Mercurial (and, I guess Git) with Dropbox: any drawbacks?

Question

I have a Mercurial repository for a personal project, and I have been storing the master repository in my Dropbox for a few weeks now (something along this line; and I under

I'd advise against it for the reasons stated above, but more strenuously stated. Both mercurial and git have their own protocols for moving changesets between repositories. These protocols are optimized/built for:

• efficiency
• consistency (never can you pull from a repo in a half-updated state)
• hooks/triggers -- doing things on push/pull including quality (no tabs allowed, etc.) filters

When you just let a directory sync handle the keeping of the .hg (or .git) directories in sync then during that sync you've got a remote store that's in an inconsistent state and doesn't know it.

Additionally both hg and git have a separation of what's local-only and what's remote-okay within their disk state. They know what info to share (example: commited changesets) and what not to (example: current, local working directory parent revision).

In other answers folks are saying "you'll probably be fine" or "I've never had a problem" and that's likely true, but it's not guaranteed true, and revision control isn't a place to play the odds. Use the proper, better, safer, more efficient, more full featured synchronization protocol for your source control system.
