Chuck Rolke commented on DISPATCH-1407:
---------------------------------------
Analysis to date:
* Valgrind shows only python-related mallocs; this is inconclusive. Valgrind
shows no actionable C-language malloc leaks.
* The same problem is present in 1.7.0, 1.6.0, 1.5.0, and 1.4.x
* Policy code was modified not to include setting pn_condition to signal the
error - still has memory growth
* Container code was modified to call pn_condition_clear for local and remote
conditions when link is detached - no change
* Tried making a policy.c static python module load and not loading only when
needed - no change
> Memory leak on link policy denial

> Key: DISPATCH-1407
> URL: https://issues.apache.org/jira/browse/DISPATCH-1407
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Policy Engine
> Affects Versions: 1.8.0
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
> Priority: Major
> Attachments: A.conf, default.json
>
>
> A router with a simple policy that denies most addresses starts and uses 10M
> bytes of memory. A test client loops 25k times opening a link to a denied
> address over a single connection and session. Now the router uses 276 Mbytes.
> An example policy is
> ```
> [
> ["vhost", {
> "hostname": "$default",
> "allowUnknownUser": true,
> "groups" : {
> "$default": {
> "remoteHosts": "*",
> "allowDynamicSource": true,
> "allowAnonymousSender": true,
> "sources": "$management, examples, q1",
> "targets": "$management, examples, q1"
> }
> }
> }]
> ]
> ```
