Usage: scripts/run-sisyphus-set9-d1-bench.sh
|
||
|
||
The script has no positional arguments. Configuration is passed through env:
|
||
CPU=2 ROUNDS=3 RESET_WORK=1 ./scripts/run-sisyphus-set9-d1-bench.sh
|
||
RESET_WORK=0 OPERATIONS='unmet check' ./scripts/run-sisyphus-set9-d1-bench.sh
|
||
|
||
Main variables:
|
||
WORK_ROOT, RESULT_DIR, SISYPHUS_MIRROR, RPM_GIT, RPM_BRANCH, PACKAGER,
|
||
SET9_C, D1_C, PKGLIST_CONVERTER, CPU, ROUNDS, RESET_WORK, OPERATIONS.
|
||
|
||
RESET_WORK=1 removes WORK_ROOT after running hsh --cleanup-only for old hasher
|
||
workdirs. Timed runs never update repositories and never install packages.
|
||
Snapshot preparation downloads x86_64 and noarch metadata from SISYPHUS_MIRROR
|
||
into an isolated APT directory under WORK_ROOT; host APT configuration is untouched.
