hash generation for PR Service?

hash generation for PR Service?

[Steffen Sledz]

I'm not sure if this is the right mailing list for our problem. Please forgive me if not (and tell me the right one).


We're investigating some problems related with package versions going backwards using a PR Service[1].

Can someone give some hints where we can get information about generation of the hashes which are used to request values from the PR service? Especially which data/files/directories are involved..

The hashes are the same hashes bitbake itself uses to decide whether to
reexecute tasks or not and are the same hashes encoded into the sstate
objects.

The manual gives information about this:

http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#checksums

Please read and understand that, then if you have specific questions,
please ask them and you may get a more targeted answer. At the moment
the question is not specific enough to be easy to answer.

Cheers,

Richard
