changelog

ReactOS是一些高手根据Windows XP的内核编写出的类XP。内核实现机理和API函数调用几乎相同。甚至可以兼容XP的程序。喜欢研究系统内核的人可以看一看。

Mon Oct  5 21:33:14 1998  Norbert Warmuth  <[e-mail]>

	* screen.c (parse_display_format): Don't dereference NULL pointer
	when format string is an empty string.

Fri Oct  2 19:22:24 1998  Norbert Warmuth  <[e-mail]>

	* setup.c (panel_load_setup): equality operator used for assignment

	* setup.c: save and restore new global variable/option 
	ftp_use_unix_list_options	

Mon Sep 28 21:55:13 1998  Norbert Warmuth  <[e-mail]>

	* find.c: Changed hotkey of the continue-button (both Chdir and
	Continue used `C').

Tue Sep 15 21:52:00 1998  Norbert Warmuth  <[e-mail]>

	* mc.hlp, doc/mc.1.in, doc/mc.sgml: updated my EMail address

1998-09-14  Norbert Warmuth  <[e-mail]>

	* file.c (move_dir_dir): Fixed severe bug reported by Andrew Pechenov 
	<[e-mail]> (losing files when moving directories cross filesystem
 	boundaries): make sure erase_list is emptied always not only when we 
	deleted files.

1998-08-26  Ludovic Drolez <[e-mail]>

	* Made the program relocatable by using the MCHOME environment
	variable. 
	
Mon May 25 23:32:35 1998  Norbert Warmuth  <[e-mail]>

	* editdraw.c (print_to_widget): Ifdef'd SLang specific code in order 
	to make it compile with ncurses. Syntax highlighting in the
	internal editor is already disabled when SLang isn't used.

1998-05-24  Miguel de Icaza  <[e-mail]>

	* widget.c (port_region_marked_for_delete): New per-port
	piece of code:  Provides a way for good selection killing.

Sun May 24 02:45:03 1998  Norbert Warmuth  <[e-mail]>

	* utilunix.c, util.h (errno_dir_not_empty): deleted

Sat May 23 22:29:57 1998  Norbert Warmuth  <[e-mail]>

	* file.c (check_dir_is_empty): New function which takes a path and 
	returns -1 on error, 1 if there are no entries besides "." and
	".."  in the directory path points to, 0 else. This function
	actually opens and reads the directory and doesn't do tricks we
	used to do with rmdir.
	
	* file.c (erase_dir, erase_dir_iff_empty): Use check_dir_is_empty
	to detect non empty directories. The old code tried to remove the 
	directory and decided on errno whether the failure of rmdir was
	caused by a non empty directory or whether there was a different
	error. 
	Unfortunatly not every filesystem sets errno to EDIRNOTEMPTY if
	you try to delete a non empty directory. Namely the linux user
	space nfs server sets errno to EIO, Suns nfs server sets it to
	EEXIST and the AIX nfs server sets it to ??? (Steve reported
	problems on AIX so I guess AIX sets errno to a value we currently
	don't check).

1998-maj-18  Tamasi Gyorgy ([e-mail])

	* lib/mc.menu: 'Z' on 'tar.Z' and 'tar.z' files: '%f' -> '$1'.

	* lib/mc.ext.in.qnx.diff, lib/mc.menu.qnx.diff (QNX): modified
	'mc.ext.in' (tar -t: output to stderr); modified 'mc.menu' (tar is
	not GNU tar: doesn't know '-z'); support for '*.tar.F':
	'freeze'-compressed tar files [No automatic configure/install
	implemented: patches must be applied before running 'configure'
	(mc.ext.in.qnx.diff: this patch can be not only QNX-specific...)] 

	* lib/Makefile.in: 'mc.ext.in.qnx.diff' and 'mc.menu.qnx.diff' added
	to DISTLIB.

	* slang/sldisply.c:

	  SLTT_TRANSP_ACS_PATCH dependant code:

	  The problem: some terminals (QNX/qansi*, SCO OS5/ansi [?]) map the
	  whole upper half of the ASCII table to the lower half, when
	  alt-char-set is activated with the smacs/as string-sequence. This
	  means, that if 0 <= ch < 128 written to the terminal, it will be
	  translated to (ch+128) automatically by the terminal: so not only
	  the line-drawing characters can be written, when the alt-char-set
	  is activated. It implicitly means, that space, NL, CR, etc.
	  characters (exactly: anything besides the "standard" line drawing
	  characters) can not be written directly to the terminal, when the
	  alt-char-set is activated, because writing these characters
	  doesn't cause an implicit/temporary switching-back to the standard
	  char-set!

