- named_pipe_trick.zip (application/zip)
Attached is win32 implementation of the "named pipe trick". It consists of a Visual Studio 2008 solution that contains two projects, named_pipe_trick (which represents the postmaster) and auxiliary_backend (which represents each auxiliary process). I split the solution into two projects/programs because Windows lacks fork() to make it all happen with a single program. Thoughts? Once I have some buy-in, I'd like to write a patch for the latch code that incorporates monitoring the postmaster using the named pipe trick (for both unix_latch.c and win32_latch.c), plus Heikki's suggestions. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services
