close #42
Description
Fixes issue #42 in the Python SDK (
runinfra):_retry_delay_secondscalculated deterministic exponential backoff delays (base_seconds * (2 ** max(0, attempt - 1))) without adding random jitter. When upstream transient errors (such as429 Rate Limitor503 Service Unavailable) occurred across multiple client processes, all workers retried in exact lockstep at identical intervals (thundering herd)._retry_delay_secondsto include random full jitter (exponential + random.random() * base_seconds), matching the TypeScript SDK implementation (@runinfra/sdk).Testing & Verification
test_retry_delay_seconds_includes_jittertopython/tests/test_runinfra_sdk.py.base_seconds <= delay <= 2 * base_seconds).Ran 159 tests in 0.638s - OK).node scripts/verify-version-sync.mjs: Version sync intact at0.2.0.
