18 # This entry script does not change CSIT branch,
19 # use "with_oper_for_vpp.sh" wrapper for that.
22 # + There is a directory holding VPP repo with patch under test checked out.
23 # + It contains csit subdirectory with CSIT code to use (this script is there).
24 # + Everything needed to build VPP is already installed locally.
26 # + At the end, VPP repo has parent commit checked out and built.
27 # + Directories build_root, build and csit are reset during the run.
28 # + The following directories (relative to VPP repo) are (re)created:
29 # ++ csit_new, csit_parent, build_new, build_parent,
30 # ++ archive, csit/archive, csit_download_dir.
32 # TODO: Implement some kind of VPP build caching.
34 # "set -eu" handles failures from the following two lines.
