Merge #14122: Test rpc_help.py failed: Check whether ZMQ is enabled or not.
8dfc2f30de Test rpc_help.py failed: Check whether ZMQ is enabled or not. (Kvaciral)

Pull request description:

  /test/functional/rpc_help.py checks for the zmq-category even while zmq may be disabled (in /test/config.ini) , I have added a check function to test_framework.py that can be used whether to determine to include zmq in a test or not.

Merge #11599: scripted-diff: Small locking rename
190bf62be1 scripted-diff: Small locking rename (Russell Yanofsky)

Pull request description:

  Call sync.h primitives "locks" and "mutexes" instead of "blocks" and "waitable critical sections" to match current coding conventions and c++11 standard names.

  This PR does not rename the "CCriticalSection" class (though this could be done as a followup) because it's used everywhere and would swamp the other changes in this PR. Plain mutexes should mostly be preferred instead of recursive mutexes in new code anyway.

Merge #14088: tests: Don't assert(...) with side effects
ca1a093127 Add regression test: Don't assert(...) with side effects (practicalswift)
4c3c9c3869 Don't assert(...) with side effects (practicalswift)

Pull request description:

  Don't `assert(...)` with side effects.

  From the developer notes:

  > **Assertions should not have side-effects**
  >
  > Rationale: Even though the source code is set to refuse to compile with assertions disabled, having side-effects in assertions is unexpected and makes the code harder to understand

  These assertions were introduced quite recently (in #14069 which was merged two days ago) and since this is a recurring thing (see #13534 – "Don't assert(foo()) where foo() has side effects" from May) I added a simple regression test for the most obvious common side effect.

Currently we log a message indicating that a bitcoin.conf file is being used
even if one does not exists. This commit changes the logic to only display
this message if a config file exists and logs a separate message
if no config file exists. Additionally, a warning is now logged if the file
path passed in the -conf flag does not exist.

Merge #14097: validation: Log FormatStateMessage on ConnectBlock error in ConnectTip
fa309dc305 validation: Log FormatStateMessage on ConnectBlock error in ConnectTip (MarcoFalke)

Pull request description:

  This change additionally logs the validation state on error, which is not logged at all on current master.

  Before:
  ```
  ERROR: ConnectTip(): ConnectBlock ffffff.... failed
  ```

  After:
  ```
  ERROR: ConnectTip: ConnectBlock ffffff.... failed, bad-cb-amount (code 16)
  ```

Merge #13792: tx pool: Avoid passing redundant hash into addUnchecked (scripted-diff)
fa587773e5 scripted-diff: Remove unused first argument to addUnchecked (MarcoFalke)
fe5c49766c tx pool: Use the entry's hash instead of the one passed to addUnchecked (MarcoFalke)
ddd395f968 Mark CTxMemPoolEntry members that should not be modified const (MarcoFalke)

Pull request description:

  Several years ago the transaction hash was not cached. For optimization the hash was instead passed into `addUnchecked` to avoid re-calculating it. See f77654a0e9

  Passing in the hash is now redundant and the argument can safely be removed.

Merge #14020: Add tests for RPC help
6af6d9b23d test: Add tests for RPC help (João Barbosa)

Pull request description:

  At the moment the new test checks for:
   - invalid usages
   - expected output for unknown command
   - current RPC command titles (derived from command categories) — this prevents adding wrong RPC categories and new categories must be added to the test

Merge #13671: Remove the boost/algorithm/string/case_conv.hpp dependency
b193d5a443 Removes the Boost case_conv.hpp dependency. (251)
7a208d9fad Implements custom tolower and toupper functions. (251)
e2ba043b8d Implements ParseNetwork unit test. (251)

Pull request description:

  This pull request removes the `boost/algorithm/string/case_conv.hpp` dependency from the project.

  `boost/algorithm/string/case_conv.hpp` is included for the `boost::to_lower` and `boost::to_upper` template functions.

  We can replace the calls to these functions with straightforward alternative implementations that use the C++ Standard Library, because the functions are called with `std::string` objects that use standard 7-bit ASCII characters as argument.

  The refactored implementation should work without the explicit `static_cast<unsigned char>` cast and `unsigned char` lambda return type. Both have been added defensively and to be explicit. Especially in case of the former, behaviour is undefined (potentially result in a crash) if the `std::toupper` argument is not an `unsigned char`.

  A potential alternative, maybe even preferred, implementation to address the `boost::to_lower` function call in `ParseNetwork(std::string)` could have been:

  ```c++
  if (net == "ipv4" || net == "IPv4") return NET_IPV4;
  if (net == "ipv6" || net == "IPv6") return NET_IPV6;
  ```
  This alternative implementation would however change the external behaviour of `ParseNetwork(std::string)`.

  This pull requests includes a unit test to validate the implementation of `ParseNetwork(std::string)`  prior and after the removal of the `case_conv.hpp` dependency.

  `boost/algorithm/string/case_conv.hpp` has been removed from the `EXPECTED_BOOST_INCLUDES` in `test/lint/lint-includes.sh` because it is no longer required.
