The change clarifies the conditions for forcing routing steps and
simplifies the codebase to support it.
- Makes explicity the search runtime condition for forcing a routing
step. Namely, the node is a source of the forward and reverse searches,
and it's one of the pre-identified nodes that requires a step to
be forced.
- Consolidate the two lists of force nodes into one. Not only is there
no algorithmic value in separating the nodes by geometric direction,
the improvements to via-routes with u-turns mean atleast one of these
lists will be empty for any search.
- Rename 'force loop' to 'force step'. This moves the code away
from the original CH-specific language for checking for self-loops
in the case where this condition is met. MLD does not have loops.
Additional cucumber tests are added to cover the logic related to
negative search weights and forcing routing steps on via-route
paths.
* Remove include that breaks compilation for Boost v1.85.0
* Update CHANGELOG.md
* Fix typo
* Fix issues found by newer clang-tidy version
* Add include to boost filesystem to satisfy Windows compiler
Each leg of a via-route supporting u-turns does not need to consider
force-loops. Negative weight checks are sufficient to prevent
incorrect results when waypoints are on the same edge.
* Added approach on the opposite side of the road.
* Additional test and docs coverage for opposite approach

* Extract prerelease/build information from package semver
Currently we only extract the major.minor.patch identifiers from
the semver label stored in package.json.
This leads to version information in executables incorrectly
reporting a release version is running on prereleases and special builds.
This commit is a quickfix to extract this information and report it
in version strings.
CMake regex parsing is not sophisticated enough to handle the full semver
regex, so we might need to explore other CMake modules if we want to
strictly parse the label.
Unidirectional traffic signal segments are currently not compressed.
This means traffic signals which are not on turns can be missed and
not applied the correct penalty.
This commit changes this behaviour to correctly handle the graph
compression. Additional tests are added to ensure there is no
regression for other cases (turns, restrictions).

* Pin Conan revisions correctly
Conan dependencies are not pinned correctly. This means we're
pulling in a newer onetbb recipe that no longer has a shared
library option.
Following other examples of how to pin revisions with cmake
for conan v1, we correctly pin the expected revisions.
Longer term we should look into
- upgrading to conan v2
- defining the conan config separately from cmakelists.txt
- understanding the need for disabling onetbb shared library support
but for the purposes of reviving CI, this will be sufficient.
* Fix macos CI builds
This change adds support for disabling datasets, such that specific
files are not loaded into memory when running OSRM. This enables users
to not pay the memory cost for features they do not intend to use.
Initially, there are two options:
- ROUTE_GEOMETRY, for disabling overview, steps, annotations and waypoints.
- ROUTE_STEPS, for disabling steps only.
Attempts to query features for which the datasets are disabled will
lead to a DisabledDatasetException being returned.
Currently `npm test` runs the Cucumber suite with a matrix
configuration for selecting the algorithm (CH, MLD) and data loading
(shared-memory, mmap) options.
However, there is a third data loading option, 'load directly',
which is to directly load the datasets into the osrm-routed process memory.
The code paths for each data loading option are distinct:
Storage::Run + SharedMemoryAllocator
MMapMemoryAllocator
ProcessMemoryAllocator
This commit adds direct data loading as part of the Cucumber
configuration matrix.
This will ensure optional dataset support can be added without any
regressions.
* Ensure required file check in osrm-routed is correctly enforced.
The storage module had a stricter check. This keeps the IOConfig
check in sync.
* Correct HTTP docs to reflect summary output dependency on steps parameter.
There is no summary parameter.
* npm audit fix

This change takes the existing typedefs for weight, duration and
distance, and makes them proper types, using the existing Alias
functionality.
Primarily this is to prevent bugs where the metrics are switched,
but it also adds additional documentation. For example, it now
makes it clear (despite the naming of variables) that most of the
trip algorithm is running on the duration metric.
I've not made any changes to the casts performed between metrics
and numeric types, they now just more explicit.
Weight and duration penalties are flipped in the lambda function
that applies penalties from traffic signals.
Duration is in deciseconds, whilst weight is multipled by
10^weight_precision, with weight_precision being 1 by default.
Therefore, for default routability profile, the penalties end up
being the same, hence why no tests picked this up.
If distance weight is used however, it will incorrectly apply an
additional penalty to the weight, and not add the traffic signal
delay to the duration in the routing graph.
To confuse things further, in some API responses the values are
correct because they use geometry data instead, but it's still
possible that a sub-optimal route was selected.
However, given the distance weight is in meters, and the additional
penalty per traffic light would be 20, it's unlikely this would
have changed the routing results.
In any case, we correct the function to apply the arguments correctly.
In case we're not able to get access to the unscoped credentials.
Scoped packages are also the recommended approach for projects
managed by a team of developers.
Badly constructed OSM intersections can create OSRM intersection
views that have no valid turns.
The guidance code for segregated intersections tries to look
ahead to the second intersection to ensure lanes are announced
intuitively.
Currently, OSRM assumes there are always turns at the second
intersection that we should consider. This commit corrects
this assumption so that it can now handle badly constructed
OSM intersections with no turns.
Due to some rather complex logic that tries to calculate intersection
angles by looking further up the road, it's possible to return
an intersection view that is missing a u-turn - something which
is assumed to exist in later guidance calculations.
We apply a fix here by ensuring the u-turn is always included in
the returned view.
Currently OSRM parses traffic signal nodes without consideration
for the direction in which the signal applies. This can lead
to duplicated routing penalties, especially when a forward and backward
signal are in close proximity on a way.
This commit adds support for directed signals to the extraction and
graph creation. Signal penalties are only applied in the direction
specified by the OSM tag.
We add the assignment of traffic directions to the lua scripts,
maintaining backwards compatibility with the existing boolean
traffic states.
As part of the changes to the internal structures used for tracking
traffic signals during extraction, we stop serialising/deserialising
signals to the `.osrm` file. The traffic signals are only used by
`osrm-extract` so whilst this is a data format change, it will not
break any existing user processes.
Currently there is an edge-case in the turn restriction implementation,
such that routes can not be found if the target input location snaps
to a way used in a (multi) via restriction.
With the addition of snapping input locations to multiple ways, we
can now also snap to the "duplicate" edges created for the restriction graph,
thereby fixing the problem.
This is achieved by adding the duplicate restriction edges to the
geospatial search RTree.
This does open up the possibility of multiple paths representing exactly
the same route - one using the original edge as a source, the other
using the duplicate restriction graph edge as source. This is fine,
as both edges are represented by the same geometry, so will generate
the same result.
This PR improves routing results by adding support for snapping to
multiple ways at input locations.
This means all edges at the snapped location can act as source/target
candidates for routing search, ensuring we always find the best route,
and not the one dependent on the edge selected.
There is a bug in the deflate compression. Therefore, we do not want
to select this in the default choice for HTTP response compression.
Instead we revert back to the previous precedence, selecting gzip as
the priority.
This change unblocks the osrm-extract debug build, which is
currently failing on a maneuver override assertion.
The processing of maneuver overrides currently has three issues
- It assumes the via node(s) can't be compressed (the failing assertion)
- It can't handle via-paths containing incompressible nodes
- It doesn't interop with turn restriction on the same path
Turn restrictions and maneuver overrides both use the same
from-via-to path representation.
Therefore, we can fix these issues by consolidating their
structures and reusing the path representation for
turn restrictions, which already is robust to the above
issues.
This also simplifies some of the codebase by removing maneuver
override specific path processing.
There are ~100 maneuver overrides in the OSM database, so the
impact on processing and routing will be minimal.
Currently route results are annotated with additional path information,
such as geometries, turn-by-turn steps and other metadata.
These annotations are generated if they are not requested or returned
in the response.
Datasets needed to generate these annotations are loaded and available
to the OSRM process even when unused.
This commit is a first step towards making the loading of these datasets
optional. We refactor the code so that route annotations are only
generated if explicitly requested and needed in the response.
Specifically, we change the following annotations to be lazily generated:
- Turn-by-turn steps
- Route Overview geometry
- Route segment metadata
For example. a /route/v1 request with
steps=false&overview=false&annotations=false
would no longer call the following data facade methods:
- GetOSMNodeIDOfNode
- GetTurnInstructionForEdgeID
- GetNameIndex
- GetNameForID
- GetRefForID
- GetTurnInstructionForEdgeID
- GetClassData
- IsLeftHandDriving
- GetTravelMode
- IsSegregated
- PreTurnBearing
- PostTurnBearing
- HasLaneData
- GetLaneData
- GetEntryClass
Requests that include segment metadata and/or overview geometry
but not turn-by-turn instructions will also benefit from this,
although there is some interdependency with the step instructions
- a call to GetTurnInstructionForEdgeID is still required.
Requests for OSM annotations will understandably still need to
call GetOSMNodeIDOfNode.
Making these changes unlocks the optional loading of data contained in
the following OSRM files:
- osrm.names
- osrm.icd
- osrm.nbg_nodes (partial)
- osrm.ebg_nodes (partial)
- osrm.edges
The internal representation of turn restrictions expects only one
`from` way and only one `to` way.
`no_entry` and `no_exit` turn restrictions can have multiple `from` and
`to` ways respectively. This means they are not fully supported by
OSRM's restriction parser.
We complete support for these turn restriction types by parsing all
ways and converting a valid restriction with multiple `from`/`to` members
into multiple internal restrictions.
Currently /trip supports finding round-trip routes where only the
start or end location is fixed. This PR extends this feature to
non-round-trip requests.
We do this by a new table manipulation that simulates non-round-trip
fixed endpoint requests as a round-trip request.
The data facade interface contains numerous methods for looking up
datapoints by identifiers.
Many of the parameters use the NodeID or EdgeID types. However, these two
identifier types are used for representing three different contexts:
1. Node-based graph edges and nodes
2. Edge-based graph edges and nodes
3. Packed geometries
Consider the use of identifier parameters in these examples:
---
GetWeightPenaltyForEdgeID(const EdgeID id) <- edge-based edge
GetUncompressedForwardWeights(const EdgeID id) <- packed geometry
IsLeftHandDriving(const NodeID id) <- edge-based node
GetBearingClass(const NodeID node) <- node-based node
---
This mixing of contexts within the same interface makes it
difficult to understand the relationships and dependencies between
the OSRM datasets.
For 1. and 2. we continue to use the NodeID and EdgeID types, but
change the interface parameter names to identify them as
edge-based or node-based graph properties.
For 3. we define a new type definition, PackedGeometryID.
These changes are to aid with readability. A next step would be
to strongly type these definitions, leveraging the Alias template
already used for OSM identifiers.
It is quite difficult to maintain current Windows CI, because it uses pre-compiled dependencies stored on wolt.com server and there is low chance to find someone who is able to update it.
* Remove highway=bicycle safety bonus
This removes a bonus for a road class that doesn't exist (cycleway would
be correct), but the code was buggy since safety_bonus is nil and caused
an arithmetic exception. We only caught this 4 (!) years later since
recently a way was tagged with highway=bicycle and made it in our OSM
data leading to preprocessing failures.
NodeJS API docs are out of sync with NodeJS C++ wrapper documentation

A recent change to the Ubuntu Focal CI worker - either a CMake upgrade,
or default installation of the libexpat-dev library - leads to the
32-bit expat library to not be found by CMake.
FindPackage(EXPAT) finds the library via pkg-config, so the fix is
to explicitly include the i386 pkg-config directory in the
PKG_CONFIG_PATH environment variable list.
During the CI migration to Github Actions, a bug was introduced
such that Mason CMake is not being added to the PATH environment
variable correctly, so it defaults to the CMake installed in the
OS environment.
Simple fixing the typo fails as the Mason CMake version requires
libssl 1.0 as a dependency, whilst the Ubuntu Focal runners are
on the newer libssl 1.1. Therefore, we also bump the Mason
CMake version to 3.21.2.

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.
* Fix test cache to consider MLD executable changes
Currently the test cache is not invalidated if changes to
osrm-partition or osrm-customize executables. This is problematic
when these executables make breaking changes to the data format.
We fix this by including both in the list of executables that
can invalidate the test cache.
* Executables use hyphens
Each MLD cell has source and destination nodes.
MLD is keeping a |source| x |destination| sized table
for various metrics (distances, durations, etc) from each
source to all destinations in a cell.
It stores all of the values for a metric in one large array, with
an offset for each cell to find its values. The offset is currently
limited to 32 bit values, which overflows on very large graphs
(e.g. Planet OSM).
We fix this by changing the offsets to be uint64_t types.
The generation of level masks for compactly storing partition cells
supports sizes that can be stored in 64 bits.
The current implementation fails if the total bit sum is 64 bits
exactly. A bit shift mechanism is used that is undefined when the
shift size is equal to the bit size of the underlying type. This
generates an incorrect mask value.
We fix this by adding a special case for a 64 bit offset. Given this
code is called at most |level| times, there will be no effect on
performance. We also update the assertions to reflect 64 bit masks
are now supported.
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.
In newer versions of cmake, FindBoost uses Imported Targets for library
component variables, rather than file paths to the Boost libraries.
cmake uses these targets when linking (e.g. target_link_library) and
knows how to correctly substitute the values. However, the OSRM
pkg-config file that we generate doesn't do this, and ends up writing
the actual target symbols, hence the errors trying to link Boost::<component>.
To fix this for newer cmake versions, we create an intermediate configure step
that references the linker files for the imported targets. This is followed
by a generate step that performs the correct substitution.
See this thread for more details: https://cmake.org/pipermail/cmake/2018-December/068812.html
This is backwards compatible to the existing min cmake version (3.1).
However, building using cmake 3.1 fails with a package.json parsing error,
so this commit also bumps the min version to 3.2.
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.
* Handle maxspeed tags before surface and smoothness tags
Let's say we have a tertiary road with the following tags:
highway=tertiary
maxspeed=60
surface=gravel
smoothness=intermediate
While the maxspeed tag tells us the legal speed limit, the surface and
smoothness tags have much more effect on the real-world speed of a car.
We should process the maxspeed tags first, and then update the road's
forwards/backwards speeds according to any surface and smoothness tags.
For our hypothetical road the process in the car.lua profile now goes
like this:
1. Get default speed from profile (tertiary = 40 on line 150 of car.lua)
2. Change speed to 60 using maxspeed tag (WayHandlers.maxspeed function
in way_handlers.lua, lines 434-447)
3. Change speed to 40 using surface tag (WayHandlers.surface function
in way_handlers.lua, lines 360-363)
4. Check speed according to smoothness tag --- but because it's higher
than the speed according to the surface tag, leave the speed
unchanged (WayHandlers.surface function again, lines 368-371)
<ec36319232/profiles/car.lua (L150)>
<ec36319232/profiles/lib/way_handlers.lua (L354-L372)>
Note in step 3 above the speed's only changed from 60kph to 40kph
because it's a lower value. If the surface speed was higher than than
the previous value, the speed would remain unchanged. Another example:
highway=tertiary
maxspeed=60
surface=compacted
smoothness=intermediate
Here, although the profile's speed for compacted is 80, it would stay at
the lower value of 60 (see way_handlers.lua, lines 360-363).
<ec36319232/profiles/lib/way_handlers.lua (L360-L363)>
* Use Github Releases for hosting node binaries
Replaces S3 hosting of node binaries with Github Releases.
`node-pre-gyp publish` works exclusively with S3, so upload step
is now performed by the Travis deployment provider.
The behaviour for the package user should not change.
When building a new version tag, Travis will create a release for the
tag if it does not already exist.
* Switch to the osrm-release-automation machine account rather than personal credentials.

OSM node 2^33 was created in early April 2021. This and all
subsequently created IDs will be overflowing OSRM node storage
which only support 33 bit IDs.
Bump the number of bits to 34 to double node ID capacity. This
is a breaking change to the data format as it alters the layout
of .osrm.nbg_nodes.
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`.
OSM data contains many mistakes that tag kerbs as highway barriers
when instead they are only describing highway crossings.
This PR updates the default car profile to handle these mistakes
and unblock routing on the affected highways.
Bundling node-pre-gyp was only needed for node v4 and earlier.
Remove it to avoid errors like:
> npm ERR! enoent ENOENT: no such file or directory, rename '/home/circleci/project/node_modules/node_or_tools/node_modules/abbrev' -> '/home/circleci/project/node_modules/node_or_tools/node_modules/.abbrev.DELETE'
More context: https://github.com/mapbox/node-pre-gyp/issues/260#issuecomment-407222286
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.
When using non-default constructors for the API parameter classes,
vector arguments like coordinates and hints are copied at least once
(twice when passed as lvalue arguments).
Enable perfect forwarding of BaseParameter arguments and
pass-by-value in the constructor that uses the argument. This
ensures we copy at most once (zero for rvalue arguments).
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.

As part of graph contraction, node renumbering leads to
in-place permuting of graph state, including boolean vector elements.
std::vector<bool> returns proxy objects when referencing individual
bits. To correctly swap bool elements using MSVC, we need to explicitly
apply std::vector<bool>::swap.
Making this change fixes osrm-contract on Windows.
We also correct failing tests and other undefined behaviours
(mainly iterator access outside boundaries) highlighted by MSVC.
For very large graphs, generation of MLD level masks fail on Windows
due to bit shift overflow of unsigned long values.
Correct by using unsigned long long literals, which are 64 bit on
all major systems.
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.
Fixes#5788
Table queries where source and destination are phantom nodes
on the same one-way segment can fail to find valid routes.
This is due to a bug in the MLD table generation for the
special case where the query can be simplified to a
one-to-many search.
If the destination is before the source on the one-way segment,
it will fail to find a route.
We fix this case by not marking the node as visited at the start,
so that valid paths to this node can be found later in the search.
We also remove redundant initialization for the source
node as the same actions are performed by a search step.
In cases where we are unable to find a phantom node for an input
coordinate, we return an error indicating which coordinate failed.
This would always refer to the coordinate with index equal to the
number of valid phantom nodes found.
We fix this by instead returning the first index for which a
phantom node could not be found.
Replaces references to
`include/extractor/guidance/road_classification.hpp` with
`include/extractor/road_classification.hpp`.
The latter is included in the project.
The query if(WIN32 AND CMAKE_BUILD_TYPE MATCHES Debug) only works if you call CMake explicitly with the build configuration Debug. But if you generate Debug and Release all libraries are linked to the release version.
In Lua 5.4 the function lua_resume now has an extra parameter. This out parameter returns the number of values on the top of the stack that were yielded or returned by the coroutine (in previous versions, those values were the entire stack.). The constant LUA_ERRGCMM was removed. Errors in finalizers are never propagated; instead, they generate a warning.
After run `lua5.1 profiles/debug_example.lua`, I got result:
```
lua5.1: debug_example.lua:41: attempt to call field 'way_function' (a nil value)
stack traceback:
debug_example.lua:41: in main chunk
[C]: ?
```
This is because Debug has not way_function in the module. This changes
change it to process_way and it's works!!
In the case of a shared object compilation, the resulting binaries need
that library. It was not installed along the others, leading to failures
when running osrm-extract.
Fixes#5603
It actually makes no sence, as the only output on the 'Nearest' service
is a list of wypoints. On the other hand it can be used now as a simple
health check.
* Replaced Response union with nullable fields
* "Ok" code replaced with a boolean and a separate structure for a error code and message.
* Inlined geometry, thus removing one layer of indirection.
Same as for Route service, you can now specify either json or flatbuffers
as output format for the other services (except Tile service, where it
makes no sense).

Upgrades the build environment to Node 10, which let's us pull down some security fixes in package dependencies that were unfixed in Node 4.
Also removes Node 4 and 6 binary publishing which were almost never used (20 downloads out of 50,000).
Fixes https://github.com/Project-OSRM/osrm-backend/issues/5312
Includes all edges in the rtree, but adds an `is_startpoint` flag to each. Most plugin behaviour remains unchanged (non-startpoint edges aren't used as snapping candidates), but for map matching, we allow snapping to any edge. This fixes map-matching across previously non-is_startpoint edges, like ferries, private service roads, and a few others.

As I mentioned in the issue #5156, I met below issue on my Win10+WSL(Ubuntu) env:
The remote debugger (VSCode on Win10, gdb on Ubuntu 18.04 LTS) works well from the beginning of the main() function. But when I step over the code pthread_sigmask(SIG_BLOCK, &new_mask, &old_mask); (src/tools/routed.cpp(289)), below breakpoints can not work and displayed unverified breakpoint.
Then I found that gdb breakpoint need at least SIGTRAP, SIGSTOP to work (Please refer to [how debugger works](http://www.alexonlinux.com/how-debugger-works) for more details), but all signals are blocked in the source code until server initialized done.
In my understanding, block all signals DO NOT make sense for this osrm-routed process. Only several signals (SIGINT, SIGQUIT, SIGTERM) are expected to wait. So I made the change and it works well for me then.
* fix incorrect parameter parsing for node osrm and add tests
* fix boost spirit grammar parsing for annotations
* return NotImplemented when distance annotation is requested for MLD in table plugin
* update docs

and non-boundary nodes. Since there are only we boundary nodes we can
use the ArrayStorage for those yielding much faster query times.

