* Multi-version snapshot support
* rustfmt
* Remove CLI options and runtime support for selection output snapshot version.
Address some clippy complaints.
* Muzzle clippy type complexity warning.
Despite clippy's suggestion, it is not currently possible to create type aliases
for traits and so everything within the 'Box<...>' cannot be type aliased.
This then leaves creating full blown traits, and either implementing
said traits by closure (somehow) or moving the closures into new structs
implementing said traits which seems a bit of a palaver.
Alternatively it is possible to define and use the type alias 'type ResultBox<T> = Result<Box<T>>'
which does seems rather pointless and not a great reduction in complexity but is enough to keep clippy happy.
In the end I simply went with squelching the clippy warning.
* Remove now unused Serialize/Deserialize trait implementations for AccountStorageEntry and AppendVec
* refactor versioned de/serialisers
* rename serde_utils to serde_snapshot
* move call to accounts_db.generate_index() back down to context_accountsdb_from_stream()
* update version 1.1.1 to 1.2.0
remove nested use of serialize_bytes
* cleanups
* Add back measurement of account storage entry serialization.
Remove construction of Vec and HashMap temporaries during serialization.
* consolidate serialisation test cases into serde_snapshot.
clean up leakage of implementation details in serde_snapshot.
* move short term / legacy snapshot code into child module
* add serialize_iter_as_tuple
* preliminary integration of following commit

Confine snapshot 1.1 relic to versioned codepath
* refactored serde_snapshot, rustfmt
legacy accounts_db format now "owns" both leading u64s, legacy bank_rc format has none
* reduce type complexity (clippy)

Building
1. Install rustc, cargo and rustfmt.
$ curl https://sh.rustup.rs -sSf | sh
$ source $HOME/.cargo/env
$ rustup component add rustfmt
If your rustc version is lower than 1.39.0, please update it:
$ rustup update
On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, etc. On Ubuntu:
$ sudo apt-get update
$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang
2. Download the source code.
$ git clone https://github.com/solana-labs/solana.git
$ cd solana
3. Build.
$ cargo build
4. Run a minimal local cluster.
$ ./run.sh
Testing
Run the test suite:
$ cargo test
Starting a local testnet
Start your own testnet locally, instructions are in the online docs.
Accessing the remote testnet
testnet- public stable testnet accessible via devnet.solana.com. Runs 24/7
Benchmarking
First install the nightly build of rustc. cargo bench requires use of the
unstable features only available in the nightly build.
$ rustup install nightly
Run the benchmarks:
$ cargo +nightly bench
Release Process
The release process for this project is described here.
Code coverage
To generate code coverage statistics:
$ scripts/coverage.sh
$ open target/cov/lcov-local/index.html
Why coverage? While most see coverage as a code quality metric, we see it primarily as a developer productivity metric. When a developer makes a change to the codebase, presumably it's a solution to some problem. Our unit-test suite is how we encode the set of problems the codebase solves. Running the test suite should indicate that your change didn't infringe on anyone else's solutions. Adding a test protects your solution from future changes. Say you don't understand why a line of code exists, try deleting it and running the unit-tests. The nearest test failure should tell you what problem was solved by that code. If no test fails, go ahead and submit a Pull Request that asks, "what problem is solved by this code?" On the other hand, if a test does fail and you can think of a better way to solve the same problem, a Pull Request with your solution would most certainly be welcome! Likewise, if rewriting a test can better communicate what code it's protecting, please send us that patch!
