| | | | | | | | | | | | | | | | Code cleanup Description: Clean up ID->name code: - Reformat to better match library coding standard - Changed several algorithms to be more efficient - Integrated into library more smoothly Platforms tested: eirene w/FORTRAN & C++ arabica w/FORTRAN modi4 w/FORTRAN & parallel sleipnir
* [svn-r5929] Pedro Vicente Nunes2002-09-181-0/+8
| | | | | | | | | | | | | | Purpose: bug fix Description: memory leak regarding the ID to name buffer Solution: added a new function H5G_free_ent_name that is called on several places of the library Platforms tested: windows 2000 linux, with cpp solaris, with fortran, cpp irix64, with parallel, fortran
* [svn-r5904] Pedro Vicente Nunes2002-08-281-1/+23
| | | | | | | | | | | | | | | | | | | Purpose: Added 'ID to name' support Description: There is a new API function H5Iget_name Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t which has 2 new fields 'name' and 'old_name' A new private function was introduced H5G_ent_copy, that does a deep copy between 2 symbol table entries The test file is getname.c Platforms tested: windows 2000, Linux, Solaris
* [svn-r5879] Raymond Lu2002-08-201-6/+7
| | | | | | | | | Purpose: Design for compact dataset Description: Compact dataset is stored in the header message for dataset layout. Platforms tested: arabica, eirene.
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-9/+6
| | | | | | | | | | | | | | | | Code cleanup Description: Combined H5P_isa_class and H5I_object functionality into a new internal H5P API function: H5P_object_verify, which checks that a property list is the appropriate class and then returns the property list object associated with the property list ID. This reduces the source code by about 200 LOC and trims the library binary some more. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5867] Purpose:Quincey Koziol2002-08-091-3/+12
| | | | | | | | | | | | | Code cleanup Description: Changed the last HRETURN* statements in the FUNC_ENTER macros into HGOTO* macros, which reduces the size of the library binary in certain configurations by another 10% Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel, IRIX64 6.5 (modi4) serial & parallel
* [svn-r5866] Purpose:Quincey Koziol2002-08-091-4/+4
| | | | | | | | | | Code cleanup Description: Cleaned up a few warnings from compiling with --disable-hsizet on Linux Platforms tested: Linux 2.2.x (eirene)
* [svn-r5842] Purpose:Quincey Koziol2002-08-081-206/+211
| | | | | | | | | | | | | | | | Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.
* [svn-r5840] Purpose:Quincey Koziol2002-07-311-15/+13
| | | | | | | | | | | | | | Code cleanup Description: Created a new H5I function which combined the some of the functionality of H5I_get_type and H5I_object: H5I_object_verify. Using this new function in the library trims another ~200 lines of code off the library and makes the resulting binaries smaller and faster also. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5832] Purpose:Quincey Koziol2002-07-241-7/+7
| | | | | | | | | | Code cleanup Description: Re-alphabetized header includes. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & C++
* [svn-r5828] Purpose:Quincey Koziol2002-07-231-1/+4
| | | | | | | | | | Code cleanup Description: Make the sieve buffer managed by the free-list code. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5799] Purpose:Quincey Koziol2002-07-151-2/+3
| | | | | | | | | | | | New feature. Description: Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but performs I/O directly with posix sec(2) I/O functions. This driver should _NOT_ be used if the file accessed is not on a parallel filesystem. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
* [svn-r5784] Purpose:Quincey Koziol2002-07-121-91/+100
| | | | | | | | | | | | | | | Bug fix. Description: "strong" file closing feature was re-using free'd memory for objects which were still open in the file. Solution: Used the "dmalloc" tools to determine where the memory was being re-used and re-arranged the code to avoid these cases. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5677] Purpose:Quincey Koziol2002-06-191-19/+2
| | | | | | | | | | | Code improvement Description: Some small code cleanups and took out the code the was turning off the metadata cache for parallel I/O (!) Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5562] Purpose:Quincey Koziol2002-06-101-2/+2
| | | | | | | | | | | Code cleanup Description: Allow H5FD_free to return successfully (but ignore) freeing objects with size 0. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5551] Purpose:Quincey Koziol2002-06-071-2/+2
| | | | | | | | | | | | Bug fix. Description: Added extra check to locations where metadata and "small data" blocks were being returned to the file's list of free space to avoid freeing 0-sized blocks. This should fix the problems in last night's daily tests. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5542] Purpose:Quincey Koziol2002-06-061-0/+31
| | | | | | | | | | | | | | | | | Code cleanup/bug fix Description: Unused space in the file was being "dropped on the floor" when the metadata or "small data" block was moved to a new location in the file and there was unused space in the old block. Solution: Put the space left in the allocation block into the free list of space for the file. This allows it to be [potentially] reused and sometimes allows the file to be smaller. Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5538] Purpose:Quincey Koziol2002-06-051-41/+99
| | | | | | | | | | | | | | | Code improvement. Description: Added boot block and driver info block checksumming feature to the shared file information. This prevents these blocks from being written out multiple times when they haven't changed. This reduces the number of I/O operations which hit the disk for my test program from 15 to 14 (i.e. from 393 to 14, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5536] Purpose:Quincey Koziol2002-06-051-1/+8
| | | | | | | | | | | | | | | | | 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-r5471] Purpose:Quincey Koziol2002-05-291-29/+33
| | | | | | | | | | | | | | | | Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.
