TITLE: OpenVMS ALPLIBR08_071 Alpha V7.1 - V7.1-1H2 LIBRTL ECO Summary
Modification Date: 04-DEC-98
Modification Type: Updated Kit: Supersedes ALPLIBR07_071
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 LIBRTL on OpenVMS Alpha V7.1 through V7.1-1H2.
This kit addresses the following problems:
Problems addressed in ALPLIBR08_071:
o For OpenVMS V7.0, the run-time library (LIBRTL) routine
OTS$CVT_TU_L (convert text unsigned to long) was made 64-bit
address aware and quadword conversions were added. This
resulted in a `signed' overflow check being performed in the
`unsigned' case. Consequently, some conversions were
reported as overflow errors when they were in fact good.
o For OpenVMS V7.0, the run-time library (LIBRTL) routine
STR$ADD (string add) was made 64-bit address aware to
support 64-bit string descriptors. This resulted in one
of the `input' parameters being overwritten with an
intermediate value. The documentation lists this
parameter as read-only.
o For the FORTRAN Run-time Library (RTL), ensure that a
large enough buffer is allocated, if the size the user
requested buffer is bigger than the current intermediate
buffer.
o The run-time library (RTL) routine LIB$GETDVI failed fo
CLASS_VS (varying string) descriptors. Varying strings
were most often found in PASCAL language programs.
Problems addressed in ALPLIBR07_071:
o The string copy routine STR$COPY_R_R8 accepts a source length
argument in a register. This should be interpreted as an
unsigned word, the upper portion of the register being masked
off.
o LIB$VM_MALLOC (used by C RTL routine "malloc") obtains memory
using $EXPREG. In the case where $EXPREG fails to return
enough memory to satisfy a given request, such "leftover"
memory is placed on a LIB$VM_MALLOC free list. This tends to
occur when a process has reached all its virtual address space
limit, or for some reason asks for an exceptionally large
memory allocation. The problem is that this "leftover" memory
is probably the last memory available to the process, and
interferes with any "last ditch" attempts to recover.
Another scenario is where a task can be performed in 2 ways,
one of which involves using a large amount of memory. This can
result in LIB$VM_MALLOC grabbing a large amount of virtual
memory and putting it on its free list.
Problems Addressed in ALPLIBR06_071:
o The wrong length was returned in the resultant-length field
from LIB$GET_FOREIGN in the case that the input string was
truncated. LIB$GET_FOREIGN was returning the original length
of the string instead of the truncated length.
o LIB$CONVERT_DATE_STRING handles 2-digit years from input by
selecting the current century as the default to use for the
century portion of the date. This behavior may not be
desirable for many customers since 00 would be interpreted as
1900 (and then as 2000 on 1/1/2000). Unfortunately, it has
been documented since V6.0 and therefore we could not see
changing the Y format without disrupting customers who expect
this behavior.
Problems Addressed in ALPLIBR05_071:
o Please see the problem description in the ALPLIBR03_071
documentation below. The problem described was not totally
resolved by the ALPLIBR03_071 remedial kit. This kit fixes
the problem.
Problems Addressed in ALPLIBR04_071:
o A "not valid type" error occurred as a result of a change in
LIBRTL.
Problems Addressed in ALPLIBR03_071:
o The LIB$CVT_DX_DX routine will return an access violation
status when called from BASIC with a zero length source
string. This may potentially happen with other languages as
well. This only occurs for NBDS to NBDS conversions. There
is an additional problem in NBDS to NBDS conversions, where
the length returned does not account for extra spaces on the
end of the string (excluding space padding).
Problems Addressed in ALPLIBR02_071:
o Memory leak in repeated calls to lib$init_date_time_context and
lib$free_date_time_context causes memory to be exhausted.
Problems Addressed in ALPLIBR01_071:
o When using the ACCOUNTING utility to format and display
accounting records, certain record types display erroneous
values for elapsed time and processor time.
o X-FLOAT numbers are not rounding correctly when doing
formatted I/O from Pascal.
o A hang will occur when LIB$FIND_IMAGE_SYMBOL is called
recursively. This manifested itself in a C++ program where
the recursive call to LIB$FIND_IMAGE_SYMBOL occurred because
of its use in a constructor.
INSTALLATION NOTES:
The images in this kit will not take effect until the system is
rebooted. If there are other nodes in the VMScluster, they must
also be rebooted in order to make use of the new image(s).
If it is not possible or convenient to reboot the entire cluster at
this time, a rolling re-boot may be performed.
During installation you may see the following message:
%INSTALL-E-NODELSHRADR, unable to delete image with shareable
address data -INSTALL-I-PLSREBOOT, please reboot to install a
new version of this image
This is not a cause for concern. It simply means that LIBRTL.EXE
was installed as a resident image, which is the standard configuration
for OpenVMS Alpha systems. The new image will not take effect until
the system is rebooted.
