Phew, a lot of classes were affected by this. The rationale for the
changes are as follows:
- When a type X declares any constructor, the default constructor is
not declared, so there is no need for X() = delete there. In fact,
there is brutal difference between those two: deleted members
participate in overload resolution, but not-declared members do not!
- When a type X wants to be non-copyable (e.g. to be only movable, like
threads, unique_ptrs, and so on), you can either do it by inheriting
from boost::noncopyable (the old way), or better declare both (!) the
copy constructor _and_ the copy assignment operator as deleted:
X(X const&) = delete;
X& operator=(X const&) = delete;
We had tons of types with deleted copy constructors that were lacking
a corresponding deleted copy assignment operator, making them still
copyable and you wouldn't even notice (read: scary)!

Note: I know, I'm quoting Hinnant's extraordinary slides a lot, but
getting the sematic right here is so incredibly important.
And includes the optional header that was transitively included by the
spirit header before. Hopefully this will speed up compile times, as the
RouteParameters header is used in a lot of translation units.
`pow(2, 16)` is not `2 << 16` but rather `1 << 16`.
With this change we cut memory usage in half for the XORFastHash's two
tables. Adapts XORFastHashStorage, memory usage reduction by factor two.
- Throwing an assertion exception for proper stack unwinding, making
sure destructors are called
- On in Debug mode, in Release, enable via:
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_ASSERTIONS=ON
Current problem that I'm seeing is that some code is not catching
exceptions or worse silently swallowing them. Would like to check the
whole pipeline before merging this in.
Fixes issue #1864. Given the simple set-up:
a --> b --> c
^-----------|
This would translate into an edge based graph (ab) -> (bc),
(bc) -> (ca), (ca) -> (ab).
Starting at the end of the one-way street (ab) and going to
the beginning, the query has to find a self-loop within the
graph (ab) -> (bc) -> (ca) -> (ab), as both nodes map to the
same segment (ab).
Found with
```
daniel@x1c /t/o/i/util> for header in *.hpp
echo -n $header:
ag -iQ $header ../../ --noheading | wc -l

fixed_point_number.hpp:0
range_algorithms.hpp:0

```
Only two. Surprises me to be honest.
But we're cleaning up for quite a bit now.
When you mark free standing functions as `static inline` instead
of just `inline` they can not get merged across TUs and therefore
produce code bloat which is bad for the binaries size, the CPUs
instruction cache, and so on.

Note that non-fully specialized templates (i.e. with a kind of at
least `Template :: * -> *`) are `inline` by default.
"status" is now always:
- 200 if the request was successful
- 207 if the result is empty (no path found)
- 400 if the request is invalid
viaroute and trip now have a maximum of 500 and 100 locations
respectively. Override with the --max-viaroute-size and --max-trip-size
parameters.
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.
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!
