tried just about any trick you can think of to get the value from
$port{$portname} to $Port, but I can't -- if I add to it or substract
from it, it's fine, but if it somehow gets back to the original value,
in any way, it doesn't work again.
Does that give any new ideas as to the source of this issue?
Yes. The source of the issue is that you sent your ErrorLog to
/dev/null. Send it somewhere else where you can read it and you should
find the error in short order.
That's what I do in my configuration file -- I just trimmed it down to
show just the code that matters in the sample that I sent to the list.
Here's the error I get in the error log:
[Wed Jul 19 10:07:14 2000] [crit] (13)Permission denied: make_sock: could not bind to
port 80
It couldn't bind to port 80 because another web server is running
there. This means that it didn't recognize the $Port setting,
although printing $Port from within the config file prints 8010
properly. That's precisely the problem.

Segmentation Fault
Hello all,
I posted this just before everyone got all excited about the ORA conference
and I think it may have been overlooked. I'd really appreciate hearing from
anyone who can give me some clues regarding the back trace.
Cheers,
Greg.
I have recompiled mod_perl/apache with PERL_DEBUG=1
running
gdb httpd
followed by
run httpd -X
produces the following output:
startup.pl is attempting to modify the include path...
startup.pl is attempting to modify the include path...
Program received signal SIGSEGV, segmentation fault
0x807ca20 in perl_handler_ismethod()
(It is interesting that the "...modification..." line appears twice. I added
it (once only!) to the beginning of my startup.pl so that I could see if it
was being found.
It somehow seems to be being found more than I expected! [Ged has pointed
me at something in the guide that has a partial explanation for this...])

If you wanted to do it in "pure" mod_perl (no mod_proxy), write a TransHandler similar to the ones listed in chapter 7 of the Eagle book, pp 368 - 381 (pp 372 - 373, for example, is an anonymoizing proxy, and pp 374 - 381 is an ad-blocking proxy).

Using fork() in programs running under apache
Hi, I have a script that uses a smtp to send a message and this is causing an overload of my server, because the execution time (that would be some milisecs) is delayed by about 5 secs. I thought I could solve this by forking the process, so the user would get a faster answer and the forked process would be more light than the 7MB of apache. Does anyone have any experience in forking processes under apache? I made some tests and it looked ok, but I'm not so sure that this won't cause problems in the future. Thanks. []s Luis

Help! Need strategy for upgrading production system!
Hello, I have a production system (solaris 7) with apache 1.3.6 system with mod_perl.1.19 and mod_ssl.2.3.1 I would like to somehow install the latest apache + mod_perl + mod_ssl + DBI/DBD versions on the production system, BUT without interrupting the current production system. And then, after I have moved over and tested the production web application in the new server, cleanly switch over. In other words, is it possible to install new versions of apache + mod_perl + mod_ssl + DBI/DBD (and all the dependant modules) into a separate directory on the production system -- WITHOUT affecting the older apache production server? How in the world do I cleanly upgrade apache + mod_perl + mod_ssl + DBI/DBD? Thanks, Keith
Re: Help! Need strategy for upgrading production system!
For this sort of thing, I assign a second IP address to the machine, then configure everything to bind to that IP address (making sure the original implementation binds to the first IP address only). For apache and the modules, you can just create separate source directories, and designate a unique target for installation. You might want to make the target match up with the version of Apache. I.e. make the target for the new one "/usr/local/apache1.3.12". As long as the source is also separate from the production source, the modules should slide in without touching anything else. Change the configuration to point at your production document dir and script dirs, or create new document and script dirs if you're ultra paranoid. Test out on the second IP address all you want. While the server will be running on the same machine (and that presents a little bit of risk exposure), it'll be a separate instance with separate files and everything. When it comes time to move to production, shut down the test server. Change the conf file to bind to the primary address. Then, in quick succession, stop the production server and start the new server. Change over (hopefully). The trick is to start using versioned target directories for your stuff. Instead of just cramming it all in /usr/local/bin, set up /usr/local/apache1.3.12/bin etc. doug On Wed, 19 Jul 2000, Keith Kwiatek wrote: Hello, I have a production system (solaris 7) with apache 1.3.6 system with mod_perl.1.19 and mod_ssl.2.3.1 I would like to somehow install the latest apache + mod_perl + mod_ssl + DBI/DBD versions on the production system, BUT without interrupting the current production system.

You would need a lot of memory in this situation. With mod_proxy, apache starts pushing data of to the client as soon as it gets it from the server.

I've never been to an IT conferance like these - and they appear quite popular. Especially the BOF's. I can see why you are having trouble understanding why the expense is worth it if you've never gone. I am considering going to the ApacheCon Europe to see what's said and put a few faces to names and meet a few people. However, I've just seen the prices - I am not saying that everyone should do this for free or not be paid thier travel / hotels, but it seems a little expensive. Three days off work + threeday pass + other expenses + travel = 5% of my income (I am contractor - hence I pay for it all). 795 pounds for early bird special? Translates to about US$1400. That seems pretty reasonable for a 3-day conference. I've seen ones that cost more. Am I being a scruge or is this a fair reflection of the cost of going to an event ? Will there be out-of-Conference events that This is the fair cost and you are being a scruge. There are cheaper conferences around but they are usually grass roots, holed up in a university etc... non-conference-goeres can attend ? Thoughts from anyone ? Yeah, you're being pretty cheap. :) Well, I'm sort of kidding here. But the reality is that a conference offers a lot -- not just knowledge (then just attend a tutorial locally at Sun or someplace) but networking. The coordination of a conference is a huge task. Anyway, most conferences do have a free vendor expo, but I don't think that it's nearly as good as going to a whole conference. If you really want to attend a conference for "free", why don't you contribute back to the community that has been helping you make a living and give a talk? Let's put it this way, conferences are pure and simple a business expense BUT they are also fun. Don't go if it's not fun. Then look at it like this... what do you pay to go on vacation? Surely it's the same basic formula minus the conference fee which by itself is less expensive than getting training the equivalent days at SUN. If you didn't go on vacation because it cost you 5% of your salary... OK then... that's your choice... then I guess I would find it hard to convince you that it's also worth it to go to a conference.

