- // NOLINT(build/header_guard)
- // This is the list of load states and their values. For the enum values,
- // include the file "net/base/load_states.h".
- //
- // Here we define the values using a macro LOAD_STATE, so it can be
- // expanded differently in some places (for example, to automatically
- // map a load flag value to its symbolic name).
- // This is the default state. It corresponds to a resource load that has
- // either not yet begun or is idle waiting for the consumer to do something
- // to move things along (e.g., the consumer of an URLRequest may not have
- // called Read yet).
- LOAD_STATE(IDLE, 0)
- // When a socket pool group is below the maximum number of sockets allowed per
- // group, but a new socket cannot be created due to the per-pool socket limit,
- // this state is returned by all requests for the group waiting on an idle
- // connection, except those that may be serviced by a pending new connection.
- LOAD_STATE(WAITING_FOR_STALLED_SOCKET_POOL, 1)
- // When a socket pool group has reached the maximum number of sockets allowed
- // per group, this state is returned for all requests that don't have a socket,
- // except those that correspond to a pending new connection.
- LOAD_STATE(WAITING_FOR_AVAILABLE_SOCKET, 2)
- // This state indicates that the URLRequest delegate has chosen to block this
- // request before it was sent over the network. When in this state, the
- // delegate should set a load state parameter on the URLRequest describing
- // the nature of the delay (i.e. "Waiting for <description given by
- // delegate>").
- LOAD_STATE(WAITING_FOR_DELEGATE, 3)
- // This state corresponds to a resource load that is blocked waiting for
- // access to a resource in the cache. If multiple requests are made for the
- // same resource, the first request will be responsible for writing (or
- // updating) the cache entry and the second request will be deferred until
- // the first completes. This may be done to optimize for cache reuse.
- LOAD_STATE(WAITING_FOR_CACHE, 4)
- // This state was used to wait for access to a resource in the AppCache but
- // AppCache is no longer supported.
- LOAD_STATE(OBSOLETE_WAITING_FOR_APPCACHE, 5)
- // This state corresponds to a resource being blocked waiting for the
- // PAC script to be downloaded.
- LOAD_STATE(DOWNLOADING_PAC_FILE, 6)
- // This state corresponds to a resource load that is blocked waiting for a
- // proxy autoconfig script to return a proxy server to use.
- LOAD_STATE(RESOLVING_PROXY_FOR_URL, 7)
- // This state corresponds to a resource load that is blocked waiting for a
- // proxy autoconfig script to return a proxy server to use, but that proxy
- // script is busy resolving the IP address of a host.
- LOAD_STATE(RESOLVING_HOST_IN_PAC_FILE, 8)
- // This state indicates that we're in the process of establishing a tunnel
- // through the proxy server.
- LOAD_STATE(ESTABLISHING_PROXY_TUNNEL, 9)
- // This state corresponds to a resource load that is blocked waiting for a
- // host name to be resolved. This could either indicate resolution of the
- // origin server corresponding to the resource or to the host name of a proxy
- // server used to fetch the resource.
- LOAD_STATE(RESOLVING_HOST, 10)
- // This state corresponds to a resource load that is blocked waiting for a
- // TCP connection (or other network connection) to be established. HTTP
- // requests that reuse a keep-alive connection skip this state.
- LOAD_STATE(CONNECTING, 11)
- // This state corresponds to a resource load that is blocked waiting for the
- // SSL handshake to complete.
- LOAD_STATE(SSL_HANDSHAKE, 12)
- // This state corresponds to a resource load that is blocked waiting to
- // completely upload a request to a server. In the case of a HTTP POST
- // request, this state includes the period of time during which the message
- // body is being uploaded.
- LOAD_STATE(SENDING_REQUEST, 13)
- // This state corresponds to a resource load that is blocked waiting for the
- // response to a network request. In the case of a HTTP transaction, this
- // corresponds to the period after the request is sent and before all of the
- // response headers have been received.
- LOAD_STATE(WAITING_FOR_RESPONSE, 14)
- // This state corresponds to a resource load that is blocked waiting for a
- // read to complete. In the case of a HTTP transaction, this corresponds to
- // the period after the response headers have been received and before all of
- // the response body has been downloaded. (NOTE: This state only applies for
- // an URLRequest while there is an outstanding Read operation.)
- LOAD_STATE(READING_RESPONSE, 15)
