Travis-CI: Build Status

Core Flight System : Framework : Core Flight Executive

This repository contains NASA's Core Flight Executive (cFE), which is a framework component of the Core Flight System.

This is a collection of services and associated framework to be located in the cfe subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS, which includes build and execution instructions.

The detailed cFE user's guide can be viewed at https://github.com/nasa/cFS/blob/gh-pages/cFE_Users_Guide.pdf.

Version History

Development Build: 6.7.0+dev298

  • Revision version number now reports 99 during development versions. ES Housekeeping data reports 6.7.99 in the version string.
  • See nasa#853

Development Build: 6.7.0+dev292

  • Add missing include path to the target/h and wrn/coreip directory. Set and clarify difference between WIND_HOME and WIND_BASE variables. Remove unrelated comment about CEXP (remnant from RTEMS). No more errors about missing headers.
  • Version reporting is does not span multiple lines.
  • See nasa#792

Development Build: 6.7.0+dev289

  • Update CFE_SB_TimeStampMsg to save the message pointer argument UT_Stub_CopyFromLocal so that unit tests can check it
  • Only affects build system. Fully backward compatible. The defaults are applied if a user has nothing specifically configured in their targets.cmake. The defaults will select osal, cfe-core, and psp as before. The user now has the option to explicitly configure and control the inclusion of these modules and also provide mission-specific search paths to override them as desired.
  • Note this only affects UT stubs. Change the internal names of some stub arguments to match prototype. Ensure that:
    • All functions in the CFE public API have a stub function implemented
    • All parameters to the stub function are registered in the context object, so the values will be available to hook functions.
    • The names of all parameters match the prototype/documentation, so hook functions that use name-based argument value retrieval will work.
  • Adds to table search path in arch_build.cmake
  • Calls to OS_open() now use the OSAL-defined symbol, not the POSIX symbol.
  • Defines new macros to report the build number and build baseline and new strings containing the version number of cFE and a combined string with the version number for OSAL, PSP, and CFE.
  • Allow explicitly setting of the processor ID in targets.cmake. The TGTx_PROCESSOR_ID setting will be passed to the final build/link of CFE core as the CPU ID. If unspecified, then the CMake index value is used instead (backward compatible).
  • cmake now detects conditions where no files were present to fulfill an config include file requirement and reports an error during make prep lists the files it checked for rather than generating an empty file.
  • See nasa#765

Development Build: 6.7.21

  • If a string is exactly the size of the field when using the CFE_TBL_FILEDEF() macro it will produce a compiler error
  • Added cFE User's Guide Reference to README.md
  • Removes old license
  • See nasa#743

Development Build: 6.7.20

  • SB Unit use of the UT assert framework is closer to original design intent
  • See nasa#743

Development Build: 6.7.19

  • API Change: cFE ut_sb_stubs now has CFE_SB_DeletePipe available. Behavior Change: App unit tests requiring this will not fail to build due to undefined reference to CFE_SB_DeletePipe
  • Hook functions may now use the va_list form and obtain the full set of variable arguments passed to CFE_EVS_SendEvent and variants.
  • Replace all direct references to data types defined in ccsds.h with the abstract type defined in cfe_sb.h.
  • See nasa#729 for details.

Development Build: 6.7.18

  • Using ut stubs CFE_EVS_SendEvent and CFE_ES_WriteToSysLog, the register buffer will have the correct size. access to register buffer element will exist
  • Both the main task and the child task(s) are successfully deleted and restarted after the exception occurs.
  • Fixes doxygen warnings for the tbl subsystem.
  • No compiler warnings or errors on cross build.
  • Changes Message Key from uint16 to uint32 to avoid rollover and system hang
  • See nasa#712 for more details

Development Build: 6.7.17

  • No longer automatically decompresses apps/libraries as part of load
  • Deletes now unused CFE_ES_CountObjectCallback and CFE_ES_ListResourcesDebug. Flags were unused
  • Removes all conditional preprocessing blocks related to CFE_ARINC653.
  • Ensure clean build, no warnings on string operations using GCC 9.3.0.
  • When OMIT_DEPRECATED = true attempt to send output to shell command will result in command error counter increment (unrecognized function code)
  • SBN will need to init command with new MID
  • Documentation links and references will now work properly
  • API CFE_ES_ProcessCoreException is removed, replaced with async event.
  • Removed duplicate prototype in cfe_time_utils.h
  • Removes unused defines and adds documentation to TBL event defines.
  • Deprecates CFE_TIME_CFE2FSSeconds and CFE_TIME_FS2CFESeconds.
  • Unit tests now build and run when MESSAGE_FORMAT_IS_CCSDS_VER_2 is configured.
  • Build now works with both extended headers and OMIT_DEPRECATED options set.
  • No more alignment warnings
  • Adds new unit test macros
  • See nasa#692 for more details

Development Build: 6.7.16

  • Users must now select OSAL options via the CMake file in their defs directory, rather than the osconfig.h file.
  • See nasa#672 for more details

Development Build: 6.7.15

  • Upon power on reset, default system log mode set to overwrite. Upon processor reset, default system log mode set to discard.
  • No longer locks while locked (no issue observed on linux/posix, but user reported issue on FreeRTOS 10)
  • Internal CFE_TBL_LoadFromFile() API changed slightly to add AppName as a parameter. Return value from LoadFromFile() no longer relevant for event generation.
  • Updates CFE_TBL_CleanUpApp such that it now checks the 'used flag' prior to calling CFE_TBL_RemoveAccessLink for a given TblHandle. Also sets the AppId to CFE_TBL_NOT_OWNED after removing the access descriptor link from linked list.
  • Removed OS_FS_SUCCESS, OS_FS_ERROR , OS_FS_ERR_INVALID_POINTER, OS_FS_ERR_NO_FREE_FDS , OS_FS_ERR_INVALID_FD, and OS_FS_UNIMPLEMENTED from osapi-os-filesys.h
  • See nasa#649 for more details

Development Build: 6.7.14

  • Exposes the CFE_SB_IsValidMsgId() for application usage.
  • CFE_SB_GetLastSenderID will now detect if it is being called prior to a message being sent on a given pipe.
  • Mismatches between PSP/BSP/OS are now detected and warned about during make prep. Only the CFE_SYSTEM_PSPNAME is actually required to be specified for a CFE build now. Others can be omitted.
  • See nasa#635 for more details

Development Build: 6.7.13

  • RTEMS builds without error.
  • Use the INTERFACE_COMPILE_DEFINITIONS and INTERFACE_INCLUDE_DIRECTORIES properties from the osal target and apply them to the entire CFE build as a directory-scope property. No impact until these are set in OSAL.
  • Minor other updates (see nasa#615)

Development Build: 6.7.12

  • Cmd code (and checksum) are always in the same place (matches GSFC spec for command secondary header)
  • No impact to behavior. Previously the perf log dump file frequently contained errors due to out of order or otherwise corrupted entries, which is now fixed.
  • Minor other updates (see nasa#586)

Development Build: 6.7.11

  • Improve documentation
  • Update makefile to report branch coverage
  • Minor other updates (see nasa#566)

Development Build: 6.7.10

  • Fix potential unit test problems with name collisions
  • Improve documentation
  • Minor other updates (see nasa#563)

  • Minor other updates (see nasa#544)

Development Build: 6.7.8

  • Updates and cleaned up documentation and requirements
  • Fixes incorrect debug messages
  • Decrease child task count when one is deleted
  • Minor other updates (see nasa#530)

Development Build: 6.7.7

  • Adds a new function, CFE_SB_GetPipeIdByName, which retrieves the pipe ID given a name of a pipe.
  • Improvement in error reporting when using a pipe name that is already in use, or when the queue limit has been reached.
  • Added userguide and osalguide to the local target list to avoid makefile warning
  • Minor other updates (see nasa#511)
