> Metalink: Fix crash when checking the digest of a file that wasn't cacheable
> ----------------------------------------------------------------------------
>
> Key: TS-2939
> URL: https://issues.apache.org/jira/browse/TS-2939
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Jack Bates
> Assignee: Jack Bates
> Fix For: sometime
>
>
> TSCacheRead() is reentrant particularly in case of a cache miss so its
> handler might execute sooner than expected particularly when the Metalink
> plugin is checking the digest of a file that wasn't cacheable. This
> TSCacheRead() handler will clean up an earlier TSVConnRead() buffer but
> CacheVC::openReadMain() will continue operating on the buffer and crash.
> Close the virtual connection to stop it from operating on the buffer.
