1966737 - Status update only shown when modal Folder Properties panel is dismissed

Status: RESOLVED FIXED

(Thunderbird :: Mail Window Front End, defect)

Description

[Francesco]

To trigger a situation where the status text should be updated, do one of the following:

Open the Folder Properties panel for either an IMAP folder or Newsgroup folder.
IMAP: Switch off synchronisation, then repair the folder. Status messages only arrive when the modal panel is dismissed.
News: Download a NG. Status messages only arrive when the modal panel is dismissed.

This may be related to bug 1901846 and its regressions.

Note that in TB 128 and TB 138 (current release) the message list is empty after a folder repair. It gets refreshed when the modal panel is dismissed. That fault is not present in TB 139 (current beta) or TB 140 (current Daily). The empty message list after compact was regressed by bug 1933104 (backported to 128.6.0), likely here:
https://hg-edge.mozilla.org/comm-central/rev/b0dd186860dd#l3.126

The fix is in this range:

likely bug 1959644.

So it appears that the modal panel blocks updates to the main window.

Actually, bug 1959644 is not the regressor here, in fact, it fixed a related issue. I just mentioned the related issue for completeness since the wider problem seems to be that a modal panel blocks updates to the main window.

After bug 1959644, modal dialogs are unable to refresh their opening windows.
Opening the dialog as dependent and freezing the about3Pane for user
interaction may be a suitable workaround.

This allows for immediate status bar updates and avoids the partially blank
thread pane when the "Repair Folder" button is clicked.
