* [svn-r5536] Purpose:Quincey Koziol2002-06-051-0/+1
| | | | | | | | | | | | | | | | | 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 Koziol2002-05-291-17/+17
| | | | | | | | | | | | | | | | 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-r5440] Purpose:Quincey Koziol2002-05-201-3/+3
| | | | | | | | | | | 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-r5436] Pedro Vicente Nunes2002-05-181-1/+0
| | | | | | | | | Purpose: code clean up Description: removed some debugging comments regading the code warrior port Platforms tested: w2000
* [svn-r5422] Description:Albert Cheng2002-05-141-1/+1
| | | | | | | Corrected typos in the FUNC_ENTER macros of H5FD_sec2_flush and H5FD_log_flush. Platforms tested: modi4 (just tested it compiled fine.)
* [svn-r5403] Purpose:Quincey Koziol2002-05-131-3/+3
| | | | | | | | | | Back out changes. Description: Back out changes to VFL 'flush' API function, pending review. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5393] Purpose:Quincey Koziol2002-05-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | 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-r5261] Purpose:Quincey Koziol2002-04-251-3/+0
| | | | | | | | | | Code cleanup Description: Remove more debugging printf's that were ifdef'd out. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5219] Purpose:Quincey Koziol2002-04-221-1/+1
| | | | | | | | | | Code cleanup Description: Clean up warnings from gcc 3.1 Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5205] Purpose:Albert Cheng2002-04-191-3/+1
| | | | | | | | | | | | | | Code cleanup Description: Platform dependent code related to the struct stat and fstat calls polluted source codes. Hard to maintain. Solution: Platform dependent code are moved to H5private.h and then internal code can #include H5private.h. Repeat those macro definition for the stdio and multi drivers since they area examples for writing a virtual file driver. They must not use any internal code. Platforms tested: eirene (parallel), modi4 (serial including gass driver.)
* [svn-r5101] MuQun Yang2002-03-271-1/+3
| | | | | | | | | | | | | | | Purpose: fix a windows bug Description: 1. To create a >4GB file, fstati64 has to be used instead of fstat. change fstat to fstati64 for WIN32 macroes. Some discussions are going on the general issue on how to better handle with WIN32 or other similar platform. This check-in is just a reminder not to forget the windows bug. 2. erase a WIN32 macro(include winsock2.h) at h5detect.c. It is not a problem now. Solution: use fstati64 instead of fstat for win32. Platforms tested: windows2000(confirmed at linux machine eirene)
* [svn-r4696] Raymond Lu2001-12-111-0/+1
| | | | | | | | | | | | | | | | | 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-r4673] Purpose:Quincey Koziol2001-12-051-0/+48
| | | | | | | | | | | | | | Backward Compatibility Fix Description: H5Pset_fapl_log's parameters have changed from a simple "verbosity" level to bit-masked flags to enable various behaviors. Solution: Added in v1.4 compat stuff, on the unlikely chance that others are actually using this code in some production way. There are no C++ or FORTRAN wrappers for this call. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4666] Purpose:Quincey Koziol2001-12-041-3/+5
| | | | | | | | | | | Bug fix Description: Missing a statement for an else branch when HAVE_GETTIMEOFDAY was defined, which caused most machines to fail compiling. Solution: Re-arranged if/else statement to eliminate problem. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4665] Purpose:Quincey Koziol2001-12-031-112/+161
| | | | | | | | | Code cleanup Description: Changed the logging file driver to use bitmasked flags for features to enable, instead of using a verbosity level. Platforms tested: Solaris 2.6 (baldric)
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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-r4620] Purpose:Quincey Koziol2001-11-201-11/+12
| | | | | | | | | 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 Lu2001-10-251-2/+8
| | | | | | | Purpose: Followup file access property list changes. Platforms tested: IRIX64, SunOS 5.7, 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-r4406] Purpose:Quincey Koziol2001-08-221-21/+93
| | | | | | | | Tweaks Description: Improved the readability of the output and added some time information. Platforms tested: Solaris 2.6 (baldric)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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-r4232] Purpose:Quincey Koziol2001-07-171-0/+9
| | | | | | | | | | | | | | | | | Bug fix. Description: On some systems (linux when not using gcc) 'dev_t' is not actually a scalar variable. This causes the code which compares dev_t's in the file drivers to not compile. Also the H5_inline flag was not being set correctly in the H5private.h file. Solution: Set the H5_inline flag to '' (i.e. define it, but don't assign it a value) if it is not currently defined. Use DEV_T_IS_SCALAR flag from configure to correctly compare dev_t's using memcmp instead of a scalar flag. Platforms tested: FreeBSD 4.3 (hawkwind), Linux 2.4.2 (chiba city cluster at Argonne)
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-17/+14
| | | | | | | | | 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-r4088] Purpose:Quincey Koziol2001-06-291-1/+30
