Re: [Lava-users] [Lava-announce] Merging the LAVA code source

by Zoran S

> lava-server and lava-dispatcher have been merged into a single source repository - lava If you ask me, this is the (very) questionable decision. Indeed!? lava-server is the front-end manager of the whole Lava test environment, while lava-dispatcher is the back-end. Connected/splitted by ZMQ protocol. And... They should be separately maintained, since they represent (very) different things. Essentially, they do (very) different tasks. They are, after all, apples and oranges. In other words, if you update/buy advanced/more expensive apples, you also force testers to update for nuthin'/buy for the loss the same oranges, they had before?! Is it the wise decision??? Two cents worth lamenting/analysis, Zoran _______ On Thu, Apr 19, 2018 at 3:41 PM, Neil Williams <neil.williams(a)linaro.org> wrote: > This is for particular note for developers as it changes the way that > reviews happen. > > If you've noticed a few reviews being abandoned, this is why. > > lava-server and lava-dispatcher have been merged into a single source > repository - lava > > lava-coordinator will follow in time, to ease the update of lava-coordinator > to Python3. > > This will, in future, allow easier testing of device integrations by > allowing the lava_scheduler_app unit tests to be linked to the > lava_dispatcher unit tests and have a single review which adds both sides of > the device support. > > There will be a lot of testing, as normal, so staging will be moving to > packages built from the new source repository tree. > > The old lava-server.git and lava-dispatcher,git repositories will become > read-only and will get no further code changes.

LAVA device tags

by Conrad Djedjebi

Good morning everyone, I am looking for few guidelines while using device tags in LAVA. The following link on LAVA Documentation's webpage explains how to use tags: https://staging.validation.linaro.org/static/docs/v2/developing-tests.html *However, once the tags are created, how to assign them to specific devices ?* I created tags in the scheduler app, but I am not finding any option in the web page of LAVA to assign a specific tag to a specific device. I saw many devices using tags in LAVA LAB. I hope the engineers who set up those devices can give me advice. If anyone else has some ideas about the trick around setting up those tags, I would appreciate. regards,

Notify callback section causing health check to fail

by Robert Marshall

I had a notification section as follows notify: criteria: status: complete verbosity: verbose callback: url: http://localhost:8080/scheduler/job/{ID} method: POST token: mytoken content-type: json dataset: results recipients: - to: method: email email: address(a)site.org largely copying that from other examples as experiments. I've been seeing as I changed other parts of the health check that it was failing - timing out when booting the kernel. If I remove the callback section so notify: criteria: status: complete verbosity: verbose recipients: - to: method: email email: address(a)site.org then the health check consistently works. Is there some side effect going on here - or is my callback section causing the error, that localhost url should be ok. I'd expect it to always fail if there's a problem with it? Robert

Installing LAVA-2018.2

by ankit gupta

Hi All, I have Debian 9(stretch) installed on my system and I want to install LAVA 2018.2 (server as well as the dispatcher), I used "*deb https://images.validation.linaro.org/production-repo <https://images.validation.linaro.org/production-repo> stretch-backports main*" repository for this. But it only installing LAVA 2017.7 version and it's only showing LAVA-server version 2018.2 in the upgrade but not LAVA-dispatcher-2018.2. Please suggest do I need to use some different repository for LAVA-dispatcher-2018.2? Thanks, Ankit

