We got one of the updates to fail:

I believe we got a 503 when trying to download the update from stage/ftp.

chmanchester: how can we make firefox-ui-updates retry few times? That would be in case aus is not available at the moment.

chmanchester: I also attached a patch that makes us fail faster (instead of waiting 5 minutes).

You can test this patch by:
wget https://ftp.mozilla.org/pub/mozilla.org/firefox/candidates/38.0b2-candidates/build1/linux-x86_64/en-US/firefox-38.0b2.tar.bz2
mozinstall -d . firefox-38.0b2.tar.bz2
./venv/bin/firefox-ui-update --binary firefox/firefox --update-direct-only

I don't know how to handle this exception:
    "Connection timed out", status=errors.ErrorCodes.TIMEOUT)

With regards to the Marionette exception.
We probably need to wrap the key 'error' to inside of a dict. See output below. [1]

What I think it happened in here is that aus was temporarily unavailable, hence, failing to have an update.
From the gecko output, I think we received <parsererror/> since there was an empty XML:
https://dxr.mozilla.org/mozilla-central/source/toolkit/mozapps/update/tests/unit_aus_update/remoteUpdateXML.js#229

Attachment #8590302 - Flags: review?(cmanchester)
Attached file failed to apply
In this attachement we can see another update failure.
It's unclear to me why.
It seems that we failed the direct update test somewhere between "able to apply updates" and actually applying it.

It seems that we managed to download the partial update [1]
* setting state to: pending
* status: applied
* Notifying observers that the update was staged
* able to apply updates
and then out of nowhere:
* status: failed: 6, path: /tmp/tmpC6UoQw.binary-update-tests/updates/0/update.status

On another note, in this first test, we fail to use the partial update and immediately go for the complete update.
However, for the second test, it seems that we resume the partially complete update from the previous test (see "resuming download" message):
 *** AUS:SVC Downloader:onProgress - progress: 12375/45992037

Should we stop running the second test if the first fails?
Could we start from a clean state for the second test?

Have we seen this improving things? My understanding is that tearDown will always be run by the unittest library in case of a test failure/AssertionError, which will be very close to this behavior.
Attachment #8590302 - Flags: review?(cmanchester)
Regarding comment 3, "gecko.log" gets wiped out when we restart the browser, so the logs there might be somewhat misleading. Passing "--gecko-log -" to the runner will cause that output to go to stdout along with the test results, which may be helpful at least in the short term for debugging some of this.
I will use the gecko.log trick.

My expectations are the same as yours, however, I can actually see the difference with and without the patch.
In one we wait for 5/6 minutes and for the other one we fail fast.

These are the steps I used:
wget https://ftp.mozilla.org/pub/mozilla.org/firefox/candidates/38.0b2-candidates/build1/linux-x86_64/en-US/firefox-38.0b2.tar.bz2
mozinstall -d . firefox-38.0b2.tar.bz2
./venv/bin/firefox-ui-update --binary firefox/firefox --update-direct-only
Ok, I tried this locally and this indicates we're failing in tearDown (but succeeding as a side effect of tearDown if we call it twice). I should have thought of this before, but tearDown is attempting to do something in content scope when we're in a window (the about window) that has no content listener, so we hang. I believe bug 1141519 is meant to address this issue.

More precisely, this problem arises in some code run by the marionette harness between the test failure and tearDown (some callbacks are invoked that attempt to take a screenshot and get the source of the current web page). There's actually a passage in the update tests' own tearDown message that would prevent this problem by switching back to the main browser window, but we're too late by that point.
Let's keep this bug for this issue:
> Error: Unexpected node name, expected: updates, got: parsererror

If I see this issue again I will file it seperately:
> AUS:SVC readStatusFile - status: failed: 6, path: /tmp/tmpC6UoQw.binary-update-tests/updates/0/update.status
Summary: Failed to update → Error: Unexpected node name, expected: updates, got: parsererror
I am thinking that I could try closing and opening the about window a number of times until AUS returns the right value.
I would also like to take a screenshot to see what could be happening.

Bug 1141519 is the issue here, I'm fairly sure. I don't know the status of that bug but if it doesn't seem like it's landing anytime soon we can think up a workaround.
Any 503s you got are probably caused by https://bugzilla.mozilla.org/show_bug.cgi?id=1126825.

The code that triggers this bug is itself attempting to take a screenshot and get the source of the currently displayed web page. Once it's fixed we can pass "--log-html <path>" to the runner which will generate an html report that includes screenshots.

chmanchester: I looked at your last comments and my intention on this bug is to focus to the case when AUS is sporadically not available, hence, not giving an update to Firefox. See [1]

bhearsum: I see that update verify in general fails a lot and needs inspection. What should we do in here? Should we simply make firefox-ui-updates say that we could not determine the updates from AUS? Try few times?

Currently we raise an "AssertionError: False is not true"

I'm not entirely certain what this bug is about, but here's specific comments to your questions.

I'm not sure what you mean by this. We sometimes hit issues where update verify overwhelms AUS with requests, but in general update verify should be passing. If you're seeing a large amount of intermittent issues that retrying doesn't solve, there may be a larger issue at hand.

That is not a very helpful error message. In order to set the status os "FAILED" you'll need to make sure "FAIL" is in the output somewhere. The output from the update attempt (eg, the "AUS:SVC" messages) are really good to have too. It's almost impossible to debug failures without them.

I believe we could add rety logic to "check for updates" few times.

We always attach the gecko.log which contains the AUS values and I add "FAIL" to the output after firefox-ui-updates runs and returns a return code different than zero.

firefox-ui-updates raises that AssertionError but it doesn't know why there was no update. Inspecting the AUS messages can help us understand why there is no update available.
I thought more about this and if AUS starts misbehaving more than this will start failing and many locales would fail.
The only thing to make sense in here if we believe is necessary is to improve the output.
