create a script for parsing the output from `bitcoind --help` to create an example conf file for new users
## problem
per #10746 , `bitcoin.conf` not being put into the data directory during installation causes some confusion for users when running bitcoin. in the discussion on the issue, one proposed solution was to have an example config file and instruct users to `cp` it into their data directory after startup. in addition to #10746 , there have been other requests for a "skeleton config file" (https://github.com/bitcoin/bitcoin/issues/19641) to help users get started with configuring bitcoind.
the main issue with an example config file is that it creates a second source of truth regarding what options are available for configuring bitcoind. this means any changes to the options (including the addition or removal of options) would have to be updated for the command line and also updated in the example file.
this PR addresses this issue by providing a script to generate an example file directly from the `bitcoind --help` on-demand by running `contrib/devtools/gen-bitcoin-conf.sh`. this solution was originally proposed on #10746 and would also solve #19641 . this guarantees any changes made to the command-line options or the command-line options help would also be reflected in the example file after compiling and running the script.
the main purpose of this script is to generate a config file to be included with releases, same as `gen-manpages.sh`. this ensures every release also includes an up-to-date, full example config file for users to edit. the script is also available for users who compile from source for generating an example config for their compiled binary.
## special considerations
this removes the `bitcoin.conf` example file from the repo as it is now generated by this script. the original example file did contain extra text related to how to use certain options but going forward all option help docs should be moved into `init.cpp`
this also edits `init.cpp` to have the option help indicate that `-conf` is not usable from the config file. this is similar to how `-includeconf` 's help indicates it cannot be used from the command line

Fixes https://github.com/bitcoin/bitcoin/issues/22964
Previously, we used UnloadBlockIndex() in order to reset node.mempool
and node.chainman. However, that has proven to be fragile (see
https://github.com/bitcoin/bitcoin/issues/22964), and requires
UnloadBlockIndex and its callees to be updated manually for each member
that's introduced to the mempool and chainman classes.
In this commit, we stop using the UnloadBlockIndex function and we
simply reconstruct node.mempool and node.chainman.
Since PeerManager needs a valid reference to both node.mempool and
node.chainman, we also move PeerManager's construction via `::make` to
after the chainstate activation sequence is complete.
There are no more callers to UnloadBlockIndex after this commit, so it
and its sole callees can be pruned.

# Motivation
The main motivation of this change and only behavior change noticeable by user is to allow running `coinstatsindex` on pruned nodes as has been requested [here for example](https://twitter.com/benthecarman/status/1388170854140452870?s=20).
# Background
`coinstatsindex` on pruned nodes can be enabled in a much simpler than it is done here but it comes with downside. The ability to run `blockfilterindex`on pruned nodes was added in #15946 but it also added the `blockfilterindex` as a dependency to `validation` and it introduced two new circular dependencies. Enabling `coinstatsindex` on pruned nodes in a similar way would add it as a dependency as well and introduce another circular dependency.
Instead, this PR introduces a `m_prune_blockers` map to `BlockManager` as a flexible approach to block pruning. Entities like `blockfilterindex`, for example, can add a key and a height to block pruning over that height. These entities need to update that value to allow more pruning when they are ready.
# Alternative approach
Upon completing the first draft of this PR I found #19463 as an alternative that follows the same but follows a very different approach. I am listing the main differences here as I see them:
- Usage of globals
- Blocks pruning with a start and a stop height
- Can persist blockers across restarts
- Blockers can be set/unset via RPCs
Personally, I don't think any of these are necessary to be added here but if the general approach or specific features are more appealing to reviewers I am happy to change to a solution based on that PR or port over specific parts of it here.

