2020-01-16  Juan M. Guerrero  <juan.guerrero@gmx.de>


	* basicdefs.h [__DJGPP__]: New macro initialize_main.  Copies argv[0]
	into __djgpp_program_invocation_name[FILENAME_MAX] that is used by
	getprogname.

	* doc/sed.tex: Add DJGPP port specific info about backup names when
	only SFN supports is available.

	* gnulib-tests/init.sh (remove_tmp_): For DJGPP ignore generated error
	status by internal operations.  They would erroneously set the check
	to failed.

	* lib/acl-errno-valid.c: A default value for EOPNOTSUPP added.

	* lib/copy-acl.c [__DJGPP__]: Include fcntl.h for _USE_LFN definition.
	(copy_acl) [__DJGPP__]:  If only SFN is available fchmod will fail with
	ENOSYS whhen trying to change the file mode.  In this case do not issue
	the error message.

	* lib/fwriting.c [__DJGPP__]: Support fwriting function.

	* lib/getdelim.c (getdelim) [MSDOS]: For DOS-like systems strip the
	trailing CR.

	* lib/getprogname.c (getprogname) [__DJGPP__]:  Implementation of
	DJGPP support.

	* lib/stdio-impl.h [__DJGPP__]: Include sys/file.h to provide _IOWRT
	for fwriting function support.

	* lib/tempname.c: New macro HAVE_DIFFERENT_TMPDIR.  Value depends
	on if the OS is posix or not.
	(direxists): Use ISSLASH to check for the OS dependent directory
	separator character.  Use HAVE_DIFFERENT_TMPDIR to check for TMP
	and TEMP too, if none of them are defined or do not point to an
	existing directory default to the current directory.

	* sed/execute.c	(dump_append_queue): Call set_read_mode.
	(dump_append_queue) [O_BINARY]: Remove ^M, if before the newline, and
	^Z, if immediately before EOF.
	(get_backup_file_name) [MSDOS, __DJGPP__]: Use LFN_FILE_SYSTEM to check
	if only SFN support is available.  In that case generate a new and 8+3
	conforming backup file name.
	(open_next_file): Call set_read_mode.  Use LAST_SLASH.
	(closedown): Close files to be renamed before issuing the rename() and
	not after.

	* sed/sed.c (main) [SYSTEM_CALL_NEED_MULTIPLE_CMDS_ENABLING]: Set
	system_allow_multiple_cmds in the system_flags variable.
	(main): Strip extension from argv[0].
	[O_BINARY]: G_file_descriptor_of_file_to_unlink stores the file
	descriptor of temporary file to be deleted.
	[O_BINARY]: New function register_cleanup_file_descriptor to
	register the file descriptor of the temporary file.
	(cleanup): Use CLOSE_FILE_TO_UNLINK to close temporary file before
	unlinking it.

	* sed/utils.c [O_BINARY]: Include sys/stat.h and make sure S_ISCHR
	is defined.
	(set_read_mode): New function, switches a stream into binary mode.
	This is a no-op unless O_BINARY is defined.
	(ck_mkstemp) [MSDOS]: Check for the TEMP variable too before defaulting
	to P_tmpdir and test that the used tempdir really does exists before
	starting using it.
        (is_a_device): New function, checks if the file pointer is associated
        to stdout.
	(ck_fwrite) [O_BINARY]: If we are writing to a character device,
	replace every ^Z character with an ASCII string "^Z".
	(follow_symlink): Use IS_SLASH and LAST_SLASH to detect directory
	separator character in the file name.
	(ck_mkstemp) [O_BINARY]: Call register_cleanup_file_descriptor to
	store the file descriptor of the temporary file.

	* sed/utils.h: Include fcntl.h.
	[_O_BINARY]: Define O_BINARY and setmode if not undefined.
	[O_BINARY]: Include io.h.
	[O_BINARY, __DJGPP__]: New macro STRIP_FULL_PATH_AND_EXTENSION
	STRIP_EXTENSION, CANONICALIZE_PATH.  No-op for other
	operation systems.
	[O_BINARY, __DJGPP__]: New macro SYSTEM_CALL_NEED_MULTIPLE_CMDS_ENABLING
	to signal on non POSIX systems where for system() multiple, semicolon
	separated, commands must be explicitly enabled.
	[O_BINARY, __DJGPP__]: Declare the system_flags variable to change
	system() behaviour.
	[O_BINARY, __DJGPP__]: New macro IS_TMPDIR to check that the value
	passed really points to an existing directory to be used as tmpdir.
	For no DJGPP system it defaults to the original sed code check.
	[O_BINARY, __DJGPP__]: New macro IS_SLASH to check if character is a
	directory separator for the particular OS.
	[O_BINARY, __DJGPP__]: New macro initialize_main.  Copies argv[0] into
	__djgpp_program_invocation_name[FILENAME_MAX] that is used by
	getprogname.
	[O_BINARY]: New macro LAST_SLASH defined to check for the last slash or
	backslash as directory separator in the given filename.
	[O_BINARY]: New macro LFN_FILE_SYSTEM to check if the used file system
	supports LFN or only SFN.
	[O_BINARY]: New macro CLOSE_FILE_TO_UNLINK that closes the temporary
	file before unlinking it.  Is a no-op for all other OSs.
	Declare a prototype of set_read_mode.

	* testsuite/in-place-suffix-backup.sh: Adjust error message to DJGPP style.

	* testsuite/compile-errors.sh: Escape \r so that it works on DOS.

	* testsuite/convert-number.sh: Escape \0 so that it works on DOS.

	* testsuite/nulldata.sh: Escape EOL symbols so that it works on DOS.

	* testsuite/temp-file-cleanup.sh: Remove any potentialy existing DJGPP
	specific files from list of allowed and existing files in the directory.

 If no extension is supplied, the original file is
 overwritten without making a backup.
 
+For the @acronym{DJGPP} port, if only SFN support is available,
+the backup file name will be truncated to the well known @code{8+3}
+length.  This rule is followed: the suffix will remove as many
+characters as necessary from a potentially existing extension to
+fit into the 3 characters long space available for extensions;
+if a prefix is given, it will shift to the right as many as
+characters are necessary to fit into the 8 characters long space
+available for file names.  As example, the following command:
+
+@example
+sed -ibck_*_up s/foobar/raboof/ filename.txt
+@end example
+
+@noindent
+will produce a backup file for @code{filename.txt} with @code{bck_file._up}
+as backup file name.  As can be seen the suffix @code{_up} is 3
+characters long an overwrites the file name's extension @code{ext}
+completely.  The prefix @code{bck_} is 4 characters long and occupies
+the place of the first 4 characters of the file name, so that the last
+4 characters of the original file name are lost.
+
 Because @option{-i} takes an optional argument, it should
 not be followed by other short options:
