Bug fix
Problem:
On Solaris2.5, once the library has been compilied with any type of
optimization, a bus error comes up in the "dtypes" test.
Solution:
The problem appears to be in the compilers' version of memcpy() that
is used when optimized. Apparently, the same optimization problem
is not associated with the similar function memmove(). So, as a
solution to this problem, memmove() is substituted in for memcpy().
Platform tested:
Solaris2.5
----------------------
./INSTALL
Reorganized and added some additional examples.
./MANIFEST
./aclocal.m4 [NEW]
./configure.in
./configure [REGENERATED]
./src/H5config.h.in [REGENERATED]
./bin/ltconfig [NEW]
./bin/ltmain.sh [NEW]
Added tests to determine how to compile shared libraries and
how to link programs with them before the libraries are
installed. Also how to install and uninstall shared
libraries. The configure step also prints the names of the
config files it's trying to load for easier debugging.
./bin/config.guess
./bin/config.sub
Replaced with a newer version from GNU. The changes we made
to that file to report `irix6.x' and `FreeBSD' without version
numbers have been incorporated into configure.in instead. In
the future, do not change these two files (see the top of
configure.in instead). By the way, this update was required to
get shared libraries working.
./config/linux [REMOVED]
./config/linux-gnulibc1 [NEW]
./config/linux-gnu [NEW]
./config/alpha-dec [REMOVED]
./config/alpha-dec-osf4.0 [REMOVED]
./config/dec-osf4.x [NEW]
./config/irix5.3 [REMOVED]
./config/irix5.x [NEW]
./config/irix64 [REMOVED]
./config/freebsd
Moved config files around to agree with output from the new
config.guess. The linux file was split into gnu (RedHat),
gnulibc1, and gnulibc2 versions. The alpha-dec file was
removed (I think it was unused) and the alpha-dec-osf4.0 was
changed to dec-osf4.x. The irix5.3 file renamed to irix5.x and
the irix64 file was renamed to irix6.x. The freebsd file was
changed to point to linux-gnulibc1. These changes were tested
on:
Linux 2.0
Linux 2.1
FreeBSD 3.2
Irix 5.3
Irix64 6.2
Irix64 6.4
HP/UX 10.20
OSF1 4.0
./config/alphaev56-dec-osf4.x
./config/irix64
Added warnings similar to linux/freebsd about using compilers
with known bugs.
./config/commence.in
./config/conclude.in
./src/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
Added definitions for shared libraries. This has been tested
on the following systems:
Linux 2.0
Linux 2.1
FreeBSD 3.2
Irix 5.3
Irix64 6.2
Irix64 6.4
HP/UX 10.20 static only
OSF1 4.0
If you want to disable use of shared libraries (you probably
do for development purposes since it takes a lot longer to
compile and because you have to run dynamically linked
programs in a special way if the library hasn't been
installed) then add `--disable-shared' to the configure
command line. This is all documented in the INSTALL file.
./bin/release
Temprarily commented out the MANIFEST checking when running
under svf since svf is about to be replaced by a newer
version. This change only affects error checking during the
release process.
./Makefile.dist
./Makefile.in
Added `make check' which does the same thing as `make _test'
since the former is endorsed by the GNU coding style and
people are used to it. The old `make _test' still works too
(and so does `make test' if you use GNU make).
----------------------
./INSTALL
Added instructions for using other compilers on Irix platforms.
./configure.in
./configure [REGENERATED]
./src/H5config.h.in [REGENERATED]
./src/H5private.h
The presence of <sys/sysinfo.h> and <sys/proc.h> is only
checked on DEC/Alpha because there are too many problems
including these headers on other systems.
./config/irix6.x
./config/irix64
Removed `-ansi' and added a comment. Converting an ASCII UTC date
and time to a time_t value is not defined by ANSI or Posix but
is available if we don't use `-ansi'. This allows the dataset
modification time messages to be read properly by
H5Gget_objinfo().
./src/H5Tconv.c
Fixed a compiler warning.
./test/dtypes.c
./test/hyperslab.c
./test/istore.c
Fixed compiler warnings in printf() statements.
----------------------
./INSTALL
Added warnings and a disclaimer about GNU, DEC, Irix64, and NT
compilers that generate incorrect machine code.
./configure.in
./src/H5private.h
Detects and includes <sys/param.h> which is needed on FreeBSD
before <sys/proc.h> even though we only really using anything
from <sys/proc.h> on the DEC Alpha.
./config/irix64
Turned off warnings for duplicate definitions from the linker
because -lnsl on irix has the same stuff in it as -lc.
./config/irix6.x
Split up the CC and CFLAGS settings like with irix64 so that
compilers besides `-n32' can be used.
./bin/snapshot
The snapshots are tagged with names like hdf5-1_1_52 which is
similar to the way the releases are tagged (cvs doesn't allow
dots in tags).
./test/dtypes.c
./src/H5private.h
./src/H5Tconv.c
Fixed some alignment violations on the DEC when using high
optimization levels. The DEC incorrectly optimizes certain
memcpy() and memmove() calls when the source argument is not
word aligned if the call looks like it's copying an atomic
data type.
