Tue Oct  5 16:24:01 2004  Peter Naulls  <peter@chocky.org>

	* source/clib/swis.h, source/locale/iconv.c: Update to sync with
	  John-Mark Bell's changes.
	* source/clib/netdb.h: Further improve visibility of macros
	  for unsupported functions.
	* source/unix/unix.c: Improve comment.
	* Docs/ReadMe: Update iconv URL.

Fri Sep 24 00:09:00 2004  John Tytgat  <John.Tytgat@aaug.net>

	* objs/Makefile.in: Predefined _GNU_SOURCE as quick fix for Norcroft
	  users after the 12 Sept 2004 change in post.c.  Better fix would
	  probably be to make sure that UnixLib is compilable with and without
	  _GNU_SOURCE defined.
	* source/clib/sys/debug.h (__debug): Added comment what __debug is
	  doing.
	* source/clib/unixlib/sigstate.h (valid_address): constify its
	  parameters
	* source/signal/post.c (valid_address): Likewise.
	* source/clib/unixlib/unix.h: Minor comment updating.
	* source/scl/_koscli.s: Likewise.
	* source/pthread/_ints.s: Reverted the signed/unsigned compare change
	  from 7 Sep 2004 on request from Alex.
	* source/sound/dsp.c: Test result of first __os_cli("RMEnsure...
	  call too.
	* source/locale/iconv.c: Likewise; Added CVS/RCS keyword header.
	* source/signal/_signal.s (return_quickly/__h_cback_common): Removed
	  unnessary teq pc,pc test (partly revert from 7 Sep 2004 change).
	  Feedback from Alex.
	* source/sys/_longlong.s (_ll_ufrom_d, _ll_sfrom_d, _ll_ufrom_f,
	  _ll_sfrom_f): Added, based on a patch from Jeffrey Lee for
	  gccsdk/gcc/libgcc/lib1aof.s.
	* source/sys/debug.c (__debug): Avoid crash when __u is bogus; Print
	  the has_process value too.
	* source/sys/exec.c (execve): execve() after fork() still means that
	  there is a parent so has_parent may not be reset.  Also necessary
	  to correctly identify when dde_prefix needs to be set & used in
	  unix.c (__unixinit, _exit).
	* source/unix/unix.c (__unixinit, _exit): dde_prefix may only be updated
	  and used to reset process' CSD when the process isn't a child; Added
	  assert that has_parent is always set in a process struct found via
	  UnixLib$env; (_exit) Removed test based on has_parent/___vret because
	  we want both parent & child to exit via __exit() and not directly
	  via __vret (resumely legacy code).

	* source/clib/stat.h, source/unix/stat.c: Make stat/stat64
	  more like glibc to avoid problems with forward declarations.
	* source/signal/signal.c: Remove warning.

	  the DRender: filesystem.
	* source/clib/swis.h, source/clib/iconv.h, source/clib/iconv.c:
	  Interface to John-Mark Bell's iconv support module, instead
	  of requiring the large external iconv library.

	  of VMIN. 

Wed Sep  8 18:04:02 2004  John Tytgat  <John.Tytgat@aaug.net>

	* objs/.cvsignore: Added sound directory.
	* source/sys/_mem.s: Go back to v1.4 (i.e. before the Sep 7 2004 changes)
	  as there were, yet unidentified, problems with it.
	* source/sound/dsp.c (__dspopen): Enforce DigitalRenderer version 0.51.
	* source/sys/vfork.c: Include sys/debug.h instead of stdio.h when DEBUG

	* source/clib/unixlib/asm_dec.s: Moved chunk and error definitions from
	  source/module/sul.s to here as SharedUnixLibrary_SWIChunk and
	  SharedUnixLibrary_ErrorChunk; Formally defined the
	  SharedUnixLib_Error_* errors; Incorrect SWI error exit code was
	  generated with objasm; TABified.
	* source/clib/unixlib/sigstate.h: Aesthetic change; declared

	  writing; Ensuring SUL v1.02 instead of v1.00; Rename __cli ->
	  __uixlib_cli, __himem -> __image_rw_himem; a1 (on entry) of OS_Exit
	  must point to a filled in RISC OS error block; Define stack_corrupt_msg
	  and stack_corrupt conditionally; Calling __unixlib_fatal a 2nd time
	  results in panic calling OS_Exit; (stack_overflow_common) executing
	  signalhandler stack check *before* validity stack check otherwise you
	  get the wrong fatal error message.
	* source/sys/_vfork.s: Added comments.
	* source/sys/mman.c (__munmap_all): Updated comments.
	* source/sys/vfork.c: Minor cleanup.
	* source/unix/unix.c: Removed __unixlib_cli declaration; Be more

Sun Aug 03 18:34:24 1997 CL0027
Peter Burwood  <pjb@arcangel.dircon.co.uk>

	* clib/signal.h: Correct macros for sigaddset, sigdelset, sigismember
	and put them inside a __UNIXLIB_INTERNALS. These macros are not really
	for the user, especially since they do not do any argument checking.

