# 290073 27-Oct-2015 delphij

Update NetBSD RCS IDs to reflect the changes being upstreamed.

# 290024 26-Oct-2015 delphij

In gunzip(1), treat trailing garbage as a warning and not an error. This
allows scripts to distinguish it between real fatal errors, for instance a
CRC mismatch.

Update manual page for the behavior change.

- Mention xz(1) in gzip(1).
- Strip away path from header name when decompressing.

# 226184 10-Oct-2011 delphij

Incorporate recent changes from NetBSD. Most notable change is the addition
of support of decompressing xz files.

Obtained from: NetBSD


# 222211 23-May-2011 delphij

Match symbolic link handling behavior with GNU gzip, bzip2 and xz:

When we are operating on a symbolic link pointing to an existing
file, bail out by default, but go ahead if -f is specified.

# 206387 07-Apr-2010 delphij

Diff reduction against NetBSD and add myself to AUTHORS section of the
manual page as I wrote the unpack functionality. No actual executable
code change verified with md5(1).


# 194916 24-Jun-2009 delphij

Sync with NetBSD:
- gzip -n does not store timestamp; [1]
- Reduce diff against NetBSD by moving some casts in our local
versions.

Mention 'k' option of gunzip.

Pointed out by: ighighi gmail.com


# 170053 28-May-2007 delphij

Add a '-k' flag which is similar with its bzip2(1) counterpart,
meaning that the user wants the input file to be left intact.

# 167627 16-Mar-2007 delphij

Mention a limitation that was inherted from RFC1952, making
it impossible to obtain correct file size from a file that
is larger than 4GB before compression.

PR: bin/110329
MFC after: 1 week


# 166255 26-Jan-2007 delphij

Replace the GNU gzip with a slightly modified NetBSD gzip. The
NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.

- Because this is a piece of mature code and we want to make
changes so it is added directly rather than importing to
src/contrib.
- Connect newly added code to src/usr.bin/ and rescue/rescue
build.
- Disconnect the GNU gzip code from build for now, they will
be eventually removed completely.
- Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
WITHOUT_BZIP2.
