        maint: remove all trailing white space
        First, run this command:
          git grep -l '  $'|xargs perl -pi -e 's/[ \t]+$//'
        Then some minor fix-up to make the two newly-failing tests
        pass once again:
        * testsuite/mac-mf.sed: Append this, s/ $//,
        to eliminate trailing spaces in the actual output.
        * testsuite/y-newline.good: Manually remove a trailing
        space between two concatenated prompts.

2014-09-06  Jim Meyering  <[email protected]>

        fixup: add the properly-named new test files
        * testsuite/Makefile.am (EXTRA_DIST): Add y-zero.*,
        not y-NUL.* here.

        maint: correct failing "version" test
        * configure.ac (COPYRIGHT_YEAR): Update to 2014, so
        the "version" test passes once again.
        * doc/sed.1: Also commit this auto-generated-yet-VC'd file.

2014-09-04  Jim Meyering  <[email protected]>

        fix "y" to work with NUL in the RHS
        * sed/execute.c (do_list) [case 'y']: Handle NUL bytes
        in the RHS of a y/LHS/RHS/ transliteration.
        * testsuite/y-zero.good: New test-related files.
        * testsuite/y-zero.inp:
        * testsuite/y-zero.sed:
        * testsuite/Makefile.am (SEDTESTS): Add y-zero here.
        * testsuite/Makefile.tests: And here.
        * NEWS (Bug fixes): Describe it.
        The bug was reported by [email protected],
        with the execute.c change mostly by Paolo Bonzini.

2013-10-16  David A. Wheeler <[email protected]>

        * doc/sed-in.texi: Document "-E" option to use EREs.  GNU sed already
          supported "-E" as an undocumented synonym for "-r", but "-E" is now
          in POSIX.  See: http://austingroupbugs.net/view.php?id=528.

        * doc/sed.texi: Likewise.
        * doc/sed.x: Likewise.
        * sed/sed.c: Likewise.

        * sed/utils.c: Do not include pathmax.h anymore.
        * bootstrap.conf (gnulib_modules): Do not use the gnulib module
        pathmax.

2013-09-30  Jose E. Marchesi  <[email protected]>

2012-12-29  Stefano Lattarini  <[email protected]>  (tiny change)

        maint: enable Automake parallel testsuite harness
        It is better than the older test driver.  It is also the
        default now, starting from Automake 1.13; so having it
        enabled unconditionally will allow GNU sed to be seamlessly
        bootstrapped by Automake 1.13.
        * configure.ac (AM_INIT_AUTOMAKE): Add 'parallel-tests' option.
        Also require Automake 1.11.1, since that is the minimal version
        to have a sane 'parallel-tests' support.
        (AC_PREREQ): Bump requirement to 2.62, since that is the
        minimal version required by Automake 1.11.1.
        * testsuite/Makefile.am (TESTS_ENVIRONMENT): Remove the
        invocation for the test runner "$(srcdir)/runtest"; it's
        correct place is ...
        (LOG_COMPILER): ... here.

2012-12-29  Stefano Lattarini  <[email protected]>  (tiny change)

        label.  For TEXT_REPLACEMENT add a backslash to the output if

        Dennis Bartlett.

2011-07-11  Jim Meyering  <[email protected]>

        avoid silent data loss when an input line is 2^31 bytes or longer
        If one line in a file has length (including newline) of 2^31, then
        applying sed -i to that file truncates it to size 0.  I first
        noticed it like this: Create a file with line of length 2^31-1
          $ perl -le 'print "v"x(2**31-1)' > k
        Then prepend a byte to that line:
          $ sed -i 's/^/v/' k
        Surprise!  The file is empty.
        * sed/utils.c (ck_getline): Declare "result" to be of type ssize_t,

            Paolo Bonzini  <[email protected]>

        Change the way we treat lines which are not terminated by a newline.
        Such lines are printed without the terminating newline (as before)
        but as soon as more text is sent to the same output stream, the
        missing newline is printed, so that the two lines don't concatenate.

        * sed/execute.c (output_file): Is now struct output; users adjusted
        to access the fp field, call output_missing_newline before, and
        call flush_output afterwards.
        (read_file_line): Set line.chomped FALSE each time we encounter a
        line without the newline terminator, no matter whether this is the
        last input file or not, and no matter whether we are in
        POSIXLY_CORRECT mode or not.
        (output_missing_newline): New function which prints the suppressed
        newline, if necessary.
        (flush_output): New function for a common pattern.
        (output_line): Use struct output, set its flag accordingly.
        (dump_append_queue): Use `ck_fwrite' instead of output_line.
        (do_list): Flush the output stream at the end.
        (closedown): The code ``if(separate_files) rewind_read_files();''
        (read_pattern_space): ... has been moved here.
        (process_files): Don't do the default `p' at the end, ...
        (execute_program): ... as this function is now responsible for it;
        add the code to the end of the function and to the command `q';
        the commands `d', `D' and `Q' thus no longer have to forge an empty
        line.
        (execute_program): Commands `c' and `i' no longer call the
        function output_line with chomped==FALSE; instead, they chomp
        the text and call the function with chomped==TRUE.
        (execute_program): Command `e' no longer uses output_line; it
        calls ck_fwrite directly.  Commands `e', `L' and `=' flush
        the output stream at the end.
        * sed/compile.c (special_files): Use `struct output' instead of the
        file name.
        (get_openfile): ... special files are no longer copied to file_read
        or file_write.
        (fp_list): Move to sed.h (users adjusted) and rename as...
        * sed/sed.h (struct output): ...this.  New flag missing_newline
        associated to the output stream.
        (struct sed_cmd, struct subst): Use `struct output *' instead of mere
        `FILE *'; adjust compile.c and execute.c.
        * testsuite/noeolw.sed, testsuite/noeolw.good, testsuite/noeolw.1good,
        testsuite/noeolw.2good: New tests

        preserve two occurrences of the `e' and `p' options.
        * sed/execute.c (do_subst) [HAVE_POPEN]: Interpret option
        `e' (evaluate, like Perl's but uses Bourne shell).
        * sed/sed.h (struct subst): Add an `eval' flag.

        * sed/compile.c (compile_program): Compile command `e'
        like `c'.
        * sed/execute.c (execute_program): Execute command `e'.

        in-place editing
        * sed/execute.c (backup_file_name): New function to
        support in-place editing
        * sed/main.c (usage, main): Parse -i.
        * sed/utils.c: Moved to lib directory

        * lib/utils.c (temp_file_template): New function.
        * sed/utils.h: Declared temp_file_template.

2001-09-05  Paolo Bonzini  <[email protected]>

        * sed/execute.c (do_subst): `baaac', if passed through
        s/a*/x/g, gave `xbxxcx' rather than `xbxcx' (because an
        empty string matched before the `c'.  Fixed.

        * sed/execute.c: Removed mmap support, I/O is done using
        getline (slower but more bug-proof).
        * sed/utils.c: Likewise.
        * lib/getline.c: New file

2001-03-22  Paolo Bonzini  <[email protected]>

        * sed/compile.c (normalize_text) [POSIXLY_CORRECT]: Enable
        escapes in modes other than BRE.

2001-03-18  Paolo Bonzini  <[email protected]>

        * sed/compile.c (compile_program): Fixed missing break when

        * sed/compile.c (check_final_program): Removed now spurious
        call to compile_regex
        * sed/regex.c (compile_regex): Don't track the last compiled
        regex

        Perl and vi.
        * sed/compile.c (new_replacement): Accept new parameter
        to support \[lLUuE].
        * sed/sed.h (enum replacement_types): New declaration
        * sed/execute.c (do_subst): Use new function str_append_modified
        to apply the changes required via \[lLUuE].
        * sed/execute.c (str_append_modified): New function

2001-03-02  Paolo Bonzini  <[email protected]>

        * sed/compile.c (setup_replacement): Count the number of backreferences
        that the RHS needs
        * sed/regex.c (compile_regex): Check if there is a sufficient number
        of backreferences (new argument needed_sub replaces nosub)
        * sed/compile.c (compile_address, compile_program,
        check_final_program): Callers adjusted

2001-01-03  Paolo Bonzini  <[email protected]>

        * sed/compile.c(snarf_char_class) [REG_PERL]: Don't parse
        `\n' specially
        * sed/compile.c(match_slash) [REG_PERL]: Ditto

        * sed/compile.c(read_text) [REG_PERL]: Support [xX] modifiers
        * sed/compile.c(mark_subst_opts) [REG_PERL]: Ditto

2001-01-04  Paolo Bonzini  <[email protected]>

        * testsuite/Makefile.am: Use automake's implementation
        of `make check'.  Removed the test targets
        * testsuite/Makefile.tests: Moved the test targets here
        (new file).
        * testsuite/runtest: New file

        * testsuite/Makefile.tests: `khadafy' test uses EREs.

        * testsuite/spencer.inp: Removed the ^* test

        * testsuite/spencer.sh: Don't rely on awk; more comments too

2001-01-07  Paolo Bonzini  <[email protected]>

        * sed/compile.c (compile_program): Added `T' (branch if failed)
        * sed/execute.c (shrink_program, execute_program): Ditto

2001-02-08  Paolo Bonzini  <[email protected]>

        * sed/compile.c (compile_program): Added `Q' (quit without output)
        * sed/execute.c (execute_program): Ditto

        * sed/compile.c (compile_program): Fill in exit_status for `q' and `Q'
        * sed/execute.c (execute_program): Return -1 for `go on', 0..255
        to set the exit status
        * sed/execute.c (process_files): Interpret new convention for
        execute_program, return sed's exit code
        * sed/sed.c (main): Return process_files's exit code
        * sed/sed.h (struct sed_cmd): Declare exit_status

2000-12-21  Paolo Bonzini  <[email protected]>

        * lib/snprintf.c [BOOTSTRAP]: Don't include stdio.h
        * lib/strerror.c [BOOTSTRAP]: Don't include stdio.h
        * sed/execute.c [!HAVE_ISATTY]: Don't buffer stdin

2000-12-11  Paolo Bonzini  <[email protected]>

        * sed/compile.c(mark_subst_opts): Support [mMsS] flags
        * sed/compile.c(read_text): Support [MS] flags for
        addresses
        * sed/regex.c(compile_regex): Support arbitrary flags for
        regncomp.

        * sed/regex.c(compile_regex) [REG_PERL]: Don't call
        normalize_text.

