Sun Jun 3 13:04:44 2001 Arnold D. Robbins * Release 3.1.0: Release tar file made. And there was rejoicing. Wed Apr 25 11:44:07 2001 Arnold Robbins * Makefile.am (AM_MAKEFLAGS): Add definition per advice from Nelson Beebe. Tue Apr 24 14:28:00 2001 Arnold Robbins * io.c (devopen): Patch from Jeurgen to robustify pulling out hostname, port numbers, etc, to avoid any buffer overrun problems. Mon Apr 23 10:26:38 2001 Arnold Robbins * awkgram.y: Fix grammar so that `print ... |& ".." |& getline' dies with a parse-time error message. Sun Apr 22 16:46:48 2001 Arnold Robbins * io.c (socketopen): Fix from Juergen in recursive call. Thu Apr 19 18:39:20 2001 Pat Rankin * awk.h: Really fix logic around include of . * awk.h (callresult): New name for `result' macro. * eval.c (r_get_lhs, case Node_builtin): Use it. Thu Apr 19 16:31:09 2001 Pat Rankin * io.c: Move code around to allow compilation with DEC C. Thu Apr 19 16:21:56 2001 Arnold D. Robbins * random.h: Move decl of random() here. * random.c: Remove decl of random(). Mon Apr 9 11:41:58 2001 Arnold D. Robbins * dfa.c (dfainit): Initialize more members in the structure, based on bug report in bug.gnu.utils by aaronl@vitelus.com (Aaron Lehmann). * awk.h: Fix logic around include of . Thu Apr 5 20:12:05 2001 Pat Rankin * dfa.c: for VMS, #include instead of . * missing_d/mktime.c: likewise. * random.c: reorder include directives to get gawk config info from random.h sooner. [fcntl.h]: guard #include with HAVE_FCNTL_H test. [unistd.h]: guard #include with HAVE_UNISTD_H test. * random.c (srandomdev): skip /dev/urandom usage if O_RDONLY is not defined. Tue Mar 20 11:07:11 2001 Arnold D. Robbins * awkgram.y (function_body): Add opt_nls to end of production. Tue Mar 20 09:30:32 2001 Pat Rankin * awk.h (BROKEN_STRNCASECMP): Add decl of strcasecmp. * io.c (two_way_open): Add `return FALSE;' for fussy compilers. Sun Mar 18 15:10:56 2001 Arnold D. Robbins * io.c (gawk_pclose): Set the exit value for close correctly if the pipe died with a signal. Wed Mar 7 11:28:52 2001 Arnold D. Robbins * io.c (get_a_record): Correctly handle the case of a leading single newline at the front of the file when RS = "". 2001-02-26 Paul Eggert * COPYING: Incorporate latest version from FSF, which fixes a Y2k bug. * builtin.c (do_mktime): Allow the user to specify the tm_isdst member as an optional trailing integer, and to specify "out-of-range" members. Check for overflow when subtracting 1 from month or 1900 from year. Allow years just past INT_MAX, as they work on some hosts when INT_MAX - 1900 is representable as an int. * doc/gawk.1, doc/gawk.texi: Document the above changes. Also, document that the origin-zero Gregorian calendar is used. Fix confusing wording about "midnight" by replacing it with 00:00 ("midnight" is also 24:00, the end of the day). Mention the typical range for time stamps. Do not assume that years are nonnegative and are less than 10,000. Suggest TZ=UTC0 instead of TZ=GMT0, as that's how recent versions of GNU date behave. GMT is not always the time of day in Greenwich these days. Fix typos: "Emporer/Era", "1980's", "1970's". * m4/largefile.m4: Synchronized with latest version. Tue Feb 27 12:10:11 2001 Arnold D.