This drops the `No proxy server specified. Use -proxy=<ip> or -proxy=<ip:port>`
error when a empty `-proxy=` command line argument, `bitcoin.conf` value, or
`settings.json` value is specified, and just makes bitcoin connect and listen
normally in these cases.
The error was originally added in https://github.com/bitcoin/bitcoin/pull/20003
to prevent a bare `-proxy` command line argument with no assignment from
clearing proxy settings. But it was implemented in an overbroad way breaking
empty `-proxy=` assignments as well.
The motivation for this change is to prevent a GUI bug that happens with
https://github.com/bitcoin/bitcoin/pull/15936, reported in
https://github.com/bitcoin/bitcoin/pull/15936#pullrequestreview-937685759 by
vasild, that happens after a proxy setting is enabled and disabled in the GUI.
But this change also makes sense on its own to remove a potentially confusing
error message.
dac44fc06f init: disallow reindex-chainstate with optional indexes (Martin Zumsande)
62e14285f9 doc: Add note that -reindex will rebuild optional indexes (Martin Zumsande)
Pull request description:
When started together with `-reindex-chainstate`, currently coinstatsindex gets corrupted and the blockfilterindex flatfiles duplicated. See the OP of #24630 for more a more detailed explanation on why this happens.
This is an alternative to #24630 which does not wipe and rebuild the indexes but returns an `InitError` when they are activated, thus requiring the user to deactivate them temporarily until the `-reindex-chainstate` run is finished.
This also disallows `-reindex-chainstate` in combination with `-txindex`, which is not leading to corruption, but currently still rebuilds the index unnecessarily and unexpectedly.
As a long-term goal, it would be desirable to have the indexes tolerate `reindex-chainstate` by ignoring their `BlockConnected` notifications (there is discussion in #24630 about this) or possibly move `reindex-chainstate` option into a `bitcoin-chainstate` executable, which could also solve the problem. But these would be larger projects - until then, it might be better to disallow the interaction than having corrupted indexes.
The first commit adjusts the `-reindex` doc to mention that this option does rebuild all active indexes.

Pull request description:
The asmap data is currently owned by addrman, but is used by both addrman and connman. #22791 made the data const and private (so that it can't be updated by other components), but it is still passed out of addrman as a reference to const, and used by `CNetAddress` to calculate the group and AS of the net address.
This RFC PR proposes to move all asmap data and logic into a new `NetGroupManager` component. This is initialized at startup, and the client components addrman and connman simply call `NetGroupManager::GetGroup(const CAddress&)` and `NetGroupManager::GetMappedAS(const CAddress&)` to get the net group and AS of an address.

Pull request description:
It is not possible to upgrade Bitcoin Core pre-segwit (pre-0.13.1) to a recent version without a full IBD from scratch after commit 19a56d1519 (released in version 22.0).
Any Bitcoin Core version with the new database format after commit 1088b02f0c (released in version 0.15), can upgrade to any version that is supported as of today.
This leaves the versions 0.13.1-0.14.x. Even though those versions are unsupported, some users with an existing datadir may want to upgrade to a recent version. However, it seems reasonable to simply ask them to `-reindex` to run a full IBD from scratch. This allows us to remove the utxo db upgrade code.

- Add `GetPathArg` default argument so it is less awkward to use to parse options that have default values.
- Fix `GetPathArg` negated argument handling. Return path{} not path{"0"} when path argument is negated.
- Add unit tests for default and negated cases
- Move `GetPathArg` method declaration next to `GetArg` declaration. The two methods are close substitutes for each, so this should help keep them consistent and make them more discoverable.

has a strong preference for only connecting to nodes that listen on that

Remove that preference because connections over clearnet that involve
port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p
traffic before the connection is even established (at TCP SYN time).

6981de4435 doc: fix wording of alertnotify (willcl-ark)
Pull request description:
The documentation of the `alertnotify` startup option no longer matches the implementation.
Currently the alert is only triggered by `DoWarning` (as part of `CChainstate::UpdateTip` when blocks containing unknown versionbits are detected on the network, indicating that there may be an upcoming softfork which you don't know about), but not when we see a "really long fork":
2825c41a61/src/validation.cpp (L2418-L2433)
I think it would be desirable in a follow-up PR to implement the logic to alert on a (really) long fork, but not to alert for "partition detection" (abnormally slow/fast blocks). `PartitionChecker` code was removed in ab8be98fdb

By default, for mainnet, the p2p listening port is 8333. Bitcoin Core
has a strong preference for only connecting to nodes that listen on that
port.
Remove that preference because connections over clearnet that involve
port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p
traffic before the connection is even established (at TCP SYN time).
For further justification see the OP of:

Pull request description:
There are 2 proposed fixups in discussions in #23280 which I have not implemented:
1. An overhaul to return types and an option type for the two `*Chainstate` functions: https://github.com/bitcoin/bitcoin/pull/23280#issuecomment-984149564
- The change reintroduces stringy return types and is quite involved. It could be discussed in a separate PR.
2. Passing in the unix time to `VerifyChainstate` instead of a callback to get the time: https://github.com/bitcoin/bitcoin/pull/23280#discussion_r765051533
- I'm not sure it matters much whether it's a callback or just the actual unix time. Also, I think `VerifyDB` can take quite a while, and I don't want to impose that the function have to "run quickly" in order to have it be correct.
If reviewers feel strongly about either of the two fixups listed above, please feel free to open a PR based on mine and I'll close this one!

