Sup guys, I have been working on backward synchronization for Maildir sources last week and I need your help to test and review the code. I pushed my commits (based on the 'next' branch) to my repo which you can find here [0] for the web interface and here [1] for the git address. The following is related to Maildir sources ONLY. So what does work and what does not (if you don't want to read this, scroll to the quick howto below): - Sup will now stay synchronized with your remote sources by detecting if a message has been remotely updated (ie: you change a flag from another client), these updates will be applied to your local index and your thread-view-mode buffers should be properly refreshed; - When a message is remotely deleted, it should now disappear from your index; - There is a new configuration option called "sync_back_to_maildir" which is false by default. When true, this option updates your actual Maildir files when you change a label, this is done in real time before being saved to xapian. So for instance if you use offlineimap the changes should be synched back to your IMAP server by the next poll in Sup (assuming that your before-poll hook runs offlineimap); - I wrote a "sup-sync-back-maildir" script that will synchronize all messages from your sources at once. This should be executed the first time BEFORE any polling, otherwise your IMAP server will be synched to your Sup index and if you did not used another client to mark your emails as read etc. (like me) and to update your IMAP server then you will lose all what you did in Sup (labels, etc.); - I added two new hidden labels in Sup: 'replied' and 'forwarded', they are automatically added when replying, forwarding or bouncing a message, this is to bring a better Maildir support to Sup, this should be invisible for users; - However you will probably lose all your remote 'replied' and 'forwarded' flags after your first backward synchronization to Maildir since Sup dropped these labels when it added your messages to xapian. - Moving a message from a Maildir source to another is not (yet?) supported. So, you should now be able to use multiple clients to handle your emails, for instance I can use gmail to mark messages as starred or so, it will be reflected in Sup. In the same way, if I mark a message as read in Sup it will appear as read in the gmail web interface. I tested this code with my main account (2 GB and like 15 Maildir sources) it works fine so far. Be warned that it is highly experimental, but if you use offlineimap it has a realdelete option so you *should* not lose any email, in the worst case it might mess your flags/labels up. I tested it only with offlineimap working with a gmail account. Quick howto: 1. Close sup 2. Backup your emails and your xapian index or use another Sup session 3. Clone the branch [1] 4. IMPORTANT: run "bin/sup-sync-back-maildir" to synchronize the Maildirs you wish, check the help 5. Add ":sync_back_to_maildir: true" to your config.yaml 6. Run and use sup Please test it and make reviews! :) NOTE: if you want this to work, get sure that you are not calling offlineimap with the '-q' option (as suggested in the wiki) otherwise it will ignore the flag updates on IMAP server, so check your before-poll hook.