Tue Feb 6 18:17:13 2001 Michal Jaegermann * regex.c (re_match_2_internal): Case maybe_pop_jump, for charset and not_charset: change cast from (unsigned char) to (unsigned). Catches last 8 chars with high bit set if backtracking. See test/rebt8b1.awk, test/rebt8b2.awk. Tue Feb 6 11:20:21 2001 Arnold D. Robbins Have `for (iggy in foo)' save the elements and loop over them. Make sorted for loops a dynamic test instead of a compile time test. Still requires being Strong In The Ways Of The Source. * awk.h: (struct search): removed. (assoc_scan, assoc_next): removed declarations. * array.c (assoc_scan, assoc_next): removed functions. * eval.c (interpret): remove Node_K_array_sorted_for. Change code at Node_K_arrayfor.

Robbins * eval.c (interpret): use tree->rnode->exec_count to hold count of times if was true. profile.c (interpret): ditto. * main.c (pre_assign): gross hack. malloc fresh copy of assign so can clear the '=', otherwise screws up profiling print out. Sun Jan 28 16:16:02 2001 Arnold D. Robbins Per request from Nelson Beebe, SIGHUP to pgawk dumps profile and function call stack and exits, SIGUSR1 dumps and continues running. * eval.c (dump_fcall_stack): New function, dumps awk function call stack. * awk.h (dump_fcall_stack): Add declaration.

(close_redir): Switch mode of stdin back to binary if BINMODE is in effect, after the child returns. * builtin.c (do_system): Restore the mode of stdin before running the child process and switch it back if BINMODE is in effect after the child returns. * awk.h (os_restore_mode): Add prototype. Thu Jan 18 14:03:06 2001 Arnold D. Robbins * custom.h, README_d/README.ultrix: Fixes for Ultrix from Juergen Kahrs. Wed Jan 17 11:03:40 2001 Eli Zaretskii * io.c (redirect) [F_GETFL && O_APPEND]: Use binmode in the call to fdopen. Mon Jan 15 16:29:52 2001 Arnold D. Robbins * profile.c (prec_level): Made Node_K_getline higher than < but lower than others. Allows use of getline with redirection inside an if. Wed Jan 10 15:35:06 2001 Arnold D. Robbins * eval.c (set_BINMODE): Rationalized string assignment. Sun Jan 7 15:26:16 2001 Arnold D.

Robbins Fixed minor memory leaks. * re.c (re_update): When IGNORECASE changed, unref(t->re_text). * eval.c (pop_fcall): Fix the logic to correctly free the vname when copying array args back to their underlying source. Fixed massive memory leaks. * node.c (dupnode): If PERM is set, do nothing. (unref): Fix logic. Always turn off TEMP.

Add a minor memory cleanup facility (undocumented): * awk.h (do_tidy_mem, release_all_vars): Add declarations. * main.c (do_tidy_mem): Add declaration. (main): if $TIDYMEM exists, do_tidy_mem is true, and call mtrace(). * awkgram.y (release_all_vars): New function. Sun Dec 31 10:47:37 2000 Arnold D. Robbins * awkgram.y (in_end_rule): Renamed `parsing_end_rule' to avoid conflict with global var of same name. Sun Dec 24 10:36:54 2000 Eli Zaretskii * awkgram.y (snode): Reword the error message about the number of arguments for a builtin, so as not to use the English `s' as a plural suffix. Tue Dec 12 08:38:03 2000 Arnold D. Robbins * ext.c (do_ext): ifdef out use of `dummy'. Duh. * regex.c (re_error_msgid): Revert to array of `char *' so that can compile on K&R compilers.

Robbins * ext.c (dummy): Make gcc specific via ifdef. * builtin.c (do_dcgettext): make conditional compilation smarter. * msg.c (warning, error, r_fatal): Finish switching back to multi-version function header. Wed Dec 6 13:28:58 2000 Arnold D. Robbins * random.h: include to get ssize_t definition. * awkgram.y (yyerror): Restore multi-version function header, it seems that what ansi2knr produces doesn't quite do the job on old compilers. msg.c (msg): Ditto.

Sun Nov 12 17:45:44 2000 Arnold D. Robbins * builtin.c (parse_next_arg): Fix call to >= num_args so running out of args check is correct, instead of core dumping. (format_tree): Save and restore `the_args' and `args_size' if a nested call is in progress, see explanatory comment. See also tests/addcomma. * Makefile.am: Fix things so that gawk/pgawk built first, even if `make check' called before make. Add some commentary. Wed Nov 8 14:39:20 2000 Arnold D. Robbins * configure.in: Only add -rdynamic for linux. * dfa.h, dfa.c: upgraded to versions in grep 2.4.2. Tue Nov 7 18:17:17 2000 Arnold D.

