* [svn-r27768] Description:Quincey Koziol2015-09-141-357/+330
| | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them.

Added code to H5E_register_class to free cls in case of an error. r18142: Fix coverity item 91. Added code to H5E_create_msg to free msg in case of an error. r18143: fixed issue 14, took away "if" and used #ifndef_xxx. r18144: Fix coverity item 110. Added code to H5Eget_minor to free msg_str in case of an error. r18145: fixed coverity #18 removed "aligned", it is always NULL. r18146: Fix coverity item 109. Added code to H5Eget_major to free msg_str in case of an error. r18147: Fixed coverity #81 and #82, Check for bad pointer(s), but can't issue error, just leave r18148: Fix coverity item 97.

| | | | | | | | | | | | | Bring r16846 from revise_chunks branch back to trunk: Fix broken (for how long?) H5_ASSIGN_OVERFLOW macro to actually detect overflows during assignments, along with several errors it [now] detected. Cleaned up a fix minor warnings and/or pieces of code also. Tested on: FreeBSD/32 6.3 (duty) in debug mode (h5committest not needed - multi-platform test performed on branch)
* [svn-r16702] Purpose: Improve performance of factory free lists.Neil Fortner2009-04-081-156/+435
| | | | | | | | | | | Description: Factory free lists were formerly implemented as block free lists. This was inefficient as factories can only be one size, and implementing them as blocks (which can be variable size) wastedd computation and space. They have been rewritten with a separate implementation, which is simlar to regular free lists except they can be dynamically created and destroyed. Tested: jam, linew, smirom (h5committest)

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-5/+30
| | | | | | | | | | | | | | | 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.

Refactor common code to only one location. Allow I/O operations to succeed on null dataspaces. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r8301] Purpose:Quincey Koziol2004-04-061-192/+269
| | | | | | | | | | | | | Code optimization Description: Move handling for free list arrays that have no maximum size to separate set of routines and optimize computations for free list arrays with maximum size to avoid re-computing sizes all the time. Platforms tested: h5committest Solaris 2.7 (arabica)
* [svn-r7924] Purpose:Quincey Koziol2003-12-101-0/+6
| | | | | | | | | | | Code cleanup Description: Add more assertions to detect attempted allocations of zero-sized blocks. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel too minor to require h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-16/+16
| | | | | | | | | | | | | | | | | | | 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)

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?

| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Hyperslab code for collapsing dimensions was incorrectly collapsing selections inappropriately when the fastest changing dimension couldn't be collapsed. Also add some more assertions which will make similar bugs easier to find. Solution: Break out of loop earlier. Platforms tested: modi4 (parallel), too small to triple check.

| | | | | | | | | | | | | 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 Koziol2002-08-081-23/+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-r5785] Purpose:Quincey Koziol2002-07-121-51/+0

* [svn-r5471] Purpose:Quincey Koziol2002-05-291-10/+10
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-23/+31
| | | | | | | | | | | | | | | | | | | | | | | | 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-r4842] Purpose:Quincey Koziol2002-01-171-52/+44
| | | | | | | | | | | | Feature improvement Description: Re-write how the free-list headers were used, to reduce the amount of space added to each malloc request. Reduced header for array and block free list items from 24 bytes to 8 bytes and eliminated the header for fixed-size free list items entirely. This should reduce the amount of memory that the library uses. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)

| | | | | | | | | | | | | | Code speedups, etc. Description: Bring in new algorithms and data structures for dealing with hyperslabs. This speeds up the hyperslab I/O for non-regular hyperslabs by a huge amount. Currently, the new API functions are ifdef'ed out, pending discussion and consensus approval. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-14/+14
| | | | | | | | | | | | | | | | | | | | | | 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)
