## Changelog
|
||||
|
||||
### v0.1.8
|
||||
|
||||
- Compressed 5 residual internal/trivial docstrings (`MAX_RETRY_AFTER`, `_Retryable`,
|
||||
`_proxy_string`, `_retry_after`, `_attempt`) to one or two lines; no behavior change.
|
||||
|
||||
### v0.1.7
|
||||
|
||||
- Docstrings/comments compressed (module docstrings and internal-method prose); no
|
||||
behavior change. Public method contracts (`Webhook.send`, `WebhookResult` field
|
||||
docs) are unchanged.
|
||||
- Em-dash characters replaced with hyphens across the source.
|
||||
|
||||
### v0.1.6
|
||||
|
||||
- **429 `retry_after` no longer sleeps on an exhausted final attempt:** the wait is
|
||||
now carried to the START of the next attempt instead of slept immediately after
|
||||
seeing the 429. Previously the last (exhausted) attempt slept the full
|
||||
`retry_after` before giving up — a pointless wait since no retry followed. The
|
||||
wait is still honored (additive with aretry's backoff) before every attempt that
|
||||
actually runs.
|
||||
- Docs: `errors.py` no longer implies the missing-`[discord]`-extra raise is one of
|
||||
the exported error types — it's a plain `RuntimeError`.
|
||||
- Docstrings/comments compressed; no behavior change.
|
||||
|
||||
### v0.1.5
|
||||
|
||||
- **429 `retry_after` bounded:** a non-finite server-controlled wait (`inf`/`nan`, from
|
||||
the body `retry_after` or the `Retry-After` header) is now rejected outright, and a
|
||||
finite wait is clamped to `MAX_RETRY_AFTER` (300s). Previously a bare `float()` parse
|
||||
slept the value verbatim, unbounded and outside `max_retries` accounting — an
|
||||
adversarial or ms-vs-s-misconfigured server could stall a `send()` for hours.
|
||||
- **Connection/timeout errors now retry without a proxy provider:** previously
|
||||
`aiohttp.ClientError`/`asyncio.TimeoutError` with no `proxies=` set failed one-shot,
|
||||
contradicting both the README and the single most retry-worthy failure class. Now it
|
||||
retries under `commons.aretry`'s backoff, capped by `max_retries`, same as a 5xx —
|
||||
and still returns `ok=False` (never raises) once retries are exhausted. Proxy-rotation
|
||||
behavior (burn + rotate, capped by `max_proxy_retries`) is unchanged when a provider
|
||||
is set.
|
||||
|
||||
### v0.1.4
|
||||
|
||||
- **Never-raises net widened:** an unexpected exception that escapes a send attempt (a
|
||||
closed injected session → `RuntimeError`, a malformed proxy URL → `ValueError`) now
|
||||
converts to a falsy `WebhookResult(ok=False, ...)` instead of propagating out of
|
||||
`send()`, restoring the documented contract for those edge triggers.
|
||||
|
||||
### v0.1.3
|
||||
|
||||
- **429 always retries:** every `429` is now retryable under aretry's backoff + cap, not
|
||||
only those with a parseable `retry_after`. A 429 with no body `retry_after` and no
|
||||
`Retry-After` header (edge/Cloudflare/generic webhook) previously failed one-shot.
|
||||
|
||||
### v0.1.2
|
||||
|
||||
- Removed a dead `clock` constructor param (it was stored but never used). Pinned
