# Why this PR comes
At first, I'd like to help users like #23636 (there are a lot)
The unclear "Internal Server Error" is quite anonying, scare users,
frustrate contributors, nobody knows what happens.
So, it's always good to provide meaningful messages to end users (of
course, do not leak sensitive information).
When I started working on the "response message to end users", I found
that the related code has a lot of technical debt. A lot of copy&paste
code, unclear fields and usages.
So I think it's good to make everything clear.
# Tech Backgrounds
Gitea has many sub-commands, some are used by admins, some are used by
SSH servers or Git Hooks. Many sub-commands use "internal API" to
communicate with Gitea web server.
Before, Gitea server always use `StatusCode + Json "err" field` to
return messages.
* The CLI sub-commands: they expect to show all error related messages
to site admin
* The Serv/Hook sub-commands (for git clients): they could only show
safe messages to end users, the error log could only be recorded by
"SSHLog" to Gitea web server.
In the old design, it assumes that:
* If the StatusCode is 500 (in some functions), then the "err" field is
error log, shouldn't be exposed to git client.
* If the StatusCode is 40x, then the "err" field could be exposed. And
some functions always read the "err" no matter what the StatusCode is.
The old code is not strict, and it's difficult to distinguish the
messages clearly and then output them correctly.
# This PR
To help to remove duplicate code and make everything clear, this PR
introduces `ResponseExtra` and `requestJSONResp`.
* `ResponseExtra` is a struct which contains "extra" information of a
internal API response, including StatusCode, UserMsg, Error
* `requestJSONResp` is a generic function which can be used for all
cases to help to simplify the calls.
* Remove all `map["err"]`, always use `private.Response{Err}` to
construct error messages.
* User messages and error messages are separated clearly, the `fail` and
`handleCliResponseExtra` will output correct messages.
* Replace all `Internal Server Error` messages with meaningful (still
safe) messages.
This PR saves more than 300 lines, while makes the git client messages
more clear.
Many gitea-serv/git-hook related essential functions are covered by
tests.

Gitea emoji dataset was out of date because it gets manually built and
hasn't been rebuilt since it was added. This means Gitea doesn't
recognize some newer emoji or changes to existing ones.
After changing the max unicode version to 14 I just ran: `go run
build/generate-emoji.go`
This should address the initial issue seen in #22153 where Gitea doesn't
recognize a standard alias used elsewhere when importing content.
14 is the latest supported version from the upstream source as 15 is not
widely supported (in their opinion) yet
Change all license headers to comply with REUSE specification.
Fix#16132

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

* Update emoji dataset with skin tone variants
Since the format of emoji that support skin tone modifiers is predictable we can add different variants into our dataset when generating it so that we can match and properly style most skin tone variants of emoji. No real code change here other than what generates the dataset and the data itself.
* use escape unicode sequence in map

* Support unicode emojis and remove emojify.js
This PR replaces all use of emojify.js and adds unicode emoji support to various areas of gitea.
This works in a few ways:
First it adds emoji parsing support into gitea itself. This allows us to
* Render emojis from valid alias (😄)
* Detect unicode emojis and let us put them in their own class with proper aria-labels and styling
* Easily allow for custom "emoji"
* Support all emoji rendering and features without javascript
* Uses plain unicode and lets the system render in appropriate emoji font
* Doesn't leave us relying on external sources for updates/fixes/features
That same list of emoji is also used to create a json file which replaces the part of emojify.js that populates the emoji search tribute. This file is about 35KB with GZIP turned on and I've set it to load after the page renders to not hinder page load time (and this removes loading emojify.js also)
For custom "emoji" it uses a pretty simple scheme of just looking for /emojis/img/name.png where name is something a user has put in the "allowed reactions" setting we already have. The gitea reaction that was previously hard coded into a forked copy of emojify.js is included and works as a custom reaction under this method.
The emoji data sourced here is from https://github.com/github/gemoji which is the gem library Github uses for their emoji rendering (and a data source for other sites). So we should be able to easily render any emoji and :alias: that Github can, removing any errors from migrated content. They also update it as well, so we can sync when there are new unicode emoji lists released.
I've included a slimmed down and slightly modified forked copy of https://github.com/knq/emoji to make up our own emoji module. The code is pretty straight forward and again allows us to have a lot of flexibility in what happens.
I had seen a few comments about performance in some of the other threads if we render this ourselves, but there doesn't seem to be any issue here. In a test it can parse, convert, and render 1,000 emojis inside of a large markdown table in about 100ms on my laptop (which is many more emojis than will ever be in any normal issue). This also prevents any flickering and other weirdness from using javascript to render some things while using go for others.
Not included here are image fall back URLS. I don't really think they are necessary for anything new being written in 2020. However, managing the emoji ourselves would allow us to add these as a feature later on if it seems necessary.
