Changed malloc and free to HDmalloc and HDfree. Removed unused dtype var. r17878: Error 265: Uninitialized mem_space set to -1. Changed malloc and free to HDmalloc and HDfree. Error 267: Uninitialized smspace set to -1. Changed malloc and free to HDmalloc and HDfree. r17879: Error 242: Uninitialized aid set to -1. Error 243: Uninitialized sid set to -1. Uninitialized tid set to -1 for consistency r17880: Error 242: reinitialized aid to -1 after close to be ready for reuse. Error 243: reinitialized sid to -1 after close to be ready for reuse. reinitialized tid to -1 for consistency after close to be ready for reuse. r17881: use valgrind to check there is a memory leak. The fix is to free ptrstr in line 5838 at xml_dump_group() of h5dump.c after it is used. run the valgrind after the fix, no memory leak for that part of the code. r17882: Fix Coverity items 256 and 269. r17883: Error 222-230: initialized hid_t vars to -1 after close to be ready for reuse. Also added H5Tclose for tid in gent_bigdims r17884: Bug fix (Coverity run2, view 23, dead code) (this is pair-program done by Albert, Elena and Larry). Confirmed and fixed the deadcode in hyperslab read branch of function diff_datasetid. (Discovered other bad code that diff_datasetid() should be recoded. Bug 1693 is entered for this.) r17906: Fix Coverity item 260. r17907: 262: Initialized hid_t's dtype, dtype_tmp and file to -1. Initialized H5T_t * dt to NULL. r17908: Fix Coverity item 261. r17909: Fix Coverity item 248. r17910: Revise fix for Coverity item 248. r17911: Resolved coverity issues #s 263, 162, 163, 164. All issues in dsets.c. Initialized fid and did hid_t's. filter_corrupt function was returning in the middle of an if statement, bypassing free calls. Updated error handling to free buffers and hid_t's appropriately. r17912: (done by Larry and Albert) Cleanup Coverity view warnings (#231-241) about using uninitialized variables. Initialized all of them. r17913: Resolved issue 251 and 264. Initialized tid2 to -1 and initialized buffers that were freed in case of an error. r17914: Resolved coverity issues 66, 220, and 221: 66: Negative Return assignment ignored 220,221: Initialized hid_t's. r17915: Fix Coverity item 247. r17916: Fix Coverity item 246. r17917: Fix Coverity item 245. r17918: Fix Coverity item 244. r17919: Coverity Issue #84: Moved asserts in H5T_cmp to the top of the function, and converted them to HDassert. Coverity complaining about using potentially NULL pointer without checking it. Want to see if Coverity will accept Assertions as acceptable checking before using the value.

* [svn-r16609] Bug fix (#1161): When a family file created with v1.6 library ↵Raymond Lu2009-03-241-5/+12
| | | | | | | | | | | is opened and closed with v1.8 library, v1.8 library writes the driver info block in the superblock. But v1.6 doesn't write it. This caused the data after the superblock to be overwritten. The solution is to use a flag to indicate when the original file doesn't have the driver info, v1.8 library doesn't write it either. Tested on jam. I have some trouble to access smirom and linew using h5committest.

Generally any id visible to the application gets placed in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref, H5I_register, H5I_clear_type, and a few other functions, to specify whether the operation(s) being performed on the id(s) are due to the application (TRUE) or not (FALSE).

| | | | | | | | | | | | | Description: After recent fix of family driver bug(#213), some failure was discovered on sol and kelgia in daily test. Family files can't be opened by hdf5/tools/misc/repart_test.c. It turned out to be the destination size of "off_t" type wasn't passed in through H5Pset() correctly. Solution: In tools/misc/h5repart.c, copy the destination size to a variable of "hsize_t" type and pass in to H5Pset(). Platforms tested: sol and kelgia where the failure was discovered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Description: See details from Bug #213. Family member file size wasn't saved anywhere in file. When family file is opened, the first member size determine the member size. Solution: This is the fourth step of checkin. A test suit is added for h5repart, including a program to generate the test files, a script file to run h5repart, and a program to verify repartitioned files can be opened by the library. There's a change from the first step of checkin. Family name template is no longer saved in the superblock because different pathname can make the name different. In the third step of checkin, h5repart has been modified. If h5repart is used to change the size of family member file, the new size(actual member size) is saved in the superblock. In the second step of checkin, multi driver is checked against the driver name saved in superblock. Wrong driver will result in a failure with an error message indicating multi driver should be used. This change includes split driver because it's a special case for multi driver. In the first step of checkin. Family member size and name template(unused at this stage) are saved in file superblock. When file is reopened,the size passed in thrin superblock. A different size will trigger a failure with an error message indicating the right size. Wrong driver to open family file will cause a failure, too. Platforms tested: h5committest and fuss. Misc. update: MANIFEST