Re: [Lava-users] fastboot in LXC LAVA

by Karsten Tausche

Hi Conrad, one of the devices in our setup is a nexus4, which will be most useful for reference. It has this device dictionary jinja: {% extends 'nexus4.jinja2' %} {% set adb_serial_number = 'someserialnumber' %} {% set fastboot_serial_number = 'someserialnumber' %} {% set device_info = [{'board_id': 'someserialnumber'}] %} {% set static_info = [{'board_id': 'someserialnumber'}] %} Maybe the fastboot_serial_number is the critical part here? I think some parts in the device type definition expected this value to be defined. The device type is the nexus4 definition that is included in LAVA. It runs with the health check from the LAVA repos [1], expect that Debian Sid is replaced by Stretch for LXC (seems that the scripts are not compatible with the current Sid). Adding the following test demonstrates some fastboot commands that work here: - test: namespace: tlxc timeout: minutes: 5 definitions: - from: inline name: some-fastboot-commands path: inline/some-fastboot-commands.yaml repository: metadata: format: Lava-Test Test Definition 1.0 name: some-fastboot-commands description: "some-fastboot-commands" run: steps: - adb start-server || true - adb wait-for-device - adb reboot bootloader - sleep 60 - fastboot devices -l - fastboot reboot - sleep 10 - adb wait-for-device The LAVA master+dispatcher are running on Debian Buster. LAVA version is 2018.2-1 (Debian packages).

[RFC] meta-lava

by Remi Duraffort

Hello, in order to validate that lava-server and lava-dispatcher are not regressing from one version to another, we added a lot of unit tests that are run every time a commit is pushed under review on https://review.linaro.org/ Before each release, we also run integrations tests on real hardware. However, we don't have access to most of the hardware currently supported by LAVA. Which mean that we cannot fully tests that LAVA is not regressing. For this reason, we created a project called meta-lava (currently available at https://framagit.org/ivoire/meta-lava) When run, meta-lava will: 1/ build a docker image for lava-server and lava-dispatcher * install lava-server and lava-dispatcher Debian packages from the production repo * pull the sources from git and overwrite installed sources 2/ start the containers in a specific network (meta-lava-net) 3/ wait for lava-slave to connect to the master 4/ launch a bunch of tests 5/ compare the results against the expected results In order to run the tests (as the meta-lava slave is *not* connected to any real hardware), we use a program called DummySys ( https://framagit.org/ivoire/DummySys) that will: * print the exact lines that lava is expecting * expect the exact inputs that lava is supposed to send This allow to test that lava will always behave exactly the same, for a given type of board, from one release to another. We can also simulate hardware failures, kernel crashes, ...and check that LAVA will continue to report the error correctly. meta-lava is currently running health-check for 24 device types (see https://framagit.org/ivoire/meta-lava/tree/master/tests/health-checks) and also checking for some common errors (like auto-login failures) or use cases (doing a GET on a given url when a job is finished). However without some help from the lava community we won't be able to add every boards that you care about nor all your specific use cases. So if you are interested, please raise your hand and contact me. Thanks -- Rémi Duraffort LAVA Team Linaro

fastboot in LXC LAVA

by Conrad Djedjebi

Good morning everyone, I would like to have your advices on the following subject : attaching a fastboot device in LXC container during a LAVA job. I am currently running jobs on a device through adb without issues. LAVA is adding udev rules which make it possible for the LXC container to successfully attach the target. However, when the device turns into fastboot mode, a "fastboot devices" command in the LXC returns nothing. In fastboot mode, the USB link of the device is added whereas the device is not listed among the fastboot devices. In the host, a "fastboot devices" command returns the id of the device. Did anyone here already faced that situation in the past? regards,

multinode+lxc/fastboot: reboot_to_fastboot, multinode device count

by Karsten Tausche

Hi Folks, I'm experimenting with Multinode for distributing tests across multiple Android DUTs (for using the CTS shards option at some point). The problem now is that the devices are rebooted to fastboot after the test although reboot_to_fastboot: false is specified in the test parameters. Apparently this parameter is not passed over from the multinode job to the LxcProtocol. Any idea on how to fix this? I attached a basic test shell definition that demonstrates the problem. A side question here: If I set the count of the worker role to something larger than 1, one of the job instance will stop incompletely with "error_msg: Invalid job data: ["Missing protocol 'lava-lxc'"] <http://localhost/results/testcase/817>", and the other two time out at "Multinode wait/sync". Am I missing something here or is this a limitation of the multinode/lxc protocol combination? Thank you, Karsten
