2022-01-19maildir,notmuch: avoid leaking open filesNguyễn Gia Phong
Previously, Message.NewReader returned the wrapped buffered reader without a reference to the opened file, so the files descriptors were left unclosed after reading. Now, the file reader is returned directly and closed on the call site. Buffering is not needed here because it is an implementation detail of go-message. Fixes: https://todo.sr.ht/~rjarry/aerc/9
2022-01-19imap: auto-reconnects on connection errorKoni Marti
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>
2022-01-19imap: emits connection error on logoutKoni Marti
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>
2022-01-19imap: fix panic when sending multiple connect cmdsKoni Marti
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>
2022-01-15Revert "imap: attempt automatic reconnection on error"Robin Jarry
This reverts commit c605ada3ddc7569ebfc153b07db12a21b30d0569. This breaks reading message bodies. I am not sure why, I'll take some time to fix it later. Signed-off-by: Robin Jarry <robin@jarry.cc>
2022-01-14imap: attempt automatic reconnection on errorRobin Jarry
Attempt to reconnect to the server when there is an unexpected disconnection or network error. Use the Client.LoggedOut() channel which is closed when the connection is closed. This patch is rather flaky and is certainly bugged. However, it is a start. Signed-off-by: Robin Jarry <robin@jarry.cc>

2021-12-07imap: use low level tcp connectionRobin Jarry
In preparation for tcp keepalive options, we need access to the net.TCPConn object associated with an IMAP connection. The only way to do this is to create the connection ourselves. No functional change. Signed-off-by: Robin Jarry <robin@jarry.cc>
2021-12-07imap: move connect procedure into a dedicated functionRobin Jarry
This will prepare for extra tcp connection options support and for automatic reconnect. No functional change. Signed-off-by: Robin Jarry <robin@jarry.cc>
2021-12-06maildir: watch for message renamesRobin Jarry
Messages flags can also be changed without changing directories. Changing flags in maildirs means renaming the message files. Also take renames into account.

2021-12-06maildir: watch for external changesRobin Jarry
When a maildir is synchronized by an external process while aerc is running (e.g. mbsync), some emails may be moved out of "new" to "cur" or completely deleted. These deletions are ignored and aerc may assume these messages are still here, leading to errors. Take file deletions into account. Also, add "cur" to the watched folders since these can be modified as well. Signed-off-by: Robin Jarry <robin@jarry.cc>

2021-11-13notmuch: allow sort by file orderKalyan Sriram
When using the notmuch backend, it often makes more sense to sort folders (actual virtual folders, or queries) by the order specified in the query-map file, rather than alphabetically. This patch introduces a configuration option (disabled by default) that allows this. Additionally, due to the notmuch backend previously using maps (which are order-undefined) to store the list of queries, default query selection on aerc startup fluctuated. This patch fixes that by using slices to store query order.
2021-11-13notmuch: allow empty searchesKalyan Sriram
Don't error on empty search terms, just don't filter by anything and return all items matching the current querymap
2021-11-13messages: allow displaying email threadsy0ast
Display threads in the message list. For now, only supported by the notmuch backend and on IMAP when the server supports the THREAD extension. Setting threading-enable=true is global and will cause the message list to be empty with maildir:// accounts.

2021-11-01maildir: track the recent flag correctlyReto Brunner
In the maildir worker we manually need to track the Recent flag in order for the notification command etc to work. Push that responsibility to the container, we must make sure to manually add the flag though if one grabs the message info.
2021-04-28notmuch/maildir: remove double emit of the dirinfoReto Brunner
There was some bug which could be worked around by double emitting an event. However that proofed to be brittle: We send the first message here from the worker goroutine: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g= o#L306 Then Tick() is waked in the main goroutine and calls ProcessMessage: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/widgets/account.go#L100 ProcessMessage in the main goroutine reads types.Message state with msg.getId() and msg.InResponseTo(): https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#= L74-76 Meanwhile in the worker goroutine we call PostMessage for a second time with a pointer that points to the *same* previous message that ProcessMessage is reading: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g= o#L306 The second PostMessage call makes writes to message while ProcessMessage in the main goroutine is possibly reading: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#= L59 This led to a data race in the event loop Reported-By: Wagner Riffel <w@104d.net>

Trims whitespace in list of excluded notmuch tags. This allows a comma separated list with spaces to be correctly processed.
2020-12-02notmuch: remove gc close hooksReto Brunner
We frequently had issues with notmuch segfaulting and my guess is that this was due to the garbage collection magic used in the module. This changes to a fork that ripped the functionality out.

We made a new type out of go-message/mail.Address without any real reason. This suddenly made it necessary to convert from one to the other without actually having any benefit whatsoever. This commit gets rid of the additional type

2020-08-31handle message unknown charset errorJeff Martin
This change handles message parse errors by printing the error when the user tries to view the message. Specifically only handling unknown charset errors in this patch, but there are many types of invalid messages that can be handled in this way. aerc currently leaves certain messages in the msglist in the pending (spinner) state, and I'm unable to view or modify the message. aerc also only prints parse errors with message when they are initially loaded. This UX is a little better, because you can still see the header info about the message, and if you try to view it, you will see the specific error.
2020-08-20base models.Address on the mail.Address typeReto Brunner
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.
2020-08-19Add support for :rmdirARaspiK
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.
2020-08-10improve date parsing for notmuch/maildirReto Brunner
If a message date would fail to parse, the worker would never receive the MessageInfo it asked for, and so it wouldn't display the message. The problem is the spec for date formats is too lax, so trying to ensure we can parse every weird date format out there is not a strategy we want to pursue. On the other hand, preventing the user from reading and working with a message due to the error format is also not a solution. The maildir and notmuch workers will now fallback to the internal date, which is based on the received header if we can't parse the format of the Date header. The UI will also fallback to the received header whenever the date header can't be parsed. This patch is based on the work done by Lyudmil Angelov <lyudmilangelov@gmail.com> But tries to handle a parsing error a bit more gracefully instead of just returning the zero date.
2020-08-07notmuch: manually close notmuch objectsReto Brunner
There seems to be some race with the automatic closing that should happen in theory... close it manually where we can to avoid the issue
2020-07-27maildir: Provide nicer error message on invalid urlTero Koskinen
If accounts.conf contains an invalid maildir url, return a nice error instead of panicking. Log a couple of different error cases to provide extra information about the error to the user.
2020-07-27Remove hard coded bodystruct path everywhereReto Brunner
Aerc usually used the path []int{1} if it didn't know what the proper path is. However this only works for multipart messages and breaks if it isn't one. This patch removes all the hard coding and extracts the necessary helpers to lib.
2020-07-25Add flag based search optionsTobias Wölfel
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.
2020-07-19Only send directory info once from maildirAndrew Jeffery
The directory info only needs to be sent once for all the messages, this reduces unnecessary messages being sent which could lock up the ui.

2020-07-11Make it easier to debug date parsing errorsLyudmil Angelov
When message dates failed to parse, the error displayed would try to include the time object it failed to obtain, which would display as something like 0001-01-01 00:00:00 UTC, which isn't of much help. Instead, display the text we were trying to parse into a date, which makes the problem easier to debug.
2020-07-08Add additional flagging functionalityARaspiK
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.
