In #9701 there was a change that put the mutex used for `getExpireAdd` directly in `defaultRealCaser`, which is erroneous because multiple filesystems can share the same `caseCache`.
### Purpose
Fixes#9836 and [Slow sync sending files from Android](https://forum.syncthing.net/t/slow-sync-sending-files-from-android/24208?u=marbens). There may be other issues caused by `getExpireAdd` conflicting with itself, though.
### Testing
Unit tests pass and the case cache and conflict detection _seem_ to behave correctly.

Due to a thinko, this optimisation was wildly incorrect and would read
to lack of block reuse when syncing files.

IMHO the logic here was inverted. The only use for the report data is to
show a preview when we ask the user whether they want to participate in

then consider whether we wanted to show that dialog or not. Instead,
only load if it we're going to show the dialog.

This adds a new field to the file information we keep, the "previous
blocks hash". This is the hash of the file contents as it was in its
previous incarnation. That is, every scan that updates the blocks hash
will move the current hash to the "previous" field.
This enables an addition to the conflict detection algorithm: if the
file to be synced is in conflict with the current file on disk
(version-counter wise), but it indicates that it was based on the
precise contents we have (new.prevBlocksHash == current.blocksHash),
then it's not really a conflict.

This changes the files table to use normalisation for the names and
versions. The idea is that these are often common between all remote
devices, and repeating an integer is more efficient than repeating a
long string. A new benchmark bears this out; for a database with 100k
files shared between 31 devices, with some worst case assumption on
version vector size, the database is reduced in size by 50% and the test
finishes quicker:
Current:
db_bench_test.go:322: Total size: 6263.70 MiB
--- PASS: TestBenchmarkSizeManyFilesRemotes (1084.89s)
New:
db_bench_test.go:326: Total size: 3049.95 MiB
--- PASS: TestBenchmarkSizeManyFilesRemotes (776.97s)
The other benchmarks end up about the same within the margin of
variability, with one possible exception being that RemoteNeed seems to
be a little slower on average:
old files/s new files/s
Update/n=RemoteNeed/size=1000-8 5.051k 4.654k
Update/n=RemoteNeed/size=2000-8 5.201k 4.384k

Periodic garbage collection can take a long time on large folders. The worst
step is the one for blocks, which are typically orders of magnitude more
numerous than files or block lists.
This improves the situation in by running blocks GC in a number of smaller
range chunks, in random order, and stopping after a time limit. At most ten
minutes per run will be spent garbage collecting blocklists and blocks.
With this, we're not guaranteed to complete a full GC on every run, but
we'll make some progress and get there eventually.

This adds several options for configuring the log format of timestamps
and severity levels, making it more suitable for integration with log
systems like systemd.
--log-format-timestamp="2006-01-02 15:04:05"
Format for timestamp, set to empty to disable timestamps ($STLOGFORMATTIMESTAMP)
--[no-]log-format-level-string
Whether to include level string in log line ($STLOGFORMATLEVELSTRING)
--[no-]log-format-level-syslog
Whether to include level as syslog prefix in log line ($STLOGFORMATLEVELSYSLOG)
So, to get a timestamp suitable for systemd (syslog prefix, no level
string, no timestamp) we can pass `--log-format-timestamp=""
--no-log-format-level-string --log-format-level-syslog` or,
equivalently, set `STLOGFORMATTIMESTAMP="" STLOGFORMATLEVELSTRING=false
STLOGFORMATLEVELSYSLOG=true`.

Just to be entirely sure that if the migration succeeds the schema
version is always also updated. Currently if a migration succeeds but a
later migration doesn't, the changes of the migration apply but the
version stays - if the migration is breaking/non-idempotent, it will
fail when it tries to rerun it next time (otherwise it's just a
pointless re-execution).
Unfortunately with the current `db.runScripts` it wasn't that easy to
do, so I had to do quite a bit of refactoring. I am also ensuring the
right order of transactions now, though I assume that was already the
case lexicographically - can't hurt to be safe.
Currently, the input field has no step defined, meaning that it can be
increased with the arrow keys by the default value of "1". Considering
the fact that the default value is "3600" (seconds or one hour), it is
unlikely that the user wants to change it with such minimal steps.
For this reason, change the default step to "3600" (one hour). If the
user needs more granual control, they can still input the value
in seconds manually.

This just removes an unnecessary foreign key constraint, where we
already do the garbage collection manually in the database service.
However, as part of getting here I tried a couple of other variants
along the way:
- Changing the order of the primary key from `(hash, blocklist_hash,
idx)` to `(blocklist_hash, idx, hash)` so that inserts would be
naturally ordered. However this requires a new index `on blocks (hash)`
so that we can still look up blocks by hash, and turns out to be
strictly worse than what we already have.
- Removing the primary key entirely and the `WITHOUT ROWID` to make it a
rowid table without any required order, and an index as above. This is
faster when the table is small, but becomes slower when it's large (due
to dual indexes I guess).
These are the benchmark results from current `main`, the second
alternative below ("Index(hash)") and this proposal that retains the
combined primary key ("combined"). Overall it ends up being about 65%
faster.

Ref #10264
Currently, the number of hashers is always set to 1 on interactive
operating systems, which are defined as Windows, macOS, iOS, and
Android. However, with modern multicore CPUs, it does not make much
sense to limit performance so much.
For example, without this fix, a CPU with 16 cores / 32 threads is
still limited to using just a single thread to hash files per folder,
which may severely affect its performance.
For this reason, instead of using a fixed value, calculate the number
dynamically, so that it equals one-fourth of the total number of CPU
cores. This way, the value of hashes will still end up being just 1 on
a slower 4-thread CPU, but it will be allowed to take larger values when
the number of threads is higher, increasing hashing performance in the
process.

Currently, the number of hashers, with the exception of some specific
operating systems or when defined manually, equals the number of CPU
cores divided by the overall number of folders, and it does not take
into account the value of MaxFolderConcurrency at all. This leads to
artificial performance limits even when MaxFolderConcurrency is set to
values lower than the number of cores.
For example, let's say that the number of folders is 50 and
MaxFolderConcurrency is set a value of 4 on a 16-core CPU. With the old
calculation, the number of hashers would still end up being just 1 due
to the large number of folders. However, with the new calculation, the
number of hashers in this case will be 4, leading to better hashing
performance per folder.

This adds a cleanup stage to remove database files for folders that no
longer exist on startup. Folder database files were already removed when
dropping a folder, assuming that the folder database had been opened at
that point. This won't be the case though when a folder is removed from
the config when Syncthing isn't running, or when a folder is dropped and
re-migrated in a restarted migration.
This adds a temporary GUI/API server during the database migration. It
responds with 200 OK and some log output for every request. This serves
two purposes:
- Primarily, for deployments that use the API as a health check, it
gives them something positive to accept during the migration, reducing
the risk of the migration getting killed halfway through and restarted,
thus never completing.
- Secondarily, it gives humans who happen to try to load the GUI some
sort of indication of what's going on.
Obviously, anything that expects a well-formed API response at this
stage is still going to fail. They were already failing though, as we
didn't even listen at this point before.
Two things:
- We could run into a write error, which would block the progress
forever without an error. This because the writer routine exited, while
the reader was just blocked on sending to it.
- After a failed migration, inserts could fail with unique index
constraint errors because we are reusing the sequence numbers from the
original database. Add a drop folder to the start of migration to handle
this.
Additionally, the drop folder will clear out broken database files due
to killed migrations.

