- 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
The keying modules tries to solve two problems, the lack of key
separation and the lack of AEAD being used for encryption. The currently
used `secrets` doesn't provide this and is hard to adjust to provide
this functionality.
For encryption, the additional data is now a parameter that can be used,
as the underlying primitive is an AEAD constructions. This allows for
context binding to happen and can be seen as defense-in-depth; it
ensures that if a value X is encrypted for context Y (e.g. ID=3,
Column="private_key") it will only decrypt if that context Y is also
given in the Decrypt function. This makes confused deputy attack harder
to exploit.[^1]
For key separation, HKDF is used to derives subkeys from some IKM, which
is the value of the `[service].SECRET_KEY` config setting. The context
for subkeys are hardcoded, any variable should be shuffled into the the
additional data parameter when encrypting.
[^1]: This is still possible, because the used AEAD construction is not
key-comitting. For Forgejo's current use-case this risk is negligible,
because the subkeys aren't known to a malicious user (which is required
for such attack), unless they also have access to the IKM (at which
point you can assume the whole system is compromised). See
https://scottarc.blog/2022/10/17/lucid-multi-key-deputies-require-commitment/
One method to set them all... or something like that.
The defaults for git-grep options were scattered over the run
function body. This change refactors them into a separate method.
The application of defaults is checked implicitly by existing
tests and linters, and the new approach makes it very easy
to inspect the desired defaults are set.
The forgejo/forgejo#2367 pull requests added rel="nofollow" on filters in the
menu, this commit adds it on the labels in the listing and a few other places.
We need to shorten the timeout to bound effectively for
computation size. This protects against "too big" repos.
This also protects to some extent against too long lines
if kept to very low values (basically so that grep cannot run out
of memory beforehand).
Docs-PR: forgejo/docs#812
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.

Conflicts:
trivial resolution because go-git support was dropped https://codeberg.org/forgejo/forgejo/pulls/4941
Support compression for Actions logs to save storage space and
bandwidth. Inspired by
https://github.com/go-gitea/gitea/issues/24256#issuecomment-1521153015
The biggest challenge is that the compression format should support
[seekable](https://github.com/facebook/zstd/blob/dev/contrib/seekable_format/zstd_seekable_compression_format.md).
So when users are viewing a part of the log lines, Gitea doesn't need to
download the whole compressed file and decompress it.
That means gzip cannot help here. And I did research, there aren't too
many choices, like bgzip and xz, but I think zstd is the most popular
one. It has an implementation in Golang with
[zstd](https://github.com/klauspost/compress/tree/master/zstd) and
[zstd-seekable-format-go](https://github.com/SaveTheRbtz/zstd-seekable-format-go),
and what is better is that it has good compatibility: a seekable format
zstd file can be read by a regular zstd reader.
This PR introduces a new package `zstd` to combine and wrap the two
packages, to provide a unified and easy-to-use API.
And a new setting `LOG_COMPRESSION` is added to the config, although I
don't see any reason why not to use compression, I think's it's a good
idea to keep the default with `none` to be consistent with old versions.
`LOG_COMPRESSION` takes effect for only new log files, it adds `.zst` as
an extension to the file name, so Gitea can determine if it needs
decompression according to the file name when reading. Old files will
keep the format since it's not worth converting them, as they will be
cleared after #31735.

(cherry picked from commit 94cca8846e7d62c8a295d70c8199d706dfa60e5c)
There is no reason to reject initial dashes in git-grep
expressions... other than the code not supporting it previously.
A new method is introduced to relax the security checks.
- When people click on the logout button, a event is sent to all
browser tabs (actually to a shared worker) to notify them of this
logout. This is done in a blocking fashion, to ensure every registered
channel (which realistically should be one for every user because of the
shared worker) for a user receives this message. While doing this, it
locks the mutex for the eventsource module.
- Codeberg is currently observing a deadlock that's caused by this
blocking behavior, a channel isn't receiving the logout event. We
currently don't have a good theory of why this is being caused. This in
turn is causing that the logout functionality is no longer working and
people no longer receive notifications, unless they refresh the page.
- This patchs makes this message non-blocking and thus making it
consistent with the other messages. We don't see a good reason why this
specific event needs to be blocking and the commit introducing it
doesn't offer a rationale either.
See https://codeberg.org/forgejo/discussions/issues/164 for the
rationale and discussion of this change.
Everything related to the `go-git` dependency is dropped (Only a single
instance is left in a test file to test for an XSS, it requires crafting
an commit that Git itself refuses to craft). `_gogit` files have
been removed entirely, `go:build: !gogit` is removed, `XXX_nogogit.go` files
either have been renamed or had their code being merged into the
`XXX.go` file.
It is a waste of resources to scan them looking for matches
because they are never returned back - they appear as empty
lines in the current format.
Notably, even if they were returned, it is unlikely that matching
in binary files makes sense when the goal is "code search".
Analogously to how it happens for MaxResultLimit.
The default of 20 is inspired by a well-known, commercial code
hosting platform.
Unbounded limits are risky because they expose Forgejo to a class
of DoS attacks where queries are crafted to take advantage of
missing bounds.
Previous arch package grouping was not well-suited for complex or multi-architecture environments. It now supports the following content:
- Support grouping by any path.
- New support for packages in `xz` format.

