* cmd, eth: Added in the flag to step geth once sync based on input
* cmd, eth: 16400 Add an option to stop geth once in sync.
* cmd: 16400 Add an option to stop geth once in sync. WIP
* cmd/geth/main, les/fletcher: added in light mode support
* cmd/geth/main, les/fletcher: Cleaned Comments and code for light mode
* cmd: 16400 Fixed formatting issue and cleaned code
* cmd, eth, les: 16400 Fixed formatting issues
* cmd, eth, les: Performed gofmt to update formatting
* cmd, eth, les: Fixed bugs resulting formatting
* cmd/geth, eth/, les: switched to downloader event
* eth: Fixed styling and gen_config
* eth/: Fix nil error in config file
* cmd/geth: Updated countdown log
* les/fetcher.go: Removed depcreated channel
* eth/downloader.go: Removed deprecated select
* cmd/geth, cmd/utils: Fixed minor issues
* eth: Reverted config files to proper format
* eth: Fixed typo in config file
* cmd/geth, eth/down: Updated code to use header time stamp
* eth/downloader: Changed the time threshold to 10 minutes
* cmd/geth, eth/downloader: Updated downloading event to pass latest header
* cmd/geth: Updated main to use right timer object
* cmd/geth: Removed unused failed event
* cmd/geth: added in correct time field with type assertion
* cmd/geth, cmd/utils: Updated flag to use boolean
* cmd/geth, cmd/utils, eth/downloader: Cleaned up code based on recommendations
* cmd/geth: Removed unneeded import
* cmd/geth, eth/downloader: fixed event field and suggested changes
* cmd/geth, cmd/utils: Updated flag and linting issue
* core: speed up GenerateChain
Use a mock implementation of ChainReader instead of creating
and destroying a BlockChain object for each generated block.
* eth/downloader: speed up tests by generating chain only once
This change reworks the downloader tests so they share a common test
blockchain instead of generating a chain in every test. The tests are
roughly twice as fast now.
This removes a golint warning: type name will be used as trie.TrieSync by
other packages, and that stutters; consider calling this Sync.
In hexToKeybytes len(hex) is even and (even+1)/2 == even/2, remove the +1.
Updated use of Parallel and added some subtests to help isolate
them. Increased timeout in RequestHeadersByNumber so it
doesn't time out and causes other tests to break.
* ethdb: add Putter interface and Has method
* ethdb: improve docs and add IdealBatchSize
* ethdb: remove memory batch lock
Batches are not safe for concurrent use.
* core: use ethdb.Putter for Write* functions
This covers the easy cases.
* core/state: simplify StateSync
* trie: optimize local node check
* ethdb: add ValueSize to Batch
* core: optimize HasHeader check
This avoids one random database read get the block number. For many uses
of HasHeader, the expectation is that it's actually there. Using Has
avoids a load + decode of the value.
* core: write fast sync block data in batches
Collect writes into batches up to the ideal size instead of issuing many
small, concurrent writes.
* eth/downloader: commit larger state batches
Collect nodes into a batch up to the ideal size instead of committing
whenever a node is received.
* core: optimize HasBlock check
This avoids a random database read to get the number.
* core: use numberCache in HasHeader
numberCache has higher capacity, increasing the odds of finding the
header without a database lookup.
* core: write imported block data using a batch
Restore batch writes of state and add blocks, tx entries, receipts to
the same batch. The change also simplifies the miner.
This commit also removes posting of logs when a forked block is imported.
* core: fix DB write error handling
* ethdb: use RLock for Has
* core: fix HasBlock comment
