This is a change to default values; the YYMAXDEPTH and YYSTACKSIZE symbols have "always" been overridable by applications, but rarely needed to do this. RedHat began using the FreeBSD source in 2000, and switched to this source in 2007 using the 20050813 snapshot. RedHat #743343 misattributed the change in default stacksize to a regression in byacc, but did not report the issue upstream. * package/debian/changelog, VERSION, package/byacc.spec: bump 2013-09-07 Thomas E.

Dickey * aclocal.m4: split-out CF_CC_ENV_FLAGS from CF_ANSI_CC_CHECK to avoid losing it in Adrian's suggested changes. * aclocal.m4: CF_CLANG_COMPILER - check if the given compiler is really clang. * aclocal.m4: add check for clang to CF_GCC_WARNINGS. modify CF_GCC_WARNINGS to work around old gcc warning: ncurses change to (try to) use gnatgcc exposed gnatgcc 2.8.1 on my Sarge system (versus 3.3.5 for the normal gcc). The 2.8.1's pointer-arithmetic checks fell afoul of gcc's misuse of void* in string.h; work around by excluding that check for pre-3.x compilers. * aclocal.m4: modify CF_GCC_ATTRIBUTES so that autoheader is able to see the definitions provided by this macro. use AC_DEFINE_UNQUOTED() in CF_GCC_ATTRIBUTES rather than appending to confdefs.h, since long-ago concern about the ability to pass-through parameterized macros appears to be not a problem, testing with 2.13 and 2.52 2012-10-03 Adrian.Bunk * aclocal.m4: add parameter to AC_DEFINE_UNQUOTED() to allow it to be recognized by autoheader, updated macros: CF_CHECK_CACHE CF_DISABLE_LEAKS CF_MKSTEMP CF_MIXEDCASE_FILENAMES CF_NO_LEAKS_OPTION 2012-10-03 Thomas E.

Dickey * package/debian/changelog, package/byacc.spec, VERSION: bump * reader.c: some versions of gcc may warn that bp is not set in mark_symbol, e.g., if GCC_NORETURN is not handled; appease the compiler. * reader.c: use the declared types Assoc_t and Value_t in some places where compiler only cared about char versus short. * reader.c: use TMALLOC() and TREALLOC() macros to simplify allocation/reallocation (no object change) * defs.h: add fallbacks for GCC_NORETURN and GCC_UNUSED to make it simpler for *BSD packagers to build without configure script. Also remove duplicate declaration of pure_parser variable (prompted by patch by Baptiste Daroussin).

This allows for the use of YYPARSE_PARAM, by having the output that checks for YYPARSE_PARAM to be defined come after the C code block in the definitions section of a yacc file. Implement support for YYLEX_PARAM, similar to bison. This is useful for support for building reentrant lexers with flex. Fix a compatibility issue with bison's pure-parser option. Bison defines yylex as sending at least one parameter, &yylval, as the first parameter and doesn't seem to have an easy way to remove that parameter. This on the other hand is rather convenient to support saving to yylval from flex when building reentrant lexers and parsers. Add support for the %parse-param and %lex-param directives used in bison. This change bears some similarity to NetBSD's changes to byacc at http://www.mail-archive.com/source-changes-full@netbsd.org/msg08143.html Bison allows for POSIX yacc emulation via a yacc directive in the yacc file, and also via a command line switch. Implement this feature as a no-op for byacc, since byacc is designed to be POSIX yacc compatible anyway. This allows for better compatibility with yacc sources written for bison. 2010-06-07 Thomas E.

