2017-05-06 Will Estes * po/ca.po, po/da.po, po/de.po, po/eo.po, po/es.po, po/fi.po, po/fr.po, po/ga.po, po/hr.po, po/ko.po, po/nl.po, po/pl.po, po/pt_BR.po, po/ro.po, po/ru.po, po/sr.po, po/sv.po, po/tr.po, po/vi.po, po/zh_CN.po, po/zh_TW.po: gettext: pulled latest translations; recompiled against current sources2017-05-06 Will Estes * NEWS: version 2.6.4 * NEWS: Record release date.2017-05-06 Will Estes * .prev-version: note previous version2017-05-06 Will Estes * NEWS: doc: update NEWS for upcoming release2017-05-04 viktor.shepel * doc/flex.texi: doc: Correct typo in C code sample in manual2017-05-04 Explorer09 * src/flex.skl: scanner: Mention %# comments are removed when building skel.c2017-05-02 Demi Obenour * src/flex.skl: Honor user definitions of yy_* macros The user may have defined the yy_* macros themselves. In that case, don't clobber them.2017-05-02 Demi Obenour * src/flex.skl, src/main.c: Don't leak macro definitions into header files This allowed unnamespaced definitions to leak into header files, breaking client code. Fixes #1422017-05-03 Demi Obenour * src/scan.l: scanner: Check for 0 bracecount when EOL ends quoted literal. This can happen in the case of // comments (which Flex doesn't handle specially).2017-05-03 Demi Obenour * src/scan.l: scanner: when bracelevel is negative, treat as zero. This really should never happen, but this at least fixes the breakage on Verilator.2017-04-02 Jeff Smith * tests/Makefile.am, tests/tableopts.am, tests/tableopts.sh: test: enable more silent building of tests. When running 'make V=0 check', some compile and link steps are made less verbose and some are not. This cleans up most steps that are not. These have no effect if V=0 is not specified.2017-05-03 Demi Obenour * src/Makefile.am, src/misc.c, src/mkskel.sh: build: Delete comments from skeleton file. Since the comments in flex.skl are, by hypothesis, not needed in skel.c, we remove them. THis reduces the size of the resulting executable somewhat.2017-05-03 Explorer09 * Makefile.am, configure.ac, lib/Makefile.am: build: do not generate lib/Makefile.in. Files in lib/ are picked up and built using makefile directives in src/Makefile.am. Remove the need to generate lib/Makefile.in and the stub lib/Makefile.am.2017-05-02 Will Estes * po/POTFILES.in: gettext: revert listing generated .c files2017-04-10 Jeff Smith * src/filter.c: FLEX_EXIT() is the preferred way to exit flex2017-04-11 Explorer09 * src/misc.c: Fix myesc() 'sptr' conditionals * Don't call isascii() here. It's deprecated in POSIX and not needed for myesc's case. * The check of the character class and range here should match what's defined as {ESCSEQ} in scan.l, so for [[:xdigit:]] we use isxdigit(); for [0-7] we check '0' <= c <= '7' (not isdigit(c) because isdigit is locale-dependant in standard's sense) * Add missing length limit for "\x" ( is at most 2 digits)2017-04-11 Explorer09 * src/flexdef.h, src/misc.c: Obsolete htoui() and otoui(); use strtoul(). No sense to keep these two function when libc's strtoul() can do the same job, but better.2017-04-12 Todd C. Miller * src/flex.skl: scanner: update yy_buf_size after yyrealloc()2017-05-02 Simon Sobisch * configure.ac: build: use lowest versions for gettext, automake.2017-05-02 Simon Sobisch * po/Makevars, po/Rules-getpo, po/update_linguas.sh: gettext: more recent makevars; new script to update po files. Previously, "make dist" and similar commands would cause the po files to be updated, which is incorrect. The more recent version now used should not do this. Replaced Rules-getpo by extra script to manually update and rebuild all po files.2017-05-02 Simon Sobisch * po/POTFILES.in: gettext: list generated files instead of flex, bison sources in POTFILES.in. Listing the flex and bison sources -- as the gettext manual suggests -- causes warnings. Listing the generated C files for the lexer and parser removes the warnings. Since both files contain line directives, any translator who needs to refer back to those files should be able to find the context in which strings are needed.2017-05-02 Simon Sobisch * autogen.sh: build: only touch ChangeLog if it does not exist2017-05-02 Simon Sobisch * configure.ac, doc/Makefile.am: build: list earliest useable versions for automake2017-05-02 Simon Sobisch * autogen.sh: build: check for how to call libtoolize. Previously, we would call libtoolize and if that failed, we would call glibtoolize since some platforms have the libtoolize program under that name. Instead, we check