Development tips and tricks
---------------------------

**compiling for debugging**

Run configure with the --enable-debug option, then make. Or run configure with
CXXFLAGS="-g -ggdb -O0" or whatever debug flags you need.

**debug.log**

If the code is behaving strangely, take a look in the debug.log file in the data directory;
error and debugging messages are written there.

The -debug=... command-line option controls debugging; running with just -debug will turn
on all categories (and give you a very large debug.log file).

The Qt code routes qDebug() output to debug.log under category "qt": run with -debug=qt
to see it.

**testnet and regtest modes**

Run with the -testnet option to run with "play bitcoins" on the test network, if you
are testing multi-machine code that needs to operate across the internet.

If you are testing something that can run on one machine, run with the -regtest option.
In regression test mode, blocks can be created on-demand; see qa/rpc-tests/ for tests
that run in -regtest mode.

**DEBUG_LOCKORDER**

Bitcoin Core is a multithreaded application, and deadlocks or other multithreading bugs
can be very difficult to track down. Compiling with -DDEBUG_LOCKORDER (configure
CXXFLAGS="-DDEBUG_LOCKORDER -g") inserts run-time checks to keep track of which locks
are held, and adds warnings to the debug.log file if inconsistencies are detected.

Pull Request Terminology
------------------------

Concept ACK - Agree with the idea and overall direction, but haven't reviewed the code changes or tested them.

utACK (untested ACK) - Reviewed and agree with the code changes but haven't actually tested them.

Tested ACK - Reviewed the code changes and have verified the functionality or bug fix.

ACK - A loose ACK can be confusing. It's best to avoid them unless it's a documentation/comment only change in which case there is nothing to test/verify; therefore the tested/untested distinction is not there.

NACK - Disagree with the code changes/concept. Should be accompanied by an explanation.
