This PR does two things, because one lead to the other:
- Move the leveldb specific stuff into a small "backend" package that
defines a backend interface and the leveldb implementation. This allows,
potentially, in the future, switching the db implementation so another
KV store should we wish to do so.
- Add proper error handling all along the way. The db and backend
packages are now errcheck clean. However, I drew the line at modifying
the FileSet API in order to keep this manageable and not continue
refactoring all of the rest of Syncthing. As such, the FileSet methods
still panic on database errors, except for the "database is closed"
error which is instead handled by silently returning as quickly as
possible, with the assumption that we're anyway "on the way out".
Since we've taken upon ourselves to create a log file by default on
Windows, this adds proper management of that log file. There are two new
options:
-log-max-old-files="3" Number of old files to keep (zero to keep only current).
-log-max-size="10485760" Maximum size of any file (zero to disable log rotation).
The default values result in four files (syncthing.log, synchting.0.log,
..., syncthing.3.log) each up to 10 MiB in size. To not use log rotation
at all, the user can say --log-max-size=0.
* lib/versioner: Reduce surface area
This is a refactor while I was anyway rooting around in the versioner.
Instead of exporting every possible implementation and the factory and
letting the caller do whatever, this now encapsulates all that and
exposes a New() that takes a config.VersioningConfiguration.
Given that and that we don't know (from the outside) how a versioner
works or what state it keeps, we now just construct it once per folder
and keep it around. Previously it was recreated for each restore
request.

- The 'help-box' with nearby devices will appear only when there are
any nearby devices
- IDs of nearby devices will look like links (i.e. underlined when
hovered over)
We incorrectly gave a too small buffer to lz4.Compress, causing it to
allocate in some cases (when the data actually becomes larger when
compressed). This then panicked when passed to the buffer pool.
This ensures a buffer that is large enough, and adds tripwires closer to
the source in case this ever pops up again. There is a test that
exercises the issue.
* gui, lib/api: Adds support for prefers-color-scheme on default theme (fixes#6115)
- Renames current default theme into a new "light" theme
- Modifies assets serving to allow getting assets from different themes
* lib/api: Serve assets from arbitrary theme when path starts with "theme-assets"
* lib/api: Moves constant out of function
* Loads light theme in browsers without support for prefers-color-scheme
* gui: Disables dark theme when printing
* Prevents repeated injection and adds support for older browsers
The CSS is always loaded if there is no support for `matchMedia`.
This is apparently an old benchmarking tool. I'd forgotten about it.
Since 67b8ef1f3e the build script tries to
build all binaries explicitly by default, and this fails on Windows as
this tool doesn't build on Windows.
Kill it with fire.
* Fix bufferpool puts (ref #4976)
There was a logic error in Put() which made us put all large blocks into
segment zero, where we subsequently did not look for them.
I also added a lowest threshold, as we otherwise allocate a 128KiB
buffer when we need 24 bytes for a header and such.
