* apr_thread: Follow up to r1897207: apr_thread_current_create() compilation.Yann Ylavic2022-02-081-0/+1

| | | | | | | | | | | | | | | thread_local variables are not (always?) reset on fork(), so APR (and the user) needs a way to set the current_thread to NULL.

* apr_thread: Use compiler's TLS to track the current apr_thread_t's pointer.Yann Ylavic2022-01-191-23/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All modern compilers provide a Thread Local Storage keyword that allows to store per-thread data efficiently (C++11 's thread_local, C11's _Thread_local, gcc/clang's __thread or MSVC's __declspec(thread)). Use that to have an apr_thread_t pointer associated with each thread created by apr_thread_create() or any native thread (like the process' initial thread) that registered itself with the new apr_thread_current_create() function. This mechanism allows to implement apr_thread_current() quite efficiently, if available, otherwise the function returns NULL. If available APR_HAS_THREAD_LOCAL is #define'd to 1 and the APR_THREAD_LOCAL macro is the keyword usable to register TLS variables natively. Both APR_HAS_THREAD_LOCAL and APR_THREAD_LOCAL are #undef'ined if the compiler does not provide the mechanism. This allows to test for the functionality at compile time. When APR_HAS_THREAD_LOCAL, the user can load his/her own TLS data with: apr_thread_data_get(&my_data, my_key, apr_thread_current()); and store them with: apr_thread_data_set(my_data, my_key, my_data_cleanup, apr_thread_current()); which can be nice to avoid the proliferation of native TLS keys.

* apr_thread: Allocate the apr_thread_t struct on the thread's pool.Yann Ylavic2022-01-191-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | apr_thread_create() was allocating the created apr_thread_t on the given pool, which caused e.g. short-living threads to leak memory on that pool without a way to clear it (while some threads are still running). Change this by allocating the apr_thread_t on the thread's pool itself, which is safe in the implementations of all archs because none uses the apr_thread_t after the thread exits, and it's safe for the users provided they don't use the apr_thread_t for detached threads or for attached threads after the call to apr_thread_join(). These are hardly new requirements though. apr_thread: Follow up to r1897197: Safer apr_thread_join(). Make sure apr_thread_join() behaves correctly w.r.t. the returned value and pool destroy for all archs. Merge r1897197, r1897198 from trunk.

* apr_thread: Follow up to r1884078: Unmanaged pools for attached threads too.Yann Ylavic2022-01-191-52/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | r1884078 fixed lifetime issues with detached threads by using unmanaged pool destroyed by the thread itself on exit, with no binding to the parent pool. This commit makes use of unmanaged pools for attached threads too, they needed their own allocator anyway due to apr_thread_detach() being callable anytime later. apr__pool_unmanage() was a hack to detach a subpool from its parent, but if a subpool needs its own allocator for this to work correctly there is no point in creating a subpool for threads (no memory reuse on destroy for short living threads for instance). Since an attached thread has its own lifetime now, apr_thread_join() must be called to free its resources/pool, though it's no different than before when destroying the parent pool was UB if the thread was still running (i.e. not joined yet). Let's acknoledge that threads want no binding with the pool passed to them at creation time, besides the abort_fn which they can steal :) Merge r1897179 from trunk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OS/2: Clean up a thread's pool when it terminates. <not backported in 1.7.x> Add apr_pool_owner_set function to allow use of pool debugging with threads Actually this function has been mentioned in the docs for over 10 years but has never been implemented. </not backported in 1.7.x> Also consistently destroy the thread's pool when it exits normally, not only on apr_thread_exit(). This was already done on OS2. Other platforms than unix are untested. apr_thread: destroy the thread's pool at _join() time, unless _detach()ed. Destroying a joinable thread pool from apr_thread_exit() or when the thread function returns, i.e. from inside the thread itself, is racy or deadlocky with APR_POOL_DEBUG, with the parent pool being destroyed. This commit adds a ->detached flag in each arch's apr_thread_t struct to track whether a thread is detached (either at _create() or _detach() time). If detached, the pool is destroyed when the thread exits, otherwise when the thread is joined with apr_thread_join(). apr_thread: use unmanaged pools for detached threads. A detached thread is by definition out of control, unjoinable, unmanaged, and it can terminate/exit after its parent pool is detroyed. To avoid use-after-free in this case, let's use an unmanaged pool for detached threads, either by creating an unmanaged pool from the start if the thread is created detached, or by "unmanaging" the pool if the thread is detached later with apr_thread_detach(). To "umanage" the pool, provide a new internal helper, apr__pool_unmanage() which takes care of removing the pool from its parent's list.

| | | | | | | | | | | | | | | | | | | | | These may need massaging and do need review by their respective communities. Note that someone from the OS2 community needs to ping me with resolving the missing apr_arch_inherit.h mess; this should be very easy to translate into DosSetFHState(handle, OPEN_FLAGS_NOINHERIT); bits, but to more thoroughly resolve the issue, we should take it a step further and consider the NT implementation which toggles inheritance on only for handles as they hit proc_create, so that you don't have cross-process handle leakage into the wrong processes. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@584928 13f79535-47bb-0310-9956-ffa450edef68