This removes the `debugging` bool under GUI configuration, and two no
longer relevant development endpoints: `httpmetrics` (which I can't
imagine anyone using for anything -- if we need such metrics today, the
right place is the Prometheus exported metrics) and the `peerCompletion`
endpoint (previously used by integration tests).
The debugging bool initially enabled just those two endpoints, which are
not for end users. Then we added profiling and support bundles, which
are very useful indeed for end users to access, and they were hidden
behind the same debug flag. I don't see any reason for keeping that flag
now that these methods are more generally useful.

This updates our logging framework from legacy freetext strings using
the `log` package to structured log entries using `log/slog`. I have
updated all INFO or higher level entries, but not yet DEBUG (😓)... So,
at a high level:
There is a slight change in log levels, effectively adding a new warning
level:
- DEBUG is still debug (ideally not for users but developers, though
this is something we need to work on)
- INFO is still info, though I've added more data here, effectively
making Syncthing more verbose by default (more on this below)
- WARNING is a new log level that is different from the _old_ WARNING
(more below)
- ERROR is what was WARNING before -- problems that must be dealt with,
and also bubbled as a popup in the GUI.
A new feature is that the logging level can be set per package to
something other than just debug or info, and hence I feel that we can
add a bit more things into INFO while moving some (in fact, most)
current INFO level warnings into WARNING. For example, I think it's
justified to get a log of synced files in INFO and sync failures in
WARNING. These are things that have historically been tricky to debug
properly, and having more information by default will be useful to many,
while still making it possible get close to told level of inscrutability
by setting the log level to WARNING. I'd like to get to a stage where
DEBUG is never necessary to just figure out what's going on, as opposed
to trying to narrow down a likely bug.
Code wise:
- Our logging object, generally known as `l` in each package, is now a
new adapter object that provides the old API on top of the newer one.
(This should go away once all old log entries are migrated.) This is
only for `l.Debugln` and `l.Debugf`.
- There is a new level tracker that keeps the log level for each
package.
- There is a nested setup of handlers, since the structure mandated by
`log/slog` is slightly convoluted (imho). We do this because we need to
do formatting at a "medium" level internally so we can buffer log lines
in text format but with separate timestamp and log level for the API/GUI
to consume.
- The `debug` API call becomes a `loglevels` API call, which can set the
log level to `DEBUG`, `INFO`, `WARNING` or `ERROR` per package. The GUI
is updated to handle this.
- Our custom `sync` package provided some debugging of mutexes quite
strongly integrated into the old logging framework, only turned on when
`STTRACE` was set to certain values at startup, etc. It's been a long
time since this has been useful; I removed it.
- The `STTRACE` env var remains and can be used the same way as before,
while additionally permitting specific log levels to be specified,
`STTRACE=model:WARN,scanner:DEBUG`.
- There is a new command line option `--log-level=INFO` to set the
default log level.
- The command line options `--log-flags` and `--verbose` go away, but
are currently retained as hidden & ignored options since we set them by
default in some of our startup examples and Syncthing would otherwise
fail to start.

Based on the discussion in
https://forum.syncthing.net/t/towards-syncthing-2-0/24072/35 This PR
adds the ability for Windows users to use the pipe character (|) to
escape the metacharacters *, ?, [, and { in .stignore files.
Additionally, this PR adds the ability for the user to set the escape
character to backslash, or any character they want, by adding a line in
the form:
#escape=X
(where X is any single rune), to the top of an .stignore file.
This would allow users to use the same .stignore file across platforms,
by simply adding
#escape=\
to the top of the file.
### Testing
All tests pass in CI.
### Documentation
See https://github.com/syncthing/docs/pull/919Fixes#10057: Support escaping in .stignore files on Windows
Fixes#7547: Ignore pattern with \[ and \] does not work
Prior to this fix, the folder would only get marked as "syncing" once we
started downloading data from the network. However in some cases there
will be a lot of data that can be reused locally and we spend
significant time copying blocks before downloading anything; in that
case, the folder would appear as "preparing to sync" while it was in
fact moving lots of data.
This fixes that, making it "syncing" as soon as it begins either copying
or downloading data.
### Purpose
Uses recommended pattern for slice pools to avoid copying the slice
struct, suggested by the linter and actually used in the go stdlib, for
example in `net/http/h2_bundle.go`.
Currently, the Revert Local Changes button for Receive Only folders, and
the Delete Unexpected Items button for Receive Encrypted folders buttons
are shown even when the folder is already performing other operations.
Because of the above, pressing the button seems to have no effect, as
its operation can only proceed after the previous operations have
completed. This confuses the user, who then may keep trying to press the
buttons again and again with no visible result.
Therefore, show the two buttons only when the folders are actually idle,
without performing other operations at the same time. This change makes
them behave similarly to the Override Changes button, which is also only
displayed for Send Only folders when they are idle.

We've always, since the introduction of conflicts, had the policy that
deletes lose against any other change, for safety's sake. This is a
problem, however, because it means the sort order of versions is not a
total order.
That is, given two versions `A` and `B` that are currently in conflict,
we will sort them in a given order (let's say `A, B`, so `A < B` for
ordering purposes: we say "A wins over B" or "A is newer than B") and
consider the first in the list the winner. The loser (who has `B` on
disk) will process the conflict at some point and move the file to a
conflict copy and announce `A'` as the resolved conflict. The winner
(with `A` on disk) doesn't do anything.
However, if `A` is deleted the ordering changes. We still have `A < B`
and, of course, `Adel < A` (this is not even a conflict, just linear
order). In most sane systems this would imply the ordering `Adel < A <
B`, however in our case we in fact have `B < Adel` because any version
wins over a deleted one, so there is no logical ordering at all of the
files at this point. `Adel < A < B < Adel ???` In practice the deleted
version may end up at the head or the tail of the list, depending on the
order we do the compares.
Hence, at this point, "whatever" happens and it's not guaranteed to make
any sense. 😬
I propose that we resolve this my simply letting deletes be versions
like anything else and maintain a total ordering based on just version
vectors with the existing tie breakers like always. That means a delete
can win in a conflict situation, and the result should be that the file
is moved to a conflict copy on the losing device. I think this retains
the data safety to almost the same degree as previously, while removing
probably an entire class of strange out of sync bugs...
---
(A potential wrinkle here is that, ideally, we wouldn't even create the
conflict copy when the delete and the losing version represent the same
data -- same as when we handle normal modification conflicts. However,
the deleted FileInfo doesn't carry any information on what the contents
were, so we can't do that right now. A possible future extension would
be to carry the block list hash of the deleted data in the deleted
FileInfo and use that for this purpose, but I don't want to complicate
this PR with that. The block list hash itself also isn't a
protocol-defined thing at the moment, it's something implementation
dependent that we just use locally.)
### Purpose
As discussed on the forum:
https://forum.syncthing.net/t/reviving-nat-pmp-in-v2-x-on-android-14/24554
TL;DR
Android 14+ only lets java code get the gateway IPv4 address which is
used in SyncthingNative’s NAT-PMP feature.
So I’ve added the java code to the wrapper, got the router IP address
and feeded it to SyncthingNative by setting the env var
“FALLBACK_NET_GATEWAY_IPV4”.
This revives the NAT feature:
> [Z36WU] INFO: Detected 1 NAT service
### Testing
Local build and test via Android emulator (AVD 15).
This makes a couple of backwards compatible changes to the
ClusterConfig:
- Remove the `ignore_permissions` and `ignore_delete` booleans which
we've never read or used for anything
- Remove the `disable_temp_indexes` boolean and option entirely. We did
use this one, and about 1% of users have set the option. The only thing
it does is inhibits sending of periodical DownloadProgress messages
while downloading data, which is a minuscule bandwidth optimisation
given that we're already sending data at the time.
- Change the `read_only` boolean (which indicated send-only folders) to
an enum `FolderType`, where the values zero and one match the existing
usage. Again, we don't actually use this value, but I can see that we
might want to and then it makes more sense for it to be more
comprehensive.
- Change the `paused` boolean to an enum `StopReason`, where zero
indicates not stopped and one indicates paused, exactly the same wire
representation as previously but leaves space for additional stop
reasons (errors etc).
### Purpose
Filesystem watcher errors didnt have any whitespace between the share
name and the error message, making it hard to read. A simple colon and
whitespace solves this issue
I lately wanted some photos on my phone, and watched them sync
excrutiatingly slowly. I am used to android being slow, but not that
slow. This restriction caught my eye and I increased it beyond the
limit (didn't spot it at first), and I did see a clear improvement. Of
course as always with such a one-off test, I might also have
hallucinated it, but it seems plausible with the slow thing in android
being some layer between the actual filesystem and apps.
Also increase the max limit, mostly just because I don't see any reason
to restrict it that low - not that I have a particular reason to want
more.
I also changed the xml default to 0: The `prepare` code will change it
to the actual default - no need to change that anymore if we change the
default in the future.
Before:
- Local discovery on Android 10+ is broken. The phone receives local
discovery packets from other devices running Syncthing on the same
network, e.g. a computer. But it doesn't send its own local discovery
packets.
- Startup of the beacon/broadcast.go and beacon/multicast.go "services"
subsequently fail, see the log entries of "service.go" with "2 of 2
failures, backing off".
Root cause:
- Android 10+ restricts determining the network interfaces for privacy
reasons. The interfaces and IP addresses cannot be determined.
- There's a bug in the go "net" library. I can actually get the
interfaces, but the fix was not implemented by the go team.
Workaround:
- The "community" found a workaround by creating a light wrapper around
"net" called "anet" library.
- "anet" adjusts the behaviour on Android 10+ and gets the interfaces
plus their IP addresses, as required by Syncthing.
After:
- By using the "anet" lib, Syncthing is able to get the interface ip
addresses and put them into the "AllAddresses" string array.
- The "AllAddresses" string array is then announced on the local
discovery multicast and broadcast packets, if enabled in Syncthing's
config.
- By correctly getting the interfaces and IP addresses using "anet" in
"beacon/broadcast.go" and "beacon/multicast.go", the services start up
fine again.
Verification:
- I've built "libSyncthingNative.so" with this PR applied for Android
and put it into Syncthing-Fork v1.29.7.5 for testing. My two phones,
Android 10 and Android 15 (arm64-v8a) immediately discovered each other
using local discovery.
- I can see the "sent XX bytes" and "recv XX bytes" on both phones in
the log filtering for "SyncthingNativeCode" :-).
Personal note:
- Please go light on me, and, if it's not demanded too much of your
time, please help me on this. I am no go programmer. Most things you
think are easy or common sense aren't part of my knowledge set. I'd just
like to help and hope we somehow can drive this home together to fix the
problem.