* [svn-r5467] Purpose:Quincey Koziol2002-05-281-15/+30
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: eliminating the compiler warnings in Windows Solution: I am eliminating the compiler warnings in Windows. the last 2 were: 1) if((oid_list = H5MM_malloc(oid_count*sizeof(hid_t)))==NULL) HGOTO_ERROR(H5E_RESOURCE, H5E_NOSPACE, NULL, "memory allocation failed"); D:\disk_w\hdf5\src\H5F.c(2590) : warning C4047: '=' : 'int ' differs in levels of indirection from 'void *' on the HGOTO_ERROR call , I replaced the NULL with FAIL 2) *((float*)d) = *((double*)s); D:\disk_w\hdf5\src\H5Tconv.c(6426) : warning C4244: '=' : conversion from 'double ' to 'float ', possible loss of data I added the type cast *((float*)d) = (float) *((double*)s); we have now 0 errors 0 warnings on Windows ! Platforms tested: w2000, linux
* [svn-r5440] Purpose:Quincey Koziol2002-05-201-15/+12
| | | | | | | | | | | New feature Description: Add 'closing' parameter to H5FDflush and VFL "flush" functions, per http://hdf.ncsa.uiuc.edu/RFC/VFLFlush/VFLFlush.html Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5414] Purpose:Quincey Koziol2002-05-141-0/+8
| | | | | | | | | | | | | | | Bug Fix Description: When H5Freopen is called, the file to reopen's 'intent' (read/write permissions, etc) is not being copied to the new file's 'intent' information. Solution: Copy it. :-) Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5408] Purpose:Quincey Koziol2002-05-131-0/+6
| | | | | | | | | | | | | | | Performance enhancement Description: Doing an MPI_File_sync() just before a file is closed causing a large performance loss. Solution: Add flag to MPI file driver to avoid performance the MPI_File_sync() when the flag is set before a call to H5F_flush(). Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5406] Purpose:Quincey Koziol2002-05-131-120/+121
| | | | | | | | | | Code cleanup Description: Restructure H5F_close code to use just one H5F_flush call. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5403] Purpose:Quincey Koziol2002-05-131-17/+11
| | | | | | | | | | Back out changes. Description: Back out changes to VFL 'flush' API function, pending review. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5393] Purpose:Quincey Koziol2002-05-101-11/+17
| | | | | | | | | | | | | | | | | | | | | | New Feature Description: The VFL flush function is called immediately before a file is closed. This can cause duplicate syncronization actions to occur, if the VFL close function also performs them. Solution: Added 'closing' parameter to VFL 'flush' operation. This allows the VFL flush function to bypass operations that will be duplicated within the VFL close function. Additionally, use the 'closing' parameter to bypass calls to MPI_File_sync() when set. Since MPI_File_close() also syncronizes the file, this avoids the terrible performance hit taken when calling MPI_File_sync() as the file is closing. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5390] Purpose:Quincey Koziol2002-05-101-8/+0
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: The parallel I/O file driver is optimized to only write metadata with one process (and broadcast the results to the other processes). This is currently enabled by a separate call to H5FD_mpio_tas_allsame() before each metadata write to the file. This can easily lead to problems where the prelude function call is omitted before the actual write code or, in a threaded environment, lead to race condititions where the value set is reset before being used. Solution: Since we only want to write metadata from one process, key off of the 'type' parameter (which has information about whether the data being written it metadata or raw data) to H5FD_mpio_write() as the method for determining whether to only write from one process or not. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5278] Purpose:Albert Cheng2002-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | Migrate from configure macros of XYZ_ABC to H5_XYZ_ABC Description: configure generates many macros definitions on the fly and were stored in src/H5config.h which is included by H5public.h. But other software that uses hdf5 may also run their own configure. There can be a clash in macro name space. We decided awhile ago to prepend all generated macros with "H5_" to avoid conflicts. The process has started and this commit completes it (at least attempt to). Solution: Many macros symbols (e.g. SIZEOF_xxx and HAVE_xxx were changed to H5_SIZEOF_xxx and H5_HAVE_xxx). Then H5private.h no longer includes H5config.h. This cuts H5config.h away from HDF5 source code. Pending issues: The module of fortran and pablo are to be resolved in a different commit. Platforms tested: eirene (parallel), arabica (solaris 7 --enable-fortran, --enable-cxx)