Provide a bit more journald integration. Specifically:
- support emission of printk-style log level prefixes, documented in [`sd-daemon`(3)](https://man7.org/linux/man-pages/man3/sd-daemon.3.html#DESCRIPTION), that allow journald to automatically annotate stderr log lines with their level;
- add a new "journaldflags" item that is supposed to be used in place of "stdflags" when under journald to reduce log clutter (i. e. strip date/time info to avoid duplication, and use log level prefixes instead of textual log levels);
- detect whether stderr and/or stdout are attached to journald by parsing `$JOURNAL_STREAM` environment variable and adjust console logger defaults accordingly.

- Fixes an XSS that was introduced in
https://codeberg.org/forgejo/forgejo/pulls/1433
- This XSS allows for `href`s in anchor elements to be set to a
`javascript:` uri in the repository description, which would upon
clicking (and not upon loading) the anchor element execute the specified
javascript in that uri.
- [`AllowStandardURLs`](https://pkg.go.dev/github.com/microcosm-cc/bluemonday#Policy.AllowStandardURLs) is now called for the repository description
policy, which ensures that URIs in anchor elements are `mailto:`,
`http://` or `https://` and thereby disallowing the `javascript:` URI.
It also now allows non-relative links and sets `rel="nofollow"` on
anchor elements.
- Unit test added.

Was facing issues while writing unit tests for federation code. Mocks weren't catching all network calls, because was being out of scope of the mocking infra. Plus, I think we can have more granular tests.
This PR puts the client behind an interface, that can be retrieved from `ctx`. Context doesn't require initialization, as it defaults to the implementation available in-tree. It may be overridden when required (like testing).
## Mechanism
1. Get client factory from `ctx` (factory contains network and crypto parameters that are needed)
2. Initialize client with sender's keys and the receiver's public key
3. Use client as before.

- If you have the external issue setting enabled, any reference would
have been rendered as an external issue, however this shouldn't be
happening to references that refer to issues in other repositories.
- Unit test added.
Mastodon with `AUTHORIZED_FETCH` enabled requires the `Host` header to
be signed too, add it to the default for `setting.Federation.GetHeaders`
and `setting.Federation.PostHeaders`.
For this to work, we need to sign the request later: not immediately
after `NewRequest`, but just before sending them out with `client.Do`.
Doing so also lets us use `setting.Federation.GetHeaders` (we were using
`.PostHeaders` even for GET requests before).

Fix #31137.
Replace #31623#31697.
When migrating LFS objects, if there's any object that failed (like some
objects are losted, which is not really critical), Gitea will stop
migrating LFS immediately but treat the migration as successful.
This PR checks the error according to the [LFS api
doc](https://github.com/git-lfs/git-lfs/blob/main/docs/api/batch.md#successful-responses).
> LFS object error codes should match HTTP status codes where possible:
>
> - 404 - The object does not exist on the server.
> - 409 - The specified hash algorithm disagrees with the server's
acceptable options.
> - 410 - The object was removed by the owner.
> - 422 - Validation error.
If the error is `404`, it's safe to ignore it and continue migration.
Otherwise, stop the migration and mark it as failed to ensure data
integrity of LFS objects.
And maybe we should also ignore others errors (maybe `410`? I'm not sure
what's the difference between "does not exist" and "removed by the
owner".), we can add it later when some users report that they have
failed to migrate LFS because of an error which should be ignored.
