+
+	* editline.3, el.c, el.h, histedit.h, terminal.c, vi.c: [Prereq for
+	  PR bin/58609] Add EL_GETENV to libedit
+
+	  When interacting with the shell, and perhaps other applications,
+	  editline needs to obtain the values of some environment
+	  variables.
+
+	  Normally getenv(3) does that - but that doesn't work when being
+	  used in sh(1) as getenv() simply accesses the environment as it
+	  was when sh(1) was invoked - after that, in sh anyway, that
+	  environment is simply abandoned (well, kind of) - but certainly
+	  no changes made by the shell will be reflected there.
+
+	  To allow editline to obtain current values of environment
+	  variables, add a new el_set()/el_get() "op" parameter value,
+	  which can be used to instruct editline which function to use for
+	  the purpose.	 That is EL_GETENV.
+
+	  This is part of a (long pending, awaiting testing) fix for PR
+	  bin/58609 - but I'm getting tired of having it sitting
+	  uncommitted in my source tree - and I think this part is self
+	  contained, and simple enough, to simply commit.

+
+	  This change makes the signal handler respect existing choices
+	  better. Specifically, this allows signal handlers to be set when
+	  the process includes a Go runtime, since Go enforces that all
+	  signal handlers in the process use the SA_ONSTACK flag (e.g. see
+	  golang/go#20400).

+
+	* history.c: Don't fchmod(fileno(fp), ...) in history_save_fp().
+
+	  There are two reasons for this, first, the permissions of the
+	  history file should be able to be set by the user, not forced to
+	  0600 every time the history file is overwritten (or appended to).
+
+	  And more importantly, the fp used for fileno(fp) might have come
+	  from fmemopen() or funopen() (etc) - none of which put a file
+	  descriptor in the "fd" field (ie: fileno(fp) == -1).
+
+	  To compensate for that, when a history file is opened (in
+	  history_save()) set the default permissions then - if the file is
+	  actually created.  As fopen() cannot do that (it simply uses
+	  0666&~umask) create the (normal type) of fp using (approximately)
+	  fdopen(open(...), ...) where the open supplies the 0600 default
+	  permissions that are desired here (which might still be
+	  restricted even more by the umask).	Callers using
+	  history(...,H_SAVE_FP,...) or history(...,H_NSAVE_FP,...) now
+	  need to look after any permission setting required themselves
+	  (but as the doc says absolutely nothing about that, one way or
+	  the other, what happens in this area has always been unspecified,
+	  and still is)
+
+	  One "feature" of the fchmod() method is lost here - apart from
+	  forcing the 0600 permissions (which isn't really desirable) that
+	  fchmod() would also have failed if the current (effective) uid is
+	  not the owner of the history file (or root).	  If that is
+	  required, a test for it could be added later - the effect would
+	  be as it has always been, the file named must have been writable
+	  (or its directory writable if the file did not exist) the open
+	  would occur (potentially truncating the file) after which the
+	  fchmod() would be attempted, possibly failing, and if so, never
+	  writing anything.   Any new uid test would work the same way.

+
+	  The file name matching code in libedit tries to adjust to the
+	  presence of explicit " or ' characters in the input line, but
+	  tries too hard.  Remove a conditional that goes overboard, and
+	  causes the completion code to fail if a quoted string is seen
+	  before the filename to be expanded, as in
+
+		    grep 'foo' bar<TAB>
+
+	  Before this change, the above would not expand any possible
+	  completions, even if they existed, because it would choose to
+	  look for files whose names started with " bar".

