Extended format management in eblob, stats and tests improvements

SaveTheRbtz commented 11 years ago

Replaced general purpose BLOB_DISK_CTL_USR1 flag with special BLOB_DISK_CTL_EXTHDR which changes eblob behavior in various ways so that metadata management in elliptics can be implemented efficiently;
Fixed writev() behaviour for iovcnt > 1;
Tests improvements: added writev() tests, improved append and three stage write;
Proper cleanup of bases which are removed due to absence of entries;
Many statistics fixes;
Comment and logging improvements;
Various static analyzer/pedantic fixes.

@zbr: New release and major version bump are needed.

bioothod commented 11 years ago

Does this release break abi/api, so that new major version is required? Or 0.20.1 is ok?

SaveTheRbtz commented 11 years ago

I think it should be 0.21.0 because meaning of (1<<6) flag was changed (ABI) along with it's name (API)
