|
|
* Namespace all expat exported symbols to avoid dynamic loading symbol
|
|
* collisions when embedding Python.
|
|
*
|
|
* The Problem:
|
|
* - you embed Python in some app
|
|
* - the app dynamically loads libexpat of version X
|
|
* - the embedded Python imports pyexpat (which was built against
|
|
* libexpat version X+n)
|
|
* --> pyexpat gets the expat symbols from the already loaded and *older*
|
|
* libexpat: crash (Specifically the crash we observed was in
|
|
* getting an old XML_ErrorString (from xmlparse.c) and then calling
|
|
* it with newer values in the XML_Error enum:
|
|
*
|
|
* // pyexpat.c, line 1970
|
|
* ...
|
|
* // Added in Expat 1.95.7.
|
|
* MYCONST(XML_ERROR_UNBOUND_PREFIX);
|
|
* ...
|
|
*
|
|
*
|
|
* The Solution:
|
|
* Prefix all a exported symbols with "PyExpat_". This is similar to
|
|
* what Mozilla does for some common libs:
|
|
* http://lxr.mozilla.org/seamonkey/source/modules/libimg/png/mozpngconf.h#115
|
|
*
|
|
* The list of relevant exported symbols can be had with this command:
|
|
*
|
|
nm pyexpat.so \
|
|
| grep -v " [a-zBUA] " \
|
|
| grep -v "_fini\|_init\|initpyexpat"
|
|
*
|
|
* If any of those symbols are NOT prefixed with "PyExpat_" then
|
|
* a #define should be added for it here.
