Own block rules lost after update to v. 1.0.0.3

[ghost]

Unfortunately, the "Your block rules" window is empty now. I assume that this problem might be related to the FileSystem API change?

Crap.

I just reviewed the code and I can't see why it wouldn't work. Will keep looking but it's kind of too late at this point, there is no way back.

If you have a back up, restoring should work fine though.

Yes, I was able to restore them.

BTW, I forgot to mention that I also have some allow rules in ABP syntax which I forgot to remove in HTTPSB - they "survived".

Ok so if I understand, before the restore, the block rules were gone, while the allow rules were properly converted to the new storage?

Exactly!

[gorhill]

Ok. I see potential for a race condition, where there is an attempt to load data before it has been saved. If so, this means that your data was properly converted, but somehow the actual writing of bytes to the storage did not occur before the data was requested.

I need to fix this.

The workaround meanwhile in case other users end up with the same problem is a simple restart of the extension (disabling/enabling).

I didn't think of this workaround. Too late to test it now ...

Actually, correction:

The data was irremediably lost. Whichever "block" or "allow" rules was saved first was clobbered if both fields had rules.

I can still save Opera users I think.
