Avery Pennarun	db051fb013	ipnserver and logpolicy: configure zstd with low-memory settings. ... The compressed blobs we send back and forth are small and infrequent, which doesn't justify the 8MB * GOMAXPROCS memory that was being allocated. This was the overwhelming majority of memory use in tailscaled. On my system it goes from ~100M RSS to ~15M RSS (which is still suspiciously high, but we can worry about that more later).

Avery Pennarun	08acb502e5	Add tstest.PanicOnLog(), and fix various problems detected by this. ... If a test calls log.Printf, 'go test' horrifyingly rearranges the output to no longer be in chronological order, which makes debugging virtually impossible. Let's stop that from happening by making log.Printf panic if called from any module, no matter how deep, during tests. This required us to change the default error handler in at least one http.Server, as well as plumbing a bunch of logf functions around, especially in magicsock and wgengine, but also in logtail and backoff. To add insult to injury, 'go test' also rearranges the output when a parent test has multiple sub-tests (all the sub-test's t.Logf is always printed after all the parent tests t.Logf), so we need to screw around with a special Logf that can point at the "current" t (current_t.Logf) in some places. Probably our entire way of using subtests is wrong, since 'go test' would probably like to run them all in parallel if you called t.Parallel(), but it definitely can't because the're all manipulating the shared state created by the parent test. They should probably all be separate toplevel tests instead, with common setup/teardown logic. But that's a job for another time. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago

Brad Fitzpatrick	9497921f52	logpolicy: also set up TLS dialing (for iOS) for log uploads ... This was the last of the three places that do TLS from clients (logs, control, derp). With this, iOS should be able to use the memory-efficient x509 root CertPool.	5 years ago

David Anderson	15b4d26d92	logpolicy: automatically figure out paths and filenames. ... The autoselection should pick sensible paths for all of: - Windows (LocalAppData) - Mac (Library/Caches) - Unix user (XDG_CACHE_DIR) - Linux systemd service (CACHE_DIRECTORY) As a last resort, if cache dir lookup fails, plops sufficiently uniquely named files into the current working directory.
