This makes a couple of small improvements to the folder summary
mechanism:
- The folder summary includes the local and remote sequence numbers in
clear text, rather than some odd sum that I'm not sure what it was
intended to represent.
- The folder summary event is generated when appropriate, regardless of
whether there is an event listener. We did this before because
generating it was expensive, and we wanted to avoid doing it
unnecessarily. Nowadays, however, it's mostly just reading out
pre-calculated metadata, and anyway, it's nice if it shows up reliably
when running with -verbose.
The point of all this is to make it easier to use these events to judge
when devices are, in fact, in sync. As-is, if I'm looking at two
devices, it's very difficult to reliably determine if they are in sync
or not. The reason is that while we can ask device A if it thinks it's
in sync, we can't see if the answer is "yes" because it has processed
all changes from B, or if it just doesn't know about the changes from B
yet. With proper sequence numbers in the event we can compare the two
and determine the truth. This makes testing a lot easier.
This is a refactor of the protocol/model interface to take the actual
message as the parameter, instead of the broken-out fields:
```diff
type Model interface {
// An index was received from the peer device
- Index(conn Connection, folder string, files []FileInfo) error
+ Index(conn Connection, idx *Index) error
// An index update was received from the peer device
- IndexUpdate(conn Connection, folder string, files []FileInfo) error
+ IndexUpdate(conn Connection, idxUp *IndexUpdate) error
// A request was made by the peer device
- Request(conn Connection, folder, name string, blockNo, size int32, offset int64, hash []byte, weakHash uint32, fromTemporary bool) (RequestResponse, error)
+ Request(conn Connection, req *Request) (RequestResponse, error)
// A cluster configuration message was received
- ClusterConfig(conn Connection, config ClusterConfig) error
+ ClusterConfig(conn Connection, config *ClusterConfig) error
// The peer device closed the connection or an error occurred
Closed(conn Connection, err error)
// The peer device sent progress updates for the files it is currently downloading
- DownloadProgress(conn Connection, folder string, updates []FileDownloadProgressUpdate) error
+ DownloadProgress(conn Connection, p *DownloadProgress) error
}
```
(and changing the `ClusterConfig` to `*ClusterConfig` for symmetry;
we'll be forced to use all pointers everywhere at some point anyway...)
The reason for this is that I have another thing cooking which is a
small troubleshooting change to check index consistency during transfer.
This required adding a field or two to the index/indexupdate messages,
and plumbing the extra parameters in umpteen changes is almost as big a
diff as this is. I figured let's do it once and avoid having to do that
in the future again...
The rest of the diff falls out of the change above, much of it being in
test code where we run these methods manually...
gui: Remove non-functional HTML from External Versioning tooltip (ref
#8923)
Since [1], it is no longer possible to use HTML in tooltips. This was
addressed in [2], however the commit missed one instance of HTML that
was used to change the font type of the External versioning command
tooltip. This remaining HTML is removed in this commit.

This improves the ignore handling so that directories can be fully
ignored (skipped in the watcher) in more cases. Specifically, where the
previous rule was that any complex `!`-pattern would disable skipping
directories, the new rule is that only matches on patterns *after* such
a `!`-pattern disable skipping. That is, the following now does the
intuitive thing:
```
/foo
/bar
!whatever
*
```
- `/foo/**` and `/bar/**` are completely skipped, since there is no
chance anything underneath them could ever be not-ignored
- `!whatever` toggles the "can't skip directories any more" flag
- Anything that matches `*` can't skip directories, because it's
possible we can have `whatever` match something deeper.
To enable this, some refactoring was necessary:
- The "can skip dirs" flag is now a property of the match result, not of
the pattern set as a whole.
- That meant returning a boolean is not good enough, we need to actually
return the entire `Result` (or, like, two booleans but that seemed
uglier and more annoying to use)
- `ShouldIgnore(string) boolean` went away with
`Match(string).IsIgnored()` being the obvious replacement (API
simplification!)
- The watcher then needed to import the `ignore` package (for the
`Result` type), but `fs` imports the watcher and `ignore` imports `fs`.
That's a cycle, so I broke out `Result` into a package of its own so
that it can be safely imported everywhere in things like `type Matcher
interface { Match(string) result.Result }`. There's a fair amount of
stuttering in `result.Result` and maybe we should go with something like
`ignoreresult.R` or so, leaving this open for discussion.
Tests refactored to suit, I think this change is in fact quite well
covered by the existing ones...
Also some noise because a few of the changed files were quite old and
got the `gofumpt` treatment by my editor. Sorry not sorry.

### Purpose
Fix#9241 by expanding tildes in version paths.
When creating the versioner file system, first try to expand any leading
tildes to the user's home directory before handling relative paths. This
makes a version path `"~/p"` expand to `"$HOME/p"` instead of
`"/folder/~/p"`.
### Testing
Added a test to lib/versioner that exercises this code path. Also
manually tested with local syncthing instances.
### Purpose
This PR changes behaviour of syncthing related to `receive-only`
folders, which I believe to be a bug since I wouldn't expect the current
behaviour. With the current syncthing codebase, a file of a
`receive-only` folder that is only modified locally can cause the
creation of a `.sync-conflict` file.
### Testing
Consider this szenario: Setup two paired clients that sync a folder with
a given file (e.g. `Test.txt`). One of the clients configures the folder
to be `receive-only`. Now, change the contents of the file for the
receive-only client **_twice_**.
With the current syncthing codebase, this leads to the creation of a
`.sync-conflict` file that contains the modified contents, while the
regular `Test.txt` file is reset to the cluster's provided contents.
This is due to a `protocol.FileInfo#ShouldConflict` check, that is
succeeding on the locally modified file.
This PR changes this behaviour to not reset the file and not cause the
creation of a `.sync-conflict`. Instead, the second content update is
treated the same as the first content update.
This PR also contains a test that fails on the current codebase and
succeeds with the changes introduced in this PR.
### Screenshots
This is not a GUI change
### Documentation
This is not a user visible change.
## Authorship
Your name and email will be added automatically to the AUTHORS file
based on the commit metadata.
#### Thanks to all the syncthing folks for this awesome piece of
software!
### Purpose
This implements CLI completion using the Kongplete module. As a side
effect a CLI structure for syncthing/cli was created for kongplete to be
able to parse and implement CLI completion.
### Testing
I've tested the autocompletion manually, and it had worked, but I hadn't
added any tests so as to test it automatically. Additionally, I ran `go
run build.go test` with all tests passing.
This adds a "token manager" which handles storing and checking expired
tokens, used for both sessions and CSRF tokens. It removes the old,
corresponding functionality for CSRFs which saved things in a file. The
result is less crap in the state directory, and active login sessions
now survive a Syncthing restart (this really annoyed me).
It also adds a boolean on login to create a longer-lived session cookie,
which is now possible and useful. Thus we can remain logged in over
browser restarts, which was also annoying... :)

Best viewed with whitespace-insensitive diff, as a bunch of the auth
functions became methods instead of closures which changed indentation.
```
% export GOTOOLCHAIN=go1.20.7
% go list -m all | cut -d ' ' -f 1 | xargs go get -u
% go mod tidy

Except:
- github.com/jackpal/gateway now requires Go 1.21
- github.com/shirou/gopsutil breaks linux-mips in latest version
Currently, with a large number of versioned files, there is a delay
between the Restore Versions modal showing up on the screen and
initialisation of the actual versions tree. This leads to a situation,
where the modal is initially empty, which confuses the user, making
them think that something is not working correctly.
To avoid the above, always show the loading data information. The string
is displayed using static HTML first, and then replaced with the exact
same content once the tree has been initialised. Both elements use the
same style and position, so there is no visual shift between the two.

If syncOwnership is enabled and the remote uses for example a dockerized
Syncthing it can't fetch the ownername and groupname of the local
instance. Without this patch this led to an endless cycle of detected
changes on the remote and failing re-sync attempts.
This patch skips comparing the ownername and groupname if they zare empty
on one side.
See https://github.com/syncthing/syncthing/issues/9039 for details.
### Testing
Proposed by @calmh in
https://github.com/syncthing/syncthing/issues/9039#issuecomment-1870584783
and tested locally in my setup,
Setup PC 1:
- Syncthing is run in Docker as user `root` and has none of the users
configured that synchronize their files
Setup PC 2:
- this PC has all users locally setup
- Syncthing runs as `systemd` service as user `syncthing` and has
multiple capabilities set to set the correct owner and permissions
Setup PC 3:
- same as PC 2
Handling:
- `PC 1` is send & receive and uses just the `UID` and `GID` identifiers
to store the files
- `PC 2` and `PC 3` synchronize their files over `PC 1` but not directly
to each other
Outcome:
- `PC 2` and `PC 3` should send and receive their files with the correct
ownership and groups from `PC 1`
### Purpose
Instead of hardcoding `SigningKey` as text use `go:embed`. Fixes#9247.
### Testing
* Building syncthing
* Trying to upgrade (signature verification)
On kqueue-systems, folders listen for folder summaries to (be able to)
warn for potential high resource usage. However, it listened for any
folder summary and not for the summary which matches the folder it's
about. This could cause that an unwatched folder causes a folder summary
containing more files than the threshold (10k), and the listening folder
(with the watcher enabled) triggers the warning.
This makes sure that only the folder summaries which are relevant to the
specific folder are being handled.
### Testing
- Fire up some kqueue-system (freebsd, I used).
- add folder A, disable the watcher, add 10001 files
- add folder B with the watcher enabled, no files are needed here
Before the change:
- add an item to folder A, trigger a rescan to speed up the process
- wait some seconds...warning triggered by folder B's
summarySubscription
After the change:
- Only a warning is triggered if the received folder summary matches the
folder which listens for the summaries
Cleanup after #9275.
This renames `fmut` -> `mut`, removes the deadlock detector and
associated plumbing, renames some things from `...PRLocked` to
`...RLocked` and similar, and updates comments.
Apart from the removal of the deadlock detection machinery, no
functional code changes... i.e. almost 100% diff noise, have fun
reviewing.
I'm tired of the fmut/pmut shenanigans. This consolidates both under one
lock; I'm not convinced there are any significant performance
differences with this approach since we're literally just protecting map
juggling...
- The locking goes away when we were already under an appropriate fmut
lock.
- Where we had fmut.RLock()+pmut.Lock() it gets upgraded to an
fmut.Lock().
- Otherwise s/pmut/fmut/.
In order to avoid diff noise for an important change I did not do the
following cleanups, which will be filed in a PR after this one, if
accepted:
- Renaming fmut to just mut
- Renaming methods that refer to being "PRLocked" and stuff like that
- Removing the no longer relevant deadlock detector
- Comments referring to pmut and locking sequences...
`syncthing cli` subcommand was using urfave/cli as the command parser.
This PR replace it with kong, which the main command uses.
Some help texts and error message format are changed. Other than that,
all the command usage and logic remains unchanged.
There's only one place which still uses urfave/cli, which is `syncthing
cli config`, because it uses some magic to dynamically build commands
from struct reflects. I used kong's `passthrough:""` tag to pass any
argument following `syncthing cli config` to urfave/cli parser.
This PR also fixes#9041
