# Run a group of kvm.sh tests on the specified commits. This currently

# unconditionally does three-minute runs on each scenario in CFLIST,

# taking advantage of all available CPUs and trusting the "make" utility.

|
# In the short term, adjustments can be made by editing this script and

# CFLIST. If some adjustments appear to have ongoing value, this script

# This script considers its arguments one at a time. If more elaborate
|
||
|
|
# specification of commits is needed, please use "git rev-list" to
|
||
|
|
# produce something that this simple script can understand. The reason
|

|
|
# for retaining the simplicity is that it allows the user to more easily
|
||

|
# see which commit came from which branch.

|
|
# This script creates a yyyy.mm.dd-hh.mm.ss-group entry in the "res"
|
||
|
|
# directory. The calls to kvm.sh create the usual entries, but this script
|
||
|
|
# moves them under the yyyy.mm.dd-hh.mm.ss-group entry, each in its own
|
||
|
|
# directory numbered in run order, that is, "0001", "0002", and so on.
|
||
|
|
# For successful runs, the large build artifacts are removed. Doing this
|
||
|
|
# reduces the disk space required by about two orders of magnitude for
|
||
|
|
# successful runs.