phone can be discovered by other phones running the Syncthing app which
wasn't possible before on Android 10+.

Fixes#7403.
Tested by enabling UPnP on the router, and checking on the router page
that the external ports of the UDP mappings match what is shown in the
logs and the internal ports matching the QUIC listening port.
Only Require either matching UID & GID OR matching Names.
If the 2 devices have a different Name => UID mapping, they can never be
totaly equal. Therefore when syncing we try matching the Name and fall
back to the UID. However when scanning for changes we currently require
both the Name & UID to match. This leads to forever having out of sync
files back and forth, or local additions when receive only.
This patch does not change the sending behavoir. It only change what we
decide is equal for exisiting files with mismapped Name => UID,
The added testcases show the change: Test 1,5,6 are the same as current.
Test 2,3 Are what change with this patch (from false to true). Test 4 is
a subset of test 2 they is currently special cased as true, which does
not chnage.

While it doesn't hurt, it's unnecessary since the big protobuf
modernisation, that also introduced types separate from the generated
ones for internal use. Those fields are already dropped when converting
to the wire in protocol.
This updates our key generation to use Ed25519 keys/certificates for
sync connections. Certificates for browser use remain ECDSA for wider
compatibility.
Ed25519 is more modern and has fewer concerns for the future than the
ECDSA curves we used previously. It is supported from Go 1.13 and
forwards, which is Syncthing 1.3.0 (October 2019).
### Purpose
Locally, on Windows 11, and on the windows-2025 GitHub runner (go 1.23
and 1.24), the `TestCopyRange` test is failing with `The request is not
supported.`
On windows-2022 and windows-2019:
```go
err == syscall.ENOTSUP
```
worked, but on Windows 11 and windows-2025, we need:
```go
errors.Is(err, errors.ErrUnsupported)
```
### Testing
Tested on Windows 11, windows-2019, windows-2022, and
[windows-2025](https://github.com/rasa/syncthing/actions/runs/15525123437/job/43703630634#step:7:2811).

fix(syncthing): avoid writing panic log to nil fd (#10154)
### Purpose
This change fixes a logical bug in the panic log writing where we could
end up writing to a uninitialized file descriptor.
On the very first iteration, `panicFd` is nil. We enter the if `panicFd
== nil { … }` block, check for “panic:” or “fatal error:”, and if
neither matches, we skip instantiating `panicFd` altogether. However,
immediately after, still within `if panicFd == nil { … }`, we call
`panicFd.WriteString("Panic at ...")`. But `panicFd` would in this case
be `nil`, which will cause a run‐time panic.
It's not clear to me why panicFd is only initialized if the lines start
with "panic:" or "fatal error:" so I've left that logic untouched. With
this change we at least avoid the risk of writing to a nil
filedescriptor.

feat(config): expose folder and device info as metrics (fixes#9519) (#10148)
chore: add issue types to GitHub issue templates
build: remove schedule from PR metadata job
chore(protocol): only allow enc. password changes on cluster config (#10145)

Tihs makes it easier to use metrics based on device and folder labels,
names, and other attributes. Other metrics which are based on folder or
device ID can be joined with these info metrics to enrich their label
sets.
```
# HELP syncthing_config_device_info Provides additional information labels on devices
# TYPE syncthing_config_device_info gauge
syncthing_config_device_info{device="I6KAH76-66SLLLB-5PFXSOA-UFJCDZC-YAOMLEK-CP2GB32-BV5RQST-3PSROAU",introducer="false",name="s1",paused="false",untrusted="false"} 1

# TYPE syncthing_config_folder_info gauge
syncthing_config_folder_info{folder="default",label="The default folder",path="s2",paused="false",type="sendreceive"} 1
```
With this you can e.g. query for
```
syncthing_connections_active * on(device) group_left syncthing_config_device_info
```
Fixes#9519Closes#10074Closes#10147
This changes the default number of connections from one to three (one
metadata + two data connections). This should give some advantages of
multiple connections, while also not being an overwhelming change for
larger installations. (Though those may need to tweak their settings
anyway, as always.)
In practice we already always call SetPassword and ClusterConfig
together. However it's not just "sensible" to do that, it's required: If
the passwords change, the remote device needs to know about that to
check that the enc. setup is valid/consistent (e.g. tokens match,
folder-type is appropriate, ...).
And with the passwords set later, there's no point in adding them as
part of creating a new connection.
This is a "followup" (if one can call it that 4 years later :) ) to
resp. fix for the following commit:

Co-authored-by: Jakob Borg <jakob@kastelo.net>
This adds a file that will be prepended to release notes (tag messages,
GitHub releases, forum posts) for v1 releases. I'd like there to be
something there to flag that things are going to change.
* main:
refactor: use slices package for sorting (#10136)
build: handle multiple general release notes
build: no need to build on the branches that just trigger tags
* main:
build: use specific token for pushing release tags
fix(gui): update `uncamel()` to handle strings like 'IDs' (fixes#10128) (#10131)
refactor: use slices package for sort (#10132)
build: process for automatic release tags (#10133)
chore(gui, man, authors): update docs, translations, and contributors
> ⚠️ resubmission targeting `main` instead of `v2`
### Purpose
Updates `uncamel()` function in
[uncamelFilter.js](https://github.com/syncthing/syncthing/blob/v2/gui/default/syncthing/core/uncamelFilter.js)
to fix camelCase conversion edge cases, see #10128
This adds an array called `reservedStrings` which will be printed as-is,
e.g. `IDs`, `LAN` etc. I pre-populated this with what I believe makes
sense, but of course this is easily updated.
### Testing
I compiled all the config variables I could find in
`syncthing/lib/config/*configuration.go` and tested this new function
against them. Everything seemed to pass.
### Screenshot
The sort package is still used in places that were not trivial to
change. Since Go 1.21 slices package can be uswed for sort. See
https://go.dev/doc/go1.21#slices
### Purpose
Make some progress with the migration to a more up-to-date syntax.
* main:
fix(syncthing): ensure both config and data dirs exist at startup (fixes#10126) (#10127)
fix(versioner): fix perms of created folders (fixes#9626) (#10105)
refactor: use slices.Contains to simplify code (#10121)
As suggested in the linked issue, I've updated the versioner code to use
the permissions of the corresponding directory in the synced folder,
when creating the folder in the versions directory
### Testing
- Some tests are included with the PR. Happy to add more if you think
there are some edge-cases that we're missing.
- I've tested manually on linux to confirm the permissions of the
created directories.
- I haven't tested on Windows or OSX (I don't have access to these OS)
The copier routine refactor resulted in bad buffer pool handling,
putting a buffer back into the pool twice. This simplifies and removes
the danger prone Upgrade() method.
### Testing
Change the `auditEnabled` option and you should get a prompt in the Web
GUI.
Restart and change the `auditFile` option, and you should get that same
prompt.
The prompt you should get is shown in the screenshots below.

### Purpose
Setting default configuration was not working properly since the
defaults struct is not deeply copied.
### Testing
Try running commands to change default configuration and either inspect
`config.xml` or `/rest/config` result to see the applied changed.
Example:
```
./syncthing cli config defaults folder versioning params set keep 5
```
* main:
chore(gui, man, authors): update docs, translations, and contributors
feat(gui): close a modal when pressing ESC after switching modal tabs (fixes#9489) (#10092)
Flattened the copier code more. Also removing and moving some
parameters/return values to simplify things. Generally rely less on
return values, e.g. by handling errors right away and using `state` to
do the right thing (e.g. abort on failure).
Supposed to be a refactor without any behaviour changes, except for
fixing a tiny regression on folder order: We used to try copying from
the same folder first, but lost that property at some point (also sent a
PR fixing only that, I'd merge that first making this refactor only).
### Purpose
As stated in #9489 after clicking on a tab link to switch tabs in a
modal you can no longer close the modal through clicking the ESC key
unless you click anywhere on the modal to focus on it again.
### Testing
- Click on a modal that has tabs like "Settings" or "Add Folder" and
switch tabs then click on ESC.
- Check if clicking outside of a modal in the backdrop should still
close the modal.
### Demo
https://github.com/user-attachments/assets/a010db9a-72f7-4160-a7db-ddfebffb4834
Where `folderFilesystems` and `folders` is built, there's a comment
spelling out the purpose: To have the same folder first, as that's the
most likely to get hits. Plus a copy is possibly more efficient than
from another folder, e.g. if that's on a different filesystem. We lost
that behaviour during some unrelated change.
(Also sneaking in a comment fix on yesterdays change.)
This is a draft because I haven't adjusted all the tests yet, I'd like
to get feedback on the change overall first, before spending time on
that.
In my opinion the main win of this change is in it's lower complexity
resp. fewer moving parts. It should also be faster as it only does one
query instead of two, but I have no idea if that's practically
relevant.
This also mirrors the v1 DB, where a block map key had the name
appended. Not that this is an argument for the change, it was mostly
reassuring me that I might not be missing something key here
conceptually (I might still be of course, please tell me :) ).
And the change isn't mainly intrinsically motivated, instead it came
up while fixing a bug in the copier. And the nested nature of that code
makes the fix harder, and "un-nesting" it required me to understand
what's happening. This change fell out of that.
After opening the database, we performed some checks, such as whether
the migration had already been successfully completed. If so, the
function returned immediately, and the database was not closed.

### Purpose
Fix https://github.com/syncthing/syncthing/issues/9336
The `emitLoginAttempt` function now checks for the presence of an
`X-Forwarded-For` header. The IP from this header is only used if the
connecting host is either on loopback or on the same LAN.
In the case of a host pretending to be a proxy, we'd still have both IPs
in the logs, which should make this much less critical from a security
standpoint.
### Testing

2. via proxy an localhost

This cleans up the option to allow old TLS 1.2 sync connections. The
flag existed for compatibility with old Syncthing versions that don't
support TLS 1.3, which is approximately Syncthing 1.2.2 (September 2019)
and older. ("Approximately" because it depends on the Go version it's
built with and that's when we switched to building with Go 1.13.)
Ref #10062 because it reminded me this exists.

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)".

### 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.
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.
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.

fix(config): properly apply defaults when reading folder configuration (#10034)
chore(model): add metric for total number of conflicts (#10037)
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.
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.
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.
(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

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.

