<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;">This looked to be a fairly straight forward patch (provided by the issue reporter, Filip Jenicek) - however, since the last time a memory leak was 'fixed' in app_voicemail it caused a memory corruption, I figured I'd post it up for review.
This patch fixes two memory leaks:
1. When find_user is called with NULL as its first parameter, the voicemail user returned is allocated on the heap. The inboxcount2 function uses find_user in such a fashion when counting new messages, and fails to free the resulting voicemail user object.
2. When populate_defaults is called on a voicemail user, it wipes whatever flags have been set on the object by copying over the global flags object. If the VM_ALLOCED flag was set on the voicemail user prior to doing so, that flag is removed. This leaks the voicemail user when free_user is later called.
This patch differs slightly from Filip's patch in that the populate_defaults function isn't changed to preserve the VM_ALLOCED flag, as that function affects a significant number of places in the code (and the comments for the function state that it copies over the global flags - so we probably should have expected that flags set prior to the function would be blown away). Instead, places that set the VM_ALLOCED flag do so now after calling populate_defaults.
This affected IMAP users and realtime users (and a unit test).</pre>