Tue Oct 17 10:47:35 2000 Arnold D. Robbins * array.c (assoc_lookup): Reverted change that did dupnode of array indices. Creates significant problems if index is numeric value and CONVFMT changes. Added fix to set bucket->ahname->stfmt to -1 so that force_string never recalculates the string value, and also turned off NUM and turned on STR. See test/arynasty.awk. Mon Oct 16 12:21:26 2000 Arnold D. Robbins * All: Cleaned up various lint warnings for consistent phrasing. * awk.y (in_end_rule): New variable for warning about unredirected getline.

Robbins * awk.h, awkgram.y, configure.in, eval.c: enabled `for (i in_sorted array)' loops for those who are Strong In The Way Of The Source. So there. Mon Oct 2 10:09:32 2000 Arnold D. Robbins * io.c (do_close): make close(x) for non-open x return -1 and update ERRNO. close(FILENAME) no longer does anything magic; this is all for better consistency with other awks and is more logical, anyway. Thu Sep 28 17:27:16 2000 Arnold D. Robbins * io.c (close_one): Added a lint warning if it becomes necessary to start multiplexing fd's, per ancient suggestion from Scott Deifik, . Tue Sep 26 14:41:41 2000 Arnold D. Robbins * profile.c: Move enum for redirection placement to top of file, and make the value a parameter to pp_redir. Fix all the calls. This gets `|&' right everywhere. Sun Sep 24 16:38:04 2000 Arnold D. Robbins * awk.h (freenode): set the flags straight to UNINITIALIZED. * node.c (unref): Fix test for MALLOC|TEMP to test the actual flags, not zero. * builtin.c (format_tree): ala print and concat, dupnode the temp nodes from tree_evaling the arguments. See test/nasty2.awk. Mon Sep 18 10:16:58 2000 Arnold D. Robbins * awkgram.y (snode): Make match 3rd arg and close 2nd arg fatal errors if --tradtional. Thu Sep 14 12:22:42 2000 Arnold D.

Dupnode the strings ala do_print to get more consistent results. Compare gawk 3.0.6 to nawk/mawk on test/nasty.awk. Thanks to Andrew Sumner (andrewsumner@yahoo.com) for pointing this one out. Wed Sep 13 10:06:47 2000 Arnold D. Robbins * io.c (two_way_close_type): New enumerated type. (close_redir): New third param of type two_way_close_type. Add smarts to two-way case for different close types. Only remove it from the redir list if closing is for both ends. (gawk_pclose): Check that rp->iop != NULL before closing, all three versions. * awkgram.y (tokentab): Allow 2nd argument to close. (snode): Add lint warning. Sun Sep 10 14:16:10 2000 Arnold D.

Thu Sep 7 10:46:20 2000 Arnold D. Robbins * builtin.c (do_dcgettext): Per suggestion from Ulrich Drepper, make the awk interface: str = dcgettext(string [, domain [, category]]) Wed Sep 6 16:28:12 2000 Arnold D. Robbins Bring gettext features out to the awk level! * awk.h: Add declarations of new functions `do_dcgettext' `do_bindtextdomain', `set_TEXTDOMAIN' and variables `TEXTDOMAIN', `TEXTDOMAIN_node'. New NODETYPE enum `Node_TEXTDOMAIN'. * eval.c (nodetypes): add Node_TEXTDOMAIN at end. (set_TEXTDOMAIN): new function. (r_get_lhs): add case for Node_TEXTDOMAIN. * main.c (varinit): add entry for TEXTDOMAIN. * node.c (format_val): If INTLSTR use dcgettext of string and TEXTDOMAIN. * awkgram.y (tokentab): Add entries for "dcgettext" and "bindtextdomain". * builtin.c (do_dcgettext, do_bindtextdomain): new functions. Tue Sep 5 17:01:34 2000 Arnold D. Robbins * profile.c (pp_string_fp): Use lower case versions of isascii and isprint to avoid printing high-bit-set characters. Make it smarter to break strings at 70 chars or after embedded newline, for --gen-po. Fix the calls to it everywhere for new boolean option to yes/no break lines. * m4/strtod.m4: new file, defines GAWK_AC_FUNC_STRTOD_C89. * configure.in: GAWK_AC_FUNC_STRTOD_C89 call added * acinclude.m4: include strtod.m4. * acconfig.h: add entry for STRTOD_NOT_C89.

