Brad Fitzpatrick	dd97111d06	backoff: update to Go style, document a bit, make 30s explicit Also, bit of behavior change: on non-nil err but expired context, don't reset the consecutive failure count. I don't think the old behavior was intentional. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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

Brad Fitzpatrick	996bf9cae7	logtail: don't send a User-Agent Just useless bytes on the wire. Especially with HTTP/1. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	e71a7c7a2c	logtail: read to EOF on chunked response We'll be fixing the server so this won't trigger in practice, but it demos the connection reuse problem. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

David Crawshaw	6ddbcab71e	logtail: rename the unused CheckLogs to DrainLogs Its semantics has changed slightly, this will let us use it to drive batched logging in special circumstances. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
