* [svn-r6266] Purpose:Quincey Koziol2003-01-101-49/+49
| | | | | | | | | | | | 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-r6255] Purpose:Quincey Koziol2003-01-091-5/+5
| | | | | | | | | | Code cleanup Description: Clean up a few more warnings and update dependencies. Platforms tested: Linux 2.2.18smp (eirene) serial & parallel
* [svn-r6252] Purpose:Quincey Koziol2003-01-091-549/+547
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

* [svn-r6145] Raymond Lu2002-12-021-1/+11
| | | | | | | | | | Purpose: New feature to H5Dget_offset Description: If user block is set, H5Dget_offset should be able to return the absolute offset from the beginning of file. Platforms tested: eirene, arabica
* [svn-r6072] Purpose:Bill Wendling2002-11-111-11/+1
| | | | | | | | | | Code Movement Description: Moved definition of the H5D_t data structure into the H5Dprivate.h header file. With the FPHDF5 stuff, we need access to this data structure. Platforms tested: Eirene...change small, so no need for all three tests.
* [svn-r6063] Purpose:Quincey Koziol2002-11-071-5/+7
| | | | | | | | | | | Code cleanup Description: Cleaned up some error values that were incorrect, added some assertions and refactored the integer & floating-point native conversions some. Platforms tested: FreeBSD 4.7 (sleipnir), too small for h5committest
* [svn-r6062] Raymond Lu2002-11-071-0/+82
| | | | | | | | | | | | Purpose: New function. Description: H5Dget_offset returns the offset of a dataset's data relative to the beginning of a file. Platforms tested: arabica(simple function, one test should be enough.) Misc. update: RELEASE.txt
* [svn-r6057] Purpose:Bill Wendling2002-11-051-99/+244
| | | | | | | | | | | | | | | | | | | | | | | New Feature. Support for new FPHDF5 Feature Description: More support for the FPHDF5 feature. This splits the H5D_create function into separate parts which update the metadata cache. It was necessary to split apart the H5O_create function to do a similar thing since it would allocate real space on the hard disk. I'm checking this up now so that I don't get too far away from what the CVS repository has and so that others may look at the code and retch^H^H^H^H^Hmarvel at it. If there are any comments, send them my way. There is one outstanding issue, though. I need to use non-API functions in the FPHDF5 stuff. I'm using some APIs right now and should migrate to using others. At the moment, I'm putting that on the back burner until I'm more along in the implementation. Platforms tested: Arabica (C++) Eirene (Parallel) Modi4 (Parallel)
* [svn-r6030] Purpose:Bill Wendling2002-10-231-403/+11
| | | | | | | | | | Another Oops Description: I accidentally checked in the H5D.c module when I shouldn't have. Solution: Rolled back to 1.281 version Platforms tested: Linux
* [svn-r6029] Purpose:Bill Wendling2002-10-231-11/+403
| | | | | | | | | | | | 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-r5929] Pedro Vicente Nunes2002-09-181-0/+7
| | | | | | | | | | | | | | 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-r5926] Purpose:Quincey Koziol2002-09-131-38/+38

* [svn-r5894] Purpose:Quincey Koziol2002-08-271-241/+327
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* [svn-r5884] Purpose:Quincey Koziol2002-08-211-48/+53
| | | | | | | | | | | | Bug fix/Code cleanup Description: Clean up memory leak in fill value code Also rearrange logic of code a bit Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5882] Raymond Lu2002-08-201-74/+72
| | | | | | | | | | Purpose: Bug fix. Description: In H5D_init_storage, contiguous dataset is not initialized properly when fill value is library default. Platforms tested: eirene
* [svn-r5879] Raymond Lu2002-08-201-47/+179
| | | | | | | | | Purpose: Design for compact dataset Description: Compact dataset is stored in the header message for dataset layout. Platforms tested: arabica, eirene.
* [svn-r5875] Purpose:Quincey Koziol2002-08-141-3/+10
| | | | | | | | | | | | | | 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-r5871] Purpose:Quincey Koziol2002-08-121-28/+26
| | | | | | | | | | | | | | | | 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/+13
| | | | | | | | | | | | | 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 Koziol2002-08-091-1/+1
| | | | | | | | | | 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 Koziol2002-08-081-13/+24
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-258/+220
| | | | | | | | | | | | | | 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-r5839] Purpose:Quincey Koziol2002-07-311-31/+31
| | | | | | | | | | | | | | | Code cleanup Description: Move operations on each type of selection into the source code file for each selection type (all->H5Sall.c, hyperslab->H5Shyper.c, etc.) Remove central H5S_select_<foo> operations, instead calling the operations through function pointers in each selection (a much more object-oriented approach). Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5834] Purpose:Quincey Koziol2002-07-241-37/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large code cleanup/re-write Description: This is phase 1 of the data I/O re-architecture, with the following changes: - Changed the selection drivers to not actually do any I/O, they only generate the sequences of offset/length pairs needed for the I/O (or memory access, in the case of iterating or filling a selection in a memory buffer) - Wrote more abstract I/O routines which get the sequence of offset/ length pairs for each selection and access perform the I/O or memory access. Benefits of this change include: - Removed ~3400 lines of quite redundant code, with corresponding reduction in the size of library binary. - Any selection can now directly access memory when performing I/O, if no type conversions are required, instead of just "regular" hyperslab and 'all' selections, which speeds up I/O. - Sped up I/O for hyperslab selections which have contiguous lower dimensions by "flattening" them out into lesser dimensional objects for the I/O. No file format or API changes were necessary for this change. The next phase will be to create a "selection driver" for each type of selection, allowing each type of selection to directly call certain methods that only apply to that type of selection, instead of passing through dozens of functions which have switch statements to call the appropriate method for each selection type. This will also reduce the amount of code in the library and speed things up a bit more. Phase 3 will involve generating an MPI datatype for all types of selections, instead of only "regular" hyperslab and 'all' selections. This will allow collective parallel I/O for all I/O operations which don't require type conversions. It will also open up the door for allowing collective I/O on datasets which require type conversion. Phase 4 will involve changing the access pattern to deal with chunked datasets in a more optimal way (in serial). Phase 5 will deal with accessing chunked datasets more optimally for collective parallel I/O operations. Platforms tested: FreeBSD 4.6 (sleipnir) w/ parallel & C++ and IRIX64 6.5 (modi4) w/parallel
* [svn-r5799] Purpose:Quincey Koziol2002-07-151-18/+20
| | | | | | | | | | | | 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-r5764] Raymond Lu2002-07-031-2/+12
| | | | | | | | | | | Purpose: Bug Fix. Description: VL type memory leak when data is overwritten. Solution: Free heap objects holding old data. Platforms tested: Linux 2.2(eirene), IRIX 6.5(paz).
