From 35fdb730b733cec49f5c7cb4807eabed08631712 Mon Sep 17 00:00:00 2001 From: "Kaleb S. KEITHLEY" Date: Wed, 5 Nov 2014 13:59:37 -0500 Subject: api: versioned symbols in libgfapi.so for compatibility Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0 Some nits uncovered: + there are a couple functions declared that do not have an associated definition, e.g. glfs_truncate(), glfs_caller_specific_init() + there are five private/internal functions used by heal/src/glfsheal and the gfapi master xlator (glfs-master.c): glfs_loc_touchup(), glfs_active_subvol(), and glfs_subvol_done(), glfs_init_done(), glfs_resolve_at(); which are not declared in glfs.h; + for this initial pass at versioned symbols, we use the earliest version of all public symbols, i.e. those for which there are declarations in glfs.h or glfs-handles.h. Further investigation as we do backports to 3.6, 3.4, and 3.4 will be required to determine if older implementations need to be preserved (forward ported) and their associated alias(es) and symbol version(s) defined. FWIW, we should consider linking all of our libraries with a map, it'll result in a cleaner ABI. Perhaps something for an intern to do or a Google Summer of Code project.
