Custom modules are only resynced to minions at highstate

[dqminh]

Description of Issue/Question

Custom modules are only resynced to minions at highstate. The documentation said

Modules placed in _modules/ will be synced to the minions when any of the following Salt functions are called:

state.apply
saltutil.sync_modules
saltutil.sync_all

Before the introduction of state.apply it was state.highstate which is much clearer. However if we can fix the loading process of modules so it can be automatically resynced/reloaded it would be great too.

Setup

• Custom modules stored in states/_modules

Steps to Reproduce Issue

• Update a custom module
• Run a specific state on the minion without saltutils.sync_modules|all first.

@dqminh are you stating that the custom modules are not being synced on state.highstate? or that you would like custom state modules to be synced when running state.sls. Sorry for the confusion just want to make sure I understand what your issue is and what you are proposing as the fix. Thanks

[dqminh]

@Ch3LL its confusing when the documentation stated that custom modules are sync at state.apply, but state.apply can be run either in highstate mode ( same as state.highstate ) or in multiple states mode. Custom modules can only be synced in the former cases, not the latter.

There are a few things i would like to be fixed:

• changing documentation to clarify that custom modules are only synced in highstate
• syncing changed custom modules when running individual states if possible.

@dqminh thank you very much for clarifying. It makes sense now. Agreed we should update the docs to show the other instances that custom modules are synced such as highstate and add ability to sync modules when running individual states thanks. Since these are two separate issues 1. a documentation bug and 2. feature request, would you mind opening another issue to request the ability to sync custom modules on state.sls please? Thanks and we will track the documentation bug here.
