* [svn-r8648] Purpose:Quincey Koziol2004-06-101-5/+3
| | | | | | | | | | | | | Code optimization Description: Eliminate some operations through temporary variables in H5F_addr_encode. Eliminate some redundant memset()'s of structures that will be completely overwritten in the variable-length datatype code. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8613] Purpose:Quincey Koziol2004-06-051-120/+264
| | | | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) h5committest Misc. update:
* [svn-r8600] Purpose:Quincey Koziol2004-05-311-3/+3
| | | | | | | | | | | | | Code optimization Description: Don't recompute the internal index value for looking up the chunk in the hash table, just use the value already computed from iterating through the chunks. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checkpoint checkin of FP bug fixes. FP is still quite buggy, but I must go deal with other matters. Description: Fixed two major bugs: 1) H5FPserver.c was clobbering meta data in its care. 2) H5FPserver.c was allocating the same space multiple times, causing both data and meta data corruption. Also made minor fixes, added debugging code, and familiarized myself with the FP code. All development work with FP enabled was done on Eirene. On this platform, FP now passes its test reliably with up to 9 processes. At 10 processes it seg faults every time. I haven't looked into this issue. There are also several known locking bugs which have to be fixed. However, they are of sufficiently low probability that I didn't bother with them on this pass. FP has not been tested with deletions -- this should be done. Also, need to test FP chunked I/O. Solution: 1) Modified cache in H5FPserver.c to merge changes correctly. Found and fixed a bug in H5TB.c in passing. 2) Multiple space allocation was caused by a race condition with set eoa requests. Most of these eoa requests appeared to be superfluous, so I deleted them. Those issued during the superblock read seemed necessary, so I inserted a barrier at the end of the superblock read, to prevent races with allocations. Platforms tested: h5committested
* [svn-r8287] Purpose:Quincey Koziol2004-03-301-1/+1
| | | | | | | | | | | | | | Bug fix/code cleanup Description: Copy Robb's feature in SSlib that checks that the name of the function used in the FUNC_ENTER macro is actually the name of function. Fixed a bunch of typos & copy-n-pasto's for functions with incorrect names. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8134] Purpose:Quincey Koziol2004-01-311-0/+1
| | | | | | | | | | | | | | | | Code cleanup Description: Add destructor to match constructor fr VFLs when they are shut down by the library. Solution: Added H5FD_*_term() routines to "undo" changes made in H5FD_*_init() routines. Platforms tested: IBM p690 (copper) too minor to require h5committest
* [svn-r8126] Purpose:Quincey Koziol2004-01-311-22/+8
| | | | | | | | | | | | | | | | | Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
* [svn-r8038] Purpose:Quincey Koziol2004-01-081-33/+25
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When two property lists are compared, the H5Pequal routine was just comparing the raw information for the property values. This causes problems when the raw information contains pointers to other information. Solution: Allow a 'compare' callback to be registered for properties, so that a user application get perform the comparison itself, allowing for "deep" compares of the property value. This was exported to the H5Pregister & H5Pinsert routines in the development branch, but not the release branch. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-30/+30
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)
* [svn-r7860] Purpose:Quincey Koziol2003-11-201-0/+2
| | | | | | | | | | | | | | | | | Bug fix Description: Our previous "optimization" of metadata writing which only wrote metadata from one process was abusing MPI-I/O and after some consultation with Rob Ross and Rajeev Thakur, Albert & I have come up with a solution... Solution: Instead of only writing from one process, issue a collective write operation with all processes, for metadata writes. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7803] Purpose:Quincey Koziol2003-10-311-3/+3
| | | | | | | | | | | | Minor code cleanup Description: Fixed up comments, made the H5I_get_file_id() routine static, removed H5Gprivate from including itself... Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7801] Purpose: added featureRaymond Lu2003-10-311-2/+36
| | | | | | | | Description: more feature to H5Iget_file_id(). If file ID is closed, it can still return an ID given object ID. Platforms tested: h5committest
* [svn-r7786] Purpose:Quincey Koziol2003-10-291-1/+0
| | | | | | | | | | | | Code cleanup & add a feature Description: Added support for querying the file ID of named datatypes to new H5Iget_file_id function. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest

* [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-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

* [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.
* [svn-r7489] Purpose:Bill Wendling2003-09-181-55/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
| | | | | | | | | | | Code cleanup Description: More linting... Platforms tested: FreeBSD 4.8 (sleipnir) too minor to need h5committest

| | | | | | | | | | | Code cleanup Description: Various cleanups resulting from running lint tool over H5F.c source module Platforms tested: FreeBSD 4.8 (sleipnir) too minor to require h5committest
* [svn-r7372] Purpose:Quincey Koziol2003-08-151-0/+6
| | | | | | | | Added some comments, etc. Platforms tested: FreeBSD 4.8 (sleipnir) too trivial for h5committest
* [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
| | | | | | | | | | | | Code cleanup Description: Chase error API changes Removed H5F_addr_pack() routine, which is no longer necessary. Platforms tested: h5committested

* [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).

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