.SH "NAME"
Perlbal::Test \- Test harness for perlbal server
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
#  my \f(CW$msock\fR = \fIPerlbal::Test::start_server()\fR;
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Perlbal::Test provides access to a perlbal server running on the
local host, for testing purposes.
.PP
The server can be an already-existing server, a child process, or
the current process.
.PP
Various functions are provided to interact with the server.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.SH "\fImgmt_port()\fP"
.IX Header "mgmt_port()"
Return the current management port number.
.SH "\fIdump_res($http_response)\fP"
.IX Header "dump_res($http_response)"
Return a readable string formatted from an HTTP::Response object.
Only the first 80 characters of returned content are returned.
.SH "\fItempdir()\fP"
.IX Header "tempdir()"
Return a newly created temporary directory. The directory will be
removed automatically upon program exit.
.SH "\fInew_port()\fP"
.IX Header "new_port()"
Return the next free port number in the series. Port numbers are assigned
starting at 60000.
.SH "\fItest_port()\fP"
.IX Header "test_port()"
Return 1 if the port is free to use for listening on \f(CW$free_port\fR else return 0.
.SH "\fIfilecontent($file\fP>"
.IX Header "filecontent($file>"
Return a string containing the contents of the file \f(CW$file\fR. If \f(CW$file\fR
cannot be opened, then return undef.
.SH "\fIforeach_aio($callback)\fP"
.IX Header "foreach_aio($callback)"
Set the server into each \s-1AIO\s0 mode (none, ioaio) and call the specified
callback function with the mode name as argument.
.ie n .SH "\fImanage($cmd, \fP\fI%opts\fP\fI)\fP"
.el .SH "\fImanage($cmd, \fP\f(CI%opts\fP\fI)\fP"
.IX Header "manage($cmd, %opts)"
Send a command \f(CW$cmd\fR to the server, and return the response line from
the server.
.PP
Optional arguments are:
.PP
.Vb 1
\&  quiet_failure => 1
.Ve
.PP
Output a warning if the response indicated an error,
unless \f(CW$opts\fR{quiet_failure} is true, or the command
was 'shutdown' (which doesn't return a response).
.SH "\fImanage_multi($cmd)\fP"
.IX Header "manage_multi($cmd)"
Send a command \f(CW$cmd\fR to the server, and return a multi-line
response. Return the number zero if there was an error or
no response.
.SH "\fIstart_server($conf)\fP"
.IX Header "start_server($conf)"
Optionally start a perlbal server and return a socket connected to its
management port.
.PP
The argument \f(CW$conf\fR is a string specifying initial configuration
commands.
.PP
If the environment variable \s-1TEST_PERLBAL_FOREGROUND\s0 is set to a true
value then a server will be started in the foreground, in which case
this function does not return. When the server function finishes,
\&\fIexit()\fR will be called to terminate the process.
.PP
If the environment variable \s-1TEST_PERLBAL_USE_EXISTING\s0 is set to a true
value then a socket will be returned which is connected to an existing
server's management port.
.PP
Otherwise, a child process is forked and a socket is returned which is
connected to the child's management port.
.PP
The management port is assigned automatically, a new port number each
time this function is called. The starting port number is 60000.
.SH "\fImsock()\fP"
.IX Header "msock()"
Return a reference to the socket connected to the server's management
port.
.SH "\fIua()\fP"
.IX Header "ua()"
Return a new instance of LWP::UserAgent.
.ie n .SH "\fIwait_on_child($pid, \fP\fI$port\fP\fI)\fP"
.el .SH "\fIwait_on_child($pid, \fP\f(CI$port\fP\fI)\fP"
.IX Header "wait_on_child($pid, $port)"
Return a socket which is connected to a child process.
.PP
\&\f(CW$pid\fR specifies the child process id, and \f(CW$port\fR is the port number on
which the child is listening.
.PP
Several attempts are made; if the child dies or a connection cannot
be made within 5 seconds then this function dies with an error message.
.SH "\fIresp_from_sock($sock)\fP"
.IX Header "resp_from_sock($sock)"
Read an \s-1HTTP\s0 response from a socket and return it
as an HTTP::Response object
.PP
In scalar mode, return only the \f(CW$http_response\fR object.
.PP
In array mode, return an array of ($http_response, \f(CW$firstline\fR) where
\&\f(CW$firstline\fR is the first line read from the socket, for example:
.PP
\&\*(L"\s-1HTTP/1\s0.1 200 \s-1OK\s0\*(R"
