=head1 GIT SMART HTTP SUPPORT
97

  
98
Git's smart HTTP protocol will not work with the above settings. Redmine.pm
99
normally does access control depending on the HTTP method used: read-only
100
methods are OK for everyone in public projects and members with read rights
101
in private projects. The rest require membership with commit rights in the
102
project.
103

  
104
However, this scheme doesn't work for Git's smart HTTP protocol, as it will use
105
POST even for a simple clone. Instead, read-only requests must be detected
106
using the full URL (including the query string): anything that doesn't belong
107
to the git-receive-pack service is read-only.
108

  
109
To activate this mode of operation, add this line inside your <Location /git>
110
block:
111

  
112
  RedmineGitSmartHttp yes
113

  
114
Here's a sample Apache configuration which integrates git-http-backend with
115
a MySQL database and this new option:
116

  
117
   SetEnv GIT_PROJECT_ROOT /var/www/git/
118
   SetEnv GIT_HTTP_EXPORT_ALL
119
   ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
120
   <Location /git>
121
       Order allow,deny
122
       Allow from all
123

  
124
       AuthType Basic
125
       AuthName Git
126
       Require valid-user
127

  
128
       PerlAccessHandler Apache::Authn::Redmine::access_handler
129
       PerlAuthenHandler Apache::Authn::Redmine::authen_handler
130
       # for mysql
131
       RedmineDSN "DBI:mysql:database=redmine;host=127.0.0.1"
132
       RedmineDbUser "redmine"
133
       RedmineDbPass "xxx"
134
       RedmineGitSmartHttp yes
135
    </Location>
136

  
137
Make sure that all the names of the repositories under /var/www/git/ match
138
exactly the identifier for some project: /var/www/git/myproject.git won't work,
139
due to the way this module extracts the identifier from the URL.
140
/var/www/git/myproject will work, though. You can put both bare and non-bare
141
repositories in /var/www/git.
142

  
143
Once you have activated this option, you have two options when cloning a
144
repository. Cloning using "http://user@host/git/repo" works, but will ask for
145
the password all the time. To avoid being pestered by password requests, it's
146
best to create a ~/.netrc file with your username and password, and clone using
147
"http://host/git/repo" instead.
148

  
149
IMPORTANT NOTE: It is *very important* that the file cannot be read by other
150
users, as it will contain your password in cleartext. To create the file, you
151
can use the following commands, replacing yourhost, youruser and yourpassword
152
with the right values:
153

  
154
  touch ~/.netrc
155
  chmod 600 .netrc
156
  echo -e "machine yourhost\nlogin youruser\npassword yourpassword" > ~/.netrc
