Hi everyone, As I have probably mentioned in previous emails, Im using the yocto project to generate some linux images that I want to test using lava as part of the continuous integration development. So far so good, i can submit the job description to lava using lava-tool and it will start the tests. I'm happy so far with all the results. Now my question is to ask you what would be the correct way do this procedure. Do you think it is reasonable to have a lava-tool submit-job followed by a waiting step using lava-tool job-status to report the final build result? or there is a nicer way to do this? Thanks a lot for your help in advance :) Best, Alfonso

[PATCH] bootloader: add ramdisk_raw option

by Kevin Hilman

By default, a uboot header is automatically added to the ramdisk image. For bootloaders without INITRD_ATAG support, the ramdisk needs to be passed on the command line and cannot have the uboot header added. To enable this feature, add a "ramdisk_raw" option that device files can set so that a uboot header is not added.

lava-dispatcher and lava-tool

by alfonso

Hello everyone, just a simple question. I might be wrong but I understand that submitting a job through lava-dispatch and lava-tool should lead to the same process. Now, with the dispacher you can already specify an specific target device encoded in yaml format. Does the lava-tool at some point reach a similar target configuration? does it generate it or it is stored somewhere? in the latter case, where is it stored? thanks in advance :) Best, Alfonso

matching results to requested tests

by Milosz Wasilewski

Hi, I'm trying to get the proper relationship between requested tests and results in LAVA v2. Here is example job: https://validation.linaro.org/scheduler/job/1109234 and results for this job: https://validation.linaro.org/results/1109234 How can I tell: - which result matches which test? - if there are multiple occurrences of the same test with different parameters, how to recognize the results? In LAVA v1 the matching was a very arduous process. One had to download the job definition, look for lava-test-shell actions, pull the test definition yaml sources and match yaml ID and to ID found in result bundle. How does this work in v2? milosz

Local lava-test-shell

by Milosz Wasilewski

Hi, Chase did an excellent job and put together a piece of code that allows us local execution of lava-test-shell. This means we can use our 'lava' test definitions on the boards that are not deployed in any LAB. There are 2 main reasons for doing that: - prototyping tests for LAVA - semi-automated execution of tests on targets that are not deployed in any LAB Major part of this code is taken directly from lava dispatcher. There are slight modifications but I would like to keep them to minimum or remove at all (if possible). So the question follows - is there a way to achieve the same goal with only LAVA code? One of the biggest problems was requirement for ACKing that lava-test-shell requires. This makes the tests 'interactive' which isn't best for semi-automated execution. This bit was removed and now we're able to use test shell locally in non-interactive mode. The README file describes the use cases we're covering. Any comments are welcome. Code can be found here: https://git.linaro.org/qa/lava-local-test.git milosz

Re: [Lava-users] LAVA setup for continuous integration validation of Android builds

There is no direct integration such as plugins which does this in LAVA. But you can submit jobs to LAVA via scripts, once the builds are ready in Jenkins. This is already done as part of many jenkin based CI loops used within Linaro and elsewhere. > Looking at the documentation, I came to know that Ubuntu support is > stopped. Would Debian Jessie be supported in future? Yes you are right Ubuntu is deprecated. Debian will be supported in future. We support Debian Jessie and Testing as of today.

No GUI Environment After Lava Installation

by Luís Matallui

Hi, I've just made a fresh Debian (Jessie) installation. Then, I've added jessie-backports and installed lava-server from there. Once the installation completed, I've rebooted and the GUI desktop environment doesn't come up. This happened twice already, so it's definitely the Lava installation that's breaking something there. Is this a known issue? Any suggestions? Regards, matallui

Boot Issue

by Albarran, Josue

Hi, I had a boot issue and it was because of using SPACE to stop the autoboot. A quick fix for this was to add a \" to a variable declaration such as "setenv dummy variable\"". Do you know of any other fix for this? It seems the default for lava is "Hit any key to stop autoboot" and just send a "b" to stop it. In my case, I had to change the device configuration file to look for "Press SPACE to abort autoboot in 2 seconds" and then send a " ". The device configuration looks as follows http://pastebin.ubuntu.com/18790420/. Now I have another issue where the job keeps going even though the image booted successfully. I want it to stop once it sees "am335x-evm login:". Is there a way to do this? I changed the master_str = am335x-evm login:. This is my complete log http://pastebin.ubuntu.com/18790288/.