	  The original code in SLang assumes that space, NL, CR, etc. can be
	  printed when alt-char-set is activated. If SLTT_TRANSP_ACS_PATCH
	  is defined, the modified code will not use this assumption.
	  [Remark: the patch-code is not the most exact solution, but
	  works...]

	  QNX_QANSI_SLANG_COMPAT_ACS_PATCH dependant code:

	  A more OS/terminal-specific solution for the problem mentioned
	  above (->SLTT_TRANSP_ACS_PATCH).

	  If QNX_QANSI_SLANG_COMPAT_ACS is defined, the default smacs/sa,
	  rmacs/ae, acsc/ac [and sgr/sa, if it would be used!] command
	  sequences will be replaced internally with the "old style"
	  (pre-QNX 4.23) sequences in case of QNX/qansi terminals. Using
	  these optional command sequences the terminal remains compatible
	  with the original SLang code (without using the workaround-code
	  enabled by defining SLTT_TRANSP_ACS_PATCH).

	  Remark:

	  Currently SLTT_TRANSP_ACS_PATCH is not auto-configured by
	  'configure'. (Must be manually defined...)

	  There is some (QNX-specific) auto-configuration hand-coded in the
	  source:

	    #ifdef SLTT_TRANSP_ACS_PATCH
	    # if defined(__QNX__) && defined(QNX_QANSI_SLANG_COMPAT_ACS)
	    #  undef SLTT_TRANSP_ACS_PATCH
	    # endif
	    #else
	    # if defined(__QNX__) && !defined(QNX_QANSI_SLANG_COMPAT_ACS)
	    #  define QNX_QANSI_SLANG_COMPAT_ACS 1
	    # endif
	    #endif

	* slang/slutty.c: "newtty.c_iflag &= ~(ECHO | INLCR | ICRNL);"
	ECHO(0x08) is a c_lflag bit, it means PARMRK(0x08) in c_iflag. (!?!)

	* src/file.c: 'do_reget' can be extern if (USE_VFS && USE_NETCODE),
	not if (USE_VFS).

	* src/find.c (search_content()): Variable 'i' "must be" 'int', not
	'char'. ["i == -1": (buggy?) WCC 10.6 doesn't convert automatically
	(int)(-1) to (char)(-1) (GCC does), so "comparison result always 0"
	warning produced. It is cleaner to define 'i' as 'int', than cast
	'-1' to 'char', because 'read()' returns 'int'.]

	* src/key.c (init_key()): Call load_xtra_key_defines() and clear
	'use_8th_bit_as_meta' by default under QNX, if a 'qnx*' terminal
	detected. (A saved config file (mc.ini) can override it later...)

	* src/key.h: Declare load_xtra_key_defines().

	* src/keyxdef.c: Provides a method to define some platform-specific
	additional key mappings. (e.g. QNX terminals can handle most of
	META-? combinations as ALT-?...) ('keyxdef.c' currently not listed
	in doc/FILES...)

	* src/layout.c: TIOCGWINSZ must be available (so <sys/ioctl.h> (?)
	included), because window-resizing code doesn't work, if not defined.

	* src/main.c: 'print_usage()' is reserved name in the QNX run-time
	library, so 'print_usage()' renamed to 'print_mc_usage()'

	* src/mouse.c (QNX): ncurses 1.9.8a ported to QNX doesn't provide the
	'SP' pointer as a global symbol in the library, so the keyok()
	emulation currently can not be used under QNX (4.24 & Watcom C 10.6
	release version).

	* src/slint.c (QNX): 'qansi*' terminals added to the color_terminals[]
	list.

	* src/subshell.c, src/utilunix.c (QNX): include <unix.h> to get
	prototype for exec*()!!! [See README.QNX/Section 1.4 about the
	dangerous "No prototype for <function>" warnings emitted by Watcom C,
	if <function> is a 'printf()'-style function having variable number
	of arguments and you compile your source with the default register
	calling convention!!!]

	* Makefile.in: 'keyxdef' module added to SRCS and OBJS.

	* <mc-root>/README.QNX: QNX-specific notes.

	* <mc-root>/configure (line 3369), <mc-root>/configure.in (line 88):
	'test x$CCOPTS = x;' modified to 'test "x$CCOPTS" = x;'

	* <mc-root>/Makefile.in: README.QNX added to DISTMAIN.

Thu May 21 00:09:45 1998  Norbert Warmuth  <[e-mail]>
	
	* menu.c (menubar_event): Don't set menubar->selected to the
	invalid value -1. Fix for the bug reported by [e-mail]

	* menu.c (menubar_drop_compute): removed the check for inrange
	items which isn't necessary any longer.

Wed May 20 16:27:56 1998  Norbert Warmuth  <[e-mail]>

	* widget.c (history_put): input line history was defunct because
	there was an #ifndef where an #ifdef should be. 
	Btw. PORT_WIDGET_WANTS_HISTORY seems incomplete because a lot of
	history code is included even when this define is undefined.

