V5.4-002 brings performance and scalability enhancements to GT.M:
- The previous implementation of local variables has been replaced by
one that scales well to large numbers of nodes at a given subscript
level. FIS has internally validated its scalability to over one
million nodes and also validated that it preserves or even slightly
improves upon GT.M's traditional fast performance for local
variables with smaller numbers of nodes.
- On 64-bit editions of GT.M, the previous per-region limits of
65,536 global buffers and 2GB shared segment size are no longer
limited by GT.M; of course, they remain limited by your actual
computing platform.
There are important enhancements to the trigger facility:
- Trigger -xecute commands can span multiple lines.
- The new ZTRIGGER command allows a trigger to be explicitly invoked
under program control.
- $ZTNAME replaces the deprecated $ZTCODE in the trigger signature.
- The now permitted use of $ZTRIGGER() within a TP transaction allows
trigger logic to be updated atomically within a transaction. Some
restrictions apply.
An "unlink all" capability for UNIX platforms allows a process to
disassociate itself from all routines that it has linked, release
memory, and continue execution with a new entryref at the top of the
stack; local variables and IO devices are preserved across the transition.
A new option generates code to evaluate elements of Boolean
expressions
in strict left-to-right order as an alternative to GT.M's default
behavior which stops the evaluation of Boolean expressions once the
final outcome is determined.
This release includes the field test release of a new gtminstall script
to simplify the downloading and installation of GT.M. [GT.M V5.4-002
itself is production grade software; the field test designation applies
only to the script.]
V5.4-002 contains numerous fixes, remedied mis-features, and smaller
enhancements. For details refer to the Release Notes
( http://tinco.pair.com/bhaskar/gtm/doc/articles/
GTM_V5.4-002_Release_Notes.html).
As the content management system for the FIS web site is undergoing
some major changes, the announcement may not appear on it till later in
the week. The software, however, is available in the usual locations,
including http://sourceforge.net/projects/fis-gtm
