RPM、冷却剩余、禁用原因（如"key 被拒（401），本会话已停用"）。 + - "测试连接"改为对列表逐个或选中项测试。 +- `src/lib/api.ts`：`testTranslationSettings`/`listTranslationModels` 加 `providerId` 参数；新增 `getTranslationPoolStatus()`。 +- `src/lib/types.ts`：`ProviderConfig`、`PoolStatus` 类型；`TranslationSettings` 加 `providers`/`batchMaxChars`。 +- i18n：`en.json`/`zh-CN.json` 起，10 个语言文件同步新增/删除 `pacing*` 与 provider 相关 key（照现有 key 命名风格）。 +-

---- - -## 第 3 期：设置页 UI + 状态展示 + i18n - -- `src/components/settings/translation-settings.tsx`： - - 删除 `PACING_FIELDS` 三旋钮（`:84-106`、fingerprint `:76-78`、init `:183-185`），替换为"RPM 上限（每供应商）"+"合批字符上限（全局）"。 - - 新增供应商列表编辑器：每行 name/base_url/api_key/model/api_format/enabled + 删除按钮，"添加供应商"按钮；每行的"测试连接"和"获取模型列表"传该行的 `provider_id`。单供应商时 UI 形态与现在基本一致（列表只有一行）。 - - 新增每供应商状态徽标区（轮询 `translation_pool_status`，10s 刷新）：当前 RPM、冷却剩余、禁用原因（如"key 被拒（401），本会话已停用"）。 - - "测试连接"改为对列表逐个或选中项测试。 -- `src/lib/api.ts`：`testTranslationSettings`/`listTranslationModels` 加 `providerId` 参数；新增 `getTranslationPoolStatus()`。 -- `src/lib/types.ts`：`ProviderConfig`、`PoolStatus` 类型；`TranslationSettings` 加 `providers`/`batchMaxChars`。 -- i18n：`en.json`/`zh-CN.json` 起，10 个语言文件同步新增/删除 `pacing*` 与 provider 相关 key（照现有 key 命名风格）。 -- 测试：`translation-settings.test.tsx` 现有用例改写到新 UI（列表增删、保存 payload 含 providers、旋钮消失）；新增 AIMD/池/合批的前后端单测（见各期）。 - ---- - -## 验证 - -- 后端：`cargo check`、`cargo test --features test-utils`、`cargo clippy --all-targets --features test-utils -- -D warnings`；`--no-default-features --bin codeg-server` 三件套同样跑。 -- 前端：`pnpm eslint .`、`pnpm test`、`pnpm build`。 -

The soft in-flight deadline (30 s) now records a SlowInflight event the moment the wait becomes reader-visible and halves the provider's rate on the spot, so later chunks rotate elsewhere while the slow request is still out. The event weighs half on stability, like a 429 — nothing failed, but the lane is being held — and is deliberately excluded from the speed window, where the eventual reply records the true round trip (counting both would double-punish one ask). Quality never hears about it: no reply was judged. --- src-tauri/src/translation/client.rs | 39 +++++++++++++++++- src-tauri/src/translation/health.rs | 44 +++++++++++++++++++- src-tauri/src/translation/metrics.rs | 11 +++++ src-tauri/src/translation/pool.rs | 61 +++++++++++++++++++++++++++- 4 files changed, 151 insertions(+), 4 deletions(-) diff --git a/src-tauri/src/translation/client.rs b/src-tauri/src/translation/client.rs index 2f2dce2a00..0e1f2f14d7 100644 --- a/src-tauri/src/translation/client.rs +++ b/src-tauri/src/translation/client.rs @@ -46,6 +46,13 @@ const CONNECT_TIMEOUT: Duration = Duration::from_secs(10); /// spend tens of seconds *thinking* about even a short translation, so a flat /// 60 s reads as "endpoint broken" when the endpoint is merely slow. const READ_TIMEOUT: Duration = Duration::from_secs(120); +/// How long a request may stay in flight before the pool treats the provider +/// as "slow right now": the health window learns at this mark instead of when +/// the reply lands, and the rate halves so later chunks rotate elsewhere. +/// Deliberately far below READ_TIMEOUT — the hard timeout judges a broken +/// endpoint, this judges a reader-visible wait — and deliberately generous: +/// reasoning relays routinely take 10-20 s on a normal batch. +const SLOW_INFLIGHT: Duration = Duration::from_secs(30); /// Well under the ~30-60 s idle cutoff CDNs apply to keep-alive connections: /// a pooled connection older than this is evicted instead of failing the next /// request the instant it is reused. @@ -444,7 +451,37 @@ async fn translate_one( for (name, value) in auth_headers(format, &provider.api_key) { request = request.header(name, value); } - let outcome = request.json(&body).send().await; + // The soft in-flight deadline: the request keeps waiting for its full + // budget, but at the mark the pool already learns the provider is + // slow — an endpoint answering in 90 s held a Background-lane slot + // for the whole round trip while every queued chunk waited on it, and + // the health window only heard about it when the reply landed. + let pending = request.json(&body).send(); + tokio::pin!