Option to detect concurrent accesses to pools
db028c4 
Enabled by new configure option --enable-pool-concurrency-check.

Compared to pool-owner-debugging, this only detects cases where there is actual
contention between accesses. The advantage is that runtime costs should be
relatively low.

The diagnostic messages could still use some improvement.

Add new --enable-allocator-guard-pages configure option which works like

to find/protect against certain buffer overflow/overread bugs.

Hello @jeking3
I not have windows PC and cannot build and test code for Windows platform. Could you create PR to my repo? I will merge your PR into this.

I would recommend committing this because technically it isn't wrong - it returns "not implemented", and someone will do then win32 side when they need it. I would implement it such that the documented API would be used, and then if Windows is an earlier version than that API supports, to use the trick found in https://www.codeproject.com/articles/8549/name-your-threads-in-the-vc-debugger-thread-list.

If pull requests here leveraged Travis CI and Appveyor you would be able to make those changes and see the tests pass... it's too bad the project doesn't leverage the free CI tools that exist for open source projects.

Sure, although I should ask why folks more closely tied to the project are not reviewing the pull requests? I am a PMC member on Thrift, and I maintain some Boost libraries... I don't look at apr that often.

@jeking3: activity mostly happens on the dev@apr.apache.org mailing list and bugzilla.
PRs are looked at from time to time, by individuals...

@sergey-safarov: a new function mostly ENOTIMPL (but on some pthread implementations, as _np suffix suggests) is not very attractive for APR (P stands for Portable). Any chance to at least handle Windows per MSDN link? (I can't compile nor test myself unfortunately).
Maybe for your use case apr_os_thread_get() could help to do native calls on the native thread descriptor.

Merge r1883750 from trunk:
2b85c17 
apr_pools: lock parent pool in pool_destroy_debug().

By using apr_pool_clear_debug() instead of pool_clear_debug() in
pool_destroy_debug() we gain the locking provided by the former and thus
protection from concurrent access from apr_pool_walk_tree(), which is
undefined behaviour.

While pool_destroy_debug()=>apr_pool_clear_debug()=>pool_clear_debug() calls
pool_destroy_debug() for all the children pools, this does not cause a deadlock
because apr_pool_clear_debug() locks the parent pool only (not the pool itself)
and thus pool_destroy_debug(pool->child) locks the current pool with no issue.

This fixes use-after-free like the below in httpd (with -D APR_POOL_DEBUG):

apr_pools: lock parent pool in pool_destroy_debug().
94d2e04 
By using apr_pool_clear_debug() instead of pool_clear_debug() in
pool_destroy_debug() we gain the locking provided by the former and thus
protection from concurrent access from apr_pool_walk_tree(), which is
undefined behaviour.

While pool_destroy_debug()=>apr_pool_clear_debug()=>pool_clear_debug() calls
pool_destroy_debug() for all the children pools, this does not cause a deadlock
because apr_pool_clear_debug() locks the parent pool only (not the pool itself)
and thus pool_destroy_debug(pool->child) locks the current pool with no issue.

This fixes use-after-free like the below in httpd (with -D APR_POOL_DEBUG):

apr_crypto: fix potential memory leaks of cprng_stream_ctx_t.
398fc32 
This can happen in cprng_stream_ctx_make() on error paths, or at thread exit
with APR_CRYPTO_PRNG_PER_THREAD like the below.

Direct leak of 64 byte(s) in 8 object(s) allocated from:
