| Please note that I have only seen this a few (3) times. I am unable to reproduce this. When I attempt to start IDLE from within Windows it does not bring up any window. When I tried to start it from the command line, I received this error: C:\Python23\Lib\idlelib>python idle.py Traceback (most recent call last): File "idle.py", line 23, in ? idlelib.PyShell.main() File "C:\Python23\lib\idlelib\PyShell.py", line 1271, in main flist.new() File "C:\Python23\lib\idlelib\FileList.py", line 62, in new return self.EditorWindow(self, filename) File "C:\Python23\lib\idlelib\PyShell.py", line 80, in __init__ EditorWindow.__init__(self, *args) File "C:\Python23\lib\idlelib\EditorWindow.py", line 186, in __init__ self.UpdateRecentFilesList() File "C:\Python23\lib\idlelib\EditorWindow.py", line 595, in UpdateRecentFilesList rfList=self.__CleanRecentFiles(rfList) File "C:\Python23\lib\idlelib\EditorWindow.py", line 620, in __CleanRecentFiles if not os.path.exists(path[0:-1]): File "C:\Python23\lib\ntpath.py", line 256, in exists st = os.stat(path) TypeError: stat() argument 1 must be (encoded string without NULL bytes), not str With a little print statement of what "path" is in this case, I found out that it is the following: ['\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 \x00\x00\x00\x00\x00'] I have worked around the problem by clearing out rfList on line 619 of EditorWindow.py. I'm guessing I'm getting into some sort of weird state but it is worth mentioning. |

| Logged In: YES user_id=149084 Error is produced by >>> import os >>> os.stat("foo\0.py") TypeError: stat() argument 1 must be (encoded string without NULL bytes), not str Error trace in reverse (using my posix box): Python/getargs.c: convertsimple() convertitem() vgetargs1() PyArg_ParseTuple(path, "et:stat", ...) Modules/posixmodule.c: posix_do_stat(self, path, "et:stat", STAT, NULL, NULL) posix_stat(self, path) posix_do_stat() does path validity checks before calling the system stat function. The "et" format doesn't allow embedded nulls, and the error is a TypeError from convertsimple(), rather than the os.error [no path] that ntpath.py: exist() is expecting. Nulls in a path cause a lot of functions in os.path to break. 1. Should this be fixed? 2. If so, in posix_do_stat() ? 3. Or in [ntpath, posixpath, macpath] by s/os.error/(os.error, TypeError)/ ? 4. Or just put a test in IDLE? Assigning to Martin for an opinion. |

| Logged In: YES user_id=21627 The posix module is behaving correctly here, I cannot see a problem. Posix does not allow file names with embedded NUL bytes, as open(2), stat(2) etc. take a null-terminated string, so it is *impossible* to use a string with embedded null bytes as a path name. If the posix module would allow embedded NUL bytes, the system would silently truncate the file name, and create/stat a file with a different name. Therefore, the posix module must perform the test and raise an exception. |
