Web Remote Procedure Calls (RPCs)

BOINC projects export a number of Web RPCs for creating, querying and updating accounts and host records, and miscellaneous other purposes. These can be used for account management systems and credit statistics web sites.

BOINC's RPC mechanisms have the following conventions:

  • Each RPC is an HTTP GET transaction.
  • The input is the GET arguments, i.e. a string of the form
param1=val1&param2=val2&...&paramn=valn

where param1 ... paramN are the parameter names, and val1 ... valn are the values. Parameter values must be URL-encoded (for example, using PHP's urlencode function).

  • If an RPC fails, the returned XML document is
<error>
    <error_num>N</error_num>
    <error_string>xxx</error_string>
</error>

where N is a BOINC error number and xxx is a textual description. BOINC error numbers are in lib/error_numbers.h; common errors are:

-1
Generic error (error_string may have more info)
-112
Invalid XML (e.g., the preferences passed to am_set_info.php are invalid)
-136
Item not found in database (bad ID of any sort, or ID refers to an item not owned by the caller)
-137
Name is not unique (Can't create account because email address already in use, or can't create team because name is in use)
-138
Can't access database (treat same as -183)
-161
Item not found (deprecated; treat same as -136)
-183
Project is temporarily down
-205
Email address has invalid syntax
-206
Wrong password
-207
Non-unique email address (treat same as -137)
-208
Account creation disabled
  • The output is XML.
  • If the project's get_project_config.php file includes a <rpc_prefix> element, its content should be used as the URL prefix; otherwise use the project's master URL.

Project configuration

Each BOINC project and account manager exports a few configuration items via a web RPC; namely, it must provide an XML document at the address

http://PROJECT_URL/get_project_config.php

This file is created by make_project, and in most cases you don't have to change it.

This document has this structure:

<project_config>
    <name>Project name</name>
    <master_url>URL</master_url>
    [ <local_revision>12345</local_revision> ]
    [ <web_stopped>0|1</web_stopped> ]
    [ <account_creation_disabled/> ]
    [ <client_account_creation_disabled/> ]
    [ <min_passwd_length>N</min_passwd_length> ]
    [ <account_manager/> ]
    [ <uses_username/> ]
    [ <rpc_prefix>URL</rpc_prefix> ]
    [ <error_num>N</error_num> ]
    [
      <platforms>
        <platform>
          <platform_name>i686-apple-darwin</platform_name>
          <user_friendly_name>Mac OS X (Intel)</user_friendly_name>
        </platform>
        <platform>
          <platform_name>i686-pc-linux-gnu</platform_name>
          <user_friendly_name>Linux/x86</user_friendly_name>
        </platform>
        ...
      </platforms>
    ]
    [
      <system_requirements>
        [ <p_fpops>N</p_fpops> ]
        [ <p_iops>N</p_iops> ]
        [ <p_membw>N</p_membw> ]
        [ <m_nbytes>N</m_nbytes> ]
        [ <m_swap>N</m_swap> ]
        [ <d_free>N</d_free> ]
        [ <bwup>N</bwup> ]
        [ <bwdown>N</bwdown> ]
      </system_requirements>
    ]
</project_config>

The elements are:

name
Project name
master_url
Master URL
local_revision
The SVN changeset number of the project's server software.
web_stopped
Nonzero if the project's database is down, so data-driven web pages turned off.
account_creation_disabled
If present, this project is not allowing creation of new accounts
min_passwd_length
Minimum password length (for new account creation)
account_manager
If present, this is an account manager, not a BOINC project
uses_username
If present, this project uses names (rather than email addresses) as the primary account identifier
client_account_creation_disabled
If present, new accounts can be created only via the web (not via the client software).
rpc_prefix
Prefix to use for web RPCs, instead of the master URL.
error_num
The project is currently down. A BOINC error number is returned.
platforms
A list of platforms for which the project has application versions.
system_requirements
Hardware requirements for participating in this project. If a computer doesn't meet these requirements it may not get sent any work by the project. All requirements are 'net'; e.g. the CPU requirements are after factors like on-fraction, active-fraction, and resource share have been taken into consideration. NOT IMPLEMENTED YET.

Server status

BOINC-based projects offer the following XML export at URL/server_status.php. These are generally updated every 10 minutes or so - do not poll more often than that. These can be used to make web sites showing the server status of multiple BOINC projects.
