9f85e9cb3d scripted-diff: Rename LockAnnotation to LockAssertion (practicalswift)

cc2588579c Move LockAnnotation from threadsafety.h (imported code) to sync.h (our code) (practicalswift)
Pull request description:
`LockAnnotation lock(mutex);` is a guarantee to the compiler thread-analysis that `mutex` is locked (when it couldn't be determined otherwise).
Before this PR it was possible to make the mistake of adding a `LockAnnotation` where the correct mutex is _not_ held. This in turn makes the thread-analysis reasoning being based on incorrect premises.
This PR adds an assertion in the `LockAnnotation` ctor which checks that the guarantees given by us at compile-time are held also in practice (`ifdef DEBUG_LOCKORDER`).
Issues like the one described in #16028 will be discovered immediately with this PR merged.
Changes in this PR:
* Move `LockAnnotation` from `threadsafety.h` (imported code) to `sync.h` (our code)
* Move `LockAnnotation` in `wallet_tests` to make it reflect the truth
* Make sure the compile-time locking promises given via `LockAnnotation`:s hold also in practice at runtime (`ifdef DEBUG_LOCKORDER`)
* Rename `LockAnnotation` to `LockAssertion`

Adds doxygen comments for the CKeyPool and CReserveKey objects. The way these work is pretty confusing and it's easy to overlook details (eg https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393).

8f7b93047581c67f2133cdb8c7845471de66c30f Drop the leading 0 from the version number (Andrew Chow)
Pull request description:
Removes the leading 0 from the version number. The minor version, which we had been using as the major version, is now the major version. The revision, which we had been using as the minor version, is now the minor version. The revision number is dropped. The build number is promoted to being part of the version number. This also avoids issues where it was accidentally not included in the version number.
The CLIENT_VERSION remains the same format as previous as previously, as the Major version was 0 so it never actually got included in it.
The user agent string formatter is updated to follow this new versioning.
***
Honestly I'm just tired of all of the people asking for "1.0" that maybe this'll shut them up. Skip the whole 1.0 thing and go straight to version 22.0!
Also, this means that the terminology we commonly use lines up with how the variables are named. So major versions are actually bumping the major version number, etc.

d6e493f0c2850b522a676a005935163beddaa2cc wallet: Remove left-over BIP70 comment (Fabian Jahr)
Pull request description:
A small follow-up to #17165 which removed BIP70 support.
1. Removes one leftover mention of BIP70 in a comment.
2. Removes BIP70 reference in comments on network/chain name strings. These can be removed as they are not really helpful and also incorrect: BIP70 only defines "main" and "test" but not "regtest". If/When signet gets merged we will add another name to the list that is not defined in BIP70. Mostly there is also an exhaustive list of the options included in the comment anyway.
If we would like to keep an identifier for this naming scheme, I would suggest switching to something more generic, like 'short chain name'. Happy to implement that if that is preferred. Alternatively, we could add a reference to `CBaseChainParams`. That would also mean we don't have to change these lines again for signet.

Pull request description:
`CTxOut::nValue` is default-initialized to `-1`. The dust-threshold for `OP_RETURN` outputs is `0`. Thus, the policy failure would be `dust` instead of `multi-op-return`. The test only passes because the dust check is currently not run.
Avoid that confusion by setting the value to `0`, to ensure the dust check passes.

e95aaefe2540cb76969818fcc2ff77d33448ed5a build: Avoid secp256k1.h include from system (Niklas Gögge)
Pull request description:
While building i ran into an error because i had a version of `secp256k1.h` under `/usr/local/include` that was incompatible with the secp256k1 code in the repository. This caused a problem because `$(BOOST_CPPFLAGS)` contained `-I/usr/local/include` and the include paths are searched by the compiler in order from left to right, so in the end `$(BITCOIN_INCLUDES)` contained `-I/usr/local/include` before `-I$(srcdir)/secp256k1/include` which caused the compiler to find `secp256k1.h` under `/usr/local/include`.
Looking at git blame i am wondering how this has not happened to anyone else in several years: cb89e18845/src/Makefile.am (L25)

