NodeJS API docs are out of sync with NodeJS C++ wrapper documentation
due to the doc build breaking back in #4043.
The commit fixes the Node dev dependencies such that `npm run docs`
works again and re-enables the check in CI.
- Fix typo in util function name for_each_indexed.
- Use the overloaded functions for_each_indexed and for_each_pair
with a container argument where possible to improve readability.
This is a workaround for discrepancy between MSVC 19.27 and 19.28
about static const member definition

We can not use C++17 inline variable as a workaround suggested
in the issue report linked above, because the sol2 does not
seem to compile in C++17 mode:
third_party/sol2/sol2/sol.hpp: error C2039: 'object_type': is not a member of...
* Add missing profile name to library extract test.
* Support both tzid and TZID properties on timezone geometry. Improve validation of timezone polygons.
* Missing tzid property wasn't a geojson validation issue, shouldn't have been tested there.
* Use filesystem glob to loop over all test executables so we don't miss any in the future.

A request to osrm-routed can be assigned to a thread which
is currently busy processing another request, even when there
are other threads/cores available. This unnecessarily delays
the response, and can make requests appear to hang when
awaiting CPU intensive requests to finish.
The issue looks like a bug in Boost.Asio multithreaded
networking stack.
osrm-routed server implementation is
heavily influenced by the HTTP server 3 example in the
Boost.Asio docs. By upgrading to Boost 1.70 and updating the
server connections to match the example provided in the 1.70
release, the problem is resolved.
The diff of the changes to the Boost.Asio stack are
vast, so it's difficult to identify the exact cause. However
the implementation change is to push the strand of execution
into the socket (and timer) objects, which suggests it could
fix the type of threading issue we are observing.
osrm-routed does not immediately clean up a keep-alive connection
when the client closes it. Instead it waits for five seconds
of inactivity before removing.
Given a setup with low file limits and clients opening and
closing a lot of keep-alive connections, it's possible for
osrm-routed to run out of file descriptors whilst it waits for
the clean-up to trigger.
Furthermore, this causes the connection acceptor loop to exit.
Even after the old connections are cleaned up, new ones
will not be created. Any new requests will block until the
server is restarted.
This commit improves the situation by:
- Immediately closing connections on error. This includes EOF errors
indicating that the client has closed the connection. This releases
resources early (including the open file) and doesn't wait for the
timer.
- Log when the acceptor loop exits. Whilst this means the behaviour
can still occur for reasons other than too many open files,
we will at least have visibility of the cause and can investigate further.
Duplicate restriction nodes in the edge-based-graph are currently
not in included in a mapping (.osrm.cnbg_to_ebg) from
node-based-graph edges to edge-based-graph nodes.
This mapping is used by the MLD partitioner to assign EBG nodes
to partitions.
The omission from the mapping means all restriction nodes are
included in a special 'invalid' partition. This special partition
will break the geolocation properties of the multi-level hierarchy.
The partition and its super levels will have a large number of
border nodes and very few internal paths between them.
Given the partitioner is the only consumer of the mapping, we fix
the issue by including the duplicate restriction nodes in the mapping,
so that they are correctly assigned to a partition.
This has measurable improvement on MLD routing.
For a country-sized routing network, the fix reduces routing and table
request computation time by ~2% and ~6% respectively.
Replace Travis for continuous integration with Github Actions.
The Github Actions pipeline is functionally equivalent, with
all the same build permutations supported.
Whilst the Github Actions offering is broadly equivalent to
Travis, a few changes have been made as part of the migration.
- The 'core' and 'optional' Travis stages have been consolidated
into one build matrix. This is due to the current inability in
Github Actions to share build steps between jobs, so this avoids
having to duplicate the steps.
Optional stage jobs will now run in parallel with core jobs,
but they still remain optional in the sense that they don't fail
the build.
- A number of existing Github Action plugins are used to replace
functionality provided by Travis or other tools:
Node setup, caching, Codecov, publishing release artifacts.
- Linux builds are updated to build on Ubuntu 18.04.
MacOS builds are updated to run on 10.15. Similar to the
Travis Xenial upgrade attempt, some changes are required due
to underlying platform and compiler upgrades. This means some
Node 10 toolchains will no longer be supported.
Whilst there is opportunity to upgrade some dependencies and
make the CI steps more idiomatic, I've left this for future changes
and just focussed on functional replication.
When using process memory, MLD cell metrics are loaded twice from
.osrm.cell_metrics - once when loading static data, and again when
loading updatable data. The former appears to be the mistake,
as .osrm.cell_metrics is only listed in `GetUpdatableFiles`.
Removes the breaking libosrm API change by adding the old interface to
the new. This does not introduce any new breaks.
The downside of this is that it allows for multiple ways to
return JSON responses.
Regardless of any copy elision on the returned pair value, the
duration and distance results are always copied.
Fix this by passing rvalue references to std::make_pair.
Currently OSRM only supports turn restrictions with a single via-node or one
via-way. OSM allows for multiple via-ways to represent longer and more
complex restrictions.
This PR extends the use of duplicate nodes for representng via-way turn
restrictions to also support multi via-way restrictions. Effectively, this
increases the edge-based graph size by the number of edges in multi via-way
restrictions. However, given the low number of these restrictions it
has little effect on total graph size.
In addition, we add a new step in the extraction phase that constructs
a restriction graph to support more complex relationships between restrictions,
such as nested restrictions and overlapping restrictions.
In situations where there is not a valid source or target phantom
node (e.g. when snapping to an edge with a zero weight), a
heap assertion will fail in the MLD alternative search code.
We fix this by checking for empty heaps before proceeding with
the search.
