* [svn-r12649] Description:Quincey Koziol2006-09-051-2/+2
| | | | | | | | | | | | Add a CRC algorithm to the library, initially for "small" (<256 byte) metadata blocks. Update checksum tests to verify it's working correctly. Tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) (Will be testing on more platforms after checkin)
* [svn-r12607] Description:Quincey Koziol2006-08-221-67/+2
| | | | | | | | | | | Tweak the library's new faster fletcher32 algorithm to always produce the same checksum as the previous fletcher32 code in the fletcher32 I/O pipeline filter and switch the filter to use the library's version of the algorithm. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) Too minor to require h5committest
* [svn-r12600] Description:Quincey Koziol2006-08-211-4/+2
| | | | | | | | | | | Clean up code a bit by reformatting and using portable macros for direct C library calls. Tested On: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-25/+25
| | | | | | | | | | | | | | | | | | | | 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

* [svn-r11054] Purpose: Bug fix.Raymond Lu2005-07-081-1/+24
| | | | | | | | | | | | | | | | | Description: There was a bug in the calculating code of the Fletcher32 checksum in the library before v1.6.3. The checksum value wasn't consistent between big-endian and little-endian systems. This bug was fixed in Release 1.6.3. However, after fixing the bug, the checksum value is no longer the same as before on little-endian system. Solution: Made the library compare both the correct checksum and incorrect checksum generated from v1.6.2 or before. This makes the library be backward compatible but not forward compatible. Platforms tested: h5committest and fuss. Misc. update: Documented the forward incompatibility problem in the Known Problem section in RELEASE.txt
* [svn-r9857] Purpose: MaintenanceElena Pourmal2005-01-221-3/+0
| | | | | | | | | | | | | | Description: Removed PABLO from the source Solution: Platforms tested: arabica with 64-bit, copper with parallel, heping with GNU C and C++ and PGI fortran (but I disabled hl, there is some weird problem only on heping: F9XMODFLAG is not propagated to the Makefile files Misc. update:
* [svn-r8781] James Laird2004-07-011-0/+3
| | | | | | | | | | | | | | | | Purpose: HDF5 now supports SZIP with no encoder. Description: SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled. Solution: Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC. Platforms tested: Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++) Misc. update:
* [svn-r8731] Purpose:Quincey Koziol2004-06-231-4/+0
| | | | | | | | | | | | | | | 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-r8251] Purpose:Pedro Vicente Nunes2004-03-111-11/+7
| | | | | | | | | | | | | | | | | | | | bug fix Description: the fletcher filter used a temporary 2 byte word buffer to compute the checksum. this is non portable between big-endian/little endian. Solution: replaced with a buffer of 1 byte type Platforms tested: linux solaris solaris 64 bit AIX windows Misc. update:
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-1/+1
| | | | | | | | | | | | | | | | | | | 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-r7384] Purpose:Quincey Koziol2003-08-191-1/+2
| | | | | | | | | | | Code cleanup Description: More linting... Platforms tested: FreeBSD 4.8 (sleipnir) too minor to need h5committest
* [svn-r7237] Purpose:Quincey Koziol2003-07-171-1/+4
| | | | | | | | | | | Code cleanup Description: Move PABLO_MASK above including headers. Platforms tested: FreeBSD 4.8 (sleipnir) too minor for h5committest
* [svn-r7236] Purpose:Quincey Koziol2003-07-161-9/+9
| | | | | | | | | | | Code cleanup Description: Clean up more warnings from lint. Platforms tested: FreeBSD 4.8 (sleipnir) too minor for h5committest
* [svn-r6731] Raymond Lu2003-04-221-2/+17
| | | | | | | | | Purpose: handling special case Description: This fletcher32 didn't handle Cray's special data type sizes. Platforms tested: h5committested. Cray
* [svn-r6611] Purpose:Quincey Koziol2003-04-091-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code cleanup/new features Description: Switch over to a new style for registering filters with the library - instead passing in an ID, a string and a callback function to H5Zregister, the client should pass in a single pointer to a H5Z_claass_t struct which contains the ID, the description string and all the function callbacks as fields. Added support for a new "can apply" callback for each filter, which is called when a dataset is created to check whether the parameters for that filter apply correctly to the combination of the datatype and the chunk size (i.e. dataspace) for the dataset. Added support for a new "set local" callback for each filter, which is called when a dataset is created (after the "can apply" filter callback) and sets filter parameters that are specific to that particular dataset. Switched the filters we ship over to use the new H5Z_class_t struct for their internal registrations and also added "set local" callbacks to the szip and shuffle filters and a "can apply" callback to the szip filter. Lots of other code cleanups, etc. also Solution: Platforms tested: FreeBSD 4.8 (sleipnir) w/szip Linux 2.4 (sleipnir) w/szip Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/szip, FORTRAN & parallel Misc. update:
* [svn-r6578] Purpose:Quincey Koziol2003-04-031-31/+33
| | | | | | | | | | | | | | | | Code cleanup Description: Added lots of comments to existing filters, so they are easier to understand and use as examples for future filters. Cleaned up various bits of code, etc. Solution: Platforms tested: FreeBSD 4.8 (sleipnir) IRIX64 6.5 (modi4) w/parallel Misc. update:
* [svn-r6546] Purpose:Bill Wendling2003-03-311-3/+14
| | | | | | | | | | | | Update Description: Updated copyright statement in files which hadn't been updated yet. Platforms tested: Linux (Only comment change) Misc. update:
* [svn-r6411] Purpose:Quincey Koziol2003-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.
