* [svn-r7725] Purpose:Quincey Koziol2003-10-241-74/+55
| | | | | | | | | | | | Code cleanup Description: Refactored handlier of VFL drivers in file access and data transfer property lists in order to simplify and unify the code dealing with them. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7626] Purpose:Quincey Koziol2003-10-141-1/+3

* [svn-r7559] Purpose:Quincey Koziol2003-10-071-0/+39
| | | | | | | | | | | | | | Add feature Description: Add H5Fget_freespace() routine, to check the amount of free space in a file. This information is only valid until the file is closed currently, however (until we start recording the free space information in the file itself). Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7498] Purpose:Quincey Koziol2003-09-191-19/+20
| | | | | | | | | | | Code cleanup Description: Clean up various warnings and parameter mis-matches, etc. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to need h5committest
* [svn-r7495] Purpose:Bill Wendling2003-09-191-5/+0
| | | | | | | | | | | | | | | | Removed Dead Code Description: Some of the FPHDF5 code was dead (I thought it'd be useful at one point, but was wrong). Solution: Removed Platforms tested: Linux (FPHDF5 specific. No need for h5committest) Misc. update:
* [svn-r7494] Purpose:Quincey Koziol2003-09-191-25/+73
| | | | | | | | | | | | | | | | | | Bug fix Description: Buffer for decoding superblock's driver information was too small when using some VFDs (like the multi-file VFD). Also made FPH5 code more portable and obvious when it's broadcasting the superblock from the captain process to the other clients. Solution: Allocate the buffer for the driver information dynamicly Platforms tested: Copper No h5committest because it's already working on other platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update Description: A lot of modifications for the FPHDF5 stuff: H5AC.c H5ACprivate.h - Removed AC_find (it's replaced with AC_protect and AC_unprotect). Added flushing if it's an FPHDF5 driver and we're doing an AC_set or AC_unprotect with the dirty flag set. H5B.c - Split up the B_flush function into different functions since the one function was doing serialization which is better left as a separate entity. H5D.c - Removed some FPHDF5 code that was incorrect H5F.c - Split up the F_flush function so that it no longer allocates file space. Created new functions (F_init_superblock, F_read_superblock, and F_write_superblock) for greater modularity and so that the FPHDF5 non-captain processes can read the superblock after the captain process writes it. H5FD.c - Error message correction. H5FDfphdf5.c - Removed MPI barrier call that wasn't needed. H5FPclient.c H5FPserver.c - Modified so that if a process requests data that isn't exactly aligned, we can return it if we have the block that contains the requested address. H5G.c H5Gent.c H5Gnode.c H5HL.c H5HLpkg.h H5HLprivate.h H5Oefl.c - Removed the H5HL_peek function since it was doing a (now unsafe) holding of the information in the cache. Replaced with protect and unprotect calls. H5TB.c - Error fix. The TB_dless function wasn't working properly. H5Gstab.c - Format change. H5err.txt H5Edefin.h H5Einit.h H5Epubgen.h H5Eterm.h - Added new error code. Platforms tested: Modi4 (paralle, Fortran) Sol (Fortran) Linux (C++, Fortran) Copper (Parallel, Fortran) Misc. update:
* [svn-r7473] Purpose:Quincey Koziol2003-09-151-60/+129
| | | | | | | | | | | | | | Code cleanup & optimization Description: Split superblock initialization and space allocation out from writing the superblock information to disk, which makes the code much cleaner and easier to understand and also allows FPHDF5 to have a fully completed superblock to Bcast to other (non-caption) processes. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7471] Purpose:Bill Wendling2003-09-121-536/+627
| | | | | | | | | | | | | | | | | | | | | Update Description: The F_open and F_flush functions had a lot of cruft in them. The F_flush was being used as a way to allocate the superblock. The F_open had a bunch of code in there to read and serialize the superblock. Solution: Moved these out into their own functions. Platforms tested: Modi4 (parallel, Fortran) Copper (parallel, Fortran) Verbena (Fortran, C++) Sol (Fortran) Misc. update:
* [svn-r7457] Purpose:Quincey Koziol2003-09-101-25/+28
