Forum OpenACS Development: Proposal to make slight adjustments to config.tcl

At the same time I also propose an increase of the default stacksize (without knowing exactly what would be a reasonable default) ...

If folks think this is reasonable, I'd like to commit it before the launch of 5.0.

Comments?

Don: I have no evidence that 500000 bytes are not enough. I just decided it was in accordance with Moore's law to increase it 😊

Joel: I dug up the AOLserver 4 installation instructions from here https://openacs.org/forums/message-view?message_id=135723 and what differs form 3.x - when it comes to tDom - is basically:

- a different tDom "configure" setting
- a symlink to the tdom.tcl "module"
- a couple of config.tcl file changes

It would be nice of course if the AOLserver 4 instructions (from the thread I mentioned) was merged with the documentation, but I'm not sure what your plan on this is for the upcoming (5.0) release, though.

Anyway, the changes I suggest to config.tcl and Jeff's check that the correct module is loaded (his check does not in itself load all the necessery tdom stuff) won't hurt folks who choose to employ AOLserver 3.x.

Russel: Sure, why not? Please let us know exactly what you think is a good expression (and a comment) to put in there. Thanks.

Here is what the README.AOL says in tdom 0.7.8:

For AOLserver 4.x:

      This version supports standard Tcl "pacakge require" mechanism
      so you can just:

        make install

      and it will install the library in the proper place. All you
      need to do then is to use "ns_eval package require tdom" to
      load the library and register it for every connection thread.
      You should add this command to some of the Tcl startup files
      in modules/tcl, so it loads the library on server startup.
