All changes in this commit were automated using the command:
shfmt -w -i 2 -ci -bn . $(find . -name "*.sh.in")
By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)
The "uname -o" command is harmful on OpenBSD because this platform does
not know about the "-o" option. It is a permanent failure since system
tests are started with "set -e".
Reduce the number of places that know about the number of IP addresses
required by the system tests, by changing `testsock.pl` to read the
`max` from `ifconfig.sh.in`. This should make the test runner fail
early with a clear message when the interfaces have been set up by an
obsolete script.
Add comments to cross-reference `ifconfig.sh.in`, `testsock.pl`, and
`org.isc.bind.system` to make it easier to remember what needs
updating when an IP address is added.
* make it harder to get the interface numbers wrong by using 'max'
to specify the upper bound of the sequence of interfaces and use 'max'
when calculating the interface number
* extract the platform specific instruction into 'up' and 'down'
and call them from the inner loop so that the interface number is
calculated in one place.
* calculate the A and AAAA address in a single place rather than
in each command
* use /sbin/ipadm on Solaris 2.11 and greater
- Check that an NS in an authority section returned from a forwarder
which is above the name in a configured "forward first" or "forward
only" zone (i.e., net/NS in a response from a forwarder configured for
local.net) is not cached.
- Test that a DNAME for a parent domain will not be cached when sent
in a response from a forwarder configured to answer for a child.
- Check that glue is rejected if its name falls below that of zone
configured locally.
- Check that an extra out-of-bailiwick data in the answer section is
not cached (this was already working correctly, but was not explicitly
tested before).
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
This commit modifies the MTU of the loopback interface on
Linux systems to 1500, so that oversized UDP packets can
trigger EMSGSIZE errors, and tests that named handles
such errors correctly.
Note that the loopback MTU size has not yet been modified
for other platforms.
Some non-POSIX shells, like /bin/csh on FreeBSD, are unable to execute
the config.guess file:
+ /bin/csh /var/tmp/gitlab_runner/builds/YdCaoq4b/0/mnowak/bind9/config.guess
timestamp=2018-02-24: Command not found.
me=config.guess: Command not found.
Unmatched '"'.
When ./configure is run, it attempts to locate a POSIX-compliant shell.
Use the result of that search in the bin/tests/system/ifconfig.sh
script.
It seems that config.guess gets always created in source root, so for
that sake of out-of-tree system test, we should expect the file there
instead of where configure was run.
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
