1.7.7

[1.7.7]

Fixed

• Bug that caused example workflows with a variable reference in their
  name to be listed by merlin example list with variable reference notation.
• Bug that caused requirements.txt files to be excluded from generated
  merlin example dirs.
• Bug that causes step restarts to lose alternate shell specification. Also added
  CLI test for this case.

Changed

• Default broker server password is now jackalope-password, since rabbit is
  currently accessed by developers only.

1.7.6

[1.7.6]

Added

• The first version of an optimization workflow, which can be accessed with
  merlin example optimization.
• Dev requirement library for finding dependencies (and make reqlist target)

Changed

• Improved warning and help messages about no_errors

Fixed

• Pinned to celery>5.0.3 so that merlin purge works again

1.7.5

[1.7.5]

Changed

• Now requiring Celery version 5.x.
• Further improvements to the null_spec example.

1.7.4

[1.7.4]

Fixed

• Users will no longer see the message, "Cannot set the submission time of ''
  because it has already been set", when tasks are restarted.
• Bug causing merlin restart to break.

Changed

• Improved internal logic beyond the crude fixes of the prior 2 patches.
• Added a developer cli test for the minimum valid spec format.

  a new null_chain and removes the now-redundant sim_spec.

Fixed

• Completed 1.7.2 fix for merlin run-workers.

1.7.2

[1.7.2] (hotfix)

• Fatal bug triggered by a spec missing the env or global.parameters sections.

1.7.1

[1.7.1] (hotfix)

Added

• When using the --samplesfile flag, the samples file is now copied to merlin_info for
  provenance.

Fixed

1.7.0

[1.7.0]

Added

• The ability to override any value of the celery configuration thru app.yaml in celery.override.

• Documentation on the new 3 types of provenance spec.

Fixed

• Flux test example data collection for new versions of flux.
• Fixed Docker ubuntu version.
• Removed expansion of env variables in shell sections (cmd and restart) of provenance
  specs. This allows the shell command itself to expand environment variables, and gives
  users greater flexibility.
• Allowed environment variables to be properly expanded in study description.name.
• Tilde (~) now properly expands as part of a path in non-shell sections.
• The rediss cert_reqs keyword was changed to ssl_cert_reqs.

1.6.2

[1.6.2]

Added

• The sample generation command now logs stdout, stderr, and cmd.sh to merlin_info/.
• 12 hidden test specs and associated cli tests, for cli tests with specs that we
  do not want in merlin examples.
• Inside merlin_info/, added provenance specs <name>.orig.yaml, <name>.expanded.yaml, and
  <name>.partial.yaml (identical to the original spec, but with expanded user variables).

Fixed

• Updated to new celery (4.4.5) syntax for signature return codes.
• Corrected prior visibility timeout bugfix.
• Fixed and reactivated 3 cli tests.
• Added the bank and walltime keywords to the batch slurm launch, these
  will not alter the lsf launch.

Changed

• Slightly improved logic by using regex to match variable tokens.
• Reduced instances of I/O, MerlinStudy logic is now in-memory to a greater extent.

1.6.1

[1.6.1]

Fixed

• Error if app.yaml does not have visibility timeout seconds

[1.6.0]

Added

• The broker name can now be amqps (with ssl) or amqp (without ssl).

• The merlin info connection check will now enforce a minute timeout
  check for the server connections.

Fixed

  eliminate race condition.
• A bug that did not change the filename of the output workspace nor of the provenance spec
  when a user variable was included in the description.name field.
• Temporarily locked Celery version at 4.4.2 to avoid fatal bug.

Changed

• The default rabbitmq vhost is now instead of /.
• Changed default visibility timeout from 2 hours to 24 hours. Exposed this in the config
  file.
• The monitor function will now check the queues to determine when
  to exit.
