2009-05-21  Juan Cespedes <cespedes@debian.org>

	* Release version 0.5.2
	* new fork() and clone() approach:
	  + used PTRACE_O_TRACE{FORK,VFORK,CLONE} to trace newly created
	    processes instead of figuring it out whether a given syscall
	    would create another process or not
	  That way, new processes are always traced from the very beginning
	* Use PTRACE_O_TRACEEXEC to check if a process has called exec()

2009-05-07  Juan Cespedes <cespedes@debian.org>

	* clean-up of structs Process, Breakpoint, Function and Event

	* wait for new children to stop instead of assuming they have stopped

2009-02-11  Juan Cespedes <cespedes@debian.org>

	* Fixed bug present since the first version (!) of ltrace,
	  which caused many programs to segfault when a signal is received:
	  + When a breakpoint is hit, and we need to continue with it, we:
	    1) remove the breakpoint
	    2) order a SINGLESTEP
	    3) when control comes back, set the breakpoint again
	    4) let the process continue
	  + The problem came when a signal is received in the middle
	    of all this (specifically, between 2) and 3)).
	    If this is so, we treat the signal "in the usual way",
	    it is, at the end we issue a "CONTINUE" instead of the
	    needed SINGLESTEP.

2008-12-10  Juan Cespedes <cespedes@debian.org>

	* summary.c: Fix "ltrace -o -c"

	* ltrace.c: Close output file on exit
	* ltrace.c: use getenv("HOME") instead of getpwuid(geteuid())->pw_dir
	* read_config_file.c, display_args.c: remove "ignore" argtype;
	  that's what "void" is for
	* packaging/debian/: misc fixes, sync with version 0.5-2
	* etc/ltrace.conf: added more system calls
	* testsuite/ltrace.minor/trace-clone.c: sleep(1) to avoid earlier
	  termination of process

	  to wait for child to stop, as it stopped following clone()
	* process_event.c: Disable breakpoints before doing fork() (again!),
	  to make children work as expected

2007-05-10  Petr Machata  <pmachata@redhat.com>

	* Based on work of Supriya Kannery <supriyak@in.ibm.com>
	* wait_for_something.c, process_event.c: Tracing across exec.
	* sysdeps/linux-gnu/trace.c, ltrace.h: New interface was_exec.
	* testsuite/ltrace.minor/trace-exec.c,

	* sysdeps/linux-gnu/trace.c (trace_pid): wait for child to stop,
	as indicated by ptrace documentation.
	* proc.c (open_pid): start the traced child again, it will have
	been stopped after trace_pid.  Fixes tracing with -p.
	* breakpoints.c: initialize proc->breakpoints always, don't wait
	untill it might be needed.  This renders a check in insert_breakpoint
	superfluous.  Fixes a sigsegvs experienced with -L.

2006-12-28  Eric Vaitl  <evaitl@cisco.com>

	* sysdeps/linux-gnu/mipsel/* Added mipsel support
	* debug.h Added printf format attribute to debug_
	* elf.h Added mips relocation data to struct ltelf
	* elf.c (do_init_elf) Read mips relocation data

	instead of relplt_count.
	* process_event.c (process_breakpoint) For the mips, 
	conditionally add a new breakpoint if the address of the 
	function changes because of lazy relocation. 
	* breakpoints.c (enable_all_breakpoints) For the mips, 
	reinsert breakpoints after the child has been started.
