* fix C API includes
ColumnStore used to include server's mysql.h
but link all tools with libmariadb.so
There's no guarantee that this would work, even with workarounds
it had in dbcon/mysql/sm.cpp
Fix:
* tools (linked with libmariadb.so) *must* include libmariadb's mysql.h
* as a hack prevent service_thd_timezone.h from being loaded into tools,
as it conflicts with libmariadb's mysql.h
* server plugin *must* include server's mysql.h
* also don't link every tool with libmariadb.so, link the helper library
(liblibmysqlclient.so) that actually needs it, tools use this
helper library, not libmariadb.so directly
* do *not* link ha_columnstore.so with libmariadb.so
this means some libraries have to be compiled twice -
for tools with libmariadb.so and for plugin, without.
* use system boost, if possible
boost 1.71.0 is what ubuntu focal has, so let's start with that version.
boost 1.77.0 is the first that supports c++20
* add dependency for generated header files errorids.h messageids.h
see 3edd51610
* bump the version
* MCOL-5322 This patch replaces boost::mutex with std::mutex b/c IMHO std::unique_lock::lock is
less troublesome comparing with the boost alternative
* MCOL-5310 This patch replaces move-assignment with copy-assignment to avoid memory corruption (#2661)
* Bump VERSION to 22.08.7-1
* MCOL-5306 Re-read the config (Columnstore.xml) file if it was updated.
The existing implementation of Config::makeConfig() factory method
was returning a possibly stale config to the caller, without checking
if the config file was updated since the last read. This bug triggered
a scenario as described in MCOL-5306 where after a failover in an MCS
cluster, the controllernode coordinates changed in the config file
after failover and the existing mariadbd process was still using the
old controllernode coordinates. This lead to failed network connection
between mariadbd and the new controllernode.
The change in this fix, however, is more generic and not just limited
to this above scenario.
* MCOL-5264 This patch replaces boost mutex locks with std analogs
boost::uniqie_lock dtor calls a fancy unlock logic that throws twice.
First if the mutex is 0 and second lock doesn't own the mutex.
The first condition failure causes unhandled exception for one of the clients
in DEC::writeToClient(). I was unable to find out why Linux can have a 0
mutex and replaced boost::mutex with std::mutex b/c stdlibc++ should
be more stable comparing with boost.
* MCOL-5311 Add timezone to jobList in subquerytransformer
TimeZone was uninitialized in this scenario and led to undefined behavior.
* patch_out_of_band
Some changes made to 10.6-enterprise make a build using the out-of-band method of compiling columnstore not work. Out-of band means the source for the engine is not in the storage subdir of server, but rather in a stand alone directory. This is used by developers for easier develop work. In the case of out-of-band, INSTALL_LAYOUT is false in CMakeLists.txt
* MCOL-5346 This patch forces TreeNode::getIntValue to use conversion for dict-based CHAR/VARCHAR and TEXT columns (#2657)

* MCOL-5263 Add support to ROLLBACK when PP were restarted.
DMLProc starts ROLLBACK when SELECT part of UPDATE fails b/c EM facility in PP were restarted.
Unfortunately this ROLLBACK stuck if EM/PP are not yet available.
DMLProc must have a t/o with re-try doing ROLLBACK.
* MCOL-3561 This patch updates Connector code after MDEV-29988
* This commit applies the code style format

* Fix clang warnings
* Remove vim tab guides
* initialize variables
* 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length
* Fix ISO C++17 does not allow 'register' storage class specifier for outdated bison
* chars are unsigned on ARM, having if (ival < 0) always false
* chars are unsigned by default on ARM and comparison with -1 if always true
* Adds CompressInterfaceLZ4 which uses LZ4 API for compress/uncompress.
* Adds CMake machinery to search LZ4 on running host.
* All methods which use static data and do not modify any internal data - become `static`,
so we can use them without creation of the specific object. This is possible, because
the header specification has not been modified. We still use 2 sections in header, first
one with file meta data, the second one with pointers for compressed chunks.
* Methods `compress`, `uncompress`, `maxCompressedSize`, `getUncompressedSize` - become
pure virtual, so we can override them for the other compression algos.
* Adds method `getChunkMagicNumber`, so we can verify chunk magic number
for each compression algo.
* Renames "s/IDBCompressInterface/CompressInterface/g" according to requirement.
Fixes:
* Irrelevant where conditions
* Irrelevant const
* A potential infinite loop in treenode
* Bad implicit case fallthroughs
* Explicit markings for required case fallthroughs
* Unused variables
* Unused function
Also disabled some warnings for now which we should fix later.
This adds options which are user enabled to debug the LRU cache inside
ColumnStore. Specifically cache flushing.
It adds the following:
* PrimProc flush information when SIGUSR2 mode is enabled
* cpimport dictionary flush information when -d2 is used
* WriteEngineServer DML flush information to STDERR
Remove generated Makefiles
Update Makefile.am to specify RPATH as a subdirectory of --prefix
Remove configure artifacts such as config.log, config.h, etc
Remove unneeded backup files (files ending in tilde ~)