	* clib/stdlib.h: Declare setenv, unsetenv and clearenv.

	* clib/sys/unix.h: Add envp and envb to Unix proc struct. These are
	temporary until the UnixLibSupport module is ready. They are used to
	pass the current environ to a child process. Remove declaration of
	defunct __permstr. Declare __decstrtoui, __last_environ,
	__UNIX_ENV_PREFIX and environment support functions.

	* stdio/popen.c: (pclose): Return status from wait not return value of
	wait. Do not close stream->fd directly in pclose, let fclose do it.

	* sys/exec.c: (execve): Copy current environ into proc struct for
	child process to collect. Check result of realloc before storing so
	memory leak is avoided. Reorganisation to move calculation of
	__codeshift and __exshift later in function so that malloc_trim can
	be called safely. Fix store beyond end of buffer when argv[0] is NULL,
	i.e., when called from system with execl (line, 0).

	* sys/syslib.c: (_exit): Do not set Sys$ReturnCode since __exit does it.

	* sys/vfork.c: Initialisation and freeing of child's envp and envb.
	Use monotonic clock to generate process id (this will change).

	* unix/chdir.c: Rewritten to use and change Prefix$Dir when it has
	been set. Use new __getenv_from_os.

	* unix/getcwd.c: Complete rewrite to reduce code size and make clearer.
	Check Prefix$Dir first since OS_File calls are intercepted by DDEUtils.
	Use new __getenv_from_os. Remove possible memory errors.

	* unix/getenv.c: Complete rewrite. Use __UNIX_ENV_PREFIX when
	environment names interact with global RISC OS environment. Support
	for new setenv, clearenv and unsetenv functions. Remove need for static
	__envcnt and __envsize variables. __intenv now only checks RISC OS
	environment. Allow for environ to have been allocated in parent process.

	* unix/pipe.c: Change call to __intenv and __permstr.

	* unix/putenv.c: Rewritten to not modify argument and allow NAME to be
	removed from the environment. Use setenv to add and unsetenv to remove.

	* unix/setenv.c: New file to provide setenv, unsetenv and clearenv.

	* unix/unix.c: Add default value for UnixFS$/pipe to use Wimp$ScrapDir,
	needed for cases when programs use pipes but do not set UnixFS$/pipe.
	Remove __permstr and use strdup instead. Make __decstrtoui external
	and check END argument before writing to it. Collect environment from
	parent process if we are a child. Use monotonic clock to generate
	process id (this will change).

Sun Aug 03 15:45:24 1997 CL0025

Peter Burwood  <pjb@arcangel.dircon.co.uk>

	* clib/unixlib/local.h: Arguments to __address_valid are now const.

	* locale/localeconv.c: (read_byte_list): Converted sprintf call into
	inline code and check buffer does not overflow.

	* unix/uname.c: Extract module version from help string instead of
	using OS_Module 20 since that does not work on ROMPatches which is
	not a ROM module.

	* clib/string.h: Removed #ifdef 0 from strxfrm and strcol
	
	* locale/setlocale.c: setlocale(,"") equivalent to setlocale(,"C").
	  comment in perl source:

	  variables from which to get a locale name.
	
	  implication: most Unixes accept "" without complaint.
	
	* clib/unixlib/local.h: __attribute to __attrib

	* common/fdname.c: New file for __fd_to_name.

	* common/serial.c: Modified __get_file_ino so __uname is only performed
	when DIRECTORY is not NULL (as called from readdir). Fixed DIRECTORY
	and NAME concatenation to not overrun the internal buffer.

	* sys/debug.c: Only print active file descriptor and now print the
	filename corresponding to them.

	* unix/chmod.c: Return EPERM on protection change error rather than
	RISC OS error. Use __fd_to_name in fchmod. Return more Unix errors
	where appropriate when RISC OS error occurs.

	* unix/dev.c: (__fsopen): Open the file before setting protection
	bits on a newly created file. This allows RCS lock files to be
	created open for writing with permission 444 (r--r--r--).
	(__fsclose): Use __fd_to_name.

	* unix/dirent.c: New readdir_r function for POSIX. readdir function
	now reentrant for different DIR streams by using a buffer allocated
	on demand in the DIR stream and uses readdir_r function.

	* unix/stat.c: (fstat): Use __fd_to_name. Return more Unix errors
	where appropriate when RISC OS error occurs.
