Changes
Introduction
This is a summary of the changes to Monsanto NQS as released by the
Univesity of Sheffield.
We are most grateful for the contributions made by other
individuals and/or organisations.
Version 3.37
This is the last release of the product under the name
`Monsanto-NQS'. The next release will be the first beta release of
a POSIX.1-compliant source tree, and will be numbered v3.50. The
new name of this product has not yet been decided. The v3.50 beta
release will be announced on the `NQS-Developers' mailing list, as
normal.
Native 64-bit IRIX Support
The makefile ./proto/Makefile.sgi6.64 can be used to compile a
native 64-bit version of Monsanto-NQS.
The makefile ./proto/Makefile.sgi6 still produces 32-bit binaries
for IRIX 6. It is likely that this option will be removed at some
point in the future. At the minute, I don't know what the issues
are, and so it stays.

Modified Makefiles
For the first time, the file ./proto/Makefile is now supplied. Edit
this file to specify the NQS directories to install into, and then
uncomment the correct line at the end of ./proto/Makefile to include
the correct Makefile for your platform.
The INSTALL file has been updated accordingly.
All platforms are affected.
Thomas Eifert & Stu
Version 3.36.7
NOTE: This version was only released for testing purposes.
HPUX 8 Support Improved
You can now use the makefile ./proto/Makefile.hpux8 to ensure
successful compilation on HPUX-8.
To help distinguish between the two, the HPUX-9 specific makefile has
been moved to ./proto/Makefile.hpux9.
Stuart, with thanks to Brian M Bullen (b.m.bullen@stir.ac.uk) and
Michael Shepard (michaels@jake.cem.unsw.edu.au)
IRIX 5 Support Improved
IRIX 5 and IRIX 6 now share the same code for using /proc -
previously IRIX 5 used /dev/kmem where IRIX 6 used /proc. This
code hasn't been tested on IRIX 6 yet, but appears to work fine
on IRIX 5.

AIX Compiler Drivers
The compiler for IBM RS/6000 based systems by default allocates very
large amounts of data segment space, whether it is required or not.
This interferes with ongoing work to provide a proper scheduler for
NQS.
Inside the directory ./rzxl, you will find new drivers, plus a
comprehensive README and full installation instructions.

Thomas Eifert (Eifert@reze-1.rz.rwth-aachen.de)
Non-ANSI Compilers Detected
I've added a couple of lines of code which will ensure that using
a non-ANSI C compiler to compile Monsanto-NQS will result in an
error in ./h/hqs.h. This makes it easier for me to determine when
to advise a site to upgrade their compiler (perhaps to GNU C).

OSF/1 SIGSEGV Fixes
OSF/1 would segmentation fault when attempting to print out a
machine ID (as assigned by nmapmgr) during boot up (when generating
error messages about being unable to determine the local mid).
Fixed.
NOTE: There may be more of these which I've not found yet, at other
stages of NQS.

AIX Nice Values
AIX now correctly uses the BSD interface to setting nice values for
jobs.

Stu
Environment Variable Fixes
When constructing environments for child processes, NQS was failing
to correctly count the length of some of the strings in the
environment. Fixed.
NOTE: There may be more of these errors in NQS which I've not yet
uncovered.

Debugging Patches
Extra debugging information (available when the DEBUG level is set
to 5 or more using qmgr(1)) is now available, to assist in tracking
down initial problems.
In addition, the error reporting code in qsub was ambiguious - this
has been changed.
All platforms affected, but the code is aimed at tracking current
problems with OSF/1 3.2.
Stuart Herbert (S.Herbert@sheffield.ac.uk)
qstat Output Modified
Sequence number fields are now five characters long instead of the
original four.
All platforms affected.
Stu
Linux Support For FSSTND
I've modified Makefile.linux so that binaries should be installed
into directories under /usr/local. This should make installation
more compliant with the Linux FSSTND.

Stu
IRIX 6 Compilation Error Fixed
Makefile.sgi6 had a missing `-L.' on the LINKLIBS line, which meant
that the linker on IRIX 6 was unable to find the .a files in the
./proto directory. Fixed.

