Trac XML-RPC Plugin

Description

This plugin allows Trac plugins to export select parts of their interface via XML-RPC.

It also includes some exported functions for manipulating tickets, with plans to include interfaces to other parts of Trac's API.

The browsable XML-RPC URI suffix is /xmlrpc, however most XML-RPC clients should use the authenticated URL suffix /login/xmlrpc as this is correctly authenticated by Trac.

Note: if you do want to use /xmlprc and unauthenticated access, you must grant the XML_RPC permission to the 'anonymous' user.

WikiRPC API is complete, mostly thanks to mgood.

Ticket API is also complete, with the following types exported: component, version, milestone, type, status, resolution, priority and severity.

For example, for TracHacks the URIs are http://trac-hacks.org/xmlrpc and http://trac-hacks.org/login/xmlrpc (must be authenticated).

Todo

Outstanding tasks are roadmap, timeline, user management (e.g. get a (filtered) user list to assign a task in mylar), plugin management (?)…plus probably more.

Installation

This plugin requires at least Trac 0.10. It will not work with Trac 0.9.x or earlier.

Install in the same manner as any other Trac plugin:

# python setup.py bdist_egg
# cp dist/*.egg /srv/trac/env/plugins

You will also probably need to enable the plugin in your environments trac.ini:

[components]
tracrpc.* = enabled

Problems when AccountManagerPlugin is enabled

If you have the AccountManagerPlugin enabled and you followed their advise/example to disable the standard login module with

[components]
trac.web.auth.LoginModule = disabled

the /login/xmlrpc URL for authorized access will not work as expected. Every access will look like anonymous access.

You can use the HttpAuthPlugin to correct this.

Example

End-User Usage

Obtain and print a list of XML-RPC exported functions available to my user:

import xmlrpclib

server = xmlrpclib.ServerProxy("http://athomas:password@localhost/trac-dev/login/xmlrpc")
for method in server.system.listMethods():
  print method
  print '\n'.join(['  ' + x for x in server.system.methodHelp(method).split('\n')])
  print
  print

The same example using system.multicall(). This reduces network and server load by compacting all of the system.methodHelp() calls into one HTTP POST.

import xmlrpclib

server = xmlrpclib.ServerProxy("http://athomas:password@localhost/trac/devel/login/xmlrpc")

multicall = xmlrpclib.MultiCall(server)
for method in server.system.listMethods():
    multicall.system.methodHelp(method)

for help in multicall():
    lines = help.splitlines()
    print lines[0]
    print '\n'.join(['  ' + x for x in lines[2:]])
    print

List all tickets that are owned by athomas, using the XML-RPC multicall system to issue multiple RPC calls with one HTTP request:

import xmlrpclib

server = xmlrpclib.ServerProxy("http://athomas:password@localhost/trac/devel/login/xmlrpc")

multicall = xmlrpclib.MultiCall(server)
for ticket in server.ticket.query("owner=athomas"):
    multicall.ticket.get(ticket)
print map(str, multicall())

Access the Wiki with WikiRPC

import xmlrpclib

server = xmlrpclib.ServerProxy("http://athomas:password@localhost/trac-dev/login/xmlrpc")

# print the content of WikiStart
print server.wiki.getPage("WikiStart")

# print WikiStart as HTML
print server.wiki.getPageHTML("WikiStart")

# write to the SandBox page from a text file
sandbox_content = file("sandbox.txt").read()
server.wiki.putPage("SandBox", sandbox_content, {"comments": "testing the WikiRPC interface"})

Add an attachment to WikiStart:

import xmlrpclib

server = xmlrpclib.ServerProxy("http://athomas:password@localhost:8080/trunk/login/xmlrpc")

server.wiki.putAttachment('WikiStart/t.py', xmlrpclib.Binary(open('t.py').read()))

API Usage

See the source for details.

Screenshot

If the HTTP request to this URI is not XML, the XmlRpcPlugin will list all exported functions that the current user has permission to use.

XmlRpcPlugin:

• Added system.getAPIVersion(). Returns a two element tuple containing the Trac XML-RPC version number. Closes #652 (refer to this ticket for semantics).
• Added ticket.getTicketFields(). Forwards directly to TicketSystem().get_ticket_fields(). Closes #651.
• Fixed #723.

XmlRpcPlugin:

Applied patch submitted by steffenp@gmx.de, with some modifications. This adds ticket.getRecentChanges() and ticket.getAvailableActions(). Changed wiki.putAttachment() to be completely compatible with WikiRPC, and added wiki.putAttachmentEx() for Trac specific extensions.
