Robbins <arnold@skeeve.atl.ga.us> + + * io.c (redirect): When finding the rp pointer, if it's not + NULL, set str = rp->value. This gets the '\0' terminated + version. Motivated by bug report from John Hawkinson + (jhawk@bbnplanet.com). + +Sun Jul 14 18:40:26 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * configure.in: Added call to AC_CHECK_LIB(m, fmod), since + apparently some systems have fmod in the math library. + Portability: The Holy Grail. Sigh. + +Sun Jul 14 18:08:01 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * awk.h: Add Jim Meyerings ISASCII etc hacks for ctype macros. + * builtin.c (do_toupper, do_tolower, sub_common): Changed to use + upper-case versions of ctype macros. + * main.c (main): Ditto. + * node.c (r_force_number, parse_escape): Ditto. + +Sun Jul 14 06:34:18 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * field.c (set_record): Made it always do the PERM flag. + Fixes cases where $0 is assigned to, e.g. by gsub, keeps + the fields valid. + (get_field): Removed the call to reset_record in + case where ! field0_valid. We want to leave the fields alone + if they've been changed. + +Thu Jul 11 23:04:20 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * io.c (devopen): Change tests of (flag & O_fooONLY) to + (flag & O_ACCMODE) == O_fooONLY. Per (long standing) bug + report from Chapman Flack. + (close_redir): Change final conditional to just (status != 0) + so that ERRNO always set; the warning had its own `if (do_lint)' + anyway. + * eval.c (do_split): Force type of array to be Node_var_array + instead of Node_var. Per (long standing) bug report from + Chapman Flack. + +Thu Jul 11 22:17:14 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * Makefile.in (install): Added symlink of gawk to awk if + no awk in $(bindir). + (LN_S): New variable for symlinking. + (uninstall): Remove awk if it's the same gawk. + * Configure.in: Added call to AC_PROG_LN_S for Makefile.in. + +Sun Jul 7 15:47:13 1996 Arnold D. Robbins <arnold@infographix.com> + + * main.c (main): Made `--posix' turn on interval expressions. + Gawk now matches its documentation. (What a concept!) + +Wed Jul 3 15:02:48 1996 Arnold D. Robbins <arnold@infographix.com> + + * regex.h, regex.c: Upgraded to changes from Emacs 19.31. + +Fri May 17 08:46:07 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * io.c (get_a_record): Added `continued' flag. Fix from + Darrell Hankerson for when RS = "\n|something". + +Wed May 15 02:34:55 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * Makefile.in (awklib/all): Now depends on gawk, fixes problem + with parallel make. + +Tue May 14 15:02:52 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (format_tree): Fix handling of '*' to deal with + negative value for fieldwidth -- make positive and turn on + left justify. Per bug report from Michael Brennan. + +Sun May 12 20:42:06 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * eval.c (r_get_lhs): case Node_subscript. Check if array name + is actually a function, fatal error if so. + +Sun May 5 10:11:52 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * io.c (redirect): Call flush_io() before creating a new output pipe, + per bug report from Brian Kernighan (bwk@research.bell-labs.com). + +Fri Mar 15 06:38:33 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * Makefile.in (install): Use $(INSTALL_PROGRAM), not $(INSTALL). + (local-distclean): Add `*~' to list of files to be removed. + (CFLAGS): Now contains just @CFLAGS@. + (COMPFLAGS): Replaces use of CFLAGS, has CFLAGS plus all the + other stuff. + +Wed Mar 13 14:19:38 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * io.c (mmap_get_record): Fixed to not place sentinel at end + of mmap'ed object. Won't work if file is exact multiple of + disk block size. See comments in code for more info. + Thanks to Rick Adams (rick@uunet.uu.net) for help in testing. + +Sun Mar 10 22:50:23 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * io.c (do_close): Notice if we were called as `close(FILENAME)' + and arrange to close the current input file. This turns out + to be easy to do, just call `nextfile(TRUE)'. Based on bug report + from Pascal A. Dupuis, <dupuis@lei.ucl.ac.be>. + +Thu Mar 7 08:08:51 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * field.c (init_fields, grow_fields, set_field, rebuild_record): + Nuke the `nodes' array everywhere. Anytime a field is unref'ed, + allocate a new node that is a copy of Nnull_string. This avoids + subtle memory management problems when doing a lot of assignment + to fields, and tweaking of NF. Make sure that fields_arr[0] always + has a type of Node_val! + * field.c (set_NF): If NF is decremented, clear fields between + NF and parse_high_water, otherwise if NF incremented, clear + fields between parse_high_water and NF. + * eval.c (nodetype2str): New function, used for diagnostics. + (interpret): Use nodetype2str when finding invalid node. + +Mon Mar 4 09:02:28 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (do_toupper, do_tolower): Use isascii along with + isupper/islower before changing case, in case characters have + the high bit set. This is a hack. + +Mon Feb 26 22:24:44 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (sub_common): If no match, and called from gensub, + don't free the temporary string, since the tmp_number then + writes over it. + +Sun Feb 25 23:13:01 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (format_tree): Fixed %c to treat user input as + numeric also by adding test for MAYBE_NUM. + +Tue Feb 20 12:25:50 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * configure.in: Added AC_FUNC_MMAP call and add madvise to + list of functions to look for. + * awk.h [IOP_ISMAPPED]: New flag value for mmap support and new + `getrec' structure member in struct iobuf. + * io.c (iop_alloc, iop_close): Changed to map/unmap input file + into memory if possible. + (mmap_get_record): New function to actually retrieve the + record from mmaped file. + +Thu Feb 1 08:56:46 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (do_substr): Fixed lint message to use indx+1 when + start position is past end of string. + +Sun Jan 28 07:00:56 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (do_substr): Rationalized handling of missing length + argument, as well as various accompanying lint warnings. Previous + code was slightly bogus. Talk about your Day 1 bugs. + +Thu Jan 25 14:09:11 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * builtin.c (do_substr): If length exceeds length of actual + string, do computation of needed substring length *after* + the lint warning. + +Wed Jan 24 10:06:16 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * Makefile.in (gawk): Add $(CFLAGS) to link line. + (Makefile): Target depends on the Makefile.in files. + (OTHERS): Added TAGS and tags to the distribution. + (local-distclean): New rule. + (distclean): Use it. + (maintainer-clean): Don't `make distclean' before running submakes, + since that removes makefiles needed for the submakes. + * builtin.c (do_strftime): Remove hard coded limit on length of result. + Based on code from Paul Eggert (eggert@twinsun.com). + +Mon Jan 22 13:16:37 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * main.c (usage): Takes new fp parameter which is either + stdout for `--help' (per the GNU Coding Standards) or stderr + if an error occurs. Fix all calls. + (version): Prints to stdout per the coding stds. + (copyleft): Prints to stdout now, not stderr, and exits. + +Fri Jan 19 08:10:29 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * regex.h [RE_GNU_AWK]: Added RE_CONTEXT_INDEP_OPS to set of + bits we turn off for regular operation. Breaks things like + /^+[0-9]+/ to match a literal `+' at the beginning of, say, + a phone number. + +Wed Jan 10 23:19:36 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * 3.0.0 polished up and release tar file made. + +Wed Dec 27 11:46:16 1995 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * 2.94.0 released to porting group (no, I haven't been good + about this file; I'll do better once 3.0 is released). + +Mon Aug 28 23:04:30 1995 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * awk.h updated for NeXT - bracket TRUE/FALSE + * io.c (get_a_record): Removed shadowing of 'start' in + * Makefile.in and doc/Makefile.in: Fixed to use gawk.1 and gawk.texi, + instead of gawk.1.in and gawk.texi.in. + +Mon Aug 25 11:04:30 1995 Arnold D. Robbins <arnold@skeeve.atl.ga.us> + + * 2.90.0 released to porting group. + +Fri Aug 18 12:43:31 1995 Arnold D. Robbins <arnold@puny.ssc.com> + + * ChangeLog created. |
