Elias Naur	bca9fe35ba	logtail: return correct write size from logger.Write Signed-off-by: Elias Naur <mail@eliasnaur.com>	4 years ago
Avery Pennarun	6f590f5b52	logtail: we missed a case for the backoff timer. We want to run bo.Backoff() after every upload, regardless. If upload==true but err!=nil, we weren't backing off, which caused some very-high-throughput log upload retries in bad network conditions. Updates #282.

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
Avery Pennarun	64db026c8b	backoff: add a LogLongerThan configuration. Some programs use frequent short-duration backoffs even under non-error conditions. They can set this to avoid logging short backoffs when things are operating normally, but still get messages when longer backoffs kick in.
