Before introducing the service map and using it for folder runners, the
entries in folderCfgs and folderRunners for the same key/folder were
removed under a single lock. Stopping the folder happens separately
before that with just the read lock. Now with the service map stopping
the folder and removing it from the map is a single operation. And that
still happens with just a read-lock. However even with a full lock it’s
still problematic: After the folder stopped, the runner isn’t present
anymore while the folder-config still is and sais the folder isn't
paused.
The index handler in turn looks at the folder config that is not paused,
thus assumes the runner has to be present -> nil deref on the runner.
A better solution might be to push most of these fmut maps into the
folder - they anyway are needed in there. Then there's just a single
map/source of info that's necessarily consistent. That's quite a bit of
work though, and probably/likely there will be corner cases there too.
This reverts commit e477777f49.
In principle, we could have stayed with `~1.21.1`, but `check-latest:
true` apparently checks some cache/manifest/something that is only
periodically refreshed and isn't aware of 1.21.5 yet. So update the
constraints to force an upgrade.
Also the infrastructure images weren't actually using the constraint
since there was no `setup-go` action...
This reduces allocations, in number and in size, while getting extended
attributes. This is mostly noticable when there is a large number of new
files to scan and we're running with the default scanProgressInterval --
then a queue of files is built in-memory, and this queue includes
extended attributes as part of file metadata. (Arguable it shouldn't,
but that's a more difficult and involved change.)
With 1M files to scan, each with one extended attribute, current peak
memory usage looks like this:

LastSeen for a device was only updated when they connected. This now
updates it when they disconnect, so that we remember the last time we
actually saw them. When asking the API for current stats, currently
connected devices get a last seen value of the current time.
The string is currently hard-coded in English, so allow to translate it
into other languages. It appears mainly in the browser title bar before
logging in into the GUI or when the GUI is still loading.

This adds our short device ID to the basic auth realm. This has at least
two consequences:
- It is different from what's presented by another device on the same
address (e.g., if I use SSH forwards to different dives on the same
local address), preventing credentials for one from being sent to
another.
- It is different from what we did previously, meaning we avoid cached
credentials from old versions interfering with the new login flow.
I don't *think* there should be things that depend on our precise realm
string, so this shouldn't break any existing setups...
Sneakily this also changes the session cookie and CSRF name, because I
think `id.Short().String()` is nicer than `id.String()[:5]` and the
short ID is two characters longer. That's also not a problem...
### Purpose
The OCI image spec specifies well-defined
[annotations](https://github.com/opencontainers/image-spec/blob/main/annotations.md)
that can be added to images.
Theses annotations can then be used by other tools to gather more
information of an image.
This PR adds the `org.opencontainers.image.source` to allow tools such
as [renovate](https://github.com/renovatebot/renovate) to find the
release notes of a give version.
~~I've only done this change for `Dockerfile`. Should I also add the
label to the other dockerfiles?~~
I've now added the source annotations to all `Dockerfile`s & action
workflows.
### Testing
None, change was done by following the [renovate
documentation](https://docs.renovatebot.com/modules/datasource/docker/).
Following up on #9192, this makes use of the new mechanism for the theme
names.
The dummy string added for testing is removed again here. All
translations are updated to the new nested syntax, except Chinese
(zh-HK) where the string weren't actually translated.
Some translations, especially single words or other short
labels for buttons and the like, may not be transferable between
contexts even if they happen to be equal in English. In these cases,
setting an explicit translation ID is important for context separation.
Angular Translate also supports nested JSON in translation tables,
addressed using `.` as namespace separator; this enhancement makes use
of this when extracting translation with an explicit translation ID.
We use `env.GO_VERSION` as cache key for the build cache, but this is
nowadays typically something like `~1.21.1` which doesn't change when
1.21.2, 1.21.3 etc are released, making the cache fairly useless as
everything gets rebuilt. This re-sets the `GO_VERSION` variable after
installing Go so that it contains the actual installed version.
### Purpose
Treat X-Forwarded-For as a comma-separated string to prevent nil IP being returned by the Discovery Server
### Testing
Unit Tests implemented
Testing with a Discovery Client can be done as follows:
```
A simple example to replicate this entails running Discovery with HTTP, use Nginx as a reverse proxy and hardcode (as an example) a list of IPs in the X-Forwarded-For header.
1. Send an Announcement with tcp://0.0.0.0:<some-port>
2. Query the DeviceID
3. Observe the returned IP Address is no longer nil; i.e. `tcp://<nil>:<some-port>`
```
Add an id attribute to the submit button shown on the login form. This
allows my password manager's form filling function to interact with the
button after filling in username and password (which already have the id
attribute in place).
This makes the new default $XDG_STATE_HOME/syncthing or
~/.local/state/syncthing, while still looking in legacy locations first
for existing installs.
Note that this does not *move* existing installs, and nor should we.
Existing paths will continue to be used as-is, but the user can move the
dir into the new place if they want to use it (as they could prior to
this change as well, for that matter).
### Documentation
Needs update to the config docs about our default locations.
lib/fs: Fix conflicts on Android due to fluctuating inode change time
[1] added inode change time to file info in order to support syncing
extended attributes. However, in the case of Android, this inode change
time fluctuates, leading to unexpected conflicts even when the user has
not even touched the files on the Android device itself. Thus, in order
to prevent those conflicts from happening, do not write inode change
time on Android.
