Add RPA Support (#234) * Start adding RPA files. * Update Servers.h -- add batchid for rpc methods * Update Servers.cpp -- add batchId to RPA methods * Update Servers.cpp - add batchId params to generic async * Add key 'rpa' to features map to quell client-side warnings * Code quality fixups and make it compile on latest clang It wasn't compiling at all on latest clang. Also in this commit some code quality fixups and nits, and avoid some double-copies. Also added additional unit testing of prefixSearch & remove functionality. * fix bug * add some sloppy testing code for debug of client Also in this commit: Add files missed by previous merge * Optimize ReusableBlock::serializeInput to be faster This should help reduce CPU usage on initial synch and in general. We added a facility to hash bitcoin objects "in-place", rather than what we were doing before which was serializing them then hashing the serialized bytes. * Refactor - Move the serialization stuff into the .cpp file to avoid header noise and speed up compilation. - Add the trie map thingie into the headers for Fulcrum.pro - Misc. other small nits * Added utility class PackedNumView We will need this later for our new rpa data storage technique. * Added the `Rpa` module This will replace the facilities in `ReusableBlock.cpp` & `.h`. Also ported over the unit tests from `ReusableBlock` to this `Rpa` module. * Tweak to support PackedNumView of 32-bits * Made Rpa::PrefixTable support a read-only "view" into serialized data We will need this in order to quickly be able to read from the DB without too much allocation or other processing to service requests. Also in this commit: - Updated unit tests - Modified GenericVectorReader: added GetPos() and seek() methods * Rpa::PrefixTable ser/deser error path tweak Improved exeption messages and added paranoia check(s) * Some tweaks and additional in-code comments Small refactoring tweaks to the Rpa namespace classes and some small amounts of comments added to document the intention behind the code better. * Small perf. tweak for BTC::Hash2ByteArrayRev And also added some unit tests for various functions we touched/added recently. Also a small nit/refactor in Rpa.h * Removed Jt's Trie-based implementation, swapped in my own Also added some tests and other refactorings. Still TODO: - Mempool handling - Options handling to enable/disable this index - Finish TODOs in comments - Lots of other stuff like maybe an asynch indexing of RPA in the background for servers that are already "up" * Made Rpa logging less verbose by default * Allocate DB memory property for RPA (don't exceed db_mem) Also in this commit, some nits. TODO: If RPA index is disabled, give the memory back to scripthash_unspent and utxoset (which is where we took it from). * Fixed hex parsing bug for blockchain.reusable.* RPCs Turns out our Prefix(uint16, uint8_t) c'tor was buggy due to misplaced parens, so RPC was broken. Fixed. Also added unit tests to test this case as well as others. Also added some perf logging for dev (to be removed later) to the guts function that does the work for blockchain.reusable.get_history. * Nit * Tweaks to unit tests * Added better profile printing for debug, plus 1 nit * Fixed arg parsing for blockchain.reusable.get_history * Added come conf file args for RPA, renamed RPC methods, raised min prefix to 8 bits Conf file args to control various RPA aspects (min prefix, max history, etc) were added. Also, renamed blockchain.reusable.* -> blockchain.rpa.. The old blockchain.reusable names are still supported but are deprecated. We raised the min prefix to 8 bits because 4 is too small and leads to heavy-ish server load on some queries. We also set the number of blocks one can scan with blockchain.rpa.get_history to a limit of 60 by default (configurable), to make for small and light queries to the server. Removed unused #include * Added MempoolPrefixTable Will be used by the mempool. Still needs tests. * Simplified MempoolPrefixTable (it doesn't need 2 associative containers) * Hooked RPA into Mempool; works. Also added "tests" in the mempool bench to use it. * Added some more MempoolPrefixTable unit tests * Added more logic to Storage and Controller to handle RPA - added an "auto" mode that is auto-on for BCH, off for every other coin - user can override this auto mode (which is the default) with a cli or conf file arg - misc nits and fixups Still more to do in