| * | Cache failed DNS resolutions for 1 second. | eroman@chromium.org | 2009-12-10 | 1 | -4/+8 |
| | | | | | | | | | | | | | | | | | | | This is a very small time to live, since we want to be able to respond quickly when formerly unresolvable names become resolvable. Even such a small time is still useful, since cache misses for unresolvable names can be extremely costly (order of several seconds). For example, in our corp PAC script, the URL's host is resolved 3 times, so: Without caching, total runtime is (2.5 seconds) * 3 --> 7.5 seconds. Whereas with caching it would be: (2.5 seconds) * 1 --> 2.5 seconds This time to live will need to be tuned as part of bug 25472.

| * | Add a mechanism to disable IPv6. | eroman@chromium.org | 2009-10-21 | 1 | -4/+4 |
| | | | | | | | | | | | | | | | | | | | | (1) Adds the ability to specify the address family on a per-request basis. (2) Exposes a --disable-ipv6 flag to chrome that changes the default address family from AF_UNSPEC to AF_INET (same sort of thing Firefox does). (3) Changes the backing datastructure for HostCache:EntryMap and HostResolverImpl::JobMap from a "hash_map" to a "std::map". This was for consistency with other code (when I went to add a custom hash trait, I couldn't find any existing code which was using hashmap for custom keys). (4) Updates about:net-internals to display an address family for the hostcache dump (since it is now a part of the key). This change is in anticipation of turning off IPv6 host resolving in the PAC utility functions (see bug 24641). But it is also a feature addition.

| * | * Avoid doing concurrent DNS resolves of the same hostname in HostResolver. | ericroman@google.com | 2009-06-12 | 1 | -0/+115 |
| * Add a 1 minute cache for host resolves. * Refactor HostResolver to handle multiple requests. * Make HostResolver a dependency of URLRequestContext. operate the HostResolver in async mode for proxy resolver (bridging to IO thread).
