Perlbal::Test - Test harness for perlbal server


# my $msock = Perlbal::Test::start_server();


Perlbal::Test provides access to a perlbal server running on the local host, for testing purposes.

The server can be an already-existing server, a child process, or the current process.

Various functions are provided to interact with the server.


mgmt_port() ^

Return the current management port number.

dump_res($http_response) ^

Return a readable string formatted from an HTTP::Response object. Only the first 80 characters of returned content are returned.

tempdir() ^

Return a newly created temporary directory. The directory will be removed automatically upon program exit.

new_port() ^

Return the next free port number in the series. Port numbers are assigned starting at 60000.

test_port() ^

Return 1 if the port is free to use for listening on $free_port else return 0.

filecontent($file> ^

Return a string containing the contents of the file $file. If $file cannot be opened, then return undef.

foreach_aio($callback) ^

Set the server into each AIO mode (none, ioaio) and call the specified callback function with the mode name as argument.

manage($cmd, %opts) ^

Send a command $cmd to the server, and return the response line from the server.

Optional arguments are:

  quiet_failure => 1

Output a warning if the response indicated an error, unless $opts{quiet_failure} is true, or the command was 'shutdown' (which doesn't return a response).

manage_multi($cmd) ^

Send a command $cmd to the server, and return a multi-line response. Return the number zero if there was an error or no response.

start_server($conf) ^

Optionally start a perlbal server and return a socket connected to its management port.

The argument $conf is a string specifying initial configuration commands.

If the environment variable TEST_PERLBAL_FOREGROUND 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, exit() will be called to terminate the process.

If the environment variable TEST_PERLBAL_USE_EXISTING is set to a true value then a socket will be returned which is connected to an existing server's management port.

Otherwise, a child process is forked and a socket is returned which is connected to the child's management port.

The management port is assigned automatically, a new port number each time this function is called. The starting port number is 60000.

msock() ^

Return a reference to the socket connected to the server's management port.

ua() ^

Return a new instance of LWP::UserAgent.

wait_on_child($pid, $port) ^

Return a socket which is connected to a child process.

$pid specifies the child process id, and $port is the port number on which the child is listening.

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.

resp_from_sock($sock) ^

Read an HTTP response from a socket and return it as an HTTP::Response object

In scalar mode, return only the $http_response object.

In array mode, return an array of ($http_response, $firstline) where $firstline is the first line read from the socket, for example:

"HTTP/1.1 200 OK"
