2017-10-13Merge #11456: Replace relevant services logic with a function suite.Pieter Wuille
15f5d3b17 Switch DNSSeed-needed metric to any-automatic-nodes, not services (Matt Corallo) 5ee88b4bd Clarify docs for requirements/handling of addnode/connect nodes (Matt Corallo) 57edc0b0c Rename fAddnode to a more-descriptive "manual_connection" (Matt Corallo) 44407100f Replace relevant services logic with a function suite. (Matt Corallo) Pull request description: This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman. Adds HasAllRelevantServices and GetRelevantServices, which check for NETWORK|WITNESS. This changes the following: * Removes nRelevantServices from CConnman, disconnecting it a bit more from protocol-level logic. * Replaces our sometimes-connect-to-!WITNESS-nodes logic with simply always requiring WITNESS|NETWORK for outbound non-feeler connections (feelers still only require NETWORK). * This has the added benefit of removing nServicesExpected from CNode - instead letting net_processing's VERSION message handling simply check HasAllRelevantServices. * This implies we believe WITNESS nodes to continue to be a significant majority of nodes on the network, but also because we cannot sync properly from !WITNESS nodes, it is strange to continue using our valuable outbound slots on them. * In order to prevent this change from preventing connection to -connect= nodes which have !WITNESS, -connect nodes are now given the "addnode" flag. This also allows outbound connections to !NODE_NETWORK nodes for -connect nodes (which was already true of addnodes). * Has the (somewhat unintended) consequence of changing one of the eviction metrics from the same sometimes-connect-to-!WITNESS-nodes metric to requiring HasRelevantServices. This should make NODE_NETWORK_LIMITED much simpler to implement.

This commit introduces a phased removal of RPC methods. RPC method is disabled by default in version x, but can be enabled by using the `-deprecatedrpc=<methodname>` argument. RPC method is removed entirely in version (x+1). This gives users fair warning that an RPC is to be removed, and time to change client software if necessary. Deprecation warnings in RPC return values or release notes are easily ignored. This is a more generic version of the approach I tried to use in #10841, which too late to make it into v0.15.

Currently, however, it is buggy in two ways: 1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite. 2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other. Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

This more clearly uses fReindex vs fReset to make sure we're not clearing our coinsdb needlessly when restarting after a reindex. It also makes it so that restarting after shutting down mid-reindex isn't treates specially at all during txdb loading code, as it shouldn't be.

(Matt Corallo) Pull request description: This does a number of things to clean up chainstate init order, fixing some issues as it goes: * Order chainstate init more logically - first all of the blocktree-related loading, then coinsdb, then pcoinsTip/chainActive. Only create objects as needed. * More clearly document exactly what is and isn't called in -reindex and -reindex-chainstate both with comments noting calls as no-ops and by adding if guards. * Move the writing of fTxIndex to LoadBlockIndex - this fixes a bug introduced in d6af06d68aae985436cbc942f0d11078041d121b where InitBlockIndex was writing to fTxIndex which had not yet been checked (because LoadChainTip hadn't yet initialized the chainActive, which would otherwise have resulted in InitBlockIndex being a NOP), allowing you to modify -txindex without reindex, potentially corrupting your chainstate! * Rename InitBlockIndex to LoadGenesisBlock, which is now a more natural name for it. Also check mapBlockIndex instead of chainActive, fixing a bug where we'd write the genesis block out on every start. * Move LoadGenesisBlock further down in init. This is a more logical location for it, as it is after all of the blockindex-related loading and checking, but before any of the UTXO-related loading and checking. * Give LoadChainTip a return value - allowing it to indicate that the UTXO DB ran ahead of the block DB. This just provides a nicer error message instead of the previous mysterious assert(!setBlockIndexCandidates.empty()) error. * Calls ActivateBestChain in case we just loaded the genesis block in LoadChainTip, avoiding relying on the ActivateBestChain in ThreadImport before continuing init process. * Move all of the VerifyDB()-related stuff into a -reindex + -reindex-chainstate if guard. It couldn't do anything useful as chainActive.Tip() would be null at this point anyway.

2017-07-27Fix segfault when shutting down before fully loadingMatt Corallo
This was introduced by 3192975f1d177aa9f0bbd823c6387cfbfa943610. It can be triggered easily when canceling DB upgrade from pre-per-utxo.
2017-07-27Order chainstate init more logically.Matt Corallo
* Order chainstate init more logically - first all of the blocktree-related loading, then coinsdb, then pcoinsTip/chainActive. Only create objects as needed. * More clearly document exactly what is and isn't called in -reindex and -reindex-chainstate both with comments noting calls as no-ops and by adding if guards. * Move LoadGenesisBlock further down in init. This is a more logical location for it, as it is after all of the blockindex-related loading and checking, but before any of the UTXO-related loading and checking. * Move all of the VerifyDB()-related stuff into a -reindex + -reindex-chainstate if guard. It couldn't do anything useful as chainActive.Tip() would be null at this point anyway.
2017-07-27Call RewindBlockIndex even if we're about to run -reindex-chainstateMatt Corallo
RewindBlockIndex works over both chainActive - disconnecting blocks from the tip that need witness verification - and mapBlockIndex - requiring redownload of blocks missing witness data. It should never have been the case that the second half is skipped if we're about to run -reindex-chainstate.
2017-07-27More user-friendly error message if UTXO DB runs ahead of block DBMatt Corallo
This gives LoadChainTip a return value - allowing it to indicate that the UTXO DB ran ahead of the block DB. This just provides a nicer error message instead of the previous mysterious assert(!setBlockIndexCandidates.empty()) error. This also calls ActivateBestChain in case we just loaded the genesis block in LoadChainTip, avoiding relying on the ActivateBestChain in ThreadImport before continuing init process.
