WHAT WE HAVE ACCOMPLISHEDMonday, 21 May 12 11

DATA/MODEL SEPARATION • Lookup of class parameters separate from the manifest • You can assume it is there! • No manifest changes needed • Uses Hiera as the back-endMonday, 21 May 12 12

RUBY 1.9.3 ...is finally a first class citizen. This is part of 3.0.0 Fully supported. All bugs fixed. (Probably)Monday, 21 May 12 13

PUPPET MODULE TOOL • Project Geordi La Forge • PMT ships with 3.0.0 • Making it more awesome! • Bufﬁng up publishing • Enhance the forgeMonday, 21 May 12 14

VARIABLE SCOPE FIXED • No more dynamic scope • Killed deprecation warnings! • Local, then inherited... • ...then node, then global.Monday, 21 May 12 15

GIVE BACK MEMORY • Daemon mode used to grow and grow... • Now, we return memory to the OS • Part of our performance improvement strategyMonday, 21 May 12 16

ENC VS ENVIRONMENTS • You could set the client environment from the ENC • The client would ignore you (sometimes) • Now it doesn’t • Bug ﬁx, not feature • Still great!Monday, 21 May 12 17

PLUGIN SYNC • This worked unevenly • Failures on ﬁrst run • Oddities about what can by synced and used successfully • Now, uniform and standardMonday, 21 May 12 18

DSL POLISH • Add “unless” to the language • Allow keywords as resource parameters and properties • Fixed some parser bugs (like ‘-’ in variable names) • More of this coming...Monday, 21 May 12 19

HIDDEN CHANGES • Lots of bugs ﬁxed • Code cleanup • Performance improvements • Correctness ﬁxes • None of them visibleMonday, 21 May 12 20

FINALLY SHIPPING! • Puppet 3.0.0 • Facter 2.0.0 • Hiera 1.0.0Monday, 21 May 12 21

COMMITTING TO SEMVER • Semantic Versioning FTW • We are moving all our projects over • SemVer 2.0.0-rc.1 compliantMonday, 21 May 12 22

IT’S VERSION-CEPTION!Monday, 21 May 12 23

MAJOR VERSION Breaking ChangesMonday, 21 May 12 24

MINOR VERSION Compatible new featuresMonday, 21 May 12 25

PATCH VERSION Bug ﬁx with no other behavioural or functional changesMonday, 21 May 12 26

WHICH MEANS? • You have version numbers that match the way we write and ship code • You can be conﬁdent about the scope of changes in any releaseMonday, 21 May 12 27

SHIPPING CODE FASTERMonday, 21 May 12 28

OS PACKAGES FOR RELEASE CANDIDATESMonday, 21 May 12 29

MONTH DEVELOPMENT RELEASES • Waldorf is the next major release after Telly (3.0.0) • We will ship a tested version every month as a preview • This way you don’t have changes a year old before they ship to the community • Plus OS packages!Monday, 21 May 12 30

NOT DONE YET...Monday, 21 May 12 31

OLD MISTAKES STILL HAUNT US • Parameterized classes don’t work everywhere • undef vs nil • classes with ‘-’ in the nameMonday, 21 May 12 32

SLOW MOVING ECOSYSTEM • Dashboard has not gotten a lot of love recently • Puppet Labs modules need more attention • ...but we are starting to invest in them.Monday, 21 May 12 33

BROKEN (OR DELAYED) PROMISES • import isn’t deprecated • The static compiler isn’t the default • Facter doesn’t have typed or structured factsMonday, 21 May 12 34

THE FUTUREMonday, 21 May 12 35

THE ECOSYSTEM • Shipping structured and typed facts without the ecosystem is a no-go • On release, new features should work everywhereMonday, 21 May 12 36

THE NEXT CHALLENGE Waldorf, kicking ass and taking namesMonday, 21 May 12 37

EXPERIMENT ONE We are going to ﬁx some high-voted ticketsMonday, 21 May 12 38

VOTES SHAPE THE ROADMAP • We said votes matter before • It wasn’t really true •I don’t expect you to believe me this time... • ...so we are gonna ﬁx tickets, then ask you to believe usMonday, 21 May 12 39

VOTES SHAPE THE ROADMAP • We want community input into the roadmap • This seems a solid choice • Success is that votes get used by the community • ...and that we use them to shape the roadmap!Monday, 21 May 12 40

SCHEDULE TRANSPARENCYMonday, 21 May 12 41

REDMINE “ACCEPTED” TICKETS This is the scrum “unsorted product backlog”Monday, 21 May 12 42

REDMINE “3.X” TARGET VERSION This is “we might ﬁx it before 4.0.0”Monday, 21 May 12 43

SAME THING!Monday, 21 May 12 44

GONNA FIX THAT UP • Target open tickets at the next numeric version • Means “trying to ﬁx for that release” • Stillshipping time-based product, so things will missMonday, 21 May 12 45

OTHER EXPERIMENTS You bring ‘em, We try ‘emMonday, 21 May 12 46

TECH FOR WALDORF This is all speculative, no promises.Monday, 21 May 12 47

SYSTEM MODULE PATH • Modules can move fast • Batteries-included is great • Combine them! • Best of both worldsMonday, 21 May 12 48

STATIC COMPILER • Missed Telly, but only just • Content reference, not URI • Single ﬁle catalog? • Easier push model?Monday, 21 May 12 49

STRUCTURED FACTS • Really, structured and typed • JSON is the template for supported types and structures • Full ecosystem support • Third party facts only, initiallyMonday, 21 May 12 50

BETTER GRAPH PROCESSING • Improve graph handling in the Puppet Agent • Fix the “anchor” pattern • Improves from O(N^2) worst case to O(N) • Allows future improvements to the catalog and graphMonday, 21 May 12 51

BETTER ENVIRONMENTS • Different versions of a type in different environments • Turns out that is pretty hard (thanks, Ruby) • We will make it easy • Fix performance cost tooMonday, 21 May 12 52

CLEANER, DOCUMENTED CODE • Easier to use Puppet as a library or extend it • Better API deﬁnitions • Richer integrationsMonday, 21 May 12 53

MY REAL GOALMonday, 21 May 12 54

BUILD A 10× TEAM ...and let them work with the community to be awesome!Monday, 21 May 12 55
