TypeError on Safari in private mode

[m00s]

I have an angular application that integrates the print.io widget.
I'm using pio.latest.v2 script and I noticed that on Safari Version 9.1 (11601.5.17.1) on Mac OS it throws this error after the script is loaded:

TypeError: (localStorage).keys().filter(function(a){return 0!==a.indexOf("pio.")}).each is not a function. (In '(localStorage).keys().filter(function(a){return 0!==a.indexOf("pio.")}).each(function(a){return localStorage.removeItem(a),!0})', '(localStorage).keys().filter(function(a){return 0!==a.indexOf("pio.")}).each' is undefined)_

It may be related to how safari handle the LS in private browsing, it raise a QuotaExceededError: DOM Exception 22 only if you try to set a value, otherwise LS looks supported

def a bug. looks like we should've done Object.keys() instead of _().keys().

thanks! will get a fix out for it

[micahasmith]

in the interim i would recommend clearing your localstorage

[m00s]

I tried to clear it before but the error persists. Thanks anyway

[micahasmith]

@m00s should be fixed. let us know

[m00s]

Now I get a different error that is the one raised by Safari when accessing the LS in private browsing:

QuotaExceededError: DOM Exception 22: An attempt was made to add something to storage that exceeded the quota.

Here a screenshot of the line of code that throws the error, I'm using again pio.latest.v2, hope this can help..

[micahasmith]

ugh. sorry for the new issue.

@VSergiyenko -- can you ticket this one up for andrey, pls?

[vsergi23]

@micahasmith sure, I will

[micahasmith]

@m00s do you use a lot of localstorage on your site?

[m00s]

@micahasmith Not really.. not as much to reach the quota limit at least.

As I was saying this is a Safari specific error, raised only in private browsing.
You basically cannot try to set a value in the local storage in private mode.

Here a discussion QuotaExceededError: Dom exception 22

In my code I have a try..catch wrapping the very first LS access that looks for that specific error and do some extra configuration, the problem is that including pio.js I get the error in console as well.

[micahasmith]

we're going to wrap and suppress this one then.

[m00s]

@micahasmith Awesome, thanks.

Anyway, even if the error isn't breaking my app I'm redirecting users to a different application now, so I don't know if the widget is working or not.

Is the pio widget supposed to work even without the local storage?

[micahasmith]

eh, the ui works, but the cart storing doesnt.

but if this is an only safari private browsing issue, its not a concern in my book

@micahasmith We are having a lot of people browsing from iPads and iPhones in private mode, but yeah, I understand your point.

Thanks for the support!
