Felix Lange 90cd8ae9f2 rpc/api: don't crash for unknown blocks
Most eth RPC calls that work with blocks crashed when the block was not
found because they called Hash on a nil block. This is a regression
introduced in cdc2662c40 (#1779).

While here, remove the insane conversions in get*CountBy*. There is no
need to construct a complete BlockRes and converting
int->int64->*big.Int->[]byte->hexnum->string to format the length of a
slice as hex.

API Reference Gitter

Automated development builds

The following builds are build automatically by our build servers after each push to the develop branch.

Building the source

For prerequisites and detailed build instructions please read the Installation Instructions on the wiki.

Building geth requires two external dependencies, Go and GMP. You can install them using your favourite package manager. Once the dependencies are installed, run

make geth

Executables

Go Ethereum comes with several wrappers/executables found in the cmd directory:

Command
geth Ethereum CLI (ethereum command line interface client)
bootnode runs a bootstrap node for the Discovery Protocol
ethtest test tool which runs with the tests suite: /path/to/test.json > ethtest --test BlockTests --stdin.
evm is a generic Ethereum Virtual Machine: evm -code 60ff60ff -gas 10000 -price 0 -dump. See -h for a detailed description.
disasm disassembles EVM code: `echo "6001"
rlpdump prints RLP structures

Command line options

geth can be configured via command line options, environment variables and config files.

To get the options available:

geth help

For further details on options, see the wiki

Contribution

If you'd like to contribute to go-ethereum please fork, fix, commit and send a pull request. Commits who do not comply with the coding standards are ignored (use gofmt!). If you send pull requests make absolute sure that you commit on the develop branch and that you do not merge to master. Commits that are directly based on master are simply ignored.

See Developers' Guide for more details on configuring your environment, testing, and dependency management.
