[PATCH fifo 4/8] Cygwin: FIFO: improve EOF detection

Add a hit_eof method that tries to detect whether any clients are connected. Before concluding that there are none, it gives the listen_client thread time to update the client data. --- winsup/cygwin/fhandler.h | 1 + winsup/cygwin/fhandler_fifo.cc | 21 - 2 files chang

[PATCH fifo 2/8] Cygwin: FIFO: allow multiple writers

Introduce a 'fifo_client_handler' structure that can be used by a reader to communicate with a writer using an instance of the named pipe. An fhandler_fifo opened for reading creates a thread that does the following: - maintains a list of fifo_client_handlers - listens for_clients trying to con

[PATCH fifo 8/8] Cygwin: FIFO: update select

Add static functions peek_fifo, thread_fifo, start_thread_fifo, and fifo_cleanup to select.cc. These are based on the corresponding pipe functions, the main difference being that peek_fifo loops through the connected clients to see if any of them have data available for reading. Add the fhandler_

Currently a FIFO can have only one writer. A second attempt to open the FIFO for writing blocks while fhandler_fifo::open waits for the read_ready event to be signalled. This patch series tries to fix the problem by having the reader open multiple instances of the Windows named pipe underlying th

[PATCH fifo 1/8] Cygwin: FIFO: stop using overlapped I/O

Make fhandler_fifo a derived class of fhandler_base instead of fhandler_base_overlapped. Replace the create_pipe macro, which is based on fhandler_pipe::create, by new create_pipe and open_pipe methods. These use NT functions instead of Win32 functions. Replace fifo_name by get_pipe_name, which r
