2023-10-03http: refactor: use encapsulated HTTPRequestTrackerstickies-v
Introduces and uses a HTTPRequestTracker class to keep track of how many HTTP requests are currently active, so we don't stop the server before they're all handled. This has two purposes: 1. In a next commit, allows us to untrack all requests associated with a connection without running into lifetime issues of the connection living longer than the request (see https://github.com/bitcoin/bitcoin/pull/27909#discussion_r1265614783) 2. Improve encapsulation by making the mutex and cv internal members, and exposing just the WaitUntilEmpty() method that can be safely used.

2023-10-02net: reconnect with V1Transport under certain conditionsPieter Wuille
When an outbound v2 connection is disconnected without receiving anything, but at least 24 bytes of our pubkey were sent out (enough to constitute an invalid v1 header), add them to a queue of reconnections to be tried. The reconnections are in a queue rather than performed immediately, because we should not block the socket handler thread with connection creation (a blocking operation that can take multiple seconds).

Original description and commentary can be found there. --- This changeset finishes the first phase of the assumeutxo project. It makes UTXO snapshots loadable via RPC (`loadtxoutset`) and adds `assumeutxo` parameters to chainparams. It contains all the remaining changes necessary to both use an assumedvalid snapshot chainstate and do a full validation sync in the background. This may look like a lot to review, but note that - ~200 lines are a (non-essential) demo shell script - Many lines are functional test, documentation, and relatively dilute RPC code. So it shouldn't be as burdensome to review as the linecount might suggest. - **P2P**: minor changes are made to `init.cpp` and `net_processing.cpp` to make simultaneous IBD across multiple chainstates work. - **Pruning**: implement correct pruning behavior when using a background chainstate - **Blockfile separation**: to prevent "fragmentation" in blockfile storage, have background chainstates use separate blockfiles from active snapshot chainstates to avoid interleaving heights and impairing pruning. - **Indexing**: some `CValidationInterface` events are given with an additional parameter, ChainstateRole, and all indexers ignore events from ChainstateRole::ASSUMEDVALID so that indexation only happens sequentially. - Have `-reindex` properly wipe snapshot chainstates. - **RPC**: introduce RPC commands `loadtxoutset` and (hidden) `getchainstates`. - **Release docs & first assumeutxo commitment**: add notes and a particular assumeutxo hash value for first AU-enabled release. - This will complete the project and allow use of UTXO snapshots for faster node bootstrap. The next phase, if it were to be pursued, would be coming up with a way to distribute the UTXO snapshots over the P2P network. --- ### UTXO snapshots Create your own with `./contrib/devtools/utxo_snapshot.sh`, e.g. ```shell ./contrib/devtools/utxo_snapshot.sh 788000 utxo.dat ./src/bitcoin-cli -datadir=$(pwd)/testdata`) ``` or use the pre-generated ones listed below. - Testnet: **2'500'000** (Sjors): - torrent: `magnet:?xt=urn:btih:511e09f4bf853aefab00de5c070b1e031f0ecbe9&dn=utxo-testnet-2500000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` - sha256: `79db4b025448cc0ac388d8589a28eab02de53055d181e34eb47391717aa16388` - Signet: **160'000** (Sjors): - torrent: `magnet:?xt=urn:btih:9da986cb27b3980ea7fd06b21e199b148d486880&dn=utxo-signet-160000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` - sha256: `eeeca845385ba91e84ef58c09d38f98f246a24feadaad57fe1e5874f3f92ef8c` - Mainnet: **800'000** (Sjors): - Note: this needs the following commit cherry-picked in: https://github.com/Sjors/bitcoin/commit/24deb2022b822f22fba9fcbee201e37a83225eb2 - torrent: `magnet:?xt=urn:btih:50ee955bef37f5ec3e5b0df4cf0288af3d715a2e&dn=utxo-800000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` ### Testing #### For fun (~5min) If you want to do a quick test, you can run `./contrib/devtools/test_utxo_snapshots.sh` and follow the instructions. This is mostly obviated by the functional tests, though. #### For real (longer) If you'd like to experience a real usage of assumeutxo, you can do that too. I've cut a new snapshot at height 788'000 (http://img.jameso.be/utxo-788000.dat - but you can do it yourself with `./contrib/devtools/utxo_snapshot.sh` if you want). Download that, and then create a datadir for testing: ```sh $ cd ~/src/bitcoin # or whatever # get the snapshot $ curl http://img.jameso.be/utxo-788000.dat > utxo-788000.dat # you'll want to do this if you like copy/pasting $ export AU_DATADIR=/home/${USER}/au-test # or wherever $ mkdir ${AU_DATADIR} $ vim ${AU_DATADIR}/bitcoin.conf dbcache=8000 # or, you know, something high blockfilterindex=1 coinstatsindex=1 prune=3000 logthreadnames=1 ``` Obtain this branch, build it, and then start bitcoind: ```sh $ git remote add jamesob https://github.com/jamesob/bitcoin $ git fetch jamesob assumeutxo $ git checkout jamesob/assumeutxo $ ./configure $conf_args && make # (whatever you like to do here) # start 'er up and watch the logs $ ./src/bitcoind -datadir=${AU_DATADIR} ``` Then, in some other window, load the snapshot ```sh $ ./src/bitcoin-cli -datadir=${AU_DATADIR} loadtxoutset $(pwd)/utxo-788000.dat ``` You'll see some log messages about headers retrieval and waiting to see the snapshot in the headers chain. Once you get the full headers chain, you'll spend a decent amount of time (~10min) loading the snapshot, checking it, and flushing it to disk. After all that happens, you should be syncing to tip in pretty short order, and you'll see the occasional `[background validation]` log message go by. In yet another window, you can check out chainstate status with ```sh $ ./src/bitcoin-cli -datadir=${AU_DATADIR} getchainstates ``` as well as usual favorites like `getblockchaininfo`.

