Added branch and tag support to the git repository viewer. (#1406) Many thanks to Adam Soltys and everyone else who tested this patch. * Updated git test repository so it has a branch with some differences from the master branch * Moved redmine diff class into a module so as not to clash with diff-lcs gem which is required by grit * Find changesets from all branches, not just master * Got revision browsing working * Got file actions working properly * Allow browsing by short form of commit identifier * Added a method to retrieve repository branches * Allow browsing by branch names as well as commit numbers * Handle the case where a git repository has no master branch * Expand revision box and handle finding revisions by first 8 characters * Added branches dropdown to repository show page * Combined repository browse and show into a single action. Moved branch/revision navigation into a partial. * Renamed partial navigation -> breadcrumbs * Made it so latest revisions list uses branch and path context * Preserve current path when changing branch or revision * Perform slightly more graceful error handling in the case of invalid repository URLs * Allow branch names to contain periods * Allow dashes in branch names * Sort branches by name * Adding tags dropdown * Need to disable both branches and tags dropdowns before submitting revision form * Support underscores in revision (branch/tag) names * Making file history sensitive to current branch/tag/revision, adding common navigation to changes page * Updated translation files to include labels for 'branch', 'tag', and 'view all revisions' * Reenable fields after submit so they don't look disabled and don't stay disabled on browser back button * Instead of dashes just use empty string for default dropdown value * Individual entry views now sport the upgraded revision navigation * Don't display dropdowns with no entries * Consider all revisions when doing initial load * Fixed bug grabbing changesets. Thanks to Bernhard Furtmueller for catching. * Always check the entire log to find new revisions, rather than trying to go forward from the latest known one * Added some cleverness to avoid selecting the whole changesets table any time someone views the repository root * File copies and renames being detected properly * Return gracefully if no revisions are found in the git log * Applied patch from Babar Le Lapin to improve Windows compatibility git-svn-id: svn+ssh://rubyforge.org/var/svn/redmine/trunk@2840 e93f8b46-1217-0410-a6f0-8f06a7374b81

# 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)

# Git branch is the reference to the specific revision.
# Git can *delete* remote branch and *re-push* branch.

# So, Redmine needs to scan revisions and database every time.
#
# This is replacing the one-after-one queries.
# Find all revisions, that are in the database, and then remove them from the revision array.
# Then later we won't need any conditions for db existence.
# Query for several revisions at once, and remove them from the revisions array, if they are there.
# Do this in chunks, to avoid eventual memory problems (in case of tens of thousands of commits).
# If there are no revisions (because the original code's algorithm filtered them),
# then this part will be stepped over.
