Merge #13355: Fix "gmake check" under OpenBSD 6.3 (probably *BSD): Avoid using GNU grep specific regexp handling
db56755ca4 Fix "gmake check" under OpenBSD 6.3 (probably *BSD): Avoid using GNU grep specific regexp handling (practicalswift)

Pull request description:

  Fixes #13337 (!)

  GNU grep and BSD grep differs in the way they handle regexps when extended regular expressions are not enabled via the `-E` flag:

  ```
  $ grep --version | head -1
  grep (GNU grep) 3.1
  $ echo "BOOST_FIXTURE_TEST_SUITE(foo)" | grep "BOOST_FIXTURE_TEST_SUITE(\|BOOST_AUTO_TEST_SUITE("
  BOOST_FIXTURE_TEST_SUITE(foo)
  $
  ```

  ```
  $ grep --version | head -1
  grep version 0.9
  $ echo "BOOST_FIXTURE_TEST_SUITE(foo)" | grep "BOOST_FIXTURE_TEST_SUITE(\|BOOST_AUTO_TEST_SUITE("
  $
  ```

  The portable way to do it is:

  ```
  $ echo "BOOST_FIXTURE_TEST_SUITE(foo)" | grep -E "(BOOST_FIXTURE_TEST_SUITE\\(|BOOST_AUTO_TEST_SUITE\\()"
  BOOST_FIXTURE_TEST_SUITE(foo)
  $
  ```

Merge #13309: Directly operate with CMutableTransaction in SignSignature
6b8b63af14 Generic TransactionSignatureCreator works with both CTransaction and CMutableTransaction (Martin Ankerl)

Pull request description:

  Refactored `TransactionSignatureCreator` into a templated `GenericTransactionSignatureCreator` that works with both `CMutableTransaction` and `CTransaction`.

  The advantage is that now in `SignSignature`, the `MutableTransactionSignatureCreator` can now operate directly with the `CMutableTransaction` without the need to copy the data into a `CTransaction`.

  Running all unit tests brings a very noticable speedup on my machine:

      48.4 sec before this change
      36.4 sec with this change
      --------
      12.0 seconds saved

  running only `--run_test=transaction_tests/test_big_witness_transaction`:

      16.7 sec before this change
       5.9 sec with this change
      --------
      10.8 seconds saved

  This relates to my first attempt with the const_cast hack #13202, and to the slow unit test issue #10026.

  Also see #13050 which modifies the tests but not the production code (like this PR) to get a speedup.

  Since gArgs is used for everything that has command line arguments, `bitcoind`, `bitcoin-cli`, `bitcoin-qt`, `bitcoin-tx`, and `bench_bitcoin` are all effected by this change and all now have the same argument checking behavior.

Pull request description:

  ReserveKeyFromKeyPool's previous behaviour is to set nIndex to -1 if the keypool is
  empty, OR throw an exception for technical failures. Instead, we now return false
  if the keypool is empty, true if the operation succeeded.

  This is to make failure more easily detectable by calling code.

Merge #13194: Remove template matching and pseudo opcodes
c814e2e7e8 Remove template matching and pseudo opcodes (Pieter Wuille)

Pull request description:

  The current code contains a rather complex script template matching engine, which is only used for 3 particular script types (P2PK, P2PKH, multisig). The first two of these are trivial to match for otherwise, and a specialized matcher for multisig is both more compact and more efficient than a generic one.

  The goal is being more flexible, so that for example larger standard multisigs inside SegWit outputs are easier to implement.

  As a side-effect, it also gets rid of the pseudo opcodes hack.

Wladimir J. van der Laan 3d4fa83587 Stop translating command line options
Many options are extremely technical, and refer internals, making it
difficult to translate usefully. This came up in discussion of e.g.
 #10949. If a message is not understood by translators (which are
typically end-users, not developers) they'll either translate it
literally, making it harder to understand instead of easier, with the
added drawback of the user no longer being able to google it.

Also the translation was only working for bitcoin-qt as with
the console programs, there is no translation backend. So it was
injecting never-used translation messages for bitcoin-cli, -tx.

For these reasons, stop translating options help completely. This should
not affect the output **in any way** except for bitcoin-qt when a
non-English language is configured in the locale.

This implements #10962.

Merge #13134: net: Add option `-enablebip61` to configure sending of BIP61 notifications
87fe292d89 doc: Mention disabling BIP61 in bips.md (Wladimir J. van der Laan)
fe16dd8226 net: Add option `-enablebip61` to configure sending of BIP61 notifications (Wladimir J. van der Laan)

Pull request description:

  This commit adds a boolean option `-peersendreject`, defaulting to `1`, that can be used to disable the sending of [BIP61](https://github.com/bitcoin/bips/blob/master/bip-0061.mediawiki) `reject` messages. This functionality has been requested for various reasons:

  - security (DoS): reject messages can reveal internal state that can be used to target certain resources such as the mempool more easily.

  - bandwidth: a typical node sends lots of reject messages; this counts against upstream bandwidth. Also the reject messages tend to be larger than the message that was rejected.

  On the other hand, reject messages can be useful while developing client software (I found them indispensable while creating bitcoin-submittx), as well as for our own test cases, so whatever the default becomes on the long run, IMO the functionality should be retained as option. But that's a discussion for later, for now it's simply a node operator decision.

