[fabbione/kronosnet] 868eb7: [handle] remove knet handle tracker
by GitHub 30 Aug '17

Branch: refs/heads/dlopen Home: https://github.com/fabbione/kronosnet Commit: 868eb7816288259f66724f2a9938cb91fdaf5953 https://github.com/fabbione/kronosnet/commit/868eb7816288259f66724f2a9938cb… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2017-08-30 (Wed, 30 Aug 2017) Changed paths: M libknet/handle.c M libknet/internals.h Log Message: ----------- [handle] remove knet handle tracker reload of shlib should be done on a per handle base to avoid complex global functions. For example, if you application is using 2 knet_h and you need to reload libbz2, then switch both knet_h to use another compression method (or none) and switch back to libbz2. Similar can be done with nss/openssl once openssl support is added. A global function to reload all library would a very complex error reporting mechanism and could leave some handles improperly configured. The application would have a better understanding of the needs at any given time. Signed-off-by: Fabio M. Di Nitto <fdinitto(a)redhat.com>
