| | | | | | | | | | | | | | | | | Feature Description: Added "support" for UTF-8 character encoding. Solution: Wrote tests to check that UTF-8 can be used in a number of places in HDF5 (object names, data, etc.). These tests live in test/tunicode.c. Added a new UTF-8 character encoding for datatypes. Platforms tested: mir, modi4, heping Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r9234] Purpose:Quincey Koziol2004-09-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Tweak recent "forward compatibility" changes to the H5E* API (which allowed for the old H5E API functions to remain unchanged) by allowing for the error stack callback function (H5E_auto_t) to also remain unchanged from the 1.6 branch. This required changing the H5E{get|set}_auto routines to have the old style H5E_auto_t type (which didn't have a stack ID parameter) and the new H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which has a stack ID parameter). This should make the H5E API changes as forwardly compatible as possible. One side-affect of this change was that it was impossible to determine if the current auto error callback was the old style (H5E_auto_t) or the new style (H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was adde to query this.

* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-5/+1
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack. Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt
* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance. Description: Replaced the old metadata cache with a cache with a modified LRU replacement policy. This should improve the hit rate. Solution: Since we want to flush cache entries in increasing address order, I used the threaded binary B-tree code to store the cache entries. There is a fair bit of overhead here, so we may want to consider other options. While the code is designed to allow the support of other replacement algorithms, at present, only a modified version of LRU is supported. The modified LRU algorithm requires that a user selectable portion of the cache entries be clean. The clean entries are evicted first when writes are not permitted. If the pool of clean entries is used up, the cache grows beyond its user specified maximum size. The cache can also exceed its maximum size if the combined size of the protected (or locked) entries exceeds the maximum size of the cache.

| | | | | | | | | | | | | | | | | | | | | feature Description: H5check_version will print warning messages if the version does not match or if the lib version string is not consistent, even when $HDF5_DISABLE_VERSION_CHECK is set to 1. This will mess up tests that try to match output. Changed it so that if $HDF5_DISABLE_VERSION_CHECK is set to 2, no warning about version mismatch is printed. The lib version string warning is suppressed if $HDF5_DISABLE_VERSION_CHECK is set to any non-zero value.

* [svn-r7051] Purpose:Quincey Koziol2003-06-181-9/+24
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When objects were left open in a file, the API shutdown code would end up closing property lists "out from underneath" files that were left open pending the objects in the being closed. This caused problems later when file objects would try to access their property list and fail to close, causing an infinite loop in the library shutdown. Solution: Create some dependencies in the order that APIs are shut down, trying to close "higher" level APIs before closing "low" level APIs. This still isn't precise, but it does work correctly now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r6387] Purpose:Quincey Koziol2003-02-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: New Feature; Optimization; Clean-up (Merged from 1.4 branch) Description: There is no symbolic constant to pass to functions that take an optional object ID for when the caller wants to indicate no object ID. In the past the caller always passed a negative integer. GPFS performs poorly. The h5ls tool decides whether to list the file name in the output based on a compile-time choice, which isn't always optimal at run time. Solution: Added a symbolic constant H5I_INVALID_HID. Added code to tell the mmfsd of GPFS to forego byte range token prefetching. h5ls decides whether to print the file name at runtime based on the number of objects being listed.

* [svn-r5814] Purpose:Quincey Koziol2002-07-191-0/+1
| | | | | | | | | | | | | | | | | | Bug Fix Description: It was possible to create corrupted metadata information (either in memory or in the file or both) with a parallel I/O program because of the way metadata writes were being handled for writes out of the metadata cache. Solution: Added a dataset transfer property called "block before metadata write" which is used by the MPI-I/O and MPI-posix drivers to sync up all the processes before attempting a metadata write. This property is currently only for metadata writes from the metadata cache. Platforms tested: IRIX64 6.5 (modi4) w/parallel