Some compilers (eg. MSVC) still require inclusion of <ciso646>

It is easier to stick with traditional punctuators.
Make entry points of individual pipeline stages responsible for
configuring the task scheduler with requested number of threads
passed in corresponding configuration bundle (ie. follow extractor).
Rename module partition to partitioner.
This cultivates naming used in existing modules like extractor,
customizer, etc. - noun vs verb (word partition is both though).

As a form of smoothing we use the previous speed value instead.
This makes sense because the zero duration segments have to be very
short, potentially also zero length.
Pool instance has been removed from Reader ctor parameters
list in PR #4438, presumably unintentionally.
It is required to prevent potential deadlock during
Pool shutdown as explained in PR #4452.

When doing the new Lua version refactor we changed the expectation to
use `continue uturn` instead of making a whole circle in the roundabout
as the original test case. This was only the shortest path since there
was no roundabout penalty.
- separates node-based graph creation and compression from edge-based graph creation
- moves usage of edge-based node data-container to pre-processing as well, unifying access to node-based data
- single struct instead of separate vectors for annotation data in engine (single place of modification)
There is no possibility until multiple-weights are implemented
to break tie in the contraction and the direct shortest path plugin
as duration is not computed during contraction.
This must be fixed after multiple-weights implementation
by using `std::tie(weight, duration)` pairs everywhere.
Advantages:
* Allows to use Pool configured with user-preferred number of threads.
* If libosmium used in a shared library, this helps to prevent potential
deadlock during Pool shutdown at (after) shared library unloading.
See https://github.com/osmcode/libosmium/pull/214
Requires libosmium 2.13.0
Default-constructed objects of (boost::heap) handle_type are singular,
including the wrapped handle_type::iterator.
Apparently, MSVC iterator debug facilities strictly require that
one singular instance is compared to another singular instance.
It is not possible to get check-comparabe iterators of non-singular
and singular instances as owning container will always mismatch.
This reverts commit 4686272f87.
Unfortunately, this doesn't work alongside `node-pre-gyp` - in fresh installs, the binary

- refactor conditional restriction handling to not use external data (first OSM nodes on ways)
- BREAKING: changes internal file format of osrm.restrictions

Unify CMAKE_CXX_COMPILER_ID tests without quoting/bracketing
the variable to use implicit expansion.
Replace STREQUAL with MATCHES to avoid policy warning about
attempt to expand "MSVC" variable, where it literal is intended.
If Visual C++ _ITERATOR_DEBUG_LEVEL > 0, then
accessing std::array<char[N], M> elements via reference to const
causes compilation error:
...\msvc\14.10.25017\include\array(181): error C2440: 'return': cannot convert from 'const char *' to 'const char (&)[256]'
Alternative workaround is to remove const qualifier from the GetClassName method.
Makes turn restrictions into dedicated structures and diferentiates between them via a variant.
Ensures that we do not accidentally mess up ID types within our application.
In addition this improves the restriction performance by only parsing all edges
once at the cost of (at the time of writing) 22MB in terms of main memory usage.
The viaroute plugin always expects a route to be there potentially
with invalid edge weight to represent no-route-found. By switching
to the many-route-result for the mld alternatives algorithm we might
return an empty many-route-result invalidating the post-condition.

The alpha constant is for the local optimality T-Test threshold.
Before we used epsilon for the T-Test threshold, but the epsilon
constant is meant to be used for the stretch test(s) only.
This changeset fixes the local optimality T-Test and uses the
epsilon constant for the two stretch tests:
- We test the stretch for the total route against epsilon and
- We test the detour against the epsilon now, too
We can discuss if the second stretch test should actually use
epsilon, too, or a adapted value of it - but definitly not alpha.
The new numbering uses the partition information
to sort border nodes first to compactify storages
that need access indexed by border node ID.
We also get an optimized cache performance for free
sincr we can also recursively sort the nodes by cell ID.

(i.e. stuff that's stored in our datafiles). Keep those checks for user-supplied values
(i.e. coordinates coming from files during preprocessing, or coordinates supplied by users
during requests)
This fixes issues #3952. The new approach pre-computes masks for fast
access. Since elements can potentially span multiple words we need masks
and offsets for each upper and lower word.
Due to a bug in the C++14 standart the mask computation is not
recognized as constexpr, but would work on C++17.

if in_forward_direction is also true backward segments can be incorrectly duplicated
Recent improvements to OSRM have led to a lot of changes to the Lua scripting interface, and refactoring of the default profiles makes them slightly more abstract and difficult to grok for those writing profiles from scratch.
This is therefore an attempt to fully document the attributes that can be read and set from Lua profiles. I've done it from my own understanding and from reading the source, but I may well have missed things or mistaken them!
The Map Matching plugin currently has issues with:
- high frequency traces and (performance)
- blobs, think noise at traffic signals (correctness)
This changeset implements trace-tidying transparently for the user.
We hopefully will see both performance gains as well as better matches!
This graph enables efficient boundary edge scans at each level.
Currenly this needs about |V|*|L| bytes of storage.
We can optimize this when the highest boundary nodes ID is << |V|.
Leaving log files opened was intentional to avoid missing output
that can appear `child.on('exit',...)`.
With this approach cucumber tests hit locally maximum number
of opened files, because node.js keeps all log files opened.
This commit removes all occurences of unconnected boundary nodes
and switches to the simple heuristic of picking U for the forward
and V for the backward node. This performs better than several
fancy heuristics.
By default, ExtractorConfig::requested_num_threads is Zero,
which is an invalid value for tbb task scheduler.
If user does not specify value greater than Zero, then
use tbb::task_scheduler_init::automatic.
Here's all I could get out of a instrumented `osrm-partition`; debug build,
with all the bells and whistles I could think of to make it more verbose:
```

Looks like a crt finalizer => static global dtor "leaking" from tbb.
Which turned out to be a missing `tbb::task_scheduler_init` on our end:
> Using task_scheduler_init is optional in Intel® Threading Building
> Blocks (Intel® TBB) 2.2. By default, Intel TBB 2.2 automatically creates

https://www.threadingbuildingblocks.org/docs/help/hh_goto.htm?index.htm#reference/task_scheduler/task_scheduler_init_cls.html
Without an explicit instanz the first call to a tbb algorithm seem to initialize
a global scheduler singleton which then "leaks" until the program exits.
Phew.

If originalEdges gets initialized with 1 << 28, it will overflow and
thereby be set to 0.
Which defeats the point of checking for overflows in the first place.
LLVM 3.9.1 is now packaged in mason: https://github.com/mapbox/mason/issues/308
Upgrade our Clang compiler to the latest stable release.
Keeps clang-format at 3.8.1 for consistency.
This disables the `-flto` LTO flag by default since we're seeing
segfaults in compiler lto plugins, binutils and linker errors again and
again for various clang / gcc / binutils combinations.
Pass `-DNEBALE_LTO` to `cmake` in order to re-enable LTO.
LTO situation in short:
- LTO does not work at all for gcc<4.9
- With gcc>=4.9 the "slim" LTO format is getting used dumping IR
- Older binutils need LTO plugins which know how to read this IR
- Recent binutils handle this format all by themselves
- LLVM is more or less the same with some Clang versions segfaulting
If you need the performance benefit of LTO, make sure your compiler and
binutils are up to date and see for yourself if LTO builds work for you.

Lane Anticipation currently triggers on quick steps with lanes. This
changeset makes the "quick" part more dynamic by taking lanes left and
right of the turn into account. The reasoning for this is as follows.
The user can drive on the leftmost or rightmost lane and has to cross
all lanes left or right of the turn, respecitvely.
We scale our threshold appropriately, which now means the threshold
describes the duration the user needs for crossing _a single lane_.
Note: this is a heuristic and assumes the worst case. Which in my
opinion is fine to do since triggering Lane Anticipation in complex
scenarios is desirable.
This keep the metadata reader flag disabled by default unless explicitly specified.

Adds an `generate_hints=false` option which lets us skip generating and

size when the user does not need hints anyway.
We should think about making `false` the default here in v6.
This change fixes two bugs:
1. A dead-lock that occurs between osrm-datastore and libosrm when an
old dataset is free during a data update. This happened because the
mutexes where acquired in a different order.
2. A region is deleted eventhough it is still in use. This happens when
libosrm gets overtaken by osrm-datastore, so the new dataset is in
the same region the old one was.
instead of artificially removing lanes from a roundabout, we don't assing them in the first place.
this also prevents a problem where we would end up collapsing turns with lanes in a roundabout
These kind of roundabouts came up during Lane Handling for roundabouts.
They're called Turbo-roundabouts or Turbine-roundabouts and are very
popular e.g. in Germany and the UK.
Seems like our roundabout handler sometimes is getting confused.
Trying to figure out why, and codifying some scenarios for cucumber.

removes duplicated includes

moves functionality close to data, where possible
Usage:
struct MyIntersection : EnableIntersectionOps<MyIntersection> {

Done.
We require MyIntersection having at least the member attributes from
IntersectionViewData but don't enforce a inheritance hierarchy.
Changes the processing order in the edge based graph factory.
Instead of iterating over all outgoing edges in order, we compute the edge
expanded graph in the order of intersections.
This allows to remember intersection shapes and re-use them for all possible ingoing edges.
Also: use low accuracry mode for intersections degree 2 intersections
We can use lower accuracy here, since the `bearing`
after the turn is not as relevant for off-route detection.
Getting lost is near impossible here.

# This is the 3rd commit message:

use clang++ 3.8.1 for mason builds since 3.8 is what we have been using
- Travis: Upgrade clang from 3.8.0 to 3.8.1 (provides smaller package for faster downloading)
- Travis: Makes BUILD_COMPONENTS an option
- Followup after #3130 (Boost_LIBRARIES variable no longer exists)
From stxxl FAQ: "you should not share a data structure between
threads (without implementing proper locking yourself)."
The access to name_char_data can be implicitly parallelized
if _GLIBCXX_PARALLEL is defined and invalidate local-thread iterators.
- Builds up ENGINE_LIBRARY_LISTING correctly to pass to pkg-config
- Previous behavior had major flaw and would result in paths in libosrm.pc like: "-L-L"
when the data was "-L/path -lfoo" or just "-lpthread" with no -L/path. It only worked correctly for static libraries
- Refactors to call find_package for boost in one place (helps prepare for upcoming mason PR)
Removes CompressedEdges from the extractor and shared data format by
directly serializing vectors of node ID's, forward weights and reverse
weights for each node-based-edge
Refs #2575
This PR adds more advanced coordinate extraction, analysing the road
to detect offsets due to OSM way modelling.
In addition it improves the handling of bearings. Right now OSM reports
bearings simply based on the very first coordinate along a way.
With this PR, we store the bearings for a turn correctly, making the
bearings for turns correct.
* cucumber test scenarios, #3027
* post review comments
* two tests are still failing
* fixed one test
* passing tests
* cleaner code refactor
* possible sceanrios for destination:ref:forward/backward
* added code for direction:ref:forward/backward, tests pass
* changelog
* store direction in variable
* added tags to taginfo
* fixed dumb error
* use boolean flags
* null pointer checks
* hopefully better null pointer checks
This switchtes the data even if there are requests still running on the
old data. osrm-datastore then waits until all of these old requests have
finished before freeing the old regions.
This also means that osrm-datastore will return with an error if there
is a data update currenlty in progress.
Changes the internal representation of compressed geometries to be a
single array shared between forward and reverse geometries that can be
read in either direction. Includes a change on
extractor::OriginalEdgeData to store via_geometry ids that indicate
which direction to read the geometry for that edge based edge.
Closes#2592
Technically speaking we're changing the `libosrm` API.

we should be fine here.

Takes a stricter aproach for whitelisting / blacklisting restrictions:
- uses `restriction=`
- uses more specific `restriction:<type>=`
- uses `except=<type>` to invert
Where `type` is the type of transportation to restrict, e.g. `motorcar`.
https://github.com/Project-OSRM/osrm-backend/issues/2833
With @karenzshea's name / ref split (ref. #2857) in master we want to
make use of it and reduce `NewName` instructions when ever possible.
This is a first step towards #2744 by using the already existing name
change heuristic from the extractor now in post-processing as well.
Limitations: at the moment we don't have the `SuffixTable` in
post-processing; this would require us serializing and subsequently
deserializing the table, passing it through from the profiles to the
API.
Before we only worked on subsequent quick turns, as in:
`right, right` keeps the user on the rightmost lanes.
This changeset modifies the logic to work on any subsequent steps
that are "quick" and have lane information we can constrain later.
Because we do not have a from-lane => to-lanes mapping we take the
lanes left and right of the turn lanes into account when heuristically
assigning the leftmost / rightmost lanes.
There are some edge cases where this still does not give us the optimal
solution but it gets close to what is actually possible at the moment
without having a lane mapping in post-processing.

fix rebase
Issue 2785: check gold binutils version and don't use gc-sections for versions prior 2.25
due to https://sourceware.org/bugzilla/show_bug.cgi?id=17639
readelf --debug-dump=frames build/libosrm_extract.so
Contents of the .eh_frame section:
...
readelf: Warning: Invalid length 0xfff01dd8 in FDE at 0x000020
Currently we don't route over the Golden Gate bridge by default.
This sets the value to false by default. To test the behavior for
tolls when ignored, we would need issue #2781 implemented.
Roundabout Intersections are roundabouts with up to four ways and turn
angles which makes the turns obvious, e.g. as in:
```
*
*
* * * *
*
*
```
but not
```
*
*
* * *
* *
* *
```
For Roundabout Intersections we issue instructions such as
"turn <direction>" instead of "take the <nth> exit".
At the moment we have a limit on the radius for these Roundabout
Intersections of 5 meters. Which fails to classify a wide range of
Roundabout Intersections in the US (with the US-wide streets).
This changeset removes the Roundabout Intersection radius limit:
- if the roundabout is larger than a threshold and is named we classify
it as a rotary
- if the roundabout matches our criteria for Roundabout Intersections
we classify it as a Roundabout Intersection
- else fallback to plain old Roundabout
There is a second issue with determining a roundabout's radius.
But that's for another pull request (tracking in #2716).

Staggered intersection are very short zig-zags of only a few meters.
They are common in rural and exurban areas, especially in the US.
(In addition, these cases could as well be tagging issues)
We do not want to announce these short left-rights or right-lefts:
* -> b a -> *
| or | becomes a -> b
a -> * * -> b
Here is one example:
- https://www.openstreetmap.org/edit#map=20/39.26017/-84.25182
And here are two edge-cases that we don't handle at the moment:
- http://www.openstreetmap.org/edit#map=20/38.87900/-76.98519
- http://www.openstreetmap.org/edit#map=19/45.51056/-122.63462
and probably should not handle since the distance in between is
quite long (roughly 7-15 meters). For these we want to announce
two turns to not confuse the user.
Thanks to @1ec5 for raising this issue and @karenzshea for
providing additional US examples and cultural insights.

__attribute__((warn_unused_result))
```
This changeset does exactly that: for the new guidance code prone to
these kind of issue we add such an attribute to the declaration.
Why only `hov=designated` and not all access tags, such as `hov:yes`,
`hov=no` and so on? From the Wiki:
- designated: The way is designated to high occupancy vehicles.
- yes: High occupancy vehicles are allowed. This by itself does not imply that other vehicles are restricted from using the way.
- no: High occupancy vehicles are not allowed on the way. This by itself does not imply that other vehicle types are allowed to use it.
The primary use-case is conditionally filtering ways such as:
http://www.openstreetmap.org/way/11198593#map=19/37.82571/-122.30521&layers=D
In addition there is a notion of HOV lanes for lane handling:
http://wiki.openstreetmap.org/wiki/Key:hov#hov:lanes.3D.2A
This changeset does not handle lanes at all, only designated HOV ways.
For HOV lane support, a logic similar to the lane access handling needs
to be implemented. This needs to go hand in hand with the existing lane
handling introduced in:

After half a day of looking at the tagging and the data came to the
following conclusion:
We can't keep the user to the innermost / outermost lanes depending on
the exit the route takes: we found situations where both heuristics were
wrong.
Even on popular roundabouts the tagging is often wrong or in the best
case not present at all.
There are at least two different ways to interpret roundabout
indications: 1/ where e.g. a right arrow on the lane indicates turn
restrictions for the roundabout and the need to take this lane to exit
the roundabout to the right (possibly skipping multiple exits) and 2/
where a right arrow just means this is a lane in a immediate right turn.
Example: Australia marks lanes with arrows that seem to indicate
"angles you can exit the roundabout from", for example, these two ways:
- http://www.openstreetmap.org/way/320941710
- http://www.openstreetmap.org/way/42918021
Whereas Germany marks lanes with "directions you can travel in these
lanes immediately after entering the roundabout":
- http://www.openstreetmap.org/way/52578338
These two different interpretations of how to draw the arrows on the
roads mean we have conflicting solutions to "which lanes can you use to
take exit B from entry A" based on locality.
Continuing to tag ways based on lane markings is no problem, but
unfortunately, we can't reliably resolve good advice for navigation
system users (like "use the inside lane to take the second exit at the
roundabout"), there are too many situations that would generate bad
instructions (instructions that tell users to go into a lane they
shouldn't use).
Before we asserted on unique lane indications per lane. Turns out the
OSM data contains lane strings such as:
left;left|right
Which represents two lanes as in:
<< >
|| |
The two left indications _on a single lane_ look like data issue.
And we can't represent this with our enum-approach at the moment.
We don't want to crash there, so silently swallow this and
generate a single left|right for it.
This changeset implements Lane Anticipation on roundabouts, delimited
by enter / leave step pairs. It does not handle lane anticipation
within a roundabout.
Lane anticipation happens on the granularity of a valid roundbaout:
We discard partial roundabout (enter without exit or exit without
enter) or data issues (no roundabout, exit before enter).

going straight in lane anticipation
We build `osrm_contract` (the library) linking in libtbb. We then
build `osrm-contract` (the binary) linking in `osrm_contract` (the
library).
Because we're only using TBB's `parallel_invoke` in the code for the
binary, it seems like the linker discards some symbols in the library.
Therefore we have to link libtbb for the binary again. Even worse, the
order now matters: if we first link in `osrm_contract` and then libtbb,
we're still hitting the issue re. discarded symbols.
Therefore we first link in all dependencies (libtbb, libboost*), and
only then `osrm_contract`.
Strictly speaking, we probably have to do this for all of our binary
targets, or we will hit similar issues in the future.

This is more of a hack but looks like the best we can do.
The reason for this is the following:
1/ we require strict mode for our v4 script
2/ v0.10 in strict mode marks 'let' as a reserved keyword,
aborting before execution any code in the script. Thus,
we can't assert e.g. on process.versions['node'] !== '4'.
Aligned blocks prevent bus errors in NEON/VFP instructions.
Block pointers are aligned to 4 bytes, that is guaranteed
by aligned mmaped-pointers, the 4 bytes size of the CANARY block and
aligned sizes of blocks.

- ADDED: Now publishing Node 8.x LTS binary modules
- Profile:
- CHANGED: Remove dependency on turn types and turn modifier in the process_turn function in the `car.lua` profile. Guidance instruction types are not used to influence turn penalty anymore so this will break backward compatibility between profile version 3 and 4.
- Guidance:
- ADDED: New internal flag on "segregated intersections" - in the future, will should allow collapsing of instructions across complex intersection geometry where humans only perceive a single maneuver
- CHANGED: Decrease roundabout turn radius threshold from 25m to 15m - adds some "exit the roundabout" instructions for moderately sized roundabouts that were being missed previously

- FIXED: undefined behaviour when alternative candidate via node is same as source node ([#4691](https://github.com/Project-OSRM/osrm-backend/issues/4691))
- FIXED: ensure libosrm.pc is pushed to the correct location for pkgconfig to find it on all platforms
- FIXED: don't consider empty names + empty refs as a valid name for u-turns
# 5.13.0
- Changes from 5.12:

- Append cardinal directions from route relations to ref fields to improve instructions; off by default see `profile.cardinal_directions`
- Support of `distance` weight in foot and bicycle profiles
- Support of relations processing
- Added `way:get_location_tag(key)` method to get location-dependent tags https://github.com/Project-OSRM/osrm-backend/wiki/Using-location-dependent-data-in-profiles
- Added `forward_ref` and `backward_ref` support
- Left-side driving mode is specified by a local Boolean flag `is_left_hand_driving` in `ExtractionWay` and `ExtractionTurn`
- Support literal values for maxspeeds in NO, PL and ZA
- Infrastructure:
- Lua 5.1 support is removed due to lack of support in sol2 https://github.com/ThePhD/sol2/issues/302
- Fixed pkg-config version of OSRM
- Removed `.osrm.core` file since CoreCH is deprecated now.
- Tools:
- Because of boost/program_options#32 with boost 1.65+ we needed to change the behavior of the following flags to not accept `={true|false}` anymore:
- The deprecated options `--use-level-cache` and `--generate-edge-lookup`
- Bugfixes:
- Fixed #4348: Some cases of sliproads pre-processing were broken
- Fixed #4331: Correctly compute left/right modifiers of forks in case the fork is curved.
- Fixed #4472: Correctly count the number of lanes using the delimter in `turn:lanes` tag.
- Fixed #4214: Multiple runs of `osrm-partition` lead to crash.
- Fixed #4348: Fix assorted problems around slip roads.
- Fixed #4420: A bug that would result in unnecessary instructions, due to problems in suffix/prefix detection
- Algorithm
- Deprecate CoreCH functionality. Usage of CoreCH specific options will fall back to using CH with core_factor of 1.0
- MLD uses a unidirectional Dijkstra for 1-to-N and N-to-1 matrices which yields speedup.
# 5.12.0
- Changes from 5.11:
- Guidance
- now announcing turning onto oneways at the end of a road (e.g. onto dual carriageways)
- Adds new instruction types at the exit of roundabouts and rotaries `exit roundabout` and `exit rotary`.
- HTTP:
- New query parameter for route/table/match/trip plugings:
`exclude=` that can be used to exclude certain classes (e.g. exclude=motorway, exclude=toll).
This is configurable in the profile.
- NodeJS:
- New query option `exclude` for the route/table/match/trip plugins. (e.g. `exclude: ["motorway", "toll"]`)
- Profile:
- New property for profile table: `excludable` that can be used to configure which classes are excludable at query time.
- New optional property for profile table: `classes` that allows you to specify which classes you expect to be used.
We recommend this for better error messages around classes, otherwise the possible class names are infered automatically.
- Traffic:
- If traffic data files contain an empty 4th column, they will update edge durations but not modify the edge weight. This is useful for
updating ETAs returned, without changing route selection (for example, in a distance-based profile with traffic data loaded).
- Infrastructure:
- New file `.osrm.cell_metrics` created by `osrm-customize`.
- Debug tiles:
- Added new properties `type` and `modifier` to `turns` layer, useful for viewing guidance calculated turn types on the map
# 5.11.0
- Changes from 5.10:
- Features
- BREAKING: Added support for conditional via-way restrictions. This features changes the file format of osrm.restrictions and requires re-extraction
- Internals
- BREAKING: Traffic signals will no longer be represented as turns internally. This requires re-processing of data but enables via-way turn restrictions across highway=traffic_signals
- Additional checks for empty segments when loading traffic data files
- Tunes the constants for turns in sharp curves just a tiny bit to circumvent a mix-up in fork directions at a specific intersection (https://github.com/Project-OSRM/osrm-backend/issues/4331)
- Infrastructure
- Refactor datafacade to make implementing additional DataFacades simpler
- Bugfixes
- API docs are now buildable again
- Suppress unnecessary extra turn instruction when exiting a motorway via a motorway_link onto a primary road (https://github.com/Project-OSRM/osrm-backend/issues/4348 scenario 4)
- Suppress unnecessary extra turn instruction when taking a tertiary_link road from a teritary onto a residential road (https://github.com/Project-OSRM/osrm-backend/issues/4348 scenario 2)
- Various MSVC++ build environment fixes
- Avoid a bug that crashes GCC6
- Re-include .npmignore to slim down published modules
- Fix a pre-processing bug where incorrect directions could be issued when two turns would have similar instructions and we tried to give them distinct values (https://github.com/Project-OSRM/osrm-backend/pull/4375)
- The entry bearing for correct the cardinality of a direction value (https://github.com/Project-OSRM/osrm-backend/pull/4353
- Change timezones in West Africa to the WAT zone so they're recognized on the Windows platform
# 5.10.0
- Changes from 5.9:
- Profiles:
- New version 2 profile API which cleans up a number of things and makes it easier to for profiles to include each other. Profiles using the old version 0 and 1 APIs are still supported.
- New required `setup()` function that must return a configuration hash. Storing configuration in globals is deprecated.
- Passes the config hash returned in `setup()` as an argument to `process_node/way/segment/turn`.
- Properties are now set in `.properties` in the config hash returend by setup().
- initialize raster sources in `setup()` instead of in a separate callback.
- Renames the `sources` helper to `raster`.
- Renames `way_functions` to `process_way` (same for node, segment and turn).
- Removes `get_restrictions()`. Instead set `.restrictions` in the config hash in `setup()`.
- Removes `get_name_suffix_list()`. Instead set `.suffix_list` in the config hash in `setup()`.
- Renames `Handlers` to `WayHandlers`.
- Pass functions instead of strings to `WayHandlers.run()`, so it's possible to mix in your own functions.
- Reorders arguments to `WayHandlers` functions to match `process_way()`.
- Profiles must return a hash of profile functions. This makes it easier for profiles to include each other.
- Guidance: add support for throughabouts
- Bugfixes
- Properly save/retrieve datasource annotations for road segments ([#4346](https://github.com/Project-OSRM/osrm-backend/issues/4346)
- Fix conditional restriction grammer parsing so it works for single-day-of-week restrictions ([#4357](https://github.com/Project-OSRM/osrm-backend/pull/4357))
- Algorithm
- BREAKING: the file format requires re-processing due to the changes on via-ways
- Added support for via-way restrictions
# 5.9.2
- API:
- `annotations=durations,weights,speeds` values no longer include turn penalty values ([#4330](https://github.com/Project-OSRM/osrm-backend/issues/4330))
# 5.9.1
- Infrastructure
- STXXL is not required by default
# 5.9.0
- Changes from 5.8:
- Algorithm:
- Multi-Level Dijkstra:
- Plugins supported: `table`
- Adds alternative routes support (see [#4047](https://github.com/Project-OSRM/osrm-backend/pull/4047) and [3905](https://github.com/Project-OSRM/osrm-backend/issues/3905)): provides reasonably looking alternative routes (many, if possible) with reasonable query times.
- API:
- Exposes `alternatives=Number` parameter overload in addition to the boolean flag.
- Support for exits numbers and names. New member `exits` in `RouteStep`, based on `junction:ref` on ways
- `Intersection` now has new parameter `classes` that can be set in the profile on each way.
- Profiles:
- `result.exits` allows you to set a way's exit numbers and names, see [`junction:ref`](http://wiki.openstreetmap.org/wiki/Proposed_features/junction_details)
- `ExtractionWay` now as new property `forward_classes` and `backward_classes` that can set in the `way_function`.
The maximum number of classes is 8.
- We now respect the `construction` tag. If the `construction` tag value is not on our whitelist (`minor`, `widening`, `no`) we will exclude the road.
- Node.js Bindings:
- Exposes `alternatives=Number` parameter overload in addition to the boolean flag
- Expose `EngineConfig` options in the node bindings
- Tools:
- Exposes engine limit on number of alternatives to generate `--max-alternatives` in `osrm-routed` (3 by default)
- Infrastructure
- STXXL is not required to build OSRM and is an optional dependency for back-compatibility (ENABLE_STXXL=On)
- OpenMP is only required when the optional STXXL dependency is used
- Bug fixes:
- #4278: Remove superflous continious instruction on a motorway.
# 5.8.0
- Changes from 5.7
- API:
- polyline6 support in request string
- new parameter `approaches` for `route`, `table`, `trip` and `nearest` requests. This parameter keep waypoints on the curb side.
'approaches' accepts both 'curb' and 'unrestricted' values.
Note : the curb side depend on the `ProfileProperties::left_hand_driving`, it's a global property set once by the profile. If you are working with a planet dataset, the api will be wrong in some countries, and right in others.
- NodeJs Bindings
- new parameter `approaches` for `route`, `table`, `trip` and `nearest` requests.
- Tools
- `osrm-partition` now ensures it is called before `osrm-contract` and removes inconsitent .hsgr files automatically.
- Features
- Added conditional restriction support with `parse-conditional-restrictions=true|false` to osrm-extract. This option saves conditional turn restrictions to the .restrictions file for parsing by contract later. Added `parse-conditionals-from-now=utc time stamp` and `--time-zone-file=/path/to/file` to osrm-contract
- Command-line tools (osrm-extract, osrm-contract, osrm-routed, etc) now return error codes and legible error messages for common problem scenarios, rather than ugly C++ crashes
- Speed up pre-processing by only running the Lua `node_function` for nodes that have tags. Cuts OSM file parsing time in half.
- osrm-extract now performs generation of edge-expanded-edges using all available CPUs, which should make osrm-extract significantly faster on multi-CPU machines
- Files
- .osrm.nodes file was renamed to .nbg_nodes and .ebg_nodes was added
- Guidance
- #4075 Changed counting of exits on service roundabouts
- Debug Tiles
- added support for visualising turn penalties to the MLD plugin
- added support for showing the rate (reciprocal of weight) on each edge when used
- added support for turn weights in addition to turn durations in debug tiles
- Bugfixes
- Fixed a copy/paste issue assigning wrong directions in similar turns (left over right)
- #4074: fixed a bug that would announce entering highway ramps as u-turns
- #4122: osrm-routed/libosrm should throw exception when a dataset incompatible with the requested algorithm is loaded
- Avoid collapsing u-turns into combined turn instructions
- Merged https://github.com/Project-OSRM/node-osrm into repository. Build via `cmake .. -DCMAKE_BUILD_TYPE=Release -DENABLE_NODE_BINDINGS=On -DENABLE_MASON=On`.
- `OSRM` object has new option `algorihtm="CH","CoreCH","MLD"`
- Internals
- Shared memory notification via conditional variables on Linux or semaphore queue on OS X and Windows with a limit of 128 OSRM Engine instances
- Files
- .osrm.datasource_index file was removed. Data is now part of .osrm.geometries.
- .osrm.edge_lookup was removed. The option `--generate-edge-lookup` does nothing now.
- `osrm-contract` does not depend on the `.osrm.fileIndex` file anymore
- `osrm-extract` creates new file `.osrm.cnbg` and `.cnbg_to_ebg`
- `osrm-partition` creates new file `.osrm.partition` and `.osrm.cells`
- `osrm-customize` creates new file `.osrm.mldgr`
- Profiles
- Added `force_split_edges` flag to global properties. True value guarantees that segment_function will be called for all segments, but also could double memory consumption
- Map Matching:
- new option `gaps=split|ignore` to enable/disbale track splitting
- new option `tidy=true|false` to simplify traces automatically

- Guidance
- No longer emitting turns on ferries, if a ferry should use multiple docking locations
- Profiles
- Removed the `./profile.lua -> ./profiles/car.lua` symlink. Use specific profiles from the `profiles` directory.
- `properties` object has a new `weight_name` field, default value is "duration"
- `properties` object has a new `weight_precision` field that specifies a decimal precision of edge weights, default value 1
- In `way_function` the filed `forward_rate` and `backward_rate` of `ExtractionWay` can now be set.
They have the same interpretation for the way weight as `forward_speed` and `backward_speed` for the edge duration.
The unit of rate is meters per weight unit, so higher values will be prefered during routing.
- `turn_function` now does not return an integer but takes in a `ExtractionTurn` object and can modify the `weight` and `duration` fields
- `segment_function` now takes in a `ExtractionSegment` object and can modify `weight` and `duration` fields
- `properties.uturn_penalty` is deprecated. Set it in the `turn_function`. The turn type is exposed as `ExtractionTurn::direction_modifier`.
- `properties.traffic_light_penalty` is deprecated. Traffic light penalties now need to be set over in the turn function.
Each turn with a traffic light is marked with `ExtractionTurn::has_traffic_light = true`.
- Renamed the helper file `profiles/lib/directional.lua` to `profiles/lib/tags.lua` since it now provides more general tags parsing utility functions.
- The car and foot profiles now depend on the helper file `profiles/lib/handlers.lua`.
- Infrastructure
- Disabled link-time optimized (LTO) builds by default. Enable by passing `-DENABLE_LTO=ON` to `cmake` if you need the performance and know what you are doing.
- Datafile versioning is now based on OSRM semver values, rather than source code checksums.
Datafiles are compatible between patch levels, but incompatible between minor version or higher bumps.
- libOSRM now creates an own watcher thread then used in shared memory mode to listen for data updates
- Tools:
- Added osrm-extract-conditionals tool for checking conditional values in OSM data
- Trip Plugin
- Added a new feature that finds the optimal route given a list of waypoints, a source and a destination. This does not return a roundtrip and instead returns a one way optimal route from the fixed source to the destination points.

