Code checkpoint
Description:
The fractal heap code is reasonably stable and is passing all its
current tests, so checkpoint everything with CVS.
Also, add "statistics" module for v2 B-trees code, which is only a
stub right now.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
Linux 2.4 (chicago)
New features
Description:
Add "find node greater than or equal to key" and "remove first" operations
to skip lists.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Description: By default on VMS system file cannot be opened twice; also
VMS has file versioning. This brakes some of our tests.
Solution:
Tests are commented out with H5_CANNOT_OPEN_TWICE and H5_HAVE_FILE_VERSIONS
that are defined in the vms/h5pubconf.h file only. This change cannot affect
any other platform.
Platforms tested: heping, VMS server
Misc. update:
Bug fix/Feature
Description:
Modify the library to use rand_r, when available, instead of srand. If
rand_r is not available, it will try to use srandom/random, and then finally
fall back to srand/rand.
Solution:
A couple places in the library use the srand() function to seed the random
number generator. This can cause problems on certain platforms and could theoretically
cause problems for users who expect a certain sequence of random numbers following their
own call to srand().
Most platforms have an implementation of rand_r, which is identical to rand, except that
it allows for explicit storage of the seed value. The configure script will now check
for the existence of rand_r to facilitate its use in the library.
Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and
HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither
of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call
srandom if available, and fall back to srand otherwise.
Platforms tested:
heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine
is currently not available.
Misc. update:
Bug fix (sorta)
Description:
Disable the fractal heap tests until I can look into them more thoroughly.
(they are failing on 64-bit machines currently)
Platforms tested:
None - trivial change.
New feature & code cleanup
Description:
Update fractal heap to be able to insert objects into a direct block
hanging off the header.

Add files that I forgot in my last checkin.
Description:
cache_api.c cache_common.c cache_common.h are new files that result
from breaking the old cache test into two tests.
Solution:
See above.
Platforms tested:
h5committested before the last checkin. Will run another
h5committest shortly, but it shouldn't be necessary as there
are no new changes.
Misc. update:
Bug fix/additional tests
Description:
Add additional tests for holding open an object of a given type (dataset,
group, etc) while incorrectly trying to open that object with a different
type of API routine (i.e. using the group open call on a dataset, etc.)

Code cleanup
Description:
Check in some of the code cleanups from working on the external link
support. (This doesn't include any of the external link features)

Bug fix.
Description:
getenv_all, like some implementations of getenv, keeps an internal buffer
for the getenv values. Application must make a copy of the content of the
returned pointer before calling getenv_all again IF it wants to use the
first content later. The previous code violated this rule and caused
error.
Solution:
Did a small revamp of the h5_fixname to fix the above problem by moving
the getenv_all for HDF5_NOCLEANUP eariler to avoid it clashing the
call of getenv_all for HDF5_PARAPREFIX. No a good permenant fix. Need
to really recode this routine.
Platforms tested:
h5committested.
Bug fix.
Description:
getenv_all will be called even when it is NOT an MPI application.
Solution:
Moved the use of getenv_all("HDF5_NOCLEANUP") to fix_name so that it will
be invoked only if a parallel driver is used.
Platforms tested:
hand tested in copper.
bug fix 504
Description:
testpar/t_mpi would hang if $HDF5_NOCLEANUP is set. E.g.,
% env HDF5_NOCLEANUP=yes mpirun -np 3 ./t_mpi
This happened because the environment variables are not exported to all
mpi processes by the mpirun command. So, some attempted to do cleanup
while others don't and some hang waiting for others to act.
Solution:
Instead individual program checking getenv, they all just called h5_cleanup
no matter. h5_cleanup now uses getenv_all to check the $HDF5_NOCLEANUP if
it is in parallel mode.
Platforms tested:
h5committested, tested pp in heping too.
Feature
Description:
Added character encoding and attribute creation property lists.
Solution:
Attributes' character encoding is set via the ACPL.
The default is ASCII, with UTF-8 being the other option currently.
Platforms tested:
heping, mir, sleipnir, copper
Bug fix
Description:
Retrieving an object's name could fail (in various ways) under certain
circumstances (mostly having to do with mounted files).
Solution:
Re-write & simplify "get object name" code to fix error in a better way
than adding yet another hack to the previous pile of hacks... :-)

