* [svn-r8731] Purpose:Quincey Koziol2004-06-231-8/+9
| | | | | | | | | | | | | | | 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-r7917] Purpose:Quincey Koziol2003-12-061-6/+6
| | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | 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 Koziol2003-02-101-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r5842] Purpose:Quincey Koziol2002-08-081-89/+62
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-1/+1
| | | | | | | | | | | | | | 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-r5839] Purpose:Quincey Koziol2002-07-311-3/+4
| | | | | | | | | | | | | | | 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 Koziol2002-05-291-5/+5
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | 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)
* [svn-r4756] Purpose:Quincey Koziol2001-12-221-1/+1

* [svn-r4747] Purpose:Quincey Koziol2001-12-201-3/+159
| | | | | | | | | | | | | | Bug Fix. Description: The H5Rget_object_type function could not get the object type for dataset region references. Solution: Added a new function, H5Rget_obj_type, to replace H5Rget_object_type. The new function requires the reference type as an additional parameter, in order to allow queries on different reference types to be performed correctly. Platforms tested: FreeBSD 4.4. (sleipnir)
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-10/+6
| | | | | | | | | | | | | | | | | | | | | | 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)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-11/+11
| | | | | | | | | | | | | | | | | | | | | | 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 Wendling2001-04-051-11/+11
| | | | | | | | | | | | | | | | | | 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-r3252] Purpose:Quincey Koziol2001-01-091-2/+4
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3065] Purpose:Quincey Koziol2000-12-021-30/+15
| | | | | | | | Code cleanup Description: Remove some warnings... Platforms tested: FreeBSD 4.2 (hawkwind) & IRIX64 6.5 (modi4)
* [svn-r2689] Purpose:Quincey Koziol2000-10-171-0/+4
| | | | | | | | | | | | | | | | | Bug fix. Description: Previously, it has been possible to dereference deleted objects in a file. Obviously, this is incorrect and could cause all sorts of problems if the object being dereferenced had been partially over-written with other information. - This is documented in Bug #493. Solution: Check the link count for objects being dereferenced and don't allow any objects with link counts of zero to be dereferenced. This fixes bug #493. Platforms tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2657] Quincey Koziol2000-10-101-1/+0
| | | | | | | | | | | | Purpose: Parallel Bug Fixes Description: Was out of sync with header file re-arrangements I checked in last night. Solution: Fixed to use new header files, etc. Platforms tested: O2K (modi4)
* [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)

The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver. Removed #warning about not having the stdio driver. Plans are to not implement it since the sec2 driver serves the same purpose and testing didn't show any difference in execution times between the two.

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 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.

* [svn-r1385] Updated H5Rdereference, H5Rget_object_type and H5Rget_region ↵Quincey Koziol1999-06-251-39/+72
| | | | | | | | | | | to accept a location ID (i.e. a file or group ID) as well as the dataset ID. This should allow Dave to get the palettes stored in the file correctly and also enable Bob and/or Bruce's indexing stuff. This change should be folded into the documentation for these three functions for the release. Also, I fixed a number of bugs in the hyperslab and point selection iterators for H5Diterate and they are working correctly now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./doc/html/Datatypes.html ./test/dtypes.c Added documentation and tests for opaque types. ./tools/h5ls.c Added a `-x' or `--hexdump' argument which is not fully implemented (because I want to synchronize h5tools.c first) but which will eventually print raw data in hexadecimal format without any translation from disk. This would be useful for debugging references and VL types. ./tools/h5tools.c Added support for references (not quite finished yet, but compiles -- I wanted to sync up this file before Patrick and I got too far apart...) ./src/H5R.c Checked for error return value from H5R_get_object_type() ./src/H5A.c ./src/H5D.c Changed error return values from NULL to FAIL ./test/Makefile.in ./test/trefer.c Creates trefer1.h5 and trefer2.h5 so that the second test doesn't clobber the first file since the files might be useful for debugging.

