Raw Blame History

Mon Jul 7 11:01:43 2003 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.1.3: Release tar file made.
Mon Jul 7 09:55:49 2003 Arnold D. Robbins <arnold@skeeve.com>
* main.c (copyleft, usage): Make sure to fflush output fp. Per Jim
Meyering, if error, exit non-zero.
* ext.c (get_argument): Fix array paramater handling.
2003-07-06 Paul Eggert <eggert@twinsun.com>
* builtin.c (do_substr): Issue better diagnostics when
d_substr and d_length are NaN, or when 0 < d_length < 1.
Be careful when comparing double to SIZE_MAX, as
the comparison might return the "wrong" answer when
(double) SIZE_MAX is a number that is not equal to
SIZE_MAX.
(do_gensub): Watch out for HOW values that are out of range
or are NaN.
(do_dcngettext): dcngettext wants an argument of type
unsigned long, not long, so use a value of that type.
Fri Jul 4 10:58:02 2003 Arnold D. Robbins <arnold@skeeve.com>
* main.c (main): Make option letter 'D' fall through into default
unknown case if not debugging. Let's us have just one version of
`optlist'.
Thu Jun 26 15:25:57 2003 Arnold D. Robbins <arnold@skeeve.com>
* array.c (get_actual): Undo Stepan Kasal change of 2003-06-17.
See test/match2.awk.
Wed Jun 25 15:26:08 2003 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (do_rand): Change calculation so that result
obeys constraint: 0 <= N < 1. This is per history and POSIX.
Thanks to Nelson Beebe (beebe@math.utah.edu) for reporting
this issue.
Mon Jun 23 15:13:39 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (rs1scan): Per advice from Bruno Haible, it's safe
to skip the multibyte checking code if RS is '\n'. See
the comment in the code. Big performance improvement for
multibyte locales.
2003-06-20 Stepan Kasal <kasal@ucw.cz>
* eval.c (comp_func): if memcmp returns 0, we have to compare
the lengths.
2003-06-19 Stepan Kasal <kasal@ucw.cz>
* eval.c (interpret) <Node_K_arrayfor>: use NULL, not 0, to
initialize the variable list.
(comp_func): array indices no longer are string values,
you have to use ahname_str, ahname_len.
Tue Jun 17 11:53:46 2003 Arnold D. Robbins <arnold@skeeve.com>
* array.c (get_actual): Make check for isparam
smarter: also check for FUNC flag.
2003-06-17 Stepan Kasal <kasal@ucw.cz>
* array.c (get_actual): even if canfatal is FALSE, don't
tolerate existence of things which can't happen.
Mon Jun 16 16:21:44 2003 Arnold D. Robbins <arnold@skeeve.com>
* configure.ac: Removed m4/Makefile.
* m4/Makefile.am: Removed.
2003-06-16 gettextize <bug-gnu-gettext@gnu.org>
* configure.ac (AC_OUTPUT): Add m4/Makefile.
(AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
Sun Jun 15 20:45:43 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (get_a_record): Enhance logic to fill buffers to include
`|| no_data_left(iop)'.
(rs1scan): Fix logic for setting recm fields for multibyte
character case.
2003-06-10 Stepan Kasal <kasal@ucw.cz>
* awkgram.y (release_all_vars): do not try to release a value of
Node_var_new; after get_lhs, use the lhs directly, do not try
to do (*lhs)->var_value; the Node_var case doesn't need
special treatment.
* builtin.c (do_match): `get_param' is successful iff it returns
Node_var_array---if the variable was new, get_param has already
changed the type.
* field.c (do_split): likewise.
Sun Jun 15 19:36:35 2003 Arnold D. Robbins <arnold@skeeve.com>
* node.c (r_dupnode): Typo fix in hash tables: stptr -> ahname_str.
Thanks to mary1john8@earthlink.net.
* array.c (get_actual): Add `if (canfatal)' before call to
`cant_happen'.
Sun Jun 15 19:25:49 2003 Patrick T.J. McPhee <ptjm@interlog.com>
* awk.h (memcpy_ulong): Add ! WIN32 to ifdefs.
Mon Jun 9 18:38:20 2003 Arnold D. Robbins <arnold@skeeve.com>
* custom.h (hpux): Added stuff to (hopefully) get `tzset'
declared on HP/UX 10 and up.
Mon Jun 9 17:12:24 2003 Patrick T.J. McPhee <ptjm@interlog.com>
* awk.h (ATTRIBUTE_EXPORTED): New macro for dynamic libs on Windows32.
* CONVMFTidx, stack_ptr, do_lint, lintfunc: Now have this attribute.
Mon Jun 9 13:11:33 2003 Arnold D. Robbins <arnold@skeeve.com>
Clean up of Stepan's patches.
* array.c (get_actual): Renamed from r_get_array. Added second
param canfatal if routine should print fatal message when not an array.
(get_actual): Renamed 'prm' to `isparam'.
(array_vname): Add static msglen var; only realloc string if it grows.
Don't use `s += sprintf(...)'. No good on old systems where sprintf
returns char *. Minor formatting cleanups.
(do_adump): Restored separate `a' and `r' variables; helps for debugging.
* awk.h (SCALAR, UNINITIALIZED): Removed entirely, renumbered other flags.
(get_array, get_param): New macros, calls get_actual.
(get_actual): Declaration changed from that of r_get_array.
* awkgram.y (release_all_vars): Restored previous version of code; new
version isn't right for Node_xx variables.
(variable): Minor code cleanup for readability.
* builtin.c (do_match): Use get_param and print our own message when
third parameter is not an array.
* eval.c: Added a few comments here and there, removed some no longer
needed comments.
* field.c (do_split): Use get_param and print our own message when
second parameter is not an array.
Mon Jun 9 11:46:21 2003 Arnold D. Robbins <arnold@skeeve.com>
* array.c (do_delete): Initialize hash1 and last to keep gcc -Wall happy.
* io.c (rsnullscan): Comment out label skip_leading for same reason.
Wed May 28 08:31:23 CEST 2003 Stepan Kasal <kasal@math.cas.cz>
* eval.c (forloops_active, in_function): Nuked.
(pop_all_forloops, pop_fcall_stack): are now inline.
Wed May 28 07:58:35 2003 Stepan Kasal <kasal@math.cas.cz>
* field.c, awk.h (Null_field): no longer static.
* field.c (init_fields): initial value of $0 can be Nnull_string,
no need to copy it.
* eval.c (r_get_lhs) <Node_field_spec>: test for uninitialized field,
which is Nnull_string for $0 and Null_field for $(>0).
* builtin.c (do_print_rec): test for uninitialized $0.
Tue May 27 17:03:02 2003 Stepan Kasal <kasal@math.cas.cz>
* awk.h (Node_var_new): New node type for variables which can be
either scalar or array. From now on, Node_var is always scalar.
(Node_gvar_ref): Nuked, its role can be taken by Node_array_ref.
(orig_var): removed, orig_array is enough.
(SCALAR, UNINITIALIZED): Flags nuked.
(var_uninitialized): new macro to distinguish uninitialized vars;
used in several other macros.
* array.c (r_get_array, array_vname, do_adump): adapt to the
above changes.
* awkgram.y, eval.c, field.c, main.c, node.c, profile.c: ditto.
Tue May 27 14:27:50 2003 Stepan Kasal <kasal@math.cas.cz>
* array.c (r_get_array): New function, which goes all the way
through Node_param_list to actual Node_var_array; if it encounters
non scalar Node_var, it changes it to Node_var_array.
(in_array, do_delete, do_delete_loop, do_adump, assoc_sort_inplace):
Use get_array.
(assoc_lookup): The parameter must be a Node_var_array.
* awk.h (get_array, r_get_array): Declare the new function and define
a macro to speed it up.
* builtin.c (do_match): Use get_array.
* eval.c (interpret) <Node_K_arrayfor>: ditto.
(r_get_lhs) <Node_K_arrayfor>: ditto.
* field.c (do_split): ditto.
Tue May 27 08:23:51 2003 Stepan Kasal <kasal@math.cas.cz>
Changed node->vname meaning for type Node_array_ref and Node_gvar_ref.
It contains only the reference name; one has to (recursively) follow
node->prev_array to find out the call history for the array.
* array.c (array_vname): New function to print the array name.
(assoc_lookup, do_delete): Use array_vname.
* eval.c (interpret, r_tree_eval, r_get_lhs): Use array_vname.
(push_args, pop_fcall): Things have simplified.
* awk.h (array_vname): Declare.
(prev_array): Define.
Sun Jun 8 11:25:36 2003 Stepan Kasal <kasal@ucw.cz>
* awkgram.y (append_right): when using savetail, remember that it
is not necessarily the tail of the list---it's just a pointer to
the last chunk appended.
Thu Jun 5 12:01:41 2003 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (do_strtonum): Make `strtonum(13)' work.
Wed Jun 4 17:07:06 2003 Corinna Vinschen <vinschen@redhat.com>
* io.c (binmode): Include function for __CYGWIN__ too.
Tue Jun 3 12:40:50 2003 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (interpret): Node_K_switch. For regex case, don't
call `free_temp' on the result of `force_string' if it's equal to
switch_value. Thanks to John DuBois <spcecdt@armory.com>
for finding the problem.
Sun Jun 1 13:08:22 2003 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (format_tree): For %c, force precision to 1.
Wed May 28 11:55:48 2003 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (isnoeffect, isassignable): Add Node_TEXTDOMAIN to
switches in both functions.
Wed May 28 11:38:59 2003 Stepan Kasal <kasal@math.cas.cz>
* awkgram.y (switch_body): remove rule ``switch_body:/*empty/''
as ``switch_body:case_statements'' covers it---this disambiguation
fixes a reduce/reduce conflict.
Sun May 25 16:23:43 2003 Corinna Vinschen <vinschen@redhat.com>
* configure.ac: Remove linking against /usr/lib/automode.o.
* configure: Regenerate.
Sun May 25 15:19:19 2003 Stepan Kasal <kasal@math.cas.cz>
* awk.h (get_lhs): For an initialized Node_var, you may return
the address of var_value pointer, no matter whether reference
bit was set or not. We were silly slowing down most of the
assignements.
* (get_a_record): after grow_iop_buffer, move recm.rt_start even
if recm.len == 0.
Mon May 19 16:55:59 2003 Arnold D. Robbins <arnold@skeeve.com>
Code for C-style switch statements. Initial version contributed by
Michael Benzinger <Michael.Benzinger@sabre-holdings.com>.
Disabled by default, use `configure --enable-switch' to turn it on.
* configure.ac: New AC_ARG_ENABLE for switch statements.
* awk.h (NODETYPE): New types for switch, case, default keywords
and respective lists.
* awkgram.y: New productions for switch statement. Does checking to
avoid duplicate cases.
* eval.c (nodetypes): New entries for new NODETYPEs.

