Since `modules/context` has to depend on `models` and many other
packages, it should be moved from `modules/context` to
`services/context` according to design principles. There is no logic
code change on this PR, only move packages.
- Move `code.gitea.io/gitea/modules/context` to
`code.gitea.io/gitea/services/context`
- Move `code.gitea.io/gitea/modules/contexttest` to
`code.gitea.io/gitea/services/contexttest` because of depending on
context
- Move `code.gitea.io/gitea/modules/upload` to
`code.gitea.io/gitea/services/context/upload` because of depending on
context

Fixes an admin api bug related to `user.LoginSource`
Fixed `/user/emails` response not identical to GitHub api
This PR unifies the user update methods. The goal is to keep the logic
only at one place (having audit logs in mind). For example, do the
password checks only in one method not everywhere a password is updated.
After that PR is merged, the user creation should be next.
- Closes https://github.com/go-gitea/gitea/issues/28880
This change introduces htmx with the hope we could use it to make Gitea
more reactive while keeping our "HTML rendered on the server" approach.
- Add `htmx.js` that imports `htmx.org` and initializes error toasts
- Place `hx-headers='{"x-csrf-token": "{{.CsrfToken}}"}'` on the
`<body>` tag so every request that htmx sends is authenticated
- Place `hx-swap="outerHTML"` on the `<body>` tag so the response of
each htmx request replaces the tag it targets (as opposed to its inner
content)
- Place `hx-push-url="false"` on the `<body>` tag so no changes to the
URL happen in `<form>` tags
- Add the `is-loading` class during request
### Error toasts in action
## Don't do a full page load when clicking the subscribe button
- Refactor the form around the subscribe button into its own template
- Use htmx to perform the form submission
- `hx-boost="true"` to prevent the default form submission behavior of a
full page load
- `hx-sync="this:replace"` to replace the current request (in case the
button is clicked again before the response is returned)
- `hx-target="this"` to replace the form tag with the new form tag
- Change the backend response to return a `<form>` tag instead of a
redirect to the issue page
### Before
### After
## Don't do a full page load when clicking the follow button
- Use htmx to perform the button request
- `hx-post="{{.ContextUser.HomeLink}}?action=follow"` to send a POST
request to follow the user
- `hx-target="#profile-avatar-card"` to target the card div for
replacement
- `hx-indicator="#profile-avatar-card"` to place the loading indicator
on the card
- Change the backend response to return a `<div>` tag (the card) instead
of a redirect to the user page

Renames it to `ENABLED` to be consistent with other settings and
deprecates it.
I believe this change is necessary because other setting groups such as
`attachment`, `cors`, `mailer`, etc. have an `ENABLED` setting, but
`oauth2` is the only one with an `ENABLE` setting, which could cause
confusion for users.
This is no longer a breaking change because `ENABLE` has been set as
deprecated and as an alias to `ENABLED`.
- Use htmx to perform the button request
- `hx-headers='{"x-csrf-token": "{{.CsrfToken}}"}'` to authenticate (we
should probably learn to reuse this)
- `hx-post="{{.ContextUser.HomeLink}}?action=follow"` to send a POST
request to follow the user
- `hx-target="#profile-avatar-card"` to target the card div for
replacement
- `hx-swap="outerHTML"` to replace the card (as opposed to its inner
content) with the new card that shows the new follower count and button
color
- Change the backend response to return a `<div>` tag (the card) instead
of a redirect to the user page

Fixes#26548
This PR refactors the rendering of markup links. The old code uses
`strings.Replace` to change some urls while the new code uses more
context to decide which link should be generated.
The added tests should ensure the same output for the old and new
behaviour (besides the bug).
We may need to refactor the rendering a bit more to make it clear how
the different helper methods render the input string. There are lots of
options (resolve links / images / mentions / git hashes / emojis / ...)
but you don't really know what helper uses which options. For example,
we currently support images in the user description which should not be
allowed I think:

<summary>Profile</summary>

fix#28436.
the doc https://docs.gitea.com/usage/profile-readme maybe also need to
be updated to tell that
the main branch is necessary,which means the following three conditions
should be satisfied:
- repo: **.profile**
- branch: **[default branch]**
- markdown: **README.md**
Nowadays, cache will be used on almost everywhere of Gitea and it cannot
be disabled, otherwise some features will become unaviable.
Then I think we can just remove the option for cache enable. That means
cache cannot be disabled.
But of course, we can still use cache configuration to set how should
Gitea use the cache.
It will fix#28268 .

