This is shorter, skips two allocations, makes the function inlineable
and is safer, since the compiler now check whether
DeviceIDLength == sha256.Size.
Currently a random dev version has a version string like this:
v1.7.0-rc.1+23-gef3441bd6
That is, the tag name followed by a plus sign and the git describe
metadata (number of commits and hash) plus -dirty or -branchname in some
cases.
We introduced the plus sign in #473, where a dev version would
previously be called v0.9.0-42-gwhatever which is considered older than
v0.9.0 and hence caused a downgrade. The problem with the plus is that
per semver everything after the plus is ignored as build metadata, which
means we won't upgrade from v1.7.0-rc.1 to v1.7.0-rc.1+22-g946170f3f.
With this change the we instead either just add a dev suffix (if we're
already on a prerelease version) or we wind the patch version and add a
dev suffix.
v1.7.0-rc.1+23-gef3441bd6 => v1.7.0-rc.1.dev.23.gef3441bd6
v1.6.1+80-gef3441bd6 => v1.6.2-dev.80.gef3441bd6
This should preserve the ordering and keep versions semver-ish.
This changes the error handling in loading ignores slightly:
- There is a new ParseError type that is returned as the error
(somewhere in the chain) when the problem was not an I/O error loading
the file, but some issue with the contents.
- If the file was read successfully but not parsed successfully we still
return the lines read (in addition to nil patterns and a ParseError).
- In the API, if the error IsParseError then we return a successful
HTTP response with the lines and the actual error included in the JSON
object.
- In the GUI, as long as the HTTP call to load the ignores was
successful we can edit the ignores. If there was an error we show this
as a validation error on the dialog.
Also some cleanup on the Javascript side as it for some reason used
jQuery instead of Angular for this editor...
crypto/rand output is cryptographically secure by the Go library
documentation's promise. That, rather than strength (= passes randomness
tests) is the property that Syncthing needs).
This makes Go 1.15 test/vet happy, avoiding "conversion from untyped int
to string yields a string of one rune" warning where we do
string(KeyTypeWhatever) in namespaced.go.
It also clarifies and enforces the currently allowed range of these
numbers so I think it's fine.
This matches the convention of the stdlib and avoids ambiguity: when
customErr{} and &customErr{} both implement error, client code needs to
check for both.
Memory use should remain the same, since storing a non-pointer type in
an interface value still copies the value to the heap.
This extracts the extra tags from any `[foo]` stuff at the end of the
version and sends them to Sentry for indexing.
If I need to modify that regexp again I'll probably write a from scratch
tokenizer and parser for our version string instead...
This adds some env vars to the long version string as if they were build
tags. The purpose is to better understand what code was running or not
in the version output, usage reporting and crash reports. In order to
prevent possible privacy issues the actual value of the variable is not
reported, just the fact that it was set to something non-empty.
Example:
% ./bin/syncthing --version
syncthing v1.6.1+47-g1eb104f3-buildtags "Fermium Flea" (go1.14.3 darwin-amd64) jb@kvin.kastelo.net 2020-06-03 07:25:46 UTC [stnoupgrade, use_badger]
