It has since been updated * to compile with BerkeleyDB versions 3.2 through 4.2. * * This module was started by Andrew Kuchling to remove the dependency * on SWIG in a package by Gregory P. Smith who based his work on a * similar package by Robin Dunn which wrapped * Berkeley DB 2.7.x. * * Development of this module then returned full circle back to Robin Dunn * who worked on behalf of Digital Creations to complete the wrapping of * the DB 3.x API and to build a solid unit test suite. Robin has * since gone onto other projects (wxPython). * * Gregory P. Smith is once again the maintainer. * * Use the pybsddb-users@lists.sf.net mailing list for all questions. * Things can change faster than the header of this file is updated. This * file is shared with the PyBSDDB project at SourceForge: * * http://pybsddb.sf.net * * This file should remain backward compatible with Python 2.1, but see PEP * 291 for the most current backward compatibility requirements: * * http://www.python.org/peps/pep-0291.html * * This module contains 6 types: * * DB (Database) * DBCursor (Database Cursor) * DBEnv (database environment) * DBTxn (An explicit database transaction) * DBLock (A lock handle) * DBSequence (Sequence) * */ /* --------------------------------------------------------------------- */ /* * Portions of this module, associated unit tests and build scripts are the * result of a contract with The Written Word (http://thewrittenword.com/) * Many thanks go out to them for causing me to raise the bar on quality and * functionality, resulting in a better bsddb3 package for all of us to use. * * --Robin */ /* --------------------------------------------------------------------- */ #include /* for offsetof() */ #include #define COMPILING_BSDDB_C #include "bsddb.h" #undef COMPILING_BSDDB_C static char *rcs_id = "$Id$"; /* --------------------------------------------------------------------- */ /* Various macro definitions */ #if (PY_VERSION_HEX < 0x02050000) typedef int Py_ssize_t; #endif #ifdef WITH_THREAD /* These are for when calling Python --> C */ #define MYDB_BEGIN_ALLOW_THREADS Py_BEGIN_ALLOW_THREADS; #define MYDB_END_ALLOW_THREADS Py_END_ALLOW_THREADS; /* For 2.3, use the PyGILState_ calls */ #if (PY_VERSION_HEX >= 0x02030000) #define MYDB_USE_GILSTATE #endif /* and these are for calling C --> Python */ #if defined(MYDB_USE_GILSTATE) #define MYDB_BEGIN_BLOCK_THREADS \ PyGILState_STATE __savestate = PyGILState_Ensure(); #define MYDB_END_BLOCK_THREADS \ PyGILState_Release(__savestate); #else /* MYDB_USE_GILSTATE */ /* Pre GILState API - do it the long old way */ static PyInterpreterState* _db_interpreterState = NULL; #define MYDB_BEGIN_BLOCK_THREADS { \ PyThreadState* prevState; \ PyThreadState* newState; \ PyEval_AcquireLock(); \ newState = PyThreadState_New(_db_interpreterState); \ prevState = PyThreadState_Swap(newState); #define MYDB_END_BLOCK_THREADS \ newState = PyThreadState_Swap(prevState); \ PyThreadState_Clear(newState); \ PyEval_ReleaseLock(); \ PyThreadState_Delete(newState); \ } #endif /* MYDB_USE_GILSTATE */ #else /* Compiled without threads - avoid all this cruft */ #define MYDB_BEGIN_ALLOW_THREADS #define MYDB_END_ALLOW_THREADS #define MYDB_BEGIN_BLOCK_THREADS #define MYDB_END_BLOCK_THREADS #endif /* Should DB_INCOMPLETE be turned into a warning or an exception?
