Paul Smith 9ae02b7916 [SV 45728] Detect changes in .VARIABLES more accurately. ... For performance, we only recompute .VARIABLES when (a) it's expanded and (b) when its value will change from a previous expansion. To determine (b) we were checking the number of entries in the hash table which used to work until we started undefining entries: now if you undefine and redefine the same number of entries in between expanding .VARIABLES, it doesn't detect any change. Instead, keep an increasing change number. * variables.c: Add variable_changenum. (define_variable_in_set, merge_variable_sets): Increment variable_changenum if adding a new variable to the global set. (undefine_variable_in_set): Increment variable_changenum if undefining a variable from the global set. (lookup_special_var): Test variable_changenum not the hash table. * tests/scripts/variables/special: Test undefining variables.		2016-03-13 18:23:20 -04:00