Bug fix
Description:
Fortran type generation was broken in two ways. Fixed both.
Solution:
Firstly, there were a couple of path problems. Fixed a typo and
specified the full path of a file.
Secondly, the dependencies weren't right when building with HDF5-specific
commands (make lib, make check-s, etc.). Tweaked dependencies
to fix the problem.
Platforms tested:
mir, modi4, sleipnir
Configure feature
Description:
Added 'make trace' target.
Solution:
Added tracing to 1.7. This was done automatically in 1.6, but left out
of 1.7 until now (oops!).
Tracing in 1.7 only happens manually, when the user types 'make trace.'
Tracing automatically requires more framework than it's worth.
I also fixed a couple of tracing bugs and ran trace.
Platforms tested:
mir, sleipnir, modi4
Misc. update:
Bug fix
Description:
Before this checkin, 'gmake check-s' would fail if there was a file in
the current directory named 'check-s'.
This is fixed under gmake (not sure how to fix for other makes).
Solution:
check, progs, install, etc. are what gmake calls "phony" targets,
which means that no file should be created. These targets can be
specified by a line of the form
.PHONY: check progs install ...
Automake adds this line for targets it knows about, but HDF5 has a
lot of custom rules. This checkin adds a .PHONY line for those rules.
I believe that only gmake recognizes the .PHONY line (at least, pmake
doesn't seem to), but a partial solution is better than none.
This error should occur very rarely anyway (the user has to manually
create files with names like 'build-check-s' or '_test').
Platforms tested:
mir, sleipnir, modi4
More tests
Description:
Add more tests for proper behavior of groups with different group
creation property settings.

Bug fix
Description:
Fixed bug in hl/src Makefile that was deleting y.tab.c.
Running bin/reconfigure changed a few other files as well (somebody
probably updated Makefiles.am but forgot to bin/reconfigure).
Solution:
Automake in its wisdom adds the line "rm *.tab.c" to every distclean
in every directory. I assume that it assumes that such files are
generated during the build. Supplied an empty distclean-compile
target to remove this line from the Makefiles.in.
Platforms tested:
mir, sleipnir, shanti
New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
with it - the format will change again before the release and you will not
be able to read your old files!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
New feature
Description:
Add in baseline "object copy" code from Peter [in the form of a new API
routine: H5Gcopy()]. There's still some work to do (like handling variable-
length datatypes and possibly support for references) and it hasn't been tested
on mounted files yet, but the core functionality is there and working
correctly.
I've also got a set of patches to update the 1.6 branch with tweaks to
keep the branches mostly in sync, but Elena will kill me if I import them
before the 1.6.5 release is out... :-)

