As a consequence, the singleton implementation has to be made thread-safe.
Also implement the singleton pattern using a namespace, rather than a static
instance.
There were two implementations of integer exponentiation. Merge them into a new
file under utils/cc/.
By the way, optimize it using exponentiation by squaring.
We now use a initializer list constructor for creating symmetries of the form
$y^n$, $y^n u^m$, $y^nu^m\sigma^k$.
The constructor taking a single integer is used to initialize a symmetry of a
given length.
Similar changes are made to IntSequence.
This behavior is similar to std::vector.
Since the introduction of the --burn option (in Dynare++ shipped with Dynare
4.3.0), the IRFs reported by Dynare++ were wrong.
The IRFs are computed using a generalized IRF method: the result is
the (average) difference between a simulation with shock and a simulation
without shock. The problem was that the two simulations were not using the same
starting point.
Closes#1634
At the end of a thread, we must first notify the main thread waiting on the
condition variable, then unlock the mutex. We must do these two operations in
that order, otherwise there is a possibility of having the main process
destroying the condition variable before the thread tries to notify it (if all
other threads terminate at the same time and bring the counter down to zero).
For that reason, we cannot use std::notify_all_at_thread_exit().
Bug introduced in commit 752a02a36.
The material of this document comes from the introduction to the library that
had been lost in the move away from CWEB (formerly tl/cc/main.web).
This file gives a good overview of the library. It has been adapted from TeX to
LaTeX. Also I fixed a mistake in the Faà di Bruno's tensor formula.
On Windows, this means that a POSIX threads implementation is no longer needed,
since C++11 threads are implemented using native Windows threads.
On GNU/Linux and macOS, POSIX threads are still used under the hood.
A new m4 macro (AX_CXX11_THREAD) is used to add the proper compilation
flags (instead of AX_PTHREAD).
- Remove the GeneralMatrix(const ConstVector &) constructor, since it is hides
a memory allocation (copying the ConstVector into a fresh Vector). This
helped detecting and fixing several unneeded memory allocations. Some other
memory allocations are now more visible (with an explicit Vector{}
constructor).
- Add checks in GeneralMatrix(Vector, …) and ConstGeneralMatrix(ConstVector, …)
constructors for verifying that the {Const,}Vector has unit-stride (this was
an implicit assumption so far) and is large enough for storing rows*cols
elements.
- Add GeneralMatrix::operator=(const ConstGeneralMatrix &).
- Delete ConstGeneralMatrix::operator=().
Many BLAS/LAPACK calls were making the assumption that LD==rows when passing
matrices. In some cases this was correct (because of implementation details,
in particular because how the copy constructor of GeneralMatrix is implemented).
But in other cases it was a bug.
With this commit, the actual value for LD is systematically used (this fixes
existing bugs and prevent possible future ones if the implementation details
were changed).
