Kernel: Add the actual UID by parsing the UID in /data/user_de/ #2759

ShirkNeko · 2025-09-15T09:33:44Z

获取活跃用户UserID列表
通过 /data/user_de/{userid}/[package] 解析对应用户应用的UID
弃用通过不稳定的 packages.list 获取

…[app] directory Prioritize retrieving the application UID from /data/user_de. If this fails, fall back to retrieving it from packages.list. Fix unstable application UID acquisition Signed-off-by: ShirkNeko <[email protected]>

Enhance scan support for active users in /data/user_de Signed-off-by: ShirkNeko <[email protected]>

- Remove the deprecated USER_DATA_LEGACY_BASE_PATH path -Increase the size of USER_DATA_PATH_LEN to 384

…ser ID range.

提交 efb0c44 以后，为多用户扫描添加可选开关

默认始终只扫描主用户的应用UID
在管理器设置中添加 扫描所有用户 开关（默认为关闭）
打开 扫描所有用户开关 将扫描 /data/user_de 以获取所有用户并扫描所有多用户应用 UID

aviraxp · 2025-09-15T13:08:17Z

建议不添加开关，刚看了下，全部扫一个用户的所有应用其实几十毫秒就能完成，没必要增加复杂性

看术哥怎么说吧，对于内核来说确实越小的开销越好

我也不建议加开关。之前 comment 里面的 Optional 指的是对开发者而言的，如果想做可以加上，不想做就不做；并非把这个选择权给用户，用户看到这个开关可能会很懵逼。

我觉得直接在内核中直接遍历/data是否会导致部分机型在解析时如果遇到了加密或挂载状态有概率会导致内核死锁

因为它是一个动态目录，而不是像packages.list一样是一个静态文件