## ⚠️ BREAKING ⚠️
But need to give up some features:
<img width="1312" alt="image"
src="https://github.com/go-gitea/gitea/assets/9418365/281c0d51-0e7d-473f-bbed-216e2f645610">
However, such abandonment may fix#28055 .
## Backgroud
When the user switches the dashboard context to an org, it means they
want to search issues in the repos that belong to the org. However, when
they switch to themselves, it means all repos they can access because
they may have created an issue in a public repo that they don't own.
<img width="286" alt="image"
src="https://github.com/go-gitea/gitea/assets/9418365/182dcd5b-1c20-4725-93af-96e8dfae5b97">
It's a confusing design. Think about this: What does "In your
repositories" mean when the user switches to an org? Repos belong to the
user or the org?
Whatever, it has been broken by #26012 and its following PRs. After the
PR, it searches for issues in repos that the dashboard context user owns
or has been explicitly granted access to, so it causes #28268.
## How to fix it
It's not really difficult to fix it. Just extend the repo scope to
search issues when the dashboard context user is the doer. Since the
user may create issues or be mentioned in any public repo, we can just
set `AllPublic` to true, which is already supported by indexers. The DB
condition will also support it in this PR.
But the real difficulty is how to count the search results grouped by
repos. It's something like "search issues with this keyword and those
filters, and return the total number and the top results. **Then, group
all of them by repo and return the counts of each group.**"
<img width="314" alt="image"
src="https://github.com/go-gitea/gitea/assets/9418365/5206eb20-f8f5-49b9-b45a-1be2fcf679f4">
Before #26012, it was being done in the DB, but it caused the results to
be incomplete (see the description of #26012).
And to keep this, #26012 implement it in an inefficient way, just count
the issues by repo one by one, so it cannot work when `AllPublic` is
true because it's almost impossible to do this for all public repos.
1bfcdeef4c/modules/indexer/issues/indexer.go (L318-L338)
## Give up unnecessary features
We may can resovle `TODO: use "group by" of the indexer engines to
implement it`, I'm sure it can be done with Elasticsearch, but IIRC,
Bleve and Meilisearch don't support "group by".
And the real question is, does it worth it? Why should we need to know
the counts grouped by repos?
Let me show you my search dashboard on gitea.com.
<img width="1304" alt="image"
src="https://github.com/go-gitea/gitea/assets/9418365/2bca2d46-6c71-4de1-94cb-0c9af27c62ff">
I never think the long repo list helps anything.
And if we agree to abandon it, things will be much easier. That is this
PR.
## TODO
I know it's important to filter by repos when searching issues. However,
it shouldn't be the way we have it now. It could be implemented like
this.
<img width="1316" alt="image"
src="https://github.com/go-gitea/gitea/assets/9418365/99ee5f21-cbb5-4dfe-914d-cb796cb79fbe">
The indexers support it well now, but it requires some frontend work,
which I'm not good at. So, I think someone could help do that in another
PR and merge this one to fix the bug first.
Or please block this PR and help to complete it.
Finally, "Switch dashboard context" is also a design that needs
improvement. In my opinion, it can be accomplished by adding filtering
conditions instead of "switching".
The steps to reproduce it.
First, create a new oauth2 source.
Then, a user login with this oauth2 source.
Disable the oauth2 source.
Visit users -> settings -> security, 500 will be displayed.
This is because this page only load active Oauth2 sources but not all
Oauth2 sources.
Fix nil access for inactive auth sources.
> Render failed, failed to render template:
user/settings/security/security, error: template error:
builtin(static):user/settings/security/accountlinks:32:20 : executing
"user/settings/security/accountlinks" at <$providerData.IconHTML>: nil
pointer evaluating oauth2.Provider.IconHTML
Code tries to access the auth source of an `ExternalLoginUser` but the
list contains only the active auth sources.
This PR reduces the complexity of the system setting system.
It only needs one line to introduce a new option, and the option can be
used anywhere out-of-box.
It is still high-performant (and more performant) because the config
values are cached in the config system.
This PR removed `unittest.MainTest` the second parameter
`TestOptions.GiteaRoot`. Now it detects the root directory by current
working directory.

