* 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`.
* 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.

This adds a certificate lifetime parameter to our certificate generation
and hard codes it to twenty years in some uninteresting places. In the
main binary there are a couple of constants but it results in twenty
years for the device certificate and 820 days for the HTTPS one. 820 is
less than the 825 maximum Apple allows nowadays.
This also means we must be prepared for certificates to expire, so I add
some handling for that and generate a new certificate when needed. For
self signed certificates we regenerate a month ahead of time. For other
certificates we leave well enough alone.
The relay and discosrv didn't use the new lib/build package, now they
do. Conversely the lib/build package wasn't aware there might be other
users and hard coded the program name - now it's set by the build
script
This adds a field `guiAddressUsed` to the system status response, that
holds the current listening address actually in use. This may be
different from the one stored in the config because it may have been
overridden by environment or command line flag.
The GUI now checks this field to see if we are listening on localhost.
If we are not, the authentication required warning is displayed,
regardless of the *configured* listening address.
This is an experiment in testing, based on the advise to always call
t.Parallel() at the start of every test. Doing so makes tests run in
parallel, which is usually faster, but also exposes package level state
and potential race conditions better.
To support this I had to redesign the CSRF manager to not be package
global, which was indeed an improvement. And tests run five times faster
now.
This splits large writes into smaller ones when using a rate limit,
making them into a legitimate trickle rather than large bursts with a
long time in between.
This is the result of:
- Changing build.go to take the protobuf version from the modules
instead of hardcoded
- `go get github.com/gogo/protobuf@v1.3.0` to upgrade
- `go run build.go proto` to regenerate our code
Assume a folder error was set due to bad ignores on the latest scan.
Previously, doing a manual rescan would result in:
1. Clearing the folder error, which schedules (immediately) an fs
watcher restart
2. Attempting to load the ignores, which fails, so we set a folder
error and bail.
3. Now the fs watcher restarts, as scheduled, so we trigger a scan.
Goto 1.
This change fixes this by not clearing the error until the error is
actually cleared, that is, if both the health check and ignore loading
succeeds.
This introduces a better set of defaults for large databases. I've
experimentally determined that it results in much better throughput in a
couple of scenarios with large databases, but I can't give any
guarantees the values are always optimal. They're probably no worse than
the defaults though.
NATSymmetricUDPFirewall actually is not NAT at all, but means the machine has a global IP address and an UDP firewall in front (RFC calls it Symmetric UDP Firewall). This is punchable fine, both theoretically and also practically in testing.
* lib/model: Don't panic on failed chmod-back on directory (fixes#5836)
This makes the "in writable dir"-wrapper log chmod-back errors instead
of panicking. To do that we need a logger so the function moved into the
model package which is also the only place it's used. The tests came
along.
(The test also exercised osutil.RenameOrCopy like some sort of
piggybacking. I removed that.)
This adds a set of magical environment variables that can be used to
tweak the database parameters. It's totally undocumented and not
intended to be a long term or supported thing.
It's ugly, but there is a backstory. I have a couple of large
installations where the database options are inefficient or otherwise
suboptimal (24/7 compaction going on and stuff like that). I don't
*know* the correct database parameters, nor yet the formula or method to
derive them by, so this requires experimentation. Experimentation needs
to happen partly in production, and rolling out new builds for every
tweak isn't practical. This provides override points for all reasonable
values, while not changing anything by default.
Ideally, at the end of such experimentation, we'll know which values are
relevant to change and in what manner, and can provide a more user
friendly knob to do so - or do it automatically based on the database
size.

Per the sync/atomic bug note:
> On ARM, x86-32, and 32-bit MIPS, it is the caller's
> responsibility to arrange for 64-bit alignment of 64-bit words
> accessed atomically. The first word in a variable or in an

All atomic accesses of 64-bit variables in syncthing code base are
currently ok (i.e they are all 64-bit aligned).
Generally, the bug is triggered because of incorrect alignement
of struct fields. Free variables (declared in a function) are
guaranteed to be 64-bit aligned by the Go compiler.
To ensure the code remains correct upon further addition/removal
of fields, which would change the currently correct alignment, I
added the following comment where required:
// atomic, must remain 64-bit aligned

* lib/versioner: Add placeholder to provide the absolute file path to external commands
This commit adds support for a new placeholder, %FILE_PATH_FULL%, to the
command of the external versioner. The placeholder will be replaced by
the absolute path of the file that should be deleted.
* Revert "lib/versioner: Add placeholder to provide the absolute file path to external commands"
This reverts commit fb48962b947358e90a76e87a7794adb6057de476.
* lib/versioner: Replace all placeholders in external command (fixes#5849)
Before this commit, only these placeholders were replaced that span a
whole word, for example "%FOLDER_PATH%". Words that consisted of more
than one placeholder or additional characters, for example
"%FOLDER_PATH%/%FILE_PATH%", were left untouched.
* fixup! lib/versioner: Replace all placeholders in external command (fixes#5849)