2023-10-02rpc: getrawaddrman for addrman entries0xb10c
Exposing address manager table entries in a hidden RPC allows to introspect addrman tables in tests and during development. As response JSON object the following FORMAT1 is choosen: { "table": { "<bucket>/<position>": { "address": "..", "port": .., ... }, "<bucket>/<position>": { "address": "..", "port": .., ... }, "<bucket>/<position>": { "address": "..", "port": .., ... }, ... } } An alternative would be FORMAT2 { "table": { "bucket": { "position": { "address": "..", "port": .., ... }, "position": { "address": "..", "port": .., ... }, .. }, "bucket": { "position": { "address": "..", "port": .., ... }, .. }, } } FORMAT1 and FORMAT2 have different encodings for the location of the address in the address manager. While FORMAT2 might be easier to process for downstream tools, it also mimics internal addrman mappings, which might change at some point. Users not interested in the address location can ignore the location key. They don't have to adapt to a new RPC response format, when the internal addrman layout changes. Additionally, FORMAT1 is also slightly easier to to iterate in downstream tools. The RPC response-building implemenation complexcity is lower with FORMAT1 as we can more easily build a "<bucket>/<position>" key than a multiple "bucket" objects with multiple "position" objects (FORMAT2).

However it may not be valid when a chain is not attached, as happens in the wallet tool and during migration. In such situations, when the conflicting height is also negative (which occurs on loading when no chain is available), the calculation of the number of conflict confirms results in a non-negative value which passes the existing check for valid values. This will subsequently hit an assertion in `GetTxDepthInMainChain`. Furthermore, `MarkConflicted` is also only called on loading a transaction whose parent has a stored state of `TxStateConflicted` and was loaded before the child transaction. This depends on the loading order, which for both sqlite and bdb depends on the txids. We can avoid this by explicitly checking that both `m_last_block_processed_height` and `conflicting_height` are non-negative. Both `tool_wallet.py` and `wallet_migration.py` are updated to create wallets with a state that triggers the assertion.

Currently, every `CKey` object uses 32 such secure bytes, even when the `CKey` object contains the (invalid) value zero. Change this to not use memory when the `CKey` is invalid. This is particularly relevant for `BIP324Cipher` which briefly holds a `CKey`, but after receiving the remote's public key and initializing the encryption ciphers, the key is wiped. In case secure memory usage is in high demand, it'd be silly to waste it on P2P encryption keys instead of wallet keys.