Beginning since 2af30f715e, Gitea has a
500 error when visiting a user profile with `?tab=overview` in the URL
when the user doesn't have a `.profile/README.md`, because the backend
code assumes that if the tab is overview a profile repository must
exist, and checks that the repository is nil aren't done.
In this PR I treat `?tab=overview` the same as if no tab is set in the
URL, which corrects this behaviour- Now, when visiting `?tab=overview`,
if `.profile/README.md` exists on that user's profile it'll show that as
it should, otherwise it'll show the repositories tab.

Unfortunately, when a system setting hasn't been stored in the database,
it cannot be cached.
Meanwhile, this PR also uses context cache for push email avatar display
which should avoid to read user table via email address again and again.
According to my local test, this should reduce dashboard elapsed time
from 150ms -> 80ms .
Just like `models/unittest`, the testing helper functions should be in a
separate package: `contexttest`
And complete the TODO:
> // TODO: move this function to other packages, because it depends on

it's not easy to test them separately since they are all about the

Fix#24662.
Replace #24822 and #25708 (although it has been merged)
## Background
In the past, Gitea supported issue searching with a keyword and
conditions in a less efficient way. It worked by searching for issues
with the keyword and obtaining limited IDs (as it is heavy to get all)
on the indexer (bleve/elasticsearch/meilisearch), and then querying with
conditions on the database to find a subset of the found IDs. This is
why the results could be incomplete.
To solve this issue, we need to store all fields that could be used as
conditions in the indexer and support both keyword and additional
conditions when searching with the indexer.
## Major changes
- Redefine `IndexerData` to include all fields that could be used as
filter conditions.
- Refactor `Search(ctx context.Context, kw string, repoIDs []int64,
limit, start int, state string)` to `Search(ctx context.Context, options
*SearchOptions)`, so it supports more conditions now.
- Change the data type stored in `issueIndexerQueue`. Use
`IndexerMetadata` instead of `IndexerData` in case the data has been
updated while it is in the queue. This also reduces the storage size of
the queue.
- Enhance searching with Bleve/Elasticsearch/Meilisearch, make them
fully support `SearchOptions`. Also, update the data versions.
- Keep most logic of database indexer, but remove
`issues.SearchIssueIDsByKeyword` in `models` to avoid confusion where is
the entry point to search issues.
- Start a Meilisearch instance to test it in unit tests.
- Add unit tests with almost full coverage to test
Bleve/Elasticsearch/Meilisearch indexer.

The JSONRedirect/JSONOK/JSONError functions were put into "Base" context
incorrectly, it would cause abuse.
Actually, they are for "web context" only, so, move them to the correct

- Tell the renderer to use the `document` mode, so it's consistent with
other renderers.
- Use the same padding as `.file-view.markup`, so it's consistent with

