483764209c Initial commit of an exanded error status struct. This commit is 
largely brainstorming.  The error messages, the order, the value,
everything is there to start the discussion.

be8dcbcc27 Char * backend names are no longer supported. They have been replaced with elements of the ec_backend_id_t enum. 2014-09-29 13:24:50 -07:00

06bb20ca1c crc32 checksum now supported (prior to this commit checksum values were 
not being placed into the fragment header).

6bbcfde657 added argument validation logic and tests for 
liberasure_get_fragment_metadata and
liberasurecode_verify_stripe_metadata. In the process removed the
liberasure descriptor from the liberasure_get_fragment_metadata
function's signature as it was not being used in the function's
implementation.

c9af505400 Backend changes needed to honor "excluded fragments". 2014-08-21 13:05:59 -07:00
Kevin Greenan
d251ed8f98 API change for liberasurecode_fragments_needed 
Still needed:

1.) RS and XOR backends need to honor the 'exclude' argument.
2.) Need to add tests.

8af4f83e86 - Cleaned up the documentation in erasurecode.h to ensure that it 
follows a common format and that it accurately reflects the code.
- Cleaned up liberasurecode_instance_destroy to ensure that the return
  code is correct and that it is not trying to free data that has
  not been removed from the open instances.
- Updated the tests to assert that the liberasurecode_instance_destroy
  method is return correctly.

4cfd3f535b Updated liberasurecode_supported_checksum_types to accept a pointer 
argument that holds the length of the list returned (i.e. the number of
supported checksum types).

e39aaa3dd9 Created helper function to iterate over a set of data/parity fragments 
and create an array of pointers to the data segments for each fragment
(this array can then be passed to backend decode functions).
