Remove unmaintainable sanitizer rules. No need to add special "class"
regexp rules anymore, use RenderInternal.SafeAttr instead, more details
(and examples) are in the tests
There were too many patches to the Render system, it's really difficult
to make further improvements.
This PR clears the legacy problems and fix TODOs.
1. Rename `RenderContext.Type` to `RenderContext.MarkupType` to clarify
its usage.
2. Use `ContentMode` to replace `meta["mode"]` and `IsWiki`, to clarify
the rendering behaviors.
3. Use "wiki" mode instead of "mode=gfm + wiki=true"
4. Merge `renderByType` and `renderByFile`
5. Add more comments
----
The problem of "mode=document": in many cases it is not set, so many
non-comment places use comment's hard line break incorrectly
To make the markup package easier to maintain:
1. Split some go files into small files
2. Use a shared util.NopCloser, remove duplicate code
3. Remove unused functions
Fix#31271.
When gogit is enabled, `IsObjectExist` calls
`repo.gogitRepo.ResolveRevision`, which is not correct. It's for
checking references not objects, it could work with commit hash since
it's both a valid reference and a commit object, but it doesn't work
with blob objects.
So it causes #31271 because it reports that all blob objects do not
exist.
This change fixes cases when a Wiki page refers to a video stored in the
Wiki repository using relative path. It follows the similar case which
has been already implemented for images.
Test plan:
- Create repository and Wiki page
- Clone the Wiki repository
- Add video to it, say `video.mp4`
- Modify the markdown file to refer to the video using `<video
src="video.mp4">`
- Commit the Wiki page
- Observe that the video is properly displayed

In Wiki pages, short-links created to local Wiki files were always
expanded as regular Wiki Links. In particular, if a link wanted to point
to a file that Gitea doesn't know how to render (e.g, a .zip file), a
user following the link would be silently redirected to the Wiki's home
page.
This change makes short-links* in Wiki pages be expanded to raw wiki
links, so these local wiki files may be accessed without manually
accessing their URL.
* only short-links ending in a file extension that isn't renderable are
affected.
Closes#27121.

Follow #29024
Major changes:
* refactor validLinksPattern to fullURLPattern and add comments, now it
accepts "protocol:" prefix
* rename `IsLink*` to `IsFullURL*`, and remove unnecessray "mailto:"
check
* fix some comments (by the way)
* rename EmojiShortCodeRegex -> emojiShortCodeRegex (by the way)
Clarify when "string" should be used (and be escaped), and when
"template.HTML" should be used (no need to escape)
And help PRs like #29059 , to render the error messages correctly.
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:
<details>
<summary>Profile</summary>
https://try.gitea.io/KN4CK3R
</details>

In #26365 issue references were disabled entirely for documents,
intending to match GitHub behavior. However cross-references do appear
to work in documents on GitHub.
This is useful for example to write release notes in a markdown document
and reference issues. While the simpler syntax may create links when not
intended, hopefully the cross-reference syntax is unique enough to avoid
it.
Fix#28526, regression of
* #26365
(although the author of #26365 has recent activities, but there is no
response for the regression, so I proposed this quick fix and keep the
fix simple to make it easier to backport to 1.21)
- Currently the post processing will transform all issue indexes (such as `#6`) into a clickable link.
- This makes sense in an situation like issues or PRs,
where referencing to other issues is quite common
and only referencing their issue index is an handy and efficient way to do it.
- Currently this is also run for documents
(which is the user profile and viewing rendered files),
but in those situations it's less common to reference issues by their index and instead could mean something else.
- This patch disables this post processing for issue index for documents. Matches Github's behavior.
- Added unit tests.
- Resolves https://codeberg.org/Codeberg/Community/issues/1120

This branch continues the work of #23092 and attempts to rid the
codebase of any `nil` contexts when using a `RenderContext`.
Anything that renders markdown or does post processing may call
`markup.sha1CurrentPatternProcessor()`, and this runs
`git.OpenRepository()`, which needs a context. It will panic if the
context is `nil`. This branch attempts to _always_ include a context
when creating a `RenderContext` to prevent future crashes.

- Resolves#20109
The main purpose is to refactor the legacy `unknwon/com` package.
1. Remove most imports of `unknwon/com`, only `util/legacy.go` imports the legacy `unknwon/com`
2. Use golangci's depguard to process denied packages
3. Fix some incorrect values in golangci.yml, eg, the version should be quoted string `"1.18"`
4. Use correctly escaped content for `go-import` and `go-source` meta tags
5. Refactor `com.Expand` to our stable (and the same fast) `vars.Expand`, our `vars.Expand` can still return partially rendered content even if the template is not good (eg: key mistach).
* Add tests for references with dashes
This commit adds tests for full URLs referencing repos names and user
names containing a dash.
* Extend regex to match URLs to repos/users with dashes
* Don't panic & allow shorter sha1
- Don't panic when the full regex isn't matched and allow the usage of a
shorter sha1 being used.
- Resolves#18471
* Update modules/markup/html.go
