Version 10 Feature Releases

We release new features in these releases of HTCondor. The details of each version are described below.

Version 10.9.0

Release Notes:

  • HTCondor version 10.9.0 released on September 28, 2023.

  • This version includes all the updates from Version 10.0.9.

New Features:

  • None.

Bugs Fixed:

  • None.

Version 10.8.0

Release Notes:

  • HTCondor version 10.8.0 released on September 14, 2023.

  • The packaged builds (RPMs and debs) have been reorganized. We no longer wish to support the ClassAd library and it has been folded into the main condor package. The condor-blahp and condor-procd packages have also been folded into the condor package. (HTCONDOR-1981)

  • On Debian based systems, the HTCondor’s libexec directory has moved to the more standard /usr/libexec/condor. (HTCONDOR-1981)

  • The Debian packaging has been aligned with the RPM packaging. The package names are now condor and minicondor. The condor-kbdd package has been split out, since many installations are server based and do not require the keyboard daemon and all of its dependencies on the X Window system. Also, the condor-vm-gahp package has been split out for sites that do not want to support VM Universe and the libvirt dependencies that come along with it. (HTCONDOR-1987)

  • This version includes all the updates from Version 10.0.8.

New Features:

  • In an HTCondor Execution Point started by root on Linux, the default for cgroups memory has changed to be enforcing. This means that jobs that use more then their provisioned memory will be put on hold with an appropriate hold message. condor_q -hold will show that message. The previous default can be restored by setting CGROUP_MEMORY_LIMIT_POLICY = none on the Execution points. (HTCONDOR-1974)

  • Added a -gpus option to condor_status. With this option condor_status will show only machines that have GPUs provisioned; and it will show information about the GPU properties. (HTCONDOR-1958)

  • The output of condor_status when using the -compact option has been improved to show a separate row for the second and subsequent slot type for machines that have multiple slot types. Also the totals now count slots that have the BackfillSlot attribute under the Backfill or BkIdle columns. (HTCONDOR-1957)

  • Added new DAG command ENV for DAGMan. This command allows users to specify environment variables to be added into the DAGMan job proper’s environment either by setting values explicitly or getting them from the environment the job is submitted from. (HTCONDOR-1955)

  • Improved output for htcondor dag status command to include more information about the specified DAG. (HTCONDOR-1951)

  • Updated DAGMan to utilize the -reason flag to add a message about why a job was removed when DAGMan removes managed jobs via condor_rm for some reason. (HTCONDOR-1950)

  • Partitionable slots can now be directly claimed by a condor_schedd (i.e. the State of the partitionable slot changes to Claimed). While a slot is claimed, no other condor_schedd is able to create new dynamic slots to run jobs. This is controlled by the new configuration parameter ENABLE_CLAIMABLE_PARTITIONABLE_SLOTS and is disabled by default. (HTCONDOR-1824)

  • By default, the user event logs are no longer fsync’d by the condor_schedd. This should improve the performance of the condor_schedd, especially when the user’s event logs are on non-solid state disks. There is a knob to revert to the old semantics, ENABLE_USERLOG_FSYNC, which defaults to false. (HTCONDOR-1550)

  • A new configuration variable ALLOW_SUBMIT_FROM_KNOWN_USERS_ONLY was added to allow administrators to restrict job submission to users that have already been added to the condor_schedd using the condor_qusers tool. (HTCONDOR-1934)

  • Updated condor_upgrade_check script to check and warn about known incompatibilities introduced in the feature series for HTCondor V10 that can cause issues when upgrading to a newer version (i.e. HTCondor V23). (HTCONDOR-1960)

  • Self-checkpointing jobs may now include the time spent generating successfully-stored checkpoints as part of their CommittedTime job ad attribute. (HTCONDOR-1942)

Bugs Fixed:

  • Fixed a bug introduced in 10.5.0 that caused jobs to fail to start if they requested an OAuth credential whose service name included an asterisk. (HTCONDOR-1966)