Lava: advice for server installation

by Denis HUMEAU

Dear Lava team, We're deploying Lava V2. So far we've been working on old servers to prototype our installation. We're now almost ready to order our definitive PCs. We have assessed some key features for our Lava server. Still, we're not 100% sure on how powerful it should be. Is it possible for you to share the main characteristics of your current Lava servers (Number of cores, RAM, size of disk)? That would be helpful. Thanks and best regards, Denis Humeau

PDU and beaglebone black support in LAVA

by Albarran, Josue

Hi, I'm currently trying to configure a Switched Rack PDU to the lava instance. How do I know if the driver for my PDU APC AP7901 is supported in the framework? I got it connected both via serial and telnet. My /etc/lavapdu/lavapdu.conf file is attached. Also, when I restart the lavapdu-runner it fails with the error that is attached. As for the beaglebone black support, I have a device dictionary but where should I save it so lava can access it? I've seen that the pdu hostname is always similar to pdu05. How do I know my pdu's hostname? I appreciate the help, thanks. Regards, Josue Albarran

Looking for suggestions for dispatcher machines

by Sandeep Chawla

Hello, I have a lava setup and right now running two single instance servers. These are pretty high end servers are handling 4-5 Android devices over USB I need to expand that to multi node setup with maximum DUTs connected to one dispatcher. The target is only to have android DUTs so that implies a very stable USB hub and stack on the dispatcher machines. I used a couple of off the shelf desktops in the past and the USB stack could not handle more than 1 device at a time. Any suggestions for hardware that is proven to be solid for dispatchers. Thanks Sandeep

Upgrade from 2016.4 to 2016.6 breaks custom LAVA extension

by Konrad Scherer

Hello, For the 2016.4 release I had created a custom LAVA extension to add 2 commands and 2 xmlrpc methods. The extension mechanism was very convenient. All I had to do was install an egg on the system and restart the lava service. When I upgraded to 2016.6 the extension did not work due to commit b6fd045cc2b320ed34a6fefd713cd0574ed7b376 "Remove the need for extensions". I was not able to find a way to add my extension to INSTALLED_APPS and register the xmlrpc methods without modifying settings/common.py and urls.py. I looked through common.py and distro.py and could not find support in settings.conf for extensions. I also looked for a local_settings import which is referenced on the Internet as a common way to extend django, but did not find it. If there is a way to extend LAVA without modifying the LAVA python code, please let me know and I will be happy to send in a documentation patch. It would have been nice if functionality such as the extension mechanism, which is part of the external interface of LAVA, had gone through a deprecation cycle. A reworked demo app showing how the new extension mechanism works would have also been helpful. Thank you for your time. -- Konrad Scherer, MTS, Linux Products Group, Wind River

[LAVA v2] How to set up x86 devices

by Luís Matallui

Hi, For the last couple of days I’ve been trying to setup a device in our lab for deployment and installation of a Linux OS. However, I’ve came across a few issues and lots of questions and hopefully I can get some answers here. Considerations: 1. I’ve decided to give it a go with LAVA v2 and try using the pipeline model 2. I’m not testing any “boards”, so it’s hard to find a similar example 3. I am not deploying any Linaro images (not even debian based) 4. My team develops and supports a reference Linux OS, based on RHEL, so that means we have total control of our images, kickstarter scripts, etc. 5. We already have a PXE server in our network, which is where our servers (the targets in this context) get booted from by default 6. Once booted from PXE, we get a PXE menu, where we can either select an option, or press ESC and add a custom command (at this syslinux is running) 7. We have access to the serial console of every device via serial port server (telnet <ipaddr> <port>) 8. We have power control over every device via IPMI Issues: 1. I couldn’t find the documentation for how to add devices and device types to the server (which location to add the file, which format - yaml/conf) 2. In the above described environment, I suppose we would skip the deployment phase, since the devices already boot into syslinux from PXE (is this correct?). Either way, it would be nice to be able to run ‘ipmitool chassis booted pxe’ before rebooting the system. 3. Either way (via boot or deploy), how can I make sure to detect the PXE (syslinux) menu, send the ESC key, and send the command I need to trigger the kickstart installation? To sum-up, the Workflow I’m trying to achieve after having completed the whole setup sort of goes like this: 1. Reboot target device into PXE (the PXE itself will download and start syslinux here) 2. Wait for PXE menu (expect some sort of string) 3. Send ESC key (to get into the boot shell) 4. Send command (this will trigger our kickstarter script and the installation will take around 5 minutes). The images that are needed are fetched automatically from our sftp server. 5. Wait for boot prompt after system installation succeeds 6. Login using credentials (username, password) 7. Run whatever tests we need from here Any help here would be much appreciated. Thanks in advance! -- matallui

