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,

Tue Apr 15 21:35:45 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
* acconfig.h [NONDECDATA]: new macro.
* awk.h: add decl of do_strtonum.

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.

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 thoe 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.
* alocal.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>
* Makefile.in (dist): add dependency on `info'. Remove line that
does makeinfo.

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.
Thu Nov 28 11:52:24 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh.

for Ultrix.
Sun Nov 24 22:16:26 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>

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

* 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.

* configure.in: use it.
Thu Oct 17 21:43:25 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>

awk.h: include locale.h and define out setlocale() if not available.
main.c (main): call setlocale().
builtin.c (do_tolower, do_toupper): use unsigned char pointers,

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>
* alloca.c (NULL): don't define if <config.h> has already done so.
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 suprising 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
in test and fix logic for string value.
Wed Aug 28 22:06:33 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* main.c (usage): add email addresses for bug reporting, per
change in GNU Coding Standards from RMS.
Sun Aug 11 23:13:22 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* Makefile.in (install): correct use of $(INSTALL_PROGRAM).
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 parrallel 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 diganostics.
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 accompagnying 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.
