+
+2006-04-20  Hans-Bernhard Broeker  <broeker@physik.rwth-achen.de>
+
+	* src/input.c (askforreturn): If curses is handling the display,

+	
+	* src/mypopen.c [HAVE_IO_H]: #include <io.h> it, for the setmode()

+
+2006-04-19  Hans-Bernhard Broeker  <broeker@physik.rwth-achen.de>
+
+	General change: indentation width of touched areas changed to 4
+	spaces, open braces not on lines of their own, single-line "else
+	if", get rid of (void) casts of unused function return values.
+
+	* src/global.h (select_large): Removed declaration.
+
+	* src/main.c (select_large, main): Removed long unused global.
+
+	* src/dir.c (scan_dir): Get rid of d_ino check --- this field is
+	not reliably present in struct dirent, and doesn't achieve enough
+	to be worth autoconf-ing around.  Works around problems compiling on
+	Cygwin release 1.5.19.
+
+	* Makefile.in, aclocal.m4, configure, contrib/Makefile.in,
+	doc/Makefile.in, src/Makefile.in: Regenerated with current auto
+	tools (autoconf-2.59, automake 1.9.6).
+
+2006-02-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/vpinit.c (vpinit): Fix handling of slightly malformed VPATH
+	environment variable contents.
+
+2005-11-22  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/dir.c (issrcfile): Finally added auto-searching for
+	three-letter C++ file extensions *.tcc, *.cpp, *.cxx.  Test all
+	matches to be regular files, not just those with two- and
+	three-character extensions.
+
+	* src/invlib.c: Some cleanup.  Replace 0 third argument to fseek
+	by proper SEEK_SET.  Got rid of (void) result casts and some
+	function argument casts.
+	(invmake): Fix one sizeof(long)==4 assumption.
+
+2005-08-16  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/main.c: Uncluttered by removing nitpicky (void) casts.
+	(longusage): Reworked for source legibility even on 80-column
+	displays.
+	(main): If in verbose linemode, print number of references found,
+	first off.  Patch from Elad Lahav, for Kscope
+
+2005-07-08  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/build.c (invname_buf, invpost_buf, reffile_buf): Make
+	modifiable copies of the default file names.
+	(invname, invpost, reffile): Initialize pointers to modifiable
+	copies, rather than to string literals.
+
+	* packages/MSDOS/djmake.bat: Adapt to modern position of ylwrap
+	script.
+
+	* src/command.c (command) [KEY_RESIZE]: Protect by
+	!defined(__DJGPP__).  That platform doesn't have sigaction() and
+	associated machinery, nor does it really support terminal size
+	changes to begin with.
+
+	* src/main.c (sigwinch_handler): Likewise.
+	(main): Likewise.
+
+2005-04-29  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/command.c (command): Additional hotkey mapping of Ctrl-A to
+	same function as Ctrl-Y, like AT&T cscope, to evade Ctrl-Y
+	occupied as the DSUSP signal key on BSD'ish platforms.
+
+	* src/help.c (help): Document additonal hotkey ^A.  Mention
+	possible unavailability of some Ctrl keys because of terminal
+	settings.
+
+2005-03-14  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/input.c (getline): Removed.  Was just a minimally simplified
+	copy of mygetline() anyway, and it threatened to collide with a
+	like-named routine in libc.
+	
+	* src/global.h (getline): Removed prototype.
+
+ 	* src/command.c (command): Changed all calls of getline() to
+	mygetline() with an empty string as the first argument.
+
+	* src/egrep.y (memset): Changed #if condition around fallback
+	implementation to match that of the prototype in global.h.  Should
+	fix SF bug #1163104 (build failure on FreeBSD).
+
+2005-02-16  Neil Horman  <nhorman@gmail.com>
+
+	* src/command.c (command): Added ifdef KEY_RESIZE around
+	KEY_RESIZE case in switch statement to allow curses
+	libraries which don't support resize events to build
+
+	* src/main.c (main): Added ifdef KEY_RESIZE around 
+	SIGWINCH handler and signal registration logic to
+	remove resize code from cscope when building with
+	curses libraries that don't support resize events
+
+2005-02-04  Neil Horman  <nhorman@gmail.com>
+
+	* src/command.c (command): Added KEY_RESIZE event case to 
+	command switch to handle window re-drawing when a resize 
+	event was received.
