update oracle cooloff and hit oracle server logic - #470
Conversation
WalkthroughChangesOracle context flow
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This change can combine oracle data from one block with orderbook data from the latest block, while concurrent requests may duplicate oracle traffic and the unbounded cache or cached failures may affect availability and recovery. The PR should address these bounded correctness and reliability risks, or have them explicitly accepted, before merge. Sequence Diagram(s)sequenceDiagram

Stabilize the cooloff timestamp assertions.
Each expectation calls Date.now() after recordOracleFailure calls it. A clock tick between the calls makes an exact equality assertion fail.
Mock Date.now() before the call, or assert a bounded timestamp range.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Coalesce concurrent fetches for the same block.
The cache is written only after fetchSignedContext resolves. If two quote paths request the same order pair and block while the first request is pending, both cache lookups miss and both send an oracle request.
Store an in-flight promise for the same URL, owner, order-pair key, and block number before awaiting the request. Reuse that promise, then retain its resolved Result in the completed-result cache.

Motivation
Updates cooloff for max profile owners and avoid hitting the server for an order pair if the block number has not elapsed since the last oracle request for that order pair, this is done through keeping an internal cache for each order pair latest oracle result.
