#1275

Summarize your change.

  • We are now able to declare jobs from the configuration file (see cuesubmit/cuesubmit_config.example.yaml)
  • We can nest configuration files and use env variables.
  • The flag order is respected
  • Widgets are constructed according to each flag type:
  • The yaml syntax allows solo flags, pycue tokens, mandatory flags, no flags arguments and browsable fields.
  • Invalid text fields are red from the start
  • Added some unittests, would love some feedback on those.
  • Each job type can have limits and services preset.

Note

Question

  • Should we deprecate (or remove) the hardcoded commands ?
  • Are you ok with the commands syntax in the example yaml file ?

This branch is failing on CLA for some reason. @KernAttila I know it has been a while, but can you try following the CLA process again?

It looks like some errors emerged after merging master into this branch. Unit tests are failing with:

AttributeError: module 'cuesubmit.Constants' has no attribute 'RENDER_CMDS'

@DiegoTavares no worries, I'm currently fixing those. It's a bit hard to come back to this code after so long ^^ but we'll get there !
I will let you know when things are ready.

I tested a lot of scenarios, everything seems up to expectation with this feature.
There's an additional option in the config file: being able to have services and limits presets for each job type.
There is also more tooltips in the UI to help understand each widget.

IMPORTANT NOTE: I added the "Override Cores" feature in this branch as well, it goes with #1296 (rqd) and #1313 (cuebot)
I could move it to another branch if you prefer.

Looking back at this code, it introduces a mandatory argument "overrideCores" that will disrupt existing implementations relying only on pycue.
Another approach could be to test if "cores" is not None, meaning we explicitly override the job's cores value over the service one, thus making current codebases retro-compatible with this feature.
If "cores" is None, then we let the selected service handle that value.
What do you think @DiegoTavares @bcipriano @lithorus ?

Yeah, this change would break our pipeline today. I'd rather have it implemented as you suggested to make it retro-compatible.

The change is done and tested.
overrideCores stays in cuesubmit.

I don't see a problem in keeping #1296 and #1313 on this PR, as long as they get approved and merged beforehand

Fixes #1297

**Summarize your change.**
As in many render engines, we should be able to set a negative core
requirement.
  minCores=8 > reserve 8 cores
  minCores=0 > reserve all cores
  minCores=-2 > reserve all cores minus 2
  
This PR addresses this feature by handling negative core requests.
Cuebot will try to match this number against the number of cores on each
host.
The frame will be booked only if all cores are available in this
scenario.
If the host is busy (even slightly), the frame is **not** booked, to
avoid filling the remaining cores.

**Testing**
I would need some guidance to create proper tests for cuebot.

Update:
There is now a "ALL" text for zero cores, or "ALL (-2)" for negative
cores reservation.
