<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks for finishing it.
- I think you addressed all comments.
- The changes you made look good. (I didn't check for flaws in the original/unchanged parts.)
- Tested with mysql and postgres and it still fixes the crash.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'd prefer to replace this with:
do_reconnect = (!obj->up && !obj->tx);
then place a
int do_reconnect = 1;
at the top before if(!wrlock).
And wrap the highlighted stuff here in a if (do_reconnect) {}.
That way we won't have the duplicate comment+disconnect+connect code.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I started by confirming that the segfault could be easily reproduced with wdoekes' setup mentioned in the issue report.
After finishing the changes to the patch, I confirmed that following the same steps no longer produced the segfault, undid the patch to double check that I was doing it right, and then decided it was safe to post this review.</pre>
