<div dir="ltr"><div>hi,<br></div> I wanted to remove 'get_new_dict()', 'dict_destroy()' usage through out the code base to prevent people from using it wrong. Regression for that patch <a href="http://review.gluster.org/13183">http://review.gluster.org/13183</a> kept failing and I found that the 'xl->options' dictionary is created using get_new_dict() i.e. it doesn't have any refs. And in xlator_members_free() we try to destroy it using dict_unref() i.e. ref count becomes '-1' and the dictionary doesn't get destroyed. so every reconfigure is leaking dictionaries. So all the options which use string options actually point to the values in these dictionaries. Initially I thought we can have latest reconfigured options dictionary also stored in new member 'xl->reconfigured_options' but the problem is reconfigure can partially succeed leading to dilemma about which options succeeded/failed and which dictionary to keep around. Failing in reconfigure doesn't stop the brick. At the moment the only way out I see is to perform [de]allocation of the string, bool(we can prevent for bool) options, may be there are more, I need to check. But this becomes one more big patch('fini' should GF_FREE all these options), so wondering if anyone has any other thoughts on fixing this properly without a lot of code changes.<br clear="all"><div><div><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Pranith<br></div></div>
