00e9b97f37e0bdf4c647236838c10b68b7ad5be3 refactor: Move fs.* to util/fs.* (TheCharlatan) 106b46d9d25b5228ef009fbbe6f9a7ae35090d15 Add missing fs.h includes (TheCharlatan) b202b3dd6393b415fa68e18dc49c9431dc6b58b2 Add missing cstddef include in assumptions.h (TheCharlatan) 18fb36367a28819bd5ab402344802796a1248979 refactor: Extract util/fs_helpers from util/system (Ben Woosley) Pull request description: This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303 https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". This commit was originally authored by empact and is taken from its parent PR #25152. #### Context There is an ongoing effort to decouple the `ArgsManager` used for command line parsing user-provided arguments from the libbitcoinkernel library (https://github.com/bitcoin/bitcoin/pull/25290, https://github.com/bitcoin/bitcoin/pull/25487, https://github.com/bitcoin/bitcoin/pull/25527, https://github.com/bitcoin/bitcoin/pull/25862, https://github.com/bitcoin/bitcoin/pull/26177, and https://github.com/bitcoin/bitcoin/pull/27125). The `ArgsManager` is defined in `system.h`. A similar pull request extracting functionality from `system.h` has been merged in https://github.com/bitcoin/bitcoin/pull/27238. #### Changes Next to providing better code organization, this PR removes some reliance of the tree of libbitcoinkernel header includes on `system.h` (and thus the `ArgsManager` definition) by moving filesystem related functions out of the `system.*` files. There is already a pair of `fs.h` / `fs.cpp` in the top-level `src/` directory. They were not combined with the files introduced here, to keep the patch cleaner and more importantly because they are often included without the utility functions. The new files are therefore named `fs_helpers` and the existing `fs` files are moved into the util directory. Further commits splitting more functionality out of `system.h` are still in #25152 and will be submitted in separate PRs once this PR has been processed.

2023-03-23refactor: Move fs.* to util/fs.*TheCharlatan
The fs.* files are already part of the libbitcoin_util library. With the introduction of the fs_helpers.* it makes sense to move fs.* into the util/ directory as well.
2023-03-23refactor: Extract util/fs_helpers from util/systemBen Woosley
This is an extraction of filesystem related functions from util/system into their own utility file. The background of this commit is an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager defined in system.h. Moving these functions out of system.h allows including them from a separate source file without including the ArgsManager definitions from system.h.

Devs were [suprised to realize](https://twitter.com/jamesob/status/1637237917201383425) last night that we don't have definitive logging for when a given header was first received. This logs to the main stream when new headers are received outside of IBD, as well as when headers come in over cmpctblocks. The rationale of not hiding these under log categories is that they may be useful to have widely available when debugging strange network activity, and the marginal volume is modest.

Usage is demonstrated in the example script `contrib/tracing/mempool_monitor.py`. Interface tests are provided in `test/functional/interface_usdt_mempool.py`. The rationale for passing the removal reason as a string instead of numerically is that the benefits of not having to maintain a redundant enum-string mapping seem to outweigh the small cost of string generation. The reject reason is passed as string as well, although in this instance the string does not have to be generated but is readily available.

2023-03-20Add mempool tracepointsvirtu
Tracepoints for added, removed, replaced, and rejected transactions. The removal reason is passed as string instead of a numeric value, since the benefits of not having to maintain a redundant enum-string mapping seem to outweigh the small cost of string generation. The reject reason is passed as string as well, although here the string does not have to be generated but is readily available. So far, tracepoint PRs typically included two demo scripts: a naive bpftrace script to show raw tracepoint data and a bcc script for a more refined view. However, as some of the ongoing changes to bpftrace introduce a certain degree of unreliability (running some of the existing bpftrace scripts was not possible with standard kernels and bpftrace packages on latest stable Ubuntu, Debian, and NixOS), this PR includes only a single bcc script that fuses the functionality of former bpftrace and bcc scripts.

