Percy Wegmann	17501ea31a	ci: report test coverage to coveralls.io ... This records test coverage for the amd64 no race tests and uploads the results to coveralls.io. Updates #cleanup Signed-off-by: Ox Cart <ox.to.a.cart@gmail.com>	1 year ago
Maisem Ali	56c0a75ea9	tool/gocross: handle VERSION file not found ... Fixes #9734 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
David Anderson	bfe5623a86	tool/gocross: make gocross behave with pre-release Go toolchains ... Also switch the wrapper script to use bash not posix shell. We now depend on bash elsewhere for saner behavior in esoteric areas, so might as well use it everywhere for consistency.

David Anderson	d27a6e1c53	tool/gocross: fix incorrect relpath usage in bootstrap script ... The subshell in which gocross gets built cd's to the corp checkout dir near the top, so all future references to corp repository files should be simple relative paths, and not reference $repo_root. When $repo_root is an absolute path, it doesn't matter and everything works out, but on some OSes and shells and invocations, $repo_root is a completely relative path that is invalidated by the "cd".

James Tucker	8c2b755b2e	tool/gocross: use grep -E over egrep to avoid warning ... Recent egrep builds produce a warning: ``` egrep: warning: egrep is obsolescent; using grep -E ``` Updates #cleanup Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
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.

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	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
