Basilisk Known Issues

Caution

The use of cMsgCInterfacePy is depreciated. Use messaging instead.

Version 2.5.23 

pip-based installation in editable mode using pip install -e . is not currently supported. Developers and users alike should continue to use python conanfile.py installation.
When using senNoiseStd() to set the sensor noise standard deviations in Module: magnetometer and Module: coarseSunSensor the value was being multiplied by 1.5 when creating the diagonal noise matrix. This 1.5x multiplier has now been removed. This is corrected in current release.
SWIG wrapper does not fully support all array types in message payloads. This affects custom message payloads that use these types for array members. Workaround is to add them to swig_conly_data.i.
A bug was fixed in the Module: facetSRPDynamicEffector module. A transpose was required to be added to a dcm in order to correctly express rotated facet normals in the spacecraft body frame.
The MtbEffector.py module was not being imported correctly in Python due to lack of swig_eigen.i include file in MtbEffector.i. This is fixed in the current release, however it remains unknown why the dynamics engine is re-swigged for every individual effector/dynamics related class.
This release uses conan version 2.x which creates a new folder .conan2 in the home folder. Thus, the first time Basilisk is build the project dependencies will be downloaded again into .conan2
If configuring and building Basilisk directly with conan install and build commands, the -if dist3/conan argument is no longer needed. The Basilisk install location is setup with conan 2 arguments inside conanfile.py.

Version 2.5.0

pip-based installation in editable mode using pip install -e . is not currently supported. Developers and users alike should continue to use python conanfile.py installation.
If the simIncludeRW python tool was provided a specific Js value, it was being falsely converted before being assigned. This is now corrected.
If supportData/EphemerisData/de430.bsp is not present the current build system will download the file from JPL server. However, if the download is interrupted, then the next build will find the file and not attempt to re-download it. This is now fixed in the current version where the file is only stored in the supportData folder if the download was complete.
Module: vizInterface was not able to save to a binary data file. This is now fixed in the current release.
Module: vizInterface was not saving the Vizard settings to the binary file. Fixed now.
Installing Basilisk 2.4.0 while packaging<22 is installed can lead to an incompatibility and raise a “TypeError: canonicalize_version() got an unexpected keyword argument strip_trailing_zero” error. Newer versions of Basilisk now upgrade packaging>=22 to solve this issue.
simIncludeRW didn’t allow fCoulomb, fStatic and cViscous to be specified even if a prebuilt RW data set is used. This is corrected in the current release.

Version 2.4.0

The fuel tank models have become classes and python simulation code using tank modules need to be updated. See Module: fuelTank or scenarioFuelSlosh for further documentation.
The CI test builds starting failing running the gtest unit test suite with the error CMake Error: Unknown argument: --gtest_output. The current release fixes this issue.
There was an issue with the Module: thrusterStateEffector such that its mass depletion rate was hard-coded to 100% for all firings. This is corrected in the current release.
pip-based installation in editable mode using pip install -e . is not currently supported. Developers and users alike should continue to use python conanfile.py installation.
The CI test builds starting failing running the gtest unit test suite with the error CMake Error: Unknown argument: --gtest_output. The current release fixes this issue.
If the simIncludeRW python tool was provided a specific Js value, it was being falsely converted before being assigned.

Version 2.3.0

A bug was introduced at 2.2.1 (2dc0a35) to the SimulationBaseClass AddModelToTask function when it was refactored to use the updated module variable logging. The bug manifests as no data being logged for a variable when there are more than one task, a module in each task, and the variable being logged is from a module assigned to a task added to a process after the first task has been added to a process.
Doing a clean build on Windows appeared to complete, but when running python simulation scripts, errors came up about not finding Basilisk packages. The python version number checking on Windows had an issue that is now corrected in the current build.
swig 4.2 was causing run-time errors with Basilisk. The latest version of Basilisk now added support for this version of swig.
Basilisk no longer builds on Windows with the opNav flag turned on. The opencv related conan settings are updated in the current release to address this.

Version 2.2.1

There was an issue with Module: thrusterStateEffector where if there are multiple instances of the thruster state effector then the last effector will over-write all the state of the earlier thrusters. This is corrected in the current release.
Doing a clean Basilisk build with opNav flag on fails building openCV. The conan install script is updated this is corrected in the current release.
We found a slow memory leak if messages with arrays or vectors were accessed from python. The swig issue has now been fixed in the current release.
The Module: facetSRPDynamicEffector module was double counting a cosine term in the SRP force calculation. This is corrected in the current release.
The Module: facetDragDynamicEffector module was missing a negative sign in the drag torque calculation. This is corrected in the current release.

Version 2.2.0

VizInterface has been updated to use 4.5.0 version of ZMQ library. Be sure to use Vizard 2.1.5 or newer.