This is not optimal, since as a stand-alone library it should not rely on bitcoind's argument parsing logic. Instead, its interfaces should accept control and options structs that control the kernel library's desired configuration. Similar work towards decoupling the `ArgsManager` from the kernel has been done in https://github.com/bitcoin/bitcoin/pull/25290, https://github.com/bitcoin/bitcoin/pull/25487, https://github.com/bitcoin/bitcoin/pull/25527 and https://github.com/bitcoin/bitcoin/pull/25862. #### Changes By moving the `CChainParams` class definition into the kernel and giving it new factory functions `CChainParams::{RegTest,SigNet,Main,TestNet}`it can be constructed without an `ArgsManager` reference, unlike the current factory function `CreateChainParams`. The first few commits remove uses of `ArgsManager` within `CChainParams`. Then the `CChainParams` definition is moved to a new file in the `kernel/` subdirectory.

The chainstatemanager m_options.chainparams member variable gets its value from the global chainparams in init.cpp. This allows validation.cpp to only include the the kernel chainparams file.

Simultaneously in the background, the already-existing chainstate continues "conventional" IBD to both accumulate full block data and serve as a belt-and-suspenders to validate the assumed-valid chainstate. Once the background chainstate's tip reaches the base block of the snapshot used, we set `m_stop_use` on that chainstate and immediately take the hash of its UTXO set; we verify that this matches the assumeutxo value in the source code. Note that while we ultimately want to remove this background chainstate, we don't do so until the following initialization process, when we again check the UTXO set hash of the background chainstate, and if it continues to match, we remove the (now unnecessary) background chainstate, and move the (previously) assumed-valid chainstate into its place. We then reinitialize the chainstate in the normal way. As noted in previous comments, we could do the filesystem operations "inline" immediately when the background validation completes, but that's basically just an optimization that saves disk space until the next restart. It didn't strike me as worth the risk of moving chainstate data around on disk during runtime of the node, though maybe my concerns are overblown. The final result of this completion process is a fully-validated chain, where the only evidence that the user synced using assumeutxo is the existence of a `base_blockhash` file in the `chainstate` directory.

However, if the user actively specifies one of these args, we return with an InitError if we can't complete the check. This PR also changes `-verifychain` RPC to return `false` if the verification didn't finish due to missing block data (pruning) or due to being interrupted by the node being shutdown. Previously, this PR also included a fix for a possible assert during verification - this was done in #27009 (now merged).

2023-02-22validation: add CChainState::m_disabled and ChainMan::isUsableJames O'Beirne
and remove m_snapshot_validated. This state can now be inferred by the number of isUsable chainstates. m_disabled is used to signal that a chainstate should no longer be used by validation logic; it is used as a sentinel when background validation completes or if the snapshot chainstate is found to be invalid. isUsable is a convenience method that incorporates m_disabled.

2023-02-16validation: report if pruning prevents completion of verificationMartin Zumsande
Now the verifychain RPC returns false if the checks didn't finish because the blocks requested to be queried have been pruned.
2023-02-16init, validation: Improve handling if VerifyDB() fails due to insufficient ↡Martin Zumsande
dbcache The rpc command verifychain now fails if the dbcache was not sufficient to complete the verification at the specified level and depth. In the same situation, the VerifyDB check during Init will now fail (and lead to an early shutdown) if the user has explicitly specified -checkblocks or -checklevel but the check couldn't be executed because of the limited cache. If the user didn't change any of the two and is using the defaults, log a warning but don't prevent the node from starting up.
2023-02-16validation: return VerifyDBResult::INTERRUPTED if verification was interruptedMartin Zumsande
This means that the -verifydb RPC will now return false if it cannot finish due to the node being shutdown.

This does not change behavior. It is in preparation for special handling of the case where VerifyDB doesn't finish for various reasons, but doesn't fail.

2023-02-10refactor, txdb: Add CoinsViewOptions structRyan Ofsky
Add CoinsViewOptions struct to remove ArgsManager uses from txdb. To reduce size of this commit, this moves references to gArgs variable out of txdb.cpp to calling code in validation.cpp. But these moves are temporary. The gArgs references in validation.cpp are moved out to calling code in init.cpp in later commits. This commit does not change behavior.

