Collation: Create shared library for engines to use

Details

    Description

      In order for handler engines, e.g. columnstore, to collate correctly and identically to innodb, we need access to the same collation code as the server. currently this code is included in server as object files, making it difficult for other projects to include it. This JIRA is a request to include the code in a shared library accessible by both the server and engines.

      Note that having it as service is not enough, because some engines (e.g. columnstore) has separately running binaries that needs to collate strings too.

            Code bloat is not an issue, those libraries are rather tiny. David.Hall, should be keep the issue open, or can we close this, if static linking works for you?

            If the libs are ready, this can be closed. I may need to bother you if I have problems getting things to link. Probably won't have a problem, but you never know.

            The libs are "strings", they are there, and always been, during the server build. The interdependency between strings and mysys is mentioned by serg, so one might need to link with mysys as well, and also with dbug.

            Supporting collation/charset code is in mysys — loading, comparing, compiling, etc. Actual collations/charsets are in string.

            I'm closing it for now. Hopefully there is no problems with proposed solution (static libs)
