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

	  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,

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().
	* awk.y (tokentab): add entry for "compl" function.

	  (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().
	* msg.c (set_loc, srcfile, srcline): new function and private
	  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.

	  for Ultrix.

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

	* builtin.c (do_printf): if no args, fatal error. Return silently
	  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.

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.

	* builtin.c (format_tree): Change initial buffer size to 512
	  and use a constant. Allows large values of %f per bug report
	  from sheyn@cs.bu.edu.

	  (local-distclean): added TAGS and tags
	  (maintainer-clean): removed TAGS and tags

Wed Oct 16 12:28:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (version): Add call to copyleft(), per new standards.
	  version.c: Fix text of version string to match new standards.

Sun Oct  6 22:19:45 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.c: updated to Emacs 19.34b base.

Sun Oct  6 21:57:34 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* re.c (make_regexp): fixed to handle \8 and \9 in the middle
	  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.