Everyone is invited to participate in Project OSRM’s open source projects and public discussions: we want to create a welcoming and friendly environment. Harassment of participants or other unethical and unprofessional behavior will not be tolerated in our spaces. The [Contributor Covenant](http://contributor-covenant.org) applies to all projects under the Project-OSRM organization and we ask that you please read [the full text](http://contributor-covenant.org/version/1/2/0/).
could check code format, modify a local repository and reject push due to unstaged formatting changes.
Also `pre-push` hook rejects direct pushes to `origin/master`.
⚠️ `scripts/format.sh` checks all local files that match `*.cpp` or `*.hpp` patterns.
In general changes that affect the API and/or increase the memory consumption need to be discussed first.
Often we don't include changes that would increase the memory consumption a lot if they are not generally usable (e.g. elevation data is a good example).
## Pull Request
Every pull-request that changes the API needs to update the docs in `docs/http.md` and add an entry to `CHANGELOG.md`.
Breaking changes need to have a BREAKING prefix. See the [releasing documentation](docs/releasing.md) on how this affects the version.
Early feedback is also important.
You will see that a lot of the PR have tags like `[not ready]` or `[wip]`.
We like to open PRs as soon as we are starting to work on something to make it visible to the rest of the team.
If your work is going in entirely the wrong direction, there is a good chance someone will pick up on this before it is too late.
Everyone is encouraged to read PRs of other people and give feedback.
For every significant code change we require a pull request review before it is merged.
If your pull request modifies the API this need to be signed of by a team discussion.
This means you will need to find another member of the team with commit access and request a review of your pull request.
Once your pull request is reviewed you can merge it! If you don't have commit access, ping someone that has commit access.
If you do have commit access there are in general two accepted styles to merging:
1. Make sure the branch is up to date with `master`. Run `git rebase master` to find out.
2. Once that is ensured you can either:
- Click the nice green merge button (for a non-fast-forward merge)
- Merge by hand using a fast-forward merge
Which merge you prefer is up to personal preference. In general it is recommended to use fast-forward merges because it creates a history that is sequential and easier to understand.
# Maintainer
## Doing a release
There is an in-depth guide around how to push out a release once it is ready [here](docs/releasing.md).
## The API
Changes to the API need to be discussed and signed off by the team. Breaking changes even more so than additive changes.
## Milestones
If a pull request or an issue is applicable for the current or next milestone, depends on the target version number.
Since we use semantic versioning we restrict breaking changes to major releases.
After a Release Candidate is released we usually don't change the API anymore if it is not critical.
Bigger code changes after a RC was released should also be avoided.

## Documentation
### Full documentation

- [osrm-routed HTTP API documentation](docs/http.md)
- [libosrm API documentation](docs/libosrm.md)
### Quick start
## Contact
Building OSRM assuming all dependencies are installed:
The easiest and quickest way to setup your own routing engine is to use Docker images we provide.
There are two pre-processing pipelines available:
- Contraction Hierarchies (CH)
- Multi-Level Dijkstra (MLD)
we recommend using MLD by default except for special use-cases such as very large distance matrices where CH is still a better fit for the time being.
In the following we explain the MLD pipeline.
If you want to use the CH pipeline instead replace `osrm-partition` and `osrm-customize` with a single `osrm-contract` and change the algorithm option for `osrm-routed` to `--algorithm ch`.
### Using Docker
We base our Docker images ([backend](https://github.com/Project-OSRM/osrm-backend/pkgs/container/osrm-backend), [frontend](https://hub.docker.com/r/osrm/osrm-frontend/)) on Debian and make sure they are as lightweight as possible. Older backend versions can be found on [Docker Hub](https://hub.docker.com/r/osrm/osrm-backend/).
Download OpenStreetMap extracts for example from [Geofabrik](http://download.geofabrik.de/)
The flag `-v "${PWD}:/data"` creates the directory `/data` inside the docker container and makes the current working directory `"${PWD}"` available there. The file `/data/berlin-latest.osm.pbf` inside the container is referring to `"${PWD}/berlin-latest.osm.pbf"` on the host.
Note there is no `berlin-latest.osrm` file, but multiple `berlin-latest.osrm.*` files, i.e. `berlin-latest.osrm` is not file path, but "base" path referring to set of files and there is an option to omit this `.osrm` suffix completely(e.g. `osrm-partition /data/berlin-latest`).
SET(CPACK_PACKAGE_DESCRIPTION_SUMMARY"Open Source Routing Machine (OSRM) is a high-performance routing engine. It combines sophisticated routing algorithms with the open and free data of the OpenStreetMap.")

When changing guidance code, it is easy to introduce problems somewhere in the network.
To get a better feeling of how your changes impact the OSRM experience, we offer ways of generating geojson output to inspect (e.g. with Mapbox Studio).
When you do changes, make sure to inspect a few areas for the impact of the changes.
## How to use GeoJson-Debugging
This is a short guide to describe usage of our GeoJson debug logging mechanism. It is synchronized to guarantee thread-safe logging.
## Outputting into a single file
To use it, the inclusion of `geojson_debug_logger.hpp``geojson_debug_policies.hpp` from the `util` directory is required.
Geojson debugging requires a few simple steps to output data into a feature collection.
- Create a Scoped Guard that lives through the process and provide it with all required datastructures (it needs to span the lifetime of all your logging efforts)
- At the location of the output, simply call Write with your own parameters.
A guard (ScopedGeojsonLoggerGuard) requires a logging policy. Per default we provide a way of printing out node-ids as coordinates.
Make sure to give the guard a name, so it actually gets a lifetime.
The field `data-for-conversion` can be an arbitrary long set of features and needs to match the parameters used for constructing our policy (in this case `util::NodeIdVectorToLineString`).
The policy itself offers a `operator()` accepting a `vector` of `NodeID`.
For outputting data into our file (debug.geojson), we simply need to call the matching logging routine of the guard: `util::ScioedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids);`
(or `guard.Write(list_of_node_ids)` if you created an instance).
### Possible Scopeguard Location
Think of the scopeguard as you would do of any reference. If you wan't to access to logging during a call, the guard object must be alive and valid.
As an example: a good location to create a scopeguard to log decisions in the edge-based-graph-factory would be right before we run it ([here](https://github.com/Project-OSRM/osrm-backend/blob/a933b5d94943bf3edaf42c84a614a99650d23cba/src/extractor/extractor.cpp#L497)). If you put `util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", node_coordinate_vector);` at that location, you can then print `util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids);` anywhere within the `edge-based-graph-factory`.
This location would enable calls for all guidance related pre-processing which is called in the edge-based-graph-factory.
Logging any turn-handler decisions, for example, would now be possible.
## Limitations
GeoJson debugging requires a single GeoJsonGuard (ScopedGeojsonLoggerGuard) for each desired output file.
For each set of template parameters, only the most recent guard will actually produce output.
OSRM can be used as a library (libosrm) via C++ instead of using it through the HTTP interface and `osrm-routed`. This allows for fine-tuning OSRM and has much less overhead. Here is a quick introduction into how to use `libosrm` in the upcoming v5 release.
Take a look at the example code that lives in the [example directory](https://github.com/Project-OSRM/osrm-backend/tree/master/example). Here is all you ever wanted to know about `libosrm`, that is a short description of what the types do and where to find documentation on it:
## Important interface objects
- [`EngineConfig`](https://github.com/Project-OSRM/osrm-backend/blob/master/include/engine/engine_config.hpp) - for initializing an OSRM instance we can configure certain properties and constraints. E.g. the storage config is the base path such as `france.osm.osrm` from which we derive and load `france.osm.osrm.*` auxiliary files. This also lets you set constraints such as the maximum number of locations allowed for specific services.
- [`OSRM`](https://github.com/Project-OSRM/osrm-backend/blob/master/include/osrm/osrm.hpp) - this is the main Routing Machine type with functions such as `Route` and `Table`. You initialize it with a `EngineConfig`. It does all the heavy lifting for you. Each function takes its own parameters, e.g. the `Route` function takes `RouteParameters`, and a out-reference to a JSON result that gets filled. The return value is a `Status`, indicating error or success.

- [Parameters for other services](https://github.com/Project-OSRM/osrm-backend/tree/master/include/engine/api) - here are all other `*Parameters` you need for other Routing Machine services.
- [JSON](https://github.com/Project-OSRM/osrm-backend/blob/master/include/util/json_container.hpp) - this is a sum type resembling JSON. The Routing Machine service functions take a out-ref to a JSON result and fill it accordingly. It is currently implemented using [mapbox/variant](https://github.com/mapbox/variant) which is similar to [Boost.Variant](http://www.boost.org/doc/libs/1_55_0/doc/html/variant.html) (Boost documentation is great). There are two ways to work with this sum type: either provide a visitor that acts on each type on visitation or use the `get` function in case you're sure about the structure. The JSON structure is written down in the [[v5 server API|Server-API-v5,-current]].

