Sönke Ludwig 5c3afcc175 Ensure that a valid PID is passed to kill(). 2019-08-23 09:35:13 +02:00
Sönke Ludwig 01c2c26964 Fix Windows compilation.
Integrates the contents of StaticProcesses into PosixEventDriverProcesses to fully hide it form the Windows build. It also changes lockedProcessInfo to be a non-template function, as that lead to a linker error on macOS.

Sönke Ludwig f1c2eb779f Use the Posix process driver on all Posix operating systems. 2019-08-23 09:35:13 +02:00
Sönke Ludwig 7ebad49ed0 Rework the child process exit code to not rely in SIGCHLD.
It turns out that in a heterogeneous process where other parts of the code may start processes or threads and may be waiting for those to finish, it is not realistic to rely on signalfd or even SIGCHLD in general to get notified about child process exits. The only solid way appears to be to start a separate waiter thread that uses waitid/waitpid to wait for exited child processes in a blocking way.

This also fixes the hanging vibe.core.process test in vibe-core with DMD 2.087.x.

Sönke Ludwig 4724f14145 Avoid interference with other users of waitpid.
Instead of using waitpid(-1), explicitly waits on all known processes. This is inefficient for large numbers of child processes, but seems to be the only way to ensure to not interfere with other code that uses waitpid().

Sönke Ludwig 72234fc0a7 Return an invalid wait ID for processes.wait() if the process has already exited.
Avoids overlap with valid wait IDs, so that a paired cancelWait() doesn't cancel a different wait.

Sönke Ludwig 9bb6be87c3 Fix possible access of freed directory watcher entries.
This mainly affected macOS, which currently uses the polling directory watcher. Since entries were freed during the loop, the remaining keys could point to already freed entries.

v1ne c2708f1de8 winapi/files: Append to files with FILE_APPEND_DATA
Before, the mode GENERIC_WRITE was used. This tells Windows to not
append to the file, but overwrite it normally. This is not the intended
semantics. FILE_APPEND_DATA does what we want.

Sönke Ludwig 731936ce9e Separate the polling logic of PollEventDriverWatchers into a separate class.
Allows to keep thread-local state separate from the mutex-protected/immutable state in PollingThread to make sure that there are no unwanted accesses.

Sönke Ludwig 78db7c9573 Fix race-condition in ThreadedFileEventDriver.
The m_files field was accessed from the worker threads, which is unsafe, because the chunk index of the ChoppedVector could change at any time. The accessed field is now copied to the worker thread instead.

Also, instead of a custom spin lock, StaticTaskPool now uses a normal Mutex, which is just as fast, but emits the proper memory barriers and is integrated with LDC's thread sanitizer.

Sönke Ludwig 48d083b20f Fix possible race condition in PosixEventDriverEvents.trigger.
Accessing the event slot should only be done from the owner thread, since the chunk index of the ChoppedVector could be updated at any time. Instead of a triggerAll field, this flag is now propagated through the underlying eventfd/socket pair.

don't try to set the SO_REUSEPORT flag
On Linux this option was always set, regardless if the `StreamListenOptions` specifies it.

On some systems setting that option will result in a failure.

Sönke Ludwig b33f710420 Keep timers with active waits referenced.
Avoids calling the wait callback with reference count zero. In case of a non-pending timer, the wait will be canceled if the wait reference is the last one to avoid keeping starved timers.
