640803 - Error while syncing: corrupt history

Status: RESOLVED WORKSFORME

(Firefox :: Sync, defect)

Description

[Jon Mitchell]

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Firefox 4.0 RC 1

I get an error bar every time Firefox tries to sync: "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action." Issue persisted after complete delete/restore of account. Firefox Home on iOS does appear to sync, though, but error still shows up on desktop browser.

Reproducible: Always

Steps to Reproduce:
Every sync, automated or manual, produces this error.
Actual Results:  
Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.

Expected Results:  
Synced, and perhaps notified me that the sync was complete.

These two lines from the log seems relevant:

1299799397534	Service.Main	DEBUG	history failed: database disk image is malformed No traceback available

1299799397627	Collection	DEBUG	POST success 200 https://scl2-sync28.services.mozilla.com/1.0/nikhkt4zk6zaf6sfr6wnt45ooc4zoqyk/storage/tabs
1299799397641	Service.Main	DEBUG	Exception: Some engines did not sync correctly No traceback available

If the log item is accurate, there's nothing Sync can do about this -- your profile (in particular your history) is corrupt.

What happens if you click History > Show All History?

My history is there, but your pointing that out might actually give me a solution, and it's entirely a user-end problem. I previously tried to clone my Firefox program files across two OS-level users, so my browser would be the same on both accounts. I clearly corrupted the history by doing that. I'll try to find and undo the damage I did there, and see if that clears it up.

Yep! You can probably close this bug. Check this out: I synced, despite the error, since I knew it worked on FF Home, then I trashed my program files entirely and ran Firefox like new. Then down-synced my data, and it worked just fine. This is something I introduced at the OS level. It's not something your code will ever do to anyone, so you can probably disregard.

Thanks for alerting me to the history problem!
