The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver. Removed #warning about not having the stdio driver. Plans are to not implement it since the sec2 driver serves the same purpose and testing didn't show any difference in execution times between the two.

| | | | | | | | | | | | | | | | | | | | | H5.format.html Copy edits Beginning of revisions to bring the Specification up-to-date and move it to present tense Couple of new intro paragraphs, designed largely to offer the user a bit more context H5.user.html Datatypes.html Font correction and minor formatting changes. H5.user.PrintGen.html H5.user.PrintTpg.html New files to enable creating a searchable and printable version of the HDF5 User's Guide. These files enable the creation of a PDF file containing the entire document. H5.user.PrintGen.html controls the print job; H5.user.PrintTpg.html is the title page for the PDF volume.

Besides, the fact that something is a datatype is obvious because it starts with H5T_NATIVE_. ./tools/h5ls.c Added the new C9x data types. H5ls prints one of these types only if it doesn't match one of the builtin C types. Prints the OID for shared data types. Fixed a formatting bug with symbolic links which was introduced a few changes ago. The commandline has been changed so that objects from multiple files can be listed with a single command. Instead of specifying a file name and an optional list of objects, each thing to print is a file name and object concatenated. H5ls figures out how to devide the name into a file name and object name even when the file name part doesn't correspond to an actual Unix file. Old syntax: h5ls [OPTIONS] FILE [OBJECTS] New syntax: h5ls [OPTIONS] FILE[/OBJECT] [FILE[/OBJECT]]... Example ({X,Y} is expanded by the shell) Old command: h5ls -d ../test/x.data dir1 dir2 New command: h5ls -d ../test/x.data/{dir1,dir2} The filename is printed as part of the object name when full names are requested (--full or --recursive). If people really don't like this they can undefine a constant at the top of h5ls. Errors from the hdf5 library are turned off. Commandline switches of the form `--width 80' are accepted in addition to `--width=80'. This is more symmetric with single-letter switches that take two forms: `-w 80' and `-w80'. ./src/H5D.c Added tracing instrumentation for H5Dvlen_reclaim(). ./src/H5private.h Added casts to int for the isalpha() et al macros to shut up solaris warnings about char subscripts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- Remove changes from CVS ./bin/release Added a `--nocheck' switch which causes the script to not check the contents of the MANIFEST file against CVS. This is sometimes useful when you need to make a quick snapshot but the MANIFEST file is not quite up to date. ./src/H5D.c Removed warnings for unused variables ./src/H5Fprivate.h Removed the WIN32 definition for `uint' and changed the data type for `eof_written' from `uint' to `uintn'. Shouldn't this really be `hbool_t'? ./src/H5Odtype.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tpublic.h ./test/dtypes.c ./doc/html/H5.format.html Added support for bitfields and opaque data types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./doc/html/H5.format.html ./src/H5HG.c Fixed a bug in the global heap that caused H5HG_read() to write past the end of the buffer in certain cases. ./test/big.c The test is skipped if hdf5 was configured with `--disable-hsizet'. ./src/H5Ofill.c Data type conversions are implemented for the fill value. ./src/H5.c Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS, H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of the more cryptic H5I_TEMPLATE_* constants. ./src/H5D.c Removed prototype for H5D_find_name(). ./src/H5I.c The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS instead of being set by hand. We don't use the sign bit of hid_t; all valid hid_t values are positive so we can say things like `if ((file=H5Fopen(...))<0)'. Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry about rounding. Fixed H5I_get_type() so it doesn't always fail an assertion. ./src/H5E.c ./src/H5Epublic.h Added minor error H5E_MOUNT ./src/H5F.c ./src/H5Fprivate.h Added H5Fmount() and H5Funmount(). Mounting and unmounting works as documented but some of the other things aren't implemented yet, the biggest being current working groups always acting on the root of the mount tree, and H5Fclose() closing the entire tree. The rest of the stuff will be added shortly... ./src/H5P.c ./src/H5Ppublic.h Added the H5P_MOUNT property list but haven't implemented any particular properties for it yet. ./src/H5Gstab.c Hard links across files return an error instead of failing an assertion.

