\chapter*{Preface}
This document describes a build automation system being developed at
the \elftoolchain project on
\href{http://sourceforge.net/}{SourceForge.Net}. The original
motivation for this system was to automate the process of building and
testing the \elftoolchain project's source tree on a variety of
operating systems and machine architectures. However, the design of
the system is general enough that it can be used in other contexts
too.
The system has been designed to be easy to use and to frugal in its
use of computing resources. For handling non-native platforms, the
system uses emulators such as \href{http://www.qemu.org}{QEMU},
\href{http://gxemul.sourceforge.net/}{GXemul} and
\href{http://www.virtualbox.org}{VirtualBox}. The system is not tied
to these specific emulators---it can as well manage physical machines,
given the appropriate control specifications.
This document itself is a
\href{http://en.wikipedia.org/wiki/Literate_programming}%
{literate program}---it is both a human-readable description of the
system, as well as the source code of the system itself.
\section*{Target Audience}
This document would be useful to two audiences:
\begin{itemize}
\item Users of the system would find part~\ref{part.intro}, which
contains an overview and a user guide, to be of interest.
\item For the maintainers of the system,
part~\ref{part.implementation} contains the implementation itself.
\end{itemize}
\section*{Document Overview}
\begin{itemize}
\item Chapter~\vref{chap.introduction} describes the rationale and the
requirements for the system.
\item Chapter~\vref{chap.userguide} contains a brief user guide
showing how the system may be used.
\item Chapter~\vref{chap.overview} presents an overview of the
implementation.
\item Chapter~\vref{chap.slave} describes the implementation of the
build slave.
\item Chapter~\vref{chap.master} describes the implementation of the
build master.
\end{itemize}

\part{The Build System}\label{part.intro}
\chapter{Introduction}\label{chap.introduction}
\section{Design Goals}
\begin{goal}
The system should support build and testing our source tree, on the
target operating systems and machine architectures of our interest.
\end{goal}
This is the primary design goal for the tool, its
\foreignphrase{raison d'\^etre}.
\begin{goal}
The system should support building and testing our source tree on
non-native architectures (relative to the build host).
\end{goal}
Builds on non-native machine architectures and operating systems are
would involve the use of virtual machines and CPU emulators. The
actual build will be done using \tool{make} or equivalent utility.
\begin{goal}
The system should be easy to use.
\end{goal}
Defining a build needs to be intuitive, and should utilize
pre-existing tools where possible.
The number of new notations and file formats that a user needs to
learn should be kept to a minimum.
Invoking a build should be simple. Sensible defaults should be used
to minimize the need for user input at the time of invocation.
\begin{goal}
The system should be able to run entirely on a relatively power and
resource constrained system such as a laptop, i.e., without needing
a beefy build box, or architecture-specific hardware.
\end{goal}
The ability to be able to work using a low power compute platform is a
necessity in the project's current development environment
The need to be frugal in resource consumption rules out the use of
certain convenient but resource hungry implementation options.
\begin{goal}
The system should work in ``offline'' mode, without requiring
external network access to function.
\end{goal}
The intent is to be able to work in ``standalone'' mode, without
needing to contact a master server on the network.
\begin{goal}
The system should allow a source tree that is in-development to be
built and tested, prior to a check-in.
\end{goal}
This system is primarily a development aid, and not primarily a tool
for implementing continuous integration.
\begin{goal}
The system should be easy to deploy, with the minimum of software
dependencies.
\end{goal}
The fewer dependencies on third party packages, the easier it is to
support target operating systems.
\begin{goal}
The utility should be easy to port to a new operating system.
\end{goal}
This goal is meant to reduce the effort needed to support new
operating systems.

% The build slave.
\chapter{The Build Slave}\label{chap.slave}
\section{Overview}
\paragraph{File structure}
The implementation of the \tool{yabs} slave is structured along
conventional lines.
<<slave/slave.c>>=
<<generated file warning>>
<<slave: include headers>>
<<slave: declare types and constants>>
<<slave: define helper functions>>
<<slave: define main()>>
@
\section{Data Types}
The data structures used in the \tool{yabs} slave are:
\begin{itemize}
\item A data structure to record command-line options
([[struct slave_options]]).
\item Others...(TBD).
\end{itemize}
<<slave: declare types and constants>>=
<<define common constants>>
<<slave: declare slave options>>
@
\paragraph{Slave Options}\label{para:slave-options}
The [[slave_options]] structure is used to track the options
controlling the slave's behavior.
This structure is populated in the \func{main} function.
