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