| | | | | | | | | | | | Code cleanup Description: Recent CodeWarrior patches have broken the Unix builds and moved code around in non-portable ways. Solution: Patched things back up to try to accomodate CodeWarrior and still let the Unix builds work correctly. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r4083] Pedro Vicente Nunes2001-06-291-30/+1
| | | | | | | | | | | | | | code warrior support and some clean up the macros file_seek and file_offset_t that were repeated over sevral files were put only in H5private.h H5private .h was updated for win32 vthe Description: Solution: Platforms tested:
* [svn-r4012] Purpose:Quincey Koziol2001-06-181-1/+1
| | | | | | | | Clean up compiler warnings. Description: Just code neatening mostly, some casts, etc. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r4010] Purpose:Quincey Koziol2001-06-161-0/+30
| | | | | | | | | | | | | Bug Fix Description: uint64_t type was accidentally taken out and was causing tests on DEC UNIX to fail. Solution: Brought back uint64_t type. Also cleaned up some comments and moved the sec2 specific macros back into the sec2 (and log) driver. Platforms tested: DEC UNIX (gondolin)

* [svn-r3963] Purpose:Quincey Koziol2001-06-051-1/+9
| | | | | | | | | Small code addition Description: Addition logging of seeks during read operations (writes were already logging seeks). Also added a few asserts to check memory allocations... Platforms tested: Solaris 2.6 (baldric)
* [svn-r3885] Purpose:Quincey Koziol2001-05-021-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | Document bug fix Description: IMPORTANT! IMPORTANT! IMPORTANT! A case where metadata in a file could get corrupted in certain unusual sitations was detected and fixed. In certain circumstances, metadata could get cached in the raw data cache, and if that particular piece of metadata was updated on disk while incorrectly cached, the new metadata would get overwritten with the stale metadata from the raw data cache when it was flushed out. Additionally, I've patched up the raw data cache to be smarter about how much it caches and how much I/O it triggers, leading to some speedups. Solution: Changed the raw data I/O routines which perform caching to require a parameter with the size of the dataset being accessed and limited the cache to no more than that many bytes. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-10/+10
| | | | | | | | | | | | | | | | | | 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-r3274] MuQun Yang2001-01-121-3/+0
| | | | | | | | | | Purpose: Arrange codes for avoiding windows warnings Description: Solution: put windows including header files into H5private.h Platforms tested: win 2000, confirmed at eirene
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-13/+17
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3218] ./hdf5/src/H5FDlog.cRobb Matzke2000-12-291-6/+7
| | | | | | | 2000-12-29 08:55:06 Robb Matzke <matzke@llnl.gov> * H5FD_log_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-r3027] Purpose:Quincey Koziol2000-11-291-1/+1
| | | | | | | | | | | Bug fix Description: "UNUSED" macro was in wrong place for older versions of gcc Solution: Moved the "UNUSED" macro to the right of the H5FD_t type declaration and the compiler was happy... Platforms tested: Solaris X86 2.5 (hatteras)
* [svn-r3025] MuQun Yang2000-11-291-0/+4
| | | | | | | | | | | | | | Purpose: fix a bug Description: add <windows.h> for WIN32 Solution: Add the following lines at the beginning of the file #ifdef WIN32 #include <windows.h> #endif Platforms tested: NT4.0,5.0, and LINUX
* [svn-r3008] Purpose:Quincey Koziol2000-11-281-1/+1
| | | | | | | | | | | | | | Code cleanup Description: Several places in the code were using -2 as a default value for various features. However, when a default value is returned from a function that is supposed to return negative on failure, it was causing confusion and extra work for users to check for the special value. Solution: Replaced hard-coded -2 values in the code with symbolic names, then changed symbolic names to 0 instead of -2. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r2866] Purpose:Quincey Koziol2000-11-111-1/+1
| | | | | | | | Code cleanup Description: Found more "Have_foo" usage and converted them to "H5_HAVE_foo" Platforms tested: FreeBSD 4.1.1 (hawkwind)
* [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-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-r2652] Purpose:Quincey Koziol2000-10-101-2/+3
| | | | | | | | | | | | | | | 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)
* [svn-r2611] Purpose:Quincey Koziol2000-09-281-1/+1
| | | | | | | | | | | | | 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)
* [svn-r2601] Purpose:Quincey Koziol2000-09-271-5/+2
| | | | | | | | | | | | Bug Fix Description: The core and log VFL drivers were leaking small amounts of memory when they were used. Solution: Free the appropriate memory block (for the core driver) and don't allocate a block (for the log driver). Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2600] Purpose:Quincey Koziol2000-09-261-0/+1
| | | | | | | | | | | Implemented new feature Description: Added data sieve buffering code to raw I/O data path. This is enabled for all the VFL drivers except the mpio & core drivers. Also added two new API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and H5Pget_sieve_buf_size(). Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2579] Purpose:Quincey Koziol2000-09-191-2/+1
