Where "Firefox" means official release. We unfortunately can't do: #if MOZ_UPDATE_CHANNEL != release && MOZ_UPDATE_CHANNEL != beta (or #if !defined(MOZ_UPDATE_CHANNEL) || MOZ_UPDATE_CHANNEL == nightly || MOZ_UPDATE_CHANNEL == aurora) GeckoSmsManager.java handles correctly the absence of those permissions so there is nothing to do in this area.

Actually, opt-out seems better so devs will have the permissions enabled for their own builds.

Mounir, one quick question for you --- does the DOM spec say anything about error behavior when SMS capabilities are present on device, but possibly disabled? If we continue going the route of disabling sms at the last possible second here, that's going to allow script to see a navigator.sms object, but it'll be useless. So a user might run an sms app that looks like it should work, but doesn't ever do anything. I'm asking because, I wonder if we should make navigator.sms return null for the sms-disabled case here.

My guess is that should behave like SMS permissions not being granted (in the Web App sense, not Android one) but we don't know yet if we are going to have a one SMS permission or multiple ones. In the former case, it navigator.sms might return null, in the later, we will very likely throw error events like geolocation is doing. I do not mind having all SMS methods throwing an error event even if there is an SMS object. What I would mind is to write very specific code just to handle that very specific case. > I'm asking because, I wonder if we should make navigator.sms return null for > the sms-disabled case here. If Brad is okay with the code being built but never used, that is a viable solution: it doesn't add any new code path, it just requires a #ifdef somewhere.

There have been discussions to have that kind of behavior for web facing experimental API instead of prefixing.

We do not allow the code to throw, it can throw. If it throws, we send an error event to the DOM, there is no hack. If by disabling the whole implementation, you just want to be sure that we never run that code (without making it not compiled), we could do that but I do not understand why you prefer this over removing the permissions.

To make things clearer and improve the decision making process, I've distinguish the two issues we have here and the different solutions. The first issue is on which builds/channels we want this to be enabled. The different solutions are: A. Disable everywhere except when building for no channel (MOZ_UPDATE_CHANNEL=default) - very hard for anyone to test the feature B. Allow also in Nightly + feature is testable in Nightly (behind two prefs) C. Allow also in Aurora + we increase number of people who can test the feature D. Allow in Beta and Final - it reaches the market, people are going to scream... I agree that D is clearly not doable. I do not see any reason to no try B or C. I admit that having Aurora coverage isn't highly required so I would be fine with B. I really don't like A because that would highly reduces the chance of anyone trying out this experimental feature (getting a build from our build bots or running a build on try is too complex). I think B is a good compromise between making clear this feature isn't going to ship and still allowing it to be testable. The second issue is *how* to disable this feature. The different solutions are: 1. Do not grant Android SMS-related permissions -> the API is usable but will always produce an error + very easy to maintain - binary has code for something that isn't allowed to success but can run 2. Make Android not supporting SMS (ie. treated like other platforms) -> the device will be shown as not capable of handling sms (navigotr.mozSms will be null) + easy to maintain - binary has some consequent amount of code that can't run 3. Disable the entire feature -> WebSMS will not appear to be implemented by the UA - hard to maintain (lot of #ifdef MOZ_WEBSMS) + binary do not bloat My first take was to go for (1) because it was the best way to show that WebSMS isn't working on Beta and final because the permissions are not granted. If we stick with solutions A or B, we don't need that kind of feedback. In that case (2) or (3) could make sense. I think (3)'s major disadvantages can be fixed if we have both code paths being run. I mean that on m-c we could have Android builds building with --enable-websms and non-Android builds building with --disable-websms. Thus, we are sure that both paths are always maintained. Between (2) and (3), I'm not sure which one would be the best pick. Usually, we try to have Gecko for Firefox Desktop and Gecko for Firefox Mobile to be the same but here, that might be useless to have a feature being built for all platforms while only one will use it (two, with B2G). So maybe we could try (3)? So, Brad, can we try to find a common ground with these data? B3 seems like a good compromise between your concerns and mine.

The message passing function has a return value, you could just check that return value from the caller and throw the error there. In fact you should anyway, this really shouldn't be any additional code in the end. > If by disabling the whole implementation, you just want to be sure that we > never run that code (without making it not compiled), we could do that but I > do not understand why you prefer this over removing the permissions. I see no need to build code for a feature that we don't want in the product. Your explanation of the error handling further convinces me of that.

