- Update the Agent to use separate control and data pipes and to receive
arbitrary-sized packets. Handle child process creation in the agent.
- Fix bugs in libpconsole:
- Insert a space between the pipe names on the agent command line.
- Don't close the desktop and window station until after connecting
to the agent's pipes.
- Change the format of the pconsole_start_process env parameter from an
array of wide-character-string pointers to a single contiguous block of
memory, like that accepted by CreateProcess.
* Remove obsolete comments and APIs.
* In pconsole.exe, use two threads to handle pconsole<->pty communication.
I use blocking I/O for the pty. For the Win32 pipe to the pconsole
agent, I use overlapped I/O and emulate blocking I/O.
I'm not sure I *have* to open the pipe in overlapped mode. When I last
tried using non-overlapped I/O, I had a problem where a pending read
would block writes (or vice versa). Maybe setting the overlapped
parameter to {Read,Write}File would be sufficient.
My plan now is to integrate the PseudoConsole with Cygwin and MSYS ptys,
with initial focus on Cygwin. I think I'll keep the separate Agent and DLL
binaries, and they'll continue to be native Win32 binaries. I don't want
to have two build systems (qmake vs whatever MSYS/Cygwin uses), and since
I'd like to remove the Qt dependency anyway, I'm trying to switch to
makefiles.
