There was a problem hiding this comment.
bytes_allocated is never used, because we don't have block pruning yet. This introduces a compiler warning that can be squelched by simply re-writing the line as follows until block pruning is introduced.
/*size_t bytes_allocated = */BlockFileSeq().Allocate(pos, nAddSize, out_of_space);

This is part of the block logic refactoring and encapsulation work coming from upstream (work started in #2326 and #2328 due the possible blocks db corruption issue).
Needed for two future works: (1) faster block validation using a new cache structure and (2) the future possible custom BIP157 (new sync protocol that supersedes BIP37 for light clients -- pending research needed after finishing v6.0 priorities --)
Essentially, it's encapsulating the sequenced files open/read/write functionalities inside a new
flatfilemodule, and extending the unit test coverage to validate its correct behavior.Adapted the following PRs:
