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.

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.

Sönke Ludwig c8f95f324b Enable canceling win32 file I/O.
The CancelIOEx call was disabled just due to historical reasons.

Remove static compiler __VERSION check. "import core.sys.dragonflybsd.netinet.in_" will work, when compiler support is there.

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.

The reference count was one too high and the waiter count was not properly decremented when an event got destroyed.

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().

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.

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.

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.
