mcsadmin restart will do a status call. Before this would log status
output to a file which would be checked. If that file check failed a PID
check would be made.
We do not log the status to a file any more since it could have multiple
different outputs. The PID check could hit a race condition where it is
being checked before the process is up. This would mean there is no
module state change causing a hang.
This fix does the following:
1. Remove the file status check completely
2. Loop the PID check to give it time to come up
3. If the PID check fails drop to a DEGRADED state
This makes mcsadmin restart work correctly again.
MariaDB server is now managed using systemd instead of our own
mysql-Columnstore script. This means that MariaDB server can be stopped
/ started independently of ColumnStore
log_bin is missing from columnstore.cnf. This causes a search for the
master log file to fail and replication doesn't apply.
This patch adds a commented out log_bin which is enabled as needed.
It also fixes an error message.
Todd & Andrew ID'd the problem as being that the libjemalloc.so ->
(real lib) link doesn't always exist for whatever reason. I hacked our
run script to try the 3 possibilities mentioned in the ticket in this order
1) libjemalloc.so
2) libjemalloc.so.1
3) libjemalloc.so.2
Failing that, it will fall back to an empty LD_PRELOAD, so libc
would be used for the allocator.
Fixes the immediate problem. The lib_bin and server_id vars mentioned
in the ticket are untouched by this commit.
Rename packages to MariaDB-columnstore-engine, MariaDB-columnstore-libs
and MariaDB-columnstore-platform.
Also add the "columnstore-" prefix the the components so that MariaDB's
packaging system understands then and add a line to include them in
MariaDB's packaging.
In addition
* Fix S3 building for dist source build
* Fix Debian 10 dependency issue
* Fix git handling for dist builds
* Add support for MariaDB's RPM building
* Use MariaDB's PCRE and readline
* Removes a few dead files
* Fix Boost noncopyable includes
Linking will become an issue for the unified build and it is an issue
for jemalloc 5.x. Instead we will LD_PRELOAD on the forked ColumnStore
specific processes.
It is possible for ProcMon can be left behind during a node shutdown.
This patch makes sure it is killed and makes sure it is killed before a new
one starts.
The new "columnstore stop" command doesn't work well if the cluster is
already down. Instead we need to use the older method to stop
ProcMon/ProcMgr on the node before starting it.
Adds back some stuff that was remove distributed that didn't work
properly for non-distributed. Also use /var/lib/columnstore/local
for module file as OAM intended.
ColumnStore now uses standard bin/lib paths for pretty much everything.
Data path is now hard-coded to /var/lib/columnstore.
This patch also:
* Removes v1 decompression
* Removes a bunch of unneeded files
* Removes COLUMNSTORE_INSTALL_DIR / $INSTALLDIR
* Makes my.cnf.d work for all platforms (MCOL-3558)
* Changes configcpp to use recursive mutex (fixes possible config write deadlock)
* Fixes MCOL-3599 Fix regr functions, The library was installed in the wrong location
* Fixes a bunch of Ubuntu packaging issues
* Changes the binary names of several of the executables so as not to
clash with potential executables from other packages
This branch enforces the use of generic MariaDB server paths for their
binaries and data rather than custom paths.
/usr/local/mariadb/columnstore is now only for columnstore with this
patch.
It should be noted that this removes the auto-mounting of external
MariaDB UM data storage for AWS.
This is also a fix for MCOL-3510 after buildbot changes are made.
Also... MCOL-3552 Use columnstore.cnf to load plugins
The ColumnStore plugins now load using a columnstore.cnf instead of a
SQL sequence to be more in-line with MariaDB's methods.
This patch:
* Moves config files from /usr/local/mariadb/columnstore/etc to
ENGINE_SYSCONFDIR/columnstore (ENGINE_SYSCONFDIR is /etc by default)
* Sets a define called MCSSYSCONFDIR whic contains the
ENGINE_SYSCONFDIR compile time setting
* Modifies scripts and code to use the new paths
* Removes a whole bunch of files we don't use
This patch:
* Moves ColumnStore my.cnf to /etc/my.cnf.d/columnstore.cnf
* Removes unneeded entries from columnstore.cnf
* Removes some things that used my.cnf and are now dead
* Also removes utils/scenarios
* Modifies things that use extra defaults file to use the standard one
* Makes sure that C++11 standard is used for older CMake versions
With this patch we no longer need to set -DINSTALL_SYSCONF2DIR and
-DINSTALL_SYSCONFDIR when building MariaDB server.
