The stack traces weren't logged as the LOG_ALERT priority wasn't enabled
by default. As an alert is intended to be something that must leave a
trace somewhere, and as such, it must not be possible to disable it. For
this reason, it is acceptable to always log the message if the priority is
LOG_ALERT.
Added the -rdynamic linker flag so that all symbols are exported when
linking MaxScale.
As the stack trace is printed in a signal handler, the first attempt
should be to print the stack trace to the standard output. This way the
output is printed before an attempt to use malloc is made when it is
logged to the logfile.
AdressSanitizer is a lightweight memory error detector that instruments at
compile time instead of at execution time. This allows serious memory
errors to be detected without the cost of slowing down the whole program
that often happens when Valgrind is used. It is also easier to enable for
test runs as it is a simple compiler flag.
Moved and renamed the starting and stopping scripts from the REST API
tests to a common directory. This way the MaxCtrl tests can use the same
scripts to start and stop MaxScale.
Also moved the test configuration file into the `test/` directory and
changed some of the default directory locations.
The feedback system wasn't used and was starting to cause problems on
Debian 9 where the libcurl required different version of OpenSSL than what
MaxScale was linked against.
OpenSSL 1.1 supports most of the native threading libraries, including
pthread. This means that only versions before 1.1 need the thread handling
code.
Some additions to config.cc will require a recent version of PCRE2.
The system libraries may not be up to date. The pcre2 source is
bundled with MaxScale anyway, so using it is a simple way of controlling
the library version.
This allows MaxScale to use the PATCH functionality that's only in the
newer versions of the library. It also removes some of the problems that
exist with older systems that don't support all of the options.
The devel package was missing the protocol/mysql.h-file. Also,
added copyright and licence files and a devel-specific description.
The package target is now checked to be one of the recognized ones.
The module configuration directory didn't have a value in the CMake
files. The directory is now also installed by both packages and local
installations.
Converting the README into Markdown format makes it a lot easier to
comprehent. Also cleaned up the formatting.
The 2.0 branch had a broken Travis configuration. Fixed it and changed
links to point to 2.0 branch.
Various older systems use Upstart to control services. MaxScale should
provide both init.d scripts and Upstart configurations for systems that
don't support systemd.
Some of the libraries used by MaxScale are distributed under BSD
licenses. The BSD license requires that the license text is included with
the binary distributions.
Added find_package module for CMake which locates the Jansson libraries
and headers. This will make dependency checking easier and prevents build
failures due to missing dependencies.
The maxavro requires some special libraries which aren't always
available. For this reason, the maxavro library shouldn't be build unless
all libraries are available.
Added FindGSSAPI.cmake which allows the modules to be built only if the
libraries are found.
The log manager header was not included by the GSSAPI modules.
- Headers now to be included as <maxscale/xyz.h>
- First step, no cleanup of headers has been made. Only moving
from one place to another + necessary modifications.
The upgrade process removed the /var/lib/maxscale directory as the newer
version didn't use it. This can be fixed by installing an empty directory
into /var/lib/maxscale.