2023-01-31validation: Skip VerifyDB checks of level >=3 if dbcache is too smallMartin Zumsande
The previous behavior, skipping some L3 DisconnectBlock calls, but still attempting to reconnect these blocks at L4, makes ConnectBlock assert. The variable skipped_l3_checks is introduced because even with an insufficient cache for the L3 checks, the L1/L2 checks in the same loop should still be completed. Fixes #25563.

2023-01-10[validation] return MempoolAcceptResult for every tx on PCKG_TX failureglozow
This makes the interface more predictable and useful. The caller understands one or more transactions failed, and can learn what happened with each transaction. We already have this information, so we might as well return it. It doesn't make sense to do this for other PackageValidationResult values because: - PCKG_RESULT_UNSET: this means everything succeeded, so the individual failures are no longer accurate. - PCKG_MEMPOOL_ERROR: something went wrong with the mempool logic; transaction failures might not be meaningful. - PCKG_POLICY: this means something was wrong with the package as a whole. The caller should use the PackageValidationState to find the error, rather than looking at individual MempoolAcceptResults.

This PR fixes this unexpected behaviour and introduces refactoring improvements to make intents and effects of the code more clear. ## Unexpected behaviour This behaviour occurs only in the package acceptance path, currently only triggered by `testmempoolaccept` and `submitpackage` RPCs. In `MemPoolAccept::AcceptMultipleTransactions()`, we first call `PreChecks()` and then `SubmitPackage()` with the same `Workspace ws` reference. `PreChecks` leaves `ws.m_ancestors` in a potentially non-empty state, before it is passed on to `MemPoolAccept::SubmitPackage`. `SubmitPackage` is the only place where `setAncestors` isn't guaranteed to be empty before calling `CalculateMemPoolAncestors`. The most straightforward fix is to just forcefully clear `setAncestors` at the beginning of CalculateMemPoolAncestors, which is done in the first bugfix commit. ## Improvements ### Return value instead of out-parameters This PR updates the function signatures for `CTxMemPool::CalculateMemPoolAncestors` and `CTxMemPool::CalculateAncestorsAndCheckLimits` to use a `util::Result` return type and eliminate both the `setAncestors` `in,out`-parameter as well as the error string. It simplifies the code and makes the intent and effects more explicit. ### Observability There are 7 instances where we currently call `CalculateMemPoolAncestors` without actually checking if the function succeeded because we assume that it can't fail, such as in [miner.cpp](https://github.com/bitcoin/bitcoin/blob/69b10212ea5370606c7a5aa500a70c36b4cbb58f/src/node/miner.cpp#L399). This PR adds a new wrapper `AssumeCalculateMemPoolAncestors` function that logs such unexpected failures, or in case of debug builds even halts the program. It's not crucial to the objective, more of an observability improvement that seems sensible to add on here.

There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical. Two changes could be accomplished: 1) Anything not 64 bytes could be allowed 2) Anything above 64 bytes could be allowed In the Great Consensus Cleanup, suggestion (2) was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5. The functional test is also modified to test the actual case we care about: 64 bytes Related mailing list discussions here: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-October/020995.html And a couple years earlier: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2020-May/017883.html ACKs for top commit: achow101: reACK b2aa9e85289fc654106a890c35935e9c76c411fb glozow: reACK b2aa9e85289fc654106a890c35935e9c76c411fb pablomartin4btc: re-ACK https://github.com/bitcoin/bitcoin/commit/b2aa9e85289fc654106a890c35935e9c76c411fb jonatack: ACK b2aa9e85289fc654106a890c35935e9c76c411fb with some suggestions Tree-SHA512: c1ec1af9ddcf31b2272209a4f1ee0c5607399f8172e5a1dfd4604cf98bfb933810dd9369a5917ad122add003327c9fcf6ee26995de3aca41d5c42dba527991ad
