=head1 DESCRIPTION |
71 |
|
|
|
72 |
root |
1.8 |
With aemp you can configure various aspects of AnyEvent::MP and its |
73 |
root |
1.22 |
protocol, send various messages and even run a node. |
74 |
root |
1.1 |
|
75 |
root |
1.23 |
The F<aemp> utility works like F<cvs>, F<svn> or other commands: the first |
76 |
|
|
argument defines which operation (subcommand) is requested, after which |
77 |
|
|
arguments for this operation are expected. When a subcommand does not eat |
78 |
|
|
all remaining arguments, the remaining arguments will again be interpreted |
79 |
|
|
as subcommand and so on. |
80 |
|
|
|
81 |
|
|
This means you can chain multiple commands, which is handy for profile |
82 |
|
|
configuration, e.g.: |
83 |
|
|
|
84 |
root |
1.27 |
aemp gensecret profile xyzzy binds 4040,4041 nodeid anon/ |
85 |
|
|
|
86 |
|
|
Please note that all C<setxxx> subcommands have an alias without the |
87 |
|
|
C<set> prefix. |
88 |
root |
1.23 |
|
89 |
root |
1.34 |
All configuration data is stored in a human-readable (JSON) config file |
90 |
root |
1.46 |
stored in F<~/.perl-anyevent-mp> (or F<%appdata%/perl-anyevent-mp> on |
91 |
root |
1.49 |
loser systems, or wherever C<$ENV{PERL_ANYEVENT_MP_RC}> points to). Feel |
92 |
root |
1.46 |
free to look at it or edit it, the format is relatively simple. |

=head2 SPECIFYING ARGUMENTS |
95 |
|
|
|
96 |
|
|
Arguments can be specified just as with any other shell command, with a |
97 |
|
|
few special cases: |
98 |
|
|
|
99 |
|
|
If the I<first> argument starts with a literal C<[>-character, then it is |
100 |
|
|
interpreted as a UTF-8 encoded JSON text. The resulting array replaces all |
101 |
|
|
arguments. |
102 |
|
|
|
103 |
|
|
Otherwise, if I<any> argument starts with one of C<[>, C<{> or C<">, then |
104 |
|
|
it is interpreted as UTF-8 encoded JSON text (or a single value in case of |
105 |
|
|
C<">), and the resulting reference or scalar replaces the argument. |
106 |
|
|
|
107 |
|
|
This allows you, for example, to specify binds in F<aemp run> (using POSIX |
108 |
|
|
shell syntax): |
109 |
|
|
|
110 |
|
|
aemp run binds '["*:4040"]' |
111 |

|
|

root |
1.23 |
=head2 RUNNING A NODE |
113 |
|
|
|
114 |
|
|
This can be used to run a node - together with some services, this makes |
115 |
elmex |
1.32 |
it unnecessary to write any wrapper programs. |
116 |
root |

root |
1.30 |
=item run <configure_args>... |
120 |
root |
1.23 |
|
121 |
root |
1.26 |
Runs a node by calling C<AnyEvent::MP::Kernel::configure> with the given |
122 |
root |
1.23 |
arguments. The node runs under L<AnyEvent::Watchdog>, can be restarted |
123 |
root |
1.30 |
(and autorestarted, see the L<AnyEvent::Watchdog> manual). A very common |
124 |
root |
1.33 |
invocation is to just specify a profile using the profile name |
125 |
root |
1.30 |
|
126 |
root |
1.33 |
aemp run database-backend |
127 |
root |
1.30 |
|
128 |
|
|
... but you can use most arguments that C<configure> understands: |
129 |
|
|
|
130 |
|
|
aemp run nodeid mynode2 profile someprofile |
131 |
root |
1.23 |
|
132 |
|
|
Care has been taken to load (almost) no modules other than |
133 |
|
|
L<AnyEvent::Watchdog> and the modules it loads, so everything (including |
134 |
|
|
the L<AnyEvent::MP> modules themselves) will be freshly loaded on restart, |
135 |
|
|
which makes upgrading everything except the perl binary easy. |
136 |
|
|
|
137 |
root |
1.37 |
=item restart <node> |
138 |
|
|
|
139 |
|
|
Restarts the node using C<AnyEvent::Watchdog::Util::restart>. This works |
140 |
|
|
for nodes started by C<aemp run>, but also for any other node that uses |
141 |
|
|
L<AnyEvent::Watchdog>. |

