10.3 Stable Release Series 8.2

This is a stable release series of HTCondor. As usual, only bug fixes (and potentially, ports to new platforms) will be provided in future 8.2.x releases. New features will be added in the 8.3.x development series.

The details of each version are described below.

Version 8.2.10

Release Notes:

HTCondor version 8.2.10 released on October 22, 2015.

New Features:

None.

Bugs Fixed:

Fixed a bug that prevented the condor_negotiator from preempting jobs based on user priority when ALLOW_PSLOT_PREEMPTION was set to True. (Ticket #5236).
Added post install rules to the Enterprise Linux 7 RPM to configure SELinux for HTCondor operation. HTCondor works with SELinux in a default HTCondor configuration. Advanced HTCondor configurations using cgroups do not yet work with SELinux. (Ticket #5012).
Fixed bugs that prevented the condor_kbdd from authenticating to the X server, and thus from correctly reporting when the keyboard or mouse were in use. (Ticket #5264).
The condor_kbdd now works with shared port enabled. (Ticket #5239).
Fixed a bug that caused HTCondor daemons to crash when using more than 1024 file descriptors on Enterprise Linux 7 systems. (Ticket #5240).
Fixed a memory leak when the ClassAd function split() is used. (Ticket #5219).
condor_vacate will now fail with an error message when the -constraint argument is used more than once or used with other arguments that cannot be handled while processing the constraint. Earlier versions would just quietly ignore all but the last constraint. (Ticket #5234).
Fixed a bug that could cause the Job Router to not see the current job queue state when it restarts. This could result in routed jobs experiencing file permissions errors and the submission of two routed jobs for a single source job. (Ticket #5270).
Fixed a bug that could cause spurious data to be sent in a SOAP file transfer. (Ticket #5320).
Fixed a bug that caused condor_history to return jobs out of order when there were more than 2 history files. (Ticket #5305).

Version 8.2.9

Release Notes:

HTCondor version 8.2.9 released on August 13, 2015.

New Features:

A new matchmaking mode permits one or more dynamic slots to be preempted in order to make enough resources available to their parent partitionable slot to allow a job match. The new mode is enabled by setting the new configuration variable ALLOW_PSLOT_PREEMPTION to True. This variable defaults to False. (Ticket #5097).
When a scheduler universe job exits, the condor_schedd now kills any child processes that the job left behind. (Ticket #5173).

Bugs Fixed:

