help

Prints help with available options

version

quiet

Decreases the verbosity, can be repeated

log=xxxx

Tune the log level mask. The levels are:

  • error
  • warning
  • notice
  • info
  • debug

The level can be set using + or -.

Examples descritpion
error,warning selects only the levels error and warning

port=xxxx

HTTP listening TCP port [default 1234]

workdir=xxxx

Directory where the daemon must run [default: $PWD if defined or the current working directory]

uploaddir=xxxx

Directory where uploaded files are temporarily stored [default: workdir]

rootdir=xxxx

Root directory of the application to serve [default: workdir]

roothttp=xxxx

Directory of HTTP served files. If not set, files are not served but apis are still accessible.

rootbase=xxxx

Angular Base Root URL [default /opa]

This is used for any application of kind OPA (one page application). When set, any missing document whose url has the form /opa/zzz is translated to /opa/#!zzz

rootapi=xxxx

HTML Root API URL [default /api]

The bindings are available within that url.

alias=xxxx

Maps a path located anywhere in the file system to the a subdirectory. The syntax for mapping a PATH to the subdirectory NAME is: –alias=/NAME:PATH.

Example: –alias=/icons:/usr/share/icons maps the content of /usr/share/icons within the subpath /icons.

This option can be repeated.

apitimeout=xxxx

binding API timeout in seconds [default 20]

Defines how many seconds maximum a method is allowed to run. 0 means no limit.

cntxtimeout=xxxx

Client Session Timeout in seconds [default 32000000 that is 1 year]

cache-eol=xxxx

Client cache end of live [default 100000 that is 27,7 hours]

session-max=xxxx

Maximum count of simultaneous sessions [default 200]

ldpaths=xxxx

Load bindings from given paths separated by colons as for dir1:dir2:binding1.so:… [default = $libdir/afb]

You can mix path to directories and to bindings. The sub-directories of the given directories are searched recursively.

The bindings are the files terminated by ‘.so’ (the extension so denotes shared object) that contain the public entry symbol.

weak-ldpaths=xxxx

Same as –ldpaths but instead of stopping on error, ignore errors and continue.

binding=xxxx

Load the binding of given path.

token=xxxx

Initial Secret token to authenticate.

If not set, no client can authenticate.

If set to the empty string, then any initial token is accepted.

random-token

Generate a random starting token. See option –exec.

ws-client=xxxx

Transparent binding to a binder afb-daemon service through a WebSocket.

The value of xxxx is either a unix naming socket, of the form “unix:path/api”, or an internet socket, of the form “host:port/api”.

ws-server=xxxx

Provides a binder afb-daemon service through WebSocket.

The value of xxxx is either a unix naming socket, of the form “unix:path/api”, or an internet socket, of the form “host:port/api”.

foreground

Get all in foreground mode (default)

daemon

Get all in background mode

no-httpd

Forbids HTTP serve

exec

Must be the last option for afb-daemon. The remaining arguments define a command that afb-daemon will launch. The sequences @p, @t and @@ of the arguments are replaced with the port, the token and @.

tracereq=xxxx

Trace the processing of requests in the log file.

Valid values are ‘no’ (default), ‘common’, ‘extra’ or ‘all’.

traceapi=xxxx

Trace the accesses to functions of class api.

Valid values are ‘no’ (default), ‘common’, ‘api’, ‘event’ or ‘all’.

traceevt=xxxx

Trace the accesses to functions of class event.

Valid values are ‘no’ (default), ‘common’, ‘extra’ or ‘all’.

call=xxx

Call a binding at start (can be be repeated). The values are given in the form API/VERB:json-args.

Example: –call ‘monitor/set:{“verbosity”:{“api”:”debug”}}’

monitoring

Enable HTTP monitoring at /monitoring/

name=xxxx

Set the visible name

auto-api=xxxx

Automatic activation of api of the given directory when the api is missing.

config=xxxx

Load options from the given config file

This can be used instead of arguments on the command line.

Example:

afb-daemon \
	--no-ldpaths \
	--binding /home/15646/bindings/binding45.so \
	--binding /home/15646/bindings/binding3.so \
	--tracereq common \
	--port 5555 \
	--token SPYER \
	--set api45/key:54027a5e3c6cb2ca5ddb97679ce32f185b067b0a557d16a8333758910bc25a72 \
	--exec /home/15646/bin/test654 @p @t

is equivalent to:

afb-daemon --config /home/15646/config1

when the file /home/15646/config1 is:

{
  "no-ldpaths": true,
  "binding": [
    "\/home\/15646\/bindings\/binding45.so",
    "\/home\/15646\/bindings\/binding3.so"
  ],
  "tracereq": "common",
  "port": 5555,
  "token": "SPYER",
  "set" : {
    "api45": {
      "key": "54027a5e3c6cb2ca5ddb97679ce32f185b067b0a557d16a8333758910bc25a72"
    }
  },
  "exec": [
    "\/home\/15646\/bin\/test654",
    "@p",
    "@t"
  ]
}

The options are the keys of the config object.

See option –dump-config

dump-config

Output a JSON representation of the configuration resulting from environment and options.

output=xxxx

Redirect stdout and stderr to output file

set=xxxx

Set values that can be retrieved by bindings.

The set value can have different formats.

The most generic format is {“API1”:{“KEY1”:VALUE,”KEY2”:VALUE2,…},”API2”:…}

This example set 2 keys for the api chook:

afb-daemon -Z --set '{"chook":{"account":"urn:chook:b2ca5ddb97679","delay":500}}'
{
   "set": {
     "chook": {
       "account": "urn:chook:b2ca5ddb97679",
       "delay": 500
     }
   }
 }

An other format is: [API]/[KEY]:VALUE. When API is omitted, it take the value “”. When KEY is ommitted, it take the value of “”.

The settings for the API * are globals and apply to all bindings.

The settings for the KEY * are mixing the value for the API.

The following examples are all setting the same values:

afb-daemon --set '{"chook":{"account":"urn:chook:b2ca5ddb97679","delay":500}}'
afb-daemon --set 'chook/*:{"account":"urn:chook:b2ca5ddb97679","delay":500}'
afb-daemon --set 'chook/:{"account":"urn:chook:b2ca5ddb97679","delay":500}'
afb-daemon --set 'chook/account:"urn:chook:b2ca5ddb97679"' --set chook/delay:500
