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.

  This PR is extracted from https://github.com/bitcoin/bitcoin/pull/13816 to make that one easier to review. It follows on https://github.com/bitcoin/bitcoin/pull/13849 and https://github.com/bitcoin/bitcoin/pull/13851

  In here the shell script parts from `travis.yml` are extracted into `.travis/before_install.sh`, `.travis/install.sh`, `.travis/before_script.sh`, `.travis/script.sh`, and `.travis/lint.sh`.

  This has the benefit that `test/lint/lint-shell.sh` will also shellcheck these parts. Also it makes the individual script parts more readable.

Merge #12676: Show "bip125-replaceable" flag, when retrieving mempool entries
870bd4c73d Update functional RBF test to check replaceable flag (dexX7)
820d31f95f Add "bip125-replaceable" flag to mempool RPCs (dexX7)

Pull request description:

  This pull request adds a flag "bip125-replaceable" to the mempool RPCs getrawmempool, getmempoolentry, getmempoolancestors and getmempooldescendants, which indicates whether an unconfirmed transaction might be replaced.

  Initially the flag was added to the raw transaction RPCs, but thanks to @conscott, it was moved to the mempool RPCs, which actually have access to the mempool.

  ~~This pull request adds a flag "bip125-replaceable" to the RPCs "getrawtransaction" and "decoderawtransaction", which indicates, whether a transaction signals BIP 125 replaceability.~~

  There was some discussion in #7817, whether showing replaceability in the UI could lead to the false assumption that transactions that don't signal BIP 125 are truely non-replaceable, but given that this PR tackles the raw transaction interface, which is a rather low level tool, I believe having this extra piece of information isn't bad.

48618daf26 Add checks for settxfee reasonableness (Anthony Towns)

Pull request description:

  When using the `settxfee` RPC, the value is silently ignored if it is less than either than minrelaytxfee or the wallet's mintxfee. This adds an error response if that's going to happen, but still allows "settxfee 0" to deliberately default to the minimum value.

  Fix this by refusing to sign if there is any mismatch between the provided data and what is being signed.

Pull request description:

  Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.

  Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.

  An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Merge #13928: qa: blocktools enforce named args for amount
cf9ed307e6 qa: blocktools enforce named args for amount (MarcoFalke)

Pull request description:

  Since  #13669 changed some signatures, I think it might be worthwhile to enforce named args for primitive types such as amounts.

Merge #13918: rpc: Replace median fee rate with feerate percentiles in getblockstats
4b7091a842 Replace median fee rate with feerate percentiles (Marcin Jachymiak)

Pull request description:

  Currently,  the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.

  This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles.  This more accurately corresponds with what is generally meant by median feerate.

Merge #13666: Always create signatures with Low R values
e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)

Pull request description:

  When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.

  Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.

  Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.

  DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.
