Multiple tests that worked fine on v1.20.4-1 started to fail after the
rebase onto v1.20.5-1. These tests are:
- TestGitAnnexPermissions/Private/Owner/HTTP/Init
- TestGitAnnexPermissions/Private/Owner/HTTP/Download
- TestGitAnnexPermissions/Private/Writer/HTTP/Init
- TestGitAnnexPermissions/Private/Writer/HTTP/Download
- TestGitAnnexPermissions/Private/Reader/HTTP/Init
- TestGitAnnexPermissions/Private/Reader/HTTP/Download
What these tests have in common is that they all operate on a private
repository via http with authentication.
They broke at some point between v1.20.4-1 and v1.20.5-1, so I did a
bisect between these two points running the offending tests. This
brought me to the conclusion that
ee48c0d5ea introduced the issue.
The thing is, this commit does not change any code, it only changes the
test environment. Among other things that didn't look as suspicious, it
changes the container image from a bespoke test_env image based on
debian bullseye to a node image based on debian bookworm. Obviously,
this means that there are many version differences between the two.
The first one I looked at was git. The previous bullseye image used a
manually installed git version 2.40.0, while the bookworm image has
2.39.2 installed. Updating git in the new image did not fix the issue,
however.
The next thing I looked at was the git-annex version. Bullseye had
8.20210223 installed and worked, while bookworm used 10.20230126 when
the tests broke. So I tried my luck upgrading to a more recent version
via neurodebian (10.20240227-1~ndall+1). This still worked fine on
bullseye and now also works fine on bookworm.
I have no idea why this specific version of git-annex broke the tests,
but at least there was a commit to pinpoint this to, which isn't always
the case with docker images silently changing beneath you...
Below are the versions as they are reported by git and git-annex:

This updates the repo index/file view endpoints so annex files match the way
LFS files are rendered, making annexed files accessible via the web instead of
being black boxes only accessible by git clone.
This mostly just duplicates the existing LFS logic. It doesn't try to combine itself
with the existing logic, to make merging with upstream easier. If upstream ever
decides to accept, I would like to try to merge the redundant logic.
The one bit that doesn't directly copy LFS is my choice to hide annex-symlinks.
LFS files are always _pointer files_ and therefore always render with the "file"
icon and no special label, but annex files come in two flavours: symlinks or
pointer files. I've conflated both kinds to try to give a consistent experience.
The tests in here ensure the correct download link (/media, from the last PR)
renders in both the toolbar and, if a binary file (like most annexed files will be),
in the main pane, but it also adds quite a bit of code to make sure text files
that happen to be annexed are dug out and rendered inline like LFS files are.
Previously, Gitea's LFS support allowed direct-downloads of LFS content,
via http://$HOSTNAME:$PORT/$USER/$REPO/media/branch/$BRANCH/$FILE
Expand that grace to git-annex too. Now /media should provide the
relevant *content* from the .git/annex/objects/ folder.
This adds tests too. And expands the tests to try symlink-based annexing,
since /media implicitly supports both that and pointer-file-based annexing.
This moves the `annexObjectPath()` helper out of the tests and into a
dedicated sub-package as `annex.ContentLocation()`, and expands it with
`.Pointer()` (which validates using `git annex examinekey`),
`.IsAnnexed()` and `.Content()` to make it a more useful module.
The tests retain their own wrapper version of `ContentLocation()`
because I tried to follow close to the API modules/lfs uses, which in
terms of abstract `git.Blob` and `git.TreeEntry` objects, not in terms
of `repoPath string`s which are more convenient for the tests.
This makes HTTP symmetric with SSH clone URLs.
This gives us the fancy feature of _anonymous_ downloads,
so people can access datasets without having to set up an
account or manage ssh keys.
Previously, to access "open access" data shared this way,
users would need to:
1. Create an account on gitea.example.com
2. Create ssh keys
3. Upload ssh keys (and make sure to find and upload the correct file)
4. `git clone git@gitea.example.com:user/dataset.git`
5. `cd dataset`
6. `git annex get`
This cuts that down to just the last three steps:
1. `git clone https://gitea.example.com/user/dataset.git`
2. `cd dataset`
3. `git annex get`
This is significantly simpler for downstream users, especially for those
unfamiliar with the command line.
Unfortunately there's no uploading. While git-annex supports uploading
over HTTP to S3 and some other special remotes, it seems to fail on a
_plain_ HTTP remote. See https://github.com/neuropoly/gitea/issues/7
and https://git-annex.branchable.com/forum/HTTP_uploads/#comment-ce28adc128fdefe4c4c49628174d9b92.
This is not a major loss since no one wants uploading to be anonymous anyway.
To support private repos, I had to hunt down and patch a secret extra security
corner that Gitea only applies to HTTP for some reason (services/auth/basic.go).
This was guided by https://git-annex.branchable.com/tips/setup_a_public_repository_on_a_web_site/

