[OFF] strace

replacing a directory specific legacy CGI
Good morning, gang.
As we migrate to mod_perl, we have one major CGI that is scattered all
over the site. It is directory local and reads config files to adjust
its output. Currently we have one copy in cgi-bin and quite literally
hundreds of symlinks to it from all over the site.
We want to rewrite this in modperl, but I was concerned about the
memory usage of cacheing each local copy. If we put all the pertinent
code into a single module and just make all the local versions call a
processing method, won't the actual working code still be retained in
the module namespace? Since the interpreter is embedded in the server,
that should mean that all the little cached versions are just something
like "sub handler { Module-method; }", right? It just has to compile
and store the hook?
Is that worth worrying about, or am I misinterpreting?
Many thanks, and happy holidays. =o)

Using MHonArc inside of mod_perl
I am trying to get the MHonArc package to work in conjunction with an in house module. When MHonArc (http://www.mhonarc.org) is run and told to process a single file instead of a directoy full of files, it sends the output to STDOUT which inside of mod_perl in this case is the browser. I am using the process_input() function as outlined in the MHonArc mailing list archives. I need to save the output to a variable. It was suggested by Earl Hood (author of MHonArc) that I tie a string to a filehandle and then dup the filehandle to STDOUT. This sounds great, but I am unsure where to place the code that will allow for this or how this needs to be done with mod_perl. (I read perltie and perlopentut, but it didn't light any bulbs). I got some results, but none that produced the desired results. The closest was getting the output to be directed to the resulting HTML page, but not the variable. I saw a email from 97 in the mod_perl archives that discussed untie *STDOUT and then retying it back to Apache after the section of code was complete, but it showed STDOUT being linked to a file open, how could I assign that to a tied string then a filehandle as suggested by Earl Hood? Is anything like this bulit into mod_perl or another module at this time? http:[EMAIL PROTECTED] The process_input function is running under mod_perl. If any other information is needed please let me know. I have a horribly ugly hack working currently, but it prevents MHonArc from running in a normal manner (i.e. processing mailinglists) Aaron Johnson - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If you mena you rewrite to mod_proxy, then mod_proxy does not fill
headers{in} it simply ships what it gets from the remote server with the
content and ships that. You would need to hack mod_proxy for it parse
the headers and provide them to you in the normal request_rec structures.

Actually, something is _adding_ headers and I want it to stop doing it.
It may not be mod_proxy, perhaps it is mod_rewrite. I really don't know.

RE: Problem with Apache::DBI under mod_perl!!
I had some similar problem before. It was caused by the "PerlFreshRestart

Subject: Problem with Apache::DBI under mod_perl!!
Hi all,
I have installed on the my machine the following modules:
apache 1.3.12-2
perl-5.00503-10
mod_perl 1.21-10
DBI 1.14
Apache::DBI 0.87
For enable the mod_perl module, I added the below code in the
configuration file of apache ("httpd.conf"):
# If the perl module is installed, this will be enabled.
IfModule mod_perl.c
PerlFreshRestart On
Alias /perl-bin/ /home/httpd/perl-bin/
Location /perl-bin
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
Options +ExecCGI
/Location
/IfModule
For load the Apache::DBI module, I also added this line in the
"httpd.conf" file:
PerlRequire /etc/httpd/conf/startup.pl
Inside of "startup.pl" file, I added the following code:
#!/usr/bin/perl
use strict;
# Extend @INC if needed
use lib qw(/dir/foo /dir/bar);
# Make sure we are in a sane environment.
$ENV{MOD_PERL} or die "not running under mod_perl!";
# For things in the "/perl-bin" URL
use Apache::Registry;
# Load Perl modules of your choice here
# This code is interpreted *once* when the server starts
use Apache::DBI ();
$Apache::DBI::DEBUG = 2;
$Apache::AuthDBI::DEBUG = 2;
use DBI ();
# Tell me more about warnings
use Carp ();
$SIG{__WARN__} = \Carp::cluck;
# Load CGI.pm and call its compile() method to precompile
# (but not to import) its autoloaded methods.
use CGI ();
CGI-compile(':all');
#Initialize the database connections for each child
Apache::DBI-connect_on_init
("dbi:Oracle:ora8", "travel", "travel",
{
PrintError = 1, # Warn() on errors
RaiseError = 0, # Don't die on error
AutoCommit = 1, # Commit executes immediately
}
);
But, when I try loading a HTML page of WWW server, the server refuse my
request. I think that the problem is in the WWW server that don't load
their child process because to the Apache::DBI to be with some problem.
During the installation of all the modules didn't have any problem. The
apache start correctly, but when I try stoping them, I get a error
message that the process failed.
Locking the configuration files, can anyone tell me what is happening?
Any help will very appreciated.

Does mod_perl have anything to do with KeepAlive?
Hi All - I'm hoping for some enlightenment about how KeepAlive is implemented in Apache and whether KeepAlive even comes into play when front-end and back-end mod_perl servers communicate with each other via HTTP. Suppose front-end server A is handling user requests. In the process of handling a front-end request, suppose I use LWP or equivalent to make a HTTP request from A to a back-end server B to get some data that is needed. Assuming all the right headers are set for KeepAlive to work (content length, etc.), can the connection between A and B even take advantage of KeepAlive for the next time A makes the same request to B? One problem is that I'm not sure what processes would actually be "keeping" the ends of the "kept alive" connections. At each end, would it be the parent httpd process, or the individual httpd child process that made/answered the request? I'm thinking that if A had to fork a CGI that in turn talked to B, the kept-alive connection would be lost as soon as the CGI process on A died (socket timeouts notwithstanding). But what if the request from A to B is made from within a mod_perl module, or within an Apache::Registry script? Along the same line of thought (assuming this has made any sense so far), what happens when you throw ProxyPass/ProxyPassReverse into the mix? What (if anything) can be done to take advantage of KeepAlive then? Larry Leszczynski [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

In Singapore and Malaysia, Java seems to have had so much government backing that a lot of IT professionals are into Java but not into Perl.