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
```

### 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.
Switch the database from LevelDB to SQLite, for greater stability and
simpler code.

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.
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.
### 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.

This allows users to easily disable nightly builds in their forks,
simply by disabling the
build-nightly action.
### Testing
I tested it in my fork, and it works.
### Purpose
Path autocompletion wasn't working when using `~` as a shortcut for the
home directory. The issue occurred because the tilde was expanded to
/home/user, which caused the suggestion to no longer match the input
(thus preventing the autocompletion from appearing in the suggestion
list).
To fix this, I replaced the custom `parentAndBase` function, which
handled path splitting in a more complex way, with `filepath.Split` from
the standard `path/filepath` package. This prevents tilde expansion
while keeping the expected behavior for path splitting.
### Testing
The issue has been tested manually on Linux.
### Screenshots
This is extracted from PR #9175. This deduplicates `SetPassword` calls
and makes `postAdjustGui` a single place where PR #9175 can add
another adjustment step for sanitizing changes to WebAuthn
credentials.
This also adds tests to validate that the refactored logic was not
broken.
These refactorizations were made in [PR #9175][1] to accommodate a few
new variants of authentication method and body content. On request from
reviewers, this PR extracts it as a smaller refactorization to review in
isolation.
### Purpose
This extracts a shared `httpRequest` base function from `httpGet` and
`httpPost`, which will be used in PR #9175 for new helper functions
`httpGetCsrf` (hiding all optional parameters except the CSRF token),
`httpPostCsrf` (same) and `httpPostCsrfAuth` (hiding basic auth
parameters). A `getSessionCookie` function is also extracted from
`hasSessionCookie` and will be used to test that concurrent WebAuthn
authentications result in separate sessions (indicated by different
session cookies).
### Purpose
On iOS, the FSEvents API for watching files (also used on macOS) is not
available, but `kqueue` is. This PR ensures `kqueue` support is built on
iOS instead of the FSEvents based watcher implementation.
Before this PR, you could already use the `kqueue` build option to force
its usage. Unfortunately `gomobile`, the tool that I use to build
Syncthing for iOS and macOS for Synctrain, does not support setting
different build flags for iOS and macOS (unless I build separately for
each, which is a bit of a hassle because XCode nonsense). I am assuming
there are good reasons to support FSEvents even though `kqueue` is also
available on macOS (but I'm not sure why?). I do know FSEvents has been
working fine for me on macOS so it seems best to use FSEvents on macOS
and kqueue on iOS.
Note that this also requires https://github.com/syncthing/notify/pull/4
to be merged in `synchting/notify` (until that is done, this PR will
fail to build on iOS due to `notify` still trying to link to `fsevents`
stuff when the `kqueue` build flag is not set).
### Testing
I compiled both `syncthing/notify` and syncthing with this PR applied,
and used that to successfully build the Synctrain iOS app, which after
this PR works fine and should follow up file changes a bit quicker.

The requirements for Windows code signing changed in 2023, so that newly
generated certificates can only be stored in hardware modules. Luckily,
I managed to snag a three year certificate before that so it hasn't
affected us so much. Now though, it does, because our cert is expiring
in March.
This changes the code signing process for Windows to use a cloud
service, Azure Trusted Signing. This appears to work equally well and
outsources the problem entirely, while also being cheaper than the
actual certificate was to begin with. 🤷
The signing entity will be Kastelo AB and not the Syncthing Foundation,
because the latter is almost impossible to get a certificate for as it's
not a normal corporate entity whose existence can be verified, etc. This
is also how it was prior to the latest certificate; it's not ideal, but
I think it's acceptable under the circumstances.
Currently, this just results in a very ambiguous `setting metadata: lookup
failed` while it could report what it's looking up and why it failed
(not found, etc).
Marshal() was called with the read lock held, and in turn called
Created() which also takes the read lock. This is fine by itself, but
there is a risk of deadlock if another call to lock the mutex happens
concurrently, as the lock call will block the inner rlock and the outer
rlock can never become unlocked.
It's an easy fix as marshalling is guaranteed to be called with a read
lock and does not need to call any methods that read lock themselves.
This was broken in the Protobuf refactor. The reason is that with the
previous library, generated types would have a JSON marshalling method
that would automatically return strings for enums. In the current
library you need to use the jsonpb marshaller for that, but these are
hand crafted structs so we can't do that. The easy solution is to just
use strings directly, since this is an API-only type anyway.
Commit dee920a840 was merged into
Weblate's repository, but later replaced on main by
2167ce9656. This led to a merge conflict,
which this commit fixes cleanly. After merging, we can unlock Weblate
again.
The GitHub checkout action does weird stuff with tags which breaks `git
describe`. This works around that so we get proper release builds on tag
pushes.
We must skip unix sockets, fifos, etc when scanning as these are not
filetypes we can handle. Currently we return a "bug" error, which
results in the walk being aborted and the rest of the tree being
essentially invisible to Syncthing. Instead, just ignore these files and
continue onwards.
This might well be #9859 as well but I can't confirm.
When creating an initial default config, we usually probe for a free
TCP port. But when a UNIX socket is specified via the `STGUIADDRESS=`
override or the `--gui-address=unix:///...` command line syntax, parsing
that option will fail during port probing.
The solution is to just skip the port probing when the address is
determined to specify something other than a TCP socket.
### Testing
Start with a fresh home directory each time.
1. Specify a UNIX socket for the GUI (works with this PR):
TMPHOME=$(mktemp -d); ./syncthing --home=$TMPHOME
--gui-address=unix://$TMPHOME/socket
2. Specify no GUI address (probes for a free port if default is taken,
as before):
TMPHOME=$(mktemp -d); ./syncthing --home=$TMPHOME
3. Specify a TCP GUI address (probes whether the given port is taken,
as before):
TMPHOME=$(mktemp -d); ./syncthing --home=$TMPHOME
--gui-address=127.0.0.1:8385
At a high level, this is what I've done and why:
- I'm moving the protobuf generation for the `protocol`, `discovery` and
`db` packages to the modern alternatives, and using `buf` to generate
because it's nice and simple.
- After trying various approaches on how to integrate the new types with
the existing code, I opted for splitting off our own data model types
from the on-the-wire generated types. This means we can have a
`FileInfo` type with nicer ergonomics and lots of methods, while the
protobuf generated type stays clean and close to the wire protocol. It
does mean copying between the two when required, which certainly adds a
small amount of inefficiency. If we want to walk this back in the future
and use the raw generated type throughout, that's possible, this however
makes the refactor smaller (!) as it doesn't change everything about the
type for everyone at the same time.
- I have simply removed in cold blood a significant number of old
database migrations. These depended on previous generations of generated
messages of various kinds and were annoying to support in the new
fashion. The oldest supported database version now is the one from
Syncthing 1.9.0 from Sep 7, 2020.
- I changed config structs to be regular manually defined structs.
For the sake of discussion, some things I tried that turned out not to
work...
### Embedding / wrapping
Embedding the protobuf generated structs in our existing types as a data
container and keeping our methods and stuff:
```
package protocol
type FileInfo struct {
*generated.FileInfo
}
```
This generates a lot of problems because the internal shape of the
generated struct is quite different (different names, different types,
more pointers), because initializing it doesn't work like you'd expect
(i.e., you end up with an embedded nil pointer and a panic), and because
the types of child types don't get wrapped. That is, even if we also
have a similar wrapper around a `Vector`, that's not the type you get
when accessing `someFileInfo.Version`, you get the `*generated.Vector`
that doesn't have methods, etc.
### Aliasing
```
package protocol
type FileInfo = generated.FileInfo
```
Doesn't help because you can't attach methods to it, plus all the above.
### Generating the types into the target package like we do now and
attaching methods
This fails because of the different shape of the generated type (as in
the embedding case above) plus the generated struct already has a bunch
of methods that we can't necessarily override properly (like `String()`
and a bunch of getters).
### Methods to functions
I considered just moving all the methods we attach to functions in a
specific package, so that for example
```
package protocol
func (f FileInfo) Equal(other FileInfo) bool
```
would become
```
package fileinfos
func Equal(a, b *generated.FileInfo) bool
```
and this would mostly work, but becomes quite verbose and cumbersome,
and somewhat limits discoverability (you can't see what methods are
available on the type in auto completions, etc). In the end I did this
in some cases, like in the database layer where a lot of things like
`func (fv *FileVersion) IsEmpty() bool` becomes `func fvIsEmpty(fv
*generated.FileVersion)` because they were anyway just internal methods.
Fixes#8247
Each section in the advanced settings dialog has similar code to insert
repeated input fields for each option. But only the first section (GUI
options) was adjusted in #9743 to avoid calling the `inputTypeFor()`
function repeatedly.
Apply the same caching to a locally scoped variable for each ng-repeat
entry by defining it in an ng-init directive.
I came accross this in another context and didn't investigate fully, but
literally ten lines above this code, in another method, we say that
filesets _must_ be created under the lock. It's either one or the other
and I'm taking the safer route here.

Encrypted-to-encrypted connections (i.e., ones where both sides set a
password) used to work but were broken in the 1.28.0 release. The
culprit is the 5342bec1b refactor which slightly changed how the request
was constructed, resulting in a bad block hash field.

### Purpose
When generating a new `config.xml` file with default options, the GUI
address is populated with a hard-coded default value of
`127.0.0.1:8384`, except for a random free port if that default one is
occupied. This is independent from the GUI configuration default address
defined in the protobuf description. More importantly, it ignores any
`STGUIADDRESS` override given via environment variable or command-line
option, thus probing for the default port instead of the one specified
via override.
The `ProbeFreePorts()` function now respects the override, by reading
the `GUIConfiguration.Address()` method instead of using hard-coded
defaults.
When not calling `ProbeFreePorts()`, the override should still be
persisted rather than the default address. This happens only when
generating a fresh default `config.xml`, never on an existing one.
This adds `allow_contributor: true` which allows approvals by
contributors to the PR (but still not the author themself, which is a
different thing). This allows things like pushing minor fixups while
also approving.
The `ignore_update_merges: true` option makes it so that someone is not
considered a "contributor" just because they push the merge button to
update the branch. In principle this is not needed given the above, but
I like it for clarity.
### Purpose
This closes#9400 by always expanding tildes when parent/subdir checks
are done.
### Testing
I tested this by creating folders with paths to parent or subdirectories
of the default folder that include a tilde in their path as shown in the
attached screenshots.
With this change, overlap will be detected regardless of wether or not
tildes are used in other folder paths.
### Screenshots

Newly created folder (parent directory in this case)

### Purpose
As discussed in #9686
Syncthing currently does not check folderstate on remote device before
pulling. If no devices have a valid folderstate (i.e all devices have
the folder paused) it will still attempt to pull. On large folders this
will cause a hanging "Syncing" status.
This checks whether at least one connected device has the file available
and has a valid folderstate.
### Testing
Tested locally on multiple devices.
We're new to Go (all our stuff is Python) so please bear with!
Interested if there may be a better place to slot this in.
Thanks,
Jon

Currently, the "Restart" and "Shutdown" buttons are displayed in the
middle of the Actions menu. On the other hand, the "Log Out" button is
displayed at the very bottom. However, in other cases, e.g. the menus in
operating systems like Windows or macOS, these kind of buttons are
usually grouped together.
Therefore, move the "Restart" and "Shutdown" buttons down, so that they
are listed together with the "Log Out" button. Also, change the order,
so that it goes from the least impactful ("Log Out") to the most
impactful ("Shutdown").

### Purpose
This fixes#9775. I also improved the comments as they were lacking.
My apologies for introducing this bug. In summary, the bug was
```
mode = mode ^ (ModeSymlink | ModeIrregular)
```
didn't correctly reset those bits. This correctly resets them:
```
mode = mode &^ ModeSymlink &^ ModeIrregular
```
Tested and working in Windows 11 version 10.0.22631.4317. I didn't test
in other versions, but I'm sure this is the only issue.
Currently we log on every single one of 10 retries deep in the upnp
stack. However we also return the failure as an error, which is bubbled
up a while until it's logged at debug level. Switch that around, such
that the repeat logging happens at debug level but the top-level happens
at info. There's some chance that this will newly log errors from
nat-pmp that were previously hidden in debug level - I hope those are
useful and not too numerous.
Also potentially this can even close#9324, my (very limited)
understanding of the reports/discussion there is that there's likely no
problem with syncthing beyond the excessive logging, it's some weird
router behaviour.
These CSS overrides address issues that are already present on wider
screens, so apply it there. Some experiments show we might even want to
up the limit more, but I am chicken and lazy, so I propose to use the
existing 470px media block.

As discussed in
https://github.com/syncthing/syncthing/pull/9175#discussion_r1730431703,
entries in advanced settings are unusable if they are comprised of a
list of objects. It just displays `[object Object], [object Object],
[object Object]`, e.g. for the devices a folder is shared with.
Filter out these config elements by detecting an array whose members are
not all strings or numbers, and setting them to `skip` type.
Fix some unnecessary repetition in calling `inputTypeFor()`, since it is
already cached in the `ng-init` directive.
### Purpose
Fixes#9776 by tweaking the text/background colours of disabled checkbox
panels when dark mode is enabled.
It was [noted on that
issue](https://github.com/syncthing/syncthing/issues/9776#issuecomment-2424828520)
that there's a bigger issue around the correctness of using the
`disabled` attribute on a `<div>` in the first place, but this PR does
not attempt to change that.
### Testing
I've hooked up the GUI files against a release build as suggested below.
### Screenshots
Using the dark theme, or the default theme with a system dark scheme:
Using the black theme:
