* [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... Platforms tested: H5committests (run by hand on burrwhite, arabica, and modi4) Misc. update:
* [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-r6388] Purpose:Quincey Koziol2003-02-101-1/+1
| | | | | | | | | | | | | Update feature Description: Relax collective constraint for API functions which only read metadata from a file. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 w/parallel
* [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. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE
* [svn-r6269] Purpose:Quincey Koziol2003-01-131-1/+1
| | | | | | | | | | | | | Code cleanup Description: Various code cleanups to allow the development branch to be compiled with a C++ compiler (i.e. CC=g++ ) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) C++
* [svn-r6266] Purpose:Quincey Koziol2003-01-101-51/+51
| | | | | | | | | | | | Code cleanup/new feature. Description: Split FUNC_LEAVE into API and non-API specific versions. This allows a solution to compiling this branch with C++, as well as reducing the size of the binaries produced.

* [svn-r6252] Purpose:Quincey Koziol2003-01-091-95/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. 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.

* [svn-r5954] Raymond Lu2002-09-301-2/+7
| | | | | | | | | | | Purpose: a bug fix Description: When a file is opened for a second time, file close degree is supposed to be either the same as the first open, or default as the first open is also default. Platforms tested: Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
* [svn-r5951] Raymond Lu2002-09-301-0/+77
| | | | | | | | | | | 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-r5929] Pedro Vicente Nunes2002-09-181-0/+8
| | | | | | | | | | | | | | Purpose: bug fix Description: memory leak regarding the ID to name buffer Solution: added a new function H5G_free_ent_name that is called on several places of the library Platforms tested: windows 2000 linux, with cpp solaris, with fortran, cpp irix64, with parallel, fortran
* [svn-r5904] Pedro Vicente Nunes2002-08-281-1/+23
| | | | | | | | | | | | | | | | | | | Purpose: Added 'ID to name' support Description: There is a new API function H5Iget_name Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t which has 2 new fields 'name' and 'old_name' A new private function was introduced H5G_ent_copy, that does a deep copy between 2 symbol table entries The test file is getname.c Platforms tested: windows 2000, Linux, Solaris
* [svn-r5879] Raymond Lu2002-08-201-6/+7
| | | | | | | | | Purpose: Design for compact dataset Description: Compact dataset is stored in the header message for dataset layout. Platforms tested: arabica, eirene.
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-9/+6
| | | | | | | | | | | | | | | | 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 Koziol2002-08-091-3/+12
| | | | | | | | | | | | | 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 Koziol2002-08-091-4/+4

* [svn-r5842] Purpose:Quincey Koziol2002-08-081-206/+211
| | | | | | | | | | | | | | | | 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-r5840] Purpose:Quincey Koziol2002-07-311-15/+13
| | | | | | | | | | | | | | Code cleanup Description: Created a new H5I function which combined the some of the functionality of H5I_get_type and H5I_object: H5I_object_verify. Using this new function in the library trims another ~200 lines of code off the library and makes the resulting binaries smaller and faster also. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5832] Purpose:Quincey Koziol2002-07-241-7/+7
| | | | | | | | | | Code cleanup Description: Re-alphabetized header includes. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & C++
* [svn-r5828] Purpose:Quincey Koziol2002-07-231-1/+4
| | | | | | | | | | Code cleanup Description: Make the sieve buffer managed by the free-list code. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5799] Purpose:Quincey Koziol2002-07-151-2/+3
| | | | | | | | | | | | New feature. Description: Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but performs I/O directly with posix sec(2) I/O functions. This driver should _NOT_ be used if the file accessed is not on a parallel filesystem. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
* [svn-r5784] Purpose:Quincey Koziol2002-07-121-91/+100
| | | | | | | | | | | | | | | Bug fix. Description: "strong" file closing feature was re-using free'd memory for objects which were still open in the file. Solution: Used the "dmalloc" tools to determine where the memory was being re-used and re-arranged the code to avoid these cases. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5677] Purpose:Quincey Koziol2002-06-191-19/+2
| | | | | | | | | | | Code improvement Description: Some small code cleanups and took out the code the was turning off the metadata cache for parallel I/O (!) Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5562] Purpose:Quincey Koziol2002-06-101-2/+2
| | | | | | | | | | | Code cleanup Description: Allow H5FD_free to return successfully (but ignore) freeing objects with size 0. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5551] Purpose:Quincey Koziol2002-06-071-2/+2
| | | | | | | | | | | | Bug fix. Description: Added extra check to locations where metadata and "small data" blocks were being returned to the file's list of free space to avoid freeing 0-sized blocks. This should fix the problems in last night's daily tests. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5542] Purpose:Quincey Koziol2002-06-061-0/+31
| | | | | | | | | | | | | | | | | Code cleanup/bug fix Description: Unused space in the file was being "dropped on the floor" when the metadata or "small data" block was moved to a new location in the file and there was unused space in the old block. Solution: Put the space left in the allocation block into the free list of space for the file. This allows it to be [potentially] reused and sometimes allows the file to be smaller. Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5538] Purpose:Quincey Koziol2002-06-051-41/+99
| | | | | | | | | | | | | | | Code improvement. Description: Added boot block and driver info block checksumming feature to the shared file information. This prevents these blocks from being written out multiple times when they haven't changed. This reduces the number of I/O operations which hit the disk for my test program from 15 to 14 (i.e. from 393 to 14, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5536] Purpose:Quincey Koziol2002-06-051-1/+8
| | | | | | | | | | | | | | | | | 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-r5471] Purpose:Quincey Koziol2002-05-291-29/+33
| | | | | | | | | | | | | | | | 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-r5467] Purpose:Quincey Koziol2002-05-281-15/+30
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
