* [svn-r26322] Merge of r26246 and r26249 from the trunkDana Robinson2015-02-261-0/+1
| | | | | | | | | | Fixes a bug in the bin/trace script that prevented API calls which return a pointer from receiving TRACE macros. Also removes the NO TRACE warnings, which we decided were distracting and unnecessary. Tested on: jam (minor change)
* [svn-r25529] Purpose:Dana Robinson2014-08-111-0/+4
| | | | | | | | | | | | Merged r25508 from the trunk. Adds a check that ensure the page_size parameter in H5Pset_core_write_tracking is not zero. This ensures that the behavior matches the text in the reference manual. Tested on: 32-bit LE linux (jam), tested with make check-vfd. This is a very minor change and does not require full testing.
* [svn-r25109] Description:Quincey Koziol2014-04-251-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bring r25084, 25088, 25092, 25097 from trunk to 1.8 branch: r25084: Begin process of migrating from using property list IDs internally to the library to using the internal generic property list data structure. r25088: Introduce "file I/O info" struct, to hold file & dxpl pointers, and start propagating up through library. r25092: More migration to using H5F_io_info_t pointers and away from using property list IDs internally. Also, clean up some compiler warnings in the cache code. r25097: Make progress toward moving from DXPL IDs to property list structures within the library. Also move the signature location code from the H5F package to the H5FD package, where it's a better fit. Also, clean up some more compiler warnings along the way. Tested: Mac OSX/64 10.9.2 (amazon) w/C++, FORTRAN & parallel (h5committested on trunk)
* [svn-r25033] Purpose:Dana Robinson2014-04-121-2/+91
| | | | | | | | | | | | | | | | | | Merged r24993 from the trunk. Adds core VFD write tracking functionality. When enabled, the core VFD will track dirty regions of the file and only write out the changed regions. The new H5Pget/set_core_write_tracking() API call controls this feature. A new "core_paged" VFD target was added to the check-vfd target in test/Makefile.am that runs all tests with the new write tracking functionality. Tested on: 32-bit LE linux (jam) 64-bit LE linux (koala) 64-bit BE linux (ostrich) Each platform was tested with HDF5_DRIVER set to "core" and "core_paged". Jam was also tested with the standard sec2 driver.

| | | | | | | | | | | | | | Bring r22758 from trunk to 1.8 branch: Bring generic improvements from encode/decode property list branch to the trunk. This includes a better version of the property list comparison routine, cleaned up compiler warnings, and some cleaned up property list callbacks. Also, started on changes to clean up parallel test output, so that it doesn't report successful tests from each process. Tested on: Mac OSX/64 10.7.4 (amazon) w/debug, GCC 4.7.x, FORTRAN, C++, threadsafe and parallel (h5committested on trunk)
* [svn-r22708] Description:Quincey Koziol2012-08-221-171/+37
| | | | | | | | | | | | Bring r22707 from trunk to 1.8 branch: Bring back some more cleanups from the plist_encode_decode branch, clean up some formatting and compiler errors, and add a few more property comparison routines that we've skipped implementing in the past. Tested on: Mac OSX/64 10.7.4 (amazon) w/debug (Too minor to require h5committest)
* [svn-r22682] Description:Quincey Koziol2012-08-151-204/+105

* [svn-r21925] Description:Quincey Koziol2012-02-101-82/+82
| | | | | | | | | | | | | | Bring r21919-21924 from trunk to 1.8 branch: cleanup FUNC_ENTER macros, etc. Also removed Subversion mergeinfo tags from a few directories and files. These are artifacts from non-root merges using pre-1.6 Subversion clients. (This should fix the problem of unchanged directories looking "changed" during checkins.) Tested on: Mac OSX/64 10.7.3 (amazon) w/debug & production (daily tested on trunk)

* [svn-r13856] H5FDwindows.h is included in the hdf5.h but we didn't put it ↵MuQun Yang2007-06-121-0/+2
| | | | | | | | | | | | | | | | into Makefile.am un der /src. So when gmake check-install is run for HDF5 examples, it will fail. Th e fix is to include a macro #ifdef H5_HAVE_WINDOW around #include H5FDwindows.h so that H5FDwindows.h will only be included on windows, not on other platforms. We've fixed with the same way for other source code that includes H5FDwindows.h. This has been tested with h5committest. However, it takes a few hours to test all tests and except kagiso. Tests on linew and smirom cannot finish. It takes forever for the fheap test. And for parallel test at kagiso, ph5diff test seems to be hanged. I think all of our changes will only affect windows. So in order not to block other developers to check in their code, we just go ahead to check our changes. Kent Yang

| | | | | | | | | | | | running on kagiso. The static szip libraries are working as intended, but when shared szip libraries are present and intended for use they cannot be opened. A check has been implemented to test if shared szip libraries are functional on current platform. If they are not, and the user is trying to use them, szip is now disbaled and the user is informed. This issue occurs on kagiso, and the resolution was tested on kagiso.

* [svn-r12842] Description:Quincey Koziol2006-11-021-19/+417
| | | | | | | | | | | | | | | | Refactor generic property list initialization code to put property list specific routines in property list modules, instead of scattered to the four winds. Also, introduce property list class initialization objects, to make adding new property list classes in the library easier. Fix daily test failure by using H5Pget_elink_prefix() API routine instead of looking at the "raw" generic property list information. Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/build-all & 1.6 compat

Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10847] Purpose: Bug fixRaymond Lu2005-06-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | Add API calls allowing user control of the metadata cache. Description: Prior to this update, the metadata cache was not configurable from outside the library.

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