### trip
The trip plugin solves the Traveling Salesman Problem using a greedy heuristic
(farthest-insertion algorithm) for 10 or _ more waypoints and uses brute force for less than 10
waypoints. The returned path does not have to be the shortest path, _ as TSP is NP-hard it is
only an approximation.
Note that all input coordinates have to be connected for the trip service to work.
Currently, not all combinations of `roundtrip`, `source` and `destination` are supported.
Right now, the following combinations are possible:
| roundtrip | source | destination | supported |
| :-------- | :----- | :---------- | :-------- |

`options.format` is `flatbuffers`), which will return a NodeJS
**[Buffer](https://nodejs.org/api/buffer.html)** object, containing a JSON string or Flatbuffers
object. The latter has the advantage that it can be immediately serialized to disk/sent over the
network, and the generation of the string is performed outside the main NodeJS event loop. This
option is ignored by the `tile` plugin. Also note that `options.format` set to `flatbuffers`
cannot be used with `plugin_config.format` set to `object`. `json_buffer` is deprecated alias for
OSRM supports "profiles". Configurations representing different routing behaviours for (typically) different transport modes. A profile describes whether or not we route along a particular type of way, or over a particular node in the OpenStreetMap data, and also how quickly we'll be travelling when we do. This feeds into the way the routing graph is created and thus influences the output routes.
# OSRM profiles
OSRM supports "profiles". Profiles representing routing behavior for different transport modes like car, bike and foot. You can also create profiles for variations like a fastest/shortest car profile or fastest/safest/greenest bicycles profile.
A profile describes whether or not it's possible to route along a particular type of way, whether we can pass a particular node, and how quickly we'll be traveling when we do. This feeds into the way the routing graph is created and thus influences the output routes.
## Available profiles
Out-of-the-box OSRM comes with profiles for car, bicycle and foot. You can easily modify these or create new ones if you like.
Out-of-the-box OSRM comes with several different profiles, including car, bicycle and foot.
Profiles have a 'lua' extension, and are placed in 'profiles' directory.
Profile configuration files have a 'lua' extension, and are found under the 'profiles' subdirectory.
Alternatively commands will take a lua profile specified with an explicit -p param, for example:
When running OSRM preprocessing commands you specify the profile with the --profile (or the shorthand -p) option, for example:
And then **you will need to extract and contract again** (A change to the profile will typically affect the extract step as well as the contract step. See [Processing Flow](https://github.com/Project-OSRM/osrm-backend/wiki/Processing-Flow))
## Processing flow
It's important to understand that profiles are used when preprocessing the OSM data, NOT at query time when routes are computed.
## lua scripts?
This means that after modifying a profile **you will need to extract, contract and reload the data again** and to see changes in the routing results. See [Processing Flow](https://github.com/Project-OSRM/osrm-backend/wiki/Processing-Flow) for more.
Profiles are not just configuration files. They are scripts written in the "lua" scripting language ( http://www.lua.org ) The reason for this, is that OpenStreetMap data is not sufficiently straightforward, to simply define tag mappings. Lua scripting offers a powerful way of coping with the complexity of different node,way,relation,tag combinations found within OpenStreetMap data.
## Profiles are written in Lua
Profiles are not just configuration files. They are scripts written in the [Lua scripting language](http://www.lua.org). The reason for this is that OpenStreetMap data is complex, and it's not possible to simply define tag mappings. Lua scripting offers a powerful way to handle all the possible tag combinations found in OpenStreetMap nodes and ways.
## Basic structure of a profile
## Basic structure of profiles
A profile will process every node and way in the OSM input data to determine what ways are routable in which direction, at what speed, etc.
You can understand these lua scripts enough to make interesting modifications, without needing to get to grips with how they work completely.
A profile will typically:
Towards the top of the file, a profile (such as [car.lua](../profiles/car.lua)) will typically define various configurations as global variables. A lot of these are look-up hashes of one sort or another.
- Define api version (required)
- Require library files (optional)
- Define setup function (required)
- Define process functions (some are required)
- Return functions table (required)
As you scroll down the file you'll see local variables, and then local functions, and finally...
A profile can also define various local functions it needs.
`way_function` and `node_function` are the important functions which are called when extracting OpenStreetMap data with `osrm-extract`.
Looking at [car.lua](../profiles/car.lua) as an example, at the top of the file the api version is defined and then required library files are included.
## way_function
Then follows the `setup` function, which is called once when the profile is loaded. It returns a big hash table of configurations, specifying things like what speed to use for different way types. The configurations are used later in the various processing functions. Many adjustments can be done just by modifying this configuration table.
Given an OpenStreetMap way, the way_function will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash to be returned. The most important thing it will do is set the value of `result.forward_speed` and `result.backward_speed` as a suitable integer value representing the speed for traversing the way.
The setup function is also where you can do other setup, like loading an elevation data source if you want to consider that when processing ways.
All other calculations stem from that, including the returned timings in driving directions, but also, less directly, it feeds into the actual routing decisions the engine will take (a way with a slow traversal speed, may be less favoured than a way with fast traversal speed, but it depends how long it is, and... what it connects to in the rest of the network graph)
Then come the `process_node` and `process_way` functions, which are called for each OSM node and way when extracting OpenStreetMap data with `osrm-extract`.
Using the power of the scripting language you wouldn't typically see something as simple as a `result.forward_speed = 20` line within the way_function. Instead a way_function will examine the tagging (e.g. `way:get_value_by_key("highway")` and many others), process this information in various ways, calling other local functions, referencing the global variables and look-up hashes, before arriving at the result.
The `process_turn` function processes every possible turn in the network, and sets a penalty depending on the angle and turn of the movement.
Profiles can also define a `process_segment` function to handle differences in speed along an OSM way, for example to handle elevation. As you can see, this is not currently used in the car profile.
At the end of the file, a table is returned with references to the setup and processing functions the profile has defined.
## Understanding speed, weight and rate
When computing a route from A to B there can be different measures of what is the best route. That's why there's a need for different profiles.
Because speeds vary on different types of roads, the shortest and the fastest route are typically different. But there are many other possible preferences. For example a user might prefer a bicycle route that follow parks or other green areas, even though both duration and distance are a bit longer.
To handle this, OSRM doesn't simply choose the ways with the highest speed. Instead it uses the concepts of `weight` and `rate`. The rate is an abstract measure that you can assign to ways as you like to make some ways preferable to others. Routing will prefer ways with high rate.
The weight of a way is normally computed as length / rate. The weight can be thought of as the resistance or cost when passing the way. Routing will prefer ways with low weight.
You can also set the weight of a way to a fixed value. In this case it's not calculated based on the length or rate, and the rate is ignored.
You should set the speed to your best estimate of the actual speed that will be used on a particular way. This will result in the best estimated travel times.
If you want to prefer certain ways due to other factors than the speed, adjust the rate accordingly. If you adjust the speed, the time estimation will be skewed.
If you set the same rate on all ways, the result will be shortest path routing.
If you set rate = speed on all ways, the result will be fastest path routing.
If you want to prioritize certain streets, increase the rate on these.
## Elements
### api_version
A profile should set `api_version` at the top of your profile. This is done to ensure that older profiles are still supported when the api changes. If `api_version` is not defined, 0 will be assumed. The current api version is 4.
### Library files
The folder [profiles/lib/](../profiles/lib/) contains LUA library files for handling many common processing tasks.
File | Notes
------------------|------------------------------
way_handlers.lua | Functions for processing way tags
tags.lua | Functions for general parsing of OSM tags
set.lua | Defines the Set helper for handling sets of values
sequence.lua | Defines the Sequence helper for handling sequences of values
access.lua | Function for finding relevant access tags
destination.lua | Function for finding relevant destination tags
maxspeed.lua | Function for determining maximum speed
guidance.lua | Function for processing guidance attributes
They all return a table of functions when you use `require` to load them. You can either store this table and reference its functions later, or if you need only a single function you can store that directly.
### setup()
The `setup` function is called once when the profile is loaded and must return a table of configurations. It's also where you can do other global setup, like loading data sources that are used during processing.
Note that processing of data is parallelized and several unconnected LUA interpreters will be running at the same time. The `setup` function will be called once for each. Each LUA interpreter will have its own set of globals.
The following global properties can be set under `properties` in the hash you return in the `setup` function:
left_hand_driving | Boolean | Are vehicles assumed to drive on the left? (used in guidance, default `false`)
use_turn_restrictions | Boolean | Are turn restrictions followed? (default `false`)
continue_straight_at_waypoint | Boolean | Must the route continue straight on at a via point, or are U-turns allowed? (default `true`)
max_speed_for_map_matching | Float | Maximum vehicle speed to be assumed in matching (in m/s)
max_turn_weight | Float | Maximum turn penalty weight
force_split_edges | Boolean | True value forces a split of forward and backward edges of extracted ways and guarantees that `process_segment` will be called for all segments (default `false`)
The following additional global properties can be set in the hash you return in the `setup` function:
excludable | Sequence of Sets | Determines which class-combinations are supported by the `exclude` option at query time. E.g. `Sequence{Set{"ferry", "motorway"}, Set{"motorway"}}` will allow you to exclude ferries and motorways, or only motorways.
classes | Sequence | Determines the allowed classes that can be referenced using `{forward,backward}_classes` on the way in the `process_way` function.
restrictions | Sequence | Determines which turn restrictions will be used for this profile.
suffix_list | Set | List of name suffixes needed for determining if "Highway 101 NW" the same road as "Highway 101 ES".
relation_types | Sequence | Determines which relations should be cached for processing in this profile. It contains relations types
traffic_lights | Boolean | Is it a traffic light (incurs delay in `process_turn`)?
### process_way(profile, way, result, relations)
Given an OpenStreetMap way, the `process_way` function will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash.
profile | The configuration table you returned in `setup`.
way | The input way to process (read-only).
result | The output that you will modify.
relations| Storage of relations to access relations, where `way` is a member.
Importantly it will set `result.forward_mode` and `result.backward_mode` to indicate the travel mode in each direction, as well as set `result.forward_speed` and `result.backward_speed` to integer values representing the speed for traversing the way.
It will also set a number of other attributes on `result`.
Using the power of the scripting language you wouldn't typically see something as simple as a `result.forward_speed = 20` line within the `process_way` function. Instead `process_way` will examine the tag set on the way, process this information in various ways, calling other local functions and referencing the configuration in `profile`, etc., before arriving at the result.
The following attributes can be set on the result in `process_way`:
forward_speed | Float | Speed on this way in km/h. Mandatory.
backward_speed | Float | ""
forward_rate | Float | Routing weight, expressed as meters/*weight* (e.g. for a fastest-route weighting, you would want this to be meters/second, so set it to forward_speed/3.6)
backward_rate | Float | ""
forward_mode | Enum | Mode of travel (e.g. `car`, `ferry`). Mandatory. Defined in `include/extractor/travel_mode.hpp`.
backward_mode | Enum | ""
forward_classes | Table | Mark this way as being of a specific class, e.g. `result.classes["toll"] = true`. This will be exposed in the API as `classes` on each `RouteStep`.
backward_classes | Table | ""
duration | Float | Alternative setter for duration of the whole way in both directions
weight | Float | Alternative setter for weight of the whole way in both directions
turn_lanes_forward | String | Directions for individual lanes (normalized OSM `turn:lanes` value)
turn_lanes_backward | String | ""
forward_restricted | Boolean | Is this a restricted access road? (e.g. private, or deliveries only; used to enable high turn penalty, so that way is only chosen for start/end of route)
backward_restricted | Boolean | ""
is_startpoint | Boolean | Can a journey start on this way? (e.g. ferry; if `false`, prevents snapping the start point to this way)
roundabout | Boolean | Is this part of a roundabout?
circular | Boolean | Is this part of a non-roundabout circular junction?
name | String | Name of the way
ref | String | Road number (equal to set `forward_ref` and `backward_ref` with one value)
forward_ref | String | Road number in forward way direction
backward_ref | String | Road number in backward way direction
destinations | String | The road's destinations
exits | String | The ramp's exit numbers or names
pronunciation | String | Name pronunciation
road_classification.motorway_class | Boolean | Guidance: way is a motorway
road_classification.link_class | Boolean | Guidance: way is a slip/link road
road_classification.road_priority_class | Enum | Guidance: order in priority list. Defined in `include/extractor/road_classification.hpp`