this regard. * Added rpa_start_height conf option Suppress indexing until this height. Defaults to -1 which means "Automatic" and is height 825,000 for mainnet, 0 for all other nets. * Tweaks to RPA max history code - Re-use the history-too-large lambda mechanism we use in getHistory() - Have rpa_max_history inherit max_history if max_history was specified and rpa_max_history was not (since this is what users might expect). * Refactor and fixups to getRpaHistory() Made the RPC to blockchain.rpa.get_history take params in the same from,to way as blockchain.scripthash.get_history. blockchain.reusable.get_history still works like the old way. Neither of them return mempool (unlike .scripthash.get_history). Also switched the getRpaHistory() function to use a rocksdb iterator to scan records in sequence, since this should in theory be faster than individual O(log N) db gets. Also other minor fixes. Tweak to getRpaHistory() Just forward the iterator 1 item at a time since it should be faster. Also refine the logic to not append mempool unconditionally if we didn't hit tipHeight in the confirmed scan (branch not currently used). * Optimized PackedNumView deserialization Use built-in byteswap functions rather than looping and doing it ourselves. Should be faster. * Optimized PackedNumView::Make Leverage byteswap calls that are possibly-no-ops is host and destination byte order match, and even if they don't, should be faster anyway than our hand-crafted loops that achieve same. * Added some Rpa stats tracking in Storage.cpp And also loading the DB now does faster checks. Still todo: use firstHeight and lastHeight from DB to decide if/how to (re)synch the index on app startup. * Fleshed out the initial check of the RPA db more, still more to do. We need to now have a way to synch the index separately in Controller.. and handle all corner cases that may arise. * Fixes and nits, mainly in loadCheckRpaDB * Small nits and header cleanup * Added method getRpaDBHeightRange to Storage May be useful later for the Controller. * wip * Refactored code that puts RPA data into DB into a function It's now in Storage::addRpaDataForHeight_nolock, since it does some defensive sanity checking. * Added 2 fields to RpaOnlyModeData * Got RPA index sync independent of block sync working It needs work in recovering from DL failure and other corner cases but it basically works. * Solved the last of the consistency corner cases on RPA index synch I'm pretty sure we are solid now and the RPA index eventally synchs separate of the general block download on config change. Meaning users get a decent experience with the index if they play with enabled/disabled toggling. * Bumped version to 1.10.0 This is due to the addition of the RPA index facility. Also bumped protocol version to 1.5.3 due to addition of new RPA RPCs. * Fixed percent display for RPA Index synch It really should be a percentage of the current download progress and not a full blockchain percentage as the normal blocks synch is. Fixed. * Corrected a debug string message * Took the bitcoin byte swap functions out of the `bitcoin` namespace This is because on some platforms they are actually #defines to some global thing, so eg `bitcoin::htole16` was failing to compile on such platforms. * Fixed some compile issue on Ubuntu 22 GCC-11 + Qt5 didn't like some of the stuff we did in recent commits. Fixed. * Fixed a failing test: `rpcmsgid` for Linux * Follow-up * Disabled the rpa subscribe/unsubscribe RPC methods (for now) They are unimplemented anyway and no clients use them (for now). * 2 nits * Fixed a potential bug * Renamed a /debug endpoint key * Some rename rpa_history_blocks_limit -> rpa_history_blocks And also some other minor tweaks. Mostly a renaming/nit commit. * A small refactoring of some boilerplate * Added docs for RPA options to example conf file in docs/ dir. * Made the rpa.get_history call use [from, to) (exclusive) range This is more akin to how existing calls operate. Also updated the electrum-cash-protocol submodule pointer to latest. * Updated electrum-cash-protocol submodule pointer * Update to electurm-cash-protocol module copyright * Got rid of some dead code and updated some comments * Corrected a comment --------- Co-authored-by: = <=jonaldfyookball@outlook.com> Co-authored-by: fyookball <jonaldfyookball@outlook.com> Co-authored-by: blockparty <hello@blockparty.sh> 2024-03-04 02:16:27 +02:00			`<RCC>`
