* Don't waste memory when creating or allocating from small, long-livedsf2014-05-141-2/+8
| | | | | | | | | | | | | | | | | | | | | | | APR pools after clearing or destroying pools that allocated larger nodes. When allocating nodes from the bucket allocator (<= 80k or 20 pages), we would eagerly reuse *any* free node that is at least the minimum size. Depending on the pool usage scheme, that extra memory would never be used. This patch limits the node to approximate twice the minimum. * memory/unix/apr_pools.c (allocator_alloc): When searching the buckets for free nodes, limit the range to twice the starting index.

* Add valgrind supportsf2013-01-261-19/+126
| | | | | | | | | | | | | | | | | Teach valgrind about apr pools, allocators, and bucket allocators if --with-valgrind is passed to configure. This has less impact on program behavior and performance than compiling with complete pool-debugging. Even with valgrind support compiled in, the performance impact if not running under valgrind should be minimal. It may make sense to use pool-debugging together with valgrind support because pool-debugging does not help with allocators and bucket allocators. git-svn-id: http://svn.apache.org/repos/asf/apr/apr/trunk@1438957 13f79535-47bb-0310-9956-ffa450edef68

This greatly reduces memory fragmentation with malloc implementations (e.g. glibc) that don't handle allocationss of a page-size-multiples in an efficient way. It also makes apr_allocator_max_free_set() actually have some effect on such platforms. The handling of page sizes other than 4k seems like a lot of trouble for a very small number of platforms, but there does not seem to be a reasonable way to check this at compile time. git-svn-id: http://svn.apache.org/repos/asf/apr/apr/trunk@1072165 13f79535-47bb-0310-9956-ffa450edef68
