* Pass the NetworkChangeNotifier to HostResolver.willchan@chromium.org2010-02-041-1/+1
| | | | | | | | | | | | | | | This requires the following refactors: (1) NetworkChangeNotifier moves out of HttpNetworkSession into IOThread. (2) HostResolver gets initialized with NetworkChangeNotifier. (3) NetworkChangeNotifier needs to get passed into HttpCache and HttpNetworkSession (required updating a lot of files). (4) NetworkChangeNotifier is no longer reference counted. It is owned by IOThread. (5) IOThread gains a new struct: Globals. It can only be used on the io thread. (6) ChromeURLRequestContextFactory uses IOThread::Globals to initialize ChromeURLRequest objects with the host resolver and network change notifier.

* Switch on socket late binding - Take 2.willchan@chromium.org2010-01-271-3/+2
| | | | | | | | | | | | | | | Re-enable socket late binding. The mac valgrind errors happened due to threading bugs in test_shell_tests. The ui thread would TearDown() the test object, which deleted the TestURLRequestContext, which eventually deletes the TCPClientSocketPool, which deletes its ConnectJobs. However, those ConnectJobs might be running simultaneously on the io thread. Therefore, we have a race condition. This change fixes that. Histograms for the 4.0.266.0 dev channel release indicate the following changes for late binding: (a) Net.TCPSocketType shows a decrease (from 41.85% to 39.29%) in used of newly connected sockets. Part of this decrease is due to using previously used sockets more often (increase from 58.15% to 58.53%), but is primarily due to being able to use sockets that were connected, but not immediately handed over to a socket request (increased from 0 [not supported without late binding] to 2.18%). (b) Net.SocketIdleTimeBeforeNextUse_ReusedSocket indicates that reused sockets are getting used more quickly than before, with a decrease of mean idle time from 11.65 seconds to 11.34 seconds. (c) Net.Transaction_Connected_Under_10 indicates shows that the mean for time until the first byte of the transaction response decreased from 1585ms to 1481ms. The code change deletes the old non socket late binding code paths, cleaning up the code significantly. It also deletes duplicated tests in ClientSocketPoolBase which covered both pathways. A TCPClientSocketPool test had to be updated as well. BUG=http://crbug.com/30354.

* Control the amount of time to leave an unused socket idle before closing it.willchan@chromium.org2009-08-291-0/+2
| | | | | | | | | | This adds constructor arguments for socket idle timeouts. This allows me to control it for testing, and also makes it possible to run experiments on how long to enable it for. Currently I've set the timeout for unused sockets to 10 seconds, since that will cover 90% of the TCP RSTs we're seeing. We can probably increase this, but I'm waiting on histogram data to decide what to change it to.

* Make ClientSocketPool/ClientSocketPoolBase/ClientSocketHandle more generic.willchan@chromium.org2009-08-141-13/+14
| | | | | | | | | | | | | | | This is in preparation for creating an SSLClientSocketPool. ClientSocketPoolBase is now templated. Most of the implementation has moved to ClientSocketPoolBaseHelper which is not templated. In order to make this possible, ClientSocketPoolBaseHelper's internal data structures do not use the full concrete Request type, but rather use a pointer to Request. ClientSocketPoolBase takes a SocketParams as a template argument, primarily to allow RequestSocket to take a templated parameter that contains all the information necessary to connect the socket (be it TCP or SSL or whatever). ClientSocketPool::RequestSocket() and ClientSocketHandle::Init() have been templated as well to handle this case. I've left adding run-time type safety checks as a TODO.
