Purpose:
Set compiler flag to force BSD compliance.
Description:
In order to set a socket descriptor into non-blocking mode
via ioctl(2) the Stream driver uses the FIONBIO constant.
Under Solaris this is defined only when compiled as BSD code.
I hope this doesn't break anything.
Platforms tested:
Solaris 5.7
Purpose:
Detect whether the system has the netinet/tcp.h header file.
Description:
The Stream VFD uses setsockopt(2) to set TCP_NODELAY on an opened
socket. This constant is defined normally in netinet/tcp.h
except for GNU cc under Windows where this header doesn't exist.
This template header file just contains the
#undef HAVE_NETINET_TCP_H
Platforms tested:
Windows NT, GNU cc
Purpose:
Detect whether the system has the netinet/tcp.h header file.
Description:
The Stream VFD uses setsockopt(2) to set TCP_NODELAY on an opened
socket. This constant is defined normally in netinet/tcp.h
except for GNU cc under Windows where this header doesn't exist.
Platforms tested:
Windows NT, GNU cc
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.
Bug fix...I hope
Description:
For some reason, libtool wasn't generating a .lai library file in
the .libs directory. It needs this to install things, apparently.
Solution:
Major hack! I force a ln to the "real" one libtools wants.

Bug fix
Description:
Forgot to decrement the number of objects in the group when removing
each one...
Solution:
Decrement the ID count when successfully removing each object from a
group.
Platforms tested:
None yet.
Bug fix
Description:
Fixed a very subtle bug that was corrupting the objects in a group when
H5I_clear_group was called and not all the objects in the group were able
to be cleared.
Solution:
Track whether an object as been deleted from each hash location's linked
list and only destroy the list when all the objects on the list are
actually removed.
Platforms tested:
None yet.

Bug Fix
Description:
People need to type in the full-path to the
attribute/dataset/etc. and weren't being told to do so by the
"usage" statement.
Solution:
Added an example and changed <names> to <path> to be more
explicit...
Feature
Description:
Allow dumping of variable length records. This is a first-time
stab at this. It doesn't break any tests on my Linux box and it
does output the variable length data, but it might look ugly (it
doesn't handle new-lines as of yet)...I'm open to suggestions on
what should be done next, what new features to add/remove...

Code optimization
Description:
Minor tweaks throughout the optimized regular hyperslab code to increase
speed. This set of improvements increase the benchmark time from taking
~5.46 seconds to ~4.50 seconds, or around a 20% further speedup.
Platforms tested:
Solaris 2.6 (baldric)
Bug fix
Description:
Recent changes to H5FD_read() added a new argument of type of
data to be written but the MPIO file driver call to H5FD_read()
was not updated. Also, the prototype of H5FD_read() in H5Fprivate.h
was "screened out", thus the compiler could not detect the inconsistency.
With the mismatched arguments, MPIO failed badly.
Solution:
Update the H5FD_read() call with the new parameter. Since the
call is used by H5Dread call so far, it is hardcoded to use
H5FD_MEM_DRAW as the value. If the call is used besides for
H5Dread, this parameter needs to be better defined.
(Still need to fix the prototype being blocked off.)
Platforms tested:

New tests
Description:
Added a new test file (tsaf.h5) for h5dump and h5ls. The test file was

tsaf.ddl is the expected output from h5dump.

Getting messages while compiling the || fortran stuff that it
didn't have a rule to make "H5Pf_parallel.c".

Bug fix.
Description:
Could not find the pre-created file for the H5S_MAX_RANK test
when --srcdir option is used. testhdf5 was looking for it
in the currect directory only.
Solution:
Make use of the value of the environment variable srcdir that
is passed to the tests. Compose the real location of the testfile
in order to open it even from a remote build directory.
Platforms tested:
Modi4, arabica, eirene
new feature
Description:
h5ls was not tested
Solution:
Added a test script, testh5ls.sh, to give h5ls some tests.
Since the output from h5ls is sometime machine dependent (e.g.,
Datatypes), can not compare them with expected output. For now,
run it against various hdf5 binary files. If it exits with 0,
consider it passes.

Features, kind of.
Description:
Separated the MPI features test into its own independent
program so that it can be tested on its own without too
much HDF5 stuff involved.
Added automatic removal of temporary test files after
the tests completed.

the SGI MPI problems of running out of internal mpi type entries.

Optimization for parallel I/O
Description:
When contiugous hyperslabs are defined (i.e. with the block=stride), the
library was only aggregating the hyperslabs together for the fastest
changing dimension.

row and output the entire contiguous section at once.

Bug Fix
Description:
Sed was complaining about "filename expected" when trying to
generate the .in files. The problem stemmed from the script sed
was generating in the conftest.s1 file. It needed the DEPEND
filename which wasn't being set.
Solution:
Fixed so that we check if DEPEND is zero before trying to set if
(if not using a GNU make program) instead of testing if DEPEND
has a value in it...I copied this incorrectly from the main
library's configure.in file...my bad.

Code cleanup
Description:
There's been a compiler warning about modifying a 'const' object in the
H5T_copy routine for several years now, which a few users have reported.
Solution:
Removed call to sort the old datatype (the const object) and changed the
code to work with unsorted datatypes.
Platforms tested:

Bug fix
Description:
"Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved in
the datatype object header message correctly.

Store endian-ness and precision in the datatype object header message and
added test to continue to track them working correctly.
This fixes bug #512.