...by moving the try/catch out of LoadChainstate
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
...instead allow the caller to optionally pass in callbacks which are
triggered for certain events.
Behaviour change: The string "Verifying blocks..." was previously
printed for each chainstate in chainman which did not have an
effectively empty coinsview, now it will be printed once unconditionally
before we call VerifyLoadedChain.
This allows us to separate the initialization code from translations and
error reporting.
This change changes the caller semantics of LoadChainstate quite
drastically.
To see that this change doesn't change behaviour, observe that:
1. Prior to this change, LoadChainstate returned false only in the "bad
genesis block" failure case (by returning InitError()), indicating
that the caller should immediately bail. After this change, the
corresponding ERROR_BAD_GENESIS_BLOCK handler in src/init.cpp
maintains behavioue by also bailing immediately.
2. The failed_* temporary booleans were only used to break out of the
outer do/while(false) loop. They can therefore be safely removed.
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
[META] This commit is intended to be as close to a move-only commit as
possible, and lingering ugliness will be resolved in subsequent
commits.
A few variables that are passed in by value instead of by reference
deserve explanation:
- fReset and fReindexChainstate are both local variables in AppInitMain
and are not modified in the sequence
- fPruneMode, despite being a global, is only modified in
AppInitParameterInteraction, long before LoadChainstate is called

ad085f9ba1 multiprocess: Delay wallet client construction (Russell Yanofsky)
Pull request description:
Delay wallet client construction until after logging, thread and other init for two reasons:
- More responsive multiprocess GUI startup. When bitcoin-gui is started this moves the call from bitcoin-gui to bitcoin-node that spawns bitcoin-wallet off of the GUI event thread and onto the background GUI init executor thread.
- Avoids feature_logging.py test failures with bitcoin-node by making bitcoin-wallet logging start after bitcoin-node logging starts,
because the tests are not written to handle the bitcoin-wallet logging init code running first.
This partially reverts commit b266b3e0bf, moving wallet client creation back to the place it was located before.

CJDNS is set up in the host OS, outside of the application. When the
routing is configured properly then connecting to fc00::/8 results in
connecting to the CJDNS network.
Introduce an option so that Bitcoin Core knows whether this is the case.
This commit does not change behavior in any way. See previous commit for
complete rationale, but these flags are being disabled because they
aren't implemented and will otherwise break backwards compatibility when
they are implemented.

4747da3a5b Add syscall sandboxing (seccomp-bpf) (practicalswift)
Pull request description:
Add experimental syscall sandboxing using seccomp-bpf (Linux secure computing mode).
Enable filtering of system calls using seccomp-bpf: allow only explicitly allowlisted (expected) syscalls to be called.
The syscall sandboxing implemented in this PR is an experimental feature currently available only under Linux x86-64.
To enable the experimental syscall sandbox the `-sandbox=<mode>` option must be passed to `bitcoind`:
```
-sandbox=<mode>
Use the experimental syscall sandbox in the specified mode
(-sandbox=log-and-abort or -sandbox=abort). Allow only expected
syscalls to be used by bitcoind. Note that this is an
experimental new feature that may cause bitcoind to exit or crash
unexpectedly: use with caution. In the "log-and-abort" mode the
invocation of an unexpected syscall results in a debug handler
being invoked which will log the incident and terminate the
program (without executing the unexpected syscall). In the
"abort" mode the invocation of an unexpected syscall results in
the entire process being killed immediately by the kernel without
executing the unexpected syscall.
```
The allowed syscalls are defined on a per thread basis.
I've used this feature since summer 2020 and I find it to be a helpful testing/debugging addition which makes it much easier to reason about the actual capabilities required of each type of thread in Bitcoin Core.

