Pure-PHP Smart HTTP clone, fetch, pull and push for SHA-1 repositories.
Dumb HTTP reads for compatibility and pure-PHP bare-repository creation.
Smart HTTP upload-pack for clone, fetch and pull.
Smart HTTP receive-pack for push.
Remote branch and tag creation, update and deletion through push.
Authenticated bare-repository creation from the home page.
Per-repository controls for reads, pushes, authentication, branch refs, tag refs, other ref namespaces and push request size.

index.php is the application entry point. Protocol responsibilities are split into operations/clone.php, operations/pull.php, operations/push.php, operations/branch.php and operations/tag.php; shared routing, repository, HTTP and Git process code is under lib/.

Requirements

PHP 7.4 or newer.
Apache with mod_rewrite and .htaccess enabled for normal deployment.
PHP zlib and hash extensions for the native Git protocol implementation.
Git and PHP proc_open are optional; when available, Git remains the Smart HTTP backend for full protocol and hook compatibility.
Read access to published repositories; write access is also required for push and for the managed repository directory when home-page creation is enabled.

If Git or proc_open is unavailable, the native PHP backend supports ordinary SHA-1 clone, fetch, pull and push, including deltas, branches and tags. It does not currently support SHA-256 repositories, shallow or filtered fetches, signed push certificates, Git hooks or protocol v2-only features. Push is disabled by default and should be enabled only behind HTTPS and trusted web-server authentication.

Configuration

Copy config.php.sample to config.php, then configure $url_base, $git_executable, $repos and optionally $managed_repositories. A writable repository can be configured as:

$repos = array(
    array('/project.git', '/srv/git/project.git', array(
        'read' => TRUE,
        'push' => TRUE,
        'require_auth' => TRUE,
        'branches' => TRUE,
        'tags' => TRUE,
        'other_refs' => FALSE)));

require_auth trusts only REMOTE_USER, which must be set by authenticated Apache or reverse-proxy configuration. Setting it to FALSE permits anonymous push and is suitable only for isolated development environments.

To create bare repositories from the home page, configure a pre-existing writable directory. Newly created repositories are discovered automatically; the application never rewrites config.php:

$managed_repositories = array(
    'path' => '/srv/git',
    'require_auth' => TRUE,
    'session_cookie_secure' => TRUE,
    'options' => array(
        'read' => TRUE,
        'push' => TRUE,
        'require_auth' => TRUE));

The managed directory must be readable, writable and searchable by PHP and reserved for this application. Set session_cookie_secure to TRUE when HTTPS terminates at a trusted reverse proxy; direct HTTPS deployments are detected from the web-server connection automatically.