| | | | | | | | | | | | | | | | | | | | Bug fix. Description: Correct bug where a file opened twice, once with read-write permission and once with read-only permission would cause closing the file with the read-only file ID to fail because it was trying to flush information out of the file. Solution: Check the permissions on file IDs that are being closed and only flush when the particular file ID was opened with write permission. Platforms tested: FreeBSD 4.9 (sleipnir) too small to need h5committest Misc. update:
* [svn-r7441] Purpose:Quincey Koziol2003-09-041-2/+9
| | | | | | | | | | | | | | | | | Bug fix Description: The VFL driver ID in a file's access proprty list wasn't being reference counted correctly, causing the VFL driver to get prematurely closed after several calls to "H5Pget_access_plist->H5Pclose". Solution: Increment VFL driver ID reference count when copy of file's access property list is made in H5Pget_access_plist() Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7426] Purpose:Quincey Koziol2003-08-281-5/+50
| | | | | | | | | | | | | | | | | Bug fix Description: When datasets are deleted from a file, they are removed from the sieve buffer, but instead of invalidating only the part of the sieve buffer affected, the sieve buffer code would throw away the entire sieve buffer, potentially including other raw data in the buffer that hadn't been written to disk yet. Solution: Improve the sieve buffer clearing code to handle partial invalidations. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7384] Purpose:Quincey Koziol2003-08-191-7/+11

* [svn-r7367] Purpose:Bill Wendling2003-08-151-12/+22
| | | | | | | | | | | | | | | | | | | Update Description: Added an extra flag to the clear functions that triggers a "destroy" of the object being cleared if necessary. This is a fix for the FPHDF5 stuff which had an object sticking around after it was cleared. (In FPHDF5, some processes are in charge of destroying the object, but all processes might actually allocate the object.) Platforms tested: AIX (Copper: Fortran & C++) Linux (Verbena: Fortran & C++) IRIX (Modi4: Parallel & Fortran) (Sol is down) Misc. update:
* [svn-r7362] Purpose:Quincey Koziol2003-08-141-1/+14
| | | | | | | | | | | | | Bug fix Description: Allow a user block to be "inserted" in front of a file (probably by writing a validly-sized userblock to a new file and then appending another HDF5 file to the new file). Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r7315] Purpose:Quincey Koziol2003-08-081-38/+1

* [svn-r7232] Purpose:Quincey Koziol2003-07-161-63/+97
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When a non-default indexed storage B-tree internal 'K' value is set by the user, the chunked datasets created in that file (until it is closed) use the user's 'K' value and the data can be accessed correctly, but the 'K' value is not stored in the file. However, once the file is closed and re-opened, the non-default 'K' value is lost and the data in the chunked datasets will not be able to be accessed correctly. Solution: Store the indexed storage B-tree internal 'K' value in the superblock. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7201] Purpose:Quincey Koziol2003-07-101-4/+4
| | | | | | | | | | | | | Code cleanup Description: Finish converting the B-tree 'K' values to use unsigned integers, rather than signed ones, since negative amounts of entries in a B-tree node aren't meaningful. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7189] Purpose:Quincey Koziol2003-07-091-115/+5
| | | | | | | | | | | Code cleanup Description: Break some of the "debugging" routines into their own module, so they aren't pulled into every executable, which certainly isn't going to use them. Platforms tested: h5committested
* [svn-r7175] Purpose:Quincey Koziol2003-07-071-2/+2
| | | | | | | | | | | | | | | | | | Bug fix Description: Boot block checksum was being used instead of file driver info checksum in one calculation. Also, the offset of the file driver info was hard-coded to the end of the superblock, instead of using the file driver offset variable. Solution: Changed to use file driver checksum and file driver offset variable. Platforms tested: FreeBSD 4.8 (sleipnir) too small for h5committest
* [svn-r7146] Purpose:Albert Cheng2003-07-031-1/+1
| | | | | | | | | | | | | | | update for release Description: Set the version information to 1.6.0-pre1 to get ready for v1.6 release. (Not sure why H5F.c got changed--probably done gmake automatically during testing.) Platforms tested: h5committested. Misc. update:
* [svn-r7072] Purpose:Quincey Koziol2003-06-201-15/+16
| | | | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: The H5F_get_objects_cb was returning SUCCEED (i.e. 0) to indicate that the ID iterator should exit early, but the ID iterator needs a non-zero return from a callback to exit early. Also, track change to ID iterator "operator data" to be non-const Solution: Changed H5F_get_objects_cb() to return "TRUE" instead, to indicate an early exit for the ID iterator. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r7057] Purpose:Quincey Koziol2003-06-181-90/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix, refactored code Description: Fixed closing objects for "strong" file degree, which previously would sometime attempt to close the same object twice (when a named datatype and a dataset which used it were both left open before the file was closed). Stopped datatype iteration from querying for the group entry of non-named datatypes. Added attributes to the list of objects that can be queried by H5Fget_obj_count and H5Fget_obj_ids, since they can hold open a file also. Took a suggestion from Robb to return the number of open objects in the return values of H5Fget_obj_count and H5Fget_obj_ids. Also, added a "max_objs" parameter to the H5Fget_obj_ids function, so that it can work well with staticly allocated arrays. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
* [svn-r6878] Purpose:Quincey Koziol2003-05-151-15/+18
| | | | | | | | | | | Code cleanup Description: Limit the scope on more function prototypes/macros/typedefs. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6837] Purpose:Quincey Koziol2003-05-081-1/+1
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested
* [svn-r6776] Purpose:Pedro Vicente Nunes2003-04-291-3/+0
| | | | | | | | | | | | | | | removed and change comments Description: removed the modification comment about the while loop, it is not sufficiently important to be there changed the "Id to name" comment in the test description, it was incorrecly about other thing Solution: Platforms tested: none , just comments Misc. update:
* [svn-r6724] Purpose:Bill Wendling2003-04-211-0/+10
| | | | | | | | | | | | | | | Commenting Description: Added comments to the H5Fget_access_plist function to remind people that if they are going to be overwriting a value in the plist which was originally opened and inserted into the plist, then it should be closed before overwriting that value. Platforms tested: Modi4 (Only comment change, so no h5committest needed). Misc. update:
* [svn-r6721] Purpose:Pedro Vicente Nunes2003-04-211-2/+6
| | | | | | | | | | | | | | | | | | bug fix Description: in the close strong case in H5F_close there was a do..while loop that executed when nfiles==0, calling malloc(0) this was causing a failure in the close call in Code Warrior, that returns 0 in the call pt=malloc(0) Solution: replaced with a while loop (checks the condition before executing) Platforms tested: code warrior, linux Misc. update:
* [svn-r6719] Purpose:Bill Wendling2003-04-211-0/+8
| | | | | | | | | | | | | | | | | | | | | Bug Fix Description: A resource leak happened if the H5Fget_access_plist() function was called. What was happening: the driver ID and info parts of the property list copied in H5Fget_access_plist were being overwritten, but those properties were copied initially, so we lost information. Solution: Before copying over those values, call the H5F_acs_close() function to close those values. Platforms tested: Modi4 (Parallel & Fortran) Arabica (Fortran) Verbena (Fortran & C++) Misc. update:
* [svn-r6672] Purpose:Bill Wendling2003-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: When calling "H5F_get_access_plist" after setting the FAPL to a multi driver, and then trying to get the multi driver back, it resulted in returing a "NULL" value instead of the driver. Solution: The stuff at the location pointed to by the driver was being stored into the property list and not the pointer to the driver itself. Changed the "H5P_set" code so that it stores the pointer instead of the driver...(Added an "&" in from of the "driver_info" variable). Platforms tested: Arabica (Fortran) Burrwhite (Fortran & C++) Modi4 (Fortran & Parallel) Misc. update:
* [svn-r6648] Purpose:Quincey Koziol2003-04-141-2/+41
| | | | | | | | | | | | | | | | | | New code. Description: Added internal routine to clear the sieve buffer if it overlaps a address- length range in the file. This is used currently to clear the sieve buffer when an object is deleted from the file. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ Linux 2.4 (burrwhite) w/FORTRAN Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/parallel & FORTRAN (h5committest not run due to my ongoing difficulties with C++ on burrwhite).
