This used to happen by itself as the connecting device always sent an
Index message and we triggered on that. Nowadays there's no guarantee
for that, but we anyway need to send out one event to let listeners know
the state of folders shared with the device.

This slightly changes the interface used for committing configuration
changes. The two parts are now:
- VerifyConfiguration, which runs synchronously and locked, and can
abort the config change. These callbacks shouldn't *do* anything
apart from looking at the config changes and saying yes or no. No
change from previously.
- CommitConfiguration, which runs asynchronously (one goroutine per
call) *after* replacing the config and releasing any locks. Returning
false from these methods sets the "requires restart" flag, which now
lives in the config.Wrapper.
This should be deadlock free as the CommitConfiguration calls can take
as long as they like and can wait for locks to be released when they
need to tweak things. I think this should be safe compared to before as
the CommitConfiguration calls were always made from a random background
goroutine (typically one from the HTTP server), so it was always
concurrent with everything else anyway.
Hence the CommitResponse type is gone, instead you get an error back on
verification failure only, and need to explicitly check
w.RequiresRestart() afterwards if you care.
As an added bonus this fixes a bug where we would reset the "requires
restart" indicator if a config that did not require restart was saved,
even if we already were in the requires-restart state.

This changes the BEP protocol to use protocol buffer serialization
instead of XDR, and therefore also the database format. The local
discovery protocol is also updated to be protocol buffer format.

If the listen address scheme is set to tcp4:// or tcp6://, it needs to be
made sure that the remote address matches this scheme before it is added to
the database.
This prevents invalid URIs like tcp4://<IPv6 address>:<port> or tcp6://<IPv4
address>:<port>.

This contains the following behavioral changes:
- Duplicate folder IDs is now fatal during startup
- Invalid folder flags in the ClusterConfig is fatal for the connection
(this will go away soon with the proto changes, as we won't have any
unknown flags any more then)
- Empty path is a folder error reported at runtime

Events API consumers rely on being able to detect that events were skipped
by the fact that the event ID has increased by more than 1. This is
documented, and is absolutely necessary when trying to maintain a local
model of Syncthing's state.
With the introduction of LocalChangeDetected, which is not exposed to the
Events API, this contract was broken.
This commit introduces separate concepts of a "Global ID" and a
"Subscription ID". The Global ID of an event is unique across all
subscriptions. The Subscription ID is local to a particular subscription,
and always increments by 1. They are both exposed over the Events API, but
the Subscription ID uses the key "id" for backwards compatibility, and
the "?since=xx" parameter refers to the Subscription ID (making the Global
ID for information only).

While attempting to fix#2782 I thought the problem was the
CheckFolderHealth method, so I cleaned it up. That turned out not to be
the case, but I think this is better anyhow.
It also moves the "create folder and marker if the folder was empty in
the index" code to StartFolder where I think it makes better sense.
This is covered by a number of existing tests.

The purpose of this operation is to separate the serving of GUI assets a
bit from the serving of the REST API. It's by no means complete. The end
goal is something like a combined server type that embeds a statics
server and an API server and wraps it in authentication and HTTPS and
stuff, plus possibly a named pipe server that only provides the API and
does not wrap in the same authentication etc.

As noted in the ticket I no longer agree that dev builds should not auto
upgrade. The main reason is that we give dev builds to users to test
specific fixes, and noone is happier by them being inadvertently stuck
on that version when a newer version including the fix is released.
For developers, it's first of all probably unlikely that development is
happening on a build that's older than release, and secondly STNOUPGRADE
can be set in the environment once and for all if it an issue.

With the previous setup, browsers were free to use a local cache for any
length of time they pleased: we didn't set an 'Expires' header (or max-age
directive), and Cache-Control just said "you're free to cache this".
Therefore be more explicit: we don't mind if browsers cache things, but they
MUST revalidate everything on every request.

The intention for this package is to provide a combination of the
security of crypto/rand and the convenience of math/rand. It should be
the first choice of random data unless ultimate performance is required
and the usage is provably irrelevant from a security standpoint.

We need to set these properties *before* Angular starts making requests,
and doing that from the response to a request is too late. The obvious
choice (to me) would be to use the angular $cookies service, but that
service isn't available until after initialization so we can't use it.
Instead, add a special file that is loaded by index.html and includes
the info we need before the JS app even starts running.

Without this the summary service doesn't know to recalculate completion
percentage for remote devices when DownloadProgress messages come in.
That means that completion percentage isn't updated in the GUI while
transfers of large files are ongoing. With this change, it updates
correctly.

