Tagion

👋 Welcome to the Tagion project!

Tagion is a decentralized ledger for creating high volume transaction. It differs from blockchain based ledgers in that it uses a hashgraph as the consensus mechanism and a database based on a merkletree (DART) to store the bills of the system. Thus it does not need to record the entire transaction history to maintain integrity, only the state of world is recorded.

Setup steps & preflight checks

  1. First of all please be sure that you have everything, command You can run the following commands, if you are using arch, nix or ubuntu
  • Ubuntu
apt-get install git autoconf build-essential libtool dub cmake

Download a D compiler ldc or dmd

  • LLVM D compiler - ldc2 (v1.36.0)
wget https://github.com/ldc-developers/ldc/releases/download/v1.36.0/ldc2-1.36.0-linux-x86_64.tar.xz
tar xf ldc2-1.36.0-linux-x86_64.tar.xz
export PATH="path-to-ldc2/ldc2-1.34.0-linux-x86_64/bin:$PATH"
  • Reference D compiler - dmd (v2.106.1)
wget https://downloads.dlang.org/releases/2.x/2.106.1/dmd.2.106.1.linux.tar.xz
tar xf dmd.2.106.1.linux.tar.xz
export PATH="path-to-dmd2/dmd2/linux/bin64:$PATH"
  • Arch
pacman -Syu git make autoconf gcc libtool dlang cmake
  • Nix
nix develop
  1. Verify that the binaries are available and check their version (comments showing versions used as of writing)
ldc2 --version # LDC - the LLVM D compiler (1.36.0): ...
dmd --version # v2.106.1
  1. Cloning tagion repo
git clone [email protected]:tagion/tagion.git

Compiling

  1. Running tests
make test
  1. Compiling binaries
make tagion
make install
# Will install to dir specified by INSTALL=/path/to/dir
# This directory should also be in your PATH variable
# such that you can use the tools from you shell
  1. General info about build flow
# Help info
make help
# or
make help-<topic>

# Info about environment variables
make env
# or
make env-<topic>
  1. Compilation options, can be specified on the commandline or in a local.mk in the project root

Notice that if you choose to compile with ldc there is a bug which means that the unittests wont run.

# Showing the default values
ONETOOL=1 # ALL tools linked in to a single executable
          # and individual tools are symbolic links to that binary
DC=       # D compiler to use, default will try to pick between dmd and ldc2
CC=       # C compiler to use, default will try to pick between gcc and clang

Profiling

Profiling can be enabled in two way.

Buildin profiler

Enable the dmd build profiler with the PROFILE environment.

make PROFILE=1 DC=dmd <target>

The result of the profile can be sorted and displayed with the tprofile (onetool).

Profiling Valgrind

Valgrind profiler can be started with the VALGRIND environment.

Run the unittest with valgrind and callgrind.

make VALGRIND=1 unittest

Any of the test/bdd target can be executed with the VALGRIND=1.

Note. The result from the callgrind viewed with Kcachegrind.

Generating Docs

Installation

You have to install docsify globally.

npm i docsify-cli -g

Building the docs

To build the docs use the command:

make ddoc

Running the document servers

make servedocs

This will start two servers ( default 3000 and 3001 ), with each of them running the different servers.
