[MacPerl-WebCGI] Updating a CGI

[David Steffen <steffen@biomedcomp.com>]

I'm working on a column for Perl Monthly on CGI programming with 
MacPerl and am particularly interested in flagging places where 
different installations (different Web servers, different versions of 
the MacOS, different networking setups) affect behavior. 
Unfortunately, I only have a few possibilities I can test myself, so 
I rely on what I have read in this group to help extend that list.

I recall a discussion in this group relating to the problems 
resulting from the 5 minute delay before a MacPerl CGI quits. 
Because the MacOS doesn't allow replacement of a running file, it was 
not possible to test a new version of the CGI until that 5 minutes 
ran out.  I have confirmed this behavior using Apple File Sharing.  I 
cannot confirm it using FTP transfer, but believe it would be the 
same.

However, I may have found a workaround.  If, using Apple File 
Sharing, you mount the remote Mac's volume on your Mac, and if you 
edit the CGI in place using MacPerl, you can save revisions to the 
CGI while it is still running, and on subsequent invocations, the new 
version is run.  The one cosmetic consequence is that you now see two 
copies of the CGI under the Apple menu; the old version and the new. 
(I suppose this wastes RAM as well.)

Comments?
