Re: [Gluster-devel] Determining libgfapi/glusterfs version

[Anand Avati]

This looks more like a compile time feature check than runtime. The PKG_CONFIG() api number which had the initial set of QEMU requirements was 3 (i.e, PKG_CONFIG(..,glusterfs-api>=3,..). The new updates for Samba requirements has api number 4. Depending on whether discard support makes it before the next release (and api numbers gets published) or not, glfs_discard() would either be available in 4 or 5. Also, you might also want to add a second AC_CHECK_FUNC macro in configure.ac to be doubly sure.

Hi,

What is the best way to determine if I am running (or linked to) a
particular version of libgfapi/glusterfs ?

This would be a runtime determination, right? We are evolving versions for libgfapi that is independent of the package version.

http://review.gluster.org/#/c/4932/

Requirement: If I want to support the use of glfs_discard() from QEMU,
I should be doing it only if QEMU is linked to a version of libgfapi
that supports glfs_discard().

Maybe a new api glfs_get_version() can be evolved to determine libgfapi capability at runtime?

Vijay
