Brad House	a9442bd828	Basic Thread Safety (#636 ) c-ares does not have any concept of thread-safety. It has always been 100% up to the implementor to ensure they never call c-ares from more than one thread at a time. This patch adds basic thread-safety support, which can be disabled at compile time if not desired. It uses a single recursive mutex per channel, which should be extremely quick when uncontested so overhead should be minimal. Fixes Bug: #610 Also sets the stage to implement #611 Fix By: Brad House (@bradh352)	1 year ago
Brad House	cafe6b37db	Add DNS record manpages (#615 ) The new DNS record parser and writer needs manpages. This PR implements those. Fix By: Brad House (@bradh352)	1 year ago
Brad House	0cc570eabe	Implement ares_reinit() to reload system configuration into existing channel (#614 ) This PR implements ares_reinit() to safely reload a channel's configuration even if there are existing queries. This function can be called when system configuration is detected to be changed, however since c-ares isn't thread aware, care must be taken to ensure no other c-ares calls are in progress at the time this function is called. Also, this function may update the open file descriptor list so care must also be taken to wake any event loops and reprocess the list of file descriptors.

Basic Thread Safety (#636 )

c-ares does not have any concept of thread-safety. It has always been 100% up to the implementor to ensure they never call c-ares from more than one thread at a time. This patch adds basic thread-safety support, which can be disabled at compile time if not desired. It uses a single recursive mutex per channel, which should be extremely quick when uncontested so overhead should be minimal.

Fixes Bug: #610

Also sets the stage to implement #611
