Can't update filters on Tablet

[findow]

I can't update filters on tablet: debugging remotely I have these errors in Console

AbortError (2)vapi-cachestorage.js:231:16
InvalidStateError: A mutation operation was attempted on a database that did not allow mutations. (2)vapi-cachestorage.js:231

Firefox Nightly updated yesterday, lastest Ublock development channel

[gorhill]

It's as if uBO's indexedDB was not allowed. You wholly disabled cookies, or some related setting in about:config?

[findow]

I have not changed any settings in about:config on my Tablet. Not at all.
EDIT: I have already tried uninstalling and installing.

[gorhill]

Private mode then?

[findow]

This happens at browser startup, before I can even start opening tabs.
EDIT: sorry but I was wrong, the errors happen at browser startup, before I even attempt to update the filters.

[gorhill]

This can happen if you are using permanent private mode. At this point you need to investigate on your side, I can't do this for you. Maybe share the information shown in about:support.

Got these errors while trying to update filters

[gorhill]

The other errors do not matter, only the first one matters. I will need about:support, if there is anything I can do, that will be only with this. If nothing comes out of this, report to Firefox devs,

Caratteristiche sperimentali

[gorhill]

I don't see anything in there. I don't know what to do at this point aside report to Firefox devs -- from uBO's point of view, the browser does not want uBO to get access to its own indexedDB database.

[findow]

Did I add too many filter lists?

[gorhill]

Did I add too many filter lists?

If this was the issue then there would be no error message just launching uBO?

But you can always try to un-check filter lists and see if this helps.

[gorhill]

Any news on this?

[findow]

Sorry for delay.
I have not reported the error on Bugzilla, but I discovered that QuotaExceededError is thrown from the onabort() method, but you only implemented onerror().
https://www.html5rocks.com/en/tutorials/offline/quota-research/#toc-how_to_handle_going_over_quota
That aside, when I get the error I have the same visual bug as in #3018

[gorhill]

but I discovered that QuotaExceededError is thrown from the onabort() method

So it would appear there is a limit to the amount of data uBO can save in indexedDB after all.

[findow]

It seems to be related to the free space on the device, but with the Legacy version I never had such a problem.
On https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Browser_storage_limits_and_eviction_criteria#Storage_limits it says that the limit is 50% of free space, but there is also a 20% group limit on said 50%.

[findow]

Is there anything else I have to provide?

At this point I see 2 roads:

1. Ask mozilla to increase the limits for low memory devices (tablet and smartphones usually have 4, 8 and recently 16GB of internal memory)
2. Compress (zip compress?) ublock cached assets before storing them

Whatever decision you take, could you implement onabort() so to make updating filters fail gracefully?
This way I can see if there are other errors in the console.

[gorhill]

I will add code to deal with onabort.

[jasoncook]

Is this issue strictly limited to tablets? I'm having a similar issue on Windows and FreeBSD clients:

A network error prevented the resource from being updated

[vladus2000]

I see the same issue as jasoncook on arch linux, release channel firefox. I have many of the filter lists checked.

[gorhill]

Please do not add noise to this issue. Network errors are unrelated to the issue here. Something is preventing uBO from fetching the lists on your side, investigate these network errors on your side.

[gorhill]

onabort handlers added with a264975.