Another interesting thing about this issue: if I assign

tried just about any trick you can think of to get the value from
$port{$portname} to $Port, but I can't -- if I add to it or substract
from it, it's fine, but if it somehow gets back to the original value,
in any way, it doesn't work again.
Does that give any new ideas as to the source of this issue?
Yes. The source of the issue is that you sent your ErrorLog to
/dev/null. Send it somewhere else where you can read it and you should
find the error in short order.
That's what I do in my configuration file -- I just trimmed it down to
show just the code that matters in the sample that I sent to the list.
Here's the error I get in the error log:
[Wed Jul 19 10:07:14 2000] [crit] (13)Permission denied: make_sock: could not bind
to port 80
It couldn't bind to port 80 because another web server is running
there. This means that it didn't recognize the $Port setting,
although printing $Port from within the config file prints 8010
properly. That's precisely the problem.
After fooling with this for several hours I've finally come to the
conclusion that this is probably an Apache "problem".
The quickest way to illustrate it is trying this Perl section...
Perl
my %port = ( zz = 8014 );
warn "PORTHASH: $port\n";
use POSIX ();
my $portname = POSIX::getcwd();
chomp $portname;
warn "PORTNAME1: '$portname'\n";
$portname =~ s:.*/::;
warn "PORTNAME2: '$portname'\n";
$Port = $port{$portname};
warn "PORT: '$Port'\n";
my $ppid = getppid;
warn "PPID: $ppid\n";
/Perl
Now, try running your server as before, but make sure you have access to
the ErrorLog file. You'll notice that several of the warn()'s generate
completely different output in the error_log than they do on your shell
screen.
The first significant difference is that PORTNAME1 points to `/home/zz'
(or wherever you started httpd from) in your shell, while in the
error_log it points to `/'. I'd almost bet money that the conf file is
parsed the first time under your shell, then again after Apache has
disassociated itself, thus showing you seemingly valid output on the
shell.
If you then grep through the Apache source you'll find this in
src/main/http_main.c...
static void detach(void)
{
#if !defined(WIN32) !defined(NETWARE)
int x;
chdir("/");
Bingo!
Now the question is how to pass the proper directory name to mod_perl's
Perl sections. The answer lies subtly tucked away on p. 423 of the
Eagle book. Just add a PerlPassEnv to your conf file...
PerlPassEnv PWD
Then use $ENV{PWD} instead of POSIX::getcwd() and you should be all set.

Re: Filtering HTML files with mod_proxy and mod_perl
Hi Wim, I've created something like this. I've attached the script I used to build mod_proxy and mod_perl, and a short Apache::MyFilter to show how to use this. Note: I've cut down the handler from my version without really testing it, so it may have a couple syntax errors. thanx! But ... I think it doesn't work in my case, because I have to change the HTML-content itself. Or do you get somewhere the plain HTML-Content of the final HTTP-Request? If yes this part is missing in the example! ;) Ciao Alvar -- Alvar C.H. Freude | [EMAIL PROTECTED] Demo: http://www.online-demonstration.org/ | Mach mit!

Re: Filtering HTML files with mod_proxy and mod_perl
Hi, This is what mod_proxy does on its own, no mod_perl needed. including filtering? If you wanted to do it in "pure" mod_perl (no mod_proxy), write a TransHandler similar to the ones listed in chapter 7 of the Eagle book, pp 368 - 381 (pp 372 - 373, for example, is an anonymoizing proxy, and pp 374 - 381 is an ad-blocking proxy). This chapter is available on the web in its entirety at http://www.modperl.com/book/chapters/ch7.html. Pretty simple, all in all. yes, I think this is ECAXTLY this what I an searching for! thanks!

Re: Filtering HTML files with mod_proxy and mod_perl
Hi, If you find a way to do it with Apache::Proxy, let the list know. I am sure it will work with the example given by Darren. If i checked it I think I'll create a small module and can spread it. One of the major reasons I went this route over something like the examples in the mod_perl book, was speed. Downloading big files using the examples book was slow, as apache first gathers the content up into a variable (where you can do your regular expressions or whatever manipulating), then sent it to the browser. You would need a lot of memory in this situation. yes, but if you use a subroutine which handles the incoming chunks, you can pass the file emmediatly.

Re: What's this error?
I have also noted a fair amount of [Wed Jul 19 16:01:58 2000] [notice] child pid 24703 exit signal Segmentation Fault (11) I get this, too, a *LOT*. Err... I'm convinced that our current mod_ssl 2.6.5 is 100% stable and does not produce any segfaults. If you really get segfaults, some other component causes it. Let me guess: You're running PHP or mod_ssl+OpenSSL as a DSO underf Solaris, right? Forgive the "me, too"-ism, here, but this problem just won't seem to go away. I'm running on HP-UX B.10.20 (best the company will spring for) on a PARISC1.1 9000/891. I probably did build DSO, though, and I really don't need it. Hmm think the same prob might apply here? If no, then I've no clue and you have to attach a debugger to find out where it segfaults. Somebody suggest a debugger? I'm feeling pretty ignorant, here, and unfortunately won't have any time to RTFM for a few weeks yet. (~mumblegrumble~) Paul __ Do You Yahoo!? Get Yahoo!
