| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix/Code cleanup/New Feature Description: Correct problems with writing fill-values to external storage and allocate the data storage at the correct times. Also, mostly straighten out the strange code which allocates and fills raw data storage for datasets. Things are still a bit odd in that the fill-values for chunked datasets are written when the space is allocated, instead of in a separate routine, but there are two reasons for this: it's inefficient (especially in parallel) to iterate through all the chunks twice, and (more importantly) the space needed to store compressed chunks isn't known until we've got a buffer of compressed fill-values ready to write to the chunk. Additionally, add in the H5D_SPACE_ALLOC_INCR and H5D_SPACE_ALLOC_DEFAULT setting for the "space time", which incorporate the previous behavior of the space allocation for chunked datasets. The default settings for the different types of dataset storage are now as follows: Contiguous - Late Chunked - Incremental Compact - Early This checkin also incorporates a change to the behavior of external data storage in two ways - fill-values are _never_ written to external storage (under the assumption that writing fill-values is triggered by allocating space in an HDF5 file, and since space is not allocated in the file, the fill-values should not be written) and external data files are now created if they don't exist when data is written to them. The fill-value will probably need to be revisited at some time in the future, this just seemed like the safer course currently. I think I cleaned up some compiler errors also, before getting bogged down in the fixes for the space allocation and fill-values. Platforms tested: FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64 6.5 (modi4) in serial & parallel shortly.

| | | | | | | | | | | | | | Additional regression tests & bug fixes Description: There was no testing for the H5Dget_storage_size function and it seemed to be having problems with compressed, chunked datasets, so write some tests to verify that its working correctly. Also, fix case for allocating storage early for chunked datasets Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel

* [svn-r5662] Purpose:Quincey Koziol2002-06-181-5/+0
| | | | | | | | | | | | | | | | | Bug fix. Description: The chunking code was using internal allocation routines to put blocks on a free list for reuse, instead of using the system allocation routines (ie. malloc, free, etc.). This causes problems when user filters attempt to allocate/free chunks for their algorithm's use. Solution: Switched the chunking code back to using the system allocation routines, we can address performance issues with them if it becomes a real problem. Platforms tested: Linux 2.2.x (eirene) && IRIX64 6.5 (modi4)
* [svn-r5536] Purpose:Quincey Koziol2002-06-051-37/+43
| | | | | | | | | | | | | | | | | New feature. Description: Added a "small data" block allocation mechanism to the library, similar to the mechanism used for allocating metadata currently. See the RFC for more details: http://hdf.ncsa.uiuc.edu/RFC/SmallData/SmallData.html This reduces the number of I/O operations which hit the disk for my test program from 19 to 15 (i.e. from 393 to 15, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5259] Purpose:Quincey Koziol2002-04-251-34/+27
| | | | | | | | | | | | | | | | Code cleanup Description: Previously, the I/O pipeline (pline), external file list (efl) and fill- value (fill) structs were passed down the raw data function call chain, even into and/or through functions which didn't use them. Since all three of these pieces of information are available from the dataset creation property list, just pass the dataset creation property list down the function call chain and query for the information needed in a particular function. Platforms tested: FreeBSD 4.5 (sleipnir)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: The H5Gget_objinfo() function was not setting the 'fileno' field in the H5G_stat_t struct passed in. Solution: Added a "file serial number" to each file currently open in the library and put that in the 'fileno' field. If a file is opened twice (with H5Fopen) and the VFL driver detects that it is the same file (i.e. the two file structures have the same "shared file info" in the library's memory structures), they will have the same serial number. This serial number has two drawbacks: - If a VFL driver doesn't/can't detect that two calls to H5Fopen with the same file actually _are_ the same file, each will get a different serial number - If the same file is closed and re-opened, the serial number will be different. It is be possible to fix the second drawback for many VFL drivers, but it would be a lot of effort and probably isn't worth it until we've got a good reason to do it. Dunno if we'll ever be able to fix the first drawback... Platforms tested: FreeBSD 4.5 (sleipnir) VS: ----------------------------------------------------------------------

| | | | | | | | | | | | | | | | | | Bug Fix Description: When file space was returned to the file space free-list for reuse, occasionally raw data allocations which used space from the free-list would overlap with the metadata accumulator and get over-written with the cached information in the accumulator, corrupting the data. Solution: Check if the space about to be recycled on the free-list is going to be used for raw data and also overlaps with the metadata accumulator cache, avoiding using space that fits those criteria. This fixes bug #701 Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4696] Raymond Lu2001-12-111-0/+5
| | | | | | | | | | | | | | | | | Purpose: Modify H5Fclose behavior Description: The HDF5 actual file close behaves in several ways in terms of if there are still objects(dataset, group, datatype) opened in file. Solution: Added a new file access property, file close degree. It has four values, H5F_CLOSE_DEFAULT H5F_CLOSE_WEAK H5F_CLOSE_SEMI H5F_CLOSE_STRONG The way a file is closed is decided by these values. Platforms tested: IRIX64 6.5, SunOS 5.6, FreeBSD 4.4

| | | | | | | | | | | | | | | | | | Bug Fix Description: The file metadata macros generate unaligned access warnings on the IA64 architecture. Solution: Got rid of bogus big-endian vs. little-endian differentiation when encoding and decoding file metadata and use proper set of macros to prevent unaligned access problems. This fixes bug #672. Platforms tested: FreeBSD 4.4 (sleipnir)

