RetroShare/libretroshare/src/dbase/fimonitor.h
drbob 5e41b21cef Lots of bugfixes and tweaks:
* Switched p3Ranking to share Friends Links as well as own.
 * Modified rankmsgs to contain source id.
 * Fixed up rsNotify, added pqiNotify and global function call to get it.
 * Added notify for Bad Incoming Directory
 * Added Emergency Incoming directory so RS can keep running.
 * Added notify for Bad Packet (connecting to V0.3.X)
 * Added notify for Incomplete Packet Read (not been triggered yet!)
 * added close() to BinInterface, close on pqissl calls reset() 
 * removed exit(1) calls from pqistreamer, replaced with bio->close().
 * Increased Maximum Packet Size for HTML messages.
 * Fixed Online/Offline Message Forwarding. (TEST).
 * Increased DHT bootstrap buckets to 4.
 * Cleaned up much of serialiser debug (was slowing down Mac)
 * Added directory path to File Listings.
 * added ConvertSharedFilePath() so correct local dir can be found.
 * Added ForceDirectoryCheck() and InDirectoryCheck() for file hashing.
 * removed old TMP cache loading.
 * switched off Cache debug.

/******************************************************************************************
* The Local Monitoring Class: FileIndexMonitor.

* This periodically scans the directory tree, and updates any modified directories/files.

*****************************************************************************************/
/******************************************************************************************
STILL TODO:
(1) Implement Hash function.
bool FileIndexMonitor::hashFile(std::string path, FileEntry &fi);
(2) Add Shared directory controls to Monitor.
int FileIndexMonitor::addSharedDirectory(std::path);
int FileIndexMonitor::removeSharedDirectory(std::path);
std::string FileIndexMonitor::findRealRoot(std::string base);
These must be split into <base>/<top> and the mapping saved.
eg: addSharedDirectory("c:/home/stuff/dir1") --> "c:/home/stuff" <-> "dir1"
This code has been written already, and can just be moved over.
FOR LATER:
(2) Port File/Directory lookup code to windoze. (or compile dirent.c under windoze)
(3) Add Load/Store interface to FileIndexMonitor. (later)
(4) Integrate with real Thread/Mutex code (last thing to do)
