#39 Cache compiled Tcl page bytecode

[Jamie Rasmussen]

AOLserver 3.3+AD13 would cache compiled Tcl page
bytecode instead of reloading the file every time the
page was hit.

Rob Mayoff implemented this in file.tcl and
tclcache.tcl (new). The feature relied on the ns_cache
command provided by the nscache module. (The code does
check for the availability of the command.)

The attached file includes file.tcl and tclcache.tcl.

Hi Jamie!

No files are attached. I'm in the process of cleaning up the
backlogs a little. Is this request still valid?

Odd, I don't know where the attachment went, I suppose I may
have completely forgotten to attach it way back when...

I originally submitted this while we were trying to bring
all of the AD13 bugfixes and features to 4.0 so that the AD
fork of AOLserver would no longer be necessary. I'm not
personally using this patch and can't say I've really tested
it or examined it in depth. These changes definitely aren't
in 4.0 though.

If someone else can make a case for why this patch is
useful, that would be great, otherwise I don't mind if it
this ticket is closed.

I believe the patch is very useful for performance reasons,
that's why Rob did it. Although I haven't tried it, I'm
pretty sure it DOES apply to the tcl/adp page pairs used by
the OpenACS templating system, so at least one large group
of AOLserver users should be interested in this for their
larger sites.

Please do not close the ticket until/unless someone actually
either implements this.

Could you post the patch you made against 4.0 again? If you
can, I'd be willing to try it out and test it a bit.
