* [svn-r14115] Description:Quincey Koziol2007-08-281-4/+4
| | | | | | | | | | | | | | | | | Remove all plain calls to H5Gopen() from source, replacing them with either H5Gopen2(). Add test for H5Gopen1(). Reformatted several pieces of code, to clean them up. Tested on: FreeBSD/32 6.2 (duty) FreeBSD/64 6.2 (liberty) Linux/32 2.6 (kagiso) Linux/64 2.6 (smirom) Solaris/32 5.10 (linew) Mac OS X/32 10.4.10 (amazon)

| | | | | | | WIN32, so I've standardized all #ifdef's to use _WIN32. This should not affect any other platform. Tested: Visual Studio (32- and 64-bit) on Win XP
* [svn-r13544] Some minor adjustment from last round of checkin. Tested on kagisoRaymond Lu2007-03-261-1/+1

* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r12833] Description:Quincey Koziol2006-10-311-4/+4
| | | | | | | | Clean up more warnings... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-39/+39
| | | | | | | | | | | | | | | | | | | | 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-r8053] Purpose:Quincey Koziol2004-01-131-1/+130
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct two problems with variable-length datatypes in datasets: - When overwriting an entire dataset, writing the fill value to the file would be skipped, causing problems for VL datatypes when objects in the file had been unlinked (and thus the space in the file was not all zeros) - When an application has set a fill-value for a dataset and the dataset's datatype contained a VL datatype, the library was filling space on disk with the memory form of the VL information, instead of the disk form. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r8048] Purpose:Quincey Koziol2004-01-101-55/+30
| | | | | | | | | | | | | Code cleanup & reorganization Description: Move further in the testing framework cleanup, eliminating all the global variables (moving them into testframe.c as static variables) from the testing framework code and moving it into the libh5test.a. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o thread-safety, c++ & parallel h5committested
* [svn-r7842] Purpose:Quincey Koziol2003-11-131-7/+56
| | | | | | | | | | | | | | | | | | | Bug fix Description: Variable length strings and sequences with NULL pointers were not handled by library, causing problems access the data. This also affected fill values for variable-length datatypes. Solution: Address the issues in the library by detecting NULL sequences/strings and avoid trying to convert them. Patched up dumper to display NULL sequences/strings. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r6843] Purpose:Quincey Koziol2003-05-091-1/+0
| | | | | | | | | | | | Code cleanup Description: Clean up warnings exposed by compiling on O2K. Also, revert some of Bill and my changes to the H5S_mpi_opt_types_g, etc. and settle them back into their original location. Platforms tested: h5committested.

* [svn-r6252] Purpose:Quincey Koziol2003-01-091-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6171] Purpose:Quincey Koziol2002-12-041-19/+57
| | | | | | | | | | | | | Bug fix Description: Much of the VL-string testing code was recently disabled accidentally. Solution: Re-enable it and add test for writing/reading large string attributes. Platforms tested: FreeBSD 4.7 (sleipnir) - small enough to not need triple-check
* [svn-r6145] Raymond Lu2002-12-021-8/+32
| | | | | | | | | | 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

| | | | | | | | | | Code Cleanup Description: Clean up compiler warnings from the last bunch of checkins Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5123] Raymond Lu2002-03-291-1/+74
| | | | | | | | | | | Purpose: Bug fix(#697) Description: Variable-length string wasn't treated as string. Solution: Added character set and padding into VL string type. Platforms tested: FreeBSD
* [svn-r4773] Purpose:Quincey Koziol2002-01-041-0/+124
| | | | | | | | | | Regression test Description: Added regression test which stores variable length strings as an attribute. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4482] Purpose:Quincey Koziol2001-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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-r4355] Purpose:Quincey Koziol2001-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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-r4324] Purpose:Quincey Koziol2001-08-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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-r3770] Purpose:Bill Wendling2001-04-031-2/+2
| | | | | | | | | | | | | | | | | Update Description: Changed includes of the form: #include <hdf5_file.h> to #include "hdf5_file.h" so that gcc can pick them up easier without including the system header files since we don't care about them. Platforms tested: Linux
* [svn-r3745] Purpose:Quincey Koziol2001-04-011-3/+3
| | | | | | | | | | | Code Tweaks Description: "FILE" macro for file names was getting confused with Standard C __FILE__ macro on certain platforms. Solution: Changed "FILE" macro usage to "DATAFILE" Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3677] Purpose:Albert Cheng2001-03-201-4/+0
| | | | | | | | | | | | | Bug fix (sort of) Description: The RCSID string in H5public.h was causing the C++ code problem as it was included multiple times and C++ did not like multiple definitions of the same static variable. Solution: Since we don't really make use of the RCSID strings as we have not installed it in all source files, we decided to remove it. Platforms tested: eirene (linux), modi4 (IRIX64-64) both serial and parallel modes.
* [svn-r3234] MuQun Yang2001-01-031-0/+4
| | | | | | | | | | | | Purpose: a bug fix Description: without explicitly including stdio.h in this file, it will fail in compiling at the first time of building up the library. It needs to be recompiled separetely. Now it can work. The real reason is to be investigated. Solution: adding include <stdio.h> for win32. Platforms tested: win 2000
* [svn-r3005] Purpose:Quincey Koziol2000-11-271-1/+1
| | | | | | | | Backward compatibility code Description: Add in code to allow the library to emulate the v1.2 API and behavior. Platforms tested: FreeBSD 4.2 (hawkwind)
