Christian Schwarz 1ae087bfcf [WIP] add and use tracing API as part of package logging ... - make `logging.GetLogger(ctx, Subsys)` the authoritative `logger.Logger` factory function - the context carries a linked list of injected fields which `logging.GetLogger` adds to the logger it returns - introduce the concept of tasks and spans, also tracked as linked list within ctx - [ ] TODO automatic logging of span begins and ends, with a unique ID stack that makes it easy to follow a series of log entries in concurrent code - ability to produce a chrome://tracing-compatible trace file, either via an env variable or a `zrepl pprof` subcommand - this is not a CPU profile, we already have go pprof for that - but it is very useful to visually inspect where the replication / snapshotter / pruner spends its time ( fixes #307 )		2020-04-25 11:16:59 +02:00