integration of 3rd party boards

Juno is not stable to allocate IP

Hi there, When I run LAVA hacking session on Juno but found sometimes Juno cannot be allocated IP properly: - I created multinode definition for Juno: https://validation.linaro.org/scheduler/job/845471.0: this definition is to launch kvm so I can run testing suits on it; https://validation.linaro.org/scheduler/job/845471.1: this definition is to launch "deploy_linaro_image" on Juno board; - After launched these two images, the kvm usually can work well and I can smoothly log in it with ssh; - But for juno board, it will have below log for ssh: 395.1 ./setup_session_oe: line 38: /etc/init.d/ssh: No such file or directory 395.2 <LAVA_SIGNAL_TESTCASE TEST_CASE_ID=sshd-restart RESULT=fail> 395.3 sshd re-start failed 395.4 Target's Gateway: 10.0.0.1 395.5 ip: RTNETLINK answers: Network is unreachable 395.6 395.7 395.8 ********************************************************************************************* 395.9 Please connect to: ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no root@ (juno-07) 395.10 ********************************************************************************************* 395.11 So finally I cannot get the info for Juno's IP and cannot log in it with ssh. It's not everytime I can reproduce this failure, so sometimes it's lucky so I can get a correct IP. - As a workaroud, I found if I create two saperated definitions for Juno and kvm independently, then Juno's IP issue can be resolved: https://validation.linaro.org/scheduler/job/845552 https://validation.linaro.org/scheduler/job/845561 So could you help give suggestions for this? Thanks, Leo Yan

lava testing

by pradeepkumar

Hi, I have made a test setup with LAVA to run some test cases on my AM335X based platform. I want to execute some simple test cases like testing the status of "ifconfig eth0" command. I don't want to deploy any image and my goal is to execute only this test directly(target is booted with root file system mounted).I have the below job submitted to the lava worker. ethernet.yaml contains the shell script which actually performs the ifconfig test. ============================================================================================= { "actions": [ { "command": "dummy_deploy", "parameters": { "target_type": "oe" } }, { "command": "lava_test_shell", "parameters": { "testdef_repos": [ { "testdef": "/root/lava_tests/yaml/ethernet.yaml" } ], "timeout": 60 } }, { "command": "submit_results_on_host", "parameters": { "server": "http://10.24.252.13:81/RPC2/", "stream": "/anonymous/lavaserver/" } } ], "device_type": "ELIN", "health_check": false, "job_name": "elin-ethernet-test", "logging_level": "DEBUG", "timeout": 60 } ======================================================================================================= Lava dispatcher is able to connect to the target and start the job. But finally I am getting a timeout. Please find the attached log for details. I can see that after connecting with the target the dispatcher is checking/finding some information related to the file system, and looks like it is getting timed out there. How can I avoid this and make the dispatcher to directly perform the test on the target platform? Any help any help would be appreciated. Best Regards, Pradeepkumar Soman

