|
||||
# The boost threading library can be built on top of different API's
|
||||
# Currently this is the win32 API and the pthreads API.
|
||||
# Pthread is native on unix variants.
|
||||
# To get pthread on windows you need the pthread win32 library
|
||||
# http://sourceware.org/pthreads-win32 which is available under LGPL.
|
||||
#
|
||||
# You need to provide the include path and lib path in the variables
|
||||
# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
|
||||
# paths in site-config.jam, user-config.jam or in the environment.
|
||||
# A new feature is provided to request a specific API:
|
||||
# <threadapi>win32 and <threadapi)pthread.
|
||||
#
|
||||
# The naming of the resulting libraries is mostly the same for the
|
||||
# variant native to the build platform, i.e.
|
||||
# boost_thread and the boost specific tagging.
|
||||
# For the library variant that is not native on the build platform
|
||||
# an additional tag is applied:
|
||||
# boost_thread_pthread for the pthread variant on windows, and
|
||||
# boost_thread_win32 for the win32 variant (likely when built on cygwin).
|
||||
#
|
||||
# To request the pthread variant on windows, from boost root you would
|
||||
# say e.g:
|
||||
# bjam msvc-8.0 --with-thread install threadapi=pthread

[section:acknowledgements Acknowledgments]
|
||||
|
||||
The original implementation of __boost_thread__ was written by William Kempf, with contributions from numerous others. This new
|
||||
version initially grew out of an attempt to rewrite __boost_thread__ to William Kempf's design with fresh code that could be
|
||||
released under the Boost Software License. However, as the C++ Standards committee have been actively discussing standardizing a
|
||||
thread library for C++, this library has evolved to reflect the proposals, whilst retaining as much backwards-compatibility as
|
||||
possible.
|
||||
|
||||
Particular thanks must be given to Roland Schwarz, who contributed a lot of time and code to the original __boost_thread__ library,
|
||||
and who has been actively involved with the rewrite. The scheme for dividing the platform-specific implementations into separate
|
||||
directories was devised by Roland, and his input has contributed greatly to improving the quality of the current implementation.
|
||||
|
||||
Thanks also must go to Peter Dimov, Howard Hinnant, Alexander Terekhov, Chris Thomasson and others for their comments on the
|
||||
implementation details of the code.

[section:barriers Barriers]
|
||||
|
||||
A barrier is a simple concept. Also known as a ['rendezvous], it is a synchronization point between multiple threads. The barrier is
|
||||
configured for a particular number of threads (`n`), and as threads reach the barrier they must wait until all `n` threads have
|
||||
arrived. Once the `n`-th thread has reached the barrier, all the waiting threads can proceed, and the barrier is reset.

[section:changes Changes since boost 1.35]
|
||||
|
||||
The 1.36.0 release of Boost includes a few new features in the thread library:
|
||||
|
||||
* New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once.
|
||||
|
||||
* Rvalue reference support for move semantics where the compilers supports it.
|
||||
|
||||
* A few bugs fixed and missing functions added (including the serious win32 condition variable bug).
|
||||
|
||||
* `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases.
|
||||
|
||||
* Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor.
|
||||
|
||||
* Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts.
|
||||
|
||||
[heading Changes since boost 1.34]
|
||||
|
||||
Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface
|
||||
changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking
|
||||
changes are described below.
|
||||
|
||||
[heading New Features]
|
||||
|
||||
* Instances of __thread__ and of the various lock types are now movable.
|
||||
|
||||
* Threads can be interrupted at __interruption_points__.
|
||||
|
||||
* Condition variables can now be used with any type that implements the __lockable_concept__, through the use of
|
||||
`boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards
|
||||
compatibility). `boost::condition_variable` is provided as an optimization, and will only work with
|
||||
`boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`).
|
||||
|
||||
* Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can
|
||||
be used as keys in associative containers, as they have the full set of comparison operators.
|
||||
|
||||
* Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and
|
||||
with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only.
|
||||
|
||||
* Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and
|
||||
`boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly
|
||||
available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types.
|
||||
|
||||
[heading Breaking Changes]
|
||||
|
||||
The list below should cover all changes to the public interface which break backwards compatibility.
|
||||
|
||||
* __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`,
|
||||
but is no longer a separate class.
|
||||
|
||||
* __recursive_try_mutex__ has been removed, and the functionality subsumed into
|
||||
__recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class.
|
||||
|
||||
* `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work,
|
||||
as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member
|
||||
functions.
|
||||
|
||||
* `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases,
|
||||
``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex,
|
||||
but did not lock it on construction. This facility has now been replaced with the constructor that takes a
|
||||
`boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);``
|
||||
|
||||
* The `locked()` member function of the `scoped_lock` types has been renamed to __owns_lock_ref__.
|
||||
|
||||
* You can no longer obtain a __thread__ instance representing the current thread: a default-constructed __thread__ object is not
|
||||
associated with any thread. The only use for such a thread object was to support the comparison operators: this functionality has
|
||||
been moved to __thread_id__.
|
||||
|
||||
* The broken `boost::read_write_mutex` has been replaced with __shared_mutex__.
|
||||
|
||||
* __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms.
|
||||
|
||||
* When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only
|
||||
unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests.

