Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
Overview
========
Nix is a package manager, deployment system, and component glue
mechanism.
Prerequisites
=============
* Berkeley DB 4.0.14
* CWI ATerm 2.0
Installation
============
* When building from the Subversion repository, first do:
autoreconf -i
* To build, do:
./configure
make
make install
Note that this will install to /nix, which is the default prefix.
You can specify another prefix, but this is not recommended if you
want to use prebuilt packages from other sources.
Usage