[git-annex](https://git-annex.branchable.com/) is a more complicated cousin to
git-lfs, storing large files in an optional-download side content. Unlike lfs,
it allows mixing and matching storage remotes, so the content remote(s) doesn't
need to be on the same server as the git remote, making it feasible to scatter
a collection across cloud storage, old harddrives, or anywhere else storage can
be scavenged. Since this can get complicated, fast, it has a content-tracking
database (`git annex whereis`) to help find everything later.
The use-case we imagine for including it in Gitea is just the simple case, where
we're primarily emulating git-lfs: each repo has its large content at the same URL.
Our motivation is so we can self-host https://www.datalad.org/ datasets, which
currently are only hostable by fragilely scrounging together cloud storage --
and having to manage all the credentials associated with all the pieces -- or at
https://openneuro.org which is fragile in its own ways.
Supporting git-annex also allows multiple Gitea instance to be annex remotes for
each other, mirroring the content or otherwise collaborating the split up the
hosting costs.
Enabling

TODO
HTTP
----
TODO
Permission Checking
-------------------
This tweaks the API in routers/private/serv.go to expose the calling user's
computed permission, instead of just returning HTTP 403.
This doesn't fit in super well. It's the opposite from how the git-lfs support is
done, where there's a complete list of possible subcommands and their matching
permission levels, and then the API compares the requested with the actual level
and returns HTTP 403 if the check fails.
But it's necessary. The main git-annex verbs, 'git-annex-shell configlist' and
'git-annex-shell p2pstdio' are both either read-only or read-write operations,
depending on the state on disk on either end of the connection and what the user
asked it to ask for, with no way to know before git-annex examines the situation.
So tell the level via GIT_ANNEX_READONLY and trust it to handle itself.
In the older Gogs version, the permission was directly read in cmd/serv.go:
```
mode, err = db.UserAccessMode(user.ID, repo)
```
- 966e925cf3/internal/cmd/serv.go (L334)
but in Gitea permission enforcement has been centralized in the API layer.
(perhaps so the cmd layer can avoid making direct DB connections?)
Deletion
--------
git-annex has this "lockdown" feature where it tries
really quite very hard to prevent you deleting its
data, to the point that even an rm -rf won't do it:
each file in annex/objects/ is nested inside a
folder with read-only permissions.
The recommended workaround is to run chmod -R +w when
you're sure you actually want to delete a repo. See
https://git-annex.branchable.com/internals/lockdown
So we edit util.RemoveAll() to do just that, so now
it's `chmod -R +w && rm -rf` instead of just `rm -rf`.

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>

1. Fix the typo `BlockingByDependenciesNotPermitted`, which causes the
`not permitted message` not to show. The correct one is `Blocking` or
`BlockedBy`
2. Rewrite the perm check. The perm check uses a very tricky way to
avoid duplicate checks for a slice of issues, which is confusing. In
fact, it's also the reason causing the bug. It uses `lastRepoID` and
`lastPerm` to avoid duplicate checks, but forgets to assign the
`lastPerm` at the end of the code block. So I rewrote this to avoid this
trick.
3. It also reuses the `blocks` slice, which is even more confusing. So I
rewrote this too.

Since https://gitea.com/xorm/xorm/pulls/2383 merged, xorm now supports
UPDATE JOIN.
To keep consistent from different databases, xorm use
`engine.Join().Update`, but the actural generated SQL are different
between different databases.
For MySQL, it's `UPDATE talbe1 JOIN table2 ON join_conditions SET xxx
Where xxx`.
For MSSQL, it's `UPDATE table1 SET xxx FROM TABLE1, TABLE2 WHERE
join_conditions`.
For SQLITE per https://www.sqlite.org/lang_update.html, sqlite support
`UPDATE table1 SET xxx FROM table2 WHERE join conditions` from
3.33.0(2020-8-14).
