| | | | | | | | | | | Update datasets and the layout, attributes and fill-value object header messages to use the latest version of the file format flag. Tested on: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping)
* [svn-r12680] Description:Quincey Koziol2006-09-251-24/+45
| | | | | | | | | Review, revise & checkin in Peter's latest round of object copy changes, which add basic support for datasets & attributes with reference datatypes. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-021-2/+2
| | | | | | | | | | | | | | Users can create external links using H5L_create_external(). These links point to an object in another HDF5 file. Users can alter the behavior of external links or create new kinds of links by registering callbacks using the H5L interface. Added tests, tools support, etc. Also a number of other, minor changes have been made (some restructuring of the H5L interface, for instance). Additional documentation and examples are forthcoming.

| | | | | | | | | | | | | New feature Description: Check in Peter's code to add support for "shallow copy", "create intermediate groups", "no attributes" and "expand soft links" support. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) w/ & w/o group-revision enabled h5committest
* [svn-r12189] Purpose:Quincey Koziol2006-04-011-4/+4
| | | | | | | | | | | | | | New/expanded features Description: Check in Peter's changed for the object copy code: - Allow/fix copying datasets using named variable-length datatypes - Start adding framework for property list to control how object copying occurs. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

| | | | | | | | | | | | | | | | Bug fix & new feature Description: Support variable-length datatypes in compact data storage and chunked data storage, along with attributes. Bug fix on the H5T_vlen_set_loc to allow for changing the file on a variable-length datatype on disk. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Can't h5committest right now, due to missing cache files.
* [svn-r11850] Purpose:James Laird2006-01-021-19/+57
| | | | | | | | | | | | | | Feature Description: Added character encoding and attribute creation property lists. Solution: Attributes' character encoding is set via the ACPL. The default is ASCII, with UTF-8 being the other option currently. Platforms tested: heping, mir, sleipnir, copper
* [svn-r11758] Purpose:Quincey Koziol2005-12-041-14/+15
| | | | | | | | | | | | | New feature Description: Add in a combination of Peter's & my code to support copying variable-length data from one file to another, although currently only supported with contiguous data storage. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11712] Purpose:Quincey Koziol2005-11-151-23/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)
* [svn-r11686] Purpose:Quincey Koziol2005-11-071-7/+94
| | | | | | | | | | | | | | | | | | | New feature Description: Add in baseline "object copy" code from Peter [in the form of a new API routine: H5Gcopy()]. There's still some work to do (like handling variable- length datatypes and possibly support for references) and it hasn't been tested on mounted files yet, but the core functionality is there and working correctly. I've also got a set of patches to update the 1.6 branch with tweaks to keep the branches mostly in sync, but Elena will kill me if I import them before the 1.6.5 release is out... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committested
* [svn-r11384] Purpose:Quincey Koziol2005-09-121-5/+6
| | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Merge back changes from "compact group" work that improve the infrastructure of the library and may impact others. In this round of merging, that includes: - Move datatype allocation into single internal routine, instead of duplicated code that was spread out in a dozen or so places. - Clean up guts of object header routines (H5O_*) to allow for some of the fancieroperations that need to be performed on groups, along with some general improvements. - Added a new error code - Some minor cleanups in other code.... Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Mac OS X

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. 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

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

* [svn-r9559] Purpose:Quincey Koziol2004-11-221-1/+4
| | | | | | | | | | | | | Code optimization Description: Switch a few more malloc/free pairs over to using internal free list code, to avoid abusing system memory allocator as badly. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9556] Purpose:Quincey Koziol2004-11-221-5/+5
| | | | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Improve ADF/CGNS benchmark by reducing the number of internal attribute copies made during creations, opens and writes. Added new H5O_iterate() routine for iterating through messages of a certain type in the object header (attributes are the only message currently that can have multiple instances in the object header). Cross-pollinated various minor code cleanups to reduce diffs between branches. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9552] Purpose:Quincey Koziol2004-11-191-8/+30
| | | | | | | | | | | | | | | | | Code optimization Description: Avoid making as many copies of attribute information. Also, be smarter about which properties we've seen before when copying and closing property lists. Fix memory leak of attribute data structures. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9537] Purpose:Quincey Koziol2004-11-171-17/+8
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup & optimizations Description: Clean up some of the code in attributes to avoid allocating memory and performing type conversions when the conversion is a noop. Avoid memory allocations of attribute data structures by switching to use library's free list memory allocator routines. Avoid memory allocations of object header continuation data structures by switching to use library's free list memory allocator routines. Rearrange threaded, balanced binary tree macros slightly to avoid some overhead. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) Too minor to require h5committest
* [svn-r9433] Purpose:Quincey Koziol2004-10-191-1/+4
| | | | | | | | | | | | | | | | Bug fix Description: Fix core dump when flushing a file with a newly created attribute which hasn't had a value written to it still open. Solution: Write the attribute fill value when appropriate. Platforms tested: FreeBSd 4.10 (sleipnir) Linux 2.4 (verbena) Solaris 2.7 (arabica)
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-13/+8
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r8673] Purpose:Quincey Koziol2004-06-131-1/+1
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8590] Purpose:Quincey Koziol2004-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage.

* [svn-r8376] Purpose:Quincey Koziol2004-04-171-40/+11
| | | | | | | | | | | | | | | | | Code cleanup Description: Update null dataspace changes to try to write older version of dataspace information whenever possible. Refactor common code to only one location. Allow I/O operations to succeed on null dataspaces. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r8330] Purpose: Last step of check-in for Null dataspaceRaymond Lu2004-04-081-28/+55
| | | | | | | | | | | Description: Mainly are header message changes for dataspace. In last round of check-in, a new header message for dataspace to created, which is not a good way. Now, there will be no new message for dataspace, but just add the type of dataspace in the message while increment its version number. Backward compatibility is addressed. The attribute design is modified accordingly. Platforms tested: h5committest
* [svn-r7950] Purpose:Quincey Koziol2003-12-131-1/+9
| | | | | | | | | | | | | | | | Bug fix Description: Attributes which were created with scalar dataspaces were reporting their dataspace as a simple dataspace when queried later. Solution: Fix the dataspace handling code when reading in the attribute message from the file to set the extent type correctly. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7538] Purpose:Quincey Koziol2003-10-051-42/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes and code cleanup Description: Lots of changes here: - Fixed bug #691 - when shared datatypes are used in attributes they are incorrectly copied into the attribute instead of referring the the named datatype in the file. This required bumping the version of the attribute message. The new version of the attribute message is only written out when a shared datatype is used in the attribute. [Also, this format change made the size of the attribute smaller.] - Added information to attribute debugging routine so that shared datatypes are displayed correctly with the h5debug tool. - Refactored the H5O* routines to extract code that was common to several routines into subroutines to call. - Added 'link' method for H5O message sub-classes, which increments the link count on shared objects when a message is created which shares them. - Corrected [unreported] bug where the link count was not being decremented on the shared object when a object header message with a reference to that object was deleted from the file. - Reduced size of shared message from 49 bytes (which was incorrect anyway and should have been 48 bytes) to 10 bytes, which required bumping the version of "shared" messages. - Refactored some of the shared datatype routines to allow for easier queries of "committedness" internally to the library and also added routine to easily increment/decrement the reference count of a shared datatype.

* [svn-r6837] Purpose:Quincey Koziol2003-05-081-8/+8
| | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | New feature, sorta Description: Track changes to various internal APIs 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-r6411] Purpose:Quincey Koziol2003-02-171-18/+19
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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-r5842] Purpose:Quincey Koziol2002-08-081-26/+39
| | | | | | | | | | | | | | | | 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-r5839] Purpose:Quincey Koziol2002-07-311-0/+3
| | | | | | | | | | | | | | | Code cleanup Description: Move operations on each type of selection into the source code file for each selection type (all->H5Sall.c, hyperslab->H5Shyper.c, etc.) Remove central H5S_select_<foo> operations, instead calling the operations through function pointers in each selection (a much more object-oriented approach). Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-6/+6
| | | | | | | | | | | | | | | | 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-r4643] Purpose:Quincey Koziol2001-11-271-26/+14
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-8/+8
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3677] Purpose:Albert Cheng2001-03-201-4/+0
| | | | | | | | | | | | | Bug fix (sort of) Description: The RCSID string in H5public.h was causing the C++ code problem as it was included multiple times and C++ did not like multiple definitions of the same static variable. Solution: Since we don't really make use of the RCSID strings as we have not installed it in all source files, we decided to remove it. Platforms tested: eirene (linux), modi4 (IRIX64-64) both serial and parallel modes.
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-1/+3
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)
* [svn-r2073] Added free-list code to the library and took out the older ↵Quincey Koziol2000-04-041-2/+10

I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes. Changed an error message. ./config/BlankForm ./config/dec-flags ./config/gnu-flags ./config/hpux10.20 ./config/hpux9.03 ./config/irix5.x ./config/irix6.x ./config/solaris2.x ./config/unicosmk Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the configuration since they're no longer applicable. The default file driver is always the sec2 driver and it always optimizes calls to lseek() or lseek64(). ./config/depend.in C preprocessor errors generated during automatic dependency building are sent to /dev/null to prevent them from appearing twice in the make output. ./src/H5AC.c ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oshared.c ./src/H5T.c ./src/H5detect.c ./test/ohdr.c Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent with the `haddr_t' datatype which is now a public type. ./src/H5D.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Tconv.c ./test/cmpd_dset.c ./test/dsets.c ./test/overhead.c ./test/tselect.c ./test/tvltypes.c The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER because the properties apply to all types of I/O operations, not just datasets. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5R.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/big.c ./test/h5test.c ./test/istore.c ./testpar/t_dset.c ./testpar/t_file.c ./tools/h5debug.c ./tools/h5ls.c Modified to work with the virtual file layer by calling H5FD_* functions instead of H5F_low_* functions and by passing file access and data transfer properties by object ID instead of pointer. Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.

This is one of the preliminary changes needed for the Virtual File Layer stuff. ./src/H5Fprivate.h [1.3] ./src/H5Flow.c [1.3] Some address functions were rewritten as macros.

Thanks to Quincey, the comment no longer applied. ./src/H5T.c Relaxed the H5Tpack() a little so it would pack compound data structures that had non-transient atomic members. ./tools/h5ls.c Added a `-g' (or `--group') flag that causes information to be printed about the specified group instead of the group's contents. (sort of like Unix's `ls -d'). The `-g' can be used in combination with `-r' to print information about the group and its contents.
