Devel::Leak has two functions NoteSV and CheckSV.
|
|
|
|
NoteSV walks the perl internal table of allocated SVs (scalar values) - (which
|
|
actually contains arrays and hashes too), and records their addresses in a
|
|
table. It returns a count of these "things", and stores a pointer to the
|
|
table (which is obtained from the heap using malloc()) in its argument.
|
|
|
|
Note that you need a perl built with -DDEBUGGING for
|
|
sv_dump() to print anything, but counts are valid in any perl.
|
|
|
|
If new "things" have been created, CheckSV may (also) report additional
|
|
"things" which are allocated by the sv_dump() code.
