Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
Scott, I've been using this Aolserver 3.0 + PHP 4.0.6 for over a year with no problem -- this is new (mis)behavior. In what I'm trying to setup now, the PHP version is the same, but I'm trying to use new versions of Aolserver (3.4.2) and RedHat (7.2, old server has 6.2). I cannot think of any way that Aolserver is causing this problem for PHP, though. At 06:59 PM 11/26/2001 -0600, you wrote: Hi Sean, Is this something you can fix on your own? It's possible that the PHP module for AOLserver is doing this (i.e. it's building a path without checking for relative paths); I'm not sure as I've never used the module or PHP. /s.

Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
I hate to say it, but drop back to 3.0 and test on RH 7.2. If it breaks, then there's something different in the combo between AOLserver and RedHat 7.2. If it works, then upgrade to AOLserver 3.1 and test, then 3.2 and test etc. until you get to 3.4.2, also on RedHat 7.2. Let's find out which upgrade breaks it. When it breaks, get a backtrace with GDB, then look at the sources where it breaks and see what's changed between the code that broke and the version before it. Frankly, I'm surprised that a bad path would cause a segfault, which leads me to believe that some var or pointer isn't being initialized before use. /s.

Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
Ok, then it sounds like an interaction problem between AOLserver and RedHat 7.2 (or more likely the PHP module and 7.2). Can you post the backtrace? /s.

Danny, what do you mean, install a second instance of
AOLserver and
ACS?
With what you're trying to do, you certainly want to run two
separate
AOLserver processes, one for each of your ACS websites.
This is
exactly equivalent to what you would do if you wanted to run
a
Development and Production copy of one website on the same
box. All
you need to do is edit your nsd.tcl file correctly, and run
two
AOLserver processes. This is not any kind of pretty heavy
load to
put on the machine, people do it that way all the time. In
fact, it
is the easiest and probably best way, if you have the two
free IP
addresses to use.
You probably want to use the same nsd.tcl for both
AOLservers, so in
your nsd.tcl, you'd have something like this:
set ip_address(dev) {192.168.100.100}
set ip_address(prod) {192.168.100.101}
set server_name(dev) mysite-dev
set server_name(prod) mysite
# Decide which server we are running:
set ini_file [ns_info config] ;# Full path to this config
file.
set ini_dir [file dir $ini_file]
# This checks the full pathname of the AOLserver ini file,
so it had
# better be located beneath directories called e.g.,
mysite-dev,
# mysite-stging, or mysite:
if { [regexp {[-]dev/} $ini_file] } {
set which dev
} else {
set which prod
}
ns_section ns/server/$server_name($which)/module/nssock
ns_param timeout 120
ns_param Address $ip_address($which)
ns_param Hostname $hostname($which)
ns_param Port $port($which)
If you are starting your two AOLservers from inittab, then
you'll want
two lines something like this in your /etc/inittab :
nsdv:234:respawn:/web/aol3/bin/nsd-oracle -i -t
/web/mysite-1/nsd/nsd.tcl -u nsadmin -g web
nspr:234:respawn:/web/aol3/bin/nsd-oracle -i -t
/web/mysite-2/nsd/nsd.tcl -u nsadmin -g web
If you want to use something more sophisticated to start
AOLserver,
like DJB's daemontools, there are other mthods. See e.g.:

[AOLSERVER] [ aolserver-Support Requests-486126 ] How to debug inside ADP?
Support Requests item #486126, was opened at 2001-11-27 11:30 You can respond by visiting: http://sourceforge.net/tracker/?func=detailatid=203152aid=486126group_id=3152 Category: Configuration: Other Group: aolserver3_2 Status: Open Resolution: None Priority: 5 Submitted By: Danny Lieberman (dannyl50) Assigned to: Nobody/Anonymous (nobody) Summary: How to debug inside ADP? Initial Comment: Hi I am running aolserver 3.2 with open acs 3/posgres 7.1 For debugging, we open 2 windows: browser in window 1 and tail -f servername.log in window 2 we are doing heavy SQL/tcl development and the errors get swallowed up in the servername.log file. isnt there a way JUST to see the errors and not all the GET commands? In another installation i had with aolserver 3.1 and acs 3.5/oracle - we had TWO (2) logs - servername.log and servername-error.log thx danny -- You can respond by visiting: http://sourceforge.net/tracker/?func=detailatid=203152aid=486126group_id=3152
Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
Okay. Could you provide the source for the entire virtual_file_ex()
function from tsrm_virtual_cwd.c file?

Re: [AOLSERVER] Again, Segfault with Aolserver, PHP, SquirrelMail
My next suggestion will require learning a bit of gdb, but
I'd try setting a breakpoint on line 298, and when it stops
I'd inspect what's actually contained in *tmp.
Why they built *ptr (and thus, *tmp) the way they did
baffles me, too.
One suggestion, delete line 287 (I think) which I'm marking
with *** :
} else { /* Concat current directory with relative path and then run
realpath() on it */
char *tmp;
char *ptr; *** THIS LINE ***
The locally scoped *ptr masks the *ptr defined at the
function scope (char *ptr, *path_copy;) ... I don't
think this is the culprit, but who knows. Removing line
287's definition shouldn't cause any additional problems
after reading the code.
Try making this small change, and recompiling the PHP
module, and see what happens.
