=head1 DESCRIPTION |
63 |
|
|
|
64 |
root |
1.8 |
With aemp you can configure various aspects of AnyEvent::MP and its |
65 |
root |
1.22 |
protocol, send various messages and even run a node. |
66 |
root |
1.1 |
|
67 |
root |
1.23 |
The F<aemp> utility works like F<cvs>, F<svn> or other commands: the first |
68 |
|
|
argument defines which operation (subcommand) is requested, after which |
69 |
|
|
arguments for this operation are expected. When a subcommand does not eat |
70 |
|
|
all remaining arguments, the remaining arguments will again be interpreted |
71 |
|
|
as subcommand and so on. |
72 |
|
|
|
73 |
|
|
This means you can chain multiple commands, which is handy for profile |
74 |
|
|
configuration, e.g.: |
75 |
|
|
|
76 |
root |
1.27 |
aemp gensecret profile xyzzy binds 4040,4041 nodeid anon/ |
77 |
|
|
|
78 |
|
|
Please note that all C<setxxx> subcommands have an alias without the |
79 |
|
|
C<set> prefix. |
80 |
root |
1.23 |
|
81 |
root |
1.34 |
All configuration data is stored in a human-readable (JSON) config file |
82 |
|
|
stored in F<~/.perl-anyevent-mp> (or F<%appdata%/perl-anyevent-mp> |
83 |
|
|
on loser systems). Feel free to look at it or edit it, the format is |
84 |
|
|
relatively simple. |

=head2 SPECIFYING ARGUMENTS |
87 |
|
|
|
88 |
|
|
Arguments can be specified just as with any other shell command, with a |
89 |
|
|
few special cases: |
90 |
|
|
|
91 |
|
|
If the I<first> argument starts with a literal C<[>-character, then it is |
92 |
|
|
interpreted as a UTF-8 encoded JSON text. The resulting array replaces all |
93 |
|
|
arguments. |
94 |
|
|
|
95 |
|
|
Otherwise, if I<any> argument starts with one of C<[>, C<{> or C<">, then |
96 |
|
|
it is interpreted as UTF-8 encoded JSON text (or a single value in case of |
97 |
|
|
C<">), and the resulting reference or scalar replaces the argument. |
98 |
|
|
|
99 |
|
|
This allows you, for example, to specify binds in F<aemp run> (using POSIX |
100 |
|
|
shell syntax): |
101 |
|
|
|
102 |
|
|
aemp run binds '["*:4040"]' |

=head2 RUNNING A NODE |
105 |
|
|
|
106 |
|
|
This can be used to run a node - together with some services, this makes |
107 |
elmex |
1.32 |
it unnecessary to write any wrapper programs. |
108 |

root |
1.30 |
=item run <configure_args>... |
112 |
root |
1.23 |
|
113 |
root |
1.26 |
Runs a node by calling C<AnyEvent::MP::Kernel::configure> with the given |
114 |
root |
1.23 |
arguments. The node runs under L<AnyEvent::Watchdog>, can be restarted |
115 |
root |
1.30 |
(and autorestarted, see the L<AnyEvent::Watchdog> manual). A very common |
116 |
root |
1.33 |
invocation is to just specify a profile using the profile name |
117 |
root |
1.30 |
|
118 |
root |
1.33 |
aemp run database-backend |
119 |
root |
1.30 |
|
120 |
|
|
... but you can use most arguments that C<configure> understands: |
121 |
|
|
|
122 |
|
|
aemp run nodeid mynode2 profile someprofile |
123 |
root |
1.23 |
|
124 |
|
|
Care has been taken to load (almost) no modules other than |
125 |
|
|
L<AnyEvent::Watchdog> and the modules it loads, so everything (including |
126 |
|
|
the L<AnyEvent::MP> modules themselves) will be freshly loaded on restart, |
127 |
|
|
which makes upgrading everything except the perl binary easy. |
128 |
|
|
|
129 |
root |
1.37 |
=item restart <node> |
130 |
|
|
|
131 |
|
|
Restarts the node using C<AnyEvent::Watchdog::Util::restart>. This works |
132 |
|
|
for nodes started by C<aemp run>, but also for any other node that uses |
133 |
|
|
L<AnyEvent::Watchdog>. |

