When running all the system tests, output from a test is sent to a
test.output file in the test directory. These are combined in to
systests.output when the run finishes.
(cherry picked from commit 055e5be9fd)
Add more information on running the tests, together with a section
on how the tests are organised, aimed at new developers.
(cherry picked from commit af005cdbcf)
Tidy up the stop/start files and make switch usage consistent. Also
tidy up the various "clean" targets in the Makefile.
(cherry picked from commit b24c2e11d8)
Miscellaneous tidying up of run management. The most significant
change is that "runall.sh" now runs _all_ the tests, even the
ones that can run in parallel. runsequential.sh is the script
to run tests that have not been converted to parallel running.
(cherry picked from commit 32fe6f7682)
Some tests use more ports than just the query and control ports.
Each test that can run in parallel with other tests is now assigned
a unique block of 10 ports.
(cherry picked from commit e0ff77f9d3)
Currently these tests are allow_query, rpzrecurse and serve-stale
1. Function to copy files and set port numbers renamed from copy_config
to copy_setports, as this is used to change the ports in Perl and Python
test scripts as well.
2. Changes to rpzrecurse/tests.sh to handle two calls to getopts (one to
parse port numbers, the other to parse rpzrecurse-specific options). Also
fixed various commands to use correct ports.
3. Updates to "clean.sh" scripts to ensure that all files created in the
test are removed.
(cherry picked from commit 78f2b9ca01)
Via an intermediate make file, tests that have been modified to be able
to run in parallel are assigned unique query and control port numbers
(other than 5300 and 9953 respectively). Tests that have not yet been
modified all use ports 5300 and 9953, so must be run sequentially.

4892. [bug] named could leak memory when "rndc reload" was invoked
before all zone loading actions triggered by a previous
"rndc reload" command were completed. [RT #47076]
Remove a block of code which dates back to commit 8a2ab2b920, when
dns_zone_asyncload() did not yet check DNS_ZONEFLG_LOADPENDING.
Currently, no race in accessing DNS_ZONEFLG_LOADPENDING is possible any
more, because:
- dns_zone_asyncload() is still the only function which may queue
zone_asyncload(),
- dns_zone_asyncload() accesses DNS_ZONEFLG_LOADPENDING under a lock
(and potentially queues an event under the same lock),
- DNS_ZONEFLG_LOADPENDING is not cleared until the load actually
completes.
Thus, the rechecking code can be safely removed from zone_asyncload().
Note that this also brings zone_asyncload() to a state in which the
completion callback is always invoked. This is required to prevent
leaking memory in case something goes wrong in zone_asyncload() and a
zone table the zone belongs to is indefinitely left with a positive
reference count.
Code handling cancellation of asynchronous zone load events was likely
copied over from other functions when asynchronous zone loading was
first implemented in commit 8a2ab2b920. However, unlike those other
functions, asynchronous zone loading events currently have no way of
getting canceled once they get posted, which means the aforementioned
code is effectively dead. Remove it to prevent confusion.
zone_load() is not always synchronous, it may only initiate an
asynchronous load and return DNS_R_CONTINUE, which means zone loading
has not yet been completed. In such a case, zone_asyncload() must not
clear DNS_ZONEFLG_LOADPENDING immediately and leave that up to
zone_postload().
While this is not an issue in named, which only calls
dns_zone_asyncload() from task-exclusive mode, this function is exported
by libdns and thus may in theory be concurrently called for the same
zone by multiple threads. It also does not hurt to be consistent
locking-wise with other DNS_ZONEFLG_LOADPENDING accesses.