  • Fixed bugs in condor_store_cred that could cause it to crash or write incorrect data for the pool password. (HTCONDOR-1587)

  • Fixed a bug with condor_ssh_to_job where it would fail if the Execution point was behind CCB, and the command was run immediately after the job started. (HTCONDOR-1979)

  • Some support scripts for the htcondor annex command are now properly installed as executable. (HTCONDOR-1984)

  • Fixed a bug where condor_remote_cluster could get stuck in a loop while installing files into an NFS directory. (HTCONDOR-2023)

Version 10.7.1

  • HTCondor version 10.7.1 released on August 9, 2023.

New Features:

  • None.

Bugs Fixed:

  • Fixed inefficiency in DAGMan setting a nodes descendants to futile status which would result in DAGMan taking an extremely long time when a node fails in a very large and bushy DAG. (HTCONDOR-1945)

Version 10.7.0

Release Notes:

  • HTCondor version 10.7.0 released on July 31, 2023.

  • This version includes all the updates from Version 10.0.7.

  • Add support for Debian 12 (bookworm). (HTCONDOR-1938)

New Features:

  • A single HTCondor pool can now have multiple condor_defrag daemons running and they will not interfere with each other so long as each has DEFRAG_REQUIREMENTS that select mutually exclusive subsets of the pool. (HTCONDOR-1903)

  • If a job does not define any of the periodic policy expressions (like periodic_hold), HTCondor no longer sets a default value (like false) in the job ad. The system knows that if these aren’t set, to take the default action. This removes about 10% of the attributes in a job ad, with corresponding benefits for all consumers of the job ad. (HTCONDOR-1919)

  • Added submit command want_io_proxy. This replaces the old command +WantIOProxy. (HTCONDOR-1875)

  • Apptainer is now included in the tarballs. (HTCONDOR-1932)

Bugs Fixed:

  • Fixed bug introduced in 10.5.0 on cgroup v1 systems where the user and system CPU time measured was low by a factor of 10,000. (HTCONDOR-1920)

  • Fixed a bug introduced in V10.5.0 of HTCondor where the and failed to be written to a local universe jobs scratch directory because of the condor_starter having the wrong permissions. (HTCONDOR-1912)

  • If the collector is storing offline ads via COLLECTOR_PERSISTENT_AD_LOG the condor_preen tool will no longer delete that file (HTCONDOR-1874)

  • Fixed a bug where empty execute sandboxes failed to be cleaned up on the Execution Point when using Startd disk enforcement. (HTCONDOR-1821)

  • When using Startd disk enforcement, if a condor_starter running a container or VM universe job is abruptly killed (like SIGABRT) then the condor_startd would fail to cleanup the running docker container or VM and underlying logical volume. (HTCONDOR-1895)

Version 10.6.0

Release Notes:

  • HTCondor version 10.6.0 released on June 29, 2023.

  • This version includes all the updates from Version 10.0.6.

New Features:

  • Added the condor_qusers command to monitor and control users at the Access Point. Users disabled at the Access Point are no longer allowed to submit jobs. Jobs submitted before the user was disabled are allowed to run to completion. When a user is disabled, an optional reason string can be provided. The reason will be included in the error message from condor_submit when submission is refused because the user is disabled. (HTCONDOR-1723) (HTCONDOR-1835)

  • Mitigate a memory leak in the arc_gahp with libcurl when it uses NSS for security. When an arc_gahp process has handled a certain number of commands, a new arc_gahp is started and old process exits. The number of commands that triggers a new process is controlled by new configuration parameter ARC_GAHP_COMMAND_LIMIT. (HTCONDOR-1778)

  • Container universe jobs may now specify the container_image to be an image transferred via a file transfer plugin. (HTCONDOR-1820)

  • Added two new functions for using ClassAd expressions. The stringListSubsetMatch and stringListISubsetMatch functions can be used to check if all of the members of a stringlist are also in a target stringlist. A single stringListSubsetMatch function call can replace a whole set of stringListMember calls once the whole pool is updated to 10.6.0. (HTCONDOR-1817)

