Description
There're few issues around using +d,-d with the intent to increment and restore the former
state of DEBUG_DBUG variable.
In particular when +d, keyword adds the very first keyword and by thus activates the state
for the specified keyword the following -d,keyword does remove the keyword but leaves the active state for everything, including pollution of the server error log.
There a patch

BUG#11765644: DEBUG 'D' LIST SHOULD STAY EMPTY AFTER SET
|
DEBUG="+D,<SYMBOL>"
|
PROBLEM AND FIX:
|
When the debug 'd' flag has been set to empty, then all
|
DBUG_ macros are enabled. But if one then sets debug="
|
+d,foo" then only foo, all others are turned off. The
|
expected/intended behaviour should be to add debug for
|
'symbol' in addition to whatever was enabled before.
|
The fix adds keyword to the stack of active keyword list
|
if debug was not enabled for all symbols. Also turn debug
|
off if the last keyword is removed from the stack of
|
keywords. NOTE: This shall require a change in the docs
|
to reflect the changed behaviour in this bug
|
that addresses that and few more use cases.
