+
+ Fix memory leaks in scanners generated by at least Flex 2.5.9 and
+ later. Reported by Paul Eggert in
+ <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
+ * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
+ * src/scan-code.l (translate_action): Don't bother invoking
+ yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
+ (code_scanner_free): Instead of invoking
+ yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
+ which frees more.
+ * src/scan-gram.l (gram_scanner_free): Likewise.
+ * src/scan-skel.l (scan_skel): Likewise.
+
+2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/files.c (tr): Change return type to void.
+ * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
+ has been called previously for the same key.
+ (muscle_find): Return storage instead of value so that
+ --enable-gcc-warnings doesn't produce warnings that the return discards
+ const. aver that the value and storage are the same since storage
+ could potentially be NULL when value is not.
+ * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
+ same as 0.
+
+2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
+ the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
+ us a slightly cleaner distribution, and also works.
+ * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
+ gnulib changes.
+
+2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Don't let Bison leak memory except when it complains.
+ * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
+ (spec_defines_file, dir_prefix): Now char *, not const char *,
+ since they are freed.
+ * src/files.c: Likewise.
+ (all_but_ext, all_but_tab_ext, src_extension, header_extension):
+ Likewise.
+ (tr): Now operates in-place. All uses changed.
+ (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
+ values.
+ (compute_file_name_parts, compute_output_file_names): Don't store
+ read-only data in variables that will be freed.
+ (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
+ src_extension, and header_extension.
+ (output_file_names_free): New public function to free
+ spec_verbose_file, spec_graph_file, spec_defines_file,
+ parser_file_name, and dir_prefix.
+ * src/getargs.c (getargs): Don't store read-only data in variables that
+ will be freed.
+ * src/main.c (main): Invoke output_file_names_free, code_scanner_free
+ (which previously existed but was unused), and quotearg_free.
+ * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
+ * src/muscle_tab.c: Likewise.
+ (muscle_entry): Make the value char const *,
+ and add a new storage member that is char * and can be freed.
+ (muscle_entry_free): New private function.
+ (muscle_init): Use it instead of free.
+ (muscle_insert, muscle_grow): Update and use new storage member.
+ (muscle_code_grow): Free the string passed to muscle_grow
+ since it's not needed anymore.
+ * src/parse-gram.y (%union): Make `chars' member a `char const *', and
+ add a new `char *code' member.
+ ("{...}"): Declare semantic type as code.
+ * src/scan-code.h (translate_rule_action):
+ (translate_symbol_action, translate_code, translate_action): Return
+ `char const *' rather than `char *' since external code should not free
+ these strings.
+ * src/scan-code.l: Likewise.
+ * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
+ which is "{...}" in the parser.
+ * tests/Makefile.am (maintainer-check-valgrind): Set
+ VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
+ Valgrind.
+ * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
+ complain.
+ * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
+ expecting a non-zero exit status sets --leak-check=summary and
+ --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
+ this case, and we don't want to hear about it.
+