* [svn-r5680] Purpose:Quincey Koziol2002-06-191-2/+2
| | | | | | | | | | | | | | | | | | | | New feature. Description: There is some discussion among the SAF team as to whether it is better to use MPI derived types for raw data transfers (thus needing a MPI_File_set_view() call), or whether it is better to use a sequence of low-level MPI types (i.e. MPI_BYTE) for the raw data transfer. Solution: Added an in internal flag to determine whether derived types are preferred (the default), or whether they should be avoided. An environment variable ("HDF5_MPI_PREFER_DERIVED_TYPES") can be set by users to control whether MPI types should be used or not. Set the environment variable to "0" (i.e.: 'setenv HDF5_MPI_PREFER_DERIVED_TYPES 0' to avoid using MPI derived types. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5677] Purpose:Quincey Koziol2002-06-191-26/+24
| | | | | | | | | | | 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-r5670] Purpose:Quincey Koziol2002-06-191-9/+0
| | | | | | | | | | | Code cleanup Description: Remove "COALESCE_READS" ifdefs, which were brought in by the DPSS VFL driver and are no longer used. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5586] Purpose:Quincey Koziol2002-06-111-7/+12
| | | | | | | | | | | | | | | | Bug Fix Description: H5Dcreate and H5Tcommit allow "empty" compound and enumerated types (i.e. ones with no members) to be stored in the file, but this causes an assertion failure and is somewhat vapid. Solution: Check the datatype "makes sense" before using it for H5Dcreate and H5Tcommit. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5545] Purpose:Quincey Koziol2002-06-061-4/+0
| | | | | | | | | | Code cleanup Description: Back out [apparently] unnecessary include of H5F package include files. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5530] Purpose:Bill Wendling2002-06-041-6/+12
| | | | | | | | | | | | | | | Code Cleanup Description: Removed some compiler warnings. Solution: In a few cases, NULL was being returned when a FAIL was supposed to be returned instead. There were some header files which needed to be included in a few of the sources. A couple of if-then statements had assignments in the conditional part. The compiler warned that they should have extra "()"s around them. Made the code check the values instead. Platforms tested: Linux (parallel) Modi4 (parallel)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-45/+48
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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)
* [svn-r5272] Purpose:Quincey Koziol2002-04-261-10/+10
| | | | | | | | | | | Bug fix Description: Move iterator initialization in H5D_read & H5D_write before any errors can occur. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5259] Purpose:Quincey Koziol2002-04-251-93/+38
| | | | | | | | | | | | | | | | 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)
* [svn-r5255] Purpose:Quincey Koziol2002-04-251-180/+41
| | | | | | | | | | | Code cleanup Description: Reduce gratuitous differences between H5D_write and H5D_read and also remove distracting debugging printf's that were ifdef'd out. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5219] Purpose:Quincey Koziol2002-04-221-1/+2
| | | | | | | | | | Code cleanup Description: Clean up warnings from gcc 3.1 Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5205] Purpose:Albert Cheng2002-04-191-0/+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-r5203] Purpose:Quincey Koziol2002-04-181-171/+171
| | | | | | | | | | Code cleanup Description: Re-indented new code to match coding style of rest of library. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5200] Purpose:Quincey Koziol2002-04-181-1/+1
| | | | | | | | | | Code Cleanup Description: Clean up compiler warnings from the last bunch of checkins Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5198] Purpose:Quincey Koziol2002-04-181-23/+18
| | | | | | | | | | | Code Cleanup Description: Remove "knowledge" about external file storage from H5D_init_storage and call H5F_seq_write instead, which handles things correctly. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5195] Purpose:Quincey Koziol2002-04-171-12/+3
| | | | | | | | | | | | | | Code cleanup Description: Got rid of the "H5T_BKG_TEMP" setting that was used internally to the library, since temporary background buffers are now handled by the individual conversion routines instead of in a global background buffer. No APIs were changed or affected by this. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5191] Purpose:Quincey Koziol2002-04-171-0/+1
| | | | | | | | | | | | | | | | | | | Bug fix Description: When several level deep nested compound & VL datatypes are used, the data in the nested compound datatypes is incorrectly sharing the same "background buffer", causing data corruption when the data is written to the file. Solution: Allocate a separate background buffer for each level of the nested types to convert. (Also allocate temporary background buffers for array datatypes, where this sort of problem could occur also) Added more regression tests to check for these errors. Platforms tested: FreeBSD 4.5 (sleipnir) & Solaris 2.6 (baldric)
