Issues building new device #39

Closed singh763173 closed 6 years ago

singh763173 commented 6 years ago

Me again (this isn't related to any other issues)

I'm currently building a new Pi as i want to log temps elsewhere but getting the following issues when running sbt assembly

Standard procedure is to update with ‘git pull’ and try again. There’s a fair bit of development going on so you may have caught an unlucky build.

I’m working on a major version so keep and eye out. I’ll aim to package it slightly differently to avoid people having to rebuild (which is always annoying on a pi).

The other thing to try is ‘sbt clean’ before you try to build. You can also build in stages; run ‘sbt test:compile’ before you run ‘assembly’. The pi (zero especially) struggles a bit so it seems to help.

Ps the new version will have an export feature btw

singh763173 commented 6 years ago

Great news with regards to the export feature @tobyweston !

I just tried to update my current monitor and had the exact same issue - will try to run sbt clean and then re-run the assembly to see how that goes. Failing that, I may have to to revert to the previous commit (unless the next release isn't far off?)

Hope you had a great Christmas and Happy New Year in advance!

tobyweston commented 6 years ago

No ETA on the release but I could have a go at a preview release if I get the chance. Will let you know.

Cheers and HNY too! 🎄 🎉 🎈

tobyweston commented 6 years ago

I've been able to reproduce on a different machine, so it looks like its a genuine problem that wasn't showing up on my main machine. I'll report back with a fix.

tobyweston commented 6 years ago

I think this was caused by a duplicate file coming from SLF4J (when I introduced Log4J as the main logging library rather than SLF4J), removing that dependence seems to fix it but then there's no default binding causing:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I think the lesser of two evils is to change the merge strategy for assembly (https://github.com/sbt/sbt-assembly#merge-strategy). No idea to what though...

For reference, the dependencies are below.

10d00a8 fixes this (hopefully), have a go @singh763173 and report back!

singh763173 commented 6 years ago

@tobyweston completed successfully! looks like that did the trick - however I've now got a new problem - not sure if it's related.

sbt assembly completes successfully, but when running start.sh I'm not able to load the site. shall i raise a new issue?

singh763173 commented 6 years ago

strange behaviour - tempmonitor1 (the original one) now presents the WebUI but i get the following error

TypeError: n.data.map is not a function. (In 'n.data.map(function(e,n){return Object.assign({},e,{fill:!1,radius:0,spanGaps:!1,borderColor:t[n],backgroundColor:t[n]})})', 'n.data.map' is undefined)

tempmonitor2 (the new device) won't load the WebUI at all, even though sbt assembly completed successfully

tobyweston commented 6 years ago

The n.data thing is usually because the front end (UI) has started but can't speak to the backend for some reason. Is it just on the chart or on the temp values too? Screenshot?

For tempmonitor2: don't forget you have just one server and many clients. So say tempmonitor1 is the server and it's address is 10.0.1.10 and tempmonitor2 is your new client node at 10.0.1.20. You only start one as a server (with start-server.sh), the other you start as a client (with start-client.sh). The website is served from 10.0.1.10 in our example (the server), so after the second machine (10.0.1.20) has started up (check the logs that it started ok), you'd just go to the usual site (10.0.1.10:11900) and you'd see both sets of temperatures. Don't try and go to 10.0.1.20:11900 (the client) as there's no website there!

Not sure if that was obvious or not, apologies if you know all that already and thanks for bearing with me. It should be covered in the website docs. Give me a shout if that's not clear etc.

singh763173 commented 6 years ago

tempmonitor1 - only the graph - the value above is coming out fine - screen shot below

screen shot 2018-01-01 at 23 03 49

tempmonitor2 - update - found that sbt was permission with root which was causing some issues so chown and chgrp to pi - now when i go to run sbt assembly it throws a java error! unless i sudo sbt assembly which completes but still doesn't show the site completely understood with regards to client/server setup - i wanted to run them both as distinct servers, serving there own sensor starts individually and once it's proving to be working then run the server on 1 and client on 2. i assumed that having two servers wouldn't be an issue?

singh763173 commented 6 years ago

tempmonitor2 java error - incase it's useful

clearly a permission issue but not sure what files might be incorrectly permissioned

tobyweston commented 6 years ago

Running two servers will be a problem! The server broadcasts it's address so that clients can self discover where to send their data. If two servers are on the same network, they will probably fight for where the data is sent. Having said that, I think you might get away with it if you just have two servers and no clients (as the server's send data to themselves, circumventing the broadcast/self discover mechanism. I think! I'd never considered that scenario.

RE the stacktrace: it looks like you still have permission problems with something running as root. Maybe a folder is owned by root under code? If sbt once ran as root from that folder and it needed to create folders, they'd be owned by root. Perhaps sudo rm -rf target and try again?

singh763173 commented 6 years ago

deleted the target folder and tried again and same permission error

tobyweston commented 6 years ago

Yep, I mean under code. It's prob worth trying to clear down and start from fresh at this point if you can't find the folders.

There's a hidden folder that sbt uses under ~, something like .sbt and .ivy2. You could try deleting those too. Check under the root user's home too (not just pi). Try deleting code completly and redownloading etc? Remove and reinstall SBT?

tobyweston commented 6 years ago

You could try something like:

cd ~/code
find . -user root

to list things owned by root. Nothing should be there.

You could then try it from the pi user's home folder.

The syntax might be slightly off so test it first 😄

singh763173 commented 6 years ago

cheers Toby - deleting the code dir and cloning again appears to have done the trick and allowed me to compile. Not sure what happened there.

However - Still not presented with the webui.

I've noticed that i have a dodgy sensor and will have to solder a new one - is it safe to assume that the webui should still be presented, regardless of whether a sensor is present or not?

tobyweston commented 6 years ago

No, things wont startup without sensors. You should see something in the log though saying that.

btw, if you're interested in multiple sensors, I have some spare add-on boards available for free. http://temperature-machine.com/docs/add-on_board.html

singh763173 commented 6 years ago

I’d be absolutely interested! That would be simplify my setup massively!

If you have a 2 or 3, I’d be more than happy to reimburse you?

tobyweston commented 6 years ago

Can you share you email privately somehow (twitter DM?) and I'll arrange postage. Although I need to solder them up so might take me a week or two!

singh763173 commented 6 years ago

Wasn't sure if I found the right Toby Weston on twitter so dropped you a LinkedIn InMail instead! A little unorthodox... but it works i guess lol.

No worries with regards to time - take as long as you need!

Thank you!

Port clash. Both servers are trying to start up on port 11900 on the same machine.

It's probably because you're running the tests with the server still running on the machine.

singh763173 commented 6 years ago

Ah - that would make sense!

Still having issues with the graph not showing as per my screenshot above :(

tobyweston commented 6 years ago

The chart thing is intermittent, I've seen it once or twice. Its actually happening for me on one of the three graphs right now. I think I'll close this ticket and track the issue though #33 (although I wont get to it for a while as the work around seems to be give it time to regenerate and then refresh the page and I have no clue why at the moment!).
