This is a pointless feature. As it only works when all private keys are in one place, it's useless compared to single key outputs (P2PK, P2PKH, P2WPKH, P2SH-P2WPKH), and worse in terms of space, cost, UTXO size, and ability to test (due to lack of address format for them). Furthermore, they are problematic in that producing a list of all `scriptPubKeys` we accept is not tractable (it involves all combinations of all public keys that are ours). In further wallet changes I'd like to move to a model where all scriptPubKeys that are treated as ours are explicit, rather than defined by whatever keys we have. The current behavior of the wallet is very hard to model in such a design, so I'd like to get rid of it. I think there are two options: * Remove it entirely (do not ever accept bare multisig outputs as ours, unless watched) * Only accept bare multisig outputs in situations where the P2SH version of that output would also be acceptable This PR implements the first option. The second option was explored in #12874. Tree-SHA512: 917ed45b3cac864cee53e27f9a3e900390c576277fbd6751b1250becea04d692b3b426fa09065a3399931013bd579c4f3dbeeb29d51d19ed0c64da75d430ad9a

Such outputs can still be watched, and signed for, but they aren't treated as valid payments. That means they won't cause transactions to appear in listtransactions, their outputs to be shown under listunspent, or affect balances.

Seems providing at least minimal visibility to the failure is a good practice. The only remaining ignored state is in LoadExternalBlockFile, where logging would likely be spammy.

This approach is (more or less) supported by `boost::program_options::detail::config_file_iterator` -- when it sees a `[testnet]` section with `port=5`, it will treat that the same as "testnet.port=5". So `[testnet] port=5` (or `testnet.port=5` without the section header) in bitcoin.conf and `-testnet.port=5` on the command line. The other aspect to this question is possibly limiting some options so that there is no possibility of accidental cross-contamination across networks. For example, if you're using a particular wallet.dat on mainnet, you may not want to accidentally use the same wallet on testnet and risk reusing keys. I've set this up so that the `-addnode` and `-wallet` options are `NETWORK_ONLY`, so that if you have a bitcoin.conf: wallet=/secret/wallet.dat upnp=1 and you run `bitcoind -testnet` or `bitcoind -regtest`, then the `wallet=` setting will be ignored, and should behave as if your bitcoin.conf had specified: upnp=1 [main] wallet=/secret/wallet.dat For any `NETWORK_ONLY` options, if you're using `-testnet` or `-regtest`, you'll have to add the prefix to any command line options. This was necessary for `multiwallet.py` for instance. I've left the "default" options as taking precedence over network specific ones, which might be backwards. So if you have: maxmempool=200 [regtest] maxmempool=100 your maxmempool will still be 200 on regtest. The advantage of doing it this way is that if you have `[regtest] maxmempool=100` in bitcoin.conf, and then say `bitcoind -regtest -maxmempool=200`, the same result is probably in line with what you expect... The other thing to note is that I'm using the chain names from `chainparamsbase.cpp` / `ChainNameFromCommandLine`, so the sections are `[main]`, `[test]` and `[regtest]`; not `[mainnet]` or `[testnet]` as might be expected.

When a -nofoo option is seen, instead of adding it to a separate set of negated args, set the arg as being an empty vector of strings. This changes the behaviour in some ways: - -nofoo=0 still sets foo=1 but no longer treats it as a negated arg - -nofoo=1 -foo=2 has GetArgs() return [2] rather than [2,0] - "foo=2 \n -nofoo=1" in a config file no longer returns [2,0], just [0] - GetArgs returns an empty vector for negated args

This uses an approach by @theuni that relies on `make` as the mechanism for distributing tests over processes (through `-j`). For every test .cpp file, we search for `BOOST_FIXTURE_TEST_SUITE` or `BOOST_AUTO_TEST_SUITE`, and then invoke the test binary for just that suite (using `-t`). The (verbose) output is stored in a temporary file, and only shown in the case of failure. Some makefile reshuffling is necessary to avoid trying to run tests from `src/test/test_bitcoin.cpp` for example, which contains framework/utility code but no real tests. Finally, order the Travis jobs from slow to fast (apart from the arm/doc job which goes first, for fast failure). This should help reducing the total wall clock time before opening a PR and finishing Travis, in case where not all jobs are started simultaneously. This is an alternative to #12831.

(Evan Klitzke) 4f872b2450 Add additional tests for GetBoolArg() (Evan Klitzke) Pull request description: This change explicitly enable tracking negated options in the option parser. A negated option is one passed with a `-no` prefix. For example, `-nofoo` is the negated form of `-foo`. Negated options were originally added in the 0.6 release. The change here allows code to explicitly distinguish between cases like `-nofoo` and `-foo=0`, which was not possible previously. The option parser does not have any changed semantics as a result of this change, and existing code will parse options just as it did before. The motivation for this change is to provide a way to disable options that are otherwise not boolean options. For example, the `-debuglogfile` option is normally interpreted as a string, where the value is the log file name. With this change a user can pass in `-nodebuglogfile` and the code can see that it was explicitly negated, and use that to disable the log file. This change originally split out from #12689.

This commit adds tracking for negated arguments. This change will be used in a future commit that allows disabling the debug.log file using -nodebuglogfile.
2018-03-27Add additional tests for GetBoolArg()Evan Klitzke
This is meant to be an intermediate commit to prove that the next does not introduce any changes in the semantics of boolean option parsing.

1f45e21 scripted-diff: Convert 11 enums into scoped enums (C++11) (practicalswift) Pull request description: Rationale (from Bjarne Stroustrup's ["C++11 FAQ"](http://www.stroustrup.com/C++11FAQ.html#enum)): > > The enum classes ("new enums", "strong enums") address three problems with traditional C++ enumerations: > > * conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer. > * conventional enums export their enumerators to the surrounding scope, causing name clashes. > * the underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible. > > The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).

2018-03-22Merge #12630: Provide useful error message if datadir is not writable.Wladimir J. van der Laan
8674e74 Provide relevant error message if datadir is not writable. (murrayn) Pull request description: If the --datadir exists, but is not writable, the current error message on startup is 'Cannot obtain a lock on data directory foo. Bitcoin Core is probably already running.' This is misleading. I believe this PR addresses #11668, although the issue is not Windows-specific.
