* catch SIGSEGV as well; register sa_handlers only if its SIG_DLF beforeFlorian Fischer2019-09-295-31/+40

* catch if cmd abortsFlorian Fischer2019-09-293-2/+33
| | | | | | perf stat does not propagate if the measured cmd aborts. To solve thing in a universal way we register a SIGABRT handler which creates the file aborted

| * use ArchiveArtifacts for all benchmark resourcesFlorian Fischer2019-09-237-179/+90
| |
| * Add ArchiveArtifactsFlorian Fischer2019-09-225-15/+78
| | | | | | | | | | | | | | ArchiveArtifacts check a downloaded archive against a provided checksum. The Archive is downloaded to cache/<name>/<name>.<format>. The only suported format is tar. ArchiveArtifacts can be used as sources of an Allocator.

| * add artifactsFlorian Fischer2019-09-212-9/+96
| | | | | | | | | | | | | | | | | | Artifacts are downloadable external ressources. They provide their ressource (vcs commit, extracted archive) using Artifact.provide. GitArtifact download a bare git repository and provides specific commits using worktrees. Use GitArtifact for the linux kernel source

* don't exit if we fail to prepare a benchmarkFlorian Fischer2019-09-114-18/+12
| | | | | benchmark.prepare should raise an Exception if it encounters an unrecoverable, intolerable error.
* explicitly collect binary versionsFlorian Fischer2019-09-116-4/+21
| | | | | | | There is no generic way to retrieve the version of a binary. Not everyone followes GNU cli guidelines and supports "--version". The larson benchmark for example reads input from stdin when started with "larson --version" blocking the Benchmark.prepare() call.