=head2 PROTOCOL COMMANDS |
146 |
|
|
|
147 |
|
|
These commands actually communicate with other nodes. They all use a node |
148 |
elmex |
1.32 |
profile name of C<aemp> (specifying a default node ID of C<anon/> and a |
149 |
root |
1.25 |
binds list containing C<*:*> only). |
150 |
root |
1.23 |
|
151 |
|
|
They all use a timeout of five seconds, after which they give up. |
152 |
|

|
|
|
155 |
|
|
=item snd <port> <arguments...> |
156 |
|
|
|
157 |
|
|
Simply send a message to the given port - where you get the port ID from |
158 |
|
|
is your problem. |
159 |
|
|
|
160 |
|
|
Exits after ensuring that the message has been delivered to its node. |
161 |
|
|
|
162 |
elmex |
1.32 |
Most useful to take advantage of some undocumented functionality inside |
163 |
root |
1.23 |
nodes, such as node ports being able to call any method: |
164 |
|
|
|
165 |
|
|
aemp snd doomed AnyEvent::Watchdog::restart 1 |
166 |
|
|
|
167 |
root |
1.41 |
=item cal <port> <arg...> |
168 |
root |
1.23 |
|
169 |
root |
1.41 |
Like F<aemp cal>: appends a local reply port to the message and waits for |
170 |
|
|
a message to it. |
171 |
root |
1.23 |
|
172 |
|
|
Any return values will be JSON-encoded and printed separated by commas |
173 |
|
|
(kind of like a JSON array without []-brackets). |
174 |
|
|
|
175 |
root |
1.41 |
Example: ask the (undocumented) time service of a node for its current |
176 |
root |
1.23 |
time. |
177 |
|
|
|
178 |
root |

aemp cal mynode time |

1.23 |
|
180 |
|
|
=item mon <port> |
181 |
|
|
|
182 |
|
|
Monitors the port and exits when it's monitorign callback is called. Most |
183 |
|
|
useful to monitor node ports. |
184 |
|
|
|
185 |
|
|
Example: monitor some node. |

|
|
|
189 |
|
|
=item eval <node> <expr...> |
190 |
|
|
|
191 |
|
|
Joins all remaining arguments into a string and evaluates it on the given |
192 |
root |
1.41 |
node. Return values are handled as with F<aemp cal>. |
193 |
root |
1.23 |
|
194 |
|
|
Example: find the unix process ID of the node called posicks. |
195 |
|
|
|
196 |
|
|
aemp eval posicks '$$' |
197 |
|
|
|
198 |
|
|
=item trace <node> |
199 |
|
|
|
200 |
|
|
Asks the given node for all currently connected nodes, then asks those |
201 |
|
|
nodes for the same, thus tracing all node connections. |

=head2 CONFIGURATION/NODE ID/SECRET/CERTIFICATE |
206 |
|
|
|
207 |
|
|
These commands deal with rather basic settings, the node ID, the shared |
208 |
|
|
secret and the TLS certificate. |

|

|
|
=item setnodeid <nodeid> |
213 |
|
|
|
214 |
root |
1.50 |
Set the node ID to the given string. If it ends with a slash (C</>), then |
215 |
|
|
a random string is appended to make it unique. |
216 |
|
|
|
217 |
|
|
If no nodeid is specified in any profile, then the profile name, plus |
218 |
|
|
appended slash, is used. |
219 |
root |
1.23 |
|
220 |
|
|
=item delnodeid |
221 |
|
|
|
222 |
|
|
Removes the node ID again, which means it is inherited again from it's |
223 |
|
|
parent profile, or stays unset. |
224 |
|
|
|
225 |
|
|
=item gensecret |
226 |
|
|
|
227 |
|
|
Generates a random shared secret and sets it. The shared secret is used to |
228 |
|
|
authenticate nodes to each other when TLS is not required. |
229 |
|
|
|
230 |
|
|
=item setsecret <secret> |
231 |
|
|
|
232 |
|
|
Sets the shared secret tot he given string, which can be anything. |
233 |
|
|
|
234 |
|
|
=item delsecret |
235 |
|
|
|
236 |
|
|
Removes the shared secret again, which means it is inherited again from |
237 |
|
|
it's parent profile, or stays unset. |

|
|
|
239 |
|
|
=item gencert |
240 |
|
|
|
241 |
elmex |
1.32 |
Generates a self-signed certificate and key, and sets it. This works |
242 |
root |
1.23 |
similarly to a shared secret: when all nodes have it, TLS will be used to |
243 |
|
|
authenticate and encrypt all traffic. |
244 |
|
|
|
245 |
|
|
=item setcert <file> |
246 |
|
|
|
247 |
|
|
Set a node certificate (and optionally any CA certificates) from the given |
248 |
|
|
file. The file must contain the key, followed by the certificate, followed |
249 |
|
|
by any CA certificates you want to trust, all in PEM format. |
250 |
|
|
|
251 |
|
|
See L<AnyEvent::TLS> for some more details - this sets the C<cert> and |
252 |
|
|
C<ca_cert> options. |
253 |
|
|
|
254 |
|
|
=item delcert |
255 |
|
|
|
256 |
|