Avoids linker weirdness. Mon Sep 4 09:16:43 2000 Arnold D. Robbins * field.c (set_record): fix from Utz-Uwe Haus to make sure there's always enough room in the record. * builtin.c (nondec2awknum): Fix octal conversions to exit when hitting a non-digit, and not go to decimal. Make check for non-octal better. Based on bug report from Morris_Lee@tvratings.com. Sun Sep 3 13:52:11 2000 Arnold D. Robbins * builtin.c (format_tree): Allow positional parameters for %*.* kinds of things. Made octal/hex constants and strtonum on by default.

[print productions]: call the function. (snode): for do_sprintf, call count_args, set the count in the lnode. builtin.c (format_tree): new fourth arg is argument count. Add smarts to handle the `$' in a format. (do_sprintf): use new argument to format_tree. node.c (format_val): ditto. Sun Aug 13 11:10:41 2000 Arnold D. Robbins Changes from Alan J. Broder (ajb@woti.com): - Array third arg to match puts subtexts into the array: * awk.y (tokentab): "match" gets third arg, and lint warning * builtin.c (do_match): if third arg there, fill it with subtexts - New builtin sort function: * awk.h (do_sort): declared. * array.c (do_sort, dup_table, merge, merge_sort, assoc_from_list, assoc_sort_inplace): new functions. * eval.c (tree_eval): in debug code, make uninitialized var a warning, not a fatal error. Breaks too many things. Wed Aug 9 10:51:41 2000 Arnold D. Robbins * eval.c (func_call): Increment the exec_count on the function's node; this allows printing a call count for functions. profile.c (pp_func): print the count for functions. * ALL: Changed DEBUG to GAWKDEBUG in all gawk files, so that I don't get regex/dfa debugging. In some cases, changed memory-related stuff to MEMDEBUG. Still have work to do. * awk.h, node.c, profile.c: removed exec_count_init variable; code has been cleaned up to not need different values for profiling/not profiling. Thu Jul 5 21:10:59 2000 Arnold D. Robbins * eval.c (casetable): Removed the USE_PURE_ASCII stuff; it was never documented. Latin 1 forever. * main.c (main): only call `init_profiling' after arg parsing if `do_profiling' is still false.

Robbins * io.c (redirect): add lint warning when same file is used for > and >>. Thu Apr 22 15:05:30 1999 Arnold D. Robbins * array.c (assoc_lookup): Fix call to fatal to lintwarn instead. * node.c (r_force_number): Use `0 &&' to disable warnings about conversions: they're overzealous, methinks. Thu Apr 8 14:27:58 1999 Arnold D. Robbins New features for profiling: * awk.h (NODE): add `exec_count' member.

Robbins * Changes based on submission from Christos Zoulas at D.E. Shaw that adds the following features: - checking for use of uninitialized variables - checking if a string that's not a number converts to 0 - ability to load a dynamic library to add built-ins - VERSION variable (may or may not stay) Additional change: - --lint=fatal makes lint errors become fatal - LINT="fatal" has the same effect, any other positive value makes lint errors be just warnings * Makefile.in (includedir): new variable for gawk header files (ext.c, ext.o): new source and object files (OTHERS, extension): new directory for macro with example extension (install): install header files * acconfig.h (DYNAMIC): new macro, true if can do dynamic loading * array.c (assoc_lookup): new parameter `reference' is true if we want to do reference checking.

(optab): change for "lint" to allow optional argument. (lintfunc): definition. (main): add case in option processing for --lint. (varinit): add entries for VERSION and EXTENSION. * node.c (r_force_number): checks that string really is a number.

