* [svn-r6578] Purpose:Quincey Koziol2003-04-035-68/+103
| | | | | | | | | | | | | | | | Code cleanup Description: Added lots of comments to existing filters, so they are easier to understand and use as examples for future filters. Cleaned up various bits of code, etc. Solution: Platforms tested: FreeBSD 4.8 (sleipnir) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6577] Purpose:Quincey Koziol2003-04-032-12/+18
| | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: The H5Pset_szip API call was forcing users to pass in their parameters in the same way as the internal representation of the filter parameters used by the library (as an array of unsigned values). Solution: Changed to pass in separate parameters in a more user-friendly format. Platforms tested: FreeBSD 4.8 (sleipnir) IRIX64 6.5 (modi4) w/parallel Misc. update:

* [svn-r6556] Purpose:Bill Wendling2003-04-015-72/+160
| | | | | | | | | | | | | | | | | | | Update & Bug Fix Description: The "free" protocol was missing. Added that to the server side. When doing a "create" of a file (with no other data structures created), the freespace in the file wasn't being reclaimed. Solution: After adding the free protocol, we put the burden of running through the FD_free function on the SAP instead of each client. Platforms tested: Linux Misc. update:
* [svn-r6552] Purpose:MuQun Yang2003-04-011-0/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support szip compression in HDF5 Description: This is where szip filter function is located. Solution: The filter function composes of "encode" and "decode" part, which is similar as deflate filter. One critical difference is: when szip decompresses the data, it needs to know the buffer size to hold the decompressed data in advance. Currently it's hard for HDF5 lib to give the buffer size easily. So to avoid this problem, in each chunk, we add a small header to hold the buffer size of each chunk. The code will use UINT32 ENCODE and UINT32 DECODE to finish this part of work. Platforms tested: Since there are changes of configure.in and configure,I didn't use h5committest. I tested with four platforms. 1) Linux 2.4 (eirene) 2) Solaris 2.7(arabica) 3) windows 2000(VS 6.0) 4) SGI IRIX6.5-64(modi4) For test 1)-3), only basic C tests were done For modi4 test, I tested 64-bit C,parallel and fortran. All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't e any real problems. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support szip compression in HDF5 Description: szip compression support is required by NASA ESDIS. The compression algorithm is good for scientific data. In HDF5, we add another filter function to make szip as a default compression package as we did for gzip(or zlib). In this check-in, a new function called H5Pset_szip was added into H5Pdcpl.c, this function is very similar to H5Pset_deflate. The only difference is SZIP needs four parameters from the user to get the compression done while gzip needs only one. So we pass a pointer to this function instead of an integer number. The description of the four parameters of szip should be in different documents. H5Z.c and other header files were simply modified to have HDF5 know szip. Solution: See the decription Platforms tested: Since there are changes of configure.in and configure,I didn't use h5committest. I tested with four platforms. 1) Linux 2.4 (eirene) 2) Solaris 2.7(arabica) 3) windows 2000(VS 6.0) 4) SGI IRIX6.5-64(modi4) For test 1)-3), only basic C tests were done For modi4 test, I tested 64-bit C,parallel and fortran.

| | | | | | | | | | | | | | | | | | | | | | | | | | To support szip compression in HDF5 Description: szip compression support is required by NASA ESDIS. The compression algorithm is a good compression algorithm for scientific data. In HDF5, we add another filter function to make szip as a default compression package as we did for gzip(or zlib). H5config.in needs to be regenerated by autoheader for SZIP flags. Solution: A new file called H5Zszip.c will be added in the Makefile.in Flags like: HAVE_FILTER_SZIP should be auto-generated by autoheader.

* [svn-r6527] Purpose:Bill Wendling2003-03-277-107/+58
| | | | | | | | | | | | | | | | | | | | | | | Bug Fix & Update Description: FPHDF5 was creating files which didn't have the EOA field in the superblock set correctly. It turns out that the SAP was keeping this information to itself instead of giving it to the client processes. Naughty SAP! Solution: Have the SAP send this information back to the clients so that they can update the superblock as necessary. This now creates a file (with just the root group) that looks correct! Only problem is that there's extra file space being allocated. Also, at program termination, there's an infinite loop... Platforms tested: H5committests (run by hand on burrwhite, arabica, and modi4) Misc. update:
* [svn-r6519] Purpose:Quincey Koziol2003-03-225-67/+85
| | | | | | | | | | | | | Bug fix/code cleanup/new feature Description: Fix h5debug to work correctly again, with all the changes over the past few months. Improved and cleaned up debugging output available in h5debug. Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6514] Purpose:Bill Wendling2003-03-207-147/+146
| | | | | | | | | | | | | | | | | | | | | | | | | Bug fix and Update Description: From Quincey's comments on the code I checked in last night: - In H5F_close call, the "private" processes should call the H5F_flush with the "CLEAR_ONLY" flag. - There's no need for a special case for FPHDF5 in the FD_real_alloc function since FPHDF5 doesn't define an alloc function. - The return type of H5Pset_fapl_fphdf5 should be herr_t instead of hid_t. I don't know how it got that way in the first place. - The variable names for MPI types and the structure typedefs should be switched: H5FP_request/H5FP_request_t to H5FP_request_t/H5FP_request and so on. - In the H5FP.c module, I was commiting the H5FP_request MPI datatype but using the wrong offset field... Platforms tested: Linux...will test on others, but these are mostly FPHDF5 changes. Misc. update:

| | | | | | | | | | | | | Update Description: When doing an allocation, check to see, if it's an FPHDF5 driver, if only the captain should be performing the allocation Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6505] Purpose:Bill Wendling2003-03-193-67/+179
| | | | | | | | | | | | | | | | | Update Description: Have the FPHDF5 module initialized on startup. Have only the captain process perform certain functions (like flushing during an F_close call or allocating the superblock). H5Fistore needed a few checks to see if it was working with an FPHDF5 driver. Done similarly to how MPI and MPIPOSIX drivers are checked.. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6504] Purpose:Bill Wendling2003-03-193-176/+201
| | | | | | | | | | | | | | | | | | | | | | | | | Why not? Description: Lots of changes. This is basically a "commit because there are a lot of changes" commit. The server now acts more like a metadata caching server. The dumping mechanism finally works (I think). At least in the test I did it seemed to write things back. There's a new MPI TAG to use (H5FP_TAG_DUMP) when dumping things. Changed a lot of the functions from passing a structure around to just passing a pointer to that structure. I have no clue why I did it the previous way... Um...And more synchronization stuff between the client and server. The protocol between the two was being broke in a couple of places. We're getting closer! Platforms tested: Linux (probably Modi4 too) Misc. update:
* [svn-r6503] Purpose:Bill Wendling2003-03-191-24/+41
| | | | | | | | | | | | | | | | | | | | | Bug Fix Description: The MPI datatypes we were committing weren't using the correct structure. Also, we needed to know the rank of the captain process inside of the BARRIER COMM. Solution: Changed to use the correct structure. Got the Captain process's rank and Bcast it to the "privates". Platforms tested: Linux Misc. update:
* [svn-r6502] Purpose:Bill Wendling2003-03-192-58/+154
| | | | | | | | | | | | | | | | | | | Update Description: More changes to the FPHDF5 file driver. Too many to mention here. Some highlights: - Addition of lock/unlock methods to the driver, though they aren't implemented fully just yet. - Extra query functions to determine various things about the file. (If this is the captain process, etc) - Fixes to make things work... Platforms tested: Linux Misc. update:
* [svn-r6501] Purpose:Bill Wendling2003-03-1911-63/+172
| | | | | | | | | | | | | | New Feature Description: Added support for the lock and unlock function calls for file drivers. Only FPHDF5 uses this feature. All of these drivers don't define lock or unlock methods. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6500] Purpose:Bill Wendling2003-03-191-57/+87
| | | | | | | | | | | | New Feature Description: Added function pointers for the lock and unlock functions. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6499] Purpose:Bill Wendling2003-03-191-17/+18
| | | | | | | | | | | | | Update Description: Added support for FPHDF5 wherever there was support for MPI/IO and/or MPIPOSIX. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6498] Purpose:Bill Wendling2003-03-191-8/+0
| | | | | | | | | | | | | | Cleanup Description: The H5O_FPHDF5 object was left in this header file by mistake when the H5Ofphdf5 module was removed Solution: Removed it. Platforms tested: Linux
* [svn-r6497] Purpose:Quincey Koziol2003-03-1912-56/+73
| | | | | | | | | | | | | | | | | | | Finish code cleanup Description: Wrap up the conversion of H5F_flush's multiple boolean flags into a single bitfield of flags by pushing the flags down into the H5AC_flush and H5F_istore_flush routines. Also, changed the flags from H5_FLUSH_<foo> to H5F_FLUSH_<foo> to be more consistent with rest of library. And reverted the changes to H5FDflush and H5FD_flush routines. Platforms tested: FreeBSD 4.7 (sleipnir) Solaris 5.8 (sol) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6496] Purpose:Bill Wendling2003-03-194-85/+159
| | | | | | | | | | | | | | | | | | | | | | Refactoring of Flush Logic Description: The Flushing logic passed in multiple flags to indicate what type of flush it was: closing, invalidate, alloc only. This made extending the function of the flush logic to handle other flags annoying. Solution: I changed it to be just one bitmasked flag to indicate what type of flushing to do. I also added the CLEAR_ONLY flag, which will be used in the FPHDF5 stuff. Platforms tested: h5committest doesn't work for me (my environment isn't setup on the other machines I guess). I tested it manually: Linux parallel & C++ Sol Fortran Modi4 parallel & Fortran.

