rlRun

Run command with optional comment and make sure its exit code matches expectations.

    rlRun [-t] [-l] [-c] [-s] command [status[,status...] [comment]]

-t

If specified, stdout and stderr of the command output will be tagged with strigs 'STDOUT: ' and 'STDERR: '.

-l

If specified, output of the command (tagged, if -t was specified) is logged using rlLog function. This is intended for short outputs, and therefore only last 50 lines are logged this way. Longer outputs should be analysed separately, or uploaded via rlFileSubmit or rlBundleLogs.

-c

Same as -l, but only log the commands output if it failed.

-s

Store stdout and stderr to a file (mixed together, as the user would see it on a terminal) and set $rlRun_LOG variable to name of the file. Caller is responsible for removing the file. When -t option is used, the content of the file becomes tagged too.

If the -s option is not used, $rlRun_LOG is not modified and keeps its content from the last “rlRun -s”.

command

Command to run.

status

Expected exit code(s). Optional, default 0. If you expect more exit codes, separate them with comma (e.g. “0,1” when both 0 and 1 are OK and expected), or use from-to notation (i.e. “2-5” for “2,3,4,5”), or combine them (e.g. “2-4,26” for “2,3,4,26”).

comment

Short summary describing the action (optional, but recommended - explain what are you doing here).

Returns the exit code of the command run. Asserts PASS when command\'s exit status is in the list of expected exit codes.

Note:

• The output of rlRun is buffered when using -t, -l or -s option (they use unix pipes, which are buffered by nature). If you need an unbuffered output just make sure that expect package is installed on your system (its “unbuffer” tool will automatically be used to produce unbuffered output).
• Be aware that there are some variables which can collide with your code executed within rlRun. You should avoid using __INTERNAL_rlRun_* variables.

• When any of -t -l, -c, or -s option is used, special file descriptors 111 and 112 are used to avoid the issue with incomplete log file, bz1361246. As there might be an indefinite loop, there's a timeout of two minutes implemented as a fix for bz1416796. Also an error message is issued to signal the possibility of running subprocess which keeps the file descriptors open.

  Do not use these options if you expect process forking and continuouse run. Try your own apropriate solution instead.

Warning: using unbuffer tool is now disabled because of bug 547686.

rlWatchdog

Run command. If it does not finish in specified time, then kill it using signal.

    rlWatchdog command timeout [signal] [callback]

command

Command to run.

timeout

Timeout to wait, in seconds.

signal

Signal to use (optional, default KILL).

callback

Callback function to be called before the signal is send (optional, none by default). The callback function will have one argument available — PGID of the process group.

Returns 0 if the command ends normally, without need to be killed.

rlReport

Report test result to the test harness. The command to be used for reporting is set by the respective plugin. You can also use the $BEAKERLIB_COMMAND_REPORT_RESULT variable to use your custom command.

    rlReport name result [score] [log]

name

Name of the test result.

result

Result (one of PASS, WARN, FAIL). If called with something else, will use WARN.

score

Test score (optional).

log

Optional log file to be submitted instead of default OUTPUTFILE.

rlCmpVersion

Compare two given versions composed by numbers and letters divided by dot (.), underscore (_), or dash (-).

    rlCmpVersion ver1 ver2

If ver1 = ver2, sign '=' is printed to stdout and 0 is returned. If ver1 > ver2, sign '>' is printed to stdout and 1 is returned. If ver1 < ver2, sign '<' is printed to stdout and 2 is returned.

rlTestVersion

Test releation between two given versions based on given operator.

    rlTestVersion ver1 op ver2

op

Operator defining the logical expression. It can be '=', '==', '!=', '<', '<=', '=<', '>', '>=', or '=>'.

Returns 0 if the expresison ver1 op ver2 is true; 1 if the expression is false and 2 if something went wrong.

rlIsRHEL

    rlIsRHEL [Num|opNum]

Num

When used function returns 0 if the particular RHEL version is running. Multiple arguments can be passed separated with space as well as any particular release (5.1 5.2 5.3).

opNum

Argument consisting of operator and number written together as one string. Operator can be '<', '<=', '=<', '=', '>', '>=' matching whether the currently installed version is lesser, lesser or equal, equal, equal or greater, greater than the version number supplied as second half of the argument. Note that ie. '=5' (unlike just '5') matches exactly 5 (5.0), not 5.N, where N > 0. Also note when that using >/< operators you have to either put the argument in quotes or escape the operators to avoid them being interpreted as bash redirection operator.

Returns 0 when we're running on RHEL.

Note that

    rlIsRHEL '<6.9' || rlIsRHEL '<7.5'

would also cover 6.10 as it is less than 7.5, which is not what you want. So if you want to construct a condition for rhel<6.9 for rhel6 or rhel<7.5 for rhel7 you actually need to use following construct:

    rlIsRHEL 6 && rlIsRHEL '<6.9' || rlIsRHEL 7 && rlIsRHEL '<7.5'

Prototype:

    rlIsRHEL

Returns 0 if we are running on RHEL.

    rlIsRHEL 4.8 5

Returns 0 if we are running RHEL 4.8 or any RHEL 5.

    rlIsRHEL ">=6" or rlIsRHEL \>=6

Returns 0 if we are running RHEL 6 or higher.

rlIsFedora

    rlIsFedora [Num|opNum]

Returns 0 when we're running on Fedora. With given number of version as parameter returns 0 if the particular Fedora version is running. Range matching can be used in the form used by rlIsRHEL.

    rlIsFedora

Returns 0 if we are running on Fedora.

    rlIsFedora 9 10

Returns 0 if we are running Fedora 9 or 10.

rlIsCentOS

    rlIsCentOS [Num|opNum]

Returns 0 when we're running on CentOS. With given number of version as parameter returns 0 if the particular CentOS version is running. Range matching can be used in the form used by rlIsRHEL.

    rlIsCentOS

Returns 0 if we are running on CentOS.

    rlIsCentOS 7.1 6

Returns 0 if we are running CentOS 7.1 or any CentOS 6.
