📖 PR 背景与需求
问题背景:
多网盘挂载场景下存在三大严重问题:
- 容量显示缺失:首页和管理页面大量显示
-而非容量进度条(#1815, #2633, #2635) - 后台任务强制中断:强刷时超过 1 秒的请求被直接中断,后台探测无法完成并写入缓存
- 缓存一致性混乱:强刷后立即 F5 刷新会返回旧缓存,用户无法区分数据新旧
核心根因:
- Context 过早取消:后台 Goroutine 继承 HTTP 请求的 Context,前端 1 秒超时后框架自动取消,导致跨国高延迟存储的网络请求被
context canceled强制中断 - OneDrive Token 刷新被禁用:
getDrive()传递noRetry=true,导致闲置 1 小时后的账号因401 InvalidAuthenticationToken永久失败 - 缺少显式缓存失效:强刷时未清除旧缓存,后续请求可能返回过期数据
核心需求:
- 解耦 Context,让后台探测独立运行 15 秒并成功落入 30 分钟缓存
- 启用 OneDrive 自动 Token 刷新
- 强刷时显式失效旧缓存,保证数据强一致性
- 添加 Singleflight 并发去重和可配置冷却保护

STYLE组,标记为PRIVATE,避免普通用户误触
⚠️ 需要关注的点
1. Context 取消后资源清理时序 ⚠️ 低优先级
问题位置:
bgCtx, cancel := context.WithTimeout(context.WithoutCancel(ctx), timeoutSec)
go func(dri driver.Driver) {
defer cancel()
details, err := GetStorageDetails(bgCtx, dri, refresh)
// ...
}(d)现状:defer cancel() 确保超时后资源释放。
潜在边界情况:
- 如果 Goroutine 因 panic 中断,
cancel()依然会执行(defer 机制保证) - 但若系统在
defer执行前被强制终止(如 SIGKILL),可能存在极微小的资源泄漏风险
建议:当前实现已足够健壮,无需改动。若追求极致可靠性,可考虑在外层增加 recover() 捕获 panic 并记录日志。
2. lastDoneTimes 内存无限增长 ⚠️ 中等优先级
问题位置:
var (
detailsG singleflight.Group[*model.StorageDetails]
detailsLock sync.RWMutex
lastDoneTimes = make(map[string]int64)
)现状:lastDoneTimes 是全局 map,每个挂载路径记录一个时间戳。
潜在问题:
- 如果用户频繁添加/删除网盘(如临时挂载测试账号),map 会持续增长
- 删除的网盘路径不会从 map 中清理,造成内存泄漏(虽然增长速度极慢)
建议:
- 短期:保持当前实现(实际泄漏量极小,单个条目仅 24 字节)
- 长期:考虑以下方案之一:
- 定期清理超过 N 小时未访问的条目(如每小时清理一次)
- 使用 LRU Cache 限制 map 大小(如最多保留 1000 个条目)
- 在网盘删除时主动清理对应条目(需要监听存储删除事件)
3. 并发写入 lastDoneTimes 的锁粒度 ⚠️ 低优先级
问题位置:
detailsLock.Lock()
lastDoneTimes[mountPath] = time.Now().Unix()
detailsLock.Unlock()现状:使用全局 sync.RWMutex 保护所有网盘的时间戳更新。
分析:
- 当前实现简单清晰,锁竞争概率极低(写操作仅在探测完成时触发)
- 理论上可以用
sync.Map或分片锁优化,但实际收益微乎其微
建议:保持当前实现,无需优化。
4. 配置项读取性能 ⚠️ 极低优先级
问题位置:
func getSettingInt(key string, defaultValue int) int {
if item, err := GetSettingItemByKey(key); err == nil && item != nil {
// ...
}
return defaultValue
}现状:每次调用 GetStorageVirtualFilesWithDetailsByPath 都会读取配置项。
分析:
GetSettingItemByKey通常有缓存机制,性能影响极小- 该函数调用频率不高(仅在用户访问首页/管理页时触发)
建议:无需优化,当前实现清晰易维护。
5. 错误日志覆盖 📝 文档建议
问题位置:
if err != nil {
if !errors.Is(err, errs.NotImplement) && !errors.Is(err, errs.StorageNotInit) {
log.Errorf("failed get %s storage details: %+v", dri.GetStorage().MountPath, err)
}
}现状:已完善记录非预期错误。
建议:在文档或 FAQ 中说明:
- 用户看到此日志时,应检查对应网盘的网络连接、认证状态和配额权限
context.DeadlineExceeded错误说明 15 秒超时不足,可调整storage_details_timeout_seconds

