* [svn-r7917] Purpose:Quincey Koziol2003-12-061-9/+9
| | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes and code cleanup Description: Lots of changes here: - Fixed bug #691 - when shared datatypes are used in attributes they are incorrectly copied into the attribute instead of referring the the named datatype in the file. This required bumping the version of the attribute message. The new version of the attribute message is only written out when a shared datatype is used in the attribute. [Also, this format change made the size of the attribute smaller.] - Added information to attribute debugging routine so that shared datatypes are displayed correctly with the h5debug tool. - Refactored the H5O* routines to extract code that was common to several routines into subroutines to call. - Added 'link' method for H5O message sub-classes, which increments the link count on shared objects when a message is created which shares them. - Corrected [unreported] bug where the link count was not being decremented on the shared object when a object header message with a reference to that object was deleted from the file. - Reduced size of shared message from 49 bytes (which was incorrect anyway and should have been 48 bytes) to 10 bytes, which required bumping the version of "shared" messages. - Refactored some of the shared datatype routines to allow for easier queries of "committedness" internally to the library and also added routine to easily increment/decrement the reference count of a shared datatype.

* [svn-r6411] Purpose:Quincey Koziol2003-02-171-42/+44
| | | | | | | | | | | | | | | | | | | | | | 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-r6387] Purpose:Quincey Koziol2003-02-101-41/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | 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 Koziol2002-08-081-206/+183
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-29/+11
| | | | | | | | | | | | | | 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-r5471] Purpose:Quincey Koziol2002-05-291-15/+15
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | 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-r4772] Purpose:Quincey Koziol2002-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Bug Fix. Description: Equation to compute size of attribute in memory was incorrectly using the disk's datatype (and dataspace, but that turns out not to have been the actual issue) and when a variable length datatype was used for the attribute, the wrong size is being computed. Also, the variable-length datatype conversions aren't handling the default dataset transfer property list (H5P_DEFAULT) correctly. Solution: Changed attribute code to compute the attribute size in memory correctly by using the memory datatype & dataspace. Changed the variable-length datatype conversion code to use the default dataset transfer property list when H5P_DEFAULT is passed as the property list ID. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-49/+25
| | | | | | | | | | | | | | | | | | | | | | 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)
* [svn-r4584] Raymond Lu2001-11-021-7/+1
| | | | | | | | | Purpose: Switch from old property list to new generic property list. Description: Mainly changed H5Pcreat, H5Pclose, H5Pcopy. Platforms tested: IRIX64 6.5, FreeBSD, SunOS 5.7.
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-8/+8
| | | | | | | | | | | | | | | | | | | | | | 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)

Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [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-r3252] Purpose:Quincey Koziol2001-01-091-27/+31

| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O.

This was fixed by splitting the `stride' argument into `buf_stride' and `bkg_stride' arguments for all the conversion functions. THIS IS AN API CHANGE, but users will get a compiler warning when they pass their conversion function pointer to H5Tregister(). ** src/H5T.c ** src/H5Tprivate.h Added a bkg_stride argument to the H5T_convert() definition in order to fix a bug related to the optimized compound datatype conversion function. ** src/H5T.c ** src/H5A.c ** src/H5D.c ** src/H5Ofill.c ** src/H5P.c Added bkg_stride=0 argument to the H5T_convert() calls. ** test/dtypes.c Added a test for the H5T_conv_struct_opt() bug fixed above. ** src/H5FL.c The H5FL_term() function should return non-zero even when it couldn't free all the free lists do to their being used by some other package. When that other package terminates it will return non-zero, causing H5FL_term() to be called again. This fixes some of the `infinite loop closing library' messages. ** tools/pdb2hdf Uses print_version() instead of doing that itself. ** src/H5Ppublic.h Renamed H5Pget_gc_reference() declaration to make it match the definition. ** src/H5FDlog.c Added API tracing macros. Removed `const' qualifier from a `char*' member of a struct which was allocated on the heap. ** src/H5TB.c Added curly braces to a couple deeply-nested `if' statements to make them clearer and to shut up the increadibly stupid and just plain incorrect gcc warning about ambiguous `else'. ** test/titerate.c Removed incomplete initialization in favor of memset() for one auto variable to stop compiler warnings. ** tools/Depencencies Regenerated to remove references to h5dumputil.c

If the value is zero then the old behavior is preserved (source and destination values are packed). This feature was necessary to implement the compound datatype conversion optimizations and it causes a minor change to the API (application-defined type conversion functions take an extra size_t stride argument). ./src/H5Tconv.c An additional compound data type conversion function was added which is applied unless the destination type is larger than the source type. I'm measuring significant performance increases for certain operations: Test Name Struct-Conv Noop-Conv New(Old) MB/s New(Old) MB/s ---------- ------------- ------------- Reordering 2.062(0.3936) 54087(0.9047) Subsetting 2.901(0.6581) 40192(1.1100) Shrinking 1.976(0.3925) 33628(1.1500) ---------- ------------- ------------- ./test/dtypes.c Added various compound datatype conversion tests. Fixed return values from functions. ./src/H5T.c Conversion timers are updated only if H5T debugging is turned on a runtime (in addition to compile time).

