Message 146307 - Python tracker (original) (raw)

I see that Sun/Oracle Java trusts MoveFileEx to do atomic renames:

290 // atomic case 291 if (atomicMove) { 292 try { 293 MoveFileEx(sourcePath, targetPath, MOVEFILE_REPLACE_EXISTING); 294 } catch (WindowsException x) { 295 if (x.lastError() == ERROR_NOT_SAME_DEVICE) { 296 throw new AtomicMoveNotSupportedException( 297 source.getPathForExceptionMessage(), 298 target.getPathForExceptionMessage(), 299 x.errorString()); 300 } 301 x.rethrowAsIOException(source, target); 302 } 303 return; 304 }
