IPC:Open3 does not work under mod_perl/1.25, perl5.6.0?
My program, which worked under mod_perl/1.23 and perl5.500502 does not
work anymore:
I fork a program with Open3, send it some input and catch its output.
The output is OK, but the program does not get the input:
...
my $cgi_in = Apache::File-new;
my $cgi_out = Apache::File-new;
my $cgi_error = Apache::File-new;
...
my $child = open3 ($cgi_in, $cgi_out, $cgi_error, $filename);
...
if ($post) {
my $len = $r-header_in ('Content-length');
while ($len) {
my $content;
my $size = min ($len, 4096);
$r-read ($content, $size);
$r-log-debug (content: $content);
print $cgi_in $content; # this statement does not work
$len -= $size;
}
}
close ($cgi_in);

IPC:Open3 works on my system, and I can print to files from my mod_perl

[OT] mod_perl 2 question...
I was just looking at Doug's overview of mod_perl 2, and was specifically intrigued by the PerlInterpLifetime directive, which got me sorta excited. It would appear to me, based on that, that by setting PerlInterpretLifetime connection, you could have a good chance at getting good persistant "session"s with any HTTP/1.1 client, with no more than plain ol' global variables. Moreso, you can see which is the first request easily just by checking defined($someglobalvariable) - or so it would appear... Can any of the mod_perl 2 people provide some feedbak on this, as I'm sure you guys have looked at this much deeper than I have.

Well, I'm not a mod_perl 2 person, but I can say that PerlInterpScope (it's been renamed) merely lets you control whether interpreter threads are allocated per HTTP request/subrequest/handler call/connection, not associate an interp with a client. The 'connection' option (I think) looks like it's mostly for more session oriented protocols, the FM (modperl_2.0.pod) mentions ftp. If you wanted to muck about in C or with your own protocol handler, you could take some session ID (cookie, URL, say, just not the client's IP address) and direct it to a particular thread, but... You probably don't want intepreters devoted to individual clients whether they be in threads or in processes. Waste of good memory, that. It might help in rare circumstances with keepalives (pure conjecture here), but keepalives don't guarantee that the client will only make one connection. Without keepalives on, most popular browsers make multiple connections to the server and can keep several connections busy at once. That's still technically possible with keepalives, though I don't know if any browsers try to open multiple kept-alive connections intentionally (though they can if a server has more than one IP host name). Closer to what you're thinking of are the 'solar' variables Doug mentions wistfully. But unless you back the in-memory store to a disk or something, you lose on server shutdown, which takes you back to conventional session management techniques, although it does look like you could share some fewer number of database connections or open filehandles between your threads to do this using Doug's wrappers around Apache's memory pools. - Barrie

apache::registry + use strict curiosity
I found something a bit curious that I was wondering if someone could
explain. I have the following apache::registry script I called test.reg:
#!/usr/bin/perl
use strict;
if($test){
# do stuff
}
print qq|HTTP/1.1 200 OK\r\n|;
print HELLO WORLD\n\n;
I ran my server in single-user mode (httpd -X) and requested the page
which causes an internal server error because I didn't declare '$test'.
I next commented out the three conditional lines:
#if($test){
# do stuff
#}
Then requested the page a second time, which executed just fine. I
uncommented those three lines and requested the page a third time, which
strangely enough actually works. Registry stats pages to see if they
change and recompiles pages I believe. So I am wondering why isn't an
exception raised on the third request about not declaring '$test'? Did
the first request put '$test' in the symbol table?

single server mode problem
Hello, we are trying to do some debugging in single server mode, but we have problems. We tried running the httpd daemon from the command line: > .../apache/bin/httpd -X or configuring the http.conf like this: MinSpareServers 1 MaxSpareServers 0 StartServers 1 MaxClients 1 and starting the server normally with > .../apache/bin/apachectl start In both cases we have the same problem: The CGI runs up to a certain point and then stops, like waiting for something (we can follow this with tail -f .../error_log), the browser waits for more data to come (that will never come). But if we press STOP on the browser, the CGI resumes/continues to run and goes to the end. It seems that this happens only if the CGI is doing a considerable amount of work, if it ends quickly we don't have problems. It also looks like it always stops on a print statement, maybe there is some problem flushing the buffer. Any idea about what is wrong here? Thanks, Giacomo