+
+2016-06-02 17:11  christos
+
+	* readline.c: From Ingo Schwarze:
+
+	  In libedit, the only way how H_ENTER can fail is memory
+	  exhaustion, too, and of course it is handled gracefully,
+	  returning -1 from history().	So of course, we will continue to
+	  handle it gracefully in add_history() as well, but we are free to
+	  decide what to do with the library state in this case because GNU
+	  just dies...
+
+	  I think the most reasonable course of action is to simply not
+	  change the library state in any way when add_history() fails due
+	  to memory exhaustion, but just return.
+
+	  If H_ENTER does not fail, we know that the history now contains
+	  at least one entry, so there is no need any longer to check the
+	  H_GETSIZE return value.  And we can of course always set
+	  current_history_valid.
+
+	  While testing these changes, i noticed three problems so closely
+	  related that i'd like to fix them in the same diff.
+
+	   1. libedit has the wrong prototype for add_history().
+	      GNU readline-6.3 defines it as void add_history(const char
+	  *).
+	      Of course, that is very stupid - no way to report problems to
+	      the caller!  But the whole point of a compatibility mode is
+	      being compatible, so we should ultimately change this.
+	      Of course, changing the prototype of a public symbol requires
+	      a libedit major bump.  I don't want to do that casually.
+	      Rather, i will take a note and change the prototype the next
+	      time we need a libedit major bump for more important reasons.
+	      For now, let's just always return 0.
+
+	   2. While *implicitely* pushing an old entry off the history
+	      increments history_base in GNU readline, testing reveals that
+	      *explicitly* deleting one does not.  Again, this is not
+	      documented, but it applies to both remove_history() and
+	      stifle_history().  So delete history_base manipulation
+	      from stifle_history(), which also allows to simplify the
+	      code and delete two automatic variables.
+
+	   3. GNU readline add_history(NULL) crashes with a segfault.
+	      There is nothing wrong with having a public interface
+	      behave that way.	Many standard interfaces do, including
+	      strlen(3).  Such crashes can even be useful to catch
+	      buggy application programs.
+	      In libedit/readline.c rev. 1.104, Christos made add_history()
+	      silently ignore this coding error, according to the commit
+	      message to hide a bug in nslookup(1).  That change was never
+	      merged to OpenBSD.  I strongly disagree with this change.
+	      If nslookup(1) is still broken, that program needs to be
+	      fixed instead.  In any case, delete the bogus check; hiding
+	      bugs is dangerous.

+
+	* el.h, keymacro.c, read.c: From Ingo Schwarze:
+
+	  Reduce obfuscation of errno handling. There is only one purpose
+	  non-local errno handling is needed for:  Inside el_wgets(),
+	  several functions call down indirectly to el_wgetc(), many of
+	  them via the dispatch table.	When el_wgetc() fails, it does
+	  properly report failure, but then various cleanup is done which
+	  may clobber errno.  But when returning due to failure, el_wgets()
+	  wants to have errno set to the reason of the original read
+	  failure, not to the reason of some subsequent failure of some
+	  cleanup operation.  So el_wgetc() needs to save errno, and if
+	  it's non-zero, el_wgets() needs to restore it on failure.
+
+	  This core logic is currently obscured by the fact that el_errno
+	  is set and inspected at some additional places where it isn't
+	  needed.  Besides, since el_wgetc() and and el_wgets() are both in
+	  read.c, el_errno does not need to be in struct editline, it can
+	  and should be local to read.c in struct el_read_t.
+
+	  Let's look at what can be simplified.
+
+	   1. keymacro_get() abuses el_errno instead of having a proper
+	      error return code.  Adding that error return code is easy
+	      because node_trav() already detects the condition and an
+	      adequate code is already defined.  Returning it, testing
+	      for it in read_getcmd(), and returning with error from there
+	      removes the need to inspect el_errno from el_wgets() after
+	      calling read_getcmd().
+	      Note that resetting lastchar and cursor and clearing
+	  buffer[0]
+	      is irrelevant.  The code returns from el_wgets() right
+	  afterwards.
+	      Outside el_wgets(), these variables are no longer relevant.
+	      When el_wgets() is called the next time, it will call
+	  ch_reset()
+	      anyway, resetting the two pointers.  And as long as lastchar
+	      points to the beginning of the buffer, the contents of the
+	      buffer won't be used for anything.
+
+	   2. read_getcmd() doesn't need to set el_errno again after
+	  el_wgetc()
+	      failure since el_wgetc() already did so.	While here, remove
+	      the silly "if EOF or error" comments from the el_wgetc()
+	      return value tests.  It's a public interface documented in a
+	      manual, so people working on the implementation can obviously
+	      be expected to know how it works.  It's a case of
+
+		count++;  /* Increment count. */
+
+	   3. In the two code paths of el_wgets() that lead up to "goto
+	  noedit",
+	      there is no need to save the errno because nothing that might
+	      change it happens before returning.
+
+	  For clarity, since el_wgets() is the function restoring the
+	  errno, also move initializing it to the same function.
+
+	  Finally, note that restoring errno when the saved value is zero
+	  is wrong.  No library code is ever allowed to clear a previously
+	  set value of errno.  Only application programs are allowed to do
+	  that, and even they usually don't need to do so, except when
+	  using certain ill-designed interfaces like strtol(3).
+
+	  I tested that the behaviour remains sane in the following cases,
+	  all during execution of el_wgets(3) and with a signal handler for
+	  USR1 installed without SA_RESTART.
+
+	   * Enter some text and maybe move around a bit.
+	     Then send a USR1 signal.
+	     The signal gets processed, then read_char() resumes reading.
+	     Send another USR1 signal.
+	     Now el_wgets() sets errno=EINTR and returns -1.
+
+	   * Press Ctrl-V to activate ed-quoted-insert.
+	     Then send a USR1 signal.
+	     The signal gets processed, then read_char() resumes reading.
+	     Send another USR1 signal.
+	     ed_quoted_insert() returns ed_end_of_file(), i.e. CC_EOF,
+	     and el_wgets() returns 0.
+
+	   * Press a key starting a keyboard macro.
+	     Then send a USR1 signal.
+	     The signal gets processed, then read_char() resumes reading.
+	     Send another USR1 signal.
+	     Now el_wgets() sets errno=EINTR and returns -1.
+
+	   * Press : to enter builtin command mode.
+	     Start typing a command.
+	     Then send a USR1 signal.
+	     The signal gets processed, then read_char() resumes reading.
+	     Send another USR1 signal.
+	     Now c_gets() returns -1, ed_command() beeps and returns
+	  CC_REFRESH,
+	     and el_wgets() resumes operation as it should.
+
+	  I also tested with "el_set(el, EL_EDITMODE, 0)", and it returns
+	  the right value and sets errno correctly.