<<slave: declare slave options>>=
struct slave_options {
char *sl_id;
unsigned long sl_port;
const char *sl_server;
enum yabs_server_type sl_servertype;
int sl_verbose;
};
@ %def slave_options
\begin{itemize}
\item The \var{sl\_id} member specifies the identifier that the slave
sends to the \tool{yabs} despatcher at connect time.
The default identifier is the system's hostname (see chunk
[[<<slave: set the slave identifier if not set>>]]). The ``-i''
option is used to change the identifier (see [[<<slave: handle -i>>]]).
\item The \var{sl\_port} field specifies the TCP port on the server
running the \tool{yabs} despatcher that the slave should connect to.
This is overrideable by the ``-p'' command-line option (see
[[<<slave: handle -p>>]]).
\item The \var{sl\_server} field specifies the server to connect to.
The \var{sc\_servertype} field specifies whether to use a TCP
connection, a local socket, or to use standard input and output
(see [[enum yabs_server_type]]).
\item The \var{sl\_verbose} field specifies the verbosity level for
the slave.
\end{itemize}
<<slave: initialize option structure>>=
options.sl_id = NULL;
options.sl_port = YABS_DEFAULT_DESPATCHER_PORT;
options.sl_server = NULL;
options.sl_servertype = YABS_SERVER_STDIN;
options.sl_verbose = 0;
@
\section{The Program Entry Point}
<<slave: define main()>>=
int
main(int argc, char **argv)
{
<<slave: main: local variables>>
<<slave: initialize option structure>>
<<slave: parse options>>
<<slave: invoke libevent main loop>>
return (0);
}
@ %def main
The [[<<slave: main: local variables>>]] chunk declares the local
variables needed by the function.
\paragraph{Option Parsing}
Option parsing uses the POSIX \func{getopt} API. The end result of
the option parsing is an appropriately configured [[slave_options]]
structure.
<<slave: main: local variables>>=
struct slave_options options;
int option;
@
<<slave: parse options>>=
while ((option = getopt(argc, argv, "hi:p:vV")) != -1) {
switch (option) {
case 'h':
display_usage_message(); exit(0);
break;
case 'i':
<<slave: handle -i>>
break;
case 'p':
<<slave: handle -p>>
break;
case 'v':
<<slave: handle -v>>
break;
case 'V':
<<slave: handle -V>>
break;
case '?':
display_usage_message(); exit(1);
break;
default:
errx(1, "FATAL: Unrecognized option value %c (%d)",
option, option);
break;
}
}
<<slave: set the slave identifier if not set>>
@
\paragraph{Handling ``-i''}
The identifier by which the slave identifies itself to the despatcher
can be set using the ``-i'' option. If this option is specified
multiple times, the last one takes precedence.
<<slave: handle -i>>=
if (options.sl_id)
free(options.sl_id);
options.sl_id = strdup(optarg);
@
\paragraph{Handling ``-p''}
The ``-p'' option is used to specify the port the slave should connect
to. It is required to be a decimal number: we use the \func{strtoul}
function to convert the option argument to a number.
<<slave: main: local variables>>=
char *end;
@
<<slave: handle -p>>=
options.sl_port = strtoul(optarg, &end, 10);
if (options.sl_port == 0 || *end != '\0')
errx(1, "Invalid port number \"%s\"", optarg);
@
\paragraph{Handling ``-v'''}
The ``-v'' option increases verbosity. The current verbosity level is
recorded in the \var{sc\_verbose} field.
<<slave: handle -v>>=
options.sl_verbose++;
@
\paragraph{Handling ``-V''}
The ``-V'' option prints a version number, and exits.
<<slave: declare types and constants>>=
#define YABS_SLAVE_NAME "yabs-slave"
@ %def YABS_SLAVE_NAME
<<slave: handle -V>>=
(void) printf(YABS_SLAVE_NAME " " YABS_SLAVE_VERSION " (Protocol: "
YABS_PROTOCOL_VERSION ")\n");
exit(0);
@
\paragraph{Setting a default identifier}
If an identifier was not specified by a '-i' command line option, we
use the name of the host the slave is running on.
<<slave: set the slave identifier if not set>>=
if (options.sl_id == NULL) {
<<slave: allocate space for the slave identifier>>
<<slave: retrieve the host name>>
}
@
<<slave: allocate space for the slave identifier>>=
if ((options.sl_id = malloc(HOST_NAME_MAX)) == NULL)
err(1, "malloc failed: [%s,%d]", __FILE__, __LINE__);
@
The system's host name is retrieved using the \func{gethostname} library
function. We explicitly NUL-terminate the array after calling \func{gethostname},
since portable programs cannot assume that function does so for host names
that are exactly HOST\_NAME\_MAX bytes long.
