Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-12eval: keep references to function contextsJo-Philipp Wich
Otherwise the "this" context might be gc'ed before the function can access it. This bug manifested itself with long chained expressions such as: require("fs").open("file.txt").read(10) The file handle produced by open() was gc'ed before invoking read() on it due to the evaluation not increasing its refcount.

Also introduce convenience macro for registering function arrays in modules. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-10eval: fix function return value handling in expressionsJo-Philipp Wich
Since ut_invoke() takes care of unwrapping magic null, we don't need any special treatment for T_RETURN tags when processing expressions. Also drop T_BREAK case while we're at it since it cannot happen in this context. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-08parser, eval: use an ut_op flag to denote postfix accessJo-Philipp Wich
The current code still abused the JSON value pointer to denote postfix access for certain operations which led to a crash when freeing the parser state due to an attempt to put a (void *)1 pointer. Since we do have the ability to set flags on operations since the AST rework, use this much cleaner approach and avoid the invalid pointer hackery. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

A typo in the code lead to a null pointer dereference. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-07ast, eval, lexer: keep track of overflows when parsing numbersJo-Philipp Wich
This allows number literals that exceed the range INT64_MIN..INT64_MAX to be truncated to the respective min and max values in a defined manner. It also makes it possible to have the expression `{{ -9223372036854775808 }}` actually result in `-9223372036854775808`. Since negation and number declaration are separate operations, the value would be first truncated to `9223372036854775807` and then negated, making it impossible to write a literal INT64_MIN value without tracking the overflow. Also fix the number parsing logic to not trucate intergers to 32bit. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-07eval: adjust results for arithmetic division by nan, infinityJo-Philipp Wich
Follow ECMAScript logic. Division by zero yields infinity, division by infinity yields zero. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2020-09-06treewide: refactor internal AST structuresJo-Philipp Wich
