* split: refactor to prevent stuck splitsTim Culverhouse2022-12-252-3/+17
| | | | | | | | | | Refactor split logic (again...) to prevent stuck splits. Use callback from msgstore.Select to tell the split which message to display. This keeps the account from having to track displayed messages, which prevents race conditions in certain situations.

* threads: rebuild server threads when updating threadsTim Culverhouse2022-12-142-2/+13
| | | | | | | | | | | | | | | | | The addition of the iterator factory added a thread builder when using server side threads. A conditional for returning UIDs when selecting messages would check for a not-nil store.builder, and return UIDs from the thread builder. When using server side threads, there was no mechanism to update the threads after a message deletion or move, so store.Uids() would return a stale set of UIDs. This would allow the user to "select" a deleted email (the cursor would disappear). Add an update mechanism for the threads if server side threads are enabled. When building thread UIDs, check for deleted or hidden threads.

* split: refactor split update logicTim Culverhouse2022-12-141-0/+3
| | | | | | | | | | | | | | | | | | | | | | Refactor split update logic to more simply update the split. Through the evolution of the split logic, additional variables were stored within the account which allows for cleaner updating of the split. Compare selected UID instead of pointer to message when deciding not to update split. Allow splits to be created and closed when no message is selected. The split will be filled with a ui.Fill (blank). The user will only see a border at the split location when no message is selected. Rename clearSplit to closeSplit, as it is only used in the case when the user doesn't want a split anymore. Ensure that the selected UID is reset to the magic UID when there are no messages left in the message store.

* config: make various sections accessible via global varsRobin Jarry2022-12-145-26/+27
| | | | | | | | | | | | | | | | | | | | There is only one instance of AercConfig which is associated to the Aerc widget. Everywhere we need to access configuration options, we need somehow to get a reference either to the Aerc widget or to a pointer to the AercConfig instance. This makes the code cluttered. Remove the AercConfig structure and every place where it is referenced. Instead, declare global variables for every configuration section and access them directly from the `config` module. Since bindings and ui sections can be "contextual" (i.e. per account, per folder or per subject), leave most local references intact. Replacing them with config.{Ui,Binds}.For{Account,Folder,Subject} would make this patch even more unreadable. This is something that may be addressed in the future.

* msgstore: set store.uids in threaded directoriesTim Culverhouse2022-12-071-0/+1
| | | | | | | | | | | | | | | Commit b46e57324394 ("store: fix server-side threads toggling") introduced a regression where the uids of the store were not set after rebuilding the threads. This would result in a flash of pending messages as they were repopulated. This also would not properly remove messages which were moved out of the store (deleted, moved, archived) with server side threading. Re-add the line that sets the store.uids.

* invalidatable: always mark ui as dirty OnInvalidateTim Culverhouse2022-10-072-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | The Invalidatable struct is designed so that a widget can have a callback function ran when it is Invalidated. This is used to cascade up the widget tree, marking things as Invalid along the way so that only Invalid widgets are drawn. However, this is only implemented at the grid cell level for checks if the cell is invalidated -- and the grid cells are never set back to a "valid" state. The effect of this is that no matter what is invalidated, the entire UI gets drawn again. The calling through the Invalidate callbacks creates *several* race conditions, as Invalidate is called from several different goroutines, and many widgets call invalidate on their parent or children. Tcell has optimizations to only rerender screen cells that have changed their rune and style. The only performance penalty by redrawing the entire screen for aerc is the operations *within the aerc draw methods*. Most of these are not expensive and have relatively no impact on performance. Skip all of the OnInvalidates, and directly invalidate the UI when DoInvalidate is called by a widget. This reduces data races, and simplifies the widget redraw logic signficantly.

Although XOAUTH2 is now deprecated in favor of OAuthBearer, it is the only way to connect to Office365 since Basic Auth is now completely removed. Since XOAUTH2 is very similar to OAuthBearer and uses the same configuration parameters, this is basically a copy-paste of the existing OAuthBearer code. However, XOAUTH2 support was removed from go-sasl library, so this change reimports the code that was removed from go-sasl and offers it a new home in lib/xoauth2.go.
