hopefully this fixed the strange autorecovery related dataloss fdo#42899
also this is a fix for bnc#817477 Disabling the optimisation of copying the library container storage to target storage for the moment ( hopefully after some rework it might make some sense to re-enable this code ) The problem here is there is a tragic flaw in the api implementation. In the implementation the library in-memory model state reflects that the library model has been saved to storage but not the library container storage as you ( or at least I ) would expect but actually any storage. So to illustrate the problem, during autorecovery when the basic library containers are stored to the autorecovery file the library pImplLib->implIsModified() is set to false, any subsequent save attempt will think the library is not modified and will attempt to the librarycontainer storage to the target one. However, in this case the source (library container) storage has never been updated with the changes from memory. Can't we simply only update the 'implIsModified' state only if the library container's own storage and the storage to store to are the same ? Sounds like a good idea, unfortunately this is not possible due to the way that sfx spaghetti code uses temporary storages for even own copies and also because it sets the new root storage for the library container after the library copy happens. ( some stuff in dbaccess appears to depend on this as well ) AFAICT for any document save/saveas etc. operation the librarycontainer's own storage and the storage we save to are *always* different. So for the moment it seems best to *always* write the storage from the in-memory model. Change-Id: Ia24e7a6119558497d901370dbc0986101bde4de9
