* [svn-r8731] Purpose:Quincey Koziol2004-06-231-4/+0
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r7836] Purpose:Quincey Koziol2003-11-121-0/+1
| | | | | | | | | | Bug fix Description: Add H5MMprivate.h header, to fix builds. Platforms tested: Eyeballed it, too minor to require testing...
* [svn-r7829] Purpose:Quincey Koziol2003-11-081-1/+1
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Allowing the library to call malloc with a size of 0 bytes causes problems for some users, so we check for allocations of 0 bytes and disallow them now. Cleaned up some code which could call malloc with 0 size. Changed some code calling HDmalloc directly to call H5MM_malloc(), which allows us to check for 0 sized allocations. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7805] Purpose:Bill Wendling2003-10-311-11/+46
| | | | | | | | | | | | | | | | | | | | Bug Fix Description: The End of Address information needed to be kept by the SAP. Some processes were trying to get the EOA information in collective mode, but the action wasn't collective at the time. Solution: Keep the EOA information for the file on the SAP. Clients query the SAP to get/set it when needed. Platforms tested: Linux (w/ FPHDF5) Copper (w/o FPHDF5) (FPHDF5 specific, so no need for full testing) Misc. update:
* [svn-r7697] Purpose:Bill Wendling2003-10-221-7/+7
| | | | | | | | | | | | | | | Bug Fix Description: Was using HGOTO_ERROR within a "done:" block. Solution: Changed HGOTO_ERROR macro to HDONE_ERROR inside of a done: block. Platforms tested: Linux (Small change). Misc. update:
* [svn-r7494] Purpose:Quincey Koziol2003-09-191-2/+30
| | | | | | | | | | | | | | | | | | Bug fix Description: Buffer for decoding superblock's driver information was too small when using some VFDs (like the multi-file VFD). Also made FPH5 code more portable and obvious when it's broadcasting the superblock from the captain process to the other clients. Solution: Allocate the buffer for the driver information dynamicly Platforms tested: Copper No h5committest because it's already working on other platforms.
* [svn-r7367] Purpose:Bill Wendling2003-08-151-6/+5
| | | | | | | | | | | | | | | | | | | Update Description: Added an extra flag to the clear functions that triggers a "destroy" of the object being cleared if necessary. This is a fix for the FPHDF5 stuff which had an object sticking around after it was cleared. (In FPHDF5, some processes are in charge of destroying the object, but all processes might actually allocate the object.) Platforms tested: AIX (Copper: Fortran & C++) Linux (Verbena: Fortran & C++) IRIX (Modi4: Parallel & Fortran) (Sol is down) Misc. update:
* [svn-r6527] Purpose:Bill Wendling2003-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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-r6514] Purpose:Bill Wendling2003-03-201-49/+51
| | | | | | | | | | | | | | | | | | | | | | | | | 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:
* [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-r6427] Purpose:Bill Wendling2003-02-211-4/+8
| | | | | | | | | | | 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-r6423] Purpose:Bill Wendling2003-02-211-11/+45
| | | | | | | | | 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-r6390] Purpose:Bill Wendling2003-02-101-11/+20
| | | | | | | | | | | | | | | | Update Description: Removed some obsolete fields - such as the AC_subst_t object ID - which isn't needed. Fixed so that there are fewer global variables. There are still some left, however. Modified the client and server code so that it handles read requests better. There were some flaws in how this was done before (it was calling H5FD_read() instead of just returning the status that it couldn't find the metadata in the cache). Platforms tested: Linux
* [svn-r6379] Purpose:Bill Wendling2003-02-061-1/+1
| | | | | | | | | | | | | | Update Description: H5FP.c, H5FPclient.c, H5FPprivate.h, H5FPserver.c: Update. More progression towards the SAP as metadata cache. It only lacks the ability to take care of metadata allocations. H5FDfphdf5.[ch]: Start of a new driver for FPHDF5. Not fully implemented just yet... Platforms tested: Linux
* [svn-r6371] Purpose:Bill Wendling2003-02-031-14/+44
| | | | | | | | | | | | | | Update Description: Changes: - Added support for the server dumping metadata writes to a client. - Some of the code wasn't handling allocated buffers correctly (freeing twice). - Modified server so that it handles metadata only. Platforms tested: Linux
* [svn-r6336] Purpose:Bill Wendling2003-01-271-52/+79
| | | | | | | | | | | | | | | Update Description: This is the first conversion of the FPHDF5 code to be a metadata cache. There's an extra error message. I rewrote the sync/change code to be read metadata/write metadata instead. I still need to hook these changes into the HDF5 code so that it looks at the SAP first before checking the file for metadata. Platforms tested: Linux
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-5/+5
| | | | | | | | | | | | Code cleanup/new feature. Description: Split FUNC_LEAVE into API and non-API specific versions. This allows a solution to compiling this branch with C++, as well as reducing the size of the binaries produced. Platforms tested: FreeBSD 4.7 (sleipnir) w/serial, parallel (including MPE) & thread-safe
* [svn-r6220] Purpose:Bill Wendling2002-12-191-5/+42
| | | | | | | | | | Update Description: A few generic changes to the FPHDF5 code. Some error messages reworked a bit. Cleaning up in case of failure improved in some cases. Added another field to the synchronization messages... Platforms tested: Linux
* [svn-r6040] Purpose:Quincey Koziol2002-10-281-7/+19
| | | | | | | | | | Code cleanup Description: Add more comments and clean up small bits of the FPH5 code. Platforms tested: FreeBSD 4.7 (sleipnir), changes too minor to affect other platforms.
* [svn-r6029] Purpose:Bill Wendling2002-10-231-1/+2
| | | | | | | | | | | | Oops Description: The H5FPprivate.h file was being #included even if PARALLEL was turned off. Solution: put the #include of the H5FPprivate.h file within the #ifdef block so that it doesn't get included if H5_HAVE_FPHDF5 isn't defined. Platforms tested: Linux...
* [svn-r6025] Purpose:Bill Wendling2002-10-231-0/+284
Feature Add Description: New files for the Flexible Parallel HDF5 stuff. H5FP.c - Module housing the APIs to FPHDF5 H5FPclient.c - Module housing the internal client APIs H5FPserver.c - Module housing the internal server APIs H5FPpublic.h - Header for public APIs H5FPprivate.h - Header for private APIs H5Ofphdf5.c - Way of serializing FPHDF5 information to and from the SAP H5Oplist.c - Way of serializing a generic property list. Solution: [details about the changes, algorithm, etc...] [Please as detail as you can since your own explanation is better than others guessing it from the code.] Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? [If no, why not?] Other platforms/configurations tested? Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.
