4bea30169218e2f21e0c93a059966b41c8edd205 test: use P2PK-MiniWallet for feature_csv_activation.py (Sebastian Falbesoner)
dc7eb64e83f5b8e63f12729d5f77b1c920b136e4 test: MiniWallet: add P2PK support (Sebastian Falbesoner)
Pull request description:
This PR adds support for creating and spending transactions with raw pubkey (P2PK) outputs to MiniWallet, [as suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/21900#discussion_r629524841). Using that mode in the test `feature_csv_activation.py`, all txs submitted to the mempool follow the standard policy, i.e. `-acceptnonstdtxn=1` can be removed.
Possible follow-ups:
* Improve MiniWallet constructor Interface; an enum-like parameter instead of two booleans would probably be better
* Look at other tests that could benefit from P2PK (e.g. feature_cltv.py?)
* Check vsize also for P2PK txs (vsize varies due to signature, i.e. a range has to be asserted)

Remove the erroneous trailing newline '\n'. Also, print only the first
value to remove needless redundancy in the error message.
|
|
|
|
|
|
Using the MiniWallet in P2PK mode, all transactions submitted to the
mempool are following the standard policy now, i.e. the node command
line parameter '-acceptnonstdtxn=1' is not needed anymore.

bd7f27d16dacf6f7de3b4f6bd052def41d9601be refactor: feature_csv_activation.py: move tx helper functions to methods (Sebastian Falbesoner)
2eca46b0aa0ecf4738500b53523d7013985b387d test: use MiniWallet for feature_csv_activation.py (Sebastian Falbesoner)
Pull request description:
This PR enables one more of the non-wallet functional tests (feature_csv_activation.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078.
Short reviewers guideline:
- Since we exclusively work with anyone-can-spend outputs here (raw scriptPubKey = OP_TRUE), signing is not needed anymore. The function `sign_transaction` and its calls are removed, after changing a tx (e.g. its scriptSig or nVersion) a simple `.rehash()` call is sufficient. Also, generating an address `self.nodeaddress` (and with that, passing it to the the various test tx creation/sending helper methods) is not needed anymore and removed.
- The test repeatedly uses the same input for creating different txs (e.g. with different txversions 1 and 2). To let `MiniWallet` create a tx with a specific input, we have to call `.get_utxo()` before which also marks the UTXO as spent. The method is changed to also support keeping the UTXO in its internal list (`mark_as_spent=False`). With the behaviour on master, the second call to `.get_utxo()` with the same input would fail.
- To keep the diff in the first commit short, the `miniwallet` is set as a global variable, to avoid passing it on every tx creation/spending helper. The global is eliminated in the second (refactoring) commit, where all the helpers are moved to the test class as methods. By that, we can use `self.nodes[0]` directly in the helpers and don't have to pass it again and again. I think there could still be a lot of improvements/refactoring done in the test, but that should hopefully serve as a good basis.

11d6459b6e101f05f36e13799c400bef82d2fc21 rpc: include_unsafe option for fundrawtransaction (t-bast)
Pull request description:

I also added this option to `send` and `walletcreatefundedpsbt` who internally delegate to `fundrawtransaction`.

This allows to get rid of the global miniwallet variable and to specify
the used node self.nodes[0] at only one place, instead of passing it to
every tx creation/send method again and again.

955eee76803c098978cf0bbc7f1f6d3c230544e2 net: Sanitize message type for logging (W. J. van der Laan)
Pull request description:
- Use `SanitizeString` when logging message errors to make sure that the message type is sanitized. I have checked all logging in `net.cpp`.
- For the `MESSAGESTART` error don't inspect and log header details at all: receiving invalid start bytes makes it likely that the packet isn't even formatted as valid P2P message. Logging the four unexpected start bytes (as hex) should be enough.
- Update `p2p_invalid_messages.py` test to check this.
- Improve error messages in a second commit.
Issue reported by gmaxwell.

9f767e84381d678ed24e3f7f981976f9da34971e test: use MiniWallet for p2p_blocksonly.py (Sebastian Falbesoner)
Pull request description:
This PR enables one more of the non-wallet functional tests (p2p_blocksonly.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078.
Note that MiniWallet creates segwit transactions by default, i.e. txid and wtxid are not identical and we have to return both from `check_p2p_tx_violation(...)`: wtxid is needed to match an expected `"received getdata for: wtx ..."` debug output, whereas the txid is needed to wait for a certain tx via `wait_for_tx(...)`.

hardcoded nChainTx

931684b24a89aba884cb18c13fa67ccca339ee8c validation: fix ActivateSnapshot to use hardcoded nChainTx (James O'Beirne)
Pull request description:
This fixes an oversight from the move of nChainTx from the user-supplied
snapshot metadata into the hardcoded assumeutxo chainparams.
Since the nChainTx is now unused in the metadata, it should be removed
in a future commit.

