876ac3f6b62087fb5c22b0a477751895915d47b8 [tools] Allow argument/parameter bin packing in clang-format (John Newbery)
Pull request description:
clang-format documentation for BinPackArguments:
If `false`, a function call’s arguments will either be all on the same line or will have one line each.
```
true:
void f() {
f(aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
}
false:
void f() {
f(aaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
}
```
https://clang.llvm.org/docs/ClangFormatStyleOptions.html#configurable-format-style-options
There's no reason to forbid this format. Having multiple arguments or parameters per line can be just as readable as having one per line (and is certainly more readable than having extremely long lines).

Pull request description:
Darwin targets do not have a `protected` visibility function attribute, see [LLVM explanation](8e9a505139/clang/lib/Basic/Targets/OSTargets.h (L131)). This means that the `AX_GCC_FUNC_ATTRIBUTE` check for `visibility` fails:
```bash
configure:24513: checking for __attribute__((visibility))
configure:24537: g++ -std=c++11 -o conftest -g -O2 -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS -DMAC_OSX -DOBJC_OLD_DISPATCH_PROTOTYPES=0 -Wl,-headerpad_max_install_names conftest.cpp >&5
conftest.cpp:35:56: warning: target does not support 'protected' visibility; using 'default' [-Wunsupported-visibility]
int foo_pro( void ) __attribute__((visibility("protected")));
^
1 warning generated.
configure:24537: $? = 0
configure:24550: result: no
```
This leads to `EXPORT_SYMBOL` being [defined to nothing](f4de89edfa/src/script/bitcoinconsensus.h (L29)), as `HAVE_FUNC_ATTRIBUTE_VISIBILITY` is not defined, and when building with reduced exports, you end up with a libbitcoinconsensus.dylib that doesn't export any `_bitcoinconsensus_*` symbols.
```bash
➜ git:(master) nm -C src/.libs/libbitcoinconsensus.dylib | rg _bitcoinconsensus_
➜ git:(master)
```
We do have a [second check](f4de89edfa/configure.ac (L882)) for the `visibility` attribute, which works for Darwin as it's only testing for default visibility, however the result of this check isn't used at all. It was added in #4725, along with the `--enable-reduce-exports` option, however when libbitcoinconsensus was added in #5235, it used the results of the added `AX_GCC_FUNC_ATTRIBUTE` calls.
This PR removes our usage of the AX_GCC_FUNC_ATTRIBUTE macro entirely, in favour of our own checks in configure. This meant adding a check for `dllexport`, which I've tested as working with both [GCC](https://gcc.gnu.org/onlinedocs/gcc/Microsoft-Windows-Function-Attributes.html) and [Clang](https://releases.llvm.org/10.0.0/tools/clang/docs/AttributeReference.html#dllexport) when building for Windows. I haven't added an equivalent check for `dllimport`, as we weren't actually using the result of that check, we're just testing that `MSC_VER` was defined before using.
With these changes building a libbitcoinconsensus with reduced exports, when targeting Darwin, works as expected:
```bash
./autogen.sh
./configure --disable-tests --disable-bench --with-utils=no --with-daemon=no --with-gui=no --disable-wallet --with-libs=yes --enable-reduce-exports
make -j8
...

00000000000097e0 T _bitcoinconsensus_verify_script_with_amount
000000000000a3c0 T _bitcoinconsensus_version
```
```python
>>> import ctypes
>>> consensus = ctypes.CDLL("src/.libs/libbitcoinconsensus.dylib")
>>> print(consensus.bitcoinconsensus_version())
1
>>> exit()
```

Debug logs should not be printed to stdout, stderr exists for it.
Private keys should not be printed to console by activation very general
macros name "ENABLE_DASH_DEBUG".
This macros is used only for hdchain private keys, the location util/system.h
is too general for it.
Functional test "tool_wallet.py" is failed due to unexpected output for tsan.
It seems as easier to remove this logs due to too many issues with it
rather than address all of them.

e1e7a90d5f0616a46ffadd62a9f1c65406cca6b4 wallettool: Add dump command (Andrew Chow)
Pull request description:
Adds two commands to the `bitcoin-wallet` tool: `dump` and `createfromdump`. These commands will be useful for a wallet storage migration in the future. It is also generally useful to have a storage agnostic dump like this. These commands are similar to BDB's `db_dump` and `db_load` tools. This can also be useful for manual construction of a wallet file for tests.
`dump` outputs every key-value pair from the wallet as comma separated hex. Each key-value pair is on its own line with the key and value in hex separated by a comma. This is output to the file specified by the new `-dumpfile` option.
`createfromdump` takes a file produced by `dump` and creates a new wallet file with exactly the records specified in that file.
A new option `-dumpfile` is added to the wallet tool. When used with `dump`, the records will be written to the specified file. When used with `createfromdump`, the file is read and the key-value pairs constructed from it. `createfromdump` requires `-dumpfile`.
A simple round-trip test is added to the `tool_wallet.py`.

