Subject [jira] [Commented] (COUCHDB-1654) couchdb view sig changed

Benoit Chesneau commented on COUCHDB-1654:
------------------------------------------

Just read the code and it seems that the index file signature is now based on the indexer
module name:

snippet from couch_index_util (l28):

    index_dir(Module, DbName) when is_binary(DbName) ->
        DbDir = "." ++ binary_to_list(DbName) ++ "_design",
        filename:join([root_dir(), DbDir, Module]);
    index_dir(Module, #db{}=Db) ->
        index_dir(Module, couch_db:name(Db)).


    index_file(Module, DbName, FileName) ->
        filename:join(index_dir(Module, DbName), FileName).

Also the path is now based on the module name. So we have two things:

1. signature chane
2. old index file can't be found since the path changed.

Not sure what is the best way to solve that.... For example how do we manage other  index
if we don't change the path accordingly?
