Call fdatasync/fsync after writing out non-meta pages This avoids a case where writes can be reordered so meta page is written before a page it refers to, potentially causing a corrupt database after a power loss or kernel crash. 2014-03-23 03:45:53 +00:00			`package bolt`

Fix bolt on OpenBSD. OpenBSD does not include a UBC kernel and writes must be synchronized with the msync(2) syscall. In addition, the NoSync field of the DB struct should be ignored on OpenBSD, since unlike other platforms, missing msyncs will result in data corruption. Depends on PR #258. Fixes #257. 2014-09-18 20:15:52 +00:00			`func fdatasync(db *DB) error {`
