By default, libc will print fatal errors to /dev/tty instead of stderr. Adding the LIBC_FATAL_STDERR_ to the environment variables allows us to catch libc errors in stderr and test for them.

If `nodes[0]` spends the associated UTXO during any of its sends later, the watchonly test will fail, as `nodes[3]` now has insufficient funds.

2018-05-03Merge #12729: Get rid of ambiguous OutputType::NONE valueWladimir J. van der Laan
1e46d8a Get rid of ambiguous OutputType::NONE value (Russell Yanofsky) Pull request description: Based on suggestion by @sipa https://github.com/bitcoin/bitcoin/pull/12119#issuecomment-357982763 After #12119, the NONE output type was overloaded to refer to either an output type that couldn't be parsed, or to an automatic change output mode. This change drops the NONE enum and uses a simple bool to indicate parse failure, and a new CHANGE_AUTO enum to refer the change output type. This change is almost a pure refactoring except it makes RPCs reject empty string ("") address types instead of treating them like they were unset. This simplifies the parsing code a little bit and could prevent RPC usage mistakes. It's noted in the release notes. Follows up #12408 by @MarcoFalke Followups for future PRs: - [ ] Add explicit support for specifying "auto" in `ParseOutputType` as suggested by promag and sipa: https://github.com/bitcoin/bitcoin/pull/12729#issuecomment-374799567 and https://github.com/bitcoin/bitcoin/pull/12729#discussion_r175969481 - [ ] Add wallet `AddressChangeType` method to complement `TransactionChangeType`: https://github.com/bitcoin/bitcoin/pull/12729#discussion_r175969618.

It only disables some RPC commands when large work forks are detected. Nothing else is affected by safe mode. It seems that very few people would be affected by safe mode.

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 P2SH change is pretty straightforward -- there was only one historical block on mainnet that violated the rule, so I carved out an exception to it, similar to the way we have exceptions for the BIP30 violators. The segwit change is not entirely as clear. The code changes themselves are relatively straightforward: we can just always turn on SCRIPT_VERIFY_WITNESS whenever P2SH is active. However conceptually, this amounts to splitting up BIP141 into two parts, the part that implements new script rules, and the part that handles witness commitments in blocks. Arguably though the script rules are really defined in BIP 143 anyway, and so this really amounts to backdating BIP 143 -- script rules for v0 segwit outputs -- back to genesis. So maybe conceptually this isn't so bad... I don't feel strongly about this change in either direction; I started working on it because I was searching for a way to simplify the way we understand and implement the consensus rules around segwit, but I'm not yet sure whether I think this achieves anything toward that goal. ping @TheBlueMatt Tree-SHA512: 73551d4a983eb9792c7ac67f56005822528ac4d1fd52c27cee6d305ebee953f69687ef4ddee8bdc0fec77f77e6b5a9d669750793efee54c076533a095e233042

2018-04-17[wallet] [rpc] Deprecate account RPC methodsJohn Newbery
All account RPC methods are now deprecated and can only be called if bitcoind has been started with the -deprecatedrpc=accounts switch. Affected RPC methods are: - getaccount - getaccountaddress - getaddressesbyaccount - getreceivedbyaccount - listaccouts - listreceivedbyaccount - move - setaccount

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. Thoughts?
