d7989f19cf Fix bug in bearing filter related to reverse edges. Fix tests to catch it. Still one outstanding test failure that looks like a problem in the viaroute results. 2015-11-18 10:57:20 -05:00

8f3482561b Rename great_circle_distance->haversine_distance, and euclidean_distance->great_circle_distance, because that's what they actually are. 2015-11-17 17:10:06 -05:00

1536d1c044 Add bearing filter support to viaroute, trip, nearest, and distance
table plugins.
Make bearing range configurable by adding a comma-separated second part
to the bearing paramenter, like so:

    b=<bearing:0-359>(,<range:0-180>)

If no range is supplied, it defaults to +/- 10 degrees.

d07c0bde80 Adds support for a new b= parameter on the viaroute and match
plugins, allowing for better nearest neighbor matching when a heading
is known.

6e6b38e8e9 Revert the usage of TBB's iterator pair taking overloads.
This reverts the range based overload usage introduced in @6b2bf495.

Old TBB versions do not provide the range overloads.

9231335eef Use Intel TBB's parallel_sort even for nested parallelism.
TBB has a global task scheduler (that's one of the reason TBB is not
linked statically but dyanmically instead). This allows control over all
running threads, enabling us to use nested parallelism and the scheduler
doing all the task allocation itself.

That is, nested parallel execution such as in

    parallel_for(seq, [](const auto& rng){
      parallel_sort(rng);
    });

is no problem at all, as the scheduler still claims control over the
global environment.

Therefore, use `parallel_sort` Range overload where possible.

397078758e Remove boost/thread from rtree, include header for hash_combine in unit test.
The `static_rtree.hpp` header included `<booost/thread.hpp>` without using
anything from this header.

Removing it showed why:

the unit test for the rtree no longer built, since it was missing symbols
for Boost's `hash_combine`, used in the unit test.

Instead of relying on `<boost/thread.hpp>` including the proper header
for `hash_combine` by chance that we only use in the unit test, do the
following:

- remove `<boost/thread.hpp>` from the rtree implementation
- add `<boost/functional/hash.hpp>` to the rtree unit test

As always, include what you use.

c9af06c9e0 Remove hand-written ConcurrentQueue class template.
We already rely on Intel TBB, which provides battle-tested
concurrency containers, such as:

- `concurrent_queue`,
- `concurrent_bounded_queue`,
- `concurrent_priority_queue`.

The `ConcurrentQueue` class template was never used. If the need
comes up again, we should strongly prefer those instead of writing
one ourselves.

94af9b7f13 Caches iterators instead of invoking function calls on every iteration.
This caches iterators, i.e. especially the end iterator when possible.

The problem:

    for (auto it = begin(seq); it != end(seq); ++it)

this has to call `end(seq)` on every iteration, since the compiler is
not able to reason about the call's site effects (to bad, huh).

Instead do it like this:

    for (auto it = begin(seq), end = end(seq); it != end; ++it)

caching the end iterator.

Of course, still better would be:

    for (auto&& each : seq)

if all you want is value semantics.

Why `auto&&` you may ask? Because it binds to everything and never copies!

Skim the referenced proposal (that was rejected, but nevertheless) for a
detailed explanation on range-based for loops and why `auto&&` is great.

db092c828e Don't pass by const-value for a read-only view.
I can't see a reason we pass by const-value here.

Note: changes API because of the `route_parameters` header.

b15f8f68e4 refactor and improve the round trip computation of multiple SCCs
Problem:
- old solution was slow
- depending on the result of TarjanSCC, new distance tables and new phantom node vectors were created to run tsp on it

Solution:
- dont create new distance tables and phantom node vectors
- pass an additional vector with the information which locations are in the same component and ignore all others

fix bug for scc split computation

62b20769ee Modernize the code base to C++11 standards and beyond.
Apply `clang-modernize` (based on Clang 3.6) transformations to the
codebase while making sure to support Clang>=3.4 and GCC>=4.8.

We apply the transformations in parallel to speed up the quite
time consuming process, and use our `clang-format` style file
to automatically format the code respecting our coding conventions.

We use the following self-explanatory transformations:

* AddOverride
* LoopConvert
* PassByValue
* ReplaceAutoPtr
* UseAuto
* UseNullptr

This required a `compile_commands.json` compilation database, e.g.

    ccmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXPORT_COMPILE_COMMANDS=1

for CMake or check Bear for a Makefile based solution (or even Ninja).

    git ls-files -x '*.cpp|*.h' | \
      xargs -I{} -P $(nproc) clang-modernize -p build -final-syntax-check -format -style=file -summary -for-compilers=clang-3.4,gcc-4.8 -include . -exclude third_party {}

Boom!