[About seccomp and seccomp-bpf](https://en.wikipedia.org/wiki/Seccomp):
> In computer security, seccomp (short for secure computing mode) is a facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit(), sigreturn(), and read() and write() to already-open file descriptors. Should it attempt any other system calls, the kernel will terminate the process with SIGKILL or SIGSYS. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.
>
> […]
>
> seccomp-bpf is an extension to seccomp that allows filtering of system calls using a configurable policy implemented using Berkeley Packet Filter rules. It is used by OpenSSH and vsftpd as well as the Google Chrome/Chromium web browsers on Chrome OS and Linux. (In this regard seccomp-bpf achieves similar functionality, but with more flexibility and higher performance, to the older systrace—which seems to be no longer supported for Linux.)

Init should only concern itself with the initialization order, not the
detailed initialization logic of every module.
Also, inlining logic into a method that is ~800 lines of code, makes it
impossible to unit test on its own.
DecopeAsmap is a pure utility function and doesn't have any
dependencies on addrman, so move it to util/asmap.
Reviewer hint: use:
`git diff --color-moved=dimmed-zebra --color-moved-ws=ignore-all-space`
The class only stores the file path, reading it from a global. Globals
are confusing and make testing harder.
The method reading from a stream does not even use any class members, so
putting it in a class is also confusing.
Improve readability of code, simplify future scripted diff cleanup PRs, and be
more consistent with naming for GetBoolArg.
This will also be useful for replacing runtime settings type checking
with compile time checking.

Now that we manage the lifespan of node.addrman, we can just reset
node.addrman to a newly initialized CAddrMan if parsing peers.dat
fails, eliminating the possibility that Clear() leaves some old state
behind.
Use interfaces::Init::make* methods instead of interfaces::Make*
functions, so interfaces can be constructed differently in different
executables without having to change any code. (So for example
bitcoin-gui can make an interfaces::Node pointer that communicates with
a bitcoin-node subprocess, while bitcoin-qt can make an interfaces::Node
pointer that starts node code in the same process.)
Currently addrman consistency checks are a compile time option, and are not
enabled in our CI. It's unlikely anyone is running these consistency checks.
Make them a runtime option instead, where users can enable addrman
consistency checks every n operations (similar to mempool tests). Update
the addrman unit tests to do internal consistency checks every 100
operations (checking on every operations causes the test runtime to
increase by several seconds).
Also assert on a failed addrman consistency check to terminate program
execution.
703b1e612a Close minor startup race between main and scheduler threads (Larry Ruane)
Pull request description:
This is a low-priority bug fix. The scheduler thread runs `CheckForStaleTipAndEvictPeers()` every 45 seconds (EXTRA_PEER_CHECK_INTERVAL). If its first run happens before the active chain is set up (`CChain::SetTip()`), `bitcoind` will assert:
```
(...)
2021-07-28T22:16:49Z init message: Loading block index…
bitcoind: validation.cpp:4968: CChainState& ChainstateManager::ActiveChainstate() const: Assertion `m_active_chainstate' failed.
Aborted (core dumped)
```
I ran into this while using the debugger to investigate an unrelated problem. Single-stepping through threads with a debugger can cause the relative thread execution timing to be very different than usual. I don't think any automated tests are needed for this PR. I'll give reproduction steps in the next PR comment.

Pull request description:
This PR adds a DNS seed to the regtest chain params to enable testing the DNS seed querying logic of `CConnman::ThreadDNSAddressSeed` and relevant startup parameters. Adds coverage for the changes in #22013 (and then some).
The main behavioral change to bitcoind is that this PR disallows starting up with conflicting parameters for `-dnsseed` and `-forcednsseed`.
The tests include:
* parameter interactions of different combinations of `-connect`, `-dnsseed` and `-forcednsseed`
* the delay before querying DNS seeds depending on how many addresses are in the addrman
* the behavior of `-forcednsseed`
* skipping DNS querying if we have outbound full relay connections & not block-relay-only connections
Huge props to mzumsande for identifying the timing technique for testing successful connections before running `ThreadDNSAddressSeed` 🙌🏽

Don't schedule class PeerManagerImpl's background tasks from its
constructor, but instead do that from a separate method,
StartScheduledTasks(), that can be called later at the end of startup,
after other things, such as the active chain, are initialzed.
-dnsseed determines whether we run ThreadDNSAddressSeed and potentially query
the DNS seeds for addresses. -forcednsseed tells the node to force querying the
DNS seeds even if we have sufficient addresses or current connections.
This commit disallows starting up with explicitly conflicting parameters.

