Publishing Repositories Using CherryPy
Introduction
For a really really simple way of publishing your Mercurial repositories on the Web without the need for Apache or IIS.
Some quotes from the CherryPy Web site:
CherryPy is a pythonic, object-oriented HTTP framework.
CherryPy powered web applications are in fact stand-alone Python applications embedding their own multi-threaded web server.
CherryPy applications run on Windows, Linux, Mac OS X and any other platform supporting Python.
CherryPy can run WSGI compliant applications like hgweb and hgwebdir.
Pre-requisites
Python 2.4 or newer (http://www.python.org/download/)
CherryPy 3.1 or newer (http://www.cherrypy.org/)
If you want authentication you will need Paste (http://pypi.python.org/pypi/Paste), I used version 1.7.2
Read PublishingRepositories and HgWebDirStepByStep first to get an understanding of hgweb, hgwebdir, the hgweb.config file and Mercurial Lib folder setup.
Running HgWebDir
Here is my sample code that uses the hgwebdir module. Edit this code to suit your needs:
1 # cphgwebdir.py
2
3 # Adjust host and port to suit your Web presence:
4 sUrlHost='0.0.0.0'
5 iUrlPort=8080
6
7 # Adjust encoding to suit or comment out:
8 import os
9 os.environ['HGENCODING']='UTF-8'
10
11 import sys
12 # Adjust path to your Mercurial Lib folder:
13 sys.path.append(r'C:\Program Files\Mercurial\Lib')
14 from mercurial.hgweb.hgwebdir_mod import hgwebdir
15
16 import cherrypy
17 cherrypy.config.update({
18 # Default is development environment, uncomment below when in production
19 #'environment':'production',
20 'server.socket_host':sUrlHost,
21 'server.socket_port':iUrlPort,
22 #'log.access_file':'access.log',
23 'log.error_file':'error.log',
24 'log.screen':True
25 })
26 # Use same hgweb.config file as for hgwebdir.cgi
27 cherrypy.tree.graft(hgwebdir('hgweb.config'),script_name='/')
28 cherrypy.engine.start()
29 cherrypy.engine.block()
sUrlHost can be IP number or domain name (usually, depending on how your network is set up).
Save this code into the same folder as hgweb.config. Unless you have added a path, then save to the root of that path.
Suggested filename is cphgwebdir.py
From a command line just execute the file, like this from its folder:
/path/to/python cphgwebdir.py
That's it.
Running HgWebDir with Digest Authentication
This is a modification of the above code. Edit this code to suit your needs:
1 # cphgwebdir.py with digest authentication
2 import os
3 import sys
4 import cherrypy
5 from paste.auth.digest import AuthDigestHandler, digest_password
6
7 # Adjust host and port to suit your Web presence:
8 sUrlHost='0.0.0.0'
9 iUrlPort=8080
10
11 # Adjust encoding to suit or comment out:
12 os.environ['HGENCODING']='UTF-8'
13
14 # Adjust path to your Mercurial Lib folder:
15 sys.path.append(r'C:\Program Files\Mercurial\Lib')
16 from mercurial.hgweb.hgwebdir_mod import hgwebdir
17
18 # Use same hgweb.config file as for hgwebdir.cgi
19 WsgiApp=hgwebdir('hgweb.config')
20
21 # Adjust realm to suit your needs
22 Realm='Mercurial Repositories'
23
24 # This is a sample dictionary of valid users with their digest encrypted password
25 dAuth={}
26 dAuth['Alice']=digest_password(Realm,'Alice','secret')
27 dAuth['Dilbert']=digest_password(Realm,'Dilbert','secret')
28 dAuth['Wally']=digest_password(Realm,'Wally','secret')
29 #dAuth['<username>']=digest_password('<realm>','<username>','<password>')
30
31 def AuthFunc(environ,realm,username):
32 return dAuth.get(username,None)
33
34 WsgiApp=AuthDigestHandler(WsgiApp,Realm,AuthFunc)
35
36 cherrypy.config.update({
37 # Default is development environment, uncomment below when in production
38 #'environment':'production',
39 'server.socket_host':sUrlHost,
40 'server.socket_port':iUrlPort,
41 #'log.access_file':'access.log',
42 'log.error_file':'error.log',
43 'log.screen':True
44 })
45 cherrypy.tree.graft(WsgiApp,script_name='/')
46 cherrypy.engine.start()
47 cherrypy.engine.block()
Note: do not try tools.wsgiapp as it does not work in this case and has been deprecated, and will be removed in Cherrypy 3.2
Running HgWeb
Use this if you don't want the fancy browser front-end.
Here is my sample code that uses the hgweb module. Edit this code to suit your needs:
1 # cphgweb.py
2
3 # Adjust host and port to suit your Web presence:
4 sUrlHost='0.0.0.0'
5 iUrlPort=8080
6
7 # Change this to represent your repository/ies:
8 lRepos=[
9 #('<virtual path>','<absolute path>'),
10 ('/project1',r'C:\Program Files\DemoRepos\project1'),
11 ('/project2',r'C:\Program Files\DemoRepos\project2'),
12 ('/project3',r'C:\Program Files\DemoRepos\project3')
13 ]
14
15 # Adjust encoding to suit or comment out:
16 import os
17 os.environ['HGENCODING']='UTF-8'
18
19 import sys
20 # Adjust path to your Mercurial Lib folder:
21 sys.path.append(r'C:\Program Files\Mercurial\Lib')
22 from mercurial.hgweb.hgweb_mod import hgweb
23
24 import cherrypy
25 cherrypy.config.update({
26 # Default is development environment, uncomment below when in production
27 #'environment':'production',
28 'engine.autoreload.on':True,
29 'server.socket_host':sUrlHost,
30 'server.socket_port':iUrlPort,
31 'log.error_file':'error.log',
32 'log.screen':True
33 })
34 for (sName,sPath) in lRepos:
35 cherrypy.tree.graft(hgweb(sPath),script_name=sName)
36 cherrypy.engine.start()
37 cherrypy.engine.block()
sUrlHost can be IP number or domain name (usually, depending on how your network is set up).
Change tuples in lRepos list to indicate the repositories that you want published, first element of each tuple must have a leading forward slash.
Suggested filename is cphgweb.py
From a command line just execute the file, like this from its folder:
/path/to/python cphgweb.py
You can make changes to the lRepos list while it is running, saving changes will initiate a restart.
Example command:
hg clone "http://192.168.0.10:8080/project2"
Running HgWebDir As a Windows Service
Here is some example code on how to run hgwebdir and cherrypy as a windows service. It is basically a combination of the above example and the example from cherry's web site: http://tools.cherrypy.org/wiki/WindowsService.
Notice the assignments to sys.stdout and sys.stderr without them you'll get a 500 internal error back when running as a service. It will however run fine in debug mode. Took me a while to figure that out

36 # redirect stdout to stderr.
37 sys.__stdout__ = open('NUL', 'a+')
38 sys.__stderr__ = open('NUL', 'a+')
39
40 cherrypy.tree.graft(hgwebdir('hgweb.config'), script_name='/')
41
42 cherrypy.config.update({
43 'global':{
44 #'environment':'production',
45 'engine.autoreload_on': False,
46 'server.socket_host':URL_HOST,
47 'server.socket_port':URL_PORT,
48 'log.screen': False,
49 'log.error_file':'D:/Projects/python/cphgweb/error.log',

54
55 cherrypy.engine.start()

58 win32event.WaitForSingleObject(self.stop_event, win32event.INFINITE)

63 win32event.SetEvent(self.stop_event)

Run:

And your service should be running.