本轮新增 1 个 commit(db74404b),改动文件:internal/op/storage.go、internal/op/storage_details_test.go
新增改动的问题:
- 💡 [P2]
internal/op/storage.go—cleanExpiredLastDoneTimesLocked采用「map 超过 256 项时才触发清理」的惰性策略。若长期稳定运行在 200 个左右挂载点,过期项会一直驻留不被回收。量级很小不影响正确性,是否考虑顺便在InvalidateStorageDetailsState里也做一次轻量清理呢?纯属锦上添花~ - 💡 [P2]
expireThreshold硬编码为86400(1 天)。是否考虑提为包级常量并加一行注释说明单位是秒,可读性会更好一些~
旧问题解决情况:
- ✅ 后台探测 goroutine 缺少 panic 保护 → 已在
GetStorageVirtualFilesWithDetailsByPath的 goroutine 与detailsG.Do内部双层加上recover(),并把 panic 转成 error 返回而非吞掉,处理得比我上轮建议的更完整 - ✅
lastDoneTimes无限增长隐患 → 已通过cleanExpiredLastDoneTimesLocked+ 存储增删时调用InvalidateStorageDetailsState解决 - ✅ 缺少 panic 场景测试 → 已补充
TestGetStorageDetailsPanicRecovery,用mockPanicDriverWithDetails验证驱动 panic 不会击穿进程
🎯 结论:✅ 建议 Approve — 上轮提出的建议项已全部落实且实现质量高于预期,剩余两条均为可选优化。

internal/op/storage.go:539
- Using the normalized
mountPathhere merges a normal mount and its.balancecompanion into one singleflight key.getStoragesByPathintentionally keeps both variants, and those drivers can have different quotas; whichever request wins supplies its result to the other, while the cache already uses the same normalized key. Keep the raw mount path (as before) or include driver identity in this singleflight key.
details, err, _ := detailsG.Do(mountPath, func() (ret *model.StorageDetails, err error) {
internal/op/storage.go:550
- Invalidating the cache/state does not stop an already-running detached probe. If a storage is deleted or updated while this singleflight call is in flight, it can still execute
Cache.SetStorageDetailsafterward and repopulate quota data (andlastDoneTimesbelow) for the removed/old driver; a new storage at the same mount path could then read that result. Associate probes with a storage generation or verify the generation before publishing the result.

大佬们好,这个 PR 已经提交快两个月了,之前审核 Bot 提的几轮优化和建议(包括代数屏障、panic 保护、缓存失效和配置项清理等)都全部改好了,今天我也刚把分支 rebase 到最新的 main 解决了冲突,单测全绿。想问下目前合并这块还需要补充哪些修改吗?如果没问题的话辛苦有空帮忙 review 看下能不能合一下哈,感谢! |
|
InvalidateStorageDetailsState() 直接 delete(cacheVersions, actual) 会把 generation 重置成 0。 refresh 虽然用了单独的 :refresh singleflight key,但 refresh 发生后,新来的普通请求仍可能 join refresh 前那个正在执行的普通 flight。旧 flight 最终不会写缓存,但它的结果仍会直接返回给调用者,所以强刷后的短时间内还是可能看到旧数据。 |
- Unify capacity identity and generation state, including balance mounts. - Coalesce overlapping refreshes and post-refresh reads, and detach shared probe deadlines from caller cancellation. - Gate capacity admission during initialization, update, disable, and deletion; reject stale publications and failed initialization. - Add deterministic concurrency, deadline, cancellation, cache, and lifecycle regressions; restore test settings.