Configuration variables START and SLOTS_CONNECTED_TO_KEYBOARD are now included in the setting of the desktop policy metaknobs. (Ticket #5196).
Fixed a bug in the Windows installer. It did not correctly set the configuration for the case in which the user requested that jobs only run when the keyboard is idle. (Ticket #5197).
Fixed a bug that resulted in HTCondor possibly not detecting all of the CPU cores on Windows, when the number of cores was large. The bug was first seen on a server with 24 real cores (48 Hyper-threaded cores). (Ticket #5075).
Fixed a bug that would cause the quantity of run time reported for grid universe jobs with grid type condor to be double the actual value. (Ticket #329). (Ticket #5007).
Fixed a bug that caused the condor_starter to hang for a long period of time when the transfer of output files fails. (Ticket #5121).
Fixed a bug in which Linux kernel version 4 would incorrectly report a load average of -1. (Ticket #5080).
Fixed a bug that would prevent attributes set by condor_chirp set_job_attr_delayed from being sent back to the condor_shadow or condor_schedd. Also fixed a bug that would cause all use of this condor_chirp command to fail once 50 unique ClassAd attribute names had been set. (Ticket #5050).
Fixed a bug that caused job errors upon restart of the Job Router. (Ticket #5181).
Improved the performance of the condor_c-gahp by using lightweight polling. (Ticket #5190).
Fixed a bug that caused condor_status -submitters -wide to truncate the submitter names within the second part of the output. (Ticket #5087).
Using condor_status -long with the -attributes option now fetches from the condor_collector and then displays the attributes specified along with any attributes that they, in turn, reference. Additional attributes already being sent may be included. (Ticket #5160).
Fixed a bug in which the condor_gangliad aggregation functions min() and max() produced incorrect results. (Ticket #5015).
Added PYTHONPATH to the list of environment variables set in the scripts generated by condor_configure, to make the HTCondor Python bindings automatically available. (Ticket #4993).
Fixed a bug that could cause GSI authentication or X.509 proxy delegation to fail with an error message of "couldn't set globus thread model". (Ticket #5061).
The release tag in the RPM packaging is now set to 1 upon release. Previously, it was set to the build ID, which violated the RPM Packaging Guidelines. (Ticket #5042).
Fixed a problem in the Red Hat Enterprise Linux 7 RPM packages that prevented the Java universe from operating. The global configuration file is now updated in the RPM packages to properly refer to the support files for the Java universe. (Ticket #5059).
Files omitted from the new style RPM packages for Red Hat Enterprise Linux 7 are now present. They include the condor_credd binary, the condor_set_shutdown binary, the condor_set_shutdown manual page, and the condor_vm-gahp-vmware binary. (Ticket #5098).
Corrected the definition of the job ClassAd attribute GlobalJobId within the HTCondor manual. (Ticket #5096).
On Windows platforms, fixed an incorrect Win32 default value for configuration variable DAGMAN_CONDOR_RM_EXE. The incorrect default caused condor_dagman to not correctly remove running node jobs, if the ABORT-DAG-ON feature was triggered. (Ticket #5114).
Restrictions on allowable concurrency limit names are now enforced. Previously, the names were allowed to have unexpected characters, which would cause the condor_userprio command to fail. (Ticket #5123).
The condor_schedd now properly updates badput statistics when it kills an unresponsive condor_shadow process. (Ticket #5151).
When a daemon or tool wants to avoid all available condor_collector daemons due to previous failures, it will now try to talk to one. Previously, it would return failure without any attempt to contact a condor_collector daemon. (Ticket #4895).

Version 8.2.8

Release Notes:

HTCondor version 8.2.8 released on April 7, 2015.

New Features:

None.

Bugs Fixed:

Fixed a bug that could cause updates sent to the host defined by CONDOR_VIEW_HOST to fail once the HTCondorView collector is restarted, if the updates are being sent via TCP. (Ticket #4915).
Fixed a bug that could have caused the condor_schedd to start more jobs than specified by the value of configuration variable MAX_JOBS_RUNNING, and then later kill the excess running jobs. (Ticket #4554).
Fixed a bug in which HTCondor was looking for configuration variable IsOwner, instead of IS_OWNER. Now, the system permits specification of either spelling, and IsOwner takes precedence. (Ticket #4949).
Fixed a bug that could cause the condor_schedd to crash when removing jobs that were in the process of being submitted using condor_submit with a -spool or -remote command line option. (Ticket #4866).
Fixed a minor bug that would emit a grep not found warning when using condor_ssh_to_job to log in to a MacOS execute node. (Ticket #4789).
Fixed problems running a central manager on a Windows operating system that could prevent the condor_collector from being restarted, and/or could cause delays when shutting down the HTCondor service. (Ticket #4923).
Fixed bugs in ClassAds and the Python bindings with handling Daylight Saving Time when using timestamp values. (Ticket #4936). (Ticket #4937).
Upon reboot of a submit machine, fixed a bug that would prevent successful reconnection with a previously running job using streaming I/O via submit file options stream_output or stream_error. (Ticket #4939).
If CONSUMPTION_POLICY is enabled for a partitionable slot, then CLAIM_PARTITIONABLE_LEFTOVERS will be treated as False for that slot. This avoids a problem, because claims using a consumption policy and the use of CLAIM_PARTITIONABLE_LEFTOVERS conflict with each other. (Ticket #4950).
Fixed a bug that could have caused a partitionable slot to remain in the Matched state forever when configuration variables CONSUMPTION_POLICY and NEGOTIATOR_INFORM_STARTD were both set to True. (Ticket #4945).
Updated the Globus GRAM library to allow the TLS encryption standard to be used, instead of always using the old SSLv3 standard. (Ticket #4964).
Fixed the condor_schedd daemon's default value for configuration variable MAX_JOBS_RUNNING, when the variable is cleared in the configuration file. The default value was ten times too large. The default value could also become negative on a machine with a large amount of memory (over 500 GiB). (Ticket #4966).
For DAGMan-related configuration, added missing entries to the default parameter table and documentation, and removed obsolete parameters from the default parameter table. (Ticket #4826).
Fixed a bug in condor_who that, when processing the -daemons command line option, prevented it from detecting that the condor_shared_port or condor_job_router daemons had exited. (Ticket #4962).
Fixed a bug that could cause the cream_gahp to fail at start up, if an incompatible version of the Globus libraries were installed. (Ticket #4865).
Fixed a bug that could cause grid universe jobs of grid type lsf to fail when attempting to submit to LSF. (Ticket #4938).

