Ulf Magnusson 4d2658eeee task-time: Add simple buildstats analysis script 
The 'task-time' Python script is used for simple manual analysis of
buildstats. It displays task timing information in the same format (and
using the same calculation) as the Bash 'time' builtin, and can
optionally sort tasks by real (wall-clock), user (user space CPU), or
sys (kernel CPU) time used.

The timing information comes from the getrusage(2) fields added by
commit adfdca4df1 ("buildstats: Improve to add getrusage data and
corrected IO stats"). That commit is required for the script to work.

Example 1: Running 'task-time' on a specific task buildstat:

  $ task-time ./20161005235448/gettext-0.16.1-r6/do_compile
  ./20161005235448/gettext-0.16.1-r6/do_compile:
  real  0m54.560s
  user  0m46.028s
  sys   0m2.772s

Example 2: Running 'task-time' on a directory, sorting on wall-clock
time:

  $ task-time tmp/buildstats/20161018083535 --sort real
  tmp/buildstats/20161018083535/bash-4.3.30-r0/do_fetch:
  real    10m59.140s
  user    0m1.152s
  sys     0m0.320s

  tmp/buildstats/20161018083535/readline-native-6.3-r0/do_fetch:
  real    8m57.310s
  user    0m0.860s
  sys     0m0.288s

  tmp/buildstats/20161018083535/perl-5.22.1-r0/do_compile:
  real    4m28.840s
  user    4m1.348s
  sys     0m15.816s

  ...

Example 3: Running 'task-time' on all do_compile buildstats for a
particular build by using shell globbing, sorting on user space CPU
time:

  $ task-time tmp/buildstats/20161018083535/*/do_compile --sort user
  tmp/buildstats/20161018083535/qemu-native-2.7.0-r1/do_compile:
  real    0m49.570s
  user    21m45.236s
  sys     1m44.380s

  tmp/buildstats/20161018083535/linux-yocto-4.8+gitAUTOINC+03bf3dd731_67813e7efa-r0/do_compile:
  real    0m49.530s
  user    21m39.588s
  sys     1m59.576s

  tmp/buildstats/20161018083535/gcc-cross-i586-6.2.0-r0/do_compile:
  real    1m8.130s
  user    15m54.256s
  sys     1m28.776s

  ...

Example 4: Comparing a task between two builds:

  $ task-time 201610052{25856,35448}/gettext-0*/do_compile --sort real
  20161005235448/gettext-0.16.1-r6/do_compile:
  real	0m54.560s
  user	0m46.028s
  sys	0m2.772s

  20161005225856/gettext-0.19.8.1-r0/do_compile:
  real	0m41.520s
  user	2m17.312s
  sys	0m7.536s

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 = "nodistro") 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 (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:

bitbake:
    Git repository: http://git.openembedded.org/bitbake/
    Mailing list: bitbake-devel@lists.openembedded.org

documentation:
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
    Mailing list: yocto@yoctoproject.org

meta-poky, meta-yocto-bsp:
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
    Mailing list: poky@yoctoproject.org

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.

    Git repository: http://git.openembedded.org/openembedded-core/
    Mailing list: 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.