Request for new XML RPC endpoints to add remote control for devices

by Quentin Schulz

Hi all, We are using LAVA to run jobs from KernelCI which is a test automation system used to test latest versions of the kernel (upstream, next, stable, ...). Our main goal is to put in our lab a maximum of boards which are not yet in KernelCI to provide boot reports for these boards. However, for some of these, we own a single copy while we definitely need to work on them to add new features or improve them. What we could do (and what we are currently doing), is to manually put a board in maintenance mode, take it physically outside of the lab, work on it and put it back in the lab when we have finished working on it. This is not really efficient and during the time the board is physically outside of the lab, not a single job (from KernelCI or ours) can run. We would like to create a tool to be able to remotely control our boards while they still are physically in the lab. We need to be able to do everything we could do if the board would be on our desk. This means getting the serial connection, powering on or off the board and sending files (kernel, DTB, initramfs, ...) to it. For the latter, we just have to copy the files in the directory used by the TFTP server of LAVA master node. I would like to know if it is possible to add an endpoint in the API to power on or off a given board? Is it possible to get the serial connection over the API? To put a board virtually outside of the lab, we need to put it into maintenance mode in LAVA. As of yet, this is only possible from the browser, right? It would be great if we could add two endpoints to the API: one for putting a board offline and one for putting a board online, so we can remotely manage from our program whether a board is in the lab. We may have few people working on the same board. Therefore, we need a way to ensure only one person is able to use this board at a certain time. I've seen the "created_by" attribute in the DeviceStateTransition[1] which could help us to find who last put the board virtually outside of the lab and thus denying access to other users. However, we do not have a way to get this information today via the API. Is it possible to add an endpoint to get the status of a given device (like in 'all_devices'[2] but for one device) and the associated user responsible of the last device state transition? I can help with patches if you agree to add these endpoints to the API. Thanks, Quentin [1] https://github.com/Linaro/lava-server/blob/release/lava_scheduler_app/model… [2] https://github.com/Linaro/lava-server/blob/release/lava_scheduler_app/api.p…

Re: [Lava-users] [RFC] utils (http_proxy): fix url string search in url list

by Matt Hart

The Cambridge LAVA Lab has a transparent squid proxy which saves having to configure each dispatcher and device to use it. Outgoing HTTP traffic from the lab has no choice as it is intercepted at the internet gateway. We did this because even after configuring the dispatcher, and devices, it's almost impossible to make all test shell tasks use the proxy. LAVA sets a shell environment inside a job but many of the clients in the various different types of job simply ignore it. Chasing every test writer was not feasible as the lab usage is so large, but might be ok in a smaller lab with tighter control of the jobs. We don't proxy HTTPS requests because that's becomes very complicated with faking certificates etc >>Marc Titinger <mtitinger at baylibre.com> writes: >> >> I had to make this change to get squid3 going with our LAVA 1.0 machine. >> I thought this could be useful.

About the cursor movement in the device config file.

by Elaine Wu (wuyanjun)

hi, all, I am using the new uefi, it use the cursor movement and the Enter to enter the entry. So I use the config file to write it, but I found it can not work well. the config is below. boot_cmds_ramdisk_sata = expect "Move Highlight", sendline "\033[B", sendline "\033[B", sendcontrol "M", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendcontrol "M", expect "D02", sendline "provision {SERVER_IP} -u htsat -p hello8943217 -f Image_D02 -a 10000", expect "succ" , sendline "norwfmem 100000 100000 1f00000", expect "OK", sendline "provision {SERVER_IP} -u htsat -p hello8943217 -f hip05-d02.dtb -a 100000", expect "succ", sendline "spiwfmem 100000 300000 100000", expect "OK", expect "OK", sendline "exit", expect "Select Language", sendline "\033[B", sendline "\033[B", sendcontrol "M", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendline "\033[B", sendcontrol "M" After I read the source code of LAVA. I found it use the pexpect.spawn to interact with the terminal, So I directly writte a python file to directly use spawn to interact with the terminal, and it can work well . The source code is below. import sys from pexpect import spawn child = spawn("board_connect 2") # this is similar with minicom logfile = "/tmp/test_for_terminal.log" fd = open(logfile, 'a+') child.logfile = fd child.expect("to stop automatical booting", timeout=120) child.sendline("b") child.expect("Move Highlight") ## boot from sata child.sendline("\033[B") child.sendline("\033[B") child.sendcontrol("M") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendcontrol("M") child.expect("D02") child.sendline("provision 192.168.6.100 -u htsat -p hello8943217 -f Image_D02 -a 10000") child.expect("succ") child.sendline("norwfmem 100000 100000 1f00000") child.expect("OK") child.sendline("provision 192.168.6.100 -u htsat -p hello8943217 -f hip05-d02.dtb -a 100000") child.expect("succ") child.sendline("spiwfmem 100000 300000 100000") child.expect("OK") child.expect("OK") #child.interact() child.sendline("exit") child.expect("Select Language") child.sendline("\033[B") child.sendline("\033[B") child.sendcontrol("M") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendline("\033[B") child.sendcontrol("M") child.interact() So I don't know why in LAVA it can not work. Also I have realized a function named /sendcursor /similar with the sendcontrol in the lava_dispatcher package especially in the /usr/lib/python2.7/dist-package/lava_dispatcher/utils.py, and it call the pexpect.spawn.sendline to send contents to the child process. But it still have the same phenomenon with using sendline(namely won't select the entry in the uefi menu). Does this problem is caused by the dashboard showing? The attached files are the log files when I use the python file to execute the interaction and the one when LAVA execute it. Thanks for your help. Elaine Hisilicon turing software and architecture

