* [svn-r7988] Purpose:Quincey Koziol2003-12-291-1/+1
| | | | | | | | | | | Bug fixes & code cleanup Description: Back out some of the debugging that was inadvertently checked in recently. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7984] Purpose: bug fixRaymond Lu2003-12-291-2/+3
| | | | | | | Description: VL datatype fails in certain way(hard to describe) Platforms tested: 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)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omnibus floating-point bug fix changes Description: There are a number of problems in the floating-point conversion code that were exposed by Ray's recent int<->float checkin: - The 'my_isnan' code in test/dtypes.c was broken and would always return true. The meant that the actual values in the float<->float conversion tests were _never_ checked, hiding the other bugs included in this checkin. - A recent change I made to the type conversion code used "FLT_MIN" instead of "-FLT_MAX" for the most negative 'float' value for the double->float conversion, which meant that any the negative number that was converted from a double to a float would have been mapped to zero, essentially. - A change that Robb appeared to have made ~2.5 years ago to the "generic" float->float conversion routine appears to be incorrect and I've backed it out. - Floating-point conversions on SGI's which converted denormalized values would be mapped to zero instead of being propertly preserved in the new type. This was addressed by an SGI-specific system call to prevent the behavior. Solution: Described above, generally. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Misc. update: release_docs/RELEASE update forthcoming...

* [svn-r7868] Purpose: new featureRaymond Lu2003-11-211-0/+1303
| | | | | | | | | | Description: data type conversion between integers and float numbers. (Cover your ears. It's going to explode.:) Solution: covers all native type conversion. Mainly uses hardware conversion but handles overflow more gracefully. Platforms tested: h5committest
* [svn-r7842] Purpose:Quincey Koziol2003-11-131-72/+80
| | | | | | | | | | | | | | | | | | | 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-r7824] Purpose:Quincey Koziol2003-11-071-53/+96
| | | | | | | | | | | | | | | Code optimization Description: Improved integer & floating-point datatype conversions by removing some corner cases. Got rid of algorithm which walked the buffer of elements to convert backwards, switching to algorithm which computes the non-overlapping space in the buffer and repeatedly converts it in the forward direction. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Cray SV1 & T3E (T90 is not accessible)
* [svn-r7667] Purpose:Quincey Koziol2003-10-181-7/+6
| | | | | | | | | | | Optimize code Description: Eliminate some computations from inner loop, giving about a 5% speedup. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to h5committest
* [svn-r7666] Purpose:Quincey Koziol2003-10-181-125/+81

* [svn-r7665] Purpose:Quincey Koziol2003-10-181-203/+58
| | | | | | | | | | | | Refactored code Description: Switched float->double and double->int conversions to use new, more generic conversion looping macros. Platforms tested: FreeBSD 4.9 (sleipnir) too small to require h5committest
* [svn-r7664] Purpose:Quincey Koziol2003-10-181-75/+124
| | | | | | | | | | | | | | More refactoring Description: Re-wrote inner loop of integer conversion routines with "psuedo-template" macros, to hoist 'if-else's out of inner loop in an easy to understand way. This speeds up the integer type conversions by 15-20%. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7662] Purpose:Quincey Koziol2003-10-181-194/+222
| | | | | | | | | | | | | | | | | Refactor integer conversion macros Description: Turned integer conversion macros "inside" out, using an interlocking macro technique similar to templates in C++. The macro which actually performs the conversion is now invoked "genericly" from inside another macro, which will allow the inner conversion loop to be optimized in a much easier way. This "psuedo-template" technique could be useful for other semi-repetitious patterns in the library - possibly the datatype initialization code...

* [svn-r7591] Purpose:Quincey Koziol2003-10-101-3/+1
| | | | | | | | | | | | Bug fix Description: Correct the size of the buffer needed for the destination value to use the actual destination type size. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7580] Purpose:Quincey Koziol2003-10-091-10/+13
| | | | | | | | | | | | | | | | | Bug fix Description: The VL type conversion routine attempt to align it's destination buffer to an offer that will work for both hvl_t and char * types, but the algorithm used fails to work correctly on Cray machines. Solution: Give up on attempting to align the buffer when it's allocated on the stack. Just dynamically allocate it instead. Platforms tested: FreeBSD 4.9 (sleipnir) Cray SV1 (wind)
* [svn-r7334] Purpose:Quincey Koziol2003-08-111-5/+33

| | | | | | | | | | | | | | | Bug fix Description: Fix "unaligned access" warning on IA64 (and alpha, probably) machines. Solution: Make certain that temporary destination buffer is aligned on correct boundary for type conversion. Platforms tested: IA64 Linux cluster (titan) too small for h5committest

| | | | | | | | | | | | | | | | | | Bug fix Description: Aligned data is not being detected by type conversion routines correctly on some Crays, causing corrupted data during I/O. Solution: Add extra checking for strange pointer behavior on Crays. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest Cray SV1 (wind) Cray T3E (hubble) Cray T90 (gypsy)

