David Anderson 9cd4e65191 smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale code. It currently includes the Linux client.

The Linux client is currently cmd/relaynode, but will soon be replaced by cmd/tailscaled.

Using

We serve packages for a variety of distros at https://pkgs.tailscale.com .

Building

go install tailscale.com/cmd/tailscale{,d}

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.14) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.
