Bug tracker at http://code.google.com/p/psutil/issues 0.2.0 - 2010-11-13 ------------------ NEW FEATURES * Issue 79: per-process open files. * Issue 88: total system physical cached memory. * Issue 88: total system physical memory buffers used by the kernel. * Issue 91: per-process send_signal() and terminate() methods. * Issue 95: NoSuchProcess and AccessDenied exception classes now provide "pid", "name" and "msg" attributes. * Issue 97: per-process children. * Issue 98: Process.get_cpu_times() and Process.get_memory_info now return a namedtuple instead of a tuple. * Issue 103: per-process opened TCP and UDP connections. * Issue 107: add support for Windows 64 bit. (patch by cjgohlke) * Issue 111: per-process executable name. * Issue 113: exception messages now include process name and pid. * Issue 114: process username Windows implementation has been rewritten in pure C and no longer uses WMI resulting in a big speedup. Also, pywin32 is no longer required as a third-party dependancy. (patch by wj32) * Issue 117: added support for Windows 2000. * Issue 123: psutil.cpu_percent() and psutil.Process.cpu_percent() accept a new 'interval' parameter. * Issue 129: per-process number of threads. BUGFIXES * Issue 80: fixed warnings when installing psutil with easy_install. * Issue 81: psutil fails to compile with Visual Studio. * Issue 94: suspend() raises OSError instead of AccessDenied. * Issue 86: psutil didn't compile against FreeBSD 6.x. * Issue 102: orphaned process handles obtained by using OpenProcess in C were left behind every time Process class was instantiated. * Issue 111: path and name Process properties report truncated or erroneous values on UNIX. * Issue 120: cpu_percent() always returning 100% on OS X. * Issue 112: uid and gid properties don't change if process changes effective user/group id at some point. * Issue 126: ppid, uid, gid, name, exe, cmdline and create_time properties are no longer cached and correctly raise NoSuchProcess exception if the process disappears. API CHANGES * psutil.Process.path property is deprecated and works as an alias for "exe" property. * psutil.Process.kill(): signal argument was removed - to send a signal to the process use send_signal(signal) method instead. * psutil.Process.get_memory_info() returns a nametuple instead of a tuple. * psutil.cpu_times() returns a nametuple instead of a tuple. * New psutil.Process methods: get_open_files(), get_connections(), send_signal() and terminate(). * ppid, uid, gid, name, exe, cmdline and create_time properties are no longer cached and raise NoSuchProcess exception if process disappears. * psutil.cpu_percent() no longer returns immediately (see issue 123). * psutil.Process.get_cpu_percent() and psutil.cpu_percent() no longer returns immediately by default (see issue 123). 0.1.3 - 2010-03-02 ------------------ NEW FEATURES * Issue 14: per-process username * Issue 51: per-process current working directory (Windows and Linux only) * Issue 59: Process.is_running() is now 10 times faster * Issue 61: added supoprt for FreeBSD 64 bit * Issue 71: implemented suspend/resume process * Issue 75: python 3 support BUGFIXES * Issue 36: process cpu_times() and memory_info() functions succeeded also for dead processes while a NoSuchProcess exception is supposed to be raised. * Issue 48: incorrect size for mib array defined in getcmdargs for BSD * Issue 49: possible memory leak due to missing free() on error condition on * Issue 50: fixed getcmdargs() memory fragmentation on BSD * Issue 55: test_pid_4 was failing on Windows Vista * Issue 57: some unit tests were failing on systems where no swap memory is available * Issue 58: is_running() is now called before kill() to make sure we are going to kill the correct process. * Issue 73: virtual memory size reported on OS X includes shared library size * Issue 77: NoSuchProcess wasn't raised on Process.create_time if kill() was used first. 0.1.2 - 2009-05-06 ------------------ NEW FEATURES * Issue 32: Per-process CPU user/kernel times * Issue 33: Process create time * Issue 34: Per-process CPU utilization percentage * Issue 38: Per-process memory usage (bytes) * Issue 41: Per-process memory utilization (percent) * Issue 39: System uptime * Issue 43: Total system virtual memory * Issue 46: Total system physical memory * Issue 44: Total system used/free virtual and physical memory BUGFIXES * Issue 36: NoSuchProcess not raised on Windows when accessing timing methods * Issue 40: test_get_cpu_times() failing on FreeBSD and OS X * Issue 42: get_memory_percent() raises AccessDenied on Windows 0.1.1 - 2009-03-06 ------------------ NEW FEATURES * Issue 4: FreeBSD support for all functions of psutil * Issue 9: Process.uid and Process.gid now retrieve process UID and GID. * Issue 11: Support for parent/ppid - Process.parent property returns a Process object representing the parent process, and Process.ppid returns the parent PID. * Issue 12 & 15: NoSuchProcess exception now raised when creating an object for a nonexistent process, or when retrieving information about a process that has gone away. * Issue 21: AccessDenied exception created for raising access denied errors from OSError or WindowsError on individual platforms. * Issue 26: psutil.process_iter() function to iterate over processes as Process objects with a generator. * Process objects can now also be compared with == operator for equality (PID, name, command line are compared). BUGFIXES * Issue 16: Special case for Windows' "System Idle Process" (PID 0) which otherwise would return an "invalid parameter" exception. * Issue 17: get_process_list() ignores NoSuchProcess and AccessDenied exceptions during building of the list. * Issue 22: Process(0).kill() was failing on Windows with an unset exception * Issue 23: Special case for pid_exists(0) * Issue 24: Process(0).kill() now raises AccessDenied exception instead of WindowsError. * Issue 30: psutil.get_pid_list() was returning two instances of PID 0 on OS X and FreeBSD platforms. 0.1.0 - 2009-01-27 ------------------ * Initial release.