road_classification.num_lanes | Unsigned | Guidance: total number of lanes in way
### process_segment(profile, segment)
The `process_segment` function is called for every segment of OSM ways. A segment is a straight line between two OSM nodes.
On OpenStreetMap way cannot have different tags on different parts of a way. Instead you would split the way into several smaller ways. However many ways are long. For example, many ways pass hills without any change in tags.
Processing each segment of an OSM way makes it possible to have different speeds on different parts of a way based on external data like data about elevation, pollution, noise or scenic value and adjust weight and duration of the segment accordingly.
In the `process_segment` function you don't have access to OSM tags. Instead you use the geographical location of the start and end point of the way to look up information from another data source, like elevation data. See [rasterbot.lua](../profiles/rasterbot.lua) for an example.
The following attributes can be read and set on the result in `process_segment`:
source.lon | Read | Float | Co-ordinates of segment start
source.lat | Read | Float | ""
target.lon | Read | Float | Co-ordinates of segment end
target.lat | Read | Float | ""
distance | Read | Float | Length of segment
weight | Read/write | Float | Routing weight for this segment
duration | Read/write | Float | Duration for this segment
### process_turn(profile, turn)
The `process_turn` function is called for every possible turn in the network. Based on the angle and type of turn you assign the weight and duration of the movement.

target_mode | Read | Enum | Travel mode after the turn. Defined in `include/extractor/travel_mode.hpp`
target_is_motorway | Read | Boolean | Is the target road a motorway?
target_is_link | Read | Boolean | Is the target road a link?
target_number_of_lanes | Read | Integer | How many lanes does the target road have? (default when not tagged: 0)

#### `roads_on_the_right` and `roads_on_the_left`
The information of `roads_on_the_right` and `roads_on_the_left` that can be read are as follows:
is_restricted | Read | Boolean | Is it a restricted access road? (See definition in `process_way`)
mode | Read | Enum | Travel mode before the turn. Defined in `include/extractor/travel_mode.hpp`
is_motorway | Read | Boolean | Is the road a motorway?

The order of the roads in `roads_on_the_right` and `roads_on_the_left` are *counter clockwise*. If the turn is a u turn, all other connected roads will be in `roads_on_the_right`.
**Example**
```
c e
| /
| /
a ---- x ---- b
/|
/ |
f d
```
When turning from `a` to `b` via `x`,
* `roads_on_the_right[1]` is the road `xf`
* `roads_on_the_right[2]` is the road `xd`
* `roads_on_the_left[1]` is the road `xe`
* `roads_on_the_left[2]` is the road `xc`
Note that indices of arrays in lua are 1-based.
#### `highway_turn_classification` and `access_turn_classification`
When setting appropriate turn weights and duration, information about the highway and access tags of roads that are involved in the turn are necessary. The lua turn function `process_turn` does not have access to the original osrm tags anymore. However, `highway_turn_classification` and `access_turn_classification` can be set during setup. The classification set during setup can be later used in `process_turn`.
**Example**
In the following example we use `highway_turn_classification` to set the turn weight to `10` if the turn is on a highway and to `5` if the turn is on a primary.
```
function setup()
return {
highway_turn_classification = {
['motorway'] = 2,
['primary'] = 1
}
}
end
function process_turn(profile, turn) {
if turn.source_highway_turn_classification == 2 and turn.target_highway_turn_classification == 2 then
turn.weight = 10
end
if turn.source_highway_turn_classification == 1 and turn.target_highway_turn_classification == 1 then
turn.weight = 5
end
}
```
## Guidance
The guidance parameters in profiles are currently a work in progress. They can and will change.
Please be aware of this when using guidance configuration possibilities.
Guidance uses road classes to decide on when/if to emit specific instructions and to discover which road is obvious when following a route.
Classification uses three flags and a priority-category.
The flags indicate whether a road is a motorway (required for on/off ramps), a link type (the ramps itself, if also a motorway) and whether a road may be omitted in considerations (is considered purely for connectivity).
The priority-category influences the decision which road is considered the obvious choice and which roads can be seen as fork.
Forks can be emitted between roads of similar priority category only. Obvious choices follow a major priority road, if the priority difference is large.
### Using raster data
OSRM has built-in support for loading an interpolating raster data in ASCII format. This can be used e.g. for factoring in elevation when computing routes.
Use `raster:load()` in your `setup` function to load data and store the source in your configuration hash:
```lua
function setup()
return {
raster_source = raster:load(
"rastersource.asc", -- file to load
0, -- longitude min
0.1, -- longitude max
0, -- latitude min
0.1, -- latitude max
5, -- number of rows
4 -- number of columns
)
}
end
```
The input data must an ASCII file with rows of integers. e.g.:
```
0 0 0 0
0 0 0 250
0 0 250 500
0 0 0 250
0 0 0 0
```
In your `segment_function` you can then access the raster source and use `raster:query()` to query to find the nearest data point, or `raster:interpolate()` to interpolate a value based on nearby data points.
You must check whether the result is valid before using it.
Example:
```lua
function process_segment (profile, segment)
local sourceData = raster:query(profile.raster_source, segment.source.lon, segment.source.lat)
local targetData = raster:query(profile.raster_source, segment.target.lon, segment.target.lat)
local invalid = sourceData.invalid_data()
if sourceData.datum ~= invalid and targetData.datum ~= invalid then
-- use values to adjust weight and duration
[...]
end
```
See [rasterbot.lua](../profiles/rasterbot.lua) and [rasterbotinterp.lua](../profiles/rasterbotinterp.lua) for examples.
### Helper functions
There are a few helper functions defined in the global scope that profiles can use:
Do decide if this is a major or minor version bump use: http://semver.org/
We are using http://semver.org/ for versioning with major, minor and patch versions.
What we guarantee on major version changes:

1. Make sure all tests are passing (e.g. Travis CI gives you a :thumbs_up:)
## Release and branch management
- The `master` branch is for the bleeding edge development
- We create and maintain release branches `x.y` to control the release flow
- We create the release branch once we create release branches once we want to release the first RC
- RCs go in the release branch, commits needs to be cherry-picked from master
- No minor or major version will be released without a code-equal release candidates
- For quality assurance, release candidates need to be staged beforing tagging a final release
- Patch versions may be released without a release candidate
- We may backport fixes to older versions and release them as patch versions

#### Don't Rely on Alternatives
Alternative route discovery is a random feature in itself. The discovery of routes depends on the contraction order of roads and cannot be assumed successful, ever.
### Understanding Turn Restrictions
Adding turn restrictions requires the restriction to follow a very specific format.
We specify them in a table with the header `| type | way:from | way:to | node:via | restriction |`.
It is important that turn restrictions require micro segmentation.
The setting looks perfectly fine at first glance. However, it is not well defined.
The forbidden right turn could be either a superfluous addition, forbidding the turn `cb` to `be`, or actually refer to the turn `ab` to `bd` to say that a turn is forbidden here.
To model turn-restrictions correctly and uniquely, we need to split segments that contribute to the restriction into the smallest possible parts.
E.g. the above scenario could correctly be expressed as:
Unless this format is used, OSRM will omit the (then ambiguous) turn restrictions and ignore them.
## My Guidance Tests are Failing - Understanding what you can change
If you change some stuff in guidance, you will easily see tests change their result. E.g. if you change the angles for which we report `right`, then obviously some tests might not report a `direction modifier` named `right` anymore.
This small section will try to guide you in making the correct decisions for changing the behaviour of tests.
The difficulty in guidance tests is that not all items can be translated 1:1 from the ascii art into turn-angles.
The turn-angle calculation tries to find turn angles that would represent perceived turn angles, not the exact angle at the connection.
This is necessary, since connections in OSM are always bound by the paradigm that the way is supposed to be in the middle of the actual road.
For broad streets, you will see stronger angles than the actual turns.
### Don't change the test, change the expected behaviour
And the test reports `turn right` for the route `a->e`, where before it said `slight right`.
If you change the turn angles, obviously you can expect changes in the distinction between `slight right` and `right`.
In such a case it is, of course, reasonable to change the expected route to report `right` instead of `slight right`. You should consider inspecting the actual turn angles at `b` to see if you feel that change is justified.
However, you should never adjust the test itself.
If you look at a failure, the other way around
```
Given a grid size of 5 m
Given the node map
"""
a - b - - - - - - c
\
d - - - - - e
"""
When I route I should get
| waypoints | route | turns |
| a,e | abc,bde,bde | depart,turn right,arrive|
```
where we see a `slight right`, over the expected `right`.
We could be tempted to adjust the grid size (e.g. from `10 m` to `20` meters).
Such a change would fundamentally alter the tests, though.
Since the part `b-d` is a short offset, when we are looking at a grid of size `5 m`, the angle calculation will try and compensate for this offset.
In this case we would see a very slight turn angle. If your change now reports different turn angles, you can of course change the expected result. But you should not adjust the grid size. The test would be testing turn angles of `180` and `100` degrees, instead of `180` and `160`.
### Consider Post-Processing Impacts
Some changes you might see could look completely unrelated. To understand the impact of your changes, you can make use of the debugging utilities you can find in `util/debug.hpp` (and potentially other related headers).
If your test is inspecting a series of turns (remember, a turn does not necessarily equals an instruction), you could see interaction with post-processing.
To see the unprocessed turns, you should print the steps at the end of step assembly (`assembleSteps` in `engine/guidance/assemble_steps.hpp`).
If you see unexpected changes, you can consider adding the `locations` field to your test to study what location a turn is reported at.
To study a test without post-processing impacts, you can create a copy of the case on a very large grid (like 2000 meters). In such a grid, `turn collapsing` would be essentially disable.
Sadly, there is no general guideline.
### Use Caution
If in doubt, ask another person. Inspect as much of the data as possible (e.g. print un-collapsed steps, turn angles and so on) and use your best judgement, if the new result seems justified.
