The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
Refactor diagnostic tools code to no longer use:
- isc_socket_recvv()
- isc_socket_sendtov2()
- isc_socket_sendv()
as these functions will be removed shortly.
Emit fatal failures on locale to ACE encoding
Separate idnout support, disable it for libidn2 < 2.0
Add custom path to libidn. Leave default path for multilib support.
Allow turning off IDN input processing by dig option
Improve documentation, fix support in host
Fix configure changes to adjust help text
Use strlcpy with size guard
Improve IDN variants choosing. Fix idn2 function name.
Remove immediate idn_locale_to_ace and idn_ace_to_locale.

4756. [bug] Interrupting dig could lead to an INSIST failure after
certain errors were encountered while querying a host
whose name resolved to more than one address. Change
4537 increased the odds of triggering this issue by
causing dig to hang indefinitely when certain error
paths were evaluated. dig now also retries TCP queries
(once) if the server gracefully closes the connection
before sending a response. [RT #42832, #45159]
4674. [func] "dig +sigchase", and related options "+topdown" and
"+trusted-keys", have been removed. Use "delv" for
queries with DNSSEC validation. [RT #42793]
4549. [func] Added support for the EDNS TCP Keepalive option
(RFC 7828). [RT #42126]
4548. [func] Added support for the EDNS Padding option (RFC 7830).
[RT #42094]
experimental SIT option of BIND 9.10. The following
named.conf directives are avaliable: send-cookie,
cookie-secret, cookie-algorithm and nocookie-udp-size.
The following dig options are available:
+[no]cookie[=value] and +[no]badcookie. [RT #39928]