bd5215103eb3985c1622eddea45a040e6173829c random: fixes read buffer resizing in RandAddSeedPerfmon (Ethan Heilman)
Pull request description:
As shown below when resizing the read buffer `vData` `std::max((vData.size() * 3) / 2, nMaxSize)` is used. This means that the buffer size immediately jumps to `nMaxSize`. I believe the intend of this code is to grow the buffer size through several steps rather than immediately resize it to the max size.
```cpp
std::vector<unsigned char> vData(250000, 0);
long ret = 0;
unsigned long nSize = 0;
const size_t nMaxSize = 10000000; // Bail out at more than 10MB of performance data
while (true) {
nSize = vData.size();
ret = RegQueryValueExA(HKEY_PERFORMANCE_DATA, "Global", nullptr, nullptr, vData.data(), &nSize);
if (ret != ERROR_MORE_DATA || vData.size() >= nMaxSize)
break;
vData.resize(std::max((vData.size() * 3) / 2, nMaxSize)); // Grow size of buffer exponentially
}
```
vData always starts at size 250,000 and nMaxSize is always 10,000,000 so the first time this line is reached:
```cpp
vData.resize(std::max((vData.size() * 3) / 2, nMaxSize));
```
the effect will always be to resize vData to nMaxSize. Then because the loop terminates when vData.size >= 10,000,000 only one resize operation will take place.
To fix this issue we replace `std::min` with `std::max`
This PR also adds a comment clarifying the behavior of this function the first time it is called.

e90e3e684ffa7b25f0dfb5b45e70bb0c358261fb build: fix sysctl() detection on macOS (fanquake)
Pull request description:
[`sysctl()` on *BSD](https://www.unix.com/man-page/FreeBSD/3/sysctl/) takes a "const int *name", whereas [`sysctl()` on macOS](https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/sysctl.3.html)
it takes an "int *name". So our configure check and `sysctl()` detection on
macOS currently fails:
```bash
/usr/include/sys/sysctl.h:759:9: note: candidate function not viable:
no known conversion from 'const int [2]' to 'int *' for 1st argument
int sysctl(int *, u_int, void *, size_t *, void *, size_t);
```
The simplest change seems to be to change the param to a "int *name", which
will work during configure on macOS and *BSD systems.
For consistency I've changed both calls, but note that macOS doesn't
have `KERN_ARND`, so that check will always fail regardless. We can revert/add
documentation if preferred.

461e547877da0c04db69e067c923cc4540aab03a doc: correct random.h docs after #17270 (fanquake)
Pull request description:
The usage of `MilliSleep()` in SeedPeriodic (previously SeedSleep) was
[removed](d61f2bb076) in #17270, meaning it, and its users can now be marked `noexcept`.
This also corrects the docs in random.h for some of the changes in #17270.

ba2c5fe1477cec80d7e02f824daba21a1021758e Fix CPUID subleaf iteration (Pieter Wuille)
Pull request description:
This fixes#17523.
The code to determine which CPUID subleaves to explore was incorrect in #17270. The new code here is based on Intel's reference documentation for CPUID (a document called "Intel® Processor Identification and the CPUID Instruction - Application Note 485", which I cannot actually find on their own website).

* compat: remove bswap_* check on macOS
This was originally added in #9366 to fix the gui build, as
Protobuf would also define these macros. Now that we're no-longer
using Protobuf, remove the additional check.

* build: remove OpenSSL from Qt build
More info available from:
https://doc.qt.io/qt-5/ssl.html#enabling-and-disabling-ssl-support
* build: remove EVP_MD_CTX_new detection
This was added in #9475 to fix LibreSSL compatibility for
BIP70, so is no longer required.
* build: remove SSL lib detection
* gui: update BIP70 support message
* build: remove BIP70 entries from macOS Info.plist
* gui: remove payment request file handling from OpenURI dialog

* refactor(instantsend): make cs_db a Mutex
This introduces GetInstantSendLockByHashInternal and GetInstantSendLockHashByTxidInternal as they are called in Locked and Unlocked contexts. The Internal functions do not lock cs_db, the non-internal functions simply lock cs_db then call the internal function. This ensures saftety (all public functions lock cs_db immediately & all private functions have cs_db already locked) enforced via clang thread safety, while allowing us to use a Mutex here
* refactor(instantsend): remove CInstantSendManager::cs, replace it with cs_inputReqests, cs_creating, cs_pendingLocks, cs_nonLocked, cs_pendingRetry
LOCKS_EXCLUDED are used everywhere where the associated mutex is locked ensuring that deadlocks are impossible

275e9390e1c84ac021b3c781ee239ad9ba7b78d4 mining, refactor: add m_mempool.cs thread safety lock assertions (Jon Atack)
Pull request description:

These functions have thread safety lock annotations in their declarations but are missing the corresponding run-time lock assertions in their definitions.

9dd58ca611f6f2b59c25d727a4e955333525d345 init: Stop indexes on shutdown after ChainStateFlushed callback. (Jim Posen)
Pull request description:
Replaces https://github.com/bitcoin/bitcoin/pull/17852.
Currently, the latest index state may not be committed to disk on shutdown. The state is committed on `ChainStateFlushed` callbacks and the current init order unregisters the indexes as validation interfaces before the final `ChainStateFlushed` callback is called on them.
Issue identified by paulyc.
For review: an alternative or supplemental solution would be to call `Commit` at the end of `BaseIndex::Stop`. I don't see any harm in doing so and it makes the less prone to user error. However, the destructor would have to be modified to not call `Stop` because `Commit` calls a virtual method, so I figured it wasn't worth it. But I'm curious how others feel.

f1a0314c537791f202dfb7c1209f0e04ba7988c3 gui: change combiner for signals to optional_last_value (Cory Fields)
Pull request description:
[`optional_last_value`](https://www.boost.org/doc/libs/1_73_0/doc/html/boost/signals2/optional_last_value.html), which does not throw, has replaced `last_value` as
Boosts default combiner. Besides being better supported, it also doesn't
trigger gcc's `-Wmaybe-unitialized` warning, presumably because exceptions no
longer bubble-up out of signals:

The change in default happened in [Boost 1.39.0](https://www.boost.org/users/history/version_1_39_0.html) (along with the introduction of the Signals2 library.
More information is also available here https://www.boost.org/doc/libs/1_73_0/doc/html/signals2/rationale.html#id-1.3.36.9.4:
> The default combiner for Boost.Signals2 has changed from the last_value combiner used by default in the original Boost.Signals library.
> This is because last_value requires that at least 1 slot be connected to the signal when it is invoked (except for the last_value<void> specialization).
> In a multi-threaded environment where signal invocations and slot connections and disconnections may be happening concurrently, it is difficult to fulfill this requirement. When using optional_last_value, there is no requirement for slots to be connected when a signal is invoked, since in that case the combiner may simply return an empty boost::optional.

c1c6c410a66996b2d60d5172189b5a5ec8100842 test: add reason checks for non-standard txs in test_IsStandard (Sebastian Falbesoner)
Pull request description:
While taking a look at #17272 I noticed that for some reason the unit test `test_IsStandard` (which was not adapted to the policy change in the referenced PR commits) didn't fail as expected:
6a97e8a060/src/test/transaction_tests.cpp (L758-L762)
It turned out that `IsStandardTx()` returned `"dust"` as rejection reason (instead of the expected `"multi-op-return"`), leading to the conclusion that 5fe6f052bd erroneously performs the `IsDust()` check also for TX_NULL_DATA transactions. To avoid cases like this in the future, this PR makes the unit test `test_IsStandard` more strict by also checking for the concrete reason after each occurence of `IsStandardTx()` returning false.

Tested ACK 091747b46ecf06244ce2650028f1833b2e7c5062 - this is an improvment. Further solutions to solve the interference between the console and the shortcuts (if possible) can be done upstream (Qt) or with another PR.

