Proposal to implement get_commit_and_merge_ranges from FS

Hi All,

Problem: Implement get_commit_and_merge_ranges report from a mergeinfo
in FS.

(apr_array_header_t **merge_ranges_list,
 apr_array_header_t **commit_rangelist,
 svn_fs_root_t *root,
 const char *merge_target,
 const char *merge_source,
 svn_revnum_t min_commit_rev,
 svn_revnum_t max_commit_rev,
 svn_mergeinfo_inheritance_t inherit,
 apr_pool_t *pool)

1)Record svn:mergeinfo_added_on_targets in this commit as a transaction
  property. Format of this property's value is serialized hash of
  {/target1 -> '/src1: rR,rX-Y\n
                /src2: rS, rA-B\n',
   /target2 -> '/src1: rR,rX-Y\n
                /src2: rS, rA-B\n',

2)Run something like 'svn_repos_history2' between revisions min_commit_rev
  and max_commit_rev to get commits revs where merge_source has been merged
  to merge_target along with their merge ranges.

Possible problems:
Storing it as revprop makes this data to be mutable, which may be
if someone maliciously write some data that causes hash parser to break.

Possible solutions:
We can maintain this per commit data in a separate place other than the one
where revprops sit. Provide mechanisms to retrieve from this location.

Want to know what others think about this.

With regards
Kamesh Jayachandran