Otherwise we will not receive transactions during background sync until restart.
2023-09-30blockstorage: segment normal/assumedvalid blockfilesJames O'Beirne
When using an assumedvalid (snapshot) chainstate along with a background chainstate, we are syncing two very different regions of the chain simultaneously. If we use the same blockfile space for both of these syncs, wildly different height blocks will be stored alongside one another, making pruning ineffective. This change implements a separate blockfile cursor for the assumedvalid chainstate when one is in use.
2023-09-30validation: populate nChainTx value for assumedvalid chainstatesJames O'Beirne
Use the expected AssumeutxoData in order to bootstrap nChainTx values for assumedvalid blockindex entries in the snapshot chainstate. This is necessary because nChainTx is normally built up from nTx values, which are populated using blockdata which the snapshot chainstate does not yet have.
2023-09-30test: adjust chainstate tests to use recognized snapshot baseJames O'Beirne
In future commits, loading the block index while making use of a snapshot is contingent on the snapshot being recognized by chainparams. Ensure all existing unittests that use snapshots use a recognized snapshot (at height 110). Co-authored-by: Ryan Ofsky <ryan@ofsky.org>
2023-09-30validation: pruning for multiple chainstatesJames O'Beirne

2023-09-30validation: indexing changes for assumeutxoJames O'Beirne
When using an assumedvalid chainstate, only process validationinterface callbacks from the background chainstate within indexes. This ensures that all indexes are built in-order. Later, we can possibly designate indexes which can be built out of order and continue their operation during snapshot use. Once the background sync has completed, restart the indexes so that they continue to index the now-validated snapshot chainstate.

Prior to this patch `FlushBlockFile` may have failed without returning in `Chainstate::FlushStateToDisk`, leading to a potential write from `WriteBlockIndexDB` that may refer to a block that is not fully flushed to disk yet. By returning if either `FlushUndoFile` or `FlushBlockFile` fail, we ensure that no further write operations take place that may lead to an inconsistent database when crashing. Add `[[nodiscard]]` annotations to them such that they are not ignored in future. Functions that call either `FlushUndoFile` or `FlushBlockFile`, need to handle these extra abort cases properly. Since `Chainstate::FlushStateToDisk` already produces an abort error in case of `WriteBlockIndexDB` failing, no extra logic for functions calling `Chainstate::FlushStateToDisk` is required. Besides `Chainstate::FlushStateToDisk`, `FlushBlockFile` is also called by `FindBlockPos`, while `FlushUndoFile` is only called by `FlushBlockFile` and `WriteUndoDataForBlock`. For both these cases, the flush error is not further bubbled up. Instead, the error is logged and a comment is provided why bubbling up an error would be less desirable in these cases. --- This pull request is part of a larger effort towards improving the shutdown / abort / fatal error handling in validation code. It is a first step towards implementing proper fatal error return type enforcement similar as proposed by theuni in this pull request [comment](https://github.com/bitcoin/bitcoin/pull/27711#issuecomment-1563561502). For ease of review of these critical changes, a first step would be checking that `AbortNode` leads to early and error-conveying returns at its call site. Further work for enforcing returns when `AbortNode` is called is done in https://github.com/bitcoin/bitcoin/pull/27862.

e3720bca398820038b3e97f467adb2c45ef9ef5f net: Simplify v2 recv logic by decoupling AAD from state machine (Tim Ruffing) b0f5175c044df956c0f07f540706d457c4912856 net: Drop v2 garbage authentication packet (Tim Ruffing) Pull request description: Note that this is a breaking change, see also https://github.com/bitcoin/bips/pull/1498 The benefit is a simpler implementation: - The protocol state machine does not need separate states for garbage authentication and version phases. - The special case of "ignoring the ignore bit" is removed. - The freedom to choose the contents of the garbage authentication packet is removed. This simplifies testing. ACKs for top commit: naumenkogs: ACK e3720bca398820038b3e97f467adb2c45ef9ef5f sipa: ACK e3720bca398820038b3e97f467adb2c45ef9ef5f.
