fix(core): reject truncated subagent write_file calls#3505

Propagate MAX_TOKENS truncation from subagent responses into tool requests and reject truncated edit calls before schema validation can surface misleading missing-parameter errors. Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

When a streaming response hits MAX_TOKENS and is retried, accumulated state variables (functionCalls, wasOutputTruncated, roundText, etc.) were not cleared. This caused a successful retry to inherit the stale wasOutputTruncated=true flag from the failed attempt, incorrectly rejecting all Edit tool calls with a truncation error. Reset all per-attempt state on retry events, matching the existing behaviour in turn.ts. Add a regression test covering the truncated-then-retried-successfully scenario. 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code)

Took this for a thorough verification run before merge — local test suite (5896 tests) is green, typecheck/build clean, both new tests pass. One small coverage suggestion before merge if you have a moment: The existing test Without it('should discard pre-retry function calls so only the retried call executes', async () => {
const writeFileToolDef: FunctionDeclaration = {
name: WriteFileTool.Name,
description: 'Writes a file',
parameters: { type: Type.OBJECT, properties: {} },
};
const { config } = await createMockConfig({
getFunctionDeclarationsFiltered: vi
.fn()
.mockReturnValue([writeFileToolDef]),
getTool: vi.fn().mockImplementation((name: string) => {
if (name === WriteFileTool.Name) {
return new WriteFileTool(config);
}
return undefined;
}),
});
const toolConfig: ToolConfig = { tools: [WriteFileTool.Name] };
const toolResultEvents: AgentToolResultEvent[] = [];
const eventEmitter = new AgentEventEmitter();
eventEmitter.on(AgentEventType.TOOL_RESULT, (event: unknown) => {
toolResultEvents.push(event as AgentToolResultEvent);
});
// Round 1: emit a (would-be) tool call, then a retry, then a different
// tool call. The retry handler must reset the accumulated functionCalls
// array — otherwise BOTH calls execute and the pre-retry one (which
// was supposed to be discarded) leaks into tool execution.
let callCount = 0;
mockSendMessageStream.mockImplementation(async () => {
callCount++;
if (callCount === 1) {
return (async function* () {
yield {
type: 'chunk',
value: {
functionCalls: [
{
id: 'call_pre_retry',
name: WriteFileTool.Name,
args: {
file_path: '/tmp/pre-retry.txt',
content: 'should-not-run',
},
},
],
},
};
yield { type: 'retry' };
yield {
type: 'chunk',
value: {
functionCalls: [
{
id: 'call_post_retry',
name: WriteFileTool.Name,
args: {
file_path: '/tmp/post-retry.txt',
content: 'should-run',
},
},
],
},
};
yield {
type: 'chunk',
value: {
candidates: [
{ finishReason: 'STOP', content: { parts: [] } },
],
},
};
})();
}
return (async function* () {
yield {
type: 'chunk',
value: {
candidates: [
{
finishReason: 'STOP',
content: { parts: [{ text: 'done' }] },
},
],
},
};
})();
});
const scope = await AgentHeadless.create(
'test-agent',
config,
promptConfig,
defaultModelConfig,
defaultRunConfig,
toolConfig,
eventEmitter,
);
await scope.execute(new ContextState());
const writeResults = toolResultEvents.filter(
(event) => event.name === WriteFileTool.Name,
);
// Exactly one write_file invocation should execute — the retried one.
expect(writeResults).toHaveLength(1);
expect(writeResults[0].callId).toBe('call_post_retry');
// The discarded call must never have produced a TOOL_RESULT event.
expect(
toolResultEvents.some((e) => e.callId === 'call_pre_retry'),
).toBe(false);
});Reverse-validated: with 合入前完整跑了一遍验证，全包测试 5896 个用例 + typecheck/build 都干净，没有回归。提一个补测试的建议： 现有的 如果没有 修复本身很扎实，把截断检查前移到 schema 校验之前是对的。 |

