unexpected warning : shard.rs:106: Invalid batch: found batch start inside batch

i18nsite opened this issue · 6 comments

I'm writing a command line application. When my program exits, I use keyspace.persist(FlushMode::SyncAll)?;
I not close the database (is there a shutdown function?)

The following warn occasionally appears at 2 times start my cli. ( video https://www.loom.com/share/c1c1a71d06fb495bad85bacda73b219e )

Is there a way to block this warning?

When my program exits, I use keyspace.persist(FlushMode::SyncAll)?;

On Drop, flush is called automatically https://github.com/fjall-rs/fjall/blob/main/src/keyspace.rs#L80

I not close the database (is there a shutdown function?)

Dropping is the shutdown function. You can check trace logs to see if the keyspace is properly dropping in your application.

Is there a way to block this warning?

I may need to adjust the verbosity of some of the logging. Depending on the logger you use, you may be able to set a filter though.

I have adjusted the logging levels to be debug and trace in the next version

@i18n-now Looks good to me, do you expect different logs? The missing terminator, but last batch logs are to be expected, I think with V2 I will be able to get rid of them... but they don't necessarily indicate data loss.

I see , I thought it was a problem with my usage that caused the error.

If the data is automatically written when dropped, why is there still a warning?

I would expect a way to explicitly avoid this prompt, as the data being possibility correct also means there is a possibility of loss.

Losing data is quite terrifying.

Additionally, I am using fjall as a cache in my translation tool (which is still under development): https://github.com/search?q=repo%3Ai18n-site%2Frust%20fjall&type=code

The project is currently under development, and Fjall is very useful ^_^.

I hope there can be a performance monitoring comparison that can monitor the performance of each version.

That's a bit of an oversight on my part, it's not critical, but it would be a breaking change to "fix" it. So it's gonna be a data format V2 change.

Me too honestly, it's not 100% transparent right now, but it's fixable.

I planned on adding something like this, but it's a bit of effort to setup. I didn't know about that GH action, thanks for sharing!
