From f2bac9f9d5b9956969ddd25a54bc636b82f6923e Mon Sep 17 00:00:00 2001 From: Kotresh H R Date: Thu, 13 Feb 2014 23:53:27 +0530 Subject: features/libgfchangelog: APIs to process history changelogs. 1. Create directories in following fashion for history API's usage when consumer is registered with libgfchangelog shared library through gf_changelog_register. scratch_dir/.history scratch_dir/.history/.current scratch_dir/.history/.processed scratch_dir/.history/.processing 2. Added new file 'gf-history-changelog.c' and following APIs are provided for consumers to process history changelogs. 1. gf_history_changelog_scan: Move processed history changelog file from .processing to .processed 2. gf_history_changelog_next_change: Return the next history changelog file entry. Zero means all history chanelogs are consumed. 3. gf_history_changelog_done: Scan .processing directory and generate a list of change entries. 4. gf_history_changelog_start_fresh: For a set of changelogs, start from the begining. NOTE: Though this patch provides above funcationalities. It is considered functionally full with the patch (http://review.gluster.org/#/c/6930/).
