Hello

The thing that i miss the most in modern syslog daemons is the ability to only release the local files without also releasing sockets for syslog servers.

I also saw that this was mentioned earlier on this list[1] but no one seems to have written the patches for this until now.

I have however created patches for this, that may be found at [2]. There are however one problem: In order to figure out which LogPipes that should be closed is now done by comparing logdriver->super.init with the affile_dd_init-function pointer. If it's a match, the LogDriver is a AFFileDestDriver.

A more elegant solution could be to require some larger changes. My suggestion is to include a gboolean "logrotate_release" in the LogDriver, or similar. I have not done any of this, since this would be best to discuss first.

I am also not sure what to do with write_hash in AFFileDestDriver. Should these be reinited as well? If that is the case, i can write the patch required for that as well.

I have spent alot of time reading the code and trying to make the patch fit in with the style of the rest of the code. I hope I succeeded at this.

I also have a git repos with the changes available at [3] and patches for the Ubuntu syslog-ng packages for 6.06 (dapper) and 7.04 (hardy) if it's of interest to anyone.

I have been testing these patches by throwing alot of both USR1 and HUP signals on the running deamon and it seems to behave very well. I'm thinking about rolling them out in production next week. Your opinions are welcome.

Thanks for your contribution. I was also thinking about adding this function, but never got to implement that. So in general I like the function, I think it is very useful. After a quick glimpse on the code, I would hesitate to add it directly though. I hope to get something similar to syslog-ng 3.0. -- Bazsi
