scripts/osmo-build.sh / ARTIFACT_STORE: remove
This script was supposed to cache already built Osmocom libraries. But it was only used with openbsc, didn't work as expected anymore (looking at openbsc-master, it just builds all deps from source without caching) and will be replaced with logic that allows using ccache in a future patch. Using ccache has the big advantage that we can cache all build objects where the source files did not change, and not just do it on a dependency level. Oftentimes only few source files change in our patches, so we can really cache everything else that is not affected within any git repository and not just a dependency that didn't change. ccache also does automatic cache size management to ensure a cache stays within a given size limit.

# This script enables artifacts holding dependencies on a jenkins job level to
|
||||
# speed up builds. Basically, it holds logic to check whether the necessary artifact
|
||||
# is available. If so it fetches artifact, unpacks it and if cp/tar succeeded
|
||||
# it triggers the actual build.
|
||||
#
|
||||
# Otherwise it simply builds all dependencies from source by using osmo-build-dep.sh
|
||||
# and archives deps to the ARTIFACT_STORE afterwards. Revisions of locally built
|
||||
# dependencies are detrmined after dependencies are built to ensure catching new
|
||||
# changes in dep_n+1 meanwhile building dep_n.
|
||||
#
|
||||
# Furthermore, ARTIFACT_STORE environment variable has to be set on all jenkins slaves.
|
||||
# The JOB_NAME variable will be injected to each jenkins' job by jenkins itself.
|
||||
# When using script within a docker container one must inject jenkins' JOB_NAME variable
|
||||
# to the container and ensure that ARTIFACT_STORE is mounted to the container's
|
||||
# internal ARTIFACT_STORE.
|
||||
#
|
||||
# Artifacts will be stored as follows:
|
||||
#
|
||||
# $ARTIFACT_STORE/$JOB_NAME/<dep_1>.<branch_1>.<rev_1>_...
|
||||
# ..._<dep_n>.<tag_n>.tar.gz
|
||||
#
|
||||
# Note: each matrix-build has its own directory inside ARTIFACT_STORE.
|
||||
#
|
||||
# In order to make use of osmo-build.sh one needs to source it, e.g. from
|
||||
# ./contrib/jenkins.sh. Furthermore, jenkins should check out the git tree of
|
||||
# the project to be built in the workspace root. Following functions needs to be
|
||||
# declared within a build script that sources osmo-build.sh:
|
||||
#
|
||||
# - artifact_name()
|
||||
# - build_deps()
|
||||
# - build_project()
|
||||
#
|
||||
# This is an example for building "libosmo-netif" which depends on "libosmocore"
|
||||
# and "libosmo-abis".