=head2 PROTOCOL COMMANDS |
138 |
|
|
|
139 |
|
|
These commands actually communicate with other nodes. They all use a node |
140 |
elmex |
1.32 |
profile name of C<aemp> (specifying a default node ID of C<anon/> and a |
141 |
root |
1.25 |
binds list containing C<*:*> only). |
142 |
root |
1.23 |
|
143 |
|
|
They all use a timeout of five seconds, after which they give up. |
144 |
|

|
|
|
147 |
|
|
=item snd <port> <arguments...> |
148 |
|
|
|
149 |
|
|
Simply send a message to the given port - where you get the port ID from |
150 |
|
|
is your problem. |
151 |
|
|
|
152 |
|
|
Exits after ensuring that the message has been delivered to its node. |
153 |
|
|
|
154 |
elmex |
1.32 |
Most useful to take advantage of some undocumented functionality inside |
155 |
root |
1.23 |
nodes, such as node ports being able to call any method: |
156 |
|
|
|
157 |
|
|
aemp snd doomed AnyEvent::Watchdog::restart 1 |
158 |
|
|
|
159 |
|
|
=item rpc <port> <arg...> |
160 |
|
|
|
161 |
|
|
Like F<aemp snd>, but appends a local reply port to the message and waits |
162 |
|
|
for a message to it. |
163 |
|
|
|
164 |
|
|
Any return values will be JSON-encoded and printed separated by commas |
165 |
|
|
(kind of like a JSON array without []-brackets). |
166 |
|
|
|
167 |
elmex |
1.32 |
Example: ask the (undocumented) time service of a node for it's current |
168 |
root |
1.23 |
time. |
169 |
|
|
|
170 |

|
|
|
172 |
|
|
=item mon <port> |
173 |
|
|
|
174 |
|
|
Monitors the port and exits when it's monitorign callback is called. Most |
175 |
|
|
useful to monitor node ports. |
176 |
|
|
|
177 |
|
|
Example: monitor some node. |

181 |
|
|
=item eval <node> <expr...> |
182 |
|
|
|
183 |
|
|
Joins all remaining arguments into a string and evaluates it on the given |
184 |
|
|
node. Return values are handled as with F<aemp rpc>. |
185 |
|
|
|
186 |
|
|
Example: find the unix process ID of the node called posicks. |
187 |
|
|
|
188 |
|
|
aemp eval posicks '$$' |
189 |
|
|
|
190 |
|
|
=item trace <node> |
191 |
|
|
|
192 |
|
|
Asks the given node for all currently connected nodes, then asks those |
193 |
|
|
nodes for the same, thus tracing all node connections. |

=head2 CONFIGURATION/NODE ID/SECRET/CERTIFICATE |
198 |
|
|
|
199 |
|
|
These commands deal with rather basic settings, the node ID, the shared |
200 |
|
|
secret and the TLS certificate. |

|
|
=item setnodeid <nodeid> |
205 |
|
|
|
206 |
|
|
Set the node ID to the given string. |
207 |
|
|
|
208 |
|
|
=item delnodeid |
209 |
|
|
|
210 |
|
|
Removes the node ID again, which means it is inherited again from it's |
211 |
|
|
parent profile, or stays unset. |
212 |
|
|
|
213 |
|
|
=item gensecret |
214 |
|
|
|
215 |
|
|
Generates a random shared secret and sets it. The shared secret is used to |
216 |
|
|
authenticate nodes to each other when TLS is not required. |
217 |
|
|
|
218 |
|
|
=item setsecret <secret> |
219 |
|
|
|
220 |
|
|
Sets the shared secret tot he given string, which can be anything. |
221 |
|
|
|
222 |
|
|
=item delsecret |
223 |
|
|
|
224 |
|
|
Removes the shared secret again, which means it is inherited again from |
225 |
|
|
it's parent profile, or stays unset. |
226 |
|
|
|
227 |
|
|
=item gencert |
228 |
|
|
|
229 |
elmex |
1.32 |
Generates a self-signed certificate and key, and sets it. This works |
230 |
root |
1.23 |
similarly to a shared secret: when all nodes have it, TLS will be used to |
231 |
|
|
authenticate and encrypt all traffic. |
232 |
|
|
|
233 |
|
|
=item setcert <file> |
234 |
|
|
|
235 |
|
|
Set a node certificate (and optionally any CA certificates) from the given |
236 |
|
|
file. The file must contain the key, followed by the certificate, followed |
237 |
|
|
by any CA certificates you want to trust, all in PEM format. |
238 |
|
|
|
239 |
|
|
See L<AnyEvent::TLS> for some more details - this sets the C<cert> and |
240 |
|
|
C<ca_cert> options. |
241 |
|
|
|
242 |
|
|
=item delcert |
243 |
|
|
|
244 |
|
|
Removes the certificate(s) again, which means it is inherited again from |
245 |
|
|
it's parent profile, or stays unset. |

