It is very good!
But, i create validation function and see error:
Error: EXIT
{{badmatch,[]},
[{couch_query_servers,new_process,3,
[{file,"couch_query_servers.erl"},{line,472}]},
{couch_query_servers,lang_proc,3,
[{file,"couch_query_servers.erl"},{line,462}]},
{couch_query_servers,handle_call,3,
[{file,"couch_query_servers.erl"},{line,322}]},
{gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,585}]},
{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,239}]}]}
I am not understand Erlang code, and not see error details.
You have it working?
In /etc/couchdb/local.ini i added
[native_query_servers]
erlang = {couch_native_process, start_link, []}
Currently, this is possible only via native Erlang query server:
fun(NewDoc, OldDoc, {UserCtx}, SecObj) ->
DbName = couch_util:get_value(<<"db">>, UserCtx),
{ok, Db} = couch_db:open_int(DbName, [{user_ctx, UserCtx}]),
{ok, Info} = couch_db:get_db_info(Db),
DiskSize = couch_util:get_value(disk_size, Info),
case DiskSize < 100000 of %% ~100KB
true ->
ok;
false ->
throw({[{<<"forbidden">>, <<"quota limit reached">>}]})
end,
1
end.

Hello.
Can I get information about the database as a function of
validate_doc_update? For example, to find out the size of the database or
the number of documents.
Example:
function(newDoc, oldDoc, userCtx) {
if ( thisDb.disk_size > 1000 ) throw({forbidden : 'you have exceeded the
limit'});
}
It is possible?
Thanks.
