Mergeinfo the versioned property svn:mergeinfo, is the history of merges made into a given file or directory.
I don't regularly check the status of my Drupal server so only after several weeks I realized that Status Report says The server can't issue HTTP requests. It was clear that Status update module doesn't work correctly. When I tried to fix this problem, I have to fight several unrelated problems:
Eclipse 3.4 ships with two update managers, Equinox p2 and old update manager. There has been lot of comments about p2 and it's immaturity.
Drupal 6.x with small modification can also be used on servers with Safe Mode ON (safe_mode=1). Standard distribution of Drupal doesn't support Safe Mode out of the box. Joomla has support already build-in. Safe Mode ON can be bypassed with FTP directory functions.
