	Merge pull request #239 from jimmyharris/fix-termios
	Preserve baud rates in termios table

2015-11-20  James Harris  <james.harris@garmin.com>

	Preserve baud rates in termios table
	Previous versions of the termios interface assumed that the baud rate
	constants B0 B50 ... B115200 were bit masks that needed to be set in the
	cflags member of the termios struct. On most modern operating systems
	those are actually mapped to different members (not usually documented)
	that contain the baud speed. This speed is set using the posix
	functions: cfgetispeed(), cfgetospeed(), cfsetispeed(), and
	cfsetospeed(). Because the termios_p struct is translated into a lua
	table rather than being maintained in its original data format, extra
	information like the baud rate is lost.  This doesn't effect
	manipulations on ptty devices, but attempting to use this functionality
	over a physical serial connection results in the baud rate being set to
	whatever value was in the termios_p when it was created.

	This patch fixes this issue by adding the ispeed and ospeed to the lua
	representation of termios_p. This will allow luaposix to properly handle
	serial files backed by physical pipes.

	signal: workaround a printf long vs int type coercion issue.
	* ext/posix/signal.c (sig_handle): Some architectures use a long
	for sig_atomic_t, so we need a %ld specifier to display it without

	up before passing to fprintf.

	sys.socket: move sys/types.h include earlier.
	* ext/posix/sys/socket.c: netinet/udp.h complains about lack of
	u_short definition on FreeBSD 10, so move sys/types.h before it
	in the hope of fixing that.
	Reported by jeangit@github.

	sys.resource: add ifdef guards to RLIM_SAVED_CUR and RLIM_SAVED_MAX.
	* ext/posix/sys/resource.c (luaopen_posix_sys_resource): Add

	On OpenBSD 5.6, _POSIX_VERSION is set to just 199009L by default,
	and messing with _XOPEN_SOURCE or setting _POSIX_VERSION directly
	changes the C library header declarations.  It seems that

	* configure.ac (POSIX_EXTRA_CPPFLAGS): Elide _XOPEN_SOURCE
	definition on OpenBSD.

	guards, as these two are not defined on at least OpenBSD 5.6.

	configury: propagate _XOPEN_SOURCE cpp defines fully.
	* configure.ac (POSIX_EXTRA_CFLAGS): A misnomer...
	(POSIX_EXTRA_CPPFLAGS): ...better named like this.

	preprocessor definitions reach submodule compilation too.

	headers when checking for net/if.h and linux/netlink.h.

	(luaL_register): Lua 5.2 and 5.3 compatibility definitions.
	* ext/posix/sched.c, ext/posix/termio.c: Use luaposix optint()
	rather than deprecated luaL_optint().
	* NEWS: Update.

	bit32: remove remaining `require "bit"` invocations.
	* lib/posix.lua.in: require "posix.bit32" unconditionally.
	* specs/posix_unistd_spec.yaml: Likewise.

	posix: improve portability of constant definitions.
	Rather than try to catalog what compiler/OS releases supply what
	constant symbols in their headers with a rats nest of `#if __BSD`
	etc, wrap all of the contentious preprocessor defines in matching
	`#ifdefs` so that they are only provided by luaposix in the
	environments that define them.  This should provide much better
	future portability to new compiler/OS combinations.
	* lposix.c (lua_open_posix_c): Simplify the declarations by using
	a consistent MENTRY definition.
	Except for extremely well-known groups of symbols, and groups
	that are already inside _POSIX_VERSION >= 200112L guards, wrap
	each constant declaration in a matching `#ifdef`.

	The '5.1.' prefix is a misnomer now tha we support Lua 5.2, and

2013-04-23  Ico Doornekamp  <ico@pruts.nl>

	Fixed dir example for 5.2

	Added missing 57k6 baudrate to termios table

2013-04-17  Ico Doornekamp  <ico@pruts.nl>

	Fixed glob example, added missing 'posix ='. Also removed the readlink() part because /proc on linux violates posix and does not properly fill in st_size on lstat(), causing readlink() to fail with EINVAL.

	Fix poll example, open failed due to wrong 2nd argument type, probably from old lposix API?

	I broke poll with commit 8deb0ebd041ab6d4761f86a7a906dd850111bae7
	The result is just fine for calling poll() only once, but breaks for
	subsequent calls to poll() when passing the same table. In this case,
	the events are not cleared from the revents table, causing false
	positives.

	tests-posix.lua: fix pipeline test for VPATH build

	tests-posix.lua: fix pipeline test
	Should call pipeline_slurp, not pipeline_iterator to get whole output
	in one go. This has the nice side-effect of testing both
	pipeline_iterator and pipeline as well, as pipeline_slurp calls
	pipeline_iterator, which calls pipeline.

	posix.lua: rename posix.system to posix.spawn, keeping old name as alias for now.

