Analysis:
The value gets appended as string instead of unescaped json value
Fix:
Append the value of json in a temporary string and then store it in the
field instead of directly storing as string.
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
non-default collation_connection
Analysis:
Due to different collation, the string has nothing to chop off.
Fix:
Got rid of chop(), only append " ," only when we have more elements to
add to the result.
Analysis:
When we scan json to get to a beginning according to the path, we end up
scanning json even if we have exhausted it. When eventually returns error.
Fix:
Continue scanning json only if we have not exhausted it and return result
accordingly.
Analysis:
When scanning json and getting the exact path at each step, if a path
is reached, we end up adding the item in the result and immediately get the
next item which results in current path changing.
Fix:
Instead of immediately returning the item, count the occurences of the path
in argument and append in the result as needed.
(returns NULL) and for Date/DateTime returns "INTEGER"
Analysis:
When the first character of json is scanned it is number. Based on that
integer is returned.
Fix:
Scan rest of the json before returning the final result to ensure json is
valid in the first place in order to have a valid type.
Some fixes related to commit f838b2d799 and
Rows_log_event::do_apply_event() and Update_rows_log_event::do_exec_row()
for system-versioned tables were provided by Nikita Malyavin.
This was required by test versioning.rpl,trx_id,row.
Modify the NS_ZERO state in the JSON number parser to allow
exponential notation with a zero coefficient (e.g. 0E-4).
The NS_ZERO state transition on 'E' was updated to move to the
NS_EX state rather than returning a syntax error. Similar change
was made for the NS_ZE1 (negative zero) starter state.
This allows accepted number grammar to include cases like:
- 0E4
- -0E-10
which were previously disallowed. Numeric parsing remains
the same for all other states.
Test cases are added to func_json.test to validate parsing for
various exponential numbers starting with zero coefficients.
