== 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 soon, as some people actually care.

== General ToDo

* rename maintainance jobs into maintenance jobs
* replace amd64 in scripts with $HOSTARCH
* put kgb-client.conf in git and sed passwords from filesystem into it...
* move this setup to jenkins.d.o
** needs replacement of all chroot jobs with schroot
* build packages using jenkins-debian-glue and not my hacks
* move /srv/jenkins.debian.net-scm-sync.git somewhere public?
* *backup*:
** '/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)

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

* replace with bin/setsid.py workaround with setsid from the util-linux package from jessie
* etc/pbuilderrc: remove /run/shm bindmount once we are running jessie - this is a workaround for #700591
* 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.
* reproducible: let the scheduler use the xz-compressed file instead of the gzip one. This is because of missing lzma module in wheezy's python.

=== 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

* use jessie version plus my 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 my patches (eg add documentation) and send pull requests on github:
** publisher:logparse
** publisher:htmlpublisher
** svn:scm
** wrappers:live-screenshot

=== livescreenshot plugin

* publish forked livescreenshot plugin and send pull request for my bugfix

== lvc, work in progress, just started

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

* 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
----

== Improve existing tests

=== reproducible

* misc
** once cdbs 0.4.129 (#780592) reaches testing: reschedule these: rgrep -l "/usr/bin/make: invalid option" /var/lib/jenkins/userContent/rbuild/testing/
*** there are still builds with this failure, also in sid... ask ntyni for help
** find out why fonts-sil-gentium leaves not rbuild.log and no .buildinfo file and whether there are others like this
*** .buildinfo file and rbuild.log were created and exist on the filesystem
*** the bug is in strip_epoch() in _common.py which assume epochs are single digit...
** find debbindiff problems: rgrep -l "maybe there is still " /var/lib/jenkins/userContent/rbuild/
** reproducible: dont delete userContent/$pkg on build begin..
** move all content into /var/lib/userContent/reproducible/
** more graphs: graph average build duration by day
** turn job-cfg/g-i.yaml into .yaml.py
** meld bin/reproducible_setup_schroot.sh into bin/schroot-create.sh and alias the former to the latter
** "fork" etc/schroot/default into etc/schroot/reproducible
** include no js header in the css
** use one css for all, not two minimally different ones
** restore the "find packages which have been removed from sid" part of reproducible_maintainance.sh
** repo-comparison: check for binaries without source

* notes related
** new page with annoted packages without categorized issues
** issues pages for testing and experimental

* pkg sets related:
** new package set: kde/plasma
** here is a weekly updated list of the transitively build-essential source packages in Sid: http://bootstrap.debian.net/source/stats_min.json
*** curl http://bootstrap.debian.net/source/stats_min.json | sed -s "s#,#\n#g" |grep src:|cut -d ":" -f2|tr -d \" | sort -u
** for all pkg sets: only display FTBR+FTBFS and reproducible packages with notes by default, provide a way to show them all...
*** actually those links to packages are broken atm...
** replace bin/reproducible_installed_on_debian.org with a proper data provider from DSA

* db schema 2.0
** move "untested" field in stats table too? (as in csv output...)

* missing tests: variation in kernel and date
** http://www.bstern.org/libuname/ - add "-ldl" to the linker flags...
** lunar suggests to use qemu with -r and -cpu and -rtc flags
** https://wiki.debian.org/qemubuilder - part of cowdancer
	< Lunar^> I would rather say we do not do full uname and CPU variation that use an unreliable LD_PRELOAD
	< Lunar^> because as soon as the package unset or reset the variable it won't be there anymore
	       * | h01ger nods. its also ok to leave some variations for when we go "for real" (aka rebuilds in the field)
	<h01ger> | Lunar^: if that happens. if that doesnt we still get some more variations
	<h01ger> | so i'd say such an LD_PRELOAD would be useful, even though it wouldnt be complete
	<h01ger> | but we will find more problems "before going into the fields"
	       * | h01ger guesstimates that we would go from 300-600 builds per day to 100-200 with qemubuilder
	<h01ger> | but those qemubuilders would only get 4 or 8gb ram... maybe 6. and that will have a huge impact

* 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 
	<mapreri> jenkins tests.
	<h01ger> mapreri: please add the feature request to the todo. i'm thinking now that it maybe 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.
	<h01ger> well, and everybody in debian-keyring from sid can uplood? :)
	<mapreri> that would be wonderful.

=== qa.debian.org*

* turn udd-versionskew packages names into tracker.d.o links and provide version numbers in output too

=== d-i_manual*

* 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*

* 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 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
* g-i_presentation: use preseeding files on jenkins.d.n and not hands.com

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...

=== 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
