6.7.0 (was 6.7.0.7) 2008-10-09
Installation:
Added rpcgen(1) output to distribution (e.g., ldm6_clnt.c,
ldm_xdr.c) and removed unconditional use of rpcgen(1) from
makefiles. This was done because rpcgen(1) on a Mac OS/X
10.5.1 (Darwin 9.1.1) system generates output that's
incompatible with the "rpc" subpackage.
Slightly modified the configure(1) script to work around
non-standard tr(1) utilities.
Added the typedef "prod_class_t" to the header-file "ldm.h"
and changed all code and documentation to use it instead of
the typedef "prod_class". This was done to allow "ldm.h" to
be processed by a C++ compiler. The typedef "prod_class"
still exists for backward compatibility -- though it is no
longer used in the code. Both C and C++ programmers should
now use "prod_class_t" instead of "prod_class".
Added "typedef" for "rpc_inline_t" to "rpc/types.h" to
support output of rpcgen(1) on SunOS 5.11 systems.
Ported to Fedora 8. The log file of the system log daemon
is "/var/run/rsyslogd.pid".
Ported to Darwin 9: corrected misdefinition of OPEN_MAX as
10240 by ensuring that the XOPEN_SOURCE and
XOPEN_SOURCE_EXTENDED macros are defined on that platform.
Feedtypes:
Changed the primary name of the FT27 feedtype from "NNEXRAD"
to "NEXRAD3" to accomodate such data regardless of source.
"NNEXRAD" is an understood alias for that feedtype.
ldmadmin(1):
Added checking of LDM configuration-file syntax to "start"
command.
Modified the "pqactcheck" command. By default, it now
checks the syntax of every pqact(1) configuration-file that
is associated with an EXEC entry for pqact(1) in the LDM
configuration-file. LDM configuration-file entries like
"EXEC pqact -f CONDUIT" (i.e., with options but with no
explicit configuration-file) are correctly handled.
Changed the default size of the product-queue from 400
megabytes to 500 megabytes.
Changed setting of PATH environment variable in ldmadmin(1)
script to use $bin_path and $PATH only.
Added initialization of local variables to functions in the
ldmadmin(1) script to accomodate Perl interpreters that no
longer perform default initialization.
rpc.ldmd(1) (LDM server):
Adapted parsing of timestamps in .*.info files to Darwin 9.1.1:
replaced use of strptime() with sscanf() (strptime() conversion
specification must be separated by non-alphanumeric characters).
pqact(1):
Made each decoder its own process-group leader. This should
improve the performance of decoders like GEMPAK's
dcgrib2(1).
Added "-metadata" and "-nodata" options to the PIPE action
of pqact(1).
Changed behavior if a corrupt state-file is read. Before,
the process would exit. Now, it continues with the most
recent data-product (same as if the state-file didn't
exist).
Adapted pqsurf(1) to handle multiple BOYC reports in
composite SHIP bulletins.
Added code to the parser of feedtype expressions to prevent
an infinite loop upon encountering two consecutive UNION (|)
operators.
pq(3):
Removed retry attempt from write-locking fcntl() call in
file "pq/pq.c" because only fatal signals could occur.
Misc:
Improved some log messages.
Slightly improved rtstats(1) man-page.
