864834 - appcache cached event not firing

Status: RESOLVED WORKSFORME

(Core :: Networking: Cache, defect)

Description

[Mike Ratcliffe [:miker] [:mratcliffe] [:mikeratcliffe]]

Attachment: GCLI appcache commands

Running the tests individually works just fine:
./mach mochitest-browser browser/devtools/commandline/test/browser_cmd_appcache_invalid.js
./mach mochitest-browser browser/devtools/commandline/test/browser_cmd_appcache_valid.js

But no cached event is raised when running the tests in a batch (stopping the 2nd test dead): 
./mach mochitest-browser browser/devtools/commandline/test/

browser_cmd_appcache_invalid contains an invalid appcache. When prompted to allow this site to store offline content the allow button is clicked. Because the appcache is invalid an error event is raised as planned and the test runs through successfully.

browser_cmd_appcache_valid contains a valid appcache. Because the previous test allowed example.com to store offline data there is no prompt this time. The progress event is raised for each appcache file downloaded and I do see the console message "Offline cache update done, URL=http://example.com/browser/browser/devtools/commandline/test/browser_cmd_appcache_valid_appcache.appcache." The only problem is that the cached event is not fired.

I'll take a look.

Is this intermittent?  For me the whole site or when I leave just those two tests in the dir pass OK.

I +1 this in FF 24.0 for desktop (win). It works on FF 24.0 on Android.

Closing based on comment 3.  If this is still an issue please reopen.

This is the code I use :

//Manifest event handlers
var appCache = window.applicationCache;
appCache.addEventListener('cached', function(event) {
	alert("The resources listed in the manifest have been downloaded, and the application is now cached.");
}, false);
appCache.addEventListener('updateready', function(event) {
	alert("The resources listed in the manifest have been newly redownloaded, and the script can use swapCache() to switch to the new cache.");
	window.applicationCache.swapCache();
}, false);
appCache.addEventListener('noupdate', function(event) {
	alert("The manifest hadn't changed.");
}, false);
appCache.addEventListener('obsolete', function(event) {
	alert("Unable to download the Manifest.");
}, false);
appCache.addEventListener('error', function(event) {
	alert("Unable to download the Manifest.");
}, false);

When I visit my website for the first time an updateready event is fired instead of a cached event. I can reproduce this bug on Firefox 32.0.3 / Windows 7 64bits and on Firefox Mobile 32.0.3  / Android 4.4.4 / Nexus 7.

Of course, I get an error with the swapCache() probably because there is nothing to swap(InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable). If I load the website another time then a noupdate event is fired and everything works fine. It means that the manifest had been cached the first time, unfortunately no cached event is sent.
