/trunk/include/asterisk/dns_core.h <https://reviewboard.asterisk.org/r/4474/#comment25268> First off, apologies for bringing this up now rather than earlier, but I did not think of this until over this past weekend. The main reason that ast_dns_resolve_async() returns an ast_dns_query is so that the query can be canceled by calling ast_dns_resolve_cancel(). The problem is that there is nothing that prevents the caller of ast_dns_resolve_async() from doing unwanted operations such as adding DNS results/records, or attempting to read results from the query while an async thread is currently writing them. What I propose here is returning something other than an ast_dns_query from this function. The structure returned from ast_dns_resolve_async() could be passed to ast_dns_resolve_cancel(), and that's it. This would be similar to how ast_dns_resolve_recurring() works. - Mark Michelson On March 16, 2015, 2:33 p.m., Joshua Colp wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