Version 8.2.7

Release Notes:

HTCondor version 8.2.7 released on Feb. 10, 2015.
Security Item: The default mailer has been switched to sendmail, because HTCondor's interactions with mailx could lead to privilege escalation. The CVE is described at https://access.redhat.com/security/cve/CVE-2014-8126. (Ticket #4878).

New Features:

None.

Bugs Fixed:

Grid universe jobs with the grid type gce now work with the current version of Google Compute Engine (GCE). (Ticket #4586).
Improved the cleanup of Google Compute Engine (GCE) instances that are terminated. (Ticket #4832).
Fixed a usability problem with EC2 grid universe jobs. HTCondor now ignores trailing white space characters within the files identified by submit commands ec2_access_key_id and ec2_secret_access_key. (Ticket #4791).
Fixed a race condition that prevented jobs from being held when the job went over its memory allocation. On hosts where memory.use_hierarchy was set to 1 in the memory cgroup controller, jobs would frequently receive the SIGKILL signal or be requeued with a shadow exception instead of being put on hold for going over memory. (Ticket #4774).
Fixed a bug in ClassAds that can cause a crash if an attribute's value includes an eval() function that references the attribute's name. (Ticket #4813).
Fixed a rare bug that could cause the condor_schedd to write to an old daemon log file after log rotation. (Ticket #4761).
Fixed a slow memory leak in the Access Control List of the Windows desktop when configuration variable USE_VISIBLE_DESKTOP was enabled. (Ticket #4815).
Fixed a problem with the python bindings in which an invocation of function list() on specific forms of an ExprTree object would cause an infinite loop. (Ticket #4737).
Fixed a rare bug in which an attempt to send session invalidations via UDP occurred when no UDP socket was available. (Ticket #4556).
A regular expression specifies files within a configuration directory to be ignored when reading the HTCondor configuration. This regular expression has been expanded to also ignore backup files left by CFEngine and dpkg. (Ticket #4760).

Version 8.2.6

Release Notes:

HTCondor version 8.2.6 released on December 16, 2014.
Memory usage of the ec2_gahp may grow without bound due to a bug in some versions of libcurl. This occurs when jobs use x509:// URLs. Testing shows that libcurl version 7.38.0 does not have this issue. The fix may have been introduced as early as version 7.24.0. Therefore, if this problem occurs, consider upgrading the installation of libcurl. For operating systems whose vendor does not provide a new enough version of libcurl, build a more recent version, and use the configuration of EC2_GAHP to specify a wrapper script that sets up and invokes an ec2_gahp which uses the updated libcurl.

New Features:

None.

