Dear List, My very first post in the dev mailing list, as I am going to spend much more time in my personal OpenSim.
I have written some code quite a while back and wanted to share my thoughts and start a discussion about it. *Signal Handling* Currently, OpenSim services do NOT support POSIX signal handling when POSIX is available. This support is available on pretty much any *nix platform including MacOS X. Windows does NOT support POSIX period. In Mono, POSIX signal handling can be easily accomplished using the mono.posix.dll. I have currently implemented nothing more but the TERM signal, to ensure the services are properly stopped, instead of simply killed on the spot. This means that the service actually goes through the shutdown procedure (if any). The next goal would be to implement HUP to reload the service. My current problem, is that the code is just there. No ifdef statements, nothing. I simply lack the knowledge in .NET/Mono to exclude the code from an environment that does not include posix. Some pointers in the right direction would be much appreciated. *Discussion* When creating services, there must be an easy way to start/stop them. Especially on *nix this comes in handy. Shoving the word "exit" or "shutdown" into the service cli is just not working all the time and is error prone. Adding POSIX signal handling would be considered "standard" in such services. The fact that MS Windows does not support POSIX signals is simply disregarded. The equivalent on Windows would be to have a service binary that runs the OpenSim services (I think that already exists). There aren't that many other "standard" solutions to the same problem, and although signal handling wouldn't work on ONE platform (ONE being Windows), it is guaranteed to work on ALL others (ALL being the *nix ones lol). So to start the discussion, here are some questions: 1. Is there any interest in this code? With this I mean: would we want POSIX signal handling or will we try to develop a different way to solve the same problem? 2. If there is any interest, who do I send my patch to? With kind regards, Rory Slegtenhorst rory dot slegtenhorst at gmail dot com
