Cylc Project VC 2 April 2020
(Extenuating circumstances: everyone attending from home, Covid-19 lockdown
just instituted over much of the world :grimace:)
7.8.5
- We should release this soon, just get MH’s PRs in first.
- HO: on the mysterious orphaned job log tail processes on job hosts, it seems
to be sufficient to configure cylc to run
tail via the timeout command
(tested). DM may test at Met Office.
7.8.x and 7.9.x
- instead of continuing to duplicate PRs to the 7.9.x branch, which is mildly
painful, we should just delete 7.9.x and re-branch from 7.8.x after changes
(there shouldn’t be many more changes on 7.x) and cherry-pick the Jinja2
upgrade commit.
8.0a2
- Conda Forge setup done, pretty much good to go
- Just need to update the meta data in the conda recipe
- BK to document the release process clearly, and make sure that others are
recorded as maintainers on the conda repos.
- Get it done before the Platforms changes go in
- How to document use (and meaning of alpha status) for users who install by
conda?
- Cylc web site and Discourse
Spawn on Demand
- HO has all unit tests and most of the test battery working on the SoD branch
- time consuming due to many tests relying on SOS semantics and task pool
content.
- Last(??) major unsolved problem is absolute dependence.
- HO to document this and possible solutions on the SoD proposal doc
- Need to make a decision on this pretty soon.
- OS agreed if reflow is fine and all test battery functionality is covered
there’s no obvious reason not to go ahead with this.
Misc
- OS good idea to simplify the test battery by providing a utility to fake the
DB task pool table to any state, and take the scheduler there directly via
restart.
- Some discussion on a “universal delimiter” for suite/task IDs. DS’s new ID
form is good (hierarchy) but can’t be used on the command line (the delimiter
is the shell pipe character). More thought needed.
- Agreed to get rid of the “task owner” concept in Cylc, used to run jobs on
other user accounts
- better to use ssh config for this (need to document for users)
- Agreed to move cylc-flow to GH actions soon
Next meeting?
Early May (ish).
