When autoconf was checking for libuv features, the LIBUV_CFLAGS was not
added to CFLAGS and LIBUV_LIBS to LIBS which resulted in false
negatives.
Use AX_SAVE_FLAGS and AX_RESTORE_FLAGS to temporarily add LIBUV_CFLAGS
and LIBUV_LIBS to their respective variables.
When there is no time in a key file, `dnssec-settime` will print
"UNSET", but to unset a time the user must specify "none" or "never".
This change allows "unset" or "UNSET" as well as "none" or "never".
The "UNSET" output remains the same to avoid compatibility problems
with wrapper scripts.
I have also re-synchronized the "Timing Options" sections of the man
pages.
The dns_message_gettempname(), dns_message_gettemprdata(),
dns_message_gettemprdataset(), and dns_message_gettemprdatalist() always
succeeds because the memory allocation cannot fail now. Change the API
to return void and cleanup all the use of aforementioned functions.
7249bad7 introduced the -c option to stat(1) command, but BSD systems
do not know about it. Replace the stat(1) command with a PERL script
that achieves the same.
Why PERL? For consistency purposes, there are more places in the
system test where we use the same method.
Check that the recursing client count is above a reasonable
minimum, as well as below a maximum, so that we can detect
bugs that cause recursion to fail too early or too often.
The ns_statscounter_recursclients counter was previously only
incremented or decremented if client->recursionquota was non-NULL.
This was harmless, because that value should always be non-NULL if
recursion is enabled, but it made the code slightly confusing.
The fetchlimit test depends on a resolver continuing to try UDP
and timing out while the client waits for resolution to succeed.
but since commit bb990030 (flag day 2020), a fetch will always
switch to TCP after two timeouts, unless EDNS was disabled for
the query.
This commit adds "edns no;" to server statements in the fetchlimit
resolver, to restore the behavior expected by the test.
Since commit bad5a523c2, when the fetches-per-server quota
was increased or decreased, instead of the value being set to
the newly calculated quota, it was set to the *minimum* of
the new quota or 1 - which effectively meant it was always set to 1.
it should instead have been the maximum, to prevent the value from
ever dropping to zero.
the ADB depends on the resolver, but previously only accessed it
via the view. as view->resolver may now be detached before the ADB
finishes, a shutdown race was possible. attaching to the resolver
directly prevents this.
the request manager has no direct dependency on the
view, so there's no need for a weak reference. remove the
dns_requestmgr_whenshutdown() mechanism since it is no longer
used.
weakly attaching and detaching when creating and destroying the
resolver obviates the need to have a callback event to do the weak
detach. remove the dns_resolver_whenshutdown() mechanism, as it is
now unused.
weakly attaching and detaching the view when creating or destroying
the ADB obviates the need for a whenshutdown callback event to do
the detaching. remove the dns_adb_whenshutdown() mechanism, since
it is no longer needed.
for better object separation, ADB and resolver statistics counters
are now stored in the ADB and resolver objects themsevles, rather than
in the associated view.
it's not necessary to use view attributes to determine whether
the ADB, resolver and requestmgr need to be shut down; checking
whether they're NULL is sufficient.
dns_view_weakattach() and _weakdetach() are used by objects that
are created by the view and need it to persist until they are
destroyed, but don't need to prevent it from being shut down. the
validator can use normal view references instead of weak references.
- eliminate dns_view_flushanddetach(), which was only called from
one place; instead, we now call a function dns_view_flushonshutdown()
which sets the view up to flush zones when it is detached normally
with dns_view_detach().
- cleaned up code in dns_view_create().
there's no longer any need for a parameter to specify whether the
function is called while holding the bucket lock, because all
unlocked uses have been removed.
Add a new parameter to the dst_key structure, mark a key modified if
dst_key_(un)set[bool,num,state,time] is called. Only write out key
files during a keymgr run if the metadata has changed.
Add a test case that triggers a keymgr run that will not trigger any
metadata changes. Ensure that the last status change of the key files
is unmodified.
When attaching to the trampoline, the isc__trampoline_max was access
unlocked. This would not manifest under normal circumstances because we
initialize 65 trampolines by default and that's enough for most
commodity hardware, but there are ARM machines with 128+ cores where
this would be reported by ThreadSanitizer.
Add locking around the code in isc__trampoline_attach(). This also
requires the lock to leak on exit (along with memory that we already)
because a new thread might be attaching to the trampoline while we are
running the library destructor at the same time.
After removing the isc_task_onshutdown(), the isc_task_shutdown() and
isc_task_destroy() became obsolete.
Remove calls to isc_task_shutdown() and replace the calls to
isc_task_destroy() with isc_task_detach().
Simplify the internal logic to destroy the task when the last reference
is removed.
The isc_task_onshutdown() was used to post event that should be run when
the task is being shutdown. This could happen explicitly in the
isc_test_shutdown() call or implicitly when we detach the last reference
to the task and there are no more events posted on the task.
This whole task onshutdown mechanism just makes things more complicated,
and it's easier to post the "shutdown" events when we are shutting down
explicitly and the existing code already always knows when it should
shutdown the task that's being used to execute the onshutdown events.
Replace the isc_task_onshutdown() calls with explicit calls to execute
the shutdown tasks.
Commit 24961f6068 introduced the concept
of post-merge pipelines. These were used to build documentation after
each merge to any of the maintained branches, to allow up-to-date
documentation to be subsequently published on the bind.isc.org
microsite. As the latter no longer downloads documentation from GitLab,
instead linking to Read the Docs for all currently maintained branches,
post-merge pipelines have become redundant since running the
"autoreconf" and "docs" jobs after each merge is not necessary any more.
Drop the "release_branch_triggering_rules" YAML anchor and revert to
default triggering rules for the "autoconf" and "docs" jobs, effectively
preventing pipelines from being created after each merge to any of the
maintained branches.
Building documentation for Automake-based BIND 9 versions does not
require running "make all" beforehand. Drop ccache setup code from the
definitions of GitLab CI jobs building documentation as it is redundant.
The bind.isc.org microsite no longer downloads documentation from
GitLab, instead linking to Read the Docs for all currently maintained
branches. This makes it redundant to trigger GitLab Pages pipelines
after each merge to any of the maintained branches. Revert changes
introduced by commit 31bde118db: remove
the "push:docs" job along with the "push" stage it is associated with
and revert artifact expiry time for the "docs" job to the default value.
Remove the line "This address must appear in the secondary server’s
parental-agents zone clause". This line is a copy paste error from
notify-source.
Rewrap.
