How to know who recommended a ClearCase baseline? - clearcase

Question

Somebody recommended a baseline in my stream. How do I know how recommend it? I can only see who created it but didn't get any info who recommend it. Is there any specific command to see the history of the baseline/stream/view etc?

I don't think that meta-data is recorded.
You can check for the policies attached to the UCM project though
POLICY_CHSTREAM_UNRESTRICTED
If it is not set, that means only the owner of the UCM project can change the recommended baseline on a stream.
Otherwise, as suggested below, you would need to catch and record that event yourself through trigger.
At the area of ClearCase 7.x (thos could have changed with CC8), this was done with a pre-op trigger on chstream, but it had to deal with two kind of interactions:
CLI (cleartool chstream -recommended)
GUI (through the "recommend baseline" contextual menu)
See for instance this thread:
recommend_bls trigger, with an early out check if chstream was not for a recommend baseline:
if ($ENV{CLEARCASE_CMDLINE}) {
# chstream run from the command line, check for a "-recommended" option
if ($ENV{CLEARCASE_CMDLINE} =~ /-recommend /) {
$msg->D( "this is a chstream to recommend a baseline",
"CLEARCASE_CMDLINE is: <$ENV{CLEARCASE_CMDLINE}>",
"trigger proceeding...",
);
}
else {
$msg->D( "EARLY OUT - this chstream command does not include a
baseline recommend:",
"CLEARCASE_CMDLINE is: <$ENV{CLEARCASE_CMDLINE}>",
);
exit 1;
}
}
else {
# chstream was run from the gui, must look at event records to
# determine if the command was a baseline recommend or
# some other change to the stream
my $lshist_rc = qx($CT lshist -minor -last 1 -me stream:$ENV{CLEARCASE_STREAM});
if ($?) {
# error in the lshist command, report trigger error
my #args = ("$CP proceed -type error -default abort -mask abort -newline -prompt \"***RECOMMEND_BL Trigger Version: $VERSION***\n\n<lshist> cmd failed on
stream:$ENV{CLEARCASE_STREAM}.\nResults:\n$lshist_rc\nPlease send a
screen print of this error to your ClearCase admin.\" -prefer_gui");
system (#args);
$msg->D( "Processing aborted - lshist command failed!",
"$lshist_rc"
);
exit 11;
}
chomp($lshist_rc);
# check latest stream event record to see if the chstream was
# a baseline recommend or some other change to the stream.
# a baseline recommend will have an event record of the form:
# "Set activity process variable named "UCM_STREAM_RECBLS".
if ($lshist_rc =~ /UCM_STREAM_RECBLS/) {
$msg->D( "this is a chstream to recommend a baseline",
"latest event record on stream is:",
"$lshist_rc",
"trigger proceeding...",
);
}
else {
$msg->D( "EARLY OUT - this chstream command did not include a baseline recommend:",
"latest event record on stream is:",
"$lshist_rc",
);
exit 1;
}
}