These borrow the colours from dark theme text inputs and black theme
tabs for a consistent look (initially I tried the text colour of
disabled text inputs, but that produced some poor contrast).
Skipping these makes the sequence numbering inconcistent; we've received
a file and suppsedly added it to the database, but if you check the
sequence number afterwards it didn't increase, i.e., we trigger [this
failure
condition](47f48faed7/lib/model/indexhandler.go (L447-L459))
and, similarly, a future update will look like there was a hole in the
numbering.
I propose to at least temporarily remove this optimisation in order for
things to make more sense. Is there a reason to keep this beyond saving
some database operations?
This should prevent the panic that occurred in this test run:

### 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 44fef31780 (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.
This would have addressed a recent issue that arose when re-ordering our
"filesystem layers". Specifically moving the caseFilesystem to the
outermost layer. The previous cache included the filesystem, and as such
all the layers below. This isn't desirable (to put it mildly), as you
can create different variants of filesystems with different layers for
the same path and options. Concretely this did happen with the mtime
layer, which isn't always present. A test for the mtime related breakage
was added in #9687, and I intend to redo the caseFilesystem reordering
after this.

This is to add the generation of `compat.json` as a release artifact. It
describes the runtime requirements of the release in question. The next
step is to have the upgrade server use this information to filter
releases provided to clients. This is per the discussion in #9656

This changes the two remaining instances where we use insecure HTTPS to
use standard HTTPS certificate verification.
When we introduced these things, almost a decade ago, HTTPS certificates
were expensive and annoying to get, much of the web was still HTTP, and
many devices seemed to not have up-to-date CA bundles.
Nowadays _all_ of the web is HTTPS and I'm skeptical that any device can
work well without understanding LetsEncrypt certificates in particular.
Our current discovery servers use hardcoded certificates which has
several issues:
- Not great for security if it leaks as there is no way to rotate it
- Not great for infrastructure flexibility as we can't use many load
balancer or TLS termination services
- The certificate is a very oddball ECDSA-SHA384 type certificate which
has higher CPU cost than a more regular certificate, which has real
effects on our infrastructure
Using normal TLS certificates here improves these things.
I expect there will be some very few devices out there for which this
doesn't work. For the foreseeable future they can simply change the
config to use the old URLs and parameters -- it'll be years before we
can retire those entirely.
For the upgrade client this simply seems like better hygiene. While our
releases are signed anyway, protecting the metadata exchange is _better_
and, again, I doubt many clients will fail this today.
The test is quite odd and specific, but it does reproduce the issue that
caused #9677, so I'd propose to add it to have a simple regression test
for the basic scenario. Also the option to the fakefs might come handy
for other scenarios where you want to quickly test some behaviour on a
filesystem without nanosecond precision, without actually needing access
to one.
gui: Actually filter scope ID out of IPv6 address when using Remote GUI
(ref #8084)
The current code does not work, because it uses a string in the
replace() method instead of regex. Thus, change it to a proper regex.

The preference for languages in the Accept-Language header field
should not be deduced from the listed order, but from the passed
"quality values", according to the HTTP specification:
https://httpwg.org/specs/rfc9110.html#field.accept-language
This implements the parsing of q=values and ordering within the API
backend, to not complicate things further in the GUI code. Entries
with invalid (unparseable) quality values are discarded completely.
* gui: Fix API endpoint in comment.
gui: Fix incorrect UI language auto detection (fixes#9668)
Currently, the code only checks whether the detected language partially
matches one of the available languages. This means that if the detected
language is "fi" but among the available languages there is only "fil"
and no "fi", then it will match "fi" with "fil", even though the two are
completely different languages.
With this change, the matching is only done when there is a hyphen in
the language code, e.g. "en" will match with "en-US".

This adds a header with the operating system version, verbatim in
whatever format the operating system reports it, to the upgrade check.
The intention is that the upgrade server can use this information to
filter out (or maybe just mark) potentially unsupported upgrades.

### Purpose
Wrap access to Model for users that use the syncthing Go package. See
discussion:
https://github.com/syncthing/syncthing/pull/9619#pullrequestreview-2212484910
### Testing
It works with the iOS app. Other than that, there are no current users
of this API (to my knowledge) as Model was only exposed recently form
the iOS app.
### Purpose
This PR contains the set of changes needed to make Syncthing work on iOS
for [my iOS app for
Syncthing](https://github.com/pixelspark/sushitrain).
Most changes originate from [the Mobius Sync
fork](http://github.com/MobiusSync/syncthing/tree/ios). I have removed
the changes from their fork that are not strictly needed for my app
(i.e. their changes to the GUI and command line utilities, for instance)
and squashed it all in a single commit.
In summary, the changes are:
* Resolve non-absolute paths to the 'Documents' folder (basically the
only one an app can/should write user data to by default on iOS)
* Tweaking of build flags/conditions for iOS (i.e. determine which
basicfs_watch, ignoreresult variant to build for iOS)
* Disable upgrade mechanism on iOS
* Make `RequestGlobal` and `PullerProgress` public symbols
* Expose syncthing.app's Model instance (app.M)
* Add no-op stub for SetLowPriority on iOS
I would very much appreciate these changes to be (eventually) merged to
mainline syncthing, as this would allow my iOS app to track the mainline
source code directly and removes the need (for me at least) for
maintaining a separate fork. Perhaps the Mobius folks can also benefit
from this (although as noted this branch does not contain their changes
to e.g. the GUI).
### Testing
This branch has been tested with the iOS app and appears to work fine.
The full set of MobiusSync changes has been used before with success.
### Screenshots
n/a
### Documentation
There should be no visible changes for users due to this set of changes.

Tiny cleanup I noticed while trying to fix/test another issue
(https://github.com/syncthing/syncthing/pull/9600). I shortly tried to
figure out what it was used for in the past, but gave up without
results.
Previously we queried cache with backslashes, and stored entries with
slashes. As in no cache hits ever for non-toplevel files. I also
eventually remembered that cache is disabled by default, so this is a
bit pointless, but still right :P
### Purpose
Avoid the issue where the folder marker is deleted by overzealous
cleanup tools because it's just a useless, empty directory.
We create a small file containing a an admonishment to not delete the
directory, and some metadata that is just for human consumption at the
moment. (But it would parse as a valid yaml file if we wanted to read
this, at some point.)
This will only apply when _creating_ a folder marker, that is, existing
setups will not gain the file automatically. Obviously, when using a
custom folder marker none of this applies.
Also, slightly adjust the permission bits for the folder marker directory and file on Unixes, making sure the group & write bits are unset.
### Testing
I've created and deleted a few folders and it appears to behave as I
expect.
### Screenshots
```
jb@ok:~/somefolder % ls -la
total 0
drwxr-xr-x 3 jb staff 96 May 1 08:52 ./

