== About jenkins.debian.net

See link:https://jenkins.debian.net/userContent/about.html["about jenkins.debian.net"] for a general description of the setup. Below is the current TODO list, which is long and probably incomplete too. The links:https://jenkins.debian.net/userContent/contributing.html[the preferred form of contributions] are patches via pull requests.

== Fix user submitted bugs

* There are  link:https://bugs.debian.org/cgi-bin/pkgreport.cgi?tag=jenkins;users=qa.debian.org%40packages.debian.org["bugs filed against the pseudopackage 'qa.debian.org' with usertag 'jenkins'"] in the BTS which would be nice to be fixed rather sooner than later, as some people actually care.

== General ToDo

* replace amd64 in scripts with $HOSTARCH
* extend /etc/rc.local to do cleanup of lockfiles
* explain in README how to write jobs, eg which pathes are on tmpfs
* fix apache ssl configuration as hinted by eg https://sslcheck.globalsign.com/en/sslcheck?host=jenkins.debian.net#78.137.96.196
* run all bash scripts with set -u and set -o pipefail: http://redsymbol.net/articles/unofficial-bash-strict-mode/
* teach bin/chroot-*.sh how to nicely deal with network problems… (as both reproducible_build.sh and schroot-create.sh do)

=== TODO for testing stretch

Most jobs have been converted, a few are left to do:

* add g-i tests for stretch
* add stretch live-builds
* mention stretch in README where appropriate

=== To be done once jenkins.d.n runs jessie

* replace with bin/setsid.py workaround with setsid from the util-linux package from jessie
* bin/g-i-installation: use lvcreate without --virtualsize
* check if the sudo workaround in bin/g-i-installation is still needed: 'guestmount -o uid=$(id -u) -o gid=$(id -g)' would be nicer, but it doesnt work: as root, the files seem to belong to jenkins, but as jenkins they cannot be accessed.

=== To be done once jenkins.d.n runs stretch

* install botch from stretch and remove botch from the reproducible-unstable schroot
** botch now depends on a newer dose3, which depends on the ocaml from stretch. ocaml cannot be sensibly backported, so thats why this will have to wait for stretch

=== move this setup to jenkins.d.o

The plan is to run a jenkins.d.o host, which is maintained by DSA, but we are maintaining jenkins on it (so we can install any plugins we like etc). then we also setup several jenkins nodes, in the long term probably/maybe also maintained by DSA, on which we can use sudo as we need it.

==== next steps for jenkins.d.o migration

** the machine jerea.debian.org is setup, please go to http://jenkins.debian.org
** install jenkins.deb from jenkins-ci.org (DSA)
*** also create jenkins users in jenkins (we)
** create jenkins-job-builder backport from sid to jessie and install that (we + DSA)
** install all the plugins (we)
** add all the nodes as nodes to jenkins.d.o (we)
** disable job execution on jenkins.d.net(!) (we) 
** deploy this configuration on jenkins.d.o…(!) (we)
*** as we dont want irc nor mail notifications for this during the migration, we should disable those with an easily revertable commit before actual deployment
*** then rename jenkins.debian.net to profitbricks-build0-amd64 - and switch all the jobs which used to run on the master node on that node, which already has the right sudoers, usercontent/reproducible/ and reproducible.db
*** some authorized_keys will also need to be adopted for the change of IP address from jenkins.d.n to jenkins.d.o
*** redirect jenkins.debian.net to jenkins.debian.org - reproducible.debian.net will stay where it is.
* party!