Sun May 18 12:03:56 2003 Arnold D. Robbins <arnold@skeeve.com>
* array.c (do_delete_loop): Fix bracing of logic for
tests.
Wed May 14 09:01:16 2003 Stepan Kasal <kasal@math.cas.cz>
Misc patches:
* builtin.c (do_match): if third parameter to `match' is supplied,
store all subexpressions which are applicable, even though there
are some unused between them.
* awkgram.y (yylex): when returning from unterminated REGEXP
(which is /* kludge */), take care to fake a yylval, to
prevent ``internal error'' later.
Sun May 11 15:51:00 2003 Stepan Kasal <kasal@math.cas.cz>
* io.c (rsnullscan, get_a_record): Boundary condition bug fixes.
Sun May 11 15:15:20 IDT 2003 Scott Deifik <scottd@amgen.com>
* awk.h: Add decls for `memcpy_ulong', `memset_ulong', and
MSC defines.
* regex.c: Include <stdio.h> if MSC for size_t.
Mon May 5 15:11:06 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (get_a_record): Only tweak RT's value in place if the current
RS scanner is the same as the last one. Bug report submitted by
John DuBois (<spcecdt@armory.com>).
Fri May 2 14:39:48 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (get_a_record): Add logic at end to be smart about setting
RT. Saves considerable time, esp for default case where RS = "\n".
Wed Apr 30 11:44:38 2003 Arnold D. Robbins <arnold@skeeve.com>
* field.c (do_split): Add check and code for Node_gvar_ref.
* array.c (in_array, do_delete, asort_actual): Same.
* builtin.c (do_split): Same for 3rd arg array parameter.
* eval.c (interpret): Same for Node_K_array_for.
(push_args): Same for evaluating extra args.
Tue Apr 29 15:54:28 2003 Arnold D. Robbins <arnold@skeeve.com>
Record reading code redone/simplified considerably.
* awk.h (IOBUF): Removed total field, no longer used.
* io.c (at_eof, has_data, no_data_left): New macros.
(RECVALUE, SCANSTATE): New enumerated types.
(rs1get_a_record, rsnull_get_a_record, rsre_get_a_record): Removed.
(get_a_record): Rewritten, again. Now contains just buffer and
record code; searching code moved into these functions:
(rs1scan, rsnullscan, rsrescan): New functions to scan a buffer
for record contents and terminator. Fill in values in:
(struct recmatch): Holds found record and terminator.
(spec_setup): Set iop->dataend to indicate data is already in buffer.
(nextfile, inrec): Use new macros instead of flag and pointer tests.
(set_RS): Set scanning function instead of record function.
FWIW, it all passes `make test'.
Sun Apr 27 21:02:39 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (do_close): At end, if do_posix return 0. See comment in code.
Tue Apr 15 09:56:03 2003 Isamu Hasegawa <isamu@yamato.ibm.com>
* configure.in: Check existence of wcrtomb, and wcscoll.
* configh.in: Likewise.
* configure: Re-generate.
Thanks to Kimura Koichi <kimura.koichi@canon.co.jp> for reporting.
Sun Apr 13 16:02:10 2003 Arnold D. Robbins <arnold@skeeve.com>
* main.c (main): Add call to `setlocale' for LC_NUMERIC after program is
parsed.
(arg_assign): Switch back to "C" locale for LC_NUMERIC for command
line assignments; this is per POSIX that period is decimal point for
program and command line assignments and the locale's separator
applies for input, output, and string to number conversion.
2003-03-26 Paul Eggert <eggert@twinsun.com>
* builtin.c [HAVE_INTTYPES_H]: Include <inttypes.h>.
[!HAVE_INTTYPES_H && HAVE_STDINT_H]: Include <stdint.h>.
(CHAR_BIT, INTMAX_MIN, UINTMAX_MAX): Define if the system does not.
(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): New macros, taken from
coreutils and many other GNU utilities.
(format_tree): When formatting, use widest possible integers
rather than settling with 'long'.
(do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Likewise,
when doing bitwise operations.
* configure.in (jm_AC_TYPE_LONG_LONG, jm_AC_TYPE_UNSIGNED_LONG_LONG,
jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Add, since the mainline
code now needs this.
* doc/gawk.texi (Control Letters, Bitwise Functions): Document this.
* m4/intmax_t.m4: New file, taken from coreutils (but renamed to
avoid collision with our m4/inttypes.m4).
* m4/longlong.m4: New file, taken from coreutils.
* m4/uintmax_t.m4, m4/ulonglong.m4: Remove; superseded by the above
new m4 files.
* builtin.c (BITS_PER_BYTE): Remove; use CHAR_BIT instead, since
it's the standard name.
(do_lshift, do_rshift): Complain if the shift width is exactly equal
to the word size, too.
Thu Mar 27 10:44:11 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
Enhance check for no data left in file to be only if file has
non-zero size. Linux files such as /proc/filesystems stat as a
regular file of size 0, but actually have contents. Ugh.
Thanks to Martin Schlemmer <azarah@gentoo.org> for the bug report.
Wed Mar 26 12:19:32 2003 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (format_tree): Add a lint warning at label `out_of_range'.
Tue Mar 25 12:24:38 2003 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (variable): For array subscript, if NAME is in the
symbol table, but not a variable, array, or parameter, generate
a syntax error.
(isarray): New function, tests if a symbol can be an array.
* custom.h: Add check for HP/UX, needed for GCC.
Mon Mar 17 09:21:09 2003 Arnold D. Robbins <arnold@skeeve.com>
Allow simultaneous manipulation of a global array directly
and when passed as a parameter.
* awk.h (Node_gvar_ref): New nodetype.
[orig_var]: New macro.
* array.c (do_delete_loop, do_delete): Add logic to handle
seeing Node_gvar_ref.
* eval.c (nodetypes): Add Node_gvar_ref.
(r_tree_eval, r_get_lhs): Add Node_gvar_ref case.
Wed Mar 19 14:10:31 2003 Arnold D. Robbins <arnold@skeeve.com>
This time for sure.
-- Bullwinkle
* Release 3.1.2: Release tar file made.
Wed Mar 19 14:08:11 2003 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y: Production `program --> program error'. Add a return so
that we don't produce an infinite stream of error messages.
Thanks to Michael Mauch <michael.mauch@gmx.de> for pointing this out.
Wed Mar 19 13:45:50 2003 Corinna Vinschen <vinschen@redhat.com>
* regex.c [RE_ENBABLE_I18N]: remove definition; the one in
regex_internal.h is better and makes things work with Cygwin.
Tue Mar 11 11:54:20 2003 Arnold D. Robbins <arnold@skeeve.com>
* regex_internal.h: Don't include <limits.h> after <regex.h> was
included in regex.c, since it could redefine RE_DUP_MAX to a lower
value.
(bitset_set, bitset_clear, bitset_contain): Use 1UL instead of 1 in
left shift operations.
* regex.c: Include <limits.h> before <regex.h>
* regcomp.c (re_compile_fastmap_iter, init_word_char, parse_expression):
Use 1UL instead of 1 in left shift operations.
Mon Mar 10 15:45:37 2003 Corinna Vinschen <vinschen@redhat.com>
* configure.in: Update CYGWIN case to add /usr/lib/automode.o.
Thu Mar 6 11:07:36 2003 Arnold D. Robbins <arnold@skeeve.com>
Updated to automake 1.7.3.
* config.guess, config.sub: Updated from prep.
* Makefile.am (AUTOMAKE_OPTIONS): Add dist-bzip2 to get .bz2 files.
Tue Mar 4 10:40:46 2003 Arnold D. Robbins <arnold@skeeve.com>
* version.in: Added goop for K&R compilers; forgot that I have to fix
this file which then is used to create version.c.
Mon Mar 3 17:00:44 2003 Arnold D. Robbins <arnold@skeeve.com>
* configure.in: New option --disable-lint.
* awk.h (do_lint, do_lint_old): Conditionally declare based on NO_LINT.
* eval.c (set_LINT): Ifdef out body if NO_LINT.
* main.c (do_lint, do_lint_old): Conditionally compile properly.
(main): Handle --lint argument code.
Fri Feb 28 10:43:07 2003 Arnold D. Robbins <arnold@skeeve.com>
* main.c (main): Add LC_TIME to the things that get set with
setlocale().
* builtin.c (format_tree): Change test of `n0-- <= 0' to ==, avoids
VMS diagnostic.
Thu Feb 27 17:48:29 2003 Pat Rankin <rankin@pactechdata.com>
* regexec.c (proceed_next_node): Cast re_string_get_buffer to char *.
(get_subexp): Likewise.
Tue Feb 25 12:33:41 2003 Arnold D. Robbins <arnold@skeeve.com>
* regex_internal.h, regex_internal.c, regcomp.c, regexec.c:
Make MB_CUR_MAX into thread local variable re_mb_cur_max.
Unrelated, from Scott Deifik:
* io.c (grow_iop_buffer): Add checks for overflow of new buffer size.
Mon Feb 24 13:30:59 2003 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (gawk_mb_cur_max): Declared:
* main.c (gawk_mb_cur_max): Defined, init to 1.
(main): Initialize gawk_mb_cur_max.
* awkgram.y, builtin.c, eval.c, field.c, io.c, re.c (mb_cur_max):
Replaces all instances of MB_CUR_MAX, which is a function call (!)
in glibc. Big speed up, especially for -Fx case, where x is a
single character.
Unrelated:
* awkgram.y (rule): For non-existent action, use a Node_K_print_rec
node.
Sun Feb 23 15:45:20 2003 Arnold D. Robbins <arnold@skeeve.com>
Speed up plain `print' and `print $0':
* awk.h (Node_K_print_rec): New node type.
(do_print_rec): Declare function.
* awkgram.y (simple_stmt): Create humongous test for plain `print'
or `print $0', and if so, use a Node_K_print_rec for it. Modify
test for lint message.
* builtin.c (redirect_to_fp): New function for common code to get fp
and rp for do_print{,f,_rec} functions.
(do_print): Use redirect_to_fp().
(do_printf): Use redirect_to_fp().
(do_print_rec): New function to just print $0 from field_arr[0]
directly; will rebuild the record first if necessary.
* eval.c (nodetypes): Add Node_K_print_rec.
(interpret): Add Node_K_print_rec case.
* profile.c (pprint): Add Node_K_print_rec case.
(pp_print_stmt): If null lnode, print "$0" else print the lnode.
Unrelated:
* regex_internal.h: Add ENABLE_NLS to the condition for using
gettext so that --disable-nls really disables it.
Sat Feb 23 22:46:00 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
Modify buffer-filling algorithm to always read one or more multiples
of the blocksize (iop->readsize).
(grow_iop_buffer): Make sure there's room for the current partially
read record and one disk block buffer.
Thu Feb 20 22:02:00 2003 Arnold D. Robbins <arnold@skeeve.com>
* re.c (research): Fix typo in cast of precision value to int.
* regex.h, regex.c, re_internal.h, re_internal.c, regcomp.c, regexec.c:
synced to GLIBC source, maintaining K&R portability changes, and bug
fixes, although losing ability to compile each file separately.
* Makefile.am (SOURCES): Moved placement of regex source files from here ...
(EXTRA_DIST): ... to here.
Tue Feb 18 14:17:33 2003 Arnold D. Robbins <arnold@skeeve.com>
* re.c (research): Cast precision value to int.
* builtin.c (format_tree): For toofew, cast field width value to int.
* io.c (rsre_get_a_record): Initialize restart and reend. Add a variable
to make sure they're set before used at end of function.
(iopflags2str): Removed decl at top and made not static so that GCC
stops complaining that it's defined but not used. Bleah.
Mon Feb 17 11:02:34 2003 Arnold D. Robbins <arnold@skeeve.com>
* config.guess, config.sub: Updated from prep.
Sun Feb 16 15:47:15 2003 Scott Deifik <scottd@amgen.com>
* awk.h (format_tree, make_str_node): Changed decls to match how
they are called.

