Jakob Borg 7c8418f493 build: Support builds outside of GOPATH
This adds support for building with the source placed anywhere and no
GOPATH set. The build script handles this by creating a temporary GOPATH
in the system temp dir (or another specified location) and mirroring the
source there before building. The resulting binaries etc still end up in
the same place as usual, meaning at least the "build", "install", "tar",
"zip", "deb", "snap", "test", "vet", "lint", "metalint" and "clean"
commands work without a GOPATH. To this end these commands internally
use fully qualified package paths like
"github.com/syncthing/syncthing/cmd/..." instead of "./cmd/..." like
before.

There is a new command "gopath" that prepares and echoes the directory
of the temporary GOPATH. This can be used to run other non-build go
commands:

export GOPATH=$(go run build.go gopath)  // GOPATH is now set
go test -v -race github.com/syncthing/syncthing/cmd/...

There is a new option "-no-build-gopath" that prevents the
check-and-copy step, instead assuming the temporary GOPATH is already
created and up to date. This is a performance optimization for build
servers running multiple builds commands in sequence:

go run build.go gopath // creates a temporary GOPATH
go run build.go -no-build-gopath -goos=... tar // reuses GOPATH
go run build.go -no-build-gopath -goos=... tar // reuses GOPATH

The temporary GOPATH is placed in the system temporary directory
(os.TempDir()) unless overridden by the STTMPDIR variable. It is named
after the hash of the current directory where build.go is run. The
reason for this is that the name should be unique to a source checkout
without risk for conflict, but still persistent between runs of
build.go.

Goals

Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers. We strive to fulfill the goals below. The goals are listed in order of importance, the most important one being the first. This is the summary version of the goal list - for more commentary, see the full Goals document.

Syncthing should be:

  1. Safe From Data Loss

    Protecting the user's data is paramount. We take every reasonable precaution to avoid corrupting the user's files.

  2. Secure Against Attackers

    Again, protecting the user's data is paramount. Regardless of our other goals we must never allow the user's data to be susceptible to eavesdropping or modification by unauthorized parties.

  3. Easy to Use

    Syncthing should be approachable, understandable and inclusive.

  4. Automatic

    User interaction should be required only when absolutely necessary.

  5. Universally Available

    Syncthing should run on every common computer. We are mindful that the latest technology is not always available to any given individual.

  6. For Individuals

    Syncthing is primarily about empowering the individual user with safe, secure and easy to use file synchronization.

  7. Everything Else

    There are many things we care about that don't make it on to the list. It is fine to optimize for these values, as long as they are not in conflict with the stated goals above.

Getting Started

Take a look at the getting started guide.

There are a few examples for keeping Syncthing running in the background on your system in the etc directory. There are also several GUI implementations for Windows, Mac and Linux.

Vote on features/bugs

We'd like to encourage you to vote on issues that matter to you. This helps the team understand what are the biggest pain points for our users, and could potentially influence what is being worked on next.

Getting in Touch

The first and best point of contact is the Forum. There is also an IRC channel, #syncthing on freenode (with a web client), for talking directly to developers and users. If you've found something that is clearly a bug, feel free to report it in the GitHub issue tracker.

Building

Building Syncthing from source is easy, and there's a guide that describes it for both Unix and Windows systems.

Signed Releases

As of v0.10.15 and onwards release binaries are GPG signed with the key D26E6ED000654A3E, available from https://syncthing.net/security.html and most key servers.

There is also a built in automatic upgrade mechanism (disabled in some distribution channels) which uses a compiled in ECDSA signature. Mac OS X binaries are also properly code signed.
