unix 下tar 执行程序的源代码

	* tar.c (name_add) Use sizeof(char *) instead of sizeof(int)

	* README give the correct return address.

Thu Oct 25 16:03:58 EDT 1990	Jay Fenlason ([e-mail])

	rtape_lib.c	Change RMTIOCTL to NO_RMTIOCTL, so it is on by default.

	rmt.h		Add _isrmt() #define for NO_REMOTE case.

	gnu.c		Add forward reference for add_dir_name().

Tue Oct 16 11:04:52 EDT 1990	Jay Fenlason ([e-mail])

	1.09	New -G file implementation of gnu-dump stuff.

	* tar.c  (name_add)  Get the calls to ck_realloc and ck_malloc right.

Thu Oct 11 11:23:38 EDT 1990	Jay Fenlason ([e-mail])

	* gnu.c  Fix A couple of typos.

Wed Sep 19 13:35:03 1990  David J. MacKenzie  (djm at apple-gunkies)

	* getdate.y [USG] (ftime): Use `daylight' unless
	DAYLIGHT_MISSING is defined.

Mon Sep 17 18:04:21 EDT 1990	Jay Fenlason ([e-mail])

	* gnu.c (gnu_restore)  Don't use a passed char* for the
	file name, use skipcrud+head->header.name, just like everything
	else does.  This means that gnu_restore will still work with
	small buffers, etc.

Thu Sep 13 15:01:17 EDT 1990	Jay Fenlason ([e-mail])

	* tar.c (add_exclude)  Don't bus-error if the exclude file doesn't
	end with a newline.

Sun Sep  9 22:35:27 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* Makefile (dist): Remove .fname when done.

Thu Sep  6 12:48:58 EDT 1990	Jay Fenlason ([e-mail])

	* gnu.c (gnu_restore) Rember to skip_file() over the directory
	contents, even if we don't have to do anything with them.

	* create.c extract.c diffarch.c  Free sparsearray after we're done
	with it.

Tue Sep  4 10:18:50 EDT 1990	Jay Fenlason ([e-mail])

	* Makefile  Include gnu.c in dist

	* gnu.c move add_dir above read_dir_file so that cc doesn't complain
	about add_dir returning void.

Sun Sep  2 20:46:34 1990  David J. MacKenzie  (djm at apple-gunkies)

	* getdate.y: Declare some more functions and add storage
	classes where omitted to shut compiler up.
	[USG] (ftime): Don't use extern var `daylight'; appears that
	some systems don't have it.

Wed Aug 29 00:05:06 1990  David J. MacKenzie  (djm at apple-gunkies)

	* getdate.y (lookup): In the code that allows `Aug.' to be
	recognized as `Aug', don't chop off the final `.' from words
	like `a.m.', so they can be recognized.

Thu Aug 16 11:34:07 EDT 1990	Jay Fenlason ([e-mail])

	* buffer.c (open_archive)  If -O, write verbosity to stderr
	instead of stdout.

Fri Aug 10 12:29:28 EDT 1990	Jay Fenlason ([e-mail])

	* getdate.y  Handle an explicit DST in the input string.
	A dozen line patch from Per Foreby ([e-mail]).

Mon Jul 16 13:05:11 EDT 1990	Jay Fenlason ([e-mail])

	* tar.c  rename -g -G +incremental, +listed-imcremental, etc.

Fri Jul 13 14:10:33 EDT 1990	Jay Fenlason ([e-mail])

	* tar.c  Make +newer and +newer-mtime work according to their names.

	* gnu.c  If +newer or +newer-mtime, use the time specified on the
	command line.

	* buffer.c, create.c  Add test to see if dimwit is trying to
	archive the archive.

	* tar.c  (long_options[]) re-ordered, so that groups of similar
	options are next to each other. . .  I think.

		(describe)  Modified to more closely reflect reality.

