Revisiting ancient issue - Apache2 100% CPU when competing for UW-IMAP
by Jacob Whatley 16 Nov '10

16 Nov '10

Okay, I didn't get any reply to my previous post (see below). The issue has now taken on a new element. I have confirmed what appears to be a race condition with multiple IMAP connections to UW-IMAP that occurs when a user is logged in to rcmail and begins to download a large attachment. If the attachment doesn't complete its download sequence before the next scheduled check (1, 3, or 5 min) for new mail, the subsequent login to the IMAP Server causes UW-IMAP to kill the process that is downloading the attachment in favor of the new login connection. Here is a maillog example: Sep 15 16:35:08 jwhatley imapd[70218]: Login user=jwhatley host=xxxxx.net [174.xxx.xxx.xxx] Sep 15 16:35:08 jwhatley imapd[70167]: Killed (lost mailbox lock) user=jwhatley host=xxxxx.net [174.xxx.xxx.xxx] I understand that UW-IMAP is old and that we should consider replacing with Dovecot or Courier, but I would like to explore the issue before initiating such a recommendation. I would really appreciate some feedback on this issue. Someone, perhaps Alec, could give me some guidance? More specifically and in the interim, I need to know where in the code to change the option 1, 3, 5 minute(s) so that I can increase the maximum available time between checking for new mail. Or, in the alternative, is there any provision within the code for suspending checks while attachments are being downloaded? Thank you all in advance for any assistance you can render.

We have a system in place to kill these resource hogs, but I want to see if anyone has a better solution, aside from dumping UW-IMAP. Thanks!

Folders Manager re-design
by A.L.E.C 16 Nov '10

16 Nov '10

I've no mockup, but I'll try to explain what changes in folders manager I'd like to provide. 1. UI: Add folder information/edition/creation frame on the right side of the list. Remove bottom box for folder creation. Add list options menu buttons (like in addressbook groups box), where we'll have create, edit, delete action (and maybe other provided by plugins, e.g. to remove all messages in a folder) 2. Folders list: Make it slim. It means I'd like to have only folder name (structured) and subscription checkbox. Drag-and-drop move supported. Would be nice to have quota indicator here too. 3. Folder frame: Here we'll have all information about a folder: name, messages count, threading. The folder frame will provide new possibilities. I'd like to implement per-folder sorting setting. Maybe list_cols config could be also per-folder. It will be a good place to implement features like: - ACL info/management - displaying of folder size - other provided by plugins -- Aleksander 'A.L.E.C' Machniak LAN Management System Developer [http://lms.org.pl] Roundcube Webmail Developer [http://roundcube.net] --------------------------------------------------- PGP: 19359DC1 @@ GG: 2275252 @@ WWW: http://alec.pl _______________________________________________ List info: http://lists.roundcube.net/dev/ BT/aba52c80

HTML icon entity lookbehind regex
by Brandon Davidson 11 Nov '10

11 Nov '10

Can you not do {min,max} in the lookbehind regex? ie, instead of this: $entity = '(?<!&' . '[a-zA-Z0-9]{2}' . '|' . '#[0-9]{2}' . '|' . '[a-zA-Z0-9]{3}' . '|' . '#[0-9]{3}' . '|' . '[a-zA-Z0-9]{4}' . '|' . '#[0-9]{4}' . '|' . '[a-zA-Z0-9]{5}' . '|' . '[a-zA-Z0-9]{6}' . '|' . '[a-zA-Z0-9]{7}' . ')'; Do this: $entity = '(?<!&' . '[a-zA-Z0-9]{2,7}' . '|' . '#[0-9]{2,4}' . ')'; Or is that the assertion format restriction you mention in the comment? -Brad _______________________________________________ List info: http://lists.roundcube.net/dev/ BT/aba52c80

imap server without thread support
by S c o t t K r a m e r 10 Nov '10

10 Nov '10

Hi, Could it be feasible to support message threading (with the current design) *without* server THREAD support? There is a feature request for IMAP thread support in hmailserver: http://www.hmailserver.com/forum/viewtopic.php?f=2&t=16893 [1] someone said this: Threading support should cache thread information in some permanent (persistent) form. If server just implements threading rfc, it will be slow and roundcube won't be able to use on large folders. Only some IMAP servers cache information in a way which is useful for threading in webmail clients. Thanks!!

images in html compose
by S c o t t K r a m e r 09 Nov '10

09 Nov '10

Hi, One other comment I've been getting with the current roundcube is not being able to drop (or cut & paste) an image into the compose window and having it just display inline... I realize this is tricky to do in a web app, are there any techniques out there to get this to work without a browser plugin etc... This is one of those general usability things that's frustrating when you go to do it and does not work... we all understand the attach image from url button, but most people do not-- Thanks!! _______________________________________________ List info: http://lists.roundcube.net/dev/ BT/aba52c80

delay when deleting messages
by Andres Sulleiro 02 Nov '10

02 Nov '10

Comment/question for you all. Right now I've observed the following behavior. Let me know if this is an accurate representation of how it works. When deleting a message in RC the selected message(s) gets removed from the list without an updating indicator but the system is still deleting the message and the message list is refreshed after that. This action can take a few seconds at times. Is this true? If so, I would like to comment that this gives the false impression that the moment the message disappears from the list, it's deleted and the list or the rest of the interface is ready to be used. Often times I find myself deleting messages and then selecting a new message to be deleted, causing my previous action to fail. It's really bothersome, specially as there's no real way of knowing when I can use the list again, making me take my chances. I've since started to look at the scrollbar in my message list to see when it redraws to know when I can move on to my next action. Is there a way to provide additional feedback to the user by showing a "deleting messages..." dialog or something? Or better yet, allow the process to run in the background without having to wait first, so this is not needed in the first place? Thank you all and keep up the good work!! // Andrés _______________________________________________ List info: http://lists.roundcube.net/dev/ BT/aba52c80
