A new 6.2.4 maintenance release is now available for the Qube 6.2 Core/Supervisor/Worker. This is a recommended release for all customers running Qube v6.2.

Please note that v6.2.3 was never actually released, but that all changes, fixes, etc from 6.2.3 are present in 6.2.4

Below is a list of the fixes and enhancements since the last point-release.


@RELEASE: 6.2.4

ZD: 5749

==== CL 9310 ====
@FIX: add mail template for auto-wrangling emails to the installers

@RELEASE: 6.2.3

==== CL 9265 ====

ZD: 5609

==== CL 9261 ====
@CHANGE: cut down on the cmdline & cmdrange jobtypes' stdout; don't print 'LOG: ...' lines, make regex summaries much clearer, change printing or regex's to stderr to make it clearer that they're not actual errors, but rather things being searched for in the stderr stream.

==== CL 9252 ====
@FIX: properly find qb.conf on Windows versions Vista and later when unable to contact the supervisor directly.

==== CL 9245 ====
@FIX: GUI changes to be able to handle when supervisor host goes down, and both supervisor and MySQL server are unavailable.  Also fix jobList not refreshing on down supervisor.

==== CL 9241 ====
@FIX: fix GUI crashbug in MySQLConnect when supervisor does not answer a

==== CL 9232 ====
@FIX: fixed example python code ( to work on Windows too.

==== CL 9211 ====
@FIX: added code to prevent the QbQueue::getSubjobReadyfindReady() routine from returning the same subjob to be dispatched over and over.

This was causing the findSubjobAndReserveJob() and startJob() routines to
hit the "subjob [N] seems to be already assigned" situation, and cause
threads to enter a long, sometimes semi-infinite, sleep-and-retry loop.

Fixed by adding code in the startJob() routine to quickly update the subjob
status when the the assignJob() returns QB_ASSIGN_OK (i.e., worker says it
has accepted the subjob), instead of waiting until the worker later reports
that the subjob is "running" via the STATUS_JOB message, which can take
more than several seconds on a busy farm.

Also reduced the number of maximum retries to 3 (MAX_ATTEMPTS), in the
situations where a subjob "seems to be already assigned" or when a worker
host says it's busy (QB_ASSIGN_BUSY). This prevents the threads to get
stuck for 10 or more seconds in a sleep-retry loop, and allow them to give
up quickly and move on.
