matz 6212cfb9c5 * gc.c (Init_stack): stack region is far smaller than usual if
pthread is used.

* marshal.c (w_extended): singleton methods should not be checked
  when dumping via marshal_dump() or _dump(). [ruby-talk:85909]

* file.c (getcwdofdrv): avoid using getcwd() directly, use
  my_getcwd() instead.

* merged NeXT, OpenStep, Rhapsody ports patch from Eric Sunshine
  <sunshine@sunshineco.com>.  [ruby-core:01596]

* marshal.c (w_object): LINK check earlier than anything else,
  i.e. do not dump TYPE_IVAR for already dumped objects.
  (ruby-bugs PR#1220)

* eval.c (rb_eval): call "inherited" only when a new class is
  generated; not on reopening.

* eval.c (eval): prepend error position in evaluating string to

* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
  had become unbuildable; enhanced --enable-fat-binary option so that
  it accepts a list of desired architectures (rather than assuming a
  fixed list), or defaults to a platform-appropriate list if user does
  not provide an explicit list; made the default list of architectures
  for MAB (fat binary) more comprehensive; now uses -fno-common even
  when building the interpreter (in addition to using it for
  extensions), thus allowing the interpreter to be embedded into a
  plugin module of an external project (in addition to allowing
  embedding directly into an application); added checks for
  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
  ensures that -I/usr/local/include is employed when extensions'
  extconf.rb scripts invoke have_header() since extension checks on
  NextStep and OpenStep will fail without it if the desired resource
  resides in the /usr/local tree; fixed formatting of --help message.

* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
  (see configure's --enable-fat-binary option); added rule for new
  missing/getcwd.c.

* defines.h: fixed endian handling during MAB build (see configure's
  --enable-fat-binary option) to ensure that all portions of the
  project see the correct WORDS_BIGENDIAN value (some extension modules
  were getting the wrong endian setting); added missing constants
  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
  define in NeXT section.

* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
  NextStep since, on some installations, this value always resolves
  uselessly to zero.

* dln.c: added error reporting to NextStep extension loader since the
  previous behavior of failing silently was not useful; now ensures
  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
  on Rhapsody since this header lacks multiple-include protection,
  which resulted in "redefinition" compilation errors.

* main.c: also create hard reference to objc_msgSend() on NeXT
  platforms (in addition to Apple platforms).

* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
  makefiles so that extensions can be built MAB (see configure's
  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
  (but not cpp_command() because MAB flags are incompatible with
  direct invocation of `cpp').

* ext/curses/extconf.rb: now additionally checks for presence of these
  curses functions which are not present on NextStep or Openstep:
  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
  wscrl(), wsetscrreg()

* ext/curses/curses.c: added appropriate #ifdef's for additional set of
  curses functions now checked by extconf.rb; fixed curses_bkgd() and
  window_bkgd() to correctly return boolean result rather than numeric
  result; fixed window_getbkgd() to correctly signal an error by
  returning nil rather than -1.

* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
  pointers before invoking rb_tainted_str_new2() upon fields extracted
  from `struct passwd' and `struct group' since null pointers in some
  fields are common on NextStep/OpenStep (especially so for the
  `pw_comment' field) and rb_tainted_str_new2() throws an exception
  when it receives a null pointer.

* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
  platforms such as NextStep and OpenStep which lack strdup().

* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
  (char*) for older platforms such as NextStep and OpenStep.

* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
  platforms such as NextStep and OpenStep which lack strdup(); include
  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
  argument of gethostbyaddr() and getservbyname() from (const char*) to
  non-const (char*) for older platforms.

* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
  platforms such as NextStep and OpenStep which lack strdup().

pty extension version 0.3 by A.ito

1. Introduction

This extension module adds ruby a functionality to execute an 
arbitrary command through pseudo tty (pty).

2. Install

Follow the instruction below.

(1) Execute

      ruby extconf.rb

    then Makefile is generated.

(3) Do make; make install.

3. What you can do

This extension module defines a module named PTY, which contains
following module fungtions:

   getpty(command)
   spawn(command)

      This function reserves a pty, executes command over the pty 
      and returns an array. The return value is an array with three
      elements. The first element in the array is for reading and the 
      second for writing. The third element is the process ID of the
      child process. If this function is called with an iterator block,
      the array is passed to the block as block parameters, and the
      function itself returns nil.

      When the child process is suspended or finished, an exception is
      raised.  If this function is called with an iterator block,
      exception is raised only within the block.  Child process
      monitor is terminated on block exit.

   protect_signal
   reset_signal

      These functions are obsolete in this version of pty.
