Currently only trashed or hidden messages are deleted by
DeleteMsgOnImap, so it is safe to remove database records.
It is planned to delete messages on IMAP server after
user-configurable time to cleanup the server even for messages
displayed in chats. For such messages, we unlink them from the
Message-ID, but keep the database record to display them.
Mutable UID reference is removed. Instead, ImapActionResult is
returned immediately.
If message has changed and UID does not correspond to expected
message, ImapActionResult::Failed is returned. Temprorary IMAP errors
result in ImapActionResult::RetryLater.
On the job side, ImapActionResult::RetryLater does not result in
immediate job retry anymore. Instead, job is retried with a backoff.
In addition to moving the message into trash chat, this function
removes message text to make sure the message does not remain in the
database. Only the information necessary to delete message from the
server and avoid redownloading it should be kept, such as Message-Id
and IMAP UID.
CString::yolo was still used in the ffi, this was an unsafe
transitional thing. To remove it there were two choices: 1. make
errors in creating CStrings hard errors or 2. try and be as lenient as
possible. Given the to_string_lossy() convention adopted in the ffi
this choose the lenient option and simply skips over embedded null
bytes, leaving the rest of the strings intact.
Thus now CString::new_lossy(). It's only used for .strdup() however
so no longer a public trait.
This also cleans up the public visibility of things in the strings.rs
file:
- Rename StrExt/OptStrExt traits to what they actually do: provide
.strdup() -> Strdup/OptStrdup.
- dc_strdup() should be an implementation detail, replace all usages
with Strdup.strdup() method.
- Only allow visibility inside the crate for all things.
- Reduce visibility to only the module for things not used in lib.rs.
after fixing some issues wrt ecc keys, see #1319,
and waiting some time (three core releases, two ios/android/desktop releases),
it is now the time to switch again to ecc keys again,
after the first attempt was stopped in #1319
before, the list was empty
and trying to send to groups that only contain SELF lead to a crash.
in theory, this happens for both, bcc_self enabled or not, however,
if bcc_self was disabled (default setting),
things worked as the whole mimerendering was skipped on a higher level.
also, the saved-messages-chat was not affected as this was checked explicitly.
this pr changes the mimerendering so that From: is used as To:
if there is no recipient-list and the messasge will be sent to SELF only.
