The isc-config.sh script was introduced before pkg-config as is a purely
historical thing. There are two reason for removal of isc-config.sh scripts:
a) The BIND 9 libraries are now meant to be used only from BIND 9, so there's no
reason to provide convenience script to link with the libraries.
b) Even if that was not the case, we should and would replace the isc-config.sh
with respective pkg-config (.pc) file for every library.
- "--with-geoip" is used to enable the legacy GeoIP library.
- "--with-geoip2" is used to enable the new GeoIP2 library
(libmaxminddb), and is on by default if the library is found.
- using both "--with-geoip" and "--with-geoip2" at the same time
is an error.
- an attempt is made to determine the default GeoIP2 database path at
compile time if pkg-config is able to report the module prefix. if
this fails, it will be necessary to set the path in named.conf with
geoip-directory
- Makefiles have been updated, and a stub lib/dns/geoip2.c has been
added for the eventual GeoIP2 search implementation.
When GNU C Compiler is used on Solaris (11), the Thread Local Storage
is completely broken. The behaviour doesn't manifest when GNU ld is
used. Thus, we need to enforce usage of GNU ld when GNU C Compiler is
the compiler of choice.

The ax_check_openssl m4 macro used OPENSSL_INCLUDES. Rename the
subst variable to OPENSSL_CFLAGS and wrap AX_CHECK_OPENSSL() in
action-if-not-found part of PKG_CHECK_MODULE check for libcrypto.
The libxml2 have previously leaked into the global namespace leading
to forced -I<include_path> for every compilation unit using isc/xml.h
header. This MR fixes the usage making the caller object opaque.
Previously the autoconf script set sysconfdir to /etc and localstatedir to /var
if they were not explicitly set in the ./configure invocation. This MR reverts
the override and make it more in line with default and generally expected
autoconf behavior.
AM_MAINTAINER_MODE macro adds ability to disable rebuilding build file
(Makefile.in, configure, ...) when the source file changes. This is
important in the CI where the timestamps could get skewed and that
triggers the rebuild on every ./configure run.
Pull and use several autoconf archive convenience macros to simplify
configure.ac.
* AX_CHECK_COMPILE_FLAG(FLAG, ...) - check whether given CFLAG works
* AX_CHECK_LINK_FLAG(FLAG, ...) - check whether given LDFLAG works
* AX_CHECK_PREPROC_FLAG(FLAG, ...) - check whether give CPPFLAG works
* AX_SAVE_FLAGS/AX_RESTORE_FLAGS - save and restore *FLAGS
This work cleans up the API which includes couple of things:
1. Make the isc_appctx_t type fully opaque
2. Protect all access to the isc_app_t members via stdatomics
3. sigwait() is part of POSIX.1, remove dead non-sigwait code
4. Remove unused code: isc_appctx_set{taskmgr,sockmgr,timermgr}
Previously, only a message about missing Python was printed, which was
misleading to many users. The new message clearly states that Python
AND PLY is required and prints basic instructions how to install PLY
package.
- "hook" is now used only for hook points and hook actions
- the "hook" statement in named.conf is now "plugin"
- ns_module and ns_modlist are now ns_plugin and ns_plugins
- ns_module_load is renamed ns_plugin_register
- the mandatory functions in plugin modules (hook_register,
hook_check, hook_version, hook_destroy) have been renamed
- temporary kluge! in this version, for testing purposes,
named always searches for a filter-aaaa module at /tmp/filter-aaaa.so.
this enables the filter-aaaa system test to run even though the
code to configure hooks in named.conf hasn't been written yet.
- filter-aaaa-on-v4, filter-aaaa-on-v6 and the filter-aaaa ACL are
still configured in the view as they were before, not in the hook.