* regex.h: Ditto.
Tue Feb 4 13:39:37 2003 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (builtin_func): New string for use in rationalizing
function parsing and installation code.
Sun Feb 2 16:00:55 2003 Arnold D. Robbins <arnold@skeeve.com>
Cache function body code pointer so that only have to find it the
first time a function is called. This potential for optimization
brought to my attention by Stepan Kasal.
* awk.h [funcbody]: New macro.
* awkgram.y (FUNC_CALL): Set $$->funcbody to NULL.
* eval.c (func_call): Changed to take top-level Node_func_call as the

* profile.c (pp_func_call): Similar changes.
(tree_eval): Ditto.
Sun Feb 2 15:32:42 2003 Stepan Kasal <kasal@math.cas.cz>
ADR: More grammar rationalization/repair from Stepan.
* awkgram.y (common_exp, simp_exp): the rule from getline (without
pipe) has been moved from common_exp to simp_exp.
The redirection of print statements reworked. The idea comes from
mawk-1.3.3; much thanks to Michael Brennan!
* awkgram.y (IO_OUT, IO_IN): new tokens.
(APPEND_OP, TWOWAYIO): swallowed by the above ones.
(in_print, in_parens): new static variables, to trace whether
IO_OUT is expected.

(exp): the print command(s) reworked.
(oputput_redir): reworked.
(print_expression_list): new non-terminal.
(rexp, rexpression_list opt_rexpression_list): nuked.
(exp, simp_exp): ``cmd|getline'' rule changed to
``cmd IO_IN getline'' and moved from exp to simp_exp.
Unrelated:
* awkgram.y (variable): Don't return Node_func, issue a fatal
error instead.

* field.c (do_split): The third argument to split(), sep, has to be
evaluated and the result dupnoded before assoc_clear is called,
similarily as src. And we needn't to evaluate the third argument
if it's CONSTant regex and the first parameter is null string.
* awk.h (dupnode): Changed to macro, function renamed to r_dupnode.
* node.c (dupnode, r_dupnode): Rename.
* awkgram.y (parms_shadow): Return bool value, ...
(shadow_funcs): ... which will enable us to end the program if
lintfunc is fatal.
(program): Cleanup of the rules defining the ``program'' non-terminal.
(start, program, rule): no value associated,
expression_value is now treated similarily as begin_block and end_block.
(pattern, rule): bison actions for non-terminal `pattern' now
add a new rule to the appropriate Node_rule_list, action for
non-terminal `rule' now only adds the associated code block
to the rnode of Node_rule_node.
(io_allowed): renamed to !begin_or_end_rule.
(append_pattern): New function, adds new Node_rule_node to a rule_list.
(mkrangenode): Deleted, this tiny function was called only once.
(function_body): non-terminal replaced by `action'.
(statements, action, statement): `statements' can now be empty;
both callers had to accomodate to this.
(statements): Don't call isnoeffect($2->type) if
$2 happens to be NULL.
Mon Jan 27 14:12:19 2003 Arnold D. Robbins <arnold@skeeve.com>
* io.c (iop_close): Based on report by Stepan Kasal and because of
his changes, don't call reset_record() when saving a copy of contents
of $0.

report by Stepan Kasal.
Mon Jan 27 14:06:20 2003 Stepan Kasal <kasal@math.cas.cz>

on some systems. Replaced on all spots where it was used.
Sun Jan 26 11:52:01 2003 Arnold D. Robbins <arnold@skeeve.com>
* awk.h [NUMSUBPATS]: New macro.
* builtin.c (do_match): Use it in loop that fills in subpattern info.
* eval.c (r_tree_eval): for Node_assign, don't call free_temp(),
as assign_val() contains dupnode(), which would clear the TEMP
flag. From Stepan Kasal <kasal@math.cas.cz>.
* config.sub: Updated from prep.
Sun Jan 19 22:34:01 2003 Arnold D. Robbins <arnold@skeeve.com>

* awkgram.y (tokentab): Add asorti() function to table.
* array.c (ASORT_TYPE): New enumerated type for VALUE or INDEX array
sorting.
(assoc_sort_inplace): New second arg of type ASORT_TYPE. Additional code
to rearrange array so rest of merge-sorting works; basically values are
tossed and index moved into value spot.

(do_asort): Calls asort_actual(tree, VALUE).
(do_asorti): Calls asort_actual(tree, INDEX).

compilation of the reg*c files.
* regcomp.c: Fix bug in using translation tables with [[:upper:]] etc.
* Makefile.am: Move regex files into sources from EXTRA_DIST. (ADR)
Mon Dec 9 14:20:42 2002 Stepan Kasal <kasal@math.cas.cz>
* main.c (main): When processing option '-f' don't ignore spaces
if optarg points at the beginning of the current argument
(like ``gawk -f " " file'').
2002-11-30 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>

Sun Nov 24 18:23:29 2002 Arnold D. Robbins <arnold@skeeve.com>
From Paul Eggert, with some edits by me.
* builtin.c (do_substr): Consistently use floating point
values for lint messages, so they should be printed pretty
much as the user saw them. Check for overflow before
converting floating point to integer. Do the right thing with
NaNs.
Check for index out-of-range before checking for length
out-of-range, to avoid some nasty effects if address
arithmetic overflows (e.g., indx + length < index).
Allow zero-length substrings when checking for lint if
do_lint == LINT_INVALID.
Sun Nov 24 18:21:06 2002 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (LINT_ALL, LINT_INVALID): New constants.

work for GCC 3.2 and later.
* io.c (PIPES_SIMULATED): Don't define if on AIX, which
does define TANDEM in one of its header files. Ugh.

* builtin.c (do_substr): Use %lu in warnings instead of %d.
Mon Nov 18 14:42:53 2002 Arnold D. Robbins <arnold@skeeve.com>

* eval.c (r_get_lhs): For variables, always clear UNINITIALIZED,
since the variable is about to be assigned to. From Stepan Kasal.
Fri Nov 1 11:19:01 2002 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (lintfunc): Can only supply attributes for a function
pointer if GCC >= 3. Added ifdefs. Bah, humbug.

Mon Oct 28 16:35:39 2002 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (hash): Now a function pointer.
* array.c (gst_hash_string, scramble): New functions.
(awk_hash): Renamed from hash.
(hash): Now a function pointer.
(array_init): Change hash function based on environment for
experimentation.
Mon Oct 28 13:21:20 2002 Arnold D. Robbins <arnold@skeeve.com>
Applied lots of patches from Stepan Kasal, tweaked as needed
for current code base.
* node.c (dupnode): When n->stref overfows, flag the node as PERM.
Same for n->ahname_ref.
(unref): Remove the check for n->stref == LONG_MAX and
n->ahname_ref == LONG_MAX.
* awk.h (make_string): The third argument to make_str_node changed
from FALSE to 0, it's not Boolean.
(free_temp): Evaluate the argument only once, so that we
can call free_temp(tree_eval(n)) for achieving side effects.
(load_environ, load_procinfo): Changed return type to NODE *.
* main.c (load_environ): The ENVIRON_node should be created with type
Node_var_array and lnode set to NULL. Return pointer to the created node
and create an empty hash even on TANDEM.
(load_procinfo): Same mods for PROCINFO_node.
(init_args): ARGV_node should also have lnode set to NULL.
* eval.c (r_tree_eval): case Node_assign moved just above the other
assignment cases.
(op_assign): ++ and -- cases merged with += and -=, respectively.
(push_args): Evaluate all args, even in cases where more args are
supplied then required.
(interpret): In case Node_K_forarray, flag the variable
num_elems also as volatile, so that it survives longjmp() and
can be trusted when linting code.
(r_get_lhs): Case Node_param_list was unreachable (unless
something breaks really badly), remove it;
(r_tree_eval): case Node_var_array removed from the last switch,
it was caught in the first switch above.
* profile.c (tree_eval): Again, case Node_var_array was caught above.
* awkgram.y (variable): Code simplified, making use of the above
changes.
* field.c (sc_parse_field): IGNORECASE only applies to regex based
field-splitting, so remove code that pays attention to it.
(do_split): Don't use parse_field if RS_is_null.
(set_FS): Beware of FS == "\\" even if RS_is_null.
Code changes to make things work better:
* field.c (set_FS): Don't use cmp_nodes() to compare old and new
value of FS, that uses IGNORECASE, which is a bad idea. Improve
logic for choosing sc_parse_field. Ensure that when RS_is_null
but using a single character, that we do pay attention to
case when doing regex splitting.
* io.c (set_RS): Don't use cmp_nodes() to compare old and new
value of RS, that uses IGNORECASE, which is a bad idea.
Mon Oct 28 09:43:14 2002 Arnold D. Robbins <arnold@skeeve.com>
* recomp.c (parse_expression): Change return statement into
two so it'll compile for SGI cc.
* awk.h (STR, CUR): Changed to STRCUR and NUMCUR respectively,
to avoid conflict with STR on some System V systems. Changed
in all source files.
Thu Oct 24 16:14:34 2002 Arnold D. Robbins <arnold@skeeve.com>
* array.c (AVG_CHAIN_MAX): Now a variable, to allow easy experimentation.
(array_init): Pulls a new value from env var AVG_CHAIN_MAX if it
exists and sets the variable.
* awk.h: Add declaration for array_init().
* main.c (main): Call array_init().
Tue Oct 22 11:23:56 2002 Arnold D. Robbins <arnold@skeeve.com>