to see if the environment variable LIBTOOLIZE is set and use that if so. Otherwise, we try to find a program "libtoolize" on the path and failing that glibtoolize. We alert the user if no suitable program can be found.2017-01-06 Alastair Hughes * configure.ac, m4/ax_prog_cc_for_build.m4, src/Makefile.am: build: support cross compiling. Check for cross compiling. If cross compiling, build stage1flex using a custom link command. We also override LDADD since that adds the replacement implementations that are cross compiled, and instead always use the replacement library implementations. We don't use BUILD_OBJEXT and BUILD_EXEEXT since it seems that automake does not support these. Fixes #78.2017-02-17 Explorer09 * configure.ac, src/flexdef.h: build: Include ; add strcasecmp() check to configure. strings.h (not string.h) is the standard-defined include header for strcasecmp(). Include for portability (even though glibc exposes strcasecmp() declaration also in by default).2017-02-17 Explorer09 * configure.ac, src/flexdef.h: build: Let configure error if missing required functions, headers.. `configure` will now error if a required header or function is not found on the system. Also add comments on optional functions checks. Add sys/stats.h and sys/wait.h to list of required headers in configure. This fixes issue #180.2017-02-12 Explorer09 * src/dfa.c, src/flexdef.h: scanner: compute powers of two faster. Replace the naive "for" loop in determining power of two with a clever bitwise solution. This code is around the Internet already and is in Public Domain.2017-02-07 Explorer09 * configure.ac, tests/Makefile.am, tests/pthread.l: test: skip pthread test when needed files missing. "Unlisting" the pthread test when libpthread is not available is never a good idea. Should let it compile into a stub program that returns the "skip" status. configure.ac and tests/Makefile.am are edited so that pthread test can be built anyway, but only works (not as the stub) when both pthread.h and libpthread are detected on the system. Also fix a small typo in tests/pthread.l comments.2017-02-16 Will Estes * src/Makefile.am: build: mv scan.c when building dist. Revert change to copy scan.c when building the distribution archive. Move it instead. This satisfies automake's notions of what should be clean and ensures that the distribution archive contains a just-built copy of scan.c. Fixes #1862017-02-06 Will Estes * src/Makefile.am: build: don't assume distdir/scan.c is writeable2017-01-02 Explorer09 * src/Makefile.am: build: Add dist-hook to force remake scan.c. This will ensure the flex scanner included in release tarball being generated by exactly the flex version to be released. Here's one catch after this change: You may not run "make dist" or "make distdir" if you configure the flex source to be cross-compiled.2017-01-02 Explorer09 * src/Makefile.am: build: respect '--localedir' from configure. Makefile shouldn't overwrite the 'localedir' variable, because that's what '--localedir' option in 'configure' is for.2017-01-02 Explorer09 * src/Makefile.am: build: Remove "-I$(top_srcdir)/intl" from CPPFLAGS. Revert commit e02c3d27eeb6b53ec82532ab080c23ce26813fd4 ("include the intl/ subdirectory when searching for include files") Flex doesn't come with libintl source code, so inclusion of $(top_srcdir)/intl subdirectory during compiling is unnecessary. This flag seems to be left after "remove intl from dist" (commit 8f45da06adbd7dbcdfdbdd5c20ff4c47fc504f35) without someone cleaning this up. Users who need to build with gettext functionality from libintl would use the '--with-libintl-prefix' configure option.2017-02-03 Explorer09 * src/regex.c: scanner: fix regcomp's error reporting, double malloc. Fix unneeded double malloc - let regerror(). Write its message after our "regcomp for (regex) failed: " string. Also, errbuf cannot be free()'d because of flexfatal containing a longjmp.2017-01-03 Explorer09 * tests/Makefile.am, tests/no_bison_stub.c: test: Skip bison tests if bison is not available2017-01-03 Explorer09 * configure.ac: build: remove repeated bison detection from configure. AC_PROG_YACC already detects the bison program. We can just use it, and make notice if [ $YACC != 'bison -y' ] Remove unused AC_SUBST([BISON], ...). Add AM_CONDITIONAL([HAVE_BISON], ...) so that we can skip bison tests in testsuite when bison is absent. We don't make any attempt to detect other yacc implementations since flex is developed with bison. While it would be possible, the