Description

The providers return an error code that says we're offline, when the compose window code tries to do an upload, but the compose window code expects to get the error in the onStopRequest call. I think the compose window code should expect the error right away.

yikes, that compose attach code doesn't want to work that way. Maybe I will go the onStopRequest route, or just check if we're offline in the compose code and not allow filelink while offline.

I've decided to hide the filelink ui while offline because we don't have a string for telling the user that they can't do a filelink because we're offline. And I suspect this is probably a better experience anyway (but asking for UI review anyway).

I've also fixed the handling of the offline state in the providers and the nsMsgComposeCommands.js code for correctness sake, but if the ui is enabled while offline, we get the generic "an error occurred", which is not a nice experience.

But are you considering to change this behaviour for upcoming releases, ie when the string had a chance to land ?

See my previous comment. I gave my opinion (no) but asked for Blake's opinion.

Review of attachment 613794 [details] [diff] [review]:
-----------------------------------------------------------------

This looks mostly good - though, I think there's another point where we use uploadFile that'll need to be wrapped in a try/catch - that's in convertListItemsToCloudAttachment.  That should probably be included.  Modulo that change, r=me.

As you and Jb mentioned, it'd probably be good to handle the offlineErr case with a new string.  I think we should prepare a separate patch for comm-central with that new string.

Also, this behaviour should be tested.  I can take care of that.

Also, I did everything *but* add a string, so if we decide we want to leave the UI enabled, but show an error if the user uses the UI, then we just need to add a string and a case to the error handling switch statement.

But I'm completely unconvinced that we should enable UI that we know isn't going to work. The general Thunderbird practice is to disable or hide UI that won't work when we're offline, though we're not consistent about it.
Oh, David - one last thing - it looks like we also return offlineErr in refreshUserInfo and deleteFile.  Will those need to be updated?

Actually, remind me again why we're not calling aCallback.onStopRequest(null, null, Ci.nsIMsgCloudFileProvider.offlineErr) from within the uploadFile functions?

because the calling code needs to handle the call failing synchronously in general (not just the specific case of being offline); it can't count on the call failing and being so kind as to call onStopRequest for a synchronous failure (e.g., some unexpected js exception). In this case, the request hasn't even started, so requiring onStopRequest calls seems like a byzantine way of doing synchronous error notification.

Yeah, thx, I noticed the deleteFile and refreshUserInfo cases and changed them to throws.

When I'm offline, attaching a large file still shows the notification bar.

Hitting "Link" gives:
JavaScript error: chrome://messenger/content/messengercompose/MsgComposeCommands.js, line 1234: '<error>' when calling method: [nsIMsgCloudFileProvider::uploadFile]
JavaScript error: chrome://messenger/content/messengercompose/MsgComposeCommands.js, line 1227: NS_ERROR_MALFORMED_URI: Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIFileProtocolHandler.getFileFromURLSpec]

And going offline while trying to attach a file seems to result in the spinner forever spinning…

/me mumbles something about tests to catch this kind of "switch to offline in the middle of the operation" behaviour.  ;)

After failing to upload a file, when I go back online, the "Convert to" menu item remains greyed out.

I think I'm going to have to say ui-r- because of those problems, but I'm sure you'll fix them for the next patch.

Thanks,
Blake.

I've got a fix for that.

I could be wrong, but that sounds like a necko issue - I suspect it's beyond this bug to fix. If we're not getting told that the request failed, it's hard for us to do anything. But I'll try it and see.

failing to upload because you went offline in the middle? That just sounds an other symptom of not being told the request failed, not anything to do with this patch.

disable attachment notification when offline

I could not duplicate the going offline while uploading error you saw - I got an error message about not being able to upload the file, and the spinner stopped. This was on windows; perhaps the mac networking code isn't as good with error propagation :-)

fix enabling of attachment context menu after errors

This may not help you, Blake, if you're not getting the spinners to stop, but when I try this, cancel remains enabled, among other things. Turns out the compose window isn't handling errors on upload other than cancel. This seems wrong to me - the only difference between cancel and the other errors is that we shouldn't put up an error message. That's what this patch does; mconley, do you think you could review the interdiff between this patch and the one that Blake ui minused (sob!)?

I wonder if the difference is that I'm uploading two files at the time I'm going offline?  (I just noticed that.)

When I do that, the first one does give an error, but the second file spins (though I can cancel it). I'll see if I can fix it.

-----------------------------------------------------------------

So this test causes two tests to fail in test-cloudfile-attachment-item.js (woo - the tests paid off! :D )

STR:

1)  Upload a file
2)  Try to cancel the upload

What happens?

An empty confirm dialog comes up.

What's expected?

No dialog - the upload should just stop.

Maybe fix this to be a @throws while you're here?

Here's the problem - when we break out of this switch, we still spawn a confirm no matter what.  In the case of uploadCanceled, it's an empty confirm.

Can we line up aProvider so that the "a" falls beneath the "i" in item.attachment?

sorry, I should have mentioned that I fixed the empty confirm last night...
Hm, remember those tests I were talking about writing?

I don't think I'll be able to do them.  Messing with Services.io.offline is bad because Mozmill / JSBridge depends on a network connection being open to communicate.

Mocking out nsIIOService2.offline also seems to be an all-around bad idea.

So I think we might just have to take this one on manual testing.  :/

I thought that was fixed somehow in mozmill.

fix mozmill errors, going offline with pending uploads

for some reason, MockCloudfileAccount didn't have the nsIMsgCloudProvider constants defined, so when I made cancel go through the switch statement in MsgComposeCommands.js uploadListener onStopRequest, it complained about this.cloudProvider.authErr not being defined. Ah, and the reason it worked for cancel is that the MsgComposeCommands.js code used Ci.nsIMsgCloudFileProvider.userCanceled instead of this.provider.userCanceled. The tests giveth, and the tests taketh away :-)

To avoid repeating ourselves, we can retrieve these from the interface, like:
