ToDo for jenkins.debian.net =========================== :Author: Holger Levsen :Authorinitials: holger :EMail: holger@layer-acht.org :Status: working, in progress :lang: en :Doctype: article :Licence: GPLv2 == 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 * 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 === proper backup * 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' * postpone til we run on .debian.org? === 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 * do lvc for stretch too * mention stretch in README where appropriate === 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 slaves, probably/maybe also maintained by DSA (so we get them into their munin), but on which we can use sudo as we need it. (or maybe not dsa-maintained slaves, so that we can use sudo as we need, for the price of not being in DSAs munin.) ==== next steps for jenkins.d.o migration * weasel/h01ger: install jenkins.deb ** also create jenkins users in jenkins (KISS) * h01ger: get slaves: wishlist for starting: 3 slaves, 8 cores, 32gb ram, 150gb hd space if we dont need squid3 on them, 200gb if we do. ** install slaves - how (to automate)? * install jenkins-job-builder ** needs proper package * ... (to be planned, see below) * update DNS to point jenkins.d.o to jerea.d.o * ... (to be planned, see below) ==== unsorted notes for jenkins.d.o migration * 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 * sudoers.d/jenkins: ** not suitable for jenkins.d.o, thus we will run all tests on slaves, where DSA doesnt care what we do * upgrade to jessie, software used which is not in jessie / available as jenkins plugin: ** jenkins.deb *** DSA prefers if we could use jenkins from jessie-backports *** 2nd option: own repo, only contains jenkins.deb *** 3rd option: use upstreams repo ** jenkins-job-builder probably needs to be more properly packaged *** could be installed locally in jenkins home ** livescreenshot plugin (we use a patched version) *** jenkins maintaince probably is best done by jenkins users (as opposed to DSA) so that's up to us * munin monitoring of the slaves ** DSA munin configuration is auto generated by puppet, so the slaves should become .d.o hosts too, to be included * the existing jenkins.d.o host needs to be renamed to something else (thats "just work" to do but not a major obstacle) === 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. * install botch from jessie-backports once its available (and remove botch from the reproducible-unstable schroot) === 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 fil's package: http://ftp.hands.com/hands-deb/pool/main/j/jenkins-job-builder/jenkins-job-builder_1.2.0~git-0~1.gbp1ae299.dsc ** needs at least some of the stuff on fil's j.d.n.git/needs-jjb-1.2.0 branch to work with that ==== old jenkins-job-builder TODO, mostly (all?) obsolete 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 == lvc, work in progress, just started * 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 ---- == Improve existing tests === reproducible * higher prio: ** fix https://jenkins.debian.net/munin/debian.net/jenkins.debian.net/jenkins_builds.html which is broken since jessie upgrade ** exclude depwait from no_notes ** include depwait in graphs ** repo-comparison: check for binaries without source * lesser prio ** more graphs: *** graph average build duration by day *** graph packages in testing+unstable which need to be fixed ** 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...) ** new page: packages which are orphaned but have a reproducible usertagged patch ** 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) ** replace submit form by one without javascript (maybe with more url rewriting) ** html_indexes.py creates /index_notify.html three times, even though one is enough. ** when a package is automatically rescheduled because of the mirror was updated between the two tests, there will be three rbuild logs in one. thats confusing, the first one should be dropped. ** reproducible_blacklist.sh should delete rbuild logs and debbindiff output too ** adopt usertag script from pkg-apparmor to notify us about new usertagged bugs automatically ** fix apache ssl configuration as hinted by eg https://sslcheck.globalsign.com/de/sslcheck?host=jenkins.debian.net#46.16.73.183 ** create a symbol for pending bugs or use a different color to indicate them * 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 ** 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. *** aint that covered by reproducible_breakages.py already? no. * 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 * missing tests: ** variation in kernel ** variation in date ** prebuilder does (user) group variation like this: https://anonscm.debian.org/cgit/reproducible/misc.git/tree/prebuilder/pbuilderhooks/A02_user ** different cpu type: Opteron_G3 AMD Opteron 23xx (Gen 3 Class Opteron) is the most powerful one that's different to current Opteron_G4 ** 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 * a test VM using this build-slave design has been setup: ** 9 cores, 36gb ram, 80gb disk, 50gb /, 30gb /srv/kvm ** runs squid3 + kvm *** though squid is not configured yet ** kvm guest with different cpu, 32gb ram, 8 cores, 30gb / ** date changed in /etc/rc.local to today plus two days, one month and one year and hoping that the apt-signing key is still valid ** runs pbuilder inside the kvm guest * enable people to upload test packages, to be built in jenkins: ---- 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. 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 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. well, and everybody in debian-keyring from sid can uplood? :) that would be wonderful. ---- ==== 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 ==== reproducible openwrt * add credit for logo/artwork * build more archs (http://downloads.openwrt.org/chaos_calmer/15.05-rc1/ lists many to choose from) * build all packages? (set CONFIG_ALL=y and run 'make defconfig') ** just build some first... * file dbd bug about unable to inspect these .bin files * file dbd bug about crashing on certain squashfs files * explain status in plain english ==== reproducible netbsd * announce on their list * explain status in plain english ** MKREPRO is set to "yes" ==== reproducible fedora * use mock to create a fedora chroot to build in ** http://blog.packagecloud.io/eng/2015/05/11/building-rpm-packages-with-mock/ ** http://blog.packagecloud.io/eng/2015/04/20/working-with-source-rpms/ * start with building a single package * then build the full base system (100-500 packages) ==== reproducible freebsd * 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 ** adduser holger ** adduser jenkins (with bash as default shell) ** mkdir -p /srv/workspace/chroots/ ** mkdir -p /srv/reproducible-results ** chown -R jenkins:jenkins /srv/ ** ln -s /srv/ /usr/obj/srv ** we build freebsd 10.1 (=released) atm ** we build with sudo too *** change /usr/obj to be '~jenkins/obj' and build with WITH_INSTALL_AS_USER ? * first build world, later build ports (pkg info...) ==== reproducible... * openembedded.org! * Arch? Gentoo? ==== reproducible Debian armhf * use ftp.us.d.o on these machines * use http://10.0.0.15:8000/ as proxy * next: run pbuilder create jobs via remote job scheduling as described below * then: repo overview with binary packages * then: armhf scheduling (only for testing for now, introduce "arch-factor", eg. amd64=10 and armhf=3, to schedule less on some archs) * then: armhf building - run the job on jenkins.d.n and build1 on one host and build2 on another and then run debbindiff on jenkins.d.n… * then: run maintenance job via remote job scheduling * monitor their temperatures via munin, probably using munin-async via ssh… ==== remote jenkins job scheduling: ---- | h01ger: I have a slave configured, named buildbot.pixelminers. remote root is /home/jenkins/pseudo-hosts/buildbot.pixelminers.net and launch command is ssh localhost ~/pseudo-hosts/jenkins-tools/slaves/linux/start-slave.sh https://www.palfrader.org/volatile/2015-06-06-sP55pjoGcN8/screenshot.png https://gitweb.torproject.org/project/jenkins/tools.git/tree/slaves/linux - job: name: tor-ci-freebsd-amd64-master project-type: freestyle node: freebsd-amd64 builders: - shell: '~/jenkins-tools/slaves/other/build-wrapper' https://gitweb.torproject.org/project/jenkins/tools.git/tree/slaves/other/build-wrapper https://gitweb.torproject.org/project/jenkins/tools.git/tree/slaves/other/tor-ci-freebsd-amd64-master/build ---- === 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 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... === 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:
