[Libguestfs] [PATCH 0/7] Add tar compress, numericowner, excludes flags.

https://bugzilla.redhat.com/show_bug.cgi?id=847880 https://bugzilla.redhat.com/show_bug.cgi?id=847881 This patch series adds various optional arguments to the tar-in and tar-out commands. Firstly (1/7) an optional "compress" flag is added to select compression. This makes the calls tgz-in/tgz-out/txz-in/txz-out deprecated, and expands the range of compression types available. Secondly (2/7) we add an optional numericowner boolean to tar-out, which generates numeric UIDs/GIDs in the resulting tar file. The remaining patches allow us to encode the '--exclude=PATTERN' argument to tar. We add an OStringList type to the generator for passing optional lists of strings. Then we modify tar-out so that this can be translated into zero or more '--exclude' arguments to tar. Note that OStringList is not yet implemented for GObject bindings. Rich.
