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.
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.
### 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)

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
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.

(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 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 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.
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.

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.

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...
