the workaround for -Wformat triggered -Wformat-nonliteral in turn.
so instead go back to using pragmas and add a proper gcc version check.
this also works with clang - mostly for qt-creator's code model, which
is clang-based.
amends/reverts 55e65147.
the assumption was that this wouldn't be needed, as maildir_store_msg()
reliably delivers a UID. however, if we crash right before the callback
can record that UID, we'd still use OPEN_FIND in the next run, which
requires the saved next UID.
an effect of 7ce658d is that we can index messages by UID rather than
content (or more specifically, subject). apart from being cleaner, it
allows duplicated subjects.
on modern systems, this makes it likely to end up on tmpfs, which is a
lot faster and ssd-friendlier.
the symlink is not deleted at the end, to minimize fs churn. that means
it will be dangling after a reboot, which gets fixed in the next run.
the operator was exactly inverted. that means that it actually wouldn't
compile with both older versions (that needed the aliases) and
potentially new versions (that will hide the data members - still not
the case as of 3.2).
amends 8a40554f0.
we failed to reset the box list pointer after freeing it, which would
lead to a crash.
we also failed to reset the listing status, which would lead to
malfunction if we hadn't already crashed.
this inlines imap_cleanup_store(), as there isn't much value in keeping
it. the message list is already freed when disowning the store anyway.
we need to deep-copy the struct hostent data, as otherwise the
concurrent connects will overwrite each other's lookup results.
this is a rather hypothetical fix, as the bug currently affects only
channels connecting two IMAP accounts, and only if the first host's
first address asynchronously fails to connect.
this is relevant only when listing an IMAP Store's contents, as that's
the only place where we aren't imposing the spelling ourselves.
we need to be careful not to treat our own canonical (prefix-stripped
and always slash-delimited) box names like that; codify that in
comments.
this reveals that commit 6f2160f1 may be deemed to have been incorrect -
the TODO item was ambiguous, and could quite possibly have meant this
fix. unsurprisingly, 380ccdd4 re-introduced it with more explicit
wording.
the query is untypical enough to have caused problems with davmail (when
we still used *:*) and mailo.com (until it got fixed), so better check
that the result (not) returned by the server makes sense.
we did already set up the timeout when starting to send commands, but so
far we did not reset it when succeeding to send out data. rectify that.
