fix(extension): only look for devframe on a loopback page - #25
erkamyaman wants to merge 1 commit into
Conversation
Opening the panel probed the inspected page for a connection file before anything checked its host, so visiting any site put requests for `/__ng-devtools/__devframe/__connection.json` and five more in that site's logs, and told it the extension is installed. The panel only ever connects to localhost or 127.0.0.1, so the result could not be used anyway. Read the origin first and stop there when it is not loopback. The probes also ran inside the page through eval(), which forced them to be synchronous XMLHttpRequests and blocked the page's main thread. Run them from the panel instead, where fetch can be awaited; the manifest already grants host access to exactly the two loopback hosts. The host check in loadPanel() stays as it was.

- Line 45: Bound each endpoint probe in loadPanel, including both the fetch
request and response JSON-body read, so a stalled probe times out and sequential
discovery can continue or fall back to standalone mode.
- Line 36: Update the findConnection(origin) flow before loadPanel so discovery
remains tied to the origin it probed. When discovery completes, compare the
inspected page’s current origin with the captured origin; if it changed, restart
discovery for the new origin or load standalone mode, and never pass the old
origin’s discovered base path to the new origin.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep the discovered origin tied to the panel URL.
If the inspected page navigates from one loopback origin to another while findConnection(origin) runs, unchanged loadPanel() evaluates the new origin at Line 69. It can then pass a base path discovered on the old origin to the new origin without probing it. Recheck the inspected origin when discovery completes, and restart discovery or load standalone mode if it changed.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Bound the time spent on each probe.
If the first endpoint accepts a request but does not finish its response or JSON body, the sequential search does not reach a later working endpoint. loadPanel() also remains pending. Apply a timeout to each probe, including its body read, so discovery can continue or fall back to standalone mode. (dom.spec.whatwg.org)
