Re: HTTPAPI/EXPAT update to Storrage model *INHERIT

I do not recall having any problems with storage model = *TERASPACE
Awhile back I was experimenting with having HTTPAPI using storage model *SNGLVL, but do all of it's memory allocations in teraspace. At that time, RPG did not support other storage models (only C did). My updates worked nicely, but caused compatibility problems with Expat which is written in C. At that time, C only supported teraspace when you used the storage model teraspace... so it was a compatibility issue.
If you are on a current release, you should be able to change the INSTALL and MKEXPAT code to add the teraspace storage model, and I suspect that all will work properly, since RPG now supports the teraspace storage model.
If you want to experiment with my support for using teraspace allocations, you can enable it by editing CONFIG_H and defining USE_TS_MALLOC64 and TERASPACE. This should also work, allowing for >16MB allocations if you are on a current release, since ILE C has been updated to allow teraspace allocations with 128bit pointers without changing it's storage model.
I have not experimented with these recently as I have not had a need for allocations that large.

I do not know what problems Scott had with Expat. But I as far as I can
say, I do not have any problems after having changed the storage model

asked me for the list of service programs, he had to change for
WSDL2RPG. I do not run programs with storage model *TERASPACE but I
assume that this guy does. At least that is what he wanted to do.

Below are the commands I sent to him:

CHGSRVPGM SRVPGM(WSDL2RPGRT) TERASPACE(*YES) STGMDL(*INHERIT)
CHGSRVPGM SRVPGM(RADDATZ/MIME) TERASPACE(*YES) STGMDL(*INHERIT)

The default compile options used create the modules as *snglvl. You can modify MKEXPATCL in QCLSRC to include the teraspace options and try it out.

If I recall correctly, there is something in the archives about some strangeness with Teraspace enabled HTTPAPI and Scott disabled the options for future use. The changelog carries this message:
    - Added teraspace feature to HTTPUTILR4 to allow very large
         spaces in xlatedyn(). Disabled for now due to compatibility
         problems in Expat.

This was "way back" in 2007 and version 1.17. I am pretty sure no one has looked at it since. Maybe you can figure it out!

As far as updating Expat, Scott said this recently:
I see they now have 2.1.0.  I have not looked into that one.  I have not run into any need for an update, so haven't updated it.

Subject: HTTPAPI/EXPAT update to Storrage model *INHERIT

Hi.
I am currently looking into updating all my RPG programs/service programs to run with Storrage model *TERASPACE.
But I’m using HTTPAPIR4 and EXPAT and for some reason I’m unable to change the EXPAT service program to Storrage model *INHERIT/*TERASPACE Is there plans to update these service programs to support this option?
Has anyone tried this?
Also the EXPAT that is included with HTTPAPI is version 2.0.0 but there seems to be a version 2.1.0 on http://www.libexpat.org is there any plans to update to this version?



Cheers
