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. |