2013-03-16  Reuben Thomas  <rrt@sc3d.org>

	Allow posix.system to take a function, a shell command, or a file and list of arguments. Use it in pipeline.
	Allow pipeline functions to take an extra parameter giving the
	function to use to make a pipe (e.g. so posix.openpty can be used
	instead). Change argument to a table rather than a list of tasks.

2013-03-14  Reuben Thomas  <rrt@sc3d.org>

	* bootstrap.conf (gnulib_tool_options): Add --avoid=dummy to skip
	the one remaining empty gnulib C source file.
	(luaposix_remove_empty_lib): gnulib-tool now generates a useless
	lib subdirectory containing just a Makefile.am and .gitignore. We
	don't use or need it any more, so delete it.
	(luaposix_finish): Don't copy dummy.c out of gnulib.

2013-01-10  Gary V. Vaughan  <gary@gnu.org>

	curses: conditional resizeterm support.
	* configure.ac (AC_CHECK_FUNCS): Check whether resizeterm is
	implemented by the selected curses library.
	* lcurses.c (Cresizeterm): If it is, use it, otherwis throw an
	error to explain why not.
	(curseslib): Add it to the toplevel curses functions.

	curses: don't waddstr() each string twice.
	Fix a bug introduced by commit 5aa297512.
	* lcurses.c (Waddstr): Only add the string one time!

	configury: no need to fork for libtool.m4 variables.
	libtool.m4 is expanded into configure already, so the values are
	available after LT_INIT in configure.in without creating config.lt
	to copy the values we already have into an early libtool script,
	and then fork again to grep the content of those copies back into
	configure!!  (LT_OUTPUT is only necessary if you need to run
	configure time compilation tests using the libtool script to
	wrap the actual compiler).
	* configure.ac (LT_OUTPUT): Remove.
	(shrext): shrext_cmds is already set by LT_INIT, so just use it
	without calling the early libtool script.

	configury: remove automake -Werror option.
	This option causes automake to bail out after warning about the
	use of gmake extensions.
	* configure.ac (AM_INIT_AUTOMAKE): Remove -Werror.

	bootstrap: sync with upstream.
	This revision fixes some small bugs, and is compatible with
	non-gnu awk and non-gnu sed again.
	* bootstrap: sync with upstream.

	configury: keep gnulib revision under version control.
	It's important to keep the gnulib revision number used by any
	particular checkout of luaposix under version control rather than
	hoping that whatever the current HEAD is will work.
	* .gitignore: Remove gnulib.
	* gnulib: Add current master revision.

	configury: use AM_PROG_AR for automake 1.13.
	* configure.ac (AM_PROG_AR): Required by recent automake releases,
	but not available in very old releases.

	(R): List Pstatvfs if we wrapped it earlier.

	crypt: this function is available on darwin, but no crypt.h header is
	One of the main principles of Autoconf is that you should test for
	features, not for versions - exactly because of compilation problems
	like this, where Apple sets _POSIX_VERSION to make us think that
	crypt.h is available, but there is no crypt.h header.
	* configure.ac (crypt.h): Test for presence of this header.
	(crypt): If the crypt function is available, whether or not the
	additional -lcrypt library is required, define HAVE_CRYPT.
	* lposix.c (crypt.h): Include it if configure found it.
	(Pcrypt): Define it if configure detected a system crypt API.

2011-12-26  Gary V. Vaughan  <gary@gnu.org>

	curses: expose use_default_colors to lua.
	* lcurses.c (Cuse_default_colors): Marshalling for
	use_default_colors.
	(curseslib): Add it.

	refactor: use lposix-style macro splicing in lcurses.
	Make the style of lcurses.c more like lposix.c, with the aid of
	splice and stringify macros, and judicious renaming to make
	their usage pattern the same too.
	* lcurses.c (LCURSES_SPLICE, LCURSES_STR, LCURSES_STR_1):
	Analagous to LPOSIX_SPLICE, LPOSIX_STR and LPOSIX_STR_1
	respectively.
	(LC_NUMBER, LC_NUMBER2, LC_STRING, LC_STRING2, LC_BOOL)
	(LC_BOOL2, LC_BOOLOK, LC_BOOLOK2): Change prefix of generated
	functions from `lc_' to `C' so that LCURSES_STR_1 can be used
	idiomatically.
	(LCW_BOOLOK): Likewise, only changing from `lcw_' to `W' prefix.
	(LCW_BOOLOK2): New macre used when the curses symbol and the lua
	api have different names.
	(lcw_new, lcw_get, lcw_check, lc_checkch, lc_optch): Rename from
	these...
	(lc_newwin, lc_getwin, lc_checkwin, checkch, optch): ...to
	these, respectively, no need to namespace static symbols so
	carefully. Adjust all callers.
	(CC2): Remove.
	(CF): New macro for generating FN key exports into lua. Use it
	to export all 64 valid FN keys.
	(LCW_WIN2): New macro.
	(Wsyncup, Wcursyncup, Wsyncdown): Use it to define these
	functions.
	(LCW_WIN2YX): New macro.

