Raw Blame History

Mon Aug 7 15:23:00 2000 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.0.6: Release tar file made.
Thu Aug 3 17:47:53 2000 Greg McGary <greg@mcgary.org>
* regex.c: patches for gcc bounded pointer handling.
Thu Aug 3 13:09:09 2000 Arnold D. Robbins <arnold@skeeve.com>
* array.c (in_array, do_delete): fix tests for index equality
when searching through the array to work correctly when
index is "".
Fri Jul 14 21:40:17 2000 Pat Rankin <rankin@eql.caltech.edu>
* builtin.c (format_tree): Workaround a DEC C V5.7 bug by
splitting `strcpy() + 3' into two expressions (the builtin
inline strcpy evidently has erroneous return type of void *
instead of char *; reputedly fixed in V6.1).
* eval.c (C): New macro.
[casetable]: Use it to add explicit casts for the character
values outside the range of 0 to 127.
* missing/strncasecmp.c [C, charmap]: Likewise.
* io.c (redirect): Add EIO check on failed open for VMS.
Fri Jul 14 11:57:23 2000 Arnold D. Robbins <arnold@skeeve.com>
Efficiency hack: turn `for (iggy in foo) delete foo[iggy]'
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:
* Makefile.in (install-strip): new target, coding stds. compatibility.
* 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>
* PORTS: Updated with a more recent list of systems
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.
Wed Nov 4 11:32:24 1998 Arnold D. Robbins <arnold@gnu.org>
* 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>

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.
* Makefile.in (gawk): undid April 25 changes and added comment.
Putting COMPLAGS in breaks with -g on VMS POSIX.
Sun May 11 14:48:04 1997 Darrell Hankerson <hankedr@mail.auburn.edu>

Sun May 11 07:04:01 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (do_print): in the loop that evaluates each expression
to be printed, do a dupnode to avoid bizarre output. Thanks to
Michal for finding this problem.
* awk.y (yylex): fix scanning of hexadecimal constants.
Wed May 7 15:09:25 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* io.c (get_a_record): fix casetable indexing with cast to int.

Tue May 6 16:40:19 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* eval.c (func_call): removed unneeded variables.
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.
Mon May 5 06:33:47 1997 Arnold D. Robbins <arnold@skeeve.atl.ga.us>

Mon May 5 06:33:47 1997 Pat Rankin <rankin@eql.caltech.edu>
* io.c (nextfile): move the check for null return from iop_open
in the normal case and add one for the "no args" case.
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().

* builtin.c (do_compl): new function to do ones complement.
(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>

does makeinfo.
(install): use $(LN) not $(LN_S) to link gawk gawk-version.
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.

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>

* 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.

main.c (main): call setlocale().
builtin.c (do_tolower, do_toupper): use unsigned char pointers,
to get other charsets right in different locales.
Wed Oct 16 21:32:53 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us>
* builtin.c (format_tree): Change initial buffer size to 512

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 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
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 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.