* [svn-r6837] Purpose:Quincey Koziol2003-05-081-2/+2
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested
* [svn-r6395] Purpose:Quincey Koziol2003-02-121-13/+24
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Break up the ~9350 line H5T.c module into smaller pieces, which contain code for a particular feature or support for a datatype class. This should make the "main" H5T code (still in H5T.c) easier to support, as well as removing some of the "minor" routines from the user applications which don't use them (my rough estimates show about 4% reduction (~30K on a FreeBSD machine) in optimized, staticly-linked binaries for very simple programs) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) Misc. update: Update MANIFEST

| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

* [svn-r6252] Purpose:Quincey Koziol2003-01-091-64/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | Purpose: Improve error handling Description: make error handling better for VL string null pointer. Platform tested: arabica
* [svn-r5842] Purpose:Quincey Koziol2002-08-081-1768/+1818
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-127/+54
| | | | | | | | | | | | | | 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-r5834] Purpose:Quincey Koziol2002-07-241-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large code cleanup/re-write Description: This is phase 1 of the data I/O re-architecture, with the following changes: - Changed the selection drivers to not actually do any I/O, they only generate the sequences of offset/length pairs needed for the I/O (or memory access, in the case of iterating or filling a selection in a memory buffer) - Wrote more abstract I/O routines which get the sequence of offset/ length pairs for each selection and access perform the I/O or memory access. Benefits of this change include: - Removed ~3400 lines of quite redundant code, with corresponding reduction in the size of library binary. - Any selection can now directly access memory when performing I/O, if no type conversions are required, instead of just "regular" hyperslab and 'all' selections, which speeds up I/O. - Sped up I/O for hyperslab selections which have contiguous lower dimensions by "flattening" them out into lesser dimensional objects for the I/O. No file format or API changes were necessary for this change. The next phase will be to create a "selection driver" for each type of selection, allowing each type of selection to directly call certain methods that only apply to that type of selection, instead of passing through dozens of functions which have switch statements to call the appropriate method for each selection type. This will also reduce the amount of code in the library and speed things up a bit more. Phase 3 will involve generating an MPI datatype for all types of selections, instead of only "regular" hyperslab and 'all' selections. This will allow collective parallel I/O for all I/O operations which don't require type conversions. It will also open up the door for allowing collective I/O on datasets which require type conversion. Phase 4 will involve changing the access pattern to deal with chunked datasets in a more optimal way (in serial). Phase 5 will deal with accessing chunked datasets more optimally for collective parallel I/O operations. Platforms tested: FreeBSD 4.6 (sleipnir) w/ parallel & C++ and IRIX64 6.5 (modi4) w/parallel

* [svn-r5471] Purpose:Quincey Koziol2002-05-291-105/+286
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | 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-r5191] Purpose:Quincey Koziol2002-04-171-32/+63
| | | | | | | | | | | | | | | | | | | Bug fix Description: When several level deep nested compound & VL datatypes are used, the data in the nested compound datatypes is incorrectly sharing the same "background buffer", causing data corruption when the data is written to the file. Solution: Allocate a separate background buffer for each level of the nested types to convert. (Also allocate temporary background buffers for array datatypes, where this sort of problem could occur also) Added more regression tests to check for these errors. Platforms tested: FreeBSD 4.5 (sleipnir) & Solaris 2.6 (baldric)

| | | | | | | | | | | | | | More optimizing for byte order conversion. Mostly just making code easier to follow by simplifying Duff's device coding of the loops. I also split the conversion function into two functions with different names so output from H5T debugging indicates whether the optimized or unoptimized case was invoked. 2002-01-25 10:48:54 Robb Matzke <matzke@arborea.spizella.com> * H5T_conv_order: Removed Duff's device consisting of >500 lines of code.

* [svn-r4643] Purpose:Quincey Koziol2001-11-271-521/+519
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)
