iOS8 & indexedDB

[ocombe]

It seems that Apple screwed up the iOS8 indexedDB implementation: http://www.raymondcamden.com/2014/9/25/IndexedDB-on-iOS-8--Broken-Bad
Do you know if there is anything you could do to prevent iOS8 from using indexedDB, until this problem is resolved ?

You can probably somehow detect the browser and use setDriver, as found in the docs.

Oops half post...
... But I'm not aware of any iOS 8 browser detection script yet that's also considered production ready.

Definitely a bummer! Feature testing is obviously preferred, I'll look through to see if there's something they do that we can test against other than just a User Agent.

If IndexedDB is too broken to use I'll leave WebSQL as the default driver for iOS 8.

Since it's the first and only iOS with indexedDB, the user agent test should be pretty easy (just prevent all iOS from using indexedDB ?)

[tofumatt]

Right, but I'd prefer not to do that, as things like Cordova/PhoneGap might not report the right UA but have access to a WebKit with IndexedDB. We'll only use UA if there's no other way.

[ocombe]

Oh yes, you're right, I didn't think of that :)

A nice thing to discover on Friday...

We wrote an isolated test you can use to detect the broken functionality in iOS 8 and Safari 7.1. It detects the issue with being unable to open two object stores at once, although not the issue of keys overwriting each other.

Unfortunately in PouchDB we just fell back to user agent sniffing, because we needed a synchronous test rather than an async one.

[tofumatt]

Oh, nice. I think we can manage an async test, though I wonder if UA sniffing is much faster...

Yeah. FWIW we use

var isSafari = typeof openDatabase !== 'undefined' &&
    /Safari/.test(navigator.userAgent) &&
    !/Chrome/.test(navigator.userAgent)

That openDatabase test is because IE Mobile now masquerades as Safari in their user agent.

Has anyone been able to test this on iOS 8.1 yet? I am experiencing these problems as well, but haven't been able to test in iOS 8.1 so far.