===== leftover notes for jenkins.d.o migration

* livescreenshot plugin (we use a patched version) is ok:
** jenkins maintenance probably is best done by jenkins users (as opposed to DSA) so it's up to us what plugins we install
* chroot jobs should use real schroot sessions, and not just use schroot as poor chroot(8) replacement. some links:
** https://anonscm.debian.org/cgit/mirror/dsa-puppet.git/tree/modules/schroot
** https://anonscm.debian.org/cgit/mirror/dsa-puppet.git/tree/modules/porterbox/files/dd-schroot-cmd
** https://gitweb.torproject.org/project/jenkins/tools.git/tree/slaves/linux/build-wrapper

==== proper backup

* postponed til we run on .debian.org
* gpg encrypted to some keys
* run on alioth or paradis
* '/var/lib/jenkins/jobs' (the results - the configs are in .git)
* '/var/lib/munin'
* '/var/log'
* '/root/' (contains etckeeper.git)
* '/var/lib/jenkins/reproducible.db' (is backed up manually)
* '/srv/jenkins.debian.net-scm-sync.git' (is backed up manually)
* '/var/lib/jenkins/plugins/*.jpi' (can be derived from jdn-scm-sync.git)
* '/srv/jenkins.debian.net-scm-sync.git'
* '/etc/.git' and '/etc'

=== To be done once bugs are fixed

* link:https://bugs.debian.org/767260[#767260] workaround in bin/d-i_build.sh (console-setup doesn't support parallel build)
* link:https://bugs.debian.org/767032[#767032] manual fix in etc/munin/plugins/munin_stats
* link:https://bugs.debian.org/767100[#767100] work in progress in etc/munin/plugins/cpu
* link:https://bugs.debian.org/767018[#767018] work in progress in etc/munin/plugins/iostat_ios
* link:https://bugs.debian.org/774685[#774685] workaround in bin/reproducible_create_meta_pkg_sets.sh

=== jenkins-job-builder related

* investigate whether its possible nowadays to let it delete jobs which were removed.. nope. though it is possible to compare the list of all jobs which should be generated with those which are there and delete those which should not.

==== old jenkins-job-builder TODO, mostly (all?) obsolete/done thanks to fil's work:

* use jessie version plus h01ger's patches from kali
* change of syntax:
----
properties:
  - priority-sorter:
      priority: 150
----
* this seems to be helpful: http://en.wikipedia.org/wiki/YAML#References (pyyaml which jenkins-job-builder uses supports them)
* cleanup h01ger's patches (eg add documentation) and send pull requests on github:
** publisher:logparse
** publisher:htmlpublisher
** svn:scm upstreamed at https://review.openstack.org/#/c/192095/
** wrappers:live-screenshot upstreamed at https://review.openstack.org/#/c/191708/
** image-gallery: https://review.openstack.org/#/c/175747/ superseeds h01gers patch: https://review.openstack.org/#/c/191950/
** sidebar: upstreamed at https://review.openstack.org/#/c/191585/
** livescreenshot plugin:
*** publish forked livescreenshot plugin and send pull request for h01ger's bugfix
*** see ssh://git.debian.org/git/users/holger/livescreenshot-plugin.git and 0b407b70025 there

== Improve existing tests

=== reproducible builds

This is about Debian, below are more todo entries for other projects…

* make reproducible_build.sh rock solid again and get rid off "set -x # # to debug diffopscpe/schroot problems"
** fix: "DIFFOSCOPE='E: Failed to change to directory /tmp: Permission denied' - maybe by making sure the cause is gone… https://jenkins.debian.net/job/reproducible_builder_amd64_14/909/ is an example for that
*** make maintenance job detect and reschedule logs with: 'E: 10mount: error: Directory '.*' does not exist'
*** make maintenance job detect and reschedule logs with: '^Bus Error$'

* mention +398 days variation in variation table once this is declared stable
* reenable disorderfs setup, check that it *always* unmounts + cleans up nicely
* diffoscope needs to be run on the target arch... (or rather: run on a 64bit architecture for 64bit architectures and on 32bit for 32 bit archs), this should probably be doable with a simple i386 chroot on the host (so using qemu-static to run it on armhf should not be needed, probably.)
* on SIGTERM, also ssh to remote host and cleanup there! (via ssh &)