Since bitcoin#21186, mutual exclusivity is not a given (i.e.
RelayAddrsWithConn != !IsBlockOnlyConn), we should use RelayPeersWithConn
for a definitive answer and since relying on a no-longer-true property
breaks InstantSend, let's fetch the right answer instead.
Dash uses a lot more CNode::RelayAddrsWithConn checks than Bitcoin (esp.
since a483122f (#4888)), so bitcoin#21186 will not adequately cover the
removal of RelayAddrsWithConn usages.
When possible to query with RelayAddrsWithPeer, that should be used, as
that value is the most reliable, else we rely on the former mutual
exclusivity of IsBlockOnlyConn and RelayAddrsWithConn to fill in the
blanks where a more reliable query isn't available.
Note: To prevent builds from breaking, a change has been made in
InstantSend code despite it breaking functionality. A commit later will
repair it by creating a way to access RelayAddrsWithPeer.
comment was moved to net.h in 678df631 (#4888) and removed entirely in
796353ad (#5771). the comment is being restored back to where it is
upstream, in CNode::RelayAddrsWithConn.

Pull request description:
To enable lock contention logging, `DEBUG_LOCKCONTENTION` has to be defined at compilation. Once built, the logging is not limited to a category and is high frequency, verbose and in all-caps. With these factors combined, it seems likely to be rarely used.
This patch:
- adds a `lock` logging category
- adds a timing macro in microseconds, `LOG_TIME_MICROS_WITH_CATEGORY`
- updates `BCLog::LogMsg()` to omit irrelevant decimals for microseconds and skip unneeded code and math
- improves the lock contention logging, drops the all-caps, and displays the duration in microseconds
- removes the conditional compilation directives
- allows lock contentions to be logged on startup with `-debug=lock` or at run time with `bitcoin-cli logging '["lock"]'`

Moving out of a variable technically leaves it in an unspecified and potentially invalid state; yet I don't see anywhere we are reseting or otherwise clearing pendingContributionVerifications to ensure it is valid. Instead simply take a ref to it; and then clear it at the end.

ded1b5a3df fix: deadlock over cs_main and contributionsCacheCs in dkssessionmgr (Konstantin Akimov)
Pull request description:
## Issue being fixed or feature implemented
**It fixes rpc failure: "Work queue depth exceeded"**
As I checked on running `dashd` in deadlock condition:
Thread 78 is a thread that keep `cs_main`:
```
#14 0x0000aaaad1f8d604 in BuildSimplifiedMNListDiff () at evo/simplifiedmns.cpp:364
```
but it is locked by `contributionsCacheCs`
```
#8 llmq::CDKGSessionManager::GetVerifiedContributions () at llmq/dkgsessionmgr.cpp:392
```
On other hand, `contributionsCacheCs` is blocked by Thread 59
```
#17 0x0000aaaad1ba1940 in llmq::CDKGSessionManager::GetVerifiedContributions () at llmq/dkgsessionmgr.cpp:393
```
and it makes circuit lock by waiting `cs_main` in
```
#9 ReadBlockFromDisk () at node/blockstorage.cpp:75
```
See https://github.com/dashpay/dash-issues/issues/69 for more details
Seems introduced there: dashpay/dash#3911
## What was done?
Deadlock is removed by reducing scope of mutex
## How Has This Been Tested?
I reviewed 2 different servers which have status `work queue exceeded`, both have same deadlock, so, this patch should fix this issue. Once this fix is merged, we can test it on testnet.

## Issue being fixed or feature implemented
Refactor extracted from #5860. Even if that PR should not need anymore this commit (since it has been found a better way to activate dip143), I think It's still a worthy refactor
## What was done?
Introduce `tx.IsSpecialTxVersion()` in place of `tx.nVersion == 3`, `tx.nVersion >= 3`
and `tx.HasExtraPayloadField()` in place of `tx.nVersion == 3 && tx.nType != TRANSACTION_NORMAL`

Pull request description:
## Additional Information
* `CActiveMasternodeManager`, unlike other managers, is _conditionally_ initialized (specifically, when the node is hosting a masternode). This means that checks need to be made to ensure that the conditions needed to initialize the manager are true or that the pointer leads to a valid manager instance.
As the codebase currently checks (and fast-fails) based on the node being in "masternode mode" (`fMasternodeMode`) or not, we will continue with this approach, but with additional assertions _after_ the masternode mode check if the manager exists.
* Though, since `activeMasternodeInfo`(`Cs`) are global variables, they can be accessed _regardless_ of whether the corresponding manager exists. This means some parts of the codebase attempt to fetch information about the (nonexistent) active masternode _before_ determining if it should use the masternode mode path or not (looking at you, `CMNAuth::ProcessMessage`)
Moving them into `CActiveMasternodeManager` meant adding checks _before_ attempting to access information about the masternode, as they would no longer be accessible with dummy values ([here](2110c0c309/src/init.cpp (L1633-L1635))) on account of being part of the conditionally initialized manager.
* In an attempt to opportunistically dereference the manager, `CDKGSessionManager` (accepting a pointer) was dereferencing the manager before passing it to `CDKGSessionHandler`. This was done under the assumption that `CDKGSessionManager` would only ever be initialized in masternode mode.
This is not true. I can confirm that because I spent a few days trying to debug test failures. `CDKGSessionHandler` is initialized in two scenarios:
* In masternode mode
* If the `-watchquorums` flag is enabled
The latter scenario doesn't initialize `CActiveMasternodeManager`.
Furthermore, the DKG round thread is started unconditionally ([here](2110c0c309/src/llmq/context.cpp (L79))) and the `CDKGSessionHandler::StartThreads` > `CDKGSessionHandler::StartThread` > `CDKGSessionHandler::PhaseHandlerThread` > `CDKGSessionHandler::HandleDKGRound` > `CDKGSessionHandler::InitNewQuorum` > `CActiveMasternodeManager::GetProTxHash` call chain reveals an attempt to fetch active masternode information without any masternode mode checks.
This behaviour has now been changed and the thread will only be spun up if in masternode mode.
* Dereferencing so far has been limited to objects that primarily hold data (like `CCoinJoinBroadcastTx` or `CGovernanceObject`) as they should not have knowledge of node's state (that responsibility lies with whatever manager manipulates those objects), perform one-off operations and static functions.
* `activeMasternodeInfo` allowed its members to be read-write accessible to anybody who asked. Additionally, signing and decrypting involved borrowing the operator secret key from the active masternode state to perform those operations.
This behaviour has now been changed. The internal state is now private and accessible read-only as a const ref (or copy) and `Decrypt`/`Sign` functions have been implemented to allow those operations to happen without having another manager access the operator private key in order to do so.
* You cannot combine a `WITH_LOCK` and an `Assert` (in either mutex or accessed value), doing so will cause errors if `-Werror=thread-safety` is enabled. This is why `assert`s are added even when it would intuitively seem that `Assert` would've been more appropriate to use.
## Future Considerations
Currently there are no unit tests that test the functionality of `CActiveMasternodeManager` as it's never initialized in test contexts, breakage had to be found using functional tests. Perhaps some (rudimentary) tests for `CActiveMasternodeManager` may prove to be valuable.
## Breaking Changes
Not _really_. Some behaviour has been modified but nothing that should necessitate updates or upgrades.

Pull request description:
## Additional Information
* [bitcoin#19884](https://github.com/bitcoin/bitcoin/pull/19884) doesn't seem to play nice on its own and necessitated two more backports (namely [bitcoin#21165](https://github.com/bitcoin/bitcoin/pull/21165) and [bitcoin#21254](https://github.com/bitcoin/bitcoin/pull/21254)) before it did.
* Trying to find why that is has been time consuming but there doesn't seem to be a concrete answer. If running the daemon normally (`dashd --regtest --dnsseed=1`), the functionality behaves as expected but the test still fails.
* The closest explanation is that our OOO backports with relation to mocking time could explain why it isn't working as expected due to debug statements I added that always shown the time delta between each "enough time has passed" check was 0 seconds even when the log was advancing forward in time.
* The usage of `dnsseed=0` stems from [bitcoin#16551](https://github.com/bitcoin/bitcoin/pull/16551) (link to diff in commit comment), a backport that was skipped due to complexity. Though, some aspects of the PR have made it with [dash#3946](https://github.com/dashpay/dash/pull/3946).
* [bitcoin#19829](https://github.com/bitcoin/bitcoin/pull/19829) does away with `CConnman::ForEachNode` usage in `PeerManagerImpl::UpdatedBlockTip` ([source](https://github.com/bitcoin/bitcoin/pull/19829/files#diff-6875de769e90cec84d2e8a9c1b962cdbcda44d870d42e4215827e599e11e90e3R1318-R1328)). Dash cannot do the same and continues to use `ForEachNode` as we use the `CNode::CanRelay` check, which is not accessible through the `Peer` struct.
* It would be valuable to find values that are Dash-specific (like `m_masternode_connection`) and migrate them to `Peer` to avoid Dash-specific patches and closer alignment with upstream.
## Breaking Changes
Potential change in behaviour in the GUI and RPC.
In RPC, `getpeerinfo` will now display `pingwait` and `startingheight` if `fStateStats` is true (earlier behaviour was unconditional). `startingheight` has been placed below `banscore` (earlier behaviour placed it above). In the GUI (Qt), `peerHeight` and `peerPingWait` are subject to similar conditionality as mentioned earlier.
No changes in protocol or consensus. Changes are primarily related to refactoring, cleaning up, improving networking code and adding a new flag (`-fixedseeds`).
