46 * deflate.c: Likewise.
49 * inflate.c: Likewise.
51 * revision.h: Likewise.

90 directories that we read.
91 (open_and_stat, open_input_file): New functions.
92 (do_stat, get_istat): Remove; most of the contents went to these new
94 (make_ofname): Don't use WARN, as it affects exit status.
95 (get_method): When the original file name was truncated,
96 restore from its base name, not from its full name.
97 (do_list): Avoid undefined behavior with out-of-range time stamps.
98 ctime, for example, cannot be invoked on arbitrary time stamps safely,
99 since it might overrun an internal buffer. Do not assume that
101 (copy_stat): Do not remove input file; that's now the caller's
102 responsibility. This avoids a problem if there is a write error
103 when the caller closes the output file.

126 (xalloc_die): New function.
127 (xmalloc): Remove; no longer needed.

214 Suggested by <antos@MAST.queensu.ca>.
216 2002-09-28 Paul Eggert <eggert@twinsun.com>
218 * zforce.in: Use shell pattern matching instead of 'expr', which
219 mishandles names like "+". Remove old check for 14-byte file
220 names on hosts with broken "mv" implementations, as such systems
221 aren't in use any more and it's better nowadays to support file
222 names longer than 14 bytes. Rely on "mv"'s error-reporting.
223 This fixes a portability bug reported by Ralf Neubauer, along
224 with some other bugs.
226 Remove dangling output symlinks properly.
227 Bug reported by Kalle Olavi Niemitalo.
228 * gzip.c (lstat): New macro, for platforms lacking lstat.

243 * gzexe.in (PATH): Set to same as other programs.
244 Don't assume "tail +22" works; POSIX removed this.
245 Check against compressing "tail".
246 Check against "skip=" line with no integer.
247 * zgrep.in: Exit with status 2 if trouble, for consistency with grep.
249 * gzip.c (main): Avoid core dump in diagnostic message if
250 incorrect suffix is given.
252 2002-09-26 Paul Eggert <eggert@twinsun.com>
254 * zdiff.in: Use "trap -" instead of "trap". Patch by Nicolas Boullis.

275 * Makefile.am (AM_MAKEINFOFLAGS): Add --no-split.
276 (gzip_TEXINFOS): New macro.
278 * tailor.h (NO_DIR): Define to 1, not the empty string.
279 * gzip.c (NO_DIR): Define to 0 if not defined. All uses changed.
280 (usage): Don't put '#if' inside printf, as the C standard says
281 that it is not portable if printf is a macro.
283 Don't lose output when decompressing truncated input.
284 Bug reported by Nadav Har'El.
285 * inflate.c (GETBYTE): New macro.
287 (inflate_dynamic, inflate_block): Add a local variable w, needed

510 Revision 1.2.4.4294967303, dated today.
512 * gzip.c (get_method): Don't complain about trailing zeros at
