Marten Seemann 514411bedb feat: opt-in Swarm.ResourceMgr (go-libp2p v0.18) (#8680) ... * update go-libp2p to v0.18.0 * initialize the resource manager * add resource manager stats/limit commands * load limit file when building resource manager * log absent limit file * write rcmgr to file when IPFS_DEBUG_RCMGR is set * fix: mark swarm limit|stats as experimental * feat(cfg): opt-in Swarm.ResourceMgr This ensures we can safely test the resource manager without impacting default behavior. - Resource manager is disabled by default - Default for Swarm.ResourceMgr.Enabled is false for now - Swarm.ResourceMgr.Limits allows user to tweak limits per specific scope in a way that is persisted across restarts - 'ipfs swarm limit system' outputs human-readable json - 'ipfs swarm limit system new-limits.json' sets new runtime limits (but does not change Swarm.ResourceMgr.Limits in the config) Conventions to make libp2p devs life easier: - 'IPFS_RCMGR=1 ipfs daemon' overrides the config and enables resource manager - 'limit.json' overrides implicit defaults from libp2p (if present) * docs(config): small tweaks * fix: skip libp2p.ResourceManager if disabled This ensures 'ipfs swarm limit|stats' work only when enabled. * fix: use NullResourceManager when disabled This reverts commit b19f7c9eca. after clarification feedback from https://github.com/ipfs/go-ipfs/pull/8680#discussion_r841680182 * style: rename IPFS_RCMGR to LIBP2P_RCMGR preexisting libp2p toggles use LIBP2P_ prefix * test: Swarm.ResourceMgr * fix: location of opt-in limit.json and rcmgr.json.gz Places these files inside of IPFS_PATH * Update docs/config.md * feat: expose rcmgr metrics when enabled (#8785) * add metrics for the resource manager * export protocol and service name in Prometheus metrics * fix: expose rcmgr metrics only when enabled Co-authored-by: Marcin Rataj <lidel@lidel.org> * refactor: rcmgr_metrics.go * refactor: rcmgr_defaults.go This file defines implicit limit defaults used when Swarm.ResourceMgr.Enabled We keep vendored copy to ensure go-ipfs is not impacted when go-libp2p decides to change defaults in any of the future releases. * refactor: adjustedDefaultLimits Cleans up the way we initialize defaults and adds a fix for case when connection manager runs with high limits. It also hides `Swarm.ResourceMgr.Limits` until we have a better understanding what syntax makes sense. * chore: cleanup after a review * fix: restore go-ipld-prime v0.14.2 * fix: restore go-ds-flatfs v0.5.1 Co-authored-by: Lucas Molas <schomatis@gmail.com> Co-authored-by: Marcin Rataj <lidel@lidel.org>		2022-04-07 21:06:35 -04:00