2000-12-08  Paolo Bonzini  <[email protected]>

        * basicdefs.h: Moved here from the `sed' subdirectory.

        * configure.in: Removed crap to pick a regex engine.
        Added snprintf to the AC_REPLACE_FUNCS call.

        * lib/snprintf.c: New file.

        * sed/regex.c(compile_regex): Use regncomp
        * sed/regex.c(match_regex): Use regexec2

        * sed/compile.c(compile_program): Implemented the `v' command.

        * sed/sed.c(main): Implemented the `r' and `R' options

        * sed/sed.h: Replaced use_extended_syntax_t with
        extended_regexp_flags to support Perl regular expressions.

        * sed/execute.c(open_next_file): Don't mmap stdin (because
        we cannot seek into it, so a redirected stdin's contents
        would not be "eaten" by sed)

Mon Aug 30 23:40:08 PDT 1999  Ken Pizzini <[email protected]>

        *** Version 3.02.80 released

        * sed/execute.c(do_subst): lib/regex.c(re_search_2) seems to
        want one extra backreference register; humor it.

        * sed/regex.c(compile_regex): work around some odd assumptions
        that lib/regex.c(re_compile_pattern) makes about our desired
        RE syntax.

        * configure.in: tweaked version to 3.02.80; added new entries
        to the ALL_LINGUAS definition.

        * doc/sed.1, doc/sed.texi, BUGS: explicitly request the output
        of sed --version in bug-reporting instructions.

        * doc/sed.texi: the old "informal seders list" is dead; document
        the new sed-users mailing list instead (under Other Resources).


Thu Aug 19 23:27:54 PDT 1999  Ken Pizzini <[email protected]>

        * sed/sed.h: Add explicit #include of "regex-sed.h" (rather
         than relying on parent file doing so); change the "cmd_regex"
         member of sed_cmd: make it a pointer (instead of a struct),
         and change its name to cmd_subst; add prototypes for newly
         exported functions bad_prog(), normalize_text(), compile_regex(),
         match_regex(), and release_regex(); drop rx_testing variable.

        * sed/compile.c: move the compile_regex() function to regex.c;
        export bad_prog() and normalize_text() functions; eliminate the
        rx_testing debris; rename the NOLEAKS symbol to more descriptive
        DEBUG_LEAKS; make cmd_regex to cmd_subst fixes (see above);
        make use of newly abstracted release_regex() function.

        * sed/execute.c: abstract out the regex matching to
        regex.c:match_regex(); NOLEAKS to DEBUG_LEAKS change;
        cmd_regex to cmd_subst structure member name change.

        * sed/execute.c(do_subst): use re_registers/regoff_t instead of
        regmatch_t to hold the backreference registers, make "offset"
        always be relative to the beginning of the string (rather than
        a delta from "start"), defer some matching bookkeeping (e.g.,
        not_bol_p) to match_regex().

        * sed/sed.c(main): loose rx_testing variable; NOLEAKS
        (aka DEBUG_LEAKS) code attempting to release
        _nl_current_default_domain is problematic, so omit it.

        * sed/regex.c: new file --- abstracts out the interface to the
        regex engine so that less conditional code is required in
        compile.c and execute.c, and so as to make a change of engine
        easier; implements compile_regex() (which looks an awful lot
        like the one that used to live in compile.c), match_regex(),
        and (if DEBUG_LEAKS is set) release_regex().

Sun Apr 18 04:40:46 PDT 1999  Ken Pizzini <[email protected]>

        * sed/sed.c(main): conditionalize calls to setlocale() and
        textdomain() to only occur if their support is needed/wanted.

Sun Apr 18 03:01:46 PDT 1999  Ken Pizzini <[email protected]>

        * bootstrap.sh: "foo || bar && baz" was not grouping like I
        expected ("foo || (bar && baz)") under at least one shell,
        so change the test for a pre-existing config.h file to an
        if statement.

        * bootstrap.sh: added -DUSE_REGEX_GNU_H option to the
        compiler invocation, to ensure that we get a usable
        regex library included.

Sun Apr 18 02:59:42 PDT 1999  Ken Pizzini <[email protected]>

        * sed/sed.h, sed/utils.c: conditionalized inclusion of <libintl.h>
        to occur only if ENABLE_NLS is defined.

Sun Apr 18 01:48:45 PDT 1999  Ken Pizzini <[email protected]>

        * sed/compile.c(xofa,normalize_text,convert_number): change
        name of xofa() function to convert_number(); change semantics
        to do all of the work of the text->number conversion.

        * sed/compile.c(normalize_text): add new \dDDD decimal
        and \oOOO octal escapes.

Sun Mar 28 21:05:07 PST 1999  Ken Pizzini <[email protected]>

        * sed/sed.c(main): if NOLEAKS is set, free up a word that
        the call to textdomain() allocated.

        * sed/execute.c(read_file_line): plug up (minor) memory leak:
        if buffer.alloc==0 we may have malloc()'d 1 byte anyway,
        so be sure to FREE(buffer.text) before calling line_init();

Fri Mar 26 16:52:10 PST 1999  Ken Pizzini <[email protected]>

        * sed/compile.c(match_slash): somewhere between 3.02
        and 3.02a we lost the ability to use a newline as
        the s/// delimiter; restore this ability.

        * sed/compile.c(compile_regex): forget about trying
        to cache the compiled form of the last RE --- it
        causes more problems than its worth.  We now only
        cache the source form.

        * testsuite/help.good: update to reflect output containing
        new options.

Sun Dec  6 00:51:23 PST 1998  Ken Pizzini <[email protected]>

        * sed/utils.c(ck_fwrite): fix i18n bug of using a printf
        fragment of "item%s" to handle plural text.

Mon Nov 23 11:03:40 PST 1998  Ken Pizzini <[email protected]>

        * doc/sed.1, doc/sed.texi: ran ispell over these
        files to catch the more obvious typos...

Sun Nov  1 00:09:07 PST 1998  Ken Pizzini <[email protected]>

        * sed/execute.c(do_list): make a `lcmd_out_line_len'
        (--line-length) of zero mean "infinite length",
        i.e., "never wrap".

Sat Oct 31 23:06:50 PST 1998  Ken Pizzini <[email protected]>

        * execute.c(match_an_address_p,process_files),
        compile.c(compile_program): back out the "zero-address"
        changes of 1998-09-27.  It was a neat idea, but there are
        too many dark corners which don't work well.  The
        special code for handling line ranges starting at
        address zero (from 1998-08-31) are still there though:
        this seems to work fine with no surprises.

Sat Oct 31 22:18:59 PST 1998  Ken Pizzini <[email protected]>

        * sed/sed.c, sed/sed.h, sed/execute.c: added new
        `lcmd_out_line_len' variable.  (Idea suggested by
        Carlos J. G. Duarte <[email protected]>.)
        Also added ATOI macro (which uses strtoul() if available,
        with fall-back to atoi()).
        * sed/sed.c(main): attempt to use COLS environment variable
        to set a reasonable `lcmd_out_line_len'; added -l/--line-length
        command-line options to set the new `lcmd_out_line_len' flag.
        * sed/sed.c(usage): documented new -l/--line-length options.
        * sed/execute.c(do_list): use `lcmd_out_line_len' variable
        instead of `LCMD_OUT_LINE_LEN'.
        * sed/execute.c: deleted now obsolete LCMD_OUT_LINE_LEN define.
        * configure.in: added strtoul to the AC_CHECK_FUNCS call.

Sat Oct 31 21:37:17 PST 1998  Ken Pizzini <[email protected]>

        * sed/sed.c, sed/sed.h, sed/execute.c: added new `force_unbuffered'
        flag.  (Idea suggested by Frank Strauss <[email protected]>.)
        * sed/sed.c(main): added -u/--unbuffered command-line options
        to set the new `force_unbuffered' flag.
        * sed/sed.c(usage): documented new -u/--unbuffered options.
        * sed/execute.c: changed the name of the `is_tty' flag in struct
        input to a more generic `no_buffering'; also removed HAVE_ISATTY
        conditional on this member.
        * sed/execute.c(slow_getline): removed HAVE_ISATTY conditonal
        compilation of this function.
        * sed/execute.c(output_line): if force_unbuffered is set,
        then force a fflush() even if writing to stdout.
        * sed/execute.c(open_next_file): added handling of the
        new `force_unbuffered' flag so that slow_getline()
        will always be used for input.
        * sed/execute.c(read_file_line): changed the (conditionally
        compiled) test of `input->is_tty' to (unconditionally)
        use the new spelling `input->no_buffering'.

Thu Oct 15 12:08:09 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: deleted AC_ARG_PROGRAM call; this is already
        done for us by AM_INIT_AUTOMAKE, and we were winding up
        with a doubled-transform.

Sun Sep 27 01:42:42 PDT 1998  Ken Pizzini <[email protected]>

        * compile.c(compile_program): remove special-case code for matching
        address range with a `0' beginning.

        * compile.c(compile_address): change default addr_number to
        be a pragmatically impossible countT value, instead of zero.

        * execute.c: spell macro REGNEXEC() unconditionally instead of
        playing with conditional definition of regnexec() macro.

        * execute.c(match_an_address_p): added third argument (and changed
        callers in match_address_p).  Added special code to ignore
        non-numeric matches when processing "line zero".

        * execute.c(process_files): added a "line zero" pass through the
        commands script.

Sun Sep 27 00:20:53 PDT 1998  Ken Pizzini <[email protected]>

        * compile.c(xofa,normalize_text): new functions.
        * compile.c(compile_regex): cache last_compiled_re (with its
        associated flags); add POSIXLY_CORRECT behavior for empty RE.
        Make use of the new normalize_text() function.
        * compile.c(setup_replacement): Make use of the new normalize_text()
        function.

Sat Sep 26 22:59:13 PDT 1998  Ken Pizzini <[email protected]>

        * lib/regex-gnu.h: added missing prototype for regncomp().

Mon Sep 14 20:47:23 PDT 1998  Ken Pizzini <[email protected]>

        * sed/sed.c(main): use EXIT_SUCCESS instead of 0, in case
        we are built on a system (such as VMS) where EXIT_SUCCESS
        is distinct from 0.

Wed Sep  9 22:17:28 PDT 1998  Ken Pizzini <[email protected]>

        * sed/Makefile.am: added -I../intl the INCLUDES line; if we are
        building in a directory outside the source tree and the system
        we are building on does not have a <libintl.h> header, then
        the build was failing, because libintl.h is a build-time
        constructed source file.

