Sharing source with Mercurial is not hard. There is quite a good guide at Martin's Blog and, indeed, first part of this post will mostly follow his setup.
Sharing sources with password authentication is still not hard but (at least from my perspective) is not obvious. This post will document my efforts of creating private and password protected Mercurial storage.
This procedure is tested on Ubuntu 10.04.1 LTS but I would expect it to work on older versions as well.
First we need to install it's package.

/srv/hg/ = /srv/hg/In newer Mercurial installations you also need to edit "/srv/hg/cgi-bin/hgweb.cgi" in order to fix config parameter. Just change example config line with:

ldconfig deferred processing now taking placeWe need new configuration for web interface of our repositories ("/etc/apache2/sites-available/hg") with following content:
NameVirtualHost *
<VirtualHost *>
ServerAdmin webmaster@localhost
DocumentRoot /srv/hg/cgi-bin/
<Directory "/srv/hg/cgi-bin/">
SetHandler cgi-script
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog /var/log/apache2/hg.log
<Location />
AuthType Basic
AuthName "Mercurial"
AuthUserFile /srv/hg/.htpasswd
Require valid-user
</Location>
</VirtualHost>Lines under Location are ones that ensure privacy of our repository.
We can now disable default web site and enable new one (and we can ignore all warnings) together with changes of ownership and rights:
$ sudo chown -R www-data /srv/hg
$ sudo chmod a+x /srv/hg/cgi-bin/hgweb.cgi
$ sudo a2dissite default
Site default disabled.
Run '/etc/init.d/apache2 reload' to activate new configuration!
$ sudo a2ensite hg

[warn] NameVirtualHost *:80 has no VirtualHostsIf we try to access "http://localhost" now, we should be greeting with password prompt.
Thing that we are missing is "/srv/hg/.htpasswd" file. We can create all users we need with htpasswd command:
$ sudo htpasswd -c /srv/hg/.htpasswd testuser
New password:
Re-type new password:
Adding password for user testuserAll further users are then added with slightly modified command (notice that -c is missing):
$ sudo htpasswd /srv/hg/.htpasswd testuser2
New password:
Re-type new password:
Adding password for user testuser2After creating repository itself
$ sudo hg init /srv/hg/TestRepowe must also create "/srv/hg/TestRepo/.hg/hgrc" file with following content:
[web]
push_ssl=false
allow_push=testuserThis allows for using http (instead of https) and allows access to our "testuser" (if there are no restricturons, just put * for user name). Very last step in setup is actually allowing apache to use our repository for writing. Easiest thing to do here is just transferring ownership to it:
$ sudo chown -R www-data /srv/hg/TestRepoFinally we can use "http://192.168.0.2/hgweb.cgi/TestRepo/" for pushing and pulling data from any Mercurial client.
P.S. To use https, check second post of a series.