* [svn-r6556] Purpose:Bill Wendling2003-04-011-26/+49
| | | | | | | | | | | | | | | | | | | Update & Bug Fix Description: The "free" protocol was missing. Added that to the server side. When doing a "create" of a file (with no other data structures created), the freespace in the file wasn't being reclaimed. Solution: After adding the free protocol, we put the burden of running through the FD_free function on the SAP instead of each client. Platforms tested: Linux Misc. update:
* [svn-r6527] Purpose:Bill Wendling2003-03-271-53/+24
| | | | | | | | | | | | | | | | | | | | | | | Bug Fix & Update Description: FPHDF5 was creating files which didn't have the EOA field in the superblock set correctly. It turns out that the SAP was keeping this information to itself instead of giving it to the client processes. Naughty SAP! Solution: Have the SAP send this information back to the clients so that they can update the superblock as necessary. This now creates a file (with just the root group) that looks correct! Only problem is that there's extra file space being allocated. Also, at program termination, there's an infinite loop...

* [svn-r6519] Purpose:Quincey Koziol2003-03-221-29/+29
| | | | | | | | | | | | | Bug fix/code cleanup/new feature Description: Fix h5debug to work correctly again, with all the changes over the past few months. Improved and cleaned up debugging output available in h5debug. Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6514] Purpose:Bill Wendling2003-03-201-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | Bug fix and Update Description: From Quincey's comments on the code I checked in last night: - In H5F_close call, the "private" processes should call the H5F_flush with the "CLEAR_ONLY" flag. - There's no need for a special case for FPHDF5 in the FD_real_alloc function since FPHDF5 doesn't define an alloc function. - The return type of H5Pset_fapl_fphdf5 should be herr_t instead of hid_t. I don't know how it got that way in the first place. - The variable names for MPI types and the structure typedefs should be switched: H5FP_request/H5FP_request_t to H5FP_request_t/H5FP_request and so on. - In the H5FP.c module, I was commiting the H5FP_request MPI datatype but using the wrong offset field... Platforms tested: Linux...will test on others, but these are mostly FPHDF5 changes. Misc. update:
* [svn-r6505] Purpose:Bill Wendling2003-03-191-49/+157
| | | | | | | | | | | | | | | | | Update Description: Have the FPHDF5 module initialized on startup. Have only the captain process perform certain functions (like flushing during an F_close call or allocating the superblock). H5Fistore needed a few checks to see if it was working with an FPHDF5 driver. Done similarly to how MPI and MPIPOSIX drivers are checked.. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6497] Purpose:Quincey Koziol2003-03-191-12/+12
| | | | | | | | | | | | | | | | | | | Finish code cleanup Description: Wrap up the conversion of H5F_flush's multiple boolean flags into a single bitfield of flags by pushing the flags down into the H5AC_flush and H5F_istore_flush routines. Also, changed the flags from H5_FLUSH_<foo> to H5F_FLUSH_<foo> to be more consistent with rest of library. And reverted the changes to H5FDflush and H5FD_flush routines. Platforms tested: FreeBSD 4.7 (sleipnir) Solaris 5.8 (sol) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6496] Purpose:Bill Wendling2003-03-191-69/+122
| | | | | | | | | | | | | | | | | | | | | | Refactoring of Flush Logic Description: The Flushing logic passed in multiple flags to indicate what type of flush it was: closing, invalidate, alloc only. This made extending the function of the flush logic to handle other flags annoying. Solution: I changed it to be just one bitmasked flag to indicate what type of flushing to do. I also added the CLEAR_ONLY flag, which will be used in the FPHDF5 stuff. Platforms tested: h5committest doesn't work for me (my environment isn't setup on the other machines I guess). I tested it manually: Linux parallel & C++ Sol Fortran Modi4 parallel & Fortran.

* [svn-r6387] Purpose:Quincey Koziol2003-02-101-49/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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? FreeBSD 4.7 (sleipnir) serial & parallel Solaris 2.6 (baldric) serial
