Merge #10831: Batch flushing operations to the walletdb during top up and increase keypool size. 
b0e8e2d Print one log message per keypool top-up, not one per key. (Gregory Maxwell)
41dc163 Increase wallet default keypool size to 1000. (Gregory Maxwell)
30d8f3a Pushdown walletdb though CWallet::AddKeyPubKey to avoid flushes. (Gregory Maxwell)
3a53f19 Pushdown walletdb object through GenerateNewKey/DeriveNewChildKey. (Gregory Maxwell)

Pull request description:

  This carries the walletdb object from top-up through GenerateNewKey/DeriveNewChildKey/CWallet::AddKeyPubKey, which allows us to avoid the flush on destruction until the top up finishes instead of flushing the wallet for every key.

  This speeds up adding keys by well over 10x on my laptop (actually something like 17x), I wouldn't be surprised if it were an even bigger speedup on spinning rust.

  Then it increases the keypool size to 1000. I would have preferred to use 10,000 but in the case where the user creates a new wallet and then turns on encryption it seems kind of dumb to have >400KB of marked-used born unencrypted keys just laying around.

  (Thanks to Matt for cluesticking me on how to bypass the crypter spaghetti)

Build Status

What is Bitcoin?

Bitcoin is an experimental 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://bitcoin.org/en/download, or read the original whitepaper.

License

Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Bitcoin Core.

The contribution workflow is described in CONTRIBUTING.md.

The developer mailing list should be used to discuss complicated or controversial changes before working on a patch set.

Developer IRC can be found on Freenode at #bitcoin-core-dev.

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. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The Travis CI system makes sure that every pull request is built for Windows, Linux, and OS X, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process 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.
