Proper way to detect real rename #104
Description
Note: I don't necessarily need this in a cross-platform way, Linux-only would be fine. But cross-platform is always nice.
I'm making a recursive watcher for a medium-sized folder structure (~50000 files organized in a tree). I'd like to properly detect renames within the structure, so I can update some fields in a database instead of a delete/insert combo.
As of now, the only decent "solution" I've come up with is to walk the entire folder structure and save all os.FileInfo structs in a slice. Then, when a CREATE event comes (because the RENAME event doesn't mention the new name, it seems a bit useless). I check whether I already knew the file with os.SameFile, going over all saved os.FileInfo's. This sounds very heavyweight and I'd like to avoid it if at all possible.
Am I going about this the wrong way? Did I not look hard enough on Google and the mailing list (go-nuts)? (if that's the case, I apologize, I did try searching).
