* imap: fix flags updateKoni Marti2022-10-041-4/+4
| | | | | | | | | | | | | | | Fixes updating the flags in the imap backend. Before, the silent flag was set incorrectly by 75fc42e ("imap: send message info updates for bulk flag ops") which caused some imap servers to not send the updated flags. By disabling the silent flag, the flag update will return a corrsponding value that we can send back to the message store to update the flags correctly.

| | | | | | | | | | | | | | | | | Add option to open a message in the message viewer without setting the seen flag. Enables the message viewer to be used as a preview pane without changing the message flags unintentionally. Before, the message viewer would set the seen flag by default. The IMAP backend will now always fetch the message body with the peek option enabled (same as we fetch the headers). An "auto-mark-read" option is added to the ui config which is set to true by default. If set the false, the seen flag is not set by the message viewer.

* imap,smtp: add XOAUTH2 supportJulian Pidancet2022-10-013-0/+21
| | | | | | | | | | | | | | | | | | | | | Add XOAUTH2 authentication support for IMAP and SMTP. 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. Hopefully it shouldn't be too hard to maintain, being less than 50 SLOC.

* backends: send MessageInfoError on header fetching errorTim Culverhouse2022-09-251-4/+1
| | | | | | | | | | | | | | | | | | | | | When an error is encountered fetching a header, the backends respond with a type.Error worker message. On receipt of this message, the UI deletes all pending headers. The headers are all requested again as they remain on the screen, resulting in an infinite request loop - and an infinite logging loop. The user only ever sees the spinner unless they check the logs. A previous commit intended to fix this, however it introduced a regression where any message that was part of the fetch request would also be marked as erroneous. This commit is reverted with commit 2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48"). Send an erroneous message info message from the backend when an error is encountered for a specific UID.

* 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.

* seqmap: refactor seqmap to use slice instead of mapTim Culverhouse2022-08-035-48/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The imap worker's seqmap is represented as a map of sequence number to UID. This presents a problem when expunging group of messages from the mailbox: each individual expunge decrements the sequence numbers by 1 (for every sequence number greater than the expunged). This requires a looping around the map to update the keys. The use of a map also requires that both the sequence number and the UID of a message be known in order to insert it into the map. This is only discovered by fetching individual message body parts (flags, headers, etc), leaving the seqmap to be empty until we have fetched information about each message. In certain instances (if a mailbox has recently been loaded), all information is loaded in memory and no new information is fetched - leaving the seqmap empty and the UI out of sync with the worker. Refactor the seqmap as a slice, so that any expunge automatically decrements the rest of the sequences. Use the results of FetchDirectoryContents or FetchDirectoryThreaded to initialize the seqmap with all discovered UIDs. Sort the UIDs in ascending order: IMAP specification requires that sequence numbers start at 1 increase in order of ascending UID. Add individual messages to the map if they come via a MessageUpdate and have a sequence number larger than our slice. Update seqmap tests with new logic.

| | | | | | | | | | | | | | | | | | | | | | When opening unread emails from certain people (I won't name any names, sorry), an annoying error message is displayed on the status line: could not get section &imap.BodySectionName{BodyPartName: imap.BodyPartName{Specifier:"", Path:[]int(nil), Fields:[]string(nil), NotFields:false}, Peek:false, Partial:[]int(nil), value} This does not occur for already read messages. This issue is similar to the one that was fixed in commit 8ed95b0d2ad2 ("imap: avoid crash when replying to unread message"). This happens because the flags are updated in the callback that receives the message itself. It causes the flag update to arrive in the same channel/request. Ignore the messages that have an empty body (i.e. only containing flag updates). This is inherently racy but there seems no way to get rid of these extra messages.

* imap: add option to cache headersTim Culverhouse2022-06-225-12/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

* imap: avoid crash when replying to unread messageRobin Jarry2022-04-281-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running `:reply -q` on an unread message, aerc crashes after opening the editor: panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x5d1019] goroutine 63 [running]: bufio.(*Reader).fill(0xc000086ef8) /usr/lib/golang/src/bufio/bufio.go:106 +0xd9 bufio.(*Reader).Peek(0xc00020bef8, 0x1) /usr/lib/golang/src/bufio/bufio.go:144 +0x5d github.com/emersion/go-message/textproto.ReadHeader(0xc00004a700?) emersion/go-message@v0.15.0/textproto/header.go:525 +0x5f git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessageBodyPart.func1(0xc00056e280) worker/imap/fetch.go:99 +0x1ab git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages.func1() worker/imap/fetch.go:178 +0xd7 created by git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages worker/imap/fetch.go:172 +0x12b This happens because the flags are updated in the callback that receives the message itself. It causes the flag update to arrive in the same channel/request. Ignore the messages that have an empty body (i.e. only containing flag updates). This is inherently racy but there seems no way to get rid of these extra messages. Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Connor Kuehl <cipkuehl@gmail.com>
* logging: added a log on panicMoritz Poldrack2022-03-234-0/+12
| | | | | | | | | | | | | Since panics still regularly "destroy" the terminal, it is hard to get a stack trace for panics you do not anticipate. This commit adds a panic handler that automatically creates a logfile inside the current working directory. It has to be added to every goroutine that is started and will repair the terminal on a panic. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>

* imap: start reconnect when initial connect failsKoni Marti2022-02-201-3/+11

* imap: reconnect with exponential backoffKoni Marti2022-02-191-4/+28
| | | | | | | | | | | | | waits an increasing amount of time before attempting a reconnect. Wait is capped at 16s. Prevents many reconnect attemps in a short time period. Fixes commit 05ad96a30cb8 ("imap: improve reconnect stability") that improved the reliability of the reconnect mechanism but did not implement controls to prevent the triggering of too many reconnects within a short period of time.
