[Bug 1127521] Re: shotwell crashes after a while of Updating library...
Remember, Shotwell doesn't do the file locking, SQLite does. I don't know how it handles the problem if file locking fails, or even if the file sharing stack is reporting an error. More importantly, Shotwell is not designed to work this way. Shotwell keeps a lot of the database in memory for speed reasons, so if the database was cleanly modified by another user, Shotwell would not know and could even later overwrite those changes. File locking is not the only issue; database incoherence is as much a problem here as actual file corruption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1127521 Title: shotwell crashes after a while of Updating library...

Weird... During the NTFS-over-NFS segfault there was only single instance of shotwell running.

I don't mean to suggest that's what caused your problem in particular, only that the reason Shotwell doesn't support sharing the database among multiple users can lead to a lot of problems, both data corruption and database incoherence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1127521 Title: shotwell crashes after a while of Updating library...

[Bug 1127521] Re: shotwell crashes after a while of Updating library...
It would be nice if shotwell check whether underlying filesystem supports necessary locking semantics and show informative error message if it is not the case. Doesn't explicit file lock operation returns error if file locking failed?? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1127521 Title: shotwell crashes after a while of Updating library...

This bug is about inability of shotwell to have its database on a network drive (NTFS-over-NFS).

[Bug 1127521] Re: shotwell crashes after a while of Updating library...
With db a local ext4 filesystem (shotwell -d /var/tmp/shotwell/) shotwell worked perfectly. Downside of the approach is that the db is not accessible by other computers on the network. I really want the db to sit on the NTFS-over-NFS partition, so other members of the family can manage the photos repository (including db manipulation) with no files permissions headache. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1127521 Title: shotwell crashes after a while of Updating library...

This is not a recommended use case, see http://redmine.yorba.org/projects/shotwell/wiki/ShotwellFAQ#Can-I-access-a -Shotwell-library-across-a-network-possibly-from-multiple-machines and http://www.sqlite.org/whentouse.html.

[Bug 1127521] Re: shotwell crashes after a while of Updating library...
The DB area have been emptied before, so the DB have been created from scratch. There is no problems with disk space, dmesg shows only the segfault message (BTW, segfault is not the best way to exit, even when an error occured). The filesystem is NTFS-over-NFS, so could be it lacks locking semantics required by sqlite. I will check shotwell on a regular ext4 filesystem tonight. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1127521 Title: shotwell crashes after a while of Updating library...

That's a fatal error being reported by SQLite, the embedded database Shotwell uses to store its library information. SQLite's result code 10 (from this page: http://www.sqlite.org/c3ref/c_abort.html) #define SQLITE_IOERR 10 /* Some kind of disk I/O error occurred */ That plus dmesg tells me you have a disk problem.
