test/fiber/test_queue.rb: Make the stuck test fail. (#8791) test/fiber/test_queue.rb: Make the stuck tests fail. We observed the 2 tests in the `test/fiber/test_queue.rb` getting stuck in some GCC compilers in Ubuntu ppc64le focal/jammy, even when the timeout `queue.pop(timeout: 0.0001)` is set in the code. This commit is to make the tests fail rather than getting stuck. --- test/fiber/test_queue.rb | 20 ++++++++++++++++---- 1 file changed, 16 insertions(+), 4 deletions(-)

2022-11-17Add support for `sockaddr_un` on Windows. (#6513)Samuel Williams
* Windows: Fix warning about undefined if_indextoname() * Windows: Fix UNIXSocket on MINGW and make .pair more reliable * Windows: Use nonblock=true for read tests with scheduler * Windows: Move socket detection from File.socket? to File.stat Add S_IFSOCK to Windows and interpret reparse points accordingly. Enable tests that work now. * Windows: Use wide-char functions to UNIXSocket This fixes behaviour with non-ASCII characters. It also fixes deletion of temporary UNIXSocket.pair files. * Windows: Add UNIXSocket tests for specifics of Windows impl. * Windows: fix VC build due to missing _snwprintf Avoid usage of _snwprintf, since it fails linking ruby.dll like so: linking shared-library x64-vcruntime140-ruby320.dll x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol snwprintf x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol vsnwprintf_l whereas linking miniruby.exe succeeds. This patch uses snprintf on the UTF-8 string instead. Also remove branch GetWindowsDirectoryW, since it doesn't work. * Windows: Fix dangling symlink test failures Co-authored-by: Lars Kanis <kanis@comcard.de> Notes: Merged-By: ioquatix <samuel@codeotaku.com>

2022-05-08Use a proper mutex for autoloading features. (#5788)Samuel Williams
Object#autoload implements a custom per-thread "mutex" for blocking threads waiting on autoloading a feature. This causes problems when used with the fiber scheduler. We swap the implementation to use a Ruby mutex which is fiber aware. Notes: Merged-By: ioquatix <samuel@codeotaku.com>
2022-01-19`rb_fiber_terminate` must not return [Bug #18497]Nobuyoshi Nakada
In a forked process from a fiber, the fiber becomes the only fiber, `fiber_switch` does nothing as there is no other fibers, `rb_fiber_terminate` does not terminate the fiber. In that case, reaches the end of `fiber_entry` finaly, which is declared as "COROUTINE" and should never return. Notes: Merged: https://github.com/ruby/ruby/pull/5468

2021-08-26Fix example fiber scheduler reg. writable eventsLars Kanis
There were two issues: 1. When an IO object is waiting for writablility only (as in test_tcp_accept) the selected hash is empty. Therefore selected[fiber] returns nil but needs to default to 0 in order to be or'ed with IO::WRITABLE. 2. When an IO object is waiting for read- or writability (as in test_tcp_connect), but only one of these two events arrive, the Fiber and IO object need to be removed from the other `@readable` or `@writable` list.

2021-08-03Fix potential hang when joining threads.Samuel Williams
If the thread termination invokes user code after `th->status` becomes `THREAD_KILLED`, and the user unblock function causes that `th->status` to become something else (e.g. `THREAD_RUNNING`), threads waiting in `thread_join_sleep` will hang forever. We move the unblock function call to before the thread status is updated, and allow threads to join as soon as `th->value` becomes defined. This reverts commit 6505c77501f1924571b2fe620c5c7b31ede0cd22. Notes: Merged: https://github.com/ruby/ruby/pull/4689

2021-06-14Wake up join list within thread EC context. (#4471)Samuel Williams
* Wake up join list within thread EC context. * Consume items from join list so that they are not re-executed. If `rb_fiber_scheduler_unblock` raises an exception, it can result in a segfault if `rb_threadptr_join_list_wakeup` is not within a valid EC. This change moves `rb_threadptr_join_list_wakeup` into the thread's top level EC which initially caused an infinite loop because on exception will retry. We explicitly remove items from the thread's join list to avoid this situation. * Verify the required scheduler interface. * Test several scheduler hooks methods with broken `unblock` implementation.