* [svn-r4355] Purpose:Quincey Koziol2001-08-141-14/+14
| | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | Code optimization Description: Minor tweaks throughout the optimized regular hyperslab code to increase speed.

| | | | | | | | | | 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.

| | | | | | | | | | | | | | Bug Fix Description: When parallel I/O is turned on, there were some macros used in the H5D routines which poked around in the H5F_t structure. This breaks the privacy of that structure and ties the H5D code too tightly to the H5F_t struct. Solution: Added a small function to retrieve the the value (driver_id) needed from the H5F_t function. Platforms tested: Eyeballed only, Albert needs this right away...
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-284/+97
| | | | | | | | | | | | | | | 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.

* [svn-r2611] Purpose:Quincey Koziol2000-09-281-0/+6
| | | | | | | | | | | | | Rearrange code Description: The data sieve buffering code for contiguously stored datasets was wedged in the H5F_arr_read/H5F_arr_write routines. Solution: Created a new H5Fcontig.c to hold I/O routines for contiguously stored datasets (like H5Fistore.c for chunked dataset I/O routines) and moved data sieving code into those routines. Platforms tested: Solaris 2.6 (i.e. baldric)

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.

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).

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.

* [svn-r1418] Modified H5Tconvert to require a dataset transfer property ↵Quincey Koziol1999-07-031-0/+5
| | | | | | | | | | | | | list ID as the final parameter (so that VL datatypes have a way to pass in the custom memory allocation routines). Fixed a conversion bug when VL fields were part of a compound datatype that was causing the no-op conversion routine to be used instead of the vlen routine. Added the H5Pset_vlen_mem_manager and H5Pget_vlen_mem_manager routines to allow users to provide their own custom memory allocation routines for VL data read in from the file and reclaimed with H5Dvlen_reclaim. Finished coding on H5Dvlen_reclaim so it works now.
* [svn-r1292] Changes since 19990430Robb Matzke1999-06-021-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- 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.

* [svn-r1276] H5D.c:Albert Cheng1999-05-251-0/+1
| | | | | | | | | | | | | | | | H5F.c: H5Flow.c: H5Fprivate.h: Joined work by Quincey, Robb and me to eliminate the initial writes of BOOTBLOCK when the file is first created. Also, eliminate the repeatedly encoding of BOOTBLOCK in the flushing code. Introduced the eof_written flag to indicate when it is not necessary to go do a dumb write at eof. (But something is not right if the userblock is not zero.) H5Fmpio.c: Added code to allow setting the MPIO debug output mask via the environment variable H5F_mpio_Debug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./tools/h5ls.c Added a `--address' (`-a') switch which causes h5ls to display file addresses for raw data. For contiguous datasets it's just a nice simple number, but for chunked datasets it's a list of logical dataset coordinates, file addresses, filter masks, and storage sizes. Changed `--dump' switch to `--data'. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h Enhanced the indexed-storage B-tree iterator so it can dump raw data addresses (and other info) to the standard error stream. Added H5Ddebug() so h5ls has a way to dump addresses for datasets. I'm not sure what else this API function should do, so I think we should discuss it before we document it. So far, h5ls is the only thing that uses it, and we can easily change that. ./src/H5Tconv.c ./test/dtypes.c Finally had a chance to verify Paul's H5T_conv_s_s (general string to string conversions) bug fixes and incorporate them into H5T_conv_f_f (general floating-point to floating-point conversions) and H5T_conv_i_i (general integer to integer conversons). Thanks Paul. ./src/H5D.c ./src/H5S.c ./src/H5Sprivate.h Added performance timers around data space read and write callbacks. They were already there for the gather/scatter callbacks. The timings for read/write callbacks are displayed along with gather/scatter when data space debugging is turned on. ./bin/iostats Updated to print totals. Added a `--fast' option that doesn't do any output except the totals and is much faster. ./bin/trace Changed __unused__ to UNUSED to match source code. ./config/gnu-flags Updated error message for pgcc. I've sent bug reports to the pgcc people but the new version still has the same bug. ./configure.in ./config/conclude.in ./config/depend.in Fixed dependencies for non-GNU makes when run in a directory other than the hdf5 source tree. Updated GNU `make dep' rules to copy the distributed dependencies for non-GNU makes into the source tree when run in some other directory.

This will allow us to pass additional parameters to the I/O functions without having so many arguments to worry about. This fixes a bug I introduced last Friday for parallel HDF5 ./src/H5B.c Fixed decoding of B-tree keys when iterating through the leaves of the B-tree. This fixes a bug for applications that are adding new entries to groups and also listing the groups.
