* ui: avoid races with queue redrawRobin Jarry2023-04-271-15/+11
| | | | | | | | | | | | | | | | | | When calling ui.QueueRedraw() and a redraw is currently in progress, the redraw int value still holds REDRAW_PENDING since it is updated once the redraw is finished. This can lead to incomplete screen redraws on the embedded terminal. Even changing the redraw value before starting to redraw is exposed to races. Use a single atomic int to represent the state of the UI so that there cannot be any confusion. Rename the constants to make them less confusing.

* term: fix handling of failed commandTim Culverhouse2023-04-263-4/+5
| | | | | | | | | | | | | | | | | | | | | A panic occurs when a terminal is launched with a command that fails: :term blabla The underlying terminal does not need to be closed if the command failed to start: all resources are cleaned up upon failure to start already. Don't attempt to close terminal if the command didn't start. With the above fix in place, the tab will linger around until a redraw occurs, as there is nothing queuing a redraw on this behavior. Add a QueueRedraw in the tabs.Remove method to clean up the tabbar. The issue in tcell-term that causes this panic has been address there as well, released as 0.7.1. Update aerc's version.

* listDirectories: refactor listdirectories handlingTim Culverhouse2023-04-224-59/+69
| | | | | | | | | | | | | | | | | ListDirectories is called when connecting, reconnecting, and creation/deletion of a directory. The code is not in the same style as other areas of aerc. Refactor to match coding style of the rest of aerc by creating an Update function which handles necessary updates in the dirlist. This style does not use a callback, making it clearer what is happening in the message flow, and operates similar to how the msgstore receives updates. Use a map in the dirstore to reduce duplicate storage of directory names. Directly add or remove directories from the map when created / deleted to prevent a new ListDirectories message, and a flash of the UI.

| | | | | | | | | | | | | | | Create msgstores when a types.Directory message is received. This removes a quirk from the IMAP worker that msgstores are created on the first DirectoryInfo, and updated on the second. This path requires three messages in order to get an updated message store. By creating from types.Directory, we ensure that any subsequent DirectoryInfo can be routed to a msgstore. Remove the field DirInfo from the msgstore initializer, it isn't needed at initialization and isn't available with this refactor.

The status update comes with the following data: - Messages in the mailbox - Recent messages in the mailbox - Sequence number of the first Unseen message - Flags in the mailbox The data we actually we want to send to the UI: - Messages in the mailbox - Recent messages in the mailbox - Unseen messages in the mailbox Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
* msgstore: fetch message list based on OpenDirectory msgTim Culverhouse2023-04-227-13/+19
| | | | | | | | | | | | | | | Fetching the message list is done in a convoluted way. The UI receives a DirectoryInfo message, which creates a message store. It then receives a second DirectoryInfo (an oddity from the IMAP worker), and this DirectoryInfo is passed to the message store which then requests a fetch of the message list via store.Sort. Use the OpenDirectory done response to tell the message store to fetch messages. This makes the code easier to follow, and does not rely on quirks from the IMAP worker.

| | | | | | | | | | | | | | | | When running dynamic tui applications (such as btop, htop, etc.) in the embedded :terminal and focusing an account tab, every tui application change triggers a full redraw of the whole window.