(Makefile.in): changed to ref patchlev.h where needed. Sat Nov 7 21:29:52 1998 Arnold D. Robbins * eval.c (r_get_lhs): case Node_field_spec. Fix the lint warnings for field reference of null string or non-numeric value. When turned on, $0 generated a warning! Oops. Thu Nov 5 16:58:38 1998 Arnold D. Robbins * main.c (init_fds): new function to pre-open 0, 1, and 2 on /dev/null if they're not open. Robustness, more or less.

Robbins * awk.h (reisstring): new prototype. * re.c (reisstring): new function, returns true if the re did a simple string match. This is rather simplistic in its logic. * io.c (get_a_record): in the case that RS is a regexp, AND the re matched at the exact end of the buffer, add a call to `reisstring' in case it's a simple string match. If so, we don't need to read more into the buffer because we don't have a regex like `x.*y' that might extend longer. This should be very helpful for interactive /inet clients where something like `RS = "\r\n"' happens. Thu Aug 13 22:07:40 1998 Arnold D. Robbins * io.c (socketopen): fixes from Juergen Kahrs to socket opening code for "any host". Tue Jul 14 19:02:33 1998 Arnold D.

Robbins * io.c (devopen): for /inet, require that local and remote ports and the remote hostname be there, and that `any' be used for a port if they don't care. Thu May 21 14:13:46 1998 Arnold D. Robbins * node.c (parse_escape): Add warning that is always on for \q for any unknown q inside string or regex constant. I got bit by this myself once too often. Or else I'm just getting old and senile. Mon May 4 12:42:49 1998 Arnold D. Robbins * awk.h (NODETYPE): Sorted the Node_xxx entries for the builtin variables. Gotta look nice, don't we? * eval.c (nodetypes): ditto. (genflags2str): added code to check that we don't overflow the static buffer.

(redirect): better error message in default case, add code for Node_redirect_twoway. (socketopen): new function. (iop_open, devopen): add recognition of `/inet/...'. (two_way_open): new function. Sat Dec 13 21:15:07 1997 Arnold D. Robbins * awk.h (struct node): new member, `param_list' in union `x', becomes `node->parmlist' in the code. * awk.y (func_install): rearranged a bit, to build up a list of the function parameter names and to save it in the `parmlist' field. * eval.c (push_args): new parameter, `varnames', which is the list of variable names. Use this to set the vname field of each parameter's value as it's created. Special case arrays to include where they came from, mainly for array vs. scalar diagnostics. (r_tree_eval): don't set the `vname' field for parameters. (pop_fcall): free the `vname' field if it's an array. (func_call): pass in the `parmlist' field to call of push_args().