<<slave: retrieve the host name>>=
if (gethostname(options.sl_id, HOST_NAME_MAX) < 0)
err(1, "gethostname failed: [%s,%d]", __FILE__, __LINE__);
options.sl_id[HOST_NAME_MAX - 1] = '\0';
@

\section{Header Inclusions}
The use of the \func{errx} family of functions requires the standard
header \file{err.h}.
<<slave: include headers>>=
#include <err.h>
@
The \var{HOST\_NAME\_MAX} constant used in the chunk
[[<<slave: set the slave identifier if not set>>]] is
defined by the \file{limits.h} header.
<<slave: include headers>>=
#include <limits.h>
@
The use of the \func{printf} function requires the use of the system
header \file{stdio.h}.
<<slave: include headers>>=
#include <stdio.h>
@
The header file \file{stdlib.h} is needed for the prototypes for the
\func{exit}, \func{free} and \func{malloc} functions.
<<slave: include headers>>=
#include <stdlib.h>
@
The header file \file{string.h} provides the prototype for
\func{strdup} used in chunk [[<<Handling ``-i''>>]].
<<slave: include headers>>=
#include <string.h>
@
The header file \file{unistd.h} is needed for the prototype for the
\func{getopt} function used in chunk [[<<slave: parse options>>]].
<<slave: include headers>>=
#include <unistd.h>
@
\tool{Libevent} specific headers are needed for the libevent APIs:
<<slave: include headers>>=
#include <event2/event.h>
@
\section{Build Rules}
Using the facilities provided by the standard rules in
\verb|<bsd.prog.mk>|, a simple \file{Makefile} suffices to build the
slave.
The \file{Makefile} indicates that the generated progam is to be
called \tool{yabs-slave} and that the file \file{slave.c} is the
source file to be compiled. The contents of this source file is
defined by the chunk [[<<slave/slave.c>>]].
<<slave/Makefile>>=
PROG= yabs-slave
SRCS= slave.c
CFLAGS+= -Wall -Wextra -Werror -pedantic
<<make: libevent related definitions>>
.include <bsd.prog.mk>
<<make: override debug flags during development>>
@
We look in a set of standard locations to determine where the headers
and library files for \tool{libevent} are located.
<<make: libevent related definitions>>=
.if exists(${HOME}/local/include/event2)
LIBEVENT_INCLUDE= -I ${HOME}/local/include
LIBEVENT_LIB= -L ${HOME}/local/lib
.elif exists(/usr/local/include/event2)
LIBEVENT_INCLUDE= -I /usr/local/include
LIBEVENT_LIB= -L /usr/local/lib
.endif
CFLAGS+= ${LIBEVENT_INCLUDE}
LDADD+= ${LIBEVENT_LIB} -levent
@
Debugging is simpler if compiler optimizations are turned off. We
thus remove the \term{-O2} flag during development.
<<make: override debug flags during development>>=
CFLAGS:= ${CFLAGS:N-O2} -g
LDFLAGS+= -g

% build.
\chapter{Using The Build System}\label{chap.userguide}
This chapter describes how to use the system.
\section{Terminology}
First, some definitions:
\begin{itemize}
\item A \definition{machine} is hardware that could be invoked during
the execution of a job.
A ``machine'' could be a physical machines that is to be powered up
for the job, or a virtual machine that is to be started up.
The \tool{yabs} utility uses user-provided shell script fragments to
control machines. Hence a ``machine'' could also be an invocation
of a remote host via the \tool{ssh} program.
A machine is expected to execute the ``slave'' program (see below)
once it is has booted.
\item A \definition{job definition} specifies the information needed
to run a job. A job definition will specify:
\begin{itemize}
\item The list of machines to be invoked.
\item The specific commands be run inside each machine.
\item The results to retrieved from each machine, after the
commands are run.
\item The name of a ``job scheduler'' (see below).
\end{itemize}
\item A \definition{job} is a particular invocation of a \term{job
definition}.
\item A \definition{job scheduler} is a program that implements the
logic for starting and stopping individual steps that are part of a
job. The system provides a default scheduler which would suffice
for most cases. Users can override the default scheduler if their
jobs have special needs.
\item The \tool{yabs} \definition{slave} is a program that runs
inside a booted machine, running the tasks defined in the
job definition.
\item A \definition{slave script} is a shell script that lists the
actions to be executed inside a particular virtual machine. Slave
scripts are usually written in the shell (\tool{sh}) programming
language.
\end{itemize}
\section{Configuration}
TODO: describe how to configure the tool.
