* It is not extracted (because it is excluded)
* If it's not present in the archive, then an error is
reported (because the file was requested and not found)
* If it is present in the archive, no error is reported.
Previously, this would always report an error because the
exclusion prevented the entry from matching the inclusion.
Also, tar is now more reluctant to report unmatched inclusions.
Previously, "tar x file1 'file*'" against an archive that contained a
single entry "file1" would match file1 and then report an error for
the second pattern because it wasn't matched. It now considers both
inclusions to be matched and reports no error.
isolate common code used by tar and cpio (and useful to other
libarchive clients). The functions here are prefixed with
"lafe" (libarchive front-end) to indicate their use.
is sufficiently different that it was simpler to just put separate
reporting functions into read.c and write.c rather than try to have
a single all-purpose reporting function.
Switch to a custom function for converting int64_t to a string; in
the portable version, this saves a lot of configuration headaches
trying to decipher the platform printf().
use -b 2048 (1MiB block size). Setting the limit to 8192 should
allow some room for growth while still helping people who mistakenly
put in byte counts here instead of block counts.
* Add xz and lzma compression options
* Rename --format-options to simply --options
* Add --same-owner for GNU tar compat
* Add -lmd and -lcrypto to fix link
* Documentation
Translate getdate.y into C for portability. Make the get_date()
function easier to test as well:
* Have it accept a time_t "now" to use as a reference so that test
code can verify relative time specifications against known starting
points.
* Set up default date after parsing the string so that we
can use the specified timezone (if any) instead of the local
default. Otherwise, local DST makes it almost impossible to
reliably test time specifications such as "sunday UTC"
archive_read_disk API to pull metadata off of disk. This
removes a lot of platform-specific knowledge of things like
ACLs, file flags, and extended attributes from bsdtar.
