dbfcf7a89f scanner: restore a missing start condition
$ flex src/scan-skel.l
src/scan-skel.l:145: multiple <<EOF>> rules for start condition SC_AT_DIRECTIVE_ARGS
src/scan-skel.l:145: multiple <<EOF>> rules for start condition SC_AT_DIRECTIVE_SKIP_WS
This is warning, and it seems there are no means to make it an error.

* src/scan-skel.l: Restore the start-condition INITIAL for an <<EOF>>
clause.

e969014232 global: remove unnecessary horizontal tabs.
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository.  Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.

84f6a6ca70 Don't use IF_LINT in Bison sources.
It creates unnecessary differences between the sources that Bison
maintainers build and test (given that maintainers normally
configure with --enable-gcc-warnings) and the sources that Bison
users build.  Instead, use PACIFY_CC, which doesn't.  This change
fixes compiler warnings reported by Tys Lefering at
<http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
* configure.ac: Don't AC_DEFINE lint regardless of the configure
options.  This change affects imported gnulib sources, where
IF_LINT still appears and depends on lint.
* src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
PACIFY_CC.
* src/system.h (IF_LINT): Remove cpp macro.
(PACIFY_CC): New cpp macro.

f39ab2869c portability: fix several issues with M4 subprocess.
M4's output pipe was not being drained upon fatal errors during
scan_skel.  As a result, broken-pipe messages from M4 were seen
on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
failure in the test suite.  The problem was that, on platforms
where the default disposition for SIGPIPE is ignore instead of
terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
then reported it.  However, there's some sort of race condition,
because the new test group occasionally succeeded.
Reported by Albert Chin at
<http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.

There were also problems with the test suite livelocking on
Tru64 5.1b.  Reported by Didier Godefroy at
<http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
Switching to create_pipe_bidi suggested by Akim Demaille.

To attempt to solve both of these problems, switch to gnulib's
create_pipe_bidi and register M4 process as a slave.  Along the
way, clean up file name conflict handling, which was affected by
the broken-pipe problem before the switch.
* NEWS (2.4.2): Document.
* THANKS (Didier Godefroy): Add.
* bootstrap.conf (gnulib_modules): Add pipe.
* gnulib: Update to latest to make sure we have all the latest
fixes.
* lib/local.mk (lib_libbison_a_SOURCES): Remove subpipe.h and
subpipe.c.
* po/POTFILES.in (lib/subpipe.c): Remove.
* src/files.c (compute_output_file_names): Update invocations
of output_file_name_check.
(output_file_name_check): In the case that the grammar file
would be overwritten, use complain instead of fatal, but replace
the output file name with /dev/null.  Use the /dev/null solution
for the case of two conflicting output files as well because it
seems safer in case Bison one day tries to open both files at
the same time.
* src/files.h (output_file_name_check): Update prototype.
* src/output.c (output_skeleton): Use create_pipe_bidi and
wait_subprocess.  Assert that scan_skel completely drains the
pipe.
* src/scan-skel.l (at_directive_perform): Update
output_file_name_check invocation.
* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the
grammar file actually isn't overwritten.
(Conflicting output files: -o foo.y): Update expected output.
* tests/skeletons.at (Fatal errors but M4 continues producing
output): New test group.

* src/files.h (output_file_name_check): Update prototype.
* src/output.c (output_skeleton): Use create_pipe_bidi and
wait_subprocess.  Assert that scan_skel completely drains the
pipe.
* src/scan-skel.l (at_directive_perform): Update
output_file_name_check invocation.
* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the
grammar file actually isn't overwritten.
(Conflicting output files: -o foo.y): Update expected output.
* tests/skeletons.at (Fatal errors but M4 continues producing
output): New test group.

8d90395dd7 Pacify "gcc -Wunused" for the input function from Flex.
Reported by Alex Rozenman.  This warning shows up with gcc-4.3.0
and later.
* src/scan-code.l: Add "%option noinput", which I cannot find in
the Flex manual, but which Flex has supported since at least as
far back as 2.5.4.  However, if any of our developers still use
Flex 2.5.4, they'll need to stop configuring with
--enable-gcc-warnings because "%option noinput" didn't work
correctly until Flex 2.5.6.
* src/scan-gram.l: Likewise.
* src/scan-skel.l: Likewise.

