[OE-core] [PATCH V3 0/3] sstatesig: add support to dump incremental locked signatures

[Hongxu Jia]

How to test incrementally locked signature dump:

1) Create a new build

2) Dump locked sig file for db
$ bitbake -S none db
...
Writing locked sigs to /home/jiahongxu/yocto/build-20140904-yocto/locked-sigs.inc
NOTE: Tasks Summary: Attempted 0 tasks of which 0 didn't need to be rerun and all succeeded.
...

3) Back up locked-sigs.inc
$ cp locked-sigs.inc locked-sigs.inc.bak

4) Dump locked sig file for db again
$ bitbake -S none db
...
Writing locked sigs to /home/jiahongxu/yocto/build-20140904-yocto/locked-sigs.inc
NOTE: Tasks Summary: Attempted 0 tasks of which 0 didn't need to be rerun and all succeeded.
...

5) Compare locked-sigs.inc and locked-sigs.inc.bak to verify nothing changed
$ vimdiff locked-sigs.inc locked-sigs.inc.bak

6) Require locked-sigs.inc
vim local.conf
...
require "${TOPDIR}/locked-sigs.inc"
...

7) Incrementally dump locked sig file for world
$ bitbake -S none world
...
Writing locked sigs to /home/jiahongxu/yocto/build-20140904-yocto/locked-sigs.inc
NOTE: Tasks Summary: Attempted 0 tasks of which 0 didn't need to be rerun and all succeeded.
...

8) Compare locked-sigs.inc and locked-sigs.inc.bak to verify incrementally dumping
$ vimdiff locked-sigs.inc locked-sigs.inc.bak

9) Back up locked-sigs.inc
$ cp locked-sigs.inc locked-sigs.inc.bak

10) Dump for world again
$ bitbake -S none world
...
Writing locked sigs to /home/jiahongxu/yocto/build-20140904-yocto/locked-sigs.inc
Nothing added to /home/jiahongxu/yocto/build-20140904-yocto/locked-sigs.inc
NOTE: Tasks Summary: Attempted 0 tasks of which 0 didn't need to be rerun and all succeeded.
...

11) Compare locked-sigs.inc and locked-sigs.inc.bak to verify nothing changed
$ vimdiff locked-sigs.inc locked-sigs.inc.bak