Dickey * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c: better implementation of YYPARSE_PARAM, using YYPARSE_DECL() macro * VERSION: bump * skeleton.c: better implementation of YYPARSE_PARAM, using YYPARSE_DECL() macro * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c, skeleton.c: change YYRECOVERING to YYRECOVERING(), for compatibility with other yacc's. * configure: regen'd * configure.in: add -Wwrite-strings to warnings * test/ftp.tab.c, test/grammar.tab.c, test/calc.tab.c, test/error.tab.c: add YYPARSE_PARAM and YYPARSE_PARAM_TYPE * skeleton.c: add YYPARSE_PARAM (bison) and YYPARSE_PARAM_TYPE (FreeBSD) features. * main.c, defs.h, output.c, skeleton.c, symtab.c, error.c, reader.c: fixes for gcc -Wwrite-strings * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c: generate the tables as static-const (this is an interface change) * output.c: realign columns in start_table() * output.c: generate the tables as static-const (this is an interface change) * output.c: reorder functions to eliminate forward-references * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c: remove 'register' keywords 2008-08-26 Thomas E. Dickey * warshall.c, verbose.c, symtab.c, skeleton.c, reader.c, output.c, mkpar.c, main.c, lr0.c, lalr.c, graph.c, error.c, closure.c: remove 'register' keywords 2008-08-25 Thomas E. Dickey * test/ftp.tab.c: regen'd * reader.c: improve the left-curly fix by testing after blanks, to avoid having a " {" at the beginning of a line. * test/error.tab.c, test/grammar.tab.c: regen'd * output.c: move the remaining newline-counting into write_XXX functions. * test/calc.tab.c: regen'd * output.c: simplify part of the output_file formatting using new functions, e.g., start_int_table(), output_newline(). * reader.c: modify copy_action() to indent the first character, it if is is left-curly brace. That makes the output look more like the original, as well as makes it simpler to edit (not confuse editors which look for a left-curly in the first column as if it were the beginning of a function). * skeleton.c: minor fixes to avoid gcc -Wconversion warnings * output.c: align the #define's produced for "-p" option * test/run_test.sh: use the "-p" option for better coverage. * output.c: simplify output_prefix() with new define_prefixed() * skeleton.c: include string.h, for memset() change stack size to unsigned to fix gcc -Wconversion warnings. * VERSION: bump to 2008/8/25 * makefile.in: add dependency on VERSION file. 2008-08-24 Thomas E. Dickey * VERSION: bump * lalr.c: improved memory-leak checking by freeing data in includes[] * test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c, test/calc.tab.c: update to match skeleton-change * configure: regen'd * skeleton.c: Add fix for stack discussed http://undeadly.org/cgi?action=article&sid=20080708155228 and applied http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/yacc/skeleton.c.diff?r1=1.28&r2=1.29 * aclocal.m4: resync with my-autoconf (no major changes) 2008-07-24 Thomas E. Dickey * package/pkgsrc/Makefile, package/pkgsrc/distinfo: scripts from NetBSD pkgsrc, for test-builds 2008-03-14 Thomas E. Dickey * config.sub: update to 2008-03-08 * config.guess: update to 2008-03-12 2007-05-09 Thomas E. Dickey * main.c: close graph, verbose files if opened, on exit. * main.c: audit memory leaks - valgrind reported some memory still in use on exit. * lalr.c, output.c, reader.c, mkpar.c, lr0.c: add hook for auditing memory leaks * defs.h: add hooks for auditing memory leaks * configure: regen'd * configure.in: use CF_DISABLE_LEAKS, which combines --disable-leaks, --with-valgrind, --with-dbmalloc and --with-dmalloc * aclocal.m4: add CF_DISABLE_LEAKS and CF_WITH_VALGRIND * aclocal.m4: improve version-checking in CF_GCC_VERSION rework dbmalloc/dmalloc options using CF_NO_LEAKS_OPTION macro * VERSION: 2007/5/9 * main.c: file_prefix did not always have a trailing null. 2007-03-25 Thomas E. Dickey * mkdirs.sh: improved version for "make -j" 2006-12-22 Thomas E. Dickey * config.guess: update to 2006/12/22 2006-12-08 Thomas E. Dickey * config.sub: update to 2006/12/08 2005-08-13 Thomas E. Dickey * main.c: add -V to usage message * makefile.in: remove -t option from ctags * VERSION: 2005/8/13 2005-08-13 schmitz * main.c: Sylvain Schmitz: modify the '-o' option to work like bison's, which sets the file-prefix. 2005-08-13 Matt.Kraai * output.c: Debian #322858 (don't close union_file, which contained data). This feature is used in groff. 2005-08-13 Thomas E. Dickey * configure: regenerated * aclocal.m4: improve checks for Intel compiler warnings 2005-06-25 Thomas E. Dickey * config.sub: update to 2005/6/2 * config.guess: update to 2005/5/27 2005-05-05 Thomas E. Dickey * defs.h: add a fallback for GCC_UNUSED 2005-05-04 Thomas E. Dickey * makefile.in: add "." to include-path to pickup config.h * reader.c: apply fix suggested by Steve Dum for end_rule() in Redhat Bugzilla #112617. * output.c: correct a limit check in pack_vector() - report/analysis by William Evans * main.c: exit after printing version. Otherwise "yacc -V" will exit with an erro after printing the usage message. * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c: regenerated after skeleton-changes * skeleton.c: replace a few -1's with YYEMPTY * skeleton.c: delete yynewerror (no one uses it any more, and it just makes compiler warnings) * skeleton.c: adapt yygrowstack() and related definitions from FreeBSD * test/run_test.sh: filter out lines with YYPATCH, since that will change with each update * yacc.1: add -V option * main.c: add -V option to print the version. simplify option-parsing by moving the duplicate logic for setting flags into new function setflag(). * skeleton.c: move the actual definition of YYMAJOR and YYMINOR to defs.h (as numbers). add YYPATCH here so it can be tested by applications. * defs.h: add macros to define VERSION in terms of the (numeric) YYMAJOR, YYMINOR and YYPATCH symbols. * lalr.c, lr0.c, mkpar.c, defs.h, closure.c, warshall.c, output.c, verbose.c, graph.c, reader.c, main.c, symtab.c: reduce externs by making static the procedures that are not referenced outside the module in which they are defined. * makefile.in: the VERSION file holds the patch-date. Define YYPATCH, so this will be compiled into the skeleton. * VERSION: patch-level for byacc * main.c: add "-o" to usage message. It is too long for a single line; rewrite usage() to show one option per line. 2005-05-03 Thomas E. Dickey * main.c: add -o option, to work with scripts that assume bison. simplify create_file_names() with a macro. simplify done() with a macro. adapt fix from FreeBSD for signal race, e.g., if done() is interrupted by onintr(), do not flush output via exit(), but use _exit() instead. * defs.h: remove unnecessary externs for main.c * yacc.1: add -o option * graph.c: remove unused parameter * mkpar.c, defs.h, reader.c: add support for "%expect", a bison feature from FreeBSD sources * lr0.c, reader.c, main.c, skeleton.c, graph.c, symtab.c, closure.c, mkpar.c, lalr.c, error.c, warshall.c, verbose.c, output.c: indent'd * configure: regenerated for 2005/5/5 * aclocal.m4: miscellaneous updates (adds CF_INTEL_COMPILER) 2005-04-27 schmitz * defs.h, graph.c, lr0.c, main.c, makefile.in, reader.c, yacc.1: Sylvain Schmitz : add graphical output of the LALR(1) automaton for graphviz, associated with command-line option `-g' 2005-04-16 Thomas E.

