* dirtree: modify drawing of the dirtreeTim Culverhouse2023-05-162-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the dirtree drawing structure to be a bit more compact. The dirtree is drawn with one column left for a flag, which indicates if a parent is collapsed or expanded. Only draw the "flag" when the parent is collapsed. Change the flag to a '+' character to match common UI patterns of expanding lists having a '+' box. Don't draw the '>' character in the dirtree. This character is nice in the threaded message view, but clutters up the dirtree. I know this is a matter of preference, but this approach is similar to most other UI tree view and gives the dirtree an extra column of space. The original dirtree looks like this: ┌Inbox ├─>Sub └─>Sub And collapsed: -Inbox This patch changes it to: Inbox ├─Sub └─Sub And collapsed: +Inbox Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

* maildir: fix FSWatcher handling of eventsTim Culverhouse2023-05-111-40/+22
| | | | | | | | | | | | | | | | | | | | Commit ef4504e6baf5 ("maildir: fix handling of FSEvents") ambitiously tried to fix handling of file system events by handling different events in "proper" ways. Distributions and OSes report these FSEvents differently which creates a large amount of edge cases on what the right handling of each individual event should be. Revert part of ef4504e6baf5 which attempts to issue different messages based on the event. Add a debounce to file system events and always trigger a Refetch of the message list. This still fixes one of the "fixes" the referenced patch attempted at, where the UI was only told to refetch if the message count increased (but if messages disappeared externally, the maildir never updated).

* msgstore: fix handling of deleted messagesTim Culverhouse2023-05-111-5/+4
| | | | | | | | | | | | | | | | | | The msgstore trims the uid list when a message was deleted. It does so whether the message is in the message store or not. If the message was already deleted and a MessagesDeleted is received, the store will be trimmed regardless. This can cause spurious emails to be removed from the msgstore due to a race condition with the fs watcher / imap update channel. When a message is deleted, the UI will received two MessagesDeleted and in some cases trim the list, removing too many emails. Fix the handling of deleted messages so that the uid list is rebuilt of all messages except the deleted ones specifically.

* filters: fix option parsing on arm cpusRobin Jarry2023-05-113-37/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | When running colorize or wrap on ARM, both programs exit immediately displaying their help message whatever the provided arguments. This is caused by an implicit downcast of the getopt return value. On most architectures, char is signed by default. On ARM, char is unsigned for performance reasons. Since the signed int return value of getopt is forced into a char, the results differ on ARM compared to x86. * Add -Wconversion -Warith-conversion to CFLAGS in CI builds to ensure catching such issues in the future. * Fix all -Wconversion -Warith-conversion reported issues. * Wide char functions need to deal with wint_t and wchar_t and it is guaranteed that a wchar_t can always fit into a wint_t. Add explicit casts to silence the reported warnings.

* maildir: fix handling of FSEventsTim Culverhouse2023-04-282-8/+44
| | | | | | | | | | | | | | | | | | | Maildir uses a filesystem watcher to watch the currently selected directory for changes, updating the UI as necessary. Not all changes get updated based on the current logic. Send a MessageInfo if the event was a Rename. Send a MessagesDeleted if the event was a Remove. Tell the UI to refetch the list if the event was a Create. Note: This leads to some unnecessary fetching in the UI, as renames also come with a Create event in most cases. Koni suggested sending the MessageInfo and having the UI perform a binary search and inserting the message in the proper position. This is optimization is left out of this series, with a TODO left in the code.

| | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | 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.
