the generated PDF -- isn't it great? I love POD. And if you want more than POD provides, it takes secs to add the new functionality. Stas, do you have code available for the guide generator? That might come in handy. The guide building code was completely rewritten lately. Now it uses HTML templates (+css) to customize the look and feel, so if you want to roll your own documentation project you don't have to touch the code anymore. The html2ps translator is bundled in distribution, so there is no installation overhead, just grab the package from CPAN: cpan install mod_perl_guide If there will be enough interest, I'll release the package as a standalone in the future. As for POD, I've already extended the POD in POD2HTML (which was buggy anyway). For example, I've added new directives for embedding images, linking to files and more... I don't afraid to extend the POD since I can easily convert all my extended pod files back into the standard POD format. So if you want a syntax for tables, this should be easy to add, like: =table args =tr args =td args ... =/td =/tr =/table Drew, if this all sounds like too much trouble for the first draft and you already started in HTML, I'd say just finish that up and we'll distill it into POD later.

Re: Package Lexicals and PerlModule
mgraham ([EMAIL PROTECTED]) said something to this effect:
With the above I expect to be able to call the following in some
handler:
Foo::load_var()
...and $PACKAGE_LEXICAL should still be 'wubba'.
...Except that by calling Foo:load_var() you are setting $PACKAGE_LEXICAL
to undef (by passing in an empty list via ()), rather than retrieving it.
You should do something like:
package Foo;
{ # Block scope this stuff just to ensure that no other subroutine besides
# var can modify $PACKAGE_LEXICAL.
my $PACKAGE_LEXICAL;
sub var {
return
(@_)
? $PACKAGE_LEXICAL = shift
: $PACKAGE_LEXICAL;
}
}
# More of package Foo here...
1;
This will set $PACKAGE_LEXICAL if you pass something in, and return it, or
just return it otherwise. Each child will have its own $PACKAGE_LEXICAL.

libapreq (Apache::Request) unhappiness

Well, Joe and David's version, I've just discovered, fails to correctly deal with large POSTs that are not file uploads. In particular, I just wrote a lengthy (3 hours!) email in my webmail system, and when it got to the recipiant only the first and last bits were there :-( I've replicated this behaviour with a number of large POSTs, and the problem always occurs (under Linux 2.2+latest stable mod_perl and Apache).

That's not how things went. AFAIK, Jim's group scrapped the old multipart_buffer.c code and started fresh. The patch I submitted just modified the existing code in order to get the memory usage under control. David just pointed out that GNU's 'memmem' function, which is used in my patch (but not in Jim's) is not available many OS's, so he kindly submitted his own. Well, Joe and David's version, I've just discovered, fails to correctly deal with large POSTs that are not file uploads. In particular, I just wrote a lengthy (3 hours!) email in my webmail system, and when it got to the recipiant only the first and last bits were there :-( I'd be glad to look into it. Could you send the html form that's causing trouble, and the post data as well? Also, are you using David's memmem patch? I've replicated this behaviour with a number of large POSTs, and the problem always occurs (under Linux 2.2+latest stable mod_perl and Apache). The good news is that Jim's version doesn't have this problem. Are there any volunteers to fix Joe and David's more efficient version? (Sorry, I'm no C guru...) If Jim's version is working for you, great. As for 'efficiency', I don't know how the memory usage compares between Jim's patch and mine, but I can say that I spent one weekend making the patch.

