I'm trying to help some users of my extension with a problem.
Unfortunately I can only offer suggestions of things to try and then
wait for a reply.
I asked one to put this code in the web console and tell me what happened:
try {
var request = indexedDB.open('thisIsATest', 1);
request.onsuccess = console.log;
request.onerror = console.error;
request.onblocked = console.error;
request.onupgradeneeded = console.log;
'finished';
} catch(ex) {
console.error(ex);
}
What you'd expect to see on the console is either "finished" and then
one or more messages from the event handlers, or an error from the catch
block.
What they got instead was: undefined.
This surely must mean that indexedDB.open is failing but not throwing an
exception. I've tried disabling indexedDB, or making the appropriate
directory read-only, but in both cases an error is reported (even if it
is, helpfully, "UnknownError").
So I'm stuck. What could be causing this, and what can I do about it?
