#fetch_changesetsObject

With SCMs that have a sequential commit numbering, such as Subversion and Mercurial, Redmine is able to be clever and only fetch changesets going forward from the most recent one it knows about.

However, Git does not have a sequential commit numbering.

In order to fetch only new adding revisions, Redmine needs to save “heads”.

In Git and Mercurial, revisions are not in date order. Redmine Mercurial fixed issues.

* Redmine Takes Too Long On Large Mercurial Repository
  http://www.redmine.org/issues/3449
* Sorting for changesets might go wrong on Mercurial repos
  http://www.redmine.org/issues/3567

Database revision column is text, so Redmine can not sort by revision. Mercurial has revision number, and revision number guarantees revision order. Redmine Mercurial model stored revisions ordered by database id to database. So, Redmine Mercurial model can use correct ordering revisions.

Redmine Mercurial adapter uses “hg log -r 0:tip –limit 10” to get limited revisions from old to new. But, Git 1.7.3.4 does not support –reverse with -n or –skip.

The repository can still be fully reloaded by calling #clear_changesets before fetching changesets (eg. for offline resync)
