Subject: [PATCH] Fix mtce-guest not rebuilt after mtce-common
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A recent change to stx-metal/mtce-common broke
the nightly StarlingX build due to stx-nfv/mtce-guest
build failure.

This occurred after a stx-metal/mtce-common change
removed a structure member that the stx-nfv/mtce-guest
compile required.

Since mtce-guest was not rebuilt automatically
the pending compile error was not noticed during UT and
the update was delivered only to show
up as a nightly build failure.

This commit recreates $MY_REPO/cgcs-tis-repo/dependancy-cache
running create_dependancy_cache.py every time when
any rpms and srpms changes, to keep the stx cache updated.

The rpms/srpms changes are detected using the repodata files:
The repodata filenames includes it’s own sha256 in their name,
this is useful to detect rpm/srpms by only comparing the filenames.

Closes-Bug: #1804687
