localStorage takes a lot of time to save the values

[costales]

Hi!

I'm using localStorage HTML5 for read/save the user preferences in GPS Navigation.

It's working, but it's taking (random time: 3", 5", 10") to really save those values.

Testing:
- Install my attachment.
- Running from the SDK the click numbers are OK. You can restart the app and the clicks will be OK.
- Running from the mobile if you click from 5 to 10 clicks the button and you kill the app fast, the next clicks will be 5, not 10. You have to wait a lot of seconds for real save that value.

For the test, I added to a normal HTML5 app in the SDK with this HTML5 code: http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_webstorage_local_clickcount

Thanks in advance!

Status changed to 'Confirmed' because the bug affects multiple users.

@Olivier: I really think is not related to the bug #1456267.
The problem is:
- Webview is getting the values in the moment: In my attachment, you click on button and is getting the current clicks done.
- Webview is not storing the values in the moment: In my attachment, you can wait 2" and kill the app. In those 2", the app didn't save the values.
Thanks in advance!

Marcos: and I’m pretty sure it is :)
What you’re seeing is the localStorage data not being written to disk synchronously, but only periodically. If you kill the app before the data has been flushed to disk, it won’t be persisted. This is fixed in oxide 1.8, to be released soon.

Great :) Now I understood the problem :) Thanks a lot Olivier!
