Class: GitDS::StageMemIndex

Inherits:

StageIndex

• Object
• Grit::Index
• Index
• StageIndex
• GitDS::StageMemIndex

Defined in:

lib/git-ds/index.rb

Overview

In-memory staging index.

This replaces the StageIndex#build method with a nop, so that the index is not written to disk.

This is primarily useful in transactions or in methods such as Database#batch. Keepin the tree in-memory as long as necessary reduces disk writes and speeds up bulk insert/delete operations.

Instance Method Details

#build ⇒ Object

Return the sha of the stage index on disk. This DOES NOT synchronize the in-memory index with the on-disk index.

# File 'lib/git-ds/index.rb', line 248

def build
  return @sha
end

#force_sync ⇒ Object

Force a sync-to-disk. This is used by batch mode to ensure a sync.

# File 'lib/git-ds/index.rb', line 261

def force_sync
  self.read_tree(self.write)
  @repo.exec_in_git_dir { `git read-tree #{@sha}` }
end

#sync ⇒ Object

Replace standard sync with a no-op.

# File 'lib/git-ds/index.rb', line 255
