41bff69bbe Always initialise savename. Fix gzip -c core dump on sparc (and probably 
others). OK'd by mrg@.

99d2aa3dc3 clean up file descriptor handling. don't lose them... 2004-04-27 13:45:50 +00:00

a9c239e635 - the default compression level in GNU gzip is 6 not 5; copy that default. 
- note that -t/-l/-v & bzip2 is not handled the same as gzip in a comment.

1d0e9794a0 significantly rototill. don't use the high-level gzio functions 
anymore, use the low-level inflate()/deflate() directly.  this
allows support file-type detection on stdin; now can decompress
.Z and .bz2 files fed to stdin (fixes PR#25192) additionally it
makes -v work with stdin or stdout (fixes PR#25215.)

(with these changes, we no longer need gzopenfull(3) in libz.)

thanks to martin@ for the code gzip.c:gz_uncompress() is based on.

98445d2478 be sure we don't try to remove an output file we haven't actually created.

ff187e728e - completely rewrite print_ratio(). fixes PR#25072 and a few other cases 
- print_list() was getting the compressed/uncompressed sizes backwards.

8a618ce17c remove a chunk more code with -DSMALL and in the process fix -DSMALL 
that was broken in the previous commit (by exposing "fflag".)

17ebf9b589 Handle files with link count larger than 1 if "-f" option is used. This 
is consistent with the old "gzip" and required by "pkgsrc" to implement
"MANZ" properly.

fix "gzip -l" in -DSMALL (it wasn't doing a stat(2)).

70da2f0f10 patch from tron@ to convert to using public bz interfaces. simonb says 
no reason not to and this fixes PR#24964.

ed20265f67 shave another 612 bytes off -DSMALL on x86. now x_gzip with -l support 
is actually smaller than the older x_gzip without it!

d7f0a538e2 remove a bunch more stuff with -DSMALL. now we are about 400 bytes larger 
than x_gzip... given we add -l support, time to retire x_gzip/gzip.c.

57a27c0187 remove another 3KB or so of text/data on i386 with -DSMALL. now only 
about 1.1KB larger than the old x_gzip sources, but includes (required
for sysinst) gzip -l support.

4084ec5402 import distrib/utils/x_gzip into usr.bin/gzip, with these enhancements: 
- fully updated manual
	- -n/-N support
	- time stamp/owner/etc saved properly
	- GNU gzip --long-options supported (missing --ascii, --list
	  and --licence)
	- various cleanups & fixes

note that "-n" (save filename) support is currently disabled due to
depending on API changes in zlib.  for now, this support is disabled
(however "gzip -N -d" works.)

this gzip(1) replacement is ready for serious testing.  issues are:
	- might implement --list one day
	- zlib API addition
