13e5b34e5b fix "zcat -f" on normal files. fixes PR#26145 2004-07-03 09:39:30 +00:00
mrg
3c372acd10 if there are zero bytes to output, this isn't an error. it's probably 
a zero length file.  don't return an error.  this should fix PR#25994.

c6c68fa810 handle_pathname: if it's stdin, return after handling it, rather than 
trying to then process "-" as a file afterwards.  fixes PR#25843.

11153dbc8d - maybe restore the timestamp 
- don't create the output file with "-l"

both from geoff wing with a few mods by me.

9e9fa78434 explicitly lseek() to offset 10 to read the original name. fixes a 
latent bug awoken by rev 1.37 (prior versions always left the fd at
this offset purely by chance.)  fixes PR#25824.

9b954397e0 use "zcat -fq" not just plain "zcat". this lets zgrep work on non 
compressed files (as reported by simonb) as well as not printing
random warnings that zgrep isn't ready to handle.

2d5e05af49 - fix "gzip -t" to not output anything by default. PR#25507 
- fix any decompression on corrupted gzip files.  PR#25508
- ask to overwrite files if we have a tty, rather than failing the
  operation.  PR#25509.
- clean up maybe_err()/maybe_warn(): use maybe_err() only for fatal
  errors.  maybe_warn() is for processing errors.  this allows
  "gzip -d file1.gz file2.gz" to decompress file2.gz even if file1.gz
  is corrupted, etc.
- change the internal compressor/decompressor API to return "-1" on
  failure, not 0.  this allows for 0-sized files to be decompressed
  correctly.

5fe88849a1 WARNS=3: add some const poisoning, and sort out local variable 
definitions shadowing other variables.

Pass storage for file names into the file_compress and file_uncompress
functions, so that we don't run the risk of leaking memory. Remove a global
variable that's no longer needed.

f8dc59869d Fix a reference to stale storage on the stack - malloc the new file 
name when gunzip'ing via strdup(3).  Fixes a bug whereby the new
filename would appear as gibberish when verbosely gunzipping.

Fix an off-by-one error when allocating the filename with added suffix,
and properly NUL-terminate the new filename.

It's NULL, not 0, in char * assignments - there are some still to do here.

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.