Bugs Fixed:

Corrected command line arguments to /bin/mail, adding the option to use sendmail. (Ticket #4764).
Fixed a bug introduced in HTCondor version 8.2.4 that caused the condor_schedd daemon log file to not rotate when configuration variable USE_CLONE_TO_CREATE_PROCESSES was set to True. (Ticket #4753).
Fixed a race condition that could cause the transfer of output files for HTCondor-C jobs to fail. HTCondor-C jobs are grid universe jobs with a grid type of condor. (Ticket #3379).
Fixed a bug in the Windows version of condor_submit that prevented a job from being submitted, if a directory specified with the submit command transfer_input_files contained a trailing forward slash character (/). condor_submit failed with an error message indicating that the directory could not be accessed, even when there was no problem accessing the directory. (Ticket #4747).
Fixed a problem that prevented HTCondor from starting on RHEL 7 platforms. The ownership of the directory /var/lock/condor/ was incorrect. (Ticket #4775).
Fixed a bug in which condor_qsub mishandled setting a disk space request with a command line argument of the form -l file=2048MB. (Ticket #4606).

Version 8.2.5

Release Notes:

HTCondor version 8.2.5 released on December 1, 2014.

New Features:

None.

Bugs Fixed:

Updated the post install script in the RPM packages, to preserve file /etc/condor/condor_config.local, if this file was modified since the last installation. (Ticket #4731).
Updated Windows builds of HTCondor to use the latest version of OpenSSL. (Ticket #4733).
Fixed a bug that caused file transfer to or from a condor_schedd daemon version 8.0 or older to fail when using the Python bindings, or when using the -address option with condor_submit or condor_transfer_data. (Ticket #4720).
Fixed a bug in condor_urlfetch that caused it to sometimes not fetch the URL when it should have, because the cache file did not exist. (Ticket #4732).
Fixed a bug that prevented grid-type batch jobs from being removed if they had an X.509 proxy that had been deleted. (Ticket #3072).
Fixed an inconsistency in which configuration variable JOB_RENICE_INCREMENT, if not explicitly set, defaulted to the value 10 for vanilla universe jobs and to the value 0 for standard universe jobs. It now defaults to 0, which matches the documentation. (Ticket #4697).
Fixed a bug in which condor_submit in interactive mode did not properly handle the -name command line option. (Ticket #4728).
Fixed a bug in error checking while performing job output file transfer for jobs in which job ClassAd attribute OutputDestination is used. (Ticket #4739).
Fixed a bug that caused nordugrid grid jobs to be held with the hold reason "Unspecified gridmanager error" when runtime information was not reported by the remote server. (Ticket #4736).

Version 8.2.4

Release Notes:

HTCondor version 8.2.4 released on Nov. 12, 2014.

New Features:

None.

Bugs Fixed:

Fixed a bug in which a condor_schedd daemon of an 8.2 version could not send jobs to, or obtain a claim on a condor_startd daemon of an 8.0 or previous version. (Ticket #4687).
Fixed a bug that could cause removed jobs to return to idle status. If a running job was removed at the same time that an error occurred that caused the condor_shadow to put the job on hold, the job would be put in the held status, but change to idle status when released. (Ticket #4619).
Changed the default value of configuration variable CONDOR_Q_USE_V3_PROTOCOL from True to False, and raised the default value of configuration variable SCHEDD_QUERY_WORKERS from 3 to 8. This works around condor_schedd performance issues caused by using this protocol when querying schedulers that handle large numbers of jobs. (Ticket #4696).
Fixed a bug that resulted in the condor_kbdd on Windows platforms sometimes exiting with error 0xC0000374, which indicates heap corruption. (Ticket #4634).
Fixed a bug that caused the condor_startd to report available disk attributes in bytes rather than kibibytes on Windows platforms. (Ticket #4638).
Changed the condor_master to work around a bug in the C Runtime on Windows platforms that resulted in the condor_master restarting whenever the system clock was changed to account for daylight savings time. (Ticket #3572).
Fixed a rare bug that could cause a daemon to core dump with a log message of "child failed because PID XXX is still in use by DaemonCore". (Ticket #4646).
Fixed a bug in the condor_shadow daemon that caused the user's supplemental groups to be unset when the condor_shadow process is reused to run another job. This could result in the job being held with a hold reason of "Failed to initialize user log to <path>". (Ticket #4672).
The RPM and Debian distributions no longer include a configuration file called condor_config.local, as this file is reserved for the use of local administration. And, condor_install or condor_configure no longer create file condor_config.local; they instead append to condor_config. (Ticket #4552).
Using condor_compile on programs which call posix_memalign() no longer causes a link error. (Ticket #4486).
Fixed a bug in which condor_router_q queried the wrong queue if the job router was configured to route jobs away from the source. (Ticket #4599).
Fixed a bug that prevented condor_chirp from finding its configuration file in the default location. (Ticket #4625).
Fixed a bug that could cause a daemon to write to an old daemon log file after log rotation. (Ticket #3106).
The HTCondor DRMAA library now works correctly when SCHEDD_HOST is set in the configuration file. (Ticket #4629).
Fixed the default value of the previously undocumented configuration variable HISTORY_HELPER_MAX_CONCURRENCY. It incorrectly defaulted to 10000, rather than the correct value of 2. (Ticket #4644).
Fixed a bug in the condor_schedd daemon that caused remote condor_history commands to fail if the configuration variable LIBEXEC was not explicitly set in a configuration file. (Ticket #4678).
For grid type condor grid universe jobs, if commands to the remote condor_schedd fail but the daemon appears to be running, then affected jobs will be placed in the Hold state. Previously, any failure to talk to the remote daemon would result in the condor_gridmanager considering the remote condor_schedd temporarily unavailable, and the condor_gridmanager waited for the remote condor_schedd to become available again. (Ticket #4557).
Fixed a bug in the condor_ganglia daemon that caused it to incorrectly log that gmetric was being used when condor_reconfig was invoked. (Ticket #4680).
Corrected the default value of configuration variable GANGLIAD_METRICS_CONFIG_DIR to be /etc/condor/ganglia.d in the RPM and Debian distributions. With the bug, the condor_gangliad daemon would fail to start when it could not locate this incorrectly specified directory. (Ticket #4709).

Version 8.2.3

Release Notes:

HTCondor version 8.2.3 released on October 1, 2014.
This version of HTCondor includes a full port for Ubuntu 14.04 on the x86_64 architecture. A full port includes support for the standard universe. (Ticket #4562).

New Features:

The new configuration variable RUN_FILETRANSFER_PLUGINS_WITH_ROOT permits file transfer plug-ins to run with root privilege, when HTCondor daemons are run as root, and when set to the non-default value of True. (Ticket #4561).
The new configuration variable NETWORK_HOSTNAME sets the host name that HTCondor uses to identify the local machine. If NETWORK_HOSTNAME is not set, then HTCondor uses the gethostname() function to determine the machine's host name. This variable is useful if a machine has multiple network interfaces with different host names. (Ticket #4570).
Configuration variable JOB_ROUTER_DEFAULTS tolerates the syntax of omitting the outer square brackets that would be required by new ClassAd syntax, in order to facilitate appending to an existing value. If the value of JOB_ROUTER_DEFAULTS does not have enclosing square brackets, the value will be parsed as if they are present. (Ticket #4433).

Bugs Fixed:

The RedHat 7 RPM contains the service file to start up HTCondor via systemd instead of via init scripts. (Ticket #4534).
EC2 grid universe jobs which use the X.509 authentication method will no longer crash if environment variable USER is not set. (Ticket #4540).
Fixed a rare memory leak. The leak occurred when IPv6 was disabled, but configuration variables NETWORK_INTERFACE and COLLECTOR_HOST were set to IPv6 addresses. (Ticket #4502).
Fixed a bug in which condor_qsub mishandled setting a memory request with a command line argument similar to -l mem=2048MB. (Ticket #4549).
Fixed a bug that caused the condor_gridmanager to fail to talk to the condor_schedd if the user's account was in a Windows domain. (Ticket #4568).
On Windows platforms, users listed in the QUEUE_SUPER_USERS configuration variable are now checked in a case-insensitive way, since user names are case-insensitive on Windows. (Ticket #4579).
Fixed a bug that could prevent the condor_schedd job queue log from rotating on Windows platforms. (Ticket #4548).
Fixed a bug that caused all HTCondor daemons to leak a small amount of memory upon reconfiguration. (Ticket #4582).
Fixed a bug that caused condor_config_val -verbose to sometimes append incorrect meta-knob information to the file and line number information for a configuration variable. (Ticket #4559).
Fixed a bug that sometimes prevented adding a .txt file name extension to the log file name of an HTCondor daemon on Windows platforms. (Ticket #4571).
Fixed a bug that caused condor_dagman to crash if configuration variable DAGMAN_ALWAYS_USE_NODE_LOG was set to False and configuration variable DAGMAN_USE_STRICT was set to 1 or a higher value. (Ticket #4600).
Fixed a bug that caused the DAG node status file (if one is specified) to have the wrong final status for a DAG that is aborted by an ABORT-DAG-ON specification. (Ticket #4312).
Fixed a bug in the batch_gahp that could cause it to fail when attempting to query the status of an LSF job. (Ticket #4592).

