From: wangbo wangbo.hfut@qq.com Date: Thu, 28 Jan 2016 20:39:25 +0800 Subject: LAVA uninstall and upgrade, build method from the source code Hi all,
I installed LAVA on Ubuntu 14.04 in our lab, but later we plan to upgrade the system to Ubuntu 15.10, so what should I do now?
I'm afraid the only long term option is to migrate to Debian Jessie, possibly using a VM, and then using jessie-backports. It is uncertain whether it will be possible to support LAVA on the upcoming Ubuntu Xenial 16.04LTS and support for Trusty has already been frozen. There have been problems upgrading from 14.04 - these issues have already been discussed on the lists.
https://lists.linaro.org/pipermail/lava-announce/2015-November/000003.html
The next upload of LAVA should be able to migrate into Ubuntu ahead of the cut off for the Xenial release but that is outside our control. It is also unknown whether it will be possible to maintain a system based on Xenial - the LAVA software team will be unable to maintain such support and users would need to be proactive in fixing problems that may arise.
Because I have already installed LAVA, so should I uninstall it firstly, and then use apt-get install to reinstall LAVA? But I can't find more information about this in the website, can you give me some advice, thanks very much.
https://staging.validation.linaro.org/static/docs/installing_on_debian.html#...
The main problems will be with the database, so building in any way will have the same difficulties. Trusty is, sadly, a dead end at the moment.
And, how to install LAVA from the source code?
Not supported - installation is only supported as Debian packages. LAVA is much more than a pip install / virtualenv can ever manage.
LAVA includes different parts, like lava-server, lava-dispatcher, lava-tool, etc. So which one should be installed firstly? By the way in the Git, for example "https://git.linaro.org/lava/lava-server.git/tree", there is no document about the install method. Now, I will modify some code to meet our demands in our lab, and then replace the corresponding file. We plan to manage the code with Git too. So if we know the install method from the source code, it will be better to build the code.
There is no documentation for installing from git because the installation method has moved to using packages. We abandoned the old install from git methods a long time ago due to interminable bugs and insolvable dilemmas.
During the migration to the new dispatcher, things are too complex to support more than Debian Jessie (and the next Debian release, Stretch). Once the migration is complete (in 2017), the advantages of the new design should also make it easier to support other operating systems. We are a long way from that at the moment.
Hi Neil,
Thanks very much to your quickly and warmly answer.
One more question:
LAVA copy all the test scripts defined in the YAML to the DUT at the specified directory, then the job will be executed on the DUT. And if I want to test one android device, but almost all the android images don't support python interpreter, so it's impossible to write case with python, in most cases we should use shell to run the test case. But sometimes we want to use Appium/Robotium to test the android image, and use LAVA to deploy the image, analyze and record the test results, so LAVA is unavailable in such conditions. Do you have any advice to integrate these tools in LAVA or will LAVA support such conditions in the future.
Best Regards.

The LAVA test shell scripts are POSIX shell. If a shell is not available, the test can be rewritten to use ADB commands, as the CTS tests do.
And if I want to test one android device, but almost all the android images don't support python interpreter,
LAVA does not run any python code on the DUT unless the test writer puts python commands into their test shell definition YAML. The python code only runs on the dispatcher and handles communications over the serial port (or using ADB).
so it's impossible to write case with python, in most cases we should use shell to run the test case. But sometimes we want to use Appium/Robotium to test the android image, and use LAVA to deploy the image, analyze and record the test results, so LAVA is unavailable in such conditions. Do you have any advice to integrate these tools in LAVA or will LAVA support such conditions in the future.
You'd need to use multinode (as with CTS) to install the test support binaries into a VM which then communicates with the device. That VM then reports results that are retrieved with LAVA.
Best Regards.