* higher prio:
** explain status in plain english on each coreboot/openwrt/netbsd/freebsd page, also on the Debian dashboard plus add an "executive summary about reproducible builds in the free software world"
*** get the content for "<h2>status of $1</h2>" from notes.git/friends.yaml or such
*** document in the non-debian pages, that we don't have a clear idea yet, how to record+reproduce the build environment and that this is essential for reproducible builds too.
** rewrite bin/schroot-create.sh from scratch, with little sudo.
*** analyse+summarize needs, git commit that, then writing the script will be trivial
*** use schroot tarballs (gzipped), moves are atomic then
** notes related:
*** #786396: classify issue by "toolchain" or "package" fix needed: show bugs which block a bug
*** new page with annoted packages without categorized issues (and probably without bugs as only note content too, else there are too many)
*** new page with packages that have notes with comments (which are often useful / contain solutions / low-hanging fruits for newcomers)
*** new page with notes that doesnt make sense: a.) packages which are reproducible but should not, packages that build but shouldn't, etc.
*** new page with packages which are reproducible on one arch and unreproducible on another arch (in the same suite, so unstable only atm)
*** new page with packages which ftbfs on one arch and build fine on another arch (in the same suite, so unstable only atm)
*** new page with packages which ftbfs in testing but build fine on sid
** new pages: r.d.n/$maintainer-email redirecting to r.d.n/maintainers/unstable/${maintainer-email}.html, showing the unreproducible packages for that address. and a sunny "yay, thank you"-summary for those with only reproducible packages.
** new page: packages which are orphaned but have a reproducible usertagged patch
** improve ftbfs page: list packages without bugs and notes first
** use static IPs (h01ger)
** mattia: .py scripts: UDD or any db connection errors should either be retried or cause an abort (not failure!) of the job
** save build-hosts in build_duration table (and change to saving the time of a single build, not both combined?)
** repo-comparison: check for binaries without source
** link howto on each coreboot/openwrt/netbsd/freebsd page
** pkg sets are still amd64 only atm… (and there is 404 link to the armhf page)
** bin/_html_indexes.py: bugs = get_bugs() # this variable should not be global, else merely importing _html_indexes always queries UDD
** new graph: looking at https://reproducible.debian.net/stats_bugs.png i wonder if it would be worthwhile to have https://reproducible.debian.net/stats_bugs_state.png but without the ftbfs tagged bugs… i'd hope that this graph is a.) new+interesting and b.) showing progress

* lesser prio
** check that build nodes have different amount of cores, so we dont need to run the 2nd build with NUM_CPU-1
** dashboard:
*** link https://reproducible.debian.net/unstable/amd64/stats_pkgs_to_fix.png and friends somewhere
*** number of cores used is wrong for amd64
** check that cleanup of old diffscope schroots on armhf+amd64 nodes works....
** check that diffoscope schroot have /usr/bin/ar installed, else fail the job
** check that /srv/workspace/pbuilder/ is cleaned up properly
** right align all numbers in table in the dashboard
** do final s#debbindiff#diffoscope#g and s#dbd#ds#g and rename .debbindiff.html+txt files as well as the dbd directories...
** pkg sets related:
*** fix essential set: currently it only has the ones explicitly marked Essential:yes; they and their dependencies make up the full "essential closure set" (sometimes also called pseudo-essential)
*** replace bin/reproducible_installed_on_debian.org with a proper data provider from DSA, eg https://anonscm.debian.org/cgit/mirror/debian.org.git/plain/debian/control
*** reproducible_create_meta_pkg_sets uses schroot created by dpkg_setup_schroot_jessie job (outside of reproducible job space...)
** "fork" etc/schroot/default into etc/schroot/reproducible
** move "untested" field in stats table too? (as in csv output...)
** a reproducible_log_grep_by_sql.(py|sh) would be nice, to only grep in packages with a certain status (build in the last X days)
** adopt usertag script from pkg-apparmor to notify us about new usertagged bugs automatically
** use reprepro and snapshot (reprepro gen-snapshot) on alioth to speed up our repo, maybe. maybe we'll just be in sid soon :-)
** database issues
*** stats_build table should have package ids, not just src+suite+arch as primary key
*** builder column of schedule table should not be used for state-handling of _remote_scheduler.py (by setting it to 'TBD')
** send notifications to maintainers when a note to their packages changes?
** blacklist script should tell if a package was already blacklisted. also proper options should be used...
** _maintenance.sh: delete the history pages once a page has been removed from all suites+archs
** new page showing arch all packages which are cross-reproducible, and those which are not
** (some!) build jobs should call _build.sh with a third host as param, which is tried as 2nd host if the real 2nd host is down

