-// Functions related to the sending the setup pings. The functionality provided
-// by this class is used in by install, handoff, and update features.
-// This is an overview of how the setup pings work.
-// In the case of install, the execution flow includes the following steps:
-// elevation if needed, setting up Omaha, and installing the applications
-// specified in the tag.
-// The code guarantees that an EVENT_INSTALL_COMPLETE(2) ping for Omaha is sent
-// in all cases, except trivial errors that may happen before the execution flow
-// reaches the Install function.
-// A EVENT_INSTALL_COMPLETE(2) ping for the apps is also sent in all cases.
-//
-// Where the code fails affects how the pings are generated and sent, as
-// following:
-// * if the elevation was required but the elevated process failed to run,
-//   then both pings are sent from the medium integrity /install
-//   process.
-// * if the Omaha setup code ran but it errored out or the handoff failed to
-//   launch, then both pings are sent from the /install process or the
-//   elevated /install process if elevation was successful. The pings will be
-//   split in two different http transactions in the case setup completed
-//   successfully but it failed to handoff.
-// * if the /handoff process launched but an error occured in the handoff
-//   process itself, then the Omaha "2" ping is sent from the /install process
-//   and the apps "2" ping is sent from the /handoff process.
-//   The apps ping is only sent if the handoff code did not proceed far enough
-//   to create a bundle of  applications. Beyond that point, the bundle takes
-//   over the responsibility of sending "2" pings for each app in the bundle.
-//
-// There is an IPC mechanism between /install and /handoff processes based
-// on detected input idle to avoid overlapping error handling and
-// displaying redundant error messages in different processes. Usually ping
-// handling, error handling, and displaying error UI is done in the same layer.
-// When an error happens in the chain of /install, elevated install,
-// and /handoff  processes, then UI is displayed by one of these processes only
-// if the child process did not display UI. Since UI is displayed in the
-// /handoff process in both the success and error cases, this information can't
-// be useful to handle the pings, therefore pings only rely on a weaker
-// guarantee, which is whether the child process has launched or not.
-
-// TODO(omaha): unify the install and bundle pings mechanisms. There is
-// no facility to cancel the install pings in the current implementation.
-
-// TODO(omaha): use a pimpl to avoid the dependency on UpdateRequest.
