@rmol rmol commented Mar 31, 2020

Description

Avoid dirtying synced objects on update unless they've actually changed, and reduce the number of commits.

This is based on and should be reviewed after #1035.

Test Plan

Run the SD core dev server. Ensure that syncing completes, that the source list and conversation view populate correctly, and that you can reply to sources.

Checklist

If these changes modify code paths involving cryptography, the opening of files in VMs or network (via the RPC service) traffic, Qubes testing in the staging environment is required. For fine tuning of the graphical user interface, testing in any environment in Qubes is required. Please check as applicable:

  • I have tested these changes in the appropriate Qubes environment
  • I do not have an appropriate Qubes OS workstation set up (the reviewer will need to test these changes)
  • These changes should not need testing in Qubes

If these changes add or remove files other than client code, packaging logic (e.g., the AppArmor profile) may need to be updated. Please check as applicable:

  • I have submitted a separate PR to the packaging repo
  • No update to the packaging logic (e.g., AppArmor profile) is required for these changes
  • I don't know and would appreciate guidance

this lgtm, the name lazy_setattr made me think you were deferring setting the attribute but it's clear by the code and comment that it only sets attributes when the attribute on the server is different than what we store locally.
