Ondřej Surý	3b6db95e70	Regenerate the DTrace generated files on configure change ... The DTrace generated files were missing dependency on the Makefile, so they didn't get regenerated when ./configure was re-run. This would create problem especially between ./configure --enable-tracing vs ./configure --disable-tracing invocations.	2023-08-23 07:40:20 +02:00
Ondřej Surý	d13ea59a3c	Don't generate the probes.lo on macOS ... The DTrace on macOS only needs header file and the dtrace command doesn't have the -G option. Skip generating the object file on macOS, so the build doesn't fail.	2023-08-23 07:33:50 +02:00
Ondřej Surý	784d055809	Add support for User Statically Defined Tracing (USDT) probes ... This adds support for User Statically Defined Tracing (USDT). On Linux, this uses the header from SystemTap and dtrace utility, but the support is universal as long as dtrace is available. Also add the required infrastructure to add probes to libisc, libdns and libns libraries, where most of the probes will be.	2023-08-21 18:39:53 +02:00