0305d25eb0 Remove src/Makefile.am.
* src/Makefile.am: Rename as...
	* src/local.mk: this.
	Prefix all the paths with src/.
	(AUTOMAKE_OPTIONS): Build object files in the sub dirs.
	(AM_CPPFLAGS): Find find in builddir/src.
	(YACC): Move the flags into...
	(AM_YFLAGS): here.
	* maint.mk (sc_tight_scope): Disable.
	It used to bounce to the version in src/Makefile.am which is now
	part of this very Makefile.
	* Makefile.am, configure.ac: Adjust.
	* src/scan-code-c.c, src/scan-code.l: We can no longer rely on
	include "..." to find files "here": we are no longer in src/, so
	qualify the includes with src/.
	* doc/Makefile.am (PREPATH): No longer include the top_builddir
	prefix.
	(.x.1): Adjust to be able to create src/foo from the top level
	Makefile, instead of going bounce to src/Makefile the creation of
	foo.

7dc4a6940c Fix some error-reporting macro bugs.
* data/bison.m4 (b4_cat): New.
(b4_error, b4_error_at): Use b4_cat to send error directives directly
to stdout so they don't become arguments to other macros.  Update
comments and add examples.
(b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
add examples.
(b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
after printing the error directive so that M4 doesn't report subsequent
problems that are induced by this problem.
* src/scan-skel.l: Recognize @` digraph outside of directive arguments
instead of just in them.  Recognize @\n in both places.  Both expand to
the empty string.  Needed by b4_cat.
* tests/skeletons.at (Complaining during macro argument expansion):
New test case.
(Fatal errors make M4 exit immediately): New test case.

3eb82471fa Clean up.
* src/scan-skel.l (at_directive_perform): Add at_directive_argc and
at_directive_argv arguments so these no longer have to be global
variables.  Also, update the implementation for the following changes.
(fail_for_at_directive_too_many_args,
fail_for_at_directive_too_few_args): Add at_directive_name argument.
(at_directive_name): Remove as at_directive_argv[0] will be used for
this now.
(AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
for the directive name.
(at_directive_argc, at_directive_argv): Make these local within
skel_lex instead of global.
(INITIAL): Update directive start action for above changes.
(SC_AT_DIRECTIVE_ARG): Rename to...
(SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
(SC_AT_DIRECTIVE_SKIP_WS): Update.
(scan_skel): Move yylex_destroy to...
(skel_scanner_free): ... here.
* tests/skeletons.at (installed skeleton file name): Rename to...

d4bdb91677 Implement @gettext<...@> directive to call gettext from skeletons. It
can be used anywhere including inside arguments of directives of the
form @foo(...@).  Eventually, it should be possible to write an
xgettext-like utility to extract @gettext<...@> text from skeletons.
* data/bison.m4 (b4_check_user_names): Use @gettext<...@> when invoking
b4_warn_at since b4_warn_at doesn't invoke gettext anymore.
* data/glr.cc, data/lalr1.cc: Likewise but for b4_fatal and
b4_complain reporting a push-parsing request or a missing %defines.
* src/scan-skel.l (INITIAL): Recognize `@gettext<' to start...
(SC_AT_GETTEXT_ARG): ... this new start condition where gettext is
invoked.
(SC_AT_DIRECTIVE_ARG): Rename to...
(SC_AT_DIRECTIVE_ARGS): ... this, and recognize `@gettext<' to start
SC_AT_GETTEXT_ARG.
(at_directive_perform): Don't invoke gettext for @warn(...@),
@warn_at(...@), etc.  Instead, let the skeletons decide what should be
passed to @gettext<...@>.
* tests/skeletons.at (@gettext<...@>): New test case.

* tests/skeletons.at (installed skeleton file name): Rename to...
(installed skeleton file names): ... this.