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

| | | | | | | | | | | | | | | | | | Purpose: Correction to previous bug fix. This checkin is mainly to let user test his program. Description: For family driver bug(#213), the previous fix was imperfect. The problem was when user create family file, the member size information wasn't saved in file. When the file was re-opened, the library simply use the size of 1st member file as member size. Solution: When file is re-opened, member size passed in from access property is checked to see if it's reasonable. If there is only 1 member file, member size can't be smaller than current member size. If there are at least 2 member files, member size can only be equal to the 1st member size. Platforms tested: h5committest and fuss
* [svn-r9531] Purpose: Bug fix(#213)Raymond Lu2004-11-161-9/+16
| | | | | | | | | | | | | Description: H5Pset_fapl_family sets family member size only for creating new file. The file doesn't keep this size information. When the file is re-opened, the size of first member file is used as the member size. Solution: Assume user knows the original member size and sets it through H5Pset_fapl_family. That will be the member size. User can pass in value 0 as member size if he doesn't know the original member size. Library will choose the size of current first member size as the member file size. Platforms tested: h5committest and fuss.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

| | | | | | | | | | | Purpose: New API functions Description: Added API functions to return pointer to low-level file handle (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list setting functions(H5Pset_family_offset and H5Pset_multi_type). Platforms tested: Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-3/+3
| | | | | | | | | | | | | | | | Code cleanup Description: Combined H5P_isa_class and H5I_object functionality into a new internal H5P API function: H5P_object_verify, which checks that a property list is the appropriate class and then returns the property list object associated with the property list ID. This reduces the source code by about 200 LOC and trims the library binary some more. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5867] Purpose:Quincey Koziol2002-08-091-5/+27
| | | | | | | | | | | | | 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-r5866] Purpose:Quincey Koziol2002-08-091-3/+5
| | | | | | | | | | Code cleanup Description: Cleaned up a few warnings from compiling with --disable-hsizet on Linux Platforms tested: Linux 2.2.x (eirene)
* [svn-r5842] Purpose:Quincey Koziol2002-08-081-37/+72
| | | | | | | | | | | | | | | | 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-r5536] Purpose:Quincey Koziol2002-06-051-0/+1
| | | | | | | | | | | | | | | | | New feature. Description: Added a "small data" block allocation mechanism to the library, similar to the mechanism used for allocating metadata currently. See the RFC for more details: http://hdf.ncsa.uiuc.edu/RFC/SmallData/SmallData.html This reduces the number of I/O operations which hit the disk for my test program from 19 to 15 (i.e. from 393 to 15, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5484] Raymond Lu2002-05-291-14/+10
| | | | | | | | | | | | | Purpose: Bug Fixing Description: In H5FD_family_write and H5FD_family_read, size_t is checked against hsize_t for overflow, which fails on IA32 architecture machine supporting large files. Solution: Use temporary variable which won't pass the limit of size_t. Platforms tested: Linux 2.4(platinum) and IRIX64 6.5(modi4)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-18/+18
| | | | | | | | | | | | | | | | 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-r5440] Purpose:Quincey Koziol2002-05-201-3/+3
| | | | | | | | | | | New feature Description: Add 'closing' parameter to H5FDflush and VFL "flush" functions, per http://hdf.ncsa.uiuc.edu/RFC/VFLFlush/VFLFlush.html Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5403] Purpose:Quincey Koziol2002-05-131-2/+2
| | | | | | | | | | Back out changes. Description: Back out changes to VFL 'flush' API function, pending review. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5393] Purpose:Quincey Koziol2002-05-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | New Feature Description: The VFL flush function is called immediately before a file is closed. This can cause duplicate syncronization actions to occur, if the VFL close function also performs them. Solution: Added 'closing' parameter to VFL 'flush' operation. This allows the VFL flush function to bypass operations that will be duplicated within the VFL close function. Additionally, use the 'closing' parameter to bypass calls to MPI_File_sync() when set. Since MPI_File_close() also syncronizes the file, this avoids the terrible performance hit taken when calling MPI_File_sync() as the file is closing. Platforms tested: IRIX64 6.5 (modi4)
