Print to console by default when not run with -daemon #13004

practicalswift · 2018-04-17T08:03:39Z

Cherry-picked ef6fa1c from the "up for grabs" PR: "Smarter default behavior for -printtoconsole" (#12689).

See previous review in #12689.

Printing to the debug log file can be disabled with -nodebulogfile

@ryanofsky Could you re-review here.

practicalswift · 2018-04-17T08:13:52Z

Previous utACK:ers @meshcollider and @jnewbery might want to take a look at this one too? :-)

concept ACK

Whoa - good catch to move this inside the if (fPrintToDebugLog)

Thanks for reviving this, tested ACK 6a3b0d3:

src/bitcoind -regtest works as expected, now prints logging output
src/bitcoind -regtest -noprinttoconsole successfully silences logging output
src/bitcoind -regtest -daemon successfully silences logging output

        self.setup_clean_chain = True

+    def relative_log_path(self, name):
+        return os.path.join(self.nodes[0].datadir, "regtest", name)


nit: IIRC datadir is absolute, so the relative in the method name is confusing.

Nit: Could use the identical and more clear "remove", since unlink seems to be some unix specific thing, but we also run the tests on windows.

utACK 6a3b0d3. Some naming nits in tests.

Hmm, won't it print these newlines even if fPrintToDebugLog ends up being false?

GUI programs should not print to the console unnecessarily. For example, when launched by the window manager, the output might end up in the X session log file, resulting in duplicate logging. On Windows, it is pointless as well because bitcoin-qt isn't a console application. This same mechanism is used to set `-server` to true by default for bitcoind: https://github.com/bitcoin/bitcoin/blob/master/src/bitcoind.cpp#L116 (fixes #13004) Tree-SHA512: 24ae460d9d97130a063f7bf7fa6da1e6cc46643a94ea0827aa64d0f4a80647e5e7394695b24ea0f49a147a1fa07329659d224f04511fc24b97a9869d1c29b890

It's overly noisy, and not useful to have the bitcoin nodes log to stdout in the functional tests. In case of troubleshooting the `debug.log` files can be inspected. This was the behavior before bitcoin#13004.

bitcoin#13004 changed the default behavior for printtoconsole but this has not been reflected in the command line help. This fixes the description of -printtoconsole to reflect this change, and also provides the user with missing information on how to explicitly disable logging to debug.log. At present I have made the latter update to two separate places (-printtoconsole and -debuglogfile) because a user looking for information on how to disable logging is probably going to look in the "Debugging/Testing Options" section. Moving -debuglogfile from the "General" options category to the "Debugging/Testing" section could potentially remove the need for this redundancy but may be out of the scope of this PR.
