* [svn-r4620] Purpose:Quincey Koziol2001-11-201-28/+37
| | | | | | | | | Code cleanup Description: Get rid of IDs from internal function calls and some small cleanups from the old-stype => generic property list conversion. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4589] Purpose:Quincey Koziol2001-11-031-2/+3
| | | | | | | | Code cleanup Description: Clean up various compiler warnings from generic property updates. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4572] Raymond Lu2001-10-251-1/+1
| | | | | | | Purpose: Followup file access property list changes. Platforms tested: IRIX64, SunOS 5.7, FreeBSD.
* [svn-r4569] Raymond Lu2001-10-241-8/+23
| | | | | | | | | Purpose: Generic Property List Change Description: Changed file access list to the new generic list. Platforms tested: IRIX64, SunOS5.7, FreeBSD
* [svn-r4488] Purpose:Quincey Koziol2001-09-281-4/+4
| | | | | | | | | Fix on Kludge Description: Forgot another chunk of parallel I/O code that needed to change for the generic property list kludge... :-/ Platforms tested: Parallel Linux 2.2.18smp (eirene)
* [svn-r4396] Purpose:Albert Cheng2001-08-201-0/+3
| | | | | | | | | | | bug fix Description: H5FD_mpio_flush() would try to file seek negative if the file->eoa is 0 (e.g., doing mpio on the raw-file of the split file driver). Put in a code to catch this case by returning succeed immediately. Platforms tested: modi4(pp)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-1/+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. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4327] Purpose:Quincey Koziol2001-08-111-5/+13
| | | | | | | | | More code cleanups Description: Wrap up the code cleanups for changing the dataset transfer property lists over to using the generic property list code. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-4/+4
| | | | | | | | | Bug Fix, Code Cleanup, Code Optimization, etc. Description: Fold in the hyperslab speedups, clean up compile warnings and change a few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead. Platforms tested: FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
* [svn-r3914] Purpose:Bill Wendling2001-05-111-2/+12
| | | | | | | | | | | | | Replace Kludge with Another Kludge Description: The MPI_Get_count function isn't found on most systems. We need to replace this with a configure call which checks and defines the macro H5_HAVE_MPI_GET_COUNT or something. Solution: If-def'ed out the code for everyone (since H5_HAVE_MPI_GET_COUNT is never defined anywhere). Platforms tested: SDSC HP N9000
* [svn-r3781] Purpose:Bill Wendling2001-04-051-9/+9
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3256] Purpose:Albert Cheng2001-01-101-7/+6
| | | | | | | | | | Typo fix and comment Description: The FUNC_ENTER of H5FD_mpio_flush had a wrong function name. Corrected it. Also filled in the missing original author name. Added a 'this is collective.' to all collective functions. Platforms tested: It was just editing. Can't go wrong. :-)
* [svn-r3219] ./hdf5/src/H5FDmpio.cRobb Matzke2000-12-291-6/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2000-12-29 13:26:28 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_write: Avoid MPI_Get_count() when using the LAM implementation of MPI. This code must have other problems anyway because Kim Yates has a similar kludge in place to avoid negative return values from the same function. 2000-12-29 13:25:30 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_read: Avoid MPI_Get_count() when using the LAM implementation of MPI. This code must have other problems anyway because Kim Yates has a similar kludge in place to avoid negative return values from the same function. 2000-12-29 11:28:13 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_flush: Read and rewrite the last allocated byte of the file to insure that EOF>=EOA. 2000-12-29 09:32:49 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_write: Removed unused variable. 2000-12-29 09:32:15 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_write: Fixed a failure return value that should have been FAIL instead of NULL. 2000-12-29 09:31:47 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_read: Removed unused variable. 2000-12-28 16:09:31 Robb Matzke <matzke@llnl.gov> * H5FD_mpio_query: The `flags' argument is advertised to be output only. Therefore I added code to zero its value before the feature bits are assigned.
* [svn-r3120] Purpose:Albert Cheng2000-12-121-1/+0
| | | | | | | | | | | | | Bug fix Description: In H5FD_mpio_open, there was a mem-xfree of the file variable before it ever gets alloc'ed. This is inside a failure condition that rarely happened. But if it happens, it would be freeing a null pointer. Solution: Removed the error code. Platforms tested: Modi4 -64 parallel. (Everything still works. :-)
* [svn-r3010] Purpose:Quincey Koziol2000-11-281-5/+5
| | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3005] Purpose:Quincey Koziol2000-11-271-2/+2
| | | | | | | | Backward compatibility code Description: Add in code to allow the library to emulate the v1.2 API and behavior. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r2935] Purpose:Albert Cheng2000-11-151-2/+2
| | | | | | | | | | | | | | | | | Bug fix Description: The optimized MPIO code was not working with the TFLOPS machine. It kept reporting "can't convert from size to size_i" errors in H5FD_mpio_write() and H5FD_mpio_read(). Solution: The error was actually in H5S_mpio_spaces_xfer() in H5Smpio.c in which the variable mpi_count was declared as size_t (only 4 bytes big in TFLOPS) when it should be hsize_t (8 bytes big in TFLOPS). Corrected and also changed to use the (hsize_t) to case size_i in H5FD_mpio_write() and H5FD_mpio_read() since that is what it should be. Platforms tested: TFLOPS and modi4 (-64, parallel)
* [svn-r2811] Dan Wells2000-11-081-1/+1
| | | | | | | | | | | | Purpose: Bug fix. Description: The names of some entries did not correspond with the names in the FUNC_ENTER macro. This would cause inaccuracies during Pablo tracing. Solution: The names were changed in FUNC_ENTER to agree with the entry names. Platforms tested: Solaris, Irix, AIX, HP Vclass
* [svn-r2774] H5FD.c:Albert Cheng2000-10-311-4/+32
| | | | | | | | | | | | | | | | | | | | Purpose: Bug fix Description: H5FD_close() wiped clean the public information before closing the FD. This caused problem to the lower level close() which wants to verify it has indeed handed a valid file-driver to close because that information is wiped out prematurely. Solution: Moved the public information part cleaning after it is closed. H5FDmpio.c: Added in a bunch of assertion to make sure the file handle is indeed an MPIO file. Platforms tested: IRIX64 -64 parallel
* [svn-r2722] Purpose:Quincey Koziol2000-10-241-2/+2
| | | | | | | | | | 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. Tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2657] Quincey Koziol2000-10-101-1/+1
| | | | | | | | | | | | Purpose: Parallel Bug Fixes Description: Was out of sync with header file re-arrangements I checked in last night. Solution: Fixed to use new header files, etc. Platforms tested: O2K (modi4)
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-0/+1
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

