Prototype directory
The contents of the prototype directory is the result of
consolidating several small & independent repos. Originally, each
small was a separate prototype/quick hack for experimentation
purposes. The code is preserved here for use as:
- Examples of what not to do ... the code is a bit ugly, after all. ^_^
- Some examples of what to do when prototyping in Erlang. For example, "Let it crash" style coding is so nice to hack on quickly.
- Some code might actually be reusable, as-is or after some refactoring.
The prototype code here is not meant for long-term use or maintenance. We are unlikely to accept changes/pull requests for adding large new features or to build full Erlang/OTP applications using this code only.
However, pull requests for small changes, such as support for newer Erlang versions (e.g., Erlang 17), will be gladly accepted. We will also accept fixes for bugs in the test code.
The corfurl prototype
The corfurl code is a mostly-complete complete implementation of the
CORFU server & client specification. More details on the papers about
CORFU are mentioned in the corfurl/docs/corfurl.md file.
This code contains a QuickCheck + PULSE test. If you wish to use it,
please note the usage instructions and restrictions mentioned in the
README.md file.
The demo-day-hack prototype
This code in the demo-day-hack is expected to remain static,
as an archive of past "Demo Day" work.
See the top-level README.md file for details on work to move
much of this code out of the prototype directory and into real
use elsewhere in the repo.
The tango prototype
A quick & dirty prototype of Tango on top of the prototype/corfurl
CORFU implementation. The implementation is powerful enough (barely)
to run concurrently on multiple Erlang nodes. See its README.md
file for limitations, TODO items, etc.
The chain-manager prototype
This is a very early experiment to try to create a distributed "rough consensus" algorithm that is sufficient & safe for managing the order of a Chain Replication chain, its members, and its chain order.
Unlike the other code projects in this repository's prototype
directory, the chain management code is still under active
development. However, the chain manager code here in the prototype
subdirectory will remain frozen in time.
Efforts in April 2015 have moved the chain manager code to the "top level"
of the repository. All new work is being merged weekly into the master
branch, see src/machi_chain_manager1.erl and related source at the top of
the repo.
