Fixed random SQLite error code:522, 'not an error'

[PGLongo]

I've fixed an error that can affect some Simulator (mine for example) running unit-test.

2015-10-21 17:10:24.579 xctest[703:8687] CoreData: error: (522) I/O error for database at /Users//Library/Developer/CoreSimulator/Devices/5E7487DC-2883-45F6-8CC1-FB90A2EB73C1/data/Documents/Pokemon.sqlite. SQLite error code:522, 'not an error' fatal error: 'try!' expression unexpectedly raised an error: Error Domain=NSCocoaErrorDomain Code=522 "(null)" UserInfo={NSSQLiteErrorDomain=522, NSUnderlyingException=I/O error for database at /Users//Library/Developer/CoreSimulator/Devices/5E7487DC-2883-45F6-8CC1-FB90A2EB73C1/data/Documents/Pokemon.sqlite. SQLite error code:522, 'not an error', NSFilePath=/Users/*/Library/Developer/CoreSimulator/Devices/5E7487DC-2883-45F6-8CC1-FB90A2EB73C1/data/Documents/Pokemon.sqlite}: file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-700.0.59/src/swift/stdlib/public/core/ErrorType.swift, line 50

Running multiple tests the database seems to be corrupted, maybe caused by sqlite temporary files.

I've improved NSPersistentStore deletion in tearDown.

Thanks

hopefully this will let unit tests stop failing on my build server :dancers:

Same error?

[michaelarmstrong]

mine was test manager service generic error (typical Xcode server error)... its integrating now... will let you know if it passes :D

[michaelarmstrong]
