* The source code for the release
* The exact version of the official `Go compiler <https://golang.org>`__ used to produce the binaries (running ``restic version`` will print this)
* The architecture and operating system the Go compiler runs on (Linux, ``amd64``)
* The build tags (for official binaries, it's the tag ``selfupdate``)
* The path where the source code is extracted to (``/restic``)
* The path to the Go compiler (``/usr/local/go``)
* The build tags (for official binaries, it's the tag ``selfupdate``)
* The environment variables (mostly ``$GOOS``, ``$GOARCH``, ``$CGO_ENABLED``)
* The path to the Go workspace (``GOPATH=/home/build/go``)
* Other environment variables (mostly ``$GOOS``, ``$GOARCH``, ``$CGO_ENABLED``)
In addition, The compressed ZIP files for Windows depends on the modification
timestamp and filename of the binary contained in it. In order to reproduce the
exact same ZIP file every time, we update the timestamp of the file ``VERSION``
in the source code archive and set the timezone to Europe/Berlin.
In the following example, we'll use the file ``restic-0.10.0.tar.gz`` and Go
1.15.2 to reproduce the released binaries.
In the following example, we'll use the file ``restic-0.12.1.tar.gz`` and Go
1.16.6 to reproduce the released binaries.
1. Determine the Go compiler version used to build the released binaries, then download and extract the Go compiler into ``/usr/local/go``:
.. code::
$ restic version
restic 0.10.0 compiled with go1.15.2 on linux/amd64
restic 0.12.1 compiled with go1.16.6 on linux/amd64
$ cd /usr/local
$ curl -L https://dl.google.com/go/go1.15.2.linux-amd64.tar.gz | tar xz
$ curl -L https://dl.google.com/go/go1.16.6.linux-amd64.tar.gz | tar xz
