Sorry, but this was only a notification of a decision already taken and
implemented by the development team. The change itself was not and is not
up for discussion on this list.

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.

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.

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. See compatibility settings in the documentation.

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.

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.

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.

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

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.

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

http://www.linux.codehelp.co.uk/
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.

http://www.linux.codehelp.co.uk/
This release has been uploaded to Debian and the LAVA repositories. The
release fixes a security issue with private test jobs. 2017.12 added
support for the REST API to access test job definitions. This change caused
a problem where test jobs in which visibility had been set to personal or
group were correctly displayed in job tables but the job definitions were
accessible via direct URLs.
This hotfix resolves this problem in lava-server.
There was also a problem with the command line support for adding workers,
this has also been fixed in this hotfix release.
