RenderEmojiPlain(emoji.ReplaceAliases) should be called explicitly for
some contents, but not for everything.
Actually in modern days, in most cases it doesn't need such
"ReplaceAliases". So only keep it for issue/PR titles.
If anyone really needs to do ReplaceAliases for some contents, I will
propose a following fix.

GitLab generates "system notes" whenever an event happens within the
platform. Unlike Gitea, those events are stored and retrieved as text
comments with no semantic details. The only way to tell whether a
comment was generated in this manner is the `system` flag on the note
type.
This PR adds detection for a new specific kind of event: Changing the
target branch of a PR. When detected, it is downloaded using Gitea's
type for this event, and eventually uploaded into Gitea in the expected
format, i.e. with no text content in the comment.
This PR also updates the template used to render comments to add support
for migrated comments of this type.

Adds a label to Pull Requests that were created using AGit-Flow,
in order to prevent situations where a contributor uses AGit-Flow
to push new changes - only to realize that they did not use AGit-Flow
in the first place, and that they just opened a new PR accidentally
(that was me).
Also intended to raise general awareness about the feature. Some
additional work, such as adding a tooltip, still needs to be
done.
A small typo fix for a comment and (exclusively) formatting fixes
in the copyright header are also included.

It's possible for reviews to not be assiocated with users, when they
were migrated from another forge instance. In the migration code,
there's no sanitization check for author names, so they could contain
HTML tags and thus needs to be properely escaped.
Follow #29165. These HTML strings are safe to be rendered directly, to
avoid double-escaping.

The issue filter links should not be crawled by search engines, because
they they only filter results, and contain nothing new, yet, they put a
considerable load on the server.
To stop - well behaving - search engines from following these links, add
a `rel="nofollow"` property to them. The same property is already
present on the archive download links, and plenty of other places.
Fixes#2361.

Follow-up of #2282 and #2296 (which tried to address #2278)
One of the issue with the previous PR is that when a conversation on the Files tab was marked as "resolved", it would fetch all the comments for that line (even the outdated ones, which should not be shown on this page - except when explicitly activated).
To properly fix this, I have changed `FetchCodeCommentsByLine` to `FetchCodeConversation`. Its role is to fetch all comments related to a given (review, path, line) and reverted my changes in the template (which were based on a misunderstanding).

With this option, it is possible to require a linear commit history with
the following benefits over the next best option `Rebase+fast-forward`:
The original commits continue existing, with the original signatures
continuing to stay valid instead of being rewritten, there is no merge
commit, and reverting commits becomes easier.

- Use maintained fork https://github.com/golangci/misspell
- Rename `mispell-check` to `lint-spell`, add `lint-spell-fix`
- Run `lint-spell` in separate actions step
- Lint more files, fix discovered issues
- Remove inaccurate and outdated info in docs (we do not need GOPATH for
tools anymore)
Maybe later we can add more spellchecking tools, but I have not found
any good ones yet.

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

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>

When JavaScript is not loaded, fall back to displaying reaction tooltips
with the default browser `title` attribute. An element with a present
but empty `data-tooltip-content` will use the `title` attribute for its
tippy.js tooltip content, so when JavaScript is enabled, this functions
the same as the current behavior.
When an assignee changed event comment is rendered, most of it is
guarded behind the assignee ID not being 0. However, if it is 0, that
results in quite broken rendering for that comment and the next one.
This can happen, for example, when repository data imported from outside
of Gitea is incomplete.
This PR makes sure comments with an assignee ID of 0 are not rendered at
all.

* Show checkout instructions also when there is no permission to push,
for anyone who wants to locally test the changes.
* First checkout the branch exactly as is, without immediately having to
solve merge conflicts. Leave this to the merge step, since it's often
convenient to test a change without worrying about this.
* Use `git fetch -u`, so an existing local branch is updated when
re-testing the same pull request. But not the more risky `git fetch -f`
in to handle force pushes, as we don't want to accidentally overwrite
important local changes.
* Show different merge command depending on the chosen merge style,
interactively updated.
If you set a checkbox as required in a issue form at the moment, the
checkbox is checked and read only, what does not make much sense. With
this PR, the Checkbox actually needs to be checked. The label supports
now also Markdown. This matches GitHub's behaviour.
And yes, I know the CSS is a ugly workaround. It looks like the given
CSS code is part Fomantic and I don't know how to change that. The
Maintainers are free to change that.
- The review type '22' is a general comment type that is attached to
single codecomments, reviews with multiple comments or to simple approve
and request changes comment. This comment can be used to create a link
towards this action on an pull request.
- Adds an anchor to the review comment type, so that when its getting
linked to it, it actually jumps towards that event.
- This also now fixes the behavior that after you created a review you
will be redirected to that review and because this is an general comment
type other mails will also be 'fixed' such as the approved or request
changes.

