TypeMeta constains the index and the subtype. This allows retrieving the subtype
based on the actual value being bound, as opposed to the struct type. (I.e. it
returns the correct subtype when a Zig class is a proxy for another using the
Self declaration).
Internally store the subtype as an enum. Reduces @sizeOf(TaggedAnyOpaque) from
32 to 16.
Finally, sub_type renamed to subtype for consistency with v8.
The call arena doesn't consider nested calls (like, from callbacks). Currently
when a "call" ends, the arena is cleared. But in a callback, if we do that,
the memory for the containing code is no longer valid, even though it's still
executing.
For now, use the existing scope_arena, instead of the call_arena. In the future
we need to track the call-depth, and only reset the call_arena when we're done
with a top-level statement.
Also:
-Properly handle callback errors
-Increase wpt file size
-Merge latest loop.zig from zig-js-runtime.
Having a js source name is useful to detect where the error comes from.
Using `null` generates messages with `<anonymous>` source name.
eg. `ReferenceError: report is not defined\n at <anonymous>:1:1`
vs. `ReferenceError: report is not defined\n at teststatus:1:1`
index_get seems to be ~1000x slower than setting the value directly on the
v8.Object. There's a lot of information on "v8 fast properties", and values
set directly on objects seem to be heavily optimized. Still, I can't imagine
indexed properties are always _that_ slow, so I must be doing something wrong.
Still, for now, this brings back the original functionality / behavior / perf.
Introduce the ability for Zig functions to take a Env.JsObject parameter. While
this isn't currently being used, it aligns with bringing back the postAttach /
JSObject functionality in main.
Moved function *State to the end of the function list (making it consistent with
getters and setters). The optional Env.JsObject parameter comes after the
optional state.
Removed some uncessary arena deinits from a few webapis.
The HTTP response values _are_ mutable, but because we're using std.http.Header
the type is a `[]const u8`. This introduce a custom `Header` type where the
value is `[]u8`.
The goal is largely to allow more efficient value-comparison, by allowing
calling code to lower-case in-place. I specifically have the Mime parser in
mind:
25dcae7648/src/browser/mime.zig (L134)
Remove Env from caller, and don't store Env in isolate. We don't need it, we
can execute all runtime code from the Executor (which we store a pointer to
in the v8.Context)
In order to support click handling on anchors from JavaScript, we need some hook
from the page/session to the CDP instance. This first phase adds notifications
in page.navigate, as well as a primitive notification hook to the session.
CDP's existing Page.navigate uses this new notifiation system.
Combine uri + rawuri into single struct.
Try to improve ownership around URIs and URI-like things.
- cookie & request can take *const std.Uri
(TODO: make them aware of the new URL struct?)
- Location (web api) should own its URL (web api URL)
- Window should own its Location
Most of these changes result in (a) a cleaner Page and (b) not having to carry
around 2 nullable objects (URI and rawuri).