        * configure.in: tweaked version to be 3.02b.

Wed Sep  9 19:28:14 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.02a released

        * sed/compile.c(mark_subst_opts,read_label,compile_program):
        wherever we accept a ; as a command terminator, also allow a } or
        a # to appear.  (This allows for less cluttered-looking scripts,
        such as: sed '/foo/{x;G}' (instead of: sed '/foo/{x;G;}').)

Wed Sep  9 18:17:07 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(compile_regex): use regncomp() instead
        of regcomp(), so that a script with NULs in its REs
        will work in the expected manner.

        * sed/compile.c(ADDNUL,REGNCOMP): added support macros
        for above.

        * lib/regex.c(regncomp,regcomp): added regncomp() and
        made regcomp() a simple wrapper function.

Mon Aug 31 21:48:30 PDT 1998  Ken Pizzini <[email protected]>

        * sed/sed.c(compile_program): if the first address of
        a range is the number 0 (or a 0~N sequence), start
        out in the "a1_matched" state.  This allows one
        to match an initial chunk of a file without undue
        convolutions for handling the case where the match
        for the end of the sequence happens to be the first
        line.

Sun Aug 16 03:34:25 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(snarf_char_class,match_slash): simplify
        handling of "premature newline" error. Also, get the
        line number right in the error message if we encounter
        a "premature newline" during char-class snarfing.

Sun Aug 16 02:59:20 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c: added N_() markers and corresponding gettext()
        (er, _()) calls.

        * Merged in i18n contribution from Erick Branderhorst
        <[email protected]>.  His ChangeLog entry
        for the changes I've incorporated so far:

1998-07-24  Erick Branderhorst  <[email protected]>
        * configure.in (ALL_LINGUAS, AM_GNU_GETTEXT): nl
        * sed/{sed.h,utils.c}: #include <libintl.h> #define _(String)
        gettext (String)
        * sed/sed.c: #include <locale.h>
        * po/POTFILES.in: sed/{compile,execute,sed,utils}.c
        * run gettextize -f
        * acconfig.h: #undef LOCALEDIR ENABLE_NLS HAVE_CATGETS
        HAVE_GETTEXT HAVE_LC_MESSAGES HAVE_STPCPY

Fri Aug 14 13:52:57 PDT 1998  Ken Pizzini <[email protected]>

        * Merged code from 3.02 with a branched development
        tree from late May; the following (out-of-order)
        changelog entry is from the branched tree.

Sat May 30 12:23:16 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c, sed/execute.c: added (conditional on NOLEAKS macro)
        code to free all dynamically allocated memory.

        * sed/sed.c, sed/compile.c, sed/execute.c: much shuffling
        of code --- ordered functions such that no forward
        declarations are necessary, and placed all static prototypes
        immediately before the actual function definition.
        This accomplished two things: first, I find the new ordering
        a more natural way to read the code than the previous
        ordering, and second, the new ordering give the compiler
        a better opportunity to discover inlining possibilities.
        (The odd "prototype declaration+old-style definition"
        style is used because I feel it is the least ugly way
        of supporting K&R1 C while still getting the benefit of
        prototypes when they are available.)

        * sed/basicdefs.h: added MEMCPY() macro to hide the VCAST()s
        that ought to be used with memcpy().

        * sed/execute.c: Change calls to memcpy() to go through the
        new MEMCPY() macro.  Various prototypes: elide variable name
        if it does not add any human-useful documentary information
        to the bare type.

        * sed/sed.c(main): Updated calls to compile_string() to add third
        (length) argument.  Changed call to obsolete close_all_files()
        to a call to the new finish_program().

        * sed/sed.c(map_file): Attempt to clean-up how "size" gets
        cast and tested; remove spurious S_ISREG test (just let
        mmap() fail if it doesn't support the underlying file type).

        * sed/sed.c: Deleted old RX library stub declarations.

        * sed/sed.c(map_file,unmap_file): added VCAST()s to the
        mmap()/munmap() calls.

        * sed/utils.c(ck_fclose): added support for ANSI C
        functionality where passing a NULL argument means
        to fclose() _all_ open streams.  (Well, almost.
        Only closes streams which were previously ck_fopen()ed,
        as I don't care to figure out how to autoconf-detect
        whether fclose(NULL) is properly supported on a given
        platform.)

        * sed/sed.h: Renamed `struct text_buf' member `text_len'
        to `text_length'.  Abstracted out `enum addr_types'
        from `struct addr'; added new enum types num2,step,step_mod;
        renamed mod to num_mod.  De-unionized the regex,number,
        {modulo-offset/step} components of `struct addr', in
        anticipation of new features.  Changed type of `a2' member
        of `struct sed_cmd': now a pointer to save space.
        Abstracted out `struct replacement' from `struct subst'.
        Cleaned up declaration of `x' union of `struct addr'.
        Fixed prototype for compile_string().  Replaced prototype
        for old close_all_files() with one for new finish_program().

        * sed/sed.h, sed/compile.c, sed/execute.c: changed to
        simplify the data structures used for branches and
        command blocks: simplified `struct vector'; made
        `struct label' local to compile.c; `struct sed_cmd'
        was modified to support a simpler design for branches
        and blocks.

        * sed/execute.c: Conditionally added ADDNUL() macro so that
        the function call overhead is only incurred if nul_append()
        _must_ be called.  Made some commentary edits, including
        typo fixes.
        * sed/execute.c(resize_line): changed semantics of "len" argument
        from "additional length" to "target length"; made
        INITIAL_BUFFER_SIZE a minimum allocation length.
        * sed/execute.c(str_append): adjusted to new resize_line()
        semantics.
        * sed/execute.c(line_copy): use FREE()+MALLOC() instead of
        REALLOC() to avoid unnecessary copying of old text; add the
        "try doubling first" allocation heuristic (just like
        resize_line() does).
        * sed/execute.c(line_exchange): new function.
        * sed/execute.c(nul_append): make whole function (not just its
        body) conditional on HAVE_REGNEXEC macro; adjust to new
        resize_line() semantics.
        * sed/execute.c(read_mem_line): use str_append() instead if
        custom in-line code; compensate for new default of
        "line.chomped = 0" in read_pattern_space() by setting
        "line.chomped = 1" where appropriate.
        * sed/execute.c(read_file_line): use different trigger to
        determine that "buffer" is uninitialized, and do a full
        initialization if required; use str_append() instead of custom
        in-line code in two places; compensate for new default of
        "line.chomped = 0" in read_pattern_space() by setting
        "line.chomped = 1" where appropriate.
        * sed/execute.c(output_line): don't bother calling ck_fwrite()
        if length==0.
        * sed/execute.c(release_append_queue): new function.
        * sed/execute.c(dump_append_queue): use release_append_queue()
        instead of in-line equivalent.
        * sed/execute.c(read_pattern_space): conditionalize call to
        dump_append_queue() for alleged performance reasons; changed
        default "line.chomped" value to more common "1", and added an
        assignment of "0" where this made a difference.
        * sed/execute.c(match_an_address_p): deleted "is_addr2_p"
        argument; reorder cases to match order in enum declaration; add
        cases for new "addr_is_num2", "addr_is_step", and
        "addr_is_step_mod" address types; alter nul_append() call to be
        through ADDNUL() macro; fix to new struct member and enum
        spellings in (formerly addr_is_mod); addr_is_num_mod case.
        * sed/execute.c(match_address_p): remove oblsolete third argument
        to calls to match_address_p(); alter references to sed_cmd
        member a2 to reflect new pointer status; add new support for
        a2->addr_type addr_is_step and addr_is_step_mod cases.
        * sed/execute.c(do_subst): add NOLEAKS support logic; use
        ADDNUL() wrapper to nul_append(); simplify replacement
        expansion by using the new "struct replacement" data structure;
        use line_exchange() function instead of custom in-line code.
        * sed/execute.c(process_files): added NOLEAKS code.
        * sed/execute.c(execute_program): updated implementations
        of the `{', `}', `:', `b', and `t' commands; modified
        `c' command gratuituosly; fixed potential memory
        overrun in `D' command.  Simplified how nonstandard
        `loop increments' work.  Use line_exchange() instead of
        custom in-line code in 'x' case.
        * sed/execute.c[EXPERIMENTAL_DASH_N_OPTIMIZATION conditional
        code]: various modifications intended to keep this
        code in sync with the new changes, but the code still
        retains its previous bugs.

        * sed/compile.c: use "exit(EXIT_FAILURE) instead of "exit(1)",
        just in case we get compiled under VMS.
        * sed/compile.c: Change type of prog_info.base to decrease needs
        for casting; then elimiated the casts in question ;-).
        * sed/compile.c: Added struct sed_label (moved from sed.h, then
        modified).
        * sed/compile.c: Removed "readit_p" flag from struct fp_list.
        * sed/compile.c: Added module-global "blocks" variable.
        * sed/compile.c: Extracted more error-message constant strings
        to named variables.
        * sed/compile.c(check_final_program): updated to
        reflect new data structures and use new fucntions.
        Added call to compile_regex() to release unneeded
        memory.
        * sed/compile.c: deleted obsolete new_vector() function;
        abstracted new read_label() function; abstracted new
        release_label() function; added new `blocks' module-static
        variable.
        * sed/compile.c(compile_program): updated implementations
        of the `{', `}', `:', `b', and `t' commands; modified
        initialization from NULL vector.
        * sed/compile.c(compile_regex): added mechanism to
        release memory consumed by the cached `last' RE.
        * sed/compile.c(setup_jump,setup_label): updated
        name (from setup_jump to setup_label) and prototype;
        changed body to reflect data structure changes.
        * sed/compile.c: Add OPEN_BRACE and CLOSE_BRACE macros for better
        "vi" editing behavior.
        * sed/compile.c(compile_filename,read_filename,get_writefile):
        Replaced function compile_filename() with more orthogonal functions
        read_filename(), get_writefile().
        * sed/compile.c(compile_regex): Added ability to free the remembered
        "last RE" in compile_regex (for benifit of "NOLEAKS" code).
        * Made adjustments dictated by the change to struct sed_cmd which made
        the a2 member a pointer-to-addr instead of an addr.
        * sed/compile.c(setup_jump,read_label,setup_label,release_label):
        Added functions read_label(), setup_label(), release_label(); deleted
        function setup_jump().
        * sed/compile.c(new_replacement,setup_replacement,release_replacement):
        new functions.
        * sed/compile.c: Adjusted to new spelling of text_buf member
        ("text_length" instead of "text_len").
        * sed/compile.c(new_vector): deleted function.  (Due to new handling
        of blocks, only one instance remained, and that one was just as
        clear in-lined.)
        * sed/compile.c(compile_string): Added third argument; it now
        takes a counted string instead of a NUL-terminated string.
        * sed/compile.c(compile_file): added variable "map_base" to
        compensate for new type of prog_info.base.
        * sed/compile.c(check_final_program): reflect new style of
        handling blocks and struct sed_label.
        * sed/compile.c(close_all_files,finish_program): replaced function
        close_all_files() with more generic finish_program().
        * sed/compile.c(read_text): added new feature: if first non-blank
        character after the {a,i,c} command character is not "\", then
        use the trailing text on that line as the (first) line of text.
        Also added code conditional on NO_INPUT_INDENT to support the
        "feature" of stripping leading blanks from each input line; I
        do not read POSIX as permitting this behavior, nor do I think
        it is a good idea, so it is disabled by default, but some have
        argued that this blank-stripping is the "correct" behavior, so
        I offer them the option of building their sed that way.
        * sed/compile.c(compile_address): added xxx,+n and xxx,~n addressing;
        simplified code.
        * sed/compile.c(compile_program): added BAD_PLUS error detection;
        adjusted to new cur_cmd->a2 pointer status; added addr_is_num2
        detection; deleted pointless "a2->addr_number < a1.addr_number"
        check (addr_is_num2 semantics handle this just fine); updated
        code for '{', '}', ':', 'b', and 't' to reflect new design
        of branch handling, including making use of new functions
        related to the new design); added support for feature already
        mentioned in read_text() where {a,i,c} commands are able to have
        their text start on the same line as the command; changed some
        error messages (hopefully for the better); localized variables
        specific to individual commands (particularly 's' and 'y');
        made use of new setup_replacement() function in 's' command.

