fae71d30f7 clang-tidy: Apply modernize-deprecated-headers (MarcoFalke)

Pull request description:

  Bitcoin Core is written in C++, so it is confusing to sometimes use the deprecated C headers (with the `.h` extension). For example, it is less clear whether `string.h` refers to the file in this repo or the cstring stdlib header (https://github.com/bitcoin/bitcoin/pull/31308#discussion_r2121492797).

  The check is currently disabled for headers, to exclude subtree headers.

Pull request description:

  Retains the `-datacarrier*` args, marks them as deprecated, and does not require another startup argument for multiple OP_RETURN outputs.

  If a user has set `-datacarriersize` the value is "budgeted" across all seen OP_RETURN output scriptPubKeys. In other words the total script bytes stays the same, but can be spread across any number of outputs. This is done to not introduce an additional argument to support multiple outputs.

  I do not advise people use the option with custom arguments and it is marked as deprecated to not mislead as a promise to offer it forever. The argument itself can be removed in some future release to clean up the code and minimize footguns for users.

12ff4be9c7 test: ensure -rpcallowip is compatible with RFC4193 (Matthew Zipkin)
c02bd3c187 config: Explain RFC4193 and CJDNS interaction in help and init error (Matthew Zipkin)
f728b6b111 init: Configure reachable networks before we start the RPC server (Matthew Zipkin)

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/32433

  `MaybeFlipIPv6toCJDNS()` relies on `g_reachable_nets` to distinguish between CJDNS addresses and other IPv6 addresses. In particular, [RFC4193](https://www.rfc-editor.org/rfc/rfc4193#section-3.1) address or "Unique Local Address" with the L-bit unset also begins with the `fc` prefix. #32433 highlights a use case for these addresses that have nothing to do with CJDNS.

  On master we don't parse init flags like `-cjdnsreachable` until *after* the HTTP server has started, causing conflicts with `-rpcallowip` because CJDNS doesn't support subnets.

  This PR ensures that `NET_CJDNS` is only present in the reachable networks list if set by `-cjdnsreachable` *before* `-rpcallowip` is checked. If it is set all `fc` addresses are assumed to be CJDNS, can not have subnets, and can't be set for `-rpcallowip`.

  I also noted this specific parameter interaction in the init help as well as the error message if configured incorrectly.

  This can be tested locally:

  `bitcoind -regtest -rpcallowip=fc00:dead:beef::/64 -rpcuser=u -rpcpassword=p`

  On master this will just throw an error that doesn't even mention IPv6 at all.

  On the branch, this will succeed and can be tested by adding the ULA to a local interface.

  On linux: `sudo ip -6 addr add fc00:dead:beef::1/64 dev lo`

  On macos: `sudo ifconfig lo0 inet6 fc00:dead:beef::1/128 add`

  then: `curl -v -g -6 --interface fc00:dead:beef::1 u:p@[::1]:18443 --data '{"method":"getblockcount"}'`

  If the `rpcallowip` option is removed, the RPC request will fail to authorize.

  Finally, adding `-cjdnsreachable` to the start up command will throw an error and specify the incompatibility:

  > RFC4193 is allowed only if -cjdnsreachable=0.

0b4048c733 datacarrier: deprecate startup arguments for future removal 2025-05-30 10:14:18 -04:00
Greg Sanders
9f36962b07 policy: uncap datacarrier by default
Datacarrier output script sizes and output counts are now
uncapped by default.

To avoid introducing another startup argument, we modify the
OP_RETURN accounting to "budget" the spk sizes.

If a user has set a custom default, this results in that
budget being spent over the sum of all OP_RETURN outputs'
scripts in the transaction, no longer capping the number
of OP_RETURN outputs themselves. This should allow a
superset of current behavior while respecting the passed
argument in terms of total arbitrary data storage.

Pull request description:

  The legacy int parsing is problematic, because it accepts the `+` sign for unsigned integers. In all cases this is either:

  * Useless, because the `+` sign was already rejected.
  * Erroneous and inconsistent, when third party parsers reject it. (C.f. https://github.com/bitcoin/bitcoin/pull/32365)
  * Confusing, because the `+` sign is  neither documented, nor can it be assumed to be present.

  Fix all issues by removing the legacy int parsing.

fa2b529f92 refactor: Remove redundant call to IsArgSet
Checking for IsArgSet before calling GetArg while providing an arbitrary
default value as fallback is both confusing and fragile.

It is confusing, because the provided fallback is dead code. So it would
be better to just call GetArg without a fallback.

Even better would be to provide the true fallback value and sanitize it
as if it were user-input, but this can be done in a follow-up.

Removing the redundant call to IsArgSet will have to be done either way,
so do it now.

44041ae0ec init: Handle dropped UPnP support more gracefully
Closes bitcoin-core/gui#843.

In that issue it was brought up that users likely don't care what kind
of port forwarding is used, and the setting is opportunistic anyway, so
instead of showing an extensive warning, we can simply migrate from
UPNP to NAT-PMP+PCP. This prevents nodes dropping from the public
network.

- Change the logic for removed runtime setting `-upnp` to set `-natpmp`
  instead, and only log a message.

- Also replace any lingering `upnp` in `settings.json` with `natpmp`.

Treat specifying -noexternalip the same as not specifying -externalip, instead
of causing it to soft-set the -discover default to false.

Before this change, was -noexternalip basically an undocumented synonym for
-nodiscover.

After this change, specifying -noexternalip just clears previously specifed
-externalip options, restoring default behavior as if they were not were
specified.

