Developer workflow improvements as documented in the following bugzilla entry:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=6662

Todo list

SDK

• Properly report failures in bitbake execution during install (output is currently discarded)
• Prevent do_rootfs itself from executing on install - we only need the tasks that it depends upon
• Write test script for SDK
• Randy: getting errors from bitbake about changed signatures - behaviour change after Hongxu's patch?
• Update environment setup script to use buildsystem toolchain -- Done but needs testing and function dependent on uninative - Randy
• Fix runqemu(and possibly other tools?) since we no longer have the nativesdk sysroot (Add them to buildtools-lite?)
• Refactor to move functionality to SDK classes rather than meta-newsdk recipe
• nativesdk-qemu-helper_1.0.bb and qemu-helper_1.0.bb don't publish the same set of files. Investigate, since runqemu(and possibly other things) may need to come from the buildsystem's native sysroot.
• Installing the sdk to /opt requires root perms, but if you run the installer under sudo/as root then the inner execution of bitbake to prepare the SDK fails at sanity check
• uninative-tarball errors when restoring from sstate (should it even try?)
• uninative-tarball reports "WARNING: Function doesn't exist" during build
• Error when running recipetool from devtool "Error: The OE SDK/ADT was detected as already being present in this shell environment. Please use a clean shell when sourcing this environment script." - probably need to bypass this check via an extra environment variable
• When publishing the SDK(tool not available yet), warn the user if there are items added to the image/distro via local.conf and suggest moving the items the distro or image config.
• Add a message to the start of the environment script with pointers to the things you can do with it
• Add a note to the generated local.conf/bblayers.conf mentioning that it's auto-generated and warning against editing

devtool

• Need to run do_populate_sysroot when you run "devtool build" (so that libraries can be added)
• Add an option for modify / add to use the same directory for source and build where that's required
• Add support for plugins in multiple layers
• Support 'devtool modify linux-yocto' -- Extract/build working, but modify is missing config creation - Paul
• Use git to track changes made by extra task functions?
• extract: Try to get author/date info about patches from metadata git history if not able to find it any other way?
• update-recipe: warning when running on mdadm: WARNING: Variable key FILES_${PN} ( ${base_libdir}/udev/rules.d/*.rules) replaces original key FILES_mdadm
• 'devtool modify' needs to at least try to get initial revision when -x is not specified - In progress - Paul
• 'devtool deploy-target' needs to be more verbose about ssh failures (just get "lost connection" on e.g. known host key mismatch) - In progress - Paul
• Add option to 'devtool deploy-target' to add "-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" to ssh/scp command - In progress - Paul

recipetool

• Rudimentary spec file conversion?
• Ability to do interactive adds via a UI
• Add comments in on do_configure(_append), do_install_(append) etc.
• Handle USE_* options in Makefiles?
• Extract dependencies from cmake
• LICENSE files can be picked up twice if they match more than one expression in our list e.g. COPYING.GPL
