This — is The Construct

Internet Relay Chat daemon: Matrix Construct

IRCd was a free and open source server which facilitated real-time communication over the internet. It was started by Jarkko Oikarinen in 1988 at the University of Oulu and its derivatives underpinned the major IRC networks for decades.

Due to its age and stagnation since the mid-2000's, a growing number of proprietary cloud services are now filling the vacuum of innovation. In 2014 a new approach was proposed to reinvigorate real-time communication for free and open source software: a federation of networks known as the matrix.

IRCd has been rewritten for the global federation of networks    

This is the Construct — the first Matrix server written in C++. It is designed to be fast and highly scalable, and to be community developed by volunteer contributors over the internet. This mission strives to make the software easy to understand, modify, audit, and extend. It remains true to its roots with its modular design and having minimal requirements.

Even though all of the old code has been rewritten, the same spirit and philosophy of its predecessors is still obvious throughout.

Similar to the legacy IRC protocol's origins, Matrix wisely leverages technologies in vogue for its day to aid the virility of implementations. A vibrant and growing ecosystem already exists.

Installation

Dependencies

• Boost (1.66 or later) Replacing libratbox.
• RocksDB Embedded database.
• Sodium Curve ed25519 for Federation.
• OpenSSL HTTPS TLS / X.509.
• libmagic (~Optional~) MIME type recognition.
• zlib or lz4 or snappy (Optional) Compression.

Build tools

• GNU C++ compiler, automake, autoconf, autoconf2.13, autoconf-archive, libtool.

• A platform capable of loading dynamic shared objects at runtime is required.

DOWNLOAD

At this phase of development the best thing to do is pull the master branch and use the latest head.

The head of the master branch is consistent and should be safe to pull without checking out a release tag. When encountering a problem with the latest head on master that is when a release tag should be sought.

BUILD

Please follow the standalone build instructions in the next section until this notice is removed.

./autogen.sh
./configure
make
sudo make install

Additional documentation for building can be found in doc/BUILD.md

BUILD (standalone)

Intended to allow building with dependencies that have not made their way to mainstream systems.

./autogen.sh
mkdir build

• The install directory may be this or another place of your choosing.
• If you decide elsewhere, make sure to change the --prefix in the ./configure statement below.

./configure --prefix=$PWD/build --with-included-boost --with-included-rocksdb

• The --with-included-* will fetch, configure and build the dependencies included as submodules.

make install

SETUP

• For standalone builds you will need to add the deps/boost/lib directory in your git repo to the library path: export LD_LIBRARY_PATH=/path/to/src/deps/boost/lib:$LD_LIBRARY_PATH

• We will refer to your server as host.tld. For those familiar with matrix: this is your origin and mxid @user:host.tld hostpart. If your DNS uses matrix.host.tld that subdomain is not involved when we refer to host.tld unless we explicitly mention to involve it.

1. Execute

   bin/construct host.tld
   

   There is no configuration file.

   Log messages will appear in terminal concluding with notice IRCd RUN.

2. Strike ctrl-c on keyboard

   The command-line console will appear.

3. Create a general listener socket by entering the following command:

   • If you have existing TLS certificates, replace those parts of the command with paths to your certificate and key, respectively. If you do not, those files will be created and self-signed in the current directory; another target path may be specified.

   net listen matrix 0.0.0.0 8448 host.tld.crt host.tld.crt.key
   

   The Matrix Federation Tester should now pass. Browse to https://matrix.org/federationtester/api/report?server_name=host.tld and verify "AllChecksOK": true

4. Relax restrictions for self-signed certificates.

   • We cannot, in good faith, ship this software configured insecurely by default; therefor we leave this step to you.

   conf set ircd.net.open.allow_self_signed true
   

   Most federation servers are personal deployments with self-signed certificates. Setting this option will decrease federation fragmentation.

5. To use a web-based client like Riot, configure the "webroot" directory to point at Riot's webapp/ directory by entering the following:

   conf set ircd.webroot.path /path/to/riot-web/webapp/
   mod reload webroot
   

6. Browse to https://host.tld:8448/ and register a user.

Plan

Roadmap for service

• Phase One: Matrix clients using HTTPS.
• Phase Two: Legacy IRC network TS6 protocol.
• Phase Three: Legacy IRC clients using RFC1459 / RFC2812 legacy grammars.

Roadmap for deployments

The deployment mode is a macro of configuration variables which tune the daemon for how it is being used. Modes mostly affect aspects of local clients.

• Personal: One or few users. Few default restrictions; higher log output.
• Company: Hundreds of users. Moderate default restrictions.
• Public: Thousands of users. Untrusting configuration defaults.

Roadmap for innovation

• Phase Zero: Core libircd: Utils; Modules; Contexts; JSON; Database; HTTP; etc...
• Phase One: Matrix Protocol: Core VM; Core modules; Protocol endpoints; etc...
• Phase Two: Construct Cluster: Kademlia sharding of events; Maymounkov's erasure codes.