Mon Aug 10 19:58:49 PDT 1998  Ken Pizzini <[email protected]>

        * doc/sed.texi, doc/sed.1: sedtut10.txt is apparently dead.
        Deleted references to it and added a pointer to
        http://seders.icheme.org/tutorials/.  (Pointed out by
        Joerg Heitkoetter <[email protected]>.)

Sat Aug  8 18:11:57 PDT 1998  Ken Pizzini <[email protected]>

        * djgpp/config.btm: per request by Michel de Ruiter
         <[email protected]>, added "%1" to "%9" parameters.

Mon Aug  3 11:44:55 PDT 1998  Ken Pizzini <[email protected]>

        * doc/sed.texi: fix a couple of typos.  (Submitted by
        Alan Modra <[email protected]>.)

Sat Aug 01 17:49:06 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.02 released

        * configure.in: Because of code change in 3.01a, bump the
        minor revision number for the release (now 3.02).

Sun Jul 26 16:07:55 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01a released

        * sed/compile.c(snarf_char_class):  the POSIX char-class
        recognition loop forgot to update its concept of "prev"
        as the loop progressed.

        * testsuite/Makefile.am: The dependency of version.good
        on [testsuite/]Makefile introduced in the previous
        release was botched -- it referred to "Makefile"
        as "$(srcdir)/Makefile, which of course doesn't work
        if you aren't building in the source tree.

        * djgpp/Makefile.am: add forgotten "config.btm" EXTRA_DIST
        member.

        * configure.in: update version.

Tue Jul 21 06:04:42 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01 released

        * configure.in: mark as release version!

        * Makefile.am: add BUGS and THANKS to the EXTRA_DIST target.

        * testsuite/Makefile.am: add dependency of version.good
        on [testsuite/]Makefile.

Mon Jul 20 12:38:10 PDT 1998  Ken Pizzini <[email protected]>

        * djgpp/config.btm: New file to support the 4DOS alternative
        to command.com.  (Sumitted by Eli Zaretskii on behalf of
        an anonymous 4DOS user.)

Fri Jul 17 00:36:34 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta18 released

        * djgpp/config.sed: my "tweak" in beta17 was too
        hastily considered.  Back it out.

        * configure.in: update to beta18.

Wed Jul 15 01:02:15 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta17 released

        * djgpp/config.sed: tweak/simplify s,,, commands at end.

        * configure.in: update to beta17.

1998-07-14  Eli Zaretskii  <[email protected]>

        * djgpp/config.sed: Edit all the occurences of = in the context of
        --option=value, including in the help messages, into
        --option:value, but leave DOS-style d:/foo/bar file names intact.

        * djgpp/config.bat: Use --srcdir:foo instead of --srcdir=foo.

        * testsuite/Makefile.am (help, version): Remove temporary files
        explicitly, don't use shell wildcards, so it works under DOS 8+3
        limits.

Thu Jul  9 13:06:00 PDT 1998 16:51:43 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta16 released

        * djgpp/config.sed: tweak the configure script to use :
        instead of = for --with-foo=bar option parsing, to
        work around problems with how command.com handles =s.

Wed Jul  8 16:51:43 PDT 1998  Ken Pizzini <[email protected]>

        * djgpp/config.bat: correct inappropriate behavior that I
        introduced in the beta13 changes (if first argument is
        a directory, it needs to be handled as the --srcdir).

        * testsuite/version.gin, testsuite/version.good, testsuite/Makefile.am:
        Add target to automake to automatically update version.good
        from (new file) version.gin, instead of hand-editing the version
        number each release.

        * testsuite/Makefile.am: miscellaneous gratuitious tweakage --
        mainly adding $(RM) commands just because I didn't like
        leaving the tmp* files from successful runs laying about.
        Also some editorial comments.

        * configure.in: update to beta16.  Added and commented out
        experiment with AC_OUTPUT() for testsuite/version.good.
        Added code to properly handle bare (without =xxx)
        "--with-regex" option.

Sun Jul  5 21:02:16 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta15 released

        * sed/utils.c(ck_fflush), sed/utils.h, sed/execute.c(output_line):
        add and use new ck_fflush() function.

Sun Jul  5 15:23:47 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(bad_prog): add more detail to error
        messages about -e strings.

Sun Jul  5 14:29:45 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(mark_subst_opts), sed/execute.c(do_subst):
        Define better semantics for interaction of the `g' flag
        with a numeric flag to the s/// command.  It used to
        be that the `g' command siezed control; now the first
        (number-1) matches are skipped and then `g' gets control
        after that.  (It is not clear whether this is a feature
        sneaking in during late beta, or a bug fix; the changes
        involved were trivial, so I decided to treat it as a bug
        fix.)

        * configure.in, testsuite/version.good: update to beta15.

Sat Jul  4 09:54:45 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta14 released

        * sed/basicdefs.h, sed/compile.c, sed/execute.c:
        per report by "Kaveh R. Ghazi" <[email protected]>,
        copied the ISXXX macros from lib/regex.c so that
        silly machines which require isascii() to be true
        before the other isXXX() macros are valid will
        still work.

        * configure.in, testsuite/version.good: update to beta14.

Thu Jul  2 23:46:13 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta13 released

        * configure.in, acconfig.h: set USE_REGEX_GNU_H symbol if we
        are going to be using lib/regex.c.

        * lib/Makefile.am, lib/regex.h, lib/regex-gnu.h, lib/regex.c:
        rename lib/regex.h to lib/regex-gnu.h, so that those who
        choose to use a different regex implementation will not
        pick-up lib/regex.h when doing "#include <regex.h>".

        * sed/regex-sed.h, sed/Makefile.am, sed/compile.c, sed/execute.c,
        sed/sed.c: create sed/regex-sed.h which acts as a switch
        to choose either lib/regex.h or the user-supplied <regex.h>,
        depending on the value passed to configure's --with-regex=
        option.

Thu Jul  2 17:22:31 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: if an alternative --with-regex= is given,
        do an AC_CHECK_FUNCS(regnexec regexec) to ensure that
        at least one of these functions is available.  Also,
        parallel changes for the default case.

        * sed/execute.c, acconfig.h: retire use of the WITH_REGNEXEC
        test macro in favor of HAVE_REGNEXEC test macro created
        by above change.

        * djgpp/config.bat: Play games to handle "install-sh",
        DOS filename restrictions, GNU makefile default rules,
        and getting a correct run of "configure" (contributed
        by Eli Zaretskii <[email protected]>).

        * djgpp/Makefile.am, testsuite/Makefile.am, testsuite/Makefile.in,
        Makefile.am, configure.in: Various automake targets
        (such as distcheck) failed with old configuration.
        The simplest solution was to just add these .am
        files.  (The testsuite/Makefile.in was just renamed to
        testsuite/Makefile.am, then various redundant defines and
        targets were deleted.)  (Reported by Erick Branderhorst
        <[email protected]>.)

        * testsuite/dc.good, testsuite/dc.inp: per suggestion from
        Greg Ubben <[email protected]>, use base 16 output to
        exercise even more of the dc.sed script.

        * configure.in, testsuite/version.good: update to beta13.

Sun Jun 28 16:21:02 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta12 released

        * doc/sed.texi: Avoid mixing @code and @samp markups together:
        they look ugly in Info.  Use @url and @email instead of @example.
        Add indexes.  (Basis of changes contributed by Eli Zaretskii.)

        * djgpp/*, Makefile.am: add support for the DJGPP compiler,
        contributed by Eli Zaretskii <[email protected]>.

        * dc.sed, testsuite/Makefile.in, testsuite/dc.inp, testsuite/dc.good:
        added this remarkable script, written and contributed
        by Greg Ubben <[email protected]>, both as a work of
        art for general admiration, and also for use in regression
        testing.

        * configure.in, lib/Makefile.am: add --with-regex=regexlib
        option, which overrides the use of lib/regex.c.

        * configure.in, testsuite/version.good: update to beta12.

Fri Jun 12 16:41:48 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta11 released

        * sed/compile.c: add module-static variables first_script
        (for #n change below) and pending_text (for a/c/i change
        below).

        * sed/compile.c(compile_file), sed/compile.c(compile_program):
        Instead of having #n trigger the -n option in *any file*,
        have #n trigger the -n option only if they are the first
        two bytes of the first script or script-file.

        * sed/compile.c(compile_string), sed/compile.c(compile_file):
        clear the first_script variable at end of these functions.

        * sed/sed.h: tease out the struct text_buf declaration from
        struct sed_cmd, so that a pointer to such can be passed
        to new sed/compile.c(read_text) function.

