We're dealing with a complex system of the user, the application, the operating system, the hardware and the electrical power. Failure can happen at any point. We manage to escape application crashes from setting your house on fire. That wasn't always so in the history of computing. Failures are generally limited, or at least engineers try their best. If power goes out during a save operation, three failures can generally occur (and I'm speaking generally, not just about OpenOffice): 1) The user loses the data that was in memory but not yet written to disk. 2) The user loses both the data that was in memory (current state of the document) as well as the previous state of the document (the version already on disk) 3) The user loses both versions of the document as well as corrupts their file system causing other, totally unrelated files to be lost. Anyone remember #3, how things were 20 years ago? Hopefully OS vendors have generally solved that problem. But I think we know how to solve, or at least reduce problem #2. The trick is to reduce the "window of vulnerability" for total loss by saving initially to a temporary file, and only after the file is completely saved then rename it. Since an OS-level rename operation is lighting fast, you reduce your risk. And if power does go out during the rename operation, modern OS's will know enough to rollback the file names so you still have your temporary file in place. Then the app can check for any temporary files when it loads and offer to restore them. So it is possible to do something reasonable here. Of course, in case 1) above, auto backup is your friend. -Rob > Hagar > > > >> Hi, >> first, thank you for all the products of open office. >> i want to tell you that when the file(.odt) is saving and if the computer >> shute down(simultanesly), the file became empty when the computer is >> restarted. >> thank you again. >> > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