Robbins * node.c (parse_escape): Add lint warning for unrecognized escape sequences. Mon Dec 6 15:17:34 1999 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * io.c (close_redir): Don't munge errno between setting it and using it. Wed Oct 6 17:47:47 1999 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 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 * 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 * 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 * Release 3.0.4: Release tar file made. This time for sure. Wed Jun 30 16:10:11 1999 Arnold D. Robbins * awk.h: add include of , 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 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 * 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 * BETA Release 3.0.46: Release tar file made. Wed Jun 2 14:36:24 1999 Arnold D. Robbins * 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 * BETA Release 3.0.45: Release tar file made. Tue May 25 16:32:37 1999 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * BETA Release 3.0.44: Release tar file made. Sun May 2 18:25:43 1999 Arnold D. Robbins * 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 * 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 * 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 * BETA Release 3.0.43: Release tar file made. Tue Apr 13 19:02:20 1999 Arnold D. Robbins * 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 * 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 * BETA Release 3.0.42: Release tar file made. Sun Nov 15 21:05:39 1998 Arnold D. Robbins * 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 * BETA Release 3.0.41: Release tar file made. Tue Nov 3 16:24:35 1998 Arnold D. Robbins * 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 * 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 * 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 * 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 * BETA Release 3.0.40: Release tar file made. Mon Jul 27 10:14:33 1998 Arnold D. Robbins * node.c (parse_escape): Remove assignment with side effects from ISXDIGIT test. Thanks to "Mihai T. LAZARESCU" for pointing this out. Mon Apr 27 11:31:32 1998 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * awk.y [variable]: fix case for subscript if $3 == NULL. Sun Jul 27 22:47:30 1997 Arnold D. Robbins * awk.y (get_src_buf): don't close file if it's stdin. Sun Jul 27 22:47:15 1997 Pat Rankin * 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 * 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 * 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 . Thu Jun 19 19:00:40 1997 Arnold D. Robbins * 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 * 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 * Release 3.0.3: Release tar file made. Wed May 14 08:06:08 1997 Arnold D. Robbins * io.c (do_close): add lint warning if closing something that isn't open. Tue May 13 12:14:12 1997 Arnold D. Robbins * 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 * io.c [MSC_VER]: add cases for WIN32. * regex.c [MSC_VER]: add cases for WIN32. Sun May 11 07:04:01 1997 Arnold D. Robbins * 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 * io.c (get_a_record): fix casetable indexing with cast to int. Keeps Michal happy. Tue May 6 16:40:19 1997 Arnold D. Robbins * eval.c (func_call): removed unneeded variables. Mon May 5 21:17:37 1997 Pat Rankin * 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 * regex.h, regex.c: merge with current GLIBC version. Mon May 5 06:33:47 1997 Pat Rankin * 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 * 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 * 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 * dfa.c: misc changes for really pedantic SGI compilers. * builtin.c: bracket defs of random() etc for GLIBC. * random.c: bracket whole file for GLIBC. * configure.in: extra goop for GETPGRP test for VMS POSIX. * custom.h [VMS]: remove hard definition of GETPGRP_VOID. Fri Apr 18 07:55:47 1997 Arnold D. Robbins * BETA Release 3.0.34: Release tar file made. Tue Apr 15 21:35:45 1997 Arnold D. Robbins NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE! * acconfig.h [NONDECDATA]: new macro. * awk.h: add decl of do_strtonum. * awk.y (tokentab): add entry for strtonum function. * builtin.c (do_strtonum): new function. * configure.in (non-decimal-data): new --enable-* option. * node.c (r_force_number): change to allow non-decimal data inside ifdef NONDECDATA. Tue Apr 15 06:32:50 1997 Pat Rankin * missing/strftime.c (malloc, realloc, getenv, strchr): only declare these when STDC_HEADERS is not defined. : 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 * Makefile.in [COMPFLAGS]: per suggestion from Karl Berry, put $(CFLAGS) last. Tue Apr 8 23:54:46 1997 Arnold D. Robbins * 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 * awk.h: Add decls of new routines do_compl() and set_loc(). * awk.y (tokentab): add entry for "compl" function. * 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(). * 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 * 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 * custom.h [_SEQUENT_]: undef HAVE_MMAP. Wed Mar 26 09:08:16 1997 Arnold D. Robbins * io.c (iop_alloc): fix definition to make it static. Mon Mar 24 23:09:07 1997 Arnold D. Robbins * 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 * 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 * 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 * awk.y (dup_parms): robustified against parameter errors. Sun Mar 16 21:31:40 1997 Arnold