=head1 GIT SMART HTTP SUPPORT

Git's smart HTTP protocol (available since Git 1.7.0) will not work with the

above settings. Redmine.pm normally does access control depending on the HTTP

method used: read-only methods are OK for everyone in public projects and

members with read rights in private projects. The rest require membership with

commit rights in the project.

However, this scheme doesn't work for Git's smart HTTP protocol, as it will use

POST even for a simple clone. Instead, read-only requests must be detected using

the full URL (including the query string): anything that doesn't belong to the

git-receive-pack service is read-only.

To activate this mode of operation, add this line inside your <Location /git>

block:

  RedmineGitSmartHttp yes

Here's a sample Apache configuration which integrates git-http-backend with

a MySQL database and this new option:

   SetEnv GIT_PROJECT_ROOT /var/www/git/

   SetEnv GIT_HTTP_EXPORT_ALL

   ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/

   <Location /git>

       Order allow,deny

       Allow from all

       AuthType Basic

       AuthName Git

       Require valid-user

       PerlAccessHandler Apache::Authn::Redmine::access_handler

       PerlAuthenHandler Apache::Authn::Redmine::authen_handler

       # for mysql

       RedmineDSN "DBI:mysql:database=redmine;host=127.0.0.1"

       RedmineDbUser "redmine"

       RedmineDbPass "xxx"

       RedmineGitSmartHttp yes

    </Location>

Make sure that all the names of the repositories under /var/www/git/ have a

matching identifier for some project: /var/www/git/myproject and

/var/www/git/myproject.git will work. You can put both bare and non-bare

repositories in /var/www/git, though bare repositories are strongly

recommended. You should create them with the rights of the user running Redmine,

like this:

  cd /var/www/git

  sudo -u user-running-redmine mkdir myproject

  cd myproject

  sudo -u user-running-redmine git init --bare

Once you have activated this option, you have three options when cloning a

repository:

- Cloning using "http://user@host/git/repo(.git)" works, but will ask for the password

  all the time.

- Cloning with "http://user:pass@host/git/repo(.git)" does not have this problem, but

  this could reveal accidentally your password to the console in some versions

  of Git, and you would have to ensure that .git/config is not readable except

  by the owner for each of your projects.

- Use "http://host/git/repo(.git)", and store your credentials in the ~/.netrc

  file. This is the recommended solution, as you only have one file to protect

  and passwords will not be leaked accidentally to the console.

  IMPORTANT NOTE: It is *very important* that the file cannot be read by other

  users, as it will contain your password in cleartext. To create the file, you

  can use the following commands, replacing yourhost, youruser and yourpassword

  with the right values:

    touch ~/.netrc

    chmod 600 ~/.netrc

    echo -e "machine yourhost\nlogin youruser\npassword yourpassword" > ~/.netrc
