# In Git and Mercurial, revisions are not in date order.
# 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.
# Mercurial adapter uses "hg log -r 0:tip --limit 10"
# to get limited revisions from old to new.
# And Mercurial model stored revisions ordered by database id in database.
# So, Mercurial can use correct order revisions.
#
# But, Git 1.7.3.4 does not support --reverse with -n or --skip.
#
# With SCM's that have a sequential commit numbering, redmine is able to be
# clever and only fetch changesets going forward from the most recent one
# it knows about.
# However, with git, you never know if people have merged
# commits into the middle of the repository history, so we should parse
# the entire log.
#
# Since it's way too slow for large repositories,
# we only parse 1 week before the last known commit.
#
# The repository can still be fully reloaded by calling #clear_changesets
# before fetching changesets (eg. for offline resync)
