Directory Structure

GitBucket persists all data into HOME/.gitbucket in default (In 1.9 or before, HOME/gitbucket is default).

This directory has following structure:

* /HOME/gitbucket
  * /repositories 
    * /USER_NAME
      * / REPO_NAME.git (substance of repository. GitServlet sees this directory)
      * / REPO_NAME
        * /issues (files which are attached to issue)
      * / REPO_NAME.wiki.git (wiki repository)
  * /data
    * /USER_NAME
      * /files
        * avatar.xxx (image file of user avatar)
  * /plugins
    * /PLUGIN_NAME
      * plugin.js
  * /tmp
    * /_upload
      * /SESSION_ID (removed at session timeout)
        * current time millis + random 10 alphanumeric chars (temporary file for file uploading)
    * /USER_NAME
      * /init-REPO_NAME (used in repository creation and removed after it) ... unused since 1.8
      * /REPO_NAME.wiki (working directory for wiki repository) ... unused since 1.8
      * /REPO_NAME
         * /download (temporary directories are created under this directory)

There are some ways to specify the data directory instead of the default location.

1. Environment variable GITBUCKET_HOME
2. System property gitbucket.home (e.g. -Dgitbucket.home=PATH_TO_DATADIR)
3. Command line option for embedded Jetty (e.g. java -jar gitbucket.war --data=PATH_TO_DATADIR)
4. Context parameter gitbucket.home in web.xml like below:

   <context-param>
   <param-name>gitbucket.home</param-name>
   <param-value>PATH_TO_DATADIR</param-value>
   </context-param>