Removes the certificate(s) again, which means it is inherited again from |

|
it's parent profile, or stays unset. |

=head2 CONFIGURATION/SEEDS |
262 |
|
|
|
263 |
|
|
To discover the network you have to specify some seed addresses, which are |
264 |
|
|
basically C<host:port> pairs where you expect some long-running nodes. It |
265 |
|
|
does no harm to have a node as its own seed (they will eventually be |
266 |
|
|
ignored). |

|
272 |
|
|
Sets or replaces the list of seeds, which must be specified as a |
273 |
|
|
comma-separated list of C<host:port> pairs. The C<host> can be a hostname, |
274 |
root |
1.36 |
an IP address, or C<*> to signify all local host addresses (which makes |
275 |
|
|
little sense for seeds, outside some examples, but a lot of sense for |
276 |
|
|
binds). |

|
|
301 |
|
|
To be able to be reached from other nodes, a node must I<bind> itself |
302 |
|
|
to some listening socket(s). The list of these can either bs specified |
303 |
|
|
manually, or AnyEvent::MP can guess them. Nodes without any binds are |
304 |
|
|
possible to some extent. |

command for the exact syntax. In addition, a value of C<*> for the port, |
312 |
|
|
or not specifying a port, means to use a dynamically-assigned port. |
313 |

=head2 CONFIGURATION/SERVICES |
345 |
|
|
|
346 |
|
|
Services are modules (or functions) that are automatically loaded (or |
347 |
|
|
executed) when a node starts. They are especially useful when used in |
348 |
|
|
conjunction with F<aemp run>, to configure which services a node should |
349 |
|
|
run. |
350 |
|
|
|
351 |
root |
1.47 |
Despite the daunting name, services really I<are> nothing more than a |
352 |
|
|
module name or a function name with arguments. The "service" aspect comes |
353 |
|
|
only from the behaviour of the module or function, which is supposed to |
354 |
|
|
implement, well, some kind of service for the node, network etc. |
355 |
|
|
|
356 |
|
|
Instead of writing a standalone program for each different node type in |
357 |
|
|
your network, you can simply put your code into a module, and then let the |
358 |
|
|
configuration decide which node runs which "services". This also makes it |
359 |
|
|
easy to combine multiple different services within the same node. |

=item setservices <initfunc>... |
364 |
|
|
|
365 |
|
|
Sets or replaces the list of services, which must be specified as a |
366 |
root |
1.37 |
comma-separated list or a JSON array. |
367 |
|
|
|
368 |
|
|
Each string entry in the list is interpreted as either a module name to |
369 |
|
|
load (when it ends with C<::>) or a function to call (all other cases). |
370 |
|
|
|
371 |
|
|
Each entry which is an array itself (you need to use JSON format to |
372 |
|
|
specify those) is interpreted as a function name and the arguments to |
373 |
|
|
pass. |
374 |
root |
1.23 |
|

The algorithm to find the function is the same as used for C<< |

=head2 CONFIGURATION/PROFILE MANAGEMENT |
402 |
|
|
|
403 |
|
|
All the above configuration functions by default affect the I<global |
404 |
|
|
default configuration>, which is basically used to augment every profile |
405 |
|
|
and node configuration. |

=item profile <name> ... |
410 |
|
|
|
411 |
|
|
This subcommand makes the following subcommands act only on a specific |
412 |
|
|
named profile, instead of on the global default. The profile is created if |
413 |
|
|
necessary. |
414 |
|
|
|
415 |
|
|
Example: create a C<server> profile, give it a random node name, some seed |
416 |
|
|
nodes and bind it on an unspecified port on all local interfaces. You |
417 |
|
|
should add some services then and run the node... |

=item delprofile <name> |

|
Deletes the profile of the given name. |

425 |
root |
1.26 |
=item setparent <name> |
426 |
root |
1.24 |
|
427 |
|
|
Sets the parent profile to use - values not specified in a profile will be |
428 |
|
|
taken from the parent profile (even recursively, with the global default |
429 |
|
|
config being the default parent). This is useful to configure profile |
430 |
|
|
I<classes> and then to inherit from them for individual nodes. |
431 |
|
|
|
432 |
|
|
Note that you can specify circular parent chains and even a parent for the |
433 |
|
|
global configuration. Neither will do you any good, however. |
434 |
|
|
|
435 |
|
|
Example: inherit all values not specified in the C<doomed> profile from |
436 |
|
|
the C<server> profile. |
437 |
|
|
|
438 |