need isn't there right now. It would be possible to add a --with-parser option that defaulted to bison if such a need cropped up.2017-01-01 Explorer09 * src/Makefile.am: build: fix Makefile parse.h dependency clauses. The current clauses stating "main.c: parse.h" and "yylex.c: parse.h" do not work as expected. Make did not try to build parse.h upon building flex-main.o as it would think main.c exist already and ignore the clause. Fix this by explicitly stating that the .o files depend on parse.h instead. This dependency bug only happens if user builds flex from a checked-out repository.2017-01-03 Explorer09 * tests/Makefile.am: test: Remake *_scanner.c if *_scanner.h is missing. If a ${foo}_scanner.c exists but the respective ${foo}_scanner.h is missing, then 'make' can halt. Fix this by deleting the ${foo}_scanner.c file and then remake it. This rule is the same as the automake-generated rule for .c files that require LEX or YACC (except automake will use ylwrap).2016-12-31 Explorer09 * tests/Makefile.am: test: remove BUILT_SOURCES; add missing dependencies. Without BUILT_SOURCES in Makefile, no test sources in tests/ will be built when using the default "make all" target. This is desireable for people who are just building flex but who do not want to run, and therefore, build any part of the test suite. Also fix missing sources dependencies: bison_nr_scanner.$(OBJEXT): bison_nr_parser.h bison_yylloc_scanner.$(OBJEXT): bison_yylloc_parser.h bison_yylval_scanner.$(OBJEXT): bison_yylval_parser.h2017-01-19 Explorer09 * configure.ac, lib/reallocarray.c, src/flexint.h, src/misc.c: build: detect overflow for [re]allocate_array. Use reallocarray() when we have it (i.e. in OpenBSD system). When we don't, use equivalent overflow detection for our allocate_array and reallocate_array functions. Remove lib/reallocarray.c from our LIBOBJS as we no longer need it. Provide a fallback SIZE_MAX macro definition in flexint.h (not preprocessor friendly, but enough for our reallocate_array use case).2017-01-23 Will Estes * NEWS, configure.ac: doc: v2.6.42017-01-23 Thomas Klausner * src/Makefile.am: build: more BSD make and vpath build fixes. BSD make doesn't like $< with more than one source specified. Additionally, make sure to specify srcdir when referring to source files since vpath builds depend on this.2017-01-22 Thomas Klausner * src/Makefile.am: build: Fix skel.c generation with BSD make2017-01-22 Christos Zoulas * src/flex.skl: Add more defines in the non-reentrant part. Fix the reentrant part; don't "#define yyfoo yyfoo" because it breaks code that does #ifndef yywrap ..2017-01-22 Christos Zoulas * src/flexdef.h: scanner: Add yyparse prototype2017-01-22 Thomas Klausner * src/flex.skl: scanner: move comment for consistency2017-01-22 Christos Zoulas * src/misc.c: scanner: Use array instead of pointer2017-01-22 Christos Zoulas * src/main.c: scanner: manage path to m4 better. Avoid alloca() for SSP; it is better anyway; since we don't need to strdup the path.2017-01-22 Christos Zoulas * src/gen.c: scanner: Avoid creating unused label2017-01-22 Christos Zoulas * src/buf.c: Cast argument to avoid arithmetic on void *.2017-01-22 Christos Zoulas * src/scan.l: scanner: Use strncpy2017-01-22 Christos Zoulas * src/main.c: scanner: Use prefix when defining yywrap to avoid redefinition. Fixes regression introduced in v2.6.3.2017-01-22 Christos Zoulas * src/flexdef.h, src/misc.c: scanner: Include stdarg.h for va_list2017-01-22 Christos Zoulas * src/flexdef.h, src/main.c, src/parse.y: scanner: Rename warn to lwarn. This avoids a naming conflict in NetBSD's libc.2017-01-01 Explorer09 * tests/README: test: document automake convention for skipped exit status.2017-01-03 Explorer09 * tests/Makefile.am: test: let testwrapper scripts be run by ${SHELL}. This allows user to use a different shell if /bin/sh has problems. The use of $SHELL (variable) to run scripts is already an Automake convention. All shell scripts in build-aux are run by $SHELL.2017-01-02 Explorer09 * tests/options.cn, tests/tableopts.sh, tests/testwrapper-direct.sh, tests/testwrapper.sh: test: Remove test scripts bashisms. They now all work under a POSIX compliant sh. Specifically, 'dash' can now be used for running "make check" tests. Note that none of these scripts has ever been using a pipe, so `set -o pipefail` is unnecessary and removed.2017-01-02 Explorer09 * tests/testwrapper.sh: test: exit on '-1' test non-zero status. If a '-1' test program returns a non-zero status, don't