Re: [Libguestfs] [PATCH 5/5] mllib: add a new run_command helper

Add a simple helper to run a command from a sequence of arguments, without using a shell: this should help reducing the amount of quoting ineeded, since arguments are passed straight as such. Make use of it in the places currently using shell_command, and which don't assume they can run anything (so no shell redirections, `env`, etc). --- builder/builder.ml | 62 ++++++++++++++++++-------------------- builder/cache.ml | 4 +-- builder/downloader.ml | 8 ++--- builder/sigchecker.ml | 4 +-- dib/dib.ml | 57 ++++++++++++++--------------------- dib/utils.ml | 6 ++-- mllib/common_utils.ml | 15 +++++++++ mllib/common_utils.mli | 6 ++++ v2v/copy_to_local.ml | 4 +-- v2v/input_libvirt_vcenter_https.ml | 7 ++--- v2v/input_ova.ml | 12 ++++---- v2v/output_glance.ml | 23 +++++++------- v2v/output_libvirt.ml | 15 ++++----- v2v/output_rhev.ml | 9 +++--- v2v/v2v.ml | 21 ++++++------- 15 files changed, 124 insertions(+), 129 deletions(-)
