* [svn-r9861] Purpose:Quincey Koziol2005-01-241-1/+17
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Add detect vasprintf() routine and use it instead of vsnprintf() when formatting error descriptions if it's available. Added configure test to detect "broken" vsnprintf() implementations which don't return the correct number of character for strings that are too long to fit into the buffer provided (currently a problem on the SGIs and probably the HP). Re-wrote error formatting code in H5Epush_stack() to handle broken vsnprintf() implementations, etc. Platforms tested: IRIX64 6.5 (modi4) h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Koziol2004-09-091-18/+76
| | | | | | | | | | | | | | | | | | | | | | | 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 Lu2004-09-011-121/+81
| | | | | | | | | | | | 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/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

| | | | | | | | | | | | | | | | | | | 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)

* [svn-r7355] Purpose:Quincey Koziol2003-08-131-787/+6
| | | | | | | | | | | | | | | | | | | | | | Code cleanup, etc. Description: Previously (in versions prior to 1.7), there were two locations to modify when an error was added to the library. Now, with the new error API, there were four. Solution: Created a single text file (src/H5err.txt) and a perl script (bin/make_err) which uses the text file to automatically create header files that are included in appropriate places in the library. This means that there is only one file (src/H5err.txt) which needs to be modified when a new error code is added to the library. The automatically generated headers depend on this file and the makefiles will take care of running the perl script to regenerate them when the text file changes, so no user action is required when a new error is added.

| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues.

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.
