Merge pull request #140 from Cogitri/meson
Add support for building with meson
2020-05-11 17:06:42 +02:00
Sönke Ludwig 496e99c3b4 Make the API robust against using invalid handles. Fixes #105.
Introduces a "validationCounter" field for all handle types that gets incremented (at least) whenever an OS file descriptor/handle gets invalidated or re-allocated. This way, an old eventcore handle to a reused OS handle can always be distinguished from the current one to avoid interference.

Sönke Ludwig e8ed523c08 Fix transferred byte counter for windows stream socket reads/writes.
Fixes read/write sizes that are sometimes reported too small.

Sönke Ludwig b32b329d15 Fix the approach to determine connect failures.
On macOS it could happen that both, onConnect and onConnectError, were triggered, resulting in seemingly overlapping connection attempts when they really were sequential. This in turn triggered a connection error leak test in vibe-core.

Now using only the write-ready flag plus the reported socket error status to determine failed connections, guaranteeing a single call back.

Geod24 e7688361ba Let malloc infer its attributes
Malloc should not force '@safe' or '@nogc' on constructors which are not.
For example, TaskPool's ctor is not '@nogc' but was assumed as such
thanks to the delegate cast happening in malloc.
Likewise, the ctor or the arguments might not be '@safe',
or any other attributes, but they were be mistakenly marked as such.

Sönke Ludwig 14a896be5d Attempt to fix crash in thread based DNS lookup.
Depending on the timing of starting and finishing DNS queries, `Thread.join` could be called on an instance that had already been `destroy`ed. To avoid this, the thread instance is now explicitly set to null, as well as resetting the "done" field to avoid redundant work for unused slots.

See vibe-d/vibe.d#2378.

Sönke Ludwig 5255645455 Start a thread for each DNS lookup. Fixes vibe-d/vibe.d#2378.
std.parallelism.Task.executeInNewThread leaks the thread's resources instead of reusing it in later calls. As a workaround, this commit starts a new thread for every lookup and properly tears it down afterwards. At a later point, this code should be changed to reuse the thread(s), if possible, to avoid the startup overhead.

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 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 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.
