They should be separately maintained Not true. The master produces the configuration which is fed to the dispatcher - the two are very directly tied at the level of what devices can support and how that support is used by test jobs. Changes and fixes in the device-type templates will change how the dispatcher uses the code support to control the device. The two have always been maintained by the same team and in a tightly integrated manner. > , since > they represent (very) different things. Essentially, they do (very) > different tasks. They are, after all, apples and oranges. > The bulk of the expected work from here on is Device Integrations. Each new device integration typically involves changes to the dispatcher to support new deployment / boot methods as well as new templates for the device configuration. Combining the codebase allows those changes to be more easily verified because the output of the device configuration templates can be fed directly to the lava-dispatcher code changes in the dispatcher unit tests. Previously, this has resulted in static device configuration files in the dispatcher unit tests and that has caused problems. > > 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?! > Not true. the packages are built from a single source package. That does not mean that the binary packages need to be updated on the actual instances. Up until now, lava-server has always depended on the latest version of lava-dispatcher. That specific dependency is being removed as part of this change. Nevertheless, the principle remains that the lava-master and lava-slave should be updated together so that the device configuration is in line with the dispatcher support.

Merging the LAVA code source

by Neil Williams

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. All changes will be done in lava.git https://git.linaro.org/lava/lava.git/ The documentation will be updated over the next few days. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

2018.4 production release

by Neil Williams

The 2018.4 release has been uploaded to Debian unstable. It should also be possible to upload to Stretch-backports in about a week from now, depending on internal processes in Debian. The release is also available from the LAVA repositories - production-repo Dropping Python2 ================ 2018.4 is the first release exclusively using Python3. Upgrading from releases prior to 2018.2 will bring in a range of Python3 packages. After installation of 2018.4, a number of Python2 packages are available for removal, if administrators desire. See also: https://lists.linaro.org/pipermail/lava-announce/ 2018-April/000050.html lava-tool still uses Python2 - we are working on lavacli as a Python3 replacement. lavacli has also been updated to 0.8-1 in Debian. lava-server =========== f60a5328 callback: fix crash in python3 e627f8ec Allow skipping one unit test if kvm not enabled 0208402f job: make the link to the bottom more visible dd26e4fb Fix default BRANDING_BUG_URL b2cc847b Adjust bootm addresses for panda f25548b5 Make snow u-boot prompt more precise 6a209317 Misc beaglebone black fixes 1481ac98 Add note for bug in LXC templates on Stretch 4ed6a2f5 api: fix a crash when a test case is not unique 53c57de9 Fix crash when test case metadata is empty 99c32f4d Fix crash when action_metadata is None b286b6bd Fix missing import b708b038 Test user_command and flasher templates c316e516 Update more scripts to use Python3 4be0dd49 fix sphinx warning in docs 458f470e Improve "lava-server manage check" coverage 30efadeb LAVA-1274 fix javascript exception 31764a52 job: only update if failure_comment isn't empty 24fe81e6 LAVA-1276 -

Python3

by Neil Williams

The master branches of lava-server and lava-dispatcher have now moved to Python3 exclusively. This means that all developer builds will only support Python3 and that Debian Jessie is no longer supported for LAVA software. It is recommended to use the staging-repo as there are a lot of dependency changes to add Python3 dependencies on machines which have not used Python3 before. apt will make the job much easier than trying to install developer packages and then fixing the dependencies manually. Even if you have 2018.2 installed and have Python2 and Python3 support available, there are still some new dependencies to move the runtime support to Python3. The following NEW packages will be installed: gunicorn3 python3-dateutil python3-gunicorn The documentation has been updated: https://staging.validation.linaro.org/static/docs/v2/installing_on_debian.h… Once an instance has been upgraded, apt will typically warn about a range of Python2 packages which are no longer required. These can be removed using the command: $ sudo apt-get --purge autoremove Check the list of packages carefully! One example list could be: Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: python-django-auth-ldap* python-django-restricted-resource* python-django-tables2* python-ldap* python-lzma* python-markdown* python-netifaces* python-pyudev* python-simplejson* python-voluptuous* 0 upgraded, 0 newly installed, 10 to remove and 1 not upgraded. After this operation, 1,855 kB disk space will be freed. Do you want to continue? [Y/n] apt is cautious about listing packages for autoremoval, so you may well find Python2 packages still installed. This is normal. This starts a new round of functional testing in preparation for the next LAVA software release. That release will be Python3 only and it will not be built for Jessie. Debian uploads from here on will only be to unstable and stretch-backports. LAVA repositories will only carry updated packages for stretch-backports. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