go further and compare it's (numeric) output values. This allows a '-1' test to indicate a "skip" status or an otherwise error. (Currently no such '-1' test would skip like this, though.) Shell syntax note: `set -e` will not exit with the syntax like this `test $(false) = $(false);`. The exit statuses of `false` in the example will be ignored instead. But putting the output in a variable, such as `VAR=$(false)`, DOES exit.2017-01-02 Explorer09 * Makefile.am, src/Makefile.am: build: Fix 'make indent' target This 'make indent' target has not been working since the directories reorganization in flex 2.6.0. Now make it work again. Note that the current indent profile breaks many styles of existing code. The indent target should not be used until the .indent.pro options are reviewed for desireability.2017-01-01 Explorer09 * configure.ac: build: Simplify indent program detection2017-01-12 Tobias Klauser * src/filter.c: filter: Don't emit #line if %option noline set One place emitting a #line directive to the generated header was missed in commit 647a92b9f4 when resolving #55. Fix it to respect gen_line_dirs as well.2017-01-12 Will Estes * po/ca.po, po/da.po, po/de.po, po/eo.po, po/es.po, po/fi.po, po/fr.po, po/ga.po, po/hr.po, po/ko.po, po/nl.po, po/pl.po, po/pt_BR.po, po/ro.po, po/ru.po, po/sr.po, po/sv.po, po/tr.po, po/vi.po, po/zh_CN.po, po/zh_TW.po: translation: refresh po files from translation project2017-01-10 Harald van Dijk * src/flex.skl: c++: Fix yyrestart(NULL) SEGV. Binding a reference to a dereferenced null pointer is invalid and compilers optimise away the &file == 0 check. We need a real stream. yyin is available already, and yyrestart(NULL) is only supported when yyin will not be used, so there is no harm in just passing in that. Since we now always have a valid stream, we can skip the null check too. Fixes #98.2017-01-09 luistung * src/scan.l: scanner: join symbol list. Removed a newline that caused a problem building the scanner in some circumstances. Specifically: 'bad character' error when executing /bin/sh ../build-aux/ylwrap scan.l lex.yy.c scan.c -- flex2017-01-11 Will Estes * src/flex.skl: scanner: remove void cast before fprintf List of files: /netbsd-src/external/bsd/flex/dist/ChangeLog

Mon, 02 Jan 2017 16:26:30 +0000

2016-12-30 Will Estes * NEWS: doc: update NEWS for 2.6.3 release2016-11-26 Explorer09 * configure.ac, src/Makefile.am: build: New configure option '--disable-bootstrap'. If configure is run with '--disable-bootstrap', then stage1flex won't be built and stage1scan.c will be generated by sed'ing scan.c. This option is intended to workaround bootstrap bugs rather than to fix the bootstrapping issues which are proving subtler and harder to fix than anyone would like.2016-11-26 Explorer09 * src/Makefile.am: build: "make clean" deletes stage1scan.c, stage1flex2016-11-26 Explorer09 * configure.ac, src/Makefile.am: build: allow building libfl even with --disable-libfl. For various reasons, we may wish to build libfl explicitly even when configure has been run with the --disable-libfl option. This is possible, now, via 'make -C src libfl.la'.2016-12-19 Alexis La Goutte * src/flex.skl: scanner: remove trailing whitespace in skeleton2016-12-01 Demi Obenour * src/buf.c, src/main.c, src/parse.y: scanner: Disallow, overquote '[' and ']' in prefix2016-12-29 Samuel Thibault * src/main.c: scanner: allocate correct buffer size for m4 path. Flex did not check the length of the m4 path which could lead to a buffer overflow in some cases. Additionally, not all platforms believe in PATH_MAX, so stop relying on it. Fixes #1382016-11-24 Will Estes * NEWS: doc: note no more libcompat in NEWS2016-11-24 Will Estes * lib/Makefile.am: build: explain empty lib/Makefile.am2016-11-20 Explorer09 * configure.ac: build: warn about cross compiling with *alloc2016-11-19 Explorer09 * configure.ac, lib/Makefile.am, lib/lib.c, src/Makefile.am: build: Link $(LIBOBJS) from src/ dir, remove libcompat.la. The libcompat.la library was small and less friendly to bootstrapping and cross compilation. Now, we will simply link individual object files as needed, which is simpler.2016-11-16 Explorer09 * src/Makefile.am: build: Let stage1flex respect LFLAGS2016-11-14 Will Estes * NEWS: doc: describe --disable-libfl in NEWS2016-10-31 Explorer09 * configure.ac, src/Makefile.am: build: Add --disable-libfl configure option. Disabling libfl is useful when building flex for a cross-toolchain. Fixes: GH-992016-11-09 Demi Obenour * src/flex.skl, tests/array_r.l: fix backwards incompatible changes in 2.6.2. This patch addscompatibility `#defines` for all macros affected by `%prefix`. Fixes #113.2016-11-08 Will Estes * tests/.gitignore: git: ignore quote_in_comment artifacts2016-11-08 Demi Obenour * src/scan.l, tests/Makefile.am, tests/quote_in_comment.l, tests/quote_in_comment.txt: Fixes a major bug in Flex's own lexing of literals. My changes caused Flex to mishandle string and character literals in line comments. This commit fixes them. Fixes #113.2016-11-06 Thomas Klausner * configure.ac: Fix unportable test(1) operator. "==" is only supported by bash, "=" is the standard comparison operator.2016-11-02 Demi Obenour * tests/quotes.l: Add more escaping tests2016-11-01 Demi Obenour * src/scan.l: Fix another escaping bug in non-indented verbatim section 2 code. I also did some reformatting.2016-10-28 Alastair Hughes * configure.ac: build: fix false negatives for help2man and texi2dvi HELP2MAN and TEXI2DVI (or the corresponding ac_prog variables) will never be zero length as they fall back to the missing script; check for the fall back and warn on that instead of always warning.2016-10-28 Explorer09 * doc/Makefile.am: doc: Don't delete flex.1 during "make distclean". flex.1 is pre-generated in release tarball. If we delete it, the next "configure and make" on the source directory will then require help2man unnecessarily.2016-10-27 Alastair Hughes * NEWS, doc/Makefile.am: Only regenerate the man page when required. Make the flex binary an order-only prerequisite, and add back the prerequisites from before 7cfb440. This prevents rebuilding the man page whenever the flex binary is rebuilt, which causes problems if help2man is not installed and will never work when cross compiling. Fixes #108.2016-10-26 Will Estes * NEWS, src/Makefile.am: build: no longer build PIC version of libfl. The PIC version of libfl was not being built correctly. From the lack of bug reports around this problem, we conclude that the PIC version of libfl is not used and so we drop it from the build build targets for flex.2016-10-25 Explorer09 * README.md: doc: README.md formatting fixes * Wrap everything in the raw document in 72 char per line limit. * Proper casing for terms "Git" and "GitHub" (don't try to look lazy). * Add unordered list marks when needed. * Say `configure && make && make install` and quoted for fixed-width font. Signed-off-by: Kang-Che Sung 2016-10-25 Will Estes * NEWS, configure.ac: build: version 2.6.3 begins2016-10-24 Will Estes * NEWS: doc: mark 2.6.2 release date2016-10-24 Will Estes * .gitignore, NEWS, configure.ac: build: switch xz to lzip2016-10-20 Demi Obenour * src/scan.l, tests/quotes.l: Fix M4 quotation in section 2 prologue and refactor duplicated code2016-10-21 Alex Kennedy * doc/flex.texi: Update flex.texi: Removed repedative wording "Flex used to" was written twice at the beginning of Chapter 9, paragraph 2.2016-09-27 Demi Obenour * src/dfa.c, src/gen.c, src/main.c, src/nfa.c, src/parse.y, src/scan.l, tests/bison_yylval_scanner.l, tests/include_by_push.direct.l: Improved M4 quotation This fixes M4 quotation of certain strings beginning with `yy` (in section 3 of the input file only) and character literals. The new quotation method is also less brittle and faster. Tests that relied on the old behavior were fixed. Also, `yyconst` is no longer defined; use `const` (which it unconditionally was defined to) instead.2016-10-19 Will Estes * Makefile.am, configure.ac: build: for automake, flex is foreign2016-10-19 Will Estes * README, README.md: doc: mv README to README.md2016-10-19 Will Estes * README: doc: touch up README2016-10-19 Will Estes * README: doc: README no longer mentions sourceforge2016-10-06 Will Estes * NEWS: doc: update NEWS with more post-2.6.1 additions2016-09-27 Demi Obenour * src/filter.c, src/flexdef.h, src/main.c, src/misc.c, src/options.c, src/options.h, src/scan.l, src/yylex.c, tests/Makefile.am, tests/alloc_extra.l, tests/array_r.l, tests/basic_r.l, tests/c_cxx_nr.lll, tests/c_cxx_r.lll, tests/debug_r.l, tests/include_by_reentrant.direct.l, tests/lineno_r.l, tests/mem_nr.l, tests/mem_r.l, tests/posix.l, tests/posixly_correct.l, tests/pthread.l, tests/quotes.l, tests/reject.l4, tests/rescan_nr.direct.l, tests/rescan_r.direct.l, tests/string_nr.l, tests/string_r.l: Fix M4 quoting of section 3. This fixes M4 quoting of section 3 of the input file, including escape sequences and character constants. Tests were added to verify the behavior in