* Dust

A daemon for disseminating events over a peer-to-peer network.

** Install

*** Requirements

- [[https://code.call-cc.org/][CHICKEN Scheme 4.x]]

- [[https://libsodium.org][libsodium]]

- [[https://symas.com/offerings/lightning-memory-mapped-database/][LMDB]]

- [[http://miniupnp.free.fr/][miniupnpc]]

#+BEGIN_SRC shell

  sudo apt-get install chicken-bin libsodium-dev liblmdb-dev libminiupnpc-dev

#+END_SRC

Currently (until https://bugs.call-cc.org/ticket/1352 is resolved), a patched version of the unix-sockets egg is required. Please fetch the source for this egg by doing:

#+BEGIN_SRC shell

  chicken-install -r unix-sockets

#+END_SRC

Then apply the patch from the ticket and, in the unix-sockets directory, do:

#+BEGIN_SRC shell

  chicken-install -s

#+END_SRC

*** Build and install

#+BEGIN_SRC shell

  chicken-install -s

#+END_SRC

*** OpenBSD

On OpenBSD 6.1, I install these packages:

#+BEGIN_SRC shell

  doas pkg_add chicken sodium miniupnpc

#+END_SRC

Then install LMDB from source:

#+BEGIN_SRC shell

  git clone git://github.com/LMDB/lmdb

  cd lmdb

  git checkout LMDB_0.9.19

  make

  # "make install" doesn't work for me as the expected binaries don't all build

  doas cp liblmdb.so /usr/local/lib/

  doas cp liblmdb.a /usr/local/lib/

  doas cp lmdb.h /usr/local/include/

#+END_SRC

Then build and install dust:

#+BEGIN_SRC shell

  cd dust

  CPATH=/usr/local/include doas chicken-install

#+END_SRC

Note: LMDB has to be used in MDB_WRITEMAP mode on OpenBSD due to the

lack of a unified buffer cache. LMDB environments will reserve their

full mapsize instead of growing as entries are added and nested

transactions will not be supported.

** Run tests

Install test dependencies.

#+BEGIN_SRC shell

  chicken-install -s test test-generative data-generators

#+END_SRC

Run the unit tests.

#+BEGIN_SRC shell

  csi -s tests/run.scm

#+END_SRC
