/*
|
|
|
|
|
This is the main class of the proxy.
|
|
|
|
|
From here, several threads are started:
|
|
|
|
|
|
|
|
|
|
- one single instance of the plasmaSwitchboard is generated,
|
|
|
|
|
which itself starts a thread with a plasmaHTMLCache object. This object simply counts
|
|
|
|
|
files sizes in the cache and terminates then.
|
|
|
|
|
It also generates a plasmaCrawlerLoader object, which may itself start
|
|
|
|
|
some more httpc-calling threads to load web pages. They terminate automatically when a page has loaded
|
|
|
|
|
- one serverCore - thread is started, which implements a multi-threaded server.
|
|
|
|
|
The process may start itself many more processes that handle connections.
|
|
|
|
|
- finally, all idle-dependent processes are written in a queue in plasmaSwitchboard
|
|
|
|
|
which are worked off inside an idle-sensitive loop of the main process. (here)
|
|
|
|
|
|
|
|
|
|
On termination, the following must be done:
|
|
|
|
|
- stop feeding of the crawling process because it othervise fills the indexing queue.
|
|
|
|
|
- say goodbye to connected peers and disable new connections. Don't wait for success.
|
|
|
|
|
- first terminate the serverCore thread. This prevents that new cache objects are queued
|
|
|
|
|
- wait that the plasmaHTMLCache terminates (it should be normal that this process already has terminated)
|
|
|
|
|
- then wait for termination of all loader process of the plasmaCrawlerLoader
|
|
|
|
|
- work off the indexing and cache storage queue. These values are inside a RAM cache and would be lost othervise
|
|
|
|
|
- write all settings
|
|
|
|
|
- terminate
