Since you're in the vicinity, you could replace "imappasswd" with "imapfolder" in the string below.
I'd do it, but I left my commit access at home ;)
if (strcasecmp(vmu->imapfolder, "INBOX")) {
ast_test_status_update(test, "Parse failure for imappasswd option\n");
res = 1;
}
Further, I see in:
static int __messagecount(const char *context, const char *mailbox, const char *folder)
another find_user() but no free_user() of vmu.
And in leave_voicemail() only /some/ returns are preceded by a free_user(). And
more of the same in vm_authenticate().. and a pretty blatant one in
both vm_box_exists() and acf_mailbox_exists() and the list goes on.
I'll just ship-it and leave the rest for later ;)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Test problem fixed.
You actually don't need to call free_user on a voicemail user obtained from find_user unless the first parameter passed to find_user is NULL. On the other hand, free_user should be safe to call in all cases, as a non-malloc'd voicemail user is simply passed over in free_user, and it would make the semantics of calling find_user consistent throughout app_voicemail. I didn't want to expand the patch any more than I needed to (dramatic changes in app_voicemail have a tendency to haunt the programmer)

<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>
