What is Bitcoin?
|
|
----------------
|
|
|
|
Bitcoin is an experimental new digital currency that enables instant payments to
|
|
anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate
|
|
with no central authority: managing transactions and issuing money are carried
|
|
out collectively by the network. Bitcoin Core is the name of open source
|
|
software which enables the use of this currency.
|
|
|
|
For more information, as well as an immediately useable, binary version of
|
|
the Bitcoin Core software, see https://www.bitcoin.org/en/download.

Development process
|
|
-------------------
|
|
|
|
Developers work in their own trees, then submit pull requests when they think
|
|
their feature or bug fix is ready.
|
|
|
|
If it is a simple/trivial/non-controversial change, then one of the Bitcoin
|
|
development team members simply pulls it.
|
|
|
|
If it is a *more complicated or potentially controversial* change, then the patch
|
|
submitter will be asked to start a discussion (if they haven't already) on the
|
|
[mailing list](http://sourceforge.net/mailarchive/forum.php?forum_name=bitcoin-development).
|
|
|
|
The patch will be accepted if there is broad consensus that it is a good thing.
|
|
Developers should expect to rework and resubmit patches if the code doesn't
|
|
match the project's coding conventions (see [doc/coding.md](doc/coding.md)) or are
|
|
controversial.
|
|
|
|
The `master` branch is regularly built and tested, but is not guaranteed to be
|
|
completely stable. [Tags](https://github.com/bitcoin/bitcoin/tags) are created
|
|
regularly to indicate new official, stable release versions of Bitcoin.
|
|
|
|
Testing
|
|
-------
|
|
|
|
Testing and code review is the bottleneck for development; we get more pull
|
|
requests than we can review and test on short notice. Please be patient and help out by testing
|
|
other people's pull requests, and remember this is a security-critical project where any mistake might cost people
|
|
lots of money.
|
|
|
|
### Automated Testing
|
|
|
|
Developers are strongly encouraged to write unit tests for new code, and to
|
|
submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: `make check`
|
|
|
|
Every pull request is built for both Windows and Linux on a dedicated server,
|
|
and unit and sanity tests are automatically run. The binaries produced may be
|
|
used for manual QA testing — a link to them will appear in a comment on the
|
|
pull request posted by [BitcoinPullTester](https://github.com/BitcoinPullTester). See https://github.com/TheBlueMatt/test-scripts
|
|
for the build/test scripts.
|
|
|
|
### Manual Quality Assurance (QA) Testing
|
|
|
|
Large changes should have a test plan, and should be tested by somebody other
|
|
than the developer who wrote the code.
|
|
See https://github.com/bitcoin/QA/ for how to create a test plan.
|
|
|
|
Translations
|
|
------------
|
|
|
|
Changes to translations as well as new translations can be submitted to
|
|
[Bitcoin Core's Transifex page](https://www.transifex.com/projects/p/bitcoin/).
|
|
|
|
Translations are periodically pulled from Transifex and merged into the git repository. See the
|
|
[translation process](doc/translation_process.md) for details on how this works.
|
|
|
|
**Important**: We do not accept translation changes as GitHub pull requests because the next
|
|
pull from Transifex would automatically overwrite them again.
|
|
|
|
Translators should also subscribe to the [mailing list](https://groups.google.com/forum/#!forum/bitcoin-translators).

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.
