As of 2022-03-31, the versioning for cartographer_ros is in a complicated situation.
|
|
Upstream https://github.com/cartographer-project/cartographer_ros seems to be moribund,
|
|
with no commits for close to a year. The master branch there is only for ROS 1, and
|
|
that branch has not had a released tag since 1.0.0 in 2018.
|
|
|
|
In the meantime, we've done a port to ROS 2 in https://github.com/ros2/cartographer_ros
|
|
that targets upstream cartographer 2.0.0.
|
|
|
|
Since we have no response from upstream in a long time, we are going to go ahead and
|
|
assume that the 1.x series of tags from upstream cartographer_ros will always be used
|
|
to target ROS 1. Further we are going to assume that the 2.x series of tags
|
|
from upstream cartographer_ros (none of which exist yet) will be used to target ROS 2.
|
|
If upstream comes alive and chooses a different versioning scheme, we can adjust later
|
|
as necessary. The outcome of all of this is that we are assuming a starting "upstream"
|
|
release of 2.0.0, which then plays into the rest of the explanation below.
|
|
|
|
We add 900 to the patch part of the version and then multiply it by 10,
|
|
i.e. our version = `(upstream_patch_version + 900) * 10`,
|
|
so we can have intermediate releases as well as release any future official 2.0.x versions.
|
|
|
|
This is basically packing the patch part of the version and a fourth version part together
|
|
into the third part of the version.
|
|
|
|
The use of `900` instead of something else like `100` is arbitrary, but it might
|
|
help people recognize that this is a "special" version number.
|
|
It is needed however, because we cannot have a leading `0` in our patch version.
|
|
|
|
Consider these possible future versions as an example:
|
|
|
|
2.0.9000 -> current state of this repository, 2.0.0 + some commits from us
|
|
2.0.9010 -> upstream 2.0.1
|
|
2.0.9011 -> upstream 2.0.1 + additional commits from upstream or us
|
|
2.0.9012 -> upstream 2.0.1 + additional commits from 2.0.1011 + more new commits
|
|
2.0.9020 -> upstream 2.0.2
|
|
and so on...
|
|

|
|
<version>2.0.9003</version>