The string character set and padding method are saved to the hdf5 file instead of using defaults. Added conversion function from one fixed-length string type to another. ./test/chunk.c Fixed to work with new filter API

If an object header has this message then it's value is updated with the current time whenever anything changes in the object header. ./acconfig.h ./configure.in Alas, there seems to be no standard way to convert a string time like 19980727122800 in UTC to a time_t since mktime() only converts local times to time_t. So I've modified the configuration to check for various ways of getting the time zone information: * Added checks for the `tm_gmtoff' field of `struct tm'. * Added a check for the `timezone' global variable. * Added a check for `struct timezone'. * Added a check for BSDgettimeofday(). * Added a check for gettimeofday() although it doesn't actually set the timezone argument on some systems. * Added a check to see if `tm_zone' is a member of `struct tm'. * Added a check to see if `tzname' is a global variable. * Added a check to see if `struct tm' is defined in time.h or sys/time.h. It's not difficult to get the right UTC modification message into the object header, but some systems might have problems getting the right time back out (Irix64 is one) and those systems will report zero for the H5G_stat_t.mtime from an H5Gstat() call as if the mtime message isn't even present. It will, however, continue to be updated as normal. ./src/H5G.c ./src/H5Gpublic.h The H5G_stat_t struct now contains an `mtime' field which will hold the object modification time. If the object has no object modification time then the `mtime' will be initialized to zero. Fixed a bug in H5G_stat() that caused the `objno' field of the H5G_stat_t to be set incorrectly on some machines. ./src/H5D.c Writing to external datasets fail if the hdf5 file is not open for writing. A modification time message is added to the dataset object header when it's created and H5O_touch() is called from H5D_write() to update that message. ./src/H5T.c Fixed a bug in H5Tget_member_dims() that caused a segmentation fault if one of the output array arguments was the null pointer. Relaxed the member dimension checking in H5Tinsert_array() so it can also be used for scalar members. ./test/Makefile.in Added additional file names to the `mostlyclean' target. ./tools/h5dump.c ./tools/h5tools.h Increased the temporary buffer size to 1MB. Added support for printing compound data types with array members. When printing H5T_NATIVE_CHAR and H5T_NATIVE_UCHAR we escape double quote characters. ./tools/h5ls.c Changed the output format a little because we were starting to get too much info to fit on a line. Without `--verbose' each object occupies one line of output. Otherwise, additional information is printed below the object name: object file address, comment, and modification time. If `--dump' is given then the data is printed after the other information. ./test/cmpd_dset.c Changed the way the dataset is initialized to be more uniform.

The library currently just gives up if the version numbers don't match, but in the future the library could handle multiple versions of a message. ./test/testhdf5.c Removed an argument from the H5version() call that I missed last time.
* [svn-r516] Changes since 19980720Robb Matzke1998-07-201-9/+24
| | | | | | | | | | | | | | | ---------------------- ./doc/html/H5.format.html ./src/H5F.c ./src/H5Gprivate.h ./src/H5Oshared.c Added file alignment fields: the boot block has an extra reserved address field. The symbol table entry scratch pad space was reduced from 24 bytes to 16 bytes. The index permutation was moved earlier in the data type message for compound data types and extra padding was added. Four bytes of padding was added to the shared message format.

Otherwise some little endian machines complain (DEC Alpha) during encoding/decoding of file meta data. I chose to add alignment to the file rather than rewriting the ENCODE/DECODE macros for the little endian case. Completely rewrote the section on attribute messages. More alignment stuff will follow. ./src/H5detect.c Fixed a typo `nd'->`dn' ./test/dtypes.c Commented out conversion tests to/from `long double' on machines where it's the same size as `double' to get rid of compiler warnings. ./doc/html/Big.html Fixed a couple typos.