Known Bugs:

On Windows platforms only, issuing condor_rm on a condor_dagman job does not work correctly. The condor_dagman process is immediately killed, and it does not write a Rescue DAG or remove its node jobs. Note that this bug has probably existed since DAGMan was first implemented on the Windows platform. (Ticket #4566).

Version 8.2.2

Release Notes:

HTCondor version 8.2.2 released on August 7, 2014.
This version of HTCondor includes a full port for Red Hat Enterprise Linux 7.0 on the x86_64 architecture. A full port includes support for the standard universe. (Ticket #4511).
The RPM for RHEL 7 contains several subpackages for elements of HTCondor, modernizing the RPM-based installation. (Ticket #4518).

New Features:

None.

Bugs Fixed:

When using the Windows installer, the choice of a new pool caused an invalid value in the configuration of $$(FULL_HOSTNAME) to be used, instead of the correct value of $(FULL_HOSTNAME). This prevented all daemons from talking to the condor_collector daemon. (Ticket #4509).
Fixed a bug that only manifested on Linux 3.14 or more recent kernels, which caused the condor_collector to respond very slowly to queries. (Ticket #4489).
Fixed a Windows platform bug that caused condor_status to abort when ENABLE_CLASSAD_CACHING was set to True. (Ticket #4459).
Fixed a bug that prevented the detection of hyper-threaded cores on Linux platforms. All cores reported as full cores without hyper-threading. (Ticket #4458).
Fixed the detection of hyper-threaded cores on Mac OS X platforms. (Ticket #4516).
Fixed a Windows platform bug that caused the condor_starter to abort while creating the job sandbox. The bug presents as a minor memory leak in all versions of HTCondor for Windows prior to version 8.2.2 and 8.3.0. In HTCondor version 8.2.0, this bug could sometimes present as an abrupt condor_starter exit with status -1073740940. (Ticket #4467).
Fixed a file descriptor leak in the condor_shared_port daemon. (Ticket #4456).
Fixed a bug existing on Linux platforms with newer kernels. With cgroups enabled, the OOM killer killed the job when the job went over its memory allocation. Now, the condor_starter catches the OOM signal and places the job on hold with an appropriate message. (Ticket #4435).
Fixed a bug in which the expression set by submit command periodic_remove would not remove jobs running on Linux machines when PID namespaces were enabled. (Ticket #4421).
Fixed a Windows-specific bug: specifying a DAG node status file caused DAGMan to fail. (Ticket #4361).
Fixed a problem in which job rank may not have always worked as documented due to a bug in HTCondor's auto cluster mechanism. (Ticket #4403).
Updated the HTCondor DRMAA library to version 1.6.2. This version fixes minor bugs in the functions for querying how a job exited. (Ticket #4413).
condor_submit no longer fails if the value of x509userproxy is a relative path, and the value of initialdir is set to a directory that is not the current working directory of condor_submit. (Ticket #4415).
Fixed a bug that caused condor_submit_dag to core dump if a non-existent DAG file was specified. (Ticket #4423).
Fixed a bug that resulted in output of the string "undefined", instead of printing nothing, when using the %s format specifier to condor_q -format. (Ticket #4418).
Fixed a bug in the condor_shadow that caused the user's supplemental groups to be unset when trying to write to the user's job event log. This could result in the job being held with the hold reason "Failed to initialize user log to <path>". (Ticket #4437).
Fixed a bug in the cream_gahp that would corrupt memory when using more than the default number of worker threads. (Ticket #4416).
Fixed a bug that could cause the cream_gahp to fail at start up, because it could not locate a Globus threading library. (Ticket #4440).
When a daemon checks whether a user has execute permission for a directory, it now considers supplemental groups and POSIX ACLs in the determination. (Ticket #4402).
Fixed a bug that could cause GSI security operations to fail if GLOBUS_THREAD_MODEL was set in the environment. (Ticket #4464).
Fixed a bug in condor_ft-gahp that caused it to ignore the peer version given by the CONDOR_VERSION command, causing it to think that its file transfer peer was the same version as itself. (Ticket #4473).
Fixed the handling of optional authentication parameters given to remote_gahp. This is used as part of the batch grid-type when submitting jobs to a remote system via ssh. (Ticket #4434).
Fixed a bug in the parsing the value set for the Detected<Tag> attribute of the output of a script specified by configuration variable MACHINE_RESOURCE_INVENTORY_<TAG>. If the value of Detected<Tag> was not a string, then it would not be parsed correctly. As a result the resource quantity would be set to 0. (Ticket #4427).

