// This file is a part of ThreadSanitizer (TSan), a race detector.

//
|
|
// This file handles synchronization via IO.
|
|
// People use IO for synchronization along the lines of:
|
|
//
|
|
// int X;
|
|
// int client_socket; // initialized elsewhere
|
|
// int server_socket; // initialized elsewhere
|
|
//
|
|
// Thread 1:
|
|
// X = 42;
|
|
// send(client_socket, ...);
|
|
//
|
|
// Thread 2:
|
|
// if (recv(server_socket, ...) > 0)
|
|
// assert(X == 42);
|
|
//
|
|
// This file determines the scope of the file descriptor (pipe, socket,
|
|
// all local files, etc) and executes acquire and release operations on
|
|
// the scope as necessary. Some scopes are very fine grained (e.g. pipe
|
|
// operations synchronize only with operations on the same pipe), while
|
|
// others are corse-grained (e.g. all operations on local files synchronize
|
|
// with each other).
