## Overview
Hi all, I'm a first-time contributor to Forgejo. I was looking for something interesting to contribute and the first thing that caught my attention was https://codeberg.org/forgejo/forgejo/issues/6043, a request for an enhancement to include "issue previews" when publishing links to social media platforms. As a bit of background, the way these platforms work is that they search for meta tags in the posted link's content, and if they find a meta `og:image` (along with other meta tags) they'll pull the image to include in the social media post. Forgejo currently provides an `og:image` tag but it just renders the repository or repository-owner's avatar.
This PR will render `og:image` for an issue or PR into a link to `{...}/summary-card`, which is a dynamically generated image that contains a summary of the issue.
## Design Notes
### Rendering / Rasterization
The tricky part of solving this problem is rendering an image that combines some text, some images, and some layout elements. To address this, I've created a `card` module which allows for a handful of operations:
- Create a new rendered image (a "Card")
- Add a margin to a card
- Split the card, horizontally or vertically, into two pieces with a proportional layout (eg. 70%/30%, as desired), each of which are "Cards" that render into the same root image
- Render text into a card, with line-wrapping and text-alignment capabilities
- Render an image onto a card
- Fetches an external image as safely as possible (for server-side fetch of Gravatar, etc.)
The card module can be reused to create `og:image` summary cards for any object in the future, although obviously it's capabilities are limited. The current implementation is on issues/PRs.
I considered a few alternative approaches before taking this approach, and here's why I rejected those options:
- Provide the summary card as an SVG object which could be rendered much more easily with a template file -- however, support for SVG isn't defined as positive for OpenGraph, and a quick look through some existing implementations suggest that it is not widely supported, if at all
- Rendering as HTML/CSS, or SVG, and then using an external tool to convert into a PNG (or other static) image -- this would be much nicer and easier to implement, but would require tying in some very heavy-weight dependencies
- Rendering using a more sophisticated graphics library, eg. cairo -- also would be nicer and easier to implement, but again a heavy dependency for a small functionality
As a result of the limited capabilities of the new card module, summary cards don't have icons on them (which would require SVG rasterization) or pretty status badges with colors and rounded rects. In the future if better drawing capabilities were added, the graphics could be improved, but it doesn't seem too important.
### External Avatars
In order to rasterize a user's avatar onto the summary card, it might have to be retrieved by the server from the external source (eg. Gravatar). A `fetchExternalImage` routine attempts to do this in the safest way possible to protect the server from any possible security exposure from this; (a) verifying that the content-types are acceptable, (b) ensuring that the file-size and image-size are within the safe bounds that are used for custom avatars, (c) using a very-short timeout to avoid stalling the server if an external dependency is offline.
### Caching
Summary cards are cached after rendered. This has the downside of causing updates to statuses, avatars, titles, etc. being stale on the summary card for the cache TTL. However, during testing I found that some social media engines like Mastodon will cause the summary card to be accessed a significant number of times after being referenced by a post, causing a mini-tornado of requests. The cache compensates for this to avoid server load in this situation.
### Scope
I'm considering out-of-scope:
- Summary cards on other objects (eg. repos, users) can be left for future implementation

The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org).
### Tests
- I added test coverage for Go changes...
- [x] in their respective `*_test.go` for unit tests.
- [x] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- ~~I added test coverage for JavaScript changes...~~ n/a, no JS changes
- [x] ~~in `web_src/js/*.test.js` if it can be unit tested.~~
- [x] ~~in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)).~~
- Manual testing
- [x] Access & attach screenshots of both an issue and a pull-request's summary card; see below
- [x] Ensure reasonable (non-crash) behavior of rendering text with glyphs outside the font -- correctly rendered as replacement unicode chars
- [x] Using a public test instance, verify that og:image behavior looks good on platforms like Mastodon and BlueSky
- [x] Bluesky: ✅
- [x] Mastodon: ✅ (Note that the summary card will be requested many times as the post is federated; either each server, or each client, will fetch it itself)
- [x] OpenGraph test site (https://www.opengraph.xyz/): ✅
- [x] Discord: Looks OK ✅; needs "twitter:card" to be set to "summary_large_image" to display the large-scale image, but (a) that's probably annoying to use, (b) probably wrong because it doesn't match Twitter Card's spec for a "photographic image", and (c) don't want to encourage/continue use of vendor-specific tag
- [x] Verify cases with user avatar missing (or autogen), and repo avatar missing (falls back to repo owner avatar)

### Documentation
- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
- OpenGraph capabilities are expected to work in the background without user awareness, and so there is no need for documentation to explain the capabilities for users.
### Release notes
- [ ] I do not want this change to show in the release notes.
- [x] I want the title to show in the release notes with a link to this pull request.
- [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.

* added a message for the case where the user's profile is private but the Public activity is not hidden
The activity is still hidden anyway because the profile is private, but previously the message would say:
`Your activity is visible to everyone, except for interactions in private spaces...`
which I would consider as a flaw of the original implementation. Now it will say:
`Your activity is only visible to you and the instance administrators because your profile is private...`
* started showing the message for admins that the activity they see should remain private in the case
where the whole profile is private, not just the activity tab. Previously it would say:
This activity is visible to everyone, but as an administrator you can also see interactions in private spaces.`
which I would also consider as a flaw of the original implementation. Now it will say:
`This activity is visible to you because you're an administrator, but the user wants it to remain private.`
* added test cases
* bumped up the number of our GPL-licensed files

For both screenshots, Forgejo would previously display misinformation.

If you want to get to the all state, you need to click Open while in open state or Closed while in closed state, which is very unintuitive. This PR adss a third button to get to this state.

- Follow up of #4819
- When no `ssh` executable is present, disable the UI and backend bits
that allow the creation of push mirrors that use SSH authentication. As
this feature requires the usage of the `ssh` binary.
- Integration test added.
- adds a header to indicate creating a new rule
- test that header is different between new and edit form
- consistently avoids colons in the form
- excludes some accessibility checks that require a global solution for
forms
- Continuation of https://github.com/go-gitea/gitea/pull/18835 (by
@Gusted, so it's fine to change copyright holder to Forgejo).
- Add the option to use SSH for push mirrors, this would allow for the
deploy keys feature to be used and not require tokens to be used which
cannot be limited to a specific repository. The private key is stored
encrypted (via the `keying` module) on the database and NEVER given to
the user, to avoid accidental exposure and misuse.
- CAVEAT: This does require the `ssh` binary to be present, which may
not be available in containerized environments, this could be solved by
adding a SSH client into forgejo itself and use the forgejo binary as
SSH command, but should be done in another PR.
- CAVEAT: Mirroring of LFS content is not supported, this would require
the previous stated problem to be solved due to LFS authentication (an
attempt was made at forgejo/forgejo#2544).
- Integration test added.
- Resolves#4416
UX/Translation changes:
- new teams: remove redundant tooltips that don't add meaningful information
- move general information to table fieldset
- new teams: rename "general" to "custom" access for clarity
- new teams: show labels beside options on mobile
Accessibility:
- semantic form elements allow easier navigation (fieldset, mostly)
- improve better labelling of new teams table
- fix accessibility scan issues
- TODO: the parts that "disable" form elements were not yet touched and
are not really accessible to screenreaders
Technical:
- replace two JavaScript solutions with one CSS standard
- implement a simpler grid (.simple-grid)
- simplify markup
- remove some webhook settings specific CSS
Testing:
- check more form content for accessibility issues
- but exclude tooltips from the scan :(
- reuse existing form tests from previous PR