Fix#25627
1. `ctx.Data["Link"]` should use relative URL but not AppURL
2. The `data-params` is incorrect because it doesn't contain "page". JS
can simply use "window.location.search" to construct the AJAX URL
3. The `data-xxx` and `id` in notification_subscriptions.tmpl were
copied&pasted, they don't have affect.
A couple of notes:
* Future changes should refactor arguments into a struct
* This filtering only is supported by meilisearch right now
* Issue index number is bumped which will cause a re-index
Fixes#24723
Direct serving of content aka HTTP redirect is not mentioned in any of
the package registry specs but lots of official registries do that so it
should be supported by the usual clients.
Related #25559
Current behaviour:
1. Deletion of a package version
2. Redirect to the owners package list
New behaviour:
1. Deletion of a package version
2.1. If there are more versions available, redirect to the package again
2.2. If there are no versions available, redirect to the owners package
list
Refactor `modules/indexer` to make it more maintainable. And it can be
easier to support more features. I'm trying to solve some of issue
searching, this is a precursor to making functional changes.
Current supported engines and the index versions:
| engines | issues | code |
| - | - | - |
| db | Just a wrapper for database queries, doesn't need version | - |
| bleve | The version of index is **2** | The version of index is **6**
|
| elasticsearch | The old index has no version, will be treated as
version **0** in this PR | The version of index is **1** |
| meilisearch | The old index has no version, will be treated as version
**0** in this PR | - |
## Changes
### Split
Splited it into mutiple packages
```text
indexer
├── internal
│ ├── bleve
│ ├── db
│ ├── elasticsearch
│ └── meilisearch
├── code
│ ├── bleve
│ ├── elasticsearch
│ └── internal
└── issues
├── bleve
├── db
├── elasticsearch
├── internal
└── meilisearch
```
- `indexer/interanal`: Internal shared package for indexer.
- `indexer/interanal/[engine]`: Internal shared package for each engine
(bleve/db/elasticsearch/meilisearch).
- `indexer/code`: Implementations for code indexer.
- `indexer/code/internal`: Internal shared package for code indexer.
- `indexer/code/[engine]`: Implementation via each engine for code
indexer.
- `indexer/issues`: Implementations for issues indexer.
### Deduplication
- Combine `Init/Ping/Close` for code indexer and issues indexer.
- ~Combine `issues.indexerHolder` and `code.wrappedIndexer` to
`internal.IndexHolder`.~ Remove it, use dummy indexer instead when the
indexer is not ready.
- Duplicate two copies of creating ES clients.
- Duplicate two copies of `indexerID()`.
### Enhancement
- [x] Support index version for elasticsearch issues indexer, the old
index without version will be treated as version 0.
- [x] Fix spell of `elastic_search/ElasticSearch`, it should be
`Elasticsearch`.
- [x] Improve versioning of ES index. We don't need `Aliases`:
- Gitea does't need aliases for "Zero Downtime" because it never delete
old indexes.
- The old code of issues indexer uses the orignal name to create issue
index, so it's tricky to convert it to an alias.
- [x] Support index version for meilisearch issues indexer, the old
index without version will be treated as version 0.
- [x] Do "ping" only when `Ping` has been called, don't ping
periodically and cache the status.
- [x] Support the context parameter whenever possible.
- [x] Fix outdated example config.
- [x] Give up the requeue logic of issues indexer: When indexing fails,
call Ping to check if it was caused by the engine being unavailable, and
only requeue the task if the engine is unavailable.
- It is fragile and tricky, could cause data losing (It did happen when
I was doing some tests for this PR). And it works for ES only.
- Just always requeue the failed task, if it caused by bad data, it's a
bug of Gitea which should be fixed.

1. The "web" package shouldn't depends on "modules/context" package,
instead, let each "web context" register themselves to the "web"
package.
2. The old Init/Free doesn't make sense, so simplify it
* The ctx in "Init(ctx)" is never used, and shouldn't be used that way
* The "Free" is never called and shouldn't be called because the SSPI
instance is shared

## Changes
- Adds the following high level access scopes, each with `read` and
`write` levels:
- `activitypub`
- `admin` (hidden if user is not a site admin)
- `misc`
- `notification`
- `organization`
- `package`
- `issue`
- `repository`
- `user`
- Adds new middleware function `tokenRequiresScopes()` in addition to
`reqToken()`
- `tokenRequiresScopes()` is used for each high-level api section
- _if_ a scoped token is present, checks that the required scope is
included based on the section and HTTP method
- `reqToken()` is used for individual routes
- checks that required authentication is present (but does not check
scope levels as this will already have been handled by
`tokenRequiresScopes()`
- Adds migration to convert old scoped access tokens to the new set of
scopes
- Updates the user interface for scope selection