Bug fix/feature
Description:
Added support for -shlib in h5fc and h5c++.
Made check-install use -shlib when only shared libraries have been installed.
Solution:
h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against
shared libraries.
When static libraries are disabled, the examples Makefiles will automatically
use the -shlib option to link against shared libraries. Thus,
--disable-static and make check-install should work together.
Platforms tested:
heping(disable-static, enable-static, fortran, c++), modi4 (disable-static, fortran, c++, parallel, enable-static)
Bug fix
Description:
Failed parallel tests now cause make to exit with an error.
Solution:
Edited config/conclude.am to throw an error if parallel test programs fail.
Platforms tested:
heping, modi4
Added additional targets to build-all
Description:
Surveyed files to find out which ones are not built.
Added test/space_overflow and perform/benchpar to programs built with
--enable-build-all.
Discovered that tools/misc/pdb2hdf5 and tools/misc/h5import were
obsolete and deleted them.
Platforms tested:
mir, modi4, sol
Misc. update:
Update of release file and removal of --enable-pdb2hdf5 to follow.
Bug fix
Description:
test/gen_new_fill.c used some old APIs that didn't compile with the current
library. Brought it up-to-date.
Some other files (test/gen_old_*) are designed to be compiled only
with older versions of the library. Removed rules to try to build
them in the current Makefiles.
Platforms tested:
mir
Bug fix
Description:
Changed configure.in to use an environment variable TR to set the path
to the tr utility.
Solution:
There are two kind of tr on Solaris with slightly different syntax.
HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers
have needed to make sure that the "right" tr was found before the
wrong one in their path; now they can use an environment variable.
Platforms tested:
mir, shanti, sol
Misc. update:
Forgot to update release notes. Off to do that now.
Bug fix
Description:
Changed the name of a file from the last fix.
createnoenc.c is not gen_noencoder.c
Solution:
This is just a more standard name for the file.
Platforms tested:
tested in previous check-in; forgot to commit to cvs.
Makefile bug fix
Description:
Previously, automake didn't output rules to build perform/mpi-perf or
the test/gen_* programs.
Now these can be built by typing 'make mpi-perf' (or 'make foo') or by
configuring with --enable-build-all.
Solution:
Automake doesn't like having rules for programs it doesn't build. Tricked
it by having these programs built "sometimes"--whenever the user enables
--build-all. This should be used mostly for testing and to ensure that
these helper programs compile.
***IMPORTANT***
These programs do *not* currently compile. When --enable-build-all is used
(not the default), gen_new_fill fails because it uses an old API. This is
an existing "bug" that has simply been exposed by this checkin.
Platforms tested:
sleipnir, modi4, sol
Misc. update:
Avoid bug for family file driver backward compatibility with 1.6.
Description:
Because there is no srcdir on windows, string pathname should be
initialized as NULL before using strcat.
Solution:
Changed the code as above.
Platforms tested:
too minor to test.
Misc. update:
Bug fix
Description:
Check in Kent's fixes to hyperslab rebuilding code that should correctly
detect situation when different sub-hyperslabs exist in a higher dimension.

Too minor to require h5committest
Bug fix
Description:
Fix "double root open" bug and apply same fix to datasets & named datatypes.
Also fix bug in symbol table entry lookup code that would "transfer" an
object from one file handle to another file handle when the two file handles
were opened on the same actual file.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
bug fix.
Description:
When a parallel test script test fails, make would continue because the
way it was setup inside a for loop. Fixed it by issuing an exit 1 inside
the loop.
There was also a typo error in the newer command comparision that it
must be $${chkname} in order to be valid. Also, the test script itself
was not checked in the newer lists. All fixed.
Platforms tested:
h5committested and also hand tested in heping pp mode.
Repair synchronization bug in the metadata cache in PHDF5
Also repair numerous other bugs that surfaced in testing the
bug fix.
Description:
While operations modifying metadata must be collective, we allow
independant reads. This allows metadata caches on different processes
to adjust to different sizes, and to place the entries on their dirty
lists in different orders. Since only process 0 actually writes
metadata to disk (all other processes thought they did, but the writes
were discarded on the theory that they had to be collective), this made
it possible for another process to modify metadata, flush it, and then
read it back in in its original form (pre-modification) form. The
possibilities for file corruption should be obvious.
Solution:
Make the policy that only process 0 can write to file explicit, and
visible to the metadata caches. Thus only process 0 may flush dirty
entries -- all other caches must retain dirty entries until they are
informed by process 0 that the entries are clean.
Synchronization is handled by counting the bytes of dirty cache entries
created, and then synching up between the caches whenever the sum
exceeds an (eventually user specified) limit. Dirty metadata creation
is consistent across all processes because all operations modifying
metadata must be collective.
This change uncovered may bugs which are repaired in this checkin.
It also required modification of H5HL and H5O to allocate file space
on insertion rather than on flush from cache.