Pull request description:
I thought this wouldn't work for some reason, but it seems it does.
Just a little bit more consistency. I'm still not able to use them in qt/networkstyle.cpp though, not sure why.

fa398091b7ad683dfd3cd3c2cd030eaf9f336737 Avoid unused call to GuessVerificationProgress in NotifyHeaderTip (MarcoFalke)
Pull request description:
`GuessVerificationProgress` for a header (not a block) is always 0 because the number of txs in the block can not be determined from the header alone. Anyway, this result was never used, so we can optimize this call by hardcoding 0.
This is the next commit in a series of changes toward removing nChainTx (see #14863, #13875)

04dbdd613fe5c0a742de915e07553614cd4cbf46 [net] SocketHandler: log peer id for close and disconnect (Sjors Provoost)
Pull request description:
When combined with `-logips` this makes it easier to diagnose disconnects.
To test on macOS, find a connection you want to disrupt:
```
lsof -nP -iTCP:8333 -sTCP:ESTABLISHED
```
To shut it down gracefully you can use tcpkill or this Python script: https://github.com/google/tcp_killer
The log should say:
```
2019-10-25T13:26:55Z socket closed for peer=1
2019-10-25T13:26:55Z disconnecting peer=1
2019-10-25T13:26:55Z Cleared nodestate for peer=1
```
To shut it down ungracefully I made a patch to the above script, adding a `-force` argument. _Careful, this may result in data corruption_. Then the log should say:
```
2019-10-25T13:39:57Z socket select error Bad file descriptor (9)
2019-10-25T13:39:57Z socket recv error for peer=0: Bad file descriptor (9)
2019-10-25T13:39:57Z disconnecting peer=0
2019-10-25T13:39:57Z Socket close failed: 35. Error: Bad file descriptor (9)
2019-10-25T13:39:57Z Cleared nodestate for peer=0

* chore: bump MIN_PEER_PROTO_VERSION to 70215
simplifies logic, removes branches
This protocol version is from v14 in May of 2019, should be more than safe to bump this
* drop MIN_COINJOIN_PEER_PROTO_VERSION

Trying to use them results in "Error parsing command line arguments: Invalid parameter" error. Should either add them to hidden_args or drop them. The latter seems like a better option since no one should be using them by now anyway.

While C++20 is currently unsupported, I don't see any downside to a minor fixup to an example benchmark. This will also make a hypothetical C++20 patch smaller.

It doesn't seem ideal to have an integer sanitizer enabled, but then disable it for the whole validation.cpp file.
This removes one of the two violations.

29e983386b0aecf99cdb7d0e08ba6b450bed313e Fixes Bug in Transaction generation in ComplexMempool benchmark (Shorya)
Pull request description:
This fixes issues with `ComplexMempool` benchmark introduced in [#17292](https://github.com/bitcoin/bitcoin/pull/17292) , this stress test benchmarks performance of ancestor and descendant tracking of mempool graph algorithms on a complex Mempool.
This Benchmark first creates 100 base transactions and stores them in `available_coins` vector. `available_coins` is used for selecting ancestor transactions while creating 800 new transactions. For this a random transaction is picked from `available_coins` and some of its outputs are mapped to the inputs of the new transaction being created.
Now in case we exhaust all the outputs of an entry in `available_coins` then we need to remove it from `available_coins` before the next iteration of choosing a potential ancestor , it is now implemented with this patch.
As the index of the entry is randomly chosen from `available_coins` , In order to remove it from the vector , if index of the selected entry is not at the end of `available_coins` vector , it is swapped with the entry at the back of the vector , then the entry at the end of `available_coins` is popped out.
Earlier the code responsible for constructing outputs of the newly created transaction was inside the loop used for assigning ancestors to the transaction , which does some unnecessary work as it creates outputs of the transaction again and again , now it is moved out of the loop so outputs of the transaction are created just once before adding it to the final list of the transactions created. This one is a minor change to save some computation.
These changes have changed the `ComplexMempool` benchmark results on `bitcoin:master` as follows :

c43aa623435a277a692dbde784e8a7146f5573e9 Avoid excessive lock contention in CCheckQueue::Add (Hennadii Stepanov)
Pull request description:
This PR significantly reduces lock contention in the `CCheckQueue` class by releasing a mutex before calling `std::condition_variable::notify_one` and `std::condition_variable::notify_all`.
From C++ [docs](https://en.cppreference.com/w/cpp/thread/condition_variable/notify_one):
> The notifying thread does not need to hold the lock on the same mutex as the one held by the waiting thread(s); in fact doing so is a pessimization, since the notified thread would immediately block again, waiting for the notifying thread to release the lock.
