Lunny Xiao	91fa0eb9d7	Avoid warning for system setting when start up (#23054) ... Partially fix #23050 After #22294 merged, it always has a warning log like `cannot get context cache` when starting up. This should not affect any real life but it's annoying. This PR will fix the problem. That means when starting up, getting the system settings will not try from the cache but will read from the database directly. --------- Co-authored-by: Lauris BH <lauris@nix.lv>	2023-02-24 18:23:13 +08:00
Lunny Xiao	bd820aa9c5	Add context cache as a request level cache (#22294) ... To avoid duplicated load of the same data in an HTTP request, we can set a context cache to do that. i.e. Some pages may load a user from a database with the same id in different areas on the same page. But the code is hidden in two different deep logic. How should we share the user? As a result of this PR, now if both entry functions accept `context.Context` as the first parameter and we just need to refactor `GetUserByID` to reuse the user from the context cache. Then it will not be loaded twice on an HTTP request. But of course, sometimes we would like to reload an object from the database, that's why `RemoveContextData` is also exposed. The core context cache is here. It defines a new context ```go type cacheContext struct { ctx context.Context data map[any]map[any]any lock sync.RWMutex } var cacheContextKey = struct{}{} func WithCacheContext(ctx context.Context) context.Context { return context.WithValue(ctx, cacheContextKey, &cacheContext{ ctx: ctx, data: make(map[any]map[any]any), }) } ``` Then you can use the below 4 methods to read/write/del the data within the same context. ```go func GetContextData(ctx context.Context, tp, key any) any func SetContextData(ctx context.Context, tp, key, value any) func RemoveContextData(ctx context.Context, tp, key any) func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error) ``` Then let's take a look at how `system.GetString` implement it. ```go func GetSetting(ctx context.Context, key string) (string, error) { return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) { return cache.GetString(genSettingCacheKey(key), func() (string, error) { res, err := GetSettingNoCache(ctx, key) if err != nil { return "", err } return res.SettingValue, nil }) }) } ``` First, it will check if context data include the setting object with the key. If not, it will query from the global cache which may be memory or a Redis cache. If not, it will get the object from the database. In the end, if the object gets from the global cache or database, it will be set into the context cache. An object stored in the context cache will only be destroyed after the context disappeared.	2023-02-15 21:37:34 +08:00
Jason Song	21c91b7dff	Set disable_gravatar/enable_federated_avatar when offline mode is true (#22479) ... When offline mode is true, we should set `disable_gravatar` to `true` and `enable_federated_avatar` to `false` in system settings.	2023-01-17 17:00:19 +02:00
Lunny Xiao	dfd2db5695	Fix set system setting failure once it cached (#22333) ... Unfortunately, #22295 introduced a bug that when set a cached system setting, it will not affect. This PR make sure to remove the cache key when updating a system setting. Fix #22332	2023-01-08 21:22:41 +08:00

Lunny Xiao	a1c30740bb	Fix get system setting bug when enabled redis cache (#22295) ... Fix #22281 In #21621 , `Get[V]` and `Set[V]` has been introduced, so that cache value will be `*Setting`. For memory cache it's OK. But for redis cache, it can only store `string` for the current implementation. This PR revert some of changes of that and just store or return a `string` for system setting.	2023-01-02 00:06:52 +08:00
Lunny Xiao	9c8fc7f677	Fix bug of DisableGravatar default value (#22296) ... #18058 made a mistake. The disableGravatar's default value depends on `OfflineMode`. If it's `true`, then `disableGravatar` is true, otherwise it's `false`. But not opposite. Co-authored-by: KN4CK3R <admin@oldschoolhack.me>	2023-01-01 20:19:23 +08:00

Lunny Xiao	34283a74e8	Allow detect whether it's in a database transaction for a context.Context (#21756) ... Fix #19513 This PR introduce a new db method `InTransaction(context.Context)`, and also builtin check on `db.TxContext` and `db.WithTx`. There is also a new method `db.AutoTx` has been introduced but could be used by other PRs. `WithTx` will always open a new transaction, if a transaction exist in context, return an error. `AutoTx` will try to open a new transaction if no transaction exist in context. That means it will always enter a transaction if there is no error. Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: 6543 <6543@obermui.de>	2022-11-12 21:18:50 +01:00
