543d7e9923 Plugging-in the ISA-L backend... Still needs more documentation and a little clean-up, but the tests are passing... 2014-09-29 14:01:56 -07:00
Eric Lambert
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
Eric Lambert
3a108f751c liberasurecode_backend_lookup_id now returns EC_BACKENDS_MAX, as 
opposed to -1, when it can not locate the specified backend (-1
was a non-sensical return value since the function signature
called for a type of ec_backend_id_t). NOTE: with this change we
now successfully build and tests pass on OS X with clang.

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

512353f8be Compile in pedantic mode and fail compilation on warnings. Also cleanup all existing warnings. 2014-09-10 17:13:45 -07:00
Eric Lambert
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.

Eric Lambert
81c47389ba Added more tests (most of which test that the "public" functions 
perform some argument validity checks). Also fixed some bugs exposed by
these new tests. NOTE: liberasurecode_test now *requires* that the null
provider be loadable by the test (meaning is on LD_LIBRARY_PATH).

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.

Updated the backend instance register/unregister methods with lock
 2014-08-16 17:10:26 -07:00
Mark Storer
9c6ba636ec Updated the backend instance register/unregister methods with lock 
status checking.  This shouldn't be an issue, but technically, lock
requests can fail and so should check the return calls out of good
practice.

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).

cc765ef92a Fixed bug where when decoding with a missing data fragment, fragment header 
reconstruction could occurr against the wrong fragment.

009aa4e80b In the erasurecode_preprocessing.c routines for decode/reconstruct, clearly 
distinguish between the fragment and the data/parity buffers, ie
maintain data, parity pointer arrays separate from the fragment
pointers.
