* logging: rename package to logRobin Jarry2022-12-021-15/+15
| | | | | | | | | | Use the same name than the builtin "log" package. That way, we do not risk logging in the wrong place.

* logging: homogenize levelsRobin Jarry2022-12-021-6/+7
| | | | | | | | | | | | | | | | | | The main goal is to ensure that by default, the log file (if configured) does not grow out of proportions. Most of the logging messages in aerc are actually for debugging and/or trace purposes. Define clear rules for logging levels. Enforce these rules everywhere. After this patch, here is what the log file looks like after starting up with a single account: INFO 2022/11/24 20:26:16.147164 aerc.go:176: Starting up version 0.13.0-100-g683981479c60 (go1.18.7 amd64 linux) INFO 2022/11/24 20:26:17.546448 account.go:254: [work] connected.

* message-info: add explicit References fieldTim Culverhouse2022-11-091-0/+4
| | | | | | | | | | Add an explicit References field to message info. This is useful for storing information needed for threading without storing all of the header values, keeping system RAM usage lower.

* cache: fetch flags from UITim Culverhouse2022-09-201-10/+4
| | | | | | | | | | | | | | | 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.

* imap: prevent deadlock from posting actions to selfTim Culverhouse2022-09-201-1/+2
| | | | | | | | | | | | | | | | The IMAP worker has a few methods that post a new Action to itself. This can create a deadlock when the worker.Actions channel is full: The worker can't accept a new Action because it's trying to post an action. This is most noticeable when cached headers are enabled and the message list is scrolled fast. Use a goroutine to post actions to the worker when posting from within the worker.

* logging: use level-based logger functionsRobin Jarry2022-07-231-14/+15
| | | | | | | | | | | | Do not pass logger objects around anymore. Shuffle some messages to make them consistent with the new logging API. Avoid using %v when a more specific verb exists for the argument types. The loggers are completely disabled (i.e. Sprintf is not even called) by default. They are only enabled when redirecting stdout to a file. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>
* imap: add option to cache headersTim Culverhouse2022-06-221-0/+174
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.
