* ui: avoid panic when terminal window is shrunkJason Stewart2022-09-261-2/+4
| | | | | | | | | | | When using a tiling window manager, aerc terminal dimensions may be greatly reduced after a new window has been created by :open. When the ui attempts to render to formerly-valid coordinates, SetCell & Printf may panic. Replace panic() with no-op in both functions to prevent aerc from crashing after a window shrink.

* backends: send MessageInfoError on header fetching errorTim Culverhouse2022-09-255-8/+20
| | | | | | | | | | | | | | | | | | | | | When an error is encountered fetching a header, the backends respond with a type.Error worker message. On receipt of this message, the UI deletes all pending headers. The headers are all requested again as they remain on the screen, resulting in an infinite request loop - and an infinite logging loop. The user only ever sees the spinner unless they check the logs. A previous commit intended to fix this, however it introduced a regression where any message that was part of the fetch request would also be marked as erroneous. This commit is reverted with commit 2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48"). Send an erroneous message info message from the backend when an error is encountered for a specific UID.

* cache: fetch flags from UITim Culverhouse2022-09-203-11/+29
| | | | | | | | | | | | | | | When cached headers are fetched, an action is posted back to the Worker to immediately fetch the flags for the message from the server (we can't know the flags state, therefore it's not cached). When scrolling, a lag occurs when loading cached headers because the n+1 message has to wait for the flag request to return before the cached headers are retrieved. Collect the message UIDs in the UI that need flags, and fetch them based off a debounce timer in a single request. Post the action from the UI to eliminate an (ugly) go routine in the worker.

| | | | | | | | | | | | | | When errors occur during a fetch header request, the requested headers are deleted from pending and no information is given to the UI. Spinners keep spinning, and ultimately as the view is refreshed, the headers are fetched again. This can lead to infinite loops, and extremely long logs.

* terminal: don't invalidate on EventWidgetContentTim Culverhouse2022-09-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The terminal widget uses it's own internal event handler to redraw itself for improved performance. The event handler draws, updates the screen, and invalidates. The last invalidate is redundant: Invalidating has the result of telling aerc to redraw the screen. A race condition can occur where an event is emitted from the terminal and the terminal is closed before the event is handled. This results in handling the event after the terminal is closed, and a panic: panic: Attempted to invalidate unknown cell goroutine 54685 [running]: git.sr.ht/~rjarry/aerc/lib/ui.(*Grid).cellInvalidated(0xc00b0a34a0, {0xbb8f10?, 0xc00360cd80}) git.sr.ht/~rjarry/aerc/lib/ui/grid.go:287 +0x175 git.sr.ht/~rjarry/aerc/lib/ui.(*Invalidatable).DoInvalidate(0xc0002e7900?, {0xbb8f10?, 0xc00360cd80?}) git.sr.ht/~rjarry/aerc/lib/ui/invalidatable.go:22 +0x82 git.sr.ht/~rjarry/aerc/widgets.(*Terminal).invalidate(...) git.sr.ht/~rjarry/aerc/widgets/terminal.go:93 git.sr.ht/~rjarry/aerc/widgets.(*Terminal).HandleEvent(0xc00360cd80, {0xbb4ba0?, 0xc006022690?}) git.sr.ht/~rjarry/aerc/widgets/terminal.go:192 +0xd2 github.com/gdamore/tcell/v2/views.(*WidgetWatchers).PostEvent(...) github.com/gdamore/tcell/v2@v2.5.3/views/widget.go:113 github.com/gdamore/tcell/v2/views.(*WidgetWatchers).PostEventWidgetContent(0xc0001b9360, {0xbbc950?, 0xc0001b9320}) github.com/gdamore/tcell/v2@v2.5.3/views/widget.go:123 +0x12b git.sr.ht/~rockorager/tcell-term.(*Terminal).run.func1() git.sr.ht/~rockorager/tcell-term@v0.1.0/terminal.go:117 +0x9d created by git.sr.ht/~rockorager/tcell-term.(*Terminal).run git.sr.ht/~rockorager/tcell-term@v0.1.0/terminal.go:104 +0x110 Don't invalidate on EventWidgetContent.

The tests are given names to be easier identifiable.
