| | | | | | | | | | | | Count). This is needed to avoid a conflict with the Read Context object to be introduced in another Project. No impact on users, since this is a private module, and low for developers as the RC module use is very sparse in the library. Tested with h5committest.
* [svn-r18357] Description:Quincey Koziol2010-03-021-10/+7
| | | | | | | | | | | | | | | | | | | | | | | | Bring r18356 from metadata journaling merge branch to trunk: Converge metadata journaling branch with trunk with a bunch of v1 B-tree changes: - Remove H5ACprivate.h header from H5Bprivate.h header - Revise v1 B-tree client callbacks - Get rid of H5B_serialize() by bringing it into H5B_flush() Tested on: FreeBSD/32 6.3 (duty) in debug mode FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x, w/C++ & FORTRAN, w/threadsafe, in debug mode Linux/64-amd64 2.6 (amani) w/Intel compilers, w/default API=1.6.x, w/C++ & FORTRAN, in production mode Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN, w/szip filter, in production mode Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN, in production mode Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in debug mode Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode
* [svn-r18262] Purpose: Fix bug in b-tree codeNeil Fortner2010-02-161-0/+10
| | | | | | | | | | | | Description: In certain cases, removal of an object in a v1 b-tree would cause the leftmost key in the right neighbor to be overwritten. While this did not pose a problem for group b-trees, with chunked datasets it would overwrite the offset value of the neighbor's leftmost child, causing corruption. Reworked the code to differentiate between b-trees whose children are fundamentally associated with their left key and those who are associated with their right key. Tested: jam, linew, amani (h5committest)
* [svn-r16710] Purpose: Fix bug 1423Neil Fortner2009-04-081-2/+0
| | | | | | | | | | | | | | Description: Versions of the library between 1.3.0 and 1.6.3 have a bug which prevents them from opening any file that does not have the root group's symbol table information cached in the root group's entry in the superblock. Prior to 1.8 this was not an issue as this information was always cached. However, 1.8.0 stopped writing this information (which is not required by the file format specification), and these older versions can therefore not read files created or last written by versions 1.8.0 to 1.8.2. This fix modifies the library to once again add this information to the superblock (when using the old file format). Tested: jam, linew, smirom (h5committest)
* [svn-r16594] Purpose: fix bug 1189Neil Fortner2009-03-231-0/+4
| | | | | | | | | | | Description: Some files apparently exist in the wild which have corrupt symbol table messages on the root group. These files can be opened by 1.6 (which uses the cached information in the superblock) but not by 1.8. This patch fixes 1.8 and 1.9 so they can now open these files, and will correct them if necessary. Also fix some potential (rare) problems with array datatype versions. Tested: jam (parallel; h5committest not working on linew or smirom)

* [svn-r11686] Purpose:Quincey Koziol2005-11-071-13/+29
| | | | | | | | | | | | | | | | | | | New feature Description: Add in baseline "object copy" code from Peter [in the form of a new API routine: H5Gcopy()]. There's still some work to do (like handling variable- length datatypes and possibly support for references) and it hasn't been tested on mounted files yet, but the core functionality is there and working correctly. I've also got a set of patches to update the 1.6 branch with tweaks to keep the branches mostly in sync, but Elena will kill me if I import them before the 1.6.5 release is out... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committested

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | Bug fix/code cleanup Description: Clean up raw data I/O code to bundle the I/O parameters (dataset, DXPL ID, etc) into a single struct to pass around through the dataset I/O routines, since they are always passed together, until very near the bottom of the I/O stack.

| | | | | | | | | | | | | | | | | Code optimization Description: Re-work the insertion of a new child into an existing node, to exploit some speedups for adding the rightmost child, since this is a very common case when appending records to an unlimited size dataset. Also, hoist the checks for the tree's 'K' value into a field in the shared information about the tree, instead of re-calculating them all the time.

* [svn-r8853] Purpose:Quincey Koziol2004-07-101-1/+14
| | | | | | | | | | | | | | | | | | | | Code optimization Description: Refactor B-tree code to extract all common information for a B-tree into a shared structure that is pointed to by all the nodes in tree (instead of being included in each node). Also re-order B-tree node comparison checks for chunked datasets to check for >= the upper node first, since the comparison is a bit "heavy" and this check is more likely to succeed when you are adding records to the dataset. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest (also, recent h5dump commits have broken testing...)
* [svn-r8823] Purpose:Quincey Koziol2004-07-071-0/+3
| | | | | | | | | | | | | | | Code optimization Description: Since the raw B-tree nodes are the same size and only used when reading in or writing out a B-tree node, move raw B-tree node buffer from being per node to a single node that is shared among all B-tree nodes of a particular tree, freeing up a lot of space and eliminating lots of memory copies, etc. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

* [svn-r7080] Purpose:Quincey Koziol2003-06-231-6/+7
| | | | | | | | | | | | | | | | | Bug fix (backward compatibility) Description: Changes we've made during development of the 1.5.x branch had broken the feature of allowing user's callbacks to H5Giterate to return a value through the library back to the application which called H5Giterate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r5230] Purpose:Quincey Koziol2002-04-231-14/+6
| | | | | | | | | | | | | | | | | Code cleanup Description: Clean up the H5B_iterate code to not have a single hard-wired iterator for each interface which uses a B-tree, instead accept a function pointer which determines the callback function. This allows additional iterator callbacks to be defined without requiring additional H5B functions to be created. In that spirit, remove the H5B_prune_by_extent call and convert the H5F_istore callback routine for it into a callback routine for H5B_iterate. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4355] Purpose:Quincey Koziol2001-08-141-7/+7
| | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
