Hi Andy, The version check is done properly for the XrdClProxyPlugin: When the plugin version doesn't match it is rejected: > [simonm@idefix XrdCl]$ strings -a $XRD_PLUGIN | grep "@V" > @V:XrdClGetPlugIn v3.9.9 > [simonm@idefix XrdCl]$ strings -a libXrdCl.so | grep "@V" > @V:client v4.9.9 > [simonm@idefix XrdCl]$ ./xrdcp -f -d 1 root://esvm000//tmp/file1.dat /tmp/dump > [2017-03-28 15:14:19.234129 +0200][Debug ][Utility ] Unable to process user config file: [ERROR] OS Error: No such file or directory > [2017-03-28 15:14:19.234302 +0200][Info ][Utility ] Env: Importing from shell XRD_PLUGIN=/home/simonm/test/xrootd-3.9.9/build/src/libXrdClProxyPlugin.so as PlugIn > [2017-03-28 15:14:19.234335 +0200][Debug ][PlugInMgr ] Initializing plug-in manager... > [2017-03-28 15:14:19.234387 +0200][Debug ][PlugInMgr ] Loading default plug-in from /home/simonm/test/xrootd-3.9.9/build/src/libXrdClProxyPlugin.so... > [2017-03-28 15:14:19.234611 +0200][Debug ][PlugInMgr ] Error while loading /home/simonm/test/xrootd-3.9.9/build/src/libXrdClProxyPlugin.so: Unable to load client plugin /home/simonm/test/xrootd-3.9.9/build/src/libXrdClProxyPlugin.so > [2017-03-28 15:14:19.234625 +0200][Debug ][PlugInMgr ] Failed to load default plug-in from /home/simonm/test/xrootd-3.9.9/build/src/libXrdClProxyPlugin.so > [3.015kB/3.015kB][100%][==================================================][3.015kB/s] If the plugin version does match it is loaded: > [simonm@idefix XrdCl]$ strings -a $XRD_PLUGIN | grep "@V" > @V:XrdClGetPlugIn v4.9.9 > [simonm@idefix XrdCl]$ strings -a libXrdCl.so | grep "@V" > @V:client v4.9.9 > [simonm@idefix XrdCl]$ ./xrdcp -f -d 1 root://esvm000//tmp/file1.dat /tmp/dump > [2017-03-28 15:15:05.885847 +0200][Debug ][Utility ] Unable to process user config file: [ERROR] OS Error: No such file or directory > [2017-03-28 15:15:05.885951 +0200][Info ][Utility ] Env: Importing from shell XRD_PLUGIN=/home/simonm/test/xrootd-4.9.9/build/src/libXrdClProxyPlugin.so as PlugIn > [2017-03-28 15:15:05.885971 +0200][Debug ][PlugInMgr ] Initializing plug-in manager... > [2017-03-28 15:15:05.885992 +0200][Debug ][PlugInMgr ] Loading default plug-in from /home/simonm/test/xrootd-4.9.9/build/src/libXrdClProxyPlugin.so... > [3.015kB/3.015kB][100%][==================================================][3.015kB/s] To be honest the XrdClProxyPlugin is the first plugin that will be included with xrootd core, so there is no convention yet. Hence, it's up to you whether we should follow the "-4" naming convention, or not ;-) Cheers, Michal -- You are receiving this because you are subscribed to this thread.
