OpenVMS VAXDEBU04_071 VAX V7.1 DEBUG ECO Summary
TITLE: OpenVMS VAXDEBU04_071 VAX V7.1 DEBUG ECO Summary
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for DEBUG on OpenVMS V7.1. This kit addresses
the following problems:
Problems addressed in VAXDEBU04_071 kit
o The debugger's source view oscillates horizontally (steady
state) after an upgrade to Motif V1.2-5.
Images(s) Affected:
- [SYSLIB]DEBUGSHR.EXE
- [SYSLIB]DEBUGUISHR.EXE
- [SYSLIB]VMSDEBUGUIL.UID
Problems addressed in VAXDEBU03_071 kit
o Examines (checks) of global/shared data often show stale values.
o Monitor view performance suffers severe degradation when the
number of monitored items increases. For example, expanding a
900-element aggregate takes more than 20 minutes! The
performance loss continues even when monitored items are
collapsed or removed (even across runs/reruns). The
performance degradation first started in OpenVMS V7.0.
Problems addressed in VAXDEBU02_071 kit
o The debugger sometimes displays the wrong source and symbolic
information. That is, sometimes it reads the DSTs from the
wrong image or DSF file.
o Some commands, with several different languages, yield messages
similar to:
%DEBUG-E-OPNOTALLOW, operator 'AND' not allowed on given data
types
Problems addressed in VAXDEBU01_071 Kit
o Some VAX steps in PASCAL programs fail and cause severe errors,
for example, %SYSTEM-F-RADRMOD.
If there is a step range that includes a HALT instruction, then
the TBIT trap gets raised. That is, do not optimize stepping
performance for such ranges. Unfortunately, there are other
problems with this optimize algorithm that were fixed in later
releases. So to properly fix the essence of the problem, this
new optimization, for this stream, it must also be able to
recognize entry masks, and to adjust the low end, as well as
the high end, of the stepping range.
INSTALLATION NOTES:
The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VMScluster, they should
be rebooted or you should install this kit on each system in order to
make use of the new image(s).
