What are the new features in zc.buildout since 1.4.4?

Transcript

1. Buildout 2.x Fixing the sins of zc.buildout 1.5.x
2. Buildout 2.x Isolation #fail "Buildout no-longer tries to provide full or partial isolation from system Python installations." "If you want isolation, use buildout with virtualenv, or use a clean build of Python to begin with"
3. Buildout 2.x Insane idea #fail "Buildout no-longer supports using multiple versions of Python in a single buildout"
4. Buildout 2.x Goodbye zc.buildout 1.5, we won't miss you. </end-fail>
5. Buildout 2.x Relative indentation in option values is retained if the first line is blank [mysection] tree = /root branch
6. Buildout 2.x Buildout no-longer installs zipped eggs. The buildout:unzip option has been removed.
7. Setuptools 1.x "Buildout no-longer supports setuptools. It now uses distribute exclusively" Then Distribute and setuptools merged. Now using setuptools only! Huzzah!
8. Version Pinning Built-in picked version printing. No more dumppickedversions [buildout] show-picked-versions = true update-versions-file = picked-versions.cfg
9. Version Pinning The versions option now defaults to versions [buildout] # This is no longer needed, unless # you use a different section name versions = better-versions
10. Version Pinning Version pins can now be simple constraints in addition to being simple versions. [versions] my.package = 1.0 my.dependency >= 1.8.4
11. New Options The socket-timeout option can be set in configuration [buildout] socket-timeout = 5 Which was previously only availble via the -t switch: $ bin/buildout -t 5
12. New Options Buildout now has a --version option: $ bin/buildout --version buildout version 2.2.1
13. New Features Conditional sections [ctl] suffix = [ctl:windows] # If we are on windows, add a .bat suffix = .bat Order matters! If ctl:windows was defined before ctl nothing will happen.
14. New Features Conditional sections can use the follwing builtin variables: sys sys_platform os linux platform windows re cygwin python2 solaris python3 macosx python26 posix python27 bits32 python32 bits64 python33 little_endian sys_version big_endian pypy jython iron cpython
15. New Features Conditional sections can also be expressions (using the builtin variables, etc.): [example] foo = 42 [example:2 + 2 == 4] # this will resolve to true, then modify # the options in this section foo = 1 bar = 2
16. New Features Bootstrap now has an init command. This sets up a part with the distributions specified. NOTE: This creates a new buildout.cfg for you: $ python bootstrap.py init requests Creating '/Users/clayton/Desktop/buildout2/buildout.cfg'. Creating directory '/Users/clayton/Desktop/buildout2/bin'. Creating directory '/Users/clayton/Desktop/buildout2/parts'. Creating directory '/Users/clayton/Desktop/buildout2/develop-eggs'. Generated script '/Users/clayton/Desktop/buildout2/bin/buildout'. Getting distribution for 'setuptools'. Got setuptools 1.1.7. Not upgrading because not running a local buildout command. Installing py. Getting distribution for 'requests'. Got requests 2.0.1. Generated interpreter '/Users/clayton/Desktop/buildout2/bin/py'.
17. New Features Which creates the following buildout.cfg [buildout] parts = py [py] recipe = zc.recipe.egg interpreter = py eggs = requests
18. New Features And makes the following interpreter available $ bin/py >>> import requests >>> requests.get('http://www.sixfeetup.com') <Response [200]>
19. New Features Meta recipe support Provides support for recipes that just provide configuration Able to send options via the meta part in buildout Like anything with meta in the name, might be good to avoid See the Meta recipe docs for more info
20. Misc Enhancements Working set calculation speed up (don't use -v if you don't need it) Smarter extends by url handling (less download attempts) Handle both addition and subtraction of elements (+= and -=) on the same key in the same section Lot's of bug fixes and cleanup. Being actively maintained via Github now!
