Perl Continous Integration

Continuous Integration Tools in Perl Michael Peters Plus Three, LP YAPC::NA 10 Pittsburgh, PA

What is CI? ●Build and test all the time ●As soon as you can ●As loud as you can ●On as many platforms as you need ●On as many different configurations as you need

What is CI? ●Home grown (bash + email) ●CruiseControl ●Buildbot ●Tinderbox ●CABIE ●Smolder Hudson, TeamCity, Continuum, Cerberus, ControlTier, ● OpenMake Mojo, lots of others

Take a drink

CruiseControl ●http://cruisecontrol.sourceforge.net/ ●Java based ●Very well known, "industry standard" ●Lots of plugins for lots of things ● SCM ● Notification ● Build management (make, Ant, Maven, rake) ● Lots more

CruiseControl ●Web UI ● View old builds/tests ● See what CruiseControl is doing right now ● Is it checking out code? ● Is it building? ●Build Loop Daemon ● Separate process to do the heavy lifting

CruiseControl

CruiseControl Limitations and Complaints ● Not Perl (Java) ● Run loop is on a single machine ● They are working on distributed ● Format is not a standard ● Yes it's XML, but... ● Whatever JUnit spits out

CruiseControl Limitations and Complaints ● Not Perl (Java) ● Run loop is on a single machine ● They are working on distributed ● Format is not a standard ● Yes it's XML, but... ● Whatever JUnit spits out ● All Java and all XML

Take a drink

Buildbot ●http://buildbot.net/trac ●Python based ●Designed to be distributed ● master/slave architecture ● nice for OSS projects and volunteers ●Tracks some metrics over time ● warnings ● link checks ● compile time ● etc

Buildbot ●Lots of notification channels ● Email ● IRC bot (real time insults) ● GTk app ●Lots of built-in support for CSMs ● CVS, svn, perforce, Bonsai, git, Mercurial, Bazaar, ●Web UI ●CLI

Buildbot

Buildbot Limitations and Complaints ● Not Perl (Python) ● Sometimes too heavy ● Ugggggly ● It's complicated ● Configuration is all Python ● Format is not standard ● Whatever your test spits out and returns ● Developer's can't customize notifications for themselves ● No detailed breakdown of test failures

Take a drink

Tinderbox ●http://www.mozilla.org/projects/tinderbox ●Perl based ●Mozilla Project ● currently being rewritten ● used for Firefox, Thunderbird, etc ● Integrates with Bugzilla ● Only supports CVS ●Add comments to build runs ●Currently being rewritten ● Seems to use Buildbot underneath

Tinderbox

Tinderbox Limitations and Complaints ● No packages, no releases (grab from CVS) ● Not much support ● from Mozilla ● nor the Perl community ● Just does CVS ● Developers can't customize their notifications ● Kind of ugly

Tinderbox Limitations and Complaints ● Format is not standard append 3: object count 10 = 10 OK array count 13 = 13 OK 0: 3=3 (0x84f9540) c: 4 OK 1: 0=0 (0x84f9510) c: 1 OK 2: 1=1 (0x84f9520) c: 1 OK 3: 2=2 (0x84f9530) c: 1 OK 4: 3=3 (0x84f9540) c: 4 OK 5: 4=4 (0x84f9550) c: 1 OK 6: 3=3 (0x84f9540) c: 4 OK 7: 5=5 (0x84f9560) c: 1 OK 8: 6=6 (0x84f9570) c: 1 OK 9: 7=7 (0x84f9580) c: 1 OK 10: 8=8 (0x84f9590) c: 1 OK 11: 9=9 (0x84f95e8) c: 1 OK 12: 3=3 (0x84f9540) c: 4 OK

Take a drink

CABIE ●http://cabie.tigris.org/ ●Perl based ●Web UI and CLI tools ●Job daemon ● scheduled build jobs ● job priority ● job triggers ●Data stored in MySQL ●Email notification

CABIE Limitations and Complaints ● No installer ● Format is not standard ● Whatever text your build/test spit out and return ● It's ugly too ● No community support

Take a drink

Smolder ●http://github.com/mpeters/smolder/tree/master ●Perl based ●Web UI ●Some CLI tools ●CPAN installable ●Public and Private ● understands projects ● understands developers ●Being used for Parrot VM project

Smolder ●View detailed reports about exactly what failed ● Ajax/on-demand ● Much easier to find what went wrong ●All reports are submitted TAP Archives ●All data stored in SQLite ●Notification channels ● Email ● Atom ●Tags ●Trend reporting

Smolder

Smolder Limitations and Complaints ● Fair number of dependecies ● 44 deps ● 132 deps of deps of deps... ● HTTP::Server::Simple isn't very reliable ● Hard coded notification options (only email and Atom) ● No plugins for extra features ● No integration with other systems

Smolder Limitations and Complaints ● No integrated build system ● simple bash script + cron ● SmokeRunner::Multi ● Module::Build::Smolder ● No notifications of build failures

Take a drink

My Dream Date ●Smolder and Buildbot sitting in a tree... ●Separate, but integrated build loop and reporting ●Build status and detailed test reporting ●Optionally distributed for multiple platforms and parallel builds ●Standard formats ● TAP ● Something for the build notifications

My Dream Date Pluggable architecture ● ● Notifications (email, twitter, building alarm system) ● SCM support ● Common build systems (make, Makefile.PL, Build.PL, Ant, Maven, rake) ●Expose the TAP metadata for plugins to use ● Link to bug reports ● Link to source code or specs ● visual diffs ●Installable via CPAN ●Packagable for distros