  Also adds a RPC test that checks the functionality.

13c3a659c0 Qt/Bugfix: fix handling default wallet with no name (João Barbosa)

Pull request description:

  If one loads a wallet via RPC (`loadwallet w2`), then select w2, select back to the default wallet (which is an empty string), that default wallet cannot be access through the RPC console because the current code only points to the wallet endpoint if the wallet name is not empty.

  This is a quick fix that reenables accessing the default wallet in case an additional wallet has been loaded.

  Using "" for the default wallet may not be ideal in other cases and it may make more sense to change it at a deeper level (wallet.cpp). See discussion here which where the reasons for the current behaviour in master:

4e91820531 Make IsMine stop distinguishing solvable/unsolvable (Pieter Wuille)
6d714c3419 Make coincontrol use IsSolvable to determine solvability (Pieter Wuille)

Pull request description:

  Our current `IsMine` logic does several things with outputs:
  * Determine "spendability" (roughly corresponding to "could we sign for this")
  * Determine "watching" (is this an output directly or indirectly a watched script)
  * Determine invalidity (is this output definitely not legally spendable, detecting accidental uncompressed pubkeys in witnesses)
  * Determine "solvability" (would we be able to sign for this ignoring the fact that we may be missing some private keys).

  The last item (solvability) is mostly unrelated and only rarely needed (there is just one instance, inside the wallet's coin control logic). This PR changes that instance to use the separate `IsSolvable` function, and stop `IsMine` from distinguishing between solvable and unsolvable.

  As an extra, this also simplifies the `IsMine` logic and adds some extra checks (which wouldn't be hit unless someone adds already invalid scripts to their wallet).

Merge #13284: gui: fix visual "overflow" of amount input.
5f3cbde9de Increased max width of amount field to prevent number overflow bug. (Brandon Ruggles)

Pull request description:

  Fixes #13231.

  I was able to reproduce this bug within my own Fedora 27 VM. Following @jonasschnelli's advice, I first tried to change `setAlignment(Qt::AlignRight);` to `setAlignment(Qt::AlignLeft);`, however, I realized that this wouldn't fix the underlying overflow problem, as it would only make it easier to see the most significant digits under certain scenarios. The reason for the overflow is that Fedora uses plus and minus buttons on the Qt spin box class, rather than up and down arrows, which is what happens on **most** other operating systems. These plus and minus buttons take up more width, and therefore provide less space for text.

  The solution I went with was the second suggestion by @jonasschnelli, which was to just increase the maximum width of the amount box. After some experimentation, 240 seemed to be the smallest max width that would allow as many digits as one would want in the amount box without overflow, even with the plus and minus buttons in Fedora.

  Please let me know if there are any issues with this PR and I will work to fix them. Thank you!

c865ee1e73 Fix FreeBSD build by including utilstrencodings.h (Wladimir J. van der Laan)

Pull request description:

  `random.cpp` needs to explicitly include `utilstrencodings.h` to get `ARRAYLEN`. This fixes the FreeBSD build.

  This was broken in 84f41946b9 (#13236).

Merge #13063: Use shared pointer to retain wallet instance
80b4910f7d wallet: Use shared pointer to retain wallet instance (João Barbosa)

Pull request description:

  Currently there are 3 places where it makes sense to retain a wallet shared pointer:
   - `vpwallets`;
   - `interfaces::Wallet` interface instance - used by the UI;
   - wallet RPC functions - given by `GetWalletForJSONRPCRequest`.

  The way it is now it is possible to have, for instance, listunspent RPC and in parallel unload the wallet (once #13111 is merged) without blocking. Once the RPC finishes, the shared pointer will release the wallet.

  It is also possible to get all existing wallets without blocking because the caller keeps a local list of shared pointers.

  This is mostly relevant for wallet unloading.

  This PR replaces #11402.

Merge #13151: net: Serve blocks directly from disk when possible
0bf431870e net: Serve blocks directly from disk when possible (Wladimir J. van der Laan)

Pull request description:

  In `ProcessGetBlockData`, send the block data directly from disk if type MSG_WITNESS_BLOCK is requested. This is a valid shortcut as the on-disk format matches the network format.

  This is expected to increase performance because a deserialization and subsequent serialization roundtrip is avoided.

Merge #13011: Cache witness hash in CTransaction
fac1223a56 Cache witness hash in CTransaction (MarcoFalke)
faab55fbb1 Make CMutableTransaction constructor explicit (MarcoFalke)

Pull request description:

  This speeds up:
  * compactblocks (v2)
  * ATMP
  * validation and miner (via `BlockWitnessMerkleRoot`)
  * sigcache (see also unrelated #13204)
  * rpc and rest (nice, but irrelevant)

  This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.

Pull request description:

  It returns per block statistics about several things. It should be easy to add more if people think of other things to add or remove some if I went too far (but once written, why not keep it? EDIT: answer: not to test or maintain them).

  The currently available options are: minfee,maxfee,totalfee,minfeerate,maxfeerate,avgfee,avgfeerate,txs,ins,outs (EDIT: see updated list in the rpc call documentation)

  For the x axis, one can use height or block.nTime (I guess I could add mediantime if there's interest [EDIT: nobody showed interest but I implemented mediantime nonetheless, in fact there's no distinction between x or y axis anymore, that's for the caller to judge]).

  To calculate fees, -txindex is required.
