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.
 2018-03-11 20:32:32 +01:00
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.
 2018-03-11 14:46:55 +01:00
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.
 2018-03-11 13:56:10 +01:00
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.
 2018-03-11 00:27:14 +01:00
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.
 2018-03-10 22:59:21 +01:00
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).
 2018-03-07 10:52:01 +01:00
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.
 2018-03-03 20:04:51 +01:00
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.
 2018-03-03 19:56:54 +01:00
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.
 2018-03-03 19:56:54 +01:00
Sönke Ludwig e8e8f85271 Add DatagramSocket.broadcast property. Fixes #47. 2018-02-22 02:08:09 +01:00
Sönke Ludwig b2b072dd80 Reduce the number of ChoppedVector index operations. 2018-02-22 01:58:49 +01:00

Merge pull request #50 from vibe-d/fix_watcher_cancellation 
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.
 2017-12-02 02:54:13 +01:00
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.
 2017-11-25 16:59:53 +01:00
Sönke Ludwig 2d4ccf454d Properly increment waiter count for WinAPI file I/O operations. 2017-11-25 16:47:29 +01:00
Sönke Ludwig 07d2bafcac Fix threading issues in the generic Posix event implementation. 
Uses socketpair non-Linux systems and two separate UDP sockets on Windows for the cross-thread communication.

Sönke Ludwig 1d4fbc4fa2 Fixup poll driver. 2017-11-23 23:11:16 +01:00
Sönke Ludwig c8fd340240 Fix destruction of PosixEventDriverEvents event. 
The reference count was one too high and the waiter count was not properly decremented when an event got destroyed.
 2017-11-23 23:11:16 +01:00
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().
 2017-11-23 23:11:16 +01:00
Sönke Ludwig 16e95b03e8 Fix WinAPI watcher to be consistent. 2017-11-22 17:14:31 +01:00
Sönke Ludwig a9ae496fb4 Avoid "." path in InotifyEventDriverWatchers. 
The vibe-core tests broke because a "/./" path segment slipped into the resulting paths.

Sönke Ludwig 99088e1202 Implement a generic polling based directory watcher. 
This is used on platforms that don't have a specialized watcher implementation.
 2017-11-21 10:42:21 +01:00
Sönke Ludwig 815db0727c Change all invalid handle values to ~0 and improve FileChange. 
FileChange now has the full path of a file split into the base path (as specified when creating the watcher), the sub directory, and the file name. This allows to work with less dynamic memory allocations internally.
 2017-11-21 10:42:14 +01:00
Sönke Ludwig 3352423414 Fix decrementing the waiter count when destroying a WinAPI event with active waiters. 2017-11-21 00:09:41 +01:00

Sönke Ludwig 314bd2bb48 Fix WinAPI condition for outOfWaiters event loop exit reason. 
Calling processEvents could previously block indefinitely even if there were no waiters left.
 2017-11-20 15:59:35 +01:00
Sönke Ludwig 7cc6bec14a Fix a possible range error when a win32 file watcher gets destroyed while waiting. 
This is not a final solution, but avoids the fatal error and replaces it with, at worst, bogus change events being reported.

Sönke Ludwig c4550f0e59
Fix ThreadedFileEventDriver read/write issues. 
I/O errors were being reported as IOStatus.ok instead of IOStatus.error, and the I/O operation finalization protocol had a potential race-condition when storing the number of bytes processed.
 2017-10-30 22:54:14 +01:00
Sönke Ludwig 8799b7b01e Add assertion. 2017-09-26 15:49:13 +02:00
Sönke Ludwig 60407b783b Fix re-enqueuing of periodic timers. Fixes #25. 
Periodic timers were first re-enqueued and then removed, effectively causing them to stay at their old position, cutting off the tail of the timer queue.

Sönke Ludwig 06c6e0a4ca
Add basic UDP multicast support. 
This also adds a new setOption method to handle boolean socket options in a generic way.

Sönke Ludwig 07baa0f612
Improve performance of accepting incoming connections. 
- Removes the accept() loop, as that doesn't measurably improve performance in practice. This also gives each connection the possibility to perform initial I/O before more concurrency is generated by accepting the next connection.

- Uses SOCK_NONBLOCK in conjunction with socket() and accept4() to save one additional syscall per connection.
 2017-09-02 15:40:07 +02:00
Sönke Ludwig fc5df2f949
Use level-triggered events for listening stream sockets. 
The limit of 20 accepted connections per event invocation can otherwise lead to no more connections being accepted when more that 20 connections are available at a time. This is an adaptation of @Boris-Barboris pull request #21 to restrict the level triggered behavior to listening sockets. See also #20.

Sönke Ludwig eb595ef858 Fix always calling GC.addRange in ChoppedVector if necessary. 2017-08-26 22:33:00 +02:00
Sönke Ludwig 74352a9ac5 Avoid dangling socket slot access in the WinAPI driver. 
When the last reference got released while a blocking socket operation was still in progress, the old slot was still accessed from the completion callback, leading to null pointer accesses or other issues.

Sönke Ludwig a63907b9f7
Fix multiple bugs in ThreadedFileEventDriver. 
- Errors were reported as "ok"
- The cancel state logic was flawed and could lose cancel requests
- Operations could be removed from the active sets before they actually finished, causing the callback to never get called

Sönke Ludwig a7e5b49943 Implement basic UDP support for the WinAPI driver. 
Note that the IOMode.immediate semantics are not compatible with the current 0-udp.d test and will instead call the callback asynchronously. It appears that non-blocking semantics are generally not possible with overlapped sockets.

Sönke Ludwig a263637bd3 Fix WSASend/WSARecv usage w.r.t. WSABUF parameter. 
The documentation states that the buffer must be kept alive during the whole operation, so using a stack allocated buffer is illegal.

Sönke Ludwig ab796477e2 Move .userData to the socket driver. 
Generally each FD type should have its own .userData property in the respective driver. This is important for drivers that don't have a unified file descriptor space and need to store user data in a type specific way.