+
+	* src/input.c (mygetch): Added error checking of return code
+	to restart call to getch in the event it returned early due
+	to a signal being delivered.
+
+	* src/main.c (main): Registered a signal handler for the 
+	SIGWINCH handler which is delivered when a terminal is 
+	resized.  Handler pushes a KEY_RESIZE event onto the head 
+	of the command input queue.
+
+2005-02-01  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/build.c (build): Keep interactive mode on, even if on a
+	terminal, if verbose mode (-v) was turned on.
+
+2005-01-31  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/scanner.h: Declare yytext signed on AIX (without stating a
+	version number, for now).
+
+2005-01-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/mypopen.c (mypopen): Make closing argument to execlp() a
+	manifest null pointer, not just a zero.
+
+2004-12-08  Neil Horman  <nhorman@gmail.com>
+	
+	* src/dir.c: Fix to dissallow unreadable files from 
+	srcfiles list (sourceforge bug number 1040690)
+
+2004-12-06  Neil Horman  <nhorman@gmail.com>
+	
+	* src/main.c: Fix for temp file security bug (sourceforge 
+	bug number 1062807 / CAN-2004-0970)
+
+2004-11-22  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* doc/cscope.1: Make ESR happy: change man page summary section to
+	avoid [0-9] syntax.
+
+2004-10-27  Hans-Bernhard Broeker  <broeker@accip02.physik.rwth-aachen.de>
+
+	* src/display.c (search): Replace duplicated code by a call to
+	countrefs().  Duplicate lacked adjustment of column widths in case
+	of very long function/file names.  Thanks to Darlene Wong for
+	spotting this.
+
+	* src/global.h (countrefs): Prototype added.
+
+	* src/command.c (countrefs): Made globally available.
+
+2004-06-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/dir.c (makefilelist): Fix broken movement of point_in_line
+	when parsing quoted names.  Simplify structure by moving default
+	handling upward.
+
+2004-06-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* contrib/ocs (SYSDIR): Only set to /usr/local/lib/cs if not
+	already set in outside environment.  Check that $(SYSDIR) exists
+	before proceeding.  From SF patch #976788 by Neil Horman.
+
+2004-04-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/vpinit.c (vpinit): Renamed argument currentdir to
+	current_dir to avoid name clash with same-named global.
+
+	* src/command.c (Pattern): Renamed from "pattern", to avoid
+	multitute of compiler warnings about shadowing by locally defined
+	variables of the same name.  Changed all usages of this variable,
+	too.
+	(command): Test for individual KEY_* macros instead of TERMINFO
+	whenever one of the KEY_* macros is referenced.  This should
+	reduce the TERMINFO mess a little.
+
+	* src/find.c (read_block): Renamed from "readblock", to avoid name
+	clash with QNX system function of that name.  Calls changed
+	accordingly, all over the place.
+
+	* src/display.c: Fix fall-back definition of sigjmp_buf.
+
+	* src/constants.h: Activate TERMINFO for FreeBSD.
+
+	* src/input.c (mygetline): New function.  Poor-man's readline
+	imitation.  From SF Patch #937310.
+
+	* src/global.h (mygetline): Prototype added.
+
+	* src/command.c (command): Use mygetline() instead of letting
+	ncsurses doing it all.  Make Ctrl-B/F special hotkeys that are
+	handled here instead of in mygetline(), to preserve their meaning.
+
+	* packages/cscope.spec: Updated by SF patch #920586 to be more
+	compatible with current expectations.
+
+2004-02-24  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* configure.in (AC_CHECK_HEADERS): Added check for NSK-Tandem
+	special magic header file <floss.h>.
+
+	* src/global.h [HAVE_FLOSS_H]: Added #include <floss.h> if it
+	exists.
+
+2004-02-14  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/command.c (countrefs): Fix off-by-one length specification
+	of %s format.  Thanks to <anil@recoil.org> for spotting it.
+
+2004-02-12  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	Fix SF bug #892731: Ctrl-C interruption of search works only once
+	per session.
+	
+	* configure.in (sigsetjmp): Added test for presence of this
+	function.
