[Gluster-devel] gfapi: Changed API signatures in release-6

[Shyam Ranganathan]

Hi,

A few GFAPI signatures have changed in release-6 and the list can be
seen here [1]. The change is to adapt to a more elaborate stat structure
than what POSIX provides and details around the same can be seen here [2].

If you have an application that compiles against gfapi, then it needs to
adapt to the new APIs in case you are buildnig against master or against
release-6.

Existing compiled applications will continue to work as the older
versions of the symbol are present and have not changed their ABI.

Further, if your build environment still depends on a version less than
release-6 or master, the builds and functionality remains the same (IOW,
there is not immediate need to adapt to the new APIs).

Components that I know integrate to gfapi and hence may need to change are,
- Samba Gluster plugin
- NFS Ganesha FSAL for Gluster
- TCMU-Gluster integration
- QEMU Gluster integration
- Other language API bindings
  - go
  - python
  - <insert other>
- Anything else?

Request respective maintainers or members working with these integration
to post required patches to the respective projects.

Thanks,
Shyam