# This directory is a Syncthing folder marker.
# Do not delete.

```
Currently the maximum delay is always derived automatically from the
initial delay. This is fine in most cases, but for some use cases (large
files that take a long time to write) we need to be able to set a longer
max delay than the computed value (e.g., 15s delay with 10min timeout).
This adds a small package `geoip` which knows how to download and manage
the Maxmind GeoLite2 database we use. This removes the need for various
scripts to download and manage the geoip database, something that today
happens on Docker startup for the relay pool server and using various
hand written hacks for the usage reporting server.
The database is downloaded when needed and then refreshed on a
best-effort basis weekly.

releases</a>.</em></p>
<blockquote>
<h2>v0.43.0</h2>
<h2><em>quic-go.net</em>: Launching a new Documentation Site</h2>
<p>With this release, we're launching a new documentation site for the
quic-go projects (quic-go itself, HTTP/3, webtransport-go, and soon,
masque-go): <a href="https://quic-go.net">quic-go.net</a>.</p>
<p>The documentation site aims to explain QUIC concepts and how they are
made accessible using quic-go's API. This site replaces the wiki, and
the ever-growing README files.</p>
<p>A lot of work has gone into the documentation already, but we're by
no means done yet. The entire source is public in <a
href="https://github.com/quic-go/docs/">https://github.com/quic-go/docs/</a>,
and we're happy about community contributions.</p>
<h2>HTTP Datagrams (RFC 9297)</h2>
<p>This release adds support for HTTP Datagrams (<a
href="https://datatracker.ietf.org/doc/html/rfc9297">RFC 9297</a>), both
on the client and on the server side (<a
href="https://redirect.github.com/quic-go/quic-go/issues/4452">#4452</a>).
HTTP Datagrams are used in WebTransport in CONNECT-UDP (<a
href="https://datatracker.ietf.org/doc/html/rfc9298">RFC 9298</a>),
among others.</p>
<p>The new API for HTTP Datagrams is described on the new documentation
page: <a href="https://quic-go.net/docs/http3/datagrams/">HTTP
Datagrams</a>. The integration of HTTP Datagram support necessitated a
comprehensive refactor of the HTTP/3 package, resulting in several
breaking API changes listed below.</p>

<li>http3: HTTP/3 client connections aren't removed if
<code>RoundTrip</code> errors due to a cancelled context (<a

<h2>Clarifications on the QUIC Stream State Machine</h2>
<h3>Calling CancelWrite after Close</h3>
<p>After a long and fruitful discussion (<a
href="https://redirect.github.com/quic-go/quic-go/issues/4404">#4404</a>),
we decided to clarify that calling <code>CancelWrite</code> after
<code>Close</code> on a <code>SendStream</code> (or a bidirectional
stream) should cause a state transition from the "Data Sent"
to the "Reset Sent" state, as described in <a
href="https://datatracker.ietf.org/doc/html/rfc9000#section-3.1">section
3.1 of RFC 9000</a>. This matches the current behavior of quic-go,
however, it didn't match the API documentation (fixed in <a
href="https://redirect.github.com/quic-go/quic-go/issues/4419">#4419</a>).</p>
<p>This means that stream data will not be delivered reliably if
<code>CancelWrite</code> is called, and that this applies even if
<code>Close</code> was called before.</p>
<h3>Garbage Collection of Streams</h3>
<p>This release also changes the way streams are garbage-collected (and
the peer is granted additional limit to open a new stream), once they're
not needed anymore, in a subtle way:</p>
<ul>
<li>for the send direction of streams: <a
href="https://redirect.github.com/quic-go/quic-go/issues/4445">#4445</a></li>

### Purpose
Adds a new metric `syncthing_connections_active` which equals to the
amount of active connections per device.
Fixes#9527
<!--
Describe the purpose of this change. If there is an existing issue that
is
resolved by this pull request, ensure that the commit subject is on the
form
`Some short description (fixes#1234)` where 1234 is the issue number.
-->
### Testing
I've manually tested it by running syncthing with these changes locally
and examining the returned metrics from `/metrics`.
I've done the following things:
- Connect & disconnect a device
- Increase & decrease the number of connections and verify that the
value of the metric matches with the amount displayed in the GUI.
### Documentation
https://github.com/syncthing/docs/blob/main/includes/metrics-list.rst
needs to be regenerated with
[find-metrics.go](https://github.com/syncthing/docs/blob/main/_script/find-metrics/find-metrics.go)

### Purpose
Firefox uses the last specified favicon link for bookmarks, but only if
it is available on initial page load.
Remove the second link and use ng-href to change the icon instead.
I'm not really familiar with AngularJS, feel free to offer suggestions
for improvements.
### Testing
Briefly tested on Firefox 124.0.2 and Chrome 123.0.6312.105.
### Purpose
Resend our indexes since we fixed that index-sending issue.
I made a new thing to only drop the non-local-device index IDs, i.e.,
those for other devices. This means we will see a mismatch and resend
all indexes, but they will not. This is somewhat cleaner as it avoids
resending everything twice when two devices are upgraded, and in any
case, we have no reason to force a resend of incoming indexes here.
### Testing
It happens on my computer...
The commit 7e4e65ebf5 added links to
devices listed in the Shared With list in the folder info. However, it
only added them to those that had no superscript next to them.
With this change, the links are added to all devices regardless of
whether they have the superscript next to their names or not. The commit
also simplifies the code by using anchors directly instead of wrapping
them in spans.

### Purpose
Bountysource no longer exists and the readme link 404s. This removes the
Bountysource link and corresponding readme section.
Perhaps the section should instead be replaced by other instructions for
voting on features.
This is an extract from PR #9175, which can be reviewed in isolation to
reduce the volume of changes to review all at once in #9175. There are
about to be several services and API handlers that read and set cookies
and session state, so this abstraction will prove helpful.
In particular a motivating cause for this is that with the current
architecture in PR #9175, in `api.go` the [`webauthnService` needs to
access the
session](https://github.com/syncthing/syncthing/pull/9175/files#diff-e2e14f22d818b8e635572ef0ee7718dee875c365e07225d760a6faae8be7772dR309-R310)
for authentication purposes but needs to be instantiated before the
`configMuxBuilder` for config purposes, because the WebAuthn additions
to config management need to perform WebAuthn registration ceremonies,
but currently the session management is embedded in the
`basicAuthAndSessionMiddleware` which is [instantiated much
later](https://github.com/syncthing/syncthing/pull/9175/files#diff-e2e14f22d818b8e635572ef0ee7718dee875c365e07225d760a6faae8be7772dL371-R380)
and only if authentication is enabled in `guiCfg`. This refactorization
extracts the session management out from `basicAuthAndSessionMiddleware`
so that `basicAuthAndSessionMiddleware` and `webauthnService` can both
use the same shared session management service to perform session
management logic.
### Testing
This is a refactorization intended to not change any externally
observable behaviour, so existing tests (e.g., `api_auth_test.go`)
should cover this where appropriate. I have manually verified that:
- Appending `+ "foo"` to the cookie name in `createSession` causes
`TestHtmlFormLogin/invalid_URL_returns_403_before_auth_and_404_after_auth`
and `TestHtmlFormLogin/UTF-8_auth_works` to fail
- Inverting the return value of `hasValidSession` cases a whole bunch of
tests in `TestHTTPLogin` and `TestHtmlFormLogin` to fail
- (Fixed) Changing the cookie to `MaxAge: 1000` in `destroySession` does
NOT cause any tests to fail!
- Added tests `TestHtmlFormLogin/Logout_removes_the_session_cookie`,
`TestHTTPLogin/*/Logout_removes_the_session_cookie`,
`TestHtmlFormLogin/Session_cookie_is_invalid_after_logout` and
`TestHTTPLogin/200_path#01/Session_cookie_is_invalid_after_logout` to
cover this.
- Manually verified that these tests pass both before and after the
changes in this PR, and that changing the cookie to `MaxAge: 1000` or
not calling `m.tokens.Delete(cookie.Value)` in `destroySession` makes
the respective pair of tests fail.
This re-implements the stalled enhancement from #8808. Thanks @Craeckie
for the idea and first implementation draft!
If a folder is shared to a device with encryption, add a lock icon in
front of the device name under "Shared With" in the folder details
panel. Be careful not to add whitespace caused by line wraps in HTML
source code, which would defeat the purpose of keeping the icon glued to
the name by a non-breaking space.
Apply the same lock icon for the list of folders shared with a device.
This change was split off from #9355 as an independent clean-up / fix.
See that PR for review discussion, testing, and screenshots.
Improve the wrapping of folder labels / device names by going back to
word-wrapping, but making sure other spans, such as the trailing comma,
do not get separated from the label span.
* Avoid adding whitespace caused by line wraps in HTML source code.
The different cases within the ng-switch block are separated by
newlines for readability, but that gets parsed as whitespace. For
wrapping purposes, this should not happen, because then there is no
way to keep other HTML parts glued to the name / label in each list
entry.
* Simplify redundant conditional comma code.
The separating comma after a device name or folder label (all but the
last) should always stick to it. Use the HTML comment trick to avoid
whitespace and therefore a wrapping opportunity caused by the code
formatting newline. Thus the conditional comma only needs to be
defined once, not in each ng-switch case.
* Wrap at word boundaries and only break up words if necessary.
Use the overflow-wrap: break-word; style instead of word-break:
break-all;. While the latter is suitable for longish paths, breaking
device names or folder labels arbitrarily within words is ugly.
This also makes the the <sup> numbers actually stay glued to their
respective neighboring words.
Include legacy CSS alias "word-wrap" in the class definition.
* Fix indentation (unrelated).
Adds a bool flag to `scanIfItemChanged()` to indicate when the scan was initiated from a delete function, and if so, tell `IsEquivalentOptional()` to ignore Xattrs and Ownership regardless of the global setting.
I tested this with my sledgehammer and it seems to pass.
Go is not cgroup aware and by default will set GOMAXPROCS to the number
of available threads, regardless of whether it is within the allocated
quota. This behaviour causes high amount of CPU throttling and degraded
application performance.
Add support for setting umask value in the Docker `entrypoint.sh`
script. This is useful when
not syncing permissions and working with groups, and needing umask
values like `002` instead of `022`.
The changes to go.mod in latest Go 1.21/1.22 are not fully understood by
older Go that might be pre-installed on builds, so make sure we always
have a modern one in place even for running small release scripts etc.
Somewhere along the way, the non-parallel test became parallel, and at
that point, timeouts occurred. Parallel is better, so increase the
timeout on the offending call a bit...
The new test has a flakiness factor on slow platforms, where the close
on the sending connection races with the last index message, potentially
messing up the count. This adds a wait to ensure that all sent messages
are received, or the test will eventually fail with a timeout.
Currently `IsTraced("xyz")` will return true for
any inclusion of "xyz" in string.
This change splits `STTRACE` using `','`, `' '` and `';'`
as delimiters. That makes facilities separation
more clear.
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...
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.

% 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

This pull request allows syncthing to request an IPv6
[pinhole](https://en.wikipedia.org/wiki/Firewall_pinhole), addressing
issue #7406. This helps users who prefer to use IPv6 for hosting their
services or are forced to do so because of
[CGNAT](https://en.wikipedia.org/wiki/Carrier-grade_NAT). Otherwise,
such users would have to configure their firewall manually to allow
syncthing traffic to pass through while IPv4 users can use UPnP to take
care of network configuration already.
### Testing
I have tested this in a virtual machine setup with miniupnpd running on
the virtualized router. It successfully added an IPv6 pinhole when used
with IPv6 only, an IPv4 port mapping when used with IPv4 only and both
when dual-stack (IPv4 and IPv6) is used.
Automated tests could be added for SOAP responses from the router but
automatically testing this with a real network is likely infeasible.
### Documentation
https://docs.syncthing.net/users/firewall.html could be updated to
mention the fact that UPnP now works with IPv6, although this change is
more "behind the scenes".

gui: Show folder/device status on small screens
On larger screens, folder and device status is shown in a textual form
directly next to folder and device titles. However, on small screens,
only icons are currently shown, which may be ambiguous to new users, who
cannot possibly know what a specific icon means (see [1]). Thus, on
small screens only, display a new entry in folder/device info that
contains the same textual information that is shown in the title on
larger screens.

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.
