1836391 - Unified folders mode randomly shows and doesn't show chevrons for smart folder

Status: RESOLVED FIXED

(Thunderbird :: Folder and Message Lists, defect, P2)

Description

[Alessandro Castellani [:aleca]]

STR:

• Start in All folder modes
• Activate Unified folder modes

See how the special folders all have the chevron even if you only have 1 account.

• Restart Thunderbird

The special folders don't have the chevron.

Not severe but kinda annoying, and slightly related to bug 1832698 as the list is not populated on first select when the chevrons are visible.

I have a theory that if Unified is the first active mode, its init method could run before the account manager is ready and therefore the folders that should be displayed don't exist. If that's true then I think that calling something such as MailServices.accounts.allServers; at the top of the function would solve the problem. But it's only a theory, I've not managed to reproduce the bug yet.

Attachment: Bug 1836391 - Before loading virtual folders, ensure that all real folders exist. r=#thunderbird-reviewers

If LoadVirtualFolders is called before the real folders properly exist, the missing folders are
removed from the virtual folder by ParseAndVerifyVirtualFolderScope and lost forever. This can be
difficult to reproduce as most real folders are brought into existence by earlier code, but it can
be seen in a new profile with only a local mail account and the unified folders mode enabled.