Configuration file for new devices

by Quentin Schulz

Hi, We are building a LAVA lab which will be soon integrated to KernelCI. We want to add most of our boards to LAVA that's why we created configuration files for the old dispatcher (the one used by KernelCI at this moment) for all device types we own. I would like to know if you were interested in getting those configuration files to put them in your git repository (we are using some from: https://github.com/Linaro/lava-dispatcher/tree/release/lava_dispatcher/defa… If yes, what is your naming convention? I've seen sama53d for the SAMA5D3 Xplained for example. This is the list of boards currently added to our lab: Board name Current configuration file's name NextThingCo.

lava job strucked when execute the config file.

by Wu Yanjun (Elaine)

hi, I have two questions to ask: 1. I am using the lava to boot the D02 board, it can successfully execute before. But it failed after I update the uefi and rewrite the config file. But when I execute the config file manually, it succeed booting the board. And I can figure out what is wrong. The version of LAVA I used is 2015.9.post1, and I use LAVA v1. From the figure, we can see it is strucked when booting the kernel. then The log file of the lava job, the log of boot manually and the config file has been attached. 2. The uefi is used need to control by cursor movement, so I need to send KEY-DOWN in the d02.conf file. But when I use 'sendline "\033[A"' or ‘sendline "\16[A"', I found it can not work in the LAVA. So I want to know if we have any method to realize it? Thank you very much. -- Best Wishes wuyanjun (Elaine) Hisilicon Turing Software and Architecture

the board uefi use dialog to boot, how can I configuare the lava device-type config file.

by Elaine Wu (wuyanjun)

hi, all, The uefi the board used has upgraded, so that the configuration of it can not be used in the current environment. Because now the uefi use the dialog to show the menu. As I know, the expect and sendline in the lava XXX.conf can not work well in this situation. Does you know how to config the XXX.conf to support this kind of uefi? The menu of the uefi is below. and Thank you very much. Elaine (wuyanjun) Hisilicon, Turing Architecture and Software

adding per-action comment or brief description or meta-data into the bundle

by Marc Titinger

Hi Neil and all, how do I add per-action comments or meta data so that I can parse them from the result bundle: the following for instance will pass the schema validation, but the result bundle will degenerate into keeping only the last "comment" metadata entry, while I'd like a per-action metadata entry. { "command": "lava_command_run", "metadata": { "comment": "comment1" }, "parameters": { "commands": [ "uname -a" ] } }, { "command": "lava_command_run", "metadata": { "comment": "comment2" }, "parameters": { "commands": [ "ls -al" ] } }, The result bundle will contain the same metadata for each lava-command: "attributes": { "comment": "comment2", <=== same value "image.type": "kernel-ci", .... snip ... "logging_level": "DEBUG", "device.tree": "omap4-panda-es.dtb" }, "test_id": "lava-command" IOW, how do I assign a brief description to an action ? Thanks and regards, Marc.

Missing apache config file

by Felsch Marco

Dear LAVA-Team, I have set up two new LAVA instances (master, worker) based on the production release 2016.02. The installation worked fine but I can't switch the apache site. I followed the instructions on: https://validation.linaro.org/static/docs/installing_on_debian.html#install… Then I searched for the lava-server.conf file on my system, but didn't find it. It looks like it isn't installed. I also tried to add it to add it manually, but it didn't worked. i.A.

