Purpose:
Modify H5Fclose behavior
Description:
The HDF5 actual file close behaves in several ways in terms of if there
are still objects(dataset, group, datatype) opened in file.
Solution:
Added a new file access property, file close degree. It has four values,
H5F_CLOSE_DEFAULT
H5F_CLOSE_WEAK
H5F_CLOSE_SEMI
H5F_CLOSE_STRONG
The way a file is closed is decided by these values.
Platforms tested:
IRIX64 6.5, SunOS 5.6, FreeBSD 4.4

Code cleanup for better compatibility with C++ compilers
Description:
C++ compilers are choking on our C code, for various reasons:
we used our UNUSED macro incorrectly when referring to pointer types
we used various C++ keywords as variables, etc.
we incremented enum's with the ++ operator.
Solution:
Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
template)
Fixed usage of UNUSED macro from this:
char UNUSED *c
to this:
char * UNUSED c
Switched the enums from x++ to x=x+1

Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.

Purpose:
Implemented port hunting
Really catch SIGPIPE signals
Description:
Port hunting allows to try and bind to a successive port number
if the port number given in the filename is already used.
Because of a stupid typo in the code, SIGPIPE wasn't catched
which might have caused the sending side to hang.
Solution:
The Stream VFD's file access property list was extended by two
elements:
- maxhunt: how many successive ports to try if the one
given in the filename is already in use
Default is not to hunt for additional ports.
- port: port number which is finally used to bind a socket
This might be different to the port number
as given in the filename if port hunting is enabled.
The H5Pget_fapl_stream() can be used to obtain
this port number.

Description:
Changed

which it places in the .depend and Dependencies files. Also
regenerated the Dependencies to go along with this.

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.

more range-checking, more variable typecasts, etc.

* H5FD_stream_query: The `flags' argument is advertised to be output only. Therefore I
added code to zero its value before the feature bits
are assigned.

Under SunOS 5.5 the symbol FIONBIO wasn't known.

Also put the UNUSED qualifier in the right place in a function
argument list (gcc 2.7.2 didn't like it before the type name).

Bug fix
Description:
When the v1.2 compatibility code was turned on, internal functions in the
library were getting confused.
Solution:
Separated guts of H5Pget_driver call into an API function (the definition
of which depends on the compatibility switch) and an internal function
which always behaves like the v1.3/4 function. Replaced API function calls
in the library code with the internal function.

Bugfix
Description:
The socklen_t was hardcoded to be defined as int on architectures
other than Linux and SUN (Solaris).
Now it turned out that Solaris isn't consistent in this manner.
Versions earlier than 2.7 do not define this type.
Solution:
Check at configure time whether the socklen_t type is defined
by the system header includes. If not than this type is defined
to be 'int'.

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.

Feature symmetry
Description:
A while ago I needed to get the 'type' of data being accessed during writes
to the VFL driver, so I put in code to get the information down there.
Albert asked for the same information during reads, so I've added that in.

Purpose:
Just add a few lines so that it will not break windows platform.
Description:
netdb.h cannot be recognized by windows, use winsock.h in windows instead.
Solution:
adding the following lines at the beginning of H5FDstream.c.
If you don't like, you may do it in another way, just keep it work for windows.
#ifdef WIN32
> #include <winsock.h>
> #else
> #endif
Platforms tested:
I am only testing whether it will bother building objects on windows. I haven't tested whether it
will affect the testing results. Hopefully not.

Implemented new feature
Description:
Added data sieve buffering code to raw I/O data path. This is enabled for
all the VFL drivers except the mpio & core drivers. Also added two new
API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and
H5Pget_sieve_buf_size().
Platforms tested:
Solaris 2.6 (i.e. baldric)

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.
