iwgetmount() issue.

ksshah

Hello,

I am having problems with my Upload script -- edited version of (http://devnet.interwoven.com/site.fcgi/techlib/52656). I am using Teamsite::config::iwgetmount() to get the path to the current Teamsite mount i.e. replace server name in areaPath cgi variable with iwgetmount(). Now this works perfectly fine for clients which use Teamsite Content Center Interface on their networks. The client has a secure VPN portal application through which users can access Teamsite. For these users I am getting wrong values of iwgetmount(). I wanted to know if there is an alternative to this -- other than hardcoding the server mount. I am attaching the relevant portion of my upload script.

use CGI;
use TeamSite::Config;
my $cgi = new CGI; 

my $iwmount = TeamSite::Config::iwgetmount();

my $apath = $cgi->param("areaPath");

$apath =~ s|^//[^/]+|$iwmount|;

$apath =~ s|/|\\\\|g;

print $aptath;

This is the output apath for users on network.

apath: Y:\\default\\main\\limited\\ltd_portal\\WORKAREA\\folder

This is the output apath for users using teamsite through portal application.

apath: http:\\\\server-name\\default\\main\\limited\\ltd_portal\\WORKAREA\\folder.

I dont know why $iwmount dosent return the correct value -- Y: when over portal application.

this script is only run locally on the server? Or is it somehow run in different environments. Is it run the the iw_cgi_wrapper.cgi?

If this was a question. Then yes the script is locally on the teamsite server. And the script (performFileUpload.ipl) is called by promptFileUpload.ipl which is run via iw_cgi_wrapper.cgi...

my $iwmount = TeamSite::Config::iwgetmount();
my $apath = $cgi->param("areaPath");
$apath =~ s|^//[^/]+|$iwmount|; #(C2)
$apath =~ s|/|\\\\|g; # (B)
print $aptath; # (A)This is the output apath for users on network. apath: Y:\\default\\main\\limited\\ltd_portal\\WORKAREA\\folderThis is the output apath for users using teamsite through portal application. apath: http:\\\\server-name\\default\\main\\limited\\ltd_portal\\WORKAREA\\folder. # (C3)I dont know why $iwmount dosent return the correct value -- Y: when over portal application. #(C1)

(A) I assume this is a typo in your post and not your actual code - otherwise I'm surprised you see any output.

(B) There is absolutely no reason to change all forward-slashes to back-slashes - if anything you'd be better off doing the opposite ($apath =~ tr|\\|/|;)

(C1) What makes use think that $iwmount is any different when run over a portal application? It's not $iwmount that's different - it's $cgi->param("areaPath"); that's different - (what version of TS are you using? I don't believe that areaPath is an officially supported form element in 6.5 - unless you're running your script through wdpro_menu.ipl).

(C2) Your regex clearly says - Find two double slashes at the beginning of the string followed by any number of non-slash characters and replace it with the value of $iwmount

(C3) This output of $apath clearly shows that it begins with the string http: and not with the string // therefore your first regex doesn't change anything. So the question isn't:

" why $iwmount dosent return the correct value -- Y: when over portal application"it's

"why $cgi->param("areaPath") doesn't return a vpath when run over a portal application"Instead it returns a URL which your code isn't expecting.

Thanks for pointing out my error. I realized that after I posted last week. Our Teamsite environment : 6.1.0 Service Pack 2.
Testing it on Windows XP 2002 SP2.

I will try to debug the script -- look to replacing http:// with iwmount. Also one more question i had was i am passing variables (area_path) between CGI scripts (promptFileUpload.ipl -- the initial file input form for the user and performFileUpload.ipl -- the actual upload script) through hidden input variables within promptFileUpload.ipl. Is this a proper way to pass variables between cgi scripts. Also promptFileUpload.ipl uses CGI_lite and performFileUpload.ipl uses CGI. Could this be the reason my area_path is getting screwed up when it reaches the upload script. I checked with show_eng.cgi script and I see area_path as proper with //server-name//default...thanks again for the help.

Passing information from one CGI to another CGI (or even to the same CGI recursively) via hidden form variables is pretty standard and I believe the "accepted" way to do it.
