* logging: homogenize levelsRobin Jarry2022-12-021-1/+1
| | | | | | | | | | | | | | | | | | The main goal is to ensure that by default, the log file (if configured) does not grow out of proportions. Most of the logging messages in aerc are actually for debugging and/or trace purposes. Define clear rules for logging levels. Enforce these rules everywhere. After this patch, here is what the log file looks like after starting up with a single account: INFO 2022/11/24 20:26:16.147164 aerc.go:176: Starting up version 0.13.0-100-g683981479c60 (go1.18.7 amd64 linux) INFO 2022/11/24 20:26:17.546448 account.go:254: [work] connected.

* msgviewer: show error if MessageInfo has errorTim Culverhouse2022-11-091-2/+9
| | | | | | | | | | | | | | | | | MessageInfo structs can be returned from the workers with parser errors. MessageViews were previously prevented from opening if the error field was not nil, however the addition of message view splits have allowed these messages to have split views created. A panic can occur if a split is open and one of these messages is scrolled over. Prevent access to MessageInfo methods if the Error field is set. Display the error to the user in the split view. The partSwitcher will be nil if an error is set: check for this condition before calling it's methods.

* command/help: remove helpClose functionTim Culverhouse2022-10-191-20/+0
| | | | | | | | | | | | | The helpClose function is used to call UpdateScreen on MessageViewer, which has the effect of invalidating and redrawing the message view. This logic is redundant with the addition of tcell-term and the main event loop. Remove the helpClose calls. Remove the UpdateScreen methods from messageviewer: those functions are only used by the helpClose function.

| | | | | | | | | | The ThisDayTimeFormat and friends are missing from the message view which just uses the message list's default setting.

* msgviewer: simplify filter and pager command handlingTim Culverhouse2022-10-181-92/+30
| | | | | | | | | | | | | | | | | | | Refactor the filtering and paging logic to use several fewer goroutines. Fixes data race condition with the timing of filter -> pager -> terminal, can be found when switching message views fast. Check if filter -> pager process is currently running before calling it to start again. Fixes data race between fetching message body and terminal starting. Both can initiate the copying process, and for long running filters and fast message fetching, it is possible to have fetched a message but still be running the filter when the terminal starts. Move StripAnsi to it's own file in lib/parse, similar to the hyperlinks parser. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

* terminal: protect calls to terminal methods throughout aercTim Culverhouse2022-09-191-1/+3
| | | | | | | | | | | | | | A race condition can occur when a PartViewer is closing and also working on a draw. The closing process sets the terminal to nil, which will create a panic. This can be tested in development by setting the timer in the main aerc tick loop to something very low (1 ms for example). One other unprotected call to terminal exists in the composer widget. Check that the terminal is not nil before calling methods on it. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

This avoids issues where the embedded terminal widget is destroyed but the pager process does not know about it and dies in agony, writing over aerc's UI: Vim: Caught deadly signal HUP Also, it may avoid leaving child processes as zombies without giving them a proper burial.

* term: replace go-libvterm with tcell-termTim Culverhouse2022-09-141-0/+4
| | | | | | | | | | | | | | | | Replace go-libvterm package with tcell-term. go-libvterm provides the embedded terminal for aerc. It uses a statically linked C library, requiring CGO. tcell-term is written in pure go and is written to be portable with tcell applications by implementing the tcell Widget interface. This allows the terminal to take a view (which aerc already supplies) and draw directly to it, as well as issue tcell Events to a Watcher. Enable setting cursor shapes in embedded terminals.

DKIM, SPF and DMARC authentication methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to have an explicit list of trustworthy hostnames before displaying the authentication results. Be aware that the authentication headers can be forged. To display the results for a specific authentication method, add the corresponding name to the layout of headers in the viewer section of aerc.conf, e.g. to display all three, use: header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC More information will be displayed when "+" is appended to the authentication method name, e.g. DKIM+ or SPF+ or DMARC+. Also, add the trustworthy hosts per account with the trusted-authres parameter, e.g. trusted-authres = * to trust every host or use regular expressions for a finer control. Multiple hosts can be entered as a comma-separated list. Authentication results will only be displayed when the host is listed in the trusted-authres list.

| | | | | | | | | | | | | | | | When trying to search in less, keys bound to viewer functions can't be used as part of the search query, which makes the search useless. Add a view::passthrough binding mode and a :toggle-key-passthrough command go toggle in and out of that mode. By default, typing '/' in the viewer is bound to enabling key passthrough and automatically inserting '/', to easily enter "less" search mode. When in the passthrough mode, all bindings are ignored by default. The default binds.conf only defines a single keybinding in that mode: <Esc> to get back out. $ex is bound to <C-x> to allow typing colons.