Version 2.1.7

The way to include effector bodies in Vizard has changed in this release.
The streaming between vizInterface and Vizard was not reliable because of a ZMQ compatibility issue between the two code bases. BSK is reverting to using ZMQ 4.3.0 for now to avoid this issue.
Building Basilisk with opNav mode was no longer working as a conan package dependency issue came up. This has been corrected in the new version by specifying xz_utils/5.4.0 in conanfile.py. Note that building with opNav now also appears to require conan>=1.59.0, but less than 2.0.0.

Version 2.1.6

in Module: boreAngCalc, the variable boreVecPoint is now called boreVec_Po.

Version 2.1.5

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
Module: hingedRigidBodyStateEffector and Module: dualHingedRigidBodyStateEffector module inertial state outputs are relative to the central gravity body, not the inertial frame. This is now corrected.
Adding an instrument camera to Module: vizInterface has changed. See BSK Scripting Settings on how to use the new method addCamMsgToModule().

Version 2.1.4

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
prior version had a bug in computer the latitude in PCPF2LLA() inside geodeticConversion. This is used in the specifyLocationPCPF() method inside Module: groundLocation, and in Module: msisAtmosphere and Module: albedo.
Module: coarseSunSensor now receives in sensorList a list of CSS configuration state pointers, not a copy to the configuration structures. This allows these values to be changed on the fly from within python. However, the simulation code must ensure that the CSS configuration structures are retained in memory or a segmentation fault will ensue.
How stand alone C-wrapped message objects are created in python has moved from cMsgCInterfacePy to messaging. Old scripts still using cMsgCInterfacePy still work as a link has been created to messaging. But, the use of cMsgCInterfacePy is no depreciated and code should be updated to using messaging instead.
The use of custom message in the external modules folders is broke with the new build modification in this release. This is fixed in the latest release.

Version 2.1.3

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
Module: planetEphemeris was not computing the correct orientation, this is fixed in current release
updated examples/OpNavScenarios/BSK_OpNav.py path to the Vizard binary. If you are calling Vizard 2.1+ from the python script, the Vizard binary name changed from Basilisk Vizard` to simply ``Vizard.
using newer versions of Python, such as 3.9.13 or 3.10.5, running conanfile.py runs into errors and fails. This is now addressed in the next release. Upgrading pip to the newest version manually can resolve this issue as well.

Version 2.1.2

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
conan version 1.44 is causing build issues because the way the source and build folders are set has changed. This is fixed in current version of Basilisk.
building Basilisk from scratch with opNav turned on was failing because conan was not able to install opencv/4.1.1. In particular, the package jasper was now failing as a required argument is no longer supported. This is fixed in the current release by turning off this jasper requirement.

Version 2.1.1

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
On windows when building with opNav mode on, the gettext library was not included with the conan software unless the version is 0.21, not 0.20.1. This dependency has been upgraded. This might require deleting the .conan folder in your home directory and re-installing all dependencies.

Version 2.1.0

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found when opNav is included. The code compiles, but auto-completion etc. doesn’t work in that module.
conan changed the default repos in version 1.40 onwards which broke the Basilisk installation. This is now corrected in the latest release. After pulling the latest code release, you’ll need to delete the .conan folder in your home directory to create a fresh copy. This only has to be done once.
Module: spacecraftReconfig has been changed to read in the spacecraft mass from an input message, not be set as a module variable

Version 2.0.7

In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found. The code compiles, but auto-completion etc. doesn’t work in that module.

Version 1.8.1

When deleting .conan and doing a build with opNav set to true, the required dependencies can’t be found on the repo on the first install run. Running it again makes it work. This is fixed in the next release to run properly on the first try.
If openCV is conan installed for Release only the Xcode would give false error messages that it can’t find the library. This is now fixed in the current release.
In Xcode, when editing vizInterface.c/h files, the protobuffer library is not properly found. The code compiles, but auto-completion etc. doesn’t work in that module.
On Linux and Windows the vizInterface and all opNav related modules is not properly linking. Thus, all associated modules, including saving to Vizard binaries, is not working in this version.

