Hi Here are a few remarks and questions about SQLITE_OMIT_LOOKASIDE and SQLITE_OMIT_TWOSIZE_LOOKASIDE: 1) SQLite has SQLITE_OMIT_LOOKASIDE to disable lookaside memory completely at compilation time. However, I see that some of the lookaside code is not disabled by SQLITE_OMIT_LOOKASIDE. For example, the struct sqlite3 contains this field: Lookaside lookaside; /* Lookaside malloc configuration */ ... which is not in between #ifdef SQLITE_OMIT_LOOKASIDE. It seems that we could save some memory per connections there if there were more #ifdef SQLITE_OMIT_LOOKASIDE or am I missing something? 2) SQLITE_OMIT_TWOSIZE_LOOKASIDE is new in SQLite-3.31. It's not documented at: https://sqlite.org/compile.html#_options_to_omit_features SQLITE_OMIT_WINDOWFUNC is also not documented in that page and perhaps others. 3) I assume that whether SQLITE_OMIT_TWOSIZE_LOOKASIDE is defined or not does not make any difference when SQLite is built with SQLITE_OMIT_LOOKASIDE. Is my assumption correct?
