#g2rcdiff rc file differences between g2 and g3

The new rc file has far fewer variables; many have been dropped. You should not see much ill effect though, but please read below.

#rc-preset pre-setting the rc file

Some of these settings are such that you cannot directly run gitolite setup when you're ready to migrate. Instead, you need to run

# (assuming you saved your g2 rc file somewhere)
gitolite print-default-rc > $HOME/.gitolite.rc
$EDITOR $HOME/.gitolite.rc
# make appropriate changes, save
gitolite setup

One example of this is GL_NO_SETUP_AUTHKEYS. If you don't jump in and fix the rc first, the first run will clobber your authkeys file.

rc file differences

DROPPED variables (possible high impact): these could be show-stoppers for migration, at least for now.

• BIG_INFO_CAP -- if you think you must have this, try it without and see if there's a difference. If you know you need this, convince me.

• GL_ALL_READ_ALL -- same

• GL_NO_CREATE_REPOS -- if you think you need this, email me. I know one group who does need this so I will be putting it in eventually but not right away.

• HTPASSWD_FILE, RSYNC_BASE, SVNSERVE -- need work. Email me if you are using any of these.

• GL_GET_MEMBERSHIPS_PGM -- is high on my todo list

• GL_LOGT -- is now fixed; you can't change it. Email me if this is a problem.

DROPPED variables (medium impact): these have alternative implementations or mechanisms, but you have to do some setup work.

• GL_ADMINDIR -- this is now at a fixed location: ~/.gitolite. If you want it somewhere else go ahead and move it, then place a symlink from the assumed location to the real one.

• REPO_BASE -- this is now at a fixed location: ~/repositories. If you want it somewhere else go ahead and move it, then place a symlink from the assumed location to the real one.

• PROJECTS_LIST -- it's called GITWEB_PROJECTS_LIST now, but more importantly, it is only used by update-gitweb-access-list in src/commands/post-compile. This variable now has nothing to do with gitolite core, and the rc is just helping to store settings for external programs like that one.

  WEB_INTERFACE and GITWEB_URI_ESCAPE are also gone; patches to the update program to directly do those things are welcome. Personally, I think people who use spaces and other funky characters in dir/file names should be shot but luckily no one listens to me :-)

• GL_NO_DAEMON_NO_GITWEB -- uncomment the appropriate lines in the rc file, in both the POST_COMPILE and POST_CREATE trigger sections.

• NICE_VALUE -- uncomment the 'renice 10' line in the rc file. You can also change the 10 to something else if you wish.

• GIT_PATH -- gone, not needed. Just add these lines to the end of the rc file:

  $ENV{PATH}="...whatever you want...";
  1;
  

• GL_NO_SETUP_AUTHKEYS -- comment out the lines that call ssh-authkeys, in the rc file.

• GL_WILDREPOS_DEFPERMS -- if you need this, add a POST_CREATE script that does it. Or email me and I will write it for you.

• UPDATE_CHAINS_TO -- use a [vref][] instead. You can directly use the chained-to script as a VREF; it'll work.

• ADMIN_POST_UPDATE_CHAINS_TO -- add your script to the POST_COMPILE trigger chain. You won't be getting any arguments but for the admin repo the only argument that ever comes in is "refs/heads/master" anyway.

• GL_ADC_PATH -- obsolete; use [commands][] or add [your own][dev-notes].

• GL_ALL_INCLUDES_SPECIAL -- obsolete; @all always includes gitweb and daemon now. Use [deny-rules][] if you want to say R = @all but not have it be visible to gitweb or daemon.

• GL_PERFLOGT -- see the entry for "gl-time" in the [alternative implementations][g2alt] page.

DROPPED variables (no impact/low impact): these variables should not actually affect anything anyway, so even if you had them set you should not feel their loss.

• GL_CONF, GL_KEYDIR, and GL_CONF_COMPILED -- you had no business touching these anyway; if you did, move them into the expected default locations before attempting to run gitolite setup
• GL_PACKAGE_HOOKS -- not needed anymore, but check if you had any custom hooks set there and copy them across.
• GL_WILDREPOS -- dropped; this feature is default now.
• GL_BIG_CONFIG -- dropped; this feature is default now.

RENAMED variables (no impact): these are functionally the same but are renamed.

• REPO_UMASK is now UMASK
• GL_GITCONFIG_KEYS is now GITCONFIG_KEYS
• GL_WILDREPOS_PERM_CATS is now the ROLES hash in the rc file
• GL_SITE_INFO is now SITE_INFO