* builtin.c (tolower, toupper): Add casts to char* to fix some
compiler warnings.
* eval.c (cmp_nodes): Ditto.
* regcomp.c (peek_token_bracket): Skip the byte already read.
Wed Oct 16 15:02:09 2002 Arnold D. Robbins <arnold@skeeve.com>
* io.c (set_RS): Make sure to always call set_FS().
2002-10-11 Isamu Hasegawa <isamu@yamato.ibm.com>
* regcomp.c (re_compile_fastmap_iter): Remove the handling
OP_CONTEXT_NODE.
(regfree): Likewise.
(create_initial_state): Likewise.
(analyze): Remove the substitutions which became useless.
(calc_first): Likewise.
(calc_epsdest): Use edests of OP_BACK_REF in case that it has
epsilon destination.
(duplicate_node_closure): New function.
(duplicate_node): Remove the handling OP_CONTEXT_NODE.
(calc_inveclosure): Likewise.
(calc_eclosure): Likewise.
(calc_eclosure_iter): Invoke duplicate_node_closure instead of
direct invocation of duplicate_node.
(parse): Don't use comma operator in the return to avoid compiler
warning.
(parse_reg_exp): Likewise.
(parse_branch): Likewise.
(parse_expression): Likewise.
(parse_sub_exp): Likewise.
(parse_dup_op): Likewise.
* regex_internal.c (re_dfa_add_node): Remove the substitutions
which became useless.
(create_ci_newstate): Remove the handling OP_CONTEXT_NODE.
(create_cd_newstate): Likewise.
* posix/regex_internal.h (re_token_type_t): Remove the obsolete type.
(re_token_t): Likewise.
(re_dfa_t): Likewise.
(re_node_set_remove): New macro.
* regexec.c (check_matching): Remove the handling
OP_CONTEXT_NODE.

(proceed_next_node): Likewise.
(pop_fail_stack): Fix the memory leak.
(set_regs): Likewise.
(free_fail_stack_return): New function.
(sift_states_backward): Fix the memory leak. Remove the handling
OP_CONTEXT_NODE.
(update_cur_sifted_state): Append some if clause to avoid redundant
call.
(sub_epsilon_src_nodes): Use IS_EPSILON_NODE since it might be a
back reference.

(sift_ctx_init): Add initializing.
Tue Oct 15 14:18:53 2002 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (set_IGNORECASE): Call set_RS() instead of
set_FS_if_not_FIELDWIDTHS(). The former calls the latter
for us, and also makes IGNORECASE affect RS like it's supposed to.
* field.c (FS_re_yes_case, FS_re_no_case): New variables.
(set_FS): Smarten up routine to not recompile FS_regexp if all
that's changed is IGNORECASE or if switching back to FS from
FIELDWIDTHS. Significant speed-up for cases where IGNORECASE
is assigned to for every record.
* io.c (RS_re_yes_case, RS_re_no_case): New variables.
(set_RS): Similar changes as to set_FS(). In particular,
IGNORECASE changing now affects record splitting too.
* re.c (refree): Set rp->pat.tranaslate to NULL. It comes
from casetable and shouldn't be freed. (Strictly necessary
only for old regex, but a good idea anyway).
Also, call regfree(& rp->pat) instead of manually free()ing
things, since there's dynamically allocated stuff hiding in
the buffer. Avoids a memory leak.
Mon Oct 14 12:02:39 2002 Arnold D. Robbins <arnold@skeeve.com>
Major space reduction in array management. Overhead reduced
to two NODE's per element from three.
* awk.h (ahash): Union is gone.
(hash.ref): new union member.
(ahnext): new definition into hash union.
(ahvalue): new definition into hash union.
(ahname_str): new member, points into hash union.
(ahname_len): new member, points into hash union.
(ahname_ref): new member, points into hash union.
* array.c: Replaces uses of ahname member with string and
length. Set the reference count correctly to 1 on new nodes.
* eval.c (interpret): Case for Node_K_arrayfor. dupnode() the
array indices, and set loop variable to new value made via
make_string().
* node.c (unref, dupnode): Node_ahash nodes are now also
reference counted, a la strings. Similar code is used to
increment/decrement the counts, and/or copy nodes as
needed.
Unrelated:
* awk.h (forsub): Removed. Not used.
Sun Oct 13 16:58:27 2002 Stepan Kasal <kasal@math.cas.cz>
* profile.c (pprint): #undef the temporary defines at the end
of the case.
* eval.c (interpret): Likewise.
(assign_val): we can unref() before doing dupnode().
Also, move the check for NF < 0 from here ...
* field.c (set_NF): ... to here.
* main.c (varinit): no need to call set_NF().
* awkgram.y (statements): don't be so generous when concatenating
`statements' with a `statement'.
2002-10-13 Isamu Hasegawa <isamu@yamato.ibm.com>
* regcomp.c: Synced with development sources.
* regex_internal.c: Synced with development sources.
* regex_internal.h: Synced with development sources.
* regexec.c: Synced with development sources.
Sun Oct 13 21:35:35 2002 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (NODE): reflags is now unsigned long for:
(exec_count): defined to be sub.nodep.reflags. Using `number'
broke pgawk.
* profile.c (Node_K_delete_loop): print out as a for loop
with a comment that it's internally the same as `delete array'.

Mon Jan 7 22:12:15 2002 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (statement): moved delete, print, and expressions into
new non-terminal `simple_stmt'. Allow opt_simple_stmt in the

problems on multiple platforms, and gawk doesn't even
use the routine. The heck with fine-grained solutions.
Wed Nov 14 16:12:40 2001 Pat Rankin <rankin@eql.caltech.edu>
* builtin.c (bchunk_one): Use `ofre < 1' instead of `ofre <= 0'

Tue Nov 13 17:27:52 2001 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (yyerror): Fix the code to behave like it

Apparently bisoon adds a semicolon to each body
automatically and byacc doesn't.
Sun Oct 28 16:53:18 2001 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (format_tree): Fix off-by-one error in "ran out
for this one" diagnostic. Also fix lint check for too many
arguments vs. count in format string.

* fixvers: Check that files exist before doing `cmp', in
case they're in a source code system and aren't there.
Fix from Grant Erickson (gerickson@brocade.com).
Thu Oct 4 18:20:36 2001 Arnold D. Robbins <arnold@skeeve.com>

fd > fileno(stderr).
2001-09-07 Paul Eggert <eggert@twinsun.com>

use "__sun" rather than "solaris". No compilers predefine
"solaris", but both GCC and Sun C predefine "__sun".
Thu Aug 30 15:17:12 2001 Arnold D. Robbins <arnold@skeeve.com>
* main.c (copyleft): Use a printf %d for last year of update
to avoid translation strings changing when the file
is updated from now on. Suggestion from Ulrich Drepper.
Thu Aug 23 14:01:14 2001 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (unary minus production): Add check that value
isn't a string. Based on bug report from drj@pobox.com.
* profile.c (tree_eval): For node_val, only test NUMBER
to see if value is numeric, not NUM|NUMBER.
Thu Aug 16 12:21:28 2001 Arnold D. Robbins <arnold@skeeve.com>

* po/fr.po, po/tr.fo: New files.
2001-08-13 Paul Eggert <eggert@twinsun.com>
This patch fixes a bug that causes gawk to rewind standard
input incorrectly. It also removes all instances of fseek,
from the gawk source proper, which should make gawk a bit
more portable.
(The original patch removed off_t & lseek too, but I need
that for something else. ADR.)
* posix/gawkmisc.c (optimal_bufsize):
Don't use lseek on the input, because that might change
its state. Instead, just check whether it is a regular file.

(Also, fix a spelling error in the first line of the source.)
* pc/gawkmisc.pc, unsupported/atari/gawkmisc.atr: Likewise.

Michel Jouvin <jouvin@lal.in2p3.fr>.
Wed Jul 4 18:34:19 2001 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (assign_val): Don't allow negative values for NF.
* field.c (set_NF): Robustify field-freeing code to make sure
values are always positive.
Sun Jul 1 19:15:01 2001 Arnold D. Robbins <arnold@skeeve.com>

tm_isdst member as an optional trailing integer, and to
specify "out-of-range" members. Check for overflow when
subtracting 1 from month or 1900 from year. Allow years just
past INT_MAX, as they work on some hosts when INT_MAX - 1900
is representable as an int.
* doc/gawk.1, doc/gawk.texi: Document the above changes.
Also, document that the origin-zero Gregorian calendar is used.
Fix confusing wording about "midnight" by replacing it with 00:00
("midnight" is also 24:00, the end of the day).
Mention the typical range for time stamps.
Do not assume that years are nonnegative and are less than 10,000.
Suggest TZ=UTC0 instead of TZ=GMT0, as that's how recent versions
of GNU date behave.
GMT is not always the time of day in Greenwich these days.
Fix typos: "Emporer/Era", "1980's", "1970's".
* m4/largefile.m4: Synchronized with latest version.

array indices. Creates significant problems if index is
numeric value and CONVFMT changes. Added fix to set
bucket->ahname->stfmt to -1 so that force_string never recalculates

* io.c (close_one): Added a lint warning if it becomes
necessary to start multiplexing fd's, per ancient suggestion

assoc_sort_inplace): new functions.
* eval.c (tree_eval): in debug code, make uninitialized var

code has been cleaned up to not need different values for
profiling/not profiling.