This is absolute important. Test it out on at least two or three different platforms such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and 64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]

* [svn-r2057] Purpose:Albert Cheng2000-03-241-0/+1
| | | | | | | | | | | | | | Bug fix for parallel mode. Description: H5FD_mpio_tas_allsame was called for all cases, even when MPIO is not used for access. That corrupted the internal file handle structure. Solution: Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with MPIO access. Will call H5FD_mpio_tas_allsame only if this condition is true. Platform tested: O2K, both -64 and -n32 modes.

* [svn-r1915] Purpose:Albert Cheng1999-12-201-15/+21
| | | | | | | | | | | | | | | | | | | Bug fix. Description: When only p0 will write for allsame metadata, other processes returns with SUCCEED immediately. In some racing conditions, the other processes may start reading the metadata before p0 has finished writing them out. That results in errors. (I verified by putting an intentional delay in the p0 code. Other processes then got read errors always.) Solution: When only-p0-writes is the case, p0 will Bcast the result to other processes. This provides both a synchoronization and more valid logic since the other processes will return FAIL too IF p0 write fails. Also fixed a typo of the H5F_MPIO_DEBUG_KEY name. Also removed the incorrect #define's of FALSE and TRUE. They are already defined in H5private.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c Added additional elements to a variable initializer in H5Dvlen_get_buf_size() to shut up a warning message. Also added the API tracing call. ./src/H5F.c Added file opening optimizations. If the driver doesn't support the ability to determine when two file handles refer to the same file (like MPIO and GASS) then H5F_open() makes fewer calls to the driver's open callback. Also, if the tentative file access flags are the same as the original flags then H5F_open() makes fewer calls to the file device. ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h Added H5FD_get_class() so the library can get information about what file driver callbacks are defined. This will be useful when more optimization functions are added to the VFL, such as for MPIO derived datatype I/O. ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDmulti.c ./src/H5FDsec2.c The driver symbols (like H5FD_CORE, etc) are actually function calls. The functions were fixed to return correct values even after calling H5close(). ./src/H5FDmulti.c ./src/H5FDmulti.h Added support for opening a file when parts are missing (only if the caller explicitly allows that in the file access property list). Moved some common code sequences into macros or functions. Added better support for reopening files. All the application has to know is that the file is a multi file and the base name from which all the member names are created. More debugging output when the file is opened with the H5F_ACC_DEBUG flag. Fixed various bugs. ./src/H5Fistore.c Chunked raw data was accidently allocated as meta data instead of raw data. ./src/H5I.c The H5Iget_type() function fails when invoked with an old object ID (an ID which has been closed down). ./test/h5test.c Added an extra argument when setting the multi file access property lists so the test fails if it can't open one of the sub-files. ./tools/h5ls.c Improved the algorithm for deciding what file driver to use. It basically tries all of the predefined drivers and is now able to open family, split, and multi files without looking for special characters in the file name. Added `-e' and `--errors' switches which cause errors from libhdf5 to be reported on stderr in addition to the simple error message displayed by h5ls.

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.

---------------------- This extensive change is the virtual file layer implementation. I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes.

Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.
