3. Release Compilation

4. Why do we have builds?
• Code Compilation
• Functionality Compilation
• Deployment Compilation
• Feedback

5. Builds and tests are made to be broken

6. What’s beautiful?
• See flow
• Ease of change
• Coherent

7. Recommendations
• Use the right tools for build and CI
• Use the right patterns to allow extra benefits

8. Part of a Build Process
• Build Script/editor
• Build Server / CI Server
• Build Environments

9. What’s the difference?
• Automated Build (what to do)
• Continuous Integration (when to do it)

10. Declarative
• [Ant, nant,msbuild] (http://ant.apache.org/)
• [Automake] (http://www.gnu.org/software/automake/)
• [Boost Build] (http://www.boost.org/doc/tools/build/index.html)
• [Cmake] (http://www.cmake.org/)
• [Make] (http://www.gnu.org/software/make/)
• [Ocamlbuild] (http://gallium.inria.fr/~pouillar/)
• [Omake] (http://omake.metaprl.org/index.html)
• [Qmake] (http://doc.trolltech.com/4.2/qmake-manual.html)
• [Rake] (http://rake.rubyforge.org/)
• [SCons] (http://www.scons.org/)
• [Waf] (http://code.google.com/p/waf/)

11. Xml Build Scripts (Ant) - declarative

12. Procedural
• FinalBuilder
• Visual build pro
• Batch files
• Powersell scripts

13. Build Scripts (Bat)
Procedural

14. Domain Specific
Language Build
Scripts (Rake)
declarative

15. Visual Build Scripts (FinalBuilder)

16. Which one?
• Visual editing allows seeing FLOW
• Easy to update and change by newbies
• Easy to debug
• FinalBuilder or Visual Build Pro on windows
• Rake on linux or mac

17. The Right CI Tools

18. TeamCity

19. Jenkins

20. CruiseControl

21. Hudson

22. Many others. Which one?
• TFS? TeamCity?
• Support build agents
• Support amazon ec2 auto scaling agents
• Easy to setup and maintain
• Free for a small team
• TeamCity is awesome

23. But some CI servers support build
actions too!

24. Hardware
• Build Machine (with teamcity)
– + agent machines (optional)
• Test Machine
• Staging Machine
• Production Machine
• This can all be in the cloud (EC2 is wonderful)

25. Build Configurations
• Continuous Integration Build
• Slow Build (nightly, optional)
• Deploy to test servers
• Deploy to staging servers (optional)
• Deploy to production

27. Build Script Injection
• Allow version aware builds
• Build scripts are part of source control
• Build configurations on the CI server are dumb
triggers

28. Fill In The Blanks
• Build Script uses placeholders for system
related knowledge
• Placeholders are filled from environment
variables or other types of parameters to the
command line
• These variables are SET by the Build
Configuration on the CI server

30. Location Agnostic Scripts

31. Extract Script

32. Build Chain Triggers
Triggered by checkin
Triggered by end of previous
Manual
Manual

33. Slow Builds
Do X
Do X + Y
Do X + Y + Z
Do X + y + Z + N

34. Cumulative, Fast Builds
Do X
Do Y
Do Z
Do N

35. How Fast?

36. Shipping Skeleton
• Start by releasing
• Deploy a hello world empty skeleton
• Then fill out the product
• Continue adding small build features as you go
along

38. Short Song?

39. This is a test line

40. It looks like you’re doing just fine

41. The was a bomb in the kiev airline

42. The build song
Why this song?

43. Every build you break
• Refactoring you make
• Every mock you fake
• You little snake
• I’ll be watching you

44. • Every stand up meeting
• I believe you’re cheating
• Every unit test
• Pains my chest
• I’ll be stopping you

45. • Oh can’t you see?
• This is scaring me
• Every time we deliver
• I begin to shiver

46. • When you say “transparent”
• My fear is apparent
• ‘Hide reality’
• Is my mentality
• I’ll be stopping you

47. • Oh can’t you see
• I would rather ski
• Dealing with this change
• Is gonna feel so strange

48. • Every build you break…
