We have a sys.setdlopenflags() function, but required constants are not available on all platforms. The DLFCN is only available on Linux and sunos5 (is plat-sunos5 available for all Solaris and OpenIndiana versions?), but not on OpenBSD, FreBSD, Mac OS X, ... whereas these platforms have the sys.setdlopenflags() function. My patch contains 7 constants: - RTLD_LAZY - RTLD_NOW - RTLD_GLOBAL - RTLD_LOCAL - RTLD_NODELETE - RTLD_NOLOAD - RTLD_DEEPBIND (glibc >= 2.3) The ctypes has two RTDL constants: RTLD_LOCAL and RTLD_GLOBAL. The 2 constants are always available, even if the platform doesn't support them! Extract of _ctypes.c: ---------------------------------------- /* If RTLD_LOCAL is not defined (Windows!), set it to zero. */ #ifndef RTLD_LOCAL #define RTLD_LOCAL 0 #endif /* If RTLD_GLOBAL is not defined (cygwin), set it to the same value as RTLD_LOCAL. */ #ifndef RTLD_GLOBAL #define RTLD_GLOBAL RTLD_LOCAL #endif ---------------------------------------- Lib/plat-sunos5/DLFCN.py contains 25 constants, only 6 are available in my patch. I don't think that we should expose all constants. Using Google Codesearch, I only found one user of RTLD constants (of the DLFCN module). It's PyKDE4 who calls: sys.setdlopenflags(DLFCN.RTLD_NOW|DLFCN.RTLD_GLOBAL) I guess that the 7 constants should be enough for everyone :-) We may add more later on demand. You can add your own constant to your program if you really need a special option on a specific platform. |

Note that I'm really +10 on this issue: such constants belong to individual modules rather than to the unmanageable Lib/plat-XXX/. |

The patch looks fine to me. However, I don't think it meets Charles-François' requirement of moving the constants into an individual module. Rather than living in the unmanageable plat-XXX, they now live in the unmanageable posixmodule.c... |

Python/sysmodule.c still contains references to DLFCN module. |