  • Added a new automatic submit file macro $(JobId) which expands to the full id of the submitted job. (HTCONDOR-1836)

  • The job’s executable is no longer renamed to condor_exec.exe when the job’s sandbox is transferred to the Execution Point. (HTCONDOR-1227)

Bugs Fixed:

  • condor_restd service in the htcondor/mini container no longer crashes on startup due to the en_US.UTF-8 locale being unavailable. (HTCONDOR-1785)

  • Fixed a bug that would very rarely cause condor_wait to hang forever. (HTCONDOR-1792)

Version 10.5.1

  • HTCondor version 10.5.1 released on June 6, 2023.

New Features:

  • None.

Bugs Fixed:

  • For grid universe jobs of type batch, detecting if a Slurm system is functioning now works with older versions of Slurm. (HTCONDOR-1826)

Version 10.5.0

Release Notes:

  • HTCondor version 10.5.0 released on June 5, 2023.

  • This version includes all the updates from Version 10.0.4.

  • Add support for Amazon Linux 2023. VOMS authentication is omitted on this platform. (HTCONDOR-1742)

New Features:

  • Added new Save File functionality to DAGMan which allows users to specify DAG nodes as save points to record the current DAG’s progress in a file similar to a rescue file. These files can then be specified with the new condor_submit_dag flag load_save to re-run the DAG from that point of progression. For more information visit DAG Save Point Files. (HTCONDOR-1636)

  • The admin knob SUBMIT_ALLOW_GETENV when set to false, now allows submit files to use any value but true for their getenv = ... commands. (HTCONDOR-1671)

  • Improved throughput when submitting a large number of ARC CE jobs. Previously, jobs could remain stalled for a long time in the ARC CE server waiting for their input sandbox to be transferred while other were being submitted. (HTCONDOR-1666)

  • The arc_gahp can now issue multiple HTTPS requests in parallel in different threads. This is controlled by the new configuration parameter ARC_GAHP_USE_THREADS. (HTCONDOR-1690)

  • The Execute event in the user log now prints out slot name, sandbox path and resource quantities of execution slot. (HTCONDOR-1722)

  • Added new submit command ulog_execute_attrs for a jobs submit file. This command takes a comma-separated list of machine ClassAd attributes to be written to the user logs execute event. (HTCONDOR-1759)

  • Added new DAGMan configuration macro DAGMAN_RECORD_MACHINE_ATTRS to give a list of machine attributes that will be added to DAGMan submitted jobs for recording in the various produced job ads and userlogs. (HTCONDOR-1717)

  • The condor_transform_ads tool can now read a configuration file containing JOB_TRANSFORM_<name> or JOB_ROUTER_ROUTE_<name> and then apply any or all of the transforms declared in that file. This makes it easier to test job transforms before deploying them. (HTCONDOR-1710)

  • Linux Cgroup support has been redone in a way that doesn’t depend on using the procd. There should be no user visible changes in the usual cases. (HTCONDOR-1589)

Bugs Fixed:

  • Expanded default list of environment variables to include in the DAGMan proper manager jobs getenv to include HOME, USER, LANG, and LC_ALL. Thus resulting in these variables appearing in the DAGMan manager jobs environment. (HTCONDOR-1725)

  • Fixed a bug on cgroup v2 systems where memory limits over 2 gigabytes would not be enforced correctly. (HTCONDOR-1775)

  • HTCondor no longer puts jobs using cgroup v1 into the blkio controller. HTCondor never put limits on the i/o, and some kernel version panicked and crashed when they had active jobs in the blkio controller. (HTCONDOR-1786)

  • Forced condor_ssh_to_job to never try to use a Control Master, which would break ssh_to_job. Also raised the timeout for ssh_to_job which might be needed for slow WANs. (HTCONDOR-1782)

