ptrace.ctypes_errnomodule: use directly the
- Remove the
ptrace.ctypes_errnomodule: use directly
ctypes.c_uint32, … types
python-ptrace 0.9 (2016-04-23)¶
- Add all Linux syscall prototypes
- Add error symbols (e.g. ENOENT), in addition to error text, for strace
- Fix open mode so O_RDONLY shows if it’s the only file access mode
- Python 3: fix formatting of string syscall arguments (ex: filenames), decode bytes from the locale encoding

- Fix to support Python 3.5
python-ptrace 0.8 (2014-10-05)¶
- Issue #9: Rewrite waitProcessEvent() and waitSignals() methods of PtraceProcess to not call waitpid() with pid=-1. There is a race condition with waitpid(-1) and fork, the status of the child process may be returned before the debugger is noticed of the creation of the new child process.
- Issue #10: Fix PtraceProcess.readBytes() for processes not created by the debugger (ex: fork) if the kernel blocks access to private mappings of /proc/pid/mem. Fallback to PTRACE_PEEKTEXT which is slower but a debugger tracing the process is always allowed to use it.

- syscall: fix prototype of socket()
python-ptrace 0.6.4 (2012-02-26)¶
- Convert all classes to new-style classes, patch written by teythoon
- Fix compilation on Apple, patch written by Anthony Gelibert

- Create follow, showfollow, resetfollow, xray commands in gdb.py. Patch written by Dimitris Glynos
- Project website moved to:
- Replace types (u)intXX_t by c_(u)intXX
- Create MemoryMapping.search() method and MemoryMapping now keeps a weak reference to the process
python-ptrace 0.6 (2009-02-13)¶
User visible changes:
- python-ptrace now depends on Python 2.5
- Invalid memory access: add fault address in the name
- Update Python 3.0 conversion patch

- Add a new example (itrace.py) written by Mark Seaborn and based on strace.py
- PtraceSyscall: store the instruction pointer at syscall enter (if the option instr_pointer=True, disabled by default)
- Remove PROC_DIRNAME and procFilename() from ptrace.linux_proc
- Fix locateProgram() for relative path
- Fix interpretation of memory fault on MOSVW instruction (source is ESI and destination is EDI, and not the inverse!)
python-ptrace 0.5 (2008-09-13)¶
- Write an example (the most simple debugger) and begin to document the code
- gdb.py: create “dbginfo” command
- Parse socket syscalls on FreeBSD
- On invalid memory access (SIGSEGV), eval the dereference expression to get the fault address on OS without siginfo (e.g. FreeBSD)
- Fixes to get minimal Windows support: fix imports, fix locateProgram()
- Break the API: - Rename PtraceDebugger.traceSysgood() to PtraceDebugger.enableSysgood() - Rename PtraceDebugger.trace_sysgood to PtraceDebugger.use_sysgood - Remove PtraceProcess.readCode()

- BUGFIX: Fix typo in gdb.py (commands => command_str), it wasn’t possible to write more than one command…
- BUGFIX: 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 (e.g. 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)¶
- 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
- 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
