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)