section 3 with respect to quoting. Both escaping of quotes and quoting of potential macro-start characters are tested. Existing tests were also fixed to account for the new -- and now correct -- behavior. Many tests relied on the old behavior of expanding M4 macros in section 3. They needed to be updated for the new behavior.2016-10-03 Mightyjo * src/flex.skl, tests/.gitignore, tests/Makefile.am, tests/cxx_restart.ll, tests/cxx_restart.txt: Fix yyrestart(NULL) SEGV.2016-09-05 Demi Obenour * src/scan.l: scanner: M4 quoting fixes2016-09-05 Demi Obenour * src/Makefile.am: Support `make indent` for out of source builds2016-09-24 Demi Obenour * src/Makefile.am, src/mkskel.sh: Simplify some shell code2016-09-23 Demi Obenour * doc/flex.texi, src/flex.skl, src/flexdef.h, src/main.c, src/options.c, src/options.h, src/scan.l, tests/.gitignore, tests/Makefile.am, tests/noansi_nr.l, tests/noansi_nr.txt, tests/noansi_r.l, tests/noansi_r.txt: no longer generate K&R C scanners2016-09-04 Demi Obenour * src/scan.l: Fix escaping of `[[` and `]]` in strings Previously, `[[` and `]]` were not escaped in strings, which led to bad interactions with m4. Also, don't break strings on newline, as GCC et al support whitespace between a backslash and the subsequent newline.2016-06-20 Translation Project * NEWS, po/sv.po: new sv translation2016-05-23 Demetri Obenour * src/misc.c: Delete action_m4_define from misc.c This function was not used and always triggered a fatal error when run.2016-05-20 Will Estes * tests/Makefile.am, tests/testwrapper-direct.sh: test: run direct tests from srcdir2016-01-11 Egor Pugin * tests/include_by_buffer.direct.l, tests/include_by_push.direct.l, tests/include_by_reentrant.direct.l: Exited with error code on some conditions in include tests2016-05-20 Will Estes * tests/testwrapper.sh: test: drop .exe when making input file names2016-05-20 Will Estes * tests/Makefile.am: test: removed dependencies for include tests2016-04-28 Tobias Klauser * src/scanflags.c: Avoid realloc on every call of sf_push() Currently, every call to sf_push() realloc()'s _sf_stack, even if the maximum size _sf_max wasn't changed.

The variable yy_n_chars had been of type yy_size_t which is incorrect given its use in read(). While it might be adviseable to look at defining a yy_ssize_t, there might be some issues doing this and so, for now, at least, we'll punt back to int.2016-02-24 Will Estes * src/buf.c: Fixed size of bufferallocation, resolved gh#54. The value of n_alloc was a count, not a size. Multiplying the value by the element size was incorrect. That multiplication was already being done and having it done twice was incorrect.2016-02-23 Tobias Klauser * src/scan.l: Allow '%option noline' in flex input file, resolves gh#56.

Signed-off-by: Tobias Klauser 2016-02-16 Tobias Klauser * lib/lib.c, src/gen.c, src/misc.c, src/scan.l: Converted K&R style function definitions to ANSI C style Consistently make use of the ANSI C function definition style instead of the K&R style.2016-01-29 Tobias Klauser * src/flex.skl: Used NULL constant instead of plain integer for NULL pointer. The sparse static checker warns about using plain integer 0 as NULL pointers in the generated lexer code. Fix this by using NULL consistently for pointers.2016-01-29 Tobias Klauser * src/flex.skl: Marked declaration and definition of yy_fatal_error as noreturn. Only the declaration of yy_fatal_error is marked with __attribute__((__noreturn__)) in case GCC >= 3 is used, but not the definition. This leads to the sparse static checker to complain about function declaration mismatch. Fix it by defining a macro yynoreturn and using it for both the declaration and the definition of yy_fatal_error.2016-01-27 Tobias Klauser * src/flex.skl: Fixed declaration mismatch in yy_fatal_error. The prototype declares yy_fatal_error parameter as "const char msg[]" while the definition uses "const char* msg" (introduced by commit e9d5fc713f61b) which causes the sparse static checkers to produce an error. Fix this by adjusting the definition to use "const char* msg" as well. Also change the C++ version accordingly so it matches the declaration in FlexLexer.hpp.2016-01-23 Will Estes * CODE_OF_CONDUCT.md: flex is for flex #NCoC2016-01-18 Will Estes * doc/flex.texi: Referred to github for issue tracking, no longer sf2016-01-10 Egor Pugin * tests/reject.l4, tests/tableopts.l4: Opened files in binary mode explicitly2016-01-08 OBATA Akio * src/Makefile.am: Linked flex binary against libintl, not libfl.