(pending); + let slow_mark = tokio::time::Instant::now() + SLOW_INFLIGHT; + let mut slow_reported = false; + let outcome = loop { + tokio::select! { + biased; + response = &mut pending => break response, + _ = tokio::time::sleep_until(slow_mark), if !slow_reported => { + slow_reported = true; + let elapsed = started.elapsed().as_millis() as u64; + tracing::warn!( + "[translation] request to {} still in flight after {}ms — \ + halving its rate for the remainder of the wait", + picked.id(), + elapsed + ); + translation_metrics().record_attempt( + picked.id(), + ProviderEventKind::SlowInflight, + elapsed, + ); + picked.report_slow_inflight(); + } + } + }; last_latency_ms = started.elapsed().as_millis() as u64; let latency = last_latency_ms; diff --git a/src-tauri/src/translation/health.rs b/src-tauri/src/translation/health.rs index 1c0adbe988..bf0c862d7a 100644 --- a/src-tauri/src/translation/health.rs +++ b/src-tauri/src/translation/health.rs @@ -50,7 +50,9 @@ const QUALITY_REJECT_ZERO: f64 = 0.4; /// Stability maps the weighted failure rate onto 1.0 → 0.0.

Two fixes plus a race found while reproducing: - Giving up a gap now stitches the raw source as an identity piece (the settle flush's whitespace stitch, extended to give-ups): the chain stays whole and the raw lead renders ahead of the translated rest. - A segment already written in the display language (Han-dominant against a zh target, judged on settings.targetLang ?? uiLocale) lands as an identity piece without a request — the echo it would get back IS the correct translation. - The settle flush now also holds off while any in-flight SUBSEGMENT of its gap is on the wire: a flush request sent past the fallback landings could be refused and given up, stitching the whole span raw and burying the subsegment's translation under an identity piece the chain can never see past. This replaces the accepted one-shot double-spend: the flush re-runs on the landing and spends one request, not two. --- .../use-streaming-translated-text.test.tsx | 101 ++++++++++++++--- src/hooks/use-streaming-translated-text.ts | 104 +++++++++++++++--- src/lib/translation.test.ts | 36 ++++++ src/lib/translation.ts | 26 +++++ 4 files changed, 237 insertions(+), 30 deletions(-) diff --git a/src/hooks/use-streaming-translated-text.test.tsx b/src/hooks/use-streaming-translated-text.test.tsx index 96e862bdeb..d2bd16e0a6 100644 --- a/src/hooks/use-streaming-translated-text.test.tsx +++ b/src/hooks/use-streaming-translated-text.test.tsx @@ -427,13 +427,13 @@ describe("useStreamingTranslatedText", () => { expect(mocks.translate).toHaveBeenCalledTimes(1) expect(unwrap(mocks.translate.mock.calls[0][0][0])).toBe("[1] u1\n\n[2] u2") - // Settle while the group request is still in flight: the flush cannot - // know its results yet, so it requests from the untranslated prefix — - // the whole text (the accepted one-shot double-spend). + // Settle while the group request is still in flight: the flush holds off + // (the in-flight subsegments overlap this gap, and a flush sent past them + // that got refused would stitch the whole block raw over their landings), + // then re-runs once the landing re-opens the boundary. rerender({ text: fullText, isStreaming: false }) await flush() - expect(mocks.translate).toHaveBeenCalledTimes(2) - expect(unwrap(mocks.translate.mock.calls[1][0][0])).toBe(fullText) + expect(mocks.translate).toHaveBeenCalledTimes(1) // The group lands and moves the translated prefix past the remainder's // start.