Part of #27065
This PR touches functions used in templates. As templates are not static
typed, errors are harder to find, but I hope I catch it all. I think
some tests from other persons do not hurt.
1. Use `gt-invisible` instead of `invisible`.
2. Use `gt-word-break` instead of `dont-break-out` (there is a slight
different "hyphens", but I think it won't affect too much since it is
only used for the "full name").
3. Remove `.small.button:has(svg)` , now our buttons could layout SVG
correctly, and actually I didn't see this CSS class is used in code.
Each change is tested manually line by line. There are too many changes
so I can't share dozens of screenshots.
In short:
1. `ui right` could be still used in `ui top attached header`, because
there is a special case.
2. A lot of `ui right` are just no-op, so they can be removed safely.
3. Some of the `ui right` should be replaced by `gt-float-right` (to
avoid breaking, leave them to the future).
4. A few of the `ui right` could be rewritten by flex.
Fix#26731
Almost all "tabindex" in code are incorrect.
1. All "input/button" by default are focusable, so no need to use "tabindex=0"
2. All "div/span" by default are not focusable, so no need to use "tabindex=-1"
3. All "dropdown" are focusable by framework, so no need to use "tabindex"
4. Some tabindex values are incorrect (eg: `new_form.tmpl`), so remove them

## Archived labels
This adds the structure to allow for archived labels.
Archived labels are, just like closed milestones or projects, a medium to hide information without deleting it.
It is especially useful if there are outdated labels that should no longer be used without deleting the label entirely.
## Changes
1. UI and API have been equipped with the support to mark a label as archived
2. The time when a label has been archived will be stored in the DB
## Outsourced for the future
There's no special handling for archived labels at the moment.
This will be done in the future.

Numerous small UI fixes:
- Fix double border in collaborator list
- Fix system notice table background
- Mute links in repo and org lists
- Downsize projects edit buttons
- Improve milestones and project list rendering
- Condense milestone list entry to a single line of "metas"
- Mute ".." button in repo files list
So I found this [linter](https://github.com/Riverside-Healthcare/djlint)
which features a mode for go templates, so I gave it a try and it did
find a number of valid issue, like unbalanced tags etc. It also has a
number of bugs, I had to disable/workaround many issues.
Given that this linter is written in python, this does add a dependency
on `python` >= 3.8 and `poetry` to the development environment to be
able to run this linter locally.
- `e.g.` prefixes on placeholders are removed because the linter had a
false-positive on `placeholder="e.g. cn=Search"` for the `attr=value`
syntax and it's not ideal anyways to write `e.g.` into a placeholder
because a placeholder is meant to hold a sample value.
- In `templates/repo/settings/options.tmpl` I simplified the logic to
not conditionally create opening tags without closing tags because this
stuff confuses the linter (and possibly the reader as well).

Fixes https://github.com/go-gitea/gitea/issues/25130
The old code uses `$(this).next()` to get `dismiss-review-modal`.
At first, it will get `$(#dismiss-review-modal)`, but the next time it
will get `$(#dismiss-review-modal).next();`
and then `$(#dismiss-review-modal).next().next();`.
Because div `dismiss-review-modal` will be removed when
`dismiss-review-btn` clicked.
Maybe the right usage is adding `show-modal` class and `data-modal`
attribute.