Given the following program: \#include \#include /* extracts basename from path, optionally stripping the extension "\.*" * (same concept as /bin/sh `basename`, but different handling of extension). */ static char *basename2 (char *path) { char *b; for (b = path; *path; path++) if (*path == '/') b = path + 1; return b; } static void basename_compare(char *path) { printf("basename: %s\n", basename(path)); printf("basename2: %s\n\n", basename2(path)); } int main (int argc, char *argv[]) { // From http://pubs.opengroup.org/onlinepubs/9699919799/ // ``Sample Input and Output Strings'' basename_compare("/usr/lib"); basename_compare("/usr/"); basename_compare("/"); basename_compare("///"); basename_compare("//usr//lib//"); return 0; } ... and the program's output: basename: lib basename2: lib basename: usr basename2: basename: / basename2: basename: / basename2: basename: lib basename2: ... we can see that basename2() behaves the same as basename(3) in the average use case, but messes up pretty severely in others. Besides that, basename(3) is mandated by POSIX so should be present on modern Unix-like systems, so we shouldn't define it ourselves. Some notes: - it doesn't appear to be mentioned in POSIX, but OpenBSD's basename(3) returns NULL if the returned path componenet is > PATH_MAX, so add a check for that - basename(3) shouldn't return an empty string, so remove the program_name[0] != '\0' check2015-12-25 Michael Reed * src/main.c: Simplify basename2(). It's only call site does not activate the `strip_ext` code path, so the function can be simplified a lot.

Lines starting2015-12-12 Mike Frysinger * tests/Makefile.am, tests/testwrapper.sh: tests: fixed paths to input files. The current test wrapper works only when the inputs are specified using relative paths. If they're specified with absolute paths, the driver fails to detect the inputs because it always prepends the input dir name which itself is a relative path: $ cd tests $ ./testwrapper.sh -d . -i $PWD/reject.txt -t ./reject_ver.table This normally doesn't show up because people run `./configure` or, for out of tree builds, `../configure`. But if you happen to run configure with an absolute path, then automake tends to generate absolute paths as well leading to test failures. Fix all of this by dropping the implicit input directory prepending. - INPUT_NAME is often a list of files, not just a single one - the input directory is used to find the testname tables which are usually generated, so it's impossible to use files from both source and build directories - most of the time, the full/correct path is already specified2015-12-12 Mike Frysinger * configure.ac: configure: fixed realloc test. The [] characters are used for quoting in m4, so the attempt to use them in place of `test` fails yielding the warning at build time: .../flex/configure: line 20222: no: command not found2015-12-12 Michael McConville * src/flexdef.h: Started removal of PROTO macro. The PROTO macro is no longer needed. Additionally, its usage is inconsistent, so we began removing it.2015-12-12 Michael Reed * Makefile.am, src/main.c: Removed SHORT_FILE_NAMES preprocessor symbol. As a relic of MS-DOS, we don't need this. It's never defined; see 13b5b214f53d1c3354a7ab910bd160c126df1331. Removed additional MSDOS ifdef.2015-12-11 Michael McConville * configure.ac, lib/reallocarray.c, src/flexdef.h: Added new function reallocarray. This is taken from OpenSSH Portable, which in turn takes it from OpenBSD. reallocarray wraps the stdlib's realloc function. It takes two size arguments and checks for overflow, like calloc, but doesn't zero the memory. Therefore, it allows us to do overflow-safe array reallocations and overflow-safe unzeroed array allocations, which the stdlib allocation functions don't. We have a bunch of specific array allocation macros, none of which check for overflow. reallocarray should be able to replace them.2015-12-11 Michael McConville * src/flexdef.h: Removed MS-DOS, VMS macros. Given the age of the MS-DOS and VMS platforms, it's likely that no one is building flex on them any more. Additionally, the preferred approach is to test for particular platform features rather than to test for particular platforms.2015-12-12 Will Estes * src/flexdef.h, src/main.c: Made search for m4 more explicit.2015-12-12 Will Estes * src/flex.skl: Returned 0 from yywrap() instead of EOF2015-12-11 Will Estes * src/libmain.c: Changed end of main() in libmain to exit(0)2015-12-11 Will Estes * NEWS, configure.ac: Mentioned v2.6.1; documented some changes since v2.6.02015-12-11 Will Estes * README: Updated build documentation; finished sf#155.

