2012-10-16don't do a pending save if slave is syncing.Robin Gareus
13:00 < rgareus> When a slave does initial sync, it sets speed=0, pos=XXX (required by session_process.cc state-machine to init) 13:01 < rgareus> This triggers a locate(roll=false) which in turn triggers a realtime_stop() which in turn triggers a non_realtime_stop(). [..] 13:06 < rgareus> las: the problem I have with non_realtime_stop() is that it does save a pending state IFF get_record_enabled() is true. 13:06 < rgareus> The save can take ages (seconds), which will void the initial sync of the slave. 13:07 < rgareus> The slave enters a live-lock: sync, save, re-sync, save... 13:07 < las> rgareus: understood 13:07 < rgareus> las: I propose to workaround this: only save pending state if there is no slave or the slave is not locked. 13:07 < las> rgareus: another reason why recording + slave == bad idea :( 13:07 < las> rgareus: but yes, that sounds fine to me 13:07 < rgareus> AFICT this is not harmful. It only affects pre-record settings. 13:07 < rgareus> 'did_record' is used to save a full state after each recording. git-svn-id: svn://localhost/ardour2/branches/3.0@13288 d708f5d6-7413-0410-9779-e7cbd77b26cf
