David Anderson	c9a4dbe383	tool/gocross: correctly embed the git commit into gocross Previously, the build ended up embedding an empty string, which made the shell wrapper rebuild gocross on every invocation. This is still reasonably fast, but fixing the bypass shaves 80% off gocross's overhead when no rebuild is needed. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	e7a78bc28f	tool/gocross: support running from outside the repo dir A bunch of us invoke tool/go from outside the repo that hosts gocross, as a way of accessing our version-controlled toolchain. This removes assumptions from gocross that it's being invoked within the repository that contains its source code and toolchain configuration. Fixes tailscale/corp#9627 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	df02bb013a	tool/gocross: fail if the toolchain revision isn't findable This used to make sense, but after a refactor somewhere along the line this results in trying to download from a malformed URL and generally confusing failures.

David Anderson	0498d5ea86	tool/gocross: delete bootstrap tarball downloads after use Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	1f95bfedf7	tool/gocross: adjust Xcode flags to match new Xcode env Xcode changed how/what data it exports to build steps at some point recently, so our old way of figuring out the minimum support version for clang stopped working. Updates tailscale/corp#4095 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	df3996cae3	tool/gocross: bootstrap correctly on an older toolchain Sometimes, our cached toolchain ends up being an older version of Go, older than our go.mod allows. In that scenario, gocross-wrapper.sh would find a usable toolchain, but then fail to compile gocross. This change makes the wrapper script check that the cached toolchain's minor version is good enough to build tailscale.com, and re-bootstraps in shell if not.

David Anderson	64181e17c8	tool/gocross: support local toolchain for development This makes gocross and its bootstrap script understand an absolute path in go.toolchain.rev to mean "use the given toolchain directly". Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	66621ab38e	tool/gocross: embed the version explicitly with linker flags We need to build gocross from multiple repos, but Go's innate git hash embedding only works when you build gocross from this repo, not when you build it from elsewhere via 'go build tailscale.com/tool/gocross'. Instead, explicitly embed the version found with 'git rev-parse HEAD', which will work from any git repo. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	7444dabb68	tool/gocross: do all the bootstrap steps in a subshell This avoids accidentally overwriting variables from the input environment, which might non-deterministically change the behavior of gocross. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	7e65a11df5	tool/gocross: write the wrapper script directly, rather than printing Turns out directing the printed script into the bootstrap location leads to irritating "text file busy" problems and then having to muck about with tempfiles and chmod and all that. Instead, have gocross write everything with the right values. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	499d82af8a	tool/gocross: add command to print the wrapper shell script So that when importing and using gocross from other repos, there's an easy way to get at the right wrapper script that's in sync with the gocross binary.

David Anderson	860734aed9	tool/gocross: a tool for building Tailscale binaries Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	afe19d1d81	tool/go: don't use the names GOOS/GOARCH in script The use of GOOS to mean "the compiler's host architecture" ends up overriding whatever GOOS the user passed in, resulting in befuddling errors like "unsupported GOOS/GOARCH pair linux/wasm" when the caller requests js/wasm.

David Anderson	02a2dcfc86	go.toolchain.rev: use new statically built toolchain Also removes the toolchain builds from flake.nix. For now the flake build uses upstream Go 1.20, a followup change will switch it back to our custom toolchain. Updates tailscale/corp#9005 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Brad Fitzpatrick	01e736e1d5	go.toolchain.rev: update to Go 1.20rc3 Updates #7123 Change-Id: Ibdf53530251c120e7e20c24abcf4a05f2ff7ac97 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Mihai Parparita	d60f7fe33f	cmd/tsconnect: run wasm-opt on the generated wasm file Saves about 1.4MB from the generated wasm file. The Brotli size is basically unchanged (it's actually slightly larger, by 40K), suggesting that most of the size delta is due to not inlining and other changes that were easily compressible. However, it still seems worthwhile to have a smaller final binary, to reduce parse time and increase likelihood that we fit in the browser's disk cache. Actual performance appears to be unchanged. Updates #5142 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	7e4883b261	.github/workflows: add tsconnect static build to wasm GitHub action Technically not the same as the wasm cross-compilation, but it's closely connected to it. Also includes some fixes to tool/yasm to make it actually work on non-ARM platforms. Fixes #5134 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
James Tucker	7b1a91dfd3	tool/go: accept a marker file with no line terminator Somewhere my local configuration or program versions are producing marker files earlier in the process that lack a line terminator. This doesn't need to cause an exit via set -e, we can just continue the process. $extracted matches $REV anyway, so the process works. Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
Mihai Parparita	be8a0859a9	cmd/tsconnect: pin yarn and node Adds a tool/yarn helper script that uses specific versions of yarn and node, downloading them if necessary. Modeled after tool/go (and the yarn and node Redo scripts from the corp repo). Also allows the path to yarn to be overidden (in case the user does not want to use this script) and always pipes yarn output (to make debugging and viewing of process easier).

Maisem Ali	01a9906bf8	tool/go: add wrapper to download and use go.toolchain.rev go version. Also update build_dist.sh and build_docker.sh to use the wrapper. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