How do I redirect STDOUT to a string WAS Using MHonArc inside of mod_perl
After one response and my own re-read of my first email, it appears that I have asked far too vague a question. The correct question is: How do I redirect STDOUT to a string? A suggestion was to tie a string to a filehandle and dup the filehandle to STDOUT. Is that valid? If it is, how in blue blazes do I do that? I read the perltie docs, the perlopentut and others I just don't see it. I will re-read them and hope my light bulb works. If anyone can point me to another source of information I would be grateful. Are there any modules for such oddness? I am posting to the mod_perl list in case there are any gotchas doing this under mod_perl. I realize it is border line off topic. I have MHonArc doing what I need it to, but it required a butcher knife when all I think I need is a butter knife.

After stripping the connection header, it simply passes the headers it got from the backend server right on along to r-connection via ap_proxy_send_hdr_line (or ap_proxy_send_headers for cached files IIRC). Moreover if your backend server calls ap_send_http_header during its response, it *must* return a Server and Date field unless your request is assbackwards. See the src for ap_basic_http_header in src/main/http_protocol.c. mod_proxy will upgrade assbackwards requests to HTTP/1.0 before passing them along to the backend server, which may explain why the date field shows up in your telnet experiments.

FYI this is not mod_perl related. You'll want the IO::String package. If the perl function you are calling is just printing to the default filehandle (which I'm guessing it does), you should be able to just 'select' the IO::String object: my $str; my $str_fh = IO::String-new($str); my $old_fh = select($str_fh); # call MHonArc or whatever here print_stuff() # reset default fh to previous value select($old_fh) if defined $old_fh; --Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

On 27 Nov 2000, Joe Schaefer wrote: mod_proxy will upgrade assbackwards requests to HTTP/1.0 before passing them along to the backend server, which may explain why the date field shows up in your telnet experiments. Why not post the full output of your telnet sessions so we can see what is really going on? Actually, this totally explains the problem, as did Sander's previous post. I'm attempting to use Apache as a non-HTTP server (sending ICY headers for streaming MP3 instead). So yes, its an assbackwards request and its upgrading it. Which is annoying. It would be nice if this were configurable in mod_proxy.c. Maybe I will have to look at the code. But I'm afraid of C. -dave /*== www.urth.org We await the New Sun ==*/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Using MHonArc inside of mod_perl
Perhaps you just need to use Apache::Filter? If not, you can cannibalize some of the code in Apache::Filter, it re-ties STDOUT. [EMAIL PROTECTED] (Aaron Johnson) wrote: I am trying to get the MHonArc package to work in conjunction with an in house module. When MHonArc (http://www.mhonarc.org) is run and told to process a single file instead of a directoy full of files, it sends the output to STDOUT which inside of mod_perl in this case is the browser. I am using the process_input() function as outlined in the MHonArc mailing list archives. I need to save the output to a variable. It was suggested by Earl Hood (author of MHonArc) that I tie a string to a filehandle and then dup the filehandle to STDOUT. This sounds great, but I am unsure where to place the code that will allow for this or how this needs to be done with mod_perl. (I read perltie and perlopentut, but it didn't light any bulbs). I got some results, but none that produced the desired results. The closest was getting the output to be directed to the resulting HTML page, but not the variable. ------ Ken Williams Last Bastion of Euclidity [EMAIL PROTECTED]The Math Forum - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [OT] Re: Proxy adding headers
On Mon, 27 Nov 2000, Sander van Zoest wrote: Ah, are you trying to send ICY headers or something? mod_proxy only knows of HTTP and sends the appropriate status itself rather then what it gets from the remote server. This will also require some hacks in mod_proxy to make it aware of the protocol you are trying to proxy. Well, I guess C is easier than I thought. I got it working via a new config directive for mod_proxy, ProxyAddHeaders. By default its true and this means that mod_proxy will add minimal headers for wack responses from the proxy server (like HTTP 0.9 or ICY or whatever). However, if you turn it off it will _not_ add these headers. There is a bug in the current state of the code in that if the caching code is called, it will add a Date header if none exists. I'm currently working around this by turning off caching. I'm going to see if there is interest in the Apache core team in having this submitted as a patch. Is so, I'll work around the remaining bug. In the meantime, if anybody on this list is interested I can send you my current patch, which is against 1.3.12. Its not many lines so porting it to a different Apache version should be trivial. -dave /*== www.urth.org We await the New Sun ==*/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Proxy adding headers
Dave's company could also *pay* someone to do what he wants. It would probably take about a day of someone at Covalent (probably less) to whip something up to stop doing the headers (and they would probably be able to feed the change back into the mod_proxy part of the Apache CVS directly so others would benefit).

Help! Objects are disappearing!
Here's the situation: I have a master module, which 'use's other objects in same hierarchy. It creates the objects and assings references of them to the local variables. Everything compiles, even works. That main module receives requests and directs to one of the created objects, passing CGI object and request object... But on second run it disappears. All function calls fail because it says it can't call function on undef object. Help?

Great, as soon as I can find a company willing to fund my work on a personal MP3 server I'll be all set ;) Actually, I already did most of the patch and I sent a message to the new-httpd list to discuss the possibility of making this a part of a future release. Of course, if someone at Covalent wants to help that's great too. And for the record, it took a lot less than a day. About 1.5-2 hours, I'd say. -dave /*== www.urth.org We await the New Sun ==*/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
