# Build instructions for libcubeb
|
||||
|
||||
You must have CMake v3.1 or later installed.
|
||||
|
||||
1. `git clone --recursive https://github.com/kinetiknz/cubeb.git`
|
||||
2. `mkdir cubeb-build`
|
||||
3. `cd cubeb-build`
|

# Windows build notes
|
||||
|
||||
Windows builds can use Microsoft Visual Studio 2015 (the default) or MinGW-w64
|
||||
with Win32 threads (by passing `cmake -G` to generate the appropriate build
|
||||
configuration). To build with MinGW-w64, install the following items:
|
||||
|
||||
- Download and install MinGW-w64 with Win32 threads.
|
||||
- Download and install CMake.
|
||||
- Run MinGW-w64 Terminal from the Start Menu.
|
||||
- Follow the build steps above, but at step 3 run:
|
||||
`cmake -G "MinGW Makefiles" ..`
|
||||
- Continue the build steps above.

# sanitizers-cmake
|
||||
|
||||
[![](https://img.shields.io/github/issues-raw/arsenm/sanitizers-cmake.svg?style=flat-square)](https://github.com/arsenm/sanitizers-cmake/issues)
|
||||
[![MIT](http://img.shields.io/badge/license-MIT-blue.svg?style=flat-square)](LICENSE)
|
||||
|
||||
CMake module to enable sanitizers for binary targets.
|
||||
|
||||
|
||||
## Include into your project
|
||||
|
||||
To use [FindSanitizers.cmake](cmake/FindSanitizers.cmake), simply add this repository as git submodule into your own repository
|
||||
```Shell
|
||||
mkdir externals
|
||||
git submodule add git://github.com/arsenm/sanitizers-cmake.git externals/sanitizers-cmake
|
||||
```
|
||||
and adding ```externals/sanitizers-cmake/cmake``` to your ```CMAKE_MODULE_PATH```
|
||||
```CMake
|
||||
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/externals/sanitizers-cmake/cmake" ${CMAKE_MODULE_PATH})
|
||||
```
|
||||
|
||||
If you don't use git or dislike submodules you can copy the files in [cmake directory](cmake) into your repository. *Be careful and keep updates in mind!*
|
||||
|
||||
Now you can simply run ```find_package``` in your CMake files:
|
||||
```CMake
|
||||
find_package(Sanitizers)
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
You can enable the sanitizers with ``SANITIZE_ADDRESS``, ``SANITIZE_MEMORY``, ``SANITIZE_THREAD`` or ``SANITIZE_UNDEFINED`` options in your CMake configuration. You can do this by passing e.g. ``-DSANITIZE_ADDRESS=On`` on your command line or with your graphical interface.
|
||||
|
||||
If sanitizers are supported by your compiler, the specified targets will be build with sanitizer support. If your compiler has no sanitizing capabilities (I asume intel compiler doesn't) you'll get a warning but CMake will continue processing and sanitizing will simply just be ignored.
|
||||
|
||||
#### Compiler issues
|
||||
|
||||
Different compilers may be using different implementations for sanitizers. If you'll try to sanitize targets with C and Fortran code but don't use gcc & gfortran but clang & gfortran, this will cause linking problems. To avoid this, such problems will be detected and sanitizing will be disabled for these targets.
|
||||
|
||||
Even C only targets may cause problems in certain situations. Some problems have been seen with AddressSanitizer for preloading or dynamic linking. In such cases you may try the ``SANITIZE_LINK_STATIC`` to link sanitizers for gcc static.
|
||||
|
||||
|
||||
|
||||
## Build targets with sanitizer support
|
||||
|
||||
To enable sanitizer support you simply have to add ``add_sanitizers(<TARGET>)`` after defining your target. To provide a sanitizer blacklist file you can use the ``add_sanitizer_blacklist(<FILE>)`` function:
|
||||
```CMake
|
||||
find_package(Sanitizers)
|
||||
|
||||
add_sanitizer_blacklist("blacklist.txt")
|
||||
|
||||
add_executable(some_exe foo.c bar.c)
|
||||
add_sanitizers(some_exe)
|
||||
|
||||
add_library(some_lib foo.c bar.c)
|
||||
add_sanitizers(some_lib)
|
||||
```
|
||||
|
||||
## Run your application
|
||||
|
||||
The sanitizers check your program, while it's running. In some situations (e.g. LD_PRELOAD your target) it might be required to preload the used AddressSanitizer library first. In this case you may use the ``asan-wrapper`` script defined in ``ASan_WRAPPER`` variable to execute your application with ``${ASan_WRAPPER} myexe arg1 ...``.

/**
|

* Single producer single consumer lock-free and wait-free ring buffer.
|
||||
*
|
||||
* This data structure allows producing data from one thread, and consuming it on
|
||||
* another thread, safely and without explicit synchronization. If used on two
|
||||
* threads, this data structure uses atomics for thread safety. It is possible
|
||||
* to disable the use of atomics at compile time and only use this data
|
||||
* structure on one thread.
|
||||
*
|
||||
* The role for the producer and the consumer must be constant, i.e., the
|
||||
* producer should always be on one thread and the consumer should always be on
|
||||
* another thread.
|
||||
*
|
||||
* Some words about the inner workings of this class:
|
||||
* - Capacity is fixed. Only one allocation is performed, in the constructor.
|
||||
* When reading and writing, the return value of the method allows checking if
|
||||
* the ring buffer is empty or full.
|
||||
* - We always keep the read index at least one element ahead of the write
|
||||
* index, so we can distinguish between an empty and a full ring buffer: an
|
||||
* empty ring buffer is when the write index is at the same position as the
|
||||
* read index. A full buffer is when the write index is exactly one position
|
||||
* before the read index.
|
||||
* - We synchronize updates to the read index after having read the data, and
|
||||
* the write index after having written the data. This means that the each
|
||||
* thread can only touch a portion of the buffer that is not touched by the
|
||||
* other thread.
|
||||
* - Callers are expected to provide buffers. When writing to the queue,
|
||||
* elements are copied into the internal storage from the buffer passed in.
|
||||
* When reading from the queue, the user is expected to provide a buffer.
|
||||
* Because this is a ring buffer, data might not be contiguous in memory,
|
||||
* providing an external buffer to copy into is an easy way to have linear
|
||||
* data for further processing.
