This patch does exactly this, it implements support for JSON in DDL.
Right now we use server's check for JSON validity on INSERT. We do not implement
JSON validity check during updates, it is postponed for later work.
This patch changes logic from counting all nodes to counting only
read-write nodes when messaging about DML operations.
feat(MCOL-6082): Multiple readers of dbroots using OamCache logic
This patch introduces centralized logic of selecting what dbroot is
accessible in PrimProc on what node. The logic is in OamCache for time
being and can be moved later.
Fix build
* 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* Fix ISO C++17 does not allow 'register' storage class specifier for outdated bison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
* TEXT and BLOB now have separate identifiers internally
* TEXT columns are identified as such in system catalog
* cpimport only requires hex input for BLOB, not TEXT
* DML writes for multi-block dictionary (blob) now works
* PrimProc fixed so that the first block in multi-block is read
correctly
* Performance optimisation (removed string copy into stack) for new
dictionary entries
Date limit of year 1400 was used due to Boost's limits.
This patch strips out the use of Boost for date handling and sets the
lower limit to year 1000.
