调研方向

The issue names no source file, test, or entry point. Start by tracing sql.js's SQLite UDF registration and RESERVED_FUNCTION_POINTERS handling, then document whether repeated create_function calls or distinct functions consume pointers; a reproducible case and clear rule of thumb would define done.

描述

Hi,

I ran into Finished up all reserved function pointers. Use a higher value for RESERVED_FUNCTION_POINTERS -- I understand I could build sql.js with a higher value for RESERVED_FUNCTION_POINTERS, but I just wanted to make sure the issue was actually the number of UDFs:

is there a rule of thumb number of user defined functions? I ran into this problem with about 5 unique ones (but I call .create_function quite a few times because i need to update the udf) --- is the function pointers counted by distinct udf names, or the number that create_function is called?

Would the RESERVED_FUNCTION_POINTERS correspond directly to the number of .create_function or distinct UDFs, or neither of the two?

Thanks so much!!