3 certainly seems to be the way to go here. The A, B, C, D discussion doesn't really have to happen in this bug. There should be a configure flag which the mozconfigs that control what's in nightly/aurora/beta/final can set.

Do not grant Android SMS-related permissions > 2. Make Android not supporting SMS (ie. treated like other platforms) > 3. Disable the entire feature This decision is an issue of web API semantics when the API isn't implemented by a particular platform, and that semantic decision is orthogonal to code maintenance. I'm told that semantic preference is to return null from unimplemented APIs instead of ifdef'ing it out to the point where it's |undefined|. So that argues for (2) above. Jonas needs to sr that, since it's a problem of the DOM module. On android, we obviously need to ifdef out the permission request with any of those three options. Beyond that, with option (2) it's not terribly critical what else is ifdef'd out, because all the android-backend code is unreachable. What's the minimal patch maintenance-wise that gets rid of geckosmsmanager? Brad, if we use the isSmsEnabled() helper you proposed in bug 674725, and then never create the geckosmsmanager singleton (so it remains null and any attempt to access it throws), does that satisfy your concerns? Mounir, that should be simple to hack up --- can you give that a shot while we keep discussing here?
Mounir, also we need tests for the sms-disabled state, that can start running on tinderbox now.

Something like this: App.java.in: public void handleMessage(String event, JSONObject message) { #ifdef MOZ_WEBSMS if (event.equals("WebSMS")) { GeckoSmsManager.handleMessage(event, message); // <-- static method return; } #endif super.handleMessage(event, message); } and then the makefile can build GeckoSmsManager.java conditionally Makefile.in: ifdef MOZ_WEBSMS JAVAFILES += GeckoSmsManager.java endif

Basically this makes navigator.mozSms returns null if --disable-android-websms is used. Whether we do and how we do prevent building GeckoSmsManager.java should be done in a follow-up I believe. (In reply to Chris Jones [:cjones] [:warhammer] from comment #12) > Mounir, also we need tests for the sms-disabled state, that can start > running on tinderbox now. All tests I wrote are assuming sms isn't supported because Android mochitests are only a subset of mochitests (so they don't run this test unfortunately) and testing WebSMS methods isn't doable yet and should be in the scope of Marionette I believe.

I prefer to keep WebSMS backends enabled by default. If Firefox Mobile doesn't want that feature in any channel, that's another story and we can add --disable-websms-backends in the appropriate mozconfigs. At least, keeping enabled by default guarantees us that the code doesn't bitrot...

Which means we are going to require App.java to call GeckoSmsManager. That design should work but seem odd to me because we would just move methods from GeckoAppShell.java in App.java thus increase the boilerplate. Why GeckoAppShell.java shouldn't be preprocessed?

I do not understand how this is going to solve the problem because we are still going to do a runtime check: if (ISmsManager.get()) { ISmsManager.get().foo(); } (or something similar) In addition get() is going to be declared as returning a GeckoSmsManager object but this declaration will fail if GeckoSmsManager.java isn't compiled. In addition all methods colled in GeckoAppShell.java and GekoApp.java will not be declared in ISmsManager.java but in GeckoSmsManager.java. We could fix that by havinig ISmsManager declaring all methods and forwarding them to GeckoSmsManager if MOZ_WEBSMS_BACKEND is defined. Though, that would be quite a huge boilerplate. An alternative would be to have a GeckoSmsManager.java file and another GeckoSmsManagerFallback.java and we would compile one or the other depending on MOZ_WEBSMS_BACKEND. This solution might work but this is going to grow significantly the amount of code and paths to maintain so I really wonder if it's really worth doing it compared to just always compile GeckoSmsManager.java.

I don't understand how that would work. javac will only emit Foo.class from a Foo.java source file.

Comment on attachment 586076 [details] [diff] [review] Part 2 - Don't build GeckoSmsManager.java is WebSMS backends are disabled Review of attachment 586076 [details] [diff] [review]: ----------------------------------------------------------------- I am assuming that the changes to mobile/android and mobile/xul are the same. When ISmsManager is null, I wasn't completely sure what the return codes should be from GeckoAppShell. I attempted to apply this patch and it has bitrotted a bunch. I couldn't build or test with it. Please update the patch and make sure you don't break the build or anything fun like that. So, r+ with: The copyright date fixed.

We already have real interfaces in our code that aren't prefixed: http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/gfx/InputConnectionHandler.java Also, why not just use a real interface type?

Requesting tracking-firefox11. We need to fix this before Firefox 11 Beta is published to the market.

it looks like aurora doesn't have the SMS related permission requests, so we don't need this there