  • Fixed a bug when running with root on a Linux systems with cgroup v1 that would print a warning to the StarterLog claiming Warning: cannot chown /sys/fs/cgroup/cpu,cpuset (HTCONDOR-1672)

  • Fixed a bug where condor_history would fail to find history files for a remote query if the various history configuration macros were specified with subsystem prefixes i.e. SCHEDD.HISTORY = /path (HTCONDOR-1739)

  • When started on a systemd system, HTCondor will now wait for the SSSD service to start. Previously it only waited for ypbind. (HTCONDOR-1655)

  • Fixed a bug in condor_preen that would remove any recorded job epoch history files stored in the spool directory. (HTCONDOR-1738)

Version 10.4.3

Release Notes:

  • HTCondor version 10.4.3 released on May 9, 2023.

  • Tarballs in this release contain the recent scitokens-cpp 1.0.1 library. (HTCONDOR-1779)

New Features:

  • None.

Bugs Fixed:

Version 10.4.2

  • HTCondor version 10.4.2 released on May 2, 2023.

New Features:

  • None.

Bugs Fixed:

  • Fixed a bug introduced in HTCondor 10.0.3 that caused remote submission of batch grid universe jobs via ssh to fail when attempting to do file transfer. (HTCONDOR-1747)

  • Fixed a bug where the HTCondor-CE would fail to handle any of its jobs after a restart. (HTCONDOR-1755)

Version 10.4.1

Release Notes:

  • HTCondor version 10.4.1 released on April 12, 2023.

  • Preliminary support for Ubuntu 20.04 (Focal Fossa) on PowerPC (ppc64el). (HTCONDOR-1668)

New Features:

  • None.

Bugs Fixed:

  • condor_remote_cluster now works correctly when the hardware architecture of the remote machine isn’t x86_64. (HTCONDOR-1670)

Version 10.4.0

Release Notes:

  • HTCondor version 10.4.0 released on April 6, 2023.

  • This version includes all the updates from Version 10.0.3.

  • HTCondor will no longer pass all environment variables to the DAGMan proper manager jobs environment. This may result in DAGMan and its various parts (primarily PRE, POST,& HOLD Scripts) to start failing or change behavior due to missing needed environment variables. To revert back to the old behavior or add the missing environment variables to the DAGMan proper jobs environment set the DAGMAN_MANAGER_JOB_APPEND_GETENV configuration option. (HTCONDOR-1580)

  • The condor_startd will no longer advertise CpuBusy or CpuBusyTime unless the configuration template use POLICY : DESKTOP or use POLICY : UWCS_DESKTOP is used. Those templates will cause CpuBusyTime to be advertised as a time value and not a duration value. The policy expressions in those templates have been modified to account for this fact. If you have written policy expressions of your own that reference CpuBusyTime you will need to modify them to use $(CpuBusyTimer) from one of those templates or make the equivalent change. (HTCONDOR-1502)

New Features:

  • DAGMan no longer sets getenv = true in the .condor.sub file while adding the ability to better control the environment passed to the DAGMan proper job. getenv will default to CONDOR_CONFIG,_CONDOR_*,PATH,PYTHONPATH,PERL*,PEGASUS_*,TZ in the .condor.sub file which can be appended to via the DAGMAN_MANAGER_JOB_APPEND_GETENV or the new condor_submit_dag flag include_env. Also added new condor_submit_dag flag insert_env to directly set key=value pairs of information into the .condor.sub environment. (HTCONDOR-1580)

  • New configuration parameter SEC_SCITOKENS_FOREIGN_TOKEN_ISSUERS restricts which issuers’ tokens will be accepted under SEC_SCITOKENS_ALLOW_FOREIGN_TOKEN_TYPES. Updated default values allow EGI CheckIn tokens to be accepted under the SCITOKENS authentication method. (HTCONDOR-1515)

  • The condor_startd can now be configured to evaluate a set of expressions defined by STARTD_LATCH_EXPRS. For each expression, the last evaluated value will be advertised as well as the time that the evaluation changed to that value. This new generic mechanism was used to add a new slot attribute NumDynamicSlotsTime that is the last time a dynamic slot was created or destroyed. (HTCONDOR-1502)

