# Description

For the cluster deployment, the latest docker version (25.xx) is not yet
compatible with the latest apptainer version. This PR adds a check
before building the singularity image and adds a warning to the docs.
Also the NOHTTPS warning has been resolved.

Fixes #371

# Description

Adds remaining compat tests to `tests_to_skip.py` in response to [this
conversation
](https://github.com/isaac-orbit/orbit/pull/401#discussion_r1489481352).
When we are ready to full deprecate `/compat`, we should then fully
remove these tests from the code base.

Fixes #400

# Description

A user had a typo in their input prim path to the asset class. They did
"World/Robot" instead of "/World/Robot". The error message they got
because of this was out-of-index which is confusing.

This MR adds a check for global paths and gives a cleaner error message.

# Description

This MR fixes the issue with printing articulation joint information
with the `Articulation` class. When the number of joints are 1, the
`squeeze(0).tolist()` operation makes the tensor a float item instead of
a list.

This MR removes the squeeze operation and adds a unit test to check that
single-joint articulations work.

# Description

Previously, if you had two environments named `orbit` and `orbit_2024`.
If you delete the environment `orbit` to rename it, the grep search
would try to match `orbit_2024` with `orbit` and say the environment
exists.

This MR fixes the grep matching in `orbit.sh` to return success only if
the entire word matches.

# Description

As we are dropping support for Isaac Sim 2022.2, this MR updates the
pre-commit and setup.py to check for Python 3.10 language. Notable
changes when the formatter was run:

* `typing-extensions` has been merged to `typing`
* `collections.abc` is favored over `typing` for importing generic
types. The latter will be deprecated in future Python releases.

# Description

We frequently reinstall pip packages when building the docker, even when
the downloaded packages have not changed between builds. This allows us
to look in `/root/.cache/pip` (on the image) for cached pip packages.
This speeds up our build significantly.

Adds a [mount cache
](https://docs.docker.com/build/cache/#use-the-dedicated-run-cache)to
the Dockerfile for the line `${ORBIT_PATH}/orbit.sh --install --extra`,
significantly increasing speeds by preventing repeated downloads of
large packages

# Description

This MR pins the torch version to 2.0.1 in installing the `orbit` and
`orbit_tasks` extensions. This helps fix the torch and typing_extensions
version incompatibility reported in #373.

Previously, torch version 2.2 was getting downloaded on a fresh
installation, which caused an error when trying to import it after
launching Isaac Sim: `NameError: name '_C' is not defined. Did you mean:
'_'?`

# Description

On termination of an episode, three conditions arise:

1. **bad** terminations (terminated dones): the agent gets a termination
penalty
2. **timeout** terminations (truncated dones):
* infinite-horizon: bootstrapping by the agent based on terminal state
    * finite-horizon: no penalty or bootstrapping

Currently, we have not handled the last case, which leads to issues when
training RL tasks with a finite horizon (for instance, Nikita's agile
locomotion work).

This MR adds a flag to the RLTaskEnvCfg called `is_finite_horizon` that
helps deal with this case. The flag is consumed by the env wrappers to
decide how they want to specifically handle the finite horizon problem.

From Isaac `2023.1.0-hotfix.1` to `2023.1.1`, `/app/livestream/enabled`
started to default to True. This breaks our logic w/r/t
`SimulationContext.render()`, which is now treating a headless instance
as one that needs full rendering. This causes problems with multiple
SimulationContext calls, and ultimately this bottoms out with this
[line](https://github.com/isaac-orbit/orbit/blob/670a8c97db645d50a3ea89b06f7366fc2212fc06/source/extensions/omni.isaac.orbit/omni/isaac/orbit/sim/simulation_context.py#L563)
sending us into an infinite rendering cycle from which i.e. unittest
cannot exit.

I fix this problem by setting `/app/livestream/enabled` to explicitly
False in AppLauncher unless otherwise requested. This corrects the hang.

Ultimately, the answer to this is #238, but in the meantime we need a
fix or this is a showstopper for unit testing.

Fixes #323

# Description

We currently have X11 forwarding enabled by default. This is convenient
for certain users who want graphical displays (including IsaacSim
itself) to be forwarded from within the container. However, it is also
partially dependent upon the configuration of the host system and
requires a valid .Xauthority file which may or may not have been
created. Because this has introduced difficulties for several of our
users, I submit that we comment this portion out be default, until a
solution which allows either a `./container.sh` option, a variable in
`.env`, or both can be used to conveniently enable this option on an
affirmative basis.

If we can agree on this change, I will update the documentation
correspondingly.

# Description

The FrameTransformer sensor always assumed that the source frame index
is 0 in the parsed regex expression. However, a recent issue appeared
where this is not the case, and it led to a bug due to the hard-coded
value. This MR fixes the source frame index in the sensor and also adds
a unit test to check this behavior.

# Description

This PR adds a script to run all the unit tests (any Python script named
`test_*.py`) and report on the success rate and timing. It also enables
the skipping of known breaking tests via tests_to_skip.py. The tests can
be run via `orbit -t`, and the test output will be printed to both a log
(`test_results.log`) and to the console.

This can be used for CI/CD but also can be temporarily used to run each
test without invoking them manually one by one until we have a better
solution.

A few tests are currently broken; for now, these are added to
tests_to_skip - I will put follow-up issues + PRs to fix these as soon
as possible. I recommend we add running tests as a requirement before
merging PRs until the CI/CD project is complete, too. One way to help
facilitate this is to have PR authors copy/paste the results at the end
of the test run to the PR description.

Fixes #309 

## Type of change

- New feature (non-breaking change which adds functionality)

# Description

This PR fixes three issues related to cluster deployment:

- remove the explicit copy of `orbit_assets` directory in the
`container.sh` file
- Direct bind the `logs` directory in the `run_singularity.sh` file to
make sure that the logs are copied when the run crashed
- Create an additional file in the docker to make sure it exists when
binded when the singularity is run

# Description

Currently, the very first tutorial for users is the app launcher. This

launcher tutorial and puts it later in the part 1 of the tutorials.
