2014-10-14Fix large reorgsPieter Wuille
2014-10-14Fix rebuild-chainstate feature and improve its performancePieter Wuille
Previous refactorings broke the ability to rebuild the chainstate by deleting the chainstate directory, resulting in an incorrect "Incorrect or no genesis block found" error message. Fix that. Also, improve the performance of ActivateBestBlockStep by using the skiplist to only discover a few potential blocks to connect at a time, instead of all blocks forever - as we likely bail out after connecting a single one anyway.
2014-10-14Skip reindexed blocks individuallyPieter Wuille
Instead of skipping to the last reindexed block in each file (which could jump over processed out-of-order blocks), just skip each already processed block individually.
2014-10-14Make -reindex cope with out-of-order blocksWladimir J. van der Laan
Remember out-of-order block headers along with disk positions. This is likely the simplest and least-impact way to make -reindex work with headers first. Based on top of #4468.

2014-10-14RPC additions after headers-firstPieter Wuille
2014-10-14Headers-first synchronizationPieter Wuille
Many changes: * Do not use 'getblocks', but 'getheaders', and use it to build a headers tree. * Blocks are fetched in parallel from all available outbound peers, using a limited moving window. When one peer stalls the movement of the window, it is disconnected. * No more orphan blocks. At all. We only ever request a block for which we have verified the headers, and store it to disk immediately. This means that a disk-fill attack would require PoW. * Require protocol version 31800 for every peer (released in december 2010). * No more syncnode (we sync from everyone we can, though limited to 1 during initial *headers* sync). * Introduce some extra named constants, comments and asserts.

dbca89b Trigger -alertnotify if network is upgrading without you (Gavin Andresen) e01a793 Refactor -alertnotify code (Gavin Andresen) Signed-off-by: Gavin Andresen <gavinandresen@gmail.com>
2014-10-09Trigger -alertnotify if network is upgrading without youGavin Andresen
This adds a -regetest-only undocumented (for regression testing only) command-line option -blockversion=N to set block.nVersion. Adds to the "has the rest of the network upgraded to a block.nVersion we don't understand" code so it calls -alertnotify when 51 of the last 100 blocks are up-version. But it only alerts once, not with every subsequent new, upversion block. And adds a forknotify.py regression test to make sure it works. Tested using forknotify.py: Before adding CAlert::Notify, get: Assertion failed: -alertnotify did not warn of up-version blocks Before adding code to only alert once: Assertion failed: -alertnotify excessive warning of up-version blocks After final code in this pull: Tests successful
2014-10-09Refactor -alertnotify codeGavin Andresen
Refactor common -alertnotify code into static CAlert::Notify method.

2014-10-02Don't translate state.Abort() messagesWladimir J. van der Laan
There is only one message passed to AbortNode() that makes sense to translate to the user specifically: Disk space is low. For the others show a generic message and refer to debug.log for details. Reduces the number of confusing jargon translation messages.

- it now takes over the passed file descriptor and closes it in the destructor - this fixes a leak in LoadExternalBlockFile(), where an exception could cause the file to not getting closed - disallow copies (like recently added for CAutoFile) - make nType and nVersion private

2014-09-24Do merkle root and txid duplicates check simultaneouslyPieter Wuille
Move the txid duplicates check into BuildMerkleTree, where it can be done much more efficiently (without needing to build a full txid set to detect duplicates). The previous version (using the std::set<uint256> to detect duplicates) was also slightly too weak. A block mined with actual duplicate transactions (which is invalid, due to the inputs of the duplicated transactions being seen as double spends) would trigger the duplicates logic, resulting in the block not being stored on disk, and rerequested. This change fixes that by only triggering in the case of duplicated transactions that can actually result in an identical merkle root.
2014-09-24Get rid of the dummy CCoinsViewCache constructor argPieter Wuille
2014-09-23Do not keep fully spent but unwritten CCoins entries cached.Pieter Wuille
Instead of storing CCoins entries directly in CCoinsMap, store a CCoinsCacheEntry which additionally keeps track of whether a particular entry is: * dirty: potentially different from its parent view. * fresh: the parent view is known to not have a non-pruned version. This allows us to skip non-dirty cache entries when pushing batches of changes up, and to remove CCoins entries about transactions that are fully spent before the parent cache learns about them.
2014-09-23Get rid of CCoinsView's SetCoins and SetBestBlock.Pieter Wuille
All direct modifications are now done through ModifyCoins, and BatchWrite is used for pushing batches of queued modifications up, so we don't need the low-level SetCoins and SetBestBlock anymore in the top-level CCoinsView class.
2014-09-23Use ModifyCoins instead of mutable GetCoins.Pieter Wuille
Replace the mutable non-copying GetCoins method with a ModifyCoins, which returns an encapsulated iterator, so we can keep track of concurrent modifications (as iterators can be invalidated by those) and run cleanup code after a modification is finished. This also removes the overloading of the 'GetCoins' name.
