* threadbuilder: store uid/thread associationKoni Marti2023-07-162-35/+39
| | | | | | | | | | | | | | Store the association between uids and threads in a map instead of just having the threads in a slice. This simplifies the lookup of a thread when we have an uid and we can avoid computationally expensive tree walks. The threadbuilder will rebuild the uids from the given thread structure. Hence there is no need now to keep a threads slice around. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc> Tested-by: inwit <inwit@sindominio.net>

* templates: process reversed names betterVitaly Ovchinnikov2023-06-292-3/+135
| | | | | | | | | | | | | | | | | | | Change the behavior of `names`, `firstnames` and `initials` functions in templates so they better process names formatted like this: "Last Name, First Name" Basically, if the name contains one (and only one) comma, its parts are flipped so the first name always goes first. This helps to do "Hello Name" in templates regardless of the name format in email address. Also if the template uses a full name it will make it "Hello FirstName LastName" instead of "Hello LastName, FirstName". Add tests to cover more complex names in the future.

* msgstore: delete pending headers when done or cancelledTim Culverhouse2023-06-201-1/+2
| | | | | | | | | | | | | | The msgstore keeps a map of UIDs it has requested headers for. The map is only cleared of pending headers when either an error or a valid header is received. This can lead to pending headers not being removed from the list (and therefore never re-requested) if a user has navigated away from the directory before the response is received. Delete the pending headers list if the request is finished or cancelled.

* logging: remove ultra verbose trace logsRobin Jarry2023-06-121-3/+1
| | | | | | | | | | | | | | | | | Every message exchanged between the UI and the worker(s) is logged at least twice with some obscure IDs and struct pointer names. When enabling trace logging, this floods the files for very little or no benefit and makes the meaningful logging message hard to catch. Also, other messages tend to flood the output for no specific reason. These are most of the time leftovers from the development process and are not useful for tracking potential issues. Remove these.

* ui: fix deadlocks in message channelRobin Jarry2023-05-204-43/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several ways the ui message channel can fill up leading to deadlocks. 1) Invalidate() changes the value of uiState to DIRTY. The following call sequence: QueueRedraw() Invalidate() QueueRedraw() Leads to multiple nil messages being queued in the message channel whereas one could assume that the second QueueRedraw() would do nothing. This is caused by the tri-state nature of uiState. 2) We use the same channel to convey state change, keyboard events and redraw requests. Since a keyboard event almost always triggers a redraw, we end up trying to append a redraw message in the same goroutine that reads from the channel. This triggers a deadlock when there are more than 50 pending messages. Solve the issue by using multiple channels, one per type of message that needs to be sent to the main ui thread. Remove QueueRedraw() and merge its functionality in Invalidate(). Only use a DIRTY/CLEAN state to determine if something needs to be queued in the redraw channel. Use a channel for quitting instead of an atomic. Restructure some code functions to have a cleaner API. Use a for loop in the main thread and select from all channels.

* templates: use template interface consistentlyKoni Marti2023-05-161-48/+72
| | | | | | | | | | | | | | | Use the template interface consistently. Before, we have exported the state.TemplateData struct and used it in most places instead of the models.TemplateData interface. This lead to some inconsistencies, i.e. Role() has been defined on the exported struct but not on the interface. Unexport the state.TemplateData struct, add a DataSetter interface to set the data needed for the template data and call the Data() method which returns a models.TemplateData interface when the template data is needed.

* textinput: improve stemmingKoni Marti2023-05-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | Fix cursor index after stemming and reset it to the position where the completion should occur. Only stem to add more information and not remove any user input. Stemming is activated on the textinput line when the user presses the Tab key. The idea of stemming is to adjust the textinput line to the common ground (="the stem") of the completions options. When the stemmed input line is set, however, the cursor will be moved to the end of the line if there is a text part on the right side of the cursor where the completion should occur. Another Tab press will activate the onStem function again, which then removes the right part of the text input leading to the loss of the user input. This can be prevented by moving the cursor to the place of the completion after stemming. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

Examples: :filter -f {{<Tab> will show the possible template data fields and functions :filter -f {{index (.To|email) 0}}<Tab> will show the value of the template expression in the completion list Pressing <Tab> twice after a completed template expression will substitute the expression with its value. :{{if match .Folder "INBOX"}}check-mail{{else}}cf INBOX{{end}} Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
* msgstore: fix handling of deleted messagesTim Culverhouse2023-05-111-5/+4
| | | | | | | | | | | | | | | | | | The msgstore trims the uid list when a message was deleted. It does so whether the message is in the message store or not. If the message was already deleted and a MessagesDeleted is received, the store will be trimmed regardless. This can cause spurious emails to be removed from the msgstore due to a race condition with the fs watcher / imap update channel. When a message is deleted, the UI will received two MessagesDeleted and in some cases trim the list, removing too many emails. Fix the handling of deleted messages so that the uid list is rebuilt of all messages except the deleted ones specifically.

* ui: avoid races with queue redrawRobin Jarry2023-04-271-15/+11
| | | | | | | | | | | | | | | | | | When calling ui.QueueRedraw() and a redraw is currently in progress, the redraw int value still holds REDRAW_PENDING since it is updated once the redraw is finished. This can lead to incomplete screen redraws on the embedded terminal. Even changing the redraw value before starting to redraw is exposed to races. Use a single atomic int to represent the state of the UI so that there cannot be any confusion. Rename the constants to make them less confusing.

Refactor to match coding style of the rest of aerc by creating an Update function which handles necessary updates in the dirlist. This style does not use a callback, making it clearer what is happening in the message flow, and operates similar to how the msgstore receives updates. Use a map in the dirstore to reduce duplicate storage of directory names.

* msgstore: fetch message list based on OpenDirectory msgTim Culverhouse2023-04-221-2/+5
| | | | | | | | | | | | | | | Fetching the message list is done in a convoluted way. The UI receives a DirectoryInfo message, which creates a message store. It then receives a second DirectoryInfo (an oddity from the IMAP worker), and this DirectoryInfo is passed to the message store which then requests a fetch of the message list via store.Sort. Use the OpenDirectory done response to tell the message store to fetch messages. This makes the code easier to follow, and does not rely on quirks from the IMAP worker.

| | | | | | | | | | | | | | | | | | | | | In order to make automation easier, it's useful to be able to send commands to aerc via IPC. This can be done by calling the aerc binary followed by a colon and the command to run. For example: aerc :read && aerc :remark && aerc :archive month Security to ensure no malicious commands are run is deferred to the user. By default the socket is only writable by the user. This is considered sufficient as the potential harm an attacker gaining write-access to a user's session can cause is significantly greater than "can delete some emails". To ensure users with an according threat model, it is possible to disable command IPC. mailto-handling is unaffected even though it works over IPC as it is absolutely non-destructive.
