127b4608e9 test: Check if specified config file cannot be opened (nthumann)
6bb54708e6 util: Check if specified config file cannot be opened (nthumann)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/22612.
When running e.g. `./src/bitcoind -datadir=/tmp/bitcoin -regtest -conf=/tmp/bitcoin/regtest/bitcoin.conf` and the specified config cannot be opened (doesn't exist, permission denied, ...), the initialization silently uses the default config.
As voidburn already noted:
> I can't think of a situation in which a config file is specified explicitly (in the startup options, as per service unit linked above), but inaccessible, where the fail condition should be to keep booting using defaults instead.
With this patch applied, the initialization will fail immediately, if the specified config file cannot be opened. If no config file is explicitly specified, the behavior is unchanged. This not only affects `bitcoind`, but also `bitcoin-cli` and `bitcoin-qt`.
In the example below the datadir is accessible, but the config file is not due to insufficient permissions:
```
$ ./src/bitcoind -datadir=/tmp/bitcoin -regtest --debug=1 -conf=/tmp/bitcoin/regtest/bitcoin.conf
Error: Error reading configuration file: specified config file "/tmp/bitcoin/regtest/bitcoin.conf" could not be opened.
```

Pull request description:
This PR adds a DNS seed to the regtest chain params to enable testing the DNS seed querying logic of `CConnman::ThreadDNSAddressSeed` and relevant startup parameters. Adds coverage for the changes in #22013 (and then some).
The main behavioral change to bitcoind is that this PR disallows starting up with conflicting parameters for `-dnsseed` and `-forcednsseed`.
The tests include:
* parameter interactions of different combinations of `-connect`, `-dnsseed` and `-forcednsseed`
* the delay before querying DNS seeds depending on how many addresses are in the addrman
* the behavior of `-forcednsseed`
* skipping DNS querying if we have outbound full relay connections & not block-relay-only connections
Huge props to mzumsande for identifying the timing technique for testing successful connections before running `ThreadDNSAddressSeed` 🙌🏽

This commit introduces a DNS seed to the regest chain params in order to add
coverage to the DNS querying logic.
The first test checks that we do not query DNS seeds if we are able to
succesfully connect to 2 outbound connections. Since we participate in ADDR
relay with those connections, including sending a GETADDR message during the
VERSION handshake, querying the DNS seeds is unnecessary.

This prevents the node from trying to connect to random IPs on the internet
while running the functional tests. Exceptions are added when required for
the test to pass.
Every (sub)test in the framework assumes the node is running, except for
the (sub)tests in this file. Remove that confusion by stopping the node
at the start of every subtest, instead of at the end.
ff44cae279 test: Change feature_config_args.py not to rely on strange regtest=0 behavior (Russell Yanofsky)
Pull request description:
Update test to simply generate a normal mainnet configuration file instead of using a crazy setup where a regtest=1 config file using an includeconf in the [regtest] section includes another config file that specifies regtest=0, retroactively switching the network to mainnet.
This setup was fragile and only worked because the triggered InitError happened early enough that none of the ignored [regtest] options mattered (only affecting log output).
This change was originally made as part of #17493

c1585bca8d test: Get rid of default wallet hacks (Russell Yanofsky)
ed3acda33b test, refactor: add default_wallet_name and wallet_data_filename variables (Russell Yanofsky)
Pull request description:
Changes:
- Get rid of setup_nodes (`-wallet`, `-nowallet`, `-disablewallet`) argument rewriting
- Get rid of hardcoded wallet `""` names and `-wallet=""` args
Motivation:
- Simplify test framework behavior so it's easier to write new tests without having arguments mangled by the framework
- Make tests more readable, replacing unexplained `""` string literals with `default_wallet_name` references
- Make it trivial to update default wallet name and wallet data filename for sqlite #19077 testing
- Stop relying on `-wallet` arguments to create wallets, so it is easy to change `-wallet` option in the future to only load existing wallets not create new ones (to avoid accidental wallet creation, and encourage use of wallet encryption and descriptor features)

Update test to simply generate a normal mainnet configuration file instead of
using a crazy setup where a regtest=1 config file using an includeconf in the
[regtest] section includes another config file that specifies regtest=0,
retroactively switching the network to mainnet.
This setup was fragile and only worked because the triggered InitError happened
early enough that none of the ignored [regtest] options mattered (only
affecting log output).
Building with -Wunreachable-code-loop-increment causes a warning
due to always returning on the first iteration of the loop that
outputs errors on invalid args.
Collect all errors, and output them in a single error message
after the loop completes, resolving the warning and avoiding
popup hell by outputting a seperate message for each error.

1abcecc40c Tests: Use self.chain instead of 'regtest' in almost all current tests (Jorge Timón)
Pull request description:
Simply avoiding the hardcoded string in more places for consistency.
It can also allow for more easily reusing tests for other chains other than regtest.
Separated from #8994 .
Continues #16509 .
It is still not complete (ie to be complete, we need the -chain parameter in #16680 and make whether acceptnonstdtxs is allowed for that chain or not customizable for regtest [or for custom chains like in #8994 ] ). But while being incomplete like #16509 , it's quite simple to review and another step forward IMO.

Of course, testnet policy remains unchanged to allow propagation of non-standard txs.

Pull request description:
Python 3.4 is EOL after March 2019, so switch to 3.5. See https://devguide.python.org/#status-of-python-branches
This pull does the following in a bunch of commits:
* scripted diff to use the `bytes::hex()` method in place of previous wrappers (`b2x`, `bytes_to_hex_str`, `hexlify`, ...)
* Update the build system (gitian and travis) to remove python2.7 and replace it with python3.5
* Another scripted-diff to remove brackets after `assert`. This is unrelated to the python3.5 switch, but a stylistic commit, so probably not worth to split up. The motivation behind it is to avoid asserting on data structures (such as tuples of length one), which never fails:
```py
>>> assert(False,) # with brackets
>>> assert False, # without brackets
SyntaxError: invalid syntax
>>> assert False # proper assertion
AssertionError
```
* And then a final scripted diff to update the copyright headers in the `test` subfolder, since I touched most of the files anyway and it wouldn't make sense to split this commit out into a separate pull.

1. Fix lack of warning by collecting all section names by moving
m_config_sections.clear() to ArgsManager::ReadConfigFiles().
2. Add info(file name, line number) to warning message.
3. Add a test code to confirm this situation.
3. Do clear() in ReadConfigString().
In the config file, sections are specified by square bracket pair "[]"$,
or included in the option name itself which separated by a period"(.)".
Typicaly, [testnet] is not a correct section name and specified options
in that section are ignored but user cannot recognize what is happen.
So, add some log/stderr-warning messages if unrecognized section names
are present in the config file after checking section only args.
