See bug 756644 for a overall description of what we're needing to do here. This bug is specifically for implementing the ability to all the appcache to be "per app" rather than just per site. I.e. we should be able to key app-cache on "app" in addition the just the manifest url we're currently keying on. The most basic use-case is if you install two browsers in Firefox and AwesomeBrowser on a B2G device. If you use Firefox to browse to a website which uses appcache, and then switch to AwesomeBrowser to the same website, we will use different cookies when browsing with AwesomeBrowser, hence we should also use a different appcache.

Honza, if you're ready to take this you'll want to apply my patches for bugs 775119, 775860, and 775861 (in that order) so you can grab the appId and isInBrowserElement from channel's callbacks (nsILoadContext). I'll add NS_GetAppId and NS_GetInBrowserElement methods to nsNetUtil.h in a sec. Also, assuming nsHttpChannel winds up using these values in multiple places, it might be worth caching them in HttpBaseChannel::SetNotificationCallbacks (like I already do for mPrivateBrowsing in my patch).

Sicking, My understanding is that we want a separate appcache for each {appID, isInBrowserElement, origin} combination (where appId=0 means use the default global appcache--i.e. for desktop: appId=0 means we use the existing appcache). Correct?

per discussion with jonas, I'm going to grab nsScriptSecurityManager::GetExtendedOrigin and put it in nsNetUtil.h, and that will generate a string that we'll use as the per-appcache id. Patch coming...

Honza: Any chance you can take this? Sorry that communication appears to have gotten messed up somewhere. This is really the highest priority appcache bug for B2G since appcache won't work on B2G at all without this bug. I've poked Josh to clarify the priority for this, not sure where communication failed at last attempt :(

So GetExtendedOrigin() in nsILoadContext returns the key for namespaces for appcache/localstorage/IndexedDB. I've added a convenience method NS_GetExtendedOrigin in nsNetUtil to get it in my patch for bug 776176.

First draft, basic set of offline cache tests for the usual web content is passing, so at least it seems nothing is broken with this patch. Feel free to test manually, but I don't guarantee any functionality now. I'll write tests. What is the best test to inspire with?

I have updated this patch locally. I wanted to a) save implementation of nsILoadContext in offline cache update parent and b) prevent use of ssm in necko/uriloader by turning the app cache apis to use directly the extendedOrigin string. But thanks heaviness of usage of such api it doesn't seem to me as a good way. I'd like to let app cache service take nsILoadContext and work with it directly rather then with some final ID that consumer has to correctly generate. "Generate" here means to let that ID be empty when origin == extendedOrigin, that is currently impossible to detect in a convenient way and w/o dep on ssm interface (see [1] and "GetJARIdentifier" function). I am deciding whether origin == extendedOrigin on too many places wide in the code (in a quick and very hacky way just to check the appcache code works) in the updated patch. So really not a way to go. Thus I'm completely blocked on how bug 777720 is about to evolve. If we add some way to recognize extended origin from origin on that interface, then I'm happy. [1] https://bugzilla.mozilla.org/attachment.cgi?id=645778&action=diff#a/netwerk/cache/nsDiskCacheDeviceSQL.cpp_sec2 PS: I cannot decide whether extended origin is just origin by creating and comparing origin of e.g. manifestURL (or some same-origin URI where available) again w/o ssm.

If you keep and store a LoadContextParent (from bug 777419) you can keep an nsILoadGroup around in the parent (or child), and ask it whenever you want for extendedOrigin and it will generate it for you (it lives in /docshell so no issue about calling ssm from /necko). Is that good enough?

Is that good enough? Jason, this absolutely doesn't address my concern. Yes, it is good, that we now can easily have load context on the parent, good job! But my concern is different: how to recognize that extendedOrigin is extended w/o ssm.

Oh, and keep in mind that we need to be able to delete data on a per-appid basis when sn app is uninstalled.

If we have a mapping of app to appcache manifest url (AFAIK we do), then it is doable with what I'm locally tuning.
Reporter | ||
Comment 12•12 years ago
|
||
That's not enough. We're not just talking about the appcache used to cache the app itself. For example the B2G Firefox app can allow several websites to be cached just as they are in Desktop firefox. These websites can have arbitrary URLs, however they will all have the Firefox appId. If the user uninstalls Firefox, we want to remove all data associated with Firefox (since it's useless as it can't be reached from other apps). Hence we want to remove all appcached data with the Firefox appid. This doesn't just apply to Firefox of course, but to any browser app installed by the user.

Jonas, what's our design for uninstall notifications? A new nsIObserverService notification? Is it implemented/documented anywhere?
Reporter | ||
Comment 14•12 years ago

We don't have anything designed yet. But yes, I think we should do it as a nsIObserverService notification.

Jonas, OK. Then I'm not quit sure how this is going to work. Say we have: <iframe mozbrowser src="browser-URL"> <iframe mozapp src="app-page-URL"> <html manifest="manifestURL"> Then the app at app-page-URL that invokes the app cache update will have isInMozBrowser=true and appID=some:app:id. How can I recognize that the app at app-page-URL is installed by a browser at browser-URL using just load context? As I understand, the groupID then should be consisted from manifestURL + '#' + [true /*mobrowser*/] + browser-URL + some:app:id. We can then search for #true+browser-URL to gather all entries belonging to that browser, is that what you mean? At the moment I don't know hot to get the "browser-URL".