+
+	* chared.c, chared.h, common.c, el.c, read.c, read.h: Stop the read
+	  module from poking the el_chared.c_macro data structure currently
+	  belonging to the chared module.  The read module does so from
+	  three of its functions, while no other module uses the macro
+	  data, not even the chared module itself.  That's quite logical
+	  because macros are a feature of input handling, all of which is
+	  done by the read module, and none by the chared module.  So move
+	  the data into the read modules's own opaque data structure,
+	  struct el_read_t.
+
+	  That simplifies internal interfaces in several respects: The
+	  semi-public chared.h has one fewer struct, one fewer #define, and
+	  one fewer member in struct el_chared_t; all three move to one
+	  single C file, read.c, and are now module-local.  And the
+	  internal interface function ch_reset() needs one fewer argument,
+	  making the code of many functions in various modules more
+	  readable.
+
+	  The price is one additional internal interface function,
+	  read_end(), 10 lines long including comments, called publicly
+	  from exactly one place: el_end() in el.c.  That's hardly an
+	  increase in complexity since most other modules already have
+	  their *_end() function, read.c was the odd one out not having
+	  one.

+
+	  which maybe isn't completely clear, a plausible implementation is

+	  history_set_pos(), i.e. that it is 0 for the oldest entry and
+	  increases with time, and that's how the GNU implementation
+	  behaves indeed.
+
+	  The libedit implementation, on the other hand, returns 1 for the

+
+	* editline.3, editline.7, readline.c: GNU readline(3) regards
+	  history chronologically, that is, from the perspective of the
+	  dawn of time, so "next" means "newer" and "previous" means
+	  "older".  Libedit, by contrast, uses reverse chronology and
+	  regards history from the perspective of the present, such that
+	  "next" means "longer ago" and "previous" means "not so long ago".
+
+	  The following patch fixes previous_history() and next_history()
+	  as proposed by Bastian Maerkisch.
+
+	  But there is a related problem demonstrated by Bastian's
+	  regression tests that his patch did not fix:	next_history() can
+	  advance not only to the newest entry, but beyond it, which core
+	  libedit cannot do.  So that feature must be implemented locally
+	  in readline.c.
+
+	  With that, the last of Bastians tests is fixed,
+	  test_movement_direction().
+
+	  This patch also improves libedit documentation to more clearly
+	  state what "previous" and "next" mean.  GNU readline
+	  documentation is just as unclear, but we can't easily fix that
+	  since libedit doesn't include its own readline.3 manual.
+
+	  (Ingo Schwarze)
+
+2016-05-09 23:25  christos
+
+	* readline.c: The libedit implementation of history_get() also
+	  differs from the GNU implementation:	libedit goes to the entry
+	  with the given number stored in the HistEvent structure, while
+	  GNU subtracts history_base, then advances that many entries from
+	  the oldest one.  If entries were removed in between, GNU advances
+	  further than libedit.
+
+	  The call sequence H_CURR, H_DELDATA, H_CURR, H_NEXT_EVDATA looks
+	  weird, as if part of that must somehow be redundant.	But
+	  actually, the user interface is so counter-intuitive that every
+	  single step is really required.
+
+	   - The first H_CURR is needed to be able to go back after an
+	  error.
+	   - The H_DELDATA is needed to move the cursor.  Even though it
+	  takes
+	     a pointer to ev, that structure is not filled in when the call
+	     succeeds.	H_DELDATA only moves the cursor, it doesn't tell us
+	     the new event number.
+	   - Consequently, the second H_CURR is required to get ev.num
+	  filled
+	     in.  But it doesn't return the data because ev has no field
+	  for
+	     that.
+	   - So even though the cursor is already positioned correctly,
+	     H_NEXT_EVDATA is needed as the final step merely to get the
+	  data.

