Not able to switch a sticky virtual module

[adrien-cotte]

Describe the bug

Switching two versions of a virtual module tagged sticky results in an error:

  ERROR: Unload of sticky module skipped

To Reproduce

Steps to reproduce the behavior:

$ module switch virt-mod/1.0 virt-mod/2.0
Switching from virt-mod/1.0 to virt-mod/2.0
  ERROR: Unload of sticky module skipped

Location and content of any modulerc or modulefile involved:

$ cat path/to/modulepath/virt-mod/.common
#%Module

$ cat path/to/modulepath/virt-mod/.modulerc
#%Module
module-tag sticky virt-mod
module-virtual virt-mod/1.0 .common
module-virtual virt-mod/2.0 .common

Expected behavior

When switching two versions of a sticky "usual" module, I get no error.
I expect having the same behavior while doing the same with virtual modules.

Error and debugging information

Additional context

I tried to put the tag in ~/.modulerc or in /home/acotte/workspace/module-5.4.0-dev/install/modulefiles/ but it changes nothing.

I can switch a "file version" of a module by a "virtual version" but the revert is not possible.

This issue was written after a Module mailling-list discussion with a similar subject.

[xdelaruelle]

Nice catch @adrien-cotte !

I am able to reproduce on my side. This issue is there since the introduction of the sticky feature (v4.7.0).

It is due to the logic of guessing the modulepath of a module based on its modulefile. It is used by isStickinessReloading procedure, but it cannot work with a virtual module.

https://github.com/cea-hpc/modules/blob/b78fcd48ea3d33e24723fe353fb29a8fe39cd441/tcl/modeval.tcl#L768-L770

[adrien-cotte]

What do you suggest?
Maybe we could just store in env the stickiness of a virtual module?

[xdelaruelle]

Stickiness of loaded modules are already stored in environment (through __MODULES_LMTAG variable).

isStickinessReloading searches for all the modulerc in the path toward the loaded module to get the module-tag definition. Then it is able to check if this sticky definition also matches the switched-on module to allow the operation.

What need to be done is to find the correct path toward modulercs in case of a virtual module.

[xdelaruelle]

In the end I added a new environment variable __MODULES_LMSTICKYRULE to track sticky definition when they are generic and permit to switch between module versions.