Turning off builds for jessie-backports

by Neil Williams

See https://lists.linaro.org/pipermail/lava-announce/2018-January/000046.html The time has come to drop regular builds for jessie-backports. If you rely on these, you will have found that the builds of the master branch broke for jessie-backports some time ago (whilst the team were at a conference). So, in the absence of requests to fix the build and in the light of the existing plan to drop Jessie support in Q2 2018 (i.e. the next production release) there seems to be no reason to retain the build. This also means that building from the master branch for jessie is also broken - this is not going to be fixed. This opens the door for testing of lava-server using Python3 exclusively, dropping Python2 support. Depending on how that testing proceeds, the next production release could be Python3 only. Summary ======= * jessie-backports support in the staging-repo has ended * developer builds of the master branch no longer need to build on Jessie (and are currently broken) * there will be no further uploads of lava-server to jessie-backports or jessie-backports-sloppy in Debian. * support for Stretch continues unaffected * when the next production release is made, a backport to stretch-backports in Debian is likely to be uploaded. * There will be no further builds for Jessie for the production-repo or jessie-backports in Debian. * testing of full Python3 support can now begin -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

LAVA 2018.2 production release

by Neil Williams

Python3 ======= 2018.2 is built with Python2 and Python3 support but only Python2 remains is available for runtime (until Jessie support is removed). This results in the built packages for Debian unstable and stretch-backports now bringing in Python3 versions of the existing Python2 packages like python3-django. The unit tests are routinely run using Python2 and Python3. The packages available from the LAVA repositories reflect the same: jessie-backports 2018.2-1+jessie - Python2 only stretch-backports 2018.2-1+stretch - Python2 and Python3, using Python2 at runtime. Bootloader support changes ========================== 25859894 Better detect errors in the bootloader - this adds support to distinguish between a bootloader failure and a kernel failure to detect problems when the bootloader tries to start the kernel. This has an important effect on how some test jobs run - see Quiet Kernels below. The parallel change (7a2b3a68 Change the flow of bootloader commands so they are executed individually) supports detecting failures to download artifacts as distinct from failures to execute once downloaded. Bootloader action optimisations =============================== To support the better error detection, several bootloader actions have been optimised. This means that different actions may be used, changing the names you may be using for timeouts. e.g. https://staging.validation.linaro.org/scheduler/job/209814/definition#defli… The timeout name was u-boot-interrupt - now it is bootloader-interrupt. The UI shows you which actions have been assembled into the pipeline. e.g.: bootloader-interrupt: Wait for prompt Hit any key to stop autoboot (timeout 00:02:00) Quiet Kernels ============= The bootloader support changes wait for an indication that the bootloader has completed and that the kernel has started, by watching for a kernel_start_message. If your kernel is configured to be quiet, then each test job using that kernel *must* clear the kernel_start_message: context: kernel_start_message: '' In most cases, the test job should not use 'quiet' as this hides important debugging information from the kernel boot process. LXC mocker ========== lava-dispatcher now builds a second binary package which is intended to support the use of Docker without needing to change the test job submission which did not use Docker. e.g. submissions to LKFT use LXC and there are issues trying to use LXC inside Docker. To make it simpler to reproduce test jobs when debugging regressions, the lava-lxc-mocker can be installed in Docker instead of lxc. Commands which would then have been run in the LXC will instead be executed inside Docker directly. CAUTION: do not install lava-lxc-mocker *except* inside other containerisation like Docker. When using lava-lxc-mocker, create a dedicated Docker image which handles only one DUT so that tools like fastboot and adb which are constrained inside the LXC do not interfere with other test jobs and devices. If you have been using the developer build scripts and you are using 'sudo debi' then you will need to change to using 'sudo dpkg -i' and listing the lava-dispatcher package instead of the .changes file. Release cadence =============== Now that the roadmap to remove V1 is complete, the need for monthly releases has diminished. As part of a range of other plans aimed at making LAVA more flexible, the monthly release cadence has been dropped. We are looking at a range of options, including wider functional testing of the master branch, to support releases on a rough 3 month cadence but without the added pressure of expected release dates. This will become a lot easier once support for Jessie is dropped and the build matrix becomes simpler.