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 adds the ability to pin important Issues and Pull Requests. You can
also move pinned Issues around to change their Position. Resolves#2175.
## Screenshots
The Design was mostly copied from the Projects Board.
## Implementation
This uses a new `pin_order` Column in the `issue` table. If the value is
set to 0, the Issue is not pinned. If it's set to a bigger value, the
value is the Position. 1 means it's the first pinned Issue, 2 means it's
the second one etc. This is dived into Issues and Pull requests for each
Repo.
## TODO
- [x] You can currently pin as many Issues as you want. Maybe we should
add a Limit, which is configurable. GitHub uses 3, but I prefer 6, as
this is better for bigger Projects, but I'm open for suggestions.
- [x] Pin and Unpin events need to be added to the Issue history.
- [x] Tests
- [x] Migration

weird edge cases are very welcome!**

There was some recent discussion about this in Discord `ui-design`
channel and the conclusion was that
https://github.com/go-gitea/gitea/issues/24305 should have fixed their
OS font installation to have semibold weights.
I have now tested this 601 weight on a Windows 10 machine on Firefox
myself, and I immediately noticed that bold was excessivly bold and
rendering as 700 because browsers are biased towards bolder fonts. So
revert this back to the previous value.
Visually, nothing should have changed.
Changes include
- Convert most `<a [no href]>` to `<button>` when (re-)viewing files:
- `<a [no href]>` are, by HTML definition, not a link and hence cannot
be focused
- `<a class="ui button">` can now be clicked (again?) using
<kbd>Enter</kbd>
- Previously, the installed keypress handler on `.ui.button` elements
disabled it for links somehow
- The `(un)escape file`, the `expand section` and the `expand/collapse
file` buttons can now be focused (and subsequently clicked using only
the keyboard)
- You can now press <kbd>Space</kbd> on a focused `View file` checkbox
to mark the file as viewed.
- previously, this was impossible as this checkbox listened on the wrong
event listener
The `add code comment` button has been left inaccessible for now as it
requires quite a bit of extra logic so that it is unhidden when it is
focused (you can otherwise focus it without seeing it as you are not
hovering on the corresponding line).

Clean up a few cases where avatar dimensions were overwritten via CSS,
which were no longer needed or were possible to set via HTML width.
Also included are two small fixes:
- Fix one more case of incorrect avatar offset on review timeline
- Vertically center avatars in review sidebar
There is more to be done here, but some of the work depends on Fomantic

Partial regression of #24393, not only regression, but broken for long
time, 24393 didn't really improve it but used wrong `overflow: scroll`.
Actually, that "ui secondary filter menu labels" shouldn't be set as
scrollable (I missed that at that time), the problem is: if a "ui menu"
has "dropdown" items, then it should not be scrollable. Otherwise the
dropdown menu can't be shown correctly.
And there are more problems:
* The "issue-filters" shouldn't be used anywhere else (copying&pasting
problem again ....)
* There is also an "issue-actions" container, it should also be fixed.
* There are similar problems on the milestone page.
* The old comment in code: "grid column" doesn't work well.
The major changes of this PR are: use "flex: 1" instead of "ui grid
column".
After this PR, not 100% perfect but much better than before.
Close#24302

This PR focused on CSS style fine-tune, main changes:
1. Give `.ui.ui.ui.container` a width of `1280px` with a max-width of
`calc(100vw - 64px)`, so the main contents looks better on large
devices.
2. Share styles for table elements in all levels settings pages to fix
overflow of runners table on mobile and for consistency (The headers on
mobile can be further improved, but haven't found a proper way yet).
3. Use [stackable
grid](https://fomantic-ui.com/collections/grid.html#stackable) and
[device column width](https://fomantic-ui.com/examples/responsive.html)
for responsiveness for some pages (repo/org collaborators settings

"Datetime" ([^"]+) "Fallback" ([^\)]+\)?) ?\)?\}\}` -> `{{DateTime "$1
$2 $3}}`)

The improvements:
1. The `contains` functions are covered by tests
2. The inconsistent behavior of `containGeneric` is replaced by
`StringUtils.Contains` and `SliceUtils.Contains`
3. In the future we can move more help functions into XxxUtils to
simplify the `helper.go` and reduce unnecessary global functions.
FAQ:
1. Why it's called `StringUtils.Contains` but not `strings.Contains`
like Golang?
Because our `StringUtils` is not Golang's `strings` package. There will
be our own string functions.
