We have a project in our local OBS instance where we are encountering some
build dependency issues.

Our OBS is running on an appliance: obs-server-2.3.1-6.7.x86_64

To illustrate the problem:

Let's assume we have 5 packages in a project (pkg1, pkg2, pkg3, pkg4, pkg5)

The pkg2 spec file contains a "BuildRequires:" for one of the rpms generated
by pkg1.
Similarly the pkg3 spec file contains a "BuildRequires:" for one of the rpms
generated by pkg2 and so forth.

When a commit was made to pkg1, it got rebuilt and this triggered pkg2 to
start building. While pkg2 was rebuilding, pkg3, pkg4 and pkg5 went into a
blocked state (which is what we expected).

However, after pkg2 finished building, pkg-3/4/5 get unblocked and do NOT get
rebuilt.

Did you check the buildlog? Perhaps "build compare" triggered and found the
builds identical?

[MF] Yes, the buildlog does detect changes in the generated rpms as per the
build compare. Note, that I tried the exact same scenario in a
home:mfernand:debug project and the dependent packages all build fine there.
It's just this one project which is exhibiting these issues.

What is the project meta and the repository rebuild strategy?
[MF] This is an extract of the project meta:
<repository rebuild="direct" name="standard">
<arch>armv8el</arch>
<arch>i586</arch>
<arch>armv7el</arch>
</repository>

We tried to wipe the binaries of pkg1 and saw the same behavior.
Also wiped the binaries of pkg2 and saw the same behavior for its dependent
packages.

Trying to understand how these dependencies work from an OBS perspective.
Can you please shed some light on this as well as provide some advice on how
to debug this further.

This can be configured on a project level... project meta, build-compare ...
might influence it.
[MF] I'm not sure how to configure build-compare via the project meta. Can you
please elaborate on this.

Thanks,

Mal