Sun Sep 27 10:18:05 1998 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (reisstring): new prototype.
* re.c (reisstring): new function, returns true if the re did
a simple string match. This is rather simplistic in its logic.
* io.c (get_a_record): in the case that RS is a regexp, AND
the re matched at the exact end of the buffer, add a call to
`reisstring' in case it's a simple string match. If so, we
don't need to read more into the buffer because we don't
have a regex like `x.*y' that might extend longer.
This should be very helpful for interactive /inet clients
where something like `RS = "\r\n"' happens.
Thu Aug 13 22:07:40 1998 Arnold D. Robbins <arnold@skeeve.com>

Tue Jun 2 15:23:05 1998 Arnold D. Robbins <arnold@skeeve.com>
* io.c (devopen): relax previous change, don't require "any",
just that a port be there. The user can put 0 if they
don't care.
Wed May 27 21:33:45 1998 Arnold D. Robbins <arnold@skeeve.com>
* io.c (devopen): for /inet, require that local and remote
ports and the remote hostname be there, and that `any'
be used for a port if they don't care.
Thu May 21 14:13:46 1998 Arnold D. Robbins <arnold@skeeve.com>

just getting old and senile.
Mon May 4 12:42:49 1998 Arnold D. Robbins <arnold@skeeve.com>

builtin variables. Gotta look nice, don't we?
* eval.c (nodetypes): ditto.

overflow the static buffer. This is just a debugging
routine, not worth the hassle of dynamic allocation.

`node->parmlist' in the code.
* awk.y (func_install): rearranged a bit, to build up a list of
the function parameter names and to save it in the `parmlist' field.
* eval.c (push_args): new parameter, `varnames', which is the list
of variable names. Use this to set the vname field of each
parameter's value as it's created. Special case arrays to include
where they came from, mainly for array vs. scalar diagnostics.
(r_tree_eval): don't set the `vname' field for parameters.
(pop_fcall): free the `vname' field if it's an array.
(func_call): pass in the `parmlist' field to call of push_args().
(r_get_lhs): for Node_subscript, change error message to use
the `vname' field.

into moral equivalent of `delete foo'.
* array.c (do_delete_loop): new routine.
* awk.h [NODETYPE]: new Node_K_delete_loop value.
Add declaration of do_delete_loop.
* awk.y [LEX_FOR]: Fix code to recognize special case.
* eval.c (nodetypes): new entry for Node_K_delete_loop.
(interpret): add case for Node_K_delete_loop, add more
diagnostic info in default (cant_happen) case.
Tue Jul 11 22:15:10 2000 Pat Rankin <rankin@eql.caltech.edu>
* awk.y (nextc): Recast unsigned char values back to int to
prevent VAX C from truncating EOF to 255.
Tue Jul 11 14:08:23 2000 Arnold D. Robbins <arnold@skeeve.com>
* array.c (do_delete): switch to string comparison, not
cmp_nodes.
(assoc_find): add call to force_string on subscript.
* eval.c (interpret): Case Node_K_arrayfor: check for
Node_array_ref and fetch original_array. Yowser.
Fri Jun 30 21:57:00 2000 Arnold D. Robbins <arnold@skeeve.com>
* array.c (assoc_lookup): Don't force the subscript
to be a string. Not a good idea after the change
to using dupnode.
Sun Jun 25 15:08:19 2000 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.0.5: Release tar file made.
Wed Jun 14 13:03:45 2000 Arnold D. Robbins <arnold@skeeve.com>
* field.c (set_record): manage a private buffer for $0.
Keeps things safe in case `getline var' rearranges the
IOBUF's contents that $0 is still pointing into.
Tue Jun 13 16:27:55 2000 Paul Eggert <eggert@twinsun.com>
Upgrade to latest and greatest version of largefile code.
* configure.in (AC_CANONICAL_HOST): Remove.
(GAWK_AC_SYS_LARGEFILE): Defer until after AC_MINIX,
to avoid autoconf warnings.
Rewrite largefile configuration so that we don't need to run
getconf and don't need AC_CANONICAL_HOST.
* config.guess, config.sub: Remove these files.
* Makefile.in (MISC): Remove config.guess, config.sub.
* m4/largefile.m4 (GAWK_AC_SYS_LARGEFILE_FLAGS,
GAWK_AC_SYS_LARGEFILE_SPACE_APPEND): Remove.
(GAWK_AC_SYS_LARGEFILE_TEST_INCLUDES): New macro.
(GAWK_AC_SYS_LARGEFILE_MACRO_VALUE): Change arguments from
CODE-TO-SET-DEFAULT to VALUE, INCLUDES, FUNCTION-BODY.
All uses changed.
Instead of inspecting the output of getconf, try to compile the
test program without and with the macro definition.
(GAWK_AC_SYS_LARGEFILE): Do not require AC_CANONICAL_HOST or check
for getconf. Instead, check for the needed flags by compiling
test programs.
(GAWK_AC_SYS_LARGEFILE): Define _XOPEN_SOURCE to be 500 to
work around glibc 2.1.3 bug.
(GAWK_AC_SYS_LARGEFILE_FLAGS): Don't use -n32 on IRIX if the
installer said otherwise.
(GAWK_AC_SYS_LARGEFILE_FLAGS): Work around a bug in the QNX shell,
which doesn't propagate exit status of failed commands inside
shell assignments.
Wed Jun 7 13:23:09 2000 Arnold D. Robbins <arnold@skeeve.com>
* Updated copyright dates in appropriate files.
Mon May 22 17:29:43 2000 Arnold D. Robbins <arnold@skeeve.com>
* Makefile.in (clean): get `*/core' too.
Sun May 7 16:33:05 2000 Arnold D. Robbins <arnold@skeeve.com>
* array.c (concat_exp): Change ref to `lnode->stlen' and
`lnode->stptr' for SUBSEP to use `var_value->...'.
Tue May 2 09:54:29 2000 Arnold D. Robbins <arnold@skeeve.com>
Fix referencing freed memory as shown by test/arynocls.* tests.
* awk.h [Node_array_ref]: new node type.
[orig_array]: new macro element in NODE structure.
* field.c (do_split): handle case for Node_array_ref, fetch
the original array.
* array.c (in_array, do_delete): ditto.
* eval.c (nodetypes[]): add Node_array_ref string.
(r_tree_eval): handle case for Node_array_ref.
(push_args): push arrays as Node_array_ref, and pass them on.
(pop_fcall): don't unref lnode if it's an array when releasing
local arguments. Check for both Node_array and Node_array_ref.
(r_get_lhs): choke on Node_array_ref as for Node_array.
For Node_subscript, handle Node_array_ref.
Tue May 2 09:52:12 2000 Bruno Haible <haible@clisp.cons.org>
* io.c (redirect): After reopening a `struct redirect', move it to
the head of the list.
Sun Apr 2 17:51:40 2000 Arnold D. Robbins <arnold@skeeve.com>
* re.c (re_update): Check if IGNORECASE has changed, and
if so recompute the re. See test/igncdym.awk.
Mon Mar 20 16:18:34 2000 Arnold D. Robbins <arnold@skeeve.com>
* io.c (set_RS): Added a lint warning about multicharacter RS,
per suggestion from Akim DeMaille (akim@epita.fr).
Sun Feb 13 14:40:32 2000 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (push_args): Fix from Nide Naoyuki <nide@ics.nara-wu.ac.jp>,
re-assign `f' in case tree_eval moved fcall_list around.
Sun Feb 6 11:39:33 2000 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (op_assign): Fix it right. For ++ and --, get the lhs
in the operations, do the op, and then return. For += etc,
get the rhs FIRST, since the lhs can move around as a result,
*then* get the lhs and do the operation. See test/opasnidx.awk.
Tue Feb 1 18:41:40 2000 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (op_assign): reget the rval after regetting
the left hand side. See test/opasnslf.awk for why.
Thu Jan 27 18:06:31 2000 Arnold D. Robbins <arnold@skeeve.com>
* awk.y (yylex): Made ']' not one of the characters
that sets `want_assign' to false. `a[i] /= 2' was
broken. Per bug report from Kristofer T. Karas
<ktk@ktk.bidmc.harvard.edu>.
Wed Dec 22 15:06:37 1999 Arnold D. Robbins <arnold@skeeve.com>
* awk.y: Removed declarations of functions before
definition of `tokentab[]'. They're redundant with
what's in awk.h.
Thu Dec 9 17:01:07 1999 Arnold D. Robbins <arnold@skeeve.com>
* node.c (parse_escape): Add lint warning for unrecognized
escape sequences.
Mon Dec 6 15:17:34 1999 Arnold D. Robbins <arnold@skeeve.com>
* main.c (usage): Changed bug reporting email addresses to
be a reference to `Bugs' node in the online and printed
doc, instead.
Thu Dec 2 13:08:18 1999 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (do_compl): test `d' for negative inside the do_lint
test, not uval. Ooops.
Fri Nov 26 10:58:36 1999 Arnold D. Robbins <arnold@skeeve.com>
* array.c (assoc_find): ALWAYS compare indexes as strings,
don't use cmp_nodes in case they are numeric. Oh my.
Talk about a Day 1 bug!
Tue Nov 23 11:58:53 1999 Arnold D. Robbins <arnold@skeeve.com>
* regex.c (SYNTAX): cast argument to `unsigned char' instead of
&-ing with 0xFF. Hopefully somewhat more portable, ala 21 Nov 99
changes to awk.y.
Sun Nov 21 22:25:27 1999 Paul Eggert <eggert@twinsun.com>
* aclocal.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a
problem with the QNX 4.25 shell, which doesn't propagate exit
status of failed commands inside shell assignments.
Sun Nov 21 20:33:35 1999 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (nextc): remove declaration, don't need it here.
awk.y (nextc): Cast values to unsigned char so that latin-1
characters in strings don't turn themselves into EOF.
Most notably y-umlaut, which is decimal 255.
Mon Nov 1 20:00:25 1999 Arnold D. Robbins <arnold@skeeve.com>
* regex.c (init_syntax_once): move below definition of
ISALNUM etc., then use ISALNUM to init the table, so that
the word ops will work if i18n'ed.
(SYNTAX): And subscript with 0xFF for Latin-1 characters.
Mon Oct 25 18:37:13 1999 Arnold D. Robbins <arnold@skeeve.com>
* awk.h, main.c, io.c: undo previous changes (22 Oct 1999).
* main.c (main): move call to `init_fields()' to before
arg parsing. This allows `-v NF=blah' to work ok.
Fri Oct 22 17:43:40 1999 Arnold D. Robbins <arnold@skeeve.com>
* main.c (arg_assign): Add new arg, `initing' for icky special
casing of -v of special variables. Use it to check for NF.
May need to add other cases later.
(pre_assign): change call arg_assign, passing initing=TRUE;
io.c (nextfile): change call arg_assign, passing initing=FALSE;
awk.h: Change prototype for arg_assign.
Tue Oct 19 16:06:48 1999 Paul Eggert <eggert@twinsun.com>
* io.c (close_redir): Don't munge errno between setting it and
using it.
Wed Oct 6 17:47:47 1999 Arnold D. Robbins <arnold@skeeve.com>
* main.c (arg_assign): return NULL on bad variable. Allows
things like `./3x=stuff' to work as a filename.
Thu Sep 23 21:35:46 1999 Paul Eggert <eggert@twinsun.com>
* aclocal.m4 (GAWK_AC_SYS_LARGEFILE_FLAGS): Work around GCC
2.95.1 bug in HP-UX 10.20 or later. (Had to fix the fix. ADR. :-)
Tue Sep 21 13:31:36 1999 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (format_tree): For '0', only set zero_flag if we
haven't seen the field width or precision yet.
Mon Aug 9 13:06:01 1999 Arnold D. Robbins <arnold@skeeve.com>
* array.c (assoc_lookup): Removed code that gave each array
a private copy of each index. Balloons memory usage for
no good reason that I can see. Just use dupnode in all
cases.
* configure.in: check for $srcdir/.developing adds extra
defines for my testing/debugging use. Yes, hack alert.
Sun Aug 1 11:02:02 1999 Arnold D. Robbins <arnold@skeeve.com>
* node.c (dupnode): turn off FIELD when copying nodes.
* array.c (do_adump, assoc_dump): new functions for array debugging.
* awk.y (tokentab): conditionally add "adump" function for debugging.
* awk.h: delcare new functions.
Thu Jul 29 23:26:40 1999 Arnold D. Robbins <arnold@skeeve.com>
From wsanchez@apple.com:

