Locking edited file

[davitof]

Hello,

I accidentally opened the same book twice in the editor. That is, I opened it once and edited and e-book, did something else, missed the fact the editor was already open and opened it once again and did some other edits. Then I saved one of the versions (I don't know which, it doesn't matter any more), and closed the editor window. Then I saw the second editor window and tried to close it, and the editor asked me if I wanted to save, and that's when I realized what was happening. Which of course meant I had to merge my edits.

All this could be avoided if Calibre used some locking mechanism. For example, the editor could create a temporary file upon opening an e-book, refuse to reopen or at least display a warning if it finds this file, and delete the file when the editor window is closed.

Is there any chance that such a mechanism will be implemented in the future ?

No, being able to edit the same book in multiple windows is a feature, not a bug. It allows you, for example, to reference a different part of the book in one window while eidting it in the second.
