Subject: [SPDK] SPDK ABI Improvements

Hello All,

We are taking several steps towards solidifying the ABI strategy for SPDK. These include the following:


  1.  Creating an ABI major/minor versioning scheme for all shared libraries. When a new symbol is added to a library, the shared object minor version will be incremented to show that the library is still backwards compatible. When a symbol is removed or changed, the ABI major version will be updated to indicate that the library is no longer backwards compatible. This versioning scheme will be enforced by the following new test in the SPDK CI: https://review.spdk.io/gerrit/c/spdk/spdk/+/1068.
  2.  Incrementing the shared object version of each library independently.
  3.  Creating individual map files for each shared library.

As we create individual map files for the libraries, ABIs are likely to change, so please keep an eye out for changes in the major/minor version of SPDK libraries as you continue to link your applications to them.

Thank you,

Seth Howell