The fix works only on systems that have the vsnprintf() function (otherwise a 4kB limit is imposed, which if violated probably dumps core). If vsnprintf() is present then the library dynamically allocates space for the output string. Also made it possible to control how compound data is rendered across multiple lines of output by allowing the caller to specify where optional line-breaks get inserted. The output functions split up the value at one or more optional line-breaks to prevent it from wrapping around the screen. If a datum doesn't fit on the current line but would fit on the next line then it is printed on the next line regardless of whether optional line-breaks would have prevent wrapping around the screen. This makes it easier to find the beginnings of compound data values. This feature is disabled by default but can be enabled by the application. If a datum doesn't fit on the current line and the previous datum also occupied more than one line then we move to the next line before printing. This makes it easier to find the beginnings of compound data values but prevents the output from looking fragmented if there are only a few long values among mostly short values. This feature is disabled by default but can be enabled by the application. The application can control the printf() formats used for all the native data types. The defaults are what the library used to use: %g, %ld, %lu, %d, and %u ./tools/h5ls.c Compound datatype values can now be split across multiple lines of output instead of just wrapping. Also, when lots of compound values are too long they all start at the beginning of a line. This only required about 10 lines of changes in the setup for tools library calls (I didn't modify the h5dump program because it uses its own version of the tools library that forked off long ago). Added code for Win32 which is unable to cast `unsigned long long' to `double'. If the dataset size exceeds (2^63)-1 then the percent utilization is not displayed (this is easily possible with chunked datasets). This is untested yet. ./configure.in ./src/H5config.h.in ./src/H5.c ./src/H5private.h Check for vsnprintf() and provide a simple, stupid definition if it isn't available. The stupid definition just calls vsprintf() and ignores the second argument. This can result in buffer overflows in h5ls and h5dump since vsprintf() is an unsafe function (and anyone can create an hdf5 file that runs an arbitrary command from h5ls and h5dump in that case)! ./config/conclude.in Remove more *.o files for `make clean' ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c Cleaned up a memory leak during H5_term_library() by allowing H5I_clear_group() to skip items that couldn't be freed. This allows the item to remain in the group until we can free it later. ./src/H5F.c The H5F_close_all() function fails if a file cannot be closed.

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.

Also fixed a bug for undefined variable in H5D when H5S debugging is turned on but H5T debugging is turned off. ./config/conclude.in Fixed installation of header files for building in a directory other than the source directory. This fixes a bug where H5config.h wasn't being installed. ./src/H5.c ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c ./src/H5Tprivate.h ./src/H5Z.c ./src/H5detect.c ./src/H5private.h Changed the way the library shuts down again. Now it handles cycles between packages and isn't so sensitive to dependencies between packages. A package might shut down only to be restarted to process a request from some other package being shut down. Loops are detected after 100 iteractions and the shutdown is aborted with a message on standard error. This also makes it a lot easier to debug. ./src/H5A.c Fixed H5A_write() and H5A_read() so they pass a non-null background buffer to the conversion functions. This is necessary when an attribute has a compound data type. ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c Reindented new Win32 stuff. ./src/H5Odtype.c Fixed a bug when enumeration types are used in a compound data type. The byte pointer wasn't incremented after the type information was written. ./tools/h5ls.c Compound data types display their total size because it's not always obvious from looking at the members. Scalar attributes show their space as `scalar' instead of `{}'. The index value is not printed for attributes that have only a few values. Instead the word `Data:' is printed on the first line of attribute data. Named types display their data type only if verbose output was requested.

This is especially useful if you want to concurrently compile with different compilers and/or compile flags, or if the hdf5 source is on read-only media like a CDROM. The changes were surprisingly easy ;-) Here's what you can do now... $ mkdir /tmp/build1 # or something $ cd /tmp/build1 $ /cdrom/hdf5/configure # where ever the source is $ make Paul, you'll have to change the testh5toh4 script similar to the way I changed testh5dump.sh. I started working on it but then gave up because of a number of problems: (1) I had to comment out all the tests that let h5toh4 choose the output file name because it always tried to put the output file in the same directory as the input file, (2) if path names are used during the h4 dump then they interfere with the diff. The test works fine when run in the source directory, but try this instead: $ gunzip <hdf5-1.1.67.tar.gz |tar xf - $ chmod -R ugo-w hdf5-1.1.67 $ mkdir build $ cd build $ ../hdf5-1.1.67/configure $ make check Dan, I didn't modify the pablo/Makefile.in because I have no way to test it. I think all you need to do is add a couple lines before the @COMMENCE@ line and add a couple search directories for header files. Anyway, it seems like almost an exact duplicate of the src/Makefile.in, so it shouldn't be a problem... ./Makefile.in Removes a few more temporary files during make clean and distclean. ./configure.in I fixed the creation of the time-stamp files so that the initial make doesn't have to regenerated all the makefiles (only GNU make users will see any change). ./src/H5R.c Changed a return type from `intn' to `int' for an API function. ./src/H5detect.c Added the volatile qualifier to a couple more variables. ./tools/h5tools.c Fixed a compiler warning about an unused local. ./tools/h5toh4.c Initialized `optind' to 1 because it's zero on my system. It should always be one on a unix system. ./tools/testh5toh4 Redirected "broken pipe" messages to /dev/null so outut is formatted correctly.
