After a failed reload I noticed two problems:
* There was a missing newline in the output of `rndc status` so it
finished "reload/reconfig in progressserver is up and running"
* The "reconfig in progress" note should have said "reconfig failed"
Previously the autoconf script set sysconfdir to /etc and localstatedir to /var
if they were not explicitly set in the ./configure invocation. This MR reverts
the override and make it more in line with default and generally expected
autoconf behavior.
AM_MAINTAINER_MODE macro adds ability to disable rebuilding build file
(Makefile.in, configure, ...) when the source file changes. This is
important in the CI where the timestamps could get skewed and that
triggers the rebuild on every ./configure run.
The differences between two files are very minimal and most of the
code is common. Merge those two files and use #ifdef WIN32 to include
the right bits on Windows.
Using atomic_int_fast64_t variables with atomic functions on x86 does
not cause Visual Studio to report build errors, but such operations
yield useless results. Since the isc_stat_t type is unconditionally
typedef'd to atomic_int_fast64_t, any code performing atomic operations
on isc_stat_t variables is broken in x86 Windows builds. Fix by using
the atomic_int_fast32_t type for isc_stat_t in x86 Windows builds.
BIND 9.11.0 has bumped DNS_CLIENTINFOMETHODS_VERSION and _AGE to
version 2 and 1 in the dlz_minimal.h because a member was addet to the
dnsclientinfo struct. It was found out that the new member is not
used anywhere and there are no accessor functions therefore the change
was reverted.
Later on, it was found out that the revert caused some problems to the
users of BIND 9, and thus this changes takes a different approach by
syncing the values other way around.
The common construct seen in the BIND 9 source is func(isc_mem_t *mctx, ...).
Unfortunately, the dnstest.{h,c} has been using mctx as a global symbol, which
in turn generated a lot of errors when update.c got included in update_test.c.
As a rule of thumb, we should avoid naming global symbols with generic names
(like mctx) and we should prefix them with "namespace" (like dt_mctx).
The CHECK() macro has been defined both in dnstest.h and update.c
files. This has created a conflict between macro definitions when
including both of the files in update_test.c. While the CHECK() macro
is convenient for the tests, it has been really used in just two
files, so the MR moves them into those respective .c files.
lib/dns/tests/update_test was failing on macOS on random occasions. It
turned out this was a linker problem - it preferred isc_stdtime_get()
from libisc instead of the local version in lib/dns/tests/update_test.c.
Fix by including the original .c file in the unit test. This has two
benefits:
a) linking order may no longer cause issues as symbols found in the
same compilation unit are always preferred,
b) it allows writing tests for static functions in lib/dns/update.c.
Pull and use several autoconf archive convenience macros to simplify
configure.ac.
* AX_CHECK_COMPILE_FLAG(FLAG, ...) - check whether given CFLAG works
* AX_CHECK_LINK_FLAG(FLAG, ...) - check whether given LDFLAG works
* AX_CHECK_PREPROC_FLAG(FLAG, ...) - check whether give CPPFLAG works
* AX_SAVE_FLAGS/AX_RESTORE_FLAGS - save and restore *FLAGS
In certain situations (e.g. a named instance crashing upon shutdown in a
system test which involves shutting down a server and restarting it
afterwards), a system test may succeed despite a named crash being
triggered. This must never be the case. Extend run.sh to mark a test
as failed if core dumps or log lines indicating assertion failures are
detected (the latter is only an extra measure aimed at test environments
in which core dumps are not generated; note that some types of crashes,
e.g. segmentation faults, will not be detected using this method alone).
Make the get_named_xfer_stats() helper shell function more precise in
order to prevent it from matching the wrong lines as that may trigger
false positives for the "ixfr" and "xfer" system tests. As an example,
the regular expression responsible for extracting the number of bytes
transmitted throughout an entire zone transfer could also match a line
containing the following string:
transfer of '<zone-name>/IN': sending TCP message of <integer> bytes
However, such a line is not one summarizing a zone transfer.
Also simplify both get_dig_xfer_stats() and get_named_xfer_stats() by
eliminating the need for "echo" statements in them.