1.24 |

440 |
|
|
=item delparent |
441 |
|
|
|
442 |
|
|
Removes the parent again from the profile, if any was set, so the profile |
443 |
|
|
inherits directly from the global default config again. |
444 |
|
|
|
445 |
root |
1.23 |
=item showprofile <name> |
446 |
|
|

447 |

|
Shows the values of the given profile, and only those, no inherited |
448 |
|
|
values. |
449 |
|
|
|
450 |
root |
1.25 |
=item showconfig <name> <key value...> |
451 |
root |
1.23 |
|
452 |
root |
1.24 |
Shows the I<effective> config, i.e. the values as used by a node started |
453 |
root |
1.25 |
with the given profile name. Any additional key-value pairs specified |
454 |
root |
1.26 |
augment the configuration, just as with C<configure>. |

=head2 LOW-LEVEL TRANSPORT PROTOCOL |
461 |
|
|
|
462 |
|
|
The low-level transport protocol betwene two nodes also has a number of |
463 |
|
|
configurable options, most of which should not be touched unless you know |
464 |
|
|
what you are doing. |

=item [set|del]monitor_timeout <seconds> |
469 |
|
|
|
470 |
|
|
Sets the default monitor timeout, that is, when a connection to a node |
471 |
|
|
cannot be established within this many seconds, the node is declared |
472 |
|
|
unreachable and all monitors will fire. |
473 |
|
|
|
474 |
|
|
C<30> seconds are usually a good time span for this. |
475 |
|
|
|
476 |
|
|
=item [set|del]connect_interval <seconds> |
477 |
|
|
|
478 |
|
|
When a connection cannot be established successfully within this many |
479 |
|
|
seconds, try the next transport address (e.g. the next IP address). If |
480 |
|
|
your nodes have a lot of transports, you might have to set this to a low |
481 |
|
|
value so that they will actually all be tried within the monitor timeout |
482 |
|
|
interval. |
483 |
|
|
|
484 |
|
|
C<2> is usually a good value, unless you live in new zealand. |

|

|
=item [set|del]framing_format [array] |
487 |
|
|
|
488 |
|
|
Configures the list of framing formats offered to the other side. This is |
489 |
|
|
simply a list of formatted read/write types used with L<AnyEvent::Handle>, |
490 |
|
|
in order of decreasing preference. |
491 |
|
|
|
492 |
|
|
Nodes support both C<json> and C<storable> framing formats for data |
493 |
|
|
packets out of the box, and usually choose C<json> because it is first in |
494 |
|
|
the list. |
495 |
|
|
|
496 |
|
|
Example: prefer the C<My::Personal::Format> framing format over JSON over |
497 |
|
|
Storable. |
498 |
|
|
|
499 |
|
|
aemp setframing_format '["My::Personal::Format", "json", "storable"]' |

|
|
501 |
|
|
=item [set|del]auth_offer [array] |
502 |
|
|
|
503 |
|
|
Configures the list of authentication types that the node offers to the |
504 |
|
|
other side as acceptable, in order of decreasing preference. Only auth |
505 |
|
|
methods that the node can actually support will be offered. |
506 |
|
|
|
507 |
|
|
The default is '["tls_md6_64_256", "hmac_md6_64_256"]' and is usually good |
508 |
|
|
enough. |
509 |
|
|
|
510 |
|
|
=item [set|del]auth_accept [array] |
511 |
|
|
|
512 |
|
|
Configures the list of authentication types that remote nodes can use to |
513 |
|
|
authenticate, in order of decreasing preference. |
514 |
|
|
|
515 |
|
|
The default is '["tls_md6_64_256", "hmac_md6_64_256", "tls_anon", |
516 |
|
|
"cleartext"]' and is usually good enough. |

|
|
518 |
|
|
=item [set|del]autocork <boolean> |
519 |
|
|
|
520 |
|
|
Sets the default C<autocork> option value for the L<AnyEvent::Handle> |
521 |
|
|
object used by transports. By default, autocorking is off. |
522 |
|
|
|
523 |
|
|
=item [set|del]nodelay <boolean> |
524 |
|
|
|
525 |

Sets the default C<nodelay> option value for the L<AnyEvent::Handle> |
