* imap: fix data race on seqMap arrayRobin Jarry2022-06-246-28/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are concurrent threads that are accessing and modifying IMAPWorker.seqMap (the mapping of sequence numbers to message UIDs). This can lead to crashes when trying to add and remove a message ID. panic: runtime error: index out of range [391] with length 390 goroutine 1834 [running]: git.sr.ht/~rjarry/aerc/logging.PanicHandler() logging/panic-logger.go:47 +0x6de panic({0xa41760, 0xc0019b3290}) /usr/lib/golang/src/runtime/panic.go:838 +0x207 git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages.func1() worker/imap/fetch.go:214 +0x185 created by git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages worker/imap/fetch.go:209 +0x12b Use a map which makes more sense than a simple array for random access operations.

* imap: add option to cache headersTim Culverhouse2022-06-226-12/+248
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add option to cache headers for imap accounts. Cache db is located at $XDG_CACHE_DIR/aerc/{account name}. The cache is cleaned of stale entries when aerc is first opened. Two new account level configuration options are introduced: * cache-headers (Default: false) * cache-max-age (Default: 30 days (720 hours)) The change in worker/imap/open.go is to set the selected directory. This is required to access the UIDVALIDITY field, which is used in combination with the message ID to form the key for use in the cache db. The key structure is: "header.{UIDVALIDITY}.{UID}" Where reasonable, cache does not stop aerc from running. In general, if there is an error in the cache, aerc should continue working as usual. Errors are either displayed to the user or logged. All messages are stored without flags, and when retrieved have the flags set to SEEN. This is to prevent UI flashes. A new method to FetchMessageFlags is introduced to update flags of cached headers. This is done asynchronously, and the user will see their messages appear and then any flags updated. The message will initially show as SEEN, but will update to unread. I considered updating the cache with the last-known flag state, however it seems prudent to spare the R/W cycle and assume that - eventually - all messages will end up read, and if it isn't the update will occur rather quickly. Note that leveldb puts a lock on the database, preventing multiple instances of aerc from accessing the cache at the same time. Much of this work is based on previous efforts by Vladimír Magyar.

* dirlist: update RUE counts for imap/maildir on move|copy|delete|archiveTim Culverhouse2022-06-073-13/+15
| | | | | | | | | | | | | | | | | | | When moving/copying/deleting/archiving a message in imap, the RUE counts displayed in the dirlist would not update properly. Maildir has (had) an implementation that recounts the entire directory and updates the DirectoryInfo after one of these actions. This patch implements a more efficient method of updating, and also enables it to apply to IMAP without any additional requests. Upon completion of the action, the counts are manually updated with the count of messages in the action and recent and/or unseen states of those messages. This is more efficient for maildir, because we aren't counting everything in the store. For IMAP, we get the updates for free because we are only performing the update after confirmation from the server that the action has happened.