6f6bb3ebc7cb8e17a5dfc8ef55aa2d3f2dc6bdea test: fix file permissions on various scripts (windsok)
Pull request description:
Adds a new python linter test which tests for correct filenames and file permissions in the repository.
Replaces the existing tests in the `test/lint/lint-filenames.sh` and `test/lint/lint-shebang.sh` linter tests, as well as adding some new and increased testing. This increased coverage is intended to catch issues such as in #21728 and https://github.com/bitcoin/bitcoin/pull/16807/files#r345547050
Summary of tests:
* Checks every file in the repository against an allowed regexp to make sure only lowercase or uppercase alphanumerics (a-zA-Z0-9), underscores (_), hyphens (-), at (@) and dots (.) are used in repository filenames.
* Checks only source files (*.cpp, *.h, *.py, *.sh) against a stricter allowed regexp to make sure only lowercase alphanumerics (a-z0-9), underscores (_), hyphens (-) and dots (.) are used in source code filenames. Additionally there is an exception regexp for directories or files which are excepted from matching this regexp (This should replicate the existing `test/lint/lint-filenames.sh` test)
* Checks all files in the repository match an allowed executable or non-executable file permission octal. Additionally checks that for executable files, the file contains a shebang line.
* Checks that for executable `.py` and `.sh` files, the shebang line used matches an allowable list of shebangs (This should replicate the existing `test/lint/lint-shebang.sh` test)
* Checks every file that contains a shebang line to ensure it has an executable permission
Additionally updates the permissions on various files to comply with the new tests.

As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step.
Features summary:
- Users can start their node with the option `-coinstatsindex` which syncs the index in the background
- After the index is synced the user can use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index
- The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

d831e711cab83c70bf2ded62fe33f484844e73dd [validation] RewindBlockIndex no longer needed (Dhruv Mehta)
Pull request description:
Closes #17862
Context from [original comment](https://github.com/bitcoin/bitcoin/issues/17862#issuecomment-744285188) (minor edits):
`RewindBlockIndex()` is a mechanism to allow nodes to be upgraded after segwit activation, while still keeping their chainstate/datadir in a consistent state. It works as follows:
- A pre-segwit (i.e. v0.13.0 or older) node is running.
- Segwit activates. The pre-segwit node remains sync'ed to the tip, but is not enforcing the new segwit rules.
- The user upgrades the node to a segwit-aware version (v0.13.1 or newer).
- On startup, in `AppInitMain()`, `RewindBlockIndex()` is called. This walks the chain backwards from the tip, disconnecting and erasing blocks that from after segwit activation that weren't validated with segwit rules.
- those blocks are then redownloaded (with witness data) and validated with segwit rules.
This logic probably isn't required any more since:
- Segwit activated at height 481824, when the block chain was 130GB and the total number of txs was 250 million. Today, we're at height 667704, the blockchain is over 315GB and the total number of txs is over 600 million. Even if 20% of that added data is witness data (a high estimate), then around 150GB of transactions would need to be rewound to get back to segwit activation height. It'd probably be faster to simply validate from genesis, especially since we won't be validating any scripts before the assumevalid block. It's also unclear whether rewinding 150GB of transactions would even work. It's certainly never been tested.
- Bitcoin Core v0.13 is hardly used any more. https://luke.dashjr.org/programs/bitcoin/files/charts/software.html shows less than 50 nodes running it. The software was EOL on Aug 1st 2018. It's very unlikely that anyone is running 0.13 and will want to upgrade to 0.22.
This PR introduces `NeedsRedownload()` which merely checks for insufficiently validated segwit blocks and requests that the user restarts the node with `-reindex`. Reindexing the block files upon restart will make the node rebuild chain state and block index from the `blk*.dat` files on disk. The node won't be able to index the blocks with `BLOCK_OPT_WITNESS`, so they will be missing from the chain and be re-downloaded, with witness data.
Removing this code allows the following (done in follow-up #21090):
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

This value is no longer used and is instead specified statically
in chainparams. This change means that previously generated
snapshots will no longer be usable.
