File: /outgoing/iris_patches/8.00/README800

This is a summary of the IRIS 8.00 patches available on the SIGMET
ftp site.  File last updated 6 Feb 2004.  The general proceedure
for installing patches is:
 1) Move the file platform/foo.gz.v# to your IRIS_BIN directory and
    remove the ".v#"
 2) Rename the file it will replace (e.g. "mv foo foo.old" )
 3) Uncompress the new file (e.g "gunzip foo.gz")
 4) Set ownership and mode to exactly match the old file
    (e.g. "chown operator foo", "chgrp users foo", "chmod 775 foo")

============================= 8.00.0 ===============================

show_machine_code.gz.v0
SGI platforms only: The version of show_machine_code on the 8.00
cdrom incorrectly showed the version as 7.32.9.  This interferes
with the correct operation of irisnet, since irisnet uses this
to detect the version of remote systems.

============================= 8.00.3 ===============================

RainbowToIris.gz.v3
This version of the Rainbow scan data format converter adds
the current time to all log messages.

sigbru.gz.v3
This version of sigbru allows users who are not root to make
backups.

============================= 8.00.4 ===============================

product.v4.gz
This version of the product generator fixes a bug in the NDOP 
product.  The NDOP product was showing degrading quality and 
missing rows and columns if the NDOP resolution was finer than 
3 times the resolution of the ingest input data.  This bug
is fixed in the IRIS release 8.05.  Be aware that even with the 
change, there is diminishing new information available as you 
zoom in to resolutions finer than the input data.

============================= 8.00.5 ===============================

product.v5.gz
Includes 2 changes to the COMP product:
1) Now fills in correctly the product generation time in the header.
   It was copying the generation time of the first input.
2) Modified rule 4 of the scheduling algorithm.  It now will only
   trigger making the product if data outside the time window arrives
   for a site not already found in the composite.  This means that we
   are still assuming that each site sends data in time order, but
   one site can be a lot slower than the others.  This is essential
   to correctly composite radar with different scan periods.

============================= 8.00.6 ===============================

product.v6.gz
In addition to the changes above, also includes repairs to the 
RAIN1 and RAINN product scheduling algorithm.  Case 2 of the 
scheduling algorthm was not working correctly on systems configured
to make products based on local time.  It was running to early 
in the Eastern hemisphere, and waiting to long in the Western 
hemisphere.  This bug was introduced in release 7.31, and is
fixed in release 8.06.

Case 1 was working correctly, so you can set your time backwards
and remake all the products correctly.
