| | | | | | | | | | | | | Finish refactoring job on the library's property list class initialization code, so that the library determines the parent class dependencies at run-time, eliminating the need for developers to initialize the classes in a particular order. Also eliminates some more redundant code...

* [svn-r12842] Description:Quincey Koziol2006-11-021-1/+1
| | | | | | | | | | | | | | | | Refactor generic property list initialization code to put property list specific routines in property list modules, instead of scattered to the four winds. Also, introduce property list class initialization objects, to make adding new property list classes in the library easier. Fix daily test failure by using H5Pget_elink_prefix() API routine instead of looking at the "raw" generic property list information.

* [svn-r12452] Purpose:James Laird2006-07-051-0/+5
| | | | | | | | | | | | | | | | | | | | | | Feature Description: Revised Link APIs. Solution: New link APIs use H5L* H5*create_expand do not create links to the objects created; this must be done manually with H5Llink. Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy), and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query API (H5Lget_linkinfo instead of H5Gget_objinfo). All old APIs are still supported in H5Gdeprec.c . Platforms tested: sol, mir, copper Misc. update: Forgot to update MANIFEST and release docs. Will do after checkin.
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10958] Purpose:Quincey Koziol2005-06-201-2/+2
| | | | | | | | | | | | | New feature Description: Add group creation & access property lists, dataset access property lists and named datatype creation & access property lists. Currently have <foo>_extend() API names, which will need to be changed for the final release. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (heping)
* [svn-r8158] Purpose:Quincey Koziol2004-02-061-2/+0
| | | | | | | | | | | | | | | | | Code cleanup/optimization Description: Query property list values once, at the beginning of the I/O routines, instead of querying the property list values multiple (lots!) of times in lower level routines. Solution: Create "property list caches" for internal library queries of the property list values. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest
* [svn-r8038] Purpose:Quincey Koziol2004-01-081-2/+3
| | | | | | | | | | | | | | | | | | | | 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-r6878] Purpose:Quincey Koziol2003-05-151-18/+3

* [svn-r6252] Purpose:Quincey Koziol2003-01-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Wendling2002-10-231-0/+2
| | | | | | | | | 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-r5968] Purpose:Quincey Koziol2002-10-091-0/+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 Koziol2002-10-081-1/+5
| | | | | | | | | | | | | | | 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 Koziol2002-10-081-0/+1
| | | | | | | | | | | | | | | | | | | | 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-r5951] Raymond Lu2002-09-301-0/+4
| | | | | | | | | | | Purpose: New API functions Description: Added API functions to return pointer to low-level file handle (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list setting functions(H5Pset_family_offset and H5Pset_multi_type). Platforms tested: Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
* [svn-r5931] MuQun Yang2002-09-201-23/+23
| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-0/+1
| | | | | | | | | | | | | | | | 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-r5652] Purpose:Quincey Koziol2002-06-171-0/+6
| | | | | | | | | | | | 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-r5259] Purpose:Quincey Koziol2002-04-251-2/+2
| | | | | | | | | | | | | | | | 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-r5170] Raymond Lu2002-04-111-0/+2
| | | | | | | | | | | 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-r4626] Purpose:Quincey Koziol2001-11-201-77/+27
| | | | | | | | Code cleanup Description: Moved parts of the H5P stuff into the new H5Ppkg.h header file from here. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4584] Raymond Lu2001-11-021-9/+1
| | | | | | | | | Purpose: Switch from old property list to new generic property list. Description: Mainly changed H5Pcreat, H5Pclose, H5Pcopy. Platforms tested: IRIX64 6.5, FreeBSD, SunOS 5.7.
* [svn-r4573] Raymond Lu2001-10-251-6/+1
| | | | | | | Purpose: Switch mount property list to the new generic property list. Platforms tested: IRIX64 6.5, SunOS 5.7, FreeBSD.
* [svn-r4569] Raymond Lu2001-10-241-1/+1