## tokenRequiresScopes Design Decision
- `tokenRequiresScopes()` was added to more reliably cover api routes.
For an incoming request, this function uses the given scope category
(say `AccessTokenScopeCategoryOrganization`) and the HTTP method (say
`DELETE`) and verifies that any scoped tokens in use include
`delete:organization`.
- `reqToken()` is used to enforce auth for individual routes that
require it. If a scoped token is not present for a request,
`tokenRequiresScopes()` will not return an error
## TODO
- [x] Alphabetize scope categories
- [x] Change 'public repos only' to a radio button (private vs public).
Also expand this to organizations
- [X] Disable token creation if no scopes selected. Alternatively, show
warning
- [x] `reqToken()` is missing from many `POST/DELETE` routes in the api.
`tokenRequiresScopes()` only checks that a given token has the correct
scope, `reqToken()` must be used to check that a token (or some other
auth) is present.
- _This should be addressed in this PR_
- [x] The migration should be reviewed very carefully in order to
minimize access changes to existing user tokens.
- _This should be addressed in this PR_
- [x] Link to api to swagger documentation, clarify what
read/write/delete levels correspond to
- [x] Review cases where more than one scope is needed as this directly
deviates from the api definition.
- _This should be addressed in this PR_
- For example:
```go
m.Group("/users/{username}/orgs", func() {
m.Get("", reqToken(), org.ListUserOrgs)
m.Get("/{org}/permissions", reqToken(), org.GetUserOrgsPermissions)
}, tokenRequiresScopes(auth_model.AccessTokenScopeCategoryUser,
auth_model.AccessTokenScopeCategoryOrganization),
context_service.UserAssignmentAPI())
```
## Future improvements
- [ ] Add required scopes to swagger documentation
- [ ] Redesign `reqToken()` to be opt-out rather than opt-in
- [ ] Subdivide scopes like `repository`
- [ ] Once a token is created, if it has no scopes, we should display
text instead of an empty bullet point
- [ ] If the 'public repos only' option is selected, should read
categories be selected by default

Don't really know a better name for this. I've gone through some Forms
and added missing HTML attributes (mostly `maxlength`). I tried to fill
the Forms with dummy Data and see if Gitea throws a Error (e.g. maximum
length). If yes, I added the missing HTML attribute.
While working on this, I discovered that the Form to add OAuth2 Apps
just silently fails when filled with invalid data, so I fixed that too.
This PR is a refactor at the beginning. And now it did 4 things.
- [x] Move renaming organizaiton and user logics into services layer and
merged as one function
- [x] Support rename a user capitalization only. For example, rename the
user from `Lunny` to `lunny`. We just need to change one table `user`
and others should not be touched.
- [x] Before this PR, some renaming were missed like `agit`
- [x] Fix bug the API reutrned from `http.StatusNoContent` to `http.StatusOK`
This PR
- [x] Move some functions from `issues.go` to `issue_stats.go` and
`issue_label.go`
- [x] Remove duplicated issue options `UserIssueStatsOption` to keep
only one `IssuesOptions`
Implements displaying a README.md file present in a users ```.profile```
repository on the users profile page. If no such repository/file is
present, the user's profile page remains unchanged.

This PR splits it to separate files, eg: context_request.go,

This PR will help:
1. The future refactoring for Gitea's web context (eg: simplify the context)
2. Introduce proper "range request" support
3. Introduce context function

There was only one `IsRepositoryExist` function, it did: `has && isDir`
However it's not right, and it would cause 500 error when creating a new
repository if the dir exists.
Then, it was changed to `has || isDir`, it is still incorrect, it
affects the "adopt repo" logic.
To make the logic clear:
* IsRepositoryModelOrDirExist
* IsRepositoryModelExist
Always respect the `setting.UI.ShowUserEmail` and `KeepEmailPrivate`
setting.
* It doesn't make sense to show user's own E-mail to themself.
* Always hide the E-mail if KeepEmailPrivate=true, then the user could
know how their profile page looks like for others.
* Revert the `setting.UI.ShowUserEmail` change from #4981 . This setting
is used to control the E-mail display, not only for the user list page.
ps: the incorrect `<div .../>` tag on the profile page has been fixed by
#23748 together, so this PR becomes simpler.
The `q` parameter was not rendered in pagination links because
`context.Pagination:AddParam` checks for existance of the parameter in
`ctx.Data` where it was absent. Added the parameter there to fix it.
