1 /* Copyright (c) 2005-2006 ActiveState Software Inc. 2 * 3 * Namespace all expat exported symbols to avoid dynamic loading symbol 4 * collisions when embedding Python. 5 * 6 * The Problem: 7 * - you embed Python in some app 8 * - the app dynamically loads libexpat of version X 9 * - the embedded Python imports pyexpat (which was built against 10 * libexpat version X+n) 11 * --> pyexpat gets the expat symbols from the already loaded and *older* 12 * libexpat: crash (Specifically the crash we observed was in 13 * getting an old XML_ErrorString (from xmlparse.c) and then calling 14 * it with newer values in the XML_Error enum: 15 * 16 * // pyexpat.c, line 1970 17 * ... 18 * // Added in Expat 1.95.7. 19 * MYCONST(XML_ERROR_UNBOUND_PREFIX); 20 * ... 21 * 22 * 23 * The Solution: 24 * Prefix all exported symbols with "PyExpat_". This is similar to 25 * what Mozilla does for some common libs: 26 * http://lxr.mozilla.org/seamonkey/source/modules/libimg/png/mozpngconf.h#115 27 * 28 * The list of relevant exported symbols can be had with this command: 29 * 30 nm pyexpat.so \ 31 | grep -v " [a-zBUA] " \ 32 | grep -v "_fini\|_init\|initpyexpat" 33 * 34 * If any of those symbols are NOT prefixed with "PyExpat_" then 35 * a #define should be added for it here. 36 */ 37 38 #ifndef PYEXPATNS_H 39 #define PYEXPATNS_H 40 41 #define XML_DefaultCurrent PyExpat_XML_DefaultCurrent 42 #define XML_ErrorString
