* Remove the service worker (#25010)silverwind2023-05-311-1/+0
| | | | | | | | | | | | | It's been disabled by default since 1.17 (https://github.com/go-gitea/gitea/pull/18914), and it never really delivered any benefit except being another cache layer that has its own unsolved invalidation issues. HTTP cache works, we don't need two cache layers at the browser for assets. ## :warning: BREAKING You can remove the config `[ui].USE_SERVICE_WORKER` from your `app.ini` now.
* Improve template system and panic recovery (#24461)wxiaoguang2023-05-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Partially for #24457 Major changes: 1. The old `signedUserNameStringPointerKey` is quite hacky, use `ctx.Data[SignedUser]` instead 2. Move duplicate code from `Contexter` to `CommonTemplateContextData` 3. Remove incorrect copying&pasting code `ctx.Data["Err_Password"] = true` in API handlers 4. Use one unique `RenderPanicErrorPage` for panic error page rendering 5. Move `stripSlashesMiddleware` to be the first middleware 6. Install global panic recovery handler, it works for both `install` and `web` 7. Make `500.tmpl` only depend minimal template functions/variables, avoid triggering new panics Screenshot: <details> ![image](https://user-images.githubusercontent.com/2114189/235444895-cecbabb8-e7dc-4360-a31c-b982d11946a7.png) </details>

* Introduce GitHub markdown editor, keep EasyMDE as fallback (#23876)wxiaoguang2023-04-031-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first step of the plan * #23290 Thanks to @silverwind for the first try in #15394 . Close #10729 and a lot of related issues. The EasyMDE is not removed, now it works as a fallback, users can switch between these two editors.

* Use a general approch to improve a11y for all checkboxes and dropdowns. (#23542)wxiaoguang2023-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR follows #22599 and #23450 The major improvements: 1. The `aria-*.js` are totally transparent now, no need to call `attachDropdownAria` explicitly anymore. * It hooks the `$.fn.checkbox` and `$.fn.dropdown`, then our patch works. * It makes all dynamically generated checkbox/dropdown work with a11y without any change * eg: the `conversation.find('.dropdown').dropdown();` in `repo-diff.js` 2. Since it's totally transparent now, it could be easier to modify or remove in the future. 3. It handles all selection labels as well (by onLabelCreate), so it supports "multiple selection dropdown" now. * It partially completes one of my TODOs: `TODO: multiple selection is not supported yet.` 4. The code structure is clearer, code blocks are splitted into different functions. * The old `attachOneDropdownAria` was splitted into separate functions. * It makes it easier to add more fine tunes in the future, and co-work with contributors. 6. The code logic is similar as before, only two new parts: 1. the `ariaCheckboxFn` and `ariaDropdownFn` functions 2. the `onLabelCreate` and `updateSelectionLabel` functions In `aria-dropdown.js` I had to mix jQuery and Vanilla JS somewhat, I think the code is still understandable, otherwise the code would be much more complex to read. Thanks to fsologureng for the idea about "improving the 'delete icon' with aria attributes". If there is anything unclear or incorrect, feel free to ask and discuss, or propose new PRs for it.
* Introduce customized HTML elements, fix incorrect AppUrl usages in templates ↵wxiaoguang2023-02-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#22861) This PR follows: * #21986 * #22831 This PR also introduce customized HTML elements, which would also help problems like: * #17760 * #21429 * #21440 With customized HTML elements, there won't be any load-search-replace operations, and it can avoid page flicking (which @silverwind cares a lot). Browser support: https://developer.mozilla.org/en-US/docs/Web/API/Window/customElements # FAQ ## Why the component has the prefix? As usual, I would strongly suggest to add prefixes for our own/private names. The dedicated prefix will avoid conflicts in the future, and it makes it easier to introduce various 3rd components, like GitHub's `relative-time` component. If there is no prefix, it's impossible to introduce another public component with the same name in the future. ## Why the `custcomp.js` is loaded before HTML body? The `index.js` is after HTML body. Customized components must be registered before the content loading. Otherwise there would be still some flicking. `custcomp.js` should have its own dependencies and should be very light, so it won't affect the page loading time too much. ## Why use `data-url` attribute but not use the `textContent`? According to the standard, the `connectedCallback` occurs on the tag-opening moment. The element's children are not ready yet. ## Why not use `{{.GuessCurrentOrigin $.ctx ...}}` to let backend decide the absolute URL? It's difficult for backend to guess the correct protocol(scheme) correctly with zero configuration. Generating the absolute URL from frontend can guarantee that the URL is 100% correct -- since the user is visiting it. # Screenshot <details> ![image](https://user-images.githubusercontent.com/2114189/218256757-a267c8ba-3108-4755-9ae5-329f1b08f615.png) </details>
* Add context cache as a request level cache (#22294)Lunny Xiao2023-02-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Remove useless `appVer` from JS `window.config` (#21445)wxiaoguang2022-10-141-1/+0
| | | | The only usage of `appVer` was in serviceworker.js, while indeed it needs the asset version.
* Add whitespace removal inside template curly brackes (#20853)silverwind2022-08-251-6/+6

* Enable contenthash in filename for dynamic assets (#20813)silverwind2022-08-231-0/+1
| | | | | This should solve the main problem of dynamic assets getting stale after a version upgrade. Everything not affected will use query-string based cache busting, which includes files loaded via HTML or worker scripts.
* Fix eslint parsing errors, remove eslint-plugin-html (#20323)silverwind2022-07-151-1/+0
| | | | | | | | | | | Introduce a separate .eslintrc in the Vue components folder to selectively enable vue-eslint-parser there, so that the rest of the files can use eslint's core parser which can deal with hashbangs. The fact that the eslint-disable comments worked in HTML was a unintended side-effect of the files being parsed via vue-eslint-parser, so I had to disable the parsing of these files in .eslintrc.yaml to make it work, and finally decided to remove eslint-plugin-html as it causes more issues than it solves.
* Refactor `i18n` to `locale` (#20153)Gusted2022-06-271-4/+4
| | | | | | | | | | | * Refactor `i18n` to `locale` - Currently we're using the `i18n` variable naming for the `locale` struct. This contains locale's specific information and cannot be used for general i18n purpose, therefore refactoring it to `locale` makes more sense. - Ref: https://github.com/go-gitea/gitea/pull/20096#discussion_r906699200 * Update routers/install/install.go
* Show messages for users if the ROOT_URL is wrong, show JavaScript errors ↵wxiaoguang2022-03-301-0/+49
(#18971) * ROOT_URL issues: some users did wrong to there app.ini config, then: * The assets can not be loaded (AppSubUrl != "" and users try to access http://host:3000/) *The ROOT_URL is wrong, then many URLs in Gitea are broken. Now Gitea show enough information to users. * JavaScript error issues, there are many users affected by JavaScript errors, some are caused by frontend bugs, some are caused by broken customized templates. If these JS errors can be found at first time, then maintainers do not need to ask about how bug occurs again and again. * Some people like to modify the `head.tmpl`, so we separate the script part to `head_script.tmpl`, then it's much safer. * use specialized CSS class "js-global-error", end users still have a chance to hide error messages by customized CSS styles.
