William Ahern:

  Changelog for the c-ares project

* June 2

- William Ahern:

  I'm not quite sure how this was happening, but I've been seeing PTR queries

  which seem to return empty responses. At least, they were empty when calling

  ares_expand_name() on the record. Here's a patch which guarantees to

  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if

  len was 0, and this was causing strlen() to run past the end of the buffer

  after calling ares_expand_name() and getting ARES_SUCCESS as the return

  value. If q is not greater than *s then it's equal and *s is always

  allocated with at least one byte.

* May 16

- Added ares_getnameinfo which mimics the getnameinfo API (another feature

  /* Nuke the trailing period if we wrote one. */

  if (q > *s)

    *(q - 1) = 0;

  else

    *q = 0; /* zero terminate */

  return ARES_SUCCESS;