* [svn-r6436] Purpose:Quincey Koziol2003-02-243-9/+1014
| | | | | | | | | | | | | New internal feature Description: Add internal API for building and working with heaps (H5HP). This will be used for the LRU algorithm in the new metadata cache code. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6433] Purpose:Quincey Koziol2003-02-245-63/+157
| | | | | | | | | | | | | | | Code/comment cleanup Description: Made more information about reference-counted strings private to the H5RS package by trimming the typedef used in H5RSprivate.h and switching from using macros for a couple of operations to using functions. Updated copyright information for a few of these files. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}
* [svn-r6431] Purpose:Quincey Koziol2003-02-242-12/+0

| | | | | | | Code cleanup (sorta) Description: Updated to new copyright information as I browsed these files.
* [svn-r6428] Purpose:Bill Wendling2003-02-222-1/+1
| | | | | | | | | | Bug Fix Description: Private header file was included in a public header file by mistake. Solution: Put the private header file into the .c module instead. Platforms tested: Linux 2.4 (see, I really did test it).
* [svn-r6427] Purpose:Bill Wendling2003-02-212-5/+10
| | | | | | | | | | | Update Description: Changed the H5FPinit() function to accept pointers to what the SAP Comm and SAP Barrier Comm should be assigned to. This is the first step in hopefully getting rid of the global versions of them altogether (but we'll see). Platforms tested: Linux
* [svn-r6426] Purpose:Bill Wendling2003-02-216-113/+209
| | | | | | | | | | | | Update Description: Final support addition for FPHDF5. Wherever there was an equivalent MPIO or MPIO/POSIX call/check, I placed an FPHDF5 call/check there as well, with the appropriate #ifdefs in place. The hdf5.h is updated with the H5FDfphdf5.h driver #include. Platforms tested: Linux & Modi4
* [svn-r6425] Purpose:Bill Wendling2003-02-213-390/+723
| | | | | | | | | | | | | | | | Update Description: Big change to the H5FD.c module: - Split apart H5FD_alloc and H5FD_free. H5FD_alloc was huge and H5FD_free had a freeing of the freelist part which I needed to call from the SAP. - Added support for FPHDF5. If it's a client, then it sends the allocation or free request to the SAP. The SAP will call the same code, but it'll actually do the allocation/freeing in that case. Platforms tested: Linux & Modi4
* [svn-r6424] Purpose:Bill Wendling2003-02-212-17/+127
| | | | | | | | Update Description: Added support for allocating and freeing space in the file. Platforms tested: Linux & Modi4
* [svn-r6423] Purpose:Bill Wendling2003-02-216-29/+293
| | | | | | | | | Update Description: Added support for the allocation and freeing of space in the file. This information is kept on the Server. Platforms tested: Linux & Modi4
* [svn-r6415] Purpose:Quincey Koziol2003-02-185-28/+58
| | | | | | | | | | | | | Code cleanup Description: Changed hard-coded magic number (32) for the maximum number of filters in a filter pipeline to use a symbolic constant (H5Z_MAX_NFILTERS) instead. This limit could (and probably should) be removed to allow an unlimited number of filters in a pipeline. Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6412] Purpose:Quincey Koziol2003-02-176-391/+1249
| | | | | | | | | | Code cleanup Description: Update dependencies and clean up a few warnings. Platforms tested: Linux 2.2 (eirene) w/parallel
* [svn-r6411] Purpose:Quincey Koziol2003-02-1740-1669/+1385
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.

* [svn-r6406] Purpose:Bill Wendling2003-02-142-115/+68
| | | | | | | | | | | | Update Description: Since metadata doesn't use a "set view" to do I/O, I moved the check for the use_set_view variable down into the "real" write routine. Also added a check for when the server is dumping metadata to the file. in that case, don't write this information to the SAP... Platforms tested: Linux
* [svn-r6402] Purpose:Bill Wendling2003-02-122-393/+236
| | | | | | | | | | | | | | | Update Description: Added the flush function. Modified so that it calls the FPHDF5 code for reading and writing. This involved splitting the write function up into three different parts to avoid lame goto's. There's some code which will copy a data xfer property list and add in there that we're "dumping" the data so that we can recall this layer when the SAP dumps metadata to a process... Platforms tested: Linux
* [svn-r6401] Purpose:Bill Wendling2003-02-123-68/+226
| | | | | | | | | | | | | | | | Update Description: Added a "metadata flush" function which allows the clients to force a dump of the metadata from the SAP. This should be done before closing the file. Modified the information stored on an "open" of the file. The filename is unnecessary, so I got rid of it. More integration with the File Driver code: Passing in a data xfer property list. Platforms tested: Linux
