| 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.