        * sed/compile.c(compile_program), sed/compile.c(read_text):
        Tease out handling of text to a/c/i commands to new
        read_text() function.  Handle (via aid of pending_text
        variable) texts which span more than one script/script-file
        option.  In particular, restore the ability to have this
        work:  sed -e '1i\' -e 'foo'

        * sed/compile.c(check_final_program): close off any dangling
        pending_text allocation.

Thu Jun 11 11:17:46 PDT 1998  Ken Pizzini <[email protected]>

        * sed/execute.c(do_subst): fixed two bugs: s/ */X/g was failing
        to match the final empty string after the end of the pattern
        space; and /^foo$/s/o/x/3p was printing, despite the failure
        to do a substition.

Fri Jun  5 04:40:24 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: change the AC_ARG_WITH(regnexec, ...)
        to be the more appropriate AC_ARG_ENABLE(regnexec, ...).

        * configure.in, testsuite/version.good: update to beta11.

Fri Jun  5 00:54:25 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta10 released

        * sed/execute.c: forgot to P_() the prototype and
        old-style the declaration for bootstrap_memchr()!

Thu Jun  4 18:42:30 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(snarf_char_class): added code to
        recognize \n or \<newline> sequence within a
        char-class as the newline character.

Tue Jun  2 11:56:02 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: added check for <sys/types.h> and
        a AC_ARG_WITH(regnexec,...) check, to simplify use
        of other regex libraries which have regexec() but
        not regnexec(), with the corresponding loss of
        functionality (regexps will not work right against
        input lines which contain NULs).

        * sed/execute.c: add nul_append() function, a #define
        for a regnexec() -> regexec() macro (conditional on
        the lack of the WITH_REGNEXEC symbol), and a couple
        of calls to nul_append() (in match_an_address_p()
        and do_subst()) to permit the use of the POSIX standard
        regexec() function call instead of the suggested
        regnexec() call.

        * sed/compile.c, sed/execute.c, sed/sed.c: check for
        <sys/types.h> and include it (before "regex.h") if
        available.  This makes it simpler to use the system's
        regex library instead of the one in lib/regex.c, should
        that be desired.

Tue Jun  2 08:41:05 PDT 1998  Ken Pizzini <[email protected]>

        * sed/basicdefs.h: define VCAST macros to allow sed to
        compile on systems which predate the definition
        of "void *", and yet still get feedback about
        stupid programming errors from systems which *do*
        know about "void *"s.  Also define MALLOC, REALLOC,
        MEMDUP, and FREE macros to keep under control the
        degree of code ugliness which would otherwise be
        introduced in making use of the VCAST macro.

        * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c:
        pervasively use the new VCAST, MALLOC, REALLOC, MEMDUP,
        and FREE macros wherever appropriate.

        * sed/utils.c, sed/utils.h: correct type of first arguments
        to ck_fread() and ck_fwrite() to be [const] VOID *.

        * sed/basicdefs.h, sed/execute.c: protect against
        the rumored systems which stupidly #define __STDC__ 0.

        * testsuite/help.good, testsuite/Makefile.in: make
        the ``help'' test insensitive to the spelling of
        the executable's name.  Also, enhanced `make clean'
        target.

        * doc/sed.texi, doc/sed.1: correct documentation of `q'
        command; fix typos.

        * configure, testsuite/version.good: update to beta10.

Sat May 30 17:28:00 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta9 released

        * Makefile.am: make testsuite a normal SUBDIR.

        * configure.in: discontinue using AC_ISC_POSIX --
        check for -lcposix library instead; added
        testsuite/Makefile to AC_OUTPUT list.

        * lib/memmove.c(memmove): fixed wrong sense used
        for HAVE_BCOPY test.

        * sed/execute.c: checked more specifically for a version
        of gcc which supports __attribute__ (i.e., >= 2.7).

        * testsuite/*: renamed files to fit 14 char limit.

        * testsuite/Makefile, testsuite/Makefile.in: Makefile
        renamed to Makefile.in and then modified so that
        "make -j check" from top directory will work.

        * testsuite/subwrite.sed, testsuite/writeout.sed: changed
        file name of the "w" command to be consistent with the
        new naming used in testsuite/Makefile.in.

        * doc/sed.1, doc/sed.texi: fixed some typos, formatting
        glitches, and poor wordings.

Sat May 30 04:02:29 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: specify that config.h is to be derived
        from config_h.in in order to avoid the braindead
        DOS file system limitations.

Fri May 29 21:56:30 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(compile_address), doc/sed.texi: gave
        a better definition to the meaning of N~0 address
        forms -- N~M addresses now mean that lines match
        when there exists a non-negative x such that
        lineno == N+x*M.

Fri May 29 12:07:38 PDT 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(compile_address),
        sed/execute.c(match_an_address_p): update semantics of
        N~M address form: now N is the first line which will
        match and M is the step between succeeding matches.
        If N<M this works out to the same as before, but the
        new behavior for N>=M seems more useful.

        * doc/sed.1, doc/sed.texi: update documentation of N~M
        address form; added "Other Resources" node to sed.texi;
        minor formatting changes to some items in sed.1 with
        an eye to improving clarity.

        * configure.in, testsuite/version.good: update to beta9.

Sat May 23 20:04:31 HST 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta8 released

        * sed/compile.c(compile_regex): forgot to make last_re be
        a *copy* of the buffered text in today's earlier fix.

        * sed/execute.c(read_file_line): EOF check was wrong --
        it forgot to allow for the possibility that we were
        appending to the end of the ``line'' (instead of merely
        reading a fresh line).

Sat May 23 18:07:18 HST 1998  Ken Pizzini <[email protected]>

        * sed/compile.c(compile_regex): don't track compiled version
        of regex -- the modifiers may change.  Track the regex
        source instead.  (For "last regex" (aka //) notation.)

        * configure.in, testsuite/version.good: update to beta8.

Sat May 23 16:07:09 HST 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta7 released

        * sed/execute.c: #undef'd EXPERIMENTAL_DASH_N_OPTIMIZATION
        because its code is buggy.

Tue May 19 17:03:52 HST 1998  Ken Pizzini <[email protected]>

        * sed/sed.c: label rx library code as such with #ifdefs
        (instead of just #if 0).

        * sed/compile.c(compile_program): make incremental
        improvement to the "Unknown command" error message.

Sat May 16 23:16:26 HST 1998  Ken Pizzini <[email protected]>

        * testsuite/Makefile: simplify: get rid of automatic run
        against system's sed; don't time by default; allow for
        alternative comparison command.

        * configure.in, testsuite/version.good: update to beta7.

Wed May 13 21:44:28 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta6 released

        * lib/Makefile.am: fix spelling of libsed_a_LIBADD in
        libsed_a_DEPENDENCIES.

        * configure.in, testsuite/version.good: update to beta6.

Wed May 13 14:38:08 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta5 released

        * sed/execute.c(do_subst): added not_bol_p variable to track when
        we have iterated past the beginning of the pattern.
        [Thanks to Jim Meyering <[email protected]> for the bug report.]

Wed May 13 13:54:04 PDT 1998  Ken Pizzini <[email protected]>

        * sed/execute.c(bootstrap_memchr): new function.  When
        bootstrapping we don't know if we are on a 64-bit machine,
        so lib/memchr.c breaks.  Supply this (slow) implementation
        just to get us bootstrapped.

        * bootstrap.sh: add a #define BOOTSTRAP symbol; add -I.
        for emphasis for the compiles in sed/; be explicit
        about what files we're bothering to compile.

        * configure.in, testsuite/version.good: update version
        to beta5.

Wed May 13 06:39:06 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta4 released

        * rename writeout.good? to wrtout?.good and subwrite.good? to
        subwrt?.good to comply with DOS 8+3 file name restrictions.
        [Eli Zaretskii <[email protected]> suggested this to
        simplify DJGPP ports, and it was easy.]

        * testsuite/Makefile: reflect above name changes.

Wed May 12 21:09:32 PDT 1998  Ken Pizzini <[email protected]>

        * sed/sed.c(usage): fix non-portable omission of \n\ at end of
        lines within long string.

        * sed/sed.c(main): remove spurious argument to fprintf() in the
        'V'ersion output.

        * sed/execute.c(line_append): embed newline between the two
        text fragments unconditionally.

        * sed/execute.c(do_subst): change structure assignment to memcpy()
        (for portability reasons).

        * README.bootstrap: suggest using -w option.

Tue May 12 10:02:37 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: use AC_REPLACE_FUNCS where appropriate.

        * lib/Makefile.am: updated to reflect AC_REPLACE_FUNCS change in
        configure.in.

        * lib/memchr.c lib/memcmp.c: revert to standard GNU versions.

        * lib/alloca.c: added this missing file.

        * testsuite/version.good: updated for new version identifier.

Mon May 11 18:50:56 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta3 released

        * sed/Makefile.am: fix INCLUDES to work right with VPATH.
        [Thanks to Jim Meyering <[email protected]> for the bug report.]

        * sed/sed.c(usage): make --help output more user-friendly?

        * sed/execute.c(execute_program): fix bug in 'x' command introduced
        in the alleged portability fix of May 9.

        * configure.in: update version to 3.01-beta3.

        * testsuite/version.good, testsuite/help.good: freshen with
        latest output.

Sat May  9 22:35:45 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta2 released

        * sed/sed.c: add #include <sys/types.h> in HAVE_MMAP
        block (needed on some machines).

        * lib/memmove.c: #include <memory.h>, if HAVE_MEMORY_H.

Sat May  9 21:29:00 PDT 1998  Ken Pizzini <[email protected]>

        * configure.in: remove dangling references to rx library;
        added HEADER and FUNC checks for items used by source in
        lib/.

        * lib/ansidecl.h, lib/memcopy.h, lib/pagecopy.h, lib/string.h
        lib/memcpy.c, lib/memmove.c: deletes these files.  There
        are still pieces of glibc missing to support these, and
        it isn't worth the headache right now.

        * lib/memmove.c: de novo, simpler version.  Uses bcopy()
        if available, and slow-but-simple code if not.

        * lib/Makefile.am: remove references to deleted files.
        Added forgotten reference to memcpy.c.  Re-ordered
        SOURCE entries to reflect dependencies for systems
        which lack ranlib.

        * sed/basicdefs.h: updated to reflect above changes to lib/,
        and experience with non-STDC compilers.

        * lib/regex.c: made regerror() function publicly visible.

