- Standardize `fill` tool to use `value` instead of `text`.
- Add formatted output methods (`printInfoFmt`, `printErrorFmt`) to `Terminal`.
- Improve error handling in `ToolExecutor` and `browser/tools` by using error unions.
- Deduplicate `minify` utility and remove redundant code comments.
- Refactor tool dispatch to use `Action` enum tags instead of hardcoded strings.
ArenaPool previously maintained up to 512 16KB buckets. The 16KB retention is
small for things like XHR and scripts, but increasing it to something more
reasonably, like 128KB, would use up to 8x more memory.
This commit adds 4 buckets: 1KB, 4KB, 16KB and 128KB. Callers can request a
tiny, small, medium or large bucket. We end up using less memory peak memory
and less allocations.
Furthermore, callers can request a specific size. This is particularly useful
for WebSocket or Blob where the size could vary greatly (so we'd likely default
to a large bucket), but that could needlessly use up a large arena.
The bucket sizes were derived from analyzing allocations. A significant number
of allocations were very small. Things like ScheduleCallback and
FinalizerCallback are always less than 1K and can be generated in the thousands.
The 16KB retention was wasteful in these cases...better to have a large number
of 1K pools, so that we can have a handful of very large buffers.
Adds the SCROLL command and ensures WAIT actions are recorded.
Refactors TYPE to use the fill tool, adds self-heal retries, and
propagates agent failures to the process exit code.
Whenever we resolve a URL, say from `anchor.href`, we should consider the
document's charset when encoding the querystring. This probably isn't the
most important feature, but it makes tens of thousands of WPT cases pass, e.g
/encoding/legacy-mb-tchinese/big5/big5-encode-href-errors-han.html?3001-4000 and
/encoding/legacy-mb-japanese/euc-jp/eucjp-encode-href-errors-han.html?17001-18000
DOM elements previous called `URL.resolveURL(...)`. They now call
`self.asNode().resolveURL(...)`, where `Node#resolveURL` will provide the
document's charset.
Uses the newly added encoding_rs to implement TextDecoder for all encoding.
Claude wrote 100% of the Rust binding.
Improves various WPT tests, e.g. /encoding/api-basics.any.html.
Add a cache for v8 snapshot file.
Use a cache key for v8 snapshot with the last hash changing
src/browser/js/bridge.zig
eg. v8-snapshot-4dcb2c997e01e4367ca6118629fb4ac712f9692c
The "browser.markdown: block link" test expected the old format
([](url)). Updated to expect [url](url) since block-content
anchors without aria-label/title now use the href as display text.

When an anchor wraps block content (divs, images), the markdown dump
produced `([](url))` with empty display text. This is not valid
markdown and provides no useful information to LLMs consuming the
output.
Now uses the anchor's aria-label or title attribute as display text,
falling back to the href itself. Produces `[label](url)` instead.

When the snapshot isn't baked-into the binary, it requires more memory to
initialize and load. By changing the initializing order from: network, isolate,
snapshot to: isolate, snapshot, network we can reduce the peak startup memory.
This is because the short-live snapshot intermediary data and the long-lived
network data (certs) no longer overlap.
In https://github.com/lightpanda-io/browser/pull/1885 we added fallback to the
incumbent context when the current context had be released (by us, but not by
v8).
This now handles the case where there is no incumbent context. It's not clear
exactly why this can happen, but we do see it in some WPT tests (e.g.
/html/browsers/the-window-object/named-access-on-the-window-object/navigated-named-objects.window.html)