…enLM#3590, QwenLM#3505, QwenLM#3467) (#113) * fix: backport upstream trivial bug fixes (QwenLM#3499, QwenLM#3630, QwenLM#3320) Cherry-picked from QwenLM/qwen-code: - QwenLM#3499 fix(core): use empty string instead of null for reasoning-only assistant content. Some OpenAI-compatible providers (e.g. Ollama qwen3.5:9b) reject content: null with HTTP 400 when reasoning_content is also present. Tool-call-only messages keep null per OpenAI spec. - QwenLM#3630 fix(telemetry): switch FileExporter.serialize from JSON.stringify to safeJsonStringify. OTel ReadableSpans hold a BatchSpanProcessor back-reference that forms a cycle and crashed --telemetry-outfile users. - QwenLM#3320 fix(core): cap chokidar depth at 2 in SkillManager and skip .git / special file types. Prevents FD exhaustion when a skill dir contains node_modules etc., which silently broke node-pty I/O. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(core): scope StreamingToolCallParser per-stream (QwenLM#3525) Backports upstream PR QwenLM#3525 + extends the per-stream context to also cover our fork's <think>-tag parser state. Bug: every caller of Config.getContentGenerator() — foreground turns, fork subagents, run_in_background subagents, ACP concurrent Agent calls (after QwenLM#3463) — shared a single OpenAIContentConverter, which held the StreamingToolCallParser as an instance field. Concurrent streams corrupted each other's tool-call buffers, surfacing as NO_RESPONSE_TEXT. Fix: - New ConverterStreamContext interface holds toolCallParser, thinkBuffer, inThinkTag — one per stream. - createStreamContext() factory replaces resetStreamingToolCalls(). - convertOpenAIChunkToGemini(chunk, ctx) and processThinkChunk(chunk, ctx) thread the context through every parser/think-buffer access. - ContentGenerationPipeline.processStreamWithLogging creates one context at stream entry. The error path no longer manually resets — the context is GC'd when the generator unwinds. Our protoInternal recovery-note logic is preserved on the new shape. Note: upstream's follow-up QwenLM#3550 (full stateless converter refactor) is deferred — it's hygiene without a functional bug; QwenLM#3525 alone fixes the concurrency race. Tests: - New createStreamContext describe replaces resetStreamingToolCalls suite - Streaming <think> tests use a per-test context - pipeline.test.ts mock updated to match the new API - pipeline.concurrent.test.ts (from upstream commit 38edd9d) drives two real concurrent streams and asserts neither corrupts the other's tool-call output (positive control: pre-fix, this test fails with exactly the user-reported bug shape).

Call stripThoughtsFromHistory() in handleModelChange() so thought parts are removed before the next request is built for the new model. * fix(core): reject truncated subagent write_file calls (QwenLM#3505) Backport of upstream QwenLM#3505. Propagates MAX_TOKENS truncation from subagent responses into tool requests and rejects truncated edit calls before schema validation can surface misleading missing-parameter errors. Adapted to our fork's coreToolScheduler.ts which already had the truncation rejection block — kept both, dropped the unused clearRetryCountsForTool() call (we don't have that retry-counter machinery yet).

A permission rule with unbalanced parens was silently parsed with specifier: undefined, causing matchesRule to treat it as a catch-all. For deny rules this blocked all commands; for allow rules a typo could silently auto-approve everything. - Adds an invalid flag to PermissionRule - parseRule marks unbalanced-paren rules as invalid - matchesRule short-circuits invalid rules to never match - parseRules / addSession*Rule / addPersistentRule warn on malformed input - listRules filters invalid rules from /permissions UI Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(core): preserve reasoning_content during session resume and active sessions (GH#3579) * test(config): drop fork-incompatible QwenLM#3304 strip-thoughts test The test from upstream QwenLM#3304 backport assumed an in-place qwen-oauth model switch path that our fork doesn't have; the source-side fix in config.ts (stripThoughtsFromHistory call in handleModelChange) is preserved.

This broke GPT-5 / o-series on OpenAI and Azure OpenAI, which require max_completion_tokens and reject max_tokens with a 400 error. Fix: when the user provides samplingParams explicitly, treat it as the complete source of truth for the wire shape and pass its keys through verbatim. No client-injected defaults, no request fallbacks, no hardcoded parameter names. The user describes what the provider wants; the client trusts them. When samplingParams is absent, the historical default behavior (request fallback through temperature/top_p/.../max_tokens plus provider defaults) is preserved unchanged — existing users see no difference. Concretely, users can now set any of: samplingParams: { max_tokens: 4096 } # GPT-4 / Qwen / DeepSeek samplingParams: { max_completion_tokens: 4096 } # GPT-5 / o-series samplingParams: { reasoning_effort: 'medium' } # future knobs without waiting for a qwen-code release that adds model-specific branches.
