Improvment
Description:
H5config.h and H5pubconf.h are generated by configure. It does
not have the #ifndef _H5config_H ... #endif guard to prevent
duplicated definitions if it is included more than once.
It is messy to try make configure to put in those guards.
Solution:
HDF5 has set an internal rule that H5public.h includes H5pubconf.h
and H5private.h includes H5config.h. Source files should NOT include
H5config.h or H5pubconf.h directly but include it via H5public.h or
H5private.h respectively. The #ifndef ... #endif in the H5public.h
and H5private.h would prevent repeated definitions from repeated
include.
Adjusted H5FDstream.c and H5FDstream.h to follow this rule.
Platforms tested:
modi4, eirene.

Code cleanup.
Description:
Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the
extra warnings. Including a few show-stoppers for compression on IRIX
machines.
Solution:
Changed lots of variables' types to more sensible and consistent types,
more range-checking, more variable typecasts, etc.
Platforms tested:
FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)

Purpose:
Port to Windows platform
Bug fix
Description:
The Stream VFD is ported to Windows now.
Also fixed a bug where an application terminated when it got a SIGPIPE
due to sending/receiving on a closed socket.
Solution:
The socket stuff is treated different under Windows when using
the MS compilers to build HDF5. They define their own socket datatype
and have closesocket() instead of close(2) to close sockets.
Also there are different header files for all the socket stuff.
So I introduced my own socket decriptor datatype in H5FDstream.h
which should be used to pass in external sockets. This datatype
is mapped to either 'int' (UNIX-type sockets) or 'SOCKET' (Windows).
In the code the error code checking was adapted according to the
socket datatype used. Also, for Windows you have to call a routine
to initialize the Socket layer before using it.
As a kind of bug fix, the process signal mask is now set to ignore
SIGPIPE signals which otherwise cause the application to terminate.
The driver read/write routines catch this and return an error code.
Platforms tested:
Windows NT, both with MS Visual C++ compiler and with GNU cc
It is interesting that when compiling with GNU cc under Windows
it is possible to use both Windows and UNIX-type sockets (either
one or the other). So I check for GNU cc and go for UNIX sockets
if possible.

Added source files for the Stream Virtual File Driver.
Description:
The Stream VFD allows users to stream complete HDF5 files
via socket connections between different applications.
Files which were created anew are flushed to any connected client
on each H5Fflush() or H5Fclose() operation.
Files which are opened as read-only will be read from a socket
on a H5Fopen() call.
The driver's H5FDset_fapl_stream() routine allows to pass in
several parameters such as an external socket descriptor,
some socket options, and flags for broadcasting a received file.
If an external socket is provided the Stream VFD would use that
for the socket calls. Otherwise it parses the filename argument
in H5Fcreate()/H5Fopen() for a 'hostname::port' parameter.
All files processed by the Stream VFD are kept in memory
(same way as the core VFD does).
Platforms:
Tested so far under Linux, Irix 32/64bit, OSF1, Solaris, Cray Unicos,
Hitachi SR8000, IBM AIX.
Not tested under Windows yet.
