Failure to connect diagnosis #231

billmeek · 2017-01-21T02:15:58Z

Comments (some nasty) of the app say that if the app
can't connect to the backend, there's no way to tell
what's wrong.

Would a solution be to check the individual parts of
the connection, e.g.

The tablet/phone has Wi-Fi turned on, not in airplane mode etc.
The backend can be reached, a la ping
Port 6544 is open
The API is working, Myth/GetHostName (I know this used to be done)

you mean pop a dialog with this information? Sure, sounds like a good idea.

I found this for the device itself:
https://developer.android.com/training/monitoring-device-state/connectivity-monitoring.html

There seems to be a ping in /system:
http://stackoverflow.com/questions/3905358/how-to-ping-external-ip-from-java-android

I use nmap -p 6544 backendName to see if the port is
even there (from the shell.)

I was think along the lines of a verbose description of any
failure, e.g.

Please turn on your Wi-Fi on this device.

or

Unable to connect to the backend, see if it's running and/or
check the backend logs. A simple test is to access the backend
Services API from a browser on this device. Try:

IP/hostFromSettings:6544/Myth/GetHostName

etc.

dmfrey · 2017-01-21T03:05:55Z

that's a good idea. let's outline the scenarios. Does each warrant a separate issue? I will probably have to come up with some more specific exceptions to capture these cases, so that we can trigger the specific messages in the UI.

The app is already doing network connectivity checks. Take a look at this code. It is being done in a few places and I should really clean that up so there is only ever a single instance of this code.

isThereInternetConnection()

Changes #231

dmfrey · 2017-01-21T15:37:27Z

@billmeek I am not sure a ping is needed, so long as we react to connection failures appropriately. The SnackBar can contain an OnClickHandler. So maybe we make the network connection SnackBar contain a Troubleshoot link that lets us call all of these on one screen. So we could list the result of the ping on one line, along with the test name and a red or green dot to show if it passed or not. We could call the /Myth/GetHostName and display it in the same way.

We could use this as a common place to display all these tests.

billmeek · 2017-01-21T18:56:29Z

Simple version of what follows:

is Wi-Fi on
is the backend's host up
is the Services API available

Found ICMP on this page, may help:
https://developer.android.com/reference/java/net/InetAddress.html#isReachable(int)
I like ICMP (ping) because it's just testing to see if the host is there. No port
required. It wouldn't need to be done all the time, just when troubleshooting
(e.g keep the existing isThereInternetConnection() and just drill down if
required.) I'm thinking isThereInternetConnection is testing the phone/tablet's
access to Wi-Fi.

Things like firewalls/port filtering may be in the way. The address
could appear in the SnackBar for all diagnostics. Ideally, the host
name if used in settings and always the IP, which could be IPv4 or 6.

I really like the idea of a Troubleshoot link.

Something like: if isThereInternetConnection() fails and Troubleshoot is
selected, then do the sReachable() followed by Myth/GetHostName to
verify that the Sevices API is fully available.

The troubleshootter is accessible from the navigation drawer, from the menu when viewing a media item details, or from a snackbar whenever a connection issue is reported. Changes #231

dmfrey · 2017-01-22T00:40:01Z

@billmeek checkout the branch feature/issue_231_connectivity_check and give it a look. You can access the troubleshooter from the navigation drawer, the overflow menu on a video or recording, or anytime a SnackBar shows a connection failure. I think it still needs a little cleanup, but I think it is in line with what you were thinking.

billmeek · 2017-01-22T01:12:39Z

Looking good! Recording right now, so only tested the 1st 2, plus I
mangled the hostname and that fails as expected.

Changes #231

dmfrey · 2017-01-22T23:54:52Z

@billmeek should we also add checks that we can parse recordings, upcoming recordings, encoders and videos?

billmeek · 2017-01-23T01:54:18Z

That could be good, not a connection problem, but a configuration one.

One user had: LANG="en_US.ISO-8859-1" rather than en_US.UTF-8
(actually, it was German) that caused a parser to fail.

There's another way to test LANG: http://mc0:6544/Myth/GetBackendInfo
once JSON parsing is known to be OK.

<BackendInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" serializerVersion="1.1">
<Build>
<Version>v29-pre-194-g2a1ccc0</Version>
<LibX264>true</LibX264>
<LibDNS_SD>true</LibDNS_SD>
</Build>
<Env>
<LANG>en_US.UTF-8</LANG>
<LCALL>en_US.UTF-8</LCALL>
<LCCTYPE>en_US.UTF-8</LCCTYPE>
<HOME>/home/mythtv</HOME>
<MYTHCONFDIR/>
</Env>
<Log>
<LogArgs>
--verbose general --logpath /var/log/mythtv --loglevel info --quiet
</LogArgs>
</Log>
</BackendInfo>

I should retest that in 3.0.1. (recording right now, again.)

MythTV uses UTF-8. It has previously been reported by users that they were having difficulting displaying the data and the result was their character encoding was not in UTF-8. This will help to diagnose this issue. Fixes #231

dmfrey · 2017-01-24T00:41:17Z

i should probably add a check in here for minimum mythtv version too. Thought?

Changes #231

billmeek · 2017-01-24T02:44:47Z

The version test makes sense to me. And it works with
v29-pre.

The text on the Troublesheeo Connection page that reads:
"Airplane Mode is on" should be off. I'll push that (the icon
is correct.)

dmfrey · 2017-01-24T03:11:09Z

Cool. Anything more with this. I was thinking about the tests to parse the json for recordings, upcoming, videos and encoders. We should be handling all the parsing errors with #68 so I don't think we will need to put that here. We should probably keep it to 1 screen.

billmeek · 2017-01-24T03:25:12Z

I like the existing screen, all the tests fit on a single
page of my Nexus 7.

Maybe all the text should just say what the test is
doing and let the icon reflect the state. I know that
if I enter the Airplane mode now, the text doesn't
change. Are you OK with letting the icons tell the
story?

dmfrey · 2017-01-24T03:29:39Z

Yes, that should be fine. Feel free to reword them. Keep them short enough to fit on one line.

dmfrey · 2017-01-24T17:33:35Z

just got the updates. gonna merge this into develop unless there are other outstanding requests

billmeek · 2017-01-24T17:55:12Z

I do have some changes to the text, but won't be able to get to
it 'til later today.

ok, let me know when you get them in and I will merge the PR

With troubleshooting, the app gets a fatal exception when it
tries to use GetBackendInfo for a version that doesn't have
the GetBackendInfo endpoint (< 0.28.)

curl -H Accept:"application/json" mc4:2744/Myth/GetBackendInfo
<?xml version="1.0" encoding="utf-8"?><detail><errorCode>401</errorCode><errorDescription>Invalid Action</errorDescription></detail>

Sent the above to my 0.27 backend (that's why the port above is 2744.)

Can you post the JSON for GetBackendInfo from v0.27? I'm guessing it's a mapping issue.

Unfortunately, it's an old MythTV issue. When the error fires, the response is
in XML, even though curl -H Accept:"application/json" mc4:2744/Myth/GetBackendInfo
was sent. If that endpoint existed in 0.27, then the response would have been in json.

billmeek · 2017-01-25T05:47:03Z

@dmfrey, just pushed some new text. All remain on a
single line on my tablet in both landscape and portrait
modes.

dmfrey · 2017-01-26T00:30:00Z

Reopening to address where /Myth/GetBackendInfo does not exist, but returns XML instead of JSON

…t have this url Fixes #231

billmeek · 2017-01-26T00:37:27Z

@dmfrey, I could open a new issue if you like. Rather than
this specific case, a generic case for XML coming back when
JSON is requested. I haven't found the MythTV ticket yet, but
do remember reading one. Out of my league and would only
be fixed in master since it could affect existing API clients in
my opinion.

…t have this url Fixes #231

dmfrey · 2017-01-26T00:40:18Z

Na, after looking at the stacktrace you posted, it looks like all I needed was another exception handler. Can you test it again with the latest commit?

billmeek · 2017-01-26T00:52:47Z

That looks like the fix. Now the Troubleshooter correctly fails
because the backend isn't 0.28 or later. The UTF-8 check
remains gray, because that test isn't reached, which is good.

All of the tests have been tested. The last one was LANG="en_US.ISO-8859-1"
in the backend and the UTF-8 test failed, as it should.

Closing.