3fc65ead4d Provide warn_at, complain_at, and fatal_at function callbacks to the
skeletons, and use this for %code qualifier complaints.
* data/bison.m4 (b4_error_at): New, invoked by...
(b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
@fatal_at(...@) directives.
(b4_check_percent_code_qualifiers): Rewrite to expect locations for
qualifiers in b4_used_percent_code_qualifiers and to use
b4_complain_at.
* src/location.c, src/location.h (boundary_set_from_string): New global
function.
* src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
function.
* src/parse-gram.y (grammar_declaration): Add locations for qualifiers
to b4_used_percent_code_qualifiers.
* src/scan-skel.l (fail_for_at_directive_too_few_args): New static
function.
(AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
(lineno): Rename to...
(out_lineno): ... this so I don't misunderstand it again.
(SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
here; these newlines are in the input but not the output file.
(SC_AT_DIRECTIVE_ARG): Likewise.  Extract directive execution to...
(at_directive_perform): ... this new static function, and add handling
of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
directives.
* tests/input.at (Reject bad %code qualifiers): Update test output with
locations and extend.

* tests/output.at (Output file name: [, Output file name: ]): Remove
bogus comment about these tests failing.

08af01c2fc Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
unreliable -- especially when they're hidden inside another macro.
* data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
data/c.m4: Remove m4_divert(-1).
* data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
m4_divert_push(0) and m4_divert_pop(0).
* data/output.c (output_skeleton): Don't add an m4_divert_push(0) and
an m4_wrap([m4_divert_pop(0)]) to the M4.  Diversion -1, which is
pushed and popped by m4sugar, should be first on the stack.

Provide warn, complain, and fatal function callbacks to the skeletons.
This provides more flexibility than m4_fatal, improves the error
message format, and captures messages for translation.  Discussed
starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
* data/bison.m4 (b4_error): New, invoked by...
(b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
directives.  Because these M4 macros might be called when the current
diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
the previous removal of uses of m4_divert, which caused trouble.
(b4_check_percent_code_qualifiers): Use b4_complain instead of
m4_fatal to report unrecognized %code qualifiers.
* data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
push parser requests.
* data/glr.c: Use b4_complain instead of m4_fatal to report
non-deterministic push parser requests.
Update @output usage to @output(...@) form.
* data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
report missing %defines.  Update @output usage to @output(...@) form.
* data/location.cc, data/push.c, data/yacc.c: Update @output usage to
@output(...@) form.
* src/main.c (main): Invoke skel_scanner_free.
* src/scan-skel.h (skel_scanner_free): Prototype new function.
* src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
obstack_for_string from flex-scanner.h.
(YY_DECL): Use to declare skel_lex static.
(decode_at_digraphs): Remove; now handled in the new
SC_AT_DIRECTIVE_ARG start condition.
(fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
functions.
(at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
at_directive_argv): New static globals.
(INITIAL): Use fail_for_invalid_at.
Don't parse `@output file_name\n' or `@basename(...@)'.  Instead,
recognize the start of a generalized `@directive(...@)' form and
start...
(SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
directive args (using the new obstack_for_string), to decode the
contained @ diagraphs, and to perform the directive.  It recognizes
@basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
@output(...@).
(SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
`@,'.
(scan_skel): Initialize obstack_for_string on the first call.
(skel_scanner_free): New function to free obstack_for_string.
* tests/input.at (Reject bad %code qualifiers): Update test output.

bd9d212b13 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
`bison ', use m4_index instead of m4_substr since chopping up a string
containing M4-special characters causes problems here.