	(Wattroff, Wattron, Wattrset): Use it to define these functions.

	This would have prevented the recent unsynced signal tables bug,

	that needs to stay in sync between various strings and symbols.
	* lposix.c (LPOSIX__STR): Remove +1 offset.
	(LPOSIX__STR_1, LPOSIX_STR_1): Better name for +1 offset
	stringification macros. Adjust all callers.

	Add full poll(2) interface

2011-10-22  Nikolai Kondrashov  <nkondrashov@nvidia.com>

	Add full poll(2) interface
	Rename Ppoll to Prpoll to match external name of "rpoll".
	Add full poll(2) interface under name "poll".

	The arguments to the "poll" function are fd->pollfd map and an optional
	timeout in milliseconds (default being -1, i.e. infinity).

	"Pollfd" is a table analogue of struct pollfd, with "event" and "revent"
	fields being tables with boolean fields corresponding to bits, named without
	"POLL" suffix.

	Example usage:

	local pollfd_map = {
	    [fd1]   = {events = {IN = true}},
	    [fd2]   = {events = {IN = true}},
	    [fd3]   = {events = {IN = true}}
	}

	while next(pollfd_map) ~= nil do
	    local ready, errmsg = posix.poll(pollfd_map)

	    if ready == nil then
	        error(errmsg)
	    end

	    for fd, pollfd in pairs(polfd_map) do
	        if pollfd.revents.IN or pollfd.revents.HUP then
	            local input, errmsg, errno = posix.read(fd, 8)

	            if input == nil then
	                error(errmsg)
	            elseif #input == 0 then
	                pollfd_map[fd] = nil
	            else
	                print(tostring(fd) .. ":", input:byte(1, -1))
	            end
	        end
	    end
	end

	Don't leave status uninitialized
	SUSv4 states that &status is undefined if WNOHANG option is passed to
	waitpid and no processes are ready to be collected at the time of call.

2011-10-10  Alexander V. Nikolaev  <avn@daemon.hole.ru>

	Fix bug -- posix.read returns wrong value
	Pread() is documented to return a single value, and pushed only one
	return value to stack, but it told Lua that it returns two values.

	Note that this change may existing workarounds and should be
	explicitly mentioned in release notes.

2011-10-10  Reuben Thomas  <rrt@sc3d.org>

	  require support for struct flock).

	configury: add libcrypt if required
	When the crypt() function does not work unaided, try again by adding
	libcrypt to LIBS and substituting into Makefile.in.

	portability: darwin has no O_RSYNC definition

	configury: need dummy module incase gnulib has no other objects
	It's only safe to use --avoid=dummy when there will never be a libgnu.a
	built, i.e there are no other modules with C code, and thus the parent
	project is never linked with libgnu.

2011-09-08  Gary V. Vaughan  <gary@vaughan.pe>

	configury: let bootstrap.conf manage gnulib .gitignore
	No need to check these files in when bootstrap.conf has functions to

	For this changeset to work properly, you'll need to `git clean -f -x -d`
	and then rerun bootstrap to generate a proper set of .gitignore files.

	Fixed bugs in dup().
	 * Fixed bug: segfault (null pointer dereference) in dup(x,nil).

	 * Fixed bug: non-conforming mode "rw" changed to "w+".  POSIX specifies "w+" or
	   "r+" for read/write open.  "rw" is incorrect and fails to open for writing
	   on GNU libc's fdopen().

2011-05-11  David Favro  <lua@meta-dynamic.com>

	Updated test.lua and added new tests.
	 * Removed deprecated constructs foreach(), getn().

	set/getrlimit, set/getuid and setlogmask bindings
	Hi,

	  while packagin the jabber server "prosody" for Debian, I noticed that
	it was using a custom binding of some posix function not available in
	luaposix. After asking prosody author, I wrote a patch for luaposix
	that adds the missing functionalities prosody is actually shipping in a
	custom .so.

	The attached patch binds the following functions:
	set/getrlimit, set/getuid and setlogmask.

	I'd like it to be integrated in a future release of luaposix, if
	posible.

	Cheers