For all lava-tool users

by Neil Williams

If you are running lava-tool on Debian unstable (sid) or testing (stretch), the new version of python-keyring (8.4.1-1) will break lava-tool at versions lower than 0.14-2 as it has moved a previously supported component into a separate package which did not previously exist. Sadly, the lava-tool maintainers were not made aware of this change in functionality in advance - lava-tool simply stopped working in unstable. lava-tool 0.14-2 has been uploaded with the only change being a dependency on python-keyrings.alt which is the new package which provides the functionality formerly available as part of python-keyring itself. python-keyrings.alt already exists in Debian testing and can be safely installed ahead of the upgrade of python-keyring, so users may wish to install python-keyrings.alt now in order to maintain functionality. Version 8.4 of python-keyring will migrate into Debian testing before version 0.14-2 of lava-tool can migrate, so users of testing may have a short window where lava-tool fails in Debian testing if python-keyrings.alt is not installed in advance. Ubuntu users may also be affected as python-keyring is a "main" package, so may possibly update in Xenial Xerus - however as lava-tool is a "universe" package, it may not be possible to upgrade Xenial to 0.14-2 of lava-tool. Users are advised to manually install python-keyrings.alt to maintain functionality. lava-tool users running Jessie are not affected (but are advised to upgrade to 0.14-1~bpo8+1 from jessie-backports for other updates, new functionality and bug fixes). -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

[RFC v2] lava_command: add host-side enter/exit hooks to control measurement tool

by Marc Titinger

This is used to generate measurements by interacting with devices that are not reachable as a node, and avoid target-specific support. Each device.conf file can define a host command or script used when entering a lava_command_run and leaving a lava_command_run, In the style of the PDU power cycling commands. host_hook_enter_command = <enter_hook> (command line to pass to host) host_hook_exit_command = <exit_hook> Hooks calling abi: ENTRER: arg0 = <enter_hook> arg1 = "output-file-fullpath" & EXIT: arg0 = <exit_hook> arg1 = "output-file-fullpath" & The MO is close to lava_test_shell: the LAVA_SIGNAL_TESTCASE search pattern will be applied to the output of the exit hook and if a measurement is found, a test_case will be added to the bundle stream of the job. Any file found in the logdir will be attached, starting with stdout.log. If a {output-file-fullpath}.minetype is found, its content is used as 'mime_type' for the attached file (as with lava_shell_test) example, see Job http://lava.baylibre.com:10080/dashboard/streams/anonymous/lab-health/bundl… as an example of unit-test power statistics record and display as test_cases.

Re: [Lava-users] Forward of moderated message

by Neil Williams

> From: wangbo <wangbo.hfut(a)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.

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. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

using shell-hooks to record stuff on host

by Marc Titinger

Hi Neil et al. I'd like to have the host record power measurements during a job, or during a unit-test. browsing the lava manual, I came across the shell-hooks which seem to enable what I want to do. Suppose I want to call a script "capture-start.sh" at the top of the job, and "capture-stop.sh" at the end, is this the proper way to do stuff: In the job json: ------------------- ``` { "command": "lava_test_shell", "parameters": { "testdef_repos": [ { "git-repo": "https://github.com.... /lava-test-definitions.git", "testdef": "capture-start.yaml" } ], "timeout": 1800 } }, .... dispatcher actions of interest .... { "command": "lava_test_shell", "parameters": { "testdef_repos": [ { "git-repo": "https://github.com.... /lava-test-definitions.git", "testdef": "capture-stop.yaml" } ], "timeout": 1800 } }, ``` In the yaml, do I need to override all the handlers ? If I don't need end_case or postprocess_test_result do I need to fill them, and point to a "nop.sh" script "? I assume that I need to provide at lest one step to be done on the target, even if I am only interested in the host-side commands, would the following yaml make sense: ``` metadata: format: Lava-Test Test Definition 1.0 name: power-capture-start run: steps: - lava-test-case pass-test --shell echo starting power measurements handler: handler-name: shell-hooks params: device_config_vars: DEVICE_TYPE: device_type handlers: start_testcase: capture-start-start-hook.sh end_testcase: nop.sh postprocess_test_result: nop.sh ``` Thanks and Regards, Marc.

