[jira] [Commented] (TS-877) Segfault caused by

Leif Hedstrom commented on TS-877:
----------------------------------
And, we should probably figure out why m_alt is NULL still, and perhaps invalidate a cache object where that would occur? I mean, even though it's most likely a cache corruption, it'd be nice to be able to deal with it slightly better than a segfault.

----------------------------------
Another thought could be that the cache got corrupted. Asking if the OP can try to clear the cache.

Leif Hedstrom commented on TS-877:
----------------------------------
Looking at how this API is used, I'm wondering (but, far, far from certain) if there's a missing test at the beginning, e.g.
{code}

Now, the real question is, why is m_alt == NULL to begin with?

[jira] [Commented] (TS-877) Segfault caused by
HTTPInfo::object_key_get
Posted by "Alan M. Carroll (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066020#comment-13066020 ]
Alan M. Carroll commented on TS-877:
------------------------------------
I don't think this has anything to do with the cache on disk. My reading of the code is that this involves reading from live cache fills. SelectFromAlternates is picking the particular writer (cache fill) for a reader and it's picked on that's invalid (m_alt == NULL). You can see that an effort is made to prevent the selection vector from containing an invalid entry but it's not clear to me from looking at code (primarily CacheVC::openReadChooseWriter) how entries that "time out" are purged. Note that current writers are scanned for validity and removed, but the vector itself is not cleared. Moreover, the vector is a class member so it can contain cruft from previous operations on the class. One thing to get more information would be to put a check at the start of that method that loops over the vector and checks for invalid entries and see if that goes off.

[jira] [Updated] (TS-877) Segfault caused by

Leif Hedstrom updated TS-877:
-----------------------------
Lets move this out to 3.1.1 or 3.1.2, we need better understanding on how this gets corrupted in the first place. And perhaps change the underlying code instead of trying to deal with the symptoms (as we discussed earlier).
