David Crawshaw	eab80e3877	logpolicy: only log panics when running under systemd Given that https://github.com/golang/go/issues/42888 is coming, this catches most practical panics without interfering in our development environments. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	3e039daf95	logpolicy: actually collect panics (Written with Josh) For #2544 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Josh Bleecher Snyder	0aa77ba80f	tstest/integration: fix filch test flake Filch doesn't like having multiple processes competing for the same log files (#937). Parallel integration tests were all using the same log files. Add a TS_LOGS_DIR env var that the integration test can use to use separate log files per test. Fixes #2269 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	98f9e82c62	logpolicy: on Windows, use tailscale-ipn log name if it already existed For the migration to tailscaled.exe on Windows, don't create a new logid if one existed under the old filename. Updates #1232	4 years ago

Brad Fitzpatrick	57dd247376	cmd/tailscaled, logpolicy, logtail: support log levels Log levels can now be specified with "[v1] " or "[v2] " substrings that are then stripped and filtered at the final logger. This follows our existing "[unexpected]" etc convention and doesn't require a wholesale reworking of our logging at the moment. cmd/tailscaled then gets a new --verbose=N flag to take a log level that controls what gets logged to stderr (and thus systemd, syslog, etc). Logtail is unaffected by --verbose. This commit doesn't add annotations to any existing log prints. That is in the next commit.

David Anderson	54e6c3a290	version: use OSS repo's version when building. When building with redo, also include the git commit hash from the proprietary repo, so that we have a precise commit that identifies all build info (including Go toolchain version). Add a top-level build script demonstrating to downstream distros how to burn the right information into builds. Adjust `tailscale version` to print commit hashes when available. Fixes #841.

Brad Fitzpatrick	6013462e9e	logpolicy: remove inaccurate comment, conditional tryFixLogStateLocation call What I was probably actually hitting was exe caching issues where the binary was updated on a SMB shared drive and I tried to run it with the GUI exe still open, so Windows blends the two pages together and causes all sorts of random corruption. I didn't know about that at the time. Now, just call tryFixLogStateLocation unconditionally. The func itself will bail out early on non-applicable OSes. (And rearrange it to return even a bit earlier.)	4 years ago
David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

Brad Fitzpatrick	c3f7733f53	logpolicy: don't check version.CmdName on Windows unnecessarily ... it was crashing for some reason, running out of stack while loading a DLL in goversion. I don't understand Windows (or the Go runtime for Windows) enough to know why that'd be problematic in that context. In any case, don't call it, as tryFixLogStateLocation does nothing on Windows anyway. tryFixLogStateLocation should probably just call version.CmdName itself if/when it needs to, after the GOOS check.	4 years ago

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.