2018.1-1 Production release

by Neil Williams

Roadmap reminder ================ https://lists.linaro.org/pipermail/lava-announce/2017-September/000037.html Installing 2018.1 will apply the changes from 2017.12 and earlier to **permanently erase V1 test data** if this has not been done already. (i.e. if you skipped installing 2017.11 or 2017.12, remember that 2018.1 includes the changes of 2017.11 and 2017.12.) Removal of V1 test jobs ======================= A few provisos with this release - there are a lot more changes to the lava-server package than to the dispatcher because 2018.1 drops the old lava_scheduler_daemon app and moves all scheduling into lava-master. The new scheduler state machine involves some database migrations: Applying lava_scheduler_app.0032_add_state_health_to_testjob_and_device... OK Applying lava_scheduler_app.0033_remove_old_status_fields... OK Applying lava_scheduler_app.0034_worker_last_ping... OK If your instance has a lot of V1 test jobs still, the migration could timeout, so as the final part of the removal of V1, follow the guidance in the documentation to remove V1 test jobs, if you have not already. (By "a lot", we're thinking more than a few thousand.) https://validation.linaro.org/static/docs/v2/v1removal.html#removing-v1-fil… If you have millions of V1 test jobs (as validation.linaro.org had), you will need to stagger the removal of the V1 test jobs using the --older-than support. Talk to us if you have issues, there is an updated script which we used on validation.linaro.org but that would need to be locally cherry-picked from 2018.1 onto the system running 2017.12. The removal script can be interrupted with Ctrl-C and restarted if required. Depending on the performance of the host machine, it may take a long time to run the removal, up to several hours in some cases. Finally on the removal of V1 test jobs, the support removes not just the database object but also the log file directory, so your master should find a lot more usable fileystem space has appeared, once complete. In many cases, the log file directory can be missing for a V1 test job but the warning is just for information. The database object will have been removed. Removal of unwanted dependencies ================================ $ sudo apt-get --purge autoremove Do check the list of packages before proceeding. If there are packages which you need for local support, make sure those packages are marked as "manually installed" in apt by using apt-get install <package_name> (this doesn't reinstall an existing package, it simply marks it as not a candidate for autoremove). It is worth running autoremove after this release has been deployed, extra dependencies can still be a security problem and an admin burden. Stretch ======= 2018.1 *deprecates* Debian Jessie and moves the recommendation on to Debian Stretch as the supported OS for LAVA. https://lists.linaro.org/pipermail/lava-announce/2018-January/000046.html Note that when the instance is upgraded to Stretch, this will bring in a new major version of PostgresQL and your LAVA database will need to be *manually* migrated. Neither PostgresQL nor Debian will do this for you. https://validation.linaro.org/static/docs/v2/debian.html#migrating-postgres… When following this guide, remember that your versions will differ from the guide - typically for the upgrade to Stretch, you will be migrating from 9.4 to 9.6. Take care with the commands to ensure you drop and upgrade the correct cluster. Make sure you have a valid backup. The instance will need to be in a *maintenance window* for the migration to occur. Repositories ============ 2018.1 has been uploaded to stretch-backports and jessie-backports for the production-repo on images.validation.linaro.org and jessie-backports will continue to receive updates until we get closer to the end of security support for Jessie. See https://lists.linaro.org/pipermail/lava-announce/2018-January/000046.html lava-server =========== d87ccc73 Restore Health and TestJob Reports calculations 6aa325e0 Add a reason when updating device and worker health aaa1a959 Notifications: use email signature conventions 3f6770f4 Fix notifications and log the exception fbe57d5f Only use get_change_message on Django > 1.10 832edcf8 fix pep8 error ff1ef1c4 Disable high limits on ODROID-XU3 7ae61e90 Remove old sample job 4be662da LAVA-1206 -

Stretch and Python3

by Neil Williams

As announced in June 2017, Python2 is end of life. https://lists.linaro.org/pipermail/lava-announce/2017-June/000032.html However, the outline of the timeframe needs a few changes as Debian Jessie will lose security support around June this year and all LAVA instances will need to be running Stretch before that happens. It has proved to be impractical to support LAVA using Python3 on Debian Jessie and the completion of the migration has meant that lava-server is ready for Python3 ahead of schedule. Therefore, the pending 2018.1 release will **deprecate Jessie** and move the recommended installation of LAVA to Debian Stretch. The 2018.2 release of LAVA will add Python3 support to support developers and contributors using Python3. This means that the 2018.2 LAVA packages will contain python code in both the existing Python2 directories: /usr/lib/python2.7/dist-packages/ as well as the Python3 directories: /usr/lib/python3/dist-packages/ and will therefore bring in both Python2 dependencies *and* Python3 builds of those same dependencies. Installing 2018.2 will therefore bring in python3-django and a bunch of other Python3 packages, enough to run all the unit tests successfully on Debian Stretch using Python3, using stretch-backports. These are not yet used for runtime operations in LAVA, only for development and testing. A future release of LAVA will switch to using Python3 at runtime, dropping support for Python2 at the same time which will also drop support for Debian Jessie. This will happen *before* Jessie loses security support. As Stretch will be the minimum requirement for installation, this version would also move to requiring django 1.11 instead of 1.8 from Jessie. This creates a window for all LAVA instances to upgrade to Stretch using Python2 ahead of the separate move to Python3. To update the summary proposed in June 2017: Summary ======= June 17th, 2017 - Debian 9 Stretch release November 2017 - removal of V1 codebase January 2018 - migration of Cambridge lab to Debian Stretch instead of Jessie January 2018 - testing with django 1.11 LTS 2018.1 - testing with python3 2018.2 - add python3 support Q2 2018 - Release with python3 support, end of support for jessie-backports and drop python2.7 support. Move to minimum django version of 1.11 April 2019 - release of django 2.2LTS Actions ======= *ALL* LAVA instances should migrate to Debian Stretch support as soon as practical but certainly in the next three months. All development related to LAVA must support Python3 as of the release of 2018.1. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/
