There is not much we can do +yet about dealing with the error itself, and marking read is probably +not important enough to warrant keeping a queue of pending changes or +anything. + +However this commit changes it so that + +- we do try and make future mark read tag changes. + +- we display the tag state correctly: i.e. we don't display the tag as + deleted (no strike through) + +- and since we know the tag change failed we can try to mark this + message read in the future. Indeed, since the code uses the + post-command hook we will try again on the next keypress (unless the + user has left the message). + +We indicate to the user that these mark read tag changes may have +failed in the header-line and by a message in the echo area. +--- + +Hi + +The best level of user notification in case of an error is +unclear. The best we came up with on irc is this one: + +On first error, the headerline is changed to say (in warning face) +that some mark read tag changes may have failed. + +On each error, which will occur on each call to +notmuch-show-command-hook (so roughly after each keypress) we write +the error to the error buffer and we send a message to the echo area. + +In principle I would like to send a single message to the echo area +and have it persist for a few seconds. However, the echo area is +cleared after each keypress so this seems difficult. Moreover, this +clearing means if we send the message a single time and the user +enters the message with repeated cursor-downs then the message will +disappear as soon as it is displayed. + +In the future we might want to modify the error code to be something like the +message buffer and say "last error repeated x times", but that can +come later. + +Best wishes + +Mark + + + emacs/notmuch-show.el | 17 ++++++++++++++++- + 1 file changed, 16 insertions(+), 1 deletion(-) + +diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el +index fea39fa..406f418 100644 +--- a/emacs/notmuch-show.el ++++ b/emacs/notmuch-show.el +@@ -1701,12 +1701,27 @@ user decision and we should not override it." + (notmuch-show-mark-read) + (notmuch-show-set-prop :seen t))) + ++(defvar notmuch-show--seen-has-errored nil) ++(make-variable-buffer-local 'notmuch-show--seen-has-errored) ++ + (defun notmuch-show-command-hook () + (when (eq major-mode 'notmuch-show-mode) + ;; We need to redisplay to get window-start and window-end correct. + (redisplay) + (save-excursion +- (funcall notmuch-show-mark-read-function (window-start) (window-end))))) ++ (condition-case nil ++ (funcall notmuch-show-mark-read-function (window-start) (window-end)) ++ ((debug error) ++ ;; The call chain from notmuch-show-mark-read-function writes ++ ;; and error to the error buffer before calling the error, so ++ ;; we do not need to do that here.
