* Re-order the fields of 'struct apr_finfo_t' to avoid a hole and some padding.jailletc362023-02-191-2/+2

* apr_socket_sendv: WIN32: Follow up to r1902312: Avoid short writes.ylavic2022-10-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | We possibly (edge cases) can't send an entire iovec array in a single WSASend() call because structs WSABUF and iovec are ABI incompatible. To avoid breaking users that rely on full-write by apr_socket_sendv(), which supposedly is guaranteed by WSASend(), repeat the call until the given iovec array is exhausted. There is no way to provide both full-write and atomicity guarantees for apr_socket_sendv() on Windows, so we choose the former.. * include/apr_network_io.h: Document apr_socket_sendv() full-write/atomicity (non-)guarantees above the system ones. * network_io/win32/sendrecv.c(apr_socket_sendv): Change to a loop on WSASend() when needed, taking care of its API limits w.r.t. the given struct iovec.

* apr_thread: Provide apr_threadattr_max_free_set().ylavic2022-07-146-0/+14
| | | | | | | | | | | | | | | When creating a thread, this allows to specify the "max_free" of its pool allocator (i.e. apr_allocator_max_free_set), so that one can create thread local subpools and have their memory usage regulated on cleanup/destroy. One could achieve that already with: apr_allocator_max_free_set(apr_thread_pool_get(thread), max_free); in the thread startup function, but it's more convenient, simpler and race free to handle that in the thread attribute itself at creation time. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1902715 13f79535-47bb-0310-9956-ffa450edef68

* apr_thread: Use compiler's TLS to track the current apr_thread_t's pointer.ylavic2022-01-191-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1897207 13f79535-47bb-0310-9956-ffa450edef68

* apr_ring: Don't break strict-aliasing rules in APR_RING_SPLICE_{HEAD,TAIL}().ylavic2021-12-301-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC-11 complains (see [1]) about apr_brigade_split_ex() seemingly issuing an out of bounds access, the cause being that APR_RING_SPLICE_{HEAD,TAIL}() is dereferencing an APR_RING_SENTINEL() and the cast there in not very aliasing friendly (see [2] for a great explanation by Martin Sebor). The APR (and user code) should never dereference APR_RING_SENTINEL(), it's fine as a pointer only (i.e. for comparing pointers). So this commit modifies the APR_RING_SPLICE_{HEAD,TAIL}() and APR_RING_{CONCAT,PREPEND}() macros to use the passed in APR_RING_HEAD's prev/next pointers directly instead of passing the APR_RING_SENTINEL() to APR_RING_SPLICE_{BEFORE,AFTER}(). Semantically, this also clarifies that APR_RING_{SPLICE,INSERT}_{BEFORE,AFTER}() should be called for an APR_RING_ENTRY while APR_RING_SPLICE_{HEAD,TAIL}() and APR_RING_{CONCAT,PREPEND}() are to be called with an APR_RING_HEAD.

So below I allowed myself to edit the original comment to replace "_direntry" by "apr_bucket" and "anchor" by "list" (the apr_bucket_brigade's member used as the head of the ring) to make the link with the above commit message) " The message is a bit cryptic but it says that the code accesses an object (list) of some anonymous type as it was struct apr_bucket. That's invalid because objects can only be accessed by lvalues of compatible types (or char). The APR_RING_ENTRY macro is defined like so: #define APR_RING_ENTRY(elem) \ struct { \ struct elem * volatile next; \ struct elem * volatile prev; \ } so given the definition: APR_RING_ENTRY(apr_bucket) list; list can only be accessed by lvalues of its (anonymous) type but the APR_RING_SENTINEL() macro defined like so: #define APR_RING_SENTINEL(hp, elem, link) \ (struct elem *)((char *)(&(hp)->next) - APR_OFFSETOF(struct elem, link)) casts the address of list's next member minus some constant to a pointer to struct apr_bucket and that pointer is then used to access the prev pointer.

* Follow up to r1895106: Use less expensive atomics for wakeup.ylavic2021-11-191-1/+1
| | | | | | | | | | | | | | | | | | If pipe writers (wakeup) put a single byte until it's consumed by the reader (drain), it's enough to use an atomic cas for the writers (still) and an atomic (re)set for the reader (no more cas here). This requires that the reader never blocks on read though (e.g. spurious return from poll), so make the read side on the pipe non-blocking again/finally. Since synchronous non-blocking read is not a thing for Windows' Readfile(), add a ->socket flag to this arch's apr_file_t (like the existing ->pipe one) which file_socket_pipe_create() will set to make apr_file_read/write() handle non-blocking (nor overlapped) socket pipes with WSARecv/Send(). git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1895175 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | This is requirement for unix systems, and otherwise can cause failures or undefined behaviour with some filesystems. Add apr_mmap_t->poffset on unixes to track the offset to the previous page, relative to the user requested/actual offset. This allows ->mm and ->size to still point to the actual data, while munmap() now deletes the full range from the start of the page. Tests updated accordingly. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1887060 13f79535-47bb-0310-9956-ffa450edef68
* apr_thread: destroy the thread's pool at _join() time, unless _detach()ed.ylavic2020-12-034-0/+4
| | | | | | | | | | | | | | 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(). git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1884077 13f79535-47bb-0310-9956-ffa450edef68