* config.guess, config.sub: Add MacOS X recognition.
Thu Jul 29 19:09:19 1999 Arnold D. Robbins <arnold@skeeve.com>
* awk.y (func_install): make `function foo(foo)' a fatal error.
eval.c (r_tree_eval): diagnose use of a function name as a
variable inside the function.
Sun Jul 4 16:53:14 1999 Arnold D. Robbins <arnold@skeeve.com>
* eval.c (eval_condition): add extra braces to avoid
gcc warning. I'm not going to bother for the library
code like dfa and regex.
Wed Jun 30 16:14:36 1999 Arnold D. Robbins <arnold@gnu.org>
* Release 3.0.4: Release tar file made. This time for sure.
Wed Jun 30 16:10:11 1999 Arnold D. Robbins <arnold@gnu.org>
* awk.h: add include of <assert.h>, and comment about config.h
having to be included before any system headers. Otherwise,
with egcs-2.91.66 and later on Linux systems, and possibly
others, things break badly, due to the LFS macros.
* awk.y, builtin.c, eval.c, field.c, io.c: removed include
of assert.h
Wed Jun 9 11:39:19 1999 Paul Eggert <eggert@twinsun.com>
Port the large-file code to AIX, HP-UX, and IRIX.
Add cross-compilation support for large files.
* config.guess, config.sub: New files.
* configure.in (AC_CANONICAL_HOST):
Add; GAWK_AC_SYS_LARGEFILE needs this.
(GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.
* aclocal.m4 (GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.
Add support for AIX and HP-UX.
(GAWK_AC_SYS_LARGEFILE_FLAGS, GAWK_AC_SYS_LARGEFILE_SPACE_APPEND,
GAWK_AC_SYS_LARGEFILE_MACRO_VALUE): New macros.
* acconfig.h (_FILE_OFFSET_BITS, _LARGEFILE_SOURCE, _LARGE_FILES):
New macros.
* Makefile.in (MISC): add config.guess and config.sub so they get
included in the distribution.
Wed Jun 9 11:29:29 1999 Paul Eggert <eggert@twinsun.com>
* io.c (iop_alloc): Don't mmap files whose sizes don't fit in `int'.
[ This isn't really needed, as HAVE_MMAP is #undef'ed at the top,
but it's there in case people want to take their life in their hands. ]
Sun Jun 6 11:28:07 1999 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.46: Release tar file made.
Wed Jun 2 14:36:24 1999 Arnold D. Robbins <arnold@gnu.org>

that gawk compiles and tests ok on.
Tue Jun 1 14:24:59 1999 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.45: Release tar file made.
Tue May 25 16:32:37 1999 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (format_tree): more smarts for weird cases, such as
zero precisions and zero values used with the `#' flag.
Thanks to Andreas Schwab (schwab@gnu.org) for pointing these out.
Wed May 19 14:02:54 1999 Arnold D. Robbins <arnold@gnu.org>
* io.c (do_close): move test for `close(FILENAME)' to after
loop through all open redirections. Fixes problems in obscure
cases with redirections in END rules.
Sun May 16 14:08:39 1999 Arnold D. Robbins <arnold@gnu.org>
* awk.y (yylex): fix group of characters including ',' to
set want_assign = FALSE. Fixes bizarre parsing problems in
function call lists, for example.
* io.c (get_a_record): repair logic for single-leading-newline
case.
Tue May 11 16:48:11 1999 Arnold D. Robbins <arnold@gnu.org>
* aclocal.m4 (GAWK_AC_AIX_TWEAK): new macro.
* configure.in: call it
* Makefile.in: (awklib/all): pass CFLAGS on to sub-make so
that password programs will get AIX magic defines. Avoids
having to tweak program code for those in doc/gawk.texi.
Mon May 3 16:56:23 1999 Arnold D. Robbins <arnold@gnu.org>
* array.c (do_delete): don't free_temp(subs) until after all
references to it are finished.
Mon May 3 13:41:16 1999 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.44: Release tar file made.
Sun May 2 18:25:43 1999 Arnold D. Robbins <arnold@gnu.org>
* io.c (get_a_record): Do a really good job of stripping newlines
from the front of records when RS = "" and there's only one
newline at the front of the file, which the regex didn't catch.
Wed Apr 28 12:27:49 1999 Arnold D. Robbins <arnold@gnu.org>
* configure.in: more HP stuff: fix the manual alloca code so that
gawk will compile and link on HP systems. See the comments.
Sun Apr 25 13:39:16 1999 Arnold D. Robbins <arnold@gnu.org>
* Makefile.in (gawk): add $(CFLAGS) to linking step.
* configure.in: correctly do AC_FUNC_GETPGRP on HP systems too.
Tue Apr 13 20:21:00 1999 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.43: Release tar file made.
Tue Apr 13 19:02:20 1999 Arnold D. Robbins <arnold@gnu.org>
* io.c (useropen, pidopen): add casts to int on arguments to
silence gcc warnings.
* regex.c (regcomp,regexec,regfree): add ifdef for APPLE.
Thu Feb 4 10:38:02 1999 Arnold D. Robbins <arnold@gnu.org>
* custom.h: hacks for BeOS. Not documented in the manual right now.
* configure.in: hacks for BeOS. Check for HP-UX and define C_ALLOCA
if not using gcc. I wish they'd just fix bison already.
Sun Dec 20 16:57:38 1998 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.42: Release tar file made.
Sun Nov 15 21:05:39 1998 Arnold D. Robbins <arnold@gnu.org>
* io.c (gawk_popen): Add WIN32 to list of systems that use
the non-real-pipe version. From the PC gawk guys.

