e0c1abc5fe fix(sqlite): apply options (#10049)
@calmh it seems `sqlite.Open` forgets to apply options supplied to it
(currently only the delete retention interval).

8372c0288f fix(gui): mark unseen disconnected devices as inactive (#10048)
Currently, the "Disconnected (Inactive)" status is only given to devices
that have not been seen for 7 days or longer. However, this is not the
case when adding a new device, or after resetting the database. Those
devices are only marked as "Disconnected", and they will stay like that
even if a long time passes without any connectivity. Moreover, the lack
of an "Inactive" status may confuse the user to believe that their
disconnect is only temporary.

For this reason, always mark devices that have not been seen yet as
"Disconnected (Inactive)".

d23cd197e1 chore(fs): changes to allow Filesystem to be implemented externally (#10040)
### Purpose

The `fs.Filesystem` interface contains two parts that cannot be
implemented externally because they are private:

* `filesystemWrapperType`: this PR changes `unwrapFilesystem` to
downcast to a specific concrete type
* `underlying`: this PR simply moves it to an unexported interface

### Testing

Regular tests pass.

c9650fc7d5 chore(model): delay starting a pull while there are incoming index updates (#10041)
This adds a simple delay to the process for starting the pull, by
default one second. In practice this means we're likely to wait for
initial index transfer, or multiple messages sent as part of a larger
change. This is better because we're more likely to have the whole
change for the purpose of handling renames etc, and also it's more
efficient to do one larger puller iteration instead of multiple while
also processing changes.

It does however introduce a certain amount of delay into the sync
process, so it can be tuned down or turned off entirely.

cf1cf85ce6 chore(db): use one SQLite database per folder (#10042)
This changes the database structure to use one database per folder, with
a small main database to coordinate. Reverts the prior change to buffer
all files in memory when pulling, meaning there is now a phase where the
WAL file will grow significantly, at least for initial sync of folders
with many directories.

6bc2784e9a build: replace underscore in Debian version (#10032)
The workflow building Debian packages chokes on branches containing
underscores:

```
{:timestamp=>"2025-04-03T10:31:46.749835+0000", :message=>"Invalid package configuration: The version looks invalid for Debian packages. Debian version field must contain only alphanumerics and . (period), + (plus), - (hyphen) or ~ (tilde). I have '1.29.5~dev.13.ga38df11f~srv_stun' which which isn't valid.", :level=>:error}
```

This replaces the offending `_` with a `~` which should yield a valid
version.

86cbc2486f chore: forget deleted files older than six months (fixes #6284) (#10023)
This reduces the number of file entries we carry in the database,
sometimes significantly. The downside is that if a file is deleted while
a device is offline, and that device comes back more than the cutoff
interval (six months) later, those files will get resurrected at some
point.

0bcc31d058 chore(db): increase journal limit to 64MiB (#10022)
The current limit is far too low for our workloads. Perhaps we should
aim even higher than the 64MiB this patch proposes?

Citing the sqlite docs:

> [...] after committing a transaction the rollback journal file may
remain in the file-system. **This increases performance for subsequent
transactions since overwriting an existing file is faster than append to
a file**, but it also consumes file-system space.

tl;dr: if the limit is too low, we're shooting ourselves in the foot in
terms of performance.

a99e670ebb chore: harmonise command line flags (#10007)
(v2 change)

This cleans up the command line parsing a little:
- Remove the hack for supporting legacy single-dash long options (e.g.
`-home`), thus enabling actual short options
- Move legacy imperative flags from under the serve command into
separate commands, e.g. `syncthing serve --paths` to see the paths list
is now `syncthing paths`, `syncthing --upgrade-check` is now `syncthing
upgrade --check`
- Add environment variable support for all remaining flags for the
`serve` command (with one exception, left for the reader to discover),
as these are now all modifiers and not imperative

```

I think the `+7%` for the lowercase Latin1 testcase is easily outweighed
by the ASCII and unicode improvements 🙂

1efcfeb3ad chore(config): remove discontinued secondary STUN servers (fixes #10011) (#10012)
Similarly to #10009, we will remove some discontinued STUN servers,
except instead of being the official primary server, it's some
unofficial secondary STUN servers.

### Testing

Use a STUN client (like [`pystun3`](https://pypi.org/project/pystun3))
to probe that the removed STUN servers are inactive.

6085e3a5eb fix(stun): better error handling (ref #10008) (#10010) 2025-03-30 11:56:29 -07:00

e5b72da607 fix(config): remove discontinued primary STUN server (fixes #10008) (#10009)
The mechanism for primary STUN servers, is still intact, in case this
gets retried with a different domain.

### Purpose

As seen in [stun.syncthing.net doesn’t resolve
anymore](https://forum.syncthing.net/t/stun-syncthing-net-doesnt-resolve-anymore/24075/2?u=marbens)
on the forums, stun.syncthing.net has been shut down, so I think it's
probably a good idea to remove it.

### Testing

1. Have two or more devices
2. Disable Relaying
3. Have no Internet ports open on either end for incoming connections
trigger STUN)
4. Enable the `stun` debugging facility in the Actions -> Logs ->
Debugging Facilities
5. Verify that it doesn't output something like this within a few
seconds:
```
2025-03-30 05:51:32 Enabled debug data for "stun"
2025-03-30 05:51:47 Starting stun for Stun@udp://[::]:22000
2025-03-30 05:51:47 Running stun for Stun@udp://[::]:22000 via stun.syncthing.net:3478
2025-03-30 05:51:47 Stun@udp://[::]:22000 stun addr resolution on stun.syncthing.net:3478: lookup stun.syncthing.net: no such host
```

0d6117d585 fix(gui): validate device ID in canonical form (fixes #7291) (#10006)
### Purpose

In the GUI, the device ID validation was case-sensitive and didn’t
account for dash variations, which allowed users to enter an existing
device ID without receiving proper feedback.

This fix ensures the ID is validated in its canonical form, thus
preventing the user from submitting the request if the device ID already
exists.

### Testing

To test this change, try adding a new device with an ID that matches an
existing device, but with a different case or dashes.

b1c8f88a44 chore: remove weak hashing which does not pull its weight (#10005)
We've had weak/rolling hashing in the code for quite a while. It was a
popular request for a while, based on the belief that rsync does this
and we should too. However, the benefit is quite small; we save on
average about 0.8% of transferred blocks over the population as a whole:

<img width="974" alt="Screenshot 2025-03-28 at 17 09 02"
src="https://github.com/user-attachments/assets/bbe10dea-f85e-4043-9823-7cef1220b4a2"
/>

This would be fine if the cost was comparably low, however the downside
of attempting rolling hash matching is that we (by default) do a
complete file read on the destination in order to look for matches
before we starting pulling blocks for the file. For any larger file this
means a sometimes long, I/O-intensive pause before the file starts
syncing, for usually no benefit.

I propose we simply rip off the bandaid and save the effort.

629971687d feat(gui): explanation to options enabled or disabled per folder type (#9367)
Currently, some options are automatically enabled or disabled depending
on the folder type. However, there is no explanation in the GUI on why
the options are like that. Thus, add short explanatory notes to each
case, where the option is either disabled or enabled according to the
current folder type.

3c955a9706 chore(lib): expose model methods to obtain progress (#9886)
### Purpose

This exposes four methods from `Model` through `Internals`. It allows
apps like Synctrain to obtain information about local/remote need and
sync progress.

### Testing

No testing seems necessary, functions are exported verbatim.

### Screenshots

N/a

### Documentation

Not public API, I am aware this interface may change at any time.

## Authorship

OK.
