* fix(guardrails): keep the upstream error when a /v1/messages stream ends in one Raw-SSE guardrail stream hooks assembled the whole stream, and the Anthropic chunk parser raises on an error event, so a stream the upstream ended with event: error failed assembly. tool_permission then blocked it with a 400 that hid the upstream error, bedrock and model_armor emitted a could-not-assemble block, and presidio skipped masking. Assembly now leaves the error events out, so the delivered content is checked as usual and a clean stream passes through with its error frame. A rewritten stream ends with the upstream error instead of a message_delta and message_stop the upstream never sent. tool_permission also passes a stream of only error frames, which carries no tool call to check. * fix(guardrails): do not close a block the failed upstream left open when re-emitting a rewritten stream * fix(guardrails): check only the finished blocks of a stream cut off by an upstream error tool_permission and Presidio now assemble an error-ended stream through the error with an opt-in keyword, leaving out a tool call or thinking block the upstream cut off. Logging, OpenTelemetry, Bedrock, and Model Armor keep the old assembly. A rewrite drops the text block stop only when the upstream left its text block open. * fix(guardrails): keep a cut-off tool call from the client and stop each rewritten block before the next starts A failed stream holding a cut-off tool_use is now re-emitted through the rewrite, which leaves the call out and keeps the upstream error, so a denied call never reaches the client. The rewrite leaves its text block open only when it is the last block, and keeps a message_delta the upstream sent before failing. The new tool_permission tests no longer patch should_run_guardrail. * fix(guardrails): pass a cut-off stream with nothing denied through as sent, minus the cut-off tool call Re-emitting such a stream through the rewrite sent an empty text block and stopped it, and Claude Code does not retry a failed stream that shows a finished block, so it showed a mid-response error instead of retrying. Dropping only the cut-off call's events keeps the stream as the upstream sent it. * fix(guardrails): strip a cut-off tool call only from a stream the upstream failed Assembly leaves unfinished blocks out of the check only when the stream carries an upstream error event, so a stream with an unfinished but allowed tool call and no error frame now reaches the client as sent instead of losing a call the check already read * test(guardrails): type the parameters of the new stream error tests * fix(guardrails): skip SSE data lines that are not JSON objects when reading a stream A data line holding a bare JSON value such as 5 made the stream helpers call .get on an int, so tool_permission and Presidio answered 500 where main answered 400 or passed the stream through * fix(anthropic): skip SSE data lines that are not JSON objects when assembling a stream * test(guardrails): annotate the upstream error stream tests * fix(anthropic): read a stream's non-object lines and named error frames the same way everywhere Run the skip for a data line that is not a JSON object through extract_sse_data and the assembler loop, so the usage fallback keeps a stream's tokens and the chat handler keeps its contract. Presidio now holds a leading non-object frame until the first object frame, so the rest of the stream is still masked or blocked. An event: error frame now counts by its name, so a rewrite keeps it. * fix(guardrails): refuse an unreadable stream in Presidio and cut every kind of tool call A non-object JSON line with no Anthropic frame after it now gets a 400 from Presidio before any data byte, since passing it would send text main refused. A frame named error stays a normal event when its data is another Anthropic event. server_tool_use and mcp_tool_use cut off by an upstream error are dropped like tool_use, and a leading frame with empty data is relayed at once. * fix(guardrails): refuse what Presidio cannot read past a non-object line and keep non-string error types out of the frozenset Presidio now refuses a stream assembly cannot read when it holds a non-object data line, instead of relaying it unmasked. Non-string event types no longer crash a rewrite, and a CRLF stream that opens with a typed error is no longer read as one error, so its tool calls are still checked. * fix(guardrails): refuse a first frame whose type is a list or dict in Presidio Presidio passed PII at 200 where main answered 500 when the first read was a JSON object with a list or dict type, or a JSON array with a character cut at the end of the read. has_unreadable_json_event now reads both as data no reader of these streams can take, so the first-frame check refuses them. * test(guardrails): cover Presidio's refusal when a word or null line comes before a Gemini stream The first read then holds the unreadable line behind one Presidio can pass, so the check has to look at every frame in it. * fix(guardrails): treat a stream as error-only only when every data frame is an error A tool call split over data: lines beside one error frame read as error-only, so tool_permission passed it, and an SDK joins those lines and reads the call. The check now joins a frame's data lines and refuses anything but an error. * fix(guardrails): refuse a stream past an upstream error when a client could read a frame differently Run 8 of the live risk pass showed each stream reader imitating a client and missing a shape: a whitespace-led data line, an error key with no type, a split tool call after a plain message_start. An error frame now has to be plain, and assembly past an error returns None for any frame a client could read differently, so those streams keep main's refusal. * fix(guardrails): on a failed upstream, deliver only what tool_permission read A failed stream now reaches the client through the rewrite that already serves a denial, followed by the upstream error, even when nothing is denied. Raw frames could carry a tool call the check never read in shapes such as a reused block index, mixed line ends, a tool in message_start, interleaved deltas, or a form feed, and each refusal rule only moved the search to the next shape. The error frame goes out as its event name and first data line. An error is found at CR, LF and CRLF line ends, and the rewrite adds no finished block when it read no text, so Claude Code still retries the stream. * fix(guardrails): read an error frame's name as clients do and send the error alone when a rewrite cannot be built A data-less event: error frame with junk after the name is an unknown event to both SDKs, so a healthy stream stays raw. A finished tool call whose input is not JSON cannot be rebuilt, so a failed stream sends its upstream error alone, and a healthy stream still raises as before. * fix(guardrails): read an error frame as a client dispatches it and keep its JSON whole Only the last event line of a frame a blank line ended names an error, so a healthy stream with a later event line or an unterminated error is no failed stream. Any rebuild failure on a failed stream now sends the upstream error alone with a warning, a param rule denies an input nested too deep, and a raw line break inside a JSON error stays escaped so every reader gets it whole. --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/unit
This folder can only run mock tests.
