So we chose to drop c-ares on Mac OS X and instead do what is done for
Windows in hostthre.c: do a threaded getaddrinfo() resolve. To this end, I
genericized the code in hostthre.c to be compilable on both Windows and Mac,
by using macros to abstract away the competing threading idioms. (Despite
certain wrinkles, they are actually quite similar.)
The code now compiles and works properly on OS X and reasonably modern
Linuxes with pthreads. Additionally, I've reworked the configure script so
that it will choose threaded resolve when pthreads are available but c-ares
is not. I've also regression tested the whole thing on Windows XP and above.
Nice work!
I've nothing against adding another name resolving approach as you describe,
as long as it doesn't get "accidentally" enabled by users who thought
otherwise.
As I said in a pervious mail, the exact procedure to get this merged should
get coordinated with Constantine Sapuntzakis and his win32-related fixes of
that same threaded-resolver functionality.