* [svn-r5152] Purpose:Quincey Koziol2002-04-091-1/+1
| | | | | | | | | | | | | | | New Feature Description: Added new H5Dfill() routine to fill the elements in a selection for a memory buffer with a fill value. This is a user API wrapper around some internal routines which were needed for the fill-value modifications from Raymond as well as Pedro's code for reducing the size of a chunked dataset. Platforms tested: FreeBSD 4.5 (sleipnir) [and IRIX64 6.5 (modi4) in parallel, in a few minutes]
* [svn-r5096] Purpose:Quincey Koziol2002-03-271-1/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: ----------------------------------------------------------------------
* [svn-r4867] Purpose:Quincey Koziol2002-01-271-4/+11
| | | | | | | | Code cleanup Description: Added some more assertions to help debug in the future... Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4757] Purpose:Albert Cheng2001-12-301-4/+0
| | | | | | | | | | | | | | | | | | Removing the DPSS (gridstorage) driver source code. Description: The DPSS (using Grid-Storage) driver is retired. Removed the configure option with-gridstorage from configure.in. Cvs remove the following files ./src/H5FDdpss.c ./src/H5FDdpss.h ./test/dpss_read.c ./test/dpss_write.c Regenerated Dependencies files (some had to be hand-edited since 'make depend' did not cover them.) Removed reference to DPSS Virtual file driver from H5F.c. Platforms tested: modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
* [svn-r4706] Purpose:Quincey Koziol2001-12-121-6/+10
| | | | | | | | | | | | Code cleanup Description: Tweaked internal error handling macros to reduce the size of the library's object code by about 10-20%. Also cleaned up some compiler warnings... Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4696] Raymond Lu2001-12-111-62/+443
| | | | | | | | | | | | | | | | | 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
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4622] Purpose:Quincey Koziol2001-11-201-620/+471
| | | | | | | | | | | Code cleanup Description: Be more careful when starting up and shutting down APIs, only initialize variables which are actually shut down already. Get rid of IDs from internal function calls Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4590] Purpose:Quincey Koziol2001-11-041-3/+3
| | | | | | | | | Code cleanup Description: Fix a bunch of warnings and also make the linux compilers happy with some casts. Platforms tested: Linux 2.2 (eirene)

* [svn-r4548] Purpose:Quincey Koziol2001-10-161-13/+17
| | | | | | | | | | | Code cleanup. Description: Fix a few compiler warnings from the file creation property list -> generic property list conversion. Also change a hard-wired value (8) for the number of B-tree key values to a value that uses the enum's generated by the compiler. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4543] Raymond Lu2001-10-151-126/+334
| | | | | | | Purpose: Changed the file creation property list to the new generic property list. Platform tested: IRIX64, SunOS5.7, FreeBSD
* [svn-r4473] Purpose:Quincey Koziol2001-09-251-1/+1
| | | | | | | | | | | | | | | | | | | | | Code cleanup for better compatibility with C++ compilers Description: C++ compilers are choking on our C code, for various reasons: we used our UNUSED macro incorrectly when referring to pointer types we used various C++ keywords as variables, etc. we incremented enum's with the ++ operator. Solution: Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid, template) Fixed usage of UNUSED macro from this: char UNUSED *c to this: char * UNUSED c Switched the enums from x++ to x=x+1 Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-24/+24
| | | | | | | | | | | | | | | | | | | | | | 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)
