Gavin Andresen 6f8730752c Treat non-final transactions as non-standard 
At least one service that accepted zero-confirmation transactions
was vulnerable because an attacker could send a transaction
with a lock time far in the future, and then have plenty of time in
which to get a double-spend mined (perhaps from a miner who wasn't
on the network when the first transaction was broadcast).

That is a variation on the "Finney attack". We still don't
recommend anybody accept 0-confirmation transactions as final
payment for anything. This change keeps non-final transactions
from appearing in the wallet, and, assuming most of the network
accepts this change, will prevent them from being relayed until
they are final.

Bitcoin integration/staging tree

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 they don't match the project's coding conventions (see coding.txt) or are controversial.

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are regularly created 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. Please be patient and help out, 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 for the core code are in src/test/ To compile and run them: cd src; make -f makefile.linux test

Unit tests for the GUI code are in src/qt/test/ To compile and run them: qmake BITCOIN_QT_TEST=1 -o Makefile.test bitcoin-qt.pro make -f Makefile.test ./Bitcoin-Qt

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 from '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.