  • Add new field ContainerDuration to TransferInput attribute of jobs that measure the number of seconds to transfer the Apptainer/Singularity image. (HTCONDOR-1588)

  • For grid universe jobs of type batch, add detection of when the target batch system is unreachable or not functioning. When this is the case, HTCondor marks the resource as unavailable instead of putting the affected jobs on hold. This matches the behavior for other grid universe job types. Grid ads in the collector now contain attributes GridResourceUnavailableTimeReason and GridResourceUnavailableTimeReasonCode, which give details about why the remote scheduling system is considered unavailable. (HTCONDOR-1582)

  • Added ability for DAGMan to automatically record the Node Retry attempt in that nodes job ad. This is done by setting the new configuration option DAGMAN_NODE_RECORD_INFO. (HTCONDOR-1634)

Bugs Fixed:

  • Fixed a bug where if the docker command emitted warnings to stderr, the condor_startd would not correctly advertise the amount of used image cache. (HTCONDOR-1645)

  • Fixed a bug where condor_history would fail if the job history file doesn’t exist. (HTCONDOR-1578)

  • Fixed a bug in the view server where it would assert and exit if the view server stats file are deleted at just the wrong time. (HTCONDOR-1599)

  • Fixed a bug where condor_shadow was unable to write the job ad to the JOB_EPOCH_HISTORY file when located in condor owned directories such as the spool directory. (HTCONDOR-1631)

  • Remove warning when installing HTCondor RPMs on Enterprise Linux 9. (HTCONDOR-1571)

Version 10.3.1

  • HTCondor version 10.3.1 released on March 7, 2023.

New Features:

  • The condor_startd now advertises whether there appears to be a useful /usr/sbin/sshd on the system, in order for condor_ssh_to_job to work. (HTCONDOR-1614)

Bugs Fixed:

  • None.

Version 10.3.0

Release Notes:

  • HTCondor version 10.3.0 released on March 6, 2023.

  • This version includes all the updates from Version 10.0.2.

  • When HTCondor is configured to use cgroups, if the system as a whole is out of memory, and the kernel kills a job with the out of memory killer, HTCondor now checks to see if the job is below the provisioned memory. If so, HTCondor now evicts the job, and marks it as idle, not held, so that it might start again on a machine with sufficient resources. Previous, HTCondor would let this job attempt to run, hoping the next time the OOM killer fired it would pick a different process. (HTCONDOR-1512)

  • This version changes the semantics of the output_destination submit command. It no longer sends the files named by the output or error submit commands to the output destination. Submitters may instead specify those locations with URLs directly. (HTCONDOR-1365)

New Features:

  • When HTCondor has root, and is running with cgroups, the cgroup the job is in is writeable by the job. This allows the job (perhaps a glidein) to sub-divide the resource limits it has been given, and allocate subsets of those to its child processes. (HTCONDOR-1496)

  • Added capabilities for per job run instance history recording. Where during the condor_shadow daemon’s shutdown it will write the current job ad to a file designated by JOB_EPOCH_HISTORY and/or a directory specified by JOB_EPOCH_HISTORY_DIR. These per run instance job ad records can be read via condor_history using the new -epochs option. This behavior is not turned on by default. Setting either of the job epoch location config knobs above will turn on this behavior. (HTCONDOR-1104)

  • Added new condor_history -search option that takes a filename to find all matching condor time rotated files filename.YYYYMMDDTHHMMSS to read from instead of using any default files. (HTCONDOR-1514)

  • Added new condor_history -directory option to use a history sources alternative configured directory knob such as JOB_EPOCH_HISTORY_DIR to search for history. (HTCONDOR-1514)

  • Added ability to set a gangliad metrics lifetime (DMAX value) within the metric definition language with the new Lifetime keyword. (HTCONDOR-1547)

