Hello all, I am writing an extension library that contains some extensions, i.e. custom functions and collations. Some of these objects use some private data members in order to perform their calculations.
This extension library will be used by an embedded server that must handle many database connections to the same database file in different threads and it uses shared cache. I need to know whether SQLite synchronizes its invocations to the callbacks of these objects or whether I have to take care of protecting the data members these callbacks are using from concurrent access in my own code. >From what I understand, sqlite creates an instance of each extension object for each active sqlite3* database connection, therefore in single-thread and multi-thread mode I don't need to worry because sqlite3 itself may crash if a connection is accessed simultaneously by many threads. In serialized mode is it possibe for two threads using a single sqlite3* database connection to invoke an extension object at the same time without some sort of internal synchronization in sqlite3.dll? Thanks in advance. Constantine _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
