RE: Patch breaks OFED 1.5.3: [ewg] [PATCH] ibdiagpath: Properly index VlArbTable during QoS test
YK,
I just finished running an RC4 build on Redhat 6. I didn't get the same error -
but ibdiagpath still failed:
[root@ifs004 1]# ibdiagpath -l 0x1,0x2

The problem appears to be occurring in this code fragment:
if {[info exists NODE]} {
for {set i 0} {$i < [llength [array names NODE *,PortGUID]]} {incr
i} {
set portGuid $NODE($i,PortGUID)
set nodeGuid $G(data:NodeGuid.$portGuid)
if {$i % 2} {
set portNum $NODE($i,EntryPort)
} else {
set portNum [lindex [split $PATH([expr $i + 1]) ,] end] <<
-- Bug here. Line 2381, ibdebug_if.tcl
}
lappend CSV_ERRORS
$CSV_scope,$nodeGuid,$portGuid,$portNum,$desc,$msgBody,$CSV_severity,$exid,$err_type
}
} else {
lappend CSV_ERRORS
$CSV_scope,$nodeGuid,$portGuid,$portNum,$desc,$msgBody,$CSV_severity,$exid,$err_type
}
}
I don't know if it matters, but I'm testing with a one-port HCA. I added a puts
in the offending code and got this:
MHEINZ: i = 0. PATH(0) = 1
can't read "PATH(1)": no such element in array
Please let me know if there are any tests I can run for you.

Yevgeny,
It did occur to me that this is a version issue; I tested with TCL 8.4, which
is the version included in RHEL5 and SLES10. The newest version appears to be
8.5, skimming through the release notes I didn't see anything about languages
changes, but if it's working for you then obviously the language has been
changed.
The thing is, I also noticed that John's original complaint - about an extra
item in the array - did not seem to be true on the RHEL 5.x boxes I tried,
which is why I suggested that the entire change should be rolled back.
I'm building RC4 on a Red Hat 6 box now, I'll see if it makes a difference.

Mike,
This looks like a different tcl versions/implementation issue.
I certainly can replace "$i+1" with "[expr $i+1]", but I'm not
sure about reverting the patch.
John,
What tcl version have you used?

Patch breaks OFED 1.5.3: [ewg] [PATCH] ibdiagpath: Properly index VlArbTable during QoS test
The version of ibdiagpath included with OFED 1.5.3-rc3 contains syntax errors which prevent it from executing on the systems I've tested (using TCL 8.4). Attempts to use ibdiagpath fail with an error message: > -I--- > -I- QoS on Path Check > -I--- > bad index "0+1": must be integer or end?-integer? After doing some research and debugging, I traced the problem to a patch applied back in October: commit f3cf1f7c15ca24598fdf68b9ba71788b386b2f14 Author: John Jolly Date: Wed Oct 6 17:29:48 2010 +0200 ibdiagpath: Properly index VlArbTable during QoS test Description: ibdiagpath: Properly index VlArbTable during QoS test Symptom: Error 'invalid bareword "vl_entry"' during "QoS on Path Check" Problem: The 'dump' command within the smVlArbTableMad command appends '-vl_entry' to the beginning of the array. The ibdebug.tcl script does not properly handle this extra element at the beginning of the array. Solution:Offset the index value by one when referencing the array. Signed-off-by: John Jolly Signed-off-by: Yevgeny Kliteynik Unfortunately, this patch isn't valid TCL code (at least not in TCL 8.4) and does not appear to be needed at all. For example: > set entry [lindex $values $i+1] Is not syntactically correct TCL. In order for it to be correct it would have to be > set entry [lindex $values [expr $i+1]] However, the patch does not appear to be needed at all.
