63165a380d Fix the copyright notice; it was always intended to be
a vanilla 2-clause BSD license, but somehow some confusing
extra verbage get copied from somewhere.

Also, update the copyright dates to 2007 for all of the files.

Prompted by: several questions about what those extra words really mean

ca743d5c67 Change the internal API for writing data to an entry; make the
internal format-specific functions return the same as the public
function, so that the public API layer doesn't have to guess the
correct return value.  This addresses an obscure problem that occurs
when someone tries to write more data than the size of the entry (as
indicated in the entry header).  In this case, the return value from
archive_write_data() was incorrect, reflecting the requested write
rather than the amount actually written.

aa1eeda578 Portability and style fixes:
* Actually use the HAVE_<header>_H macros to conditionally include
    system headers.  They've been defined for a long time, but only
    used in a few places.  Now they're used pretty consistently
    throughout.
  * Fill in a lot of missing casts for conversions from void*.
    Although Standard C doesn't require this, some people have been
    trying to use C++ compilers with this code, and they do require it.

Bit-for-bit, the compiled object files are identical, except for
one assert() whose line number changed, so I'm pretty confident I
didn't break anything.  ;-)

8aaa8fe733 Add a lot of error checks, based on the patches provided by Dan Lukes.
Also fixes a memory leak reported by Andrew Turner.

3ede53f3e1 Clean up the error handling in the
write path.  In particular, this should
solve some problems people have seen with
bsdtar not exiting on various write errors.

d911e48507 * Plug a buffer overrun in ACL parsing. (archive_entry.c)
* Re-use a single buffer for shar output formatting rather
   than hammering the heap. (archive_write_set_format_shar.c)
 * Fix a handful of minor memory leaks and clean up some of the
   memory-management code.

aee47dd7c8 More work on ACLs: fix error in archive_entry's ACL parsing code,
try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files

df3c1316b0 Many fixes.
Portability: Thanks to Juergen Lock, libarchive now compiles cleanly
on Linux.  Along the way, I cleaned up a lot of error return codes and
reorganized some code to simplify conditional compilation of certain
sections.

Bug fixes:
  * pax format now actually stores filenames that are 101-154
    characters long.
  * pax format now allows newline characters in extended attributes
    (this fixes a long-standing bug in ACL handling)
  * mtime/atime are now restored for directories
  * directory list is now sorted prior to fix-up to permit
    correct restore of non-writable dir heirarchies

2710e4d1ef Initial import of libarchive.
What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.
