|
|
// A high-level interface for client-initiated HTTP requests.
|
|
|
|
// GUI_HTTP represents a "channel" for doing a sequence of HTTP ops,
|
|
// possibly to different servers.
|
|
// There's no queuing:
|
|
// if you call do_rpc() while an op is in progress, you get an error.
|
|
// You must call poll() periodically to make things work.
|
|
//
|
|
// GUI_HTTP_OP is base class for various types of ops.
|
|
// Each instance has a pointer to a particular GUI_HTTP.
|
|
// When the op is completed or failed, its handle_reply() is called
|
|
//
|
|
// The set of GUI_HTTPs:
|
|
// - one for each GUI RPC connection
|
|
// GUI_HTTP_OPs that use this channel:
|
|
// GUI_RPC_CONN::get_project_config_op
|
|
// GUI_RPC_CONN::lookup_account_op
|
|
// GUI_RPC_CONN::create_account_op
|
|
//
|
|
// - one for the client itself
|
|
// GUI_HTTP_OPs that use this channel:
|
|
// CLIENT_STATE::lookup_website_op
|
|
// CLIENT_STATE::get_current_version
|
|
// CLIENT_STATE::get_project_list
|
|
// CLIENT_STATE::acct_mgr_op
|
|
// These are all "best effort": if an op is requested while
|
|
// another is in progress, it's OK; it will be retried later.
|
|
//
|
|
// - for each project:
|
|
// a vector of TRICKLE_UP_OPs for that project's alternative trickle URLs.
|
|
// Each one has a pointer to a dynamically allocated GUI_HTTP.