u-boot version of panda master image

by Marc Titinger

Hi all, I have a basic practical question: I'm trying to reset a panda-es board with a suitable master image for lava to use with the default device-types confs, namely with: lava-dispatcher/device-types/panda-es.conf:bootloader_prompt = U-Boot so I wrote panda-master-20150303.img.tgz (linaro master-images) to the sdcard I'm using. I'd expect u-boot.bin on the boot partition to being compatible with the expected lava prompt and u-boot command set ('bootz' supported for instance), but I keep having an incompatible config of u-boot ("Panda" as a prompt, bootz not supported, etc...), what am I missing? Thanks and Regards, Marc.

help with initial config of a beaglebone-black while setting up a local dispatcher

by Marc Titinger

Hi All, I'm setting up a local LAVA scheduler+dispatcher (standalone). I'm able to posts jobs, but I think I'm missing an initial configuration for some actions to complete, namely action deploy_linaro_image the eMMC flash content of my BBB-RevB6 is pretty standard (debian-7.9 of 2015-11-03, 2gb image). Based on the log, the dispatcher expects the default "testboot" and "testrootfs" partitions with offset 2, I assuime this means that those partitions must be manually created the first time with index 3 and 4 in order for this to work. I would appreciate some hints, to avoid unnecessary test-and-try, what would be the expected partitionning for BBB with LAVA ? Thanks in advance, best regards, Marc.

Issues with Django OpenID Authentication

by Neil Williams

Please let us know if you are using OpenID authentication with LAVA. Newer versions of django will make it impossible to support django-openid-auth in Debian unstable and testing. The version of django-openid-auth in Jessie can continue to be used, so we would like to know how many users want to continue with this support. OpenID as a protocol has been dying for some time and Linaro has moved over to LDAP, which is fine if LDAP is already available. The time pressure for this change is coming from the schedule to get the latest django and the latest lava packages into Ubuntu Xenial 16.04LTS which means that support needs to be implemented in the 2015.12 or 2016.1 LAVA releases. This is why this is quickly following the trusty change. We have been aware of the issues with django-openid-auth for some time, it was only when we had completed the move of the Cambridge lab to LDAP that changes involving django-openid-auth could be considered. If you are using OpenID authentication (e.g. using Launchpad or Google OpenID), please let us know. If you would like to see some other forms of authentication supported, also let us know. We can investigate Python Social Auth (http://psa.matiasaguirre.net/), if there is interest. If we don't hear from users who want django-openid-auth support for use on Debian Jessie, we will drop django-openid-auth support from all lava builds. This will leave LDAP and local Django accounts in 2015.12. If anyone has experience of other django authentication modules, also let us know. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

Freezing support for LAVA on Ubuntu Trusty 14.04LTS

by Neil Williams

See also: https://lists.linaro.org/pipermail/lava-announce/2015-November/000002.html which was also sent to these lists (except linaro-dev). So far, nobody has come forward as a Trusty user. The only Trusty instance of which we are aware is already due to migrate to Debian Jessie. The LAVA software team are now applying updates which will freeze LAVA software support for Ubuntu Trusty at 2015.9 for lava-dispatcher and 2015.9.post1 for lava-server due to the complexities of supporting both django1.6 and the current django1.7 in Jessie and django1.8, possibly django1.9 by the time Debian Stretch is released. The last packages for Ubuntu Trusty 14.04LTS will be: lava-server 2015.9.post1 lava-dispatcher 2015.9 Once these changes are applied, the Debian packaging used to build future versions of LAVA packages will prevent builds against django1.6 and prevent installation if django1.6 is found, in order to prevent database corruption. This means that Trusty users will not be able to use the results of the dispatcher refactoring. Ubuntu Xenial Xerus - which is planned to be the 16.04LTS in April 2016 - is expected to pick up LAVA software releases from Debian up until the 2016.1 release (possibly 2016.2) and is also expected to be using django1.8. The next Debian stable release (Stretch), for which no date has yet been set, may use django1.9. Initial attempts at migrating a test instance from Trusty to django1.7 did not go well and the migration from Trusty to Xenial cannot be supported by the LAVA software team - the recommendation is to go directly from 2015.9 on Trusty to the same version available for Debian Jessie but there will still be work to be done to prepare and implement the migration which will be instance-dependent. Documentation is being added to assist with this migration but there will remain risks of data loss which will need to be managed for each instance. It is imperative that anyone using Trusty has an up to date backup of the postgresql database dump before considering any migration. If the existing data is to be dropped, a new install on Debian Jessie is recommended. It is not possible for the LAVA software team to support all versions of django from 1.6 to 1.9 - particular problems are known when going from django1.6 to django1.7 as the methods to migrate the lava-server database changed fundamentally in django1.7. Notes are being added to the documentation on the trusty branch based on 2015.9 to be released within lava-server 2015.9.post1 and to the documentation in the master branch (which will go into 2015.12). All future builds of LAVA software will now be made and uploaded only to Debian and releases.linaro.org. So far, nobody has come forward who is willing to maintain packaging for LAVA software on any distribution other than Debian. As the refactoring proceeds, we expect that it will become easier to package LAVA for other distributions but the migration to the refactoring must be complete first. Everyone interested in or using LAVA is encouraged to subscribe to the lava-announce mailing list which is low volume and only used for substantial changes like this. https://lists.linaro.org/mailman/listinfo/lava-announce See also https://validation.linaro.org/static/docs/support.html -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

