|---|
| 20 |
"sub-registers" like al or bx |
|---|
| 21 |
* Remove iterProc() function, replaced by openProc() with explicit |
|---|
| 22 |
call to .close() to make sure that files are closed |
|---|
| 23 |
* Create searchProcessesByName() |
|---|
| 24 |
* Replace CPU_PPC constant by CPU_POWERPC and create CPU_PPC32 and CPU_PPC64 |
|---|
| 25 |

|---|
| 26 |
of PtraceProcess |
|---|
| 27 |

* Add kill() and unlink() syscall prototypes |
|---|
| 35 |
* Fix sign conversion error in ptrace() to fix error detection |
|---|
| 36 |
* Catch OSError in ptrace.disasm (unable to find libdistorm64.so) |
|---|
| 37 |
* PtraceDebugger.addProcess(): detach the process on exception |
|---|
| 38 |
* Breakpoint: don't store bytes if the process is not running anymore |
|---|
| 39 |
* writeError() now re-raise KeyboardInterrupt |
|---|
| 40 |
* PtraceProcess: don't detach or terminate process if it is was running |

|---|
| 49 |
* Create RUNNING_PYPY constant is ptrace.os_tools |
|---|
| 50 |
* Remove ptrace dependency from ptrace.pydistorm to be able to use |

|---|
| 55 |
|
|---|
| 56 |
* Support OpenBSD i386 |
|---|
| 57 |
* Use ptrace_io() on FreeBSD for faster readBytes()/writeBytes() methods |
|---|
| 58 |
* Use ptrace_peekuser() to read registers on OS without ptrace_getregs() |
|---|
| 59 |
(eg. Linux 2.4 on PPC) |
|---|
| 60 |
* Breakpoint works on PPC CPU (use TRAP instruction) |
|---|
| 61 |
* Delete process and raise ProcessExit on abnormal process death |
|---|
| 62 |
(eg. detected by waitpid(pid)) |
|---|
| 63 |
* Write new Python binding to distorm64 library |
|---|
| 64 |
* gdb.py: create "backtrace" command |
|---|
| 65 |
* gdb.py: support operators in expressions (eg. $eip+4) |
|---|
| 66 |
|
|---|
| 67 |

|---|
| 73 |
* Support i386 (Linux, FreeBSD), x86_64 (Linux) and PPC (Linux) |

overflow, division by zero, etc. |
|---|
| 76 |
* Create simple C program to test strace.py and gdb.py |
|---|
| 77 |
