The math/rand package contains lots of convenient functions, for example
to get an integer in a specified range without running into issues
caused by just truncating a number from a different distribution and so
on. But it's insecure, and we use if for things that benefit from being
more secure like session IDs, CSRF tokens and API keys.
This implements a math/rand.Source that reads from crypto/rand.Reader,
this bridging the gap between them. It also updates our RandomString to
use the new source, thus giving us secure session IDs and CSRF tokens.
Some future work remains:
- Fix API keys by making the generation in the UI use this code as well
- Refactor out these things into an actual random package, and audit
our use of randomness everywhere
I'll leave both of those for the future in order to not muddy the waters
on this diff...

Switch to my forked version which contains a fix for this issue. I'll
track upstream in the future if things update there, and attempt to
contribute back fixes...

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
to not have the boolean and include the folder in the event.

This was fixed upstream due to our ticket, so we no longer need the
manual handling of commas. Keep the tests and better debug output around
though.

The old usage pattern was to create a Walker with a bunch of attributes,
then call Walk() on it and nothing else. This extracts the attributes
into a Config struct and exposes a Walk(cfg Config) method instead, as
there was no reason to expose the state-holding walker type.
Also creates a few no-op implementations of the necessary interfaces
so that we can skip nil checks and simiplify things here and there.
Definitely look at this diff without whitespace.

Just an optimization. Required exposing the priority from the factory,
so made that an interface with an extra method instead of just a func
type.

This fixes the deadlock by reducing where we hold the various locks. To
start with it splits up the existing "mut" into a "listenersMut" and a
"curConMut" as these are the two things being protected and I can see no
relation between them that requires a shared lock. It also moves all
model calls outside of the lock, as I see no reason to hold the lock
while calling the model (and it's risky, as proven).

When doing prefix scans in the database, "foo" should not be considered
a prefix of "foo2". Instead, it should match "foo" exactly and also
strings with the prefix "foo/". This is more restrictive than what the
standard leveldb prefix scan does so we add some code to enforce it.
Also exposes the initialScanCompleted on the rwfolder for testing, and
change it to be a channel (so we can wait for it from another
goroutine). Otherwise we can't be sure when the initial scan has
completed, and we need to wait for that or it might pick up changes
we're doing at an unexpected time.

The VersioningConfig change is because it defaults to nil but gets
deserialized to map[string]string{}. Now prepare() enforces a single
representation of the empty map.

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.

New signature is the HMAC of archive name (which includes the release
version and architecture) plus the contents of the binary. This is
expected in a new file "release.sig" which may be present in a
subdirectory. The new release tools put this in [.]metadata/release.sig.

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

This happens automatically in the background anyway, and it can take a
long time on low powered devices at an inconvenient time. We just want
to get up and running as quickly as possible.
GitHub-Pull-Request: https://github.com/syncthing/syncthing/pull/3000
Previously the code failed in that it would return top-level plus a sub,
i.e. ["", "foo"], and it would consider "usr/lib" a prefix of
"usr/libexec" which it is not.
More prominent positions are given to authors with more commits, in
steps of magnitude. Authors with 100-999 commits are listed before
authors with 10-99 commits. Yes, this puts me at the head of the list
and is a slight ego trip, but I still think it's the right thing to do.
Fixes#2151.
Since Walk.walkAndHashFiles ignores .stfolder and .stignore, they will
never be found by fs.Get(protocol.LocalDeviceID, sub) in
Model.internalScanFolder. As a result, when asked to scan those subs
we end up scanning the whole folder.
This reverts the change introduced in 9b9fe0d Reduce scanning effort.
That commit caused us to automatically ignore the basename of the
specified subs and instead scan closest known root folder. For
example, in a folder that looks like:
Sync/
├── 00
│ ├── one
│ ├── three
│ └── two
├── 01
│ ├── one
│ ├── three
│ └── two
├── 02
│ ├── one
│ ├── three
│ └── two
└── one
calling '/rest/db/scan?folder=default&sub=01' called filepath.Walk on
the whole Sync/ folder instead of just the desired subfolder. This
contradicts the scan behavior promised by the documentation.
This is related to #2151.
We only need to protect the integrity of the "finders" and "caches"
slices, and for that we only need an RLock except while actually
appending to them. The actual finders and caches are concurrency safe on
their own.
After the first media break (under 1200px), the footer is too long to
fit in a single line, taking up too much space in small screen devices.
This makes it so that it will stop being fixed at the bottom, freeing up
valuable screen real estate.
Safari has its own standard for handling icons for pinned tabs,
which requires a black-and-white .svg and a special tag.
Without using this, pinning a tab to localhost will show just
a blank square, instead of a pre-generated letter.
Checks the existing blocks that can be reused when downloading a file so
that it only requires the space corresponding to the missing blocks.
This will prevent syncthing from claiming the folder doesn't have enough
space when resuming download of large files after they have been
partially downloaded.
This will open the "edit device" dialogue after accepting a new device
connection. This will allow the user to specify the name of the device
or leave it blank in case they want to accept whatever the device
advertises once it connects.
When upgrade info is not available and the "Automatic Upgrades" options
is hidden, then "Global Discovery Server" wraps around and gets
misaligned. This fixes all that.
Previously, when unmarshing the SOAP error code data we would overwrite
the original err, typically with null since the parsing of the error
code information succeeds. If we don't have a upnp 725 error, we would fall
back to returning null or no error. This broke our upnp error handling
logic for AddPortMappings as it would think it succeeds if it gets a 718
permission error.
