Robert Yang 1e6d0da8d5 bitbake-whatchanged: print what is about to happen
* Contents:
  - Summary
  - Usage
  - Implementation summary
  - Output
  - TODO

* Summary:
  This is used for printing what is about to happen between the current and last
  builds, for example:

  $ bitbake core-image-sato
  # Edit some recipes
  $ bitbake-whatchanged core-image-sato

  The changes will be printed.

* Usage:
  bitbake-whatchanged [[opts] recipe]

* Implementation summary:
  - Use the "STAMPS_DIR=<path> bitbake -S recipe" to generate the new
    stamps, compare these stamps to the one in the old stamps dir (tmp/stamps),
    so we will get what are changed.

  - When the "-v" (verbose) is not specified:
    > Figure out the newly added tasks
    > Figure out the PV (including PE) and PR changed tasks
    > The left tasks are the ones that the "Dependencies" changed tasks

  - When "-v" is specified:
    > Figure out the newly added tasks
    > Use bb.siggen.compare_sigfiles to figure out the details

* Output, for example (core-image-sato with different git tags)
  and with recipes upgraded):
  - without "-v":
    Figuring out the STAMPS_DIR ...
    Generating the new stamps ... (need several minutes)
    === Newly added tasks: (5 tasks)
      core-image-sato: do_configure do_populate_lic do_install do_rootfs do_compile
      # Note: This is because the "bitbake -S" always generate the sigdata for
      # do_compile, do_rootfs and other task, we may need fix this from "bitbake -S"

    === PV changed: (130 tasks)
      alsa-utils: 1.0.25 -> 1.0.26
      cross-localedef-native: 2.16 -> 2.17
      eglibc-initial: 2.16 -> 2.17
      [snip]

    === Dependencies changed: (3593 tasks)
      busybox: do_package do_package_write do_build do_packagedata do_populate_sysroot do_install do_compile do_package_write_rpm do_configure do_populate_lic
      atk-native: do_compile do_package_write_rpm do_package do_configure do_populate_sysroot do_install do_populate_lic do_patch do_packagedata do_build do_package_write do_unpack
      [snip]

    === Summary: (3728 changed, 1134 unchanged)
    Newly added: 5
    PV changed: 130
    PR changed: 0
    Dependencies changed: 3593

    Removing the newly generated stamps dir ...

  - with "-v":
    === Newly added tasks: (5 tasks)
      core-image-sato: do_configure do_populate_lic do_install do_rootfs do_compile

    === The verbose changes of glib-2.0-native.do_do_install:
    Hash for dependent task virtual:native:glib-2.0_2.34.3.bb.do_compile changed from bab8b8dd95be1b83dcec93f755b1812b to 70f746df7809acaa52de204b0685abb4

    [snip]

    === Summary: (3728 changed, 1134 unchanged)
    Newly added: 5
    Dependencies changed: 3723

    Removing the newly generated stamps dir ...

* TODO
  - It seems that the "bitbake -S core-image-sato" has bugs, it would always
    report errors, but doesn't fatal errors

  - The gcc-cross' stamps are in tmp/stamps/work-shared, but the
    "bitbake -S" doesn't put the stamps in work-shared.

  - The "bitbake -S" always generates the sigdata for image recipe's do_compile,
    do_install and other tasks, we may need fix this from "bitbake -S".

  - Print the ones which can be installed from the sstate.

README

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most everything else should be sent to the OpenEmbedded Core mailing list.  If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
    openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix
      of oe-core and poky-specific files.