Since this only added unclarity, and the flex_alloc() function is likely a legacy of olden times, remove it in favor of calls to malloc() directly. Style elements cleaned up: * superfluous spacing around parentheses * non-constant initialization in variable declarations * needless casts * almost all uses of assignments as subexpressions2015-12-07 Michael McConville * src/dfa.c, src/flexdef.h, src/gen.c, src/main.c, src/scan.l, src/scanopt.c, tests/bison_nr_scanner.l, tests/bison_yylloc_scanner.l, tests/bison_yylval_scanner.l, tests/mem_nr.l, tests/mem_r.l, tests/pthread.l, tests/string_nr.l, tests/string_r.l, tests/yyextra.l, to.do/unicode/scan.l: Remove allocation casts2015-12-07 Will Estes * src/.gitignore, src/Makefile.am: Built flex with itself. Changes in scan.l need to be built into flex with the same version of flex in some cases. Since this build requirement is minimal, we simply bootstrap flex unconditionally. We intentionally exclude from version control the bootstrap artifacts as the extra copy of the lexer, the intermediate scanner and the bootstrap executable are not of interest.2015-12-05 Michael McConville * src/buf.c, src/dfa.c, src/main.c, src/nfa.c, src/parse.y, src/scan.l, src/scanopt.c, src/sym.c, to.do/unicode/main.c, to.do/unicode/scan.l: Use NULL rather than (type *) 0.2015-12-05 Michael McConville * src/flexdef.h, src/misc.c, src/sym.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c: Replace copy_unsigned_string() with xstrdup(). Like copy_string(), copy_unsigned_string() is just a clone of the stlib's strdup(). We only use it twice. I'm pretty confident that char signedness is irrelevant in this case.2015-12-04 Akim Demaille * src/FlexLexer.h: Cleaned up white space.2015-12-04 Akim Demaille * src/FlexLexer.h: Removed struct keyword before yy_buffer_state2015-12-04 Akim Demaille * examples/testxxLexer.l, src/FlexLexer.h, src/flex.skl, src/main.c: Replaced FLEX_STD macro with std::. The std:: construct exists as of C++98, so we can simply assume it is supported.2015-12-04 Akim Demaille * src/Makefile.am: Generated skel.c explicitly in srcdir. Rewrote the target for skel.c to explicitly mention the srcdir. This should help when building flex from a directory outside the flex tree. Spread the rule out over several lines to enhance readability.2015-12-04 Akim Demaille * autogen.sh: Called glibtoolize if libtoolize run fails. On Mac OS X, libtoolize is known as glibtoolize. In cases where libtoolize is not present, then calling glibtoolize when bootstrapping the build system gives more folks a shot at getting flex built from the ground up.2015-12-02 Mightyjo * configure.ac: Checked for (g)texi2dvi. Better bison, help2man checks. Added test for presence of (g)texi2dvi program. Gave notice if texi2dvi is unavailable and set TEXI2DVI=: to avoid giving users headaches. Enhanced tests for bison and help2man with notices when the programs aren't found. Set their program variables to use the missing script in build-aux since it's compatible with them.2015-12-02 Michael McConville * src/flexdef.h, src/misc.c, src/parse.y, src/scan.l, src/sym.c, src/tables.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c, to.do/unicode/scan.l: Made string copying more standard. copy_string() was a clone of the stdlib's strdup(). For safety, simplicity, and speed, we should use that instead. We introduce xstrdup() which wraps strdup() in a failure upon memory allocation errors.2015-11-30 Serguey Parkhomovsky * src/scan.l: Error on unbalanced parentheses in rules section.2015-11-29 Will Estes * src/Makefile.am: Cleaned up BUILT_SOURCES list. Removed reference to skel.c as a built source since other make rules cover this case.2015-11-29 Will Estes * src/Makefile.am: Sorted file names in flex_SOURCES2015-11-27 Mightyjo * src/ecs.c, src/flexdef.h, src/main.c, src/misc.c, src/scan.l, src/scanopt.c, src/sym.c, src/tblcmp.c: Replaced CHAR macro with unsigned char type. Thanks to Michael McConville for pointing out that the old Char macro causes problems with static analysis. The macro has been removed and replaced with 'unsigned char' throughout the flex sources. The macro is not needed at best and was confusing at worst. It was not used in any of the example files nor was it mentioned in the manual at all.2015-11-21 Will Estes * configure.ac: updated syntax of AC_INIT call as per autoupdate2015-11-21 Will Estes * tests/Makefile.am: removed extra call to a _CPPFLAGS variable2015-05-14 Stefan Reinauer * src/buf.c, src/ccl.c, src/dfa.c, src/ecs.c, src/gen.c, src/main.c, src/misc.c, src/nfa.c, src/parse.y, src/scan.l, src/scanopt.c, src/sym.c, src/tblcmp.c: Switch function definitions from mixed K&R to consistent ANSI C. flex was using K&R function definitions for some functions and ANSI C style in others, sometimes even in the same file. Change the code to consistently use ANSI C. Signed-off-by: Stefan Reinauer 2015-11-16 Mightyjo * tests/Makefile.am: Used in-tree header file for c++ tests.
