Merge pull request #65 from vibe-d/fix_eventfd_leak
Fix leaked eventfd in PosixEventDriverCore.
2018-03-14 22:19:00 +01:00
Sönke Ludwig b6b32f4a49 Fix leaked eventfd in PosixEventDriverCore.
The leak occurred once per thread, which showed up in conjunction with DNS lookups in particular, as a thread is currently created for each lookup.

Sönke Ludwig 4192d31716 Create the event object in ThreadedFileEventDriver lazily.
Avoids creating event objects for every worker thread, even if never used.

Sönke Ludwig 53bb8eeead Fix cleanup code for directory watchers in the WinAPI driver.
- Fixes an assertion triggered by accessing a file field in releaseRef

- Fixed a potential leak of file system watcher handles when calling releaseRef from inside the supplied callback - this was the reason why the fixed assertion error wasn't triggered by the test code

Merge pull request #60 from vibe-d/single_file_taskpool
Use a single thread pool for all threaded file driver threads.
2018-03-11 23:36:34 +01:00
Sönke Ludwig f094b3934b Make sure that no obsolete I/O events get processed.
Removes overlapped I/O events when a handle gets closed prematurely (before all events have been processed) to avoid potential range violation errors as a consequence.

Sönke Ludwig 26907c7489 Fix set up of OVERLAPPED struct for files. 2018-03-11 20:31:44 +01:00
Sönke Ludwig 3090bc2c7c Implement filterPending for ConsumableQueue. 2018-03-11 20:31:44 +01:00
Sönke Ludwig f5f64ee476 Use a single thread pool for all threaded file driver threads.
This avoids multiplying the number of threads by 5 for each thread that performs file I/O.

Sönke Ludwig df78af96bb Use a custom nogc_assert in cleanup code.
Unfortunately the built-in assert GC allocates an exception, which means that if called directly or indirectly form a finalizer, the assertion will not become visible and instead an InvalidMemoryOperationError is thrown.

This implements a custom nogc_assert() function that directly prints the assertion message and uses abort() to end the process.

Sönke Ludwig 9dc8b796e5 Get rid of OVERLAPPED_FILE.
The hEvent member is currently unused for files. Using it for the file handle makes the OVERLAPPED_CORE struct sufficient.

Sönke Ludwig 0e1d74cc41 Call Windows IO callbacks outside of completion routines.
Calling WinSock functions from inside of a completion routine results in undefined behavior, because the completion routine may be triggered within another WinSock function that enters an alertable wait state. For this reason, none of the callbacks that are triggered by overlapped I/O may be invoked directly from a completion routine.

To solve this, a ConsumableQueue is filled with all completion events that occur and is processed after each MsgWaitForMultipleObjectsEx call.

Sönke Ludwig 0b02c84b2b Set ConnectionState.connected when accepting a connection. Fixes #54. 2018-03-07 11:00:03 +01:00
Sönke Ludwig 008163e913 Fix setTCPNoDelay/setKeepAlive and add assertions.
Assertions make sure that socket query functions are not called with an invalid handle (resulting in strange out-of-memory errors).

Sönke Ludwig 43ef41d4fa Fix deprecation warning on DMD 2.079.0. 2018-03-06 20:09:03 +01:00
Sönke Ludwig 3d2a2656bb Robustness fix for WinAPIEventDriverWatchers.
Under certain (rare) circumstances, the receive buffer contains data from a file instead of the expected FILE_NOTIFY_INFORMATION structure. No signs of handle or buffer reuse could be found, so the cause for this remains unclear. Until the cause can be narrowed down, this keeps the issue visible while avoiding to crash the application.

Sönke Ludwig fbd6927377 Improve robustness of file I/O callbacks for the WinAPI driver.
Explicitly gets the read/write slot from the handle map from within the callback instead of dereferencing the pointer assigned when starting the operation. This makes sure that no dangling reference is accessed. Instead, if the slot got reused before the callback is invoked (which is a bug), an assertion will be triggered if the slot now has a different handle type.

Sönke Ludwig 3a52e0f362 Fix cast from HANDLE to descriptor in the WinAPI driver.
Avoids truncation to 32-bit for 64-bit builds. Also improves robustness of the directory watcher shutdown procedure.

Fix watcher cancellation
2018-02-22 01:56:13 +01:00
Sönke Ludwig 0e7091d085 Fix invalid watcher slot access in the win32 driver.
The underlying file handle and the associated slot could previously be destroyed before the I/O callback had been finally called. Now the callback itself is responsible to destroying the handle.
2018-02-22 01:14:31 +01:00
Sönke Ludwig c8f95f324b Enable canceling win32 file I/O.
The CancelIOEx call was disabled just due to historical reasons.

Sönke Ludwig 9ca1a4c3a6 Fix inotify based directory watcher for recursive directory adds.
Newly added folders were not scanned recursively, which would result in sub folders that already exist or are added concurrently to not be watched.

Sönke Ludwig 29aee9ee52 Defer driver dispose in main thread to shared static ~this.
Allows dependent code to still access the driver from within their shared static ~this. vibe-core notably falls into this category.

Sönke Ludwig aa9a08f571 Explicitly dispose the event driver on thread shutdown.
Handle multiple calls to dispose() gracefully, because external code may already make an explicit call to dispose().
