* 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 Poldrack2022-03-231-0/+3
| | | | | | | | | | | | | 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: do not abort on malformed messagesRobin Jarry2022-02-061-1/+7
| | | | | | | | | | | | | | Some messages contain invalid headers, textproto.ReadHeader fails with an error: malformed MIME header key: From nobody Fri Jan 14 19 And all other messages of the selected folder are ignored. Return an explicit error message to the UI and continue processing other messages. This is consistent with what the maildir worker does. Signed-off-by: Robin Jarry <robin@jarry.cc>

* imap/fetch.go: report error when fetching headers failsBen Fiedler2020-04-241-3/+4
| | | | | Correct me if I'm wrong, but shouldn't this raise an error when it fails?
* Ignore missing message part in getDecodedPartAmir Yalon2020-03-091-1/+1
| | | | The code that calls this function handles nil without issues.
* Mark sent messages as "seen" in maildirGalen Abell2020-03-031-3/+3
| | | | | | | - Add maildir flags to complement a messages imap flags - Set the "seen" flag on sent messages when using the maildir backend - Cleanup AppendMessage interface to use models.Flag for both IMAP and maildir
* worker/imap: don't decode in FetchFullMessage.Reto Brunner2020-01-181-27/+2
| | | | | Doing that breaks `git am` as it expected the encoded variant. Same is probably true for any sort of signature validation (gpg / dkim)

* Factor IMAP-specific structs out of UI modelsBen Burwell2019-07-081-5/+5
| | | | | | | Before, we were using several IMAP-specific concepts to represent information being displayed in the UI. Factor these structures out of the IMAP package to make it easier for other backends to provide the required information.
* Use []uint32 instead of imap.SeqSetBen Burwell2019-07-081-8/+6
| | | | | | | | A sequence-set is an IMAP-specific implementation detail. Throughout the UI, aerc simply operates using lists of opaque identifiers. In order to loosen the coupling between the UI and IMAP in particular, replace most usages of imap.SeqSet with []uint32, leaving the translation to a SeqSet to the IMAP backend as needed.
* Factor UI models out of the worker message packageBen Burwell2019-07-081-15/+26
| | | | | | | | Before, the information needed to display different parts of the UI was tightly coupled to the specific messages being sent back and forth to the backend worker. Separating out a models package allows us to be more specific about exactly what a backend is able to and required to provide for the UI.

* worker/imap: use the IMAP connection from a single goroutineSimon Ser2019-04-291-41/+37
| | | | | | | | | | | | | Unfortunately, the IMAP protocol hasn't been designed to be used from multiple goroutines at the same time. For instance, if you fetch twice the same message from two different goroutines, it's not possible to tell whether the response is for one receiver or the other. For this reason, go-imap clients aren't safe to use from multiple goroutines. This commit changes the IMAP workers to be synchronous again (a command is executed only after the previous one has completed). To use IMAP from different threads, popular clients (e.g. Thunderbird) typically open multiple connections.
