…sting without moving payment or the NFT
…estroys the shared cache on construction
📝 WalkthroughWalkthroughThe pull request adds sample-based benchmark p95 calculation, upgrades the NFT marketplace with payment and escrow settlement, and adds public cache configuration and invalidation APIs. ChangesBenchmark metrics
NFT marketplace
Cache management
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The current head changes shared oracle-cache behavior and also includes marketplace and benchmark updates. It still has a shared-TTL consistency bug, cache-test/configuration failures, and an unresolved escrow lifecycle where bids can survive cancellation and apply after relisting; benchmark baselines may also be incompatible with the new percentile. These issues make the PR not merge-ready until corrected or explicitly accepted by the owners. Sequence Diagram(s)sequenceDiagram

- Line 60: Update the benchmark baseline workflow around compareReports and the
p95Ms metric so micro.json and micro.ci.json are regenerated with true p95
values, or validate and reject baselines carrying an incompatible older metric
version before comparison.
In `@packages/core/oracles/src/cache/price-cache.ts`:
- Around line 45-48: Update PriceCache.setPrice and
PriceCache.setAggregatedPrice to use the current shared “oracle-price” channel
TTL when writing entries, so later configuration applies consistently to
existing instances; alternatively, make constructor TTL explicitly
instance-local and remove the last-channel-configuration-wins behavior.
In `@packages/core/stellar-sdk/jest.config.cjs`:
- Line 41: Update the Jest resolver configuration to use the installed
ts-jest-resolver package name instead of the unavailable ts-jest/resolver
subpath, and add ts-jest-resolver to the workspace devDependencies.
In `@packages/core/stellar-sdk/src/cache/cache-manager.ts`:
- Line 130: In the configuration update flow, resize the relevant InMemoryCache
successfully before assigning the new value to this.configs[type]. Update the
logic around the resize operation so an invalid partial.maxSize leaves the
existing configuration and cache capacity unchanged.
In `@packages/core/stellar-sdk/src/cache/in-memory-cache.ts`:
- Around line 193-195: Update InMemoryCache.resize validation to reject
non-integer maxSize values while preserving nonnegative integer capacities.
Enforce zero-capacity behavior in the cache write methods set and setSync by
skipping storage when the configured maximum is zero, and ensure fractional
capacities cannot permit more entries than the configured limit.
In `@packages/core/stellar-sdk/src/test/in-memory` cache.test.ts:
- Line 1: Update the InMemoryCache import in the cache test to reference the
implementation under the cache directory, using the existing module extension
convention.
In `@packages/core/stellar-sdk/src/test/price-cache.test.ts`:
- Around line 9-12: Update the imports in the price-cache test to resolve
PriceCache, PriceData, and AggregatedPrice from the shared oracles source using
the correct ../../../oracles/src paths, and update SOURCE_FILE to point to the
actual price-cache.ts location there so readFileSync no longer targets a missing
file.

Make shared TTL configuration apply to all PriceCache writes.
Line 45 updates the channel TTL, but existing PriceCache instances continue to write with their own this.config.ttlMs at setPrice and setAggregatedPrice. For example, a first instance with ttlMs: 1000 still writes one-second entries after a second instance configures the shared channel with ttlMs: 5000.
Use the current shared channel TTL for writes, or define constructor TTL as instance-local and remove the claim that the last channel TTL configuration wins.

Import the cache module from its cache directory.
This path resolves to src/in-memory-cache.js, but the implementation is src/cache/in-memory-cache.ts. The test suite will fail module resolution. Use ../cache/in-memory-cache.js.

Fix the cross-package paths before running these tests. ../../src/... resolves under packages/core/stellar-sdk/src, so TypeScript cannot resolve PriceCache, PriceData, or AggregatedPrice. SOURCE_FILE also targets a missing file, causing readFileSync to fail with ENOENT. Use ../../../oracles/src/... or move the test.

Update the imports in the price-cache test to resolve PriceCache, PriceData, and
AggregatedPrice from the shared oracles source using the correct
../../../oracles/src paths, and update SOURCE_FILE to point to the actual
price-cache.ts location there so readFileSync no longer targets a missing file.

closes: [FIX] Oracles:
PriceCachemutatesglobalCacheprivate internals and destroys the shared cache on construction #410 — Oracles: PriceCache no longer mutates globalCache private internals or destroys the shared cache on constructionWhat was wrong
PriceCache's constructor reached throughas anyintoglobalCache'sprivate
configs/cachesfields, and — whenmaxSizewas supplied —replaced the live shared
oracle-priceInMemoryCacheinstance outright,silently dropping every entry any other holder had already cached.
invalidate()had a milder version of the same problem, walking theprivate
cacheMap directly to do prefix-scoped deletes.What this PR changes
packages/core/stellar-sdk/src/cache/in-memory-cache.ts— new publicAPI, replacing the need for any external private-field access:
resize(newMaxSize)— changesmaxSizein place. Growing isalways non-destructive; shrinking evicts only the minimum number of
entries needed (oldest-first, the same policy
set/setSyncalreadyuse), never the whole cache.
deleteByPrefix(prefix)— deletes every entry whose key starts withprefix, returns the count removed.keys()— read-only snapshot of current keys, so callers that need toscan/categorize entries (e.g. by prefix, for stats) don't need the raw
Map or entry values.
getMaxSize()— read accessor.packages/core/stellar-sdk/src/cache/cache-manager.ts:configure(type, partial)— the public replacement for(globalCache as any).configs[type] = .../caches.set(type, new ...).Merges into the channel's config; if
maxSizechanges, resizes theexisting
InMemoryCachein place via the newresize()— the instanceis never replaced, so entries survive.
deleteByPrefix(type, prefix)— public wrapper over the newInMemoryCache.deleteByPrefix.getConfig(type)— read accessor for a channel's effective config.invalidate()is refactored to usedeleteByPrefixinternally insteadof its own
(cache as any).cachereach-through (this was a second,pre-existing instance of the same anti-pattern inside
CacheManageritself — fixed it while I was in there, since the acceptance criteria
ties correctness to a cache-manager refactor not breaking anything
downstream, and this makes
invalidateitself refactor-safe too).packages/core/oracles/src/cache/price-cache.ts— full rewrite: zeroas anyanywhere in the file.globalCache.configure('oracle-price', {...})instead of reaching into private fields. Documented explicitly in a
doc comment:
PriceCacheintentionally shares the process-wideoracle-pricechannel by design (per the file's own header — "theDevKit unified caching singleton"), so reconfiguring
maxSize/ttlMsreconfigures that shared channel non-destructively rather than giving
each instance a private cache. That's requirement 5 from the issue
("decide and document ownership") — shared-by-design was the existing,
intentional architecture; the fix makes reconfiguring it safe instead
of changing the ownership model.
invalidate(symbol)now usesglobalCache.deleteByPrefix(...)insteadof walking a private Map.
clear()andgetStats()use the newdeleteByPrefix/keys()publicAPI instead of
(cache as any).cache.Files

jest.config.js's own comments point at (itstestPathIgnorePatternsspecifically calls out excluding helpers/mockswithin

team's actual convention differs — nothing else depends on the path.