        * lib/strerror.c: use old-style function declaration.

        * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
        sed/sed.h, sed/utils.h: ensure that private definitions of
        some symbols do not cause problems when #include'ing system
        headers (mainly by re-ordering the #include directives).
        (This is particularly an issue for bootstrap.sh runs.)

        * sed/execute.c (execute_program): use memcpy() instead of
        structure assingment ('x' command), for portablility to
        old compilers.

        * sed/execute.c (slow_getline): use old-style function
        declaration, with a P_ prototype.

        * sed/sed.c: change the type of the fallback MAP_FAILED
        definition to work on archaic systems.  (Modern systems
        should be defining it themselves, so the change from
        void * shouldn't be a problem.)

        * bootstrap.sh, README.bootstrap: actual testing of bootstrap
        code revealed that I was too optimistic.  Redesigned and
        replaced implementation.

        * testsuite/Makefile: ignore errors from reference-implementation
        seds that aren't up to snuff.

        * testsuite/help.good, testsuite/version.good: update to
        current version's output.

Fri May  8 15:08:28 PDT 1998  Ken Pizzini <[email protected]>

        *** Version 3.01-beta1 released

        * sed/sed.c (main, usage): once again tweak the --help and
        --version output to bettery comply with GNU coding standards.

        * testsuite/help.good, testsuite/version.good: update to
        reflect above change.

        * doc/sed.texi: fix "Invoking" node's spelling to comply
        with GNU standards.

Fri May  8 11:43:10 PDT 1998  Ken Pizzini <[email protected]>

        * doc/sed.1, doc/Makefile.am: wrote (very basic) man page.

Thu May  7 20:40:21 PDT 1998  Ken Pizzini <[email protected]>

        * lib/Makefile.am, lib/memmove.c, lib/memchr.c, lib/regex.c,
        lib/memcpy.c, lib/regex.h, lib/memcopy.h, lib/string.h,
        lib/pagecopy.h, lib/ansidecl.h: grab yet-another-version
        from gnu.org for baseline and/or edit copyright boilerplate
        using official lgpl2gpl.sed script.  Take care not to
        loose regnexec() interface or special conditional-compilation
        code.

Wed May  6 23:35:12 PDT 1998  Ken Pizzini <[email protected]>

        * lib/regex.c, lib/regex.h: take from grep-2.1 distribution,
        then trivially added the regnexec() interface.

        * sed/sed.c, sed/compile.c, sed/execute.c: made modifications
        to work with regex instead of rx.

        * rx/*: deleted directory; the code is just too slow.
        I think it will be easier to extend regex to fully
        support POSIX.2 than to tune rx to be reasonable.
        Even if this supposition is wrong, I'd rather make
        the 3.01 release with the slightly deficient regex.

        * Makefile.am lib/Makefile.am, sed/Makefile.am: made changes
        related to the substitution of regex for rx.

        * lib/Makefile.am, sed/Makefile.am: since regex is not a
        ``compatability'' module, changed name of library to
        ``libsed.a''.

        * lib/memchr.c, lib/memcpy.c, lib/memmove.c: add conditional
        compilation code to leave zero-sized .o file if system
        already supports the implemented function.

        * testsuite/help.good, testsuite/version.good: brought
        up-to-date (once again).

        * NEWS, ANNOUNCE: changes to reflect this batch of changes.

Wed May  6 18:40:47 PDT 1998  Ken Pizzini <[email protected]>

        * sed/execute.c: discovered awful bug in '}' handling:
        it could read past the end of vec (because `n' was
        being decremented below zero)!  Needed to "continue"
        instead of "break".

Tue May  5 14:34:38 PDT 1998  Ken Pizzini <[email protected]>

        * doc/sed.texi, doc/version.texi: wrote some rudimentary
        texinfo documentation.

        * ANNOUNCE, NEWS, README, README.rx, Makefile.am:
        more updates for the upcoming beta-release.

        * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
        sed/sed.h, lib/strerror.c: update copyright notice text.

Fri May  1 15:41:37 PDT 1998  Ken Pizzini <[email protected]>

        * sed/execute.c (match_an_address_p, match_address_p): if
        the second element of an address range is a line number,
        and that line number is *less than* (or equal to) the
        current line number, we only match the one line (per
        POSIX.2, section 4.55.7.1).  [Bug discovered as reported
        in the seders mailing list FAQ.]

        * AUTHORS, NEWS, acconfig.h, configure.in, doc/Makefile.am,
        lib/Makefile.am, sed/Makefile.am, lib/README,
        testsuite/help.good, testsuite/version.good:
        Updated in anticipation of the 3.01-beta1 release.
        Reorganized development source tree to make creation
        of a distribution simpler.  Most notable changes were
        to the various Makefile.am files and configure.in, but
        some minor edits (such as deleting or changing #include
        directives) have been made in many other source files.

        * bootstrap.sh, README.bootstrap: created a mechanism for
        creating sed on a system which lacks a working sed.

Thu Apr 16 23:52:11 PDT 1998  Ken Pizzini <[email protected]>

        * sed.h, sed.c, execute.c, compile.c: did a spell-check on
        the comments; fixed several typos.

Thu Apr 16 13:43:01 PDT 1998  Ken Pizzini <[email protected]>

        * execute.c (do_subst): fixed bug where the "replaced" flag
        was being set to one inappropriately when at least one
        but fewer than sub->numb matches of the regexp were found.
        (Thanks to Simon Taylor <[email protected]>
        for the bug report.)

Wed Apr 15 11:35:31 PDT 1998  Ken Pizzini <[email protected]>

        * sed.h, sed.c, compile.c, execute.c: having a concern that
        a cast was being done inappropriately, and realizing that
        there is no quick way to locate all casts in a program, I
        went through and marked all casts with a simple macro.
        Now it is a simple matter to locate the casts, and it is
        also a simple matter to turn of casts for a lint session
        (if it should be desired).

Wed Apr 15 10:29:21 PDT 1998  Ken Pizzini <[email protected]>

        * compile.c, sed.c: redo compile phase so that brace
        expressions can be spread across multiple files.
        For example:
          printf '{' >a; printf 'l;d' >b; printf '}' >c
          sed -f a -f b -f c foo
        will now compile (and work), instead of complaining
        about an unmatched '{'.  The mess created in compile.c
        allowed a little simplification to the command-line
        processing of "-e" options in sed.c.

        sed.h: added (opaque) err_info member to struct vector;
        added comments to the members of struct vector.

Wed Apr 14 23:50:50 PDT 1998  Ken Pizzini <[email protected]>

        * sed.h, sed.c, compile.c, execute.c: added types countT and
        flagT in order to clarify what various "int"s were doing.
        Also makes it easy to change the type used for counts
        (for example, to "unsigned long long") if desired, although
        there are still some gotchas (such as the printf() format
        for the '=' command).

Tue Apr 14 17:34:54 PDT 1998  Ken Pizzini <[email protected]>

        * execute.c (execute_program, process_files, count_branches,
        shrink_program): Added a first attempt at program optimization.
        We now can quit early if we are running with the "-n"
        and all of the commands are known to be valid only for
        lines less than the current line.  Thus the "sed" in
        "foo | sed -n 1,2p" will print read three lines, printint
        the first two, and then quit, regardless of how much longer
        "foo" might run or output.  This optimization does not buy
        much in most cases (it sometimes even costs a little),
        but when it does help it can help big.  The code is
        all conditionally compiled based on the
        EXPERIMENTAL_DASH_N_OPTIMIZATION symbol being #defined,
        so it can be easily omitted if it causes problems.

Tue Apr 14 12:25:06 PDT 1998  Ken Pizzini <[email protected]>

        * execute.c (test_dollar_EOF, last_file_with_data_p):
        test_dollar_EOF() was incorrectly returning a false (0)
        when there were unprocessed files, none of which had any
        data (either unopenable or zero-length).  Created
        last_file_with_data_p() to detect this situation, and
        modified test_dollar_EOF() to make use of it.

Thu Apr  2 23:02:18 PST 1998  Ken Pizzini <[email protected]>

        * compile.c (match_slash): match_slash() did not handle
        [.coll.], [=equiv=], and [:class:] sequences within a
        character class.  Added snarf_char_class() [which is a
        remote derivative of parse_char_class() from GNU ed-0.2]
        to deal with the details, and altered match_slash()
        to make use of it.  Also created the trivial
        add_then_next() to avoid clutter in snarf_char_class().

Thu Apr  2 20:34:42 PST 1998  Ken Pizzini <[email protected]>

        * execute.c, sed.c, sed.h: There was a severe bug in
        how the code handled "sed 5n a b" when "a" consists
        of exactly five lines -- it behaved like "sed 5q a b"!

        Rearranged where files get opened -- large scale
        changes primarily involving main(), process_files(),
        and read_pattern_space(), but also touching on several
        other parts of execute.c.  The read_pattern_space()
        function became unwieldly and parts were split into
        open_next_file(), closedown(), read_always_fail(),
        read_mem_line(), and read_file_line().  The
        at_end_of_file_p() function became obsolete and was
        eliminated; test_dollar_EOF_p() was updated.  A few
        global and module-static variables were elminated, and
        "struct line" was extended; comments were added to the
        "struct line" declartation to document some important
        dependencies in it.

        I undertook the reorganization with dread, but I
        feel that the new organization is an improvement
        well beyond just fixing the bug that inspired it.

Thu Apr  2 01:16:25 PST 1998  Ken Pizzini <[email protected]>

        * execute.c (read_file_line, slow_getline): the fread()
        buffering code gives insufficient feedback to a user
        running sed with a tty input device, so I created
        slow_getline() for reading from a tty device.
        Additionally, EOF detection has been made a little more
        sensitive to avoid requiring multiple EOFs to be entered
        from a tty.

        * configure.in: added isatty() check.

Wed Apr  1 11:04:30 PST 1998  Ken Pizzini <[email protected]>

        * configure.in (CPPFLAGS, LDFLAGS, LIBS):
        Set to appropriate values if large file support needs
        explicit enabling.  Code fragment taken from a 1997-10-25
        patch to gawk by Paul Eggert <[email protected]>

Thu Aug 14 17:43:27 PDT 1997  Ken Pizzini <[email protected]>

        * utils.c (ck_fclose): modified to ignore NULL parameter.

Thu Aug 14 12:08:45 PDT 1997  Ken Pizzini <[email protected]>

        * execute.c: tweaked execute_program() to eliminate
        gratuitous "goto" usage.