+	  (and a functional error) in c_gets(), file chared.c.
+
+	  Run any program using libedit in the default way.  At the
+	  el_[w]gets() prompt, invoke ed-command (for example, in emacs
+	  mode, press the escape key, then type the letter 'x').  You
+	  should see a ": " prompt.  Type the letter 'x' again.  Now press
+	  the backspace key a few times, looking at the screen after each
+	  key press:
+
+	   - The 1st BS deletes the 'x'.
+	   - The 2nd BS deletes the blank after the prompt.
+	   - The 3rd BS deletes the colon of the prompt.
+	   - The 4th BS moves the cursor up one line.
+	   - The 5th BS gives me "Segmentation fault (core dumped)".
+
+	  Depending on your platform, it might take a few more or a few
+	  less backspaces for the buffer underrun to trigger the segfault,
+	  but you should be able to hit it sooner or later no matter what.
+
+	  Run the same program again, connect again and invoke ed-command
+	  again.  Now type: 'b', backspace, 'i', backspace, 'n', backspace,
+	  'd', enter.  The "bind" command gets executed, even though you
+	  deleted what you typed before hitting enter.

+
+	* chartype.h, eln.c: From Ingo Schwarze:
+
+	  el_getc() for the WIDECHAR case, that is, the version in eln.c.
+	  For a UTF-8 locale, it is broken in four ways:
+
+	   1. If the character read is outside the ASCII range, the
+	  function
+	      does an undefined cast from wchar_t to char.  Even if wchar_t
+	      is internally represented as UCS-4, that is wrong and
+	  dangerous
+	      because characters beyond codepoint U+0255 get their high
+	  bits
+	      truncated, meaning that perfectly valid printable Unicode
+	      characters get mapped to arbitrary bytes, even the ASCII
+	  escape
+	      character for some Unicode characters.  But wchar_t need not
+	      be implemented in terms of UCS-4, so the outcome of this
+	  function
+	      is undefined for any and all input.
+
+	   2. If insufficient space is available for the result, the
+	  function
+	      fails to detect failure and returns garbage rather than -1 as
+	      specified in the documentation.
+
+	   3. The documentation says that errno will be set on failure, but
+	      that doesn't happen either in the above case.
+
+	   4. Even for ASCII characters, the results may be wrong if
+	  wchar_t
+	      is not using UCS-4.

+	  makelist, map.c, parse.c, refresh.c, refresh.h, search.c,
+	  search.h, terminal.c, terminal.h, tty.c, vi.c: From Ingo
+	  Schwarze:
+
+	  As we have seen before, "histedit.h" can never get rid of
+	  including the <wchar.h> header because using the data types
+	  defined there is deeply ingrained in the public interfaces of
+	  libedit.
+
+	  Now POSIX unconditionally requires that <wchar.h> defines the
+	  type wint_t.	Consequently, it can be used unconditionally, no
+	  matter whether WIDECHAR is active or not.  Consequently, the
+	  #define Int is pointless.
+
+	  Note that removing it is not gratuitious churn.  Auditing for
+	  integer signedness problems is already hard when only fundamental
+	  types like "int" and "unsigned" are involved.  It gets very hard
+	  when types come into the picture that have platform-dependent
+	  signedness, like "char" and "wint_t".  Adding yet another layer
+	  on top, changing both the signedness and the width in a platform-
+	  dependent way, makes auditing yet harder, which IMHO is really
+	  dangerous.  Note that while removing the #define, i already found
+	  one bug caused by this excessive complication - in the function
+	  re_putc() in refresh.c.  If WIDECHAR was defined, it printed an
+	  Int = wint_t value with %c.  Fortunately, that bug only affects
+	  debugging, not production.  The fix is contained in the patch.
+
+	  With WIDECHAR, this doesn't change anything.	For the case
+	  without WIDECHAR, i checked that none of the places wants to
+	  store values that might not fit in wint_t.
+
+	  This only changes internal interfaces; public ones remain
+	  unchanged.
+
+2016-02-14 15:47  christos
+
+	* chartype.c, chartype.h, read.c: From Ingo Schwartze:
+
+	  Next step:  Remove #ifdef'ing in read_char(), in the same style
+	  as we did for setlocale(3) in el.c.
+
+	  A few remarks are required to explain the choices made.
+
+	   * On first sight, handling mbrtowc(3) seems a bit less trivial
+	     than handling setlocale(3) because its prototype uses the data
+	     type mbstate_t from <wchar.h>.  However, it turns out that
+	     "histedit.h" already includes <wchar.h> unconditionally (i
+	  don't
+	     like headers including other headers, but that ship has
+	  sailed,
+	     people are by now certainly used to the fact that including
+	     "histedit.h" doesn't require including <wchar.h> before), and
+	     "histedit.h" is of course included all over the place.  So
+	  from
+	     that perspective, there is no problem with using mbrtowc(3)
+	     unconditionally ever for !WIDECHAR.
+
+	   * However, <wchar.h> also defines the mbrtowc(3) prototype,
+	     so we cannot just #define mbrtowc away, or including the
+	  header
+	     will break.  It would also be a bad idea to porovide a local
+	     implementation of mbrtowc() and hope that it overrides the one
+	     in libc.  Besides, the required prototype is subtly different:
+	     While mbrtowc(3) takes "wchar_t *" as its first argument, we
+	     need a function that takes "Char *".  So unfortunately, we
+	  have
+	     to keep a ct_mbrtowc #define, at least until we can maybe get
+	     rid of "Char *" in the more remote future.
+
+	   * After getting rid of the #else clause in read_char(), we can
+	     pull "return 1;" into the default: clause.  After that, we can
+	     get rid of the ugly "goto again_lastbyte;" and just "break;".
+	     As a bonus, that also gets rid of the ugly CONSTCOND.
+
+	   * While here, delete the unused ct_mbtowc() from chartype.h.

