ostrio_files.js error when using opera

[sebastianlutter]

When I try to test an application on Opera 12.16 Build 1860 (Debian 8, x86_64 system) I get an client error in ostrio_files.js line 1647:

Unhandled Error: Cannot convert '_URL' to object
											this._webWorkerUrl = _URL.createObjectURL(new Blob(['"use strict";self.onmessage=function(a){if(a.data.ib===!0)postMessage({bin:a.data.f.slice(a.data.cs*(a.data.cc-1),a.data.cs*a.data.cc),chunkId:a.data.cc});else{var b;self.FileReader?(b=new FileReader,b.onloadend=function(c){postMessage({bin:(b.result||c.srcElement||c.target).split(",")[1],chunkId:a.data.cc,s:a.data.s})},b.onerror=function(a){throw(a.target||a.srcElement).error},b.readAsDataURL(a.data.f.slice(a.data.cs*(a.data.cc-1),a.data.cs*a.data.cc))):self.FileReaderSync?(b=new FileReaderSync,postMessage({bin:b.readAsDataURL(a.data.f.slice(a.data.cs*(a.data.cc-1),a.data.cs*a.data.cc)).split(",")[1],chunkId:a.data.cc})):postMessage({bin:null,chunkId:a.data.cc,error:"File API is not supported in WebWorker!"})}};'], {
												type: 'application/javascript'//
											})); //
										})

The command in the next line (1646) sets _URL to undefined, which obviously causes the error on line 1647:

_URL = window.URL || window.webkitURL || window.mozURL; //

Versions:
Meteor 1.4.2.3
ostrio:files@1.7.5

This only happens in Opera, the application runs well on Firefox, Chrome.

Hello @sebastianlutter

Thank you for report, sorry for delay.

1. Is this Mac, Linux or Win?
2. Which Opera version?

[dr-dimitru]

Tested on Mac Opera (43.0.2431.0) and (41.0.2353.69), can't reproduce

1. Is this Mac, Linux or Win? Debian 8, x86_64 system
2. Which Opera version?

user@work:~$ sudo apt-cache show opera
Package: opera

This will be fixed in next release

[sebastianlutter]

This is the result of _URL when I ran in operas console:

>>> _URL = window.URL || window.webkitURL || window.mozURL || window.msURL || window.oURL || false;
false

Then the condition the line after would be false

if window?.Worker and window?.Blob and _URL

I have no understanding of the surrounding code, is this what you expected?

[dr-dimitru]

Yes,

Basically, BlobBuilder is not supported, so it will fall-back to request Worker code over the wire.

Hi @sebastianlutter

Published as v1.7.6
Could you please update, and confirm as fixed on your end?

[sebastianlutter]

updated to v1.7.6, confirm it is working now (Opera 12.16.1860 on Debian 8)

Thanks :)
