* [svn-r7875] Purpose:Quincey Koziol2003-11-241-0/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...

| | | | | | | | | | 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-r7682] Purpose:Quincey Koziol2003-10-211-210/+164
| | | | | | | | | | | | | | | Bug fix Description: Remove the [duplicated] native C9x datatype initializatin code from H5T.c and let the automatically generated code in H5Tinit.c handle initializing them, if they are allowed by the compiler. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena, eirene) probably should be h5committested, but it's late and I'm fairly certain this will fix the problem... :-/

| | | | | | | | | | | | | | | Bug fix Description: Avoid "OPAQUE" symbol in template macro invocation, since it's already defined as a macro on Windows. Solution: OPAQUE -> OPAQ Platforms tested: FreeBSD 4.9 (sleipnir) Windows ? (Pedro's machine :-)
* [svn-r7674] Purpose:Quincey Koziol2003-10-201-5/+5

* [svn-r7669] Purpose:Quincey Koziol2003-10-201-1233/+377
| | | | | | | | | | | | | | | Refactor code Description: Use "template macro" technique to eliminate a huge amount of repeated code in type initialization code (almost 1000 lines, between this change and the changes to the H5Tconv.c file earlier). This centralizes the common parts of the code and makes the different parts of the code more obvious. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7616] Purpose:Quincey Koziol2003-10-131-44/+42
| | | | | | | | | | | | | | | Code cleanup Description: Change field member count and indices for compound and enumerated types from 'int' to 'unsigned' to better reflect actual use. Cleaned up a few other minor compiler warnings, etc. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena) too minor to require h5committest
* [svn-r7468] Purpose:Quincey Koziol2003-09-121-3/+7
| | | | | | | | | | | | | | | | | | Code cleanup, etc. Description: Generalize Ray's datatype fixes to handle packing compound datatypes which are the base type of an array or variable-length type, etc. Also track "packedness" of a compound datatype from it's creation, instead of only setting the 'packed' flag after the datatype was explicitly packed. Updated docs to reflect that a compound datatype is allowed to grow (but not shrink). Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7461] Purpose: bug #1017Raymond Lu2003-09-101-4/+6
| | | | | | | | Description: H5Tpack fails if called twice or datatype is locked. Compound datatype wasn't expandable. Platforms tested: h5committest
* [svn-r7438] Purpose:Quincey Koziol2003-09-021-82/+14

* [svn-r7434] Purpose:Quincey Koziol2003-08-311-27/+38
| | | | | | | | | | | | | | | | | | | | Bug Fix and code cleanup Description: Correct error in H5T_detect_class that was causing nested compound datatypes with to not detect the datatype class of fields correctly, which caused errors with fill-values, variable-length datatypes and chunks later on. Return the rank of the array datatype from H5Tget_array_dims(), like H5Sget_dims(). Lots of cleanups to datatype code, to make the handling of arrays, compound types, variable-length strings and sequences and enumerated types more consistent and robust.

* [svn-r6837] Purpose:Quincey Koziol2003-05-081-4/+57
| | | | | | | | | | | | | | | 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.

* [svn-r6411] Purpose:Quincey Koziol2003-02-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.
* [svn-r6395] Purpose:Quincey Koziol2003-02-121-4078/+30
| | | | | | | | | | | | | | | | | | | | | | | 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
* [svn-r6388] Purpose:Quincey Koziol2003-02-101-3/+3
| | | | | | | | | | | | | Update feature Description: Relax collective constraint for API functions which only read metadata from a file. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 w/parallel
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-145/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-118/+118
| | | | | | | | | | | | Code cleanup/new feature. Description: Split FUNC_LEAVE into API and non-API specific versions.

* [svn-r6252] Purpose:Quincey Koziol2003-01-091-61/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6064] Purpose:Bill Wendling2002-11-071-4/+4
| | | | | | | | | | Code Cleanup Description: A function was returning "NULL" instead of "FAIL" for an error condition. Renamed the variable "class" to "h5_class" since class is a keyword in C++ and might mess up with a C++ compiler... Platforms tested: Eirene pp (too small a change for 3 tests)

| | | | | | | | | | | | | | | | | Purpose: Merged from 1.4 branch Description: API tracing improvements Platforms tested: Linux (--disable-hsizet didn't work before my changes and still doesn't work, but --enable-hsizet is fine). Note: This checkin includes temporary code in H5FDmpiposix.c to turn off GPFS byte range token prefetches on ASCI/Blue. Once the HDF5 API supports the necessary prerequisite functionality this temporary code can be migraged up above HDF5.
* [svn-r5843] Purpose:Quincey Koziol2002-08-081-2/+2

* [svn-r5842] Purpose:Quincey Koziol2002-08-081-1354/+1112
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-176/+77
| | | | | | | | | | | | | | 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-r5595] Elena Pourmal2002-06-111-7/+17
| | | | | | | | | | | | | | | Purpose: Bug #774 fix Description: H5Tenum_valueof and H5Tenum_nameof functions did not fail when non-existing name or non-existing value were supplied. This happened because binary search algorithm did not check if value or name found during the search were equal to the supplied one. Solution: Added an appropriate check condition. Platforms tested: Solaris 2.7 and Linux 2.2.18
* [svn-r5586] Purpose:Quincey Koziol2002-06-111-3/+61
| | | | | | | | | | | | | | | | Bug Fix Description: H5Dcreate and H5Tcommit allow "empty" compound and enumerated types (i.e. ones with no members) to be stored in the file, but this causes an assertion failure and is somewhat vapid. Solution: Check the datatype "makes sense" before using it for H5Dcreate and H5Tcommit. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5567] Purpose:Quincey Koziol2002-06-101-0/+2
| | | | | | | | | | | | | | Bug fix (bug #777) Description: Current code allows a compound datatype to be inserted into itself. Solution: Check if the ID for the member is the same as the ID for the compound datatype and reject it if so. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-92/+103
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | 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)
