Removes a condition in Throttle::_reset_max by which the waiting queue is only
Signal()ed if the new maximum is lower than the current maximum.
There is no evidence of a use case where such a restriction would be
useful. In addition waking up a thread when the maximum increases
gives it a chance to immediately continue the suspended process
instead of waiting for the next put().
Create a new test file covering 100% of src/Throttle.{cc,h} lines of code.
The following methods are tested:
* Throttle::Throttle with and without a maximum
* Throttle::~Throttle when each pending Cond is deleted
* Throttle::take
* Throttle::get when updating the maximum ( lower or higher ),
when going to sleep waiting for the count to lower under
the maximum, when going to sleep because another thread is
already asleep waiting
* Throttle::get_or_fail when there is no maximum,
when requesting a count that is larger than the maximum, either
when the current value is under the maximum or above the maximum.
* Throttle::wait when used to reset the maximum and wake up
another thread asleep waiting
All asserts checking the arguments sanity are exercised ( negative argument
for Throttle::take etc. ).
Adds the LGPLv2+ licensing terms to COPYING along with the others.
Adds a Contributors section to the AUTHORS file.
Notes:
Testing asserts outputs verbose error messages that should be silenced
but it does not seem possible.
