     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 a 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  */
