+
+2006-04-20 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+

+
+ * 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.