Calling all Trusty users of LAVA

by Neil Williams

This is a call to *all* users of LAVA on Trusty - please let us know who you are, what you're needs are and whether you are able to migrate to Debian Jessie instead of going from Trusty 14.04LTS to Xenial Xerus 16.04LTS. If you are using LAVA on any release of Ubuntu older than Trusty, the only advice from the LAVA team is to immediately migrate to Debian Jessie. If you are using LAVA on Wily Werewolf or Vivid Vervet, you should also consider testing the migration to Xenial and comparing with a migration to Debian Jessie, as below. LAVA is looking at a fix for the 2015.9 release but Django1.9 is in beta release already. There are issues with django1.8 which are in development. Currently, we are proposing that this update will be applied to 2015.9 and made into a frozen release. The master branch of LAVA will continue to develop and will need to use more features only available in Django1.7 and later. Documentation relating to installing Trusty would then be deprecated and removed in subsequent releases from the master branch. Equally, future database migrations on the master branch would no longer provide south support, using the django migration support provided by django1.7 and later. So these releases would not be built for Trusty - leaving only the frozen branch. Due to the complexity of supporting django1.6, it is unlikely that updates will be available for the frozen branch once this happens.. The changes in the lava-server due to the ongoing refactoring will mean that users of Trusty will be unable to migrate to pipeline support until the server has also been migrated to Xenial 16.04LTS. In addition to this, there is concern that migrating from Trusty and django1.6 all the way to django1.8 or possibly django1.9 in Ubuntu Xenial 16.04LTS is going to be problematic and the LAVA team will be unable to assist in most cases. The alternative is for someone with a reasonably complex lab running Ubuntu to take up a role as tester of the frozen branch *and* responsibility for patches which can maintain trusty support and migration to Xenial 16.04LTS. The problem then will be that it will be a very large transition when 16.04LTS actually becomes available - only for the same lag to start all over again. I'm unsure when Xenial will close the window for migrations from Debian into Xenial - I expect that the 2015.12 release of LAVA will migrate, I expect that 2016.1 will migrate too but I cannot be sure about 2016.2 or 2016.3. That migration is completely outside the control of the LAVA software team. https://launchpad.net/ubuntu/xenial/+source/lava-server Everyone considering staying on Ubuntu is advised to try a migration to Xenial *now* - in a VM, with and without a recent backup of your database and logs. Xenial currently has 2015.11. Also compare with a migration to Debian Jessie by dumping and reimporting the database. In each case, ensure that the permissions on /var/lib/lava-server and sub-directories are retained from the original. Please talk to us and test out what you are going to do. https://validation.linaro.org/static/docs/support.html -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

A few notes which subscribers should follow and recommend to others: 0: Wherever possible, use a pastebin for log output and include a link to the paste in your post. 1: Paste from the complete log, not the summary, so that you get the complete lines. 2: Include in this paste or another paste, the job definition 3: If your job uses URLs which are not visible to the rest of the list, include a rough outline of how those were built and what versions of tools were used. Subscribers are invited to help each other.
