[add] cluster api client class
[fix] cli cluster_app using cluster api client
[add] ClusterAction Enum
[add] toggle_cluster_state function to reduce code duplication
If you manage to shut down PrimProc just before plugin is trying to send
Calpont Select Execution Plan to PrimProc, you now get a nice error
message about PrimProc being down instead of endless logs of failed
reconnection attempts.
[add] now all 'cluster' subcommand commands working without using 'cluster' subcommand itself
[fix] 'cluster' command hidding its help message
[add] explicit names for commands
[add] help-all command to list all nested help messages in man page view
[add] rich colored tabled help
[add] table panels for cluster commands
[upd] typer dependency version and some extra indirect dependencies
[add] README.md for mcs cli tool with all command reference
[add] mcs.1 man page
[add] README_DEV.md for mcs cli tool
[fix] cmapi/CMakeLists.txt to install mcs.1 man page
JSON_OBJECT() (and probably some other JSON functions) now properly
handle empty strings in their arguments - JSON_OBJECT used to return
NULL, now it returns empty string.
The commit introduces a new CMake configuration option, WITH_THRIFT,
which accepts "auto", "system", or "bundled". In "auto" mode (the
default), the build system attempts to use the system-installed Thrift
library and falls back to the bundled version if the system library is
not available. Setting WITH_THRIFT to "system" enforces the use of the
system Thrift, causing the configuration to fail if it isn't found,
while "bundled" forces the use of the bundled version.
The change mainly useful for downstream maintainers as it gives them
flexibility over dependency management.
Downstream-issue: https://bugs.gentoo.org/949680
Sometimes server assigns DOUBLE type for arithmetic operations over
DECIMAL arguments. In this rare case width of result was incorrectly
adjusted and it triggered an assertion.
Now width of result gets adjusted only if result type is also DECIMAL.
Taken from FreeBSD ports, this uses the FreeBSD
APIs rather than the Linux specific prctl to change
and retreive the thread names.

* feat(BRM,tools): couple utilities to watch/operate shared memory locks and extent map
* feat(BRM,tools): merged two utilities and added some extra dbbuilder output in case of upgrade
* fix(dbbuilder): extra output to log upgrade detection.
This patch introduces an internal aggregate operator SELECT_SOME that
is automatically added to columns that are not in GROUP BY. It
"computes" some plausible value of the column (actually, last one
passed).
Along the way it fixes incorrect handling of HAVING being transferred
into WHERE, window function handling and a bit of other inconsistencies.
Fixes in UBSAN related commit introduced more server-compatible
behavior that differ fom our old behavior. Thus, old tests broke and
their results had to be changed. This is what this patch does.
There were numerous memory leaks in plugin's code and associated code.
During typical run of MTR tests it leaked around 65 megabytes of
objects. As a result they may severely affect long-lived connections.
This patch fixes (almost) all leaks found in the plugin. The exceptions
are two leaks associated with SHOW CREATE TABLE columnstore_table and
getting information of columns of columnstore-handled table. These
should be fixed on the server side and work is on the way.
* feat(joblist,runtime): this is the first part of the execution model that produces a workload that can be predicted for a given query.
- forces to UM join converter to use a value from a configuration
- replaces a constant used to control a number of outstanding requests with a value depends on column width
- modifies related Columnstore.xml values
The most important fix here is the fix of possible buffer overrun in
DATEFORMAT() function. A "%W" format, repeated enough times, would
overflow the 256-bytes buffer for result. Now we use ostringstream to
construct result and we are safe.
Changes in date/time projection functions made me fix difference between
us and server behavior. The new, better behavior is reflected in changes
in tests' results.
Also, there was incorrect logic in TRUNCATE() and ROUND() functions in
computing the decimal "shift."
* Minor fix in timeout for /notfound "endpoint" call.
- [fix] timeout to urlopen /notfound "endpoint" in mcs-savebrm and mcs-loadbrm
* chore(CMAPI): reduced a second Time Out asking MDB for a async replication status. The latency must be small b/c MDB Server to be requested is local.

* fix(rowgroup): RGData now uses uint64_t counter for the fixed sizes columns data buf.
The buffer can utilize > 4GB RAM that is necessary for PM side join.
RGData ctor uses uint32_t allocating data buffer.
This fact causes implicit heap overflow.
* feat(bytestream,serdes): BS buffer size type is uint64_t
This necessary to handle 64bit RGData, that comes as
a separate patch. The pair of patches would allow to
have PM joins when SmallSide size > 4GB.
* feat(bytestream,serdes): Distribute BS buf size data type change to avoid implicit data type narrowing
* feat(rowgroup): this returns bits lost during cherry-pick. The bits lost caused the first RGData::serialize to crash a process