Version 8.2.1

HTCondor version 8.2.1 released on July 7, 2014.
Security Item: This release of HTCondor fixes a security-related bug described at http://research.cs.wisc.edu/htcondor/security/vulnerabilities/HTCONDOR-2014-0001.html. (Ticket #4420).

New Features:

None.

Bugs Fixed:

None.

Version 8.2.0

Release Notes:

HTCondor version 8.2.0 released on June 24, 2014.

New Features:

The new configuration variable SOCKET_LISTEN_BACKLOG controls the listen backlog setting for a daemon's command port. The default value of 500 implements the previously hard coded value. (Ticket #4393).
Streamlined the network protocol used by condor_submit, resulting in faster job submission times and less condor_schedd overhead, especially when performing a submit to a remote condor_schedd. (Ticket #3846).
The default value for configuration variable CLAIM_WORKLIFE has changed from 60 minutes to 20 minutes. (Ticket #4374).
The default value for configuration variable NEGOTIATOR_PRE_JOB_RANK has changed to prefer to match multi-core jobs to dynamic slots in a best-fit manner. And, the default value for configuration variable PREEMPTION_RANK has changed to first choose the user with the worst priority, and then choose the job of that user with the least amount of accumulated run time. (Ticket #4374).
The default set of metrics published by the condor_gangliad has been reduced to an essential set of scheduler and negotiator metrics. Also, the units for accumulated times have changed from seconds to hours. (Ticket #4299).

Bugs Fixed:

Fixed a bug that caused a memory leak in the condor_procd when cgroup tracking is enabled. (Ticket #4408).
Fixed a bug that caused a memory leak in the condor_collector under heavy load. This bug was introduced in HTCondor version 8.1.5. (Ticket #4370).
Windows machines with more than nine dynamic slots may have failed to start jobs due to a limit on the number of characters in a user name. To address this limit, the user name is shortened from condor-reuse-slot<N> to condor-slot<N>. (Ticket #4388).
Fixed a bug in which condor_q failed to communicate with a condor_schedd of HTCondor version 8.1.4. (Ticket #4384).
Fixed bugs introduced in HTCondor version 8.1.5 that caused communication between the cream_gahp and the remote CREAM servers to fail. (Ticket #4392).
Fixed a bug introduced in HTCondor version 8.1.2 that caused grid-type cream jobs to fail when copy_to_spool was set to True in the submit description file. (Ticket #4391).
When submitting a grid universe job with a grid type of batch and setting request_memory, the job would fail if the remote batch system was HTCondor. This has been fixed. (Ticket #4367).
Improved the detection of IPv4 link-local addresses. (Ticket #4341).