Dickey * test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c: updates due to adding yyparse() prototype * configure: RCS_BASE * configure.in: add AC_ARG_PROGRAM to make --program-prefix, etc., work. * makefile.in: first cut of script to support --program-prefix * configure.in: reorder AC_INIT/AC_CONFIG_HEADER to make this "work" with autoconf 2.52 * makefile.in: modify so DESTDIR works * makefile.in: use EXEEXT and OBJEXT * configure.in: use CF_PROG_EXT generate a config.h * defs.h: make this use the generated config.h * skeleton.c: add a forward-reference for yyparse() * aclocal.m4: add CF_CHECK_CACHE, needed for CF_PROG_EXT * yacc.1: remove the discussion of TMPDIR since it is obsolete * skeleton.c: fix a couple of minor compiler-warnings in the skeleton * defs.h: remove action_file_name, etc., since we use tmpfile() now. * main.c: use tmpfile() for opening the working files. This quiets a warning advising the use of mkstemp(). * output.c: Do not close temporary-files here, since they are opened with tmpfile(). Just rewind them, and they're ready to read back the data stored in them. * test/grammar.output, test/grammar.tab.c, test/grammar.tab.h: RCS_BASE * test/yacc/grammar.output, test/yacc/grammar.tab.h: reference output for testing * makefile.in: turn on "make check" rule * test/calc.output: RCS_BASE * test/yacc/calc.output: reference output for testing * test/run_test.sh, test/calc.tab.h: RCS_BASE * test/yacc/calc.tab.h: reference output for testing * test/ftp.tab.c: yyparse() is now yyparse(void) * test/calc.tab.c: RCS_BASE * test/error.tab.c: yyparse() is now yyparse(void) * test/README: RCS_BASE * yacc.1: various typography fixes prompted by Debian #100947 * aclocal.m4, makefile.in, configure.in: RCS_BASE * README: updated to note that this is not the original 2004-03-24 Thomas E.