D. Robbins 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 * 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 * 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 * Misc changes from Katsuyuki Okabe : * 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 * 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 * 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 * 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 * 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 * getopt.h, getopt.c, getopt1.c: replaced with new versions from GLIBC 2. Sun Jan 19 23:37:03 1997 Arnold D. Robbins * 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 * io.c (mmap_get_record): Fix return value if file ends without record separator. Fri Jan 3 19:57:16 1997 Pat Rankin * 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 * Release 3.0.2: Release tar file made. Wed Dec 25 11:17:32 1996 Arnold D. Robbins * 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 * custom.h (#if VMS_POSIX): Define GETPGRP_VOID. Fri Dec 20 08:59:55 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * Release 3.0.1: Release tar file made. Tue Dec 10 22:39:41 1996 Arnold D. Robbins * Makefile.in (dist): add dependency on `info'. Remove line that does makeinfo. (install): use $(LN) not $(LN_S) to link gawk gawk-version. Sun Dec 8 07:53:44 1996 Arnold D. Robbins * 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 * configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh. Tue Nov 26 22:42:00 1996 Arnold D. Robbins * PORTS: Updated list of systems. * Makefile.in (install): Fix some typos and add some improvements for Ultrix. Sun Nov 24 22:16:26 1996 Arnold D. Robbins * builtin.c (do_printf): if no args, fatal error. Return silently if --traditional. Thu Nov 7 20:54:43 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * configure.in: remove test for random. * Makefile.in: add random.c to list of files always compiled. * missing.c: remove HAVE_RANDOM test. * builtin.c: remove ifdef's for HAVE_RANDOM. [GAWK_RAND_MAX]: use constant we know works with our random(). * random.c: new file - moved from missing/ directory. Wed Oct 23 19:46:01 1996 Pat Rankin * builtin.c (do_tolower, do_toupper): Add `unsigned char *' casts. Tue Oct 22 21:27:52 1996 Arnold D. Robbins * 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 * main.c (copyleft): update copyright date to 1996. too many files to list: update copyright date to 1996. Sun Oct 20 12:21:09 1996 Arnold D. Robbins * awk.y, dfa.c, eval.c, io.c, re.c: added various FIXME comments. Sat Oct 19 22:06:42 1996 Arnold D. Robbins * eval.c (nodetype2str): make static, add prototype. * field.c (sc_parse_field): cast array subscripts to int to shut up gcc warnings. * gawkmisc.c: add prototype for xmalloc. * awk.h: add prototype for getredirect. * builtin.c (do_fflush): remove extern decl of getredirect. * io.c (get_a_record, mmap_get_record): change decl of rs to int, to shut up gcc warnings. * awk.y (isassignable): add a default to switch to quiet gcc. * getopt.c (_getopt_internal): give default value to `indfound'. Fri Oct 18 09:00:49 1996 Arnold D. Robbins * regex.h [RE_SYNTAX_AWK]: add RE_CONTEXT_INDEP_ANCHORS. Thu Oct 17 22:32:55 1996 Arnold D. Robbins * aclocal.m4 [AM_SANITY_CHECK_CC]: added. * configure.in: use it. Thu Oct 17 21:43:25 1996 Arnold D. Robbins * configure.in: add checks for locale.h and setlocale(). 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, to get other charsets right in different locales. Wed Oct 16 21:32:53 1996 Arnold D. Robbins * 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. Wed Oct 16 21:22:08 1996 Arnold D. Robbins * Makefile.in [MISC]: removed TAGS and tags (local-distclean): added TAGS and tags (maintainer-clean): removed TAGS and tags Wed Oct 16 12:28:43 1996 Arnold D. Robbins * 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 * regex.c: updated to Emacs 19.34b base. Sun Oct 6 21:57:34 1996 Arnold D. Robbins * 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 * 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 * 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 * awk.h (INT_MAX): Remove unused symbol. Mon Sep 30 22:19:11 1996 Arnold D. Robbins * 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 * 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 * alloca.c (NULL): don't define if has already done so. Fri Sep 20 11:54:31 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * Makefile.in (install): correct use of $(INSTALL_PROGRAM). Thu Aug 8 23:29:43 1996 Arnold D. Robbins * 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 * 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 * 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 * io.c (O_ACCMODE): define it if doesn't. Mon Jul 29 12:02:48 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * regex.h, regex.c: upgraded to changes from Emacs 19.31. Fri May 17 08:46:07 1996 Arnold D. Robbins * 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 * Makefile.in (awklib/all): now depends on gawk, fixes problem with parallel make. Tue May 14 15:02:52 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * 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, . Thu Mar 7 08:08:51 1996 Arnold D. Robbins * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 3.0.0 polished up and release tar file made. Wed Dec 27 11:46:16 1995 Arnold D. Robbins * 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 * 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 * 2.90.0 released to porting group. Fri Aug 18 12:43:31 1995 Arnold D. Robbins * ChangeLog created.
