Revision as of 07:27, 2 June 2016

This page should be used to keep track of items which should be added to the migration guide. It's a living document for the life of a development cycle and by M4 should represent a significant proportion of items that are worthy of note in the migration guide. Once the migration guide for a release has been completed the contents of this page should be archived in a versioned subpage (i.e. FutureMigrationGuide/2.2)

2.2 Migration Guide items

How we stage directories in sysroot has been simplified and introduces some new variables (SYSROOT_DIRS, SYSROOT_DIRS_NATIVE, SYSROOT_DIRS_BLACKLIST). See the v2 patch series on the OE-Core mailing list: http://lists.openembedded.org/pipermail/openembedded-core/2016-May/121365.html
bitbake now requires python 3.4+
the metadata now requires to use python3 syntax. There are many python3 porting guides out there, or the conversion commits for Bitbake and OE-Core can be used as a guide for changes. Particular areas of note are subprocess command line pipes needing locale decoding, the syntax for octal values changed, the iter*() functions changed name, iterators now return views, not lists and some python modules changed names.
