[jira] Updated: (QPID-2523) When reloading a large acl file while
acl lookup is in progress, the broker core dumps
[ https://issues.apache.org/jira/browse/QPID-2523?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rajith Attapattu updated QPID-2523:
-----------------------------------
Attachment: QPID-2523-reproducer.tar.gz
This issue is likely to happen with a sufficiently large acl file. (~ 1000+ entries)
With a smaller file (~100 entries) it takes a few iterations to happen.

> Key: QPID-2523

> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: M4, 0.5, 0.6
> Reporter: Rajith Attapattu
> Assignee: Rajith Attapattu
> Fix For: 0.7

> Description of problem:
> When reloading a large acl file , the broker core dumps.
> This surfaced while running the attached reproducer.
> How reproducible:
> Always - reproducer attached.
> Steps to Reproduce:
> 1. Start the broker with the acl module and and --acl-file /tmp/policy.acl
> 2. The initial acl file should contain only "acl allow all all"
> 3. run the message_sender.py (This program will keep on publishing to
> amq.direct)
> 4. run acl_reloader.py with --mode allow | deny a few times
> Actual results:
> The broker core dumps.
> Expected results:
> The broker should continue to work after reloading the acl file properly.
> Additional info:
> Following is the backtrace from the code dump.
