gary rong	45cb1a580a	eth, les: add new config field SyncFromCheckpoint (#22123) ... This PR introduces a new config field SyncFromCheckpoint for light client. In some special scenarios, it's required to start synchronization from some arbitrary checkpoint or even from the scratch. So this PR offers this flexibility to users so that the synchronization start point can be configured. There are two relevant configs: SyncFromCheckpoint and Checkpoint. - If the SyncFromCheckpoint is true, the light client will try to sync from the specified checkpoint. - If the Checkpoint is not configured, then the light client will sync from the scratch(from the latest header if the database is not empty) Additional notes: these two configs are not visible in the CLI flags but only accessable in the config file. Example Usage: [Eth] SyncFromCheckpoint = true [Eth.Checkpoint] SectionIndex = 100 SectionHead = "0xabc" CHTRoot = "0xabc" BloomRoot = "0xabc" PS. Historical checkpoint can be retrieved from the synced full node or light client via les_getCheckpoint API.	4 years ago

LES package basically can be divided into LES client and LES server. However both sides will use checkpoint package for status retrieval and verification.

Felix Lange	c213fd1fd8	all: import "context" instead of "golang.org/x/net/context" ... There is no need to depend on the old context package now that the minimum Go version is 1.7. The move to "context" eliminates our weird vendoring setup. Some vendored code still uses golang.org/x/net/context and it is now vendored in the normal way. This change triggered new vet checks around context.WithTimeout which didn't fire with golang.org/x/net/context.	8 years ago