Stu
Version 3.36.6
Support For NCR UNIX (AT&T)
Monsanto-NQS now works on AT&T GIS (NCR) SVR4. Use the makefile
./proto/Makefile.ncr for compiling.
NOTE that the NCR C compiler fails to compile Monsanto-NQS - you
must use GCC instead (GCC 2.6.3 was used in this case).

Norm Rullo (normr@accelr8.com)
Support For OSF/1 v3.0
Monsanto-NQS now works on OSF/1 v3.0. Use the makefile
./proto/Makefile.decosf for compiling.

More HPUX Fixes
The HPUX fixes included in v3.36.5 were not complete, and have now
been fixed.

Solaris 2.1 Work-Around
On Solaris 2.1, getservbyname() doesn't accept NULL as the second
parameter - this has been changed.

CPU Limits Enforced On IRIX 5/6
IRIX 5 and IRIX 6 systems by default ignore the signals associated
with CPU time limits being exceeded - the signal handling has been
updated to ensure these signals are no longer ignored.

OSF/1 Compilation Failure Fixed
Compilation of Monsanto-NQS v3.36.5 was reported to fail on OSF/1
v2.0, partially because of an error in the HPUX code in v3.36.5,
partially because of the ANSI prototypes, and partly because of a
missing #include statement.
The OSF/1 Makefile has been changed to include the `-std1' switch,
which I understand will fix the problems with the ANSI prototypes.
The HPUX code (see above) has also been fixed.

Debugging Code Added
I am investigating a reported routing problem on SunOS 4. Code has
been added to the nmap database library to produce extra debugging
information in an attempt to discover more about this problem.

Version 3.36.5
Solaris 2 Cluster Fix
A bug in the Solaris 2-specific code in the libnmap was causing
requests between machines to fail. This bug has now been fixed.

HPUX Process Stats Fix
The call to pstat() in ./lib/shoqbydesc.c has (hopefully) been fixed.

SunOS & Solaris Process Stats
Code has been added for displaying extended information by using the
qstat(1) command.

Linux Makefile Added
Somehow, the source code at work (Solaris 2) didn't include a
makefile for Linux - I do all my Linux testing at home. The Linux
makefile has now been added to the distribution.

OSF/1 2.0 Support
Monsanto-NQS now compiles and runs on v2.0 of OSF/1.

Version 3.36.4
Please note that the new, IRIX 6.0 stuff, has not been tested by me,
simply because I don't have access to IRIX 6.
This release has successfully compiled and executed on Solaris 2.3
and Linux 1.1.53.
Stuart
IRIX 6.0 Support & ANSI Prototypes
Monsanto-NQS now compiles and runs on SGI's IRIX 6.0 release. As a
side effect of this, all code now has ANSI-style declarations.
Sites running SunOS 4 must either use `acc' or GNU's `gcc' compiler
to compile NQS from now on.

Dave Safford (d-safford@tamu.edu)
Processor Set Support
IRIX allows quite a variation in the configuration of its multiple
processor hosts using the `pset' command. Support for processor
sets is available for IRIX 6.0 right now, thanks to Dave - I'll make
it available to IRIX 5 users once I've had the opportunity to test
it.

Dave Safford (d-safford@tamu.edu)
qacct(1) Patched
The new `-m' switch of qacct can be used to show when a request was
submitted. Temporary files are now created in /usr/adm, rather than
/usr/tmp, before renaming.

The code which examined the file systems quota has been patched.

An internal copying error in qacct(1) has been rectified.

Version 3.36.2
New OS Supported : Linux
NQS now compiles and runs on Linux. Tested on Linux 1.1.54 with gcc
v2.2.58, although I can't see any reason why it should not work on
any standard Slackware distribution running a 1.0.x Linux kernel.
NOTE that because Linux lacks a plock() call, the NQS daemon cannot
be locked in memory from qmgr(1m). Otherwise, all the functionality
of NQS is available on Linux.

(karsten@kshome.ruhr.de)
Version 3.36.1
Compilation Problem
nqs_reqser.c has had two lines of code split into more lines to work
around an apparent compiler problem on Solaris 2.3.

Stuart
Compilation Problem
The makefile has been altered to link against libnqs.a and libnmap.a
using `-lnqs.a' and `-lnmap.a'.
