Subject: [PATCH] Data::Dumper - avoid leak on croak
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
v5.21.3-742-g19be3be696 added a facility to Dumper.xs to croak if the
|
||||
recursion level became too deep (1000 by default).
|
||||
|
||||
The trouble with this is that various parts of DD_dump() allocate
|
||||
temporary SVs and buffers, which will leak if DD_dump() unceremoniously
|
||||
just croaks().
|
||||
|
||||
This currently manifests as dist/Data-Dumper/t/recurse.t failing under
|
||||
Address Sanitiser.
|
||||
|
||||
This commit makes the depth checking code just set a sticky 'too deep'
|
||||
boolean flag, and
|
||||
a) on entry, DD_dump() just returns immediately if the flag is set;
|
||||
b) the flag is checked by the top-level called of DD_dump() and croaks
|
||||
if set.
|
||||
|
||||
So the net effect is to defer croaking until the dump is complete,
|
||||
and avoid any further recursion once the flag is set.
|
||||
|
||||
This is a bit of a quick fix. More long-term solutions would be to
|
||||
convert DD_dump() to be iterative rather than recursive, and/or make
|
||||
sure all temporary SVs and buffers are suitably anchored somewhere so
|
||||
that they get cleaned up on croak.