Say we have: > > <iframe mozbrowser src="browser-URL"> > <iframe mozapp src="app-page-URL"> > <html manifest="manifestURL"> FWIW, right now this is a theoretical construct. The contents of the toplevel iframe here is a webpage, and webpages doesn't have access to create mozapp iframes. Only very high privileged apps are allowed to do that (essentially only the "window manager" app on B2G). But assuming that changes at some point in the future... > Then the app at app-page-URL that invokes the app cache update will have > isInMozBrowser=true and appID=some:app:id. Actually no. A <iframe mozapp> always acts like a hard boundary for any behavior. So the page at app-page-URL will have isInMozBrowser=false. > How can I recognize that the app > at app-page-URL is installed by a browser at browser-URL using just load > context? Which means that you don't need to do this. > As I understand, the groupID then should be consisted from manifestURL + '#' > + [true /*mobrowser*/] + browser-URL + some:app:id. No, the groupdID will be manifestURL + '#' + 'f' + some:app:id When the app is uninstalled you'd have to delete all appcaches with groupIDs which end with 'f' + some:app:id and 't' + some:app:id.

- nsIApplicationCache.groupID is no longer just the pure manifest URL and cannot be used for that purpose - based on the previous point, added nsIApplicationCache.manifestURL attribute and used on proper places - groupID now consist of manifestURL + appid + {f|t} - there is a new method on nsIApplicationCacheService that builds a groupID from manifestURL and nsILoadContext - #define NECKO_NO_APP_ID 0 in nsNetUtil.h to avoid using ssm in necko/uriloader - should update to use new loadcontext implementation from bug 776174 ; can be done later, though

Not clear to me how this is getting QI'd or whatever to a nsILoadContext--for necko channels it was via GetInterface, so it's easy to just hand off mLoadContext when something asks for nsILoadContext. If this case is similar you can simply avoid having OfflineCacheUpdateParent inherit from nsILoadContext and just hand out in GetInterface.

But I maybe just need more context on how the autoupdater is going to work. > We just need to to add another Schedule() to pass AppID & isBrowserElement > as args for auto-updater if nsILoadContext been implemented at > nsOfflineCacheUpdate. Probably yes, or some other mechanism that will pass fake load context. Also, what you suggest, a bit sounds like we could have some nsIWebAppInfo or so interface that would provide just the two isinbrowser and appid. (In reply to Jason Duell (:jduell) from comment #20) > Comment on attachment 647475 [details] [diff] [review] > wip2 Thanks as well. > Pass a IPC::LoadContext instead of isInBrowser/appId.

Since I have no more time to update this (I will have to work tomorrow few hours anyway, but probably won't get to this one particular) somebody else has to finish this. I suggest Thinker to do the updates and let Jason review it. You two should also talk a bit about the autoupdater, what might be the best land-preparation for it and if it has to be done in this patch/bug (I think a followup is sufficient).

Comment on attachment 647475 [details] [diff] [review] wip2 Thinker, So do you think this patch good enough to land for now? My impression is it's OK: it passes tryserver, and while there are some code cleanups to be done, nothing is broken. Is that a correct reading of your review in comment 19? If so I'd like to land this and then I can code the IPDL cleanup stuff in a followup bug, and I know a reviewer who's fine for that review.

unbitrotted stdint and other things. Still passes try, ready to land AFAICT but holding off until bug 786835 lands, as same issue that blocks cookie-jars from landing (need same necko namespace but currently using inBrowserElement) would break appcache too.

The only semantic change here is the nsILoadContext now has a GetTopFrameElement method. Apparently returning NS_ERROR_UNIMPLEMENTED isn't enough... https://tbpl.mozilla.org/?tree=Try&rev=c447fdbe34ce

The only failure the v4 of this patch was causing was failure of one check in test_offlineMode.html. A day or two before we pushed v4 patch to try nsIOService.offline attribute meaning has slightly changed in bug 87717 and some offline cache update when nsIOService.offline = true simply didn't fail as expected. The offlineMode test was enabled just by mistake in the patch, normally is disabled. v4.1 - v4 = leave offlineMode test disabled.

Thank you. Sorry for taking so long to get back to you on this. I tried installing a web app that preloads the appcache here - http://people.mozilla.com/~fdesre/openwebapps/test.html and then cut the network. Then, I launched the app. The contents loaded successfully. Smoke tested this feature with the following cases: PASS - Install an app that preloads the appcache - verify that the app loads on launch without a network connection PASS - Go a site in the browser that populates the appcache for the web content. Then, install an app that preloads the appcache that references that same web content. Then, uninstall the app. Verify that going to the web content again in the browser without a network connection should still be viewable. FAIL - Install an app that preloads the appcache for content off of X site in the browser. Then, cut the network connection. Now, go to that content in the browser. Verify that an error is reported that the content is offline. The last test didn't pass for me - as I instead got the content preloaded for a different app to load, which I thought shouldn't work in this case. Did I do something wrong? Or is this a bug? For reference, the test app I was using is here - http://people.mozilla.com/~fdesre/openwebapps/test.html with "install app with appcache". The relevant URL is http://people.mozilla.com/~fdesre/openwebapps/app.html for the content that's loaded that also makes use of appcache.
