If we enter a new web alias or change the web alias in the BlueOnyx Virtual
Site::Services::Web page, the vHost file (i.e site1) in /etc/httpd/conf/vhosts is written
correctly. However, if we clear the Web Server Aliases field, the vSite file does not
get re-writen to reflect the change. That is, a "null" entry in the field
should clear the aliases in the vHost file. It does not. The previous entries remain.
Deleting or renaming the vHost file causes it to be written correctly.
I replicated what you were doing. In the log file, 99% of the logs are
identical... There are some differences when you add an alias compared
to deleting an alias.
*Add an alias*
Jun 5 06:57:00 node2 cced(smd)[x]: client 6:[y]: SET 98 "webAliases"
"=" "&x.com&" "webAliasRedirects" "=" "1"
Jun 5 06:57:00 node2 cced(smd)[x]: client
6:handlers/base/vsite/change_net_info.pl: SET 104 fqdn =
"www2.compassnetworks.com.au" webAliases = "&x.com&" ipaddr =
"203.26.211.122"
Jun 5 06:57:00 node2 cced(smd)[x]: client
6:handlers/base/vsite/change_net_info.pl: SET succeeded
*Clear alias*
Jun 5 06:57:00 node2 cced(smd)[x]: client 6:[y]: SET 98 "webAliases"
"=" "" "webAliasRedirects" "=" "1"
change_net_info.pl is the trigger to update the alias file for a vsite.
The line below is from this file:
*_change_net_info.pl_: if ($vsite_new->{ipaddr} || $vsite_new->{fqdn} ||
$vsite_new->{webAliases})*
This IF statement appears to be our smoking smoking gun. What is this IF
statement actually doing? $vsite_new is an object that contains only
CHANGED fields. If we change an IP address, the new address will be in
$vsite_new->{ipaddr}. If this field is not changed, that will be empty.
Same goes for FQDN. Both of those fields are mandatory, so they will
never be empty. However, webAliases is optional. When we clear that
field, it will be an empty value. This if statement thinks nothing has
changed requiring an update to the alias file whenever we clear the alias.
*Solution:*
I had a look at the triggers for this handler. There are three variables
in the associated conf file.
/# handle configuration of various things
Vsite.fqdn perl:base/vsite/change_net_info.pl CONFIGURE
Vsite.ipaddr perl:base/vsite/change_net_info.pl CONFIGURE
Vsite.webAliases perl:base/vsite/change_net_info.pl
CONFIGURE
/
If the handler is only triggered whenever we update fqdn, ipaddr, or
webAliases .... we can just comment out that if statement totally...
because one of those things will change each and every time that handler
runs. I've tested this on my box and it looks good to me.
Michael... Are you happy with that fix? The only issue would be if we
add other triggers to that handler in future other than the three above.
Regards,
Greg.
