* [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.

| | | | | | | | | | | Code cleanup Description: Fix some warnings & formatting issues Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4
* [svn-r11886] Purpose:Quincey Koziol2006-01-231-3/+3
| | | | | | | | | | | | | Code cleanup Description: Check in some of the code cleanups from working on the external link support. (This doesn't include any of the external link features) Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX.4 (amazon) Linux 2.4
* [svn-r11838] Purpose:Quincey Koziol2005-12-261-2/+2
| | | | | | | | | | | | | | | | Bug fix Description: Retrieving an object's name could fail (in various ways) under certain circumstances (mostly having to do with mounted files). Solution: Re-write & simplify "get object name" code to fix error in a better way than adding yet another hack to the previous pile of hacks... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11712] Purpose:Quincey Koziol2005-11-151-8/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)
* [svn-r11282] Purpose:Quincey Koziol2005-08-201-1/+1
| | | | | | | | | | | | | | | | | New debugging feature Description: Add some code to track where memory from the internal free list allocator is allocated within the library. It's not quite ready for "prime time" yet, but it's close enough to be useful. This is disabled by default and requires the H5FL_TRACK macro in src/H5FLprivate.h to be uncommented to activate during debugging. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Too minor to require full h5committest

| | | | | | | | | | | | | | Description: Removed PABLO from the source Solution: Platforms tested: arabica with 64-bit, copper with parallel, heping with GNU C and C++ and PGI fortran (but I disabled hl, there is some weird problem only on heping: F9XMODFLAG is not propagated to the Makefile files Misc. update:
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-40/+15
| | | | | | | | | | | | | | | 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-r7917] Purpose:Quincey Koziol2003-12-061-2/+2
| | | | | | | | | | | | | | | | | | | 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-r6843] Purpose:Quincey Koziol2003-05-091-1/+1
| | | | | | | | | | | | 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-r6823] Purpose:Bill Wendling2003-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code Improvements/Bug Fixes Description: Comparison of equality of a double/float variable to 0.0 is not guaranteed to work and is bad practice. In H5Fcontig.c, a warning was given by a statement like: x = (++x) % y; This could be confusing to a compiler I suppose. In H5RS.c, a typedef of a structure was being tagged by the compiler as "useless" because it had the form: typedef struct foo { int var1; /* ... */ }; /* <--- note no name for this typedef */ The statement "typedef struct foo foo" is already in the header file. Solution: Test that the absolute value of the variable is < a very small positive number. Changed "x = (++x) % y" to "++x; x %= y;" instead. Removed the "typedef" from the structure in the H5RS.c file. Platforms tested: Modi4 (Parallel & Fortran) Verbena (C++ & Fortran) Arabica (Fortran) Misc. update:

* [svn-r6433] Purpose:Quincey Koziol2003-02-241-11/+97
| | | | | | | | | | | | | | | Code/comment cleanup Description: Made more information about reference-counted strings private to the H5RS package by trimming the typedef used in H5RSprivate.h and switching from using macros for a couple of operations to using functions. Updated copyright information for a few of these files. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}
* [svn-r6301] Purpose:Quincey Koziol2003-01-181-1/+1
| | | | | | | | | | | Code cleanup & bug fix Description: Cleanup another set of warnings on Windows and also fix mis-placed assertion that caused the daily tests to fail. Platforms tested: IRIX64 6.5 (modi4) w/-n32
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-9/+9
| | | | | | | | | | | | 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-r6252] Purpose:Quincey Koziol2003-01-091-0/+390
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.
