* 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.

* imap: improve reconnect stabilityKoni Marti2022-02-061-7/+19
| | | | | | | | | | | | | | | | improves the robustness of the imap reconnect feature which was introduced in commit beae17a6da37 ("imap: auto-reconnects on connection error"). If a connection error is emitted, the message list is cleared and a corresponding error message is shown in the ui. Status bar is updated as well. Upon reconnect, the directories and the message list will be re-fetched (same behavior as the connect command). Reconnect can be enabled and disabled with the connect and the disconnect commands.

* 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: auto-reconnects on connection errorKoni Marti2022-01-191-2/+24
| | | | | | | | | if the worker emits a connection error, the ui will automatically send back a reconnect command. The worker then establishes a new connection. Auto-reconnect is disabled when the user sends the disconnect command. Fixes: https://todo.sr.ht/~rjarry/aerc/1 Signed-off-by: Koni Marti <koni.marti@gmail.com>
* imap: emits connection error on logoutKoni Marti2022-01-191-0/+29
| | | | | | | | implements a new connection error message. This allows the worker to emit a connection-related error message to the ui when the imap client closes the loggedOut channel. Signed-off-by: Koni Marti <koni.marti@gmail.com>
* imap: fix panic when sending multiple connect cmdsKoni Marti2022-01-191-15/+26
| | | | | | | | | | | fixes the panic when the user sends multiple connect commands and is already connected. The panic is caused by closing an already closed channel. This happens when the idle re-init code is not executed, e.g. when there's a return statement in the switch block. A defer func() before the switch block will prevent this. The existing behavior of only creating a new idleStop channel when properly connected is preseverd. Signed-off-by: Koni Marti <koni.marti@gmail.com>

| | | | | | | | | | | | | Attempt to reconnect to the server when there is an unexpected disconnection or network error.

* base models.Address on the mail.Address typeReto Brunner2020-08-201-2/+1
| | | | | | | | | | | | This allows us to hook into the std libs implementation of parsing related stuff. For this, we need to get rid of the distinction between a mailbox and a host to just a single "address" field. However this is already the common case. All but one users immediately concatenated the mbox/domain to a single address. So this in effects makes it simpler for most cases and we simply do the transformation in the special case.
* Add support for :rmdirARaspiK2020-08-192-0/+21
| | | | | | | | | | | | | | | | | | | | | The `:rmdir` command removes the current directory (`-f` is required if the directory is not empty). This is not supported on the notmuch backend. An issue with the maildir backend is that some sync programs (e.g. offlineimap) may recover the directory after it is deleted. They need to specifically be configured to accept deletions, or special commands need to be executed (e.g. `offlineimap --delete-folder`) to properly delete folders. A danger of using this on the IMAP backend is that it is possible for a new message to be added to the directory and for aerc to not show it immediately (due to a slow connection) - using `:rmdir` at this moment (with `-f` if the directory already contains messages) would delete the directory and the new message that just arrived (and all other contents). This is documented in aerc(1) so that users are aware of possible risks.
* Add flag based search optionsTobias Wölfel2020-07-251-1/+24
| | | | | | | Provide search and filter with the option to specify more flag based conditions. Use '-x <flag>' to search for messages with a flag (seen, answered, flagged) and '-X <flag>' to search for messages without a flag.
* Add additional flagging functionalityARaspiK2020-07-082-7/+6
| | | | | | | | | | | | | | More mail flags can now be set, unset, and toggled, not just the read/seen flag. This functionality is implemented with a new `:flag` and `:unflag` command, which are extensions to the matching `:read` and `:unread` commands, adding support for different flags. In fact, the `read`/`unread` commands are now recognized aliases to `flag`/`unflag`. The new commands are also well documented in aerc(1). The change mostly extends the previous read/unread setting functionality by adding a selection for the flag to change.

* remove the dirInfoUpdateRequest functionalityReto Brunner2020-02-291-2/+0
| | | | | The notmuch worker followed suit in handling the dirInfo submission manually. That removes the last user so we might as well remove the functionality.
* lib/msgstore: debounce directoryUpdateRequestsReto Brunner2020-02-251-0/+2
| | | | | | | | Apparently sending an event for every incoming messageInfo slows down the application significantly. Therefore this slows down the emmision rate, on the cost of being out of date in some cases.
* imap: fix double closing idleStopReto Brunner2020-02-161-2/+4
| | | | | | The idle restart code is at the end of handleMessage in the worker. However if an unsupported msg comes in, we returned early, skipping the re-init. That lead to a crash due to double closing idleStop in the next iteration.

* decode(RFC 2047) imap headers to fix encoding in subject & filenamesLeszek Cimała2019-12-071-5/+25
| | | | | | | | | | | | | | | | | | Me again, this time fixing encoding of subjects and attachments. It was problem in IMAP backend. While other backends user MessageInfo() function which generates MessageInfo decoded via go-message methodes, IMAP worker is creating MessageInfo directly, so all non-utf8 subjects and filenames were in raw form. This patch fixes it. Not sure if we should care about errors (if DecodeHeader fails it returns raw string back). >From what I see, this should solve all encoding problem (tested only IMAP). So, now I can focus on features. ;-) Have a great weekend! Leszek
* worker/imap: Fix seqMap race conditionKevin Kuehler2019-11-101-1/+3
| | | | | | | | | | When deleting a message, sometimes FetchDirectoryContents will fire. FetchDirectoryContents will return a smaller set of UIDs since messages have been deleted. This operation races with fetching from the seqMap in client.ExpungeUpdate. Only recreate the seqMap if it can grow so that messages will continue to be expunged.

* Change search flagsJeffas2019-09-201-2/+6
| | | | | | | | This changes the search flags for maildir and imap backends. They now no longer use -t for searching all text. This seems to make more sense as being the targeted recipient. I have similarly added Cc for -c. The text search now resides under -a for all text.
