GlideinWMS The Glidein-based Workflow Management System

Compatibility Statement

GlideinWMS strives to have Factory and Frontends compatible across versions. If there is an incompatibility:

• Any incompatibility will be always clearly stated in the release notes
• We will not require to have to upgrade Factory and Frontends at the same time. If this is unavoidable, a major version change should happen
• If a change causing incompatibility is needed, we will prefer to require to upgrade the Factory before the Frontends and not the opposite (i.e. the newer Factory will be compatible with the older Frontends). If this happens, at least a minor version change should happen.

  • NOTE-FACTORY: When generating cvmfsexec distribution for EL9 machine type on an EL7 machine, the factory reconfig and/or upgrade fails as a result of an error in `create_cvmfsexec_distros.sh`. This is possibly due to the tools for EL7 being unable to handle EL9 files (as per Dave Dykstra). Please exercise caution if using `rhel9-x86_64` in the `mtypes` list for the `cvmfsexec_distro` tag in factory configuration. - Our workaround is to remove the EL9 machine type from the default list of machine types supported by the custom distros creation script. Add it back if you are running on an EL9 system and want an EL9 cvmfsexec distrinution. (PR#312)'

  • NOTE-FACTORY: The rebuilding of cvmfsexec distributions is now disabled by default, it must be enabled via the new factory knob.\ If you are upgrading from v3.9.5 or later, check that the cvmfsexec script is no more in the pre-reconfigure hooks directory.

Development Series

This is work in progress, so some pieces may be not so tested yet and the documentation out of sync. But it passed all out tests and is a good place to look for what is going on.

• v3_9_6 released on October 27, 2022 (Manual, Installation instructions)
  
  • Added token authentication to Glideins running in the Cloud (AWS and GCE). Now Glideins on all supported resources can authenticate back using IDTOKENS when using recent HTCSS versions.
  • Added `GLIDEIN_PERIODIC_SCRIPT` env variable to notify periodic custom scripts
  • Added the possibility to set the Glidein HTCSS TRUST_DOMAIN as attribute in the Frontend configuration
  • The Frontend configuration is now valid (reconfig/upgrade successful) even if some HTCSS schedds are not in DNS. Failing only if all schedds are unknown to DNS
  • Bug fix: Fixed `glidien_config` corrupted by concurrent custom scripts run via HTCSS startd cron (#163)
  • Bug fix: Fixed `setup_x509.sh` not to write to stdout when running as periodic script in HTCSS start cron (issues#162,#164)
  • Bug fix: Fixed setup_x509.sh creates proxy file in directory used for tokens (issue#201)
  • Bug fix: Fixed GLIDEIN_START_DIR_ORIG and GLIDEIN_WORKSPACE_ORIG values in glidein_config
  • Bug fix: Fixed unnecessary proxy/hostcert.pem workaround in frontend config (issue#66)
  • Bug fix: Fixed analyze_entries and python3 readiness (issue#194)
  • Bug fix: Fixed gwms-renew-proxies service should check if local VOMS cert is expired (issue#21)
  • Bug fix: Fixed python3 check return value in case of exception (PR#211)
  • Bug fix: Fixed list_get_intersection in singularity_lib.sh that was requiring python2 (PR#212)
  • Bug fix: Unset SEC_PASSWORD_DIRECTORY in the Glidein HTCSS configuration, was causing warnings for unknown files (PR#226)
  • Bug fix: HTCSS DC_DAEMON_LIST now is equal to DAEMON_LIST only in the Factory, in all other GlideinWMS components only selected HTCSS daemons are added explicitly to it (issue#205)
  • Bug fix: Working and local tmp directories are removed during Glidein cleanup also when the start directory is missing. This result in a loss of Glidein final status information but avoids sandbox leaks on the Worker Node. (issue#189)
  • NOTE: custom scripts should always read values via gconfig_get(). The only exception is the parsing or the line to get the add_config_line source file
  • NOTE: add_config_line is deprecated in favor of gconfig_add. Will be removed from future versions
  • NOTE: add_config_line_safe is deprecated in favor of gconfig_add_safe. gconfig_add is the recommended method to use also in concurrent scripts
  • NOTE: gconfig_add_unsafe, with a similar behavior to the former add_config_line, has been added. Its use is not recommended, unless absolutely sure that no script will be run in parallel
  • NOTE: Only the first collector in TRUST_DOMAIN is kept, following collectors are removed. This happens both in the Frontend token issuer and in the setting of the Glidein TRUST_DOMAIN (setup_x509.sh).

  • Factory now limits the speed at which it releases held glideins. After too many unrecoverable attempts, held glideins are removed.
  • Added support for Condor 7.8+
    KNOWN ISSUE: Only applies if you upgrade condor binaries in place without using the installer. Upgrading condor binaries for user pool and the wms collector with multiple schedds should not be done without corresponding changes to the condor configuration file. If the JOB_QUEUE_LOG is not correctly configured for each sched, condor queue will be corrupted for all the scheds
  • Glideins now support curl & data file transfer plugins in condor
  • New installations of factory and frontend services now communicate with condor daemons using TCP by default.

  • Bug Fix: Frontend now monitors the glideins correctly when the corresponding factory classad is missing
  • Bug Fix: Fixed factory logging. Factory can now correctly extract info from a voms proxy

  • KNOWN ISSUE: If the work directory has changed, frontend startup upgrade will not create the group directories and then the frontend will fail (silently). If you are changing directories (e.g. from a RPM upgrade), you should copy the group directories manually.

  • Fixed a security bug in the way certificate/proxy DN(s) are handled. If you are upgrading the installation rather than full install, you should patch the condor_mapfile used by Condor daemons in your installation using the convert_condormap tool available from the glideinWMS download page. For additional security, users should add new DN to the condor_mapfile only by using the glidecondor_addDN tool available in the glideinWMS/install directory.