+
+	* read.c: From Ingo Schwarze:
+
+	  If CHARSET_IS_UTF8 is not set, read_char() is broken in a large
+	  number of ways:
+
+	   1. The isascii(3) check can yield false positives.  If a string
+	  in
+	      an arbitrary encoding contains a byte in the range 0..127,
+	      that does not at all imply that it forms a character all by
+	      itself, and even less that it represents the same character
+	      as in ASCII.  Consequently, read_char() may return characters
+	      the user never typed.
+	      Even if the encoding is not state dependent, the assumption
+	  that
+	      bytes in the range 0..127 represent ASCII characters is
+	  broken.
+	      Consider UTF-16, for example.
+
+	   2. The reverse problem can also occur.  In an arbitrary
+	  encoding,
+	      there is no guarantee that a character that can be
+	  represented
+	      by ASCII is represented by a seven-bit byte, and even less by
+	      the same byte as in ASCII.
+	      Even for single-byte encodings, these assumptions are broken.
+	      Consider the ISO 646 national variants, for example.
+	      Consequently, the current code is insufficient to keep ASCII
+	      characters working even for single-byte encodings.
+
+	   3. The condition "++cbp != 1" can never trigger (because
+	  initially,
+	      cbp is 0, and the code can only go back up via the final
+	  goto,
+	      which has another cbp = 0 right before it) and it has no
+	  effect
+	      (because cbp isn't used afterwards).
+
+	   4. bytes = ct_mbtowc(cp, cbuf, cbp) is broken.  If this returns
+	  -1,
+	      the code assumes that is can just call mbtowc(3) again for
+	  later
+	      input bytes.  In some implementations, that may even be
+	  broken
+	      for state-independent encodings, but trying again after
+	  mbtowc(3)
+	      failure certainly produces completely erratic and meaningless
+	      results in state-dependent encodings.
+
+	   5. The assignment "*cp = (Char)(unsigned char)cbuf[0]" is
+	      completely bogus.  Even if the byte cbuf[0] represents a
+	      character all by itself, which it usually will not, whether
+	      or not the cast produces the desired result depends on the
+	      internal representation of wchar_t in the C library, which
+	      the application program can know nothing about.  Even for
+	  ASCII
+	      in the C/POSIX locale, an ASCII character other than '\0' ==
+	      L'\0' == 0 need not have the same numeric value as a char and
+	      as a wchar_t.
+
+	  To summarize, this code only works if all of the following
+	  conditions hold:
+
+	   - The encoding is a single-byte encoding.
+	   - ASCII is a subset of the encoding.
+	   - The implementation of mbtowc(3) in the C library does not
+	     require re-initialization after encoding errors.
+	   - The implementation of wchar_t in the C library uses the
+	     same numerical values as ASCII.
+
+	  Otherwise, it silently produces wrong results.
+
+	  The simplest way to fix this is to just use the same code as for
+	  UTF-8 (right above).	Of course, that causes functional changes
+	  but that shouldn't matter since current behaviour is undefined.
+
+	  The patch below provides the following improvements:
+
+	   - It works for all stateless single-byte encodings, no matter
+	     whether they are somehow related to ASCII, no matter how
+	     mb[r]towc(3) are internally implemented, and no matter how
+	     wchar_t is internally represented.
+	   - Instead of producing unpredictable and definitely wrong
+	     results for non-UTF-8 multibyte characters, it behaves in
+	     a well-defined way: It aborts input processing, sets errno,
+	     and returns failure.
+	     Note that short of providing full support for arbitrary
+	  locales,
+	     it is impossible to do better.  We cannot know whether a given
+	     unsupported locale is state-dependent, and for a
+	  state-dependent
+	     locale, it makes no sense to retry parsing after an encoding
+	     error, so the best we can do is abort processing for *any*
+	     unsupported multi-byte character.
+	   - Note that single-byte characters in arbitrary
+	  state-independent
+	     locales still work, even in locales that may potentially also
+	     contain multibyte characters, as long as those don't occur in
+	     input.  I'm not sure whether any such locales exist in
+	  practice...
+
+	  Tested with UTF-8 and C/POSIX on OpenBSD.  Also tested that in
+	  the C/POSIX locale, non-ASCII bytes get through unmangled.  You
+	  may wish to test with ISO-LATIN on NetBSD if NetBSD supports
+	  that.

