Marius van der Wijden	3038e480f5	all: core rework for the merge transition (#23761) ... * all: work for eth1/2 transtition * consensus/beacon, eth: change beacon difficulty to 0 * eth: updates * all: add terminalBlockDifficulty config, fix rebasing issues * eth: implemented merge interop spec * internal/ethapi: update to v1.0.0.alpha.2 This commit updates the code to the new spec, moving payloadId into it's own object. It also fixes an issue with finalizing an empty blockhash. It also properly sets the basefee * all: sync polishes, other fixes + refactors * core, eth: correct semantics for LeavePoW, EnterPoS * core: fixed rebasing artifacts * core: light: performance improvements * core: use keyed field (f) * core: eth: fix compilation issues + tests * eth/catalyst: dbetter error codes * all: move Merger to consensus/, remove reliance on it in bc * all: renamed EnterPoS and LeavePoW to ReachTDD and FinalizePoS * core: make mergelogs a function * core: use InsertChain instead of InsertBlock * les: drop merger from lightchain object * consensus: add merger * core: recoverAncestors in catalyst mode * core: fix nitpick * all: removed merger from beacon, use TTD, nitpicks * consensus: eth: add docstring, removed unnecessary code duplication * consensus/beacon: better comment * all: easy to fix nitpicks by karalabe * consensus/beacon: verify known headers to be sure * core: comments * core: eth: don't drop peers who advertise blocks, nitpicks * core: never add beacon blocks to the future queue * core: fixed nitpicks * consensus/beacon: simplify IsTTDReached check * consensus/beacon: correct IsTTDReached check Co-authored-by: rjl493456442 <garyrong0905@gmail.com> Co-authored-by: Péter Szilágyi <peterke@gmail.com>	3 years ago
Jesse Tane	33f2813809	cmd/geth: add flag --dev.gaslimit for dev mode (#23686) ... * cmd, core: add flag --dev.gaslimit to allow configuring initial block gas limit in dev mode * core: use provided gaslimit Co-authored-by: Martin Holst Swende <martin@swende.se>	3 years ago
ucwong	83e4c49e2b	trie : use trie.NewStackTrie instead of new(trie.Trie) (#22246) ... The PR makes use of the stacktrie, which is is more lenient on resource consumption, than the regular trie, in cases where we only need it for DeriveSha	4 years ago
Marius van der Wijden	6e7137103c	miner: fixed race condition in tests (#21664)	4 years ago
Martin Holst Swende	4eb01b21c8	miner: set etherbase even if mining isn't possible at the moment (#21707)	4 years ago
Martin Holst Swende	1e10489196	miner: don't interrupt mining after successful sync (#21701) ... * miner: exit loop when downloader Done or Failed Following the logic of the comment at the method, this fixes a regression introduced at 7cf56d6f06 , which would allow external parties to DoS with blocks, preventing mining progress. Signed-off-by: meows <b5c6@protonmail.com> * miner: remove ineff assign (lint) Signed-off-by: meows <b5c6@protonmail.com> * miner: update test re downloader events Signed-off-by: meows <b5c6@protonmail.com> * Revert "miner: remove ineff assign (lint)" This reverts commit eaefcd34ab4862ebc936fb8a07578aa2744bc058. * Revert "miner: exit loop when downloader Done or Failed" This reverts commit 23abd34265aa246c38fc390bb72572ad6ae9fe3b. * miner: add test showing imprecise TestMiner Signed-off-by: meows <b5c6@protonmail.com> * miner: fix waitForMiningState precision This helper function would return an affirmation on the first positive match on a desired bool. This was imprecise; it return false positives by not waiting initially for an 'updated' value. This fix causes TestMiner_2 to fail, which is expected. Signed-off-by: meows <b5c6@protonmail.com> * miner: remove TestMiner_2 demonstrating broken test This test demonstrated the imprecision of the test helper function waitForMiningState. This function has been fixed with 6d365c2851, and this test test may now be removed. Signed-off-by: meows <b5c6@protonmail.com> * miner: fix test regarding downloader event/mining expectations See comment for logic. Signed-off-by: meows <b5c6@protonmail.com> * miner: add test describing expectations for downloader/mining events We expect that once the downloader emits a DoneEvent, signaling a successful sync, that subsequent StartEvents are not longer permitted to stop the miner. This prevents a security vulnerability where forced syncs via fake high blocks would stall mining operation. Signed-off-by: meows <b5c6@protonmail.com> * miner: use 'canStop' state to fix downloader event handling - Break downloader event handling into event separating Done and Failed events. We need to treat these cases differently since a DoneEvent should prevent the miner from being stopped on subsequent downloader Start events. - Use canStop state to handle the one-off case when a downloader first succeeds. Signed-off-by: meows <b5c6@protonmail.com> * miner: improve comment wording Signed-off-by: meows <b5c6@protonmail.com> * miner: start mining on downloader events iff not already mining Signed-off-by: meows <b5c6@protonmail.com> * miner: refactor miner update logic w/r/t downloader events This makes mining pause/start logic regarding downloader events more explicit. Instead of eternally handling downloader events after the first done event, the subscription is closed when downloader events are no longer actionable. Signed-off-by: meows <b5c6@protonmail.com> * miner: fix handling downloader events on subcription closed Signed-off-by: meows <b5c6@protonmail.com> * miner: (lint:gosimple) use range over chan instead of for/select Signed-off-by: meows <b5c6@protonmail.com> * miner: refactor update loop to remove race condition The go routine handling the downloader events handling vars in parallel with the parent routine, causing a race condition. This change, though ugly, remove the condition while still allowing the downloader event subscription to be closed when the miner has no further use for it (ie DoneEvent). * miner: alternate fix for miner-flaw Co-authored-by: meows <b5c6@protonmail.com>	4 years ago
Marius van der Wijden	df219e23df	miner: fix regression, add test for starting while download (#21547) ... Fixes a regression introduced in #21536	4 years ago
Marius van der Wijden	7cf56d6f06	miner: use channels instead of atomics in update loop (#21536) ... This PR changes several different things: - Adds test cases for the miner loop - Stops the worker if it wasn't already stopped in worker.Close() - Uses channels instead of atomics in the miner.update() loop Co-authored-by: Felix Lange <fjl@twurst.com>	4 years ago
