* [svn-r12768] Description:Quincey Koziol2006-10-161-5/+5
| | | | | | | | | | Add 'initval' parameter to "lookup3" checksum routine (and implicitly to the metadata checksum routine), to allow chaining several checksums together easily (which isn't used by these modules, but will be used in my next checkin) Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12661] Description:Quincey Koziol2006-09-121-10/+182
| | | | | | | | | | | Add 'loookup3' checksum routine and switch to using it for metadata checksums - it's just as "strong" as the CRC32 and about 40% faster in general (with some compiler optimizations, it's nearly as fast as the fletcher-32 algorithm). Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12649] Description:Quincey Koziol2006-09-051-9/+124
| | | | | | | | | | | | 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-r12612] Description:Quincey Koziol2006-08-221-0/+35
| | | | | | | | | | Provide more abstract internal routine for computing checksums on metadata in a file. This will allow a unified policy on which algorithm to choose and under what criteria (length probably) to be more easily maintained. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12607] Description:Quincey Koziol2006-08-221-2/+7
| | | | | | | | | | | 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-r12606] Description:Quincey Koziol2006-08-221-19/+7
| | | | | | | | | | | Switch to somewhat less high performance checksum implementation that doesn't run into problems for mis-aligned buffers in memory. Tested On: FreeBSD/32 4.11(sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12605] Description:Quincey Koziol2006-08-211-0/+145
Break out a bunch of the misc. routines that were in src/H5.c into more specific modules. Add optimized fletcher32 checksum routine, for checksumming metadata as well as raw data. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) Will test further after checkin...