Fri Jul  6 13:13:59 EDT 1990	Jay Fenlason ([e-mail])

	* tar.c  add compile-time option for SYS V (?) style
	tape-drive names /dev/rmt/{n}[lmh]

	* tar.c  Fix getopt-style stuff so that -C always works correctly.

	* gnu.c, tar.c make filename to -G optional.

	* {all over}, replace some fprintf(stderr...) calls with calls
	to msg().

	* port.c  Make -Dmumble_MSG option on command line override
	internal assumptions.

	* Makefile  Mention -Dmumble_MSG options

Fri Jul  6 02:35:31 1990  David J. MacKenzie  (djm at apple-gunkies)

	* tar.c (options): Don't change `c' if it is 0, as getopt now
	handles that internally.

Mon Jul  2 15:21:13 EDT 1990 Jay Fenlason ([e-mail])

	* gnu.c  (new file)  Moved all the f_gnudump stuff here where we
	can keep track of it easier.  Also made -G take a file name where it
	stores the inode information about directories so that we can
	detect moved directores.

	* create.c (dump_file)  Changed slightly to work with the new
	f_gnudump.

	* tar.c  Moved the f_gnudump stuff to gnu.c

	* tar.c, extract.c  added the +do-chown option, which forces tar
	to always try to chown the created files to their original owners.

	* version.c  New version 1.09

Sun Jun 24 14:26:28 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* create.c: Change ifdefs for directory library header
	selection to be like the ones in tar.c.
	* Makefile [Xenix]: Link with -ldir to get the dirent.h
	directory library.

Thu Jun  7 03:31:51 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* Makefile, buffer.c, diffarch.c: Change MTIO symbol to HAVE_MTIO
	because SCO Xenix defines 'MTIO' for an incompatible tape driver
	system in a file included by termio.h.
	* tar.h: Don't define size_t for Xenix.

Tue Jun  5 11:38:00 EDT 1990 Jay Fenlason ([e-mail])

	* create.c (dump_file)  Only print the
	"... is on a different filesystem..." if f_verbose is on.
	also add a case for S_IFSOCK and treat it like a FIFO.
	(Not sure if that's the right thing to do or not, but it's better
	than all those Unknown File Type msgs.)

Thu May 31 19:25:36 EDT 1990 Jay Fenlason ([e-mail])

	* port.c  Use #ifdef sparc instead of #ifdef SPARC since
	the lowercase version is defined, and the uppercase one isn't.

Tue May 22 11:49:18 EDT 1990 Jay Fenlason ([e-mail])

	* port.c (ck_malloc)  if size==0 pretend size=1
		(ck_realloc)  if(!ptr) call ck_malloc instead.

Tue May 15 12:05:45 EDT 1990 Jay Fenlason ([e-mail])

	* diffarch.c (diff_archive)  If not f_absolute_paths, and attempt to
	open a file listed in the archive fails, try /filename also.  This will
	allow diff to open the wrong file if both /filename and filename exist,
	but there's nothing we can do about that.

Fri May 11 16:17:43 EDT 1990 Jay Fenlason ([e-mail])

	* Makefile, Descripbe new -DMTIO option.

	* buffer.c diffarch.c  Change ifdefs slightly, so that
	-DMTIO will include sys/mtio.h even if USG is defined.
	This is for HUPX and similar BSD/USG crossovers.

Tue May  8 13:14:54 EDT 1990 Jay Fenlason ([e-mail])
	* update.c (update_archive)  Call reset_eof() when appropriate.

	* buffer.c (reset_eof)  New function, that turns of EOF flag, and
	re-sets the ar_record and ar_last pointers.  This will allow
	'tar rf non-existant-file' to not core-dump.

Fri May  4 14:05:31 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* tar.c: Recognize the +sparse option.  It was documented, but
	only the short form (-S) was actually recognized.

Tue Apr 17 21:34:14 EDT 1990 Jay Fenlason ([e-mail])

	* create.c  Don't access location 0 if ->dir_contents is null.