NAME
Apache::Dispatch - call PerlHandlers with the ease of CGI scripts
SYNOPSIS
httpd.conf:
PerlModule Apache::Dispatch
PerlModule Bar
Location /Foo
SetHandler perl-script
PerlHandler Apache::Dispatch
DispatchPrefix Bar
DispatchExtras Pre Post Error
/Location
DESCRIPTION
Apache::Dispatch translates $r-uri into a class and method and runs
it as a PerlHandler. Basically, this allows you to call PerlHandlers
as you would CGI scripts - directly from the browser - without having
to load your httpd.conf with a slurry of Location tags.
=head1 EXAMPLE
in httpd.conf
PerlModule Apache::Dispatch
PerlModule Bar
Location /Foo
SetHandler perl-script
PerlHandler Apache::Dispatch
DispatchPrefix Bar
/Location
in browser:
http://localhost/Foo/baz
the results are the same as if your httpd.conf looked like:
Location /Foo
SetHandler perl-script
PerlHandler Bar::dispatch_baz
/Location
but with the additional security of protecting the class name from
the browser and keeping the method name from being called directly.
Because any class under the Bar:: hierarchy can be called, one
Location directive is be able to handle all the methods of Bar,
Bar::Baz, etc...
CONFIGURATION DIRECTIVES
DispatchPrefix
The base class to be substituted for the $r-location part of the
uri. Applies on a per-location basis only.
DispatchExtras
A list of extra processing to enable per-request. They may be
applied on a per-server or per-location basis. If the main
handler is not a valid method call, the request is declined prior
to the execution of any of the extra methods.
Pre - eval()s Foo-pre_dispatch() prior to dispatching the uri
uri. The $@ of the eval is not checked in any way.
Post - eval()s Foo-post_dispatch() prior to dispatching the
uri. The $@ of the eval is not checked.
Error - If the main handler returns other than OK then
Foo-error_dispatch() is called and return status of it
is returned instead. Without this feature, the return
status of your handler is returned.
SPECIAL CODING GUIDELINES
Apache::Dispatch uses object oriented calls behind the scenes. This
means that you either need to account for your handler to be called
as a method handler, such as
sub dispatch_bar {
my $class = shift; # your class
my $r = shift;
}
or get the Apache request object yourself via
sub dispatch_bar {
my $r = Apache-request;
}
This also has the interesting side effect which would allow you to
define, say, a base error_dispatch() method in Foo which is then
inherited by Foo::Bar, but overriden in Foo::Bar::Baz.
NOTES
In addition to the special methods pre_dispatch(), post_dispatch(),
and error_dispatch(), if you define dispatch_index() it will be called
by /Foo or /Foo/. /Foo/index is always directly callable, but /Foo
will only translate to /Foo/index at the highest level - that is,
when just the location is specified. Meaning /Foo/Baz/index will call
Bar::Baz-dispatch_index, but /Foo/Baz will try to call Bar-Baz().
There is no require()ing or use()ing of the packages or methods prior
to their use as a PerlHandler. This means that if you try to dispatch
a method without a PerlModule directive or use() entry in your
startup.pl you probably will not meet with much success. This adds a
bit of security and reminds us we should be pre-loading that code in
the parent process anyway...
If the uri can be dispatched but contains anything other than
[a-zA-Z0-9_/-] Apache::Dispatch declines to handle the request.
Like everything in perl, the package names are case sensitive.
Verbose debugging is enabled by setting $Apache::Dispatch::DEBUG=1.
Very verbose debugging is enabled at 2. To turn off all debug
information set your apache LogLevel directive above info level.
This is alpha software, and as such has not been tested on multiple
platforms or environments for security, stability or other concerns.
It requires PERL_DIRECTIVE_HANDLERS=1, PERL_METHOD_HANDLERS=1,
PERL_LOG_API=1, PERL_HANDLER=1, and maybe other hooks to function
properly.

No known bugs or unexpected features at this time...

...Except that by calling Foo:load_var() you are setting

Well, actually, I was checking to see if it was set first:
sub load_var {
my $param = shift;
$PACKAGE_LEXICAL = $param if $param;
}
Your example does essentially the same thing, but is interesting
because it puts the sub and the lexical variable in a nested block
scope, and as you say:
Each child will have its own $PACKAGE_LEXICAL.
That's a neat trick! However, for my purposes, I don't want each
child to have a separate $PACKAGE_LEXICAL. I want to set the variable
with the parent process (actually from setup.pl) and I want children
to be able to call the sub without any parameters. And I want the
variable to be visible to subs in the same package, but not to code
outside the package. It's kind of like a class variable without
objects. Maybe it would be clearer with two subs:
package Foo;
my $PACKAGE_LEXICAL;
sub set_var {
$PACKAGE_LEXICAL = shift;
}
sub do_stuff {
# do something with $PACKAGE_LEXICAL;
}
I want to be able to call Foo::set_var('wubba') from startup.pl, and
then call Foo::do_stuff() from some child process.
The weird thing is, this works as I expect when I put "PerlModule Foo"
in httpd.conf, but not when I put "use Foo;" in startup.pl.
Does everybody else use PerlModule to pull in their modules, or
startup.pl?

Re: error from modper ??
Try restarting apache. I get problems like this too, where sometimes some stuff will happen, and sometimes it won't. The only way I know of is to restart apache. If anyone else knows a better way, I would like to know! I know that mod_perl compiles a copy of your script, and keeps it in memory. But it does it per httpd process. So, if you don't restart your web server to clear the memory, and copy of the wrong script is still in memory. However, if you happen to get an httpd process that has never seen that script before, it will compile your updated one, and keep it in memory. I believe that this is how it works, I would apprectiate any corrections, and any more info on the subject!!

One extra question: Can I turn on mod_perl SSI and have normal SSI calls at the same time? In other words, can I have one page (file.pshtml maybe) parsed by perl-extended SSI and another (file.shtml) be parsed by normal (without perl, mod_ssi?) SSI? I'm not sure (I think probably not), but you can get the same effect if you use Apache::SSI for some pages and regular mod_ssi for the others. It also depends on what you mean by "mod_perl SSI". If Rob is talking about Ken's Apache::SSI handler, that's one thing, but compiling PERL_SSI=1 to add #perl extentions to "regular" mod_include is another. Setting up Apache::SSI to handle some files and mod_include to handle others is not a problem. But is it possible to selectively allow #perl in only some mod_include files?

Template caches
I briefly asked about this in a previous post, but I wanted to follow up. I'm curious but not very experienced, so any comments would be welcome... I have a home-built template cache system that is limited by size. I was logging failed cache hits (and thus reloading a template from disk) and was surprised at how often it was happening. So... I like the ideas of converting templates to subroutines and then caching those on disk. I really like the idea of then bringing those into the server and compiling them and keeping a cache of those compiled subroutines in memory. Having the templates in the cache seems like a big win, so one would want to keep as many templates in the cache as possible. This in-memory cache must be limited and controlled to some degree I would expect, especially since they cannot be shared across mod_perl server children to save memory. Now, let say for once we do have a limited amount of memory, and we have a very large number of templates, and the templates are very large and mostly plain old text. In other words, the compiled templates are basically big print statements with only a small part being variable interpolation. Since the templates are large, I could imagine a situation where the compiled template cache is thrashed, or at least the templates don't live in the cache very long. As someone who used to program on machines with 8K, all that plain old text in non-shared memory bugs me a bit. Maybe this is already being done, but I was wondering if separating the templates into text and code segments might allow more templates (template code, that is) to be placed in the running server's cache at any given time would make any sense. It would be slower to generate a page, of course, but that might be offset by a greater cache hit-rate and less reloading compiling of templates. And the text segments could be shared by all server processes by using IPC::Sharable -- or maybe it would be fast enough to let the OS file system buffer the commonly used templates, or use a database to load the text segments. So my question is only would such a system make sense, or is memory so inexpensive and templates normally so small that there wouldn't be any benefit? Bill Moseley mailto:[EMAIL PROTECTED]

Since the templates are large, I could imagine a situation where the compiled template cache is thrashed, or at least the templates don't live in the cache very long. Mason tries to address this by checking for the amount of text in a template and turning large plain text sections into subroutine calls that read the text from disk. I think this is a good solution that other systems would do well to emulate. (Of course you can adjust what counts as "a large amount of text" according to your available free RAM.) Mason also has a very nice size-limiting scheme for the cache, using an least-frequently-used + aging algorithm for its removal policy. And the text segments could be shared by all server processes by using IPC::Sharable -- or maybe it would be fast enough to let the OS file system buffer the commonly used templates, or use a database to load the text segments. Just let the filesystem do it. It's much simpler and it lets the OS handle things that the OS is good at. - Perrin

Since the templates are large, I could imagine a situation where the compiled template cache is thrashed, or at least the templates don't live in the cache very long. There are two situations I can realistically see this being a problem: 1. You haven't bought enough memory for your server considering your data set and other issues. 2. You are an ISP running one of these template systems, with multiple virtual hosts. I actually don't have any solutions to this, and its exactly the reason I want to bring Mason and AxKit together, because AxKit sure does use a lot of memory. The only real benefit is where you've got static files in the cache. You can effectively stop the server (clearing the cache) and restart it and deliver from the cache. Provided nothing changes the templates will never be loaded again. -- Matt/ Fastnet Software Ltd.

Re: ignore header_only()?
Thanks for the speedy response. You've now emboldened me to ask my second question: sometimes I see people not calling send_http_header() and yet their HTML still comes through. Does mod_perl sometimes automatically call this for you? Nat

Does mod_perl sometimes automatically call this for you? Yep, its a configurable option. http://perl.apache.org/guide/config.html: [..] PerlSendHeader On PerlSendHeader On tells the server to send an HTTP header to the browser on every script invocation. You will want to turn this off for nph (non-parsed-headers) scripts. The PerlSendHeader On setting invokes ap_send_http_header() after parsing your script headers. It is only meant for CGI emulation, and to send the HTTP header it's always better either to use $q-header from the CGI.pm module or to use $r-send_http_header using the Apache Perl API. [..] Ajit
Re: how to check for ssl.
For some reason (probably my error), $r-get_server_port() always returns 80 although my mod_perl backend only listen to 8080 and 8443 (I use Listen directives). I'm using (sockaddr_in($r-connection-local_addr))[0] to get the port instead. Though it works, I must load one more module (Socket), which I would like to avoid if possible...

Problem with mod_perl and CGI script with Netscape
Greetings, A couple of days ago, I installed mod_perl to speed up a CGI program I use to generate HTML pages for my web site http://www.mostgraveconcern.com . The CGI script is a perl script that ran fine before mod_perl, and now runs fine with Internet Explorer, but Netscape Navigator insists on downloading the page instead of executing it on the server and rendering the output. The CGI script is called with an HTML anchor tag such as: A HREF="qengine.cgi?frames=OFFmode=TOPICterms=Government"Government/A My httpd.conf file has the entry: Directory /usr/local/www/html/quotes Files ~ "\.cgi$" Options ExecCGI Includes SetHandler perl-script PerlHandler Apache::Registry PerlSendHeader Off /Files AllowOverride None Options Indexes ExecCGI Includes Order allow,deny Allow from all /Directory I embeded the Files section inside the Directory because I have other cgi scripts in other directories that are compiled programs. When I try 'PerlSendHeader On', Internet Explorer chokes on SSI tags after '!--#exec cgi=" ', displaying the name of the SSI script, e.g., 'css.cgi"', while Netscape simply prints out the document (HTML tags and all) without rendering it. I searched the mailing list archives, but couldn't find anything about this. I also printed out a lot of mod_perl documentation, but I've got about 800 pages to go through... If someone has run into this before, I'd really appreciate hearing from you!
