From a63d9f4d9fdd4d659d80628e4429129351fc61cb Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Wed, 24 Jul 1996 01:31:37 +0000 Subject: [PATCH] As a side effect of calling PySys_SetArgv (setpythonargv), the directory containing argv[0] is inserted in front of sys.path. If argv[0] contains no directory, an empty string is inserted. If argv is empty, nothing happens. --- Python/sysmodule.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/Python/sysmodule.c b/Python/sysmodule.c index 8937c857d49..1b6fab87b9c 100644 --- a/Python/sysmodule.c +++ b/Python/sysmodule.c @@ -364,5 +364,23 @@ setpythonargv(argc, argv) fatal("no mem for sys.argv"); if (sysset("argv", av) != 0) fatal("can't assign sys.argv"); + if (argc > 0) { + object *path = sysget("path"); + if (path != NULL) { + char *p = strrchr(argv[0], SEP); + int n; + object *a; + if (p == NULL) + n = 0; + else + n = p + 1 - argv[0]; + a = newsizedstringobject(argv[0], n); + if (a == NULL) + fatal("no mem for sys.path insertion"); + if (inslistitem(path, 0, a) < 0) + fatal("sys.path.insert(0) failed"); + DECREF(a); + } + } DECREF(av); }
