7031721f2cc3eef30c46ff50c52328e9ba8090e0 rpc/listaddressgroupings: redefine inner-most array as ARR_FIXED (Karl-Johan Alm)
8500f7bf54d3e27fd2fa7fda15ad833f5688c331 rpc/createrawtransaction: redefine addresses as OBJ_USER_KEYS (Karl-Johan Alm)
d9e2183c50f50465b9f173171fee240949bf8bd2 rpc: include OBJ_USER_KEY in RPCArg constructor checks (Karl-Johan Alm)
Pull request description:
This PR adjusts the two issues I encountered while developing a tool that converts RPCHelpMan objects into bindings for other language(s).
The first is in createrawtransaction, where the address part, e.g. bc1qabc in
> createrawtransaction '[]' '[{"bc1qabc": 1.0}]'
is declared as a `Type::OBJ`, when in reality it should be a `Type::OBJ_USER_KEYS`, defined as such:
https://github.com/bitcoin/bitcoin/blob/5925f1e652768a9502831b9ccf78d16cf3c37d29/src/rpc/util.h#L126
(coincidentally, this is the first and only (afaict) usage of this `RPCArg::Type`).
The second is in the `listaddressgroupings` RPC, which returns an array of arrays of arrays, where the innermost one is a tuple-thingie with an optional 3rd item; this is an `ARR_FIXED`, not an `ARR`.

fa2204f6adef493079d1ca5148b0fdc2b55816e6 streams: Accept URef obj for VectorReader unserialize (MarcoFalke)
Pull request description:
Missed in commit 172f5fa738d419efda99542e2ad2a0f4db5be580. An URef may collapse into an LRef or RRef depending on context. There is no reason to forbid RRef in `VectorReader::operator>>`, so add it for consistency.

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.
Can be reviewed with --ignore-all-space --color-moved=dimmed-zebra

This test can now be run even with the Bitcoin Core wallet disabled.

ARR_FIXED is for cases like this, where the elements are in an array for convenience, rather than due to being dynamically sized lists.
|
|
The OBJ type is for actual objects with defined keys; OBJ_USER_KEYS is for objects with user-defined keys (such as the bitcoin address(es) in the createrawtransaction output object.

The LLVM Clang we use for cross-compilation supports this option, and it's expected
that any builders on macOS will also be using an Apple Clang that supports it.

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.

linter test
2227fc4e6203064b14e99bcf453601bd263a0196 test: minor fixes & improvements for files linter test (windsok)
Pull request description:
Couple of minor fixes & improvements for files linter test added in #21740
- Use a context manager when opening files, so that files are closed are we are done with them
- Use the `-z` flag when shelling out to `git ls-files` so that we can catch newlines and other weird control characters in filenames.
From the `git ls-files` manpage:
```
-z \0 line termination on output and do not quote filenames. See OUTPUT below for more information.
Without the -z option, pathnames with "unusual" characters are quoted as explained for the configuration variable
core.quotePath (see git-config(1)). Using -z the filename is output verbatim and the line is terminated by a NUL byte.

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(...)`.

fabb6dfe6e734eadd91448122f2ce8c1612c39a6 script: Replace address-of idiom with vector data() method (Guido Vranken)
Pull request description:
The main theme of this refactor is to replace `&foo[0]` with `foo.data()`.
The first commit is taken from #21781 with the rationale:
* In CSignatureCache::ComputeEntryECDSA, change the way a vector pointer is resolved to prevent invoking undefined behavior if the vector is empty.
The other commits aim to remove all `&foo[0]`, where `foo` is any kind of byte representation. The rationale:
* Sometimes alternative code without any raw data pointers is easier to read (refer to the respective commit message for details)
* If the raw data pointer is needed, `foo.data()` should be preferred, as pointed out in the developer notes. This addresses the instances that have been missed in commit 592404f03f2b734351d734f0c9ca1fdce997321b, and https://github.com/bitcoin/bitcoin/pull/9804

46b025e00df40724175735eb5606ac73067cb3b8 test: add new python linter to check file names and permissions (windsok)
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.
Fixes #21729

2896c6c4cc6d382d8369c037e274c08dd8e32c69 doc: update addnode rpc help (Jon Atack)
Pull request description:
Since #9319 proposed by Gregory Maxwell and released in v0.14, peers manually added through the `-addnode` config option or using the `addnode` RPC have their own separate limit of 8 connections that does not compete with other inbound or outbound connection usage and is not subject to the limitation imposed by the `-maxconnections` option.
This PR updates the `-addnode` and `-maxconnections` config options and the `addnode` RPC help docs with this information.
`-addnode` config option help
```
$ bitcoind -h | grep -A5 addnode=
-addnode=<ip>
Add a node to connect to and attempt to keep the connection open (see
the addnode RPC help for more info). This option can be specified
multiple times to add multiple nodes; connections are limited to
8 at a time and are counted separately from the -maxconnections
limit.
$ bitcoind -h | grep -A3 maxconnections=
-maxconnections=<n>
Maintain at most <n> connections to peers (default: 125). This limit
does not apply to connections manually added via -addnode or the
addnode RPC, which have a separate limit of 8.
```
`addnode` rpc help
```
$ bitcoin-cli help addnode
addnode "node" "command"
Attempts to add or remove a node from the addnode list.
Or try a connection to a node once.
Nodes added using addnode (or -connect) are protected from DoS disconnection and are not required to be
full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).
Addnode connections are limited to 8 at a time and are counted separately from the -maxconnections limit.
