Josh Bleecher Snyder	a4e19f2233	version: remove rsc.io/goversion dependency ... rsc.io/goversion is really expensive. Running version.ReadExe on tailscaled on darwin allocates 47k objects, almost 11mb. All we want is the module info. For that, all we need to do is scan through the binary looking for the magic start/end strings and then grab the bytes in between them. We can do that easily and quickly with nothing but a 64k buffer. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a5da4ed981	all: gofmt with Go 1.17 ... This adds "//go:build" lines and tidies up existing "// +build" lines. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
moncho	e101d8396d	portlist, version: update build tags for Go 1.16, Apple M1 ... Build tags have been updated to build native Apple M1 binaries, existing build tags for ios have been changed from darwin,arm64 to ios,arm64. With this change, running go build cmd/tailscale{,d}/tailscale{,d}.go on an Apple machine with the new processor works and resulting binaries show the expected architecture, e.g. tailscale: Mach-O 64-bit executable arm64. Tested using go version go1.16beta1 darwin/arm64. Updates #943 Signed-off-by: moncho <50428+moncho@users.noreply.github.com>	3 years ago
Brad Fitzpatrick	2072dcc127	version: revert the filepath change from earlier commit ... f81233524f changed a use of package 'path' to 'filepath'. Restore it back to 'path', with a comment. Also, use the os.Executable-based fallback name in the case where the binary itself doesn't have Go module information. That was overlooked in the original code.	4 years ago
Avery Pennarun	f81233524f	version/cmdname: s/path/filepath/ and fix version.ReadExe() fallback. ... We were using the Go 'path' module, which apparently doesn't handle backslashes correctly. path/filepath does. However, the main bug turned out to be that we were not calling .Base() on the path if version.ReadExe() fails, which it seems to do at least on Windows 7. As a result, our logfile persistence was not working on Windows, and logids would be regenerated on every restart. Affects: #620 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
