Changes of V2:

* Fix a typo fn -> 'fn'

* Use "bitbake -e" rather than "bitbake -e recipe" to get the BB_STAMPS_DIR

* Use "BB_STAMPS_DIR=<path> bitbake -S recipe" to regenerate the stamps

* Change the summary format a little, now it looks like:
  - (without -v):
    === Summary: (3653 changed, 1927 unchanged)
    Newly added: 807
    PV changed: 48
    PR changed: 276
    Depends changed: 2522

  - (with -v):
    === Summary: (3653 changed, 1927 unchanged)
    Newly added: 807
    Depends changed: 2846

So leaving Chris's objections aside for a moment, I applied this and the 
BB_STAMPS_DIR change, and ran the script on my build directory which is out of 
date with respect to the metadata (i.e. metadata has been updated since the 
last build). The output seems to suggest that no changes have been made, which 
is not the case:

----------- snip -----------
$ bitbake-whatchanged core-image-minimal
Figuring out the BB_STAMPS_DIR ...
Generating the new stamps ... (need several minutes)

=== Summary: (0 changed, 0 unchanged)
Newly added: 0
PV changed: 0
PR changed: 0
Depends changed: 0
----------- snip -----------

Cheers,
Paul

Thanks Paul, did you re-run the oe-init-build-env, please? Otherwise the
BB_STAMPS_DIR would have no effect since it would not  be in the BB_ENV_EXTRAWHITE.

It seems that you had re-run the oe-init-build-env since when no BB_STAMPS_DIR
it would print errors., I think that the problem is  the "bitbake -S" didn't
work well since it has bugs, I have updated the related code a little, and it
would tell what's wrong:

         # FIXME
         # The "bitbake -S" may fail, not fatal error, the stamps will still
         # be generated, this might be a bug of "bitbake -S".
         try:
             bb.process.run(cmdline)
         except Exception as exc:
             print(exc)

I have pushed it to git repo, it would be great if you can help me to test it,
and I will invite you beer when you come to Beijing:-)
