Adrià Arrufat	b63d4cf675	mcp: improve RawJson stringification and schema formatting ... - Update `RawJson.jsonStringify` to parse and re-write JSON content, ensuring valid output. - Reformat tool input schemas in `tools.zig` using multi-line string literals for better readability.	2026-03-02 11:47:02 +09:00
Karl Seguin	03b999c592	Remove redundant CDP v8 shutdown ... https://github.com/lightpanda-io/browser/pull/1614 improved our shutdown behavior so that microtasks associated with a context wouldn't fire after the context was disposed of. This involved having context-specific microtasks, pumping the message loop, and prevent re-entry. The shutdown code in CDP already had much of this behavior built-in, but it has now become redundant. Most importantly the CDP shutdown logic did not prevent re-entry. Removing this code fixes a flaky WPT crash. I didn't seem to be tied to a specific test, but rather a cross-context/page use-after-free that was saw prior to 1614. I could reproduce it reliably by running `/wasm/core/`. I'll be honest, it isn't clear to me why _removing_ the CDP cleanup helps. Running the message loop and microtask _before_ our normal shutdown might be unnecessary, but why would it crash? I don't know, but the CDP path is slightly different in that it also involves Inspector shutdown. So there's still something about this flow I don't quite understand. And, at least for this case the current flow seems "correct".	2026-03-02 10:24:07 +08:00
Adrià Arrufat	a91afab038	mcp: improve event loop and response handling ... - Use an allocating writer in `sendResponse` to handle large payloads. - Update the main loop to tick the HTTP client and cap poll timeouts. - Update protocol version and minify tool input schemas.	2026-03-02 11:12:00 +09:00

Adrià Arrufat	41b81c8b05	mcp: use io poll for stdin and integrate message loop ... Replaces blocking stdin reads with `std.io.poll` to allow macrotasks to run. Removes the stdout mutex as I/O is now serialized.	2026-03-02 10:04:23 +09:00

Karl Seguin	84a949e7c7	Fix load event for page with no external scripts but with iframes ... Previously the "load" event happened when all external scripts were done. In the case that there was no external script, the "load" event would fire immediately after parsing. With iframes, it now waits for external script AND iframes to complete but the no-external-script code was never updated to consider iframes and would thus fire load events prematurely.	2026-03-01 18:19:40 +08:00

Karl Seguin	45196e022b	Add a "wpt" dump mode ... Adds a not-documented "wpt" mode to --dump which outputs a formatted report.cases. This is meant to make working on a single WPT test case easier, particularly with some coding tool. Claude recommended this output for its own use. Instead of telling claude to start the browser in serve mode, then run the wptrunner, and merge the two outputs (and then stop the server), you can do: zig build run -- fetch --dump wpt "http://localhost:8000/dom/nodes/CharacterData-appendChild.html" (you still need the wpt server up)	2026-02-28 19:08:58 +08:00
Karl Seguin	b9e4c44d63	Noop when document.open is called during iframe parsing ... I'm not sure what the correct behavior is, but this fixes a WPT crash: /html/browsers/sandboxing/sandbox-inherited-from-required-csp.html The issue is iframe-specific as, with an iframe, you document.write can be called during parsing when there's no document._current_script (because it's being executed from the parent).	2026-02-28 18:05:03 +08:00

Karl Seguin	e65667963f	Correctly JSON encode URL ... I think this code comes from some serialization tweak from when everything was an std.Uri and by switch to [:0]const u8 everywhere not only was the tweak unecessary, it was also wrong - possibly resulting in the generation of invalid JSON.	2026-02-28 12:48:45 +08:00

Karl Seguin	7fc6e97cd8	Re-implement forgiving base64 decode without intermediate allocation ... Was looking at, what I thought was a related issue, and started to extract this code to re-use it (in DataURIs). Realized it could be written without the intermediate allocation. Then I realized the dataURI issue is something else, but wanted to keep this improvement.	2026-02-28 11:22:31 +08:00