* BETA Release 3.0.41: Release tar file made.
Tue Nov 3 16:24:35 1998 Arnold D. Robbins <arnold@gnu.org>
* eval.c (r_get_lhs): Fix the cases for the special variables,
don't unref their current value if it's the same as the internal
copy; perhaps the current one is used in a concatenation or some
other expression somewhere higher up in the call chain. Ouch.
See test/getnr2tm.awk.
Sun Nov 1 15:24:52 1998 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (format_tree): improve handling of zero-fill
when a precision is present. See test/zeroflag.awk.
Wed Oct 28 20:40:17 1998 Arnold D. Robbins <arnold@gnu.org>
* eval.c (r_tree_eval): Case for Node_concat. Get lengths
separately, in case one expression has a side effect that
that changes another. Ugly, but it keeps gawk from core
dumping. See test/nasty.awk.
Sun Oct 18 21:27:24 1998 Arnold D. Robbins <arnold@gnu.org>
* awk.y (append_right): bug fix, if `list' or `new' are NULL,
return `list', so that things don't break too badly.
* regex.c (re_compile_fastmap): remove unused variable `num_regs'.
Thu Oct 8 19:36:57 1998 Arnold D. Robbins <arnold@gnu.org>
* BETA Release 3.0.40: Release tar file made.
Mon Jul 27 10:14:33 1998 Arnold D. Robbins <arnold@gnu.org>
* node.c (parse_escape): Remove assignment with side effects
from ISXDIGIT test. Thanks to "Mihai T. LAZARESCU"
<mihai@ccmserv.polito.it> for pointing this out.
Mon Apr 27 11:31:32 1998 Arnold D. Robbins <arnold@gnu.org>
* main.c (usage): fix the email address for the bug list.
(copyleft): update the copyright year.
Mon Mar 23 21:22:32 1998 Arnold D. Robbins <arnold@gnu.org>
* eval.c (r_get_lhs): make sure that values of type
Node_param_list don't have the FUNC flag set. This means
we don't allow the use of a function name as a variable or
array from within the function.
Sun Mar 22 19:12:32 1998 Paul Eggert <eggert@twinsun.com>
* aclocal.m4 (GAWK_AC_LARGE_FILES): new macro that checks for
large file support, and updates CPPFLAGS, LDFLAGS, LIBS as
needed.
* configure.in: call GAWK_AC_LARGE_FILES.
* Makefile.in (CPPFLAGS, LDFLAGS): Let autoconf configure.
(COMPFLAGS): Add $(CPPFLAGS).
Mon Mar 16 14:06:41 1998 Arnold D. Robbins <arnold@gnu.org>
* field.c (using_FIELDWIDTHS): new macro.
(using_fieldwidths): use new macro.
(do_split): in case for FS_DFLT, also check that
we're not using FIELDWIDTHS. Otherwise, split() would use
FIELDWIDTHS, not current value of FS. Oops.
Sun Nov 16 20:08:59 1997 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (sub_common): fix for count of matches in gsub
from Geert.Debyser@esat.kuleuven.ac.be.
Wed Oct 15 03:38:12 1997 Arnold D. Robbins <arnold@gnu.org>
* field.c (set_FS): Use `sc_parsefield' if the value of FS is not
alphabetic OR if not ignoring case. Bug fix if IGNORECASE
is true and FS happens to be '^'. Sheesh, talk about obscure.
(rebuild_record): Add more smarts to the code that sets up the
fields. Thanks to Alan J. Broder (ajb@dtmr.com).
Sun Oct 5 11:56:52 1997 Arnold D. Robbins <arnold@gnu.org>
* configure.in: if ISC add -D_SYSV3 to CFLAGS, per email from
Mario Vanoni (vanonim@dial.eunet.ch).
Fri Sep 26 00:57:49 1997 Arnold D. Robbins <arnold@gnu.org>
* awk.y (append_right): return if either list is NULL. Prevents
syntax errors from causing core dumps.
Wed Sep 17 15:34:15 1997 Arnold D. Robbins <arnold@gnu.org>
* field.c (rebuild_record): set things up so that all fields point
into the new record and release any changed fields without
causing memory leaks. Avoids problems when fields are extended
with the value of $0 or other fields and then $0 is assigned to.
Mon Sep 15 16:12:55 1997 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (do_print): when testing for NUMBER, make sure
it's not a string too. Thanks to Michael Brennan for
clarifying the semantics.
Sun Sep 14 19:55:12 1997 Arnold D. Robbins <arnold@gnu.org>
* node.c (format_val): always format values ourselves: avoids
problems if OFMT is bizarre, like %s.
Sun Sep 14 00:08:53 1997 Arnold D. Robbins <arnold@gnu.org>
* io.c (get_a_record): replace all occurrences of the test
`grRS == FALSE' with `RS_is_null' which makes ` RS = "\0" '
actually work, is clearer code, and actually makes use of
the `RS_is_null' variable!
Sun Aug 17 07:15:12 1997 Arnold D. Robbins <arnold@gnu.org>
* field.c (set_FS): Change logic to always set parse_field, even
if FS hasn't changed. Thanks to Igor Sheyn for catching this.
Wed Aug 6 21:04:37 1997 Arnold D. Robbins <arnold@gnu.org>
* io.c (VMS et al gawk_popen): use pclose, not fclose, if
iop_alloc fails.
Wed Jul 30 19:53:52 1997 Arnold D. Robbins <arnold@gnu.org>
* awk.y [variable]: fix case for subscript if $3 == NULL.
Sun Jul 27 22:47:30 1997 Arnold D. Robbins <arnold@gnu.org>
* awk.y (get_src_buf): don't close file if it's stdin.
Sun Jul 27 22:47:15 1997 Pat Rankin <rankin@eql.caltech.edu>
* io.c (#if VMS: vmsrtl_fileno): new routine.
(#if VMS: fileno): new macro substituted for stdio one.
Thu Jul 17 20:05:59 1997 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (do_print): When OFMT != CONVFMT, create a new
temporary node with just the numeric value valid and format it,
and use that for printing. Avoids memory corruption.
Wed Jul 16 10:01:16 1997 Arnold D. Robbins <arnold@gnu.org>
* regex.c: When SYNTAX_TABLE is defined, but not emacs, then
CHAR_SET_SIZE is not defined, though used in regcomp. It should
be taken out of #ifdef SYNTAX_TABLE. Fix from bug group, from
Akim Demaille, demaille@inf.enst.fr.
* awk.h (isnondecimal): make test a little smarter.
builtin.c (nondec2awknum): add bailout for decimal numbers, e.g.
`00.1'. Fix from Larry Schwimmer <rosebud@cyclone.Stanford.EDU>.
Thu Jun 19 19:00:40 1997 Arnold D. Robbins <arnold@gnu.org>
* eval.c (interpret): case Node_K_next, Node_K_nextfile: fatal
error if called from BEGIN or END.
(Fixed completely Mon May 3 13:31:42 1999.)
Mon Jun 9 22:40:04 1997 Arnold D. Robbins <arnold@gnu.org>
* builtin.c (nondec2awknum): Allow `f' and `F' in hexadecimal numbers.
Gotta get more sleep...
* array.c (assoc_lookup): Fix from Tom Karzes (karzes@equator.com)
for memory leak when forcing type to Node_var_array.
Thu May 15 12:49:08 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Release 3.0.3: Release tar file made.
Wed May 14 08:06:08 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (do_close): add lint warning if closing something that
isn't open.
Tue May 13 12:14:12 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* random.c, builtin.c: remove __GLIBC__ tests, since it breaks
`make test'. I prefer consistency across platforms.

Mon May 5 21:17:37 1997 Pat Rankin <rankin@eql.caltech.edu>
* missing/strftime.c [case 'v', VMS_EXT]: for VMS date format, two
digit day of month should not be zero padded on the 1st through
the 9th.

Fri Apr 25 16:52:33 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* array.c (grow_table): add a bunch more large primes so arrays
can get really big. Thanks to christos@deshaw.com.
* all files: remove ifdef'ed out code and update copyrights.
* Makefile.in (gawk): add $(COMPFLAGS) to command line.
* eval.c (flags2str): added case for FIELD.
Thu Apr 24 22:39:23 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* COPYING: changed to current official version from FSF.
* regex.c: merge with GLIBC version.
* awk.h [_GNU_SOURCE]: bracket definition inside ifdef.
(NODE.source_line): move name member out of `x' union and
into `nodep'; avoids problems doing diagnostics.
(nondec2num): put decl into #if BITOPS || NONDECDATA
* posix/gawkmisc.c, missing/system.c, missing/strtod.c,
missing/strerror.c: move to generic GPL statement at top.
* builtin.c (nondec2num): put into #if BITOPS || NONDECDATA
Wed Apr 23 22:14:14 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* dfa.c: misc changes for really pedantic SGI compilers.

ifdef NONDECDATA.
Tue Apr 15 06:32:50 1997 Pat Rankin <rankin@eql.caltech.edu>
* missing/strftime.c (malloc, realloc, getenv, strchr): only
declare these when STDC_HEADERS is not defined.
<stdlib.h, string.h>: include these when STDC_HEADERS is defined.
* awk.h (freenode, tree_eval, m_tree_eval): reorganize definitions.
* alloca.c (malloc): if malloc is already defined as a macro,
presumeably by config.h, don't define or declare it.
Wed Apr 9 22:45:27 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Makefile.in [COMPFLAGS]: per suggestion from Karl Berry, put
$(CFLAGS) last.
Tue Apr 8 23:54:46 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (interpret): For Node_K_break and Node_K_continue, if
treating them like `next', also check the function call stack
and pop it if necessary.
Mon Apr 7 18:22:37 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.h: Add decls of new routines do_compl() and set_loc().

(do_substr): rationalized yet again, now notices negative start
and length parameters.
* eval.c (push_args): fix if call_list gets realloc'ed in the
middle of things. Avoids crash for deeply nested function calls.
* main.c (catch_sig): add call to set_loc().

variables to help out in tracing down source of error messages.
Fri Mar 28 08:42:27 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (iop_alloc, iop_close): Undo changes of Feb 11, apparently
other cleanups in io.c made mmap stuff start working again.
BAH! It's a mess, the test suite still fails. I'm leaving the
mmap stuff undefined for now. It'll probably get ripped out in 3.1.
Thu Mar 27 08:48:57 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* custom.h [_SEQUENT_]: undef HAVE_MMAP.
Wed Mar 26 09:08:16 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (iop_alloc): fix definition to make it static.
Mon Mar 24 23:09:07 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* field.c (init_fields, etc..): more clean up use of Null_field
and the various flags.
* node.c (unref): if a field, free the node itself. Fixes
memory leak problems.
Sun Mar 23 22:51:09 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.h [FIELD]: new flag for node->flags field.
* builtin.c (sub_common): if FIELD is set, dup the string.
* field.c (init_fields): set up a new Null_field global var.
(init_fields, set_field, set_record) use the FIELD flag.
(getfield): use Null_field instead of private variable.
* io.c (wait_any): comment out calls to pclose and iop_close,
caused weird race conditions. See test/pipeio1.awk. Thanks
to Darrell Hankerson for tracing this one down.
Tue Mar 18 20:57:18 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* dfa.c (inboth): free templist; plugs memory leak.
* field.c (init_fields, grow_fields_arr, set_field, rebuild_record,
set_record): remove PERM flag from entries in fields_arr[]. Fixes
nasty memory leak.
Tue Mar 18 06:33:00 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.y (dup_parms): robustified against parameter errors.
Sun Mar 16 21:31:40 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
* acconfig.h [BITOPS]: new macro. If set, do octal & hex and bit ops.
* awk.h [isnondecimal]: new macro, and decl of new functions.
* awk.y (yylex): add recognition of octal and hex constants.
* builtin.c (do_and, do_or, do_xor, do_lshift, do_rshift): new
functions that do bit operations.
(nondec2awknum): new function to convert octal or hex to double.
* configure.in: Add AC_ARG_ENABLE for bit operations.
* node.c (r_force_number): add octal and hex conversion.
Sun Mar 16 21:28:56 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.h [IOP_NOFREE_OBJ]: new macro.
* io.c (iop_open, iop_alloc): add new third parameter, which is
either NULL, meaning allocate a new IOP, or the address of one
already allocated. Have a static one in the `nextfile'
routine, and use the IOP_NOFREE_OBJ flag for it. All of this
keeps us from reading freed memory. The `swaplns' test fails
otherwise.
(iop_close): if IOP_NOFREE_OBJ is set, don't free the IOBUF.
Wed Feb 26 06:21:02 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (in_function, pop_fcall_stack, pop_fcall, push_args):
new functions. These manage "frames" of awk function call arguments.
The problem is that a `next' or a `nextfile' from a function
leaks memory. These changes allow us to free up that memory.
(interpret): for Node_K_next and Node_K_nextfile, check if in
a function call and free all function call frames.
Fri Feb 21 06:23:19 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Misc changes from Katsuyuki Okabe <HGC02147@niftyserve.or.jp>:
* builtin.c (do_substr): change a %d to %ld in warning message.
* eval.c (op_assign): fix format string for warning about %=.
Wed Feb 19 23:29:02 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* main.c (main): add do_intervals to condition that causes
resetup() to be called again. Makes the --re-interval option
actually work. What a concept.
Fri Feb 14 09:47:31 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c [#include "awk.h"]: undef HAVE_MMAP to just use the old code.
Something is causing a file descriptor leak, and this is getting to
be just too much hair. I reserve the right to rip out the mmap
code entirely at a future date.
Tue Feb 11 06:28:29 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (iop_alloc): for an mmap'ed file, close the file descriptor,
and then touch each page to get a private copy. Fixes nasty case
of truncating our input file.
(iop_close): don't call close on mmap'ed file.
Wed Feb 5 17:59:04 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (interpret): For Node_K_delete, just call do_delete; let
it handle the case of `delete array'.
* array.c (do_delete): Changed to handle case of `delete array',
and made smarter if the array is actually an uninitialized
parameter.
Sun Jan 26 22:58:29 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* getopt.h, getopt.c, getopt1.c: replaced with new versions from
GLIBC 2.
Sun Jan 19 23:37:03 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (nodetype2str): not static, for debugging.
(flags2str) new function: for debugging.
* field.c (get_field): add new var that is like Nnull_string but
does not have numeric attributes, so that new fields are strings.
(set_record): turn off PERM flag before unrefing fields and field 0.
* array.c (in_array): always evaluate subscript, could have
side effects.
* builtin.c (do_strftime): way increase size of buffer to make sure
we don't have overflow problem. Keeps Paul Eggert happy.
* custom.h [__amigaos__]: define fork to vfork. From Fred Fish.
* dfa.c: move include of config.h to top, for RSXNT. From Kai
Uwe Rommel.
(ISALPHA, etc): change from Jacob Engelbrecht (jaen@novo.dk)
to better handle non-ascii environments.
* gawkmisc.c: remove amigados case, posix should now work fine.
* amiga/*: nuked per previous entry.
* Makefile.in: removed all references to amiga
* io.c [HAVE_SYS_PARAM_H]: Add #undef RE_DUP_MAX to avoid
spurious conflict with regex.h.
(flush_io): remove amiga ifdefs, not needed anymore.
(spec_setup): set getrec field for special files. Fix from
Mark Gray (markgray@pdt.net).
* node.c (more_nodes): fix to get the last entry in the array.
Wed Jan 8 17:42:37 1997 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* io.c (mmap_get_record): Fix return value if file ends without
record separator.
Fri Jan 3 19:57:16 1997 Pat Rankin <rankin@eql.caltech.edu>
* awk.y (get_src_buf): Test for an empty source file by detecting
an initial read of 0 bytes rather than by relying on info from
stat().
Wed Dec 25 11:25:22 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Release 3.0.2: Release tar file made.
Wed Dec 25 11:17:32 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Makefile.in (install, uninstall): use $(srcdir)/patchlevel.h.
Thanks to Richard Levitte, LeViMS@stacken.kth.se.
(install): remove chmod command; let $(INSTALL_PROGRAM) use -m.
Mon Dec 23 20:36:59 1996 Pat Rankin <rankin@eql.caltech.edu>
* custom.h (#if VMS_POSIX): Define GETPGRP_VOID.
Fri Dec 20 08:59:55 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* getopt.c, getopt1.c: comment out the `#if defined (_LIBC) ||
!defined (__GNU_LIBRARY__)' and `#endif' to force use of this
getopt, even on systems like linux. This will be handled
better in 3.1 / glibc 2.
Thu Dec 19 22:52:39 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.y (yylex): In several places, after yyerror(), add call to
exit(). Otherwise, infinite messages. This should probably
be handled better.
Wed Dec 18 22:42:10 1996 Darrel Hankerson <hankedr@mail.auburn.edu>
* getopt.c (_getopt_internal): if 'W' and ';', if optind == argc,
return c, don't fall through.
Wed Dec 18 10:09:44 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* configure.in [AC_PREREQ]: Update to 2.12 in order to switch to
autoconf 2.12. Lots of other files will be rebuilt automatically.
[AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
* aclocal.m4 [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
Tue Dec 17 22:23:16 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (do_strftime): fix case if format string is "".
Also fix it if format is not "" but result of strftime is "".
See comments in code.
Tue Dec 10 23:09:26 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Release 3.0.1: Release tar file made.
Tue Dec 10 22:39:41 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>

