* [svn-r9552] Purpose:Quincey Koziol2004-11-191-10/+31
| | | | | | | | | | | | | | | | | Code optimization Description: Avoid making as many copies of attribute information. Also, be smarter about which properties we've seen before when copying and closing property lists. Fix memory leak of attribute data structures. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r8781] James Laird2004-07-011-1/+0
| | | | | | | | | | | | | | | | Purpose: HDF5 now supports SZIP with no encoder. Description: SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled. Solution: Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC. Platforms tested: Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++) Misc. update:

| | | | | | | | | | | | | Code cleanup & small bug fix Description: Regenerate dependency files Add htri_t as separate type from hbool_t for code tracing purposes. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-10/+9
| | | | | | | | | | | | | | | 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-r8488] Purpose:Leon Arber2004-05-061-0/+1
| | | | | | | | | | | | | | | | | | | Bug fix. Description: Fixed handling of trivial data transform expressions (like 5/3 + 3) and some data coversion fixes. Also added more tests to dtransform.c Solution: Added some more checks in the H5Z_xform_reduce_tree function to see if perhaps the transform expression is complicated and is a non-trivial reduction. Added tests for data conversion to dtransform as well as tests for a trivial data transform expression. Platforms tested: h5committest'ed, except used arabica instead of sol and didn't do on copper b/c no logon there. Problem noted with mtime test...doesn't appear to be related to anything having to do with data transforms.
* [svn-r8287] Purpose:Quincey Koziol2004-03-301-1/+1
| | | | | | | | | | | | | | Bug fix/code cleanup Description: Copy Robb's feature in SSlib that checks that the name of the function used in the FUNC_ENTER macro is actually the name of function. Fixed a bunch of typos & copy-n-pasto's for functions with incorrect names. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8038] Purpose:Quincey Koziol2004-01-081-48/+214
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When two property lists are compared, the H5Pequal routine was just comparing the raw information for the property values. This causes problems when the raw information contains pointers to other information. Solution: Allow a 'compare' callback to be registered for properties, so that a user application get perform the comparison itself, allowing for "deep" compares of the property value. This was exported to the H5Pregister & H5Pinsert routines in the development branch, but not the release branch. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7930] Purpose:Quincey Koziol2003-12-111-4/+3
| | | | | | | | | | | | Bug fix/code cleanup Description: Make H5Pclose_class() decrement the ID's reference count to close a generic property class ID, which allows the new H5I routines to work correctly. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-37/+37
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)
* [svn-r7373] Purpose:Quincey Koziol2003-08-151-7/+2
| | | | | | | | | | | | Code cleanup Description: Cleanup H5Pclose code and also switch a few internal users of H5Pclose to use H5I_dec_ref instead. Platforms tested: FreeBSD 4.8 (sleipnir) too small for h5committest

* [svn-r6952] Purpose:Quincey Koziol2003-06-041-96/+6
| | | | | | | | | | | | | Code cleanup Description: Move testing routines into their own module, to avoid linking them into user's applications needlessly. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ FreeBSD 4.8 (sleipnir) w/parallel h5committested
* [svn-r6878] Purpose:Quincey Koziol2003-05-151-46/+2
| | | | | | | | | | | Code cleanup Description: Limit the scope on more function prototypes/macros/typedefs. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6269] Purpose:Quincey Koziol2003-01-131-4/+39
| | | | | | | | | | | | | Code cleanup Description: Various code cleanups to allow the development branch to be compiled with a C++ compiler (i.e. CC=g++ ) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) C++
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-77/+77
| | | | | | | | | | | | 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 Koziol2003-01-091-24/+43