* missing tests:
** variation in kernel
** different cpu type (coming RSN)
** variation in date (coming RSN)
** prebuilder does (user) group variation like this: https://anonscm.debian.org/cgit/reproducible/misc.git/tree/prebuilder/pbuilderhooks/A02_user
** variation of $TERM and $COLUMN (and maybe $LINES), unset in the first run, set to "linux" and "77" (and maybe "42") in the 2nd run. maybe vary $SHELL too.
*** actually TERM is set to "linux" by default already, COLUMN is unset
** variation of filesystem being built on (work in progres, see 'higher prio' list above)
** variation of users shell (bash + zsh?)

* support for arbitrary (to be implemented) Debian-PPAs and external repos, by just giving a source URL
* enable people to upload test packages, to be built in jenkins:
----
  <mapreri> h01ger: another wild future request by me: allowing us to upload something and let jenkins test it. rationale: I sent (another) patch for debian-keyring, to fix a timestamp issue in debian control files (due to not_using_dh-builddeb), but there is also a umask issue. I don't want to bother me to setup the very same things jenkins tests locally (I already did too much in this regards, imho), but really people can't tests everything jenkins tests.
  <h01ger> maybe it should just be a jenkins job not integrated into the rp.d.n webui, but... maybe we find a nice way to do it
  <mapreri> h01ger: I'm instead thinking about a repo defining a reproducible-specific suite or something on that line, that integrates well with the current setup. but this is really something wild.

==== reproducible Debian armhf

* make systems send mail, use port 465

==== status of new remote build nodes for amd64

* new ones dont send mail

==== reproducible Debian installation

* see https://wiki.debian.org/ReproducibleInstalls
* add the test (something weekly or so)

==== reproducible coreboot

* add more variations: domain+hostname, uid+gid, USER, UTS namespace
* build the docs?
* also build with payloads. x86 use seabios as default, arm boards dont have a default. grub is another payload. and these: bayou  coreinfo  external  filo  libpayload  nvramcui - and:
** CONFIG_PAYLOAD_NONE=y
** CONFIG_PAYLOAD_ELF is not set
** CONFIG_PAYLOAD_LINUX is not set
** CONFIG_PAYLOAD_SEABIOS is not set
** CONFIG_PAYLOAD_FILO is not set
** CONFIG_PAYLOAD_GRUB2 is not set
** CONFIG_PAYLOAD_TIANOCORE is not set
* libreboot ships images, verify those?
* explain status in plain english
* use disorderfs for 2nd build?

==== reproducible OpenWrt

* add credit for logo/artwork
* build more archs (http://downloads.openwrt.org/chaos_calmer/15.05-rc1/ lists many to choose from)
* incorporate popular third-party ("external feeds") packages?
* explain status in plain english
* use disorderfs for 2nd build?

==== reproducible NetBSD

* explain status in plain english
** MKREPRO is set to "yes"
* use disorderfs for 2nd build?

==== reproducible FreeBSD

* run 2nd build 398 days in future
* useful improvements:
** investigate how to use tmpfs on freebsd and build there
** find a way to be informed about updates and keep it updated
** modify PATH, uid, gid and USER too and host+domainname as well. The VM is only used for this, so we could change the host+domainname temporaily between builds too.
** add freebsd vm as node to jenkins and run the script directly there, saves lot of ssh hassle
** run diffoscope nativly

* random notes, to be moved to README
** we build freebsd 10.1 (=released) atm
** we build with sudo too
*** rather not change /usr/obj to be '~jenkins/obj' and build with WITH_INSTALL_AS_USER. also not build in /usr/src. if so, we need to define some variable so we can do so.... but we need a stable path anyway, so whats the point.
*** maybe build as user in /usr/src...
* first build world, later build ports (pkg info...)