Thu Aug 14 11:30:04 PDT 1997  Ken Pizzini <[email protected]>

        * compile.c: added case-insensitive modifier ('I') to
        address and s/// regexps.  The s/// case also accepts
        the more popular 'i' modifier.  (The address regexp
        cannot use 'i' as a modifier, as that conflicts with
        the use of the 'i'nsert command.)

Thu Aug 14 09:29:06 PDT 1997  Ken Pizzini <[email protected]>

        * compile.c: abstracted out match_slash() from the s///, y///,
        and address-regexp special-case codes.

        * execute.c: made dump_append_queue() use ck_fread() instead
        of hand-rolled error checking.

Mon Jul 28 10:50:41 PDT 1997  Ken Pizzini <[email protected]>

        * sed.c, sed.h, execute.c: POSIX.2, section 4.55.7, says that
        a newline must end *every* output line.  But I think that
        it is useful (when seding a binary file) to omit a trailing
        newline if the input lacks one.  Thus the addition of
        POSIXLY_CORRECT behavior.

        * execute.c: however, when seding multiple files my feeling
        is that it makes sense to have each file but the last
        behave as-if it ended in a newline.  Modified read_pattern_space()
        accordingly.

        * utils.c: realized that add1_buffer(), for performance reasons,
        shouldn't be calling memcpy() (indirectly via add_buffer()),
        so rewrote it.

Sat Jul 26 23:08:28 PDT 1997  Ken Pizzini <[email protected]>

        * execute.c: attempted to make read_pattern_space more
        efficient for the the non-mmap() case.

        * utils.c, utils.h, execute.c: new function ck_fread()
        created and used.

Sat Jul 26 20:22:14 PDT 1997  Ken Pizzini <[email protected]>

        * execute.c, compile.c, sed.c: abstracted the mmap()
        interface into map_file()/unmap_file() [sed.c], and
        changed the ad-hoc code in compile_file() [compile.c]
        and process_file() [execute.c] to make use of the new
        interface.

Sat Jul 26 19:45:46 PDT 1997  Ken Pizzini <[email protected]>

        * execute.c, compile.c, configure.in: Check to see if mmap()
        is available; if so make use of it on regular files.

        * compile.c: compile_file() now closes the input file
        when it is through!

Sun Jul 20 23:57:02 PDT 1997  Ken Pizzini <[email protected]>

        * compile.c: modified parsing to permit whitespace in more
        places where it makes sense;
        added backslash escaping to the y/// command, per POSIX.

        * execute.c: Merged append_pattern_space() into read_pattern_space();
        moved body of 's' command to new function do_subst();
        moved body of 'l' command to new function do_list();
        changed output of 'l' command to conform to POSIX.2;
        made line handling conform to POSIX; added output_line() function;
        redesigned append-space algorithm; added append_queue structure and
        the next_append_slot() and dump_append_queue() functions.

        * sed.h: moved the definition of what is now struct subst
        outside of the definition of struct sed_cmd.

Sat Jul 19 16:29:09 PDT 1997  Ken Pizzini <[email protected]>

        * sed.c, execute.c, sed.h, Makefile.am: Separated out the
        pieces dealing with executing the program from the top-level
        parameter parsing and control.

Sat Jul 19 01:16:35 PDT 1997  Ken Pizzini <[email protected]>

        * sed.c, compile.c, sed.h, Makefile.am: separate out the
        pieces dealing with compiling the program from the pieces
        dealing with interpreting the result.

        * compile.c: add functions in_nonblank() and in_integer(),
        and change interface to compile_address() with an eye
        to making code clearer.

Fri Jul 18 13:35:50 PDT 1997  Ken Pizzini <[email protected]>

        * utils.c: attempt at a quasi-unification of the
        STDC and traditional C approaches to panic().

        * sed.c: eliminate some gratuitous bit twiddling.
        (Using flag bits can be a useful technique, but
        this code is cleaner without them.)

        * sed.c: place mutually exclusive members of struct addr
        within a union, mainly to document the exclusivity;
        eliminate unused structure members from struct fp_list;
        eliminate unnecessary module-global variables;
        remove some #if 0 code that is too odd to keep;
        allegedly simplified the 'l' case of execute_program();
        allegedly simplified inchar();
        localized some static variables;
        renamed some variables to better document their purpose;
        removed some goto-s rendered obsolete by other changes.

Thu Jul 17 15:30:44 PDT 1997  Ken Pizzini <[email protected]>

        * utils.c, utils.h, sed.c: added and made use of
        ck_free() function.

        * utils.c, utils.h, sed.c: changed all the *_buffer()
        functions to take/return an incomplete type
        "struct buffer *" instead of using VOID *.

        * utils.c, utils.h, sed.c: renamed "finish_buffer()"
        to "free_buffer()", on the premise that the new
        name better describes the function's purpose.

Wed Jul 16 13:52:14 PDT 1997  Ken Pizzini <[email protected]>

        * utils.c, utils.h, sed.c: added and made use of
        ck_memdup() function.

        * sed.c: protected a call to add1_buffer() in
        compile_program() which could have tried to
        push an EOF if a a/i/c command ended with
        a '\', EOF sequence.

        * utils.c: added sanity check to add1_buffer() so that
        EOF will not be added to the buffer.

Wed Jul 16 03:56:26 PDT 1997  Ken Pizzini <[email protected]>

        * configure.in, compat.h, compat.c: added memchr.

        * sed.c: got rid of arbitrary NUM_FPS limit;
        made global functions and variables "static" where appropriate;
        make various cosmetic changes, hopefully improving readability;
        simplified some redundant predicates;
        simplified some code, but nothing fundamental (yet?).

Wed Jul 16 00:24:54 PDT 1997  Ken Pizzini <[email protected]>

        * alloca.c, getopt.c, getopt.h, getopt1.c: updated from
        versions in textutils-1.22.

        * Makefile.in, Makefile.am, configure.in: put in automake support.

        * basicdefs.h, compat.h, compat.c [, sed.c, utils.c]: took out
        some very ugly compatibility #ifdefs and packaged into one
        place.

        * sed.c, utils.c: some gratuitous formatting changes.

        * utils.c: changed datatype of utils_id_s in order to
        eliminate arbitrary array size.

Sun Jul 13 17:00:26 PDT 1997  Ken Pizzini <[email protected]>

        * sed.c, utils.c, utils.h: de-linting oriented cleanup.

Sun Jul 13 00:46:48 PDT 1997  Ken Pizzini <[email protected]>

        * sed.c: fixed bug which caused SEGV for files missing a
        final newline.  Corrected calls to regnexec to pass the
        proper parameters, in the proper order.

Sat Dec 30 20:16:59 1995  Tom Lord  <lord@beehive>

        *** Version 3.00 released

        * sed.c: Use posix entry points to regexp functions.
        Fix enough bugs to pass the test-suite.

....... Jason Molenda  <[email protected]>

        * testsuite/: trippy test suite.


Wed May 11 07:46:24 1994  Chip Salzenberg  ([email protected])

        *** Version 2.05 released

        * sed.c (compile_address): Recognize numeric addresses.
        Fixes typo made during installation of "~" feature.

Sat Apr 30 17:17:38 1994  Tom Lord  ([email protected])

        *** Version 2.04 released

        * sed.c: applied a patch from
         From: [email protected] (Dietrich Kappe)

         Dietrich writes:

         As my contribution to the creeping feature creature in sed,
         here is a new type of address. The address has form n~m,
         which means "the line number is equal to n modulo m." The
         modifications to sed are trivial, and the general
         usefulness of this address should be obvious. If m is 0 or
         missing, 1 is used in its place (could be a bug or a
         feature :-).

Sat Apr 30 17:17:38 1994  Tom Lord  ([email protected])

        * rx.c (solve_destination): protect `solution' more carefully.
        This is a cleanup of a patch from Kevin Buettner
         ([email protected]).

Sat Apr 30 17:17:38 1994  Tom Lord  ([email protected])

        * rx.c: make translation tables unsigned chars

        * sed.c (main): Compile accumulated -e commands as
        soon as a -f command comes along.  This ensures that
        the commands are executed in the right order.

Mon Oct 25 14:41:47 1993  Tom Lord  ([email protected])

        * sed.c (execute_program): 'w' flushes the buffer after it
        writes -- diagnosed by [email protected].  'r' and 'w' to
        the same file is now supported -- hopefully even in a way that
        satisfies Posix (it now behaves differently from some
        /bin/sed's and the spec is hard to read so i'm not sure).

        Also, 'r' of a non-existent file is now permitted.

Mon Oct 11 21:06:10 1993  Tom Lord  ([email protected])

        * sed.c (execute_program): remember that 'b' and 't' are more
        like longjmp than goto.  Patch from [email protected] (Tom
        R.Hageman)

        * rx.c: patch from From: [email protected] (Chip
        Salzenberg) to get rid of compiler warnings.


Sat Aug  7 01:04:59 1993  Tom Lord  ([email protected])

        *** Version 2.03 released

        * sed.c (compile_regex): report error messages for bogus
        regexps.

        SEE ALSO:  ChangeLog.rx



Wed Jul 21 00:28:03 1993  Tom Lord  ([email protected])

        * alloca.c: upgraded to a more recent version

        * rx.c (re_search_2): prefer matches with longer
        subexpressions to those with shorter ones, giving precedence
        to low numbered subexpressions.

        * rx.c (re_compile): don't free `params' if its null.

Fri Jul 16 01:12:08 1993  Tom Lord  ([email protected])

        * rx.[ch], sed.c: rx replaces regex.



Thu May 27 11:13:03 1993  Tom Lord  ([email protected])

        * sed.c (execute_program, match_addr): caught more cases
        that need to be sensitive to a missing \n at EOF.

Fri May 21 00:39:22 1993  Tom Lord  ([email protected])

        * sed.c (execute_program): apply gaumondp's patch
        to fix '\xabcxs/foo/bar/'.

        * sed.c (execute_program):
        If a second address is a regexp, never match it on the
        same line as the first address.

        * sed.c (compile_regexp):
        Numeric ranges  x,y s.t. y < x are now treated as x,x.
        There was a bug in that they were being handled like x,x+1.

        * sed.c (execute_program, read_pattern_space,
        append_pattern_space) don't add newlines to lines
        that don't have them.

Wed May 19 13:34:45 1993  Tom Lord  ([email protected])

        * sed.c (compile_program): grok \\n in comments.

Mon May 17 16:34:50 1993  Tom Lord  ([email protected])

        * alloca.c: new (standard) file

        * configure.in: AC_CONSTified

        * sed.c (compile_program): properly diagnose the error of
        a missing command (e.g. sed /x/). (thanks gaumondp)

        * sed.c (compile_regexp): handle character classes correctly.
        Thanks [email protected]
        and  [email protected].

Thu May  6 12:37:18 1993  Tom Lord  ([email protected])

        * sed.c (compile_filename, execute_program): don't use
        `access' or `/dev/null'.

        * sed.c (execute_program): 'N' at EOF should delete the pat buf.

        * sed.c (compile_filename): truncate, don't append files
        being openned for `w' or `s///w'

        * sed.c (execute_program): -n switch shouldn't effect `i' or `c'.

        * sed.c (compile_program): don't compile unescaped newlines
        into the substitution string of an `s' command (they are an error).

        * sed.c (compile_regex): correctly skip over character
        sets that contain `]'.

        * sed.c (execute_program): patch from gaumondp
        Correctly handle empty-string matches in the case of an `s'
        command with a repeat count.

        * sed.c (compile_program): patch from [email protected].
        Don't consume characters after the label of a `b', `t' or `:' command.

        * sed.c (compile_program): unmatched open braces are an error.

        * sed.c (compile_file): when consuming an initial comment,
        count lines correctly.

Wed Nov 18 02:10:58 1992  Tom Lord  ([email protected])

        * sed.c (execute_program): Made s///p print even if -n was
        specified.

        * sed.c (compile_string): Changed the type of this function to
        fix a compile warning.

Wed Nov  4 17:15:34 1992  Tom Lord  ([email protected])

        * sed.c (main): Initialize the hold area to contain "\n"
        instead of "".  In execute_program, all lines are expected
        to be newline terminated.  Also, if H is the first command
        in the script, the result is a pattern buffer that begins
        with a blank line.  Thanks to [email protected]
        (Francois Pinard) for pointing out this and many other bugs.

        * sed.c (execute_program): Fixed a case of `D' command.
        Thanks Chris Weber <[email protected]>

        * sed.c: added new tests of no_default_output to make -n work.
        Thanks Andrew Herbert <[email protected]>

        * sed.c, configure.in,Makefile.in: autoconfed bcopy and const.
        Thanks "J.T. Conklin" <[email protected]>

        * sed.c: made prog_cur, prog_start, and prog_end unsigned so
        that users could write  `sed -e s/ÿ/foo/g'.

Tue Oct 13 00:04:05 1992  Tom Lord  ([email protected])

        * sed.c (execute_program): fixed the cycling behavior of 'D'

        * sed.c: integrated patch that closes files

        * sed.c: changed regexp syntax

Fri May 22 15:11:12 1992  Tom Lord  (lord at moriarty.bh.andrew.cmu.edu)

        * regex.c:  this is not my change, but a pointer to the fact
        that karl@gnu fixed some regexp bugs that were plaguing sed.

Thu Apr 30 13:02:21 1992  Tom Lord  (lord at unix3.andrew.cmu.edu)

        * sed.c (compile_program, execute_program)
        subprograms are now compiled with an explicit continuation ;)
        return_v and return_i in struct vector.  execute_program
        no longer recurses to execute subprograms (case '{') and now
        understands a return instruction (case '{').

Tue Apr 28 17:13:04 1992  Tom Lord  (lord at unix7.andrew.cmu.edu)

        * sed.c (compile_address) added \?regexp? syntax for addresses.

        * sed.c (main) added {} intervals to the obscure regexp
        syntax.

        * sed.c (compile_program)  after calling compile_address,
        normalize numeric addresses (make a2.addr_number > a1.addr_number).
        This is necessary because line numbers must match exactly,
        but sed does not try to match a2 until after a1 has matched,
        yet a1,a2 where a2 <= a1 is defined to be equivelent to
        a1,a1+1

Sat Feb 29 10:55:54 1992  David J. MacKenzie  (djm@nutrimat)

        * sed.c (usage): Document long options as starting with `--'.

Mon Dec  9 23:56:40 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

        * sed.c: Include sys/types.h, for new regex.h.

Tue Nov  5 02:16:01 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

        * utils.c: Change NO_VFPRINTF to VPRINTF_MISSING, for
        compatibility with autoconf.

Mon Sep  2 22:02:40 1991  David J. MacKenzie  (djm at apple-gunkies)

        * sed.c (compile_regex): Treat \ as a normal character when in
        a char class.

Thu Aug  8 00:15:33 1991  David J. MacKenzie  (djm at bleen)

        * Version 1.08.

        * sed.c (compile_filename): If reading a file fails, read
        /dev/null instead.  It's what Unix and POSIX do, effectively.

        * sed.c (compile_regex): The 'slash' character doesn't
        terminate the regex if it's in a character class.

        * sed.c (main): If given no args, or bad option, print usage
        message.
        (usage): New function.

        * sed.c (execute_program): Amount written for 'P' command was
        wrong.  From [email protected] (Stephen Davis).

Wed Aug  7 16:51:14 1991  David J. MacKenzie  (djm at apple-gunkies)

        * sed.c (append_pattern_space): Check for buffer full before
        instead of after writing to buffer.  Don't need to test for
        EOF initially anymore, due to the next change.
        (execute_program): For 'n' and 'N' commands, if eof is reached
        in input, quit the script like Unix sed does.
        Fix memory allocation problems for 'a' and 'r' commands.
        (compile_program): Fix off by one error in processing comments.
        All of the above are from Tapani Tarvainen, [email protected].

        * sed.c (setup_jump): Use isblank instead of testing for ' '
        or '\t', for POSIX locales.

        * utils.c (ck_strdup): Renamed from strdup.
        * sed.c: Change callers.

        * sed.c, utils.c: Clean up declarations and includes to get
        rid of compiler warnings.

        * sed.c (main): Add long-named options.  Don't complain if -n
        is given twice.

Fri Aug  2 12:33:16 1991  David J. MacKenzie  (djm at apple-gunkies)

        * configure: Support +srcdir arg.  Create config.status and
        remove it and Makefile if interrupted while creating them.
        * Makefile.in: Change DESTDIR to prefix.

Mon Jul 15 13:07:39 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

        * sed.c (main): Add -V option to print version number.
        (USAGE): Mention -V.

Mon Jul  8 01:42:22 1991  David J. MacKenzie  (djm at geech.gnu.ai.mit.edu)

        * sed.c: Define bcopy in terms of memcpy if STDC_HEADERS as
        well as if USG.
        (compile_filename): Don't glob filename (for 'r' and 'w'
        commands).  Unix sed doesn't do it and it's not very useful,
        since it can only match 0 or 1 files.
        (execute_program): Change '\a' to 007 since some compilers
        don't recognize \a.
        * utils.c: New file; code moved from sed.c.
        * Replace Makefile with Makefile.in and configure.
        Update README.

        * sed.c (match_address)  Added a trivial cast for portability.

Mon Feb 25 13:23:29 EST 1991    Jay Fenlason ([email protected])

        * sed.c  Changed 's' command to work with latest version of regex()
        routines, which mysteriously changed somewhere in there. . .
        A one-line patch from David Eckelkamp ([email protected]).

        Initialize the fastmap in the hopes that it'll make sed faster.

Thu Feb 21 13:42:27 EST 1991    Jay Fenlason ([email protected])

        * sed.c Change panic to compile with other __STDC__ compilers.

Wed Jan 30 10:46:38 EST 1991    Jay Fenlason ([email protected])

        * sed.c  Changed version number.  Made new release.

Tue Nov 27 15:34:51 EST 1990    Jay Fenlason ([email protected])

        * sed.c (setup_jump)  Don't blow chunks if there isn't a label
        after a b or t command.

                (main) Don't panic if it a branch command doesn't have
        a label to branch to.

                (main)  Collect all the -e arguments together and parse them
        all at once.  This way, -e { -e mumble -e } will work.

        All these small patches from David Schmidt ([email protected])

Tue Sep 11 12:51:37 EDT 1990    Jay Fenlason ([email protected])

        * sed.c Changed some function forward declarations to use VOID *
        instead of char *

Mon Jul 16 11:12:54 EDT 1990 Jay Fenlason ([email protected])

        * sed.c (ck_malloc)  Use malloc(1) instead of malloc(0) if given
        a request for zero bytes.

Tue Jun  5 02:05:37 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

        * sed.c: Remove excess newlines from calls to panic.
        Reformat some comments to fit in 79 columns.
        Base whether to use void * on __STDC__, not __GNU__.
        (main): Add missing arg when printing usage message.
        Print usage if given invalid arg.
        (panic) [__STDC__]: Add missing ", ...".
        (compile_filename): Print correct error message if glob_filename
        returns NULL.

Thu Apr  5 21:41:12 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

        * sed.c (execute_program, case 'r'): When need to realloc append.text,
        multiply append.alloc by 2 instead of adding
        cur_cmd->x.cmd_txt.text_len.

Tue Mar  6 15:55:35 EST 1990 Jay Fenlason ([email protected])

        * sed.c (compile_regex)  Allocate 10 bytes extra space needed by
        re_compile_pattern.

Sun Feb 25 16:32:10 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

        * sed.c (execute_program, case 'l'): Print \00 instead of \0.
        Print backslash as \\ not \.
        Print \xx instead of /xx.

Thu Feb  1 14:02:28 EST 1990            hack@wookumz

        * sed.c (memchr)  Use () inside inner loop so it will work correctly.
        A two character patch from Robert A Bruce ([email protected])

Wed Sep 27 18:47:39 EDT 1989            [email protected]

        * sed.c (compile_regex)  New function.  When compiling regex,
        turn ^ into \` and $ into \' so that they won't match on embedded
        newlines.  UN*X pattern matching is a crock.
        (compile_program, compile_address) call compile_regex.

Mon Sep 18 10:15:32 EDT 1989            [email protected]

        * sed.c (compile_program):  define translate as unsigned char * so
        that y command will work on non-ascii characters.

        Changed version number to 1.06.

Thu Sep 14 15:57:08 EDT 1989            [email protected]

        * sed.c  (compile_program)  Let programs use ; to terminate } as
        well as newline.

        (read_file) Print an error msg to stderr if it can't open an
        input file.

        * Makefile, sed.c: Added new copyright notice.

        * Makefile: Make distributions which follow the symlinks.
