* Persist info about subresources on pages for DNS pre-resolutionjar@chromium.org2009-02-171-0/+46
| | | | | | | | | | | | | | | | | | | | | The DNS pre-resolution system already "learns" what domains are commonly needed when rendering sub-resources of a page at a given domain. This patch saves (some of) the information learned into a persistent pref, and restores it on startup. For now, I put in a wimpy pruning of the list each time I save, so that the list will not grow endlessly from session to session. I probably need a better pruning algorithm, such as one that prunes after a given amount of time, rather than only during shutdown. For now, this should get a lot of nice results, and provide slightly larger than needed lists to users that have long lived sessions, which is similar to the current performance, where I didn't persist any info, and only pruned (actually discarded) all learned info at shutdown. r=mbelshe Review URL: http://codereview.chromium.org/21374 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@9912 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | | | | | | - remove slave threads and use HostResolver in asynchronous mode instead (while still limiting number of concurrent lookups) - make the implementation portable and make DnsMaster unit test compile and pass on Linux - add more tests to DnsMaster unit test to simulate various shutdown scenarios, concurrent lookups, and to verify that we don't exceed our limit of concurrent lookup requests) - remove some tests which relied on specifics of slaves' inner working Bonus: shutdown is almost instant now, no need to have a timeout.

* Adaptively identify URL subresources and pre-resolve hosts via DNSjar@google.com2008-11-061-60/+190
| | | | | | | | | | | | | | | | | | | | Use the HTTP "referer" header to identify subresources used during a page load. Store that info, and use it when next visiting the referenced hosts to pre-resolve the (probably) needed subresources. This set of changes will surely evolve as we see how it plays out on broader distribution (via histogram measurments), but this should be the foundation of the change. In design specs, this was previously referred to as "adaptive correlated DNS prefetching." r=mbelshe Review URL: http://codereview.chromium.org/9168 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@4929 0039d316-1c4b-4281-b951-d872f2087c98

I also made a few other tweaks to PlatformThread, such as eliminating the Current() method which appears to be unused. The operator==() is also unused, so I killed it as well.
