DOM.setFileInputFiles dispatched plain input/change events, so
event.isTrusted was false. Upload flows and anti-bot code that gate their
change handler on isTrusted ignored them, which silently broke the exact
case the feature targets. The Input domain already marks its synthesized
clicks/keys trusted via __obscura_markTrusted; do the same here.Fixes #384.
- fix(cdp): bound IO stream buffers so downloads cannot leak
Fetch.takeResponseBodyAsStream moved a response body out of the page's
LRU-bounded cache into CdpContext.io_streams, a server-lifetime map freed only
by an explicit IO.close. A client that opens a stream and disconnects, errors
mid-download, or never closes it leaked the full buffer forever; no teardown
path (WS close, Browser.close, Target.closeTarget) touched io_streams. That
reintroduced the unbounded memory growth streaming was meant to avoid (#360).Replace the raw map + counter with an IoStreamStore that caps the number of
open streams and their total bytes (OBSCURA_IO_STREAM_MAX_ENTRIES / _BYTES),
evicting the oldest first and always keeping the just-opened stream. Reading an
evicted handle fails cleanly, which is the right trade against an OOM. Read
chunking is unchanged.Fixes #386.
