[Opengrads-devel] Merged and checked in GrADS 2.0.a2

[Arlindo da S. <da...@al...>]

All,
   I have just merged and checked in COLA's latest release. As before, none
of our patches have made to the COLA release, it is does not build
transparently with the supplibs-2.0.1. In addition to the merge, I have
implemented a couple of small enhancements to "fwrite" to allow me to better
interface GrADS v2 to python/perl, although the patch to enable fwrite to
work with named pipes (FIFOs) may be of general interest. I also added a set
of Grib-2 specific tests to pytests. See ChangeLog below for details.

To check out this version:

% gacvs co -P -r grads-2_0_a2-oga-1

 It builds out of the box with the supplibs-2.0.1.

 Jennifer, as always, you are more than welcome to incorporate these patches
to your codebase if you are interested.

  Cheers!

     Arlindo

>From the ChangeLog:

2008-05-10 <da...@op...>, Version GrADS 2.0.a2.oga.1
        * merged GRADS2_DEV_BRANCH with COLA's v2.0.a2.
        * From COLAS e-mail annoucing v2.0.a2:
            Features:
            * ready for use with GDS-2.0 to access 5-dimensional data
              sets via OPeNDAP
            * support for thinned grib2 grids
            * gribmap has -0 option for grib2
            * allows non-float data types for hdf coordinate axes
            Bug Fixes:
            * memory leak when replacing an existing defined variable
            * multiple fixes for netcdf/hdf handling (templating,
              zrev, %nodim%, et al.)
            * contour interval and label handling for double precision
numbers
            * changed 'query dims' output for ensembles
            * fixed gribmap's handling of data sets templated over T but not
E
            * fixed 'set annot' command and other minor bugs
        * Added Grib-2 specific tests to pytests/
        * src/gagx.c: Enhancements to fwrite in function gafwrt():
            * When fwrite output file name is "-" output is sent to STDOUT
            * Now uses stat() rather fopen(...,"r") to check is the file
already
                exists. This is important for using fwrite on FIFOs - a
deadlock
                occurs if a FIFO is opened for both read/write by a process.

Subject: NEW RELEASE of GrADS 2.0.a2
To: GRA...@li...


Dear All,I have posted a new version of GrADS:  2.0.a2. This version has
several new features and important bug fixes. The GrADS downloads web page (
http://iges.org/grads/downloads.html) has also been updated with links to
the source code and two binary releases (more binaries to follow as soon as
possible).

    Features:
    * ready for use with GDS-2.0 to access 5-dimensional data sets via
OPeNDAP
    * support for thinned grib2 grids
    * gribmap has -0 option for grib2
    * allows non-float data types for hdf coordinate axes


    Bug Fixes:
    * memory leak when replacing an existing defined variable
    * multiple fixes for netcdf/hdf handling (templating, zrev, %nodim%, et
al.)
    * contour interval and label handling for double precision numbers
    * changed 'query dims' output for ensembles
    * fixed gribmap's handling of data sets templated over T but not E
    * fixed 'set annot' command and other minor bugs

This release is a companion for GDS 2.0, which can now serve 5-D data sets.
COLA is running a 2nd GDS for testing on port 9191 that is serving
everything on the 9090 server plus GFS ensemble forecasts. Check 'em out at
     http://monsoondata.org:9191/dods/gfsens/
A public release of GDS 2.0 is forthcoming -- we are still testing. If you'd
like to help, please try using the 9191 server.

Please post comments and questions and bug reports here (low-tech bug
tracking is still in use at COLA). As always, I must be able to reproduce a
problem on my own systems in order to fix it, so keep that in mind when
reporting bugs.

Jennifer
