* lint: check for bad white space habitsRobin Jarry2022-10-191-2/+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.

* lib: parse address header fields to utf-8Koni Marti2022-09-291-6/+9
| | | | | | | | | When parsing address header fields, the field charset is automatically decoded to UTF-8. If the charset is unknown, use the raw field value.

* 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.

* mbox: implement an mbox backend workerKoni Marti2022-07-141-0/+254
| | | | | | | | | | | | | | | | | | | | | | | | | Implement an mbox backend worker. Worker can be used for testing and development by mocking a backend for the message store. Worker does not modify the actual mbox file on disk; all operations are performed in memory. To use the mbox backend, create an mbox account in the accounts.conf where the source uses the "mbox://" scheme, such as source = mbox://~/mbox/ or source = mbox://~/mbox/file.mbox If the mbox source points to a directory, all files in this directory with the .mbox suffix will be opened as folders. If an outgoing smtp server is defined for the mbox account, replies can be sent to emails that are stored in the mbox file.

* parse: fix content-type parsing errorKoni Marti2022-06-073-1/+96
| | | | | | | | | | | If an error occurs when parsing the content-type, check if the content-type is quoted; if so, remove quotes. If this is not the case, then return a text/plain content-type as a sane fallback option, so that the message can be at least viewed in plaintext.

* pgp: ensure CRLF line endings in pgpmail readerKoni Marti2022-04-251-0/+11
| | | | | | | | | | | | | | | | | | Ensure CRLF line endings in the pgpmail reader. Fix the pgp signature verification for maildir and notmuch. These backends do not return the full message body with CRLF line endings. But the accepted OpenPGP convention is for signed data to end with a <CR><LF> sequence (see RFC3156). If this is not the case the signed and transmitted data are considered not the same and thus signature verification fails.

* maildir,notmuch: avoid leaking open filesNguyễn Gia Phong2022-01-192-13/+8
| | | | | | | | | | 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

* handle message unknown charset errorJeff Martin2020-08-313-2/+99
| | | | | | | | | | | | | | 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.
* base models.Address on the mail.Address typeReto Brunner2020-08-202-12/+2
| | | | | | | | | | | | 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.
* improve date parsing for notmuch/maildirReto Brunner2020-08-101-24/+49
| | | | | | | | | | | | | | | | | | | | 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.
* Remove hard coded bodystruct path everywhereReto Brunner2020-07-271-6/+4
| | | | | | | 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.
* Make it easier to debug date parsing errorsLyudmil Angelov2020-07-111-1/+1
| | | | | | | | | 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.
