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.
### 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.

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 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.
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.
This adds the ability to have multiple concurrent connections to a single device. This is primarily useful when the network has multiple physical links for aggregated bandwidth. A single connection will never see a higher rate than a single link can give, but multiple connections are load-balanced over multiple links.
It is also incidentally useful for older multi-core CPUs, where bandwidth could be limited by the TLS performance of a single CPU core -- using multiple connections achieves concurrency in the required crypto calculations...

This adds a cache to the expensive key generation operations. It's fixes
size LRU/MRU stuff to keep memory usage bounded under absurd conditions.
Also closes#8600.
This replaces old style errors.Wrap with modern fmt.Errorf and removes
the (direct) dependency on github.com/pkg/errors. A couple of cases are
adjusted by hand as previously errors.Wrap(nil, ...) would return nil,
which is not what fmt.Errorf does.
* lib/locations: Fix enum values camelCase.
* lib/locations: Remove unused FailuresFile.
* cmd/syncthing: Turn around role of locations storage.
Previously the locations package was used to provide default paths,
possibly with an overridden home directory. Extra paths supplied on
the command line were handled and passed around in the options object.
To make the changed paths available to any other interested package,
override the location setting from the option if supplied, instead of
vice versa when not supplied. Adapt code using this to read from the
locations package instead of passing through the options object.
* lib/locations: Refactor showPaths to locations package.
Generate a reusable string in locations.PrettyPrintPaths().
Enumerating all possible locations in different packages is error
prone, so add a new public function to generate the listing as a
string in the locations package. Adapt cmd/syncthing --paths to use
that instead of its own console output.
* lib/locations: Include CSRF token in pretty printed paths.
* lib/api: New endpoint /rest/system/paths.
The paths should be available for troubleshooting from a running
instance. Using the --paths CLI option is not easy in some
environments, so expose the locations mapping to a JSON endpoint.
Add utility function ListExpandedPaths() that also filters out any
entries which still contain variable placeholders.
* gui: List runtime paths in separate log viewer tab.
* Wrap paths.
* lib/syncthing: Utilize locations.Get() instead of passing an arg.
* Include base directories, move label to table caption.
* gui: Switch to hard-coded paths instead of iterating over all.
* gui: Break aboutModalView into tabs.
Use tabs to separate authors from included third-party software.
* gui: Move paths from log viewer to about modal.
* lib/locations: Adjust pretty print output order to match GUI.
* gui, authors: Remove additional bot names and fix indent.
The indentation changed because of the tabbed about dialog, fix the
authors script to respect that.
Skip Syncthing*Automation in authors list as well.
* Update AUTHORS list to remove bot names.
* Revert AUTHORS email order change.
* Do not emphasize DB and log file locations.
* Review line wrapping.
* review part 1: strings.Builder, naming
* Rename and extend locations.Set() with error handling.
Remodel the Override() function along the existing SetBaseDir() and
rename it to simply Set(). Make sure to use absolute paths when given
log file or GUI assets override options. Add proper error reporting
if that goes wrong.
* Remove obsolete comment about empty logfile option.
* Don't filter out unexpanded baseDir placeholders, only ${timestamp}.
* Restore behavior regarding special "-" logfile argument.
If the option is given, but with empty value, assume the no log
file (same as "-"). Don't try to convert the special value to an
absolute path though and document this fact in a comment for the Set()
function.
* Use template to check for location key validity.
* Don't filter out timestamp placeholders.
* lib/api: Remove paths from /rest/system/status.
* lib/ur: Properly initialize map in failure data (fixes#8479)

* cmd/syncthing: Remove unnecessary function arguments.
The openGUI() function does not need a device ID to work, and there is
only one caller anyway which uses EmptyDeviceID.
The loadOrDefaultConfig() function is always called with the same
dummy values.
* cmd/syncthing: Avoid misleading info messages from monitor process.
In order to check whether panic reporting is enabled, the monitor
process utilizes the loadOrDefaultConfig() function. In case there is
no config file yet, info messages may be logged during creation if the
config Wrapper, which is discarded immediately after.
Stop using the DefaultConfig() utility function from lib/syncthing and
directly generate a minimal config instead to avoid these.
Add comments to loadOrDefaultConfig() explaining its limited purpose.
* cmd/syncthing/generate: Always write updated config file.
Previously, an existing config file was left untouched unless either
of the --gui-user or --gui-password options was given. Remove that
condition and simplify the checking code.
* lib/config: Factor out ProbeFreePorts().
* cmd/syncthing: Add option --skip-port-probing.
Applies to both the "generate" and "serve" subcommands, as well as the
deprecated --generate option, just as the --no-default-folder flag.
Accept a subcommand as an alternative to the --generate option. It
accepts a custom config directory through either the --home or
--config options, using the default location if neither is given.
Add the options --gui-user and --gui-password to "generate", but not
the "serve --generate" option form. If either is given, an existing
config will not abort the command, but rather load, modify and save it
with the new credentials. The password can be read from standard
input by passing only a single dash as argument.
Config modification is skipped if the value matches what's already in
the config.
* cmd/syncthing: Utilize lib/locations package in generate().
Instead of manually joining paths with "magic" file names, get them
from the centralized locations helper lib.
* cmd/syncthing: Simplify logging for --generate option.
Visible change: No more timestamp prefixes.
LoadOrGenerateCertificate() takes two file path arguments, but then
uses the locations package to determine the actual path. Fix that
with a minimally invasive change, by using the arguments instead.
Factor out GenerateCertificate().
The only caller of this function is cmd/syncthing, which passes the
same values, so this is technically a no-op.
* lib/tlsutil: Make storing generated certificate optional. Avoid
temporary cert and key files in tests, keep cert in memory.
Consistently use double dashes and fix typos -conf, -data-dir and
-verify.
Applies also to tests running the syncthing binary for consistency.
* Fix mismatched option name --conf in cli subcommand.
According to the source code comments, the cli option flags should
mirror those from the serve subcommand where applicable. That one is
actually called --config though.
* cli: Fix help text option placeholders.
The urfave/cli package uses the Value field of StringFlag to provide a
default value, not to name the placeholder. That is instead done with
backticks around some part of the Usage field.
* cli: Add missing --data flag in subcommand help text.
The urfave/cli based option parsing uses a fake flags collection to
generate help texts matching the used global options. But the --data
option was omitted from it, although it is definitely required when
using --config as well. Note that it cannot just be ignored, as some
debug stuff actually uses the DB:
syncthing cli --data=/bar --config=/foo debug index dump
This makes us use TLS 1.3+ on sync connections by default. A new option
`insecureAllowOldTLSVersions` exists to allow communication with TLS
1.2-only clients (roughly Syncthing 1.2.2 and older). Even with that
option set you get a slightly simplified setup, with the cipher suite
order fixed instead of auto detected.
This makes the GC runner a service that will stop fairly quickly when
told to.
As a bonus, STTRACE=app will print the service tree on the way out,
including any errors they've flagged.
