* maildir: fix maildir folder listingJulian Pidancet2022-10-251-1/+1
| | | | | | | | | | | | | | | Previous change "maildir: hide invalid folders" prevents filepath.Walk from descending into directories that don't contain new/, tmp/ or cur/ because the WalkDirFunc returns filepath.SkipDir. We have to assume that these directories can be the parent of valid maildir folders even if they're not themselves valid maildir folders, so it is a mistake not to recurse into these subfolders. Fix it by returning nil instead of filepath.SkipDir in the WalkDirFunc.

* lint: check for bad white space habitsRobin Jarry2022-10-193-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A little coding hygiene cannot hurt. Add a simple awk script to check all source files for bad white space habits: - trailing white space - trailing new lines at the end of files - missing new line at the end of files - spaces followed by tabs The script outputs color when the terminal supports it. It exits with a non-zero code when there was at least one white space issue found. Call the script in the lint step. Example output of the awk script: config/default_styleset:1:# <-- trailing whitespace config/default_styleset:3:# <-- trailing whitespace doc/aerc.1.scd:78: Executes an arbitrary command in the background. Aerc will set the <-- trailing whitespace doc/aerc.1.scd:234: <-- trailing whitespace doc/aerc.1.scd:237: <-- trailing whitespace worker/types/thread_test.go:74: // return ErrSkipThread<-- space(s) followed by tab(s) worker/lib/testdata/message/invalid/hexa: trailing new line(s) Fix issues reported by the script. NB: The ENDFILE match is a GNU extension. It will be ignored on BSD-awk and trailing new lines will not be detected. The lint make target is only invoked on alpine linux which has GNU awk anyway. NB: Empty cells in scdoc tables require trailing white space... Avoid this by setting content in these cells. I don't really see a use for empty cells.

* 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.

* viewer: option to not mark message as seenKoni Marti2022-10-041-1/+4
| | | | | | | | | | | | | | | | | 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.

* worker: use container/list as job queueTim Culverhouse2022-10-041-2/+41
| | | | | | | | | | | | | | | | | The worker uses a buffered channel to queue tasks. Buffered channels are effective at FIFO, but are prone to blocking. The design of aerc is such that the UI must always accept a response from the backends, and the backends must always accept a request from the UI. By using buffered channels for both of these communication channels, a deadlock will occur. Break the chain by using a doubly linked list (container/list from the standard library) to queue tasks for the worker. Essentially, this is an infinitely buffered channel - but more memory efficient as it can change size dynamically.

* maildir: hide invalid foldersJulian Pidancet2022-10-031-0/+7
| | | | | | | | | | | | | | | | | The maildir worker currently populates the list of mail folders by listing all the filesystem subdirectories in the maildir directory. Although there's no official specification for maildir subfolders, they should all have cur/ new/ and tmp/ subdirectories to be valid. This patch prevents directories that don't have those subdirectories present on the filesystem from appearing in the account folder list. This is useful for example to prevent ".notmuch" and ".notmuch/xapian" from showing up in the folder list if using notmuch to index emails while using aerc's maildir backend.

The logging functions use a fmt.Sprintf call behind the scene which does not recognize %w. %w should be used in fmt.Errorf when you want to wrap errors.

* 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.

| | | | | | | | | | | | | Commit 716ade896871 ("worker: lock access to callback maps") introduced locks to the worker callback maps.

* notmuch: move logic for dynamic folders to backendKoni Marti2022-09-291-5/+9
| | | | | | | | | | | | | | | Moves logic for creating dynamic folders from the dirlist widget to the backend. Since dynamic folders are notmuch-specific, the notmuch backend should be responsible for correctly setting up those folders. It does that by sending two DirectoryInfos: the first to create the message store, the second to fetch the directory content. This approach also fixes a deadlock introduced by 716ade8968715 ("worker: lock access to callback maps").

* backends: send MessageInfoError on header fetching errorTim Culverhouse2022-09-255-8/+20
| | | | | | | | | | | | | | | | | | | | | 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 Culverhouse2022-09-202-11/+6
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | The built-in maildir.Dir.Move method performs an OS level file rename, which allows for preserving file creation time. Commit c98f70487417 ("move: enable MoveMessages from msgstore") enabled the use of the Move method for maildir. One particular maildir synchronizer (isync/mbsync) encodes the UID within the filename of the email and cannot recover if the UID is preserved during a move. mbsync encodes filenames like so: /path/to/email/{maildir-key},U={uid}:2,S OfflineIMAP encodes the UID within the filename, but also encodes a hash of the originating folder so that it can recover from a move without a rename of the underlying file. OfflineIMAP encodes like so: /path/to/email{maildir-key},U={uid},FMD5={folder-hash}:2,S Remove encoded UIDs of the form `,U={uid}` from filenames to prevent sync issues.

* parse: remove trailing whitespace from rfc1123z regexThomas Faughnan2022-08-221-1/+1
| | | | | | | | | | | | | | | | | | | | When there is no Date header in a message, aerc falls back to the Received header and tries to extract an rfc1123z date from it (introduced in commit d1600e46). The current regex for extracting the date incorrectly allows for trailing whitespace, causing time.Parse() to fail inside of parseReceivedHeader(). As a result, the message's date is shown as "???????????????????" in the message list and as "0000-12-31 07:03 PM" in the message view (the latter is likely related to the zero value of time.Time). Steps to reproduce: 1) Send yourself a message with no Date header, e.g. with msmtp: printf 'Subject: foo bar\n\nbody text\n' | msmtp --set-date-header=off me@example.com 2) Note the message's displayed date in aerc's message list and message view.

* maildir: implement MoveMessages handlingTim Culverhouse2022-08-222-0/+36
| | | | | | | | | | | | | Implement MoveMessages in the maildir worker. go-maildir supports Move operations by default, and is functionally equivalent to a OS-level rename. Creation date of the file is preserved by using Move, which is used by at least one maildir-to-IMAP synchronizer (isync/mbsync).

* 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.