./test/hyperslab
Worked around code generation bugs in the Irix64 Mongoose 7.00
compiler by casting some `unsigned long' values to `unsigned'
in an expression.
./src/H5Ocomp.c
Fixed a place where %d was used to print a size_t.
Bug fix
Problem:
This bug is coming up as a bus error on some machines
(fuga, spank) in the "fillval" test. At higher levels of
optimizations, H5detect gets rid of a statement which is to
be used in alignment tests. Because of this, SIGBUS is never
delivered, and the alignment constraints of the machine are
not recorded correctly by H5detect in H5Tinit.c.
Solution:
By preventing the optimizer from getting rid of the statement
to be used in the alignment tests, SIGBUS is delivered as
expected, and the alignment constraints of the machine are
recorded correctly.
Platform tested:
Irix6.5(fuga), HPUX10.20(spank), Solaris2.5(Kryten)
----------------------
./config/irix64
The old (-32) compiler is now supported by setting envrionment
CC='cc -32'. The -64 compiler is the default or you can set
CC='cc -64'.

Fixed lots of warnings on Irix64. Mailed a few remaining
warnings in H5S to Quincey and a few in the dumper to
Ruey-Hsia.
fixed the H5Tinit.c so it had the correct endians. I must have been using
the wrong H5Tinit.c file for the past few weeks. Also added a few comments
to the h5config.h
----------------------
./src/H5F.c
./src/H5private.h
./src/H5Ipublic.h
./src/H5O.c
Fixed a rather nasty bug with file closing that caused the
file boot block to be updated incorrectly, effectively
truncating the file. The bug I fixed was triggered by:
1. Create a file, F
2. Open an object, X
3. Close file F
4. Reopen file F for read/write.
5. Create and close some objects
6. Close file F
7. Close library (exit).
Step 3 pended the close because object X is still open, but
the file ID was removed from the H5I_FILE ID group. Step 4
created a new file because it didn't see any matching file on
the H5I_FILE ID group. Step 5 extends the file. Step 6 writes
the new file boot block to disk. Step 7 closes object X and
completes the close from step 3, writing the old boot block
information to disk.
The new behavior is that step 3 moves the file from the
H5I_FILE group to the H5I_FILE_CLOSING group. Step 4 searches
both groups and finds the file. Step 5 extends the file using
the same H5F_file_t struct as step 3. Step 6 closes the H5F_t
struct opened in step 3 but not the H5F_file_t struct shared
by steps 1 and 3. Step 7 closes object X which closes the
H5F_file_t from step 1, flushing the boot block which was
shared by all steps.
./src/H5F.c
Added some bulletproofing to file reference counting and
removed comments which no longer apply. Added H5F_flush_all()
and H5F_close_all() which apply to all files.
./src/H5A.c
./src/H5D.c
./src/H5F.c
./src/H5G.c
./src/H5I.c
./src/H5Iprivate.h
./src/H5R.c
./src/H5RA.c
./src/H5S.c
./src/H5T.c
Added the new H5I_free_t data type to describe the function
type to be passed as the `free_func' argument to
H5I_init_group().
./src/H5I.c
Bulletproofed the object removal functions. Removed comments
which no longer apply. Changed global variable names so they
don't violate the naming scheme. Added H5I_debug() that prints
the contents of an ID group. Removed H5I_inc_ref() because it
isn't used. Reindented a couple of functions.
./src/H5.c
./src/H5G.c
./src/H5Ipublic.h
Changed H5I_MAXID to H5I_NGROUPS to better relect the fact
that it's the total number of valid ID groups.
./src/H5Shyper.c
Changed hyperslab offset arrays to signed quantities to get
rid of warnings on DEC cluster.
./src/H5Flow.c
./src/H5Fprivate.h
Changed the objno argument of H5F_addr_pack() to be unsigned
to get rid of warnings on DEC cluster.
Bug fix
Problem:
Currently, when --enable_preduction --disable-debug modes are
selected during configure, the optimization level scheduled is
-O (-O2). Unfortunately, this level of optimization relaxes
too much the alignments necesary for the building, and testing
of the hdf5 library.
Solution:
Lower the level of optimiztion to -O1. This still maintains
required alignments.
Platform tested:
Irix6.5(fuga)
----------------------
./src/H5Shyper.c
Changed hyperslab offset arrays to signed quantities to get
rid of warnings on DEC cluster.
./src/H5Flow.c
./src/H5Fprivate.h
Changed the objno argument of H5F_addr_pack() to be unsigned
to get rid of warnings on DEC cluster.
----------------------
./src/H5.c
Fixed more dependency problems in H5_term_library(). There was
a bug in the previous version that could cause the wrong EOF
marker to be written to the boot block under certain
circumstances. Hopefully this fixes it although I don't ready
access to a test case (Mark Miller will test it).
./src/H5F.c
./src/H5Fprivate.h
Added an H5F_close_all() that is similar to
H5F_term_interface() but which doesn't close the
interface. Files that don't have open object headers are
closed, others are delayed until all object headers close. All
files are flushed.
