### Testing
I have not been able to reproduce the panic throughout a few minutes of
continuously running the test without this fix, but judging by the
traceback it seems to only happen if the test happens to delete the
folder from config at the same time `scanTimerFired` triggers.
### Purpose
Syncthing had a healthcheck API for a while, and the example Dockerfile
for it has it in the form of:
HEALTHCHECK --interval=1m --timeout=10s \
CMD curl -fkLsS -m 2 127.0.0.1:8384/rest/noauth/health | grep -o
--color=never OK || exit 1
Let's add it to the docker-compose as well
### Testing
I use this docker-compose.yml file to deploy via ansible (using
community.docker.docker_compose_v2) to my machine with success, using
`wait: true` in ansible for it to use `docker compose up --wait`.
```yml
- name: Enable syncthing docker
community.docker.docker_compose_v2:
project_src: /srv/syncthing
wait: true
wait_timeout: 90
```
In ignores, normalize the input when parsing it.
When scanning, normalize earlier such that the path is already
normalized when checking ignores. This requires splitting normalization
of the string from normalization of the file, as we don't want to
attempt the latter if the file is ignored.

There was a bug that the unique ID was not set when reporting was
enabled, and thus the reports where rejected by the server. The unique
ID got set only on startup, so next time Syncthing restarted.
This makes sure to set the unique ID when blank.
I can see already in our Sentry data that there are a fair amount of
these warnings, and mostly the shape of it. Asking users to report them
will likely cause a lot of reporting effort to fairly little additional
value. We can do that when/if we have something more targeted to ask
for.
This codifies a review policy which is closer to what I always
envisioned, but which isn't expressible using the normal checks in the
GitHub GUI. It would move the commit approval check from GitHub into the
policy-bot check which is already present to enforce the
conventional-commits standard. Approvals in general would still work the
same -- it's just that the bot picks it up and toggles the status
accordingly. From a GitHub side when this is enabled we'd remove the
requires-review check from there and let the bot decide that part. We
would still require builds and tests to pass of course.
There are a couple of relexations from the current policy, details in
the code but briefly:
- Changes to translations or dependencies by a trusted person don't
require review
- Trivial changes by a trusted person, explicitly marked as such, don't
require review
This enables less bureaucracy for things like adding new translated
languages and updating dependencies, and enables the trivial-change
workflow to a larger audience than, like, me, who could always just
bypass the rules by way of being admin.
### Purpose
Since #8757, the Syncthing GUI now has an unauthenticated state. One
consequence of this is that `$scope.versionBase()` is not initialized
while unauthenticated, which causes the `docsURL` function to truncate
links to just `https://docs.syncthing.net`/, discarding the section
path. This currently affects at least the "Help > Introduction" link
reachable both while logged in and not. The issue is exacerbated in
https://github.com/syncthing/syncthing/pull/9175 where we sometimes want
to show additional contextual help links from the login page to
particular sections of the docs.
I don't think it's any worse to try to preserve the section path even
without an explicit version tag, than to fall back to just the host and
lose all context the link was attempting to provide.
### Testing
- On commit b1ed2802fb (before):
- Open the GUI, set a username and log out.
- Open the "Help" drop-down. The "Introduction" item links to:
https://docs.syncthing.net/
- Log in.
- Open the "Help" drop-down. The "Introduction" item links to:
https://docs.syncthing.net/v1.27.10/intro/gui
- On commit 44fef317800ce1d0795b4e2ebfbd5e9deda849ef (after):
- Open the GUI, set a username and log out.
- Open the "Help" drop-down. The "Introduction" item links to:
https://docs.syncthing.net/intro/gui
- Log in.
- Open the "Help" drop-down. The "Introduction" item links to:
https://docs.syncthing.net/v1.27.10/intro/gui
### Screenshots
This is a GUI change, but affecting only URLs in the markup with no
visual changes.
### Drawbacks
If a `docsURL` call generates a versionless link to a docs page that
doesn't exist on https://docs.syncthing.net - presumably because
Syncthing is not the latest version and links to a deleted page? - then
this will lead to GitHub's generic 404 page with no link to the
Syncthing docs root. Before, any versionless link would also be a
pathless link, leading to the Syncthing docs root instead of a 404 page.
### Purpose
The primary aim of this change is to minimize log clutter in production
environments. There are many lines in the logs coming from an expected
race condition when two devices connect `already connected to this
device`. These messages do not indicate errors and can overwhelm the log
files with unnecessary noise.
By lowering the logging level, we enhance the usability of the logs,
making it easier for users and developers to identify actual issues
without being distracted
### Testing
1. Build syncthing locally
2. Start two Syncthing instances
```bash
./syncthing -no-browser -home=~/.config/syncthing1
./syncthing -no-browser -home=~/.config/syncthing2
```
3. Enable the DEBUG logs from UI for `connections` package
4. Connect the synching instances by adding remote devices from the UI
5. Observe the logs for the message `XXXX already connected to this
device`

Move infrastructure related commands to under `cmd/infra` and
development stuff to `cmd/dev`. The default build command builds the
regular user facing binaries: syncthing, stdiscosrv, and strelaysrv.
Reasoning in comments. The main motivation is to avoid all the case
checks when walking the filesystem.
"again" as we already tried once, but it caused a major issue ragarding
mtimefs layer. The root of this problem has been fixed in the meantime
in ac8b3342a
* infrastructure:
chore(stdiscosrv): ensure incoming addresses are sorted and unique
chore(stdiscosrv): use zero-allocation merge in the common case
chore(stdiscosrv): properly clean out old addresses from memory
chore(stdiscosrv): calculate IPv6 GUA
The read/write loops may keep going for a while on a closing connection
with lots of read/write activity, as it's random which select case is
chosen. And if the connection is slow or even broken, a single
read/write
can take a long time/until timeout. Add initial non-blocking selects
with only the cases relevant to closing, to prioritize those.
