Description Ales Zelinka 2013-05-29 11:10:05 EDT
+++ This bug was initially created as a clone of Bug #968300 +++

7 RHEL5 TIP runes were killed by one of these tests, please investigate and fix the culprit as soon as possible. 

Switch both tests to a CONFIRMED state in TCMS once they're no longer destructive.

list of test runs affected by this (see test-run notes for IDs of the killed recipes):
TR#64754, TR#64614, TR#64476, TR#64370, TR#64247, TR#64173, TR#64124

I think, that is very nasty beakerlib implementation...

From documentation:
    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". 

From test:
rlRun -s "grep localhost:/usr /etc/mtab" 0 "Grep content of /etc/mtap"

This command has no output!

Test output:
:: [   FAIL   ] :: File '/dev/null' should contain 'noacl' 

From test:
rlRun "rm -r $rlRun_LOG" 0 "Removing $rlRun_LOG"

Test output:
:: [   PASS   ] :: Removing /dev/null

I wrote little workaround.
But this construction is still very dangerous.

Comment 2 Petr Muller 2013-06-07 07:57:36 EDT
Sorry, got a bit confused. This is not a dup.
Comment 3 Petr Muller 2013-06-07 09:06:15 EDT
It is not a dup, but it is related. /dev/null should never be propagated to rlLog_LOG: when rlLog_LOG is set, it implies that DO_KEEP was set earlier, and that code should create a temporary logfile.

But the check for logfile creation was missing, /dev/null was used instead and was propagated in rlLog_LOG (in some cases rlRun even deleted it itself :)

I have modified rlRun so that /dev/null is only used in basic mode (no removal or propagation). With switches, when the temporary logfile creation fails, it is reported and switched to basic mode.