+
+2016-02-08 18:18  christos
+
+	* chartype.h, read.c: UTF-8 fixes from Ingo Schwarze:
+
+	   1. Assume that errno is non-zero when entering read_char()
+	      and that read(2) returns 0 (indicating end of file).
+	      Then, the code will clear errno before returning.
+	      (Obviously, the statement "errno = 0" is almost always
+	       a bug unless there is save_errno = errno right before it
+	       and the previous value is properly restored later,
+	       in all reachable code paths.)
+
+	   2. When encountering an invalid byte sequence, the code discards
+	      all following bytes until MB_LEN_MAX overflows; consider, for
+	      example, 0xc2 immediately followed by a few valid ASCII
+	  bytes.
+	      Three of those ASCII bytes will be discarded.
+
+	   3. On a POSIX system, EILSEQ will always be set after reading a
+	      valid (yes, valid, not invalid!) UTF-8 character.  The reason
+	      is that mbtowc(3) will first be called with a length limit
+	      (third argument) of 1, which will fail, return -1, and - on
+	      a POSIX system - set errno to EILSEQ.
+	      This third bug is mitigated a bit because i couldn't find any
+	      system that actually conforms to POSIX in this respect:  None
+	      of OpenBSD, NetBSD, FreeBSD, Solaris 11, and glibc set errno
+	      when an incomplete character is passed to mbtowc(3), even
+	  though
+	      that is required by POSIX.
+	      Anyway, that mbtowc(3) bug will be fixed at least in OpenBSD
+	      after release unlock, so it would be good to fix this bug in
+	      libedit before fixing the bug in mbtowc(3).
+
+	  How can these three bugs be fixed?
+
+	   1. As far as i understand it, the intention of the bogus errno =
+	  0
+	      is to undo the effects of failing system calls in el_wset(),
+	      sig_set(), and read__fixio() if the subsequent read(2)
+	  indicates
+	      end of file.  So, restoring errno has to be moved right after
+	      read__fixio().  Of course, neither 0 nor e is the right value
+	      to restore: 0 is wrong if errno happened to be set on entry,
+	  e
+	      would be wrong because if one read(2) fails but a second
+	  attempt
+	      succeeds after read__fixio(), errno should not be touched.
+	  So,
+	      the errno to be restored in this case has to be saved before
+	      calling read(2) for the first time.
+
+	   2. Solving the second issue requires distinguishing invalid and
+	      incomplete characters, but that is impossible with the
+	  function
+	      mbtowc(3) because it returns -1 in both cases and sets errno
+	      to EILSEQ in both cases (once properly implemented).
+
+	      It is vital that each input character is processed right
+	  away.
+	      It is not acceptable to wait for the next input character
+	  before
+	      processing the previous one because this is an interactive
+	      library, not a batch system.  Consequently, the only
+	  situation
+	      where it is acceptable to wait for the next byte without
+	  first
+	      processing the previous one(s) is when the previous one(s)
+	  form
+	      an incomplete sequence that can be continued to form a valid
+	      character.
+
+	      Consequently, short of reimplementing a full UTF-8 state
+	  machine
+	      by hand, the only correct way forward is to use mbrtowc(3).
+	      Even then, care is needed to always have the state object
+	      properly initialized before using it, and to not discard a
+	  valid
+	      ASCII or UTF-8 lead byte if it happens to follow an invalid
+	      sequence.
+
+	   3. Fortunately, solution 2. also solves issue 3. as a side
+	  effect,
+	      by no longer using mbtowc(3) in the first place.

