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)
(manually replayed commit 4cb8b13987)
The old name "common" clashes with the convention of system test
directory naming. It appears as a system test directory, but it only
contains helper files.
To reduce confusion and to allow automatic detection of issues with
possibly missing test files, rename the helper directory to "_common".
The leading underscore indicates the directory is different and the its
name can no longer be confused with regular system test directories.
(cherry picked from commit 168dba163c)
The changes were mostly done with sed:
find . -name '*.sh' | xargs sed -i 's/`\([^`]*\)`/$(\1)/g'
There have been a few manual changes where the regex wasn't sufficient
(e.g. backslashes inside the `...`) or wrong (`...` referring to docs or
in comments).

Ensure handling of return code from previous command doesn't cause the
script to halt if that code is non-zero when running with `set -e`.
(cherry picked from commit 837c190d9e)
Ensure all shell system tests are executed with the errexit option set.
This prevents unchecked return codes from commands in the test from
interfering with the tests, since any failures need to be handled
explicitly.
(cherry picked from commit 01bc805f89)
In order to run the shell system tests, the pytest runner has to pick
them up somehow. Adding an extra python file with a single function
for the shell tests for each system test proved to be the most
compatible way of running the shell tests across older pytest/xdist
versions.
Modify the legacy run.sh script to ignore these pytest-runner specific
glue files when executing tests written in pytest.

(manually added host/tests_sh_host.py, tkey/tests_sh_tkey.py on top)
DSCP has not been fully working since the network manager was
introduced in 9.16, and has been completely broken since 9.18.
This seems to have caused very few difficulties for anyone,
so we have now marked it as obsolete and removed the
implementation.
To ensure that old config files don't fail, the code to parse
dscp key-value pairs is still present, but a warning is logged
that the feature is obsolete and should not be used. Nothing is
done with configured values, and there is no longer any
range checking.

When a target server is unreachable, the varying network conditions may
cause different ICMP message (or no message). The host unreachable
message was discovered when attempting to run the test locally while
connected to a VPN network which handles all traffic.
Extend the dig output check with "host unreachable" message to avoid a
false negative test result in certain network environments.
(cherry picked from commit 1e7d832342)
There are existing tests for simulating timeouts, read errors, and
refused connecion errors. Implement also "network unreachable"
simulation.
Use "fixed" string search mode `-F` for `grep` in more places where
it is appropriate to do so.
(cherry picked from commit 626fbf325e)
In `send_udp()` and `launch_next_query()` functions, when calling
`dighost_printmessage()` to print detailed information about the
sent query, dig always prints the data of the first query in the
lookup's queries list.
The first query in the list can be already finished, having its handles
freed, and accessing this information results in assertion failure.
Print the current query's information instead.
(cherry picked from commit f831e758d1)
In recv_done(), when dig decides to start the lookup's next query in
the line using `start_udp()` or `start_tcp()`, and for some reason,
no queries get started, dig doesn't cancel the lookup.
This can occur, for example, when there are two queries in the lookup,
one with a regular IP address, and another with a IPv4 mapped IPv6
address. When the regular IP address fails to serve the query, its
`recv_done()` callback starts the next query in the line (in this
case the one with a mapped IP address), but because `dig` doesn't
connect to such IP addresses, and there are no other queries in the
list, no new queries are being started, and the lookup keeps hanging.
After calling `start_udp()` or `start_tcp()` in `recv_done()`, check
if there are no pending/working queries then cancel the lookup instead
of only detaching from the current query.
(cherry picked from commit 7e2f50c369)
Rework the "ans8" server in the "digdelv" system test to support various
modes of operations using a control channel.
The supported modes are:
1. `silent` (do not respond)
2. `close` (UDP: same as `silent`; TCP: also close the connection)
3. `servfail` (always respond with `SERVFAIL`)
4. `unstable` (constantly switch between `silent` and `servfail`)
Add multiple tests to check the handling of both TCP and UDP socket
error scenarios in dig/host.
(cherry picked from commit 03697f1bcc)
Add a test to check whether dig tries the next query/server after
a connection error.
Add a test to check whether dig tries the next query/server after
a one or more (default is 3) connection/request timeouts.
(cherry picked from commit e8a64d0cbe)
This test ensures that `dig` retries with another attempt after a
timed-out request, and that it does not crash when the retried
request returns a SERVFAIL result. See [GL #3020] for the latter
issue.
(cherry picked from commit 3ec5d2d6ed)
- Removed all code that only runs under CYGWIN, and made all
code that doesn't run under CYGWIN non-optional.
- Removed the $TP variable which was used to add optional
trailing dots to filenames; they're no longer optional.
- Removed references to pssuspend and dos2unix.
- No need to use environment variables for diff and kill.
- Removed uses of "tr -d '\r'"; this was a workaround for
a cygwin regex bug that is no longer needed.
(cherry picked from commit 1d706f328c)
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.
The digdelv system test has a test case in which stderr was
included in the dig output. When trace logging was in use,
this confused the grep and caused a spurious test failure.
Address the following warnings reported by PyLint 2.10.2:

Added tests to ensure that dig won't retry sending a query over tcp
(+tcp) when a TCP connection is closed prematurely (EOF is read) if
either +tries=1 or retry=0 is specified on the command line.
Now that premature EOF on tcp connections take +tries and +retry into
account, the dig system tests handling TCP EOF with +tries=1 were
expecting dig to do a second attempt in handling the tcp query, which
doesn't happen anymore.
To make the test work as expected +tries value was adjusted to 2, to
make it behave as before after the new update on dig.
The network manager does not support returning UDP datagrams to
clients from unexpected sources; it is therefore not possible for
dig to accept them. The "+[no]unexpected" option has therefore
been removed from the dig command and its documentation.
* the legacy test with -T maxudp512 will just fail, e.g. if the packets
larger than 512 octets are dropped along the path, the proper response
is to fail
* digdelv test was just expecting default server EDNS buffer size to be
4096, the test needed only slight adjustment
The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.
$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.
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
The yamlget.py file was changed in !3311 as part of making the
python code pylint and flake8 compliant. This omitted setting
'item' to 'item[key]' which caused the digdelv yaml tests to fail.
Also, the pretty printing is not really necessary, so remove
the "if key not in item; print error" logic.
The first step in all existing setup.sh scripts is to call clean.sh. To
reduce code duplication and ensure all system tests added in the future
behave consistently with existing ones, invoke clean.sh from run.sh
before calling setup.sh.
The indentation for dumping the master zone was driven by two
global variables dns_master_indent and dns_master_indentstr. In
threaded mode, this becomes prone to data access races, so this commit
converts the global variables into a local per-context tuple that
consist of count and string.
