mod_storage_sql: Detect SQLite3 without UPSERT (or SQLCipher 3.x) SQLCipher v3.4.1 (the version in Debian 12) is based on SQLite3 v3.15.2, while UPSERT support was introduced in SQLite3 v3.24.0 This check was not needed before because we v3.24.0 has not been in a version of Debian we support for a long, long time. Note however that SQLCipher databases are not compatible across major versions, upgrading from v3.x to v4.x requires executing a migration. Attempts at making `prosodyctl mod_storage_sql upgrade` perform such a migration has not been successful. Executing the following in the `sqlcipher` tool should do the migration: PRAGMA key = '<key material>'; PRAGMA cipher_migrate;

-- Compatibility layer for bitwise operations

-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if rawget(_G, "bit32") then
	return _G.bit32;
end

do
	-- Lua 5.3 and 5.4 would be able to use native infix operators
	local ok, bitop = pcall(require, "prosody.util.bit53")
	if ok then
		return bitop;
	end
end

error "No bit module found. See https://prosody.im/doc/depends#bitop";