+
+	* Makefile: Add new Makefile knob, USE_FORT, which extends USE_SSP
+	  by turning on the FORTIFY_SOURCE feature of libssp, thus checking
+	  the size of arguments to various string and memory copy and set
+	  functions (as well as a few system calls and other miscellany)
+	  where known at function entry.  RedHat has evidently built all
+	  "core system packages" with this option for some time.
+
+	  This option should be used at the top of Makefiles (or
+	  Makefile.inc where this is used for subdirectories) but after any
+	  setting of LIB.
+
+	  This is only useful for userland code, and cannot be used in libc
+	  or in any code which includes the libc internals, because it
+	  overrides certain libc functions with macros.  Some effort has
+	  been made to make USE_FORT=yes work correctly for a full-system
+	  build by having the bsd.sys.mk logic disable the feature where it
+	  should not be used (libc, libssp iteself, the kernel) but no
+	  attempt has been made to build the entire system with USE_FORT
+	  and doing so will doubtless expose numerous bugs and misfeatures.
+
+	  Adjust the system build so that all programs and libraries that
+	  are setuid, directly handle network data (including serial comm
+	  data), perform authentication, or appear likely to have (or have
+	  a history of having) data-driven bugs (e.g. file(1)) are built
+	  with USE_FORT=yes by default, with the exception of libc, which
+	  cannot use USE_FORT and thus uses only USE_SSP by default.
+	  Tested on i386 with no ill results; USE_FORT=no per-directory or
+	  in a system build will disable if desired.

+
+	* filecomplete.c, filecomplete.h, readline.c: Bug reported from
+	  Martin Dietze:
+
+	      The place to change the completion_append_character is
+	      usually somewhere in the `rl_completion_entry_function'
+	      callback which is where one usually can distinguish between
+	      file- or dir-like entries to append a slash for dirs etc.
+
+	      This does no longer work since `fn_complete()' takes the
+	      `append_character' as argument before the callback is
+	  executed,
+	      so that changes to the variable
+	  `rl_completion_append_character'
+	      have in fact no effect for the current completion.
+
+	  Fix by adding a function that returns the
+	  rl_completion_append_character, when it gets passed in a filename
+	  in readline emulation.

+	  wants the clean semantics    it must specifically append to
+	  CLEANFILES.	 Resolves PR toolchain/5204.
+
+	  * To recap: .d (depend) files are generated for all files in SRCS
+	  and DPSRCS   that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
+
+	  * If YHEADER is set, automatically add the .y->.h to DPSRCS &
+	  CLEANFILES
+
+	  * Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d	depend upon
+	  ${DPSRCS}
+
+	  * Deprecate the (short lived) DEPENDSRCS
+
+	  Update the various Makefiles to these new semantics; generally
+	  either adding to CLEANFILES (because DPSRCS doesn't do that
+	  anymore), or replacing specific .o dependencies with DPSRCS
+	  entries.
+
+	  Tested with "make -j 8 distribution" and "make distribution".

+	  missing several features, there were also minor errors in others.
+
+	  Compare netbsd sh to the definition available from:
+	  http://www.opengroup.org/onlinepubs/007904975/utilities/sh.html
+	  In particular the following were not supported:     U - undo all
+	  changes to line    | - goto column	     Y - yank to end of
+	  line	       y - yank        # - comment out current line    @ -
+	  take input from shell alias [1]     G - goto numbered line in
+	  history buffer	v - edit history line with vi	_ - append
+	  word from last input line    . - redo last command Other minor
+	  changes have also been made.
+
+	  [1] This needs the shell to define an appropriate routine to
+	  return the text of the alias.  There is no requirement that such
+	  a function exist.

