Hi, and FYI,
there is a problem with message attachments, including those that
are added via *quote-as-attachment*: if you use the `~:' (or `~_')
tilde escapes during composition and switch off to a different
folder, then those attachments become invalid, or, worse, point to
false messages!
It is logically like that, but far from what i would consider to
be «sane behaviour».
Which would be of course if S-nail would automatically
do-the-right-thing behind the scenes. (The right thing: remember
it is a message attachment for the `~@' command, include the
*correct* message when sending the mail).
Unfortunately that cannot be implemented that easily with the
current codebase. What can be done:
. Detecting that a folder change happened and print a warning
message if there are existing message attachments.
This is what you get if you update to [master].
I thus highly recommend this.
If you don't care about code internals, have a good time and
stop reading, please.
. Automatic deselection of such an attachment upon folder
change.
Maybe i should have done that instead of only printing
a warning message, but i have decided the other way.
. Creating temporary files and storing the message content
therein, thus converting the RFC822 message attachment to
a file-attachment.
I have yet decided not to do this, because i really need
a holiday from S-nail.
It requires yet another attachment-handling mode to get this
right, so as to not introduce races (temporary files that
will not become cleaned up), but since the-right-thing is so
much more complicated to do (we need a completely different
handling of mailboxes that actually supports multiple
*simultaneously* opened mailboxes, including the yet
TODO-tracked intermediate "void" box; at that time it should
be possible to simply track the message attachment as
something like `FOLDERNAME#MSGNO') it may happen that i'll
implement it nonetheless for the next minor version.
Ciao,