The stride is always zero, which means that the source and destination data values are packed. ./configure.in ./configure [REGENERATED] If API tracing is turned off then libhdf5.settings will say `no' instead of nothing. ./test/flush1.c ./test/flush2.c Added better error messages in a couple places.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./doc/html/Datatypes.html ./test/dtypes.c Added documentation and tests for opaque types. ./tools/h5ls.c Added a `-x' or `--hexdump' argument which is not fully implemented (because I want to synchronize h5tools.c first) but which will eventually print raw data in hexadecimal format without any translation from disk. This would be useful for debugging references and VL types. ./tools/h5tools.c Added support for references (not quite finished yet, but compiles -- I wanted to sync up this file before Patrick and I got too far apart...) ./src/H5R.c Checked for error return value from H5R_get_object_type() ./src/H5A.c ./src/H5D.c Changed error return values from NULL to FAIL ./test/Makefile.in ./test/trefer.c Creates trefer1.h5 and trefer2.h5 so that the second test doesn't clobber the first file since the files might be useful for debugging.

The fix works only on systems that have the vsnprintf() function (otherwise a 4kB limit is imposed, which if violated probably dumps core). If vsnprintf() is present then the library dynamically allocates space for the output string. Also made it possible to control how compound data is rendered across multiple lines of output by allowing the caller to specify where optional line-breaks get inserted. The output functions split up the value at one or more optional line-breaks to prevent it from wrapping around the screen. If a datum doesn't fit on the current line but would fit on the next line then it is printed on the next line regardless of whether optional line-breaks would have prevent wrapping around the screen. This makes it easier to find the beginnings of compound data values. This feature is disabled by default but can be enabled by the application. If a datum doesn't fit on the current line and the previous datum also occupied more than one line then we move to the next line before printing. This makes it easier to find the beginnings of compound data values but prevents the output from looking fragmented if there are only a few long values among mostly short values. This feature is disabled by default but can be enabled by the application. The application can control the printf() formats used for all the native data types. The defaults are what the library used to use: %g, %ld, %lu, %d, and %u ./tools/h5ls.c Compound datatype values can now be split across multiple lines of output instead of just wrapping. Also, when lots of compound values are too long they all start at the beginning of a line. This only required about 10 lines of changes in the setup for tools library calls (I didn't modify the h5dump program because it uses its own version of the tools library that forked off long ago). Added code for Win32 which is unable to cast `unsigned long long' to `double'. If the dataset size exceeds (2^63)-1 then the percent utilization is not displayed (this is easily possible with chunked datasets). This is untested yet. ./configure.in ./src/H5config.h.in ./src/H5.c ./src/H5private.h Check for vsnprintf() and provide a simple, stupid definition if it isn't available. The stupid definition just calls vsprintf() and ignores the second argument. This can result in buffer overflows in h5ls and h5dump since vsprintf() is an unsafe function (and anyone can create an hdf5 file that runs an arbitrary command from h5ls and h5dump in that case)! ./config/conclude.in Remove more *.o files for `make clean' ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c Cleaned up a memory leak during H5_term_library() by allowing H5I_clear_group() to skip items that couldn't be freed. This allows the item to remain in the group until we can free it later. ./src/H5F.c The H5F_close_all() function fails if a file cannot be closed.

| | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5A.c ./src/H5D.c The `bkg' buffers are zeroed before calling the type conversion function. This fixes a problem where reading a file compound data structure into memory results in garbage between the members. ./src/H5I.c Fixed H5I_clear_group() so it removes entries even when a free callback is not registered. This fixes fixes an `infinite loop closing library' warning message. ./src/H5.c Added ellipses to the end of the infinite loop message.

Also fixed a bug for undefined variable in H5D when H5S debugging is turned on but H5T debugging is turned off. ./config/conclude.in Fixed installation of header files for building in a directory other than the source directory. This fixes a bug where H5config.h wasn't being installed. ./src/H5.c ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c ./src/H5Tprivate.h ./src/H5Z.c ./src/H5detect.c ./src/H5private.h Changed the way the library shuts down again. Now it handles cycles between packages and isn't so sensitive to dependencies between packages. A package might shut down only to be restarted to process a request from some other package being shut down. Loops are detected after 100 iteractions and the shutdown is aborted with a message on standard error. This also makes it a lot easier to debug. ./src/H5A.c Fixed H5A_write() and H5A_read() so they pass a non-null background buffer to the conversion functions. This is necessary when an attribute has a compound data type. ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c Reindented new Win32 stuff. ./src/H5Odtype.c Fixed a bug when enumeration types are used in a compound data type. The byte pointer wasn't incremented after the type information was written. ./tools/h5ls.c Compound data types display their total size because it's not always obvious from looking at the members. Scalar attributes show their space as `scalar' instead of `{}'. The index value is not printed for attributes that have only a few values. Instead the word `Data:' is printed on the first line of attribute data. Named types display their data type only if verbose output was requested.