Pull request description:
Builds on #21009 and makes progress on remaining items in #17862
Removing `RewindBlockIndex()` in #21009 allows the following:
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- move `test_upgrade_after_activation()` out of `p2p_segwit.py` reducing runtime
- 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`

Since we now have multiple chainstate objects, only one of them is active at any given
time. An active chainstate has a mempool, but there's no point to others having one.
This change will simplify proposed assumeutxo semantics. See the discussion here:

Pull request description:
_This is an alternative to https://github.com/bitcoin/bitcoin/pull/21514, inspired by https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-815049933. They are mutually exclusive. Just one of them should be merged._
Change assumed ports for I2P to 0 (instead of the default 8333) as this is closer to what actually happens underneath with SAM 3.1 (https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-812632520, https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-816564719).
Don't connect to I2P peers with advertised port != 0 (we don't specify a port to our SAM 3.1 proxy and it always connects to port = 0).
Note, this change:
* Keeps I2P addresses with port != 0 in addrman and relays them to others via P2P gossip. There may be non-bitcoin-core-22.0 peers using SAM 3.2 and for them such addresses may be useful.
* Silently refuses to connect to I2P hosts with port != 0. This is ok for automatically chosen peers from addrman. Not so ok for peers provided via `-addnode` or `-connect` - a user who specifies `foo.b32.i2p:1234` (non zero port) may wonder why "nothing is happening".

2feec3ce31 net: don't bind on 0.0.0.0 if binds are restricted to Tor (Vasil Dimov)
Pull request description:
The semantic of `-bind` is to restrict the binding only to some address.
If not specified, then the user does not care and we bind to `0.0.0.0`.
If specified then we should honor the restriction and bind only to the
specified address.
Before this change, if no `-bind` is given then we would bind to
`0.0.0.0:8333` and to `127.0.0.1:8334` (incoming Tor) which is ok -
the user does not care to restrict the binding.
However, if only `-bind=addr:port=onion` is given (without ordinary
`-bind=`) then we would bind to `addr:port` _and_ to `0.0.0.0:8333` in
addition.
Change the above to not do the additional bind: if only
`-bind=addr:port=onion` is given (without ordinary `-bind=`) then bind
to `addr:port` (only) and consider incoming connections to that as Tor
and do not advertise it. I.e. a Tor-only node.

* When accepting an I2P connection, assume the peer has port 0 instead
of the default 8333 (for mainnet). It is not being sent to us, so we
must assume something.
* When deriving our own I2P listen CService use port 0 instead of the
default 8333 (for mainnet). So that we later advertise it to peers
with port 0.
In the I2P protocol SAM 3.1 and older (we use 3.1) ports are not used,
so they are irrelevant. However in SAM 3.2 and newer ports are used and
from the point of view of SAM 3.2, a peer using SAM 3.1 seems to have
specified port=0.

Provides DeploymentEnabled, DeploymentActiveAt, and DeploymentActiveAfter
helpers for checking the status of buried deployments. Can be overloaded
so the same syntax works for non-buried deployments, allowing future
soft forks to be changed from signalled to buried deployments without
having to touch the implementation code.
Replaces IsWitnessEnabled and IsScriptWitnessEnabled.

Save the banlist in `banlist.json` instead of `banlist.dat`.
This makes it possible to store Tor v3 entries in the banlist on disk
(and any other addresses that cannot be serialized in addrv1 format).
Only read `banlist.dat` if it exists and `banlist.json` does not
exist (first start after an upgrade).

Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
The first 2 commits are fixups addressing review for the last bundle: #21391
NEW note:
1. I have opened #21766 which keeps track of potential improvements where the flaws already existed before the de-globalization work, please post on that issue about these improvements, thanks!
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`

Pull request description:
net: Remove -feefilter option, as it is debug only and isn't used in any tests. Checking this option for every peer on every iteration of the message handler is unnecessary, as described in #21545.
refactor: Move feefilter logic out into a separate `MaybeSendFeefilter(...)` function to improve readability of the already long `SendMessages(...)`. fixes #21545
The configuration option `-feefilter` has been added in 9e072a6e66: _"Implement "feefilter" P2P message"_
According to the [BIP133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki), turning the fee filter off was ment for:
> [...] a node [...] using prioritisetransaction to accept transactions whose actual fee rates might fall below the node's mempool min fee [in order to] disable the fee filter to make sure it is exposed to all possible txid's
`-feefilter` was subsequently set as debug only in #8150, with the motivation that the help message was too difficult to translate.