Fix a couple of bugs related to special characters in user-specified
file names, and make it easier for skeletons to compute output file
names with the same file name prefix as Bison-computed output file
names.
* data/glr.cc, data/push.c, data/yacc.c: In @output, use
b4_parser_file_name and b4_spec_defines_file instead of
@output_parser_name@ and @output_header_name@, which are now redundant.
* data/glr.c, data/lalr1.cc: Likewise.  Also, in header #include's, use
b4_parser_file_name, b4_spec_defines_file, and the new
@basename(FILENAME@) instead of @output_parser_name@ and
@output_header_name@, which inappropriately escaped the file names as
C string literals.
* src/files.c (all_but_ext): Remove static qualifier.
(compute_output_file_names): Move `free (all_but_ext)' to...
(output_file_names_free): ... here since all_but_ext is needed later.
* src/files.h (all_but_ext): Extern.
* src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
exactly what MUSCLE_INSERT_STRING used to do.
(MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
characters are escaped properly.
* src/output.c (prepare): Define muscle file_name_all_but_ext as
all_but_ext.
For pkgdatadir muscle, maintain previous functionality by using
MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING.  The problem
is that b4_pkgdatadir is used inside m4_include in the skeletons, so
digraphs would never be expanded.  Hopefully no one has M4-special
characters in his Bison installation path.
* src/scan-skel.l: Don't parse @output_header_name@ and
@output_parser_name@ anymore since they're now redundant.
In @output, use decode_at_digraphs.
Parse a new @basename command that invokes last_component.
(decode_at_digraphs): New.
(BASE_QPUTS): Remove unused.
* tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
(Output file name): New tests.

(compute_output_file_names): Invoke output_file_name_check for files
not generated by the skeletons and remove existing checks.
(output_file_name_check): New function that warns about conflicting
output file names.
(output_file_names_free): Free file_names.
* src/files.h (output_file_name_check): Declare.
* src/scan-skel.l: Invoke output_file_name_check for files generated by
the skeletons.
* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.

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-skel.l (scan_skel): Likewise.

f9bfc42aa7 Clean up scanners a bit.
* src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
definitions so gcc won't warn when obstack_for_string is unused.
* src/scan-code.l: config.h and system.h are already #include'd by
scan-code-c.c, so get rid of them here.
* src/scan-gram.l: Likewise.
* src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
definitions rather than duplicating the rest of it.
* src/scan-gram-c.c, scan-skel-c.c: #include "system.h".

cb48f1919c Adjust to Autoconf 2.60 and today's gnulib.
* bootstrap (gnulib_modules): Add stdint.
Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
no longer copies it.
(intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
since stdint needs the former and wcwidth (which is now required
by mbswidth) needs the latter.
Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
work around a compatibility glitch between gettext 0.14.6 and
Autoconf 2.60.
* configure.ac (AC_PREREQ): Require Autoconf 2.60.
Do not check for uintptr_t, since new stdint module does the right
thing.
* lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
Add stdint.h, stdint_.h, wcwidth.h.
* m4/.cvsignore: Remove alloca.m4, onceonly.m4.
Add absolute-header.m4, double-slash-root.m4, longlong.m4,
stdint.m4, wchar_t.m4, wcwidth.m4.
* src/files.c: Include <dirname.h> and <stdio-safer.h> in the
usual order for ../lib/*.h files.
(file_name_split): Use last_component, not base_name, to adjust
to gnulib changes.
* src/parse-gram.h: Include <strverscmp.h> in the usual order
for ../lib/*.h files.
(YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
Define unconditionally, since we now assume the stdint module.
* src/scan-skel.l: Include <dirname.h>.
(BASE_QPUTS): Use last_component, not base_name.
* src/system.h: Include <unlocked-io.h> in the usual order
for ../lib/*.h files.  Include <stdint.h> unconditionally,
since we now use the stdint module.
(uintptr_t): Declare if UINTPTR_MAX is not defined, not
HAVE_UINTPTR_T, since we now use the stdint module.
(base_name): Remove decl, since files now include <dirname.h>
to get the decl.
2006-07-09 03:44:51 +00:00

06f01bc496 * src/assoc.c (assoc_to_string): Use a default: abort (); case
to pacify gcc -Wswitch-default.
* src/scan-gram.l (adjust_location): Use a default: break; case
to pacify gcc -Wswitch-default.
* src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
(skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
(skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
Move these decls to scan-skel.l, since they don't need to be
visible elsewhere.
* src/scan-skel.l: Accept the above decls.
