Converted using pandoc 2.14.2-9 on Arch Linux:
$ pandoc --shift-heading-level-by=-1 -f markdown -t rst README.md > doc/arm/build.rst
Plus hand-edit to remove sections other than Building BIND 9, remove
misindentation in section headers, and add a standard copyright header.
Converted using pandoc 2.14.2-9 on Arch Linux:
$ pandoc -f markdown -t rst PLATFORMS.md > PLATFORMS.rst
The pandoc-generated copyright header was subsequently replaced with
usual one for .rst files.
For reproducible builds, we use last modification time of the CHANGES
file. This works pretty well, unless the builds are made in different
timezones.
Use UTC option to date command to make the builds reproducible.
On some systems, the glibc can return 0 instead of cache-line size to
indicate the cache line sizes cannot be determined. This is comment
from glibc source code:
/* In general we cannot determine these values. Therefore we
return zero which indicates that no information is
available. */
As the goal of the check is to determine whether the L1 cache line size
is still 64 and we would use this value in case the sysconf() call is
not available, we can also ignore the invalid values returned by the
sysconf() call.
As far as I can tell, it is some leftover from the times when Sphinx
docs were introduced (commit 9fb6d11abb).
It seems like it is not referenced from anywhere.
Extend the error message displayed when support for DNS over HTTPS is
requested but libnghttp2 is unavailable at build time, in order to help
the user find a way out of such a situation.
The terms "DNS over HTTPS" and "DNS over TLS" should be hyphenated when
they are used as adjectives and non-hyphenated otherwise. Ensure all
occurrences of these terms in the source tree follow the above rule.
(CHANGES and release notes are intentionally left intact.)
Tweak a related ARM snippet, fixing a typo in the process.
If isc_app_run() gets interrupted by a signal, the global 'rndc_task'
variable may already be detached from (set to NULL) by the time the
outstanding netmgr callbacks are run. This triggers an assertion
failure in isc_task_shutdown(). However, explicitly calling
isc_task_shutdown() from rndc code is redundant because it does not use
isc_task_onshutdown() and the task_shutdown() function gets
automatically called anyway when the task manager gets destroyed (after
isc_app_run() returns). Remove the redundant isc_task_shutdown() calls
to prevent crashes after receiving a signal.
rndc_recvdone() is not treating the ISC_R_CANCELED result code as a
request to stop data processing, which may cause a crash when trying to
dereference ccmsg->buffer. Fix by ensuring ISC_R_CANCELED results in an
early exit from rndc_recvdone().
Make sure the logic for handling ISC_R_CANCELED in rndc_recvnonce()
matches the one present in rndc_recvdone() to ensure consistent behavior
between these two sibling functions.
Sometimes the serving a query or two might fail in the test due to the
listeners not being reinitialised on time. This commit makes the test
suite to wait for reconfiguration message in the log file to detect
the time when the reconfiguration request completed.
gnutls-cli is tricky to script around as it immediately closes the
server connection when its standard input is closed. This prevents
simple shell-based I/O redirection from being used for capturing the DNS
response sent over a TLS connection and the workarounds for this issue
employ non-standard utilities like "timeout".
Instead of resorting to clever shell hacks, reimplement the relevant
check in Python. Exit immediately upon receiving a valid DNS response
or when gnutls-cli exits in order to decrease the test's run time.
Employ dnspython to avoid the need for storing DNS queries in binary
files and to improve test readability. Capture more diagnostic output
to facilitate troubleshooting. Use a pytest fixture instead of an
Autoconf macro to keep test requirements localized.
Some operating systems (OpenBSD and DragonFly BSD) don't restrict the
IPv6 sockets to sending and receiving IPv6 packets only. Explicitly
enable the IPV6_V6ONLY socket option on the IPv6 sockets to prevent
failures from using the IPv4-mapped IPv6 address.