Providers can now be parked and revived explicitly, and the auto-cooldown is a setting instead of a hardcoded session exile: - Three new commands (and web routes): provider_reset, provider_disable, provider_cooldown. The settings page renders a Ban/Timer/RotateCcw action per provider row plus a header strategy popover. - Consecutive failures (429s and hard errors alike) now trigger a bounded cooldown — failure_threshold (default 3) and cooldown_seconds (default 60) live in settings, read per request so a mid-flight edit cannot rewrite the thresholds under an in-flight pick. - Two lane concurrency caps: priority_max_concurrent for prose the reader is waiting on, background_max_concurrent for thinking-block translation so it cannot crowd out the priority lane on a small endpoint. - translate_body setting (default true) so reply-prose translation can be turned off while thinking blocks keep theirs. - Saves broadcast translation-settings-changed to every open frontend; other windows re-fetch instead of keeping the mount-time snapshot. - New i18n keys across all 10 locales; settings tests cover the new UI surface. Housekeeping: gate the Windows resource link directive behind tauri-runtime (server-mode test exes need no manifest), ignore security-scan artifacts. --- .gitignore | 6 + src-tauri/src/bin/codeg_server.rs | 26 +- src-tauri/src/commands/translation.rs | 96 +- src-tauri/src/lib.rs | 59 +- src-tauri/src/translation/aimd.rs | 42 +- src-tauri/src/translation/client.rs | 712 +++++++++-- src-tauri/src/translation/health.rs | 64 +- src-tauri/src/translation/metrics.rs | 457 ++++++- src-tauri/src/translation/mod.rs | 70 +- src-tauri/src/translation/pool.rs | 751 +++++++++-- src-tauri/src/translation/settings.rs | 324 ++++- src-tauri/src/web/handlers/translation.rs | 62 +- src-tauri/src/web/router.rs | 32 +- .../message/content-parts-renderer.tsx | 5 +- .../settings/translation-settings.test.tsx | 937 +++++++++++++- .../settings/translation-settings.tsx | 1128 ++++++++++++++--- .../use-streaming-translated-text.test.tsx | 162 +++ src/hooks/use-translated-text.test.ts | 221 +++- src/hooks/use-translated-text.ts | 47 +- src/i18n/messages/ar.json | 41 + src/i18n/messages/de.json | 41 + src/i18n/messages/en.json | 41 + src/i18n/messages/es.json | 41 + src/i18n/messages/fr.json | 41 + src/i18n/messages/ja.json | 41 + src/i18n/messages/ko.json | 41 + src/i18n/messages/pt.json | 41 + src/i18n/messages/zh-CN.json | 41 + src/i18n/messages/zh-TW.json | 41 + src/lib/api.ts | 32 + src/lib/types.ts | 55 + 31 files changed, 5081 insertions(+), 617 deletions(-) diff --git a/.gitignore b/.gitignore index 718d4d9101..7062a61e74 100644 --- a/.gitignore +++ b/.gitignore @@ -68,3 +68,9 @@ src-tauri/binaries/ src-tauri/runtest.* src-tauri/translation_out.txt src/probe.test.ts + +# security-scan and tooling artifacts (regenerated on every scan) +.mimosa/ +src-tauri/.mimosa/ +.magi/ +bash.exe.stackdump diff --git a/src-tauri/src/bin/codeg_server.rs b/src-tauri/src/bin/codeg_server.rs index 3b28000f98..0e26b80346 100644 --- a/src-tauri/src/bin/codeg_server.rs +++ b/src-tauri/src/bin/codeg_server.rs @@ -213,9 +213,7 @@ async fn async_main() -> ExitCode { // bearer credential and must never enter the durable log files or the // in-app log viewer. `eprintln!` bypasses the tracing sinks (file + // ring buffer); only the local terminal / Docker stderr sees it. - eprintln!( - "[SERVER] No CODEG_TOKEN set; generated an access token (persisted): {token}" - ); + eprintln!("[SERVER] No CODEG_TOKEN set; generated an access token (persisted): {token}"); eprintln!("[SERVER] Pin your own by setting the CODEG_TOKEN environment variable."); } @@ -267,6 +265,20 @@ async fn async_main() -> ExitCode { })); } + // Push translation-settings changes to connected clients: hooks beyond + // the window that saved re-fetch their snapshot on this event instead of + // keeping the mount-time copy. + { + let emitter = emitter.clone(); + codeg_lib::translation::settings::on_settings_change(Arc::new(move || { + codeg_lib::web::event_bridge::emit_event( + &emitter, + "translation-settings-changed", + serde_json::json!({}), + ); + })); + } + // Build AppState let pet_state_handle = codeg_lib::pet_state_mapper::new_pet_state_handle(); let connection_manager = codeg_lib::app_state::default_connection_manager(); @@ -581,9 +593,11 @@ async fn async_main() -> ExitCode { // Publish runtime state so the settings page (served by us) shows // the truth — running on `actual_port` with this token — instead of // the placeholder "stopped" that triggers the stale-port banner. - state - .web_server_state - .mark_externally_running(advertised_host.clone(), actual_port, token.clone()); + state.web_server_state.mark_externally_running( + advertised_host.clone(), + actual_port, + token.clone(), + ); let addresses = addresses_for_bind(&advertised_host, actual_port); // Token on stderr ONLY (bearer credential — keep it out of the log files diff --git a/src-tauri/src/commands/translation.rs b/src-tauri/src/commands/translation.rs index 5667a50bd0..7cd8092567 100644 --- a/src-tauri/src/commands/translation.rs +++ b/src-tauri/src/commands/translation.rs @@ -23,11 +23,19 @@ pub async fn translation_get_settings_core( } /// Validate and persist.
