Roman Donchenko edae40239e cmArchiveWrite: do not store sparse files when using standard tar formats
Sparse files in tars are a GNU extension that libarchive will use if it
detects holes in the input file, even when using the standard pax/paxr
formats. Not all tar implementations can handle sparse files; in particular,
the internal implementation dpkg uses to extract packages can't. To
maximize archive portability, turn this feature off by clearing the
sparseness information from archive entries.

Nils Gladitz d2cc580704 cmake: Teach "-E tar" command a "--format=" option
Allows specifying a libarchive defined archive format currently restricted to
7zip, gnutar, pax, paxr and zip.

The default is "paxr" (pax restricted).

Brad King 3a60c899fc cmake: Teach "-E tar" command a "--mtime=" option
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk.  This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

Daniel Pfeifer f931a18c33 CPack: add generators for .7z and .tar.xz (#13072, #14519) 2014-07-29 09:48:41 -04:00

Eric NOULARD 1a3ad5c615 Add XZ compress support to libarchive-wrapper
This is not needed but it does not cost much to do it for all
potentially supported format in libarchive. XZ and LZMA are not
builtin libarchive and require external lib but if
CMAKE_USE_SYSTEM_LIBARCHIVE is ON then we may get it for free.

Eric NOULARD b50c15915a Add ZIP archive format and LZMA compress support to libarchive-wrapper
This will be needed to use cmArchiveWrire in cmCPackArchiveGenerator
with the same feature set as before. Note that adding zip
support to libarchive-wrapper would also makes it easy to add
a new -E zip command to cmake commands.
