Robb,

Do you know anything about the problem described in this email with
the Perl netCDF interface not working with Perl 5.8?  Have you come up
with some sort of workaround for this problem to use with your perl
decoders?

Russ, et al.

Yes, there is a bug in perl 5.8.0 that doesn't have any work around. The
decoders appear to be working ok then usual behavior happens and no
recovery is possible. Currently, the decoders are being tested on perl
5.8.4 on a Linux box. The decoders have run w/o problems for a couple of
days but sometimes it takes as much as 4 days before the problems appear.
The solution is to upgrade to perl 5.8.4  More comments below.

Hi Jo,

Can you advise me on the right person at Unidata to contact about the
problem my guys are having with a NetCDF interface, please?  They seem not
to be getting adequate response through the mail lists.

Thanks,

Philip

Here's a quick summary of the NetCDF problems with the Perl interface:

1) The current version has a bug that we really need fixed: for NetCDF
variables which are arrays of bytes, it only gets the first element of the
array. Our doppler quality fields are stored this way. I can verify this
problem.

There is either a bug in netcdf-perl or in the your routine calling
netcdf-perl. It would help if I could look at your code  with some
sample data to test.

2) The updated NetCDF perl does NOT compile on our system. Or many others.

What systems: boxes/os's

3) The guy who would fix this says he's overcommitted and that this is a

low

priority (as in "this is not going to be fixed anytime soon"):

http://my.unidata.ucar.edu/content/support/help/MailArchives/netcdf-perl/msg
00120.html

4) The PDL (Perl Data Language) NetCDF interface does correctly handle

byte

variables. I've tested all of this on a couple test NetCDFs Linda made for
me.

Are you saying, byte vars are handled correctly but array of bytes are
not?


Robb...

The maintainer, Steve Emmerson, has basically said "If you want to fix it,
you
volunteer to be the maintainer for this package".

I don't know what's the best way to approach this, but obviously there are
more options than I realized.... Let me know what you/I/we can/should do.
I'll
take any solution, as long as it's soon.

Jason
