Trying to hack subversion.rb by adding an update_changeset function

Added by Steven Risner over 16 years ago

Our organization often a needs to update svn:properties and I need a way to run a command similar to fetch_changesets via svn post-revprop-change hook.

The function I'd like to define and execute is

def update_changeset(scm_revision)
scm_info = scm.info
if scm_info

latest revision found in database
db_revision = latest_changeset ? latest_changeset.revision.to_i : 0
if db_revision < scm_revision
logger.debug "Changesets for repository #{url} \
out-of-sych use fetch_changesets first" if logger && logger.debug?
else

Get scm revision to update
revision = scm.revisions('', scm_revision, scm_revision, :with_paths => true)
Changeset.update(:repository => self,
:revision => revision.identifier,
:committer => revision.author,
:committed_on => revision.time,
:comments => revision.message)
end
end
end

I'm not a ruby programmer so I sorta winged it by example and assumed the Changeset.update exist (I know update_all does base on other ruby scripts). I'm not sure if this would be all I need, but it seemed resonable.

My first attempt on this was a hard coded scm_revision and update_changeset def with no parameter.

When I tried to execute this using

/usr/bin/ruby runner "Repository.update_changeset" -e production

I got the following ouptut.

/srv/www/redmine/vendor/rails/railties/lib/commands/runner.rb:47: undefined method `update_changeset' for
#<Class:0xb6fa7aec> (NoMethodError)
from (eval):1
from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `eval'
from /srv/www/redmine/vendor/rails/railties/lib/commands/runner.rb:47

from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from runner:3

How can I make the runner.rb aware of this new sunversion.rb method? Once I can get a non-parameter version working how do I pass a parameter using the following.

/usr/bin/ruby runner "Repository.update_changeset" -e production

Hmm sorry some wiki syntax was rendered. ( Wish I could had edited my own post! Why can't I? )

 def update_changeset
    scm_revision = 10102
    scm_info = scm.info
    if scm_info
      # latest revision found in database
      db_revision = latest_changeset ? latest_changeset.revision.to_i : 0
      if db_revision < scm_revision
        logger.debug "Changesets for repository #{url} 
        out-of-sych (use fetch_changesets)" if logger && logger.debug?
      else
          # Get scm revision to update
          revision = scm.revisions('', scm_revision, scm_revision, :with_paths => true)
          Changeset.update(:repository => self,
                           :revision => revision.identifier,
                           :committer => revision.author,
                           :committed_on => revision.time,
                           :comments => revision.message)
      end
    end
  end

The following works

Again I'm not a ruby programmer so it could be done easer

In repository.rb

def self.update_changeset(path,rev)
    find(:all).each do |repos|
        repos.update_changeset(path,rev)
    end
  end

in subversion.rb

def update_changeset(repos, rev)
    scm_info = scm.info
    scm_url  = scm.root_url
    if scm_info
      if scm_url == repos
      # latest revision found in database
      db_revision = latest_changeset ? latest_changeset.revision.to_i : 0
      scm_revision = rev.to_i
      if db_revision < scm_revision
      logger.debug "Changesets for repository #{url} out-of-sych (use fetch_changesets)" if logger && logger.debug?
      else
          # Get scm revision to update
          scm.revisions('', scm_revision, scm_revision, :with_paths => true).each do |revision|
              changesets.find(:all, :conditions => ["revision = ?", rev]).each do |changeset|
                  changeset.update_attribute :comments, revision.message
                  changeset.update_attribute :committer, revision.author
              end
          end
      end
      end
    end
  end

Run ruby runner "Repository.update_changeset(\"REPOS\",\"REV\")" -e production in a post-revprop=change hook script if the svn repository is local. Otherwise an svn is needed to connect to the Redmine DB directly to perform the above similar task.

Perhaps this is good enough to be included in the next version.