  • Added configuration knob GANGLIAD_MIN_METRIC_LIFETIME to set the minimum value for gangliads calculated metric lifetime (DMAX value) for all metrics without a specified Lifetime. (HTCONDOR-1547)

  • Added an attribute to the condor_schedd classad that advertises the number of late materialization jobs that have been submitted, but have not yet materialized. The new attribute is called JobsUnmaterialized (HTCONDOR-1591)

  • The linux_kernel_tuning_script, run by the condor_master at startup, now tries to increase the value of /proc/sys/fs/pipe-user-pages-soft to 128k, if it was below this. This improves the scalability of the condor_schedd when running more than 16k jobs from any one user. (HTCONDOR-1556)

  • The linux_kernel_tuning_script, run by the condor_master at startup, no longer tries to mount the various cgroup filesystems. We assume that any reasonable Linux system will have done this in a manner that it deems appropriate. (HTCONDOR-1528)

  • Linux worker nodes now advertise DockerCachedImageSizeMb, the number of megabytes that are used in the docker image cache. (HTCONDOR-1494)

  • When a file-transfer plug-in aborts due to lack of progress, the message now includes the https_proxy (or http_proxy) environment variable, and the phrasing has been changed to avoid suggesting that the plug-in actually respected it. (HTCONDOR-1473)

Bugs Fixed:

  • Added support for older cgroup v2 systems with missing memory.peak files in the memory controller. (HTCONDOR-1529)

  • The HTCondor starter now removes any cgroup that it has created for a job when it exits. (HTCONDOR-1500)

  • Fixed bug where condor_history would occasionally fail to display all matching user requested job ids. (HTCONDOR-1506)

  • Fixed bugs in how the condor_collector generated its own CA and host certificate files. Configuration parameter COLLECTOR_BOOTSTRAP_SSL_CERTIFICATE now defaults to True on Unix platforms. Configuration parameters AUTH_SSL_SERVER_CERTFILE and AUTH_SSL_SERVER_KEYFILE can now be a list of files. The first pair of files with valid credentials is used. (HTCONDOR-1455)

  • Added missing environment variables for the SciTokens plugin. (HTCONDOR-1516)

Version 10.2.5

  • HTCondor version 10.2.5 released on February 28, 2023.

New Features:

  • None.

-Bugs Fixed:

  • Fixed an issue where after a condor_schedd restart, the JobsUnmaterialized attribute in the condor_schedd ad may be an overcount of the number of unmaterialized jobs in rare cases. (HTCONDOR-1606)

Version 10.2.4

Release Notes:

  • HTCondor version 10.2.4 released on February 24, 2023.

New Features:

  • None.

Bugs Fixed:

  • Fixed an issue where after a condor_schedd restart, the JobsUnmaterialized attribute in the condor_schedd ad may be an undercount of the number of unmaterialized jobs for previous submissions. (HTCONDOR-1591)

Version 10.2.3

  • HTCondor version 10.2.3 released on February 21, 2023.

New Features:

  • Added an attribute to the condor_schedd ClassAd that advertises the number of late materialization jobs that have been submitted, but have not yet materialized. The new attribute is called JobsUnmaterialized. (HTCONDOR-1591)

Bugs Fixed:

  • None.

Version 10.2.2

Release Notes:

  • HTCondor version 10.2.2 released on February 7, 2023.

New Features:

  • None.

Bugs Fixed:

  • Fixed bugs with configuration knob SINGULARITY_USE_PID_NAMESPACES. (HTCONDOR-1574)

Version 10.2.1

  • HTCondor version 10.2.1 released on January 24, 2023.

New Features:

  • Improved scalability of condor_schedd when running more than 1,000 jobs from the same user. (HTCONDOR-1549)

  • condor_ssh_to_job should now work in glidein and other environments where the job or HTCondor is running as a Unix user id that doesn’t have an entry in the /etc/passwd database. (HTCONDOR-1543)

Bugs Fixed:

  • In the Python bindings, the attribute ServerTime is now included in job ads returned by Schedd.query(). (HTCONDOR-1531)

  • Fixed issue when HTCondor could not be installed on Ubuntu 18.04 (Bionic Beaver). (HTCONDOR-1548)

Version 10.2.0

Release Notes:

  • HTCondor version 10.2.0 released on January 5, 2023.