I think this better reflects what it means. Also tweaks the verbose
format to be more like our other things and lightly refactors the code

Because json.NewDecoder(r).Decode(&v) doesn't necessarily consume all
data on the reader, that means an HTTP connection can't be reused. We
don't do a lot of HTTP traffic where we read JSON responses, but the
discovery is one such place. The other two are for POSTs from the GUI,
where it's not exactly critical but still nice if the connection still
can be keep-alive'd after the request as well.
Also ensure that we call req.Body.Close() for clarity, even though this
should by all accounts not really be necessary.

1. Removes separate relay lists and relay clients/services, just makes it a listen address
2. Easier plugging-in of other transports
3. Allows "hot" disabling and enabling NAT services
4. Allows "hot" listen address changes
5. Changes listen address list with a preferable "default" value just like for discovery
6. Debounces global discovery announcements as external addresses change (which it might alot upon starting)
7. Stops this whole "pick other peers relay by latency". This information is no longer available,
but I don't think it matters as most of the time other peer only has one relay.
8. Rename ListenAddress to ListenAddresses, as well as in javascript land.
9. Stop serializing deprecated values to JSON

A potential practical use is to encode a short version of the hostname
at the beginning of the device ID.
For example:
jb@syno:~/s/g/s/s/c/stvanity $ stvanity abc
Want 15 bits for prefix "ABC", about 3.3e+04 certs to test (statistically speaking)
Found ABCFPWS-JKDIFV3-E5IUAQW-DK53WVR-HY7XWBS-56H33GR-CJQI67Q-VGXRMAW
Saved to cert.pem, key.pem
jb@syno:~/s/g/s/s/c/stvanity $ stvanity $(hostname)
Want 20 bits for prefix "SYNO", about 1e+06 certs to test (statistically speaking)
Trying 554 certs/s, tested 8307 so far in 15s, expect ~32m total time to complete
Trying 543 certs/s, tested 16277 so far in 30s, expect ~32m total time to complete
...
The rest is just a matter of patience.
jb@syno:~/s/g/s/s/c/stvanity $ stvanity syncthing
Want 50 bits for prefix "SYNCTHI-NG", about 1.1e+15 certs to test (statistically speaking)

When run without parameters, attempts to listen for local discovery
announcements just like Syncthing, and prints them.
With -send, it also sends fake discovery packets. This can be used on
two or more computers simultaneously to verify that they can see each
other.
GitHub-Pull-Request: https://github.com/syncthing/syncthing/pull/2985
This fixes both a race condition where we could assign s.stop from one
goroutine and then read it from another without locking, and handles the
fact that listener may be nil at shutdown if we've had a bad
CommitConfiguration call in the meantime.
This updates the modified time of the config file before archiving it
during an update so that the clean up routine doesn't delete it if it's
too old, preventing the user from being able to rollback after an
upgrade.
This gets rid of redundant checks and centralizes the logic of loading
the config files so that we don't have to keep doing the same thing in
multiple places.
I'm not really sure under what circumstances MkdirAll returns a nil
error but a subsequent stat fails, but apparently it can happen and we
need to handle it. The "mode >= 0" was a no-op, and we never call
ensureDir anyway without the intention of ensuring the mode, so removed
that.
This avoids the double negative of having noConsole = false to represent
not hiding the console. It is also consistent with the action performed
by osutils.
This takes advantage of the newly created parseCommandLineOptions()
function and makes it work so that it now returns a nice struct of
options rather than relying on global variables.
There are a few global variables left, but they will take a bit more
refactoring in order to be removed, so it'll happen in later commits.
ensureDir() did not handle one last error case and there was some logic
in the main() function that belonged to ensureDir() as well. It was also
creating a directory with a hardcoded 0700 mode, regardless of what mode
was passed to it.
This refactors it a little to fix the broken behavior, avoid redundant
checks by taking advantage of the behavior of MkdirAll, and move the
extra logic from main() into ensureDir().
The main() function is growing too big (142 lines as of the date of this
commit), so this attempts to extract some functionality out of there and
into their own functions to make it easier to reason about them and keep
functions short and concise.
--browser-only assumes syncthing is already running and will open the
user's browser in the URL:port currently used in the configuration if
the GUI is enabled.
Every time a JSON object is returned in an HTTP response, the
appropriate header needs to be set and the object itself needs to be
encoded. Doing this in every function is repetitive and error prone
(getDBFile and postDBScan, for instance, never set any headers).
This adds a helper function to centralize the appropriate JSON response
handling.
With this change, the behavior is as follows:
- SIGTERM / SIGINT: Exit cleanly (exit code 0)
- SIGHUP: Restart
This is the case both when hitting the monitor process or the inner
process, or if running with NORESTART (but then we won't restart,
obviously, just exit with code exitRestarting).
It enables "pkill -HUP syncthing" to do the right thing to restart all
Syncthings on package upgrade, for example.
Also fixes what I think migh thave been a bug where we did not use the
proxy for usage reports. And removes the BuildEnv field that we don't
need any more.