@jyxjjj @PIKACHUIM 两位大佬好,打扰啦~想温和 ping 一下这个 PR 😊 上次反馈的 generation 单调递增和 singleflight 按路径+版本隔离的问题都已经修好补齐单测了,这段时间我自己线上跑下来也很稳。另外配套的前端 PR (OpenListTeam/OpenList-Frontend#641) 我刚也顺手 rebase 到了最新的 main 分支消掉了字典冲突,目前两边都是零冲突状态。 看看最近两位哪位有空的时候能不能帮忙再 review 一下?如果还有哪里需要调整的随时说,我这边马上改,辛苦啦!🙏 |

看了最新的 bc3d442,上次提的 generation 单调递增和按完整挂载路径 + generation 隔离 flight 都已经改了,也补了对应回归测试。还有两处要改下:
这里要区分“尚未修改驱动就失败”和“驱动重初始化失败”。写库失败时应恢复旧驱动的容量查询资格,并补一个失败后仍能查询旧容量的测试。
需要保留旧对象不可查询的保护,同时避免用全局 map 永久强引用已退役驱动。路径 generation 仍应保持单调递增,不能靠归零解决。建议补上反复禁用、启用和删除后的对象保留检查。 这次做了静态审核,没有独立运行单测或 race 检查。 另外,PR 描述新增了两个配置项,但“修改配置”仍未勾选。最新提交也有 Codex 的 Co-authored-by,AI 使用声明目前只列了 Gemini,这两处一起同步下。 Reviewed or refined by GPT-6.1-Sol Medium |

…tings, prune states, abandon hung probes - DisableStorage: only mark the in-memory driver DISABLED once the disable completes; a failed Drop or DB update no longer leaves an enabled, mounted storage reporting "disabled". - Clamp storage_details_timeout_seconds to [1, 600] (<=0 falls back to 15) and storage_details_cooldown_seconds to [0, 86400]. - Draw generations from a process-wide sequence so idle per-mount states can be deleted safely; prune states idle for 24h (throttled to once per hour) instead of only zeroing lastDone. - Callers stop waiting timeout+2s after joining a flight and supersede it, so a driver that ignores context cancellation can no longer wedge refreshes for its mount until the next storage change.

…neDrive token retry - Probe now returns at its own deadline even when a driver ignores context cancellation, so a hung GetDetails cannot hold the flight or the mount's refresh barrier open. This replaces the caller-side abandon timer. - UpdateStorage: when Drop fails, roll the database row back, keep the driver registered at its old mount path, and report the failure as its status instead of leaving the database ahead of an orphaned driver. - DisableStorage: a failed Drop or DB update reports the error as status rather than DISABLED; a successful disable always ends in DISABLED. - Details listing: a recovered panic now delivers nil instead of making the caller wait for its 1s timeout. - OneDrive / OneDrive APP: retry an InvalidAuthenticationToken request at most once after refreshing, so getDrive cannot recurse indefinitely. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01U5btuswaVrY7Lp7FWWVEHh
Supersedes the previous commits on this branch with a smaller design and merges the current main. Resulting change set: - Probes run detached from the caller's cancellation, bounded by storage_details_timeout_seconds (default 15, clamped to 1..600), and return at that deadline even if the driver ignores it. Driver panics become errors. - Each mount path has a generation from a process-wide sequence. Init, update, disable and delete mark the path as changing (no probes admitted) and drop its state, so a probe started earlier can no longer publish. - Only the driver currently registered at a mount path may report its capacity; disabled, deleted or replaced driver objects get StorageNotInit. The details code no longer changes storage status. - Refresh bypasses the cache and joins a probe that is already running. storage_details_cooldown_seconds (default 0 = off, max 86400) serves refreshes from the cache for that long after the last successful probe. - The details cache is keyed by the full mount path, matching the probe key, so balanced storages no longer overwrite each other's capacity. The OneDrive token change moved to its own branch, fix/onedrive-drive-token-retry.

Changes
storage_details_timeout_seconds; they return at that deadline even if the driver ignores it. Driver panics become errors.StorageNotInit. The details code does not change storage status.storage_details_cooldown_seconds(off by default) serves refreshes from the cache for that long after the last successful probe, to avoid hitting drive API rate limits./a,/a.balance1) no longer overwrite each other's capacity.New settings (group: Style, private)

改动
storage_details_timeout_seconds限时;即使驱动不响应取消,也会在超时时返回。驱动 panic 会转为错误。StorageNotInit。容量逻辑不会修改存储状态。storage_details_cooldown_seconds(默认关闭)在上次成功探测后的这段时间内,刷新直接返回缓存,避免触发网盘 API 限流。/a、/a.balance1)不再互相覆盖容量。新增设置(分组:样式,私有)
