10.2 Development Release Series 8.5

This is the development release series of HTCondor. The details of each version are described below.

Version 8.5.1

Release Notes:

• HTCondor version 8.5.1 released on December 21, 2015.

• Shared port is enabled by default. (Ticket #3813). (Ticket #5103).

New Features:

• The condor_startd history file now contains the peak memory usage, by an exited job, not the more recent. (Ticket #5436).

• When the condor_starter evicts a job, perhaps because it has exceeded a memory limit, it does not transfer back to the submit machine the sandbox of working files. This is consistent with other types of holds. (Ticket #5437).

• The condor_startd now advertises the following attributes on Linux machines: CpuFamily CpuModelNumber CacheSize. These are pulled from the /proc/cpuinfo file. (Ticket #5323).

• condor_q has a new option -schedd-constraint which can be used to constrain the queues displayed when using the -global option. (Ticket #5043).

• When an HTCondor-C job is submitted to a remote condor_schedd, the remote job ad now includes the attribute SubmitterGlobalJobId, whose value is the same as the attribute GlobalJobId in the original HTCondor-C job. (Ticket #3472).

• The condor_schedd now sets environment variables for scheduler universe jobs so that the jobs can more easily find the condor_schedd's contact information. On machines where there are multiple condor_schedds running, this helps DAGMan and similar applications contact the condor_schedd that started them. (Ticket #5166).

• When SEC_ENABLE_MATCH_PASSWORD_AUTHENTICATION is set to True, the related authorizations are now automatically enabled. Previously, submit-side@matchsession and execute-side@matchsession entries had to be added to the ALLOW_DAEMON and ALLOW_CLIENT (if set) authorization parameters in order for this feature to work. (Ticket #5304).

Bugs Fixed:

• condor_history run on a pool with partitionable slots now shows the correct dynamic slot. (Ticket #4261).

Version 8.5.0

Release Notes:

• HTCondor version 8.5.0 released on October 12, 2015.

New Features:

• The condor_startd history file contains two new attributes: BadputCausedByDraining and BadputCausedByPreemption, two boolean-valued attributes which are true if the job was evicted not by a user request. (Ticket #5255).

• The python bindings have a new Claim API, allowing Computing-On-Demand (COD) to be invoked via python. (Ticket #5130).

• The python bindings can now submit multiple distinct processes using the submitMany method, similar to a condor_submit file with multiple queue statements. (Ticket #4916).

• The python bindings now provide improved support for managing multiple concurrent queries. (Ticket #5187).

• As an experimental feature, the python bindings implement the HTCondor negotiation protocol. (Ticket #5125).

• Changed "Condor" to "HTCondor" in condor_dagman output (mainly in the dagman.out file). (Ticket #5144).

• The new configuration parameter JOB_SPOOL_PERMISSIONS controls the permissions on a job's spool directory managed by the condor_schedd on unix. It defaults to the value user, which results in a permissions value of 0700. Other valid values are group (permissions 0750) and world (permissions 0755). Previously, all job spool directories had access permissions of 0755. (Ticket #4896).

• The condor_schedd no longer changes the ownership of spooled job files that it manages. Now, the files are always owned by the submitting user. The previous behavior of changing ownership to/from the condor account can be restored by setting the new configuration parameter CHOWN_JOB_SPOOL_FILES to True. (Ticket #5226).

Bugs Fixed:

• None.
