[beta] More backports for 2.1.2 (#9733)
* produce portable binaries (#9725) * HF in POA Core (2018-10-22) (#9724) poanetwork/poa-chain-spec#87 * Use static call and apparent value transfer for block reward contract code (#9603) * Verify block syncing responses against requests (#9670) * sync: Validate received BlockHeaders packets against stored request. * sync: Validate received BlockBodies and BlockReceipts. * sync: Fix broken tests. * sync: Unit tests for BlockDownloader::import_headers. * sync: Unit tests for import_{bodies,receipts}. * tests: Add missing method doc. * Fix ancient blocks sync (#9531) * Log block set in block_sync for easier debugging * logging macros * Match no args in sync logging macros * Add QueueFull error * Only allow importing headers if the first matches requested * WIP * Test for chain head gaps and log * Calc distance even with 2 heads * Revert previous commits, preparing simple fix This reverts commit 5f38aa8. * Reject headers with no gaps when ChainHead * Reset block sync download when queue full * Simplify check for subchain heads * Add comment to explain subchain heads filter * Fix is_subchain_heads check and comment * Prevent premature round completion after restart This is a problem on mainnet where multiple stale peer requests will force many rounds to complete quickly, forcing the retraction. * Reset stale old blocks request after queue full * Revert "Reject headers with no gaps when ChainHead" This reverts commit 0eb8655. * Add BlockSet to BlockDownloader logging Currently it is difficult to debug this because there are two instances, one for OldBlocks and one for NewBlocks. This adds the BlockSet to all log messages for easy log filtering. * Reset OldBlocks download from last enqueued Previously when the ancient block queue was full it would restart the download from the last imported block, so the ones still in the queue would be redownloaded. Keeping the existing downloader instance and just resetting it will start again from the last enqueued block.:wq * Ignore expired Body and Receipt requests * Log when ancient block download being restarted * Only request old blocks from peers with >= difficulty #9226 might be too permissive and causing the behaviour of the retraction soon after the fork block. With this change the peer difficulty has to be greater than or euqal to our syncing difficulty, so should still fix #9225 * Some logging and clear stalled blocks head * Revert "Some logging and clear stalled blocks head" This reverts commit 757641d. * Reset stalled header if useless more than once * Store useless headers in HashSet * Add sync target to logging macro * Don't disable useless peer and fix log macro * Clear useless headers on reset and comments * Use custom error for collecting blocks Previously we resued BlockImportError, however only the Invalid case and this made little sense with the QueueFull error. * Remove blank line * Test for reset sync after consecutive useless headers * Don't reset after consecutive headers when chain head * Delete commented out imports * Return DownloadAction from collect_blocks instead of error * Don't reset after round complete, was causing test hangs * Add comment explaining reset after useless * Replace HashSet with counter for useless headers * Refactor sync reset on bad block/queue full * Add missing target for log message * Fix compiler errors and test after merge * ethcore: revert ethereum tests submodule update * Add hardcoded headers (#9730) * add foundation hardcoded header #6486017 * add ropsten hardcoded headers #4202497 * add kovan hardcoded headers #9023489 * gitlab ci: releasable_branches: change variables condition to schedule (#9729)
