This patch:
1. Copies unsent messages to the outbox before attempting to deliver
them with SMTP
2. Deletes those messages once they're sent, or leaves them if an error
occured
3. Updates the message list to make it obvious when there are unsent
messages in the outbox
This one is a bit of a doozy. A summary of the changes:
- Session has grown storage for attachments which have been uploaded but
not yet sent.
- The list of attachments on a message is refcounted so that we can
clean up the temporary files only after it's done with - i.e. after
copying to Sent and after all of the SMTP attempts are done.
- Abandoned attachments are cleared out on process shutdown.
Future work:
- Add a limit to the maximum number of pending attachments the user can
have in the session.
- Periodically clean out abandoned attachments?
This can happen if an email is deleted by an external client, and this
change fixes a template crash in such cases.
I elected to display (deleted email) rather than to hide deleted
messages so that, if the message is unread, it provides an explanation
for your inbox showing $n unread emails where $n > number of non-deleted
emails.
This partially addresses ~migadu/alps#121
This patch contains a whole lot of layout improvements for the alps
theme, mainly replacing the table soup with flexbox and CSS grids, and
fixing up a number of loose ends. This gives us a lot more flexibility
over how the page is laid out. I also cleaned up a lot of other
low-hanging fruit in the layout & styles.
This causes the mailbox to automatically reload the page every 60
seconds, without JavaScript.
This also updates the base template data to include the full URL, and
replaces the earlier "Path" field with a pre-split array of path
components, which is more immediately useful to most templates given the
limitations of string munging with text/template primitives.
