https://bugzilla.kernel.org/show_bug.cgi?id=43061 URL: http://man7.org/linux/man-pages/man3/resolver.3.html Summary: resolver.3 man page: RES_DEBUG option has effect only if libresolv compiled with DEBUG defined Product: Documentation Version: unspecified Kernel Version: n/a Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: man-pages AssignedTo: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx ReportedBy: kernelbugs@xxxxxxxxxxxx Regression: No The resolver.3 man page's description of the available _res.options flag says: RES_DEBUG Print debugging messages. However, from looking at the libresolv source, I get the impression that if the library was not compiled with "DEBUG" defined then the RES_DEBUG option is silently ignored. Since it appears to be fairly common for the library to be compiled without DEBUG, it seems worth adding a note to the man page mentioning that RES_DEBUG will be ignored in that situation. (As far as I can tell from the build logs, both Debian and Ubuntu build the eglibc packages without DEBUG defined. Is there any easy way to tell on a given running system the whether libresolv was build with or without DEBUG defined?) It might also be worth mentioning the compile-time issue on the resolv.conf.5 page (in the paragraph for the "debug" option). -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
