[jira] [Resolved] (OAK-1409) After crash, segment persistence is
broken with failures in java.nio classes
[ https://issues.apache.org/jira/browse/OAK-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jukka Zitting resolved OAK-1409.
--------------------------------
Resolution: Fixed
Fix Version/s: 0.18
Fixed in revision 1569770.
The crash had stopped the TarMK at the middle of writing a new segment to disk, and after restart it would assume that the partially written segment already exists, which caused this problem.
The fix detects such partial writes, and truncates the tar file to that point. This should not be a problem, as the journal only gets updated once all pending segments have been flushed to disk and thus the journal should never point to such partially written segments.

> For some unknown reasons my laptop crashed and with it our Oak-based application. After starting it again, the persistence is broken, and nothing works. My OS and file system looks fine (Operating system: OSX Mavericks, rebooted by itself while it was closed, only noticeable through a "your system was restarted" dialog).
> There are java.nio DirectByteBuffer, ByteBuffer and Buffer exceptions (null argument, index out of bounds, and bufferoverflow) see below.