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [svn-r6024] Purpose:Bill Wendling2002-10-231-19/+18
| | | | | | | | | Feature Add Description: Moved some functions from having only module scope to having public scope, but only available in the HDF5 internals (not public APIs). Platforms tested: Eirene, Arabica, Modi4
* [svn-r5992] Purpose:Quincey Koziol2002-10-141-23/+13
| | | | | | | | | | | | | | | | | Bug fix Description: Generic property classes where incorrectly reference counting their users, in certain cases, causing a memory leak. Solution: Cleanup reference counting code & unify in H5P_access_class() Platforms tested: FreeBSD 4.6 (sleipnir) w and w/o parallel Linux 2.2.x (eirene) w/FORTRAN & C++ Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/FORTRAN & parallel
* [svn-r5968] Purpose:Quincey Koziol2002-10-091-2/+2
| | | | | | | | | Code cleanup Description: Change new H5P_get_class_path and H5P_open_class_path functions to be non- static and put prototypes in H5Pprivate.h Platforms tested: FreeBSD 4.6 (sleipnir) (no triple-check necessary)
* [svn-r5964] Purpose:Quincey Koziol2002-10-081-32/+155
| | | | | | | | | | | | | | | Internal feature. Description: To complement the "get the class's path" functionality, there needs to be a way to open a generic property class with a path. Solution: Implement the "open a class by path" functionality. Also, add internal testing routines. Platforms tested: FreeBSD 4.6 (sleipnir) (too small for triple testing)
* [svn-r5963] Purpose:Quincey Koziol2002-10-081-7/+115
| | | | | | | | | | | | | | | | | | | | New internal feature. Description: Need some way to determine the "full path" for a generic property class, i.e. where is this class in the class hierarchy, in relation to its parent class, etc. Solution: Added an internal function "H5P_get_class_path" and a testing function "H5Pget_class_path_test" that builds the full path of a generic property class back to the top of its class hierarchy. This implementation uses '/' characters to delimit the components of the class path, but no special cases are currently supported for having a '/' character as part of the actual class name. Should this become an issue, code to support (and test) it will need to be added. Platforms tested: FreeBSD 4.6 (sleipnir) (not major enough to justify triple-test)
* [svn-r5962] Purpose:Quincey Koziol2002-10-071-13/+73
| | | | | | | | | | | | Bug fix Description: H5Pequal's algorithm for comparing property lists wasn't allowing property lists that are equal but had the properties inserted in a different order in the list's hash table. Solution: Re-did the algorithm a bit to compare the properties better. Platforms tested: FreeBSD 4.6 (sleipnir) (minor enough to not need triple testing)
* [svn-r5872] Purpose:Quincey Koziol2002-08-121-3676/+0
| | | | | | | | | | | | Code cleanup Description: Move get/set routines for each type of property list (file creation, dataset creation, file access and dataset transfer) into their own source code module. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-277/+108
| | | | | | | | | | | | | | | | 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 Koziol2002-08-091-2/+15
| | | | | | | | | | | | | 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-r5842] Purpose:Quincey Koziol2002-08-081-161/+92
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-23/+23
| | | | | | | | | | | | | | 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-r5652] Purpose:Quincey Koziol2002-06-171-3/+3
| | | | | | | | | | | | Code cleanup Description: Use dataset transfer property list to hold information about the MPI types for the current transfer, instead of setting pseudo-global variables in the file's struct. Platforms tested: Linux 2.2.x (eirene) w/parallel & IRIX64 6.5 (modi4) w/parallel & FORTRAN
* [svn-r5563] Purpose:Quincey Koziol2002-06-101-2/+0
| | | | | | | | | | | New Feature Description: Add H5P[set|get]_small_data_block_size API function, per our discussions at last week's HDF5 meeting. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5536] Purpose:Quincey Koziol2002-06-051-112/+100
| | | | | | | | | | | | | | | | | 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 Koziol2002-05-291-104/+104
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-55/+83
| | | | | | | | | | | | | | | | | | | | | | | | 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-r5433] Purpose:Quincey Koziol2002-05-171-1/+1
| | | | | | | Code cleanup Description: Cleaned up the function header comment for H5Pset_fill_time.
* [svn-r5310] Purpose:Quincey Koziol2002-05-011-0/+5
| | | | | | | | | | Code cleanup Description: Update the API tracing information Platforms tested: Linux 2.2 (eirene) with gcc 2.95.2 and Solaris 2.6 (baldric) with gcc 2.8.1
* [svn-r5195] Purpose:Quincey Koziol2002-04-171-3/+2
| | | | | | | | | | | | | | 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-r5170] Raymond Lu2002-04-111-24/+302
| | | | | | | | | | | Purpose: New feature Description: Fill-value's behaviors for contiguous dataset have been redefined. Basicly, dataset won't allocate space until it's necessary. Full details are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment. Platforms tested: Linux 2.2.
* [svn-r4978] Purpose:Quincey Koziol2002-02-171-3/+0
| | | | | | | | Code cleanup Description: Cleanup compiler warnings found by the SGI compiler and gcc 3.0 Platforms tested: FreeBSD 4.5 w/gcc 3.0 (hack) && IRIX64 (modi4)
* [svn-r4920] Purpose:Quincey Koziol2002-02-071-27/+2
| | | | | | | | | Bug fix Description: Correct inefficient property copying when using derived property list classes. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4904] Purpose:Quincey Koziol2002-02-061-16/+49
| | | | | | | | | | | | | | | | | | Bug fix Description: Generic property classes derived from an existing class were not having the parent class's properties copied into the new class. Additionally, derived classes were not being detected correctly. Solution: Copied properties from parent class into derived class. Modified H5P_isa_class_real() to walk back up the chain of parent classes to proper detect derived classes. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4839] Purpose:Quincey Koziol2002-01-161-7/+0
| | | | | | | | | | Bug fix Description: Missed CVS conflict in ifdef'd code Solution: Editted to remove CVS conflicted code. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4706] Purpose:Quincey Koziol2001-12-121-1/+1
| | | | | | | | | | | | 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 Lu2001-12-111-0/+78
| | | | | | | | | | | | | | | | | 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-r4680] Purpose:Quincey Koziol2001-12-061-1/+3
| | | | | | | | | | | | | Code cleanup Description: Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the library. Solution: Removed H5P(g|s)et_hyper_cache API functions, except when backward compatibility is turned on. When backward compatibility is turned on, the property is defined by the library, but unused internally. Platforms tested: FreeBSD 4.4 (sleipnir)

* [svn-r4676] Purpose:Quincey Koziol2001-12-051-0/+114
| | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_buffer's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_buffer implementation and testing to allow v1.4.x users to continue to use their source code without modification. These changes are for everything except the FORTRAN wrappers - I spoke with Elena and she will make the FORTRAN wrapper changes. Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_sieve_buf_size's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_sieve_buf_size implementation and testing to allow v1.4.x users to continue to use their source code without modification. There are no C++ or FORTRAN wrappers for these functions. There are also no regression tests for these functions... :-( Platforms tested: FreeBSD 4.4 (hawkwind)