1998-05-19  Tamasi Gyorgy <[e-mail]>

	* src/*: Until I get a better ChangeLog:  Tamasi's port of the
	code to QNX.

1998-05-19  Alexander Lukyanov <[e-mail]>

	* Makefile.in: Distirbution fix so that people are not forced to
	install gettext. 

1998-05-19  Miguel de Icaza  <[e-mail]>

	* ext.c: Memory leak fixed.

Mon May 18 22:24:09 1998  Norbert Warmuth  <[e-mail]>
	* lib/mc.ini.in: s/reges/regex/

	* main.c (process_args): return void, the return value was only
	used once but wrong (-h displayed help twice).
	(handle_args): -h: don't display help twice
	(print_usage): Don't print program name and version, that's
	already done by version(0).

	* menu.c (menubar_paint_idx): Highlight Hotkeys also on slow
	terminals (hotkeys were not displayed at all).

1998-05-18  Miguel de Icaza  <[e-mail]>

	* menu.c (menubar_drop_compute): Check for inrange items.

1998-05-15  Miguel de Icaza  <[e-mail]>

	* color.c (init_colors): Provide X-only version of color
	initialization. 

Thu May 14 01:56:11 1998  Norbert Warmuth  <[e-mail]>

	* configure.in: Don't add -lintl to LIBS when included gettext is
	used (further checks for libraries would fail because libintl.a
	isn't build, yet). Instead use and substitute LINTL.

	* Makefile.in (OURLIBS): add @LINTL@

Tue May 12 17:45:49 1998  <[e-mail]>

	* syntax.c: yet more minor modifications.

1998-05-11  Miguel de Icaza  <[e-mail]>

	* main.c: New default: auto-save setup.

	* screen.c (move_right, move_left): Add support for icon-view movement.

1998-05-09  Miguel de Icaza  <[e-mail]>

	* setup.c (panel_load_setup): On non-icon editions, fall back to
	list_full 

Sun May 10 13:27:50 1998  Norbert Warmuth  <[e-mail]>

	* widget.c (handle_char): Don't try to to delete default text in
	input widget more than once. Right after MC's start copy_filename
	(ESC Enter) failed because a flag wasn't cleared while characters
	were stuffed into the commandline (Andrej reported this bug). 

	* main.c (copy_readlink): usr mc_readlink instead of readlink

	* file.c: Changed default for the copy/move option "dive into
	subdir if exists" to off (note: this was only possible after the
	change in setup.c).

	(copy_dir_dir): Activated the previously uncommented code which
	implements "Dive into subdirs". Even when there's no case where we 
	actually would like that behaviour it is a documented feature. 
	Though I don't wanted to change the default behavour. Hence the 
	option change.
	
	(file_mask_defaults): set dive_into_subdirs

	(file_mask_dialog): Fix for debian Bug #20727: Move operation with 
	"[ ] Dive into subdir if exists" and destination filename not 
	wildcarded. If destination is an existing directory then files
	will be moved into this directory. If destination is not an
	existing directory then src file will be renamed (one file
	selected) or an error will be displayed (more than one file
	selected).

	(file_mask_dialog): made the option "Using shell patterns" local
	to the current copy/move operation, i.e. this option is always 
	initialized with the global options's value. Previously it affected 
	the global Options/Configuration/shell Patterns.
	Another possiblilty would be to make the global option a default
	option on startup and keep changes in the copy/move dialog
	(without saving these changes with save setup).

	* setup.c: Don't save and load options which can be changed
	outside the options menu. For example I don't like that
	preserve_uid_gid and dive_into_subdirs from the copy/move dialog
	are saved and restored (strange, what about the other options from 
	this dialog?). 
	It would be much cleaner to make these option read-only. This way
	one could edit ~/.mc/ini to provide default option setting on
	startup and "Save setup" wouldn't have side effects outside the
	option's menu.

Sun May 10 13:24:20 1998  Norbert Warmuth  <[e-mail]>

	* doc/mc.1.in, doc/mc.sgml, mc.hlp: Updated to reflect new default 
	for dive into subdirs.

Sun May 10 13:21:45 1998  Norbert Warmuth  <[e-mail]>

	* edit/syntax.c: Disable debug messages on stderr.
	
	* edit/edit.h: Added missing _()

1998-05-06  Miguel de Icaza  <[e-mail]>

	* layout.c (flag_winch): Propagate the window change to the slave
	pty even when not running our event loop.  The resize_subshell
	routine is thread safe. 

	* dlg.c (update_cursor, dlg_broadcast_msg_to): Do not send
	messages if no widgets are on the Dlg_head, this happens now with
	the gmc code, as we can have all of the windows shut down.