Version 1.8.0

The new conan based built system might need the conan cache folder .conan to be deleted and reset. This is typically in the user’s home folder. After this you need to re-run the conan setup commands:
```
$ conan remote add conan-community https://api.bintray.com/conan/conan-community/conan
$ conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
```
If running Windows the path to the Basilisk library destination folder must be set, see Setup On Windows.
On Linux and Windows the vizInterface and all opNav related modules is not properly linking. Thus, all associated modules, including saving to Vizard binaries, is not working in this version.
If running Windows, be sure to use pip install conan to get conan, and don’t download the binary installer, see Setup On Windows. The binary installer causes several issues with this new build system in that it contains its own copy of Python, and thus checking for required python packages does work.
The new build system provides many speed improvements in doing a clean or partial build, but some small changes are required to update BSK python simulation scripts to be compatible with the new build system. These changes include:
- In BSK python simulation scripts, BSK modules should be included using the indirect method. Thus:
```
from Basilisk.fswAlgorithms.cModuleTemplate import cModuleTemplate
```
  becomes:
```
from Basilisk.fswAlgorithms import cModuleTemplate
```
- The pyswice package is now imported from topLevelModule. Thus:
```
from Basilisk import pyswice
```
  becomes:
```
from Basilisk.topLevelModules import pyswice
```
- The support file pyswice_ck_utilities.py has become a regular suppoort file in src/utiliites. Thus, it is imported using:
```
import Basilisk.pyswice.pyswice_ck_utilities
```
- Similarly, pyswice_spk_utilities.py has moved to the utilities folder. To include spkRead function replace:
```
from Basilisk.pyswice.pyswice_spk_utilities import spkRead
```
  with:
```
from Basilisk.utilities.pyswice_spk_utilities import spkRead
```
- To include loadGravFromFileToList function replace:
```
from Basilisk.simulation.gravityEffector.gravCoeffOps import loadGravFromFileToList
```
  with:
```
from Basilisk.simulation.gravityEffector import loadGravFromFileToList
```
If you have written custom BSK modules outside of the BSK distribution, the swig *.i files and some code files will need to be adjusted as follows:
- To include the swig_common_model.i file, replace:
```
%include "swig_common_model.i"
```
  with:
```
%pythoncode %{
from Basilisk.simulation.swig_common_model import *
%}
```
- If Eigen variables are being swig’d, then import:
```
%include "swig_eigen.i"
```
- To swig C arrays of variables, then import:
```
%include "swig_conly_data.i"
```
- To provide support of C++ std::string types, then import:
```
%include "std_string.i"
```
- To provide support of C++ std::vector class, then import:
```
%include "std_vector.i"
```
The files in _GeneralModuleFiles folders are now built into a separate library with the parent folders name plus Lib. This means in the IDE like Xcode and Visual Studio the code in _GeneralModuleFiles is shown in a folder with this library name. Thus, for example, code in src/simulation/environment/_GeneralModuleFiles are shown in the IDE folder environmentLib within the environment parent folder. This keeps the BSK folders cleaner and with less duplicated code being displayed.
A new python package dependency is Pillow. This is needed for the test scripts for Module: camera to run.
In Xcode the build will complain that it can’t find the <Eigen/Dense> library. The code compiles ok. The work around this conan issue is to run the build twice, once for Debug and once for Release. At that point it can be run just once.

Version 1.7.5

Module: groundLocation was not converting between the planet and inertial frame correctly. This is now fixed in the later releases.

Version 1.7.4

None

Version 1.5.1

WINDOWS ONLY: Windows users cannot currently run pytest directly on Basilisk src/ directory (there will be non-resolved python path issues that will result in erroneous ImportErrors). Instead, to verify proper installation of Basilisk, windows users must enter the specific subdirectory they are attempting to test, only then to run pytest. This should result in appropriate behavior. Right now there is no known solution to this issue.

Here the reaction wheel dynamics have been modified such that the RW state output message is no longer hard-coded to rw_config_0_data, etc. Rather, now the ModelTag string is pre-pended to make this output msg name unique with. Any scripts that is logging this RW state message will have to be updated. The reason for this change is to allow multiple spacecraft to have RW devices and unique RW state messages.
There was an issue doing a clean compile using Python 2 which is addressed in the next version
test_reactionWheelStateEffector_integrated didn’t run on Python 2, this is fixed in the next version.

Version 0.4.1

WINDOWS ONLY: Windows users cannot currently run pytest directly on Basilisk src/ directory (there will be non-resolved python path issues that will result in erroneous ImportErrors). Instead, to verify proper installation of Basilisk, windows users must enter the specific subdirectory they are attempting to test, only then to run pytest. This should result in appropriate behavior. Right now there is no known solution to this issue.
The numpy python package can’t be the current version 1.16.x as this causes some incompatibilities and massive amounts of depreciated warnings. These warnings are not related to BSK python code, but other support code. Thus, for now be sure to install version 1.15.14 of numpy.

Version 4.x.x and higher of pytest works again with Basilisk. You are free to install the latest version of pytest.
As we are now using the conan package management system, you can’t double the the Cmake GUI application. Instead, you must either launch the Cmake GUI application from the command line, or run CMake from the command line directly. See the platform specific Basilisk installation instructions.

The latest version of pytest (version 3.7.1) has a conflict with the RadiationPressure module unit test. We are still investigating. In the meantime, using pytest version 3.6.1 is working correctly.
