python-ptrace 0.4.2 (2008-08-28)

• BUGFIX: Fix typo in gdb.py (commands => command_str), it wasn't possible to write more than one command...
• BUGIFX: Fix typo in SignalInfo class (remove "self."). When a process received a signal SIGCHLD (because of a fork), the debugger exited because of this bug.
• BUGFIX: Debugger._wait() return abnormal process exit as a normal event, the event is not raised as an exception
• PtraceSignal: don't clear preformatted arguments (eg. arguments of execve)

python-ptrace 0.4.1 (2008-08-23)

• The project has a new dedicated website: http://python-ptrace.hachoir.org/
• Create cptrace: optional Python binding of ptrace written in C (faster than ptrace, the Python binding written in Python with ctypes)
• Add name attribute to SignalInfo classes
• Fixes to help Python 3.0 compatibility: don't use sys.exc_clear() (was useless) in writeBacktrace()
• ProcessState: create utime, stime, starttime attributes

python-ptrace 0.4.0 (2008-08-19)

Visible changes:

• Rename the project to "python-ptrace" (old name was "Ptrace)
• strace.py: create --ignore-regex option
• PtraceSignal: support SIGBUS, display the related registers and the instruction
• Support execve() syscall tracing

Developer changes:

• New API is incompatible with 0.3.2
• PtraceProcess.waitProcessEvent() accepts optional blocking=False argument
• PtraceProcess.getreg()/setreg() are able to read/write i386 and x86-64 "sub-registers" like al or bx
• Remove iterProc() function, replaced by openProc() with explicit call to .close() to make sure that files are closed
• Create searchProcessesByName()
• Replace CPU_PPC constant by CPU_POWERPC and create CPU_PPC32 and CPU_PPC64
• Create MemoryMapping object, used by readMappings() and findStack() methods of PtraceProcess
• Always define all PtraceProcess methods but raise an error if the function is not implemented

Version 0.3.2 (2008-07-25)

• Rewrite ip_int2str() using inet_ntoa() to avoid IPy dependency
• Add kill() and unlink() syscall prototypes
• Fix sign conversion error in ptrace() to fix error detection
• Catch OSError in ptrace.disasm (unable to find libdistorm64.so)
• PtraceDebugger.addProcess(): detach the process on exception
• Breakpoint: don't store bytes if the process is not running anymore
• writeError() now re-raise KeyboardInterrupt
• PtraceProcess: don't detach or terminate process if it is was running
• PtraceProcess: never send SIGTRAP signal to a process!

Version 0.3.1 (2008-07-08)

Minor update:

• ptrace.ctypes_errno: use ctypes_support.get_errno() when it's available
• Create RUNNING_PYPY constant is ptrace.os_tools
• Remove ptrace dependency from ptrace.pydistorm to be able to use it outside ptrace

Version 0.3 (2008-03-26)

• Support OpenBSD i386
• Use ptrace_io() on FreeBSD for faster readBytes()/writeBytes() methods
• Use ptrace_peekuser() to read registers on OS without ptrace_getregs() (eg. Linux 2.4 on PPC)
• Breakpoint works on PPC CPU (use TRAP instruction)
• Delete process and raise ProcessExit on abnormal process death (eg. detected by waitpid(pid))
• Write new Python binding to distorm64 library
• gdb.py: create "backtrace" command
• gdb.py: support operators in expressions (eg. $eip+4)

Version 0.2 (2008-02-14)

• Able to trace multiple processes
• Many new gdb.py commands: hexdump, signal, print, etc.
• Support i386 (Linux, FreeBSD), x86_64 (Linux) and PPC (Linux)
• Guess reason why a signal is sent: invalid memory read, stack overflow, division by zero, etc.
• Create simple C program to test strace.py and gdb.py
• Move files to three main modules: ptrace.binding, ptrace.syscall and ptrace.debugger

Version 0.1 (2008-02-08)

• First public release
