Patches

A getpeereid system call allows local-domain servers to obtain client credentials. Apply these patches in the base directory of your source tree, typically /usr/src:

Make multilog handle SIGHUP by rotating log files at the first opportunity. NB: The rotation is not immediate; rotation occurs at the end of the next line processed by multilog. Apply this patch in your daemontools source directory.

This patch is obsolete as of daemontools-0.75! The daemontools-0.75 multilog program offers a similar forced-rotation feature without a patch (although in response to SIGALRM).

For multilog with daemontools-0.76.

After receiving SIGINT, multilog will continue to read data, but will no longer write them to logs. After receiving SIGHUP, multilog will again write logs as usual. Apply this patch in your daemontools source directory.

When is this patch useful? When you have a high-volume service like dnscache that produces copious logs, the multilog process can limit server performance, by blocking the server while writing and rotating logs. With this patch, you can throw away logs under ordinary operation, reducing the limit on server performance, and retain logs when circumstances warrant analysis. And all without restarting the service.

For publicfile 0.52.

Allow publicfile httpd to handle request URLs with an https scheme. Look for the client IP address in the SSLREMOTEIP environment variable if TCPREMOTEIP is not set. Apply this patch in your publicfile source directory.
