* Use a semaphore to signal the event handlerChris Robinson2018-02-012-16/+5
| | | | | | | | | | | Semaphores allow for semi-persistent signals, compared to a condition variable which requires a mutex for proper detection. A semaphore can be 'post'ed after writing some data on one thread, and another thread will be able to recognize it quickly even if the post occured in between checking for data and waiting. This more correctly fixes a race condition with events since the mixer shouldn't be using mutexes, and arbitrary wake-ups just to make sure an event wasn't missed was quite inefficient.
* Send buffer completed events when enabledChris Robinson2018-02-011-1/+1

* Fix check for matching event typeChris Robinson2018-02-011-1/+1
|
* Add a thread to marshal events from the mixerChris Robinson2018-01-312-3/+86
| | | | | | To avoid having unknown user code running in the mixer thread that could significantly delay the mixed output, a lockless ringbuffer is used for the mixer to provide events that a secondary thread will pop off and process.
* Rename EventLock to make it more clear it's protecting the callbackChris Robinson2018-01-304-9/+7

* Fix the effect slot limit checkChris Robinson2018-01-281-1/+1
|
* Make EnabledEvts atomicChris Robinson2018-01-284-7/+26

* Report the problem value for global state errorsChris Robinson2018-01-281-21/+22
|
* Use a fixed array for the effect state factory listChris Robinson2018-01-282-31/+24
|
* Don't bother with a return value that's never usedChris Robinson2018-01-272-7/+6
|
* Don't allocate more effect slots than allowedChris Robinson2018-01-271-0/+8
|
* Move some inline functions into a header instead of copying themChris Robinson2018-01-275-35/+36
| | | | | Unfortunately does not include the Lookup* functions, which need the full type declaration to offset the pointer.
* Fix error reporting for resource generationChris Robinson2018-01-274-12/+16
|
* Store filters in an array of listsChris Robinson2018-01-274-82/+164
|
* Store effects in an array of listsChris Robinson2018-01-274-79/+160
|
* Use a vector to store the effect slot pointersChris Robinson2018-01-274-81/+103
| | | | And make the ID a simple index into it (1-base, to avoid ID 0).
* Use an array lookup for source IDsChris Robinson2018-01-272-125/+204
| | | | | This is now similar to buffers, being stored in groups of 64 in a vector with the ID providing the array indices.
* Make some more functions static where they're usedChris Robinson2018-01-272-21/+14
|
* Add some casts to pacify MSVCChris Robinson2018-01-273-5/+6
|
* Add a ctz64 fallback using _BitScanForward when availableChris Robinson2018-01-271-1/+15
|
* Check for _BitScanForward64 before using itChris Robinson2018-01-271-4/+4
|
* Use a different method for storing and looking up buffersChris Robinson2018-01-274-100/+214
| | | | | | | | | | | | | | | | | Rather than each buffer being individually allocated with a generated 'thunk' ID that's used with a uint:ptr map, buffers are allocated in arrays of 64 within a vector. Each group of 64 has an associated 64-bit mask indicating which are free to use, and the buffer ID is comprised of the two array indices which directly locate the buffer (no searching, binary or otherwise). Currently no buffers are actually deallocated after being allocated, though they are reused. So an app that creates a ton of buffers once, then deletes them all and uses only a couple from then on, will have a bit of waste, while an app that's more consistent with the number of used buffers won't be a problem. This can be improved by removing elements of the containing vector that contain all-free buffers while there are plenty of other free buffers. Also, this method can easily be applied to other resources, like sources.

* Provide messages for the remaining AL errorsChris Robinson2018-01-2410-364/+371

* Set the buffer load error in LoadDataChris Robinson2018-01-242-42/+37
|
* Call the event callback when an error is generatedChris Robinson2018-01-246-104/+114
| | | | | Most errors don't yet provide correct object IDs or text messages for the AL error.
* Handle event propertiesChris Robinson2018-01-233-2/+137
| | | | | This just implements the event methods insofar as tracked state. No events are generated/reported yet.
* Declare the beginnings of an event extensionChris Robinson2018-01-231-0/+23
|
* Fix some 'may be used initialized' warningsChris Robinson2018-01-231-53/+54
|
* Use a new proper buffer function with a flags parameterChris Robinson2018-01-232-13/+16
| | | | | | Rather than hackily combining bit flags with the format, to increase the number of potential flags. alBufferData now behaves as if calling alBufferStorageSOFT with a flags value of 0.
* Ensure read or write flags are specified with persistent mappingsChris Robinson2018-01-231-4/+7
|
* Track the buffer's mapped sectionChris Robinson2018-01-232-3/+10
|
* Add a flag for persistent mappingChris Robinson2018-01-233-8/+49
| | | | And a function to "flush" a mapped buffer
* Slightly simplify alBufferSubDataSOFTChris Robinson2018-01-221-36/+13
|
* Ensure proper alignment when preserving data tooChris Robinson2018-01-221-2/+3
|
* Don't bother allocating cleared memory for buffer storageChris Robinson2018-01-221-1/+1
|
* Add a flag for alBufferData to non-destructively resize the dataChris Robinson2018-01-222-7/+25
| | | | | | Requires having the same format as the last call to alBufferData. Also only makes sense when given a NULL data pointer, as otherwise the internal data will be overwritten anyway.
* Don't convert/copy samples with a NULL dest bufferChris Robinson2018-01-221-6/+4
| | | | Only happens with a 0 size, so there's nothing to copy or convert anyway.
* More cleanup for buffer loadingChris Robinson2018-01-215-829/+112
| | | | | Don't bother with unnecessary and unused converters, and remove some unsupported queries.
* Handle double-precision buffers in the mixerChris Robinson2018-01-212-29/+8
|
* Remove support for (signed) byte and ushort sample storageChris Robinson2018-01-213-89/+24
| | | | Also not used without buffer_samples