The previous -noexternalip behavior wasn't neccessarily bad, but it was
undocumented, redundant with the -nodiscover option, and inconsistent with
behavior of other list options.

ecd590d4c1 Normalize inconsistent -noonlynet behavior
Treat specifying -noonlynet the same as not specifying -onlynet, instead of
marking all networks unreachable.

Before this change, specifying -noonlynet cleared list of reachable networks
and did not allow connecting to any network. It was basically an undocumented
synonym for -noconnect.

After this change, specifying -nononlynet just clears previously specifed
-onlynet options and allows connecting to all networks, restoring default
behavior as if no -onlynet options were specified.

Before this change, there was no way to restore default behavior once an
-onlynet option was specified. So for example, if a config file specifed
onlynet settings, they couldn't be reset on the command line without disabling
the entire config file.

The previous -noonlynet behavior wasn't neccessarily bad, but it was
undocumented, redundant with the -noconnect option, inconsistent with behavior
of other list options, and inconsistent with being able to use the command line
to selectively override config options. It was also probably unintended,
arising from use of the IsArgSet() method and its interaction with negated
options.

Pull request description:

  * This PR attempts to fix the duplicate coinbase weight reservation issue we currently have.
  * Fixes #21950

  We reserve 4000 weight units for coinbase transaction in `DEFAULT_BLOCK_MAX_WEIGHT`

  7590e93bc7/src/policy/policy.h (L23)

  And also reserve additional `4000` weight units in the default `BlockCreationOptions` struct.

  7590e93bc7/src/node/types.h (L36-L40)

  **Motivation**

  - This issue was first noticed during a review here https://github.com/bitcoin/bitcoin/pull/11100#discussion_r136157411)
  - It was later reported in issue #21950.
  - I also came across the bug while writing a test for building the block template. I could not create a block template above `3,992,000` in the block assembler, and this was not documented anywhere. It took me a while to realize that we were reserving space for the coinbase transaction weight twice.

  ---
  This PR fixes this by consolidating the reservation to be in a single location in the codebase.

  This PR then adds a new startup option `-blockreservedweight` whose default is `8000` that can be used to lower or increase the block reserved weight for block header, txs count, coinbase tx.

  The change was initially motivated to make it easier for users of the kernel library to instantiate a BlockManager that may be used to read data from disk without loading the block index into a cache.

Pull request description:

  This probably should've been included in #12653 when `-blocksdir` was introduced. Credit TheCharlatan for noticing that it's missing.

  This guards against 2 processes running with separate datadirs but the same blocksdir. I didn't add `walletdir` as I assume sqlite has us covered there.

  It's not likely to happen currently, but may be more relevant in the future with applications using the kernel. Note that the kernel does not currently do any dir locking, but it should.

Pull request description:

  `UndoWriteToDisk` and `WriteBlockToDisk` were delegating a subset of their functionality to single-use methods that didn't optimally capture a meaningful chunk of the algorithm, resulting in calculating things twice (serialized size, header size).
  This change inlines the awkward methods (asserting that all previous behavior was retained), and in separate commits makes the usages less confusing.
  Besides making the methods slightly more intuitive, the refactorings reduce duplicate calculations as well.

  The speed difference is insignificant for now (~0.5% for the new `SaveBlockToDiskBench`), but are a cleanup for follow-ups such as https://github.com/bitcoin/bitcoin/pull/31539

0cdddeb224 kernel: Move block tree db open to BlockManager constructor
Make the block db open RAII style by calling it in the BlockManager
constructor.

Before this change the block tree db was needlessly re-opened during
startup when loading a completed snapshot. Improve this by letting the
block manager open it on construction. This also simplifies the test
code a bit.

The change was initially motivated to make it easier for users of the
kernel library to instantiate a BlockManager that may be used to read
data from disk without loading the block index into a cache.

7fbb1bc44b kernel: Move block tree db open to block manager
This commit is done in preparation for the next commit. Here, the block
tree options are moved to the blockmanager options and the block tree is
instantiated through a helper method of the BlockManager, which is
removed again in the next commit.

Pull request description:

  Carrying non-kernel related fields in the cache sizes for the indexes is confusing for kernel library users. The cache sizes are set currently with magic numbers in bitcoin-chainstate. The comments for the cache size calculations are not completely clear. The constants for the cache sizes are also currently in `txdb.h`, which is not an ideal place for holding all cache size related constants.

  Solve these things by moving the kernel-specific cache size fields to their own struct and moving the constants to either the node or the kernel cache sizes.

  This slightly changes the way the cache is allocated if (and only if) the txindex and/or blockfilterindex is used. Since they are now given precedence over the block tree db cache, this results in a bit less cache being allocated to the block tree db, coinsdb and coins caches. The effect is negligible though, i.e. cache sizes with default dbcache reported through the logs are:

  master:
  ```
  Cache configuration:
  * Using 2.0 MiB for block index database
  * Using 56.0 MiB for transaction index database
  * Using 49.0 MiB for basic block filter index database
  * Using 8.0 MiB for chain state database
  * Using 335.0 MiB for in-memory UTXO set (plus up to 286.1 MiB of unused mempool space)
  ```

2a92702baf init: Use size_t consistently for cache sizes
This avoids having to rely on implicit casts when passing them to the
various functions allocating the caches.

This also ensures that if the requested amount of db_cache does not fit
in a size_t, it is clamped to the maximum value of a size_t.

Also take this opportunity to make the total amounts of cache in the
chainstate manager a size_t too.