Wed Apr 11 17:30:03 EDT 1990 Jay Fenlason ([e-mail])

	* buffer.c (flush_archive, close_archive, new_volume) Always check
	the return value of rmtclose(), and only give a warning msg if it is
	<0.  Some device drivers (including Sun floppy disk, and HP
	streaming tape) return -1 after an IO error (or something like that.)

Fri Mar 23 00:06:30 1990  Jim Kingdon  (kingdon at mole.ai.mit.edu)

	* tar.c (long_options): Make it so +append +extract +list +update
	+catenate and +delete don't take arguments.

Mon Mar 12 13:33:53 EST 1990

	* buffer.c (open_archive, fl_write) Set the mtime of the volume
	header to the current time.

Wed Mar  7 14:10:10 EST 1990	Jay Fenlason ([e-mail])

	* buffer.c  Fix +compress-block  A two character patch from
	Juha Sarlin ([e-mail])
		Replace #ifdef __GNU__ with #ifdef __STDC__
		(new_volume)  If open of new archive fails, ask again
				(Is probably user error.)

	* tar.c   Replace #ifdef __GNU__ with #ifdef __STDC__

	* port.c  Clean up #ifdef and #defines a bit.
		(quote_copy_string)  Sometimes the malloc'd buffer
				would be up to two characters too short.

	* extract.c (extract_archive) Don't declare ind static.

	* create.c (dump_file)  Don't declare index_offset static.

	* diffarch.c  Remove diff_name variable, and always use
	head->header.name, which will always work, unlike diff_name, which
	becomes trash when the next block is read in.

Thu Mar  1 13:43:30 EST 1990	Jay Fenlason ([e-mail])

	* Makefile Mention the -NO_REMOTE option.
	* port.c Fix typo, and define WANT_FTRUNCATE on i386 machines.

Mon Feb 26 17:44:53 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* getdate.y: Declare yylex and yyerror as static.
	#define yyparse to getdate_yyparse.

Sun Feb 25 20:47:23 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* tar.c: Remove +old option, since it is a valid abbreviation of
	+old-archive, which does the same thing.
	(describe): A few small cleanups in message.

Mon Feb  5 14:29:21 EST 1990	Jay Fenlason	(hack@wookumz)

	* port.c  define LOSING_MSG on sparc, since doprnt_msg doesn't work.
		  Fix typo in #ifdef WANT_GETWD

Fri Jan 26 16:11:20 EST 1990	Jay Fenlason	(hack@wookumz)

	1.08	Sparse file support added.  Also various other features.

	* diffarch.c (compare_chunk)  Include correct arguments in
	a call to fprintf() for an error msg.
	(compare_chunks, compare_dir)  First argument is a long, not an int.

	* tar.c (options)  Use tar variable (argv[0]) as the name to print
 	in an error msg, instead of a constant "tar".
	(confirm)  Use external variable char TTY_NAME[] for name of file
	to open for confirmation input.

	* buffer.c (new_volume)  Ditto.

	* port.c  Add declaration for TTY_NAME[].

	* rmt.h  Add long declarations for lseek() and __rmt_lseek();

Tue Jan 23 14:06:21 EST 1990	Jay Fenlason (hack@wookumz)
	* tar.c, create.c  Create the +newer-mtime option, which is like
	+newer, but only looks for files whose mtime is newer than the
	given date.

	* rtape_lib.c  Make *both* instances of signal-handler stuff use
	void (*foo)() on USG systems.

Thu Jan 11 14:03:45 EST 1990  Jay Fenlason  (hack@wookumz)

	* getdate.y  Parse European dates of the form YYMMDD.
	In ftime()  Init timezone by calling localtime(), and remember that
	timezone is in seconds, but we want timeb->timezone to be in minutes.
	This small patch from Joergen Haegg  ([e-mail])

	* rtape_lib.c (__rmt_open)  Also look for /usr/bsd/rsh.
	Declare signal handler as returning void instead of int if USG is
	defined.
