`yarn add` queries Algolia's `npm-search` index to detect whether the added package needs a matching `@types` package. On restricted networks (eg. a corporate proxy that drops or refuses the request) this lookup had no timeout and could make `yarn add` hang indefinitely, while `yarn install` kept working against the configured registry. This caps the lookup at 10s and, on timeout or network failure, warns the user (pointing at the `tsEnableAutoTypes: false` / `YARN_TS_ENABLE_AUTO_TYPES="false"` escape hatch) before letting the install proceed without the `@types` package. It also hardens the Algolia requester so a connection error without a `response` no longer throws an unrelated `TypeError`. Closes yarnpkg#7111 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NS1JKnVAz9uPwdyUhfub2g

What's the problem this PR addresses?
Closes #7111
yarn addqueries Algolia'snpm-searchindex to detect whether the added package needs a matching@typespackage. In our corporate network, all egress traffic traverses our HTTP proxy. If this is set globally usingHTTPS_PROXY,HTTP_PROXY, andNO_PROXY, but not explicitly with Yarn's HTTP proxy config, this query will not go through the proxy but will instead try to make a direct connection. In our case, this means the firewall silently drops the connection.httpTimeoutis not what's bounding a single attempt. I dropped it from 15s to 10s and got an identical ~135s per attempt. The wait is the Linux kernel's TCP SYN-retry exhaustion (default tcp_syn_retries=6, ~127–135s in my tests). Because the TCP socket never establishes, got's timeout.socket (which is socket-inactivity-after-connect) never starts. Got then retries httpRetry times, which multiplies the dead time.My tests:
httpTimeout=10s httpRetry=0httpTimeout=10s httpRetry=1httpTimeout=15s httpRetry=1httpTimeout=1m httpRetry=3)How did you fix it?
This caps the lookup at 10s and, on timeout or network failure, warns the user (pointing at the
tsEnableAutoTypes: false/YARN_TS_ENABLE_AUTO_TYPES="false"escape hatch) before letting the install proceed without the@typespackage. It also hardens the Algolia requester so a connection error without aresponseno longer throws an unrelatedTypeError.Future fixes
My last comment in the linked issue proposes additional fixes to make this more stable, but I wanted to keep this PR small and easy to review. A future enhancement would be to have the Algolia lookup respect the global HTTP environments, just like the installation does today.
