Danny Kopping	6bf5b5d8c1	Use a line-buffered logger to deamplify write syscalls (#6954 ) We initialise a global logger in `pkg/util/log/log.go` and use it extensively throughout the Loki codebase. Every time we write a log message, a `write` syscall is invoked. Syscalls are problematic because they transition the process from userspace to kernelspace, which means: - a context-switch is incurred, which is inherently expensive ([1-2 microseconds](https://eli.thegreenplace.net/2018/measuring-context-switching-and-memory-overheads-for-linux-threads/)) - the goroutine executing the code is blocked - the underlying OS thread (_M_ in the go scheduler model) is also blocked - the goroutine has to be rescheduled once the syscall exits - the go scheduler may need to spawn additional OS threads if all are blocked in syscalls - which can also be expensive This change introduces the use of a line-buffered logger. It has a buffer of [256](https://gist.github.com/dannykopping/0704db32c0b08751d1d2494efaa734c2) entries, and once that buffer is filled it will flush to disk. However, a situation will arise in which that buffer remains somewhat empty for a period of time, so there is a periodic flush mechanism, configured to flush every 100ms. There is also a preallocated bytes slice of 10MB which is reused, to avoid excessive slice resizing & garbage collection. This does mean that we could lose up to 256 log messages in case of an ungraceful termination of the process, but this would need to be precisely timed within the 100ms flushes - in other words, the likelihood is low, and generally we shouldn't `kill -9` any Loki process.	3 years ago

Ed Welch	2ac409c23e	Build: simplify how protos are built (#4639 ) * we always seem to be chasing our tails with how protos are generated and Makes use of timestamps to determine if files should be recompiled. Instead of touching files and altering timestamps always delete the compiled proto files when calling `protos` to make sure they are compiled every time. Removed targets to build protos, yaccs, and ragel files when trying to build loki or the canary. This isn't necesary, if you are changing these files you would know you need to build them and the `check-generated-files` should catch any changes to them not committed. * rm -rf * we have a race between check-generated-files and our other steps, so let that run first. also removing `check-generated-files` from the `all` target because its redundant with a separate step and could also race with the parallel lint * remove TOUCH_PROTOS * more cleanup of TOUCH_PROTOS	4 years ago