  • This version includes all the updates from Version 10.0.1.

  • We changed the semantics of relative paths in the output, error, and transfer_output_remaps submit file commands. These commands now create the directories named in relative paths if they do not exist. This could cause jobs that used to go on hold (because they couldn’t write their output or error files, or a remapped output file) to instead succeed. (HTCONDOR-1325)

  • HTCondor can now put a job in a Linux control (cgroup), not only if it has root privilege, but also if the administrator or some external entity has made the cgroup HTCondor is configured to use writeable by the non-rootly user a personal condor or glidein is running as. (HTCONDOR-1465)

  • File-transfer plug-ins may no longer take as long as they like to finish. After MAX_FILE_TRANSFER_PLUGIN_LIFETIME seconds, the starter will terminate the transfer and report a time-out failure (with ETIME, 62, as the hold reason subcode). (HTCONDOR-1404)

New Features:

  • Add support for Enterprise Linux 9 on x86_64 and aarch64 architectures. (HTCONDOR-1285)

  • Add support to the condor_starter for tracking processes via cgroup v2 on Linux distributions that support cgroup v2. (HTCONDOR-1457)

  • The condor_negotiator now support setting a minimum floor number of cores that any given submitter should get, regardless of their fair share. This can be set or queried via the condor_userprio tool, in the same way that the ceiling can be set or get (HTCONDOR-557)

  • Improved the validity testing of the Singularity / Apptainer container runtime software at condor_startd startup. If this testing fails, slot attribute HasSingularity will be set to false, and attribute SingularityOfflineReason will contain error information. Also in the event of Singularity errors, more information is recorded into the condor_starter log file. (HTCONDOR-1431)

  • condor_q default behavior of displaying the cumulative run time has changed to now display the current run time for jobs in running, transferring output, and suspended states while displaying the previous run time for jobs in idle or held state unless passed -cumulative-time to show the jobs cumulative run time for all runs. (HTCONDOR-1064)

  • Docker Universe submit files now support docker_pull_policy = always, so that docker will check to see if the cached image is out of date. This increases the network activity, may cause increased throttling when pulling from docker hub, and is recommended to be used with care. (HTCONDOR-1482)

  • Added configuration knob SINGULARITY_USE_PID_NAMESPACES. (HTCONDOR-1431)

  • condor_history will now stop searching history files once all requested job ads are found if passed ClusterIds or ClusterId.ProcId pairs. (HTCONDOR-1364)

  • Improved condor_history search speeds when searching for matching jobs, matching clusters, and matching owners. (HTCONDOR-1382)

  • The local issuer credmon can optionally add group authorizations to users’ tokens by setting LOCAL_CREDMON_AUTHZ_GROUP_TEMPLATE and LOCAL_CREDMON_AUTHZ_GROUP_MAPFILE. (HTCONDOR-1402)

  • The JOB_INHERITS_STARTER_ENVIRONMENT configuration variable now accepts a list of match patterns just like the submit command getenv does. (HTCONDOR-1339)

  • Declaring either container_image or docker_image without a defined universe in a submit file will now automatically setup job for respective universe based on image type. (HTCONDOR-1401)

  • Added new Scheduler ClassAd attribute EffectiveFlockList that represents the condor_collector addresses that a condor_schedd is actively sending flocked jobs. (HTCONDOR-1389)

  • Added new DAGMan node status called Futile that represents a node that will never run due to the failure of a node that the Futile node depends on either directly or indirectly through a chain of PARENT/CHILD relationships. Also, added a new ClassAd attribute DAG_NodesFutile to count the number of Futile nodes in a DAG. (HTCONDOR-1456)