* [svn-r4518] Purpose:Quincey Koziol2001-10-031-1/+1
| | | | | | | | Code cleanup Description: Clean up some small compiler warnings. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4517] Raymond Lu2001-10-031-1/+1
| | | | | | | | Purpose: Changed to the new generic property list for dataset creation property list. Platforms tested: Arabica, modi4 and Hawkwind
* [svn-r4482] Purpose:Quincey Koziol2001-09-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | Kludge Description: Since we're only about halfway through converting the internal use of property lists from the "old way" to the generic property lists, we turned off snapshots to avoid exposing lots of API changes to users, until the APIs settled down. Getting the snapshots rolling again seems to have become a priority, so some changes are going to have to be made now that were going to be postponed until we were completely finished with the conversion. This requires that the old API functions be able to deal with both the old and new property lists smoothly. Solution: Kludge together the property list code so that they can transparently handle dealing with both the old and new property lists Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4437] Purpose:Quincey Koziol2001-09-121-2/+2
| | | | | | | | | Adding Feature Description: Added new H5Pcopy_prop function to copy a property (value) from one property list or class to another. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-9/+9
| | | | | | | | | | | | | | | | | | | | | | 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-r4329] Purpose:Quincey Koziol2001-08-121-0/+1
| | | | | | | | | | | | | | Bug Fix Description: The datatype conversion buffer size was only halfway converted from hsize_t to size_t and was causing problems. Also, the H5P_peek_<foo> routines have a bunch of identical code. Solution: Finished converting the datatype conversion buffer size to size_t and cleaned up the implementation of the H5P_peek_<foo> routines to call a common routine instead of reimplementing a bunch of code. Platforms tested: Solaris 2.7 (arabica)
* [svn-r4324] Purpose:Quincey Koziol2001-08-101-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | New Features! Description: Start migrating the internal use of property lists in the library from the older implementation to the new generic property lists. Currently, only the dataset transfer property lists are migrated to the new architecture, all the rest of the property list types are still using the older architecture. Also, the backward compatibility features are not implemented yet, so applications which use dataset transfer properties may need to make the following changes: H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW) and H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id) This still may have some bugs in it, especially with Fortran, but I should be wrapping up those later today. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-4/+4
| | | | | | | | | | | | | | | | | | 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-r3559] Purpose:Quincey Koziol2001-03-081-1/+1
| | | | | | | | | | C++ compatibility fix Description: 'delete' is a reserved word in C++ Solution: Change structure member named 'delete' into 'del' Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3520] Purpose:Quincey Koziol2001-02-271-0/+1
| | | | | | | | | | | | | Code checkpoint Description: Checkpointing generic property code before removing the older [non-generic] property list implementation and switching all the property lists to use the generic code. Generic properties are feature complete and as fully tested as I can determine. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3268] Purpose:Quincey Koziol2001-01-111-1/+1
| | | | | | | | | | | Code cleanup for C++ Description: 'xor' is a keyword in C++, causing problems compiling the library with a C++ compiler. Solution: Change variables and structure fields from 'xor' to 'xor_val' Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3010] Purpose:Quincey Koziol2000-11-281-0/+1
| | | | | | | | | | | | | | Bug fix Description: When the v1.2 compatibility code was turned on, internal functions in the library were getting confused. Solution: Separated guts of H5Pget_driver call into an API function (the definition of which depends on the compatibility switch) and an internal function which always behaves like the v1.3/4 function. Replaced API function calls in the library code with the internal function. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r2909] Purpose:Quincey Koziol2000-11-151-2/+2
| | | | | | | | Code checkpoint Description: More generic property functionality added and debugged. Platforms tested: FreeBSD 4.1.1 (hawkwind)

* [svn-r2868] Purpose:Quincey Koziol2000-11-111-2/+2
| | | | | | | | | | Bug Fix Description: Generic property lists were leaking memory. Solution: Tied them into the regular cleanup code called at the library's termination Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)
* [svn-r2860] ./hdf5/src/H5Pprivate.hRobb Matzke2000-11-101-13/+19
| | | | | | | * 2000-11-10 Robb Matzke <matzke@llnl.gov> Changed `class' to `cls' in various places since the former is a C++ reserved word and some C compilers (like the one on blue) complain.
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-1/+1
| | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c Fixed more dependency problems in H5_term_library(). There was a bug in the previous version that could cause the wrong EOF marker to be written to the boot block under certain circumstances. Hopefully this fixes it although I don't ready access to a test case (Mark Miller will test it). ./src/H5F.c ./src/H5Fprivate.h Added an H5F_close_all() that is similar to H5F_term_interface() but which doesn't close the interface. Files that don't have open object headers are closed, others are delayed until all object headers close.