* document how the freebsd build VM was set up:
** base 10.1 install following https://www.urbas.eu/freebsd-10-and-profitbricks/
** modified files:
*** /etc/rc.conf
*** /etc/resolv.conf
*** /boot/loader.conf.local
** pkg install screen git vim sudo denyhosts munin-node
** adduser holger
** adduser jenkins (with bash as default shell)
** mkdir -p /srv/reproducible-results
** chown -R jenkins:jenkins /srv/

* system maintenance
** upgraded the VM to FreeBSD 10.2
*** done with: freebsd-update upgrade -r 10.2

==== reproducible Fedora

* call the script reproducible_rpms.sh as it can also build OpenSuSE packages
* create jessie schroot with mock and yum installed
** 'groupadd --system mock'
** 'usermod -a -G mock jenkins'
** see below for '/etc/yum/repos.d/'
* then use yumdownloader to download rpms: 'yumdownloader --source sudo'
** https://mirrors.fedoraproject.org/metalink?repo=fedora-23&arch=X86_64 has a list of repos
* then configure+use mock to build:
** 'sudo mock -r fedora-20-x86_64 --init'
** 'sudo mock -r fedora-20-x86_64 sudo-1.8.14p3-1.fc23.src.rpm'

==== reproducible Arch Linux

* job, to bootstrap an arch schroot needs to be made idempotent
** needs to download bootstrap.tar.gz sig and verify
** once this has been done, run it more often than once a year
* use regular maintenace job to update the arch schroot: 'schroot --directory /tmp -c source:jenkins-reproducible-arch -u root -- pacman -Syu --noconfirm'
* arch build.sh:
** introduce more variations: USER
** confirm the others are really working
** 'makepkg --skippgpcheck' should be replaced by 'makepkg' and 'echo "keyserver-options auto-key-retrieve" >> ~/.gnupg/gpg.conf'
*** this should make this obselete: 'schroot --directory /tmp -c source:jenkins-reproducible-arch -- grep  ^validpgpkeys= $PKG/PKGBUILD|cut -d "'" -f2|xargs schroot --directory /tmp -c source:jenkins-reproducible-arch -- gpg --recv-keys'
** on SIGTERM, also ssh to remote host and cleanup there! (via ssh &)
* create a working scheduler job
** test 'extra' too
** idea: reschedule reverse build depends too
* more random notes:
** rename arch scripts and jobs to archlinux
*** remember to adopt cleanup_schroot_sessions() in common_functions.sh when renaming the schroots
** use archlinux.css not the one from freebsd :)
*** use arch logo
* put results in a db
** graph results

==== reproducible...

* openembedded.org!
* Gentoo?

=== qa.debian.org*

* udd-versionskew: explain jobs in README
* udd-versionskew: also provide arch-relative version numbers in output too

=== d-i_manual*

* d-i_check_jobs.sh: check for removed manuals (but with existing jobs) missing
* svn:trunk/manual/po triggers the full build, should trigger language specific builds.
* svn:trunk/manual is all thats needed, not whole svn:trunk

=== d-i_build*

* d-i_check_jobs.sh: check for removed package (but with existing jobs) missing
* build packages using jenkins-debian-glue and not with the custom scripts used today?
* run scripts/digress/ ?
* bubulle wrote: "Another interesting target would be d-i builds *including non uploaded packages* (something like "d-i from git repositories" images). That would in some way require to create a quite specific image, with all udebs (while netboot only has udebs needed before one gets a working network setup).

=== chroot-installation_*

* use schroot for chroot-installation, stop using plain chroot everywhere
* add alternative tests with aptitude and possible apt
* split etc/schroot/default
* inform debian-devel@l.d.o or -qa@?
* warn about transitional packages installed (on non-upgrades only)
* install all the tasks "instead", thats rather easy nowadays as all task packages are called "task*".
** make sure this includes blends

=== g-i-installation_*

Development of these tests has stopped. In future the 'lvc*' tests (see below) should replace them.

These small changes are probably still worth doing anyway:

* g-i: replace '--' with '---' as param delimiter. see #776763 / 5df5b95908 in d-e-c
* download .isos once in central place
** /var/lib/jenkins/jobs/g-i-installation_*/workspace/*iso needs 53GB currently, it could be 30 less
* g-i_presentation: use preseeding files on jenkins.d.n and not hands.com
* turn job-cfg/g-i.yaml into .yaml.py

The following ideas should really only be implemented for the new 'lvc*' tests.... (but are kept here for now)

* pick LANG from predefined list at random - if last build was not successful or unstable fall back to English
** these jobs would not need to do an install, just booting them in rescue mode is probably enough
* for edu mainservers running as servers for workstations etc: "d-i partman-auto/choose_recipe select atomic" to be able to use smaller disk images
** same usecase:  -monitor none -nographic -serial stdio  

== Further ideas...

=== lvc, work in progress, just started

* upgrade lvc configuration to test stretch

* put this on debian isos too: config/chroot_local-includes/lib/live/config/9999-autotest

* add another (smaller) test: download+run torbrowser daily

* re-read the docs! 
** http://live.debian.net/manual/stable/html/live-manual.en.html#321

* generate feature files from templates? to cope with sub-products?
-> no. detect desktop type and set variables accordingly
-> simpler: pass an environment variable with the type

* get iso
* tables for looping through features: see tails/iuk.git/features/download_target_file/Download_Target_File.feature

* to debug cucumber: --verbose --backtrace --expand

* drop / remove
* can probably go: dhcp.rb firewall_leaks.rb dhcp.feature firewall_leaks.feature
* more occurances of "the computer boots Tails"
* @source (only keep product tests)

* disabled stuff in common_steps.rb
** #if @vm.execute("service tor status").success?

* "I set sudo password" not needed for debianlive nor debian(edu):
** #@screen.wait("TailsGreeterAdminPassword.png", 20)

* $misc_files_dir needed?
* def sort_isos_by_creation_date
  Dir.glob("#{Dir.pwd}/*.iso").sort_by {|f| tails_iso_creation_date(f)}
  -> useless for us, purpose is to automatically select the latest iso if none is given
* search case-in-sensitive for tails+tor+amnesia

* put in update_jdn.sh:
----
    addgroup tcpdump
    dpkg-statoverride --update --add root tcpdump 754 /usr/sbin/tcpdump
    setcap CAP_NET_RAW+eip /usr/sbin/tcpdump
    adduser $USER tcpdump
    adduser $USER libvirt
    adduser $USER libvirt-qemu
----

=== rebuild sid completly on demand

* nthykier wants to be able to rebuild all of sid to test how changes to eg lintian, debhelper, cdbs, gcc affect the archive:
* h01ger> | nthykier: so a.) rebuild everything from sid plus custom repo. b.) option to only rebuild a subset, like all rdepends or all packages build-depending on something
* h01ger> | and c.) only build once, not continously and d.) enable more cores+ram on demand to build faster

=== Test them all

* build packages from all team repos on alioth with jenkins-debian-glue on team request (eg, via a .txt file in a git.repo) for specific branches (which shall also be automated, eg. to be able to only have squeeze+sid branches build, but not all other branches.)

== Debian Packaging related

This setup should come as a Debian source package...

* /usr/sbin/jenkins.debian.net-setup needs to be written
* what update-j.d.n.sh does, needs to be put elsewhere...
* debian/copyright is incorrect about some licenses:
** the profitbricks+debian+jenkins logos
** the preseeding files
** ./feature/ is gpl3

// vim: set filetype=asciidoc:
