* 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.
1. Extend the calpontsys.syscolumn system catalog table
with a new column, 'charsetnum'.
'charsetnum' field is set to the 'number' member of the
'charset_info_st' struct defined in the server in m_ctype.h.
For CHAR/VARCHAR/TEXT column types, 'charset_info_st' is
initialized to the charset/collation of the column, which
is set at the column-level or at the table-level in the DDL.
For BLOB/VARBINARY binary column types, 'charset_info_st' is
initialized to my_charset_bin (charsetnum=63).
For all other column types, charsetnum is set to 0.
2. Add support for the newly added 'charsetnum' column in the
automatic system catalog upgrade logic in dbbuilder.
For existing table definitions, charsetnum for the column is
defaulted to 0.
3. Add MTR test case that creates a few table definitions with
a range of charset/collation combinations and queries the
calpontsys.syscolumn system catalog table with the charsetnum
field for the columns in the table DDLs.
We have added a new function, SystemCatalog::upgrade(), which will
create a new column in the database and fill it with default values.
It uses a reference column to fill the column, which is passed as a
std::unordered_map<key, value> value to SystemCatalog::upgrade()
function, where key is the target column which needs to be created.
In addition, we pass additional std::unordered_map's to
SystemCatalog::upgrade() containing information such as the datatypes
and colwidths of the target and reference columns, as well as the
default value which will be used to fill the target column.
* 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* Fix ISO C++17 does not allow 'register' storage class specifier for outdated bison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
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 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
