# The following logging mechanisms are to be used in bash functions of recipes. # They are intended to map one to one in intention and output format with the # python recipe logging functions of a similar naming convention: bb.plain(), # bb.note(), etc. # # For the time being, all of these print only to the task logs. Future # enhancements may integrate these calls with the bitbake logging # infrastructure, allowing for printing to the console as appropriate. The # interface and intention statements reflect that future goal. Once it is # in place, no changes will be necessary to recipes using these logging # mechanisms. # Print the output exactly as it is passed in. Typically used for output of # tasks that should be seen on the console. Use sparingly. # Output: logs console # NOTE: console output is not currently implemented. bbplain() { echo "$*" } # Notify the user of a noteworthy condition. # Output: logs console # NOTE: console output is not currently implemented. bbnote() { echo "NOTE: $*" } # Print a warning to the log. Warnings are non-fatal, and do not # indicate a build failure. # Output: logs bbwarn() { echo "WARNING: $*" } # Print an error to the log. Errors are non-fatal in that the build can # continue, but they do indicate a build failure. # Output: logs bberror() { echo "ERROR: $*" } # Print a fatal error to the log. Fatal errors indicate build failure # and halt the build, exiting with an error code. # Output: logs bbfatal() { echo "ERROR: $*" exit 1 } # Print debug messages. These are appropriate for progress checkpoint # messages to the logs. Depending on the debug log level, they may also # go to the console. # Output: logs console # Usage: bbdebug 1 "first level debug message" # bbdebug 2 "second level debug message" # NOTE: console output is not currently implemented. bbdebug() { USAGE='Usage: bbdebug [123] "message"' if [ $# -lt 2 ]; then bbfatal "$USAGE" fi # Strip off the debug level and ensure it is an integer DBGLVL=$1; shift if ! [[ "$DBGLVL" =~ ^[0-9]+ ]]; then bbfatal "$USAGE" fi # All debug output is printed to the logs echo "DEBUG: $*" }