=head2 CONFIGURATION/SEEDS |
250 |
|
|
|
251 |
|
|
To discover the network you have to specify some seed addresses, which are |
252 |
|
|
basically C<host:port> pairs where you expect some long-running nodes. It |
253 |
|
|
does no harm to have a node as its own seed (they will eventually be |
254 |
|
|
ignored). |

=item setseeds <host:port>,... |

|
|
260 |
|
|
Sets or replaces the list of seeds, which must be specified as a |
261 |
|
|
comma-separated list of C<host:port> pairs. The C<host> can be a hostname, |
262 |
root |
1.36 |
an IP address, or C<*> to signify all local host addresses (which makes |
263 |
|
|
little sense for seeds, outside some examples, but a lot of sense for |
264 |
|
|
binds). |
265 |

288 |
|
|
|
289 |
|
|
To be able to be reached from other nodes, a node must I<bind> itself |
290 |
|
|
to some listening socket(s). The list of these can either bs specified |
291 |
|
|
manually, or AnyEvent::MP can guess them. Nodes without any binds are |
292 |
|
|
possible to some extent. |

|
|
Sets the list of bind addresses explicitly - see the F<aemp setseeds> |

command for the exact syntax. In addition, a value of C<*> for the port, |
300 |
|
|
or not specifying a port, means to use a dynamically-assigned port. |
301 |

Services are modules (or functions) that are automatically loaded (or |

=item setservices <initfunc>... |
342 |
|
|
|
343 |
|
|
Sets or replaces the list of services, which must be specified as a |
344 |
root |
1.37 |
comma-separated list or a JSON array. |
345 |
|
|
|
346 |
|
|
Each string entry in the list is interpreted as either a module name to |
347 |
|
|
load (when it ends with C<::>) or a function to call (all other cases). |
348 |
|
|
|
349 |
|
|
Each entry which is an array itself (you need to use JSON format to |
350 |
|
|
specify those) is interpreted as a function name and the arguments to |
351 |
|
|
pass. |
352 |
root |
1.23 |
|
353 |
root |
1.37 |
The algorithm to find the function is the same as used for C<< |
354 |
root |

L<AnyEvent::MP>::spawn >>. |

Example: call the mymod::myfun function with arguments 1, 2 and 3. |
361 |
|
|
|
362 |
|
|
aemp setservices '[["mymod::myfun", 1,2,3]]' |

it's parent profile, or stays unset. |

380 |
|
|
|
381 |
|
|
All the above configuration functions by default affect the I<global |
382 |
|
|
default configuration>, which is basically used to augment every profile |
383 |
|
|
and node configuration. |

=item profile <name> ... |
388 |
|
|
|
389 |
|
|
This subcommand makes the following subcommands act only on a specific |
390 |
|
|
named profile, instead of on the global default. The profile is created if |
391 |
|
|
necessary. |
392 |
|
|
|
393 |
|
|
Example: create a C<server> profile, give it a random node name, some seed |
394 |
|
|
nodes and bind it on an unspecified port on all local interfaces. You |
395 |
|
|
should add some services then and run the node... |

=item delprofile <name> |
400 |
|
|
|
401 |
|
|
Deletes the profile of the given name. |
402 |
|
|
|
403 |
root |
1.26 |
=item setparent <name> |
404 |
root |
1.24 |
|
405 |
|
|
Sets the parent profile to use - values not specified in a profile will be |
406 |
|
|
taken from the parent profile (even recursively, with the global default |
407 |
|
|
config being the default parent). This is useful to configure profile |
408 |
|
|
I<classes> and then to inherit from them for individual nodes. |
409 |
|
|
|
410 |
|
|
Note that you can specify circular parent chains and even a parent for the |
411 |
|
|
global configuration. Neither will do you any good, however. |
412 |
|
|
|
413 |
|
|
Example: inherit all values not specified in the C<doomed> profile from |
414 |
|
|
the C<server> profile. |

root |
1.24 |
|
418 |
|
|
=item delparent |
419 |
|
|
|
420 |
|
|
Removes the parent again from the profile, if any was set, so the profile |
421 |
|
|
inherits directly from the global default config again. |
422 |
|
|
|
423 |
root |
1.23 |
=item showprofile <name> |
424 |
|
|
|
425 |
|
|
Shows the values of the given profile, and only those, no inherited |
426 |
|
|
values. |
427 |
|
|
|
428 |
root |
1.25 |
=item showconfig <name> <key value...> |
429 |
root |
1.23 |
|
430 |
root |
1.24 |
Shows the I<effective> config, i.e. the values as used by a node started |
431 |
root |
1.25 |
with the given profile name. Any additional key-value pairs specified |
432 |
root |
1.26 |
augment the configuration, just as with C<configure>. |
433 |
root |
1.24 |
|

If all arguments are omitted, show the global default config. |
