TS-4608: Fix memory leak in ProxyAllocator.cc. (#774)
This removes the pre-processor flag TS_USE_FREELIST which is not defined since
commit e56d1f9eb6f55b0257d1fb758b773dea468159ee to make freelists a runtime
option.
(cherry picked from commit e707c3ec02d71ae079db9282c825d0449f62a88c)
> Memory leak in ProxyAllocator.cc
> --------------------------------
>
> Key: TS-4608
> URL: https://issues.apache.org/jira/browse/TS-4608
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Jay Ramamurthi
> Priority: Blocker
> Fix For: 6.2.0, 7.0.0
>
>
> The change to make freelists a runtime option
> (https://github.com/apache/trafficserver/commit/e56d1f9eb6f55b0257d1fb758b773dea468159ee)
> seems to have missed this file.
> With the preprocessor symbol TS_USE_FREELIST now gone (earlier used to be 1),
> the overload of thread_alloc defined in this file always uses Proxy Allocator
> (the second argument to the method) but free routines are from the freelist.
> This overload of thread_alloc is used by HdrHeap, that is widely used in
> transaction processing, causing leaks.
> Steps to reproduce:
> Traffic server with a single remap configuration, and ab workload should show
> memory growth.
> Version seen in: Traffic Server built from branches master, 6.1.x, 6.2.x.
> Platform: Linux 64-bit (RHEL 6.6), g++ 4.4.7