+
+		  - USE_SHLIBDIR  If "yes", install shared libraries in
+	  ${SHLIBDIR}
+				  instead of ${LIBDIR}.  Defaults to "no".
+				  Sets ${_LIBSODIR} to the appropriate
+	  value.
+				  This may be set by individual Makefiles
+	  as well.
+
+		  - SHLINKDIR	  Location of shared linker.  Defaults to
+	  "/usr/libexec".
+				  If != "/usr/libexec", change the
+	  dynamic-linker
+				  encoded in shared programs
+
+	  * Set USE_SHLIBDIR for libraries used by /bin and /sbin:
+	  libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
+	  libtermcap libutil libz
+
+	  * If ${_LIBSODIR} != ${LIBDIR}, add symlinks from
+	  ${LIBDIR}/${LIB}.so*	 to ${_LIBSODIR}/${LIB}.so* for
+	  compatibility.
+
+	  * Always install /sbin/init statically (for now)
+
+	  The net effect of these changes depends on how the variables are
+	  set:
+
+	    1.)   If nothing is set or changed, there is no change from the
+		  current behaviour:
+			  - Static /bin, /sbin, and bits of /usr/*
+			  - Dynamic rest
+			  - Shared linker is /usr/libexec/ld*so
+
+	    2.)   If the following make variables are set:
+			  LDSTATIC=
+			  SHLINKDIR=/lib
+			  SHLIBDIR=/lib
+		  Then the behaviour becomes:
+			  - Dynamic tools
+			  - .so libraries used by /bin and /sbin are
+	  installed to /lib,
+			    with symlinks from /usr/lib/lib*so to ->
+	  /lib/lib*so
+			    where appropriate
+			  - Shared linker is /lib/ld*so
+
+	    3.)   As per 2.), but add the following variable:
+			  USE_SHLIBDIR=yes
+		  This forces all .so's to be instaleld in /lib (with
+	  compat
+		  symlinks), not just those tagged by their Makefiles to
+	  be.
+		  Again, compat symlinks are installed

+	  readline/readline.h: Standard location of readline headers is
+	  /usr/include/readline/, so install them there.  readline.h of
+	  libedit had to move to subdirectory 'readline', due to the way

+
+	  This addresses the completion part of lib/11581 by Richard
+	  Earnshaw.
+
+2000-11-28 23:37  jmc
+
+	* term.c: Alloc the keys structure with A_K_NKEYS as the multiplier
+	  rather than a hardcoded value of 4.
+
+	  A_K_NKEYS is currently 6 and this mismatch was stomping memory
+	  when initializing the keys. (specifically gdb lost the exec file

+
+2000-08-02 05:36  chuck
+
+	* el.c: make xxgdb and a gdb linked with libedit's readline
+	  emulation work properly together.   xxgdb communicates with a gdb
+	  running on a pty that it sets to -echo,-onlcr prior to forking
+	  the gdb process.  GNU readline preserves the -echo setting while
+	  libedit was undoing it (setting the tty to a sane state and
+	  totally confusing xxgdb's parser).
+
+	  this diff simply disables libedit if both readline emulation and
+	  "stty -echo" are used/set.   that is enough to make xxgdb work
+	  once again, but (XXX) this is not how GNU readline handles stty
+	  -echo (it does not echo anything, but editing commands like
+	  ^A,^K, etc.  still work), so the readline emulation isn't
+	  perfect.
+
+	  change reviewed by christos.

+	  XXX: due to an implementation issue, the rprompt has a 1 space
+	  gap before the      edge of the logical screen. editline's
+	  logical screen is 1 space less      than the full screen width,

+	  argv[0]. remove note in man page warning of former behaviour.
+
+1998-01-21 11:12  lukem
+
+	* read.c: fix compile errors if FIONREAD is defined.  noted by
+	  David Holland <dholland@bordeaux.eecs.harvard.edu> in [bin/4012].
+
+1998-01-05 08:41  perry
+
+	* shlib_version: RCSID Police.
+
+1997-12-20 20:15  christos
+
+	* el.c, el.h, read.c: Small optimization. Don't call isatty() on
+	  every invocation of el_gets, but remember if the tty setup
+	  failed... Also trim the input line of trailing \r's.
+
+1997-11-13 05:48  thorpej
+
+	* term.c, term.h: Un-"protect" term_beep() and rename it to
+	  __term_beep() to keep it out of the user's namespace.  We need to
+	  do this because the readline emulation functions call
+	  term_beep(), but readline isn't built using the same (funky)
+	  namespace-protection method as the rest of libedit (it's included
+	  like a normal library object).
+
+	  Without this (fairly disgusting) hack, any program linked against
+	  libedit will fail to link with an unresolved reference to
+	  term_beep() if using an Elf toolchain (e.g. on the Alpha).
+
+	  XXX Why this doesn't happen with NetBSD's a.out toolchain is a
+	  mystery XXX to me, and I'm not sure I really want to know (given
+	  that a.out XXX _should_ break the same way as Elf does in this
+	  case).
+
+1997-11-13 05:43  thorpej

+	* Makefile: Build readline.o into debugging versions of libedit,
+	  too.
+
+1997-11-12 22:56  thorpej
