init: Use InitError for all errors in bitcoind/qt #16366

maflcko · 2019-07-10T13:25:47Z

Using the same InitError for startup error in the daemon and the gui makes it possible to run the tests with the gui again:

BITCOIND=bitcoin-qt ./test/functional/test_runner.py feature_includeconf feature_config_args

utACK fa6647a. I wonder if it'd be possible to run tests with BITCOIND=bitcoin-qt QT_QPA_PLATFORM=minimal on travis to catch more regressions.

hebasto · 2019-07-10T16:49:46Z

Concept ACK.

Usually, running self-compiled bitcoin-qt on Linux Mint 19.1 I get a message:

$ ./src/qt/bitcoin-qt
qt5ct: using qt5ct plugin

So local run tests on my environment returns errors:

InitError was supposed to only be called from the AppInit* functions, to make sure it isn't called before the appropriate listeners are installed. It seems I lost track of how the initialization process works though.

ryanofsky · 2019-07-11T15:41:05Z

to make sure it isn't called before the appropriate listeners are installed

@laanwj what are "listeners" here? I don't understand what this could be referring to.

laanwj · 2019-07-11T15:54:24Z

@laanwj what are "listeners" here? I don't understand what this could be referring to.

uiInterface signal listeners etc

maflcko · 2019-07-11T16:06:54Z

In bitcoind.cpp, I only modify the AppInit function, so the change is obviously correct there.

However, the gui uses a self-brewed AppInit*, I think. One of the first things in GuiMain is to // Subscribe to global signals from core. So it should be fine as well.

I'd presume it would be more difficult to rewrite the Gui init to call the same AppInit function as bitcoind does, so I'd rather not do that.

ACK fa6647a again. No changes since last review, I just dug into this a little more. I have some suggestions and questions below, but they are not too important, so feel free to ignore them.

src/qt/bitcoin.cpp

Also, remove unused <boost/thread.hpp> include (and others)

Avoids GUI code calling a node function, and having to live in the same process as g_ui_signals and uiInterface global variables.

hebasto · 2019-07-13T12:10:47Z

ACK fa6f402

Tested on Linux Mint 19.1 with system Qt 5.9.5.

The "using qt5ct plugin" message that is printed to stderr by qt5ct can be suppressed by the following environment variable:

QT_LOGGING_RULES="qt5ct.debug=false"

Using this knowledge, feature_includeconf.py passed:

$ BITCOIND=bitcoin-qt QT_LOGGING_RULES="qt5ct.debug=false" ./test/functional/test_runner.py feature_includeconf
Temporary test directory at /tmp/test_runner_₿_🏃_20190713_150236

feature_includeconf.py | ✓ Passed  | 10 s

ALL                    | ✓ Passed  | 10 s (accumulated)

And feature_config_args.py passed too:

$ BITCOIND=bitcoin-qt QT_LOGGING_RULES="qt5ct.debug=false" ./test/functional/test_runner.py feature_config_args
Temporary test directory at /tmp/test_runner_₿_🏃_20190713_150609

@MarcoFalke
Could you add QT_LOGGING_RULES="qt5ct.debug=false" to the OP?

maflcko · 2019-07-15T13:24:59Z

Could you add QT_LOGGING_RULES="qt5ct.debug=false" to the OP?

This is specific to your environment. If I add that, I would also have to add XDG_SESSION_TYPE=x11, because someone might be running on Wayland with Gnome and get the Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome.)

utACK fa6f402. Only changes since last review are removing more includes and adding Node::initError method to avoid accessing node InitError function and global variables from GUI code.

maflcko · 2019-07-22T12:25:43Z

This pull will be merged some time this week, unless there are objections.