Sun Dec 8 07:53:44 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Makefile.in (gawk): took COMPFLAGS out of link line for help
on VMS posix. Shouldn't (I hope) affect anything else.

if --traditional.
Thu Nov 7 20:54:43 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (inrec): make sure EOF hasn't already happened before
trying to read; prevents accessing freed buffer. Thanks to
Michal Jaegermann.
* Makefile.in [AWKSRC]: add random.h.
random.h: new file, redefines names of the `random' functions.
random.c, builtin.c: add include of random.h.
Thu Nov 7 09:06:21 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.y (snode): undo 4 Oct change, put do_split code back.
field.c (do_split): restore old code; add test for CONST, so
that re_parse_field is used if third arg to split is a regexp
constant.
Mon Nov 4 12:57:11 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* main.c (main): Research -m[fr] options don't need literal '='
characters. Brian's documentation was confusing. Fixed, not
that anyone actually uses these options with gawk.
Sun Nov 3 11:23:21 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* field.c (def_parse_field): add \n to list of acceptable white space.
(posix_def_parse_field): new routine, just like def_parse_field(),
but only allows space and tab as separators.
(do_split, set_FS): make appropriate choice between the two
*def_parse_field() routines.
Fri Oct 25 10:13:06 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>

Wed Oct 23 19:46:01 1996 Pat Rankin <rankin@eql.caltech.edu>
* builtin.c (do_tolower, do_toupper): Add `unsigned char *' casts.
Tue Oct 22 21:27:52 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c [GAWK_RANDOM_MAX]: Try to make definition a bit
smarter; don't use RAND_MAX if it's equal to SHRT_MAX, blows
things up.
Tue Oct 22 08:49:20 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* main.c (copyleft): update copyright date to 1996.

of a regexp.
Fri Oct 4 10:26:16 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.y (snode): remove case for do_split; always making the
third arg a Node_regex is wrong.
field.c (do_split): rationalized to distinguish `/ /' from `" "'.
Generally fixed up.
* node.c (parse_escape): Allow single digit \x escapes.
1996-10-02 Paul Eggert <eggert@twinsun.com>
* builtin.c (format_tree):
Fix bug in %d and %i format: NaNs, and values
in the range LONG_MAX+1 .. ULONG_MAX, were mishandled.
Don't assume that double values <= -1 are converted to unsigned
long in the expected way; the C Standard doesn't guarantee this.
1996-10-02 Paul Eggert <eggert@twinsun.com>
* awk.h (INT_MAX): Remove unused symbol.
Mon Sep 30 22:19:11 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* getopt.c (_getopt_internal): If 'W' is in the optstring followed
by a ';' then search through the long opts table. This makes
`-W foo=bar' same as `--foo=bar'.
* main.c (main): 'W' now prints an error message.
(gawk_option): deleted the routine.
Sun Sep 29 23:04:54 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (sub_common): fix several bugs with gsub when
matching null strings. See test/gsubtest.awk.
Fri Sep 20 17:35:54 1996 Pat Rankin <rankin@eql.caltech.edu>

Fri Sep 20 11:54:31 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (do_print): evaluate all the expressions first and
then print them. Avoids surprising behavior. See test/prtoeval.awk
for an example.
Tue Sep 10 06:21:40 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.h [FUNC]: new flag, marks a Node_parameter_list as really
being the function name; allows more checking in awk.y.
* awk.y (isassignable): now takes a NODE * instead of a type, to
check if a function parameter is marked FUNC, then it's the function
name, which is not assignable. Fix call from snode().
(function_prologue): mark function name as FUNC.
(yyerror): don't call exit() anymore; gawk will now report
all syntax errors.
Sun Sep 1 19:36:30 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* field.c (rebuild_record): after building new field 0, go through
all old fields, and if they used to point into the old one,
have them point into the new one. Then turn off PERM flag before
unref-ing field 0.
Wed Aug 28 19:13:34 1996 Arnold D. Robbins <arnold@math.utah.edu>
* eval.c (set_IGNORECASE): Correctly parenthesize bit operations

Thu Aug 8 23:29:43 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* parse.y (isassignable): new function, checks in type can
be assigned to.
(snode): changed checking for 3rd arg of gsub to be more
general, supersedes earlier change.
Thu Aug 8 13:58:26 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* parse.y (snode): If third arg to sub or gsub is builtin
function, complain, since can't substitute into result.
* eval.c (r_get_lhs): diagnose Node_builtin as an error, instead
of falling through into default case and using cant_happen().
Thu Aug 1 07:13:14 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* regex.h [RE_DEBUG]: new macro.
[RE_SYNTAX_GNU_AWK]: add RE_DEBUG.
[RE_SYNTAX_POSIX_AWK]: add RE_INTERVALS.
* regex.c (re_set_syntax): add #ifdef DEBUG code to turn on `debug'
flag if RE_DEBUG set, and turn off debug if not set and debug
was on.
* main.c (main): remove `do_intervals = TRUE' from `if (do_posix)',
it's now handled in the definition of RE_SYNTAX_POSIX_AWK.
Mon Jul 29 17:49:07 1996 Pat Rankin <rankin@eql.caltech.edu>
* io.c (O_ACCMODE): define it if <fcntl.h> doesn't.
Mon Jul 29 12:02:48 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (set_IGNORECASE): made somewhat smarter. gawk -v IGNORECASE=0
was acting the same as -v IGNORECASE=1. Thanks to Darrell Hankerson
for the bug report.
Fri Jul 26 12:04:43 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* awk.h (format_val): add declaration of new routine.
* node.c (format_val): new routine, abstracts old guts of
r_forcestring; accepts format string and index as additional params.
(r_force_string): changed to call format_val.
* builtin.c (do_print): don't tree_eval the tree twice in case
OFMTidx != CONVFMTidx; doing so could cause side effects
(from bug report by Tobias Rettstadt, xassp@ipds.uni-kiel.de).
Instead, call format_val.
Mon Jul 22 21:59:15 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (iop_close): change check for "is $0 in the input buffer"
to use `< (iop->buf + iop->secsiz + iop->size)' instead of
`< iop->end'. The latter is bogus if EOF has been hit on the
file. Fix from Darrel Hankerson based on bug report by
Charles Howes (howes@grid.direct.ca). See test/eofsplit.awk.
Thu Jul 18 19:43:20 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (sub_common): backed out change of Feb 14 in favor of:
(do_gensub): Changed to use make_string and then to |= TEMP
flag, based on bug report and patch from Katsuyuki Okabe,
hgc02147@niftyserve.or.jp.
Thu Jul 18 19:23:53 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* custom.h: added ifdef for QNX, based on bug report from
Michael Hunter, mphunter@qnx.com.
Mon Jul 15 09:31:01 1996 Arnold D. 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.
eval.c (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.