[section:condvar_ref Condition Variables]
|
||||
|
||||
[heading Synopsis]
|
||||
|
||||
The classes `condition_variable` and `condition_variable_any` provide a
|
||||
mechanism for one thread to wait for notification from another thread that a
|
||||
particular condition has become true. The general usage pattern is that one
|
||||
thread locks a mutex and then calls `wait` on an instance of
|
||||
`condition_variable` or `condition_variable_any`. When the thread is woken from
|
||||
the wait, then it checks to see if the appropriate condition is now true, and
|
||||
continues if so. If the condition is not true, then the thread then calls `wait`
|
||||
again to resume waiting. In the simplest case, this condition is just a boolean
|
||||
variable:
|
||||
|
||||
boost::condition_variable cond;
|
||||
boost::mutex mut;
|
||||
bool data_ready;
|
||||
|
||||
void process_data();
|
||||
|
||||
void wait_for_data_to_process()
|
||||
{
|
||||
boost::unique_lock<boost::mutex> lock(mut);
|
||||
while(!data_ready)
|
||||
{
|
||||
cond.wait(lock);
|
||||
}
|
||||
process_data();
|
||||
}
|
||||
|
||||
Notice that the `lock` is passed to `wait`: `wait` will atomically add the
|
||||
thread to the set of threads waiting on the condition variable, and unlock the
|
||||
mutex. When the thread is woken, the mutex will be locked again before the call
|
||||
to `wait` returns. This allows other threads to acquire the mutex in order to
|
||||
update the shared data, and ensures that the data associated with the condition
|
||||
is correctly synchronized.
|
||||
|
||||
In the mean time, another thread sets the condition to `true`, and then calls
|
||||
either `notify_one` or `notify_all` on the condition variable to wake one
|
||||
waiting thread or all the waiting threads respectively.
|
||||
|
||||
void retrieve_data();
|
||||
void prepare_data();
|
||||
|
||||
void prepare_data_for_processing()
|
||||
{
|
||||
retrieve_data();
|
||||
prepare_data();
|
||||
{
|
||||
boost::lock_guard<boost::mutex> lock(mut);
|
||||
data_ready=true;
|
||||
}
|
||||
cond.notify_one();
|
||||
}
|
||||
|
||||
Note that the same mutex is locked before the shared data is updated, but that
|
||||
the mutex does not have to be locked across the call to `notify_one`.
|
||||
|
||||
This example uses an object of type `condition_variable`, but would work just as
|
||||
well with an object of type `condition_variable_any`: `condition_variable_any`
|
||||
is more general, and will work with any kind of lock or mutex, whereas
|
||||
`condition_variable` requires that the lock passed to `wait` is an instance of
|
||||
`boost::unique_lock<boost::mutex>`. This enables `condition_variable` to make
|
||||
optimizations in some cases, based on the knowledge of the mutex type;
|
||||
`condition_variable_any` typically has a more complex implementation than
|
||||
`condition_variable`.

[section:overview Overview]
|

|

__boost_thread__ enables the use of multiple threads of execution with shared data in portable C++ code. It provides classes and
|
||||
functions for managing the threads themselves, along with others for synchronizing data between the threads or providing separate
|
||||
copies of data specific to individual threads.
|
||||
|
||||
The __boost_thread__ library was originally written and designed by William E. Kempf. This version is a major rewrite designed to
|
||||
closely follow the proposals presented to the C++ Standards Committee, in particular
|
||||

In order to use the classes and functions described here, you can

each class or function, or include the master thread library header:

[section:time Date and Time Requirements]
|
||||
|
||||
As of Boost 1.35.0, the __boost_thread__ library uses the [link date_time Boost.Date_Time] library for all operations that require a
|
||||
time out. These include (but are not limited to):
|
||||
|
||||
* __sleep__
|
||||
* __timed_join__
|
||||
* __cond_timed_wait__
|
||||
* __timed_lock_ref__
|
||||
|
||||
For the overloads that accept an absolute time parameter, an object of type [link thread.time.system_time `boost::system_time`] is
|
||||
required. Typically, this will be obtained by adding a duration to the current time, obtained with a call to [link
|
||||
thread.time.get_system_time `boost::get_system_time()`]. e.g.
|
||||
|
||||
boost::system_time const timeout=boost::get_system_time() + boost::posix_time::milliseconds(500);
|
||||
|
||||
extern bool done;
|
||||
extern boost::mutex m;
|
||||
extern boost::condition_variable cond;
|
||||
|
||||
boost::unique_lock<boost::mutex> lk(m);
|
||||
while(!done)
|
||||
{
|
||||
if(!cond.timed_wait(lk,timeout))
|
||||
{
|
||||
throw "timed out";
|
||||
}
|
||||
}
|
||||
|
||||
For the overloads that accept a ['TimeDuration] parameter, an object of any type that meets the [link
|
||||
date_time.posix_time.time_duration Boost.Date_Time Time Duration requirements] can be used, e.g.
|
||||
|
||||
boost::this_thread::sleep(boost::posix_time::milliseconds(25));
|
||||
|
||||
boost::mutex m;
|
||||
if(m.timed_lock(boost::posix_time::nanoseconds(100)))

||||
{

[section Thread Local Storage]
|
||||
|
||||
[heading Synopsis]
|
||||
|
||||
Thread local storage allows multi-threaded applications to have a separate instance of a given data item for each thread. Where a
|
||||
single-threaded application would use static or global data, this could lead to contention, deadlock or data corruption in a
|
||||
multi-threaded application. One example is the C `errno` variable, used for storing the error code related to functions from the
|
||||
Standard C library. It is common practice (and required by POSIX) for compilers that support multi-threaded applications to provide
|
||||
a separate instance of `errno` for each thread, in order to avoid different threads competing to read or update the value.
|
||||
|
||||
Though compilers often provide this facility in the form of extensions to the declaration syntax (such as `__declspec(thread)` or
|
||||
`__thread` annotations on `static` or namespace-scope variable declarations), such support is non-portable, and is often limited in
|
||||
some way, such as only supporting POD types.
|
||||
|
||||
[heading Portable thread-local storage with `boost::thread_specific_ptr`]
|
||||
|
||||
`boost::thread_specific_ptr` provides a portable mechanism for thread-local storage that works on all compilers supported by
|
||||
__boost_thread__. Each instance of `boost::thread_specific_ptr` represents a pointer to an object (such as `errno`) where each
|
||||
thread must have a distinct value. The value for the current thread can be obtained using the `get()` member function, or by using
|
||||
the `*` and `->` pointer deference operators. Initially the pointer has a value of `NULL` in each thread, but the value for the
|
||||
current thread can be set using the `reset()` member function.
|
||||
|
||||
If the value of the pointer for the current thread is changed using `reset()`, then the previous value is destroyed by calling the
|
||||
cleanup routine. Alternatively, the stored value can be reset to `NULL` and the prior value returned by calling the `release()`
|
||||
member function, allowing the application to take back responsibility for destroying the object.
|
||||
|
||||
[heading Cleanup at thread exit]
|
||||
|
||||
When a thread exits, the objects associated with each `boost::thread_specific_ptr` instance are destroyed. By default, the object
|
||||
pointed to by a pointer `p` is destroyed by invoking `delete p`, but this can be overridden for a specific instance of
|
||||
`boost::thread_specific_ptr` by providing a cleanup routine to the constructor. In this case, the object is destroyed by invoking
|
||||
`func(p)` where `func` is the cleanup routine supplied to the constructor. The cleanup functions are called in an unspecified
|
||||
order. If a cleanup routine sets the value of associated with an instance of `boost::thread_specific_ptr` that has already been
|
||||
cleaned up, that value is added to the cleanup list. Cleanup finishes when there are no outstanding instances of
|
||||
`boost::thread_specific_ptr` with values.

|

// 6 Jun 01
|

// WEKEMPF Initial version.
|

// 30 May 02 WEKEMPF
|

// Added interface to set specific cleanup handlers.
|
||||
// Removed TLS slot limits from most implementations.
|
||||
// 22 Mar 04 GlassfordM for WEKEMPF
|
||||
// Fixed: thread_specific_ptr::reset() doesn't check error returned
|
||||
// by tss::set(); tss::set() now throws if it fails.
|
||||
// Fixed: calling thread_specific_ptr::reset() or
|
||||
// thread_specific_ptr::release() causes double-delete: once on
|
||||
// reset()/release() and once on ~thread_specific_ptr().