+
+	* src/display.c (sigsetjmp) [!HAVE_SIGSETJMP]: Provide fallback
+	definitions for functions sigsetjmp, siglongjmp and type
+	sigjmp_buf.
+	(search): Move call to signal() above that to setjmp().  Call
+	sigsetjmp() instead of setjmp().
+
+	* configure, config.h.in: Regenerated.
+
+	* Makefile.in, src/Makefile.in, contrib/Makefile.in,
+	doc/Makefile.in, aclocal.m4: Rebuilt by automake-1.7.9.
+	
+	
+2004-02-11  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* configure.in (signal.h) Check added.
+	(sighandler_t): Check for this type.  Should be defined on POSIX
+	platforms, but is treated as a GNU extension sometimes.
+
+	* src/global.h (sighandler_t) [!HAVE_SIGHANDLER_T]: Provide
+	fallback definition of function pointer typedef for signal
+	handlers if <signal.h> doesn't provide it. Simplifies cscope's
+	work when working on its own source code --- function pointers
+	confuse it quite badly, so it's best to minimize their visibility.
+
+	* src/input.c (mygetch): Type of local variable savesig written
+	using sighandler_t.
+
+	* src/display.c (search): Type of local variable savesig written
+	using sighandler_t.
+
+	* src/exec.c (oldsigtstp): Renamed, from oldsigstp.
+	(oldsigtstp,oldsighup,oldsigquit): Changed from function pointer
+	type to new typedef name sighandler_t.
+
+2004-02-05  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/global.h (tolower) [BSD]: Fix stupid typo in overrides for
+	toupper and tolower.
+
+2004-01-08  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/display.c (clearmsg): New function.  Does essentially the
+	same thing previously achieved by a rather more cryptic
+	postmsg("").
+	(postfatal): New function to printout a fatal error message and
+	terminate the program. Works like posterr(), but exits curses
+	first, so the message should end up visible after the program
+	exits.  Using this instead of posterr()+myexit() fixes SF bug
+	#419510.
+	(dispinit): Use postfatal:().
+	(postmsg): Use clearmsg().
+	(postmsg2): Call curses refresh() after change.
+
+	* src/global.h: Add prototypes for new functions clearmsg() and
+	postfatal().
+
+	* src/find.c (putsource): Use postfatal().
+
+	* src/main.c (main, skiplist): Use postfatal() and clearmsg().
+
+	* src/command.c (command): Use clearmsg().
+
+	* src/build.c (build, seek_to_trailer, movefile): Use postfatal().
+
+	* src/alloc.c (alloctest): Use postfatal().
+
+	* src/display.c (jumpback): Re-instate signal handler, in an
+	attempt to fix problems reported with the general behaviour of
+	signal handlers in cscope.
+
+	* src/scanner.l (ws, wsnl): Two new predefined patterns to catch
+	not only blanks and tabs, but all generally allowed white-space
+	characters in source files: form feeds, vertical tabs, carriage
+	returns.  Replaced most occurence of [ \t] and [ \t\n] by these.
+	This is a back-port from fscanner.l.  Should fix SF bug #508060.
+
+Wed Oct 15 16:05:46 2003  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/dir.c (scan_dir): Don't reduce path to basename before
+ 	calling issrcfile.
+	(issrcfile): Use either basename or full path, as necessary for
+ 	the individual tests.  Reorganized to reduce nesting.
+
+Mon Sep 15 12:34:46 2003  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/egrep.y (yylex, member, egrep, cgotofn): Reindented.  Fixed
+ 	implicit int declarations and casts.
+
+	* src/global.h (tolower, tolower) [BSD]: Fix override definitions
+ 	for these so they don't mung non-alphabetic input.
+
+Fri Sep 12 09:33:19 2003  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	* src/vp.h: Add #include of <sys/types.h> to fix problem on
+ 	Solaris.
+
+Fri Sep 12 09:33:19 2003  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
+
+	I'm finally starting a new, GNU-format ChangeLog file.  The format
+ 	of the previous was too terse to be really useful.  This begins
+ 	with the first changes after release 15.5.
+	
+	* ChangeLog.old: New file.  Renamed copy of old-format ChangeLog
+ 	file.
+
+	* ChangeLog: Started from scratch.
+
+
